A method of operating a single-tuner radio includes tuning into a first frequency. A pause in a first signal associated with the first frequency is detected. Tuning is switched from the first frequency to a second frequency. A signal quality metric for the second frequency is measured. Tuning is switched from the second frequency to the first frequency.

A method of performing alternate frequency switching in a radio includes tuning the radio to a primary frequency. A candidate alternate frequency is identified. It is determined whether the candidate alternate frequency is a third order inter-modulation artifact. Tuning is switched from the primary frequency to the candidate alternate frequency only if it is determined in the determining step that the candidate alternate frequency is not a third order inter-modulation artifact.

A partition formed of two spaced panels forming outer wall surfaces. The partitions are spaced by a paper honeycomb structure, passages in the honeycomb being substantially perpendicular to the panels. There are elongated H-shaped members fitted on each of two opposite ends of the panels, the H-bar of the members being adjacent the panel end edges. There is a partition stabilizing bar extending centrally between the panels and extending through a space between two sections of the honeycomb. The stabilizing bar is threaded at both ends and secured to and through the H-bars of the H-shaped members so as to prevent bowing or collapse of the partition in the direction of the bar. The method includes the steps of putting the partition together, particularly the steps of inserting the stabilizing bar between the honeycomb sections after they have been secured between the panels and of securing the stabilizing bar to the H-shaped members.

A working table or desk having a grating for vertical storage of material in elongated form, such as rolled blueprints. The table has a vertically directed opening with grating forming rods extending thereacross to form spaces for inserting rolled documents for storage. A container is positioned below the opening on the floor to receive the lower ends of the material. The opening has vertical surfaces having spaced horizontally directed holes therein. Each hole on each surface is in alignment with an opposite hole in an opposite surface to receive the rods forming the grating. One of each pair of oppositely aligned holes is deeper than the other to receive a coil spring. Each rod is inserted into a deeper hole to be in abutment with the spring, the spring being compressed to permit the entry of the rod across the opening and when so compressed the other end of the rod is within the opening and in position to be forced into the opposite hole by the bias of the spring. The spring thus holds each rod in place. In order to provide an arrangement of crossing rods to form the grating, holes in faces adjacent to faces having a first group of holes are bored at a higher level so that the rods may fit above the first rods and cross the latter.

A flow control and safety valve for oil wells where control of flow in the casing annulus is accomplished with a wire-line retrievable device. A basic valve structure provides for control of flow in the casing annulus by means of a control line to the surface. A number of additional functions can be added to the basic valve structure to accomplish control of flow through the tubing string and can accommodate control of dual and triple zone recovery. These additional functions are accomplished by landing additional wire-line retrievable valves within the basic structure whereby independent control of the annulus and tubing string flows is possible, at the same time affording increased flow diameters for a greater volume of production in a given casing size.

A locking system for retaining a pair of modular wall partitions in locked relationship. The locking system includes a threaded insert means in the first partition end aligned with a bolt extending through the end of the second partition. As the bolt is threaded into the insert the respective ends of the partitions are drawn together to lock the same in a rigid connection one to the other.

A strap is secured across the passenger compartment of an automobile at a position behind the front seat backs and close to the top of the front seat backs. The strap is secured around the doorposts of a 4-door car to prevent the seat backs from collapsing backward due to impact on the car from the rear.

A radio includes a first tuner and a second tuner. A processor compares a first perceivable volume level of a station tuned by the first tuner to at least one second perceivable volume level of at least one background station tuned by the second tuner. The processor enables automatic volume knob changes using a pre-calibrated lookup table that associates a volume step of the volume knob with a difference between the first perceivable volume level and the second perceivable volume level.
