Abstract: An office space dividing system which includes rectangular post-supported panels having central cores and upper wire troughs. Each panel includes two stiles and upper and lower rails constructed of tubular metallic members having the same substantially rectangular cross-sectional configuration which includes a longitudinal channel. The stiles and rails are arranged to define four corners each having two adjacent unobstructed openings. A right angle reinforcing member is press fit into the adjoining openings to provide four square corners which are maintained by staking. The stiles and lower rail are oriented such that the longitudinal channels support the central core. The upper rail is inverted, with the longitudinal channel supporting the wire trough. A spanner extends across each post, between adjacent panels, from wire trough to wire trough. Post caps, panel caps, and four plastic corners on each panel complete the system.

Abstract: A theater chair of the rocking type having a standard on each side for supporting the chair. A contoured spring guide is attached to each standard and provides a support and deflection profile for leaf springs held in trolleys on each side of the chair. A wing plate extends upwardly from each trolley and terminates in a guide surface. A guide roller is mounted near the top of each standard and provides lateral and longitudinal support for the guide surface the wing plate on each side of the chair. A chair seat is mounted on each trolley and a chair back is mounted between each wing plate. The chair seat and chair back move in unison in a rocking manner as the leaf springs increase and decrease contact along the surface of each spring guide.

Abstract: A space dividing system which includes vertically disposed posts and space dividing panels. Each post includes a center core and a plurality of circumferentially spaced, longitudinally extending T-shaped members having a stem or leg portion integrally joined to the core, and a flange spaced outwardly from the core. The space between the core and inner surfaces of the flanges defines vertical wire ways. Each space dividing panel has upper and lower hook-like connector assemblies fixed to its vertical edges. The T-shaped members have predetermined portions of their associated flanges removed to define access openings having flange-defined support edges for supporting the upper and lower hook-like connector assemblies. Flanges of T-shaped members not associated with a space dividing panel are concealed by one or more post covers having retaining beds which removably engage lateral edges of predetermined flanges.

Abstract: The double action latch employs a strike with two latches and a stop on the opposite side of the latches. The handle actuates a pivotally mounted bracket unit to cause a roller to ride over the first latch while moving a plate into a plate into engagement with the stop. This brings the door into a partially opened position, for example, for venting an oven. The handle is returned to the upright position and then a second pull is effected to move the roller over the second latch so as to permit the door to be fully opened.

Abstract: A modular barrier comprising a pair of vertical posts, a pair of parallel rails and a holding assembly for retaining the ends of the rails inside the posts. Each of the posts has a facing vertical wall with the vertical wall having an upper window and a lower window. An upper tongue extends upwardly into the upper window while a dependent lower tongue extends into the lower window. Each of the rails has a first end disposed inside one of the posts and a second end disposed inside the other post. The posts have facing inside walls and each of the walls has an indentation adjacent the rails receiving a corresponding one of the tongues. The holding assembly is positioned entirely within a post and functions to push the rails towards each other so that the tongues are held in their corresponding indentations to maintain the posts and rails assembled.

Abstract: Seating for a telescoping row system or the like is mounted to a beam pivotally secured to a base anchored to the platform and riser. The beam is raised arcuately into a use position by a pneumatic bellows and is mechanically locked in the upright position to permit deenergization of the bellows. Reinflation of the bellows disengages the lock and the assembly collapses slowly against the controlled deflation of the bellows.The seat is positionable on the beam initially without fasteners to facilitate installation. In similar fashion, armrests are secured to the beam separate from the seat and adjustable along the beam to permit overall width variations.

Abstract: A connector assembly for joining a horizontal member and a vertical member without the formation of substantial exposed gaps. The assembly includes a base with a saddle surface at one end and an abutment flange at the other end. The base has an aperture between the ends and a slot communicating with the aperture. A locking collar has a bore receiving the base and an inwardly directed annular lip at a first end of the collar. The collar also includes an internal screw thread and an abutment for engaging the flange of the base. Also the assembly includes a locking insert with a body for reception in the base. The insert has extending arms at one end terminating in screw threads and at the other end a holding flange for retaining the horizontal member. A method of using the connector assembly is also disclosed.

Abstract: A peripheral processor for a central processing unit is in the form of a memory which is repetitively loaded with data scanning an array. The processor performs predefined logical operations between respective elements of successive scans of data. Preferably address signals sent to the peripheral processor via a preassigned set of address lines specify a desired one of a plurality of predetermined logical operations. Logical operations may also be performed when data is written to processor memory as well as read from the processor. A memory shift register, for example, automatically transfers original data from present scan memory to past scan memory when new data is loaded into present scan memory.

Abstract: The present invention comprises a mounting mechanism for releasably mounting a drawer unit under a work surface, wherein the drawer unit comprises a drawer enclosed in a drawer casing. The mounting mechanism comprises an elongated mounting bracket that is mounted transversely on the underside of the work surface. A mating upper drawer casing flange on the drawer casing faces the mounting bracket flange and fits over the mounting bracket flange when the drawer casing is mounted. A releasable retaining means holds the drawer casing flange in overlapping relationship with the mounting bracket flange. Additional drawer units may be releasably mountable on the underside of each drawer unit immediately above it.

Abstract: A circuit breaker characterized by a housing and a circuit breaker structure within the housing and comprising an electromagnetic trip including a magnetic yoke and armature and means associated with the armature for adjusting the electromagnetic force required to pull the armature to the yoke, whereby changing of the force requirement results in significant reduction in operating time of the trip unit.

Abstract: A clocked digital Boolean processor which responds to operation code signals and to successive single bit input (operand) signals to drive a single bit accumulator to output the successive answers of chained Boolean operations. The hardware elements are configured such that no feedback of the accumulator output (the previous answer) is required because the logic circuits determine the setting or resetting of the accumulator regardless of what the previous answer was--and yet such that the new answer represents the result of a LOAD, AND, OR or EX-OR operation performed as if the input operand and the previous answer were taken as two operands.

Abstract: A system for transmitting binary instruction or data words to or from a computer by control from a home base remote from the computer site, and characterized by the entry of signals into the computer or the extraction of signals from the computer performed by apparatus which directly connects to the computer console manual switches and indicator lights. A single telephone line forming two simultaneously active channels transmitting time-spaced pulses in opposite directions, by modems known in the art, is used as the communication link. A special purpose microcomputer directly connected to the main computer console acts figuratively to actuate the console push buttom switches in response to pulse train signals received from home base and representing single bits or multibit words. It returns to the home base a rapidly iterated and updated pulse train representative of the status of all console lights.

Abstract: A digital computer of relatively simple and efficient structural organization which is capable not only of conventional arithmetic operations according to a program but also of (i) performing chained Boolean logic processing on any selected bit of any of various selected words held in memory, (ii) using the logic processing result by storing it at any selected bit location in any of various selected words held in memory, and/or (iii) causing different, predetermined instructions within a program to have their execution dependent upon the results of previously performed single bit logic processing. The logic processing is carried out in response to specially coded instruction words which may be randomly interspersed between conventional arithmetic instruction steps within an overall program.

Abstract: An electromagnetic contactor characterized by a stationary contact structure, a movable contact structure, the movable contact structure comprising a contact arm and a conductor, and a shuntless, pivotal electrical connection between the contact arm and the conductor.

Abstract: An improved final servo control for numerical control systems of the type which perform linear and/or circular interpolation by iterative updating of commanded position signals. The improvements are embodied in means to sense when the servo loop has had an offset error introduced by drift or aging of the final amplifier or similar components, together with means for progressively and automatically removing such error; and by means to avoid attempts at extreme acceleration or deceleration beyond the ability of the servo power element (motor) to accomplish, --by creating from an iteratively updated primary position command signal, whose rate of change may suddenly alter by a wide margin, a secondary position command signal which varies ultimately by the same amount but at a lesser rate of change.
