Title: Testing arrangement for printed circuit boards
IPC: G01R1/073
Filed: 1981-05-22
Abstract: A mechanical jigging arrangement for bringing and holding a circuit board to be tested in registered contact with electrical connections which pass signals to and from an automatic system comprises a contact pin carrying plate P with four depending pillars BC, one at each corner, passing through brackets BD and each having a compression spring BE retained by a washer BH. Two cams R are provided on a rotatable shaft, each cam acting on a median point of the plate through a bearing plate Q. When the cams are rotated plate P is raised with parallel motion with respect to a printed circuit board carrying plate K. Spring loaded contact pins on plate P move through aligned apertures in plate K to contact the circuit board (not shown). Springs BE are such that their total force is much greater than the force of the total number of contact pins. <IMAGE>

Patent GB-2084767-A (GB)
Title: Method and device for feeding loads from a common source
IPC: H02J7/14
Filed: 1981-09-30
Abstract: In a system for feeding loads e.g. vehicle battery and lamps connected to a common voltage source, which have different voltage or current requirements, the arithmetical average value u or peak value and the r.m.s. value U of the supply voltage are regulated differently whilst maintaining the electrical connection between the voltage source and the individual loads. For this purpose, the supply voltage is produced in a pulsed manner, the pulse amplitudes and pulse lengths being regulated individually. An r.m.s. value regulator (1a) determines the magnitude of the output voltage, and an arithmetic average value regulator (1b) determines the relative "on" period of the output voltage. When applied to the electrical system of a motor vehicle fed by a three-phase generator, the r.m.s. value regulator acts upon the field winding of the generator, while the average value regulator triggers thyristors connected to the stator windings with a predetermined frequency and variable duty ratio. <IMAGE>

Title: Improvements in circuit arrangements for modifying dynamic range
Inventor: DOLBY RAY MILTON
IPC: H03G7/00
Filed: 1981-12-09
Abstract: An arrangement for modifying the dynamic range of an input signal has two series connected bi-linear stages with at least one cross connection feeding a signal component from one stage to the other stage to modify the action of the latter. In one embodiment a compressor has two bilinear stages 280 and 282, each with a linear main circuit path including an adding circuit (+) and a further path N1, N2 with non-linear characteristics providing a limited signal to the corresponding adding circuit, and a coupling circuit with transfer characteristic f(s) is connected to the output of the first further path N1 and injects a signal into the second further path N2 in order to improve such factors as reduction in noise modulation. A complementary arrangement applies to the expander 284, 286. In an alternative arrangement, the coupling circuit is a common control circuit for the series- connected compressor or expander stages, which reduces circuit complexity. <IMAGE>

Title: Improvements in fluid flow regulators
Inventor: HARRISON ANTHONY WILLIAM
IPC: G05D7/01
Filed: 1982-01-13
Abstract: A fluid flow regulator for use in a vehicle hydraulic suspension system has a constant restriction (5) connected in series with a variable restriction (9) defined between two relatively movable members (2, 3). Fluid flow through the regulator produces a pressure differential across the constant restriction (5) which controls relative movement of the members (2, 3) to determine the size of the variable restriction (9) such that an increase in the pressure differential causes a reduction in the size of the variable restriction (9). Resilient means (11, 12) is operative to bias a movable one (3) of the relatively movable members (2, 3) against the action of the pressure differential across the constant restriction (5) for each direction of fluid flow through the regulator, so that for each direction of fluid flow, relative movement of the relatively movable members (2, 3) is controlled such that an increase in the pressure differential causes a reduction in the size of the variable restriction (9). <IMAGE>

Inventor: ELIASSON STIG
IPC: E04F13/12
Filed: 1982-11-19
Abstract: A facade unit of sheet metal intended together with a plurality of identical facade units and attachment devices for the units to constitute a facade lining for buildings. Each facade unit has a substantially plane upper portion (3) intended to be an outer surface, and its lower and, respectively, upper short side is designed for cooperation with an attachment device. One, the first, lateral edge of each facade unit is bent so as to comprise, seen in cross- section, a U-shape where the bottom of the U is in parallel with the upper portion (3). According to the invention, a first leg of the legs (8) of the U is bent inward over the bottom of the U, so that the leg together with the bottom of the U forms a V-shaped portion. The second lateral edge (9) of the facade unit is bent downward entirely or partially inward beneath the upper portion (3) of the facade unit to form, seen in cross-section, an S- shaped portion, where the outer free portion of the S is bent to be substantially in parallel with the upper portion (3). The free portion of the S, in cross-section, has a length, which corresponds to the length of the bottom of the U, whereby after the insertion of a second lateral edge (9) into a first lateral edge (8) of an adjacent facade unit in such a manner, that the end of the free portion (24) of the S is inserted into said V-shaped portion, the free portion of the S is locked against movement perpendicular to and in parallel with the upper portion (3) of an adjacent facade unit. <IMAGE>

Abstract: A fastening device for providing an axial force resistant anchorage to a plain hole in a hard material comprises a tubular metal sleeve 1 which is convoluted around its circumference and which is plastically expanded to fit and grip the hole by the forced passage of a short metal spud of polygonal cross-section or a ball 3 through its central aperture. Figure 3 shows a corrugated sleeve 1 of aluminium or other corrosion resistant metal when used as a replacement cavity wall tie. After the ball 3 has been hammered through it does not matter if it subsequently corrodes away. In another embodiment, a stainless steel sleeve is distended by a number of balls of progressively increasing diameter and may be used as a deeply placed rock anchorage to resist very high tension. The device may be used for anchoring in holes cast in metallic alloys which are too hard to be drilled to tapped. <IMAGE>

Title: Electrical signal mixing apparatus
Inventor: STADIUS JOHN ROBERT
IPC: H04H60/04
Filed: 1984-04-19
Abstract: Electrical signal mixing apparatus for recording studios or for live performances comprises a plurality of input channels (12) having means (96, 97, 98, 99) for conditioning input signals applied thereto, a plurality of sub-group channels (10) to which the signals from input channels (12) can be selectively assigned, and a pair of output channels (17) which may receive signals directly from the input channels (12) or via the sub-group channels (10). Routing interconnections between the input (12), sub-group (10) and output (17) channels are controlled by a microprocessor in dependence on operator selections effected via a single manually operable switch control (15, 18) on each channel. The microprocessor detects destination assignments indicated by operation of the switch (18) on a sub-group (10) or output (17) channel, and acts to complete analogue interconnections between input channels (12) and the identified sub-group (10) or output (17) channels upon subsequent actuation of the input channel selector switches (15). The microprocessor control of routing assignments also allows other functions to be performed, such as storage and retrieval of sets of routing assignments or patches used previously or set up for subsequent use, indication of current routing assignments, muting of selected channels to allow in place solo review of individual input channel signals and the additional possibility of handshake with an external computer for obtaining a video display of the information. <IMAGE>
