IPC: F16D65/42
Abstract: 756,206. Linkwork. HUGHES, J. March 16. 1955 [March 17, 1954], No. 7713/54. Class 80(3) [Also in Group XXXIV] In an automatically-adjustable stop device, shown applied to vehicle braking mechanism, the return movement of the brake shoes is limited by a frictionallyheld stop pin 6 which is automatically advanced along opposed slots 14 in the base and cover (not shown). of a box 12 fixed relatively to the brake drum, in order to compensate for wear of the brake linings. The pin 6 is supported by pivoted levers 5, 5a which are splayed apart by a spring loaded button 4 to press pivoted friction blocks 8, 8a against converging side walls of the box 12 and thus prevent movement of the pin 6 towards the right. A rod 1 connected to the brake shoes, which are actuated by means not shown, has a lost motion connection with the pin 6, the amount of lost motion being adjusted by a screw actuating a block slidable in the eye of the rod 1 to give the required clearance between the brake linings and drum. Should the linings become worn so that application of the brake causes the rod 1 to exceed the predetermined lost motion, the pin 6 and blocks 8 are shifted to the left to take up a new stop position limiting the return of the rod 1 and thus restoring the original clearance between the brake linings and drum. The box 12 may be replaced by a tapered-bore cylinder. Levers 10 pivoted to the blocks 8. 8a are connected to a slidable pivot pin 11 actuation of which shifts the blocks to the right to reset the device It is stated that a feeler rod contacting the face of the brake drum may be connected to the pin 11 so that should the drum overheat and expand, causing the device to overcompensate, subsequent cooling of the drum shifts the pin 11 to the right to return the device and thus avoid binding of the brakes.

The only connection between the joist support and the masonry is between adjacent courses of masonry and hence the support can be positioned anywhere along a wall structure for the optimum spacing of joists, without the cutting of bricks or blocks forming the masonry. The broadest part of the base coincides with the position of maximum loading, along the line 17 coinciding with the face of the wall. The joist support base is stiffened by a tapering rib 28. A tongue 23 is pressed out of the base to form a stop 29 which abuts against the masonry. The apex 30 us turned down and with the hole 24 forms a key for mortar. Nail holes 21 are provided in the wings 19, 20. <IMAGE>
Patent GB-2010550-A (GB)
Title: Random access storage device with a movable recording medium
IPC: G11B27/30
Filed: 1978-12-01
Abstract: In a storage apparatus wherein signals recorded on tracks assigned addresses in advance on a rotary recording medium such as an optical video disk are randomly searched at high speed, a random access storage apparatus is provided in which erroneous searches attributed to a transient phenomenon due to a jump for the search, a drop-out, etc. are prevented. The storage apparatus includes an error check circuit. In a random access operation, a read head is mechanically moved to the vicinity of a target address, whereupon an address signal of a track to which the head has been moved is read. Whether or not the address signal is normal is determined by the error check circuit. If the address signal is determined to be normal, it is stored in a register as a reference address. A light spot is deflected by the number of tracks which corresponds to the address difference between the reference address of the register and the target address. If the address signal is determined to be abnormal, the light spot is unconditionally deflected onto the adjacent track and an address signal is read out at the new position of deflection. Thereafter, the error decision and the subsequent operation described above are carried out.

Title: Digital processor for processing analog signals
IPC: H03H17/02
Filed: 1979-04-12
Abstract: A digital processor for real time processing of analog signals is described. The processor duplicates filters, waveform generators and non- linear functions, such as rectification, with a high degree of stability and at a relatively low cost. A two-port, random-access memory 16 provides inputs to an arithmetic logic unit (ALU) 10. One of these inputs is coupled through a scaler (shifter) 14. The scaler in conjunction with the ALU provides efficient multiplication, particularly by coefficients. ALU overflows are handled in an unusual manner to eliminate additional processing time for overflows. In a typical application, the processor, which is formed on a single semiconductor chip, with its 192- word program, samples an input analog signal at the rate of 13,020 Hz and detects 8 tones in the signal. <IMAGE>

Title: Rapid response distillation method and apparatus for use therein
IPC: B01D3/32
Filed: 1979-05-11
Abstract: Stable equilibrium conditions are obtained in a distillation column, whether used for stripping section analysis or enriching section analysis when the distillation column 1 mounts a reboiler 4 and provision is made for an upper region 19 of the column to have cooling means 18 for effecting condensation of volatile material which and, is returned to the reboiler through a return pipe system 21, 22. For stripping section analysis, the reboiler communicates with an upper region of the distillation column 1 through a pipe 11. Liquid from the reboiler is raised to the required feed level to the distillation column and in so being raised is heated. The distillation column thus undergoes inversion of the functioning it would exhibit as a normal distillation column. In enriching state analysis liquid from the reboiler is heated as it passes through a circulation loop 7 and then passes back through the reboiler, up the distillation column which is employed as a normal distillation column, with volatile material being condensed and returned to the reboiler externally of the column. <IMAGE>

Title: Aperture system for multi-source tomography and a multi-source tomography arrangement including said aperture system
IPC: G21K1/04
Filed: 1979-10-25
Abstract: In a multi-source multi- perspective tomography arrangement, a group of sources 1, 2 and 3 located in a plane E are flashed simultaneously to generate beams 10, 11, 12 limited by apertures in a diaphragm so as to overlap at an examination region 15 in a body 14 under examination. A multiperspective radiograph 17 is thereby formed from which a sectional image lying e.g. in the plane 13 can be synthesised e.g. by multiple overlapping projection. Hitherto, to vary the size of the irradiated region 15, a diaphragm with several sets of distributed apertures was required. The improvement comprises an aperture system B formed by two adjacent diaphragm plates B1 and B2 having therein respective corresponding apertures 7a, 8a, 9a and 7b, 8b, 9b which mutually overlap to form effective beam limitation apertures, and means V for displacing the plates B1, B2 relative to one another to vary the size of the beam limitation apertures. Several groups of sources in respective planes can each be limited by a corresponding pair of diaphragm plates provided non-limiting apertures are provided in each diaphragm set for beams relating to other source groups. <IMAGE>

Title: An automatical drain valve, preferably for aerated beverages such as beer
IPC: B67D1/14
Filed: 1980-02-15
Abstract: The drain valve comprises a stationary housing (1) with a tubular portion (7) pivotable by means of a lever, whereby said tubular portion raises together with a bearing (24) and a locking hub (18) by means of a pin (10) controlled in a cam track. By means of balls (17), the locking hub (18) is raised together with a spindle (12) comprising a valve member (13), which is raised from its seat (3). This movement counteracts the effect of a closing spring (15). When a predetermined amount of liquid has passed through a supply pipe (5), a flowmeter transmits an electrical pulse to a magnet coil (22) raising the locking hub (18) by means of a drawbar (19). Thereby the balls (17) are be pressed out of a groove (16) in the spindle (12), whereby the spring (15) presses the valve member (13) towards the seat (3) and thereby close the valve. When the lever (8) is returned to the starting position, a compression spring (23) represses the locking hub (18) downwards into the position in which the balls (17) are retained in the groove (16). <IMAGE>
