Title: Data-transmission error-detecting arrangement
IPC: H04L1/00
Filed: 1962-02-02
Abstract: 945,916. Code telegraphy. STANDARD TELEPHONES & CABLES Ltd. Feb. 2, 1962 [Feb. 8, 1961], No. 4104/62. Heading H4P. [Also in Division G4] In a data transmission system, e.g. a telegraph system, a block of data bits is applied serially over line 4 to an output terminal 3, to scale-of-two counter Zx, and through gates G1-G4 to scale-of-two counters Z1-Z4. Clock pulses occurring at the same rate as the data bits are supplied from terminal 1 to a multistage binary counter T1-T4. A count is thus made by Zx of all the " 1's " in the block, Z1 counts the " 1's " occurring in alternate bit positions, Z2 counts the " 1's " occurring in alternate groups of two bit positions, and so on. The check bits obtained by sequentially scanning Z1-Zx are applied to output terminal 3. An additional check bit for the check bits may be generated by a counter Zz. Up to seven consecutive errors may be detected by generating a further check bit from a counter C supplied with every fourth bit. Up to 15 consecutive errors may be detected by generating yet another check bit from counter stages arranged to count every eighth bit. The calculation of the check bits is performed at the transmitting and receiving stations and the check bits may be sent from either station to the other for comparison and initiation of repetition of the block when errors are detected.

Title: Process and means for performing electrostatic paint spraying
IPC: B05D1/00
Filed: 1956-02-09
Abstract: <PICT:0792607/III/1> A process for electrostatic paint spraying comprises maintaining the paint in continuous circulation, e.g. by a pump, and feeding the paint to a nozzle 3 having a narrow elongated gap 10 through which the paint issues under the influence of an electrostatic field, e.g. the nozzle 3 may be connected to the positive of a highvoltage source, an article to be coated being earthed through a conveyer.  The nozzle 3 comprises coaxial tubes 4, 11, each having a longitudinal gap bordered by upstanding walls, the gap 10 in the tube 4 being narrow enough to exert a capillary action on the paint.  Paint is delivered to the tube 4, excess paint emerging from the gap 10 passing through a gap 10a between adjacent walls to the tube 11 from which it returns to a reservoir to be recirculated.

Title: Improvements in equipoising mechanism
IPC: F21V21/26
Filed: 1934-02-10
Abstract: 433,617. Equipoising-mechanism. CARWARDINE, G., 17, Macaulay Buildings, Bath. Feb. 10, 1934, Nos. 4440 and 7197. [Class 52 (v)] [See also Groups XI, XXX, and XXXII] An equipoising device comprises a parallelogram linkage or equivalent mechanism having one of its sides or members extended to form a lever 5 carrying the object to be counterpoised, e.g. a lamp 7, the parallelogram being pivoted at or near a joint 2 on its opposite side so as to be free to turn as a whole about a horizontal axis, the parts being equiposed by two forces at least one of which is provided by overwound springs. A supporting lever 1 is pivoted on a horizontal spindle 2 extending between the two prongs 3 of a forked member freely mounted on a vertical spindle 4 fixed to a heavy base. The lever 5 carrying the lamp 7 is pivoted at 6 to the end of the lever 1 and joined by a link 13 to two short arms 12 pivoted on the spindle 2, the parts forming a parallelogram linkage. A spring 10 extending between the end of the lever 1 remote from the pivot 6 and a rod 11 fixed between the prongs 3 counterbalances the moment of the parts about the pivot 2, while two springs 16 extending between the rod 11 and a spindle 14 connecting the link 13 to the arms 12 counterbalance the moment of the lever 5 and lamp 7 about the pivot 6. The springs are so wound that the force exerted by them is proportional to their lengths, as de. scribed in Specification 404,615, and their tension may be adjusted by altering the position of the rod 11 in a series of holes 17 in the prongs 3 or by screw adjustments. The lamp is frictionally pivoted in a fork 8 on an axis 9 passing through its centre of gravity, and the fork 8 may be turned about the axis of the lever 5. The lever 5 and link 13 may be tubes of square section for the passage of the leads 18. The device may be supported from a ceiling the levers 1, 5 being then arranged as second-order levers. The lever 1 may comprise two flat strips separately pivoted to the prongs 3 and spaced by rods, the arm 12 being pivoted between the parts 1, 13 at a distance from the pivot 2. The axis of the lamp 7 may be maintained vertical in all positions of the levers by a cord fixed to a pulley rigid with the lamp, passing over a pulley at 6 and attached to a third pulley rigid with the prongs 3. Instead of a parallelogram linkage an endless cord passing over pulleys rigidly fixed to the levers 5, 12 at their axes 6, 2 may be used to maintain these levers in parallelism. The lever 1 may be tubular and house the spring 10 which is then connected to the rod 11 by a cable passing over a pulley at the end of the lever 1, the spring then being made to exert a force proportional to the distance between the pulley and the point where the cable is anchored to the support.

Title: Method and apparatus for classifying solids suspended in a liquid
IPC: B03B5/62
Filed: 1943-03-19
Abstract: 603,215. Washing granular substances. McNEILL, H. L. March 19,1943, No. 4501. [Class 82(ii)] Solids suspended in a liquid are classified by directing the feed into such a liquid body in a substantially horizontal stream confined at the surface in a zone extending from one side of the body directly across to another side, restricting the stream at its lower portion to a greater degree than that at the surface to obtain a classifying effect, subjecting the matter in the classifying zone to hindered settling by introducing a fluid in an elevating stream into it, discharging the settled solids from the lower portion of the stream, maintaining the finished. product at the surface of the horizontal stream by its movement at a relatively greater velocity and discharging tha latter product at the completion of its movement in the said stream. The feed is fed by a launder 13 in the first compartment 21 of a tank 7 in a horizontal stream which passes over into the second compartment 19 of the tank provided with an overflow 23. The heaviest material settling in the tank 21 is removed by a spiral 22 and the material passing into the compartment 19 is subjected to hindered settling in cones provided with spigots 18 into each of which enters a conduit 16 extending from a funnel 17 into which small quantities of water are supplied continuously. Solids settling in the cones descend through the spigots 18 into the tank and are removed by a spiral 20, the fines passing over the weir 23. In another form of apparatus, Fig. 3, the compartment 21 is provided with cones 10a into which enter conduits 25 connected with a source of liquid or gas, the heavier material descending therein being removed by a reciprocating rake 24. The lighter material passes over into the compartment 19 where it is treated in the cones provided with spigots 18, the heavier material settling in the tank being removed by a rake 24 and the lighter material passing over the weir 23. To assist the elevating tendency of the counter-current flow, a reciprocating diaphragm 26 is provided in the wall of the tank 7 and is actuated by a prime mover 27, e.g. an eccentric.

[Also in Division F1] In a carburetter, in which the cross-sectional area of a flexibly mounted fuel metering jet is controlled by a contoured needle in dependence on the position of a suction operated piston which controls the effective cross-sectional area of a choke in the main air passage, vibration damping means minimize vertical vibration of the fuel metering jet relative to its sliding bearing. The vibration damper comprises a tubular metal member 23, Fig. 1, split axially to form two halves which embrace a ferrule 24 on a jet head 21 and are held in frictional engagement with the ferrule by a spring clip. The fuel metering mounting is a temperature sensitive bimetallic strip 15 which is attached to the jet head 21 by a joint which allows free angular movement with zero backlash. In a modification two or more bimetallic strips constitute the flexible mounting means.
