Title: Improvements in or relating to pressure reducing valves
IPC: G05D16/06
Filed: 1936-06-16
Abstract: 476,184. Pressure-regulating valves. SWAN, A., and CLOTHIER, W. C. June 16, 1936, No. 16720. [Class 135] A pressure-regulating valve has a balanced closure comprising a sliding member co-operating with one or more fixed ports and a single positive ,seating valve member in series with the balanced valve member and on the delivery side thereof and arranged to close after the balanced valve. In the form shown in the Figure, the balanced valve comprises a tubular piston 5 provided with a balancing port 20 and slidably mounted in a ported member 6. The positive closure comprises a lift valve member 10 formed with a socket slidably mounted over a pin 9 on the piston valve. A projection on the valve 10 is normally held in contact with a stud 14 secured to the spring-loaded actuating diaphragm 1 subject to outlet pressure, by a spring 8 housed within the piston valve member. The two valve members are pressed apart by a spring 15 so that in the event of the piston valve sticking the two valves may separate to allow the lift valve member to close. The loading spring 3 may be made adjustable and the piston valve may be replaced by a sliding or rotary valve. The two valve members may be rigidly secured to each other and to the diaphragm. The upper side of the diaphragm may be acted on by a second controlling pressure.

Abstract: 348,414. Television. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. May 30, 1930, No. 16802. Convention date, June 8, 1929. [Class 40 (iii).] In a system in which the scanning at the transmitting or receiving station is effected by a " Weiller " mirror-wheel in conjunction with two or more light sources so arranged that they scan different parts of the object, the light beams are brought into operation cyclically after each complete revolution of the mirror wheel so that the complete scanning of the picture is effected in a number of revolutions equal to the number of the light sources. The received signals are applied to Kerr cells K1, K2, operating in conjunction with a constant light source B, during successive rotation of the mirrorwheel S. The change-over is effected by a rotating switch U suitably geared to the mirror-wheel S. The light-sources L1, L2 (Fig. 2) may be arranged so that the points l1, l2 scan adjacent areas I, II of a picture surface P. Alternatively, Fig. 3 (not shown) the points l1, l2 may describe alternate lines on the picture area. The Kerr cells or glow lamps may be formed by a number of electrodes or cathodes respectively in a single cell construction or gas chamber. The Specification as open to inspection under Sect. 91 (3) (a) states that the light beams may simultaneously scan different parts of the picture surface. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to automatic screw drivers
Filed: 1941-12-31
Abstract: 548,655. Screwing-up screws. KODAK, Ltd. Dec. 31, 1941, No. 16842. Convention date, May 15. Addition to 543,497. [Class 83 (iii)] The screw driver for inserting screw-sticks according to the parent Specification is arranged for power operation. It is fitted with a belt pulley 14 and is mounted on roller bearings 13 in a tubular handle 12 secured to a frame 11 on which is mounted a motor 22. The bearings 13 permit sufficient play so that, on pressure being applied to the screw T after location in the hole, a spring 25 is flexed to close a switch 29 and start the motor. The machine may be suspended by springs 37 from a support 32 but may be carried by a track or rail. When the screw twists off, release of pressure on the handle permits the springs 37 to lift the machine whereupon the weight of the screwdriver 2 assists the spring 25 to open the switch and stop the machine. The supporting rail may be such as to facilitate the successive fitting of screws to a series of holes for example at the four corners of an article. After twisting-off takes place the severed parts may be maintained under pressure to burnish off the break.

Abstract: 1469343 Apparatus for overlapping or folding bag inserts WINDMOLLER & HOLSCHER 19 April 1974 [9 May 1973] 17311/74 Heading B5D [Also in Division B8] An apparatus for laying a film web in Z- shaped folds or for overlapping separate portions of film web or for folding over the ends of separate portions of film web comprises a reciprocable folding blade 12 for engaging the web which is held on a first conveyer 1 by suction, a static charge or an adhesive coating, and introducing it into the nip 19 of a second conveyer 2 which is slower than the first conveyer 1. The first conveyer 1 may comprise a plurality of spaced and perforated belts 3 which pass over bars 6 having slits 18 through which suction is applied. The folding blade 12 is a comb-like structure, the tines of which pass between the belts 3. The guide roller 4 of the first conveyer 1 has suction nozzles over its periphery or cooperates with a guide belt 17 or roller, Fig. 1 (not shown). Air from nozzles 14 can blow the leading ends of separate web portions into the nip 19. To produce Z-shaped folds in a web, Figs. 1 and 2 (not shown), the folding blade 12 pushes the upper end of a loop of web which is formed between the first and second conveyers 1 and 2 and has one limb held on the first conveyer 1, into the nip 19. To overlap separate web portion ES, the leading end of one web portion ES is introduced into the nip 19 by the folding blade 12 and/or a blast of air from the nozzles 14 while the trailing end of the preceding web portion is still held on the first conveyer 1. The web or web portions are laid on a paper web 10 by the second conveyer 2.

Title: Improvements in and relating to folding and/or stacking machines for flexible articles such as sheets and the like
IPC: B65H45/101
Filed: 1944-09-12
Abstract: 603,710. Fabric folding and stacking machines. PRESTON, J. E. Sept. 12, 1944, No. 17398. [Class 42(ii)] [Also in Groups XVI, XXIV and XXXV] In a machine for folding and/or stacking flexible flat articles, e.g. bed sheets, wherein the articles are fed into the path of a reciprocatable folding blade, two independent electrical trip circuits are controlled by the articles to be folded, one to cause actuation of the folding blade in one direction and the other to cause actuation in the opposite direction. The articles are passed into the machine on belts 12, Fig. 1, which may be common to an ironing machine and the folding and/or stacking machine and may constitute the driving elements for the latter. An article, on leaving the belts at a roller 16, drapes behind a folding blade 30 on arms 36, Fig. 3, until almost a quarter of the article has approached the blade 30, whereupon the blade is moved back to hold the leading portion of the article against a stop 99 with the quarter fold-line across the front edge 31 of the blade. The remainder of the article, which continues to be fed, drapes in front of the blade 30 until the threequarter fold-line approaches, the blade is then moved forward to press the article between folding rollers 32, 33 which deliver it from the machine. The arms 36 are reciprocated at the required periods by a cam 40 working in conjunction with a spring 44, Fig. 3. The cam 40 is brought into operation by a pawl and ratchet wheel arrangement, (see Group XXIV), actuated by magnets 52, 52a, energized at intervals by trip circuits (see Group XXXV), which include timing devices adapted to be set to cause folds at desired positions along the articles, e.g. at quarter, half and three-quarter positions. The lengths of the articles may vary within a predetermined maximum and minimum. When the invention is applied to a stacking machine, the horizontal blade 30 is replaced by a vertical blade 30a, Fig. 8, and the rollers 32, 33, shown in Figs. 1 and 3, are dispensed with, the articles being stacked by folding over the vertical blade in the manner shown in Fig. 11. In another modification, the arms 36 may be provided with a blade adjustable into either horizontal or vertical positions and the folding rollers may be arranged to be swung out of operative position to enable the same machine to be used for either folding or stacking. Specification 591,000 is referred to with regard to the electrical trip circuits.

The temperature of the oil is measured by a thermocouple 5. Heating may be effected either while the oil is flowing through the chamber or with it stationary in the chamber. The gauge 6 is such as to indicate any abnormal increase in pressure such as a pressure drop meter. In another embodiment Fig. 2 (not shown) the oil is pumped into the chamber 11 and pumping is stopped if the pressure increases to a predetermined amount at pressure gauges 17, 18.
