[Class 138 (i).] Bottles 13, Fig. 1, are placed inverted in holders 10 on a rotating table a while continually rotating brushes 12 on fixed spindles clean the outsides of the bottles in known manner. A row of freshly inserted bottles is then sprayed internally by nozzles 31, of ordinary type, with hot water, after which the table rotates one step. According to the invention, a row of brushes 26, Fig. 2, is then raised and introduced into the partially filled bottles, after which the brushes descend. The bottles are then sprayed with lye and travel to the next row of moving brushes. The brushes 26 are mounted on shafts 25, worm driven, and movable vertically by movement of levers 29 engaging rollers 28 on a bar 27. The holders 10 are made of two short claws situated between the brushes 12 leaving as much of the bottles exposed as possible. The claws are carried on pins 11 to prevent one-sided pressure and to allow the bottles to be turned easily during brushing. The table a has on its inner edge an iron ring c, Fig. 3, and on its outer edge a ring d. A toothed rim f is fixed by screws on to the ring c, and a toothed segment g on a shaft h periodically meshes with the rim f. The shaft h carries a worm wheel i, Fig. 1, connecting with a worm m permanently rotated by a pulley k. The ring d, Fig. 5, has a succession of openings n engageable by a bolt o mounted on a sleeve p arranged in an iron band r screwed to a girder q in the machine frame.

Patent GB-372365-A (GB)
Abstract: 372,365. Typewriters &c. BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, Southampton Row, London.-(Assignees of Peirce, J. R. ; 33, Riverside Drive, New York, U.S.A.) Feb. 6, 1931, No. 3785. Convention date, Feb. 7, 1930. [Class 100 (iv).] Type-bar machines hammer-impression arrangements.-In a record-card controlled statistical machine the type-bars 117, as shown in the Figure, have each two zero type 118, coact with platen 116, and rise synchronously with the card feed, each bar being arrested by a pawl 141 when a printing-magnet is energized. The upper zero type is normally on the printing line and the bars start to rise just before the " 9 " hole positions on the cards are read. The bars have thus moved ten steps when the " 0 " holes are read and the lower zero type are then at the printing line. If a " 0 " hole is read the lower type is positioned ; for a zero in a total the upper zero is used. To remove each type-bar individually, each member 121 for raising the bar is pivoted to a link 335 which has a lug 336 to engage the bottom of the typebar and a hole to receive a pin 337 on the type-bar. This pin is held in its hole by a blade spring 338 which is pivoted at 341 to the type-bar and engages the end 339 of the link 335 laterally. This blade is normally prevented from turning on its pivot by a pin 340 thereon engaging a hole in the type-bar. Each printing-hammer 119 is rotatable about its pivot shaft 120 by a spring 153 but is normally restrained by a latch 154 pivoted at 320 and having pivoted to it a lever 135. When a type-bar rises, a pin 322 on it permits lever 155 to rock counterclockwise so that its hook 325 engages a bar 156 which is oscillated about pivot 157 by cams on the printing-shaft to remove the latches 154. As each bar 117 reaches its upper position the pin 322 rocks a bell crank 323 to depress a lug 324 thereon so that lever 155 is rocked clockwise and unhooked from bar 156. Each hammer may be locked by lever 332, spring 333, and shoulder 334 on the hammer. Each latch 154, as shown in the Figure, has pivoted to its upper end a lever 326 having a spring blade 330 with a pin coacting with two holes 331 in the latch. Each latch has also an arm 327 turned over to coact with the lever 326 of next higher denomination. With levers 326 in the position shown, when a latch 154 is rocked clockwise by bar 156 its lever 326 engages the arm 327 of next lower denomination, if this latter arm and its latch 154 have not already been rocked by reason of a significant figure in that denomination, thus printing from the top zero of that bar.

Abstract: 1356451 Digital transmission; PSK systems FUJITSU Ltd 10 Aug 1971 [10 Aug 1970] 37585/71 Heading H4P  A receiver for 2 n  poly-phase shifted (PSK) signals phase compares the PSK signal with a reference carrier signal and then frequency doubles both signals n-1 times, with a phase comparison after each doubling, the result of phase comparison providing the original n-bit signal. Instead of the final doubling the PKS signal may be phase compared with two carriers differing in phase. In Fig. 3 the PSK signal and reference carrier signal are initially compared in a phase detector PD9. Thereafter the PSK signal and reference carrier signal are doubled in frequency doublers D1-D3, and D4-D6 and phase compared in phase detectors PD10-PD12. Before comparison the carriers are adjusted in phase at phase shifters PS9-PS12. The phase detectors provide a 1 or a 0 according to the cosine of the phase difference between the PSK signal and reference signal, to provide an n-bit parallel output.

Title: Apparatus and method of manufacturing air springs
IPC: B29D22/02
Filed: 1957-12-03
Abstract: 831,625. Moulding air-springs for vehicles. FIRESTONE TIRE & RUBBER CO. Dec. 3, 1957 [Dec. 6, 1956], No. 37616/57. Class 87(2). [Also in Group XXXII] An air spring (see Group XXXII) for a wheel suspension system is moulded and vulcanised by taking a blank built up on a drum from plies 22, 23 of rubberised fabric having an interior lining of Neoprene and slipping it over the head 57 of a pneumatic plunger 50 together with a flanged cup 33 which forms part of the finished spring. The ram of the press is then lowered and the end of a boss 55 contacts a bead 24 of the blank and the cup 33 and clamps them together against the head of the plunger to form a fluid tight seal. As the ram continues to descend, it forces the plunger 50 downwardly against resistance from the pneumatic cylinder 61. Shortly after the bead 24 is clamped, continued lowering of the ram causes the large bead 25 to be engaged in the groove 62 in the base section 48 and immediately after that, the intermediate section 47 engages the bead to clamp it and produce a fluid tight seal. Air or steam under pressure is then introduced through a pipe 76 to the interior of the blank. As the mould continues to close, the bead 24 is forced by the boss 55 through the large bead 25. When the mould is fully closed, the blank takes up the position shown in Fig. 7. After vulcanisation is complete, the press is opened, but the plunger 50 is retained in its lowered position, the spring being stripped from the mould sections and remaining on the boss of the top mould section. When the mould is completely opened, the spring is removed by a slight tug. Alternatively, air under pressure can be introduced through a passage 77 in the top mould section to blow the spring off the mould. The mould sections may be steam heated. It is stated that by moulding the spring in this telescoped shape, the wall of the spring is normally under tension, which prevents wrinkling and premature failure of the spring in use.
