Abstract: 1,065,250. Pressure relieving devices. OLAER PATENT CO. June 24, 1964 [July 4, 1963], No. 26179/64. Heading F2V. [Also in Division F1] The oil chamber (24), Fig. 5 (not shown), of an hydraulic accumulator comprising a flexible diaphragm (17) distended within a casing (10) by compressed air has two independent unrestricted passages (26, 27) leading therefrom serving as oil inlet and outlet respectively whereby eddies are reduced during such periods as oil both enters and leaves the chamber (24). Inlet passage (26) connected to an hydraulic installation (45) opens into the central portion of a strainer (35) whilst outlet passage (27) connects the periphery of the strainer via a duct (29) to the inlet of a pump (46).

Abstract: 673,116. Conveyers. SIMPLEX WRAPPING MACHINE CO. Oct. 12, 1949; [Oct. 19, 1948] No. 26221/49. Class 78 (i). [Also in Group XVII] In a packeting-machine (see Group XVII), flat bags are fed by rollers 43, 44, Figs. 2 and 5, between a series of belts 48, 50, which are made of rubber or wire springs and are engaged in grooves in the rollers 43 and 44 and further rollers 51 and 52, the runs of the belts being staggered, as shown in Fig. 6A, so that each bag is caused to assume a corrugated form. The rollers 51, 52 are associated with stripper fingers 76, 77 whereby the bag, which is bent through a right angle as it passes through the rollers, is discharged between guide plates 81, 82 and falls between further guide plates 153, 154 on to a verticallyadjustable table 86, Figs. 2, 5 and 30, extending horizontally along the front of the machine. The bag is then moved along the table to filling and closing stations by a step-by-step conveyer which comprises a series of transverselymovable bag-engaging elements, including pairs of verticallyspaced fingers 91 and 92 and elements 93-96, carried by units 97-102 each comprising a housing 104 mounted by rollers 105, 107 and 109 for longitudinal movement on guide rails 106 and 108. Each element or pair of fingers is carried by a member 116, Fig. 5, which is secured to a pair of racks 110, 111 meshing with pinions 112, 113, each pinion 113 being mounted on a horizontal shaft 114 which is simultaneously reciprocated and rotated in opposite directions by cam mechanism and rack and pinion gearing to cause the bag-engaging elements to move in rectangular paths. The units are also fitted with brackets 151, 159, 162, 164, 165 and 166 respectively, supporting guide plates 152, 161, 163, 167, 168 and 169.

Title: Improvements in prepayment mechanism
IPC: G07F15/12
Filed: 1921-10-05
Abstract: 191,145. Adnitt, W. D. Oct. 5, 1921. Clockwork-actuated valves - A prepayment mechanism for delivering gas or electricity for a predetermined period of time comprises an automatic gravity-actuated cut-off controlled by clockwork and a hand cut-off which zeroizes the whole apparatus so that no unconsumed supply remains. After prepayment a bell-crank lever 16 having a forked end embracing a roller 17 on the cut-off mechanism is rotated to raise the cut-off mechanism which slides on a vertical guide rod 18 and a pivoted rack 19. A wheel 21 of a clockwork carried by the cut-off engages the rack and allows the mechanism to descend slowly to stop the supply after a predetermined time, the clockwork being started by a wire 33 on a pivoted arm 34 actuated by an arm 37. To extinguish the gas or electricity before the normal time, a handle 9 is actuated. This causes a pin working in a slot in the bottom of the rack and controlled by a spring 24 to move the rack out of mesh with the wheel 21 allowing the cut-off to fall and operate instantaneously. A resilient member is provided on the bottom of the cut-off device. This may comprise a rubber ball or, as shown, a plunger 30 moving in a cylinder 38 and acting as an air dash-pot. The plunger 30 depresses a rubber diaphragm 26 held up by a spring 27 on to the top of a gas inlet pipe 29.

Abstract: 668,719. Die-stocks. LEE, E. L. Oct. 27, 1950, No. 26299/50. Class 83 (iii). A die-stock has a flanged cylindrical guide member 10 which is keyed to the stock and clamped between the die 6 and the stock with its flange 13 resting on the bottom of the diereceiving recess 3. The guide 10 has lands corresponding to the cutting lands 7 of the die and the flange 13 has a pressed-out tongue 14 which engages with a notch 15 in the stock so that the two sets of lands are approximately registered in line. A clamp plate 16 retains the die in place and has a pair of slots 19, 20 engaging bolts 17, 18, the slot 19 being openended to allow the plate to be swung about the bolt 18. The guide may be provided with clearance in the recess 3, the aperture 4 and the notch 15 so that after adjustment of the die by the screws 9 and consequent movement of the axis of the die relative to the stock, cutting of the work-piece can be begun sufficiently to centre the guide and die relatively to each other, after which the plate 16 can be fully tightened, the die-stock then being set for further operation on similar work-pieces. For fitting the guide to an unmodified normal die-stock, an adaptor 22, Fig. 5, fits in the recess 3 of the stock, where it is secured by the adjusting screws 9, one of which engages a detent recess in a circumferential groove on the smaller diameter part 23 to ensure approximate register of the cutting and guide lands. The adaptor has adjusting screws for the die 6, which is mounted in a recess 24, and has threaded holes 31 for the clamp-plate screws 30 and a land 27 with a projection 28 which engages in a notch in the flange 13 of the guide 10.

Title: Video tape recorders

Filed: 1973-06-05
Abstract: 1429558 Video tape recorders; control circuits MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 5 June 1973 [5 June 1972] 26888/73 Heading G5R A-video tape recorder includes a control circuit for a capstan motor which ensures that the capstan is driven only when the head drum has attained a predetermined speed, to permit an air bearing to form between tape and drum. The head drum motor is a brushless D.C. motor having pick-up windings 50a-50c in the same core slots as the main windings, the output from the pick-up windings being rectified 52 and smoothed 54, and fed to a differential amplifier 56 where it is compared with a reference voltage, applied to the base of a transistor Q2. Above a minimum head speed, the output at 58 from the amplifier 56 decreases as the head speed increases (Fig. 3, not shown), and is applied at 62 to a transistor Q5 via an adjustable resistor 64 which is set so that Q5 becomes cut off when the applied voltage falls to a value corresponding to a head speed slightly less than the operative. This renders a transistor Q4 conductive to connect the capstan motor to a power supply 60. The control circuit can alternatively be responsive to the spacing between pulses produced on rotation of the drum. The head drum motor is itself controlled, via a switch closed by the pinch roller as it engages the capstan, from the output of the control circuit of Fig. 2 and from a phase comparator synchronizing head rotation with vertical synchronizing signals recorded or played back.

Title: Improvements relating to substituted iminodibenzyls
Filed: 1955-09-21
Abstract: The invention comprises compounds of the formula: <FORM:0777546/IV(b)/1> Such compounds are obtained by heating a disubstituted 2.21-diaminodibenzyl of the formula: <FORM:0777546/IV(b)/2> or the diphosphate thereof with polyphosphoric acid at 220 DEG  to 300 DEG  C.  Dichloro substituted 2.21 - diamino - dibenzyls are obtained by oxidation of chloro-substituted 2-nitro-toluene, e.g. with amyl nitrite, to form the corresponding dihalogen - substituted 2.21 - dinitrodibenzyls, which is then catalytically hydrogenated.  In examples: (1) 2-nitro-4-chlorotoluene is treated in ether with amyl nitrite in the presence of sodium ethoxide to give 2.21-dinitro-4.41-dichlorodibenzyl which is hydrogenated using Raney nickel to 2.21-diamino-4.41-dichlorbenzyl. The latter is converted to the diphosphate which on heating with polyphosphoric acid (from orthophosphoric acid and phosphorus pentoxide) gives 3.7-dichloro-iminodibenzyl; (2) from 6-chloro-2-nitro-toluene, 1.9-dichloroiminodibenzyl is prepared, 2.2-dinitro-6.61-dichloro - dibenzyl and 2.21 - diamino - 6.61-dichloro-dibenzyl diphosphate being formed as intermediates.
