Title: Paper feeding mechanism
IPC: B65H3/44
Filed: 1946-07-24
Abstract: 623,405. Feeding sheets. ADDRESSOGRAPH - MULTIGRAPH CORPORATION. July 24, 1946, No. 22070. Convention date, Aug. 31, 1945. [Class 100 (in A machine for feeding sheets to printing and like machines in which sheets are fed normally from a pile A by an oscillating suction separator 32 to feed rolls 30, 31, is constructed with a supplemental device to supply extra sheets to the same separator, and enables a small number of sheets of different colour or character to be printed. The extra sheets are supported on a detachable tray 60 formed of side members 63 connected to bottom plates 61, 62, adjustably connected by pins 66 and slots 65 for dealing with sheets of different widths. Notches 70 in the sides 63 fit over the shaft 35 of the means for operating separator 32, and the tray rests against an adjustably-mounted bar 51, and hooks 71 at the front engage under a pivoted bail 40 which normally rests on the pile A and controls the action of ratchet mechanism for raising the pile-board 16. Extensions 72 of the hooks form side guides for the supplemental sheets which are placed under the bail 40 and against front pile stops. The separator 32 acts upon the supplemental sheets similarly to the normal sheets. The bar 51 carries side registering devices for the pile A, and one or more weighted tapes 53 to control the rear edge of the pile. The pile-raising gear may be handactuated to adjust the pile, and is controlled automatically by the bail 40 which controls the vertical position of a bar 94 which is reciprocated by a lever 91 actuated by a link 90 from the printing-machine. The lever 91 also oscillates a pawl carrier 98, and the bar 94 actuates, by means of a pin 110, a latch 111 which prevents the pawl from actuating its ratchet when the pile does not need raising. The pile-raising gear forms the subject-matter of Specification 630,336.

Title: Manually controlled pressure regulator valves
IPC: G05D16/10
Filed: 1975-05-22
Abstract: 1454720 Valves; change speed control GENERAL MOTORS CORP 22 May 1975 [12 June 1974] 22101/75 Headings F2V and F2D A manually actuated valve for providing a variable pressure signal for the control of an automatic transmission includes means to maintain the control pressure at a predetermined level in the event of breakage of the actuation mechanism. The valve comprises a landed spool 34 the axial position of which controls communication between a pressure inlet passage 26 and a control pressure output pasage 24 and between the latter and an exhaust passage 22 leading to drain via duct 60 and a normally unseated ball valve 96. The pressure in control passage 24 is also communicated to passage 20 to act on land 40 and urge spool 34 leftwards against the bias of manually set plunger 48 acting on the spool via spring 50. Plunger 48 is positioned by a lever 66 pivoted on bracket 68 by pin 70 and biased out of contact with the plunger (clockwise in Fig. 1) by a torsion spring 72. The lever 66 is urged in the opposite direction, however, by a cable 78, or other control linkage, connected via an engine carburettor (108, Fig. 4, not shown) to an accelerator pedal (104). A rod 84 has a U-shaped portion 86 extending through a slot 80 in the base of bracket 68 and an upstanding portion 90 normally urged by spring 100 to unseat ball valve 96 and thus permit exhaust fluid from passage 22 and duct 60 to flow to drain via port 92. An arm 88 extends from the U-shaped portion 86 to engage the undersurface of a projection on lever 66 (Fig. 3, not shown). Should cable 78 break, torsion spring 72 causes lever 66 to pivot clockwise thus moving rod 84 downwardly so that ball valve 96 blocks exhaust port 92. Thus, since the control pressure line 62 from passage 24 is connected to the pressure supply line 58 from pump 54 via a restriction 64, the control pressure is maintained at a high value equal to the supply pressure even though the manual control of valve spool 34 has been lost.

Filed: 1949-08-29
Abstract: 666,040. Parachutes. STEVENS, A, H. (Switlik Parachute Co., Inc.). Aug. 29, 1949, No. 22374/49. Class 4 In order to prevent deterioration of the fabric of a parachute canopy it is packed in a hermetically seated container from which the air has preferably been evacuated. As shown the parachute 46 is packed in a hermetically sealed evacuated container 40 mounted beneath a chair seat 21. which is attached to a harness 29 and may be released from the remainder of the chair. A valve 50 in the base of the container enables the latter to be connected to a vacuum pump or permits the introduction into the container of a gas such as nitrogen. When the parachute is to be used a handle 57 at the side of the chair is operated to withdraw a plug 55 from the base of the container 40 to destroy the vacuum, and also to pull on a wire 37 to break plastic seals 36a between the seat 21 and container 40, the latter of which is thus released. The parachute is then deployed by manual or automatic operation of a static line 47. A pressure gauge, and moisture-indicating substance such as silica gel, may be mounted behind a window 53 in the parachute container.

Filed: 1930-07-24
Abstract: 359,931. Turning-gear. MOTORENWERKE MANNHEIM AKT.-GES. VORM. BENZ ABT. STATION‰RER MOTORENBAU, Mannheim, Germany. July 24, 1930, No. 22400. Convention date, July 24, 1929. [Class 7 (v).] For starting compressorless Diesel engines, an auxiliary flywheel is coupled to the engine and both the engine and the auxiliary flywheel are set in rotation by cranking means whilst compression in the cylinders is relieved. As shown in the Figure, an auxiliary flywheel e is carried by a shaft l slidable to bring a pinion f thereon into engagement with teeth on the main flywheel c. This movement compresses a spring g and brings a collar k on the shaft into engagement with retaining lugs on the weights h of a centrifugal governor pivoted on the auxiliary flywheel. The engine is cranked and the flywheel e set in rotation by means of a handle b, or by an electric motor geared to the flywheel c, whilst the compression is relieved. Compression is then restored and, on the starting of the engine, the weights h release the shaft l, which is moved axially by the spring g to disengage the pinion f. A spring coupling may be provided between the pinion f and its shaft. In a modification, the movement of the pinion f into engagement with the main flywheel c is effected by the movement of the cranking-handle b into engagement with the engine shaft, a lever engaged by the handle b being connected by a rod to the shaft l. In a further form, the auxiliary flywheel e is connected to the shaft l of the pinion f through change-speed gearing by which the gear ratio may be varied after setting the flywheel e in rotation. Specification 295,854, [Class 7 (v), Internalcombustion engines, Starting, &c.], is referred to.

Title: Improvements in or relating to the manufacture of artificial sheet material, and articles made therefrom
IPC: D06N3/00
Filed: 1937-08-14
Abstract: 500,879. Windows and sun-blinds. WALKER, W. Aug. 14, 1937, No. 22405. [Class 20 (iii)] [Also in Group IV] Artificial sheet materials, reinforced over portions of their area by a textile fabric impregnated with the substance of the sheet materials, are made by depositing film-forming solution on a casting-bed, the surface of which is formed partly by a textile fabric and partly by a protective coating from which the sheet material may readily be removed. The filmforming solution may be coloured and the articles produced may be used as transparent sun-blinds. If the protective coating is applied sufficiently thin over portions of a textile fabric, the appearance of a textile fabric is imparted to the non-reinforced portions of the sheet material subsequently formed thereon. As shown in Fig. 1, a layer 3 of, e.g. cellulose acetate, is formed on a fabric provided, except for the margins 4, with a protective coating, e.g. of wax, gelatine, or ethyl cellulose. When the cellulose acetate layer has dried, the centre portion 1 of the fabric is stripped off leaving the cellulose, acetate sheet with marginal fabric reinforcement. Separation of the centre portion of the fabric from the margins is facilitated by providing a serrated line of cuts before application of the cellulose acetate layer. As shown in Fig. 4, the sheet material is provided with reinforcing strips across its width as well as at the margins, and it is thus divided into panels.

Abstract: 301,352. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Aug. 27, 1927. Splitting the phase of speech currents. - A phase difference between two portions of a modulating current, which may comprise speech frequencies, is obtained from a single source by producing in two channels a carrier wave modulated by the current with a phase difference between the channels. Fig. 1 shows a low-frequency input 1 divided into two branches A1, A2. The branch A1 comprises the balanced modulator M1 and detector Dl with an oscillator 01, the output of which is applied to the detector through a phase shifter PS1. The low-frequency component is selected by the filter LPF and is phase displaced with respect to the branch A2. In a modification, Fig. 4 (not shown), the phase displaced low-frequency current is obtained by modulating a carrier source and applying the modulated current to a resistance in series with an inductance; these form the inputs respectively to a pair of demodulators in the outputs of which, through filters, the phase displaced low-frequency currents are obtained.
