Title: Improvements in devices for separating sheets from a pile of sheets
Inventor: MEYLAN PAUL
IPC: B65B41/06
Filed: 1951-07-02
Abstract: 702,559. Feeding sheets. SAPAL SOC. ANON. DES PLIEUSES AUTOMATIQUES. July 2, 1951, No. 15650/51. Class 100 (1) Sheet-separators.-Sheets, such as labels, are separated individually from a pile 2 by a reciprocating separator 5 which separates the bottom sheet from the pile when moved in one direction, and has suc-. tion means for withdrawing the sheet when moved in the opposite direction. The separator 5, which is reciprocated by a crank-arm 6, has a bevelled end 7, and is provided with a chamber 11 communicating with a suction duct 12. The lower face of the separator is formed by a plate 13 having suction apertures 14 therein. A vertically-reciprocating suction tube 8 situated below the pile 2 has a plate 16 which normally supports the pile. When the separator '5, Fig. 3, is about to pass between the two bottom sheets of the pile, the corner or edge 15 of the bottom sheet 10 is pulled downwards by the suction tube 8 so that the edge 7 of the separator can be inserted between the last two sheets. As the separator 5 moves into the pile, the plate 16 and tube 8 are lowered, so that the bottom sheet rests on the plate 16, and the separator supports the pile 2. The suction tube 8 now releases the bottom sheet which is then sucked upwards against the lower face of the separator 5, and the latter moves rearwardly to withdraw the sheet from the pile to a position overlying a member 4. The sheet is then released by the separator and falls into the position shown at 3 on the member 4 which forms part of an automatic packing or folding machine.

Title: Improvements in or relating to catheters
IPC: A61M25/02
Filed: 1931-05-28
Abstract: 361,818. Catheters. DOW, M. F., 18, Kidderpore Gardens, Hampstead, London. May 28, 1931, No. 15686. [Class 81 (ii).] A flexible catheter 1, Fig 1, is formed at its end with a shaped-away portion as at 3 opposite the usual aperture 2 in order to reduce the part within the bladder. The catheter is preferably em ployed with a guide tube 8 Fig. 2, attached by studs 9 .to a pad 7 carried by ar elastic belt 10 and may initially be formed of curved shape as at 1<1> in order tc secure close contact with the abdominal wall 6 and thereby reduce leakage. Ir addition or alternatively the catheter may be former with a bulged portion 12 close to the wall of the bladder or within the abdominal wall. The curved and bulged catheter may be made by inserting a deformable wire into the straight tube, doubling the tube and wire back upon themselves, coiling the tube around the doubled-back portion and " setting " the catheter as by boiling. To prevent movement of the pad 7 a rigid bar 13, Fig. 5, or a pair of such bars is or are detachably connected to the studs 9; the bar may be cut away as at 14 to prevent interference with other surgical appliances, for example a truss. The free end of the catheter may be closed, when the receptacle commonly employed is detached, by a hollow glass stopper or by a transparent rubber cap attached to a beaded vulcanite tube, thus permitting the necessity for the re-attachment of the receptacle to be observed.

Abstract: 495,430. Fastenings. SLEIGH, H. L., CHESTON, A. S., and BOOTH, J. H. June 8, 1937, No. 15817. [Class 44] A latch or like fastener comprises a single attachment plate 5, a movable arm 9, disposed on one side of the plate and having a shank 10 extending through a hole 6 in the plate, an integral stop on the shank engaging the other side of the plate to retain the arm in position, and spring means for urging the arm into a terminal position. The spring 14 acts over a dead-centre and stops 16, 17 limit movement of the arm 9 under the action of the spring. The hole 6 has a pair of square recesses 8 formed at opposite ends of a diameter inclined to the axis of the plate. The shank 10 of the arm 9 has complementary projections 11 in line with the arm 9. To assemble the latch, the shank 10 is first passed through the hole 6, the projections 11 passing through the recesses 8, and the arm 9 is turned until the projections 11 engage behind the plate 5. The lug 16 on the plate is then bent up and acts as a stop to prevent the arm 9 being turned to a position where it can be removed from the plate. The spring 14 is hooked into a lug 15 on the plate 5 and a lug 13 on the arm 9. The shank 10 has a square or other non-circular hole 12 for passage of an operating spindle or a removable key. The arm 9 may be cast or die-cast with the shank 10 and lug 13 integral with it and the lugs 15, 16, 17 may be formed separately from the plate 5 and secured in place by welding or riveting.

[Class 38 (iv)] A D.C. are lamp is supplied from A.C. mains through a tapped transformer and rectifier which is arranged to operate only when the carbons are struck and to be cut off from supply when the arc is extinguished. The transformer, rectifier and associated connection equipment may form a self-contained unit merely requiring connection to the supply mains and to the lamp, and the rectifier, which is preferably of the mercury arc type, may be mounted on a spring carrier in the unit to enable in situ shipment. In the system shown, lamp terminals +, - are supplied from the A.C. source through a mercury arc rectifier e, smoothing choke g, transformer b, ballast reactor c and combined mains switch and current regulator a. A cooling fan p and indicator lamp rare energized upon closure of the mains switch. When the carbons are struck the dipperoperating coil m is energized from the transformer tappings b<1>, b<2>, the rectifier fires and the resultant flow of D.C. in the lamp circuit energizes a relay h which at its contacts K<1>-K<3> connects a smoothing condenser l across the lamp and opens the starting circuit of the rectifier. Upon extinguishing the lamp by interrupting the D.C. circuit, relay h reestablishes the initial starting connections. In a modified arrangement, the ballast choke is combined with the transformer. A surge resistor n may be connected across the rectifier anodes.

Abstract: 375,512. Torsional oscillation dampers. GENERAL MOTORS CORPORATION, Detroit, Michigan, U.S.A. May 30, 1931, No. 15911. Convention date, March 25. [Class 108 (iii).] Torsional oscillations in shafts are damped by a weight rotated from the shaft through a friction clutch in which the pressure exerted varies with variations in the speed of the shaft. Such variations are obtained from a driving member for an accessory such as a fan or dynamo, the resistance of which 'increases with speed. The rotating weight 11 is driven from the shaft 15 through a friction disc 25 located between _the weight 11 and the.plate 20 secured to the shaft. The friction surfaces are pressed together by springs 30, which exert a constant force, and also by the wedging action due to the driving effort exerted through a V-belt 13 driving the fan on a motor vehicle. The belt wedges between two inclined surfaces formed respectively on a flange 23 fixed to the shaft 15 and on one side of the weight 11.

Filed: 1955-06-06
Abstract: 773,006. Radiation detectors. GENERAL ELECTRIC CO. June 6, 1955 [June 9, 1954], No. 16207/55. Class 40 (3). Apparatus for detecting light intensity variations comprises a semi-conductor device having a pair of electrodes, the effective capacitance between which varies in accordance with the intensity of light falling on a photo-sensitive area in the device, connected in an oscillatory circuit so that variation in the said capacitance causes variation in the oscillatory frequency of the circuit. In Fig. 1, the oscillator circuit uses a transistor 11 having an emitter 13, base 15, and collector 17. A tuned circuit comprising capacitances 23 and 25 in parallel with an inductance 27 is connected between the collector 17 and one end of a choke 21, the other end of which is connected to the emitter 13. The base 15 is connected to the said one end of the choke 21 through a biasing network 22 comprising a capacitance 29 in parallel with a capacitance 31 and variable resistance 33 in series. A battery 19 is connected in series with the coil 11. In addition, the junction between capacitances 23 and 25 is connected to the emitter, providing feed-back from the collector-base circuit to the emitter-base circuit in the correct phase for maintaining oscillation. Light from a source 12, the variation of which is to be measured, is focused on to the photosensitive collector, varying the capacitance between the collector and other electrodes. Since this capacitance is effectively in parallel with the tuned circuit 23, 25, 27, the resonant frequency of oscillation varies. A coil 49 couples the tuned circuit to a frequency discriminator 14 and an indicator 16. In an alternative oscillator, Fig. 3 (not shown), there is inductive feed-back from the collector-base circuit to the emitter-base circuit.
