Title: Label cutting and folding machine
IPC: B31D1/02
Filed: 1924-01-28
Abstract: 218,588. Rosenthal, A., and Rosenthal, M. Aug. 6, 1923. [Convention date]. Making labels.-In a machine for cutting and folding labels the web of material is fed to the cutting and folding devices by a clamp, while an auxiliary clamp simultaneously carries the last folded label from the folders to a packer tube. The webfeeding clamp 21 and the label-delivery clamp 46 are mounted on a cam-operated compound slide so that they are caused to travel in a rectangular path, first from the position shown in full lines in Fig. 10 to the position shown in broken lines, then at right-angles to this direction to carry the end of the web 10 past the cutter 22 to the folders 25 and the last-folded label from the folders to the packer tube 59, and in another two movements to return to the initial position. In this last movement, the closed jaws 21 are opened by a roller 213 which is mounted on the pivoted jaw running beneath a fixed inclined bar 220, Fig. 4, and a spring latch 216 holds the jaws open until they advance to grip the web, when they are released from the latch by a fixed claw 226 and allowed to close. The jaws 46 are opened and closed by a pivoted bar 53, upon which the lower movable jaw always rests, being lowered and raised by a lever 55 operated by a cam 58 on the shaft 45. The web 10 is drawn by the feeder beneath a brake pad 12, and if it has been printed the printed matter can be adjusted with relation to the cutter by adjusting a deflector 19, Fig. 2, by means of a set-screw 20. Pivoted fingers 79, Fig. 8, support the labels deposited above the packer tube 59, and when a plunger 66 is depressed by a lever 68 and a cam 74, Fig. 4, to press a label into the tube the fingers are withdrawn against the action of springs 80 by a toggle 83 actuated by a lever 88 and a cam 90. The tube 59 delivers the labels directly into the packages to be filled, and the pile of labels is supported within the tube and package by a block 91, Fig. 8, formed in two parts hinged together at 92 and pressed apart by a spring 93 so as to grip the tube frictionally. When a package is removed, a spring shutter automatically closes the tube. Tiie machine is stopped automatically after a predetermined number of labels have been delivered by means of an adjustable and screw-operated sliding nut coming into contact with a stop and thereby operating a clutch.

Filed: 1966-01-18
Abstract: 1,120,382. Water filters. JACUZZI BROS Inc. 18 Jan., 1966 [13 Oct., 1965], No. 2286/66. Heading B1D. A filter for swimming-pool water comprises a tank, containing a filtering bed of sand 117 supported by an underdrain consisting of one or more layers of anthracite pieces bonded together by epoxy resin to form an integral porous mass. During filtering flow, a pump delivers water to the central part of valve 20 (Fig. 3, not shown), and filtered water leaves the underdrain up central tube 37 to valve outlet chamber 63. When the hand operated valve is shifted to the left (Fig. 2, not shown), the pump delivers water to tube 37 and the bed 117 is backwashed, dirty water discharging to waste by pipe 135. During backwashing the sand bed expands and stabilising grid 131, which is slightly denser than water, slides up tube 37. In manufacture, the anthracite is coated with resin, then poured into the tank in successive layers of increasing fineness, and sets bonded to the tank, during which process drainage cage 31 is fitted with a tube to exclude the anthracite. The sand bed is added on site, and, after assembling halves 3, 5 of the tank together, further sand may be added through the opening in the top prior to fitting valve 20. This buries grid 131, which assumes its proper place during subsequent backwashing. The tank has an air vent 104, a drain plug 27 and legs 7. In Fig. 4 (not shown) the tank and other items are of plastics, the grid (175) is of flexible rubber to permit its insertion through the upper valve aperture. Grid (175) is fixed on the central tube and does not extend to the tank wall. The pieces of anthracite in the finest, upper, layer are coarser than the sand.

Filed: 1939-01-25
Abstract: 524,286. Television. JONES, W., and PYE, Ltd. Jan. 25, 1939, No. 2649. [Class 40 (iii)] An arrangement for separating synchronizing impulses of different duration in television and like systems comprises a differentiating circuit to which all the synchronizing impulses are fed in the same phase, the differentiating circuit being such that in the output thereof pulses corresponding to the synchronizing impulses of one duration appear in one phase whilst pulses corresponding to the synchronizing impulses of another duration appear in another phase. The pulses of different phases are then separated by a uni-directional conducting device. As shown in Fig. 4 the circuit comprises an input condenser C and resistance R connected to a thermionic valve from which the output is obtained. The usual set of line and frame impulses shown in Fig. 1 is fed into this circuit of which the condenser C and resistance Rare given such values that the leading edges of the short line impulses 1, Fig. 1, all cause sharp pulses a<SP>1</SP>, Fig. 2, to be given out by the circuit, whilst the longer frame impulses 2, Fig. 1, after giving a sharp output pulse b<SP>1</SP>, Fig. 2, in the same phase as a<SP>1</SP> at the first leading edge of the first impulse then yield a series of sharp output pulses c<SP>1</SP> of opposite phase at the trailing edges. Preferably the condenser C does not discharge fully during the line impulses, in which case the output is as shown in Fig. 3. For example, for the usual train of signals in which the line impulses last .00001 seconds, the value of C may be .000217 microfarads and of R 20000 ohms ; and with these values the condenser discharges to one tenth of its initial charge during a line impulse.
