Abstract: 658,258. Seaming non-metallic sheet material. DUFFY, V. A. Jan. 2, 1948, No. 199. Convention date, Jan. 23, 1947. [Class 42 (i)] [Also in Group XI] Sheets of thermoplastic material are joined together by passing an electric heating current through a metal wire, strip or sheet that is pressed against the sheets of thermoplastic material until they soften and weld together along the area defined by the metal wire, strip or sheet. In Fig. 1, an apparatus for carrying out the above process includes a table top 10 over which is pivoted an elongated metal strip 16 which may be raised by depressing a foot pedal 21. The strip 16 may be the heating resistor or it may support a nickel or other spring-tensioned heating wire 24, Fig. 3, of square, circular or other cross-section, extending along its lower face. The strip 16 may be bent to a desired shape. The table top 10 may have a felt-lined groove in which is a co-operating, spring-tensioned, heating element in a fibre glass sheath. Another embodiment, Fig. 6, for spot-welding plastic sheets together, comprises an insulating rod 63 mounted in a vertically movable frame 52 operated by a lever 57. A nietal disc 66, Fig. 7, is secured to the lower face of the rod 63 and current is supplied by one conductor 68 to diametrically opposite points 69 and 70 on the disc and by a second conductor 72 to diametrically opposite points 73 and 74, the points being uniformly spaced as shown. Copper slugs 76 surround the supply conductors where they are joined to the disc to prevent overheating at these points. The apparatus may be used to weld an air valve having a cylindrical tubular part and a flattened base of plastic material to a sheet of the same material. The metal disc 66 may be replaced by an annular disc supported on, and insulated from, an iron core on which a primary winding is wound, the annular disc constituting a short-circuited turn on the core. An alternative construction is shown in Fig. 8 wherein a rectangular strip of nickel 80 is bent round the lower end of a rectangular insulator 81 as shown, and copper blocks 85 and 86 are secured to the vertical arms of the nickel strip for cooling purposes, current being supplied to the strip by leads 83 and 84 so that the lower face of the nickel strip may form the welding surface. In all cases, the electrical circuits preferably include an electronic timer 33, Fig. 1, so that the current may be automatically switched off after a predetermined time.

Abstract: 1341071 Feeding and delivering sheets XEROX CORP 5 Jan 1971 [12 Jan 1970 (2)] 386/71 Heading B8R Feeding sheets.-Articles such as newspapers are separated from the bottom of a pile 20 by a reciprocating member driven by a slider 19 and coupled thereto by a latch 15 releasable by a solenoid 6 to stop the separation, and are then fed by rollers 11 and a conveyer 26 past a sheet sensor 75 and the head 8 of an addressing- machine. A gate 9 prevents double feed. Delivery sheets.-Sheets are delivered from the addressing-machine by the conveyer 26 on to the bars of an elevator 12, and against a plate 51 and between side plates, to be stacked. As the stack builds up beneath a sensing skid 55, the elevator is lowered slowly under the control of the skid, until a counter controlled by the sensor 75 records a predetermined number of sheets, whereupon the solenoid 6 is energized to stop the feeder, the lack of sheets passing the sensor 75 causes the action of the head 8 to be stopped, and the elevator, after a delay to allow all separated sheets to reach it, is lowered rapidly until the bars of the elevator pass between the bars of an interceptor 14, on which the stack thus rests. Closing of a switch 92 by the elevator brings the elevator to rest by the disengagement of a clutch and application of a brake, while closing of a switch 94 actuates an ejector 16, which is advanced to push the stack on to a conveyer 24, whence it is removed, failing which a safety switch 126 acts to stop the conveyer. The ejector closes a reset switch 99 which results in the elevator rising rapidly to its upper position, ready to receive a new stack.

Abstract: 1,270,113. Measuring changes in phase. ENGLISH ELECTRIC CO. Ltd. 19 Dec., 1969 [3 Jan., 1969], No. 462/69. Heading G4H. In apparatus for digitally measuring the changes in phase of a cyclic input signal, in which, in each cycle of the signal, the interval between a selected point of a signal of reference phase and a selected point of the cyclic signal is measured by counting clock pulses for this interval, the difference in the number of counted pulses in successive cycles represents the phase change. In the embodiment described for measuring, for example, displacement of a synchro 2, a counter 4 (Fig. 1), receives high-frequency pulses from a source 3, the phase of the reference signal being determined by the time at which the counter resets from full count to zero. The counter is continuously compared with the previous phase value held in a store 8, at equality a signal being sent to an error detector 10. Positive-going zero crossing signals from the synchro result in a latch pulse to a store 7 to store the count in the counter 4 representing the phase of the input signal and to the error detector 10. The error detector enables a reversible counter 12 to count the clock pulses from source 3 between its two input signals, the pulses being accumulated additively or subtractively in dependence on whether the comparator signal leads or lags the latch signal. The count is displayed. The frequency of the clock pulse source may be selected to give a count in inches or metric units.
