Title: Improved method for capping vessels with externally beaded mouths
Filed: 1931-11-03
Abstract: 374,758. Capping bottles &c. CROWN CORK & SEAL CO., Inc., Highlandtown, Baltimore, U.S.A.-(Assignees of Booth, G. W.; c/o Crown Cork & Seal Co., Highlandtown, Baltimore, U.S.A.) Nov. 3, 1931, No. 30450. Convention date, July 27. [Class 125 (ii).] A method of capping a vessel having an externally beaded mouth consists in positioning a disc of ductile material over the mouth and ironing the margin of the disc over the bead by an ironing operation not applied to the extreme edge of the disc, which edge buckles freely under the bead. As shown, a disc is pressed on a beaded mouth vessel C by a presser tool 20 attached to a spring-pressed stem 19. A segmental throat 22, surrounding the tool 20 and rocking about its upper bevelled edge 24<1> which presses against a plate 26, is yieldingly held together by an encircling spring 30. On relative movement between the vessel and the plate 26, i.e. when the tool 20 is pushed upwards against the spring 21-the segments 23 expand and the edges 27 thereof iron the inner part of the margin over the bead, crimps 17 being produced which lock the cap under the bead. When the throat is closed the lower edge is of slightly less diameter than the upper end, which ensures that the drawing action is performed almost entirely by the edges 27 and not by the inner faces of the segments 23, thus ensuring an efficient closure.
Patent GB-305084-A (GB)
Abstract: 305,084. Beatty, W. E., (Bell Telephone Laboratories, Inc.). Oct. 28, 1927. Pressure gauges.-In connection with a process for japanning articles, a device for measuring the air pressure in a combustiontube 57 is described, wherein a tube 116, Fig. 7, is inserted into tube 57 and is connected to a bulb 117 having a resistance element 118. An opening 119 allows a current of air to pass over the element 118 depending on the pressure in tube 57. The element 118 forms one arm of a Wheatstone bridge circuit and is balanced by a similar element 122. The air current passing over element 118 cools it and alters its resistance, and the galvanometer 124 may be calibrated to read the pressures in tube 57 directly.

Title: Improvements in telephonic repeater systems
IPC: H04B3/20
Filed: 1931-11-05
Abstract: 391,827. Two - way transmission. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Horton, A. W.; 160, Prospect Street, East Orange, New Jersey, U.S.A.) Nov. 5, 1931, No. 30656. Convention date, Dec. 10, 1930. [Class 40 (iv).] In a system involving a 4-wire section, e.g. New York- Newfoundland, coupled to a trans-oceanic cable, -a local noise source feeds the telephone line while the receiving path is disabled to prevent the alternate noisy and silent periods as the cable is switched over, which in prior systems have proved a distraction. The noise source NS is arranged, with the help of an equalizer EQ, to simulate the cable noise as closely as possible. As shown, the receiving path RC is normally clear and the transmitting path TC is interrupted at both ends. In addition the transmitting amplifier is paralysed. Speech arriving from the cable takes exclusive control of the switching means even if speech is already in the transmitting path between A and B by paralysing 65, to prevent the preparation of the transmitting amplifiers, and operating 63, 20. Provided no speech is coming from the cable, speech from the land line energizes 22, 58 to extend the transmitting and interrupt the receiving paths and to connect up' the local noise source. On arriving at the shore station B, the speech with the help of rectifiers 67, 52 receives the transmitting and paralyses the receiving amplifiers. The anode current or the transmitting amplifiers energizes 70, followed after suitable time intervals by 30, 48, 71, 49, 50, which switch over the cable and finally disable the receiving path. When speech from the land line ceases, 58 may be arranged to hold on long enough for the relays at the other end to fall back. As shown, however, it is assumed that 58 falls first and consequently a second noise source NS is provided at B and feeds the land-line until the cable is switched back. In some cases, 58, 63 may be omitted and the single noise source is then provided at the station B.

Title: An improved process and apparatus for weaving together the ends of similarly woven belts and bands
IPC: D03D3/00
Filed: 1926-12-03
Abstract: 266,676. Engel, K. Feb. 27, 1926, [Convention date]. Darning.-The ends of a belt or of several belts of the same weave are connected by working the warp threads of the ends to be connected alternately on to a series of bars spaced apart by the distance of the weft threads and splicing each warp to the associated warp of the other end and then drawing a weft thread through the spaces occupied by the bars as these are withdrawn. The bars or needles d have an eye at each end and are supported between clamping bars a, b in a position adjacent to the overlapped ends o, p of the belt portions to be connected. Combs f , pivotally mounted at h on the clamping bars, space the needles apart at the distances of the weft threads n<1> of the belt ends. The weft threads are cut along the edges of the belt-ends opposite to the needles and a warp thread o1 from one belt end is worked on to the needles in the same conformation as it had with respect to the weft threads, the end being spliced or knotted as at q to the corresponding warp thread p1 of the belt end p which has been detached. The second warp thread p2 of the belt end p is then worked on to the needles and spliced at r to the detached warp thread o2. When all the warp threads have been worked on to the needles the needles are released from the clamp and the end needle is threaded and withdrawn, thus introducing a weft thread which is threaded into the next needle. This is then drawn out in the opposite direction and so on until the introduction of the weft is completed.

[Also in Division C7] A control arrangement for a large number of electrolytic cells 2 comprises an electronic scanning device 3 connected to the cells through D. C. transformers 4 and feeding a central control unit 1 through an analogue to digital converter 5. The unit 1 takes the form of a digitally-operated data processing device which is programmed to control an order distributer 6 which in turn transmits signals to the electrode setting members 7 for the cells 2, so that the electrode spacing of each cell is maintained at an optimal setting (according to the cell voltage sensed by the transformer 4) or is altered to eliminate short circuit conditions. Members 7 may comprise relay controlled reversible motors and, as shown in Fig.2, selector relays 12 control respective groups of setting gears driven by motors 11 whose direction of rotation is determined by energization of one or other of relays 13, 14. The condition of the relay contacts is monitored by the unit 1 through another electronic scanning device 15, to stop the transmission of setting orders in the event of a relay fault. The distributer 6 may comprise addressable, bi-stable electronic switching stages each associated with a relay 12 and the relay 13 or 14, so that a setting operation lasts for a predetermined time determined by the unit 1. To ensure termination of setting in the event of a fault in the unit 1, the stages associated with relays 13, 14 may be monostable and dependent on pulses from the unit 1 indicative of its condition (correct or faulty). An independent time switch stage 16 also monitors the condition of the unit 1 and, in the event of a fault therein, automatically increases the electrode spacing of all of the cells 2 to prevent short circuits during the inoperative period of the unit 1. The stage 16 may also be used for remote manual control of the electrode settings.
