Title: Improvements in Forging Machines or like Presses.
IPC: B21J9/12
Filed: 1917-02-26
Abstract: 113,643. Massey, E. & S., and Massey, H. F. Feb. 26, 1917, Presses.-Relates to forging and like presses of the type in which the ram has a reciprocating movement of constant length and in which the position of this reciprocation is determined by admitting to or releasing from the ram-cylinder a quantity of water, and consists in various improvements in such presses. In the arrangement shown in Fig. 1, the ram d is balanced by a weight g; but springs or gaseous or fluid pressure may ba substituted. The reciprocating movement is transmitted to the ram by a pump-plunger m driven by a steam-engine, electric motor, &c. A raised tank a contains water and is connected to the ram-cylinder by a valve-box s, which also contains a valve by which water can be exhausted from the ram-cylinder to the waste tank w. The tank u is filled from the tank w by a constantlyrunning pump x. By means of the valve-box s .the position of reciprocation of the ram is varied by the admission of water from the tank u or exhaust from the ram-cylinder. Connected to the deliverv pipe of the pump 1 is a safety-valve 8 controlled by the pump cross-head so that the valve is closed and the pressure raised towards the end of the stroke of the ram, the pressure at the beginning of the stroke being determined by the load on the safety-valve 8. A second safety valve 7 determines the terminal pressure. Modifications in the valve arrangement are shown and described.

Title: Unbalanced current protection system for use with paralleled generators
IPC: H02H7/06
Filed: 1964-01-27
Abstract: 1,020,101. Protective systems. WESTING- HOUSE ELECTRIC CORPORATION. Jan. 27, 1964 [Feb. 6, 1963], No. 3353/64. Heading H2K. [Also in Division H3] In an unbalanced-current protective system for a plurality of paralleled generators, current transformers are connected in a closed loop circuit so that auxiliary transformers are energized.in accordance with the difference between the current of the associated generator and the mean of the currents supplied by all the generators. Each of the auxiliary transformers 54 is connected to a static circuit, Fig. 2, such that when the difference current due to unbalance reaches a predetermined value, the output voltage of the auxiliary transformer secondary winding 55 is sufficient to cause a Zener diode 104 to break down and render a controlled rectifier 99 conductive, a Zener diode 96 having broken down at a lower predetermined value. When the rectifier 99 conducts, it renders a normally non-conducting transistor 106 conducting. This inturn causes a transistor 114 to cease conducting, so that the voltage across it becomes sufficient to break down a Zener diode 119 and energize a relay 122 and an indicating lamp 124. When the unbalance is reduced below the lower predetermined value, the diode 96 ceases to conduct, so that the controlled rectifier 99 and the transistor 106 cease to conduct. The transistor 114 now conducts and relay 122 releases. In a modified arrangement, Fig. 3 (not shown), a single Zener diode and a single transistor are used, the two predetermined values being obtained by the alternate use of two potentiometers under the control of changeover contacts of the relay.

Title: Improvements in or relating to automatic couplings for railway vehicles
IPC: B61G7/10
Filed: 1936-02-06
Abstract: 466,617. Couplings and draw-gear for vehicles. BAKER, W. S. GRAFF-, and BLACKSHAW, J. E. Feb. 6, 1936, No. 3631. [Class 103 (v)] In order to retain an automatic coupling for railway vehicles when uncoupled in a central position, whilst permitting it to swing laterally when coupled, unchecked by spring centralizing means, the coupling is equipped with a locking device adapted, whenever the uncoupled coupling is in a central position, automatically to lock the same, but to be operated to an unlocking position by a complementary coupling in the initial stage of a coupling action and to remain in such condition so long as the two vehicles are coupled. In the construction shown a coupling of the kind described in Specification 435,579 is fitted on its under side with a pivoted locking lever 17, the tail 16 of which, when the coupling is in a central position and uncoupled, engages by gravity in a recess 15 in a plate 14 carried by the vehicle underframe and so locks the coupling against lateral displacement. In effecting a coupling, the bar 21 of the opposed coupler engages the head 19 of the lever 17, which projects through a slot 20 in the coupling, raises the tail 16 from the recess 15, and so frees the coupling for lateral swinging e.g. in negotiating a curve. A spring may be provided to urge the tail 16 to its locking position, and prevent it from being displaced by jolts of the vehicle.

Abstract: 372,374. Looms with stationary weft supplies. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and POOL, W., of British Celanese, Spondon, near Derby. Feb. 6, 1931, No. 3896. [Class 142 (ii).] Relates to looms in which weft is drawn in loop form between weft trapping devices at the sides of the loom, the limbs of the loop being inserted by a dummy shuttle in separate sheds to form a hairpin, and the bight of the loop forming the selvage. A longer length of weft must be available for the first pick of each loop, and in order that different lengths may be available on the two picks, while allowing loops of substantially equal limbs to be drawn, the cutting means are arranged to sever the limb of the loop connected to the weft supply at some distance from the trapping device on the side remote from the supply. Fig. 8 shows trapping devices 21 for supplying weft to both sides of the loom. The weft loop at the left has been drawn by the travelling member 14 and the limb 43 released from the jaws of the trapping device and ready to be picked by the shuttle 44. After it has been picked, it will extend around the guide finger 38, the part between the selvage and the finger forming part of the second limb, which is provided with a correct length by arranging the cutter 28, 29 for severing the weft from the supply 42 at a distance, as shown, from the trapping device. The travelling members 14 for drawing the loops between the trapping devices are mounted on an endless chain and move the weft into position for severing, to a depresser by which it is presented to the shuttle, and to the loopretaining finger. Guides are provided to prevent the weft from fouling, while a guide roller at a bend of the chain is provided with a cover-plate and guard for the same purpose. The chain is guided further in a tunnel near the finger 38 to present the member 14 accurately. The cutter, which operates simultaneously with the raising of the finger 38 to release the limb for the second pick, comprises fixed and movable jaws 29, 28, Figs. 5 and 7, the movable jaw having a beak 49 for preventing entry of a wrong part 48 of the weft between the jaws, while the weft to be severed is led through a notched plate 47. The movable jaw is operated to close quickly through lever and cam mechanism geared to the chain. Specifications 346,850, 362,979, 372,373, and 372,375 are referred to.

Filed: 1976-02-03
Abstract: 1511464 Wide-band TDM systems INTERNATIONAL STANDARD ELECTRIC CORP 3 Feb 1976 [13 Feb 1975] 04172/76 Heading H4K In establishing a high quality connection, i.e. one using two or more time slots per frame, between two subscribers in a TDM network a synchronizing arrangement monitors the incoming time slots (e.g. x1-x4) carrying information to be transferred and ensures that outgoing time slots (e.g. y1-y4) assigned to the connection are associated with the incoming time slots in such a manner that the time sequence order of the information is preserved. To do this, a binary reference code m is increased by one-Fig. 3-each time an outgoing slot is detected and is decreased by one each time an incoming slot is detected. When all the time slots involved in a connection have been monitored in this way, the outgoing time slot corresponding to the maximum count obtained, e.g. y4 corresponding to m+2, is identified. This slot is then associated for information transfer purposes with the incoming time slot immediately preceding it in time-e.g. x2- and the remaining slots in the connection follow this pattern of association (Fig. 2). It is shown in the Specification that by using the above procedure (a) an outgoing time slot does not occur earlier than the incoming time slot with which it is associated and (b) the elapsed time between an incoming slot and its associated outgoing slot does not exceed one frame.
