Title: Apparatus for discharging coke from coke ovens
IPC: C10B41/04
Filed: 1972-09-22
Abstract: 1437080 Safety means for use in discharging coke from ovens SIMON-CARVES Ltd 17 Sept 1973 [22 Sept 1972] 43868/72 Heading F4B Safety means prevent discharge of coke from a coke oven 10 by a ram 13 unless a coke guide machine 14 and a coke receiving car 16 are properly aligned with the oven and ram machine 11. The ram machine 11, coke guide machine 14 and coke receiving car 16 run on rails 12, 15 and 17 respectively and each may be controlled manually by an operator in a cabin on their respective machines. When the apparatus is properly aligned, electromagnetic signals can be transmitted from the car 16 to a guide machine 14, from the guide machine to the oven 10 and from the oven to the ram machine 11 using aerials 18, 19 and coils 20 to 25. Fig. 2 shows the circuitry which includes amplifiers A, relays R and relay contacts r. Associated with the coke receiving car there is a signal generator 26, a dead mans handle 28, an aerial 18 which is at the front of the car and an aerial 19 which extends the full length of the car. Associated with the coke guide machine there is a signal generator/power supply 27, a switch 31 which becomes closed when the guide machine is racked up to an oven to be discharged, a manual push button switch 29 and a manual emergency cut-out switch 30 which is normally closed. At the ram machine, when a signal is received, relay contacts r4/1 close to complete a circuit to an indicator lamp or audible alarm, and contacts r4/2 close to free an otherwise operative mechanical interlock device which normally prevents operation of the ram machine.

Abstract: 890,953. Higher significant figure detectors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 22, 1960 [Dec. 30 1959], No. 44022/60. Class 106 (1). A highest significant figure detector comprises signal generators 26 to 35, one to each order of the number, which produce outputs when an 0, 3 or 6 bit of a 2-out-of.5 coded decimal digit is input, the outputs being applied to windings 71 to 80 on cores 51 to 60. Each winding is in series with contrary windings 61 on lower order cores which if energized cancel the effect of the windings 71 to 79 so that only that core associated with the highest order digit is set and produces an output on terminal 91. Reset windings 92 are provided and the set core produces a second output, of opposite polarity to the first at its terminal 91 on application of a reset signal.

Abstract: 1,165,696. Tape guides. INTERNATIONAL COMPUTERS Ltd. 17 Jan., 1967 [19 Oct., 1965], No. 44330/65. Heading G5R. A fixed tape guide for guiding an inherently flexible tape includes lateral guide means operative to engage opposite edges of the tape and a curved surface providing a curved path for the tape immediately prior to and during its passage between the lateral guide means, the curvature of the path being only sufficient to cause the tape to have increase lateral stiffness. As shown, a tape guide 9 has a convex surface 10 over which the tape is drawn. Preferably the parts of the surface which lie at opposite ends of the tape contact area are of similar curvature; preferably the curvature is constant throughout, so that the tape guide may be an element cut from the periphery of a circular stock member. As shown, the lateral tape guiding means consist of a fixed portion 11 having a tapecontacting part 15, and a spring-urged movable portion 14 contacting the other edge of the tape. The guiding surface may be concave, in which case it may be formed with apertures connected to a partial vacuum; alternatively or additionally, the tape may be forced into contact with the surface by pressurized air. As a further alternative, the devices which feed tape to, and receive it from, the guide, may be so arranged and driven that the tape is driven into abutment with the guide (not detailed).

Abstract: 1,269,399. Automatic exchange systems. SIEMENS A.G. 17 Sept., 1969 [18 Sept., 1968], No. 45714/69. Heading H4K. A PBX includes at least one group of subscribers who can answer each other's calls using their individual subsets. When one of the subscribers becomes aware (by means not specified) that another one is being called, he lifts his own handset and dials a special code into the register to which he is automatically connected. The register seizes a common control which tests the priority of the subscriber and, if this is in order, applies an identification potential via a diode decoupling network to all the inlets (cwires) of the group on the switching network. Consequently in the feedbridge which has been seized for the incoming call, a relay that has been prepared by the ringing circuit comes-up so as to identify the feedbridge to the control. The latter then releases the original connections, viz. the incoming and the register connections, and completes a connection between the justidentified feedbridge and the subscriber who volunteered to answer the call. The identification potential is provided by a capacitor discharge.
