Title: Travel recording apparatus for coal-cutters or other mining machines
IPC: E21C35/10
Filed: 1965-09-22
Abstract: 1,116,226. Electric selective signalling. HOUILLERES DU BASSIN DE LORRAINE. 22 Sept., 1965 [25 Sept., 1964], No. 40292/65. Addition to 995,210. Heading G4H. Advance of a coal-cutter or other stoping machine produces two out-of-phase pulse trains to advance a stylus in a drum-type recorder. Movement of a coal cutter produces two out-ofphase pulse trains, corresponding to a repeated sequence of pairs of bits, the two bits of a pair being in parallel and the sequence being 00, 01, 11, 10, or the reverse, depending on the direction of movement. In Fig. 9, the pairs 01, 10, 00 are recognized by ANDs 26a, 27a, 28a, respectively, the first of 01, 10 to arrive setting a corre sponding storage element 30a, 32a. which prevents subsequent setting of the other by means of ANDs 29a, 35. The pairs 01, 10 also set and reset, respectively, a storage element 33a. When 00 arrives, ANDs 31a, 36 are enabled to respond to the set states of elements 30a, 32a, respectively, and the reset and set states respectively of element 33a to produce an add or subtract pulse C or D. AND 28a resets the storage elements after a delay. Thus an add or subtract pulse C or D is produced according as 01 precedes or follows 10 respectively. Fig. 8 (not shown), shows a modification which can only produce add pulses, ANDs 35, 36 being omitted, the former being replaced by a straight connection from 27a to 32a. The arrangements are insensitive to some spurious pulses. The add/subtract pulses drive a motor to rotate a potentiometer wiper to supply a voltage to a pen recorder. As an alternative, the pulses of the sequence can be fed direct to overlapping windings (Fig. 13, not shown) to produce a magnetic, field with which a permanent magnet aligns itself to rotate the potentiometer wiper.

Abstract: 1371729 Pressure die casting machines NIPKI "LEYARSKA TECHNIKA" 1 Sept 1972 [2 Sept 1971] 40761/72 Heading B3F In a low pressure casting machine comprising a mould 7, a reservoir 3 for molten metal, a duct 12 extending from the reservoir to the mould, first and second end plates I and 10, a movable plate 9 and an intermediate plate 4, the said plates being interconnected by columns, the intermediate plate 4 acts as a cover to close the molten metal reservoir and also supports a part of the mould 7. The plate 4 is pressed against a seal 5 by a piston and cylinder unit 11 and is locked in position by wedges (15) movable along guideways (14) in the plate and two of the columns 2, Fig. 2 (not shown). When the plate 4 is locked in position the piston and cylinder unit 11 is used to open and close the mould. If access to the reservoir 3 is required, the locking means is released and the plate 4 raised by the unit 11 until the end of the duct 12 is above the top edge of the reservoir 3. The reservoir 3, which is supported on wheels (19) via springs (22), may now be rolled out from under the mould. During a casting cycle the bottom of the reservoir is in contact with the end plate 1, but when the plate 4 has been raised the springs 22 cause the bottom of the reservoir to move up off the plate 1 and thus allow the reservoir to be rolled out.

Abstract: 1,143,056. Master cylinders; brake failure alarms. GENERAL MOTORS CORP. 7 Sept., 1967 [10 Oct., 1966], No. 40941/67. Headings F2E and F2F. [Also in Division H1]  A piston 180, Fig. 4 (or 80, Fig. 2, not shown) of a master cylinder is electrically insulated from the bore 36 in which it moves, and is electrically connected by a contact 214, loaded by a spring 216, to a terminal 228 connected to an alarm circuit which operates when a projection 222 on the piston engages the end wall 60 of the bore to complete the circuit. The alarm indicates failure of hydraulic pressure in the chamber 60 defined by the piston 180 and the bore 36, which chamber is connected to the rear brakes (20, Fig. 1, not shown) of a vehicle. The front brakes are operated by a second piston (54, Fig. 2, not shown), the master cylinder being the dual type having two reservoirs (38, 40). Failure of the front brakes causes the second piston (54) to approach the first against a return spring 68 which is stronger than the return spring 108 of the first piston. A contact member (124) on the end of the first piston ultimately engages the end (126) of the second piston (54) which is electrically connected to the cylinder body so that the alarm again operates. Electrical connection to the piston 180 (or 80) may be made, alternatively, by a resilient member (114, Fig. 3, not shown) which bears on the reduced diameter portion of the piston and is mounted in an insulating insert (26) in the cylinder wall. The piston 180 is insulated from the bore either by means of insulating piston rings (190, Fig. 4) made for example, of anodized aluminium, or by means of insulating spacers (92, 96, Fig. 2, not shown) separating the piston from non-insulating piston rings (90, 94).

Abstract: 1,127,363. Error correction. BUCHUNGSMASCHINENWERK KARL MARX STADT VEB. 28 Sept., 1965, No. 41155/65. Heading G4A. Calculations performed in an electronic programme controlled accounting machine with erroneous input numbers may be cancelled by depressing a key so that the calculations are repeated with the performances of predetermined marked instructions suitably modified. Thus a marked addition instruction would be repeated as a subtraction and vice versa whereby, for example, a running total which had had an incorrect quantity added into it could be returned to its previous value by having that same quantity subtracted. The marking is by means of a special bit in the order part of the instruction word. The modification of marked instructions may be terminated automatically by a program instruction. Figs. 2 and 3 (not shown) illustrate alternative arrangements whereby a flip-flop which controls whether addition or subtraction is performed is itself controlled by predetermined signal combinations.

In a cross-point switching arrangement, the operation of a number of control relays in a series circuit is prevented by connecting in series with each a voltage-dependent resistor such as a varistor or glow discharge tube which is insensitive to current direction and is such that its resistance is low provided the voltage exceeds a certain value. Thus, remanent relays can be used which are energized by a pulse in one direction and released by a pulse in the opposite direction. The relays may each control two cross-points, and further relays determine which of a pair is effective. The arrangement may be used in a path-seeking network such as that described in Specification 897,676.
