Abstract: 1,182,904. Programmed control of machine tools. METABOWERKE KG CLOSS, RAUCH & SCHNIZLER. Nov.5, 1968, No.52450/68. Heading G3N. A programme control arrangement for machine tools comprises NOR-stores connected in accordance with successive programme steps and have their setting and clearing inputs inter-connected and their outputs linkable with the setting and clearing inputs of setting member stores. As shown, for each programme step 11-16 a NOR-store 17-22 comprising a pair of interconnected common-emitter transistor NOR-logic elements, and a switch 23-28 is provided. For the first step the switch 23 is connected to the NOR-store 17 through a NOR-store 30 and a monostable multi-vibrator 10, comprising four interconnected NOR logic elements. The outputs 36-41 of the stores 17-22 are interconnected by plugs connectors, not shown, with setting inputs 42 and clearing inputs 43 of stores 44 which are combined with amplifiers to control various setting members of the machine tool, such as couplings and hydraulic cylinders. The outputs of the stores 17-21 are also connected to the setting inputs of the following stores through limit switches 24-28 actuated by completion of a movement of a programme step, and the outputs of stores 18-21 also clear the preceding stores. A programme is initiated by depression of the switch 23 which sets store 30 and by a pulse from monostable multi-vibrator sets the store 17 which also clear the store 22. At the end of a programme the output of the store 22 clears store 30. The programme is stopped at any step by actuation of switch 52 which applies a signal to all clearing inputs 53.

In a first embodiment Fig. 1, an NTSC or PAL signal is fed via D.C. restoring amplifier 1 to processing circuits 100 and 200, the outputs of which are combined 17. In circuit 100 the lower frequencies are passed by filter 2 to an amplitude splitter 3 which directs the horizontal sync pulses via a variable gain amplifier 5 to an adder 4 and the luminance component directly to adder 4. The output of adder 4 is fed to mixer 17 and via a horizontal sync pulse sampler 6 to a differential amplifier which also receives a first reference voltage "Ref 1" and difference signal output of amplifier 7 is used to control amplifier 5. In circuit 200 the higher frequencies are passed by filter 8 to a gated amplifier 9 which directs the chroma component via amplifier 11 to an adder 12 and the burst components via a variable-gain amplifier 13 to adder 12. The output of adder 12 is fed to mixer 17 and via a detector 14 to a burst period sampler 15 whose output is compared with a second reference signal "Ref 2" in a differential amplifier 16, the output of which controls amplifier 13. For a S.E.C.A.M. signal the circuit 200, Fig. 2, comprises a filter 8 followed by a variable-gain amplifier 13 controlled by a signal derived via de-emphasis filter 18, detector 14, burst period sampler 15 and differential amplifier 16 receiving reference signal "Ref 2". A test pulse is preferably added to the thus processed composite signal in the vertical blanking period, and a circuit is described with reference to Fig. 4 (not shown) which directs an input composite signal via the processor of Fig. 1 or 2 and a test pulse inserting circuit, or via a correcting device when the input composite signal contains said test line.

Abstract: 1345740 Starting gas turbines B B C BROWN BOVERI & CO Ltd 18 Nov 1971 [20 Nov 1970] 53583/71 Heading H2H [Also in Division F1] Apparatus for starting a gas turbine 1 driving a synchronous generator 2 comprises a diesel engine 7 driving a synchronous generator 6 which, via switch 11 activates an induction motor 5 which drives an induction generator 4 having a stator winding connected to a stator winding of the generator 2, the ratio of the synchronous speeds of the generator 4 and motor 5 varying as the ratio of the output frequency of the generator 2 in normal operation and 1/60 times the product of the number of pole pairs of the generator 2 and the speed of the turbine at and above which the turbine is able to supply an accelerating torque. In operation if the mains is not available the motor 7 is started to drive the generator 6 and bring the motor 5 up to speed. The switch 8 is closed to develop an electrical connection between the stators of generators 4 and 2 and the latter is rotated slowly by a motor 3 which may derive power from the generator 6 and which is also employed for driving machine 2 at a slow speed during cooling down. The stator winding of machine 2 will thereby have a voltage induced therein of a frequency proportional to its rotational speed which will drive a corresponding current through the stator of generator 4 and generate a rotating field therein. Thus the rotor at 4 operates at a super-synchronous speed relative to its rotating field and under these conditions a part of the mechanical power delivered by the motor 5 will be available to accelerate the generator 2 and turbine 1 which is then accelerated to the applied frequency which is above the required speed so that the turbine may deliver a further accelerating torque to drive the generator 2 at its operational speed. The output of machine 2 may be connected via 9 to the mains. If the mains is live during the starting up procedure the motor 5 may be operated directly through switch 10.

Abstract: 1364539 Brake transmitting mechanism; over-run and hand actuation KOBER MANPAR AG 23 Nov 1971 [27 Nov 1970 12 Feb 1971] 54411/71 Heading F2E An actuating device for an over-running trailer brake, such brake being preferably as described and claimed in Specification 1,364,540, divided from the present Specification, comprises a hand-brake lever, an over-running selector device, and linkages connecting the hand-brake lever and selector device to a common joint which is connectible to the mechanically-actuated expanding device of the brake, the linkage connecting the hand-brake lever to the common joint including a compression spring, and the hand-brake lever being capable of sufficient swivelling movement to cause further displacement of the common joint after displacement of the common joint by the overrunning selector device. As shown, a pull rod or plunger 35, longitudinally displaceable in a housing 36, acts on a reversing lever 37 pivotable at 38 in the housing. Linked to the reversing lever 37 is linkage 39  (a stirrup of U-section) provided with a hinge bolt 40 to which a brake-operating cable 41 is attached. A hand brake lever 44 is also pivoted at 38. A rod 48 is slidable in a bolt 46 on the lower arm of hand brake lever 44, and engages, by a head 50, a spring 49 whose other end is engaged by a restriction 51 of a casing 47 (these parts constituting another linkage). In operation, on over-running of the trailer, pull rod 35 moves to the right relative to housing 36, so lever 37 is swivelled clockwise, thereby applying the trailer brakes. The connection between handbrake lever 44 and the brakes is not affected, so the lever remains in the position shown in full lines in Fig. 6 (because bolt 40, which extends through casing 47, pushes the casing and rod 48 to the left, but rod 48 slides through bolt 46). The same sequence occurs when the trailer is reversed by the towing vehicle, but for reasons given in the Specification the trailer brakes are not then applied. When the handbrake lever 44 is rotated, rod 48 is entrained by nut 46 (via head 52), spring 49 is compressed, and the brakes are applied via casing 47 and hinge bolt 40. Simultaneously linkage 39 is moved by bolt 40, and in turn, lever 37 is swivelled clockwise, coming away from pull rod 35. Hand-braking of reversed trailer. - When the trailer has been reversed and the over-running device has moved the linkages, without applying the brakes, to the positions described in an earlier paragraph, the handbrake lever (which has an exceptional range of movement), on being rotated to its limit position shown dotted in Fig. 6, is able to entrain rod 48 and move it still further to the left. The ensuing extra movement imparted to cable 41 serves to apply the brakes, when the brakes are such as have been referred to earlier.

Blocks of digital data, e.g. share quotations, are received on a shift register from which selected blocks are passed to a recorder. In the system described a tape or keyboard transmitter generates quotations comprising three share identity characters, of which the first and last must be letters, and characters indicating the share price. The characters are in 6-bit Start Stop code, a shift bit indicating letters or figures. A mechanical distributer passes the signals serially to the receiver, where they are distributed to the relays in a four-character shift register. When the shift bit in the third stage indicates the presence of a letter character and that in the fourth stage a figure character the content of the first three stages is compared with a preselected combination, set up by interconnection of additional contacts on the relays so that an output pulse is given only when a preselected share identity is detected. This pulse sets in operation a mechanical distributer which passes the share identity, and subsequently received signals, to a printer or perforator. This distributer is stopped when a letter character from the next quotation appears in the last stage of the register, unless this quotation, too, is a preselected one.
