Title: Improvements in and relating to pulse generators
IPC: H03L7/24
Filed: 1959-11-20
Abstract: 865,298. Electrical digital data storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 20,1959 [Nov. 20, 1958], No. 39438/59. Class 106 (1). A clock comprises mono-stable trigger circuits MV61 to MV63, of which MV61 and MV62 are connected to form a multivibrator providing the normal clock period and MV63 acts in response to data signals to bring data and clock signals in phase. Each trigger circuit provides a positive voltage output when off and a negative voltage output when on, MV61 on line 79, MV62 on line 93 and MV63 on line 98 and inverted on line 99. A clock run signal is applied to AND circuit 20 together with positive signals derived from MV62 and MV63 to initiate a 12-microsecond clock period, the first 6 microseconds of which are occupied in charging the capacitor 51 of MV61, a negative signal appearing on lines 79 and 80 to output OR circuit 81 which provides an inverted signal on line 83. When the capacitor is charged a positive signal issues on lines 79<SP>1</SP>, 79 and is applied to AND circuit 201 together with a positive signal from MV63, and to the output OR circuit. AND circuit 20<SP>1</SP> is operated and capacitor 51 of MV62 is charged, issuing a negative signal on lines 93, 72, disabling AND circuit 20. At the end of 6 microseconds line 93 becomes positive and AND circuit 20 is enabled. Data signals are applied at input line 60 of AND circuit 201, and if such a signal is early (t<SP>1</SP>, Fig. 6) will initiate charging of capacitor 51 of MV63, the resultant negative signal on line 98 preventing the turning on of MV62. The positive signal on line 99 is applied through a delay device 102 to AND circuit 20 so that MV61 is not turned on before MV62. Thus the space of 6 microseconds is diminished. If the data signal is late, MV61 already being on, MV63 is operated and its output on line 98 is applied to output OR circuit 81 to increase the mark of 6 microseconds as necessary. Then MV62 is turned on to provide the normal 6 microsecond space. The circuits indicated in Fig. 1 use junction transistors and are fully described.

In a facsimile apparatus wherein a picture to be transmitted is moved past a slot 3, Fig. 1, in a plate 2 by a roller 1, and horizontal scanning is effected by the movement of holes 10 in a tape 11, the speeds of the roller 1 and the tape 11 are measured by a tachometer 23, and a photo-electric arrangement wherein light from a source 20 passes through holes 22 in the tape on to a photo-cell 21, respectively, and the frequencies thus developed are compared with a standard frequency to control a servomechanism 24 and thus maintain the two speeds constant. A complete line across the copy is illuminated by light source 4 and the image of the entire line is projected through focusing lens 5 and condensing lens system 6 to mirrors 7 and 8 and hence to photo multiplier 9. The drive and idler pulleys for the tape are smooth and the rectangular holes 22 are said to give a good sine wave when the beam has a circular cross-section. The standard frequence may be obtained from a temperature controlled tuning fork or piezo-electric crystal and the frequencies are compared in a two-anode tube in which the sheet beam is deflected by a pair of electrodes to which the standard and measured frequencies are fed. The control loops include a pilot motor driving an arm over a precision potentiometer and an integrating network. Examples of suitable frequencies are given.

Abstract: 937,567. Centralized position - indicating arrangements. STANDARD TELEPHONES & CABLES Ltd. Nov. 3. 1961 [Nov. 9, 1960], No. 39457/61. Class 118. [Also in Groups XX and XL (c)] A system for displaying in formation in three dimensions in space comprises a flat display surface which is rotatable about an axis in its plane, means for directing imageforming radiation on to a predetermined area of this surface and control means for moving said area in accordance with the information to be displayed. In the air traffic display system shown, a translucent display screen 1 is rotated by motor 2 at a constant speed high enough for it to be imperceptible by an observer. By means of a lens 6 and mirrors 3a, 3b which rotate with screen 1, there are projected thereon from C.R.T. 5, lightspots at positions, corresponding to the altitude and distance of an aircraft, whenever the instantaneous angular position of screen 1 corresponds to the aircraft's bearing. For this purpose, analogue signals proportional to altitude, distance and bearing are fed to C.R.T. 5 from sources 10a, 10b, 10c, the bearing signal from 10c being compared at 9 with a signal derived from a potentiometer 7 that is adjusted as screen 1 rotates so that a pulse is supplied to the electron gun 5f of the C.R.T. only when the angular position of screen 1 corresponds to the aircraft's bearing. Co-ordination by the C.R.T. beam deflection with the rotation of screen 1 may be obtained by rotating the C.R.T. 5 by motor 2 and gear 5, in which case the information signals are fed in through brushes 5c, 5d and 5e. In this way, light spots 14a, 14b ... 14n repre. senting aircraft in the vicinity of an airport 13 will be displayed as in Fig. 2. The position of any of these aircraft may be determined from the display by using a screen 1 that has coordinate lines etched thereon and employing a stroboscopic light to " stop " the rotating screen. A colour wheel may be disposed between C.R.T. 5 and screen 1 so that the light spots may be differently coloured.

Title: Nitriles and amides of pyridine carboxylic acids
Filed: 1956-12-31
Abstract: Pyridine carboxylic acid nitriles are prepared by passing a fluid stream consisting of or comprising vapours of the corresponding acid amide over a dehydration catalyst at a temperature ranging from 250 DEG  to 550 DEG  C.  The nitriles may be hydrolysed to obtain purified amides substantially free of both colour and pyridine carboxylic acid.  The dehydration catalyst is preferably silica gel, alumina gel or mixtures thereof.  The vapours of the amide may be admixed with a non-condensible gas such as nitrogen or ammonia.  The process is applicable to the purification of pyridine carboxylic acid amides containing minor amounts of the corresponding free acid, e.g. a niacinamide melt containing residual niacin (which may be prepared by passing ammonia through niacin and heating the mass to form a melt).  The examples describe the preparation of nicotinonitrile, isonicotinonitrile and purified niacinamide.

Abstract: 979,482. Control of several D.C. motors. HAGGLUND & SONER A.B. Nov. 7, 1961, No. 39766/61. Heading H2J. [Also in Division G3] An electric tram is driven by motors 1-4 fed from a supply line L through a circuit including an overload current breaker M, a differential relay D, a switch V for changing the motors from driving to braking, a control resistance W and a coil 10 of an electromechanical brake P which is disengaged by the energization of the coil when the motors are driving the wheels. The control resistance W is switched to vary its total resistance by contactors K controlled by a computer R which derives its control current via a control lead C from a drive control element F or a braking control element B, located at the driver's position. The control current is also influenced by a shedding detector S responsive to the output of tachogenerators T. During braking the change-over switch U is controlled automatically, the motors 1-4 acting as generators feeding resistance W, acting as a load, the brake P becomes operative with the reduction in motor current. The desired acceleration or deceleration is set by the adjustment of resistor 12 or 14 by elements F or B and the appropriate actuation of contactors K is determined by the computer R which comprises an accurate reproduction on a reduced scale, or a model, of the control resistance W which is fed during driving from a voltage m derived from a voltage drop across the resistance W and during braking by a voltage d corresponding to the wheel speed from the device S; stepwise connection of the resistances in the model is effected until equilibrium is reached between the control current and the model resistance current, the corresponding contactors K are then actuated. It is stated that the computer stepwise connections can be effected by high speed relays or transistors and diodes. Trailer vehicles are connected to the driver's controls by a connection A.

Abstract: 924,643. Transistor multi-stable circuits. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. March 11, 1960 [Dec. 11, 1958], No. 39973/58. Class 40 (6). [Also in Group XIX] An electronic counting chain comprises a plurality of bi-stable cross-coupled transistor pair stages, all normally in a second state, except one which is in a first state, the switching of the stage in the first state to the second state causing the next stage to switch from the second to the first state. As described, a ring counter comprises a plurality of bi-stable stages supplied with stepping pulse alternately on two lines S1, S2 of which three stages, A, B and C, are shown. All the stages except one are in a second state, with the transistor TR1 conducting and the transistor TR2 cut off. Assuming that the stage A has been switched to the first state, with the transistor TR2A conducting, the next stepping pulse, which is on the line S2, switches the stage A to the second state, thereby producing an output pulse over a capacitor C1, which pulse is effective to switch the stage B to the first state.

Filed: 1964-10-01
Abstract: 1, 021, 414. Numerical control of machine tools. MASCHINENFABRIK HEID A.G. Oct. 1, 1964 [Oct. 1, 1963], No. 40007/64. Heading G3N. In a numerical control system for a machine tool, travel data is programmed in incremental steps, or, where the desired position is to be of greater accuracy than that afforded by the travel indicator, by the selection of rigid stop members. As shown, travel and circuit data read by a perforated strip scanner 1 is fed to a control unit 3. Directional data is fed to a positioning member 5 for a carriage 22 and desired travel data, through a store 7, is applied to a comparator 9. Carriage movement is sensed by an indicator 10 sending increment pulses to a backward and forward counter 12 supplying actual travel data to the comparator 9. At coincidence between the desired and actual travels a signal is sent through a switch 15, conditioned by unit 3, to the unit 3 to stop positioning member 5 and step the scanner 1. When a travel position is required to be of higher accuracy than that attainable by the incremental system, the scanner 1 conditions the control unit 3 so as to change-over switch 15 so that the travel terminating signal is derived from a rigid stop member 21. For automatic zero-positioning a coincidence signal from the member 21, through a delay device 32, zeros the counter 12. The rigid stop member 21 incorporates a pair of switches the first of which reduces the speed of a positioning motor and the torque of a driving clutch, the second switch open-circuits the clutch when the carriage 22 strikes the rigid stop member.
