Title: Television clamping circuit
Inventor: JONES WILLIAM
IPC: H04N9/72
Filed: 1957-06-05
Abstract: 845,583. Television. PYE Ltd. Aug. 21, 1958 [June 5, 1957], No. 17895/57. Class 40(3). In an arrangement for clamping a television signal to a reference level during periods when a desired signal is present (e.g. during the occurrence of the colour burst in the NTSC colour signal) the clamping is controlled by pulses the repetition rate of which is the same as the frequency of the desired signal. Fig. 1 shows the application of the invention to the NTSC colour signal in a channel extending from video amplifier 1 to an output circuit 10 and including clamp circuits 3, 6 and 8. In accordance with the invention the colour burst is derived via a filter F and supplied via valve V gated on during the occurrence of the burst to a circuit 17 which produces two series of pulses of opposite polarity and these pulses are employed to clamp the burst signals in clamps 3, 6 and 8. When a monochrome television signal is supplied to amplifier 1, the clamp pulses from generator 16 (which gate valve V) are then effective to clamp the normal black level of the signal. The synchronizing signals present in the original television signal may be replaced by signals from a local source by operation of switch S.

Title: Photographic shutter
IPC: G03B9/14
Filed: 1962-05-15
Abstract: 998,487. Photographic shutters. AGFA A.G. May 15, 1962 [May 16,1961], No. 18724/62. Heading G2A. In a photographic shutter having two blades pivoted for simultaneous to and fro movement for opening and shutting, the means for transmitting the movement to said blades includes a crank mechanism for each blade comprising a rod connected between two pivoted crank members, and also connected at an intermediate point to the shutter blade. The form shown has two parallelogram linkages, one having linked members 4, 5, 6, 7 and the other having linked members 12,13, 14,15. Both linkage frameworks pivot on pins 2, 3 fixed to the camera housing. The two shutter bl des 20, 21 are symmetrically arranged with respect to the optical axis and the centre of the aperture 22. They are located by means of pins 23, 24 on the respective linkage bars 5, 7 of the outer framework, wnich pins enter into slots 25, 26 in the respective blades; pins 27, 28 on the linkage bars 13,15 of the inner framework enter into similar slots (not shown) in the blades. Each of the frameworks is loaded by a spring, 29 and 30 respectively. The shutter operating lever 35 pivots on a pin 36, and has at its end a swingle 39. On operating the lever in the direction 37, the swingle engages a pin 32 on the outer framework, and hence pivots the whole framework clockwise about its supporting pins 2, 3. An entraining lug 31 on this framework engages against the inner framework and pushes that also, so that the two frameworks pivot together, thus tensioning the driving springs. The inner framework has a projection 33 which can engage with a lever 34 forming part of a timing mechanism. Continued operation of lever 35 eventually brings the swingle clear of pin 32, so that the frameworks are released. The outer framework immediately moves back in the opposite direction, under the action of spring whereas the inner framework is retarded and held by the engagement of projection 33 with lever 34. This causes the blades to pivot to the "open" position. After the timing mechanism has run down, the inner framework is released to return to its original position, and the shutter blades close again. Specification 964,199 is referred to.

Title: Manufacture of pimelic acid
Inventor: HAWKINS EDWIN GEORGE EDWARD
IPC: C07C51/295
Filed: 1951-08-09
Abstract: A process for the manufacture of pimelic acid comprises contacting tetrahydrobenzaldehyde oxime in the liquid phase with an aqueous solution of an alkali metal hydroxide, the reaction mixture being heated to a temperature in the range 250-400 DEG  C. under elevated pressure.  The reaction occurs in two phases, ammonia being generated in the first and hydrogen in the second and both occur together when the above temperatures are used. Alternatively the first phase may be effected at a temperature in the range 80-250 DEG  C. and the temperature of the reaction mixture may then be raised, optionally after some separation of the ammonia, to complete the reaction.  The alkali metal hydroxide such as sodium or potassium hydroxide or a mixture thereof is preferably employed in excess.  In examples delta3-tetrahydrobenzaldehyde oxime is heated with aqueous sodium hydroxide in an autoclave.  The product is extracted with ether, the residue is acidified with hydrochloric acid and the pimelic acid is extracted with ether.

Abstract: 516,393. Correspondence control by electric motors; control of D.C. motors. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. June 25, 1938. No. 18884. [Class 38 (iii)] [Also in Group XXXVIII] In an electric servomotor system in which a motor effects a movement in correspondence with the movement of the means controlling the motor, the control means comprises an intermittent contact device in circuit with the motor and means for varying the relative duration of the make and break periods of the intermittent contact device. Motors 10, 11, driving respectively the wheels 12, 13. of a differential gear, have. in their field circuits resistances 21, 22, periodically short-circuited by conducting segments 24, 25, tapering in opposite directions on a commutator 23 and co-operating with brushes 27, 29, 30. The commutator 23, is driven by one of the motors, and the third element 15 of the differential is geared to a rod 19 connected with the driven device. Upon operation of a rod 33, a link 32 pivots about its lower end to move the brush 30 from its central position on the commutator 23. Thus the periods of shortcircuiting of the resistances 21, 22, are adjusted so that the motors 10, 11, operate at different speeds and the rod 19 is operated. The rod 19 is coupled to the link 32 and returns the brush 30 to give a follow-up action. In a modification, Fig. 2, not shown, contacts connected to ;the resistances 21, 22, are closed intermittently by a rotary cam driven by the motor 10, the position of the cam in relation to the contacts being adjustable by the link 32, to vary the relative make and break periods of the contacts.

In a fuel injection control device for an I. C. engine, the injection is effected in the form of a plurality of elementary injections, the number and duration of which are determined by a number of variables, e.g. temperature, pressure, speed, acceleration, of the engine. In one embodiment, a pick up 6, Fig. 7, delivers a signal to an electronic circuit when the crankshaft of the engine 8 passes through one or more given positions. The pick up may be an interruptor contact, photo-electric cell, magnetic pick up, variable capacitor, radio isotope detector or reed switch. The signal, after a delay controlled by input ma is fed to a monostable circuit 1, of the type shown in Figs. 1 or 2 (not shown), which converts it into a square wave pulse, which is transmitted after a time t 1 , controlled by the mechanical input ea which operates on variable resistor (R 1 ), to a circuit 2, of similar type. This delivers a square wave signal of duration t 2 , controlled by input d similarly controlling resistor R 2 ), to a circuit 3, of the type shown in Figs. 3-5 (not shown), which is a pulse generator or chopper. This circuit delivers a number of short pulses in time t 2 , whose number is controlled by input n controlling resistor (R 2 ), to a monostable circuit 4, of the type shown in Fig. 6 (not shown). This circuit includes a power transistor and delivers one square wave pulse of duration t 3 , controlled by input ed controlling resistor (R 3 ), for each of the input pulses, to a distributer 5. The distributer may take the form of a simple rotary contact, driven by the engine M, which successively delivers the power signals to the injection system of each cylinder.

In a synchronous dynamo-electric machine 10, e.g. generator, motor, condenser, or rotary converter, having stator and rotor members 11, 13 of which one, e.g. the stator, has an A.C. winding 12 and the other, e.g. the rotor, has a winding 16 disposed about an even number of discrete polar axes such that when D.C. energized the other member produces a like number of steady magnetic poles, the winding about at least some of the polar axes includes two separate windings 21, 22 which are wound in the same sense, have different resistances, and are connected or connectible in parallel to form closed loop circuits which act as induction motor secondary windings when the machine is started as an induction motor. As shown, the differing resistances result from the two windings having differing numbers of turns, but alternatively result from differing cross-sectional areas or specific resistances. Although shown on a salient pole rotor they may be alternatively on a cylindrical rotor, Fig. 7, or on the stator. Although shown as interleaved the windings may be partially or wholly axially spaced, Fig. 2, and the turns difference effected by an asymmetric crossconnection, Figs. 5, 6. In other modifications the parallel connection is made via slip rings by a switching means which thereby controls the torque speed characteristic.
