Title: Improvements relating to telecine apparatus capable of recording television signals upon film
Inventor: MCKEE KENNETH MACINTOSH
IPC: H04N5/84
Filed: 1951-11-28
Abstract: 720,185. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Oct. 15, 1952 [Nov. 28, 1951], No. 27852/51. Class 40 (3). In an arrangement for recording on moving films a plurality of images with discontinuities between successive images (e.g. images on a further kinematographic film) successive areas of the film on which the record is to be made are exposed to images reconstituted from television signals produced by interlaced scanning of the images to be recorded and the latter scanning is so synchronized with the exposure of the film on which the record is to be made that each area of this film is exposed only during the fields generated by the scanning of a single one of the images to be recorded. As shown in Fig. 1, television signals representative of successive frames of a continuously moving film 11 generated in a photo-electric device 27 (by interlaced scanning with a " flying-spot " scanner 1 and co-operating double lenses 23, 24 and rotating shutter 14) are reconstituted by a picture reproducing tube 1a and directed via a similar lens and shutter arrangement 23a, 24a and 14a on to a second film 11a on which the images are to be recorded. The relative position of both shutters in relation to the positions in the film gates 13, 13a of their respective films is initially arranged such that each area of film 11a has recorded on it the component fields derived by scanning a single frame of film 11. This is effected by arranging that when a film frame bar 21 occupies a central position in gate aperture 13, one of the shutter vanes is in a position to obturate the image of the " flying- spot " raster projected on to the lower half of 13 by the lens 24. To maintain these relative positions throughout the duration of the scanning and recording operation the speed of the motors 17, 17a driving the film sprockets and the shutters is controlled by the output from discriminators 36, 36a in which the phase of signals produced by multivibrators 35, 35a under the control respectively of generators 34, 34a coupled to the shutter driving shaft is compared with the phase of signals produced by further multivibrators 33, 33a under the control of pulses occurring during alternate scanning fields and produced in unit 30. In an application of the invention to making film records by recording television signals derived selectively from different picture signal generating devices change-over from one device to another is so controlled by the synchronizing signals of the system that it can only occur in intervals between the exposure of successive areas of the film employed in the recording device, Fig. 3 (not shown).

Filed: 1920-10-04
Abstract: 151,992. Metropolitan-Vickers Electrical Co., (Assignees of Staege, S. A.). Oct. 2, 1919, [Convention date]. Motor running synchronously with a source of constant frequency; systems depending on use of two or more motors.-A constant speed ratio is maintained between two or more electric motors of a paper mill by providing each motor with a controller the operation of which is dependent upon the frequency of an alternating current, which frequency is proportional to the speed of the motor, and upon a standard-frequency alternating current. The speed of the motors may be varied, without altering the ratio, by varying the excitation of the generator supplying them, and the standard frequency may be varied by varying the speed of the machine supplying it. A motor 5, Fig. 1, drives a roll 1 and the winding 17 of a frequency-changer 15, the primary winding 16 of which is energized from the mains 28, 29 and 30. The winding 17 is connected to the primary winding 36 of a motor 14, the secondary winding 37 of which is connected to the secondary winding 33 of a frequency-changer 31. The primary winding 32 of the frequency-changer 31 is connected to the mains 28, 29, 30, and the secondary winding 33 is driven by a motor 35 to produce the standard frequency. Under normal conditions the frequencies of the currents supplied to the windings 36, 37 of the motor 14 are equal ana the rotor is at rest. Upon a variation of the speed of the roll 1, the frequency of the current supplied to the winding 36 is varied and the motor 14 operates to move, through a friction clutch, the contact-arm 38 of a relay 49. According to the direction of the variation of the speed of the roll 1, the conftact 39 engages contacts 40 or 41 to control the direction of rotation of a reversible motor 42 which operates a rheostat 11 in the field circuit 10 of the motor 5 driving the roll 1. To prevent hunting of the rheostat 11, the arm 38 is oscillated when in either of its operative positions by means of solenoids 50, 51 which are energized periodically from a battery 52 through a motordriven interrupter 53. The speed of a motor 6 driving a roll 2 is controlled similarly by means of a motor 61 and a rheostat which is not shown. In the modification shown in Fig. 2, the ratio between the speeds of the rolls 1, 2 is maintained constant by varying the excitation of the motor 5 when the ratio varies, and a similar arrangement may be provided to maintain the speed ratio between the roll 2 and another roll (not shown). The motor 5 drives a frequency-changer 15, the secondary winding 17 of which is connected to the winding 81 of a motor 80. The motor 6 drives a frequency changer 18, the secondary winding 20 of which is connected to the winding 82 of the motor 80. When the speed ratio between the rolls 1, 2 varies, the motor 80 operates to control a rheostat as described in connexion with the arrangement shown in Fig. 1. The motor 14, Fig. 1, and the motor 80, Fig. 2, may operate the rheostat 11 directly.

Abstract: 966,885. Measuring temperature electrically. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 23, 1962 [Aug. 3, 1961], No. 28184/61. Heading G1N. [Also in Division H4] Conventional thermocouple means are employed to measure the temperature of a nuclear fuel element with respect to a reference point the temperature of which is measured by means involving the resonant frequency of an electromechanical vibrating element loaded by a fluid (gas) at the latter temperature. The vibrating element comprises an iron armature 33 (Fig. 1) energized by an electromagnet 26, 27 the whole being encased in an helium filled capsule 23 retained in a cavity in the end fitting 21 of a nuclear fuel element 11. The armature 33 is carried by a diaphragm 31 provided with an aperture 34 to equalise the gas pressure on each side and in the space above the diaphragm is supported the "cold" junction 35 of four (one only shown) thermocouples each of which is connected by a cable 36 to respective "hot" junctions 37 (two only shown) embedded in the surface of the fuel element. The thermocouple junctions are connected in a series arrangement including the coil 27 of the electromagnet 27 to an output cable 38. In operation, an oscillator 41 (Fig. 3) of adjustable frequency, energizes the system via a detector 42 connected to an indicator 45 the reading of which rises to a maximum when the oscillator is operating at the resonant frequency of the vibrating element. The temperature of the capsule 23 (reference temperature) is then deduced by known means from this resonant frequency. The temperature of the fuel element is then measured by adding to the reference temperature the temperature read on indicator 47 derived from the thermocouples by means of a high impedance D.C. amplifier 46 provided with filters to block the A.C. energy from oscillator 41. Instead of utilizing a vibrating diaphragm the vibrating element may comprise an acoustic resonator such as an organ pipe, a Helmholtz resonator or a whistle resonator. Specification 966, 884 is referred to.
