Title: Improvements in devices for cinematographic recording
IPC: H04N5/84
Filed: 1949-04-07
Abstract: 662,238. Television. TELE-INDUSTRIE. April 7, 1949 [April 10, 1948], No. 9530/49. Class 40 (iii). [Also in Group XX] A cinematographic system records preselected characteristics or portions of a television subject, such as colour components or picture zones, on separate film tracks. In Fig. 1, the lines corresponding to the segmental scanning of a subject, respectively for blue, red and green, are reproduced successively on lines a, b, c on cathode-ray tube screen 1 such that the blue component appears on line a, the red on line b and the green on line c. The visual output is then projected through optical system 2, 3, 4 on to continuously-moving monochromatic films 21, 31, 4<SP>1</SP>, and the films are partially masked so that only one of the images a<SP>1</SP>, b<SP>1</SP>, c<SP>1</SP> is recorded on each film. Thus image a<SP>1</SP> corresponding to the blue component acts only on film 41, whilst image b<SP>1</SP> corresponding to the red component acts only on film 3<SP>1</SP> and image c<SP>1</SP> corresponding to the green component acts only on film 21. The movement of the films is synchronized from the television synchronizing pulses and the speed is made such that every complete scanning of the televized subject corresponds to the recording of an elementary picture on each film. The films may be employed to reconstitute the original colour of the subject either during projection or by preliminary combination on a single film. The C.R. tube is provided with normal horizontal deflection and a step-wave generator synchronized from the television line pulses is employed to shift the beam between lines a, band c. In a further system, Fig. 2 (not shown), intended for faking purposes, three separate zones of a subject, such as the head, body and legs of a person, are reproduced on lines a, b, c, and recorded. In this case the axis y of the optical system is tilted to bring the images recorded on the films into any desired relative position.

IPC: B23Q15/00
Filed: 1950-04-19
Abstract: 682,617. Control of two motors. HERBERT, Ltd., A. July 4, 1951 [April 19, 1950], No. 9572/50. Class 38 (iii) [Also in Group XXII] A machine tool has a work-carrying slide driven by an electric motor which is arranged for reversecurrent braking upon the operation of a stop switch, the reversing operation continuing for a short period after the motor has come to rest so that the slide will actually reverse. The machine may have, in addition, a rotary cutter driven by a separate electric motor, and an overload switch, responsive to the current supply of the cutter motor or of the slide motor, may cause the slide motor to be braked and reversed in the manner referred to. Actuation of start button A connects relay B to an A.C. supply to close in turn a relay C which is controlled by time-delay contacts C1 and is effective during the starting and plugging of the cutter motor to cut out the overload switches. If a hand-operated reversing switch D is in the position shown a relay E is energised to close a contactor F for the cutter motor which then rotates forwardly. When the cutter motor reaches a predetermined speed contacts H1 on switch H close to complete a holding circuit for a relay G. Contacts C1 are then opened and contacts C4 closed to energise a forward contactor J for the slide motor. On the operation of overload switch K or L (responsive respectively to the current supply to the cutter or the slider motor) a tripping relay M is energised to de-energise contactor J. Contacts J2 open after a time delay so that a reverse contactor N is energised for a period which allows plugging and reversal of the slide motor. The cutter motor continues to operate. When a manual stop switch O is opened the relays B and E are de-energised to disconnect the cutter motor and relay C is energised to reverse the supply to the slide motor. After plugging of the slide motor contactors P and F are closed for reverse-current braking of the cutter motor. When the speed of the cutter motor falls to a pre-determined value contacts HI open to deenergise relay G, both motors then being disconnected,

Title: Improvements in or relating to the electrolytic coating of metals
IPC: C25D11/36
Filed: 1934-03-27
Abstract: 435,773. Electrolytic surface treatment of metals. GRAVELL, J. H., Elkins Park, Pennsylvania, U.S.A. March 27, 1934, No. 9614. Convention date, Dec. 11, 1933. [Class 41] Metals are provided with a protective coating by treatment as an electrode in a solution containing phosphate anions and metallic cations other than those of the alkali metals, the current being passed first in one direction, then in the other. The coating consists of a metallic phosphate which may in some cases contain a certain amount of free metal. The method is applicable to the coating of metals which are less noble than lead and are capable of forming water-insoluble phosphates, with the exception of aluminium. Such metals include iron, steel, manganese, zinc, cadmium, nickel, cobalt, chromium, tin and magnesium and their alloys. The method is not applicable to the coating of lead, copper, silver, gold or platinum. The cations contained in the electrolyte may be those of iron, zinc, cadmium, calcium, aluminium, nickel, cobalt and manganese. In addition to phosphates the electrolyte may contain sulphates, nitrates, nitrites, chlorides or arsenates. In an example, a ferrous metal is coated by the use of an electrolyte containing 0À150 lbs. of zinc oxide and 0À050 U.S.A. gallons of 75 per cent orthophosphoric acid and water to make 1 U.S.A. gallon, maintained at 160-200 F. Alternating current of commercial frequency such as 25-60 cycles and current density 25-50 amps. per sq. foot is passed until a coating of substantially maximum thickness is formed. The coated metal is then washed and dried. The treatment may be carried out in a steel or other metal vat which is connected as one of the electrodes. The vat becomes coated, but the coating when wet continues to act as a conductor. Alternatively, each of the electrodes may be constituted by the metal to be treated ; by the use of two phase or three-phase current, three articles may be simultaneously coated. Further examples of electrolytes containing iron, zinc and cadmium alone or in combination are given ; the coating produced from cadmiumcontaining baths contains some free cadmium. A nitrate or nitrite of an alkali metal, magnesium, cerium, iron or zinc may be added to the baths in amount not exceeding 0À04 lbs. per U.S.A. gallon as a depolarizer.

Title: Improvements relating to Furnace Retorts.
Inventor: SMITH CHARLES HOWARD
IPC: C10B7/02
Filed: 1919-04-17
Abstract: 126,614. Smith, C. H. May 9, 1918, [Convention date]. Retort furnaces; discharging.-Relates to "furnace retorts " or ovens more particularly adapted for the partial carbonization of coal, and comprises modifications in the setting and heating arrangements. in means for agitating and conveying the charge within the retort, and in the discharging-apparatus. The retort 2 is of inverted-heart shape in cross-section and is surrounded by combustion flues divided into two independently-controlied sets by longitudinal partitions 22, 23 below and above the retort respectively. Each fiue is independently fired, the gas being supplied from a main 33 through a valve-controlled pipe 34 for each flue, while the air from a recuperator enters through a port 30 controlled by a. vertically sliding damper 32. Combustion is effected in the flues around the retort, and the products escape through damper-controlled ports 36, 38 to a common longitudinal collecting-flue 40 for each set, passing thence through a downcast flue 45 to the waste-gas passages 13 of the recuperator. Adjustment of the gas and air supply valves and dampers is effected from a tunnel 10 beneath the retort and between the two recuperators. Layers of heat-insulating brick 35, 50, 51 are built into the setting at various parts to prevent loss of heat. When a number of retorts are built together in a battery, the abutting walls of the combustion zones of the setting are separated by an expansion space 49 and may be formed with offset portions to accommodate the downcast flues 45. The charge is fed into the retort bv a screw 53 and is conveyed therethrough by blades 56 on rotary shafts 54, 55 mounted in bearings 59, 60 supported indeper.- dently of the setting on platforms 62. The bearings are adjustable both vertically and horizontally, so that the position of the blades relatively to the retort may be varied, and each comprises a bed-plate 66 bolted to the platform, and a bearing-member secured thereto by vertical bolts passing through holes of larger size. On loosening these bolts, an horizontal or vertical adjustment can be effected by screws 74, 76. The bearing- member fits loosely into a casting 77, Fig. 14, built into the end wall of the setting, and a tight joint is made by a screw-pressed gland 64 and packing 65. The castings are formed with sightholes sh, and one of them has an opening with which registers the screw feed 53. The discharge passage 94 is divided by a vertical partition and leads to a drum-shaped casing 105 in which works an angularly movable or rotary valve 111. The casing is provided with an inspection cover, and from it depends a shoot 112 closed at the lower end by a door 118 and supported on a spring mounting.

Filed: 1944-05-22
Abstract: 620,297. Automatic temperature-control systems. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). May 22, 1944, No. 9819. [Class 38 (iv)] [Also in Group XXXVII] In a temperature-control system, current through the windings 35 of a relay (see Group XXXVII) passes also through a resistor 40 with a negative temperature coefficient. The resistor 40 is subject to the temperature to be controlled and when this, say, rises, the resultant increase of current through the windings 35 causes the windings 36 to be overpowered and the armature 26 to close contacts 27, 27<SP>1</SP>, thereby completing a circuit to a relay 49 controlling a motor 43 so that this moves and operates a shutter 42 to lower the temperature and also operates the arm 51 of a resistance switch so as to increase the current in windings 36. Eventually, owing to the temperature drop the armature 26 is restored to its mid-position. In a modification, the arm 51 is adjustable by hand and serves to determine the temperature that is maintained.
