Abstract: 405,289. Duplicating sound films. RADIO CORPORATION OF AMERICA, 570, Lexington Avenue, New York, U.S.A. July 29, 1932, No. 21489. Convention date, Jan. 13. [Class 40 (ii).] Copies of two sets of impressions disposed on a common carrier or on separate carriers are produced on a common carrier by simultaneously copying one set photographically with magnification other than unity, and the other set electro-optically. As shown, the combined sound and picture film 1 is fed through the picture gate 4 by an intermittent sprocket 5, and through the sound gate 7 at a uniform speed by a sprocket 8. The film 11 on which the copies are to be made is fed intermittently through the picture gate 14 by a sprocket 15 and through the sound gate 17 by a sprocket 18. The lamp 21, condenser 22, and projection lens 23 produce a reduced copy of the picture frame in the gate 4 on the film 11. The lamp 24, condenser 25, slit 26 and projection lens 25a produce a beam of light which is modulated by the sound record and which actuates a photoelectric cell 27 connected to an amplifier 28 provided with a gain control 31 and monitoring loud speaker 32. The amplified current actuates the vibrating mirror 29 of a recording galvanometer 30. Light from a lamp 33 passes through a condenser 34, a stop 35, and a lens 36, and is reflected by the mirror 29 through the lens 36 and the projection system 37 to form an image of the sound record on the film 1 upon the film 11 in the sound gate 17. The shaft 41 of the motor 40 carries bevel gears 42, 43 meshing respectively with bevel gears 44, 45 fixed to the shafts 46, 47.

Abstract: 1,227,921. Image reproduction. SYLVANIA ELECTRIC PRODUCTS Inc. 28 April, 1969 [26 April, 1968 (2); 4 June, 1968; 10 Sept., 1968], No. 21619/69. Addition to 1,226,804. Heading H4F. The specification is concerned with image reproduction systems of the type described in copending Specification 1,226,804 in which signals either from a television receiver 5, Fig. 1, or from a system 7 which develops electrical signals from photographic film, are selectively supplied to a picture tube 21. According to a first modification the system 7 includes D.C. restoration stages 43, 45, 47, Fig. 2, and gamma correction stages 73, 75, 77. The former stages are coupled to a potential reference level 57, a video signal source 33 obtaining signals from the photographic film 31 by means of a flying- spot scanner C.R.T. 29, and a source 55 of pulses which provide charge to capacitors 54 in the D.C. restoration stages to establish a uniform black level. The latter stages 81,83, 85 are coupled to the respective D.C. restoration stages 43, 45, 47 and to the potential reference level 57. An automatic brightness control facility may also be provided comprising a detector and amplifier circuit 91 which detects the amplitude of the D.C. restored video signals and supplies to the cathode of the scanner tube 29 a feedback signal for controlling the intensity of the light beam transmitted through a transparent film. The detector and amplifier circuit 91 includes a resistance network 95 which, in the form shown, adds the various video signals and applies them to the base of a transistor 93. Alternatively the brightness may be deduced from the green video signal alone. An alternative configuration of the circuit 91 is also disclosed (Fig. 3, not shown). The horizontal and vertical deflection coils associated with the scanner tube 29, Fig. 1, and the picture tube 21 may be connected respectively in parallel across the sources of the corresponding deflection control signals so that both tubes may be scanned synchronously. Suitable circuit arrangements to achieve this are illustrated in Figs. 4 and 5 (not shown). Fig. 6 shows an alternative system including an adapter network 11<SP>11</SP> whereby signals from the television receiver 13<SP>11</SP> or the film scanner 21<SP>11</SP> may be supplied to the picture tube 19<SP>11</SP>. The system includes a circuit 9<SP>11</SP> (illustrated in detail in Fig. 7, not shown) which provides scanning and control potentials to the scanner tube 21<SP>11</SP> synchronized to the operation of the picture tube 19<SP>11</SP> by means of synchronizing signals derived from the television receiver 13<SP>11</SP>. The circuit 9<SP>11</SP> also provides blanking signals to the adapter network 11<SP>11</SP> for selective application to the picture tube 19<SP>11</SP>.

Title: Improvements in and relating to the manufacture of liquid dispensers
IPC: B67D7/16
Filed: 1946-07-20
Abstract: 614,687. Coin-freed apparatus for dispensing liquids in measured quantities. COLEMAN, C. J. July 20, 1946, No. 21731. [Classes 27 and 106(v)] Apparatus for dispensing liquid in small quantities, such as fuel for mechanical lighters, comprises a rotary valve with a measuring cavity which can be turned manually, after a coin has been inserted to release a locking latch, from a normal position in which the cavity is charged from a reservoir, to a position in which it discharges its contents. The hollow conical plug valve 5 works in a bore in a block 2 which has a threaded socket 11 into which the neck of a bottle 12 of a lighter fuel is screwed. The bottle itself acts as the reservoir, and, in the normal position of the valve 5 a port 25 in it registers with a passage 15 leading to the socket 11 so that the hollow interior of the valve fills with fuel. On turning the valve anticlockwise by drawing down a handle 34, a second port 26 in the valve is brought into register with a discharge outlet 19 leading to a delivery spout 20 whilst the port 25 is brought into register with an air passage 23. The contents of the valve are thus discharged through the spout 20. To alter the amount delivered, the valve 5 is changed for another having a cavity 6 of different volume, or the valve is fitted with an end wall which is adjustable axially by means of an exterior screw to vary the effective capacity of the cavity. A liner 4 of cork or other elastic material is interposed between the valve and the bore in the block 2, and is lubricated by means of a film of castor oil and/or colloidal graphite. Coin action, weight.-Secured to a neck of the valve 5 is a coin pocket to which the handle 34 is attached, rotation of the pocket and valve being normally prevented by the engagement of the end 37 of a spring-actuated latch 38 pivoted at 40 under a step 39 in the pocket. An inserted coin falls down a chute 28 into the pocket and thrusts aside the catch 37 to release the pocket and valve which can then be turned by means of the handle 34. As the pocket turns, the coin moves away from the catch which holds it and falls into the lower part of the casing. The latch then relocks the pocket when the handle 34 is returned to refill the valve.

Abstract: 888,168. Jet flaps on aircraft. BATHURST, G. B. Oct. 9, 1958 [July 9, 1957], No. 21772/57. Class 4. A wing structure is provided with a mixing channel having an inlet and outlet at the leading and trailing edges of the wing respectively, and a series of injectors spaced apart and arranged to produce a series of jet sheets of primary gases within the channel, with which jets secondary air forced through the inlet into the channel upon forward motion of the wing, is caused to be entrained and mixed prior to passing out of the outlet in the form of a jet flap. The wing 1 has a chordwise duct 2 extending over the whole span with an air intake 3 and an outlet 4 positioned just forward of a rearwardly and downwardly curved surface 10. The upper wall of the duct carries a spanwise passage 5 which communicates with a gas turbine engine PJ and the dividing wall between the duct and the passage is formed with narrow slots 6 set at an angle # to a normal to the chord line when viewed along the span and at an angle α to a chord line so that the gas turbine efflux is omitted from the passage 5 into duct 2 in the form of inclined narrow jet sheets 9. Each slot is in close proximity to an aerofoil 7 extending between the upper and lower walls of duct 2 whereby the flow of air through duct 2 resulting from forward motion of the aircraft is caused to circulate round each aerofoil and mix freely with the respective jet sheet 9. The spanwise direction of discharge of the mixed gases from outlet 4 may be controlled by sets of adjustable vanes 8 and the gases in flowing over surface 10 adhere thereto by a Coanda effect to provide a jet flap.

Filed: 1975-05-21
Abstract: 1514322 Rotary head video tape recorders MATSUSHITA ELECTRIC INDUSTRIAL CO LTD 21 May 1975 [30 May 1974] 21782/75 Heading G5R In response to de-energisation of the tape drive motor 16 in a helical scan video magnetic tape recorder when a STOP button is operated, a control circuit applies a signal of predetermined duration to the motor 16 to cause reverse tape drive to thereby loosen the tape tension during the period that the rotary video head drum assembly (20) continues to rotate under its own inertia after operation of the STOP button. The loosening of the tape tension prevents the tape sticking to the head drum (20) when the transport is stopped, thereby ensuring smooth and stable restarting of the transport. A shaft (13), Fig. 1, belt-driven by the motor 16 carries an idler (12) movable along the shaft (13) for selective driving engagement with a tape take-up reel (10) or supply reel (11). During recording or playback motor 16 is energised from + and - power supply terminals via switches S1, S2 and rotates in a normal direction, a capacitor C1 charging via switch S3 from a power supply +B. When the STOP button is depressed or the power supply interrupted switches S to S4, which may be part of a relay assembly, move from the b to the c positions and the charge on capacitor C1 fires thyristor T1 after a delay determined by R1, R2 and C2, firing of T1 causing discharge of C1 through motor 16 so that the latter rotates in reverse to drive reel (10) or (11) in the direction to loosen the tape for a time period determined by the value of C1. An alternative circuit, Fig. 3 (not shown), uses an RC timing circuit (Rv), (C3) to turn on a Schmidt trigger (22) which causes a one-shot multivibrator (23) to turn on a transistor (T6) so that the motor 16 is driven in reverse for the period of the multivibrator to loosen the tape.
