Title: Improved circuit-arrangement for use in a television receiver
IPC: H04N5/10
Filed: 1952-03-13
Abstract: 699,999. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 13, 1952 [March 16, 1951], No. 6577/52. Class 40 (iii). [Also in Group XL (c)] A circuit arrangement derives a sinusoidal voltage at line frequency from the incoming combined television synchronizing pulse train by utilizing the derived voltage to render the circuit unresponse to all pulses except those recurring at line frequency. In Fig. 1 the synchronizing pulses 3 are separated from the video signals 2 by peak detection at the grid of valve B1 and are differentiated in the anode circuit L1, C1, R1 before application to the grid of valve B2 by coupling inductor L2. A resonant circuit K in the anode of valve B2 is tuned to line frequency and a sinusoidal voltage is derived at terminal 16. Inductor L3 is coupled to circuit K and injects a sinusoidal voltage in series with the differentiated pulses from coil L2 whereby the voltage appearing at the grid of valve B2 takes the form shown at V in Fig. 2. In this Figure, V1 represents the combined synchronizing pulse train comprising line pulses 4, frame pulse 6 interrupted at twice line frequency by pulses 7 and 8, and equalizing pulses 5. Grid circuit C2, R2 biases valve B2 beyond cut-off level 11 so that the valve only becomes conducting for pulses, such as 12 and 15, corresponding to the leading edges of pulses at line frequency and remains non- conducting for all other pulses. In the arrangement shown in Fig. 1, failure of the synchronizing pulses allows the bias due to circuit C2, R2 to fall until the valve conducts on the peaks of the sinusoidal voltage and functions as an oscillator. In an alternative embodiment, Fig. 3 (not shown), a diode in the grid circuit prevents the valve conducting so that the sinusoidal voltage ceases with the synchronizing pulses.

Abstract: 419,915. Photographic cameras combined with telemeters. ZEISS IKON AKT.-GES., 72, Schandauerstrasse, Dresden, Germany. March 1, 1934, No. 6606. Convention date, Sept. 21, 1933. [Classes 97 (i) and 98 (i).] The objective adjustment of a photographic camera is coupled with a telemeter, the raydeviating means of which consists of two spherical or cylindrical lenses of opposite sign mounted so as to be relatively rotatable about an axis perpendicular to the plane of measurement and producing zero deviation of the rays in the infinity position. Provision may be made to rotate the lenses about a second axis at right angles to the first to compensate for vertical errors. In the form shown, the objective mount 2 is screw-threaded for axial adjustment and drives a rack 13 through gearing 10, 11, 12. The rack 13 is connected to the support of a plano-convex lens 4 through a rod 14 working in a correction curve 16. The support is pivoted to the camera and a planoconcave lens 3 is mounted in front of the lens 4. The adjustment is effected by a wheel 17. The base of the telemeter is constituted by a rhombic prism 5 having reflecting surfaces 6, 7, the surface 7 being semi-transparent and having a prism 8 cemented thereto.

Title: Spray gun
IPC: B05B1/30
Filed: 1961-02-23
Abstract: 933,706. Spray-producers. SPEE-FLO MANUFACTURING CORPORATION. Feb. 23, 1961 [March 1, 1960], No. 6735/61. Class 69 (3). An airless spray gun which hydraulically atomizes paint and other liquids has a passage 14 supplied with paint under pressure via a swivel coupling 21 and strainer 19, and when a valve stem 27 is retracted by a trigger 35 the paint flows through a bore 25 and issues from a restricted orifice 43, Fig. 2. The paint flows from the orifice 43 as a jet which is submerged in the paint filling the space between that orifice and the inlet of a coaxial bore 50 in a spray tip 46. Paint enters the spray tip 46 at a considerably lower pressure and considerably higher velocity than those subsisting in the bore 25 and is such that the pressure drop and consequent acceleration through the nozzle opening 61 are not great enough to produce an appreciable " vena contracta," and the spray spreads uniformly away from the nozzle opening. The latter is located in a boss 55, and is formed by a transverse tapered slot 59 which cuts across the spherically-shaped end of the bore 50 to provide an oval-shaped outlet 61 having its long dimension equal to the diameter of the bore 50 and a short dimension equal to the minimum width of the tapered slot 59. A spray of fan-shaped cross-section is thereby provided. In the embodiment of Fig. 6 the restricted orifice 143 is located in a separate plate 170; in Fig. 7 the restricted orifice 243 is located in a part 271 protruding from a disc 270 and engaging within the nozzle tip 246. In the modification of Fig. 8 a restricted orifice is not provided, and the paint issues as a submerged jet from a bore 341, and the pressure therein is restricted to atmosphere by removing excess paint via passages 373, 375 and hose 376 which is connected to the input of a pump. The spray tips such as 37, Fig. 1, of the guns described may be replaced by others with orifices 43 of different sizes.

Abstract: 668,000. Multiplex radio signaling. FAXIMILE, Inc. March 17, 1950 [March 31, 1949], No. 6747/50. Drawings to Specification. Class 40 (v). Facsimile telegraph and sound signals are transmitted by amplitude modulating a superaudible subcarrier with the facsimile signal and frequency modulating the transmitted carrier with the sound signal and the modulated subcarrier, the latter being arranged to produce not more than one-tenth the maximum deviation produced by the sound signal and having no common path with the sound signal through any non-linear amplifier. As described, the subcarrier frequency is 35 kc/s. and the lower sideband 22 to 28 kc/s., produced by the facsimile signal, is used to modulate the transmitter, this sideband being selected at the output of the receiver discriminator by a band-pass filter, and demodulated to provide the signal for the facsimile reproducer.

IPC: H02M7/62
Filed: 1927-03-11
Abstract: 289,602. Coventry Automatic Telephones, Ltd., and Collyer, J. E. March 11,1927. Electromagnetic interrupters.-An alternating or pulsating current is obtained from a direct current source by means of a vibrating interrupter, the vibrating member 8 of which is normally maintained under strain, for example by an electromagnet 4, and is released to vibrate at its natural frequency without further energiza.- tion during the period in which current is required. The vibrating member cooperates with contacts 10, 13 to energize the primary winding 18 of a transformer from a battery connected between the mid point of the winding and the vibrating member. The secondary winding 19 may be used for supplying ring- ing current to small telephone exchanges, in which case the electromagnet 4 is controlled by contacts 17 operated periodically by a relay forming part of a relay chain, or by a revolving cam.

Abstract: 525,968. Wireless receiving systems. KOLSTER-BRANDES, Ltd., and SMYTH, C. N. March 3, 1939, No. 7086. [Class 40 (v)] The local oscillator section of a triode-hexode or heptode valve of. a superheterodyne receiver for ordinary broadcast programmes is used also for television reception, switches being provided to change over the oscillatory circuits to provide the different heterodyning frequencies for the two purposes. With the switches S1 ... S5 in the positions shown, the circuit is arranged for ordinary broadcast reception and comprises a frequency-changing triode-hexode V1 feeding an intermediate-frequency amplifier V2 and detector V3 through tuned circuits IF1, IF2. For television reception, the ganged switches S1 ... S5 are changed over, substituting the localoscillator tuned circuit OSC2 for circuit OSC1 and feeding the higher-frequency local oscillations over condenser C1 to the television frequencychanger V4. The vision and the accompanying sound intermediate frequencies are separated in circuits IF4, IF5, the sound being fed to amplifier V2 and over a substituted tuned circuit IF3 to the detector V3. Automatic volume control potentials are obtained from diode D2 for the broadcast reception but not for the television since there is no feed to D2 in the latter case.
