Title: Improvements relating to direct-current supplies for output valves feeding high-frequency furnaces
IPC: H05B6/06
Filed: 1959-11-30
Abstract: 897,345. Protective cut-out arrangements. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 30, 1959 [Dec. 3, 1958], No. 40597/59. Class 38 (5). [Also in Groups XXXV and XL (c)] A protective arrangement for a rectifier comprises overload relays B, C whose responsecurrent can be adjusted by means of resistors 52, 53. Initially the grids of thyratrons 37-39 are negatively biased so that no current flows through relay B and the converter operates as a half-wave rectifier protected by relay C. When the thyratrons are made to conduct, no current flows through relay C and the converter operates as a full-wave rectifier protected by relay B. Operation of a relay causes contacts b or c to open and relay A to be de-energized, which causes the feed transformer to be disconnected from the input. Specification 716,891 is referred to.

Title: Light beam scanning systems
IPC: H03K17/78
Filed: 1966-09-12
Abstract: 1,103,910. Deflecting light; semi-conductor pulse circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. 12 Sept., 1966 [13 Dec., 1965], No. 40613/66. Headings H3T and H4F. A beam of plane polarized light from a digital light deflector comprising electro-optic devices 20, 50 and 80, Fig. 1, controlled by circuits 28, 58 and 88 respectively and birefringent crystals 22, 52 and 82, is arranged to automatically scan in repetitive sequence the output positions " 0 "-" 7," by sensing the output position of the light beam and using the resulting signals to control the circuits 28, 58 and 88. Each electro-optic device comprises an electro-optic crystal between a pair of transparent electrodes and is such that if a half wavelength voltage is applied across the electrodes the axis of polarization of the light beam is changed by 90 degrees and thus passes through the birefringent crystals as an extraordinary ray and is deflected. The control circuits 28, 58, and 88 which charge and discharge the electro-optic devices each include a tank capacitor 32 connected to one of the transparent electrodes through an inductance 30, diodes 34 and 36 being arranged at each end of the inductance to block the flow of current towards the inductance, these diodes being by-passed by silicon-controlled rectifiers 38 and 40. The light beam emerging from crystal 82 in any one of the eight positions impinges on a beam splitter 106 which deflects a portion of the light towards light-sensitive diodes 108- 122. These diodes are each connected in a separate series circuit with an amplifier or switch 124 between the positive terminal 126 and the gating terminal of one of the siliconcontrolled rectifiers. The particular silicon-controlled rectifier is indicated at the terminal 128 of each of the series circuits. Initially all three electro-optic devices 20, 50, 80 are discharged and the light beam emerges in " 0 " output position causing diode 122 to conduct which provides a positive output to the gate of rectifier 40 causing it to conduct. When rectifier 40 conducts device 20 is charged and the light beam is deflected from output position " 0 " to output position " 7." The light beam in output position " 7 " impinges on diode 108 causing it to conduct and bias rectifier 100 conductive. This charges device 80 so that both electrooptic devices 20 and 80 are charged and the light beam is deflected from output position " 7 " into output position " 6." The light beam is thus deflected from position to position in a repeating sequence, the electro-optic devices being charged and discharged as tabulated in Fig. 2 (not shown). The silicon-controlled rectifiers and light-sensitive diodes may be replaced by light-activated silicon-controlled rectifiers, Fig. 3 (not shown).

Title: Circuit arrangement for a relay operating an automatic station-search drive in television or broadcasting sets
IPC: H03J1/18
Filed: 1963-10-18
Abstract: 1,047,587. Automatic tuning arrangements. STANDARD TELEPHONES & CABLES Ltd. Oct. 18, 1963 [Oct. 19, 1962], No. 41238/63. Heading H3Q. An automatic tuning arrangement is controlled by a relay which in its non-operated state is provided with a D.C. bias of a value intermediate those required for operation and release. Relay R is biased in this manner from a D.C. source connected between terminal B and earth, the biasing network comprising resistors 1, 9, 2. In the normal position a capacitor 7 is charged to the potential of the source B via relay contacts r 21 , r 22  and contacts 5 of push-button 3. Further relay contacts r 11 , r 12  short the terminal M, to which switching-off impulses are applied, to the terminal B. If push-button 3, which is spring-loaded, is pressed and released, closure of contacts 6 causes capacitor 7 to discharge through the relay R, thereby changing it to its operated condition. Contacts r 21 , r 22  thereby open and r 22 , r 23  close (Fig. 2, not shown), so that the capacitor 7 is fully discharged over resistor 11. At the same time contacts r 11 , r 12  open. The circuit remains in this condition until a switching-off pulse is applied to terminal M, whereupon relay R drops out and the circuit reverts to its original state. Resistor 9 and capacitor 10 are provided to reduce the potential at the point 8 for the switching-off pulse below the potential applied to terminal B and so reduce the switching-off pulse necessary. The switching-off pulse may be produced by a monostable circuit, and in the case of a television receiver, this may be actuated in response to reception of the sound interearrier frequency.

Abstract: 842,530. Heat exchangers. ROSENBLADS PATENTER A.B. ,Dec. 22, 1958 [Jan. 4, 1958], No. 41243/58. Class- 64(3) In a heat exchanger comprising a bundle of tubular elements 1 (Fig. 1) connected to a tube plate 2 itself connected through an elastic partition wall member 5 to a casing 7 enclosing the tubular elements, and wherein one fluid flows through the elements 1 and another fluid flows through the casing 7 over the elements, a rigid wall section 4 extends around the edge of the tube plate and is connected to the elastic member 5 by its attachment edge remote from the tube plate, the member 4 being so designed that in the event of a pressure difference between the heat exchanging fluids, the rigid wall section 4 will be exposed to a force dependent on said pressure difference and acting in the opposite direction, and being at least approximately as great as the force exercised by the elastic member at the attachment d (Fig 2). Hence no force due to pressure differences in the fluid passages is trans. mitted to the tube plate 2. Fig. 2 illus. trates in diagrammatic form the embodiment shown in Fig. 1 and in order to effect the desired counterbalance of forces should a fluid pressure difference arise, the surface c-d on the rigid member 4 is so proportioned that its area equals half that of the area a-b on the elastic member 5, a being regarded as fixed so that the reaction at b equals half the total pressure on the surface a-b and hence is balanced by the effective fluid pressure difference acting on surface c-d. The elastic partition member 5 may be in the form of a bellows or a diaphragm, which may be corrugated concentrically.
