Title: Remote-control operating systems for electric circuit-breakers
IPC: H02J13/00
Filed: 1949-06-03
Abstract: 663,001. High-tension switches. FORGES & ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. June 3, 1949. [June 4, 1948; Oct. 19, 1948] Nos. 14981/49 and 14982/49. Class 38 (v). A circuit-breaker having its operating mechanism and compressed-air tank mounted on insulators 6, is remotely controlled by radio, the receiver 7 being connected electrically to the operating mechanism by a flexible connection 13, 14 and protected from vibration due to operation of the circuit-breaker by being mounted on a separate, insulator 10 which is rotatable about its longitudinal axis for manual operation of the circuit-breaker and is also able to pivot in the vertical plane for isolating the receiver from the high-tension. The receiver may control closing or tripping relays, the former acting through electro-valves, or releasing springs which open operating-air valves which are reclosed by the breaker parts or by servo-motors controlled thereby. The tripping relay may release a latch or act through other relays or a servo-motor. Alternatively, when automatic reclosing is desired, the receiver may control a single relay, which causes pneumatic closing, and pneumatic or spring opening, of the breaker. The latter may also open when air pressure is low or when the receiver does not function properly, and the poles can be opened separately or together. The safety measures necessary when the receiver is to be examined preferably involve rotation of the insulator 10 about its own axis so that an arm 15 carried thereby operates a fork 16 to open the breaker, the insulator then being moved about the pivot 12 to the dotted position, any capacitative currents being broken at an auxiliary connection between the breaker and the receiver. If other safety measures are used, the means such as cams, keys, &c. blocking immediate movement of insulator 10 about pivot 12 are automatically withdrawn and the breaker remains closed.

Title: Improvements in or relating to signal discriminator circuit arrangements
IPC: H04B3/10
Filed: 1959-05-04
Abstract: 864,713. Voice immunity systems. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING A.G. May 4, 1959 [May 14, 1958], No. 15164/59. Class 40 (4). A pure signalling frequency operates a relay by producing a D.C. from a first rectifier, a second rectifier receiving the output of the first rectifier so that in the event of noise accompanying the signalling frequency, cross-modulation in the first rectifier produces an A.C. output which is rectified in the second rectifier and applied in opposition to prevent operation of the relay. As seen in Fig. 1, the signal is applied over filter 1 and amplifier 2 and is rectified at 4 with a smoothing capacitor 5 across which, at the signal frequency, no significant A.C. is supported. Cross-modulation of noise produces a low-frequency A.C. signal across capacitor 5 which over capacitor 6 is rectified at 8 and applied to relay 7 in opposition to the signal from rectifier 4. As seen in Fig. 2 a triode 9 is worked in Class C, capacitor 6 taking crossmodulated components to a rectifier 8 which produces back-bias on the triode.

Abstract: 292,160. Joachimson, M. June 16, 1927, [Convention date]. Coating bakers' goods.- Apparatus for coating slices of bread or the like with butter, jam or similar substances, comprises a butter container 76, a continuously rotated roller 77 journaled therein, and a support , e.g.. a conveyer 20, which carries the slices into contact with the roller. The conveyer 20 and its driving means are described in Specification 292,161. The container 76 is continuously supplied with butter from a hopper 70 having a pivoted flap valve 702, the opening of which is controlled by an adjustable screw 705. The butter is kept at the correct temperature by an electric heater in the hopper 70 controlled by a. thermostat element in the container 76. The thermostat 402, heater 401. and hand-switch 403 are shown in Fig. 9. The thermostat consists of a flat blade or reed of two metals which close a circuit by their bending due to heat. The thermostat and heater are each enclosed in a tube. The container 76 is pivoted on trunnions 82, 820 and balanced by weights 84, an adjustable screw 85 limiting its angular movement. The container 76 has a bottom which slopes towards the roller 77 which closes the front end of the container. The roller is of greater width than the belt 20, its ends being received in widened portions 78 of the container walls. The roller is rotated, by gearing, the peripheral speed being the same as the linear speed of the bread slices. A knife 80 is carried on the container bottom adjacent to the roller 77, to control the thickness of butter to be applied by the roller to the slices. The knife 80 is adjusted by an eccentrically mounted shaft 762 rotated by a dial-faced knob 7<j3, a spring 764 engaging grooves in the periphery of the knob 763 to indicate the butter thickness. The journals and driving-means for the roller 77 are shown in Figs. 4, 7. The roller is supported on centres 771, 774 which may be withdrawn against springs 772 by knobs 773, when the roller 77 is to be removed. The roller is driven by a belt 303, pulleys 210, 301, clutch 307 and gear wheels 308, 310. The pulley 301, wheel 308 and clutch are co-axial with the trunnions 82, 820, the wheel 308 being driven by a pin on the withdrawable clutch block 304 engaging a hole in the side of the wheel. The roller 77 is similarly driven by a pin 775 on the centre 771 engaging a hole in the end wall of the roller 77. Gutters 781 collect drippings from the container 76 and lead to transverse gutters which discharge into collecting vessels at the side of the machine. A scraper 791 prevents crumbs from passing into the container.

Abstract: 1288316 Keratometer B NUCHMAN and S Y WHANG 2 April 1970 [7 April 1969] 15680/70 Heading G2J A keratometer of the type having a first set of illuminated wires 69, 70 for producing inside a human cornea 66 a virtual image 76 whose size is a measure of the curvature of the cornea in a first region 78, has a second set of illuminated wires 44-47 spaced along the optical axis 85 of the keratometer from the first set of wires for producing a second virtual image 82 whose size is a measure of the curvature of the cornea in a second region 84, and a diverging lens 38 for producing from the image 82 a secondary virtual image 88, the lens and the spacing between the two sets of wires being such that the keratometer reads directly the radius of curvature at the second region 84 by measuring the size of the image 88. The curvature of the cornea in the region 78 is first read off the conventional keratometer, to which is then attached an accessory 10 Fig. 4 comprising a housing formed from two threadedly connected members 12 and 14 defining an annular chamber 48 in which is a plurality of lamps 50 which illuminate the wires 44-47 in plate 32, which has a central aperture 36 wherein the lens 38 is mounted. The keratometer is moved away from the eye so that wires 69, 70 are now at 69<SP>1</SP>, 70<SP>1</SP> and are obstructed so that they project no image, while the second set of wires produces image 82. The dimensions of the instrument may be such that the size of secondary virtual image 88 is equal to the size of image 76 were the radius of curvature at 78 equal to that at 84, and so that the distance d 2  equals the distance d 1  (see Fig. 4). The lens 38 need not necessarily be in the plane of the wires 44-47, and it could be replaced by a more complex divergent lens system. The lamps 50 may be replaced by fibre optics or other illuminating means.
