Title: Circuit interrupter
IPC: H01H33/12
Filed: 1961-12-11
Abstract: 966,110. High-voltage switches. S. & C. ELECTRIC CO. Dec.11, 1961 [May 23, 1961], No. 44181/61. Heading H2B. A circuit interrupter comprises a cylindrical insulating casing 33 containing gas at superatmospheric pressure, hermetic seals at the ends of the casing, terminal assemblies 34, 35 including annular flanges 57 cemented at the ends of the casing, separable contacts in the housing interconnecting the terminal assemblies and operating means 90 for the contacts extending out of the housing through one of the seals. In the arrangement shown, the contacts comprise a main moving contact 86 which bridges fixed slotted tubular contacts 80 and a movable auxiliary contact 144 which co-operates with a resiliently mounted fixed contact 140. The contacts are operated by respective operating rods 90 extending through bellows 98 providing seals between the rods 90 and contact-carrying tubes 75, 149 brazed to a plate 53. This plate has a flange 55 which is soldered at 56 to an annular diaphragm 47 which is soldered at 50 to a metallic band, e.g. of platinum, on the end of the casing. The seal at the left-hand end of the casing is provided by a diaphragm 40 similarly soldered to the casing and provided with a tubular extension 44 having a closure plate 179. A filling tube 182 secured to a bellows 177 extends through an aperture in the plate 179 and carries a latch 188. When the pressure in the casing falls, a spring 184 moves the bellows, tube and latch sufficiently to release a spring-loaded indicator drum 193 from the latch. The movable auxiliary contact 144 is tubular and is carried within a nozzle assembly 145 so that when this assembly is drawn into the tube 149 on opening of the contacts a gas-blast is formed through and around the moving contact 144. The gas may be at pressure of the order of two atmospheres and consist of sulphur hexafluoride or other gas. Decomposition products of the gas due to arcing may be removed by cylinders 167 of activated alumina with or without sodium hydroxide, or of calcium carbonate. The contact assemblies are additionally supported by plates 112 interconnected by insulating rods (not shown), which in an arrangement having multiple series-connected main and auxiliary contacts, are provided with high resistance coatings for voltage distributing purposes. The Specification describes the interrupter as forming part of a load-break disconnecting switch which also includes an air-break isolator and a common operating mechanism as described in Specifications 898,462 and 898,463.

Title: Control mechanism for a reflex camera
IPC: G03B17/42
Filed: 1973-09-21
Abstract: 1446647 Reflex camera mechanisms ASAHI KOGAKU KOGYO KK 21 Sept 1973 [22 Sept 1972] 44391/73 Heading G2A In a reflex camera the action of opening the shutter locks the film wind mechanism, which is released again after the shutter is closed. This ensures that no film transport can take place while the shutter is open. Fig. 1 shows the mechanism in the mirror-down or viewing position, the mirror 2 being biased into this position by a spring 4. When the shutter release button is operated, a control lever 12 is pivoted anti-clockwise, which releases a spring-loaded drive lever 10 to rotate anticlockwise. A roller 10a or lever 10 engages and pivots a lever 5 clockwise which engages and pivots the mirror to its up position Fig. 3 (not shown), a pin 7 on lever 5 also pivoting anti-clockwise a lever 8 to engage a member 16 which opens the shutter. Also rotation of lever 10 engages and pivots a lever 17 anti-clockwise against a spring 26 Fig. 4 until a pin 18 thereon latches into a notch at the end of a lever 27, and is then held in that position. After lever 12 is initially pivoted anti-clockwise, it is retained against return by a member 15 on an arm of lever 10. In so pivoting, lever 12 engages and pivots a lever 20 clockwise, which in turn pivots a lever 22 anti-clockwise Fig. 4. An end 22a of lever 22 thereby engages in a notch 24a in a cam 24 and locks it against movement. Cam 24 is part of the film wind-on mechanism, so that the wind-on is inhibited for as long as the shutter is open. On closure of the shutter, pin 18 is released, allowing lever 17 to rotate clockwise, which accordingly engages and pivots lever 10 clockwise, so returning the mirror 2, diaphragm lever 11, member 16, and other associated components to the original Fig. 1 position. Lever 12 is rotated clockwise by its spring 25, so allowing lever 22 to rotate clockwise under spring 23. This brings end 22a out of engagement with cam 24, so permitting film wind again.

Title: Production of colour photographic records
Inventor: MACDONALD ERIC
IPC: G03C5/40
Filed: 1959-12-31
Abstract: 908,299. Photographic colour processes. ILFORD Ltd. Feb. 27, 1961 [Dec. 31, 1959], No. 44457/59. Class 98 (2). Photographic colour records are produced by subjecting a photographic material carrying a silver image to an aqueous solution containing cyanide ions in the presence of a tetrasodium salt of a formazan dye. Specified formazan dyes are wherein R 1  and R 3  are aryl or hetorocyclic radicals, A is an alkylene or arylene group and R 2  is a hydrogen atom, alkyl or substituted alkyl, aralkyl, aryl, hydroxy, mercapto, cyano, amino, acyl, carboxy or heterocyclic radical. The tetrasodium salt is reduced to the formazan dye by the cyanide ions only in areas carrying a silver image. Multilayer photographic material containing different tetrasodium salts in each layer may be developed to give different coloured images in each layer. In Example I paper carrying a negative silver image is placed in a bath containing potassium cyanide and 2 : 3 : 5 triphenyltetrazolium chloride producing a magenta image, bleached and fixed. In Example 5, a solution of 2: 3 diphenyl-5-4<SP>1</SP> dodecencyphenyltetrazolium acetate is added to a silver halide emulsion, coated on paper which is exposed, developed, fixed and placed in a cyanide bath producing a magenta image.

Title: Electronic temperature monitoring system
IPC: G01K7/02
Filed: 1970-09-23
Abstract: 1322790 Measuring temperature electrically GOODYEAR TIRE & RUBBER CO 23 Sept 1970 [21 Oct 1969] 45357/70 Heading G1N [Also in Division H3] The temperatures at a number of locations are sensed by thermocouples 12-18 Fig.1, each of which is connected via an amplifier 20-26, and a comparator 28-34, whose output is "high" or "low" depending on the relative values of the temperature signal voltage and a reference voltage, to a series of gates 50-56, 58, 60-66. When a temperature signal exceeds the reference voltage the gates in the corresponding channel change their conditions. The change in one of gates 50- 56 switches a gate 70 to light a first lamp 36, and the change in one of gates 60-66 switches a gate 68 to light a second lamp 38. A switch bank 48 enables the overheated location to be identified by selectively feeding the equivalent of a low temperature signal to all but one gate 60-66 and noting which gate is thereby changed over, The switch bank 48 also enables the individual thermocouple output signals to be indicated on a meter 42, the meter readings also identifying various types of faults. Each comparator 28-34 comprises an amplifier I.C. Fig.3 whose input is the measured signal Eb and a reference voltage Ea. When the former exceeds the latter the amplifier output voltage Eo is switched from a high to a low value, causing a change in the reference voltage Ea, by virtue of the current through resistors R15, R16, which introduces a hysteresis effect to prevent hunting at the critical temperature. An excessively high input signal is fed via Zener diode Z Di  to maintain the output signal from transistor Q2 at the normal low value. Variations in the temperature signal due to change in the cold junction temperature of the thermocouple are compensated by the voltage across a platinum resistance wire fed with a constant current and maintained at the same temperature.

Title: Lifting truck having a control member adjustable into three  different positions
IPC: B62B5/06
Filed: 1973-09-27
Abstract: 1387789 Pallet trucks BYGG-OCH TRANSPORTEKONOMI (BT) AB 27 Sept 1973 [3 Oct 1972] 45368/73 Heading B8H A pallet truck is provided with a steering tiller 1 which is also used as a pump lever for a jack operated lift device for raising and lowering the load carrying member of the truck, a control lever 2 being mounted for movement about a shaft 6 on the tiller 1 and being connected to the jack operated lift device by means of a rod 4, the lever 2 being locatable in three positions, as shown. In the upper position the jack operated device is operated to lower the load carrying member while in the middle position the tiller 1 is connected to the jack operated lift device so that elevation of the load carrying member is achieved on rocking the tiller, and in the lower position the tiller 1 is disconnected from the jack operated lift device such that the tiller 1 can be moved to its phantom line position of Fig. 1 (not shown), in which it is used for steering the truck. The rod 4 is spring loaded in a downward direction so that the lever 2 tends to move into the said lower position. In its middle position the lever 2 can be temporarily locked to the tiller 1 by means of a spring (7) in the lever 2, Fig. 3 (not shown), the ends of the said spring engaging respective balls 3 which engage in recesses in the tiller 1. Through adjusting the force of the spring (7) it is achieved that when the lever 2 is released from its upper position it is automatically pulled down to its lower position without stopping in its middle position. In order to bring the lever 2 to stop in its middle position the operator must hold it there until the spring (7) engages the balls 3 in their respective recesses.

Title: Improvements in or relating to remote control installations
IPC: H02J13/00
Filed: 1963-11-18
Abstract: 976,462. Electric selective signalling systems. SIEMENS-SCHUCKERTWERKE A. G. Nov. 18, 1963 [Nov. 16, 1962], No. 45492/63. Heading G4H. A field station system is characterized in that the central station and each field station includes a cathode ray tube which distributes received data and produces clock pulses for transmitting data. As described all the cathode ray tubes are synchronized by a source pf clock pulses 14 and each complete scan is divided into an upper-half, or transmit cycle, during which the central station G can transmit data to the field stations, and a lowerhalf, or receive cycle, during which the central station can receive data from the field stations. During a transmit cycle the central station cathode ray tube applies pulses sequentially to a number of leads, one for each of a number of switches 11, each one of which has a corresponding switch in one of the field stations. As the switches are scanned each one that is closed causes a pulse to be applied to the transmission line which pulse brightens the cathode ray tube beams in all the field stations. At the field station which contains the switch corresponding to the central station switch which caused the beam to brighten a connection will exist so that in response to the brightened beam a device 30 is tripped to actuate the switch to the desired position. During a receive cycle switches at the field stations are scanned by pulses from their cathode ray tubes, any closed switch causing a pulse to be transmitted to brighten the central station cathode ray tube beam which, via a device 10, controls indicators so that the central station supervisor knows the positions of the switches in the field stations. The pulses from the cathode ray tubes can be produced either by an array of photo-electric cells adjacent to the face of the tube or by target electrodes in the tube.

Title: Improvements in or relating to data analysing systems
IPC: G01T1/204
Filed: 1968-09-25
Abstract: 1,218,845. Measuring radio-activity. PACKARD INSTRUMENT CO. Inc. Sept.25, 1968 [Sept. 28, 1967], No.45538/68. Heading G1A. In liquid scintillation apparatus the relationship between the energy spectra and the channel limits is so adjusted in accordance with the measured quenching of the sample to maintain optimum counting conditions. In multiple labelled samples this means maximizing isotope separations, and with single labelled samples it means maximizing E<SP>2</SP>/B where E is the isotope counting efficiency and B is the background count. The quenching may be measured as in Specification 1, 218, 844 and used as described therein to provide simulated quench to bring the effective quench level to one of the few predetermined values at which the counting efficiency is accurately known. In order to optimize counting conditions by adjusting the channel limits, the binary coded second most significant decimal digit in the measured quench is applied to a code converter for each limit, such as 99, Fig. 17 to mark a binary O on a corresponding line b.0 to b.9 and cut off a corresponding transistor Q0-Q9. This enables the circuit through the corresponding R 0 -R 9  and D 0 -D 9  and the load resistor R L , the voltage across which controls the corresponding discriminator level. If it is desired to measure counts per minute without automatic channel control, switch DPM is turned off and the channel level is controlled by resistor Rcpm. In a modification, Figs. 18 and 19 (not shown) the relationship between the spectra and the channel limits is controlled by varying the gain in each channel. In this case resistors corresponding to R 0 -R 9  which are selected by transistors Q 0 - Q 1  switched on by the marking from code converter 99, form a voltage divider with a common resistor. Optimization of the counting conditions may be effected by adjustment of both gain and channel limits.

Abstract: 1492554 Continuous casting G PROPERZI 22 Dot 1974 [22 Oct 1973 4 July 1974] 45666/74 Heading B3F The rim ring 3 of a wheel-and-belt casting machine is supported by two members, e.g. hollow discs 5, coaxially with a drive shaft 11 and has edges which rest on ledges on the members for freedom of axial movement, e.g. between shoulders on the discs as shown, but is constrained to rotate with the shaft and discs as by keys (5b) interlocking the edges and ledges; cooling apparatus 6 is mounted between the members to remain stationary during the wheel's rotation. As shown the edges are inturned, but they may be wholly parallel to the axis of rotation. The discs 5 are mounted on an extension 10 keyed to or integral with the end of the drive shaft 11 which is journalled in a stationary housing 15 of a drive pulley 14. The inner (right hand) disc 5 may be fast with a sleeve shaft (Fig. 1, not shown) rotatable on a hollow rod on which the outer disc is rotatable. The hub 21 of the stationary cooling-spray apparatus 6 constitutes a header fed through a bore 19 in the drive shaft 11 or through an axial hole in the outer disc 5 and radial openings 16. Radial ducts 7 pass the coolant to an outer, ring header 8 to feed spray nozzles 9. Coolant, accumulating at the bottom of the wheel, drains through holes 28 through the discs 5. The cooling apparatus 6 remains stationary because a shaft 26 rotatably mounted in one disc bears gear wheels 24, 25 at its ends and they revolve as planet gears about ring gears 22, 23. Alternatively, if the wheel is spoked, resilient detents may be positioned between the spokes, to be withdrawn in succession, under the action of the moving spokes, to move back as a spoke passes by.

Abstract: 1444821 Equalizer for partial response signals SIEMENS AG 1 Oct 1973 [5 Jan 1973] 45711/73 Heading H4R In an equalizer for a transmission system employing partial response signalling tap gains of a transversal filter are adjusted by correlation of an error signal derived from the equalizer output with a signal from an adder combining signals from more than one tap of the equalizer delay device. As described the signal is of the form where a "1" is transmitted as the sequence "+1, 0, - 1," and the signal received from the transmission system is applied to the shift register having stages 26, 27, 28, connected by variable gain amplifiers 45, 46, 47, 48 to an adder 23 from which the output of the equalizer is derived. The equalizer output feeds both directly, and via a theoretical value detector and inverter 37 to the respective inputs of the adder 24 so as to derive an error signal which is fed to the correlators 35, and 36. Also fed to the correlators are signals from adders 21 and 22 each of which derives its inputs from points on the shift register spaced by two stages, and the output of the correlators is used to modify the gain settings of the respective amplifiers 47, 48. The shift register 26, 27, 28 and amplifiers 45, 46, 47, 48, remove the pre-pulse distortion while post pulse distortion is removed by the shift register 30, 31, 32, 33, and variable gain amplifiers 49, 50, which portion of the equalizer is the subject of the Specification 1,444,322.

Filed: 1969-09-17
Abstract: 1278097 Typewriters ING C OLIVETTI & C SpA 17 Sept 1969 [9 Oct 1968] 45902/69 Heading B6F In a typewriter in which characters are required to be linked together and which has a carriage movable transversely step by step, a space key 52 effects a partial step and while being held depressed a character key 8 is then depressed. The release of both keys completes the spacing so that when the next character 93 is typed it will be linked to the one before 92. In a similar way if it is required to link a subsequent character 97 to the one before it, i.e. 96 which has already been typed, then depression of a special back-space key 88 and the subsequent character key 8 will effect linkage during typing of the right-hand part of the composite character. The mechanism comprises an escapement mechanism having a rocker 23 operated by a type-lever engaging bail 16 via projection 37 and arm 28 of the rocker 23, a space bar 52 via linkage 50, 49, 48, 47, 46 and a stud 35, and also from the special back-space key 88, via. linkage 87, 86, 85, bail 83, 76 79 and a second arm 32 of the rocker. Movement of the rocker 23 disconnects the movable pawl 26 from the ratchet wheel and a retaining pawl 38 into the wheel. The retaining pawl 38 however is not completely fixed as normally but allows a partial letter-space to occur since it is pivoted at 41 and the carriage pull via the rack 22 and ratchet 18 moves the pawl 38 against a shoulder 42 on the rocker. If this movement was effected by the space bar 52 so that a left hand character is moved to the right the type-lever is now depressed. This does not effect actuation of the rocker because the space bar has already done so, but upon release of both keys the normal full letter-spacing is completed. A similar action occurs when moving a righthand character to the left but in this case the back-spacing key is used.
