Title: Improvements in or relating to means for indicating or recording pressure
IPC: G01L23/12
Filed: 1947-05-29
Abstract: 633,148. Electrically-operated pressure indicators. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. May 29, 1947, No. 14310. Convention date, May 16, 1944. [Class 40 (i)] The elements determining the separation of the diaphragm and counter electrode in a capacitor type pressure - sensitive device used, e.g. in taking indicator diagrams of combustion engines, are so dimensioned that the relative variation of capacity with pressure is independent of the temperature variation of the modulus of elasticity of the diaphragm material. The device, as shown, comprises a holder 1 threaded at 2 for screwing into the cylinder wall, e.g. of an I.C. engine, and containing with a small amount of play, a cup 4, the bottom 5 of which constitutes the diaphragm electrode. The cup 4 is welded to a bush 6 screwed into an extension 7 of the holder 1, and contains a central porcelain plug 8 whose bottom end carries the counter-electrode 9. The plug 8 has a shoulder pressed by a spring 10 on to the re-entrant edge of a metal bush 11 nested within the diaphragm cup, the bush forming together with a metal coating 12 on the porcelain plug a compensating condenser having a negative temperaturecapacity co-efficient. The temperature variation of the device is due to two factors, (a) the linear expansion of the elements 4, 8, 11 determining the separation of the electrodes 5, 9, and (b) the temperature-variation of the modulus of elasticity of the diaphragm material. The Specification shows in detail how by judicious choice of the dimensions e<SP>1</SP>, e<SP>2</SP> determining the separation of the electrodes 5, 9 the relative capacity variations due to pressure on the diaphragm may be rendered independent of the second factor (b). The first factor (a) is compensated by the compensating condenser 11, 12 which follows closely the temperature changes of the diaphragm condenser 5, 9. Both condensers are connected in adjacent arms of an A.C. measuring bridge, Fig. 2 (not shown), and the capacity ratio of the two condensers is so chosen that the bridge output depends only on pressure variations, which are indicated, e.g., on a cathode-ray tube actuated by the bridge output through an amplifier and detector.

Title: Improvements in or relating to record-controlled photographic apparatus
Filed: 1939-05-13
Abstract: 529,177. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd. May 13, 1939, No. 14360. Convention date, May 14, 1938. [Class 106 (i)] [Also in Groups XL and XX] Photographic apparatus associated with statistical apparatus comprises in combination means for feeding a series of statistical records, means for reading the records in succession for setting up a representation of each record in succession, and means for photographing each record representation in succession. As shown,. the records are frames on a film 20, Fig. 1, formed with feed perforations 21. Each frame contains data in actual digits 23 repeated in code form by spots 22. The film 20 is fed from a. spool 25, Fig. 4, to a spool 26 through a photoelectric apparatus which scans the code spots 22 of the film. A lamp 32 on one side sends light through the film to a set of quartz rods on the other side leading to a set of photo-electric cells, 34. The cells are connected to amplifier with relays controlling electromagnets 73, Fig. 7, which determine the stopping positions of rods 55, 56 lifted through linkwork by springs 68 when allowed to do so by cams 59. The rods 55 carry digits and the rods 56 carry spots, and under the photo-electric control the digits and the spots are set to correspond to the digits and spots of the frame on the film 20. An image of the representation of the digits is formed at 89 on a film 90 by an objective 87, and an image of the representation of both digits and spots is formed at 93 on a film 94 by an objective 91. These images are photographed and the films 90, 94 moved one step to receive the next impression. The whole apparatus is driven by a single motor and all the operations are automatic. Each frame of the primary record film 20 is scanned in turn by the photo-electric apparatus, this sets up the equivalent representation of digits and spots of the rods 55, 56, the shutters of the objectives 87, 91 are tripped to make the exposures of the films 90, 94, these films are then fed one step, and the operations repeated for the next frame on the primary film 20. A spring contact co-operates with a feeler in conjunction with each film to break a circuit to stop operation if the film is not present. The record used in this apparatus may be produced as described in Specification 429,950.

Filed: 1974-04-01
Abstract: 1462428 Automatic control TOKYO SHIBAURA DENKI KK 1 April 1974 [2 April 1973] 14393/74 Heading G3N The traverse of a crane is controlled in dependence on calculations whereby the areas under the acceleration and deceleration phases of a speedtime pattern are made equal so that swing of a rope, suspending a load, can be minimized. As shown, a crane installed on a wharf for transport of containers between a ship and a yard is controlled by an operator applying an off-board commencement signal to a unit B which form a maximum running speed signal Vmax corresponding to the deviation # L  (Lo) of the present position of'a trolley from a target position. This signal is applied to a pattern generator C, together with a signal l representing length of hoist rope. A pattern signal is then generated whereby the swing # of the container is reduced to zero at speed Vmax. At this point, a signal generator A compares the distance S required to stop the trolley with the present position # L  and applies a speed command signal O when # L  equals S. The generator C then causes the trolley to decelerate and stop at the target position at which the swing should again have fallen to zero. The controller D comprises a comparator to which a feedback signal is applied from a tachogenerator TG coupled to the motor M.

Title: Display drive circuits
IPC: H04N3/12
Filed: 1975-04-08
Abstract: 1529342 Displays; matrix displays and circuits therefor POST OFFICE 2 April 1976 [8 April 1975] 14424/75 Headings G4H and G5C One or more selected intersections of row and column conductors of a display screen are activated by applying a first potential to the corresponding row(s) (say) and ground to the corresponding column(s), the other rows receiving a second potential and the other columns receiving a third potential, the second and third potentials lying between the first potential and ground. As disclosed, the second and third potentials are equal and each lies half-way between the first potential and ground. The potentials are D.C. and the display is of the phosphor-dot electroluminescent type, the control circuitry being integrated. In a first embodiment, the intersections are scanned sequentially, scanning of the columns being under control of demultiplexers and scanning of the rows being under control of read-only memories. The lst-3rd potentials (70V, 140V) are obtained from 5V by a step-up transformer preceded by a two-stage buffer amplifier receiving the 5V and a clock signal to pulse the supply on and off, the transformer secondary being centre-tapped and including diodes and being followed by selectable Zener diodes. In a second embodiment, the display matrix displays four rows of characters, each character in 7 x 5 dot matrix form. As the columns of the display matrix are selected in turn, the appropriate rows are selected by 4 row driver units controlled from respective character generators, the 4 character generators being controlled by respective address registers via respective latch units. The address registers are shift registers performing serial-to-parallel conversion and fed from a data input line via a demultiplexer. Each row driver unit drives 7 rows. Four power supply units are provided, each associated with alternate rows in each of two row driver units, and used in conjunction with the character generator outputs to control complementary pairs of transistors to gate the appropriate potentials to the rows. The columns can be divided into two groups, driven from respective opposite edges of the display screen using respective column drivers, or division into four or more groups may be used. Brightness is controlled in both embodiments by controlling mark/space ratio of pulses.

Filed: 1961-04-21
Abstract: 953,664. Supply systems for discharge lamps. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 21, 1961 [April 26, 1960], No. 14544/61. Heading H2H. The secondary winding 6-7 of a transformer in a supply system for a gas or vapour discharge tube 10 connected to its extremities, comprises two series connected parts 12, 7 and 6, 11 respectively loosely and tightly magnetically coupled to a mains connected primary winding 2, 3, the no-load secondary voltage being such as to ignite the tube 10 in its cold state, and so cause a voltage derived from tappings 13, 14 on the two secondary parts to drop below that at which a slow to make voltage relay 17 connecting them will operate so as to close its contacts. The voltage relay 17 may be of the glow discharge type and be shunted by a capacitor. If the tube 10 is inadvertently extinguished, the noload secondary voltage may be insufficient to re-ignite the hot tube, but the no-load increase in voltage at the tappings 13, 14 closes the contacts 15, 16 after about a 1-second delay, and thus shorts the windings 13, 11 and 12, 14. The surge voltage produced when the relay 17 re-opens after about half a second, or after several such re-openings, will be sufficient to re-ignite the tube 10. If the tube 10 ignites directly at the no-load transformer output voltage, the operating delay of the relay 17 prevents the contacts from closing. For optimum results the tappings 13, 14 are arranged so that the windings 13, 11 develops some 70% of that available from windings 12, 14.

Abstract: 292,582. Soc. Anon. la Cellophane. June 24, 1927, [Convention date]. Sausages.-A casing or container for moist products such as sausages, jam, honey, pharmaceutical products such as salves and ointments is made from a sheet of regenerated cellulose which is formed into a tube by autogenous welding along two overlapping edges. The autogenous welding is effected by treating the said edges with a solvent, e.g. concentrated chloride of zinc, and then pressing the edges together, e.g. by winding the flattened tube on a mandrel. After welding, the solution is removed, e.g. by washing with water. The casing may be made continuously by passing a strip of cellulose, from a bobbin, between guide members which fold it over. Previous to the two edges meeting, one of them is treated with the solvent.
