Title: Device for generating acoustic waves by implosion
IPC: G01V1/133
Filed: 1971-09-22
Abstract: 1322823 Seismic energy generators INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 22 Sept 1971 [24 Sept 1970] 44231/71 Heading H4D A source for generating acoustic waves by implosion in a liquid medium (e.g. for marine seismic prospecting) comprises an immersed chamber defined by a wall 1 and by end 2, a sealing member 7 which can be intermittently pressed against wall 1 to close the chamber, and means for establishing in the chamber when closed by member 7 a pressure below the ambient hydrostatic pressure. The sealing member 7 shown is a flexible membrane secured to tube 3 to define an enclosure. With the enclosure collapsed as in Fig. 2, a valve V1 is set to supply compressed air from tank 10 to the chamber via tube 8 to force the liquid medium (water) out of the chamber. Valve V2 is then set to supply compressed air to the enclosure via tube 3 and apertures 4 to press sealing member 7 against wall 1 (as in Fig. 1). Electrically operated valve EV is now closed and both tubes 3 and 8 are connected to vacuum reservoir 11 via valves V1, V2. The source is fired by opening valve EV, whereupon the enclosure collapses and water rushes into the evacuated chamber to generate acoustic waves.

Title: Improved method and apparatus for handling freshly-printed sheets
IPC: B41F23/04
Filed: 1966-10-05
Abstract: 1,147,363. Finishing printed paper; sheet delivery. MILLER PRINTING MACHINERY CO. 5 Oct., 1966 [8 Oct., 1965(2)], No. 44443/66. Headings B6C and B6H. A method of conditioning sheets freshly printed with ink comprises first applying heat and then cooling and humidifying the sheets during their continuous transfer from a printing unit to a delivery unit. Figs. 1a, 1b and 1c taken together constitute a side elevational view of apparatus according to the invention; sheets -printed between the impression cylinder 3 and the blanket cylinder 5 of an offset press are taken by transfer cylinder 6 and are then gripped by the gripper bars of a sprocket chain 11 which is trained about sprockets 12 and 13 and guided by guides 14, 15 and 16. The sheets are carried by the composite endless element 11a, comprising the chain 11 and the grippers, between an infra-red dryer 17 and reflector 18 to promote setting of the ink and volatilize any volatile constituents of the ink: the paper then passes upwards through a gas dryer 19 in which flames 19a, directed against the faces of the paper, set the ink and burn the remaining volatile constituents, any residue being removed by air knives 20. The endless element 11a then carries the paper around chill roller 8; the element is cooled by spraying with water in a chamber 21a, and then dried by air jets 21c. The paper is carried in turn about parts of further chill rollers 22, 23 equipped with grippers for the sheet and moistened by conventional damping apparatus including fountains 24. Individual sheets may be removed for inspection along shoot 59 (Fig. 8, not shown) Sheet delivery.-Suckers 63 connected to a vacuum line 65 in rotating arms 157 take sheets from the chill roller 23 and transfer them to one of a series of reciprocating suckers 66. Mounted in the supporting structure for continuous movement are a number of endless sprocket chains 89 carrying gripper assemblies 96a, the chain being guided by channels 94 and 95. Each gripper assembly 96a grips the leading edge of a sheet held by reciprocating suckers 66, the suction is then cut off. and the sheet is transferred and is swung into generally face-to-face relationship with the next sheet before being carried by chain 89 through a chamber 110 in which humidifying or, if necessary, dehumidifying is carried out. The grippers then release the sheets which fall in turn on to a pile support 111. Each gripper assembly 96a is illustrated in Fig. 3; rollers 101 and 105 are controlled by cam grooves 108 and 120 and thus orientate the grippers correctly for receiving sheets from suckers 66; outside the field of these grooves, the weight of the assembly causes them to assume positions B and C indicated in Fig. 1a. with the gripper 98 and the gripper pad 103 extending straight downwards and generally kept in contact with each other by coil spring 106 except when roller 101 rides up on cam 109 (Fig. 1b) which opens the jaws (i.e. parts 98 and 103) of the assembly and allows a sheet to come between them.

Abstract: 1,192,460. Semi-conductor devices. ALLMANNA SVENSKA ELEKTRISKA A.B. 2 Oct., 1967 [3 Oct., 1966], No. 44673/67. Heading H1K. In order to increase the heat-dissipation capability of a thyristor or other semi-conductor device such as a diode, and hence increase its current-handling capacity, semiconductor plates are cut from a circularly cylindrical crystal whose longitudinal axis coincides with one of crystallographic axis of the crystal at such an oblique angle to the axis of the crystal that the plane of the elliptical plate so produced lies in one of the (111) planes of the crystal. In the case of a silicon crystal whose axis coincides with a (111) direction, a suitable angle of cut occurs at approximately 70 degrees to the axis of the crystal and the ratio of major to minor axes of the elliptical plate is approximately 3. The diameter of the cylindrical crystal may be 30 mm.

Title: Improvements in and relating to apparatus for performing arithmetical operations in the system of residue classes
Inventor: HOFFMANN WALTER
IPC: G06F7/72
Filed: 1960-12-30
Abstract: 969,495. Calculating apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 30, 1960 [Dec.30, 1959j, No. 44816/60. Heading G4B. The Specification discloses hydraulic multiplying and dividing apparatus in which the operation is reduced to addition or subtraction by using representations of the operands which have properties in this respect similar to logarithms. A number N may be represented uniquely by listing its residues R i  mod.p i where p i  are coprime and provided that N<#p i . Thus 12329 may be represented by the number set (2, 4, 2, 9, 5) since 12329 = 2(mod3), = 4(mod5), = 2(mod7), = 9(mod11), and 5(mod13),and3. 5. 7. 11. 13 = 15015. Each p i  has a primitive root g defined by g p i -1/z = -1(mod p 1 ). Thus g = 2 for p = 11, since 2<SP>5</SP> = 32 = -1 (mod. 11). The power g<SP>n</SP> (n = 1, 2p i  - 1) of the primitive root of a prime p i  give the residue class of p i  and the number n for which g<SP>n</SP> = a particular residue R is called the index of that residue. The table gives the indices of the residues of some primes p i . The residue representation of a number may be replaced by an index representation. The index representation of 12329 is (1, 2, 2, 6, 9.) The property of these representations used in the present Specification is that if corresponding indices derived from a prime p i  in the index representation of the two numbers are added (subtracted) mod(p i  - 1) the result is the index associated with p i  in the index representation of the product (quotient) of the two numbers. For example: Summing the indices mod(p i - 1) but leaving the answer in mod p i  form gives (1, 3, 5, 10, 12) of which the equivalent residues are (2, 3, 5, 1, 1) which is the residue representation of 14873 = 139.107. Fig. 3 shows a hydraulically operated multiplier mod5. When one valve from each of the sets 41, 41<SP>1</SP>is opened the pistons 45 take up positions adjacent the tube 43, 43<SP>1</SP> having the open valve through which high pressure fluid from pipes 46 tends to flow. The linear motion of the pistons is transmitted to interfitting sliders 48, 50, which are so grooved that, dependent on the positions of the sliders, fluid from tube 58 flows through one of the output tubes 59. To the operator the tubes 40, 40<SP>1</SP> represent the operands and the tubes 59 the product but the tubes are so arranged at 42, 42<SP>1</SP> and 65 that the operands are represented to the machine as their associated indices, and the index output is converted to the residue product. Several such machines would be used to perform the multiplication of the respective residues of the operands. A hydraulic machine is also described (Figs. 3a to 3c not shown) for performing an operation 2x.4y/3z (mod5).

Abstract: 453,259. Gyroscopic apparatus. ASKANIA - WERKE AKT. - GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG.-FRIEDENAU, 87, Kaiser Allee, Friedenau, Berlin. Jan. 15, 1936, No. 1371. Convention date, Jan. 15, 1935. [Class 97 (iii)] To cause a directional gyroscope to precess back to its normal horizontal position when displaced therefrom, the rotor casing carries two nozzles from which air currents issue, the axes of the air currents being in the plane containing the axis of rotation of the rotor casing and perpendicular to the rotor axis, and the currents being of different strengths and so arranged that the reactive forces set up by them on the frame carrying the rotor casing oppose one another. As shown in Fig. 1, the nozzles 33, 34 are carried on the rotor casing 6 which is rotatable about bearings 7-8 carried on a frame 5 rotatable about vertical bearings 3-4. The nozzle 34 has an adjustable throttle 42, and the air currents caused to issue from the nozzles by pumping air from the casing through a pipe 12, impinge on triangular blades 45, 46 carried on the frame 5, Fig. 4, so that on tilting of the rotor casing about the bearings 7-8 the pressures on the frame due to the two currents oppose each other. The tilting introduces a torque about a vertical axis to process the rotor axis 10 back to its normal position. The Specification as open to inspoction under Sect. 91 describes a modification shown in Fig. 1 (Cancelled), in which the nozzles 23, 24 are carried on opposite sides of the rotor casing and are partly closed by blades 27, 28 fixed to the frame 5 so that when the rotor axis is horizontal the air currents from the nozzles are equally intercepted but on tilting the casing one current is intercepted more than the other thus introducing a torque to cause precession of the rotor back to its normal position. This subject-matter does not appear in the Specification as accepted.

Title: A cock for the automatic filling of bottles with liquids under gaseous pressure
IPC: B67C3/26
Filed: 1961-12-21
Abstract: 1,004,828. Bottling. CONSTRUCTION DE MATERIAL D'ALIMENTATION S.A. Dec. 21, 1961 [Dec. 29, 1960; Nov. 6, 1961], No. 45762/61. Heading B8T. The liquid and gas valves Y and H, J respectively of a counter pressure type filler are controlled pneumatically by a device Ve within the liquid reservoir R and supported by conduits C 1 , C 2  and C 3 . Diaphragms M 1 , M 2  on the device are operated by compressed air fed through conduit C1 and C2 respectively to move a stirrup Et vertically to control the passage of gas from the reservoir interior into the bottle. Fig. 1 shows the filler in the inoperative position, and when a compressed air valve VA1 is opened and a bottle urges a tulip Tp into engagement with the base of the reservoir to close a passage d, the diaphragm M1 expands upwardly and moves the stirrup vertically to allow compressed gas to flow from the reservoir through a tube T and the orifices K. If a bottle is not present the air leaks away at d and the diaphragm is not expanded. When the pressure in the bottle and reservoir are equalized, a spring Rt forces the tube T upwards until a shoulder L engages a fixed stop K; the valve Y is raised and liquid passes into the bottle through a grid g and past a member y urged downwardly somewhat against a spring. Valve VA1 is closed when liquid begins to flow and the gas valve is kept open by a spring 5, and gas in the bottle is returned to the reservoir via the tube T. When the liquid level reaches the orifices k its flow stops and member y moves upwards against the grid g to cut off the flow. A compressed-air valve VA2 is then opened and diaphragm M2 inflated thereby closing the gas valve HJ and liquid valve Y; in addition compressed air flows through conduit C3 whereby a diaphragm m is expanded to move a valve closure x inwardly against a spring r to allow the gas in the bottle neck to escape to atmosphere via the passages v, w, r and e. The lower portion of the tube T may be scoured of liquid by momentarily opening the valve VA1. A more elaborate construction is described in which, inter alia, the conduits C 1 -C 3  are circumferentially equally spaced, and the lower end of the stirrup slides about the upper end of the tube T. In a modification, Fig. 10, the pneumatic device consists of pistons 206, 207 in cylinders 204, 205 spaced by a base 203 through which compressed air supply passages pass. In addition to the three vertical conduits for supplying the cylinders for exhausting the gas in the filled bottle by operating a valve 237, a fourth conduit exhausts the cylinders from above the piston 206 and below the piston 207. The valve 237 is moved outwardly by compressed air against a spring 238 to remove a valve 236 from the end of a sealing 240, thereby allowing the escape of gas from a filled bottle. The main liquid valve comprises a solid portion 226 with a triangular head 231, and co-operates with a movable closure member 233 which is urged upwardly by a spring 235 and has a bearing surface engaging the liquid valve.

In a hydropneumatic suspension device for vehicles comprising a stepped cylinder 1, 18, 19 with a hollow plunger 2 which accommodates an elastic bag 4 filled with compressed gas and which is sealed against the upper part of the cylinder by means of a packing 3, the lower part 18, 19 of the cylinder accommodates a pumping device comprising a differential piston 5 carried by a spring 6 to pump liquid, which escapes from the pressure space A of the cylinder past the seal 3, back into the space A. The lower part of an outer jacket 7 comprises a liquid collecting space B which communicates, through openings 15, 16 and a suction valve 8, 20, with a pumping space C beneath the narrower portion of the piston 5 in the cylinder port 19. The wider part the piston 5 works in the cylinder part 18 and the piston has an axial bore 17 controlled by a spring-loaded valve 9. During a compression stroke the piston 5 descends to pump liquid from the space C past the valve 9 to the space A, replenishment of the pump space C taking place during a rebound stroke when the piston 5 rises and liquid is sucked into the space C past the valve 8. In the case where the pressure build-up in the compression space A is insufficient, during a compression stroke, to force the piston 5 downwards the latter is operated by a stop 14 carried by the plunger 2.

Abstract: 1,184,529. Starting fuel injection engines. SEA BIRD (CLEAN AIR FUEL SYSTEMS) Ltd. Oct.2, 1968, No.46685/68. Heading F1B. An adjustable stop for the control rack 6 of a diesel engine fuel pump is formed as a rotatable member 4<SP>1</SP> having three faces 7, 8, 9 which can sequentially abut an extension 2a of the rack 6 to set different limiting positions for the rack. For starting the engine, member 4<SP>1</SP> is rotated by handle 4 into an excess fuel position wherein face 7 abuts rack extension 2a to permit the pump to supply fuel oil in excess of the normal maximum. When the engine has warmed up, the extension 2a automatically retracts away from face 7 and a biasing device rotates member 4<SP>1</SP> clockwise so that face 9 is aligned with extension 2a. This position represents a maximum pump output of 70% normal maximum, the remaining 30% of fuel being supplied into the air induction pipe as liquefied petroleum gas (butane and/or propane). The biasing device comprises a spring-loaded plunger (10, Fig. 3, not shown) extending parallel to the axis of member 4<SP>1</SP> to bear via a roller (11) on the left hand end of a contoured flange 12 of the member 4<SP>1</SP>. The clockwise bias only acts to rotate member 4<SP>1</SP> into the 70% normal maximum position. If it is then desired to operate the engine only on diesel oil, handle 4 is rotated manually clockwise to move face 8 of member 4<SP>1</SP> into alignment with extension 2a. This position corresponds to normal maximum pump output. A micro-switch may be mounted in chamber 13 to automatically turn on the petroleum gas supply system when face 9 is moved into alignment with extension 2a by-the biasing device.
