[Also in Group XL (b)] A piezo-electric pressure transducer is provided with a sealing- chamber surrounding the contact device which is connected to the piezo crystal. As shown, the piezo-electric device comprises two semi - cylindrical quartz members 1, 2 enclosed in a steel sleeve 3 which is formed at one end into a sealing diaphragm 6 which prevents the pressure being measured from entering the space between the housing 5 and diaphragm. The quartz members are placed under initial stress by a steel cylinder 4 pressed into the sleeve. Contact is made with the separating plane of the semicylindrical bars by a thin copper sheet 8 which is connected by a conductor 9 passing through a quartz tube 10 to tubular metal contact-piece 11 in which the conductor is clamped by pin 24. A further contact-member 29 conveys the charge to the exterior of the housing. Surrounding contactmember 11 and sealed in a recess in the housing 5 is a sealing chamber comprising bushes 12, 13 within which are resilient highly-insulating sealing-rings 16, 17. The bushing and sealing- rings are of truncated conical form, as shown. A spring 22 surrounding the contact-member 11 causes a slidable sleeve 19 to compress sealing- ring 17 against the bush 27. In an alternative embodiment (Fig. 2, not shown) member 11 is cut short and member 19 extends beyond the bushes to provide an end contact.

Title: Improvements in or relating to the separation of liquids
IPC: B01D17/02
Filed: 1925-07-22
Abstract: 260,045. Shaw, H. S. Hele-, and Beale, A. July 22, 1925. Separating by gravity.-A liquid mixture is caused to flow along one or more straight channels and the lighter liquid rises through a horizontal plate or plates, provided with perforations or passages forming the upper surface of the channel or channels. An inverted arrangement of the same character is used when the lighter liquid preponderates. A cylindrical vessel 2, Fig. 1, for the treatment of oily water has an inlet 3 for the mixture and an outlet 4 for the water. It is fitted with diaphragms 5 formed by perforated plates or having openings covered by wire gauze 6, Fig. 2, and the top of each of the compartments between the diaphragms is formed by a plate 7 with gauze 8. The oil separates and passing through the gauze 8 collects in a vessel 10 for discharge through a pipe 11. The gauze 6 causes the oil to coalesce as the water passes through. Heating coils may be provided. As shown in Fig. 4 the vessel 2 is divided into compartments by partitions 13, 14, 20, 21, the partitions 20, 21 being connected by tubes 22, which have perforations in their upper surfaces. Oil separating in the earlier compartments 15, 16, 17 and also that passing through the perforations in the pipes 22, is collected in the vessel 10. Water from the last compartment 25 passes through an aperture 27 to a vessel 12, fitted with a filter bed 30 and an inclined partition 33. Any oil retained by the water is arrested by the filter. Steam from a pipe 29 can be supplied to a heating coil 28 in the vessel 10 and also for cleansing purposes to the vessel 12 and the compartment containing the pipes 22. With a suitable relation between the diameter of the pipes 22 and the velocity the flow through the pipes is stated to be of stream-line character facilitating separation of the liquids. An alternative arrangement giving stream-line flow comprises flat plates arranged one above the other, alternate plates being perforated. The mixture is caused to flow below the perforated plates, the lighter liquid being led away from above them.

Title: Air motor-compressor assemblies
IPC: F25B1/053
Filed: 1958-06-13
Abstract: 883,548. Centrifugal compressors; turbines; stuffing-box substitutes. GARRETT CORPORATION. June 13, 1958 [June 13, 1957], No. 19039/58. Classes 110 (1), 110 (3) and 122 (5). An air motor-compressor assembly comprises a compressor impeller mounted on a shaft which extends into a compartment isolated from the working spaces of the impeller by a shaft seal subjected on one side to the pressure of the fluid flowing through the impeller and on the other side to the pressure in the compartment, an air motor driving the shaft, a passage connecting the compartment to the pressurized air inlet to the motor, and pressure adjusting means for adjusting the pressure in the compartment to a valve close to that on the first side of the shaft seal. A centrifugal compressor 10, Fig. 1, is driven by an air turbine 11. Air is bled from the inlet scroll of the turbine through a pipe 70 and supplied by way of a duct 55 and an annular chamber 54 to a number of cooling passages 51 to cool the bearings. The air then passes by way of an annular chamber 60 and a duct 61 to a space 62 which is vented to atmosphere through a restricted orifice 64 which maintains the pressure in space 62 at a high value. A baffle 91 ensures that the air flows over the back of the turbine rotor to cool it. If necessary, a heat-exchanger is provided in the pipe 70 to cool the bled air before use. Some of the air in space 62 leaks past a labyrinth seal 43 into a compartment 90 to make the pressure in the latter substantially equal to that in space 62. When the compressor is stationary, leakage is prevented by means of a seal 24 similar to that described in Specificatin 875,319, but when the compressor is in operation, the seal 24 is opened by means of an annular piston 25 actuated by air supplied from the duct 55. Leakage is then opposed by a rotary seal 35, Figs. 1 and 3, subjected on its outside to the pressure at the compressor inlet 20 through a passage (not shown) and subjected on its inside to the pressure in the compartment 90. The latter pressure is maintained slightly below the compressor inlet pressure by means of a regulating valve 71 in the pipe 70, to ensure that any leakage through the seal 35 is of refrigerant out of the compressor instead of air into the compressor. The seal 35 comprises a stationary ring 38, of carbon or other selflubricating material, housed in a retainer 39 and pressed against a rotor 22 by means of a corrugated spring 46. Retainer 39 is sealed to its housing by an 0-ring 40. A sealing ring 41 co-operates with a flange 42 on the turbine rotor. Specification 875,318 also is referred to.

Title: Improvements in sensing devices
Inventor: PARISH JOHN ROBERT
IPC: G06K7/06
Filed: 1967-04-26
Abstract: 1,220,062. Card readers. T. J. JOHNSON. 25 April, 1968 [26 April, 1967], No. 19278/67. Heading G4M. A card reader comprises an insulating base 2 with a plurality of conductive tracks 1 registering with rows of an inserted punched card, and an array of sensing elements 17 is traversed over the card, column-by-column, the elements 17 being raised clear of the card during each step of sensing carriage 11. A card is manually inserted at the left in Fig. 1, gate spring 33 blocking entry of an incorrectly oriented card. Entry of a card actuates a microswitch 35 to energize a motor 32 which drives feed rollers, and a solenoid 36 which raises arms 37 so that the card is driven on to base 2, hits a stop associated with solenoid 42 and rebounds against aligning edge 39. The card entry microswitch (35) is released by passage of the card trailing edge, so that arms 37 drop and actuate switches (56, 57) to initiate scanning provided the card is correctly positioned. Pulses are fed to a solenoid 6, Fig. 4, which reciprocates a rack 5 co-operating with a pawl 14 freely mounted on a spindle 12 carried beneath base 2 by sensing carriage 11 to cause step-by-step advancement of the carriage towards the card entry end of the reader. Each step movement of the carriage 11 causes deflection of a pawl 13 engaging a fixed rack 4 and fixed to spindle 12 whereby, through linkage 18, the rod 15 is rotated to momentarily lift sensing elements 17 during movement between columns. When the last column has been sensed, carriage 11 actuates a microswitch 40 to energize solenoid 42 which disengages the card stop referred to above. In addition, a further solenoid (41) (not shown) is energized to latch up pawls 13, 14. With the pawls raised, a card ejection hook associated with the latch is projected through slot 46, Fig. 1, to engage the trailing edge of the card, and as carriage 11 is spring-returned to its starting position, the card is ejected (to the right in Fig. 1). On reaching the starting position, pawls 13, 14 are released and a carriage home microswitch indicates completion of the sensing cycle. Additional tracks 50 on base 2 may be used for controlling the sensing cycle, e.g. to scan some columns at a different speed and to pause at other columns.

Title: Improvements in switching circuits comprising reverse parallel connected ignitrons
IPC: H01J17/04
Filed: 1954-07-02
Abstract: 756,220. Switching control; protective arrangements. PHILIPS ELECTRICAL INDUSTRIES, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). July 2, 1954, No. 19456/54. Class 38 (4). [Also in Group XXXVII] A switching circuit comprising two or more reverse parallel connected ignitron tubes 1, 2 and a separate fuse 8, 9 in the cathode circuit of each tube has relay contacts 17 connected in a common part of the ignition circuits of the tubes and the winding 11 of the relay connected in such manner to the cathode circuits that when one fuse 8 or 9 blows the ignition circuits of all the tubes are interrupted. This obviates any ignitron tube remaining operative to pass pulsating direct current from the A.C. supply through the lead, e.g. a transformer 19, which the circuit is controlling. The winding 11 is connected across a bridge circuit formed by resistances 5, 6, 12, 13 and the fuses 8, 9, and blowing of either fuse unbalances the bridge causing current to pass through a rectifier 7 and the winding 11 which thereupon opens its contacts 17; the latter or other contacts not shown, of the relay, may switch-off further control circuits. The common part of the ignition circuits includes a starting switch 16 and an ignitron tube cooling-water control switch 18.

Title: Improvements in or relating to aerial assemblies
IPC: H01Q1/00
Filed: 1956-06-22
Abstract: 808,961. Aerials. GENERAL ELECTRIC CO. Ltd., GRIFFITH, G. W. S., and HICKIN, E. M. Sept. 20, 1957 [June 22, 1956], No. 19488/56. Class 40 (7). An aerial assembly comprises an aerial system and a device, which does not form part of the aerial system, mounted on a mast and so arranged that the torque on the mast resulting from a cross-wind acting on the assembly is less than the torque that would result from the same wind acting on the aerial system alone. The assembly is normally designed so that the aerial system lies on one side of the mast and the device lies on the other side. The accompanying Figure shows such an assembly, the aerial system being an helical aerial 3 and a flat plate 1, and the device 7 being a planar grid of bars. Side plates 8 are shown in this embodiment and serve to reduce the torque still further for winds having a low angle of incidence on the plate 1. The Specification also describes an embodiment employing a corner reflectortype aerial system.

Title: Improvements in or relating to electric motor control systems
IPC: B60L15/04
Filed: 1928-07-05
Abstract: 319,431. Gray, W. T., and Associated Electrical Industries, Ltd. July 5, 1928. Series-parallel control systems.-Two or more groups of motors and their control switches are arranged so that the groups are normally in series with one another, and the motors in each group are capable of being rearranged in series or parallel bv a control system common to the groups. In order to suit different voltages of supply, the groups are connected in parallel with one another for the lower voltage, and in series with one another for the higher voltage. Arrangements are made whereby a group can be isolated when necessary. After one group has been isolated electrical interlocks in the control circuits prevent the remaining motors from being put in parallel connection. Fig. 1 shows the power circuits for two groups, each consisting of two motors. On the higher voltage supply the groups are in series through a switch 3, and switches 2 and 4 are open. A common mastercontrol system, preferably electropneumatic, enables the motors A<1> and A<2> to be put in series or parallel with each other through switches LS<1>, LS<2>, JR, and G; simultaneously the motors A<3>, A<4> are put in series or parallel through corresponding switches of the second group. Resistances rr<1>, rr<2>, rr<3> &c. are cut-out in steps in the usual way. On the lower voltage supply the switches 2 and 4 are closed and the switch 3 is opened to put the two groups in parallel with each other. Either group can be isolated by suitably opening or closing the switches 1, 2, and 4. To prevent parallel connection of the two remaining motors after one group has been isolated, the series-parallel master controller has its parallelling contacts in an interlocking circuit taken through auxiliary contacts of the master controller for the isolating switches. The invention is applicable to motors for traction and other purposes.
