Abstract: 1,122,243. Determining position acoustically. TEXACO DEVELOPMENT CORP. 15 April, 1966 [29 April, 1965], No. 16567/66. Heading H4D. [Also in Divisions E1 and G4] Apparatus for guiding equipment 42 during lowering from a water surface so as to enter an under water well bore 16 comprises ultrasonic frequency transmitters 27, 28 mounted on a base member 21 which surrounds the well bore 16 and an equipment carrying bracket 46 provided with receiving pods 47, 48, each having three sonic receiving transducers 51, 52, 53, Fig. 2, associated with propulsion units 56, 57, 58 respectively. Each propulsion unit is provided with a servomotor 61 and propeller 62. The speed of each servomotor 61 is proportional to the electrical input signal from its associated receiving transducer 51, 52 or 53 so that the pods 47, 48 locate and stay centred on the beams generated from the transmitters 27, 28 respectively. As shown, transmitters 27, 28 are electrically energized from a drilling vessel 11 via a buoy 31 through cables 41, 36. Cable 36 comprises a lead 34 which energizes transmitter 28 and two leads 29, 32 which energize transmitter 27. Transmitter 27 is energized through one of its leads by means of a switch (62), Fig. 5 (not shown), so that a relatively low frequency ultrasonic beam is generated. The drilling vessel is manoeuvered until a maximum in received intensity indicates that the near centre of the ultrasonic beam is detected by receiving pod 47. Transmitters 27, 28 are then switched to their high frequency ultrasonic transmitting mode and equipment bracket 46 is rotated about the axis of the beam from transmitter 27 until receiving pod 48 senses and locks on to the generated beam from transmitter 28. The drilling ship is then anchored and equipment 42 carried by bracket 46 is lowered and automatically guided along the beams towards the well bore.

The liquid detergent is supplied from a tank 24 by a pump 32 to the tank 26 through a conduit 40 and a manually adjustable valve 42 therein which bleeds-off a portion of the detergent in the conduit 40, the rest being returned to the tank 24. The hot water is supplied to the tank 26 under pressure through a conduit 48 and a valve 50 controlled simultaneously with the pump 32 by a rubber diaphragm switch 52 and rubber diaphragm overflow and underflow switches 56, (54). Depressing the first button (74) opens a valve (68) in the conduit 70 and starts the pump 64 so that cleansing liquid is supplied through the conduit 62 to the gun 60. Depressing the second button opens another valve (68) in the rinsing water conduit (72) and closes conduit (70), so that rinsing water is pumped through the conduit 62 to the grin 60. Depressing the third button (74) closes both valves (68) and deenergizes the pump 64 so that there is no flow to the gun 60. The apparatus is controlled by a timer mechanism operated by coins inserted in a receptacle 76, and controlling the power supply to a motor 66 which drives the pump 64 and to valves (68). A thermostaticallycontrolled heating element 58 is disposed in the tank 26. The tanks 24, 26 and associated ports form a supply unit (18) which is disposed within a walled enclosure 20 at one side of a self-draining still 10. In Fig. 2,(not shown), two stalls are disposed side-by-side and are supplied from a single supply unit. In another embodiment of the supply unit, Fig. 5 (not shown), two delivery pumps (71), (73) replace the single pump 64 and each is incorporated into a circuit similar to that in which the pump 64 is used. There are two separate valves (81), (83) on the cleansing liquid tank (26) to allow or prevent cleansing liquid being passed via separate conduits (74), (75) to the separate pumps (73), (71) and thence to two separate guns disposed in separate stalls. Similarly, a double valve (69) in the rinsing water conduit (49), (67) controls the flow of rinsing water via separate conduits (85), (87) to the pumps and to the guns.

Abstract: 740,844. Automatic feed weighers. SKIP COMPAGNIE GES. June 22,1953 [June 23, 1952], No. 17287/53. Class 143 In a skip conveyer installation, e.g. for transporting coal from the bottom of a shaft to the surface, the coal is first weighed in a pivoted weighing bin 1 pivoted in a frame 6 so that the bin can be swung to discharge into a skip 3 through an opening closure 2 at the base and the frame 6 is suspended from a composite weighbeam comprising two levers 8, 9 one of which carries a tare weight counterbalancing the weight of the bin and frame and the other an adjustable weight 10 for determining the weigh load. Winding tackle 11 permits the weighing lever to be lowered and rendered inoperative so that the bin and frame are wholly supported for tareing purposes by the tareing lever. The frame 6 moreover is supported for parallel downward descent:by links 5 at the base. A conveyer belt 14 charges the bin from a hopper 13 with adjustable outlet valve 16 and is set into motion by a switch actuated by the emptied bin on rising until, on the set weight being reached, the upwardly rising weighbeam switches off the conveyer belt drive. Arrival of a skip at the loading station actuates through a switch and relay a timing mechanism which stops the skip conveyer for a predetermined time, operates a pneumatic ram 4 to discharge the bin into the skip, an abutment on the edge of the skip causing the closure member 2 automatically to open, and then returns the ram to initial position. The closure member 2 runs on rollers. Single or multiple track skips may be employed.

Patent GB-442775-A (GB)
Title: Improvements in or relating to air pumps, superchargers and the like
IPC: F04B49/24
Filed: 1934-06-13
Abstract: 442,775. Air compressors; superchargers ; valves. AMERY, G., 3, Greville Road, Kilburn, London. June 13, 1934, Nos. 17498 /34 and 13533/35. [Class 8 (i)] [See also Groups XXVII and XXIX] In arrangements for compressing gaseous fluids to a desired pressure independently of variations of the supply pressure of the fluids so that, for example air can be supplied to an aeroplane engine at normal atmospheric pressure, the receiver supplying air to the compressor or to the cylinders of the engine is regulated by a relief valve which is controlled by the pressure of gaseous fluid in a chamber maintained at a constant temperature by an automatic temperature-responsive device. In Fig. 1 which shows a twostage compressor with first-stage double acting pistons on the left-hand side, air entering the inlet 37 compressed during the inward stroke of the piston is supplied past the spring- loaded valve 36 to the receiver 34 which is controlled by the automatic valve to be subsequently described. During the inward stroke of the piston, air is also drawn through the main inlet 30 controlled by the valve 31. Should the charge above the piston be at less than atmospheric pressure, the deficiency is made up from the receiver 34 through the inlet 38 which opens to the cylinder at the end of the inward stroke of the piston. The charge compressed during the outward stroke passes the delivery valve 33 into the second stage of the compressor. The automatic relief valve 40, Fig. 2, by means of which the fluid in the receiver 34 is maintained at constant pressure is in communication with a chamber 54 containing a quantity of gas which is maintained at a constant temperature by fluid circulated through the pipe 55. Should the pressure in the receiver 34 rise above normal atmospheric, the valve opens and the excess is discharged through the vent 53. The arrangement for maintaining constant temperature in the chamber 54 is shown in Fig. 4 and comprises a bi-metallic strip 86 linked up to the butterfly valve 82 which controls the supply of heating-fluid passing through the pipe 55. In a modification, increase of temperature in the chamber causes displacement of a pressuresensitive element and consequent control of supply of the heating medium. In a further modification the valve 63, Fig. 3, controlling the receiver 60 has a piston 67 opening into the chamber 68 and a shoulder 70, exposed to atmosphere through the duct 71. The space 72 beneath the shoulder is connected to vacuum through the pipe 73. In this case, the lower the atmospheric pressure, the higher will be the pressure maintained in the receiver 60. The air from the receiver 60 may be supplied directly to the cylinders of an internal-combustion engine. Specifications 14695/15,106,635, and 128,668, [all in Class 7 (iii)], are referred to.
