Title: Improvements in and relating to breathing apparatus
IPC: A61M16/00
Filed: 1937-08-03
Abstract: 482,492. Bourdon pressure gauges. DEGEA AKT.-GES. (AUERGES.). Aug. 3, 1937, No. 21421. Convention date, Aug. 15, 1936. [Class 106 (ii)] [Also in Group VI] In breathing-apparatus employing oxygen or other gas under pressure delivered through a pressure-reducing valve, warning of the exhaust of the gas supply is given by the provision, between a delivery nozzle for the gas and a whistle or other signal arranged opposite thereto, of a plate, having one or more apertures, and moved by a Bourdon tube connected to the high-pressure side of the valve, the plate normally diffusing the gas but permitting operation of the signal when an aperture in the plate registers with the nozzle. In the drawing, oxygen from a cylinder is delivered through a pipe 1 and a pressure-reducing valve 2 to a nozzle 5 arranged in a partition 5<1> in a connection 7 for a breathing bag 6. A whistle 14 is mounted on a bracket opposite the nozzle and is operated by the gas when permitted to escape through one of two slits 13 in a plate 12 which normally diffuses the gas. The plate 12 forms part of a lever 11 connected by a link 10 to a Bourdon tube 9, the tube being connected by a pipe 8 with the high-pressure pipe 1 and moving in accordance with the fall of pressure therein. The lever 11 may by pivotally mounted on a second lever rotatable about the nozzle 5 by a screw threaded rod against the action of a leaf spring in order to adjust the signal to operate at any predetermined degree of exhaustion. The plate 12 may have any number of apertures of the same or different widths to give a corresponding number of successive signals of the same or different periods. The whistle may be replaced by thin metal foil arranged to bend under the gas current and close an electric circuit including an optical or acoustic signal. Instead of the nozzle 5 the signal may be arranged to be operated by the jet of a lung operated valve 4 also mounted on the partition 5<1>.

Title: Improvements in or relating to plain bearings
Inventor: TAIT WILLIAM HENRY
IPC: F16C33/14
Filed: 1951-09-13
Abstract: 722,260. Making bearings. GLACIER METAL CO., Ltd. Sept. 11, 1952 [Sept. 13, 1951], No. 21541/51. Class 83 (2). In the production of bearing liners a strip of copper-lead or copper-lead-tin alloy with or without a steel backing is treated by chemical or electrochemical action to remove copper or copper and tin from the surface layer and the projecting lead is consolidated by a pressing operation to shape the liner to a predetermined dimension. The bearing surface after treatment for the removal of copper may be coated electrolytically with tin or indium before pressing. The liner may be formed from a strip of composition one lead two copper bonded to a steel backing of thickness ten thousandths inch oversize. The liner is suspended as an anode in a solution of 70 per cent orthophosphoric acid in alcohol and a current of 80 amps per square foot is passed for 20-30 minutes to remove copper to a depth of 15 thousandths inch. After washing and drying the liner is subjected to a pressing operation as set forth in Specifications 685,319 or 722,276 to consolidate the lead into continuous surface film about 5 thousandths inch thick.

Title: Devices for generating acoustic waves in fluids by implosion
IPC: G10K15/02
Filed: 1975-05-20
Abstract: 1478813 Implosion generator INSTITUT FRANCAIS DU PETROLE 20 May 1975 [20 May 1974] 21569/75 Heading G1G An implosion generator for use in marine seismic surveys or boreholes comprises a piston 10 slidable in a cylinder 2, 2a, and a member 6 for abutting the piston to slide it downwards to an extended position at which it is locked. Subsequent unlocking allows hydrostatic forces on piston head 24 to retract the piston rapidly, creating an implosion. The member 6 is initially moved downwards by a hydraulic system, including a second piston 5 and cylinder 1, until a flange 19 on piston 10 seats on a stop member 20. Piston 10 is then locked in this position by applying hydraulic pressure via duct 22 to the space 17 above flange 19 and establishing atmospheric pressure in the recess 21 below the flange via duct 23. Thereafter member 6 is withdrawn upwards. The implosion is initiated by pressurizing recess 21 to unlock piston 10, which accelerates upwards due to to the hydrostatic pressure acting on head 24 and to the partial vacuum existing in cylinder portion 16. The hydraulic fluid (oil) the flange 19 and a reduced diameter section 18 of cylinder portion 2a co-operate to provide a braking action on piston 10 at the end of its stroke. Piston head 24 may be mounted resiliently on the piston body to withstand implosion-generated shocks Fig. 4 (not shown).

An anti-friction bearing 10 to take end thrust is interposed between an annular shoulder in the clamping sleeve and a corresponding shoulder on the ring, and the latter is held in place by a split ring 11 engaged in an annular groove in the bore of the clamping sleeve. The collet is located in the housing by a peg 12.

Title: Elastic wave transducers
IPC: H03H9/13

Abstract: 1,036,615. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. May 30, 1963 [May 31, 1962], No. 21612/63. Heading H1K. [Also in Division H3] A transducer for deriving an electrical signal representative of the modulation envelope of an input ultrasonic mechanical wave comprises a body 17 of piezo-electric semi-conductor material to which the ultransonic mechanical wave is applied, the body having a pair of electrodes 18, 19 spaced apart in the direction of transmission of the ultrasonic mechanical wave by a distance large compared to the carrier wavelength but less than one half of the minimum modulation-signal wavelength and the conductivity of the material of the body being so chosen that an electrical output corresponding to the modulation envelope appears between the electrodes 18, 19. It is stated that the impressed mechanical wave modulates the conductivity of the material by virtue of a " bunching " in electron density arising as a result of the electric field associated with the mechanical wave, the resulting non-linearity effecting demodulation of the applied modulated waveform. In the arrangement illustrated, the output from a source 12 of high-frequency electrical carrier waves modulated by pulses or other low-frequency signals, is applied to a piezo-electric transducer 14, 15, the mechanicalwave output from which passes as a modulated ultrasonic wave down the ultrasonic delay line 13 to the demodulating transducer 17, 18, 19, the output from which is applied to utilization device 20. A further member of acoustical damping material 21 may be disposed beyond the electrode 19 to prevent reflections within the body 17. The material of the body 17 is preferably a compound taken from Groups II and VI such as CdS, CdSe or ZnS or from Groups III and V such as GaAs, InSb or InAs, doped with a suitable, preferably donor, material. Possible doping materials mentioned are Zn, Sn, S and Se. The conductivity is chosen to be in the region of its optimum value which is directly proportional to the product of dielectric constant and carrier frequency. In the case of photo-conductive materials adjustment of the conductivity may also be effected by adjusting the amount of incident light falling upon the body 17.

Abstract: 598,300. Cooling motors. ELECTRICAL ENGINEERING & MANUFACTURING CORPORATION. Nov. 6, 1944, No. 21701. Convention date, Nov. 6, 1943. [Class 35] In a motor pump unit with axially extending air ducts between the motor stator and a casing, these ducts and the fans are arranged so that air traverses some of the ducts in one direction and returns through the remaining ducts. In the form shown, the stator laminµ are square, thereby providing four segmental axial ducts between the core and the inner casing 28 and the inlets and outlets to the fan 62 are such that part of the air from the fan flows through two opposite ducts (50 and another 54 not visible) and part through the air-gap and axial ducts 65 embedded in the field windings to the other end of the motor. The air from ducts 50, 54 passes into an annular chamber 78 interconnecting all four segmental ducts and hence back through the other two ducts to fan 62, while the air from the interior of the machine is passed out by fan 86 into the chamber 78 and returns to fan 62 with the other returning air. Heat is extracted from the air by the passage of the fluid being pumped through the annular outer duct 26. Specifications 586,811 and 587,909, [Group XXVI], are referred to.
