Title: Humidification apparatus
Inventor: BABINGTON ROBERT STOREY
IPC: F24F6/12
Filed: 1968-04-10
Abstract: 1,220,614. Air humidifier. R. S. BABING- TON, A. A. YETMAN, and W. R. SLIVKA. 10 April, 1968 [12 April, 1967], No. 17411/68. Heading B1R. A device for humidifying air comprises a water reservoir 1, a rotatable cup-shaped wheel 27 which when rotated throws water into a trough 30, the trough having an outlet controlled by an adjustable gate 41 and supplying water to the curved surface of a tubular chamber 45 so that a film of water flows towards an orifice 50 in the chamber, air under pressure being supplied to the chamber whereby a stream of air issuing from orifice 50 atomises the water adjacent the orifice the resulting mist being discharged directly into the atmosphere or into an air duct. In a modification the chamber 45 may be boot-shaped and the trough 30 may be constructed so that excess water can readily flow back into the reservoir. In other modifications a stream of air under pressure may force water from the reservoir to a trough or a stream of air may blow water directly into the surface of the chamber 45.

Title: Apparatus for the determination of variance standard deviation and/or related values
IPC: G01B15/00
Filed: 1948-06-29
Abstract: 679,114. Electric analogue calculating systems. NEDERLANDSCHE ORGANISATIE VOOR TOEGEPAST - NATUURWETENSCHAPPELIJK ONDERZOEK, TEN BEHOEVE VAN NIJVERHEID HANDEL EN VERKEER. June 29, 1948 [July 14, 1947], No. 17474/48. Class 37. [Also in Groups IX, XIX and XL (b)] In a system for determining the variance of a series of measurements, e.g. the variation of a length of textile yarn, the measurements are made by a feeler which operates devices to modify the radiation flow, to a light-sensitive device so that the radiation passing is a square law function of the feeler movement and the effect of the light is integrated or averaged. The light-sensitive device may be a photographic plate. Applications mentioned are the examination of threads, tubes or sheets. As shown in Fig. 4 a thread f under examination operates through a feeler c, which may be electrical or optical, on a rectangular shutter b normally just covering a diamond-shaped aperture in a screen a through which light from a source L passes to a selenium cell c, the output of which is indicated on a meter d. By virtue of the shape of the aperture, the radiation is a square function of the feeler movement. The screen a is then adjusted until meter d reads a minimum when its indication is a direct measurement of the spread. Other light-sensitive devices may be used instead of the selenium cell such as a bolometer, thermo-pile or a vacuum or gas-filled photo-cell. The output of the device may be amplified. An electrostatic integrating apparatus in association with a ballistic galvanometer may be used to indicate the variance. It is also stated that a string galvanometer, a cathode-ray oscillograph, or an energy meter of the electrolytic or motor-meter type might be used. If the deviation in only one direction is required the screen may be arranged to allow light to pass when the feeler moves in one direction only.

Title: Improvements in tuning controls for radio-receiving apparatus
IPC: H03J1/14
Filed: 1937-06-24
Abstract: 482,182. Adjusting wireless apparatus; planetary gearing. FABBRICA ITALIANA MAGNETI MARELLI. June 24, 1937, No. 17650. Convention date, June 25, 1936. [Class 37] [Also in Group XXIV] Approximate tuning of a radio-receiver is effected by an operating knob through a direct coupling having considerable angular play, and fine adjustment is effected by rotating the knob in the reverse direction in the range of said angular play, the tuning element then being driven in the reverse direction through epicyclic gearing. The tuning element and the indicator therefor are driven through a cord wound round the drum part 6 of a sleeve 5, Fig. 1, which, .during approximate adjustment, is driven directly by the tuning knob 1 through a finger 7 on the knob and tooth 8 on the sleeve. For fine adjustment, the knob 1 is rotated in the reverse direction and drives the sleeve through epicyclic gearing comprising shaft 2 and balls 17 housed in holes 5<1> in the sleeve 5 and frictionally mounted between the shaft and conical rings 16, 17. The conical rings 16, 17 are resiliently mounted in a fixed cup 18 with interposed friction linings 12, 13 by a fixed ring 11, and resilient ring 14 pressed against ring 11 by fixing screws 9. The conical rings 16, 17 are stationary during fine adjustment but slip when driven by the balls 17 during approximate adjustment. In a modification, the conical bearing rings 15, 16, Fig. 3, are held together by a retaining ring 19 and pressed by a corrugated resilient ring 20 on to the balls 17. The ring 16 is integral with a hub 161 bearing on the shaft 2, the friction between the hub and shaft enhanced by the tension in the cord 21 transmitting motion to the tuning element and indicator, being sufficient to maintain the rings 15, 16, stationary during fine adjustment, although friction elements 22, 23, 24 between the hub 16 and frame 4 may also be provided to increase the resistance to motions of hub 16<1>.

Title: Hydraulic safety control for rotary gear type motors
IPC: F16H61/40
Filed: 1954-06-18
Abstract: 766,692. Rotary engines. EICKHOFF MASCHINENFABRIK UND EISENGIESSEREI GEB. June 18, 1954 [Aug. 6, 1953], No. 17956/54. Class 110 (2). A reversible rotary compressed air motor of the straight or helical gear type, forming a member of a multiple drive, is fitted with an hydraulic safety control to prevent the motor functioning as a compressor when over-ridden. The compressed air enters through an inlet 4 and is led by a distributing slide-valve 5 to either the left or right hand side of the motor gears 1, 2 which are connected via gearing to a pump 3. As shown, the pump 3 delivers liquid under pressure via a passage 8 to a piston 10 pushing it to the extreme left, uncovering a passage 11 and allowing the liquid to discharge into a reservoir 6. A ball-valve 12 closes the end of the passage 8 to the reservoir. A ball-valve 13 opens and allows the pump to draw liquid through a passage 7. If the direction of rotation of the motor 1, 2 is reversed and the motor acts as a compressor through being over-ridden the direction of rotation of the pump 3 is reversed, so delivering liquid under pressure to the left side of the piston 10 which will then move to the extreme right closing the valve 13, opening the valve 12 and reversing the liquid circulation from the reservoir. The piston 10 is geared through a shaft 22 to the slide valve 5 and will move the valve 5 to the right, so reversing the supply of compressed air to the motor 1, 2 which now functions as a motor in the opposite direction to before. Raising the shaft 22 opens a valve 23 which allows equalization of the pressure on each side of the piston 10 so that turning the lever 27 will reverse the direction of the compressed air supply to the motor 1, 2. The pistons 14, 15 of the slide valve 5 are fitted with discs 16, 17 which uncover passages 18, 19 when the motor 1, 2 is idling with the air supply cut off allowing the gears 1, 2 to circulate air almost pressureless inside the motor housing.

Abstract: 1,119,327. Control circuits for mercury vapour lamps. NUARC CO. 19 April, 1967 [22 April, 1966], No. 17979/67. Heading H2H. A control system for an air cooled electric lamp comprises means whereby the air cooling device is rendered inoperative during the warming up period of the lamp to ensure rapid warm up thereof. With switches 19 closed operation of a push-button energizes a relay 22 whereby the supply 13, 14 is applied to conductors 24, 25 to energize a mercury vapour lamp 10 by way of a transformer 26. Relays 43, 45 are energized simultaneously with relay 22 whereupon contact 43a opens to de-energize the air blower motor 12 thus allowing a rapid warm up of the lamp 10. The relay 45 is of the slow to close type the contact 45a closing after a time equal to the warm up period of the lamp. When closed contact 45a causes energization of the blower motor 12 by way of a resistor 46 so that the motor runs at a reduced speed during operation. A device 30 integrates the light output from the lamp 10 such that after a predetermined light output from the lamp contacts 31 in the device 30 open to de-energize relay 22 and hence the lamp 10. The subsequent deenergization of relays 43, 45 causes full energization of the blower motor 12 so that the lamp 10 is rapidly cooled down ready for re-starting a further period of operation when required.
