Title: Improvements in and relating to photo-electric cells
IPC: H01L21/00
Filed: 1952-03-20
Abstract: 704,828. Measuring radiation. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. March 20, 1952 [April 21, 1951], No. 7211/52. Class 40 (3). [Also in Group XXXVI] The light-sensitive element of a photo-electric cell is constituted by a germanium crystal which is wholly of the p-type, i.e. having a defect electron conductivity. To obtain the p-type germanium n-type germanium is subjected to a temperature of 1400‹ C. in a graphite mould and is then heated to a temperature of 1100‹ C. at a very low pressure. The p-type crystal 1 is carried by an electrode 2 slidable and adjustable in a collar 3 mounted in the wall of a cylindrical tube 4 of insulating material closed at its end by metal plugs 5, 6 carrying connecting pins 7, 8. Point-contact electrodes 10, 11 are supported by plugs 12, 13 slidable in holes in the plugs 5, 6 and connected by members 17, 18 to screwthreaded members 15, 16. An opening 9 opposite the exposed surface of the crystal 1 may be closed by a shutter acting as a filter for a predetermined spectral band. The output electrodes 2, 7, 8 may be connected to two separate indicating devices, Fig. 3 (not shown), or the electrodes 7, 8 may be connected in parallel to a single indicating device. In a further circuit, Fig. 5, arranged to restore a galvanometer to a central position, the electrode members 10, 11 are connected to the grids of two valves 22, 23 and arranged push-pull so that unequal deviation of a light-beam controlled by the galvanometer produces across a resistance in the plate circuit of the valves a controlling voltage. U.S.A. Specifications 2,504,628 and 2,505,633 are referred to.

IPC: B67D7/16
Filed: 1923-07-14
Abstract: 221,745. Chambers, C. July 14, 1923. Fixed chamber appara. tus: with several chambers; valve system for; varying quantity measured in.-The measuring chamber is constructed with a domed or conical top provided with one or more openings the edges of which form overflow weirs and may be machined or made adjustable to secure an accurate capacity adjustment in the chamber. The chamber 1 has a conical base 2 and a roof or top 3 with a conical portion 5. The inlet pipe 9 is carried up to the top of. the chamber and then is bent downward, passing through the top. Three equally spaced holes in the top are provided with necks 6 into each of which is screwed a sleeve 7 by means of which or by a similar sliding sleeve the capacity of the chamber is finally adjusted, the sleeve being then sealed. The pipe 9 is provided with an opening 10 to break a possible syphon, any discharge from the opening 10 being directed through the pipe 11 to one of the sleeves 7. In a modified form two chambers are provided, one filling while the other is being emptied. Two-way rotary valves control communication between inlet and discharge pipe. Each chamber has a conical top provided with a central neck portion. An overflow pipe leads from the annular space between the top and the cylindrical sides of the apparatus which are continued above the top 3. Specification 221,608 is referred to in the Provisional Specifications.

Title: Apparatus for dispensing towelling
IPC: A47K10/28
Filed: 1957-03-05
Abstract: 830,455. Dispensers for towelling &c. BAYLISS, G. D. Feb. 27, 1958 [March 5, 1957], No. 7226/57. Class 18. Apparatus for dispensing towelling from a continuous web of the kind having a time delay mechanism comprises a pair of vertical guides 6 between which a feed roll 7 and a rewinding roll 13 are mounted for free vertical movement, a support 10 for the feed roll 7 and a driving roller 12 mounted between the guides and bearing against the towelling on feed roll 7 and supporting the rewinding roll 13. The time delay mechanism comprises a spiral cam 18 and a spring loaded lever 19 mounted on a slide 16 which is free to move vertically. On pulling the towelling the driving roll 11 is rotated once and during the rotation the lever 19 is set, by a pin 23 on the face of cam 18, so that its nose 20 lies in the path of shoulder 21 and stops further withdrawal of towelling. A spring 22 controlled by a clockwork time delay mechanism 25 connected to lever 19, removes nose 20 out of the path of movement of shoulder 21 so that more towelling may be withdrawn.

Coal falls down open shoot 10 and is metered by means of two valves 14 operated by cylinders 18 controlled by hand control 19, there being a reversing valve 25 included in the fluid circuit which is engaged by stud 27 of the piston of the lower cylinder as the latter closes so as to then cause the upper cylinder to close the upper valve. By adjustment of valves 22, 23, 24, 26, the time-lag between the valves may be varied to predetermine the charge of coal delivered with each cycle of the valves. Alternatively, the bottom valve may be closed, and the upper valve opened and then closed before the space is fully occupied. In this way the time interval between the opening and closing movements of the upper valve is set to determine the charge of coal to be delivered. Specification 631,843 is referred to.

Filed: 1967-10-30
Abstract: 1,126,721. Windscreen washers. J. MULLER. 30 Oct., 1967, No. 80/66. Heading A4F [Also in Division F1] Automatic windscreen cleaning apparatus comprises a wiper blade 8 arranged to reciprocate across a portion of a windscreen, a nozzle 6 arranged for movement with the blade for the purpose of ejecting a stream of cleaning liquid in the form of a jet on to the said portion of the windscreen, a pump 3 arranged to supply a predetermined quantity of cleaning liquid to the nozzle 6 each time the pump is actuated and power driven means for actuating the pump at least once during each cycle of movement of the blade. The pump 3 may be provided with an electrically operated diaphragm and may be so connected through a switch arrangement to a current source which supplies the wiper motor that when the wiper blade is reciprocating across the windscreen the pump is actuated automatically once per cycle or at each stroke of reciprocation. The pump 3 directs liquid on to the wind screen in front of the wiper blade during movement thereof either by connecting the blade to two nozzles which are automatically and alternately operated according to the direction of movement of the blade (Fig. 3, not shown) or by providing a single nozzle which may be drivably connected to the wiper blade through a "lost motion" device. The "lost motion" may be provided by drivably engaging the nozzle which is mounted on a motor driven spindle with the wiper blade using a pin and slot connection (Fig. 4, not shown) or a recessed ring connection (Fig. 5, not shown) or a connection comprising two projections on a disc (Fig. 6, not shown). In a further embodiment, a nozzle pivotally mounted on the wiper blade is suitably acted upon at the limits of the reciprocal motion by fixed stops to ensure that liquid is directed on to the windscreen in front of the blade when in motion (Fig. 7, not shown).

Abstract: 1,169,114. Centrifugal strainer. J. J. SERRELL. 21 Feb., 1967 [4 March, 1966], No. 8095/67. Heading B1D. A centrifugal strainer comprises a porous, endless filtering band 15, entrained round pulleys 11-14, a nozzle 24 delivering slurry for treatment tangentially on to the band where it passes on to pulley 11, solids being discharged at 29 as the band passes round pulley 12. An arcuate tunnel in which centrifugal straining occurs is formed by an annular recess on pulley 11 (Fig. 3, not shown) or by ribs on the band and a flat pulley 11. The band may be perforated sheet, with the upstream surface sloping towards the holes (Fig. 4, not shown). A pump 21 and valve 22 deliver slurry through nozzle 24 at the linear speed of the band. Pulley 11 is driven by motor (16) (Fig. 1, not shown), and one pulley 14 is spring-loaded to tension band 15. Liquid passing through the band impinges on baffle 25 and drains from outlet 27. Advantageously, slurry is fed so as to form a less than mono-particulate layer, that is the solid particles are spaced apart on band 15, to minimise residual liquid content and facilitate passage of fines through the band. Typical speeds and delivery rates are given.
