Title: Friction clutch
IPC: F16D13/08
Filed: 1933-06-20
Abstract: 410,627. Friction clutches. SCHKOMMODAU, F., 209, Bachemerstrasse, Lindenthal, Cologne, Germany. June 20, 1933, No. 17598. Convention date, Dec. 10, 1932. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 27, 1933.] [Class 80 (ii).] A friction clutch comprises one or more loose split friction rings r which surround split rings h rotating with a-sleeve d keyed to the driving shaft a and adapted to be expanded by a longitudinally-slidable wedge i, engaging between the split ends of the rings h, so as to expand the rings r into contact with a driven drum k, a helical spring o having one end p pivotally secured to the sleeve d while its other end o<1> is engaged by an abutment r<1> on the adjacent ring r. The arrangement is such that, on actuation of the wedge i, the rings r expand to take up the drive. When the friction between the end ring r and the drum. reaches a predetermined value, the abutments r<1> causes the helical spring o to unwind into contact with the drum and participate in the drive. The wedge i, actuated by a collar m splined on the shaft a, may engage the split ends of the rings h through loose shoes, and has a parallel-sided portion g engaging a longitudinal groove in the sleeve d. According to the Specification as open to inspection under Sect. 91, the helical spring o and the loose rings r may be omitted, the rings h coacting directly with the drum k ; the wedge i may be arranged to act radially, or may be of stepped formation so that the rings h may be expanded successively ; or the arrangement may be such that the rings h are carried by the drum k and are adapted to be contracted into engagement with the sleeve d by a wedge. This subject-matter does not appear in the Specification as accepted.

Title: Fire fighting branch pipes
IPC: B05B1/30
Filed: 1973-04-12
Abstract: 1442203 Valves CHUBB FIRE SECURITY Ltd 3 April 1974 [12 April 1973] 17627/73 Heading F2V [Also in Divisions B1-B2] A fire-fighting nozzle, for discharging firefighting liquid supplied via a connection 2, Fig. 1, comprises a tubular body 1 having a shutoff valve comprising respective fixed and movable valve members 18, 20, the valve member 20 being movable between a closed position and an open position under the control of a manually operable pilot valve 33, the movement of member 20 being restricted by a dash-pot to limit the rate of movement from the open to the closed position. Valve member 20 is tubular and has a radially extending flange 21 slidable within a cylinder 22, the liquid flowing through the central bore of member 20 in the open position; in the closed position, a sealing washer 29 on valve member 18 abuts a notched seating ring 28 on valve member 20. The dash-pot is constituted by flange 21 and cylinder 22, ports 27 in the wall of member 20 and a labyrinth gland 26, closing the downstream end of cylinder 22, allowing a slow leakage of liquid out of cylinder 22 when the valve member 20 is moved therealong in either direction, the dash-pot thereby being double-acting. In order to close the shut-off valve, pressurized liquid, flowing to the pilot valve 33 from upstream of the valve member 20 through a tube 32, Fig. 2, in a handle 36, is allowed to flow through the pilot valve and a tube 34 to the space on the right hand side of flange 21; the force exerted on flange 21 being greater than that on seating ring 28 causes valve member 20 to move leftwards and close the shut-off valve. The pilot valve 33 is operated by a rotatable twist grip 37, spring-biased to the open position whereby flow through the shut-off valve is interrupted in the event of the handle being released. When the pilot valve is closed, liquid pressure on the seating ring 28 causes valve member 20 to move to the right, opening the shut-off valve. The pilot valve 33 comprises a tubular valve body 39 within the handle 36, tubes 32 and 34 terminating in a seat in body 39, which seat can be closed off by a sealing washer 54 carried on a plunger 42 reciprocable in a bore 41 in body 39. Rotation of the twistgrip 37 causes plunger 42 to rotate in its bore by the action of a pin 45 passing through a transverse slot 46 in handle 36, the pin 45 being secured to the twist-grip 37. A pin 48, projecting inwardly from the bore 41 and engaging an inclined groove 49 in plunger 42, converts the rotary motion of plunger 42 into reciprocation, groove 49 being parallel to slot 46. The twistgrip is biased to the open position by a torsion spring 50.

Title: Improvements in or relating to the manufacture of phosphorus
IPC: B01J8/12
Filed: 1932-06-22
Abstract: <PICT:0395865/III/1> p  In the blast-furnace production of phosphorus, the stock in the furnace is maintained in a compact condition during the combustion of the carbonaceous part of the charge by causing, at intervals, a rapid downward movement of the charge which is maintained stationary during these intervals.  The rapid downward movement is effected by checking the blast, preferably at regular intervals. Other factors in obtaining the increased compactness are use of smaller particles in the charge, e.g. smaller coke is employed, and the use of a modified construction of furnace in which the batten in the part 8a of the stack is reduced and a portion 8 directly above the bosh 6 has substantially vertical walls. In operation, the furnace is charged with small briquettes of phosphate mineral, siliceous material and coke in the proportions described in Specifications 342,559 and 395,844 and the blast is slackened at preferably regular intervals e.g. once per hour, the result being that the charge descends rapidly and becomes compacted; slag is preferably tapped just before the blast is checked.

Title: Proximity sensors
IPC: G01C3/00
Filed: 1974-04-24
Abstract: 1462504 Proximity sensors INTERNATIONAL BUSINESS MACHINES CORP 24 April 1974 [12 June 1973] 17824/74 Heading G1A The distance of an object from a measuring head (proximity) is determined by utilizing two detectors arranged to receive light reflected from the object and produce outputs one of which is relatively insensitive to the distance of the object and the other of which is more sensitive to this distance and comparing these outputs using two amplifiers one of which is of adjustable gain and a voltage comparitor producing a digital output. As shown, Fig. 1, the object W is illuminated by a LED 18 and the reflected light received by two detectors 14, 16. The angle between the optical axes of the LED and detector 14 is small and this results in an output which is relatively insensitive to variations in the object distance whereas the larger angle between the axes of the LED and detector 14 results in an output which varies to a greater extent with variations in the object distance. The signals are applied to amplifiers which are adjusted to give equal outputs when the object is at a selected distance Do and a comparitor 24 produces a two-state output according to whether the object distance D is greater or less than Do.  A circuit is given, Fig. 3 (not shown) in which the detectors are photo-transistors and the bias voltage applied to detector 14 is adjustable to provide an offset control. The circuit is set up first using a highly reflective object at distance Do and adjusting the gain of amplifier A for equal outputs and then using a low reflectivity object and adjusting the offset control to restore balance. This process if repeated several times so that the balance condition is independent of the object reflectivity.

Title: Method and apparatus for optically projecting electron images
IPC: H04N5/74
Filed: 1951-07-31
Abstract: 729,546. Cathode-ray tubes. FRIES, G., and INGLESBY, J. C. VREDENBURG-. July 29, 1952 [July 31, 1951], No. 18118/51. Class 39 (1). A photo-electron image is concentrated onto alkali halide crystals on an endless movable film or disc through which light is thrown to give a visible picture. An electron beam is concentrated onto a different part of the film or disc to remove the electric charge on the crystals. Light from a lamp 25 is concentrated by the condenser 26 through a sensitized part 4 of the disc 1 and the lens 27, and is then reflected by the mirror 29 onto the translucent screen 30, or by rotation of the mirror by a knob 32 onto the reflecting screen 35. The band 1 is driven in a discontinuous manner by a motor 14 through a worm wheel 15, gear wheel 16, the rotatable pin 17 and Maltese Cross 18 which is fixed to the shaft 13. The light beams from the reflector 36 and the lamp 25 can be interrupted by mechanical shutters. Alkali halide is vapourdeposited in discrete parts 2 on the lower side of the glass or mica disc and the image from a cathode-ray tube 43 is concentrated by lenses 37, 38 onto the photo cathode 21. The photoelectrons are concentrated by the electrodes 22, 23 onto an image sector 2. The electron lenses may be electrostatic, magnetic or electromagnetic. For the projection of a coloured image filters 11, 12 are fixed to the shaft 13. The sectors are coated with chloride of sodium, lithium, potassium or rubidium, the bromide of sodium or potassium, the fluoride or iodide of potassium to give red, blue and green filters, and are provided with a protective layer as described in Specification 715,480. The disc can be moved continuously, and the electron image may then have a similar movement of translation. Alternatively, a sensitized film can be carried in a step-wise manner through a Lenard window in the cathode-ray tube 43. The image carrier 1, when constructed as a flexible film, can have the different parts which are exposed to the light and electron beams moved at different rates or intermittently. For the production of colour prints, the sensitized plates are arranged at the parts 30, 35; a cathode sensitized with caesium is preferable. X-rays, heat radiation, such as that from the human body or an engine, and infra-red radiation can be recorded onto a cinematographic film or a screen. The infra-red rays or the light rays from a mirror telescope are reflected onto the photo-electric cathode by a mirror which is mountable in gimbals.
