Title: Improvements in or relating to means for converting light variations into electric current or potential variations
IPC: H01L21/16
Filed: 1930-08-26
Abstract: 361,899. Light-sensitive cells. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Siemens & Halske Akt.-Ges. ; Siemensstadt, Berlin.) Aug. 26, 1930, No. 25499. [Class 40 (iii).] In a photo-electric cell in which the photo-electric effect occurs at the contact surface of an electrode 4 and photoelectric material 1, the rectifying effect between the electrode 3 and the material 1 is small compared with that between the electrode 4 and the material 1. The material 1 preferably consists of cuprous oxide obtained by heating a copper block at about 1000‹ in an atmosphere of oxygen. The electrode 3 either consists of graphite or a graphite layer 2 may separate the cuprous oxide from a metallic electrode 3. The rectifying effect may also be reduced by sand-blasting the cuprous oxide, the graphic electrode being applied after. The other surface of the cuprous oxide is preferably etched with a mineral acid. The metallic electrodes may be deposited by cathodic atomization, electrolytically, or galvanically or by deposition of vaporized metal, and may consist of rare metals. The electrode 4 may be obtained by reducing the surface of the cuprous oxide 1 by heating it to 600‹ and then dipping it in alcohol or by an electrolytic process. The electrode 4 may be given a sharp outline by protecting the portions of the surface of the material 1 to be left free with a varnish prior to deposition of the electrode and afterwards removing the varnish, or by removing desired portions of the electrode chemically through a mask.

Patent GB-601346-A (GB)
Title: Improvements in or relating to lithium base lubricating grease compositions and method of preparing the same
Filed: 1945-10-04
Abstract: Lithium base lubricating greases comprise an oleaginous vehicle and a lithium soap, formed from either a soap-forming hydroxy fatty acid or a glyceride of such fatty acid, or of a blend of such material with a soap-forming fatty acid material not of the hydroxy type.  In the latter case the hydroxy fatty acid may comprise at least 35 per cent of the blend or the hydroxy fatty acid glyceride may comprise at least 50 per cent of the blend. The nonhydroxy fatty acid material may be a saturated fatty acid and an oxidation inhibitor may be present.  The fatty acids and/or glycerides may be saponified with a basic lithium compound at temperatures below 300 DEG  F., the soap dehydrated at 270 DEG  F. to 330 DEG  F. and the mineral oil then added.  In an example, 12 lbs. of hydrogenated castor oil, 12 lbs. of a mildly-refined mineral oil having a viscosity of 57 S.U.S. at 100 DEG  F. and 4 lbs. of stearic acid were stirred at 170-200 DEG  F. with a solution of 2.40 lbs. of 53.6 per cent lithium hydroxide in 16 lbs. of water until the fatty constituents had been saponified.  The product was then dehydrated by heating to 280-300 DEG  F., and a further quantity of the same oil added, followed by 0.35 lb. stearic acid and 0.35 lb. of phenyl alpha naphthylamine.  Addition of the oil was then continued until the grease had a worked ASTM penetration of 320 at 77 DEG  F.  It contained 14.6 per cent by weight of soap, had an ASTM dropping point of 357 DEG  F., a "Navy Water absorption" of 5, and when worked with a perforated piston in a closed cylinder for 8 hours at 225 DEG  F. at the rate of 49 strokes per minute, remained practically unchanged in penetration.  These greases when prepared with very low power point mineral oils, are adapted for the lubrication of aircraft control bearings at temperatures ranging down to approximately minus 100 DEG  F.  They are stated to have the advantages over the conventional lithium base greases that high temperatures are not necessary in their manufacture and that they maintain their structure without separation of oil and soap when subjected to prolonged shearing stresses at temperatures above atmospheric.  The oleaginous vehicle may be a mineral lubricating oil, derived from petroleum, a synthetic lubricating oil obtained by cracking and polymerization, as in the Fisher-Tropsch process, or wholly or partly a synthetic oleaginous compound within the lubricating oil viscosity range, e.g. aliphatic dicarboxylic acid esters, such as the alkyl esters of sebacic acid, high molecular weight aliphatic ethers, such as normal hexyl ether, or the alkyl esters of benzoic or phthalic acids.  The preferred oleaginous vehicle is a mineral lubricating oil viscosity 40-70 S.U.S. at 100 DEG  F., V.I. 30 or more, and having a low pour point.

Toffee is fed in a continuous sheet 11 on a continuously moving conveyer 10 and cut into transverse strips 12 by ganged knives 13 which are mounted in a frame 14 moveable transversely 'relative' to the conveyer on guides 15 on a carriage 16. This carriage moves forwardly with and at the same speed as the conveyer on longitudinal rails 17 while the cutting operation is performed ; switch 23 then being actuated to initiate the return movement of the carriage and to energize the electromagnet 18 mounted on the carriage 16 which is thus clutched to a steel strip 20 which may be a part of the conveyer or a separate strip secured to it. The electromagnet then travels forwardly with the conveyer along the tracks 19 on the frame 16 and against the action of spring 21 until it actuates switch 25 which de-energizes it, allows it to return to its initial position, and initiates the next forward movement of the carriage. A striker of adjustable length is provided on the electromagnet for engagement with the switch 25 whereby the space interval between successive cutting cycles can be adjusted.

Title: Improvements in or relating to vehicle-actuated traffic control systems
Inventor: WHITTINGTON PETER RONALD
IPC: G08G1/08
Filed: 1964-06-23
Abstract: 1,062,846. Road signals for controlling traffic. ELLIOTT BROS. (LONDON) Ltd. June 22, 1965 [June 23, 1964], No. 25984/64. Heading G4Q. A vehicle-actuated traffic control system comprises a conditional logic controller having electronic counters which operate on clock pulses derived from a reference source, which may be the 50 c/s. mains supply. On each road (phase) which does not possess right of way, a counter (10, Fig. 1, not shown), counts the number of vehicles recorded by a vehicle detector; and when right of way is accorded to a road a central controller (11) sets the minimum timer (15) in accordance with the stored count, and this timer (15) counts clock pulses upwards or downwards to a terminal number. Any further vehicles arriving on the road cause pulses to be channelled via the controller (11) to an extension timer (16). As soon as a vehicle registers a demand on another road, a maximum timer (17) is set; the green period can thus be terminated by any of the three timers (15-17) according to traffic conditions. At the end of a green period the central control (11) examines the counters on the other phases in sequence and initiates a change in favour of the next phase on which there is a traffic demand; if there is no demand no change is made. Between the green times on successive phases there are " Amber " and " Red and Amber " periods and there may be a fixed " All Red " period. In addition, there may be a variable " All Red " period adjusted according to traffic demands and an " All Red " extension time controlled by detectors in the centre of an intersection. Timing green extensions.-The green extensions may be fixed periods or may vary with traffic speed. Signals from two spaced apart vehicle detectors (21 and 22, Fig. 2, not shown), respectively start and stop the counting of clock pulses by a reversible counter (24) which is counted back to zero by clock-pulses reduced in frequency by a desired factor (in unit 30). The green extension is held as long as the counter (24) is not at zero, and therefore depends on the speed of the vehicle. The counter (24) is set to zero by a signal from the first detector (21); a parallel counter (32) is not re-set to zero, so that a faster vehicle following a slower vehicle will not replace the extension granted to the latter as the extension is not terminated until both counters return to zero.
