Abstract: 766,433. Photo-electric cells. FALKEN. THAL, A., and PRESSER, H., [trading as FALKENTHAL & PRESSER KOMM.-GES.]. April 24, 1953 [May 6, 1952], No. 11312/53. Class 37. A photo-electric cell comprises three discrete layers of semi-conductor material, two of the layers being of opposite conductivity type and at least two differing in respect of the spectral position of their characteristic absorption edge which extends the response range of the photo-cell. Fig. 1 shows a photo-cell comprising a basic semi-conductor layer H1 and a layer of opposite conductivity type H3 forming a P-N junction. A third layer H2 is added which is so thin that it does not interfere with the P-N junction and also has a natural absorption characteristic differing from that of the basic layer H1, preferably towards the infra-red. The layer H3 may also be selected so that its absorption edge is nearer the infra-red region than that of basic layer H1. The layer H1 may consist of selenium; layer H3 of cadmium selenide, and the intermediate layer H2 of bismuth selenide, antimony selenide, or lead selenide, or mixtures of these to which cadmium selenide may also be added. The covering layer H4 consists of cadmium oxide, cadmium sulphide, or a metal such as platinum, silver, or gold.

Patent GB-497642-A (GB)
Title: Safety glass
IPC: C09J129/14
Filed: 1937-04-22
Abstract: The adhesive or interlayer of compound glass comprises essentially a partial polyvinyl acetal resin containing acetal groups, free hydroxyl groups, and substantially no others derived from a polyvinyl ester, e.g. the acetate having an average molecular weight of 7,000-25,000 or more and acetalized from 33 to 94 per cent with a saturated aliphatic aldehyde having 2-6 carbon atoms, the particular aldehyde, and the extent of its combination in the resin being so correlated that the resin is insoluble in water, aliphatic and aromatic hydrocarbons, and substantially insoluble in ester plasticizers at ordinary temperatures, but is compatible with substantial proportions of ester plasticizers to yield homogeneous compositions of high extensibility and resiliency and high ultimate strength.  The degrees of acetalization with the different aldehydes are quoted in the Specification and illustrated by a graph.  The plasticizer may be dibutyl phthalate, di(b -butoxyethyl) phthalate, or triethylene glycol di (2-ethyl butyrate) and may be mixed with the resin with the aid of heat or a volatle solvent or non-solvent liquid such as water, acetone, ether, or benzene.  The wet resin obtained from the reaction chamber may be mixed with the plasticizer at an elevated temperature.  The plasticized resin is sheeted by extrusion, calendering, or evaporation of a solution, e.g. on one of the glass sheets.

Title: Improvements in electrical stop motions for knitting-machines
IPC: D04B35/10
Filed: 1922-04-24
Abstract: 200,250. Imray, O. Y., (Hineline Engineering Co.). April 24, 1922. Stop-motions.-Relates to an electrical stopmotion operated by the undue tension or failure of yarn supply. A movable part 5 such as a rock shaft is provided with an upwardly extending arm 6 which bears against one side of a slidable belt-shipper frame 3 so that when an electrical circuit is completed through a magnet 22, Fig. 6, in a box 10, the shaft 5, which passes through the box, is rocked and moves the frame 3 and shifts the driving-belt on to a loose pulley. The shaft 5 is held in machine-running position by the engagement of a notch 26 in a cam 23 thereon with a projection 29 on a ,pivoted armature 28. The occurrence of a broken yarn or increased tension thereof energizes the magnet and releases the notch 26 from engagement with the projection 29. The wiring of the circuit is such that magnet remains energized as long as the defect in the yarn continues, the return of the shaft 5 to machine-starting position being thus prevented. A brake shoe 55a, Fig. 5, may be applied to the fast pulley when the shaft 5 is rocked by a spring 57<a> acting on a bell crank 47<a>. The. yarns pass from bobbins or packages on a creel frame, through slotted knot-catching discs 75, between members 38, 40 carried by a box on the top of a standard 30, and through the forks 45 of sweep arms such as 43 which are pivoted to a block 42<a> on the end of a rod 42 extending vertically from the cover 33 of the box 32. Pivoted to each arm 43 is a rod 47 the lower end of which passes through a spring 50 and through the cap 33. The tension of the yarns is individually adjusted by sliding collars 48 along the rods 47. The box 32 is provided with four mercury cups such as 52 lined with insulating material. The lower end of each rod 47 carries a yoke of silver wire &c., the ends 54, 55 may make contact with two adjacent cups 52. When a yarn becomes unduly tensioned the corresponding arm 43 is drawn down until when position B is reached the yarn starts to slip out of the fork 45, the contacts 54, 55 dipping into the mercury at the same time and completing a circuit. This construction permits of a supply of slack yarn to the needles and tends to prevent the occurence of holes in the fabric. Each yarn also passes between a frame 40 and a number of fingers 39 on arms 38 on the ends of shafts mounted within bushes such as 37 projecting from the surface of the box 32. When a yarn breaks the corresponding shaft rocks and dips contacts 61, 62, Fig. 12, at the inner end into the mercury cups, thus completing the circuit.

Title: Improvements in or relating to the production of hydrogen from hydrocarbon gases
IPC: C01B3/48
Filed: 1931-04-18
Abstract: <PICT:0366360/III/1> In the production of hydrogen by passing hydrocarbons with an excess of steam through an elongated catalytic zone, the direction of flow of the gases is periodically reversed. In the illustrated apparatus a number of reaction tubes 15a, 15b, 15c are connected at each end to three manifolds serving respectively for the admission of hydrocarbon gas (10a, 10b), the admission of steam (14a, 14b), and the removal of the reaction product (17a, 17b). The direction of flow can thus be reversed in each tube independently of the others.  The reacting gases are preheated in coils 7, 12.  The reaction product may pass through a second catalytic stage 19 for the conversion of carbon monoxide to dioxide.  The invention is particularly applicable to the treatment of gases containing unsaturated hydrocarbons, such as refinery or natural gas.  The preferred catalyst is nickel or nickel oxide with or without alumina, thoria, &c.

Filed: 1968-03-11
Abstract: 1,172,942. Master cylinders; pistons. ALFRED TEVES G.m.b.H. 11 March, 1968 [23 May, 1967], No. 11723/68. Headings F2F and F2T. In a master cylinder for a brake system, wear on the piston seal 11 due to its passing over the compensating bore 27, is equalized over its entire circumference by arranging for the piston to be rotated slightly about its longitudinal axis during movement of the pushrod. In one arrangement, Fig. 1, tongues 6, 7 co-operate with teeth 9 on the piston to rotate the piston slightly as the tongues are flattened against the cylinder end wall by the piston returning to its inoperative position. In another arrangement, Fig. 7, the end of the pushrod 1 is enclosed by a member 16 which frictionally engages the piston 2 when the slack S has been taken up and is rotated by the torque produced by compression of a spring 17 the ends of which are rigidly attached to the pushrod and the member 16 respectively. In a modification, Figs. 8 and 9 (not shown), the rotation is produced by a pin (21) through the pushrod engages axially inclined slots (22) in an enclosing member (19). In another arrangement, Fig. 6 (not shown), the pushrod carries a screw having a long lead of thread to produce the rotation.

Title: Improvements relating to devices for packing machines with rotating shafts, particularly those adapted for delivering gases and vapours
IPC: F04D29/10
Filed: 1926-05-05
Abstract: 253,086. Akt.-Ges. der Maschinenfabriken Escher, Wyss, et Cie. June 6, 1925, [Convention date]. Stuffing-boxes, substitutes for; connected to source of high pressure; draining.-In devices for packing rotary shafts, particularly applicable for the shafts of rotary compressors, a pump supplies liquid to a chamber surrounding the shaft, the liquid escaping to a chamber in the interior of the machine and to a chamber open to the atmosphere, the level in the latter chamber being controlled by a float-operated valve. The liquid may be a lubricant and may be supplied by the pump to the bearings also. A pump 9, Fig. 1, circulates oil from a chamber 12, open to the atmosphere, to a chamber 10 surrounding the shaft, a second chamber 20 being supplied by a pump 7 in a chamber 6, connected with the interior of the machine. The oil escapes along the shaft to the chamber 6 and to the chamber 12 by a pipe 11. A balance is maintained by means of a chamber 15 communicating with the chamber 12 by a pipe controlled by a float-operated valve 17. In a modification the pump 7 is dispensed with, excess oil in the chamber 6 passing to the chamber 12 through a pipe controlled by a float-operated valve. In a further modification the pump 9 and an external pump drawing oil from the chamber 6 discharge through a common pipe to the chamber 10, a branch pipe discharging excess oil to the chamber 12 under the control of a float-operated valve. Alternatively the pump 9 and the pump drawing oil from the chamber 6 supply separate chambers in the packing box. In this case excess oil passes from the discharge pipe of the second pump to the chamber 6 under the control of a float-operated valve, while the suction pipe of the pump 9 is controlled by a downwardly operating float valve in the chamber 12 which closes when the level in the chamber 12 falls. The pump 9 may draw from a casing 29, Fig. 7, supplied with oil from the chamber 6 and from the chamber 12 under the control of an oscillating valve 17 operated by a float. Oil escaping back to the chamber 6 passes below the level of the oil in the chamber by a pipe 32. The pumps may be replaced by a screw 9, Fig. 4, on the shaft which discharges oil towards the chamber 6. The chamber is under pressure and discharges oil by a pipe 22 to the chamber 10, excess oil passing to the chamber 12 under the control of a float-operated valve 17. In a modification the shaft has two screws of opposite hand which draw oil from the chamber 12 and discharge it along the shaft towards the chamber and towards a passage leading to the chamber 12. The chamber 6 communicates with the chamber 12 through a passage controlled by a float valve.

Title: Lubrication Systems for Plain-Bearing Assemblies
Inventor: VOSE JOHN KENNETH
IPC: F16N29/02
Filed: 1968-03-12
Abstract: 1,198,762. Lubricating; valves. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 4 Feb., 1969 [12 March, 1968], No. 11884/68. Headings F2A and F2V. A lubricator for a plain bearing comprises a primary lubrication system supplying lubricant from an external source under pressure to the bearing, and a secondary system comprising a disc member which raises lubricant from a main reservoir to an auxiliary reservoir whence it is supplied to the bearing, there being a valve provided between the main reservoir and the disc which is closed by the pressure of lubricant in the force-feed system and opened when the primary system is not functioning. In the illustrated embodiment, lubricant passes from the main reservoir 9 through ports 10 to the disc 7 which raises the lubricant to the auxiliary reservoir 14 whence it flows under gravity through passages 15, 16 and 17 to the bearing and flows out at the end of the shaft bearing back to the reservoir 9 or the chamber 20 containing the disc. Lubricant is fed under pressure via passages 34, 35 to the passage 16 and thence to the bearing. A valve 36 is provided in the passage 15 which is closed by the pressure of lubricant in the passage 16. If the presure in the primary lubrication system fails, the valve 36 opens and lubricant passes from the auxiliary reservoir to the bearing. When a high lubricant pressure prevails in the passage 17, i.e. when the primary system is operating, pressure is built up in passage 52, which communicates with the passage 17, and thence via passages 53, 48 and 46 causes lubricant to flow into chamber 47 and move piston 43 so as to close the ports between the main reservoir and the disc chamber. Arcuate gutters 39 which are provided with by-pass holes 41 are provided to divert a large portion of the lubricant issuing from the end of the bearing through channel 18 into the reservoir 9. Valves.-A piston 43 disposed in an annular cylinder 44 is biased against one end of the cylinder by a spring 45. A tube 46 extends through the piston to a chamber 47 and communicates at the other end via passages 48, 52 and 53 with the lubricant at the bearing surface to the pressure of which the valve is responsive. When a high lubricant pressure prevails at the bearing surface lubricant passes into the chamber 47 and raises the piston 43 until it abuts the stop 51 thereby closing the port 49 and stopping the flow of fluid from the reservoir 9 to the disc chamber 20.
