Title: Process for tanning skins or hides with mineral tanning agents and protein condensation products
IPC: C14C3/02
Filed: 1953-07-10
Abstract: Condensation products of (a) proteins with fatty acids, or (b) protein degradation products with high molecular weight carboxylic and/or aliphatic or aromatic sulphonic acid halides or (c) ethoxylated derivatives of (a) or (b) or the proteins or protein degradation products from which they are derived are used with other agents in tanning.  The condensation occurs in aqueous solution in the presence of acid-binding agents, e.g. a protein condensation product may be produced by the reaction in alkaline solution of a higher fatty acid halide with a protein, or of a higher fatty acid or resinic acid halide with a higher molecular weight protein cleavage product, separated as an oil, which is dried; the resulting material may then be heated for four hours in an autoclave at a pressure of two atmospheres at a temperature of 150 DEG  C. with twice its quantity of ethylene oxide.  The presence of salts of chromium, aluminium, &c. does not disturb the condensation.  In addition to material specified in the following examples, the Specification refers to the use of fatty (oleic, ricinoleic), resin and naphthenic acid halides and sulphonic acid halides preferably having about 10 to 20 carbon atoms in the molecule.  The preferred degradation products contain 3 to 10 peptide links per molecule and may be produced from leather waste &c. containing collagen by means of aqueous hydrochloric or sulphuric acid or with lime.  In the examples, condensation products are prepared from (1) lime-degraded chrome-tanned leather and soya fatty acid with subsequent ethoxylation; (2) casein and palm kernel fatty acid, with subsequent ethoxylation; (3) casein and coconut oil fatty acid; (4) lime-degraded chromeleather waste and dodecyl benzene sulphonic acid, with subsequent ethoxylation; (5) limedegraded chrome-leather waste and soya oil fatty acid chloride; (6) lime-degraded chromeleather waste and arachidic acid; (7) limedegraded chrome-leather waste and stearic acid, with subsequent ethoxylation; (8) chromeleather waste degraded at 95 DEG  C. with hydrochloric acid and neutralized with aqueous sodium hydroxide and soya fatty acid chloride; (9) ethoxylated sulphuric acid-degraded chromeand alum-tanned leather waste and dodecyl benzene sulphonic acid chloride; (10) sulphuric acid-degraded alum-tanned leather waste and soya fatty acid chloride. It is stated that the condensation products may form soap-like precipitates with the salts of tanning metals (Cr, Al, Fe, Zr, Ti and rare earth metals).

Title: Improvements relating to electric signalling installations for vehicles
IPC: B60R16/00
Filed: 1927-07-20
Abstract: 275,218. Soc. Anon. du Cligno-Signal. (Assignees of Schott, A., Cuendet, R., and Besson, R.). July 30, 1926, [Convention date]. Switches, actuating ; ratchet actuation ; retarding devices ; momentarycontact switches; retractive switches with h compound movement. Relates to a signalling installation for vehicles. A single actuating lever 92, 93, pivoted on a shaft 58, carries a toothed sector 61 which engages a wheel 62 loose on a shaft 59. The wheel 62 carries a ratchet 63 the pawl 64 of which is pivoted on a wheel 66 on the shaft 59, the wheel 66 engaging on the one hand with a wheel 68 on a shaft 69 carrying an insulating cam 53, and on the other hand with the driving wheel 67 of a retarding device which may be a fly-wheel, shown diagrammatically in Fig. 3. The part 93 of the actuating lever is pivoted on a pin 94 in the part 92 which carries an insulating support 95 for three terminals 96 - - 98. The part 92 has three notches 99 corresponding to the three terminals so as to retain the part 93, by means of a spring-pressed ball 101, in the position to which it is set. The part 93 carries the contact arm 102 and also two arms carrying rollers 107, adapted, when the part 93 is moved to one side or the other, to engage the casing 108, the latter having guide surfaces to return the part to its median position after operation. In operation, the device 92, 93 is moved downwards, Fig. 1, and the sector 61 allows the contacts 103, 104 to close so making the circuit for the signal corresponding to the position of the part 93. When the device 92, 93 is released, the spring 70 restores it to its original position slowly, under the retarding action of the fly-wheel, and at the same time the ratchet 63 rotates the shaft 59 so that the cam 53 allows the circuit through the signalling lamp to be repeatedly made and broken at the contact blades 51, 52 until the original position is reached. The switching movement laterally by the device 93 and the vertical movement of the device as a whole take place simultaneously, and the arrangement allows the substitution of an incompleted signal by a fresh one. The movements of the part 93 can be controlled by shaping the opening in the casing 108, and the opening can be closed by sliding pieces moving simultaneously with the actuating lever. During the return movement, the contacts 103, 104 are arranged to be separated before the part 93 is restored to its original position.

Abstract: 1,176,238. Moulding olefin polymer foams. BADISCHE ANILIN- & SODA-FABRIK A.G. 27 April, 1967 [28 April, 1968; 23 Aug., 1966], No. 19431/67. Heading B5A. Mouldings of expanded olefin polymers are formed by heating expanded particles of crosslinked crystalline homo- or co-polymers of olefins having two or three carbon atoms in a closed mould from which gases and liquid can excape but from which the expanded particles cannot escape. The particles are preferably compressed by 5-70 degrees volume per cent by moving two opposed mould sides towards the centre of the mould cavity. The polymer must have an X-ray crystallinity greater than 25% at 25‹ C. and may be polyethylene, polypropylene, a copolymer of ethylene and propylene or a copolymer of ethylene with various vinyl compounds especially acrylic esters. It may contain fillers, reinforcements, dyes, flame retardants, lubricants or other polymers and the degree of crosslinking may be increased by irradiation with X-rays or an electron beam. The expanded particles preferably have diameters of between 3 and 40 mm. Heating during the moulding process may be carried out by immersing the mould in a bath of liquid, by passing a heated gas through the mould or by introducing a heated gas into the mould cavity, the pipes being removed before compressing the particles.

Title: Mechanical seal
IPC: F16J15/38
Filed: 1960-06-02
Abstract: 895,408. Stuffing-box substitutes. CHESTERTON CO., A. W. June 2, 1960 [Oct. 8, 1959], No. 19481/60. Class 122 (5). A mechanical rotary shaft seal for containing a pressurized fluid in a housing comprises a rotatable ring 32 fast on the shaft, a non-rotatable ring 58 longitudinally movable on the shaft, opposed sealing faces 46, 62 on the two rings, spring means 72 for applying a fixed resilient force to urge the sealing faces into sealing engagement, means responsive to the pressure of the fluid to urge the sealing faces into sealing engagement, and means for eliminating spring pressure when the force applied by the fluid exceeds the fixed force. The ring 32 is fixed on the shaft 10 with an intervening sealing ring 44 and the non-rotatable ring 58 is carried by a holder 48. One or more springs 72 are mounted in pockets 70 in an end wall 68 of the housing 16 and, when the fluid pressure is low, urge a piston member 74 into contact both with the holder 48 and a sealing ring 66 disposed between the housing and the holder and so force the sealing faces 46, 62 into sealing engagement. The pressurized fluid to be sealed passes from an annular space 38 surrounding the ring 32 to an annular space 64 surrounding the ring 58 and thence through a narrow annular passage 54 to an annular space 50 disposed between the sealing ring 66 and a flanged portion 52 of the holder 48; the area 51 of the flange 52 in the space 50 is greater than the area 53 in the space 64. As the fluid pressure increases in the space 50, the ring 66 is forced against the piston 74 which is then driven to the right until it contacts the shoulder 68 and so overcomes the spring force. The net fluid force acting on the areas 51, 53 urges the holder 48 and ring 58 to the left into sealing contact with the ring 32. The area of the sealing face 62 may be smaller or larger than the differential area of the faces 51, 53 and be so chosen as to allow a small flow of fluid between the faces 46, 62 for lubricating purposes. The pressure surfaces 51, 53 need not be normal to the shaft and the flange 52 could be extended to form part of the sealing face 62, the ring 58 and holder 48 then being integral. The housing 16 consists of two spaced and interfitting parts with a gasket 24 between them.

[Also in Division H2] An arrangement for storing and displaying data relating to company stock prices comprises a manually operable stock selector device including switch means for establishing signal combinations identifying the required stock. The arrangement is adapted for use with the system described in Specification 1,005,567. As described, a manually operable console comprises four rotatable stock-selector wheels 10, 12, 14, 16 each rotatable to any one of 28 rotary positions corresponding to the code for the required stock. Each wheel 10-16 comprises five code discs 38, each disc, as for example that shown in Fig. 9a, comprising a circumference having relatively high and low parts and adapted to co-operate with a microswitch 78. A group of five microswitches 78 is positioned under each unit 10-16 of five discs 38. In operation, the required stock code is selected and one key of a group of selector keys 18-26 is depressed to select the category of data required (e.g. high price, low price &c.) thereby pivoting counterclockwise a pan 72 to move the microswitches 78 into operative position, in which the pan is latched by plates 66. The selected stock identification code is transmitted as a combination of electrical signals via the microswitches 78 to a control logic circuit 204, Fig. 15, where the code is compared with signals read from the stock identification code bin 206 on a drum memory 202. When coincidence is obtained, the required information is read out to registers 214 which are connected to decoding relays 216 so that the selected data is displayed as a three-digit decimal number by indicating tubes 218 visible through windows 30, 32, 34, Fig. 2, in the console. A plurality of separate consoles may be connected to the same memory 202. In a modification (Figs. 10-14, 16, not shown), the code discs 38 and microswitches 78 are replaced by electrically conductive bands containing holes, a combination of holes and the absence of holes corresponding to the stock codes, wiper brushes being provided to co-operate with the conductive bands. The holes contain plastic plugs to form a flush surface for the wiper brushes.
