Title: Detergent compositions
IPC: C11D3/06
Filed: 1964-03-12
Abstract: A detergent composition comprises (a) at least one fatty acid alkanolamide, suitably derived from a C12-18 saturated or unsaturated fatty acid but most preferably from one containing 12-14 carbon atoms and (b) at least one alkanolamine phosphate, the weight ratio (a) to (b) generally being 9:1 to 1:9 but most suitably 2:1 to 1:2.  In both (a) and (b), the alkanolamine employed is preferably mono- or di-ethanolamine or mono- or di-isopropanol-amine. A further detergent, especially an anionic detergent such as coco-alkyl sulphate, may also be added.  The composition may be prepared directly by condensing a fatty acid (or an ester thereof) with excess alkanolamine and adding phosphoric acid to the mixture to bring the pH to 6.5-7, additional alkanolamine being added, if desired, before neutralization. The product obtained is generally a paste or cream.

Abstract: 1,075,735. Flash evaporators; desalination of sea water. WESTINGHOUSE ELECTRIC CORPORATION. March 10, 1966 [April 16, 1965], No. 10534/66. Heading B1B. The final stage D of a multi-stage flash evaporator 10 is divided into two sections 66 and 67 by a weir 65 such that pre-treated make up solution fed to section 67 for deaeration is not withdrawn from section 66 with the blowdown but is all circulated through the evaporator stages with the portion of the enriched solution which has not been blown down from section 66. Solution, e.g. sea water, is pressurized by pump 49 and is heated in passing through heat exchanger 48 in the evaporation section 28 of stage D. After rejection of some of the heated solution the remainder passes to vessel 53 for pretreatment with a chemical additive (e.g. sulphuric acid), for preventing corrosion and/or scaling and is then sprayed into section 67. The weir height is such that no make-up solution can penetrate into section 66 but enriched solution is able to spill over into section 67, the mixture therefrom being circulated by pump 73 through condensing coils 45-47 and heater 57 to stages A-D. Incondensible gases are vented at outlet 78.

Filed: 1963-03-18
Abstract: 1,011,602. Teaching apparatus. LAMSON TECHNICAL PRODUCTS Ltd. June 18, 1964 [March 18, 1963], No. 10561/63. Drawings to Specification. Heading G5R. Teaching apparatus comprises means to playback information and questions recorded on a tape (Fig. 1, not shown), ancillary apparatus such as a teaching machine as in Specifications 983,165 and 983,166 (Fig. 2, not shown) to prevent additional information to the student, control means to start the tape running until it senses a control marker on the tape and means to prevent operation of the ancillary apparatus when the tape is being fed. The tape recorder is controlled by a solenoid operated pressure roller which presses the tape against a capstan and lifts the brakes. Each tape reel has its own drive motor so that the tape is kept taut. The sensing head on the tape recorder is either a pair of brushes contacting a conducting strip or a single brush contacting a conducting surface through a hole in the tape. There may be separate sensing heads with separate markers on different channels for each direction of motion. Switches on the teaching machine permit its information web to be run in either direction and permit the tape recorder to be run in the same direction as the web. The web on which answers are written can only be moved forwards. The circuit (Figs. 3 and 4, not shown) includes a transistor hold-on circuit for the relay which prevents the teaching machine being moved while the tape recorder is playing.

Title: Step-by-step feed system for photocopying apparatus
IPC: B65H23/188
Filed: 1964-03-12
Abstract: 1,008,669. Photocopying apparatus. GRETAG A.G. March 12, 1964 [March 12, 1963], No. 10561/64. Heading G2A. A photocopying apparatus has a step-by-step feed system for the copying paper in which the length of paper advance can be adjusted to conform with the picture size; a marking device marks the paper at the edge of the picture area, and a sensing device terminates the paper advance by sensing this mark. In the form shown, the copying paper passes from a supply drum 1 over rollers 2, 3, past a picture aperture 11 defined by a mask 12,13, 14, and over roller 4 to a take-up drum 5. The parts 13,14 of the mask are adjustable in the direction of arrows h, i, and j, k, to vary the size of the picture aperture. A marking device 20 is provided which comprises a printing stamp 23 and inked ribbon 24, and which is operated by a solenoid 21 to stamp a mark M on the copy paper just behind the rearward edge of the picture area. The mark is made just as the motor drive for the paper advance is started. At the other side of the mask is a sensing device 30 comprising a light source 31 and a photodiode 32. These are so disposed that when the mark M reaches the other side of the mask aperture, it arrives at such a position that it reflects light from source 31 to the photodiode 32. An electrical impulse is thus generated which interrupts the paper feed. It is preferred that the printing ink forming the mark M is infra-red absorbent, so that the current impulse generated by the diode is due to a reduction of light incidence. The righthand side of the Fig. shows the electrical circuit by means of which the operations are controlled; the starting key 51 can be manually or automatically released. The adjustable mask part 13 is coupled to the marking device 20 so that the two can be moved together. The mask part 14 is similarly linked to the sensing device 30. Thus if, for example, the two parts 13, 14 are pushed closer together to reduce the format, the stamping and sensing devices are moved closer together to the same extent.

Abstract: 1,211,663. Electroluminescence. INTERNATIONAL BUSINESS MACHINES CORP. 28 Feb., 1969, No. 10802/69. Heading C4S. [Also in Division H1] A semi-conductor device with plane electrodes is mounted between two rigid blocks which together form a heat sink for the device and which have plane surfaces in contact with the electrodes; the two blocks are held together, by an insulating bonding material between them. The embodiment shown is an injection] laser, consisting of two PN diodes in a single semi-conductor body 22; these are connected in parallel by the upper block 12B. The blocks, which are provided with grooves 14A to allow the egress of light, may consist of molybdenum, copper, silver or tungsten. The bonding material 30, 32 may be any thermoplastic, or thermosetting material; black wax and glycol thiolate are mentioned but epoxy resin is preferred. To assemble the structure the contact surfaces of the laser and blocks are indium coated, the lower block 12A with the semi-conductor body and uncured epoxy resin thereon is placed on a rigid table, andthe upper block 12B put on initially on aslant so as to rest on one diode portion only-a stylus is then used to apply pressure directly downward on the mid-point of the block to rotate the upper block into full contact with the upper surface of the semiconductor body; this ensures that uniform pressure is applied across the body even it its surfaces are not parallel. Sufficient pressure is applied to form cold-pressure bonds. The epoxy resin is then hardened; it contracts slightly as it does. and maintains pressure in the completed device. (The intensity and frequency of emitted light is stated to be pressure and temperature dependent).

Title: Improvements relating to the neutralization of sulphonated organic products
IPC: C07C303/44
Filed: 1951-05-09
Abstract: Synthetic detergents substantially free from inorganic salts are prepared from an acid mixture containing an organic sulphonic acid or sulphuric acid ester yielding a detergent on neutralization, and excess sulphonating agent, by establishing a solvent solution containing water and a water-miscible aliphatic alcohol, feeding thereinto a stream of the acid mixture and a separate stream of neutralizing agent while controlling the reaction temperature so that it does not exceed 150 DEG  F., the amount of alcohol being small but sufficient to cause the formation of two immiscible liquid layers and the rate of feed of the neutralizing agent being so proportioned to the rate of feed of the acid mixture that the resultant reaction mixture remains substantially neutral, the amount of solvent solution being such that one of the liquid layers contains substantially all of the neutralized detergent acid or ester dissolved in the organic solvent and the other liquid layer contains substantially all of the neutralized excess sulphonating agent dissolved in the water, and separating the two liquid layers.  In general, a solids concentration of about 15-40 per cent. of the water is employed. There may thus be neutralized sulphuric acid esters of monoglycerides of higher fatty acids and sulphated higher fatty alcohols.  The process may be operated batchwise or continuously. Suitable apparatus is illustrated (not shown).  In examples (1) and (2): an acid mixture of sulphuric esters of monoglycerides of coconut oil fatty acids and sulphuric acid and an aqueous solution of ammonia are both gradually added to a stirred mixture of water and ethanol containing a little ammonia and the reacted mixture allowed to settle whereupon a lower aqueous layer of ammonium sulphate is separated from the upper 50 per cent. alcoholic solution of detergent which may be used in shampoos, cosmetics or dental creams; (3) the same acid mixture and aqueous caustic soda are similarly run into a stirred mixture of water and isopropanol and the resulting alcoholic upper layer distilled to separate the alcohol from the neutralized detergent.  Specification 666,206 is referred to.

April 12, 1933, No. 10951. Convention date, April 13, 1932. [Class 36.] A metallic member is joined to an insulating or organic member by coating the non-metallic member with a difficultly fusible metal by spraying, coating the sprayed surface and the metallic surface with a fusible metal, heating sufficiently to melt the fusible metal but not the sprayed metal and applying pressure. An insulating sleeve 6, which may comprise a number of layers of paper impregnated with a phenolic condensation product hardened at 150‹ C, is secured by such joints to a sleeve 3 united by a soldered joint 5 to the lead sheath 4 of the cable, and to an annular member 15 having a flange 18 bearing against a flange 20 on a screw-threaded sleeve 19 which is soldered to the conductor and on which is clamped the connector 23. The inner surface of the sleeve 3 is irregularly tapered and the survace 11 thereof roughened, the end of the tube 6 being similarly formed but about 0.002 inch larger in diameter. The end of the tube 6 is sprayed with particles of a metal such as copper, which strikes the tube when at a temperature of about 60‹ C. The ends of the tube and sleeve are tinned with fusible alloy at about 200‹ C, the sleeve is heated to 350‹ C, and the two parts united under pressure. The tinning alloy is thus fused between the surfaces, and on cooling the sleeve shrinks on the tube. Insulating fluid may pass through a tube 27, a gasket 21 rendering the end-joint fluid tight.

Title: Improvements in or relating to couplings between a rod or stem and a surrounding coiled spring
IPC: F01L3/10
Filed: 1945-05-02
Abstract: 595,696. Valve spindles. MARTIN. A. H. M. L., and LEWIS, A. L. May 2, 1945, No. 11172. [Class 135] [Also in Groups XXIII and XXVII] The invention relates to couplings between a rod or stem and the end of a spring surrounding and exerting an axial force thereon, and is described with reference to a poppet valve. A valve spring abutment 16 is coupled to the valve stem by a divided. cotter 12 seated in a groove 11 and fitting into a conical cup portion 13 of the abutment, the cotter parts being held together by a spring 32 and the abutment 16 is formed with an enlarged lower cage portion 14 into which the cotter parts can expand for removal of the valve. A light spring 17 rests on a washer 18 and urges the cotter into the cup 13. To remove the valve, the abutment 16 is raised by a valve lifter 19, Fig. 3, a valve guide extension 20 or a sleeve on the valve stem forcing the cotter parts out of the groove 11 into the cage 14. In modifications, the upper end of spring 17 encircles a lip on the cotter parts to hold them together, dispensing with the spring 32, and the lower end rests on a circlip or recess in the part 14. Alternatively, the cotter may be held in place by a member screwed into the part 14. In Fig. 10, the spring 17 forms the cage portion containing the cotter parts when forced out of the groove 11. A sharp-edged tool 27, Fig. 12, may be used for expanding the cotter, or it may be fitted with lips for engagement by the spring arms 29 of an extractor, Fig. 14, a central screwed stem 30 pushing in the end of the valve stem for withdrawing the cotter after the valve lifter relieves the pressure thereon.
