Inventor: STANLEY ROBERT KENNETH
IPC: D02G1/12
Filed: 1968-07-16
Abstract: 1,186,294. Crimping fibres. TECHNISERVICE CORP. 16 July, 1968, No. 33912/68. Heading D1F. In a process for compression or stuffer-box crimping a textile strand e.g. of thermoplastic continuous filaments and/or staple fibres, hot vapour e.g. steam which may be at the plasticisation temperature of the material of the fibres &c., is directed e.g. by one or more pairs of narrowly and/or widely angled jets, and applied onto the strand from diametrically opposite sides adjacent to and in advance of the entrance to a temporarily confining region through which passage of strand is impeded e.g. by loaded flap, fixed obstruction or frictional resistance, sufficiently to impart the crimped configuration. The force of vapour from jets may be alternately increased and decreased to traverse the strand across the nip of feed rollers and the juxtaposed entrance and thereby ensure uniform distribution of the strand. An auxiliary e.g. radiant, heater may precede the jets.

Title: Improvements in or relating to mechanical assemblies, such as a worm and nut and their manufacture
IPC: F16H25/24
Filed: 1960-10-05
Abstract: In an assembly having a first member moving relatively to a second member, a space exists between the members; and the second member is coated with a synthetic plastics material so as to fill up said space and also to reduce the friction between the engaging surfaces.  In a method of applying the synthetic plastics material to the required surface, the members are axially and radially aligned so that the space therebetween is uniform and the synthetic plastics material is injected into said space; one surface having been pretreated so that the synthetic plastics material cannot adhere thereto.  The synthetic plastics material may be epoxy resin, graphite and catalyst.  A suitable material for protecting the mating surface with the greater dimensional accuracy, is polytetrafluoroethylene or a silicone which may be applied by a spraying or dipping operation, followed by heating to cure the coating.

Title: Improvements in automatic weight announcing weighing machines
IPC: G01G23/18
Filed: 1933-12-05
Abstract: 431,514. Weighing-apparatus. VALLE, J., 30, Clyde Road, Addiscombe, Croydon. Dec. 5, 1933, No. 34177. [Class 143] [See also Group XXXVIII] A combined weighing-machine and gramophone comprises a device for lowering or directing a guide arm carried by the gramophone tone arm or the needle or a projection on the sound-box or tone arm into one of a number of spaces much wider than a record groove in a co-operating guide block in such a way that the needle is automatically directed into the exact groove in which the weight corresponding to the weight on the platform is recorded. The invention as described relates to a coin-freed pendulum weighing machine indicating visually and announcing vocally the weight in stones and pounds and comprising two sound boxes 27, 30 Fig. 1 carrying guide arms 43, 44 respectively which are adapted to be engaged in V-shaped spaces in a guide block 45 so as to direct the needles 28, 31 into one of the sound grooves A, B, C (stones) and 1-13 (pounds) respectively, Fig. 3, in the record 46. A weight on the weighing- platform draws down the lever 14, Fig. 1, to cause the balancing arm 15 and cam 35 to move to the dotted position 15<1>, 351 whilst the insertion of a coin energizes the electric motor 16 to turn shaft 17 through reduction gears 18, 19 through one revolution only at each operation of the machine. Rotation of eccentric 20 carried by shaft 17 moves the rod 24 to which it is connected by rod 21, bellcrank lever 22 and link 23 so as to allow the carriage 25 carrying sound-box 27 to move to the dotted position 25<1> under the action of a weight 26. A second carriage 29 carrying sound box 30 is also released in the same manner and moves to position 29<1> under the action of another weight, (not shown), pushing lever 32 pivoted at 33 to position 32<1>. Lever 32 thus forces plunger 34 down on to cam 35 against the action of springs 56, 57, the cam 35 being in position 35<1> corresponding to the weight on the platform, the carriage 29 thus being located in a position corresponding to the weight. Carriage 25 is also located through similar levers, (not shown), and through another cam rigidly fixed to cam 35. The shaft 17 also drives a shaft 36 having a gear 39 for driving the turntable spindle 48 and a cam 40 which acts through lever 41 and shaft 42 to lower the guide arms 43, 44 into the predetermined spaces in the guide block 45. The parts are so arranged that the rod 24 moves clear of the carriage 25 and does not re-engage therewith until the sound-boxes have been lowered on to and raised from the record by the shaft 42. The record 46 has the same weight recorded in a number of consecutive grooves so that when one of these becomes worn, the needle can be engaged in an adjacent groove in which the same weight is recorded, the guide arms being each provided with a screw 58, Fig. 3, for adjusting the relative positions of the guide arms and needles.

Patent GB-645422-A (GB)
Title: Improved process for the production of viscose rayon threads
IPC: D01F2/06
Filed: 1947-12-29
Abstract: Viscose rayon threads comprising a number of individual filaments which are ribbon-like and also bent over in reniform in cross-section are obtained by guiding the threads in the spinning bath so that at least some of the individual filaments float on the surface of the bath as they are being solidified.  The coagulating bath may be a solution of sulphuric acid, sodium sulphate, and magnesium sulphate. The threads produced are soft to the touch and have a fullness rendering them suitable for use in making hosiery.  To enable the filaments to float on the surface of the bath, the spinning nozzles are arranged immediately below the surface and the threads are guided for a substantial distance, e.g. 50 cm., along the length of the bath.  The number of filaments floating on the surface of the bath may be increased by increasing the density of the bath.  Viscoses of low alkali content may be used.

Title: Immiscible liquids measurement
IPC: G01N33/18
Filed: 1975-08-21
Abstract: 1507747 Photo-electric determination of oil in water STANDARD TELEPHONES & CABLES Ltd 21 Aug 1975 34778/75 Heading G1A To measure the amount of a first liquid dispersed in a lower refractive index liquid with which it is not miscible, an unclad optical fibre is immersed in the liquids and its optical attentuation is measured; the fibre has a refractive index greater than that of the second liquid, but not more than 0À1 greater than the first, and is periodically cleaned to remove any build up of the first liquid on the fibre. The measurement may be used to determine the amount of oil dispersed in water. As seen in Fig. 2, an oil droplet 20 on the fibre 21 allows light propagating along the fibre to escape into the dispersion 22. by detecting the light passing to a photo-detector at the end of the fibre, the amount of oil can be found. A suitable light source is a Ga As laser, a He-Ne laser, or a quartz-halogen lamp; for oil in water measurements the fibre may be of silica. Fibres of differing refractive indices may be used to distinguish between oils. To prevent oil buld up on the fibre during continuous monitoring of liquids in a duct, the flow may be switched periodically to a second duct and fibre while the first one is flushed clean. Ultrasonic cleaning may also be used. To eliminate the effects of particles in the flow, the measurement may be compared with results produced by a flow from which the oil has been removed.

IPC: A23J3/34
Filed: 1960-10-11
Abstract: A nutrient is prepared by hydrolysing pasteurized whey at pH 2.5-7 by means of a proteolytic enzyme operating at this pH.  The whey may be concentrated or enriched with protein before or after pasteurizing. The enzyme is preferably one which hydrolyses proteins to polypeptides rather than amino acids; pancreatic enzyme, trypsin, pepsin, ficin, papain and proteinase derived from Aspergillus oryzae are referred to.  The hydrolysis temperature is 48-55 DEG  C.  The time of hydrolysis is preferably such that not more than 40% of the total nitrogen is precipitable by trichloracetic acid.  The hydrolysate may be concentrated and cooled to precipitate some of the lactose.  The hydrolysed whey may be made into a drink by adding a sweetening and flavouring agent, e.g. sucrose or glucose and fruit juice or fruit ester, and, if desired, carbonating, the pH of such a drink being preferably adjusted to 3.3-3.6 by citric, tartaric, lactic, malic or phosphoric acid.  In making dietary preparations, vitamins, mineral salts, lysine hydrochloride, proteins such as soya flour and carbohydrates exemplified by starch and sugar may be added to the hydrolysed whey, or it may be thickened by methyl cellulose, carboxymethylcellulose, an alginic acid derivative, pectin or gelatine.
