Title: Improvements in or relating to viscous solutions of vegetable globulins
IPC: D01F4/00
Filed: 1941-10-22
Abstract: 553,539. Globulin solutions ; artificial filaments. THOMSON, R. H. K., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 22, 1941, No. 13560. [Classes 2 (ii) and 2 (iii)] The surface gelation of a viscous solution of a vegetable globulin in a dilute aqueous solution of a strong base is prevented by storing the solution in an atmosphere of ammonia. The surface of the viscous globulin solution is preferably freed from air bubbles before the atmosphere over the solution is replaced. The introduction of ammonia is not continued since excess of ammonia causes diminished viscosity and gelation below the surface. In an example, peanut protein is dissolved in aqueous caustic soda and is placed on a cylindrical vessel provided at the top with a pipe leading to an ammonia cylinder and at the bottom with an outlet leading to a filter and spinnerette. Ammonia is introduced into the air space so as to give an excess pressure of 7 pounds per square inch, and the vessel left sealed for 16 hours. All the solution can be used for the production of filaments by extrusion into a coagulation bath without waste. The production of films, adhesives and plastics is mentioned.

Title: Improvements in and relating to measuring or gauging apparatus
Inventor: BARNES DOUGLAS CHARLES
IPC: G01B3/24
Filed: 1953-05-14
Abstract: 759,150. Gauge - - testing apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 16, 1954 [May 14, 1953], No. 13578/53. Class 106 (2). Apparatus for testing, e.g. dial gauges comprises means which apply a continuously variable displacement to the driving link of the gauge under test and which produces a relative movement between a reference mark and the gauge such that the mark indicates the position the pointer of the gauge should occupy if the gauge is accurate, throughout the displacement of the driving link. As shown, the gauge 21, Fig. 1, to be tested is mounted on a supporting plate 18 which can be rotated on a shaft 14 relative to the base 11 of the apparatus. The shaft 14 is coaxial with a stationary helical gear 13 which engages with a helical pinion 33 secured on or integral with a lead screw 29 pivoted at its ends in lugs 27, 28, Fig. 2, formed at the bifurcated end of the supporting plate 18. With the screw meshes a nut formed in two portions 34, 35 on opposite sides of the pinion 33 to permit a considerable traverse along the screw, the nut being formed in or secured to a saddle 36 whose rotation relative to the screw is checked by a screw 37 carried in a cross-bar 39 joining the lugs 27, 28. Against a flat surface 42 of the saddle 36 are pressed two piles of slip gauges 43, 44 upon which are seated two balls 45, 46 carried at an accurately known distance apart on the underside of a bar 47. A block 48 secured to the plate 18 carries a plunger 49 having a round end riding on the bar and the other end actuating the plunger 22, i.e. driving link of the dial gauge under test. During a test the dial gauge supporting plate is rotated by means of gearing 55, 56 and its plunger is continuously displaced as it moves relatively to the sine-bar 47 which is traversed by the engagement of the nut 34, 35 with the leadscrew. The pitch of the screw, the ratio of the gears 13, 33 and the slope of the sine-bar are so chosen that during the rotation of the dial guage its indicator, if the gauge is accurate, should remain stationary with respect to a datum mark 26 secured to the apparatus frame. As shown, the mark 26 is in double form which straddles the correct position so as to show whether the instrument under test is within a tolerance corresponding to the spread of the double mark. In another embodiment the gauge to be tested is mounted on a base board with a similar instrument of high accuracy and by means of a lead-screw and a cross-bar the same displacement is given to the plungers of both gauges. The gauges are spaced at a suitable distance apart and are observed as a stereoscopic pair so that any deviation of the gauge under test may be visually detected.

Filed: 1974-03-27
Abstract: 1406595 Seawater battery ESB Inc 27 March 1974 [18 May 1973] 13591/74 Heading H1B The entry 42 for seawater in the cover 12 of a battery container 10 is normally sealed by a valve closure member 20 having a sealing ring 24. The member 20 is retained from movement into the container 10 by a flat bar 15 of ductile material but which also has some resiliency, a preferred material being aluminium. The bar 15 has a length greater than the diameter of the entry 42 and has a disc-shaped backing piece 18 on its upper surface, the components 15, 10, 18 being held together by a screw 17. Outward movement of the closure member 20 is prevented by a stirrup 16. When the battery is dropped into seawater and reaches a certain depth the pressure on the outside causes the ends 40 of the bar 15 to bend and pass through the entry 42 whereby seawater enters the container and activates the battery plates 30, Fig. 4. The ends 40 deflect somewhat after leaving the entry 42 whereby the closure member 20 cannot return to re-seal the entry. Preferred electrode plate couples are: lead chloride-magnesium; silver choloride-magnesium; and cuprous chloride-magnesium. Alternatively, the anodes may comprise zinc or aluminium.

Abstract: 1,183,702. X-ray analysing apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 29 March, 1967 [30 March, 1966], No. 14127/66. Heading H5R. An X-ray analysis apparatus includes a rotary holder carrying a plurality of crystals. each having suitable reflecting properties over a different X-ray band, a Geneva mechanism being mechanically coupled to said holder so that a selected one of said crystals may be indexed into a position where it is in the path of an X-ray beam emitted by a specimen bombarded with electrons, the apparatus also including means whereby the angle of reflection of the X-rays from the selected crystal is measured. As shown in Fig. 3, the motor 23 drives the crystal holder 32 through right angle gear train 24, 25, belt and pulley arrangement 26, and pin 28 on wheel 27 interacting with slots cut in the underside 30 of holder 32, the required precision of motion being ensured by the interaction of cam face 29 and underside 30 which is seen most clearly in Fig. 2 (not shown). Fig. 4 illustrates a crystal support 32 having mounts 34 for four crystals, e.g. lithium fluoride, mica, potassium acid phthalide, and lead or barium stearate, on dowel pins 35, the crystals being retained in position by springs 39 fastened to a projection from mount 34 which projection extends downwardly into slot 38. Fine adjustment of the individual crystals is accomplished by turning the slotted shaft 40 which via cam face 42 pushes mount 34 radially with respect to the central shaft and by turning the slotted shaft shown as operating in slot 38 which causes an angular rotation of the crystal about said downward projection. The X-ray apparatus may include a specimen chamber having a window which may at will be covered to cut off all X-rays from the specimen, or may be covered with a cover member of a material such as to cut off all X-rays of the longer wavelengths. This covering and uncovering of the window may be accomplished using a slide type mechanism which may be piston operated (Fig. 7, not shown). The reflected X-ray beam may be collimated to impinge on a suitable dector using the collimating system disclosed in Specification 1,136,255 (Figs. 8 and 9, not shown).
