IPC: C07K1/12
Filed: 1928-11-28
Abstract: 325,831. Johnson, J. Y., (I. C. Farbenindustrie Akt.-Ges.). Nov. 28, 1928. Enzymes; synthetic rubber.-Enzymes are obtained when rubber latex or mill, which contain enzymes firmly bound to albuminous substances are treated in a slightly acid solution with enzymes or substances containing enzymes, which chemically alter the albumen by degradation but which do not destroy the enzymes present. The products may be purified by removing the electrolytes by electrodialysis and if desired by isolating the enzyme by selective adsorption. The proteases, including papayotin, and moreover bromelin, animal or vegetable pepsin, tryptases either alone or in mixture with erepsin or activated by kinases such as enterokinase from the small intestine and similar ferments mav be employed. The enzymes recovered are employed for the polymerization of butadiene and its homologues. In examples, a solution of succus caricae papayae is added to dialysed latex made acid with alkali metal citrate or primary alkali metal phosphate. The rubber is coagulated and separated and the filtrate purified. If desired the enzymes which comprise catalase can be isolated by selective adsorption. The enzymes are suitable for polymerization, organic oxidation, reduction, degradation and splitting processes. An aqueous solution of papaine prepared from papaya fruits is added to acidulated milk, the solution obtained is freed from electrolytes and may be used directly nr concentrated by evaporation.

IPC: G11B15/32
Filed: 1959-10-19
Abstract: 911,129. Feeding magnetic tapes. VECTRON ELECTRO-PHYSICS Ltd. Oct. 17, 1960 [Oct. 19, 1959], No. 35385/59. Class 40 (2). A capstan 20, mounted on outwardly spring- biased arms 23, 24 feeds a tape past a head 21, from a single-flanged reel 16 on to the inward face 31 of an annular member 18, which additionally serves as a pinch-roller. The leading end of the tape is anchored by a pin- and-loop arrangement 27, the accumulating tape acting as a pinch-roller while the capstan and head move towards the centre of the spool 25. To rewind, the arm 23 is lifted clear of the space 17 and the spool 16 driven; since the point of contact of the tape with the convolutions stored on the member 18 moves anticlockwise as the tape is re-spooled clockwise on to a smaller diameter, rewinding requires threequarters to one-third the number of revolutions of the spool 16 as compared with normal spoolto-spool rewinding. In a further embodiment, the member 18 is driven simultaneously with the spool 16, which further halves the rewinding time. In a further embodiment (Fig. 5, not shown) the spool 16 and the member 18 are eccentric to one another, the space 17 being of lune-form to provide wider accommodation for the head and capstan.

Thermostats.-In a temperature regulator consisting of a rhomboid-shaped pipe system through which passes a heating medium to be regulated, the upper and lower corners are, formed by pipe sockets 2, 3, the lower of which may be connected to a hot water boiler and the upper to the riser pipe. The other two corners are connected by a pressure bond 4 consisting of two rods or pipes connected by a member 5 having a central opening. The outer ends of the pipes 4 are mounted in end pieces 7 forming seats for the corners of the pipe system, and the length of the bend is so adjusted that it is not released at any temperature which may occur. A plate 21 is rotatably mounted in the socket 3 and carries two conical studs 8 forming fulcra for seats 9 carried by a part 10 rigidly connected to the controlling lever 11. Another seat 14 is provided in the lower end of a freely mounted rod 13 extending between the upper and lower corners of the rhomboid. Temperature change thus permits the lever 11 to pivot about the axis 8, 8 as the rod 13 moves vertically on expansion of the pipe system. The lever 11 is also capable of swinging laterally since the members 10, 21 are capable of rotation together about the axis of the rod 13. The seats 9, 14, 16 are all directed downwards to avoid accumulation of dust about the pivots.

Nov. 27, 1929, No. 36356. Convention date, Feb. 5. [Class 105.] Hand - levers and hand gearing ; wire and like compensators ; wires for operating signalling apparatus.- Signal hand-levers are connected to the signal wire by mechanism so arranged that the manual effort required to be exerted on the lever is substantially constant throughout the whole stroke of the lever. The leverage ratio is at first large to take up the slack of the wire rapidly and thereafter diminishes during the actual pulling-off of the signal. The arrangement may comprise a bell crank 3, 4, Fig. 2, in which the effective arm X for the hand-lever connection 9 increases during the stroke while the effective arm Y of the signal wire 5 is at first constant and then decreases. In Fig. 9 is shown an arrangement in which a roller 36, to which the signal wire is connected, is constrained by a link 37 to move inwards on the tail 33 of the handlever 34. Fig. 10 shows an arrangement similar to that of Fig. 2 with the addition of a device for compensating any expansion or contraction of the wire. The signal wire passes over pulleys 43, 46 on a triangular member 39 and is maintained under tension by a weight 47. On actuation of the hand-lever the connection 48 causes a gripper member 45 to engage the wire and thereafter the triangular member 39 moves about its pivot 40 acting in the manner of the bell crank construction. The triangular member 39 normally rests against a stop 52. Other arrangements comprise cam slots in sliding or rotatable members, a spiral cam actuated by a rack connected to the hand-lever, and a bell crank similar to that shown in Fig. 2 arranged in the run of the wire.
