Title: Improvements in or relating to the production of insulin
IPC: C07K14/625
Filed: 1961-10-04
Abstract: Insulin is obtained from a pancreas extract prepared directly from ground pancreas tissue by extraction with an acidified aqueous extraction liquid containing an organic solvent, with or without intermediate removal in known manner of fatty constituents from said extract, by adding metal ions of zinc, cadmium, iron, nickel, cobalt, copper or manganese, separating off and then dissolving the separated protein fraction in a dilute aqueous acid and then recovering the insulin from the solution so formed.  In one example, cow pancreas is extracted with alcohol containing hydrochloric, acid at pH 2.5, the pH of the liquid is adjusted to 7.5 to 8.5 with ammonia and the liquid is clarified, the pH is then adjusted to 2.5 with hydrochloric acid and an equal quantity of water added to precipitate fatty substances which are separated.  Zinc chloride is added and the pH is adjusted to 6.0 with ammonia to precipitate the insulin and other proteins.  After dissolution in hycrochloric acid of pH 2.5-3.0, insulin is recovered therefrom by known methods.  Preferably the metal ions are added in the form of a salt in which the metal is present in its bivalent form and the pH of the extract is adjusted to 5.0 to 7.5.  Specifications 566,351 and 726,219 are referred to.

Abstract: 368,365. Making meat tender. TRIGGS, W. W., 57, Lincoln's Inn Fields, London. (Pike Manufacturing Co. ; Pike, New Hampshire, U.S.A.) Nov. 29, 1930, No. 36068. [Class 28 (ii).] Apparatus for making meat tender comprises a platen, a manually operated device for forcing cutter blades through the meat into contact with the platen, and a stripper arranged to remove the meat from the blades when the latter are moved upwardly, the blades being adjustably mounted so that they may be aligned with the platen. A base 10 has a recessed part 12 to receive the removable wooden platen 11, the recessed part and platen being of square or other shape so that the platen may be turned through an angle in order that the meat may be cut in two or more directions. Thin knives 16 are removably bolted together with distance pieces between them to form a cutter block which is adjustably secured in a flanged support 14 by screws 37 and other screws provided with lock nuts. The knives 16 are slotted as shown to form narrow spaced blades 17, which are staggered so that the meat cannot be cut into separate pieces. A stripper frame 22 having cross-bars extending between the knives is pivoted on screws 23. It is normally held in raised position by a spring 27, the upward movement being limited by a stop 31 so that in its upper position the stripper forms a guard to prevent the operator's hand from engaging the edges of the blades 17. For adjusting the blades so that all engage the platen, the cutter support 14 is pivoted on an eccentric bushing adjustably mounted on a pin 44. The blades are forced through the meat by a compound lever mechanism comprising a bell-crank lever 55 pivoted on a fixed arm 57 and connected by toggle links 60 to the cutter support 14. The lever 55 has a removable weighted handle 66 which normally holds the support 14 in raised position. To compensate for wear, the effective length of the short arm 58 of the lever 55 may be varied by angularly adjusting the pin 59 connecting it with the links 60, the pin being provided with an enlarged eccentric part fitting within an aperture in the arm 58. The construction is such that the blades 17 cannot come into contact with the metal base if the wooden platen is absent.

Title: Improvements in or relating to Switch-Actuating Means for Multi-Point Process Timers.
Inventor: BURRELL CLAUDE
IPC: H01H43/12
Filed: 1967-08-09
Abstract: 1,192,195. Time switches; mechanical interrupters. A. G. BURRELL CO. Ltd. 6 Nov., 1968, No. 36489/67. Heading H1N. A process timer wherein a plurality of contact sets 5 are operated by respective cams 9 which are axially spaced on, and in frictional driving connection with, a shaft 11, but capable of individual angular adjustment relative thereto, has each contact set actuated by two follower rockers (7, Fig. 1, not shown) cooperating respectively with adjacent cams 9. One rocker 7B of each pair has two laterallyextending pegs 21 while the other rocker (7A, Figure 2, not shown) has a single peg 20 lying between the pegs 21. Spring blades 5 carrying contacts 2 press on respective pegs as shown, the rocker (7A) carrying peg 20 having dropped so that the upper pair of contacts 2 have been opened and the lower contacts 2 closed. When the respective cam 9 has rotated sufficiently for rocker 7B to drop over step 25 the upper contacts 2 close and the lower contacts 2 open. Continued rotation of the cams causes the lift 24 of its respective cam to lift rocker (7A) carrying peg 20 but this engages the upper peg 21 of rocker 7B (through the intermediary of centre spring blade 5) so that both rockers rise, maintaining the upper contacts 2 closed and the lower contacts open. The higher dwell portion 22 of its cam 9 then comes below rocker 7B but the contacts are not affected until the rocker (7A) drops over the step 25 of its associated cam whereupon the contacts are returned to the positions shown. The shaft 11 may be driven continuously or zeroized after a predetermined amount of rotation; and it may be rotated manually by a knob (15, Fig. 1, not shown), for relative setting of the cams by means of a selective camstopping lever as in Specification 1,192,197. Instead of the centre spring blade 5 carrying two contacts, the contact co-operating with that on the lower blade may be carried by a fixed insulating support (not shown).

Abstract: 1,176,065. Apparatus for hot drawing synthetic filaments. TOYO RAYON K.K. 10 Aug., 1967 [13 Aug., 1966; 8 Oct., 1966; 14 Oct., 1966], No. 36849/67. Heading B5B. As shown in Figs. 1 to 3 an apparatus for drawing an undrawn tow of synthetic filaments while the tow in the form of a sheet of parallel filaments is being passed through a bath of hot liquid comprises a pair of feed rolls 1, a pair of draw rolls 2, a bath 4 containing a hot liquid 3, guide rollers 5 and 6 positioned above the level of the liquid 3, and tow immersing arrangement 7 adapted to be raised to the position shown in Fig. 1 or lowered to the position shown in Fig. 2, whereby when the means 7 is in the raised position the tow rises or is raised above the level of the bath liquid and when the means is in the lowered position the tow is immersed in the hot bath liquid and travels therethrough while it is being drawn. The arrangement 7 comprises rods 9 by means of which the guide bars or rollers 8 under which the tow passes are secured to a bracket 10. The bracket 10 is supported by piston-rods 12 of pistons actuated by means of pneumatic cylinders 11 mounted on the support 13. In the event of the travelling of the tow ceasing due to some fault occurring in the treating apparatus, the guide bars or rollers are quickly raised and the tension to which the tow is still subjected causes it to rise out of the hot bath liquid. Alternatively the raising of the guide means 7 may cause the tow to be lifted out of the bath liquid by the members 15 and 16 shown in Figs. 5 and 6, respectively. The bath liquid is preferably heated by circulating it through an external boiler, the bath liquid being withdrawn from the bottom of the bath near the draw roll end of the bath, pumped through the boiler and returned to the bottom of the bath near the feed roll end of the bath. In order to cause the filaments to be drawn within a short length of the path of travel of the tow at the first guide bar 8 the bath may be shallow below the guide bar and the heated bath liquid caused to flow through the bath countercurrent to the direction of travel of the tow, the linear velocity of flow of the bath liquid being at a maximum below the guide bar 8, which in this case is fixed and non-rotatable. A chamber for treating the drawn tow with steam may be provided adjacent to the outlet end of the draw bath so that jets of steam may be directed on to the upper and lower surfaces of the tow immediately after it has emerged from the draw bath and travels through the steam treatment chamber.

Abstract: 1,015,465. Voltage stabilisers. STANDARD TELEPHONES & CABLES Ltd. Sept. 28,1962 [Oct. 4, 1961], No. 36891/62. Heading G3X. [Also in Division H3] The HT supply to a blocking oscillator frame deflection generator V1 of the cathode ray tube of an A.C. mains operated television receiver is stabilized against fluctuations due to fluctuations in the mains voltage by connecting the junction of the decoupling resistor R7 and capacitor C8 in the HT supply via a voltage dependent resistor R11 to an alternating voltage which varies in accordance with the mains voltage fluctuations; such voltage may be derived directly from the mains voltage or from the line output transformer. The voltage dependent resistor R11 may be connected in series or in parallel with an adjusting resistor R12 and the HT may be a boosted supply derived from the line output transformer or it may be taken from the normal receiver HT line. The resistance of resistor R11 decreases with an increase in applied voltage so that if the mains voltage increases thereby causing an increase in the HT at terminal 9, the resistance of R11 decreases and decreases the proportion of the HT across the capacitor C8.
