Title: Improvements in or relating to the production of photographic emulsions
Inventor: WOOD HENRY WALTER
IPC: G03C1/047
Filed: 1956-08-29
Abstract: Polypeptides are prepared by the polymerization of pure N-carboxy-a -amino anhydrides or mixtures of such anhydrides preferably by heating the anhydrides in dioxan with sodium methylate as catalyst, or by heating above their melting points. The polypeptides may contain residues of glutamic acid together with one or more residues of lysine, sarcosine, phenylalanine, cystine, proline or glycine. Those containing lysine may be guanidated by treatment with o-methyl-isourea.  In the case of amino acids such as glutamic acid and lysine, the active groups are protected during polymerization by using, as starting material g -methyl glutamate anhydride or e -carbobenzyloxy-lysine anhydride.  After polymerization, the protective groups are removed by adding the polymer to hydrobromic acid in glacial acetic acid in the cold.ALSO:Polypeptides are prepared by the polymerization of pure N-carboxy-a -amino anhydrides or mixtures of such anhydrides.

After polymerization, the protective groups are removed by adding the polymer to hydrobromic acid in glacial acetic acid in the cold. The N-carboxy-a -amino anhydrides are formed from the a -amino acids by treatment with benzyl chloroformate to give N-carbobenzyloxy-a -amino acids (in the case of lysine the e -NH2 group also is attacked at the same time as the a -NH2), the acid group is converted to its acid chloride and the ring closes to form the anhydride with loss of benzyl chloride.  The pure anhydrides are obtained by recrystallizing several times. Specification 721,067 is referred to.

Abstract: 753,425. Hydraulic brakes. GOODYEAR TIRE & RUBBER CO. Sept. 13, 1954 [April 13, 1954], No. 26415/54. Class 103 (1). The torque resistance of an hydraulicallyoperated brake, which, as shown, is a twin disc brake comprising discs 1 and 2 and actuator cylinders 5 and 6, is governed by the operation of a valve spool 52 which cuts off and connects to a reservoir 17, the fluid supply line 22 from the pump 16 to the cylinders 5 and 6. The valve spool 52 is operated by the pistons 60 and 69, the pressures above which are those existing in the chambers 15 of servo-valve devices 12, these pressures being made to correspond with the magnitude of the torque on the discs in the following manner. The collar and piston members 9 secured to the brake support arm 3 are guided on inclined splines 1 whereby angular movement of arm 3 caused by the torque exerted on pads 7 results in axial movement of the member 9 which through plunger 13 and valve spool 30 having a recess 40 connects a pressure supply line 24 either to the reservoir through line 35 or to the space 15 through line 39. The limiting value of the torque will depend upon the setting of an adjusting screw 73 compressing a spring 75 below the valve spool 52. A control arrangement for a single disc brake is also described.

Title: Improvements relating to thermal protection of single phase a.c. motors
IPC: H02H7/085
Filed: 1955-09-16
Abstract: 771,873. Control of A.C. motors. GENERAL ELECTRIC CO. Sept. 16, 1955 [Sept. 16, 1954], No. 26604/55. Class 38(3) A split-phase motor has a running winding 2, and spring-biased contacts 9 are connected in series with the starting winding 3, these contacts being controlled by armatures 8 and 10. A solenoid winding 11 in the running circuit co-operates with the armature 10, whilst the armature 8 is operated by solenoid winding 7 connected across a portion of the starting winding. The contacts 9 are closed when the motor is started so that both the windings 2, 3, are energized and both the armatures 8, 10, are lifted so that the contacts will remain closed until the motor reaches a predetermined speed. The resultant decrease in the current passing through the solenoid 11 at this speed causes the armatute 10 to drop and break the contacts 9 open the starting circuit. Whilst the motor is rotating a speed-responsive voltage induced in the winding 3 keeps the solenoid winding 7 energized whereby the armature 8 is held up and the contacts 9 remain separated. If the motor stalls or stops due to a drop in the supply voltage. however, the solenoid 7 is de-energized and the armature 8 drops to re-close the contacts 9 so that the starting circuit is reestablished. Repeated failures to start the motor cause large currents to pass through resistance heaters 16, 17 so that after a predetermined period, a bimetal member 15 breaks overload contacts 14.

IPC: B21D3/00
Filed: 1938-09-15
Abstract: 520,230. Making rods and bars. LUKACS. E., and STERN, S. Sept. 15, 1938, No. 26989, [Classes 83 (ii) and 83 (iv)] Altering physical structure; bending and twisting.-To increase the strength of round metal bars by cold working, the bars are rotated in the cold whilst in a bent condition, with or without simultaneous twisting. The bars may be bent first and then rotated, or bent and rotated simultaneously and the rotation may be uniform along the bar or varied to produce twisting. When twisting is produced the bending may be within the elastic limits of the material, but without twisting the bending should be beyond the elastic limit, and the bending may be in one plane or in three dimensions, and may be produced by the weight of the bar or by other means. When bent beyond the elastic limit the bars may be straightened subsequently. The axis of the bar may be given an oscillatory movement during rotation by bending on a curve having points of inflection or by moving the ends periodically. Apparatus for carrying out the method may comprise chucks 7, 7<SP>1</SP>, Fig. 1, rotatable in sleeves 9, 9<SP>1</SP> which are supported by trunnions 25 on pedestals 10, 10<SP>1</SP> adjustable on guides 11. A bar g to be treated is gripped by the chucks, and bent to the required degree by adjusting the sleeves about the trunnions, after which one or both chucks are rotated. Instead of being gripped by chucks, the ends of a bar may be bent round transverse pins on the shanks 8 and held by cotters in the pins. In a modified apparatus the bar is supported in the bent condition on horizontal tables during rotation. For treating continuous lengths of bar stock, the bar is passed through two sets of rollers 19, 20, Fig. 6, arranged at an angle as shown so that the bar g will be bent in passing from one set to the other. The rollers 19 are mounted in a frame 21 carried by bearings 22 and rotated about the axis of the bar so that the rollers will grip the bar and rotate it whilst it is being bent.

Abstract: 224,903. Marilter, C., and Granger, L. Nov. 12, 1923, [Convention date]. No Patent granted (Sealing fee not paid). Alcoholic liquids, distilling. - In separating liquids in a rectifying column, the part of the condensate which is returned as reflux to the column, is mixed with substances, such as salts of mineral or organic acids, which will assist the rectification. In rectifying alcohol, dehydrating agents such as calcium chloride, potassium acetate, &c. are used. Alcohol is first purified by being heated under pressure in a vessel F with alkali to decompose esters. The vapours evolved from the vessel F are condensed in a heat-exchanger H which preheats the alcohol, and the condensed alcohol passes into a vessel I and thence through a purifying column D<1>, D<2>, which separates volatile impurities, into a rectifying column A<1>, A<2>. The alcohol vapour from the top of the column passes to a condenser B. Part of the condensate is discharged through a pipe 1, and the other part is passed by a pipe 2 through a vessel C where. it is mixed with calcium chloride, potassium acetate, &c., and from which it passes to the top of the rectifying column. The vessel C may be provided with means to agitate the contents and may be heated. When the liquid is treated with substances to cause separation into two layers, the layers are separately rectified.
