Title: Improved process for the production of crystalline insulin
Inventor: PETERSEN KARL
IPC: C07K14/62
Filed: 1953-02-10
Abstract: A process for the production of crystalline insulin in which the insulin is brought to crystallize from a medium containing cations prerequisite for crystallization by changing the pH value of the medium to pH 5.0 to pH 7.0, is characterised in that cupric ions, manganous ions or ferrous ions, or mixtures of these ions, are used as cations prerequisite for crystallization.  Based on the weight of the medium, the quantity of metal ions are (a) copper, at least 0.01, and preferably 0.05 to 0.1, per cent. by weight; (b) manganese, at least 0.1, and preferably 0.2 to 0.5, per cent. by weight; and (c) iron, at least 0.05, and preferably 0.1 to 0.2, per cent. by weight. The metals may be present as (a) salts, e.g. sulphate, nitrate, chloride, acetate or citrate; (b) hydroxides, provided an acid crystallization medium is employed; or (c) complex salts.  It is preferred to use an insulin concentration of 0.1 to 1.0 per cent. and a purity of 22 to 23 international units per milligram.  The insulin solution may be obtained by dissolving amorphous insulin in aqueous mineral acid, e.g. hydrochloric, sulphuric or phosphoric acids or may be one obtained during the isolation of insulin from pancreas. Naturally present zinc may be removed by dialysis.  Other additions are (a) buffers, e.g. acetate, borate, diethyl barbiturate, phosphate and citrate (preferred) buffers, or mixtures thereof; (b) organic solvents which promote crystallization, e.g. propyl alcohol, butyl alcohol, amyl alcohol and acetone, which is preferred.

Title: Improvements in explosive armour piercing projectiles
IPC: F42C15/26
Filed: 1953-02-12
Abstract: 725,821. Projectile fuzes. BREVETS AEROMECHANIQUES SOC. ANON. Feb. 12, 1953 [Feb. 27, 1952], No. 4017/53. Class 9(1). A shell 1 containing a charge 2, which may be incendiary, is provided with an armour-piercing nose 3 of hard metal to which is attached an ignition device 4. The device 4 comprises a percussion fuze having means for locking the firing pin 17 which is released only by penetration of the shell into a target having some predetermined minimum resistance. Furthermore after release of the locking means, due to inertia holding means prevent movement of the firing pin until the shell has passed through the target. The ignition device is provided with a sleeve 6 held against forward movement by an elastic ring 8 bearing against a shoulder 9 and against rearward movement by two cylindrical masses 12 having frusto-conical ends bearing on a frusto-conical surface 19 of a plug 20. A slidably mounted inner sleeve 13 houses in a groove 14 a ring 15 divided into section, each section forming a centrifugal mass. A spring 16 holds the inner sleeve in engagement with a flange 18 on the firing pin 17, the pin being held by the masses 12, as on the left-hand side of Fig. 2. After firing the shell, the centrifugal force due to rotation causes the masses 15 to move outwardly and bear against the inner surface of sleeve 6, which has a frusto-conical bearing surface corresponding to similar surfaces of the masses 15. The ring 8 moves outwardly into the recess 10, thus allowing the masses 12 to move upwardly against the action of spring 16 and outwardly in the openings 11 to take up the position shown on the right hand side of Fig. 2. The firing pin is then unlocked and the outer sleeve locked in the forward position. On impact the centrifugal force on the masses 15 is reduced and inertia causes a forward movement of the sleeve 6 relative to the inner sleeve 13, so that the masses 15 are thrust inwards and the inner sleeve 13 released. The stressed spring 16 then forces the firing pin 17 into contact with a primer 24 to initiate the detonator. Specification 624,811 is referred to.

Title: Improvements in or relating to switching apparatus for telephone systems
IPC: H01H67/06
Filed: 1923-02-10
Abstract: 213,072. Western Electric Co., Ltd., (Western Electric Co., Inc.). Feb. 10, 1923. Selectors. - Switching-apparatus for use as a non-numerical or numerical switch or in a register - controller, comprises a number of sets of movable terminals each associated with, but normally out of contact with, a common set of bare-wire conductors constituting fixed terminals, means being provided for selecting a particular set of movable terminals which are then moved into contact with the common terminals. In the construction shown, the barewire conductors 72 - - 75 are woven in and out of insulating strips 22, arranged in a semi-circle and held at their extremities in notches in top and bottom frame plates 1,2 2 as shown in Fig. 1. Each set of movable terminals comprises wires 62 - - 65 fixed at one end in insulating blocks 3, and extending at their other ends, through slots in movable bars 16, to positions adjacent to the conductors 72 - - 75. The blocks 3 are fitted in notches in the outer edges of the frames 1, 2 and are held by wire straps 8. The movable bars 16 are held in position, so as to be free to slide vertically, by means of semi-circular bands 11, 81, whilst each bar is normally supported in its uppermost position so as to hold the conductors 62 - - 65 out of engagement with the conductors 72 - - 75 by means of a spring 78. In order to select a particular set of movable terminals, the shaft 42 is rotatable by means of a ratchet-wheel 47 and a co-operating pawl 57 associated with the armature of a magnet 51. If the switch is to be operated numerically, the required number of impulses are sent through the magnet 51 and the shaft 42 is stepped round until one of its arms 43 is above a particular one of the movable bars 16. Circuit changes then take place which cause a solenoid 48 surrounding the lower ends of the shaft to draw down the shaft against the action of a spring 49, the arm 43 thus pressing down the selected bar 16 so that the conductors 62 - - 65 are moved into contact with the adjacent portions of the conductors 72 - - 75, the obliqueness of the slots in the bars 15 causing a rubbing action to ensure good contact. At the end of a connection, the solenoid 48 is de-energized and the necessary number of impulses are sent through magnet 51 to restore the shaft 42 to normal. If the apparatus is employed as a hunting-switch, the self-interrupter contacts 54, 55 of magnet 51 are brought into circuit, and an extra contact 61, engaged bv projections 46 on a conducting plate 44 fixed to the shaft, acts as a test terminal, the plate 44 being fed with current through a wiper 41. In modifications, the selecting device may have a rectilinear movement, or may have two or more distinct movements. Specification 29615/13 is referred to.
