Title: Improvements in or relating to purifying crystalline insulin
IPC: A61K38/00
Filed: 1961-10-04
Abstract: Crystalline insulin contaminated with amorphous and microcrystalline impurities are purified by washing the impure crystallisate with an aqueous liquid the pH of which is held at from 3.8 to 4.3 (preferably from 4 to 4.3) with a weak acid or buffer mixture.  The process may be applied to any impure insulin crystallisate obtained by standard methods but it is preferred to use crystallisates having an activity of at least 22 I.U. per mgm. Suitable wash liquids are dilute acetic acid, ammonium acetate/citrate, ammonium phosphate and sodium phosphate buffer solutions.

Title: Improvements in and relating to the zone-melting of rod-shaped materials in vacuo by electron bombardment
IPC: H01J37/305
Filed: 1968-07-26
Abstract: 1,179,805. Zone-melting. BALZERS PATENT-UND BETEILIGUNGS A.G. 26 July, 1968 [14 Aug., 1967], No. 35773/68. Heading B1S. In the zone-melting of a rod in a vacuum using an electron beam as heating means, the beam is deflected by means of a guiding magnetic field parallel to the rod so that the electrons encircle the rod and impinge it all round the molten zone. As shown, an electron beam 4 passes through a magnetic focusing lens 5, a deflector device 10, and a diaphragm 12, and then passes between cooled and screened electromagnets 8, thereby being deflected into a path around the rod. The strength of the field may decrease inwardly. The rod may be rotated during the treatment. The radius of curvature of the electron path may be varied by varying (a) the strength of the guiding magnetic field, (b) the electron accelerating voltage, (c) the exciter current of the electromagnetic focusing lens, or (d) the direction of entry of the electron beam into the guiding magnetic field by means of the deflector device 10. A further deflector device at right angles to device 10 may vary the width and/or temperature of the molten zone.

Title: Improvements in or relating to apparatus for removing skin particles from a donor area and applying the particles to a recipient area
IPC: A61B17/322
Filed: 1958-11-11
Abstract: 844,190. Skin removing. PITCO PRODUCTS, Inc. Nov. 11, 1958 [Nov. 25, 1957], No. 36216/58. Class 81(2). Apparatus for carrying out skin grafting operations comprises a rotary cutting head for removing skin particles from a donor area, a container to receive the particles and spraying means for applying the particles to the recipient area. The device is provided with a pistol grip handle 12 and a flexible drive 88, powered by an electric motor, drives a cutting head 74 having a radial serrated blade 92 which is held against the inner face of a conical head 66 by a spring 112, so that when the head is pressed against the patient's body, skin protruding through a slot 70 is cut off in small particles by the cutting blade. During the cutting operation suction is applied through a tube 134, which is raised off its seating 138 by a trigger lever 14, and is consequently communicated through a chamber 192, a port 200 in a turn cock 40, duct 188 and tube 190 to a container 20. Severed particles are thereby drawn into the container through a tube 126, which is connected through ducts, not shown, to a circular channel 118 and a port in the head 74 leading from the'cutting edge. At one point in each rotation of the cutting head a further port, adjacent the cutting blade, is aligned and in communication with a duct leading from a vessel supplying flushing solution, so that this solution is sucked into the head and over the cutting blade to wash off skin particles, which are then drawn up into the container 20. When the desired quantity of skin particles has been collected, the cock 40 is turned through 90 degrees, in which position port 198 connects chamber 192 with duct 186 and port 196 completes a straight-through passage 174 from the container 20 to the centre of the spraying head 18. At the same time air under pressure is supplied through the tube 134, under control of the trigger operated valve 138, and this issues from the annular chamber 182 around the nozzle 170, so creating a suction which draws the skin particles from the container 20 and projects them on to the recipient area. At the same time a suction is created in an intermediate annular chamber 176, communicating with a duct 180, through which coagulating fluid may, if desired, be drawn from a container 28. The power unit for use with the appliance preferably comprises an electric motor, the shaft of which drives the flexible drive cable 88 and also carries an eccentric vane pump. The motor is reversible and the pump, which is connected to the tube 134, is thus able to produce pressure or vacuum according to its direction of rotation.

In Fig. 2 drive is initially via gears 124B, 140, 144, 114, gear 140 being latched to the shaft 134 of gear 144 by pawl 156. To change the drive a spring ring 168 is removed from shaft 134 which is then pushed into the housing; pawl 156 disengages gear 140 and engages gear 142 snapping over the edge of washer 148 and thus preventing withdrawal of shaft 134; this arrangement converts from quarts to litres. In Fig. 4 the initial drive is direct via a dog clutch 210, 212; to convert, a slide 230 is pushed into the housing, after removing a locking pin 238, such that cam surfaces 240 drive the slidable gear 200 upwards to disengage the clutch and introduce a gear ratio which converts from gallons to litres.

Abstract: 1,101,706. Grinding. ETABLISSEMENTS BIEBUYCK. 15 Aug., 1966 [4 Oct., 1965], No. 36392/66. Heading B3D. A machine for smoothing or dressing the top rim of tumblers comprises a head 9 arranged to grip the tumbler by its base, a device to rotate the head about the axis of the tumbler, a grinding or polishing tool 12, 13 supported for movement towards and away from the gripping head and formed by two flexible grinding or polishing elements which are positioned symmetrically one on each side of the direction of application of a tumbler against them and which, when not engaged by a tumbler, are situated in a common plane at right angles to the direction and, during a rim smoothing action, bend or flex slightly when the rim is engaged therewith, end means for moving the head and a tumbler gripped thereby towards and away from the grinding tool. As described, the machine consists of a pair of uprights 5, 6 having a fixed upper member, which carries a plurality of heads 9 for gripping the feed 3 of tumblers 1, and a vertically displaceable bottom member 8 which carries a plurality of grinding tools 12, 13. The heads 9 are vertically displaceable by means of pneumatic piston and cylinder devices under the control of electromagnetic valves. Each head has a bearing face having a number of claws 11 which are movable by rack-and-pinion mechanisms controlled by a cam, the cams being mounted on a common shaft and arranged upon rotation of the shaft to operate successively. The heads are rotated by conventional means and are then moved to present the rims of the tumblers to the grinding tools. Each tool consists of a pair of conical discs 14, 15 secured to rotatable spindles 16, 17, each disc supporting a flexible metal sheet 12, 13 having a diamond covering or facing on its marginal upper face. Liquid, such as water, is supplied by. jets 18 . . . 21 to the inner and outer surface of the rims. The discs 12, 13 are rotated in the same direction and opposite to that of the tumbler and during grinding or polishing flex slightly. The height of the lower member 8 carrying the grinding tools is automatically adjustable to the height of a tumbler 1 by the use of a specimen tumbler 22 which is placed upon a support 23 and, when the member 8 is raised to the correct height, engages a sleeve of adjustable length to operate a switch. In an alternative embodiment, the grinding or polishing discs are replaced by endless abrasion belts, the belts of each pair moving in opposite directions and are disposed with their active portions above sloping planes, whereby they can flex when engaged by the rim of the tumbler.
