Title: Therapeutic compositions containing a protease
IPC: A61K9/20
Filed: 1955-10-17
Abstract: A dry stable therapeutic protease composition in final dosage unit form suitable for buccal administration is produced by incorporating with 0.5 to 15 mg. of protease, a pharmaceutically acceptable solid carrier therefor.  The protease may be trypsin, papain, pepsin, bromelin or chymetrypsin.  A pharmaceutically acceptable carrier is defined as being a water-soluble stabilizing and solubilizing agent, a dried animal substance, an encipient or a mixture thereof. Water-soluble stabilizing and solubilizing agents are solid polyethylene glycol which may have a molecular weight between 1500 and 4000, synthetic gums, e.g. methyl cellulose, alkali metal carboxymethyl celluloses such as sodium carboxymethyl cellulose, natural gums, e.g. karaya, tragacanth, agar, gum arabic, Indian gum, cherry and plum gum, carbohydrates or modified carbohydrates, e.g. sorbitol, sorbitol laurate, sorbose, sorbitan, mannitol, mannitol laurate, mannitan, dulcitol, dextrose, starch, dextrin, levulose, inositol, arabinose, beta lactose, gelatin, saccharin, sodium cyclamate, and sodium chloride.  A dried animal substance is defined as a precursor enzyme, e.g. dried placent  tissue, muscle tissue, amniotic fluid, human, bovine, sheep, horse and pig plasma which may be aged and subjected to ultraviolet irradiation.  The excipient is defined as an inorganic or organic non-toxic compound, e.g. starch, lactose, dextrose, galactose, dextrin, magnesium oxide, hydroxide and carbonate, and aluminium hydroxide. The composition which may take the form of a tablet, or a powder contained in a capsule, e.g. a gelatin capsule, may contain in addition to or in place of the dried animal substance a ribonuclease, e.g. pancreatic desoxyribonuclease and ribonuclease.

Title: Improvements in or relating to circular knitting machines
Inventor: SHAW RONALD
IPC: D04B15/32
Filed: 1958-09-16
Abstract: 867,651. Knitting. TRENT ENGINEERING CO. Ltd. Dec. 2, 1959 [Sept. 16, 1958], No. 29566/58. Class 74 (2). A circular machine for knitting hose or half-hose in string formation has jacks associated with alternate needles, and on completion of a toe pocket the normal clearing cam 3 is lowered to tuck height, as shown in full lines in Fig. 1, and a jack cam 6 raises the alternate needles to clearing height so that for two courses the needles intervening between the alternate needles tuck whereby a run resistant course is completed. Provision is then made for a draw course to be formed and for this purpose the cam 3 is raised to its normal clearing position as shown in Fig. 2. Also a double cam 8 capable of lowering the needles twice in succession by being provided with two needle lowering surfaces 9 and 10 is provided and first causes all of the needles which have knitted at the previous station to be lowered by the surface 9. A jack cam 12 then raises all the alternate needles to clearing height and the surface 10 immediately lowers them so that they cast off their loops. Subsequently the intervening needles are raised by needle cam 14 and the alternate needles are raised, through their jacks, by cam 15, the latter bringing the needles into the range of a latch opener which is desirable since the needles associated with the jacks are devoid of loops. The welt for the next hose is subsequently commenced and has an elastic insert which initially is fed so as to be taken by the needles raised by the jacks at the cam 12 and which needles knit the elastic yarn at cam surface 10. Subsequently, the jack cam 12 is lowered to tuck height and the elastic yarn is taken but not knitted by the needles. The elastic yarn is eventually withdrawn and knitting is continued until the completion of the article.

Title: Improvements in or relating to pelleting carbon black and apparatus therefor
IPC: C09C1/58
Filed: 1954-10-15
Abstract: In the granulation of hot carbon black, e.g. at a temperature of 150-300 DEG F., in a rotating mill, sufficient water, e.g. 2-24 per cent, is sprayed into the mill to produce <PICT:0775378/III/1> a granulated product at a temperature of 100-225 DEG F., but insufficient to produce a water content of greater than 1 per cent. The water may contain a wetting agent, e.g. one listed in Ind. Eng. Chem. Vol. 33, No. 1, pages 16-22 and Vol. 35, No. 1, pages 107-117 and 126-130.  Water vapour may be withdrawn from the mill during the spraying.  The rate of flow of spraying water may be regulated in response to deviations in temperature of the granulated product.  As shown a rod 17 supported on piers (not shown) outside the mill passes axially through the mill.  It supports spray head 19, a scraping device (not shown) and exhaust line 22.  Loose black is delivered to the mill direct from a carbon black furnace via hopper 27 and the granulated product passes through openings 31.  The delivery end of mill 11 is covered by a gas tight hood 33 which is connected to a screen 36. Material passing through the screen is recycled to the process via conveyer 39, while the desired product is passed along a conveyer in a housing 38 and then through an elevator and shoot to a storage tank (not shown).  Three alternative means for exhausting the water vapour are shown, i.e. from the mill 11 via line 22, from the hood via line 20, and from the elevator housing 38 via line 61.  The exhausted vapour passes to a blower 56 and a filter 57, carbon black fines being recycled to the process via line 58. Mill hood 33 may also be vented directly to the atmosphere via line 20b.  A solenoid 51 cuts off the flow of water when the motor 14 stops and a valve 52 should the pressure of water drop below a certain minimum (e.g. due to leakage in the mill).

Title: Improvements in or relating to semi-conductor diodes
Inventor: BEALE JULIAN ROBERT ANTHONY
IPC: H01L21/00
Filed: 1954-10-18
Abstract: 820,611. Semi-conductor diodes. MULLARD RADIO VALVE CO. Ltd. Aug. 12, 1955 [Oct. 18, 1954], No. 29916/54. Drawings to Specification. Class 37. A semi-conductor diode comprises a semiconductor single crystal which is thicker than the diffusion length of minority carriers and in which the lifetime of minority carriers is less than 5 Á seconds. A crystal in which the lifetime is less than 5 Á seconds may be made from a bar of Sb doped N-type Ge of 0.4-2 ohm cm. resistivity, obtained by zone levelling, by .electrolytically coating it with Ni circa 0.1- 100 Á thick, heating at 700-800‹ C. for 2-5 hours in an inert atmosphere such as nitrogen, and cooling over a period of 10 minutes to an hour to room temperature. The bar is then cut into slices 30 thou. thick and an alloy junction electrode is formed by fusing a blob of In to one face of the slice, an ohmic nickel solder electrode being provided on the other face. The desired lifetime may also be obtained by using Cu or Fe instead of Ni, Cu also acting as an acceptor impurity. The lifetime may alternatively or additionally be obtained by a surface treatment such as sand blasting or etching in a fluid containing ions such as Cu which increase recombination rate at the surface, by bombardment with electrons and neutrons, or by heating to a high temperature and cooling quickly. As a further alternative suitable material is obtained by placing measured amounts of impurity materials determining conductivity and lifetime respectively, e.g. Sb-Ge alloy and Cu on a bar of Ge in contact with a seed crystal and obtaining a. uniform crystal therefrom by zone levelling. Alternatively a single impurity which controls both conductivity and minority carrier lifetime may be used in this process.
