Abstract: 1,190,444. Rack mounted electrical equipment. VERO ELECTRONICS Ltd. 15 May, 1968 [15 May, 1967], No. 22451/67. Heading H1R. In a rack for accommodating circuit cards 10 or module frames grooved 9 guide members 8 extending between front and rear longitudinal members 6, 7 connecting end plates, Fig. 1 (not shown), are provided with tongues 13 which co-operate with corresponding grooves 13A in the members 6, 7. The assembly of the rack is effected by first attaching longitudinal members 6, 7 to one of the end plates 5 by screws. The guide members 8 can then be slid into engagement with corresponding grooves 13A in the members 6, 7 after which the other end plate is screwed into position. The guide members 8 may form an integral structure extending the length of the rack or they may be in single units, each being provided with one groove and being separated by spacers in grooves 13A. The rack may be constructed to have a greater depth from front to rear by including a pair of central longitudinal members attached to the end plates, Fig. 6 (not shown), so as to permit the fitting of two rows of guide members 8 extending end to end. In order to cover the top and bottom of the rack to exclude dust or provide electrical screening longitudinal grooves can be provided in the members 6, 7 into which cover-plates are slid. The printed circuit cards 10 are held in position by a member 30, Fig. 7, which fits into a corresponding groove 31 in the members 6 and is biased by a spring 32 to the position shown in which projection 33 on member 30 abuts a circuit card 10. When the member 30 is depressed and pivoted a card can be removed. A panel 35 carrying electrical equipment may be retained by recess 36 in member 30. The cards co-operate with edge connectors 11 which are retained in the rack by ears 17 which fit into recesses between flexible projections 14 at the rear of guide members 8 and by retaining strips 16. In an alternative arrangement shown at the top of Fig. 3 the projections 14 on members 8 are shorter and the strip 16 is replaced by a rigid bar 18A held in position by screws 27. In the arrangement of Fig. 8 (not shown), the ears of the edge connectors are attached by screws to a plate which covers the whole of the rear of the rack and is attached to the members 7 by nuts and screws similar to Fig. 3. The circuit cards 10 may be replaced by a drawer module unit, Fig. 9 (not shown), which carries at its inner end plug-type connectors which co-operate with a socket-type connector mounted on the rack.

Title: Improved process for the recovery of proteolytic enzymes from pancreas gland material
IPC: C12N9/64
Filed: 1953-08-18
Abstract: Proteolytic enzymes are recovered from pancreas gland material in association with aqueous organic solvent (e.g. the residues from insulin extraction) by forming a slurry containing enough water to solubilise the enzymes and an acid capable of disintegrating the glandular solids and separating the liquid phase containing the enzymes, there being present before the separation of solid and liquid phases sufficient of an inorganic salt to cause coalescence of the disintegrated solids, the salt being of the type that precipitates globulins from aqueous alcoholic solution at lower salt concentrations than albumins. In preferred methods of operation the starting material comprises p  the glandular solids in aqueous methanol, ethanol or acetone (containing 50-85 per cent of organic solvent) acidified with phosphoric, hydrochloric or oxalic acid to pH below 4.  This is diluted with water to reduce the organic solvent concentration to 2-25 per cent (preferably 2-15) and digested to dissolve the enzymes.  Ammonium sulphate is then added to a saturation of 0.005-0.4 (preferably 0.005-0.03) and the solid and liquid phases separated by centrifugation.  The separated solids are again treated with water which with the acid and organic solvent carried over by the solids forms an acid extracting liquid containing less than 5 per cent of organic solvent.  Ammonium sulphate is now added to a saturation of 0.02-0.05 and the solid and liquid phases again separated.  The combined extracts (containing 4-8 per cent of organic solvent) are treated with more ammonium sulphate to give a saturation of 0.05 or more, whereby the inert contaminants are precipitated, and finally the ammonium sulphate concentration is brought up to 0.6 saturation to precipitate the enzymes.  Examples are given of the process, together with the purification of the enzymes as follows:-sufficient ammonium sulphate is added in the final step to precipitate only trypsinogen and chymotrypsinogen, these being separated by the insolubility of the latter at pH 5.0; the filtrate is re-precipitated with ammonium sulphate at pH 3.0, dried, dissolved in borate buffer at pH 9.0 and salted out with magnesium sulphate at pH 7.6 to give crystalline trypsin.  If desired, other enzymes such as ribonuclease can be precipitated by the addition of more ammonium sulphate.  Other inorganic salts that are suitable are magnesium sulphate, sodium chloride, sodium acetate, sodium sulphate and sodium borate.  The process may be combined with those of Specifications 727,610 and 727,611.

Abstract: 650,099. Non-metal resistances; temperature variable resistances. PHILIPS ELECTRICAL, Ltd. Aug. 20, 1947, No. 23080. Convention date, Aug. 23, 1946. [Class 37] Relates to manufacture of semi-conductive material and resistances comprising such material. A metal compound base containing metal ions able to occur with more than one valency is heated jointly with a metal compound having the same metalloid but having metal ions the valency of which is different from that of the metal ions of the base material so that a mixed crystal is formed in the lattice of which the metal ions of the added substance having a different valency occupy lattice positions of the metal ions of the base material and ions of the base material correspondingly change in valency. In one example the base material consists of 146.1 grams of SrC03 and 79.9 grams of Ti02 and the added compound 1.62 grams of La2O3. These materials are mixed and ground for 4 hours in a ball mill with alcohol, moulded to the required shape and sintered for 1 hour at 1100‹ C. in air and 3 hours at 1250‹ C. in pure nitrogen. In the mixed crystal formed the Ti ions are in part Ti<SP>4</SP>+ ions and in part lower valency than this consistent with La<SP>3</SP>+ ions occupying lattice positions of Si2+ ions. The material obtained possesses a specific resistance 1.7 ohm per cm.<SP>3</SP> and resistance-temperature coefficient - 0.2 per cent per ‹C. The metal ion radius in the added compound is preferably different within Œ20 per cent from the radius of the metal ion superseded in the formation of the mixed crystal. Other manufacturing examples are given and ion radii details. Specifications 36935/38, (as open to inspection under Sect 91), 464,274 and 522,660 are referred to.
