Abstract: A biologically active polysaccharide complex is prepared by proteolysing organisms of a pseudomonas species, and separating the polysaccharide from the proteolysed cellular material by dialysis, using a membrane having a porosity sufficient to pass 75 to 90 per cent of similarly proteolysed crystalline bovine albumin.  The bacteria which may be treated include the azotobacteriaceae, Rhizobiaceae, Neisseriaceae, Lactobacteriaceae, Achromobacteriaceae, Entorobacteriaceae, Bacteriaceae, Bacillaceae, Parvobacteriaceae, Brucelleae, Nitrobacteriaceae, Micrococcaceae and Corynebacteriaceae, specific examples being Eubacteriineae, Proteus vulgaris, B. subtilis, Salmonella typhosa, Serratia marcescens, Escherichia coli, Enterobactericeae, Azobacter chroococcum, Chromobacterium violaceum, Neisseria catarrhalis, Alcaligenes faecalis, and B. mycoides.  The proteolysis may be effected by means of trypsin, pancreatin, papain, polidase-5, a fish enzyme, or protease.  The dialysis membrane may be made from cellulose sausage casing, regenerated cellulose sheet, or wet regenerated cellulose gel film tubing.  After the bacteria have been grown and harvested, they may be thermally killed before the proteolysis which may be carried out in the presence of a preservative such as toluene or thimerosal.  The product is preferably buffered at a pH of 5.5 to 8.5 with for example a lactate or citrate buffer.  After dialysis the retained active material may be centrifuged or filtered and then diluted for use or dried for storage.

Abstract: 1,134,604. Two-part couplings; wire strippers. LEWARD & CO. (PROPRIETARY) Ltd. 21 April, 1967 [22 April, 1966; 15 Aug., 1966], No. 18568/67. Headings H2C and H2E. A plug connector comprises a contact-carrying base 2 and a hinged cover 1 which, when in their closed position, are separated by a gap at the hinged end of the connector, so preventing the hinge being strained by a supply cable which is clamped in a passage 8 between the base and cover. Preferably the hinge is a web 3 integral with both the base and cover and the connector is held closed by a screw 39. A flange 4 on the cover lies in a recess 5 at the unhinged end of the connector and projects beyond the base to provide a finger grip. Square terminal nuts, which are a close fit in square recesses in the base, are tightened against the supply leads by rotation of contact pins 12, 13, 14, a projection 29 on the cover gripping the supply cable insulation. Alternatively, projections on the cover clamp the leads against terminal strips which lie in channels 9, 10, 11 in the base. A fuse may be connected between a terminal strip and a contact pin. In a modification (Fig. 6, not shown) the connector is held closed by engagement of a screw-threaded extension (43) on one contact pin with a threaded aperture in the cover, the contact pins being of polygonal cross-section if desired. The hinged cover 1 includes a V-shaped wire-stripping blade 31. A wire 34 to be stripped is located in a recess 33 in the plug base 2 and the cover 1 is closed, causing the blade 31 to cut through the wire insulation (Fig. 4, not shown), the wire then being pulled out of the recess. Guards (36) on the blade 31 limit the depth of the cut in the wire insulation.

Title: Apparatus for drying moisture laden articles by dielectric heating
IPC: F26B5/04
Filed: 1947-07-15
Abstract: 629,979. Dielectric heating. RADIO CORPORATION OF AMERICA. July 15, 1947, No. 18848. Convention date, Dec. 31, 1941. [Class 39(iii)] Moist articles such as rayon cakes are dried by dielectric loss between electrodes in a vacuum chamber, a plurality of such chambers or stations being arranged to receive energy successively whereby a steady load is presented to the H.F. generator and the falling power acceptance of each individual article as it loses moisture is offset by fresh wet articles arriving at the initial drying station. Referring to Fig. 2 each station comprises a chamber 1 evacuated by a conduit 13 and provided with electrodes 5, 7, and guard rings 21, 23, outside the chamber for equalising end effects of the electric field, and a cooling coil 15 to condense moisture vapour liberated during drying. A variable condenser 11 is placed in series to control the amount of power supplied from the resonant circuit 9. Referring to Fig. 1 a plurality of such stations 1 are arranged on a rotatable platform 25 driven by a motor 27 so as to assume six positions as shown. In position 1 loading and unloading take place in positions II and III evacuation of the chamber is effected by a vacuum pump and in positions IV, V, VI, H.F. energy is supplied via condenser couplings 11a, 11b, 11c, the couplings being progressively increased to supply more energy as the power acceptance falls off at each successive station. Between stations VI and I the vacuum is broken to enable unloading to take place and the cycle to be repeated. Specification 563,590 is referred to.

Title: Improvements in percussion fuses for projectiles
IPC: F42C1/02
Filed: 1930-06-20
Abstract: 352,215. Projectile fuzes. BRANDT, E. W., 101, Boulevard Murat, Paris. June 20, 1930, No. 18858. Convention date, June 20, 1929. [Class 9 (i).] Relates to sensitive percussion fuzes in which the percussion cap 12 temporarily sets back against a spring 16 during acceleration on discharge, and consists mainly in the provision oi a braking action to slow down the forward return movement of the percussion cap. In Fig. 1, a tail 19 on the percussion cap holder 15 fits into a washer 17 which applies a braking friction to the return stroke. The washer may be made of cork, rubber, or other suitable material, and of various shapes ; for example, the central hole may be tapered or formed with annular lips, the outer periphery may be longitudinally grooved, and the annulus of the washer may be split. In Fig. 9, a ring 23 is fitted to the percussion cap holder to make an airtight fit in the chamber 2 of the fuze body, and a flap valve 24 is arranged at the rear end of the chamber, so that a pneumatic action delays the return stroke. In Fig. 10, the set-back is cushioned by a felt or other cushion 32 and the return delayed by friction by an expansible ring 30 which is wedged against . the surface of the chamber 2<1> by the conical part 28 of the percussion cap holder. In a modification, the expansible ring 30 is replaced by another having annular lips and the chamber 2<1> is enlarged at its upper end so that the braking action ceases to operate before the completion of the return stroke. The striker 3 is shaped as shown, and its rearward movement is pneumatically cushioned by the air in the chamber 7 behind the enlarged head 4 of the striker, which may be protected by a covering disc. Before the striker can reach the percussion cap it must shear a pin 9 on a ring 10, which is attached to the striker or to the percussion cap holder 15. The point 20 of the striker is preferably made softer than the covering disc 14 of the percussion cap.
