Title: Process for the production of high molecular weight alkali-soluble polycarbonates
Filed: 1957-05-22
Abstract: New linear polycarbonates soluble in organic solvents and aqueous alkali solution contain the residues of organic dihydroxy compounds with carboxylic or sulphonic acid groups and side chains.  They are made by reacting organic dihydroxy compounds containing such acid groups, if desired in admixture with other organic dihydroxy compounds, with bis-halocarbonic esters of organic dihydroxy compounds or phosgene.  Specified dihydroxy compounds containing acid groups are tartaric acid, dihydroxy stearic acid, 2,5-dihydroxy-cyclohexane carboxylic acid, 4,41-dihydroxy-dicyclohexyl - dicarboxylic acid - (2,21), 2,6 - dihydroxy benzoic acid, 3,6-dihydroxybenzenedicarboxylic acid-(1,2), 4,41-dihydroxydiphenyldicarboxylic acid-(2,21), 4,41-dihydroxy-3,31-dicarboxy - diphenyl - methane, 4,41 - dihydroxy - 3,31 - dicarboxy - 5,51 - di -methyl - diphenylmethane, 1,4 - dihydroxybenzene - sulphonic acid-(2), 1,6-dihydroxy-naphthalenesulphonic acid-(3) and 4,41-dihydroxy-diphenyldisulphonic acid-(2,21).

Title: Improvements relating to slicing machines
IPC: B26D7/02
Filed: 1934-06-01
Abstract: 433,819. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., and THOMAS, H., Aden Road, Ponders End, Middlesex. June 1, 1934, No. 16349. [Class 28 (ii)] A last-slice holder is provided at one side with means for attachment to a feed part of the machine, and with locking means which act automatically to lock the holder to the feed part when it is positioned thereon. As described, the feed part is a clamp post. In Fig. 1, the holder G is pivoted at 16, for angular correction, to a bracket having upper and lower limbs 11, 12 each having an open sided bearing 13, which embraces the clamp post E. The bottom bearing 13 embraces an enlarged bottom part E <1> of the post, and a lug 15, extending from the bearing, is apertured to receive a pin 17 upstanding from the feed table. The holder and its bracket are manipulated by a handle 18, and when the bracket is applied to the post E, it is locked by a part - circular, tilting friction collar 20, Fig. 3, which is urged by an arm 21 of a lever 22 to grip the post. A spring 23 housed in a recess in the lever 22 and bearing against the limb 11 of the bracket to which the lever 22 is pivoted, tends always to maintain the collar 20 in its locking position. To remove the bracket from the post, the thumb piece 22<1> of the lever 22 is depressed when the handle 18 is gripped, thus allowing the weak spring 27 to release the bite of the collar 20 on the post. The prongs of the holder are operated by the hand lever H e.g. as described in Specification 337,572, [Class 28 (ii)]. The automatic angular correcting movement of the holder G may be effected by mechanism J e.g. as described in Specification 435,338. In a modification, the automatic locking of the bracket on the post is effected by a spring- urged sliding bolt, the nose of which enters a groove, hole or other recess in the post. The bolt has a side projection to enable it to be withdrawn from the groove when the handle 18 is gripped for manipulation of the holder. In another modification, a pivoted friction cam or pawl is urged by a spring contained in a telescopic rod into locking engagement with the post, the cam being released from the post by gripping a lever, pivoted to the outer sliding part of the telescopic rod. Alternatively, the cam or friction pawl is replaced by a pivoted pawl which engages one of several notches in the post.

Filed: 1975-04-22
Abstract: 1509422 Electro-chemical measurement system SIEMENS AG 22 April 1975 [28 June 1974] 16689/75 Heading G1N A sensor for measuring the concentration of a physiological fluid constituent comprises a catheter 1 with a sensing electrode 2 near the outlet 5 of the passage 4 and means for supplying a flushing fluid which contains a reference amount of the constituent down the passage to clean the electrode and provide a concentration reference. Preferably the constituent is oxygen and the flushing fluid is saline solution. Flushing fluid 9 containing a known concentration of sterile air is fed to catheter 1 via pump 7 which may also be reversed to suck body fluid on to sensor electrode 2 so that unknown and reference readings alternate. The sensor electrode is a noble metal (preferably gold) with a membrane cover. For calibrating the cell output, another gold sensing electrode 16 and a common reference electrode 17 are arranged in the flow of flushing medium. The reference electrode (Ag/AgCl) may also be located on the patient's skin. The reference gas may be bubbled into the flushing medium until a standard concentration is reached. In an alternative embodiment, the proportions of air and nitrogen fed to the flushing medium via a gas exchanger may be varied in accordance with the cell output so that the reference value tends towards the measured value.

In a fire-arm the barrel is formed with a cartridge chamber 8 provided with a liner 7 slidable axially to a limited degree in the chamber 8 to facilitate extraction of the cartridge case 3. The liner 7 slides between two fixed abutments 9, 10 and the wall of the chamber 8 is lubricated with molybdenum bisulphite to facilitate the sliding movement of the liner 7 which is made of tempered and reheated spring steel or nitrided steel. The outer wall of the liner 7 and the inner wall of the chamber 8 are tapered as shown, and the liner 7 is also given a radial resiliency which permits it to expand on recoiling to its rear position, thus facilitating release of the cartridge case. The radial resiliency may be obtained by giving the liner and chamber such relative dimensions that the liner undergoes an internal stress when fully engaged in the front position. Alternatively, the liner 7 may be provided with longitudinal slits 7a, Fig. 4. The front inner wall of the liner 7 is of frusto-conical shape having an apex angle slightly smaller than that of the cartridge case neck 3a.

Abstract: 542,860. Methacrylic acid esters. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 29, 1940, No. 17038. Convention date, Dec. 1, 1939. [Class 2 (iii)] Esters of α-methacrylic acid are obtained by re-acting the corresponding esters of xhydroxyisobutyric acid with phosphorus pentoxide in the presence of a phosphate ester. The α-methacrylic esters may be separated by distilling the resulting re-action mixture. Aliphatic phosphates, e.g. tributylphosphate, cycloaliphaticphosphates, e.g. tricyclohexylphosphate and aromatic phosphates, e.g. tricresylphosphate may be used. It is desirable to conduct the re-action in the presence of a substance which inhibits the polymerization of the methacrylic ester. Examples of inhibitors are copper, copper-bronze, copper acetate, phenol, cresol, pyrogallol, hydroquinone, resorcinol, tannic acid, sulphur and selenium. In an example, ethyl-α-hydroxyisobutyrate is slowly added to a mixture of tricresylphosphate, phosphoruspentoxide and copper-bronze heated under reflux. The following esters are specified : methyl, propyl, butyl, amyl, decyl, dodecyl, tetradecyl, cetyl, octadecyl, phenyl, cresyl, tolyl, benzyl, resorcinyl and naphthyl-x-methacrylates.

Breaking and scutching apparatus.-Flax and like fibrous plants are cleaned and prepared by passing them between fluted members 39, 39<1>, Fig. 2, which break the woody matter and bend the stalks. The direction of motion of the members is then reversed and the stalks are folded back upon themselves as shown in Fig. 3, and are subjected to end thrusts. The forward movement is substantially twice the backward movement. This process is repeated several times and the stalks finally cleaned by beaters 41, Fig. 5. The fluted members 35, 38, 39, the flutings on which gradually decrease in size, are driven by a rack 27 reciprocated vertically by a crank 24 operated by a treadle 21. The gear 29 meshing with the rack is loose on the spindle 34 and carries a ratchet 32 coacting with pawls 30, one on each side, which are controlled by a cam to give the required variation in the forward and backward movements. The other fluted members are driven from the spindle 34 by a chain 37. The beaters 41 are driven by a chain 42 from the wheel 23. The stalks are fed in vertically through a hopper 20.
