Title: Copolymers of episulphides
IPC: C08G75/08
Filed: 1963-02-14
Abstract: The invention comprises copolymers of at least one saturated episulphide and at least one episulphide containing at least one olefinic carbon-carbon double bond and the preparation of such copolymers by effecting polymerization in the presence of a catalyst comprising a compound of Group IIb of the Periodic Table.  The preferred saturated monomers are those containing 2-6 carbon atoms, e.g. ethylene, propylene and butylene sulphides or mixtures thereof. In mixtures involving ethylene sulphide it is preferred to limit the proportion of ethylene sulphide to less than 35 mole per cent. Suitable unsaturated monomers, which generally comprise 0.1-20 mole per cent, preferably 1-10 mole per cent, of the polymer, are allyloxymethyl thiirane, vinyl thiirane, 1,5-hexadiene-, dimethylbutadiene-, piperylene-, isoprene-, 1,4 - pentadiene-, cyclopentadiene-, limonene-, vinyl cyclohexane-, 1,3-cyclohexadiene-and 1,4-dimethylene cyclohexane monoepisulphides, thioglycidyl methacrylate and thioglycidyl acrylate.  Specified catalysts are zinc carbonate, zinc sulphide, zinc peroxide, cadmium carbonate, cadmium oxide, cadmium sulphide and catalysts formed from zinc dialkyl, e.g. diethyl, dipropyl and dibutyl, and water, the water/zinc dialkyl ratio being preferably between 0.5 and 4.0.  The chlorides, iodides, fluorides, diacetates, phosphates, nitrates and cyanates of Zn, Cd and Hg are also suitable catalysts.  Catalysts other than those based on zinc dialkyl may be activated by heating to an elevated temperature, lying below the decomposition temperature, prior to use, e.g. zinc carbonate can be heated to 140-350 DEG  C. Polymerization can be carried out in bulk or by the solution or emulsion techniques. Catalysts other than zinc dialkyls can be used in aqueous polymerization systems.  When solution polymerization is used the preferred solvents are ethers, e.g. diethyl or diisopropyl ethers; the reaction is generally carried out at reflux temperature. The copolymers of the invention can be vulcanized by known techniques. Examples describe the preparation of numerous polymers using the monomers and catalysts specified above and the vulcanization of the products in compositions comprising carbon black, zinc oxide, stearic acid, sulphur and tetramethylthiuram disulphide.

Arm 2 is secured to one edge of the door and a further support track arrangement comprising track and follower can be located at the other edge. In the Fig. 2 embodiment arm 105 is pivoted at 106 to the door and an additional follower 103 is provided at the junction of linkage 108 with the arm to engage the curved section of track 101. A further support track at the other door edge may be used in this embodiment also.

Title: Improvements in or relating to cathode ray tube circuit arrangements
IPC: H01J29/52
Filed: 1934-02-23
Abstract: 434,199. Circuits for cathode ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, and YOUNG, A. J., 61, Galveston Road, Putney, both in London. Feb. 23, 1934, No. 6034. [Class 40 (iii)] The intensity of a cathode-ray is modulated by modulating the anode voltage of the tube, and the forces deflecting the ray to scan a predetermined area are simultaneously varied in dependence on the modulating-potentials to compensate variation in the speed of scanning resulting from modulation of the anode voltage. The signals, which also produce the anode modulation, are applied to the grid 3 of a pentode rectifier, and potentials from a tapping 9 in an anode impedance R1 are applied to the control grid 12 of a pentode amplifier to vary its mutual conductance. Potentials 10 from a time-base circuit are applied across an impedance R2 between the tapping 9 and the grid 12. The anode circuit of the amplifying-valve provides the force for deflecting the cathode ray. According to modifications ; the tapping 9 is on an impedance between the cathode 2 of the rectifier and the negative end H.T. of the source of anode potential ; the compensating device is combined with the time-base unit, Fig. 2 (not shown).

Filed: 1935-02-27
Abstract: 445,138. Time switches. GIORDANI, A., and GIORDANI, A., 2, Corso Garibaldi, Padua, Italy. Feb. 27, 1935, No. 6249. Convention date, Feb. 27, 1934. [Class 38 (v)] Insertion of a finger in a selected hole of a selector disc 1 and rotation of the latter till the finger abuts against a stop 4 after the manner of an automatic telephone winds up a spring 10 ; when the finger is withdrawn the disc rotates backwards and operates a switch, which remains in the " operated " position for a time determined by the hole selected. The stop 4 is yieldingly mounted so that it may be pressed to the dotted position by the finger to impart an additional movement to the disc 1 corresponding to half a time unit. The device is specially applicable in photography. The disc 1 is fixed to an axle 6 which is controlled by the spiral spring 10 and the axle 6 has also fixed to it a plate 11. Pivoted at 14 on the plate 11 is a lever 13 carrying at one end a pawl 15 and at the other a spring urged contact 2 which is adapted to engage contacts on a contact carrier 12 on the plate 11. A spring 16 tends to hold the lever 13 in the position shown in Fig. 4. When the finger rotates the disc 1, the disc 11 moves counter-clockwise, Fig. 4, and the pawl 15 slides over the teeth of a ratchet wheel 19. When the finger is withdrawn, the spring 10 rotates the discs 1, 11 backwards and the pawl 15 engages the wheel 19 which is connected wtih a train of gearing. The resistance to movement of the wheel 19 causes the lever 13 to be moved about its pivot 14 and the contact 2 to be moved into its alternative position against the action of the spring 16. The pawl 15 then drives the wheel 16 and its train of gearing till after the predetermined time the pawl is lifted from engagement with the wheel by a stop 21. The spring 16 then restores the lever 13 and contact 2 to their original position.

Title: Process for the isolation of a polyvalent proteinase inhibitor
IPC: C07K14/81
Filed: 1975-02-14
Abstract: The production of a polyvalent proteinase inhibitor from animal organs, in particular from lung, is carried out by adsorbing the inhibitor from its aqueous solutions by adsorption on an ion exchanger having functional sulphonate or phosphonate groups at pH 0.5 to 10.5 and eluting it with water or a salt solution at pH 1 to 13. A suitable adsorbent, in particular, is an ethenesulphonate/ acrylamide copolymer gel, as is obtained by copolymerisation of ethenesulphonic acid and acrylamide in the weight ratio 20:1 to 2:1 and subsequent crosslinking with 1 to 15 % formaldehyde. Further suitable adsorbents are polyphenolomega -sulphonic acid resins and also polystyrenesulphonic acid resins and polystyrene phosphonic acid resins. The inhibitor obtained by this process is suitable for therapeutic use on account of its high degree of purity. It can additionally be employed, for example, as a stabiliser for standardised protein preparations.

To relieve the strain on the rams when the container is in the carrying position a rod 35 is placed between the frame and one rocker arm, the rod dropping clear when the bowl is tilted rearwardly. An end gate 29 is pivoted at 30 on extensions of the rods 21, an adjustable stop limiting its movement. Each pivot 30 is so positioned that the container is in a scraping position it is on one side of a line joining the pivot 27 and the point of closure between the body and the tailgate and in the carrying position is an equal distance on the other side of this line so that on raising the bowl the gate is loosened to prevent jamming. By means of links 42 the frame may be lowered with respect to the wheels when the bowl is in a scraping position.
