Title: Process for the manufacture of mixed ethers of carbohydrates
IPC: C08B11/193
Filed: 1928-12-19
Abstract: 326,865. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Dec. 19, 1928. Right to Patent relinquished. Carbohydrate ethers are obtained by the action of a mixture of alkylating agents, comprising a methyl or ethyl compound and an alkyl compound of which the alkyl group contains three or more carbon atoms, upon a cellulose, starch or other colloidal carbohydrate in the presence of caustic alkali. The mixed ethers have a marked strength and insensitivity to water and are suitable for making artificial silk, films, and plastic masses. In examples, cotton linters or purified pine wood cellulose are mixed with excess of 50 per cent caustic soda solution and heated with a mixture of ethyl chloride and propyl or butyl chloride at about 120‹ C. When the reaction is complete the excess of alkyl chlorides is distilled off and the crude product is washed with water. The mixed ethers are soluble in alcohol-benzene mixtures, and possess high tearing strength and low water expansion. The proportions of ethyl chloride and propyl or butyl chloride may be varied and products having ethoxy content of 33 per cent, propyl-oxy content 12 per cent, or ethoxy content 32 per cent, butyl-oxy content 14 per cent may be obtained. Specifications 6035/13, 164,374, [both in Class 2 (ii), Cellulose &c.], and 184,825 are referred to.

Classes 1(1) and 90 Water is added to spent absorbent charcoal, to form an aqueous dispersion and this aqueous dispersion is then introduced into a reaction zone together with a free oxygen-containing gas. The amount of oxygen introduced in the reaction zone is that stoichiometrically required to oxidize the combustibles absorbed on the surface of the absorbent. The reaction zone is maintained at a temperature of from 125 to 200C. and preferably at 160 to 190C. and the pressure in the reaction zone is the vapour pressure of the reaction mixture at that temperature. Within the reaction zone the absorbed combustibles will be oxidized and converted to gaseous, liquid or solid materials which are easily separable from the now-clean surface active absorbent, and the latter is removed from the reaction zone, still in the form of an aqueous dispersion. The process may be run as a continuous or a batch process. Specification 706,686 is referred to.

Abstract: 861,870. Zeroizing mechanisms. UNITED GAS INDUSTRIES Ltd. Dec. 5, 1958 [Dec. 6, 1957]. No. 38099/57, Class 106 (1). A counter comprising a plurality of coaxial numeral wheels in which zeroizing is effected by moving apart the transfer pinions and numeral wheels and rotating the numeral wheels manually to zero is provided with a removable comb adapted to restrain the transfer pinions against rotational or axial movement during the zeroizing operation. As shown, Fig. 1, transfer pinions of the usual long and short teeth type are mounted on a shaft 3 carried by a support-member 4 pivotally mounted on a spindle 7. A comb 12, Fig. 6, has flanges 13 which fit over the lateral limbs 5 of the supportmember 4 and has a plurality of fingers 16 curved to fit between the wide teeth of the transfer pinions 9. A drum-braking comb comprising a series of fingers 18 is attached to the support-member 4 or alternatively is attached to the comb 12. To zeroize the counter the comb 12 is fitted and the supportmember 4 is rocked to move the transfer pinions away from the numeral wheels which may then be manually adjusted to zero, the fingers 18 acting as brakes. When the member 4 is rocked back to its operative position, the transfer pinions are in the correct position for re-engagement. In a counter in which the numeral wheel spindle is rocked for zeroizing, the comb may co-operate with the counter housing. As described, the comb 12 fits loosely on the member 4 so that if it is accidentally left in position, the transfer pinions are not locked. If the comb 12 is clearly visible when in position, a firm fit, by means of dimples cooperating with recesses or by forming the comb as a magnet, is possible.

Filed: 1963-09-28
Abstract: 1,103,621. Gyroscopic apparatus; electric control systems. ELLIOTT BROS. (LONDON) Ltd. Sept. 28, 1964 [Sept. 28, 1963], No. 38300/63. Headings G1C and G1N. In an autostabilization system, which may be used in combination with a hydraulic actuator of the kind described in Specification 1, 072, 525 (see Division G3), a plurality of gyroscopes are used in conjunction with duplicated power supplies, in such a way that the failure of one gyroscope or power supply causes switching means to operate to disconnect the faulty unit. As shown, Fig. 1, a system comprises two separately powered units A, B each containing a pair of gyros, 11, 13 and 12, 14, giving outputs g 1 , g 2  and g 3 , g 4  respectively, dependent upon movements about axes no two of which are coincident; for example, the axes may point N, SW, SE, and W respectively, the gyro outputs representing p; - (p + q)/#2; (q - -p)/#2; and -q, respectively, where p = roll rate and q = pitch rate. Signals g 1 , g 2  are summed in summing amplifiers 15, 17 in Unit A, while signals g 3 , g 4  are summed in summing amplifiers 16, 18 in Unit B. Sign-changing amplifiers 19, 20 in Units A, B respectively are fed with signals g 2  and g 4 . Each unit supplies four outputs, two (P 1 , P 2  and P 3 , P 4 ) relating to roll rate, and two (Q 1 , Q 2  and Q 3 , Q 4 ) relating to pitch rate; in normal operating conditions the outputs of each unit are derived from the gyros of that unit. Each of the four subsets comprising three of the four gyro signals g 1 ..... g 4  is supplied to a different monitoring circuit 21, 23 (in unit A), 22, 24 (in unit B), so that the net output of each monitoring circuit is normally substantially zero. If one gyro fails, the outputs of three of the four monitoring circuits 21.... 24 exceed a threshold value; the outputs of the two monitoring circuits in the unit containing the faulty gyro now differ from one another; this difference is detected by a logic circuit 27 (in unit A) or 28 (in unit B), which causes a pair of normally energized relays 29, 31 (in unit A) or 30, 32 (in unit B) to fall back. This results in the contacts of the de-energized relays adopting the positions shown in Fig. 1, in which state the outputs of the unit containing the faulty gyro are derived from the gyros of the other unit. Failure of the power supply of one unit produces an output from a power monitoring circuit 25 (in unit A) or 26 (in unit B) which is detected by logic circuit 27 or 28, with a similar result.

Title: Vaccines obtained from protozoal flagellates
Inventor: NEAL RALPH ARTHUR
IPC: A61K39/008
Filed: 1963-10-01
Abstract: A vaccine for immunising a mammal against trypanosomiasis or leishmaniasis comprises an antigenic preparation obtained from protozoal flagellates of the Trypanosomatidae family other than those of the genus Trypanosoma or Leishmania, respectively, which are not pathogenic to the mammal to be immunised and an adjuvant therefor. The Examples describe the preparation of vaccines from flagellates of species of the genus Leptomonas and Crithidia. The preferred adjuvants are a saponin preparation and a higher alkyl quaternary ammonium compound.  The antigen preparation may be produced by killing the cells of the flagellates, e.g. by successive freezing and thawing, by freeze drying, by ultrasonic waves, or by treatment with formaldehyde; alternatively, the protozoal flagellates may be grown in a culture medium and the antigenic material may be isolated from the medium itself by appropriate techniques.  The vaccines may contain conventional excipients, e.g. bacteriostats or buffering agents.

Abstract: 901,339. Wrapping machines. FORGROVE MACHINERY CO. Ltd. Nov. 1, 1960 [Nov. 18, 1959], No. 39154/59. Class 94(1). A continuously operating twist wrapping machine includes a twisting head having pairs of grippers for holding partially wrapped articles and two pairs of twisting jaws co-operating with each pair of grippers, the gripper pairs being rotatable relative to the head. Confectionery tablets 10 are fed by a continuously rotating feed disc 11 to be lifted by one or more lifting plungers 13 into the path of lugs 15 on a conveyer chain 16. The tablets are pushed continuously along a channel 14 to a folding box 18 and are drawn into the folding box by a continuously moving web 17 of heat sealable wrapping material. The edges of the web are brought together by the folding box to form a fin extending upwardly from the top of the box. This fin is gripped by a pair of driven sealing rollers 19 which draw the fin between heated surfaces 20 to soften it so that it is sealed under the pressure of the rollers. The tube is severed into single wrapper lengths each containing a tablet by a pair of rotating cutters 21, 22 which are then fed by slightly faster moving belts 27, 28 which produce gaps 29 between them. The wrapper lengths are picked up at A by means of grippers 31 on a continuously rotating head 32. The head includes a pair of twister drums 34 mounted on opposite sides of a pocket wheel assembly 35, the wheel and the drums rotating with equal angular velocity about a common axis. Associated with each pair of grippers 31 are two pairs of twister jaws 33 each pair being mounted for continuous rotation about shafts 48 mounted on the drums 34. After a length has been picked up by the grippers 31 the latter are rotated through 90 degrees as the head moves from A to C. This presents the ends of the tube to the jaws 33 for twisting. At position B the grippers 31 release the wrapped article, finally rotating back to their initial position. All the above operations are controlled by cam means. The distance between the pairs of twister jaws can be adjusted to suit the length of the wrapper. In modifications of the machine the edges of the web are overlapped so as to form a tube without a fin, belt conveyers providing traction for the web. The co-operating belts 27, 28 may be replaced by a single perforated bottom belt which travels over a suction chamber, Fig. 2 (not shown).
