Abstract: 689,263. Hypodermic syringes. HUSLER, S. HERTIG-, and HERTIG, W. Oct. 3, 1950 [May 25, 1950], No. 24177/50. Class 81 (ii). A piston syringe is provided with a casing having a lower supporting flange and enclosing a glass barrel against the upper rim of which a sealing cap for the casing abuts, a needle holder being clamped between the supporting flange and the barrel, contiguous faces of the needle holder and the barrel being in the form of truncated cones. A glass cylinder 1 is provided with upper and lower conical rims 7, 8. A connecting piece 24 for a needle has a conical bearing surface 26 which is held against the lower conical rim 8 of the cylinder 1 by a flange 14 of the cylinder casing 9. The casing 9 has internal screw threads 11, 12 near its upper end either of which may engage with an external screw thread 21 on a sleeve 20 projecting from a head 15. When the lower screw thread 12 on the casing 9 is in engagement with the screw thread 21 on the sleeve 20, the upper rim 7 of the cylinder bears tightly against a conical lower rim 23 of the sleeve 20 and the connecting piece 25 for the needle is held tightly against the lower rim 8 of the cylinder 1. On adjusting the head 15, the upper screw thread 11 of the casing 9 may be brought into engagement with the screw thread 21 on the sleeve 20 so that the parts of the syringe are loosened for sterilisation, the sterilising means being introduced by holes 22 in the sleeve 20. In a modification (not shown) the casing 9 may be externally screwthreaded near its upper end and the projecting sleeve may form part of a closure cap for the syringe.

Patent GB-900257-A (GB)
Title: Electric computing apparatus
Inventor: GILL JOSEPH
IPC: H03M1/00
Filed: 1959-07-17
Abstract: 900,257. Electric analogue computers. HAGAN CHEMICALS & CONTROLS Inc. July 17, 1959, No. 24704/59. Class 37. A computer for providing an output proportional to the product of two input voltages or to the product of a function or functions of said input voltages comprises a resistance network consisting of a number of sections, the required number of sections being connected in circuit in accordance with pulses corresponding in number to one input voltage, the other input voltage being applied across the resistance sections so switched into circuit, so that the voltage across an output resistor of negligible resistance connected in series with said resistance sections is proportional to said product of the two input voltages. In the embodiment shown (Fig. 1), one input voltage (E1) is compared with a reference voltage E2 in the form of a negative going sawtooth waveform derived from reference voltage generator 15 in section B of an amplitude comparator 12, section A being also provided with the reference waveform. A pulse generator 67 delivers negative pulses to input terminal 73 of the resistance network 74 through a gate valve 63 which is cut off until the sawtooth reference voltage applied to section A equals the other reference voltage (i.e. ground) applied thereto, when valve 63 is driven (through multivibrator 58) into conduction and pulses are delivered at 73. This will continue until the negative-going sawtooth reference voltage applied at 13 to section B of comparator becomes equal to input voltage E1 applied at 10, when gate valve 63 is cut off, thus stopping any more pulses from reaching 73. In accordance with the number of pulses delivered at 73 which number is proportional to the value of E1, a number of resistances 103 &c. of the various sections S1 S2 of network 74 are switched into circuit by relays 97 &c. operated through double diodes and triodes 75, 84 respectively. The second input voltage E3 is applied at terminal 105 across the resistance sections switched into circuit, and the voltage across low output resistor 107 in series with resistors 103 &c. will therefore be proportional to E1 x E3. By making the output from reference voltage generator 16 of parabolic instead of sawtooth waveform, a number of pulses proportional to #E1 may be delivered to 73 so that the output at 108 will be proportional to #E1 X E3. Alternatively, by changing the slope of the reference generator, the output at 108 can be made proportional to E1, E3/E2.

The pitch diameter ratio of the suns 70, 74 and of the rings 72, 76 is in each case greater than unity.  Ratios are as follows. First (one-way), brake 104 on reaction ring 76; one-way drive through 52 to input sun 70; planets 80 act alone. Second (one-way), brake 98 on reaction sun 70; one-way drive to input sun 70; planets 80, 88 effective. Third (two-way), clutch 57 to input-reaction ring 72; brake 98 on reaction sun 74; all three planets 80, 84, 88 effective. Fourth (two-way), clutches 53, 57 together for direct-drive lock up. Reverse (one-way), brake 66 on input reaction ring 72; one-way drive to input sun 70; planets 80, 84 effective. Two-way first, second and reverse are obtainable by engaging the clutch 53 to lock up the one-way clutch 52. An alternative second ratio (two-way) is by engaging the clutch 57 to drive the inputreaction ring 72, and brake 104 on the reaction, ring 76. The one-way clutch 52 overruns and the planets 80, 84 are effective. Two examples are specified with numbers of teeth and ratios, in each case the output speed increment at constant input speed being approximately constant for each shift, as opposed to geometric steps, an example of which is also given.

Patent GB-729208-A (GB)
Title: Improvements in or relating to a new antibiotic p.a. 95 and the preparation thereof
Filed: 1951-10-24
Abstract: A new antibiotic named P.A. 95, effective against mycobacteria, is produced by growing in a nutrient medium a P.A. 95 producing strain of Streptomyces roseochromogenus of the type described with reference to isolate No. 7143-3, or a mutant thereof.  PA95 is acidic forming metal, ammonium and organic amine salts; melting-point 138 DEG  C.; empirical formula C9H15NSO3; sparingly soluble in water, soluble in methanol, acetone, chloroform and butanol; <FORM:0729208/IV (b)/1> (2 per cent aqueous sodium bicarbonate); characteristic infra-red absorption spectrum.  Nutrient medium consists of carbohydrate source, e.g. starch, glycerol or sugar; organic nitrogen source, e.g. soybean meal, wheat gluten, cottonseed meal or protein hydrolysates; growth promoter, e.g. distillers' solubles, yeast extract, vitamin source; buffer, e.g. calcium carbonate; and antifoaming agent, e.g. lard oil, soybean oil or silicone.  The micro-organism is grown under submerged conditions of agitation and aeration at 24 DEG  to 30 DEG C., preferably 28 DEG  C., for 2 to 7 days at approximately pH 7.0. The antibiotic may be isolated by (a) treating the filtered broth with activated carbon and eluting the antibiotic from the separated carbon by means of aqueous-solvent mixtures, e.g. acetone-water; (b) adsorption on strongly basic or strongly acidic ion-exchange resins, e.g. "Amberlite" (R.T.M.) I.R. 120 and I.R.A. 400, and eluting therefrom with a solution of an inorganic salt, e.g. ammonium chloride or ammonium sulphate; and (c) extracting the broth at a pH 2.0 with a water-immiscible solvent, e.g. butanol, amyl alcohol or benzyl alcohol, and thereafter extracting at a pH 9.0.  After the removal of the solvent, the eluate of (a) may be further purified by method (b). The eluate of (b) may be freeze dried, or the pH adjusted to 4.5, dried and extracted with chloroform.  The crystalline antibiotic may be obtained by evaporation of the chloroform extract, or the addition thereto of a non-solvent, e.g. hexane.  The antibiotic may be dissolved in hot ethylene dichloride filtered through charcoal and cooled.  The ammonium salt is produced by bubbling anhydrous ammonia through a solution of the acid form of P.A. 95 in ether.  The sodium salt may be prepared by dissolving the antibiotic in sodium bicarbonate solution.

[Class 40 (v).] In a supersonic heterodyne receiver in which the aerial circuit, the local oscillator circuit, and the intermediate or resultant frequency circuit, are tuned by ganged condensers, the inductances L1, L2, L3 of the three circuits are so chosen that the inverse square root of L3 is equal to the difference (or sum) of the inverse square roots of L1 and L2. In this way, the three associated capacities can be made equal to each other throughout the tuning range, and the design and ganging of the condensers is facilitated.
