Abstract: 738,416. Feeding metal strip. CLARK & SONS (TOOLMAKERS), Ltd., G. F., and CLARK, G. F. March 18, 1954 [March 27, 1953], No. 8514/53. Class 83 (4). In a device for feeding metal strip to machinetools such as punch presses, in which a feeding blade is reciprocated by the machine-tool, the strip is held in engagement with the feeding blade by a manually-operable clamp which can be released to allow the strip to be removed from or inserted into the side of the feeding device. A reciprocable carrier 12 sliding on a member 13 secured to the base 1 carries a sleeve 36 in which is eccentrically journalled the feeding blade 11 so that rotation of the sleeve 36 adjusts the height of the feeding blade 11. A crank 10 secured to the feeding blade is cornected to a spring-loaded lever 5 carrying a roller 6 engaging a moving member of the machine tool which imparts the forward feeding motion to the blade 11 and the carrier 12. A clamping-block 40 releasable by a handle 44 and mounted on the-carrier 12 presses the strip against the feeding blade 11. The rearward movement of the carrier 12 and thus the feeding stroke is limited by a stop 19 adjustable by a micrometer screw 20. Rearward movement of the strip is prevented by a spring-loaded blade 48 eccentrically mounted to be adjustable in height on a pivot 52 rotatable in the base 1. A clamping block 58 releasable by a lever 62 holds the strip against the blade 48. The strip is guided between rollers 66, 65 respectively mounted on the base and an adjustable slide 64. Holes 71 in the base 1 and the member 13 serve to locate the feeding, device on the machine-tool.

Title: Method of purifying solutions of anti-bacterially active substances derived from the growth of micro-organisms
Filed: 1947-03-28
Abstract: Solutions of anti-bacterially active substances derived from the growth of micro-organisms are purified by adding thereto one or more chemicals capable of forming, by mutual reaction or by reaction with substances present in the solution, an adsorbent precipitate, and thereupon removing said precipitate from the solution together with impurities entrained thereby.  The precipitate and the components leading to its formation must not inactivate the active substance, suitable precipitates being those of insoluble compounds of magnesium, barium and especially aluminium, which last may be produced by addition of an aluminium salt to the solution, with or without subsequent adjustment of the pH value, e.g. to 3-8, preferably to 4.5-5.5.  The process is applicable to the treatment of actual culture media, or of solutions or concentrates produced during the preparation of more active and purer products.  In an example, aqueous ammonia is added to a culture medium containing penicillin, and then an aqueous solution of aluminium sulphate is added until the pH of the solution is about 5, and the precipitated aluminium hydroxide is filtered off and washed with water, which is added to the filtrate and the whole worked up in the usual way.  Other suitable precipitates are magnesium hydroxide and barium carbonate.

Title: Improvements in or relating to electrical testing apparatus
Inventor: DAVIS HERBERT MACDONALD
IPC: G01N27/24
Filed: 1955-03-25
Abstract: 826,726. Electric tests. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 23, 1956 [March 25, 1955], No. 8716/55. Class 37. In apparatus in which a substance to be tested for flows varies two adjacent reactive impedances so that, when their outputs are combined, comparatively long-term variations are cancelled out, interaction between the impedances is prevented by energizing them with alternating currents in quadrature. The invention is described with reference to detecting flows in a sheet M of plastics material passing between the plates of adjacent condensers C1, C2. The condensers are energized in phase quadrature from the sinusoidal output of an oscillator 1, the outputs being then fed to phase-sensitive demodulators A1, A2, also energized with the same signals as those applied to the condensers and the difference signal is indicated on a valve voltmeter V. The circuit of each of A1, A2, and the valve voltmeter is shown in Fig. 3. Each measuring condenser is connected in series with a reference condenser C3 and the signal developed across the reference is fed through a cathode follower V1, phase-adjusting arrangement R5, C5, and applied to the grid of pentode V2, the suppressor of which is fed with square pulses from generator 5 controlled by the same signal as that applied to the capacitor. Phase-adjuster R5, C5 brings the sinusoidal and square pulses into phase agreement and the mean D.C. level of the anode is determined by smoothing circuit C6, R6 and fed to the grid of triode V3 which with V4, to which a similar signal is fed from the other measuring channel, operates meter R connected between the cathodes. In each case signals from the other condenser which are 90 degrees out of phase, do not affect the mean anode voltage level. The condensers may be replaced by electromagnetic pick-up heads.

Abstract: 537,205. Automatic exchange systems. ELECTRICAL RESEARCH PRODUCTS, Inc. May 28, 1940, No. 9349. Convention date, July 11, 1939. [Class 40 (iv)] In a forward-loop impulsing arrangement, the repeating relay 103 in an outgoing repeater at each impulse closes a direct shunt across the junction 101. An auxiliary relay 105 over which current is fed to the junction is thus held, and the change of flux when the shunt is removed. produces a high voltage surge which assists the re-operation of the distant impulse receiving relay 200. Relay 103 energizes when the junction is seized, and relay 105 is connected to the junction by release relay 104. Relay 200 energizes in series with 105 and prepares the incoming selector for operation, a circuit being more for the lower biassing winding of 200. The impulses recived by 200 effect the setting of the incoming and succeeding selectors. The reversal of current at the final selector upon reply operates polarized relay 210, which by means of relay 202 inserts a resistance 210 in series with relay 200. Relay 105 which is marginal therefore relapses and connects up reversing relay 106, and at the same time closes a further locking circuit for release relay 104. Release is thus under the joint control of both parties, relay 104 being disconnected when 103 falls back and 105 reoperates.
