Abstract: Ethylated gelatin is prepared by adding ethyl sulphate to an aqueous dispersion of gelatin at 120 DEG F. at pH 9,5, the pH being maintained constant by the addition of aqueous sodium hydroxide. The pH is adjusted to 6,0 with 6N sulphamic acid and the dispersion chilled, noodled, washed, and dried.  Ethylated phthalyl gelatin is prepared by adding an acetone solution of phthalic anhydride to an aqueous dispersion of gelatin at pH 9,5, the pH being maintained constant by the addition of aqueous sodium hydroxide.  Ethyl sulphate is then added and the pH similarly maintained constant, and finally the pH is adjusted to neutral and the gelatin derivative separated as before.

Abstract: 411,197. Apparatus for assembling bottle &c. closures. SURE SEAL & SUTAX, Ltd., 132, Lots Road, Chelsea, and STEPHENS, W. A., 73, Pennard Road, Shepherd's Bush, both in London. Dec. 22, 1932, No. 36375. [Class 125 (iii).] Apparatus for assembling closure devices for bottles &c., comprising apparatus for associating inners and bands and means for effecting the knock down operation is characterized by inner feeding means for the apparatus having locating means to dispose an associated inner and band in position for the knocking down operation. " Inners " gravitate down a shoot 40 into a cut-away portion 41 of an oscillating plate 43, a tail 56 of which acts as a gate to allow one inner to advance at a time whilst supporting the remainder. The plate 43 carries a spring finger 45, which bears upon the inner, and a spring controlled pawl 58, the tail of which leans upon a fixed cam 65. The plate 43 is oscillated by a reciprocating link 54, with a lost-motion device 53, actuated by the system 3, 4, 7, 9, 10, 51 driven by the main shaft 2, governed by a one-revolution clutch under the control of an operator, e.g. by foot treadle. At the position shown in Fig. 3 mechanism, as described in Specification 336,302, [Class 125 (iii)], wraps a band on the inner and discharges the assemblage to a runway 47 furnished with guides 49, 50. The pawl 58 coacts with stop 57 to hold the associated band and inner for action thereon by the knock-down tool 146, which is driven by the main shaft 2 through an adjustable connecting rod 62, 64. In case of a jam, in either half of a revolution, the actuating mechanism 3, 4, 7, 9, 10, 51 is provided with " give " connections ; at 18, a spring clamp, and at 14, 17, a spring pressed pin 17 which will allow the pin 15 of the rocker 4 to ride in a slot 14. The one-way clutch, governing the main shaft 2, is actuated by a claw 29, on a collar 31, attached to a foot treadle lever system 21 .... 27, which moves a trip member 35 to release a spring- urged clutch member 36. Immediately the claw has been moved a cam surface 29<a> thereon disengages the claw and the trip 35 returns under spring action to the original position to release the clutch member 36 after one revolution. In an alternative construction the member 54 may be extended to form a handle device, so that it may be manually operated, whilst the " knock-down " tool is power operated, and the clutch device may be controlled by the operation of the same handle. Specifications 280,623 and 280,839, [both in Class 125 (iii)], also are referred to.

Title: Improvements in the lubrication systems of internal-combustion engines
IPC: F01M1/16
Filed: 1938-12-22
Abstract: 523,033. Forced - feed lubrication systems. BRISTOL AEROPLANE CO., Ltd., and OWNER, F. M. Dec. 22, 1938, No. 37337. [Class 12 (iii)] A spring-pressed release valve 28 normally limits the pressure at which a pump 15 supplies lubricating oil from a tank 17 to an internal combustion engine to say 801bs, per square inch but when the oil is cold a capsule 34 containing an expansible fluid and arranged in a chamber 33 connected to the fuel inlet conduit operates a piston valve 22 to allow the oil under pressure to pass by a conduit 38 to the top of the valve 28 and render it inoperative. As excessive pressure, say about 200 lbs. per square inch in the lubrication system is then prevented by a spring- pressed valve 40 connected to the inlet of the scavenge pump 16. Fig. 2 shows a preferred embodiment in which the capsule 34 operates the valve 22 in a ported sleeve 21 to connect a port 66 leading from the spring space of the normal pressure release valve 58 to the pump delivery chamber 45 when the engine is cold and to the capsule chamber 33 when the engine is hot. When the valve 58 is operated it opens ports 61 in a surrounding sleeve 59 to allow the oil to escape to the chamber 33. Passages 69, 70 in the valve 22 prevent the development of high pressure or vacuum on the left side of the valve 22. The capsule is preferably spring- biassed to its expanded position.

Title: Improvements in electronic pulse generating devices
IPC: H03K5/00
Filed: 1946-12-20
Abstract: 666,842. Pulse delaying circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 20, 1946 [Dec. 28, 1945], No. 37539/46. Class 40 (vi). A generator, fed with a series of marker pulses from an oscillator, is arranged to produce an output pulse, delayed from a triggering pulse by a whole number of marker pulses. In the system described, 25 c/s. triggering pulses are derived by employing a 100 kc/s. crystal oscillator to synchronize a pulse generator, the output being fed into a frequency dividing chain. The triggering pulse operates a flip-flop, which, upon restoration, generates a pulse. This pulse is used as a pedestal to raise a selected marker pulse from a suitable point in the divider chain sufficiently to operate a second flip-flop. The operation may be repeated to give a more accurately known delay to the final output pulse. Blocking oscillator 1, synchronized by 100 kc/s. crystal oscillator 2 feeds pulses to the cup and bucket circuit 17 to give a division of five. Further counter circuits 40, 42, 44, 46, 48, 50 in cascade, produce the 25 c/s. square wave 51, which, after differentiation appears as short pulses 70 at the cathode-coupled flip-flop 52. The positive-going short pulses operate the flip-flop to generate the output wave 71 which is differentiated by circuit 82 to feed the wave 72 to valve 86 of the mixer circuit 85. Pulses from counter circuit 44 are applied to valve 87, the output across the common load 92 appearing as in curve 73. Only when the pedestal due to the negative pulse of wave 72 is present, is the output amplitude sufficiently great to trigger a further flip-flop 100 to produce wave 74. After differentiation this wave is combined with marker pulses from circuit 40 of ten times the frequency of those from circuit 44, thus giving the second digit of the delay time. The process is repeated; the output from the final flip-flop 105 being utilized directly without selecting a pulse from the marker chain. The particular pulse from the chain selected by the flip-flops 52, 100 and 103 is controlled by the settings of the respective bias potentiometers 67.
