Title: Projectile fuse
IPC: F42C13/04
Filed: 1971-05-11
Abstract: 1342507 Fuzes GENERAL ELECTRIC CO 11 May 1971 [11 May 1970] 14146/71 Heading F3A A projectile fuze which can be remotely set to function either as a proximity and selfdestruction fuze or as an electronic time fuze, and is also resistant to electronic counter measures, comprises an antenna 12 for receiving command pulses from a remote source, a local oscillator 50 which commences when the projectile carrying the fuze is fired, and a counter 10 for counting the pulses from the remote source and local oscillator. When the fuze is to function as a proximity and self-destruction fuze, the counter is filled to the point T 1  and, after a pause determined by delay 66, an inhibit latch 72 is de-activated and an oscillator 76 supplies pulses to a proximity transmitting antenna 80. Meanwhile pulses from the local oscillator 50 activate a latch 62 so as to prevent the fuze from receiving pulses from electronic jamming devices. Loading of the oscillator 76 by the proximity of a target is detected by a monitor 86 which supplies a signal to a circuit 44 for firing a detonator. However, if a target is not detected within one second, the counter, which has now been advanced to the point T 2  by the local oscillator, triggers a multi-vibrator 92 and this causes the latch 72 to block the oscillator 76. Self-destruction occurs some time later when the counter has been advanced to the point T 3  by the local oscillator. When the fuze is to function as an electronic time fuze, the command pulses are fed to the counter at such a rate that the signal from the point T 2  is received by the latch 72 before the signal from the point T 1  passes through the delay 66. The oscillator 76 therefore never becomes operative and the fuze is detonated when the counter is filled up to the point T 3  by the local oscillator 50. The power for the fuze is supplied from a thermal battery or a piezo-electric device.

Cladding sheets A, made of metal and produced e.g. by pressing, are permanently bowed during manufacture to resist any tendency to buckle, or bow outwardly when they are secured to a roof, or wall, framework. To secure a panel to a framework one side edge is first attached by means of a cover strip 1 having an interior T head 2 to receive a fixing bolt 3 as described in the parent Specification, the bolt 3 passing through a hole in a junction strip S and being anchored to a purlin P by a fixing strip 4. An insulation panel 7, when incorporated, is first fixed by means of spring clips 8, 8<SP>1</SP> between the corresponding adjacent junction strips S, whereupon the other projecting side edge of the panel is pulled down and secured in position by means of the next cover strip, the first edge of the next cladding sheet being hooked beneath it before it is pulled tight. When sheets are fitted one above the other the upper sheet can be prevented from sliding down by cutting diagonally into the edge of the lower sheet and bending the resultant triangle outwardly to engage the bottom edge of the sheet above it. The bowing of the sheets may be obtained by a brake pressing operation subsequent to the main profile pressing. Alternatively each sheet may be set by hand. Specifications 699,054 and 699,055 also are referred to.

Title: Production of pure preparations of the kallikrein inactivator
IPC: A61K38/57
Filed: 1964-04-08
Abstract: Impure solutions of kallikrein inactivator are purified by treating the impure solution with an aqueous solution of a water-soluble salt of metaphosphoric acid whereby the sparingly soluble complex of the inactivator and salt is precipitated, an excess of the metaphosphate salt being avoided, then separating the precipitated complex and freeing it from the salt to give purified solution.  Preferred soluble salts are metaphosphates of ammonium or alkali metals, and by avoidance of excess is meant that the aqueous salt solution is added only until no further precipitation occurs.  The complex may be freed from the salt by dissolution in a solution containing more than 1% w/v concentration of a salt such as ammonium or sodium chloride or ammonium or alkali metal hydroxide, to decompose it, followed by removal of salts by e.g. dialysis or ion exchange; the pure solution may be lyophilized.  Impure solutions for starting materials are suitable preparations from kallikrein-inactivator-containing animal organs, e.g. paratid or lymph glands, lungs, liver, spleen, or pancreas.

Title: An automatically operated valve to control the flow of air or gas
IPC: F23L13/02
Filed: 1934-05-16
Abstract: 438,428. Fluid - actuated valves. HARTLEY, T. W., The Old House, Seisdon, Wolverhampton and TINLEY, E. L., Three Gables, Spring Hill Park, Lower Penn, near Wolverhampton. May 16, 1934, Nos. 14727/34 and 4213/35. [Class 135] In a valve which is actuated by outlet pressure beneath a liquid-sealed bell 27 in such a way that it is opened when the resistance at a point on the delivery side of the valve increases and is closed when such resistance decreases, the skirt of the bell is disposed between two cylindrical overlapping walls 32, 33 extending from the bottom and top of a closed chamber 21 respectively. The valve is particularly applicable to the control of the air flow from a fan 43 to a furnace 44. The increased resistance offered to the air flow by the fire bed 45 due, say, to stoking causes an increased pressure in the conduit 13 and this causes the valve to open, a decreasing resistance having a reverse effect. The butterfly valve 10 is connected by a rod 18 to the bell 27 exposed to the static pressure in the conduit 13 by means of a pipe 24 closed by a plug 25 and having perforations 26. Alternatively the end of the pipe may face the fluid flow so that the full delivery pressure is used. The chamber 21, which has a removable cap 29 is secured to the valve casing 11. A dip stick 42 is provided in the space 41. This space has a manually adjustable air-venting valve. The valve is biassed towards the open position by the adjustable spring 55. When the fan is stopped, the valve reverts to the position shown in Fig. 1, but sufficient air flows between the edges of the valve and its casing to maintain a small fire. The spring 55 is arranged outside the casing 11 and is connected to the free end of a camfaced arm 48 on the valve shaft by a flexible link 54. By this arrangement the leverage is changed progressively as the valve opens in accordance with the pressure changes in the conduit 13. The arm 48 may be replaced by a straight arm carrying an adjustable weight, and having adjustable stops to limit its rotary movement.
