Title: Apparatus for applying a load to a workpiece
IPC: G01N3/36
Filed: 1970-04-07
Abstract: 1312301 Load applying apparatus DEFENCE SECRETARY OF STATE FOR 7 April 1970 16533/70 Heading G1S [Also in Division F1] An apparatus for applying a cyclically varying load to a workpiece comprises a first 38 and a second 74 supply of fluid, the first, at a higher pressure than the second, being connected via a regulator to a piston and cylinder 12, 10 there being means for connecting a workpiece 16 to the piston and to a fixed object and further comprising fluid logic amplifying means operated by the second fluid supply to produce a signal to control the fluid regulating means whereby fluid from the first fluid supply is selectively fed to the cylinder to cause movement of the piston and hence loading of the piston. The sample 16 is connected to piston 14 and spring dynamometer 19 by rods 14, 18 respectively. Piston 14 is moved by means of high-pressure air applied alternately to surfaces 26, 28 of the piston through valves 34, 36 respectively from a source 38. The opening and closing of valves 34, 36 is controlled by a fluid logic circuit including turbulence amplifiers 48, 50, limit switches 66, 72 operated by projection 80 on rod 18 and lowpressure air source 78. Each turbulence amplifier directs air from its input 56, 58 to its output 44, 46 (ON condition), unless air is supplied through any of the control inputs 62, 64, 68, 70, when the amplifier provides no output, (OFF condition). In operation, initially in the position shown neither limit switch passes air and amplifier 48 (say) is ON. Low-pressure air passes to valve 34 to open the valve admitting H.P. air to the cylinder 10, moving the piston downwards. Low-pressure air from amplifier 48 also passes to amplifier 50 maintaining this amplifier OFF, so that no low-pressure air passes to either input 62 or valve 36. When the piston 12 has moved downwards sufficiently for projection 80 to contact limit switch 66, lowpressure air passes to control input 64 of amplifier 48, switching it OFF. No air passes from the output 44 to amplifier 50 so this amplifier is switched ON, or to valve 34 which is switched OFF. Lowpressure air passing through amplifier 50 passes to input 62 of amplifier 48, holding it OFF, and to valve 36 which is switched ON and passes highpressure air from source 38 to the lower side of piston 12, to raise the piston. When projection reaches the upper limit switch 72, the cycle is repeated after switch 72 sends a pulse of low-pressure air to switch amplifier 50 OFF. The oscillations of the piston are counted by means of a counter 39 counting pulses from valve 34; when the sample 16 fractures the logic circuit will cease to operate and the number of pulses may be read.

Abstract: 1318365 Position finding RHEINMETALL GmbH 7 Sept 1970 42783/70 Heading G4H [Also in Division H4] An apparatus for detecting the point at which a projectile passes through a two dimensional grid comprising two banks of light sources 12, 14 (Fig. 1a) and two banks of light receivers 20, 22, each light receiver is associated with a store 24, 26 which is set when the light to the associated receiver is cut off by a projectile, the stores then being sequentially scanned to determine the set store in each dimension. As described a shot detector 28 detecting a projectile enables, after a time delay, a pulse generator 32 which simultaneously transmits pulses to a counter 54 (Fig. 1b) in an indicator and steps a counter 34 associated with one direction to interrogate the stores 24. When a set store is detected the generator is stopped to stop the count. The process is then repeated for the other direction, the resulting counts being displayed on number tubes. The indicator may simultaneously display the results of several shots. The co-ordinates may be printed. The speed of the projectile may be found by measuring the duration for which the light source is interrupted. The frame supporting the light transmitter may be provided with a heat reflective coating to minimize errors due to temperature variations. Each light receiver is connected via a high pass filter to its associated store so that stores are not set when slow moving objects, e.g. birds, interrupt the light. Corrections for large calibre shot may be made.

Abstract: 1327197 Production of silica fibrils IMPERIAL CHEMICAL INDUSTRIES Ltd 6 Oct 1970 [27 Oct 1969] 52446/69 Heading C1A Silica fibrils are produced by treating a fibrous mineral silicate in suspension in a liquid medium with an agent which removes at least part of the metallic oxide constituent of the fibrous mineral silicate. The fibrils are elongated particles having an axial ratio of at least 10 : 1 and having a width not greater than 0À1 micron. Generally fibrils of 10 to 100 microns in length are produced. It is convenient to make the suspension of fibrous mineral silicate e.g. chrysotile asbestos, attapulgite clay and sepiolite clay, by mechanical and/or with the aid of ultrasonic radiation in a suitable liquid e.g. water. Advantageously a surface-active agent e.g. dodecyl benzene sodium sulphonate and dioctyl esters of sodium sulphosuccinic acid is included preferably at a concentration of 0À1 to 5% by weight of total weight of silicate dispersion. Preferably the agent used to dissolve out the metallic oxide is an acid at a concentration up to 5 molar e.g. hydrochloric, sulphuric, nitric or acetic acids or with acid salts. The treatment, preferably with stirring, is carried out from 20 C. to the B.Pt. of the suspension for generally from 5 minutes to 48 hours. The product of the treatment process is filtered and washed with water to remove soluble inpurities and residual surface-active agent. In cases where water-insoluble surface-active agents are used, washing with a solvent for the surfaceactive agent e.g. methanol or acetone is convenient. The fibril product may then be dispersed in an aqueous medium or in a polar organic liquid or just dried.

Microwave source 9 provides energy via directional coupler 11 to aerial 14 which also receives reflected signals and passes them via ferrite modulator 16 to aerial 19 which picks up the twice reflected signal and passes a portion thereof via coupler 17 to detector 22. The modulator 16 phase shift is continuously varied by oscillator 24 and at resonance logic 23 passes the instantaneous voltage thereof to indicator 26 calibrated in thickness. In a second embodiment (Fig. 3, not shown) a variable frequency source provides energy to a four-port circulator which directs energy to a first aerial, directs reflected energy to a second aerial and directs the twice reflected energy back to the first aerial. Part of the twice reflected energy is coupled to a detector which detects resonance and indicates the thickness from the resonant frequency. In a third embodiment an oscillating feedback circuit is produced using a travelling wave tube amplifier. The resonant frequency of the circuit determines the thickness of the material (Fig. 4, not shown).
