Title: Improvements in or relating to electric measuring instruments
Inventor: YOUNG REGINALD SEARLES
IPC: G01N27/02
Filed: 1955-02-22
Abstract: 833,203. Impedance measurements. BRITISH ALUMINIUM CO. Ltd. Feb. 22, 1956 [Feb. 22, 1955], No. 5353/55. Class 37. [Also in Group XL (c)] In a device for determining the conductivity of a metal, a timed anode-tuned grid oscillator provided with a D.C. negative feed-back between the oscillator and the negative pole of the H.T. supply is controlled by the material under test which is associated with the grid inductance and feeds a detector stage which incorporates a meter responsive to the current passed by the stage. The sensing head, Fig. 2, comprises a dust core assembly 5 of rotated " E " section on the control core of which is wound coil L2. This assembly is mounted in a bore 3 in housing 4 and is provided with a cap 8. An enlarged bore 6 with cap 8 provides a shoulder 7 through which are three holes provided with spring-loaded balls 9 on which the housing rests. Compression spring 12 holds the individual springs 11 in position. The investigating head is connected to the measuring circuit by a coaxial cable 13 the outer conductor of which is connected to the chassis of the instrument and to spring 12 while the inner is connected to coil L2 at one end and capacitor C7 (Fig. 1) at the other. The other end of the inductor is connected to spring 12. Circuit (Fig. 1). The oscillator comprises a pentode V1 with tuned anode and tuned grid. Coil L2 in the measuring head is connected in parallel with capacitors C4, C5 and forms the tuned grid circuit. Coil L1 in the anode circuit is shunted by a finer capacitor C1 and variable capacitors C2, C3. Feed-back from the anode of V1 is through a variable capacitor C6 to the junction of C4, C5. The oscillator output feeds a detector stage comprising pentode V2 with microammeter M in its anode circuit. The heaters of V1, V2 are connected to the negative line when 5 is closed, through negative feedback resistor R4 by-passed by capacitor C11. Detector V2 is arranged to be non-conducting when the oscillator is not oscillating. The effect of the feed-back resistor is to provide a standing bias for the oscillator and, when V2 conducts to provide increased feed-back to limit the amplitude of oscillations and stabilize the oscillator.

Abstract: 1,221,501. Accelerator for track toy. MATTEL Inc. 31 Jan., 1969 [13 Aug., 1968], No. 5367/69. Heading A6S. A vehicle propulsion means for accelerating an unpowered toy vehicle along a predetermined path of travel comprises mechanical gripping members adapted for engaging and disengaging the vehicle on opposite sides thereof with substantially equal force and means for moving said gripping members at substantially the same speed and acceleration. As may be seen from Fig. 3, a cocking lever 31 is manually pulled into the position shown against the force of a spring 65 and a toy vehicle (not shown) on the roadway 13 moves the trip wire 33 causing the two gripping members 25 and 27 to engage and grip with equal force opposite sides of the vehicle and immediately move in the direction of vehicle travel to thereby accelerate the vehicle along the roadway. The track is preferably banked at each end to prevent the toy vehicles leaving the track. In an alternative embodiment shown in Fig. 8 the vehicle propulsion means comprises counter-rotating resilient tyres 263 and 263' (driven by the motor 221 through engagement of its drive gear 223 with one of the drum gears 259). Additional peripheral gear driven drums may be arranged so that one additional parallel track section and two further track sections at a lower level and at an angle to the first pair of track sections together make up a double flyover (see Fig. 10, not shown).

Title: Improvements in bacteriological digesters for conversion of organic waste
Inventor: ABSON JAMES WILLIAM
IPC: C05F17/02
Filed: 1963-02-12
Abstract: In the downward passage of refuse in countercurrent to air through a plurality of composting stages with water-spraying in each stage, the temperature and carbon dioxide content of the effluent gas is continuously measured and automatically controlled by sensing means and connected valves which are capable of effecting variation in the rate of air and water flow.  The water may be in the form of ammoniacal liquor or sewage sludge.  Refuse may pass through five successive circular chambers (3) in a tower (1) from an inlet (6) to an outlet (7) via offset openings (8), partly composted refuse being recycled from the third to the first chamber via a worm conveyer (24).  Water is sprayed into the chambers from pipes (9) connected to a manifold pipe (10) controlled by a valve (11). Air is passed successively into each chamber via an annular passage (17), the interior of a hollow rotary arm (5) connected to a shaft (4), and orifices (18), the air being supplied to the lowest chamber through a pipe (15) and valve (14). The valves are connected to sensing devices (20 and 21), for respective measurement and control of temperature and carbon dioxide content, which are situated in a gas outlet (19). The whole apparatus may be enclosed in a heat-insulating sheath having outlet openings for gas at its lower end.

Title: Improvements in and relating to the manufacture of infra-red sensitive materials foruse in photo-electric cells
Inventor: ROTHSCHILD SIEGFRIED
IPC: C23C14/00
Filed: 1957-02-20
Abstract: One method of producing lead sulphide and two methods of producing lead oxysulphate are described.  Lead sulphide is produced by adding concentrated ammonia solution to a solution of thiourea in water, then adding an aqueous solution of lead acetate and boiling the whole for about 15 minutes.  The precipitate so produced is filtered off, washed with distilled water, industrial spirit and finally with acetone and then dried in vacuo at about 85 DEG  C.  The dried precipitate is then heated to about 400 DEG  C. for 45 minutes in an atmosphere of nitrogen which has been previously dried by passage through a tower filled with activated alumina. Lead oxysulphate may be produced by mixing solutions of lead nitrate and ammonium sulphated, evaporating to dryness by heating with infra-red radiation and heating the ground dry product to about 600 DEG  C. for 30 minutes in an atmosphere of air. Alternatively lead oxysulphate may be produced by pouring a turbid aqueous solution of (CH3COO)2Pb.Pb(CH)2 into a warm solution of (Na2SO4.10H2O), allowing to stand and then filtering off the precipitate, washing it and drying it at 100 DEG  C.
