Title: Improvements relating to sensing when viscosity of a fluid has risen to a given level
IPC: G01N11/00
Filed: 1969-06-16
Abstract: 1,235,589. Testing viscosity. BAXTER LABORATORIES Inc. June 16, 1969 [June 17, 1968], No. 30360/69. Heading G1S. [Also in Division G4] In order to measure the time taken for the viscosity of a sample Fig. 1 to rise to a predetermined level after a reagent is added, a spherical ball 18 is magnetically 14, 16 suspended in the sample, the sample is reciprocated 12 in a vertical direction, and constant frequency clock-pulses are counted from the instant of adding the reagent until the viscosity has risen to the predetermined level, this being detected photo-electrically 20, 22 (or by inductive means, not described). As described the sample is blood to which thromboplastin has already been added, and the reagent is calcium chloride. In operation the sample, containing the ball, is placed in a well 40, Fig.2, of atemperature controlled block 30. The ball then rises to the level of the magnet 14, 16 and blocks the light path 20, 22, Figs.2, 6, thereby energizing a relay K1 (shown de-energized) to start a reciprocating drive motor 44 and a 10c/s clock-pulse generator motor 108 details Fig. 5 (not shown). Addition of a measured quantity of reagent is effected by depressing a cylinder 54, Fig.2, to thereby close a switch 66, Figs.2, 6, and energize a second relay K2, which holds over its lower contact and allows clock-pulses to pass over its upper contacts to a counter 250. Eventually, when the viscosity has risen, the ball is dragged from its position between the magnets 14, 16, the light path 20, 22 is cleared, and relay K1 is de-energized to break the hold circuit for relay K2 and the counting is stopped. Dimensions and components of a preferred embodiment are given in the Specification.

Abstract: 601,197. Furnaces. STORDY ENGINEERING, Ltd., and STORDY, J. J. Nov. 15, 1945, No. 30539. [Class 51(i)] In a kiln for revivifying bone charcoal and the like comprising vertical tubes 12, which may be provided with internal or external fins or both, between which the heating gases are circulated and through which the charcoal gravitates from a hopper 10 to cooling-tubes 16, uniformity of heating is attained by recirculation of the combustion products. The combustion chamber 22 is fired by a gas-burner, a fan 25 extracting the gases from the opening 24 and passing them to a chamber 27 communicating by passages 28 with the chamber 29 containing the tubes 12. The bulk of the gases return to the combustion chamber 22 through passages 30, but sufficient bleeding is effected through the pipe 31 to allow gas and air for combustion to enter the chamber 22. Pipes 32, connected to discharge pipes 33, collect steam and vapour from the charcoal in the tubes. The cooling tubes 16 are provided internally and externally with pipes 17, 19 open at their lower ends for the admission of cooling-air and connected at their upper ends to headers 20 connected to exhausting- means.

Title: Improvements in or relating to Oscillators
Inventor: COPELAND JOHN ALEXANDER III
IPC: A23C9/00
Filed: 1967-07-05
Abstract: 1,190,984. Semi-conductor oscillator circuits. WESTERN ELECTRIC CO. Inc. 5 July, 1967 [11 July, 1966], No. 30936/67. Heading H3T. [Also in Division H1] An oscillator consists of a diode 11 exhibiting a bulk negative resistance effect in combination with circuitry such that during oscillation the electric field in the diode alternates between positive and negative resistance regions of the diode characteristics (Figs. 2 and 2A, not shown). The conditions of oscillation are such that, in each cycle of the oscillation, the period for which the diode is in its negative resistance state is sufficient for there to be a net gain during the cycle but insufficient for a high-field domain effect to be produced. As shown this is achieved by energizing the diode from a D.C. source 12 which sets up in the diode 11 a field which may be below but is preferably above the negative-resistance-producing threshold field, and using an L-C circuit 14 to cause the field to fluctuate above and below this value at a frequency determined by the value of L and C. The oscillator frequency is the L-C circuit natural frequency, and oscillations will be selfsustaining provided that the required conditions as to the relative lengths of time that the field is above and below the threshold field are observed. The Specification discusses these conditions and discloses formulµ by which a circuit fulfilling these conditions may be designed.

Filed: 1919-12-10
Abstract: 160,233. Wegner, G. A. Dec. 10, 1019. Fluid-actuated valves.-The discharge from the evaporator coil 5, Fig. 1, of a compression refrigerating machine is controlled by a thermostatic valve 23 subject to the temperature of the gas at the discharge end of the coil. The closing of this valve creates a pressure within the coil to close a pressure - actuated valve 7 controlling the supply of liquefied gas to the coil, the arrangement serving to prevent the passage of saturated or unevaporated refrigerant to the compressor. A suitable pressure-actuated valve 10 is shown in Fig. 5. The inlet valve is pressed to its seat by a spring 11 located within a piston 12, but is normally maintained in an open by a spring 20 acting through a diaphragm 16 and plates 19, 17. The spring 20 is adjustable by means of a screw 21 and is set to give a particular pressure within the evaporator.

Abstract: Needle-shaped crystals of dibenzylethylene-diamine diphenoxy methyl penicillin having at least 50 per cent of the crystals of length greater than two microns is obtained by precipitating the crystals from an aqueous solution thereof in the presence of an aliphatic alcohol or ketone.  Specified are methanol, ethanol, isopropanol, butanol, acetone, methyl ethyl ketone and mixtures thereof.

It is preferred to heat the solutions above room temperature, e.g. up to 50 DEG  C., especially 45 DEG  C., prior to mixing, and to add the solution of dibenzylethylene diamine salt (1) slowly (10 to 15 minutes) with agitation to the solution of the penicillin salt, (2) the temperature being maintained at e.g. 45 DEG  C.  Alternatively, solutions (1) and (2) may be run slowly (2 hours) into a mixture of the alcohol or ketone and water, the penicillin salt being in excess until the end of the addition. The penicillin salt may be used orally (see Group VI).ALSO:Crystalline dibenzylethylenediamine diphenoxymethyl penicillin having at least 50 per cent of the crystals of length greater than two microns (see Group IV (b)) is employed in aqueous suspensions for oral use.
