Patent GB-904165-A (GB)
Title: Improvements in means for the quantitative analysis of deuterium in hydrogenated compounds
Inventor: NIEF GUY
IPC: H01J49/02
Filed: 1959-08-27
Abstract: <PICT:0904165/III/1> <PICT:0904165/III/2> The proportion of deuterium in hydrogen-containing compounds is determined by vaporizing the compound to be tested, if necessary, reducing the vapour by passing over heated uranium and passing the so-formed hydrogen and deuterium to a mass spectrometer in which ions of atomic mass two (H2+) are separated from those of atomic mass three (HD+).  In the illustrated embodiment (see Fig. 1), a mass spectrometer tube 1 is attached via tube 2 to a pumping p  arrangement maintaining the desired vacuum in said spectrometer and via tube 3 to a gas line 5 (illustrated in detail in Fig. 2) in which the desired vacuum is maintained by pump 4.  The gas line 5 comprises a liquid nitrogen trap 21; a tap 22a by which the gas line can be isolated from the pump 4; a tap 22b controlling an inlet 25 for non-gaseous samples (e.g. a liquid such as water which can be introduced on a platinium helix 31 mounted on a plug 32, drawn to larger scale); a tap 22c controlling an inlet 26 for gaseous samples, e.g. hydrogen sulphide; a tap 22d whereby the introduced samples may be allowed to flow into an expansion bulb 23 and the uranium reduction section.  The latter consists of a silica U-tube 29 containing two very thin tapes, 28a, 28b of uranium, contained in an oven in which a temperature of 570 DEG -630 DEG C. may be maintained.  The reduction section is entered by means of a capillary tube 27 and the hydrogen and deuterium leave through capillary tube 30.  The taps, expansion chamber and capillary tubes may be heated by means of electric elements E, E1 to prevent condensation.  The sample after reduction to form deuterium and hydrogen passes into the spectrometer tube and the resultant separate ion streams of H2+ and HD+ are received by collectors 11 and 12 respectively.  The ion currents may be separately amplified (see Group XXXVI), compared and the result employed to determine the concentration of deuterium in the hydrogen.  The apparatus may first be calibrated by means of known mixtures of light and heavy water which also contain hydrogen sulphide.  In Fig. 1, the pumping system for the mass spectroscope comprises a primary pump 13 of the vane type in series with two mercury diffusion pumps 14 and 15, the former of which has an ejector.  A carbon dioxide trap 16 is also provided, and there is preferably a constriction between this and the pump 15.

Title: Controlling the movement of loads
IPC: G05D3/12
Filed: 1972-06-22
Abstract: 1434022 Controlling hoists EVERSHED POWER-OPTICS Ltd and THEATRE PROJECTS CONSULTANTS Ltd 18 June 1973 [22 June 1972] 29380/72 Heading B8B [Also in Division A6] A hoist drum 10 for lifting and lowering stage scenery is driven directly by a motor 16 and has a brake, the drum 10 being controlled by a closed loop servo system including a store 42a for data representing the power required by the motor 16 to hold the scenery load when the brake is removed, whereby the holding power of the motor can be applied before removal of the brake. In operation a control unit 40 receives signals from a motor driven tachogenerator 36 and potentiometer 38 representing actual load speed and position signals, and a preset signal from store 42a representing the torque required to balance the load. The signals from the unit 40 pass through a converter 44 to a comparator 46, which also receives from a store 42, signals representing the required position and speed of the load, and any resulting error signal from the comparator is applied over line 48 to an amplifier 32 controlling the drive of motor 16. When zero error is detected at 54, the brakes are applied and the system is switched off. Initially, when a new piece of scenery is placed on the hoist, a weight i.e. balance torque, signal must be derived and stored, and this is effected once the scenery has been hoisted to its required position indicated by a signal from store 42. When the hoist stops at the new position, there will be a difference between position signals 38 and 42 which difference represents the torque required to hold the load and an additional torque signal is then applied to the control unit 40 to counter the effect of the weight. The value of this additional signal is controlled by an error nulling control 52 until the error is reduced to zero. A zero error detector 54 then operates to enter the prevailing weight signal into the store 42a the output from the detector 54 also acts through a delay circuit 56 to actuate a brake applying unit 58 which operates a motor power off switch once the brake has been applied. The hoist may include a counterweight and may have alternative ropes, one of which passes round a motor driven pulley and the other of which can be pulled by hand with the motor disengaged. A group of several hoists may be operated from a single control unit.

Title: Magnetic pulse counting and forming circuits
IPC: H03K25/00
Filed: 1958-09-15
Abstract: 848,517. Circuits employing bi-stable magnetic elements. GENERAL TIME CORPORATION. Sept. 15, 1958 [Sept. 19, 1957], No. 29449/58. Class 40 (9). [Also in Group XIX] In a circuit which produces uniform output pulses in response to input pulses for the purpose of pulse-shaping, counting or integrating, a saturable magnetic core having a rectangular hysteresis characteristic is driven by the input pulses from negative saturation to a point beyond the positive saturation level, and the subsequent reduction in core flux, due to reversion to the positive remanent level in the interval preceding a further input pulse, initiates a resetting operation which reverts the core to its initial negative saturation state before this further pulse is received. For the purpose of pulse-shaping, the core flux is driven from negative to beyond positive saturation by a single input pulse, whereas the flux passes through a plurality of intermediate stable states if the circuit is used for counting or integrating a pulse train. As shown in Fig. 1, a saturable core 4 has a multi-tapped winding 9 between the taps 11 and 14 of which unidirectional input pulses are applied from terminal 1 by way of a transistor 7 operating as a rectifier. When the core is magnetized beyond saturation by an input pulse, the subsequent flux reversal when the pulse terminates induces a voltage in the winding sufficient to cause transistor 5 to conduct by rendering the collector and emitter circuit taps 11, 12 positive with respect to tap 13. A resetting current from a source 6 then passes from tap 11 to tap 12 and drives the core to negative saturation before the next input pulse is received. A plurality of taps 14 may be provided on the winding, the collector electrode of transistor 7 being selectively connected to one of the taps according to the input pulse count required. In a modification, Fig. 4, the transistor 18 in the input circuit is connected to the source 6 and to a separate core winding, and functions as an amplifier. A counting circuit is described, Fig. 5, in which an alternating current input to a transformer 21 is converted into unidirectional current pulses of the same frequency by a pulse-shaping circuit 22, these pulses being subsequently divided in frequency by 2 to 1 and 5 to 1 counting circuits 23, 24, each circuit comprising a saturable core and transistors as previously described. Constructional details are also disclosed, Fig. 6, in which a tape core 4 and the transistors 5 and 7 are separated by insulating disc spacers 28 and are housed with the associated resistors in an envelope 26, a multi-pin base 27 being provided for connection through a socket with the source 6 and other circuits.

Abstract: 462,842. Heat - storing apparatus. DETTMAR, G. Oct. 25, 1935, No. 29497. [Class 64 (ii)] Heat-storing apparatus applicable for the heating of rooms comprises storage bodies which may be solid or liquid, or may be fusible salts. Heat is supplied separately to each of a number of separated storage units, and is given up by the aggregate indirectly through an insulating covering or directly to a stream of air. When heat is stored at high temperature, each storage body,is separately heat-insulated. Combinations of storage bodies of different heat capacities and at different temperatures may be used. The storage bodies may have a large surface area to facilitate abstraction of heat. High temperature storage in fusible salt mixtures may be combined with low temperature storage in water. The low temperature storage bodies may receive heat from the high temperature storage bodies. Fig. 1 shows an example of a combination of separate heat storage bodies 1 in a casing 2. In Fig. 7, water in vessels 1 is heated by electrodes 3, the vessels being surrounded by a heat-insulating casing 2 having a door 5. The casing is open at the bottom and a tray 6 is provided to receive water if leakage occurs. The heating units of the separate storage bodies may be connected together in series or parallel, and some or all of the units may be used as required.
