Title: Improvements in or relating to electrical measuring circuit arrangements
IPC: G01N27/62
Filed: 1961-11-14
Abstract: 972,643. Peak current measurement; integrating current; gas analyzing apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 14, 1961 [Nov.17, 1960], No. 40707/61. Headings G1N, G1Q and G1U. An arrangement for measuring the separate time integrals of current peaks occurring in a circuit having a high resistance includes integrators, to one of which current is supplied during a current peak, and a device for measuring the voltage across the said one integrator. Each integrator consists of one of a series of capacitors which are switched in and out of the circuit successively by a means automatically operated by voltage pulses derived by the differentiation of signals related to the current peaks. The current peaks may be produced by varying the degree of ionisation of a hydrogen flame 3, in which is arranged an electrode 4 energized by a battery 5. One peak charges a condenser 9 through a resistor 6 so that the total amount of current passed in the peak is integrated by the condenser, which integrated value is measured in the device 7. A differentiated pulse is produced from this by a network 16, 17, amplified in the device 18 and used to operate the switch 13 to allow a subsequent current pulse to charge a further condenser 10. The battery 5 may be replaced by a charged large capacity condenser (Fig. 4 not shown). The arrangement may be applied in a method of determining gas compositions, wherein a gas mixture is passed through a chromatographic tube in which differential absorption takes place. This separates the constituents of the gas so that different constituents emerge from the tube at different times, and are passed into the flame 3 through the tube 1, so that its degree of ionisation varies according to the amount of the constituent present.

Title: Sealed secondary cells
Inventor: SCHOLZEL KARL
IPC: H01M10/34
Filed: 1967-09-11
Abstract: 1,201,244. Sealed accumulators. K. SCHÍLZEL. 11 Sept., 1967 [10 Sept., 1966], No. 41377/67. Heading H1B. A secondary cell of the kind tending to produce gas during overcharging and reversepolarity charging may be sealed if at the moment of sealing the positive electrode on the one hand contain a larger quantity of oxidizable material than the negative electrode contains of reduceable material and on the other hand contains a smaller quantity of reduceable material than the negative electrode contains of oxidizable material. The charge reverse on the positive electrode may be produced by overcharging the accumulator before sealing it in a hydrogen atmosphere. It may be increased by allowing the accumulator to stand in a reducing atmosphere before it is finally sealed still under a reducing atmosphere. Liberations of oxygen may be prevented and liberated hydrogen absorbed on reverse polarity charging by having a discharge reserve on the normally negative electrode. Alternatively the normally negative electrode may contain antipolar material, i.e. active material of the normally positive electrode which is in its unoxidized state prior to reverse-polarity charging but on reverse polarity charging absorbs oxygen immediately it is formed becoming partially oxidized in the process. This partially oxidized material may then absorb hydrogen evolved at the positive electrode. The positive electrode may also contain some antipolar material. In one embodiment a nickel-cadmium accumulator, Fig. 6b, has a rectangular metal case 16 sealed by plastics cover 17 fitted with resealable safety valve 26. Electrodes 18, 19 are separated by porous elements 20 saturated with electrolyte thickened with silica gel. Electrodes are joined to opposite ends of the case by wires 21, 22. In another embodiment a Ni/Cd cell, Fig. 7b, has a metal cylindrical case 16<SP>1</SP> sealed by metal lid 17<SP>1</SP> insulated from it by ring 27. Positive electrode 18<SP>1</SP> may be Ni(OH) 2  and negative electrode a mixture of Cd, Cd(OH) 2  and as antipolar material, Ni(OH) 2 . The electrodes are spiral and are separated by spiral element 20<SP>1</SP> saturated with aq. KOH solution. Both electrodes as insulated from the container bottom by disc 28, one being connected to the lid by wire 25<SP>1</SP> and the other being in contact with the container wall. Vent 30 is used during initial overcharging of the cell but is sealed with resin before it is used.

Title: A forced-flow, once-through boiler and turbine installation
IPC: F01K3/26
Filed: 1960-12-01
Abstract: 920,849. Steam turbine plant. SIEMENSSCHUCKERTWERKE A.G. Dec. 1, 1960 [Dec. 1, 1959], No. 41431/60. Addition to 889,076. Class 110 (3). The present invention relates to an improvement in the plant described and claimed in the parent Specification in which a forced flow once through boiler having a reheater supplies a single turbine having at least a high and a low pressure stage, there being a water-containing vessel which is included in the feed water system connected to the outlet of the high pressure stage such that some or all of the steam passes into and through the boiler feed water in the vessel and gives up some of its heat, this steam and the additional steam generated in the vessel being conveyed to the reheater in which it is reheated before being conveyed to the low pressure stage. According to the present invention, a proportional pressure control is provided which permits the live steam pressure and the pressure in the intermediate pressure section to vary in accordance with the load, whilst maintaining a fixed ratio between these pressures. The turbine has a high pressure stage 1 and a low pressure stage 2 coupled to an electric generator 3. Steam from the low pressure stage is condensed in a condenser 4 and the condensate delivered by a pump 5 through a pre-heating installation 6 to a feedwater container 7. A further pump 8 delivers the working medium through high pressure bled steam feed water heaters 17, 18 to the water containing vessel 9 having a sufficiently large water chamber for it to be used as a heat storage means. Steam from the outlet of the highpressure turbine stage 1 passes through the water in the vessel 9 and gives up its superheat and produces additional steam. The newly produced steam flows with the cooled steam through the reheater 15 to the low pressure turbine stage 2. A reducing valve 16 is provided in a conduit connecting the live steam pipe to the vessel 9. The high pressure inlet valve 19 is controlled by a controller 20 in response to the pressures in the live steam and intermediate steam pipes so that these pressures are maintained in the same ratio. A speed governor 25 controls the low pressure stage 2. The boiler 11 is also controlled by the live steam pressure or intermediate pressure.

Abstract: 977,881. Filters. BUELL Ltd. Oct. 29, 1963 [Nov. 6, 1962], No. 41950/62. Heading B1T. A dust collector for cleaning dust-laden gases comprises a battery of filter tubes 5 within a casing 1 which has an inlet 12 for the dust-laden gas allowing it to pass to and inwards through the walls of the filter tubes 5, each of which has one end connected to a support plate 4 provided with a series of ports, one communicating with the interior of each tube 5 to form outlets for the cleaned gas, and a rotary arm 15 which has a gas supply opening connected to a gas supply duct 16 and which sweeps round the support plate 4 so that the opening registers with each port in turn, the duct 16 being supplied with a gas at a pulsating pressure so that as the arm 15 rotates, gas is periodically blown back through the tubes 5 in turn to remove dust which has collected on the outside of the tubes, the tubes being agitated by the pulsating pressure to facilitate the dust removal. The tubes 5 may be of canvas and be stiffened by circumferential stiffening rings 9 at intervals along their length, being held straight by weights 10 at their bottom ends. Preferably, the frequency of the pulsations in the gas supply pressure through the pipe 16 is equal or nearly so to the natural resonant frequency of the gas columns in the tubes 5. A fan 14 in the roof of the casing 1 draws the dust-laden gas through the tubes 5 and the clean gas through an outlet duct 13.

Abstract: 1366912 Fuel injection pumps ROBERT BOSCH GmbH 9 Sept 1971 [10 Sept 1970] 42060/71 Heading F1A In a fuel injection pump for an I.C. engine and of the type in which an auxiliary pump piston 15 operating in synchronism with the injection piston 3 is connected to operate a by-pass valve 12 against the action of a spring 26, the return flow of operating liquid from the valve 12 being controlled by an adjustable throttle 23 to provide a hydraulic lock at a speed dependent on the throttle position, the throttle 23 is adjustable by rotation of a valve spool 24 and when the engine is stopped the spool moves axially to a position preventing flow through the throttle. With the engine stopped a spring 34 urges the valve spool 24 to a position blocking a passage 22 leading to the throttle 23. Thus starting of the engine is prevented since the by-pass valve 12 cannot close.  On operation of the engine's ignition switch an electromagnet 48 moves the spool 24 to the operating position shown. During operation adjustment of the throttle 23 is effected by rotation of an accelerator controlled member 33 having a pin 32 engaged in a slot 31 in the spool valve 24. At start up a valve 37 by-passes the throttle 23 until a feed pump 43 builds up sufficient pressure in a chamber 40 to overcome a spring 39.
