A second set of electrodes can be placed above the plate 11 and the whole subjected to pressure by a screw 13. The battery is provided with end plates 2 of paper pulp &c. Cement is poured into the mould to fill the spaces 15 between the electrodes and frames and the sides of the mould. Fig. 1 shows one of the end plates 2 which is provided with tongues 3 to locate the superposed plate 5, and projections 4 to space the plate from the walls of the mould. The frames 6, shown in Figs. 2 and 3, are also provided with tongues and projections 8, 7 and they may carry members 10 projecting into the space enclosed by the frame as shown in Fig. 4 to prevent contact between adjacent electrodes; this may also be effected by a. linen covering on one of the adjacent electrodes.

In the testing of the contents of liquid-filled containers 12 (e.g. milk bottles) for contamination by foreign bodies (e.g. chips of glass), the containers are fed to a detecting station where one or more transducer devices are disposable to create waves in the contents, an oscillator 1 is in the electric circuit of that transducer device which imparts vibrations to the contents, an indicating and/or container-rejection device 9 is energized by the transducer device which receives waves after traversing the contents, and a gate device is in circuit with the indicating and/or rejection device and is operable out of phase with the impulses from the receiving transducer device whereby only impulses from waves in a contaminated container are passed to the indicating and/or rejection device. The vibrations are preferably in the frequency range 1 kc. to 10 Mc/s. In one embodiment impulses are fed by means of a trigger device 7 to transmit/receive transducer 14 and the trigger pulses are fed via a delay device 8 to gates 5 and 16, the output of the latter when present actuating rejector 9. Limiters 17, 18 are included, their limiting levels being set respectively at levels corresponding to weak and strong, e.g. from the bottom of the bottle) reflections. The operation of the embodiment, with various combinations of the normal states of gates 2 and 5, is described in detail; for one combination the trigger device 7 is connected directly to gate 5 to deliver blanking pulses thereto during movement of bottles to and from the testing station. In another embodiment (the Figure of Provisional Specification 36479/60, not shown) separate transmitting and receiving transducers are utilized and items 16 ... 19 are omitted. Valve gating circuits, Fig. 2.-The gate formed by triode valve 21 is closed by a pulse applied to terminal 29: cold-cathode trigger tube 30 conducts thereby placing a high negative bias on the grid of the triode. A pulse applied to terminal 36 causes tube 30 to extinguish and the gate opens.

Abstract: 792,022. Wave meters. MARCONI INSTRUMENTS, Ltd. Aug. 16, 1956 [Dec. 21, 1955], No. 36642/55. Class 37. A heterodyne wave meter consists of two ganged variable oscillators 1 and 2 with means independent of the ganged control for varying oscillator 1 over a small range, a calibrating source 16 and 17 for producing a series of standard frequencies, a mixer 11 and means for detecting the presence of and counting heterodyne beats. To measure the frequency of the signal received at 19, switch 10 is placed to 20 and switch 8 connects up oscillator 2 and dial 4 is adjusted for zero beat in the headphones. Switch 10 is then placed to 18 to connect up the calibrating source in place of 19 and 4 is again adjusted to the nearest frequency below to again produce zero beat. Finally, oscillator 1 is made to replace oscillator 2 with 19 connected up, control 6 is adjusted to produce zero beat. Switch 10 is then placed to 9, switch 7 is opened and switch 8 is closed and the resultant beat between the oscillations from 1 and 2 is counted by 14 and indicated by 15. This indication added to the frequency to which oscillator 2 was set when in comparison with 16 is an indication of the frequency. An absorption wave meter 21 may also be ganged to I and 2 in order to give a rough indication and hence remove ambiguity. The calibrating source may comprise a crystal-controlled oscillator 16 and a decade divider 17.

Title: Greenhouse control system

Filed: 1976-09-09
Abstract: 1511639 Temperature control S OKUHARA 9 Sept 1976 [12 Sept 1975 3 March 1976] 37416/76 Heading G3R A motor or motors for opening and closing of a ventilation window or windows of a greenhouse are controlled in dependence on the greenhouse interior temperature. In general, there will be a  motor for each window, but operation of a plurality of windows by a single motor is not precluded. In Fig. 1, each of the motors M1 to Mn is controlled by a corresponding unit B1 to Bn, in response to three inputs representing respectively the greenhouse temperature at 2, a reference temperature pre-set in respective units A1 to An and a signal derived from respective potentiometers P1 to Pn whose setting is varied either by the windows Gl to Gn or by the shafts of the associated motors M1 to Mn. These input signals are so combined as to cause the window opening to diminish as the temperature rises. The circuitry Figs. 2 to 5 (not shown), is such that the motors cannot be moved beyond the positions in which the windows are fully open or fully closed. If the temperature continues to fall once the windows are fully closed, a heating system 7 is switched on. If the external wind speed exceeds a selected "strong wind" value, the automatic control is over-ridden by units 5 and 6 which effect closure of all the windows. Provision is also made for a manually-operated override. The automatic control may be such as to provide a "dead" temperature zone within which the windows remain closed (or open) until a certain threshold value of temperature error has been exceeded. The temperature-sensing means 2 consists of a temperature-sensitive silicon diode connected in a bridge circuit.

Abstract: 1399638 Thermonuclear fusion KMS FUSION Inc 11 Aug 1972 37509/72 Heading G6P  In the production of energy from thermonuclear fusion, a quantity of fuel is irradiated by laser flux of increasing magnitude so as to cause a succession of compression shock waves to be transmitted into the fuel to cause an implosion such as to ignite the fuel into a plasma. The fuel, which may be in the form of a solid or hollow sphere of deuterium-tritium, is subjected to the radiation from a number of lasers arranged to produce a convergent beam which is directed on to the fuel by mirrors. The latter are protected from charged particle flux magnetically. The increase in laser flux is effected non-linearly so as to cause all shock fronts to each the implosion centre simultaneously. The thermal energy output, which is removed by means of a liquid lithium coolant, results from the kinetic energy of the expanding plasma and charged particle reaction products, and from moderation of 14 MeV neutrons from the D-T reaction. The fast neutrons can be moderated and multiplied in beryllium and the resulting neutrons trapped in lithium to produce tritium, thus operating in a breeder configuration.
