IPC: B29C37/00
Filed: 1980-02-11
Abstract: For cylindrical sodium sulphur cell, a cathode electrode structure is provided with improved electronic conductivity in the radial direction, compared with other directions, by forming a block of fibre material, e.g. graphite fibres, with thefibres aligned in one direction (arrow A), slicing the block to form a sheet7 with fibres normal to the plane of the sheet, moulding the sheet 7 and impregnating it with cathodic reactant in a heated mould having a plurality of ribs, to form a plurality of trapezoidal segments with the fibres normal to the planes of the parallel surfaces of the trapezoids, cooling the mould so that the impregnant is solidified and then forming the trapezoids into an annular structure. Preferably the mould is such that thin webs are left joining adjacent trapezoidal sections along parallel edges of the wider ofthetwo parallel faces so that the webs form hinges forfolding the segments into the annular assembly.

Abstract: Oral hygiene methods and apparatus for producing a liquid jet by pumping liquid through an inlet (122) in a pump housing (23) from a reservoir (24) employ an arrangement in which the reservoir in an inverted position serves also as a coverforthe pump housing or inlet. 
     For optimum compactness, the inlet (122) is provided laterally at the pump housing. In particular, the inlet (122) may be located in a side wall 55 laterally of a part of the pump housing (22) serving as a first supporting base (38) in an upright position thereof (Figure 1), and the pump housing has a second supporting base (56) laterally of the first base (38). In practice, the pump housing is laid on its side or second supporting base (56), whereby the inlet 122 comes to face upwardly (Figure4). Liquid is then pumped from the reapplied reservoir (24) while the pump housing is lying on its side.

Inventor: JUDD IAN DAVID
IPC: G09G1/04
Filed: 1980-10-31
Abstract: Cathode ray tube drive circuitry in which non-linearity of the line scan is corrected by varying the frequency of the pel clock oscillator in accordance with anticipated variations in scanning speed. Predetermined speed corrections are stored in digital store 23 and, by means of digital to analogue converter 24 and integrator 25, are applied to the control input of a voltage controlled oscillator 13. Synchronization of the pel clock with the X-deflection waveform is effected by means of a parallel phase-locked loop comprising counter 15, sample and hold 18, amplifier 20 and low pass filter 21. 
     Preferably a sinusoidal waveform is applied to the X-deflection coil in such a manner as to have a bidirectional raster scan, the X-deflection coil forming part of a tuned circuit of the sinusoidal waveform generator.

Abstract: For the continuous production of combustible gas from organic material, in particular from organic wastes, the wastes are dried in a continuous mass flow, degassed and gasified with an added gasifying agent. A shaft furnace (4) is used here, in which the shaft is separated from the downstream chamber by a passage (19) in the form of annular gap or longitudinal gap. In a first procedure, all processes take place in the loose bed (15) of material located in the shaft. For a second procedure - for achieving higher throughputs - an apparatus having a shaft furnace with a likewise gap-shaped passage is provided, a first chamber (34), for example a rotary kiln, in which drying and degassing down to the formation of coke is carried out being arranged upstream of the shaft furnace. In both process variants, the gasifying agent is added in the flow direction of the material, and in particular not later than the start of the gasification phase. The addition of the gasifying agent is here controlled as a function of the composition of the material, especially as a function of the temperature which establishes itself in the red-hot bed. <IMAGE>

Abstract: Control apparatus, typically for carburettors, which comprises an actuator device (20) having a permanent magnet armature and a pair of coils surrounding the permanent magnet, and a microprocessor (18) responsive to certain parameter-sensed variables including pressure (12), temperature (14), throttle conditions (16) and oxygen content (10) in order that these variously sensed parameters can be com- municatedtothe microprocessor wherein there is transduced by algorithm either a digital signal or an analog signal. The digital or analog signal is then fed to the actuator device in the form of a demand signal for currentflowto the armature coils. The coils upon energisation mechanically displace the arma- tureto effect mechanical transducing ofthe electrical signal to control an actuator rod effecting orifice control. The armature thus effectively controls the orifice size, which in turn determines fuel/air ratio for an internal combustion engine, in conjunction with a carburettor function. Fuel-air control creates operating conditions which in turn are re-sensed by the sensors, the sensors in turn repeating their operation so that there is provided a closed loop servo system either by digital oranalog signals.

Abstract: The charging device contains a two-part conductor bar (18', 18''), the two parts of which can be connected by means of a contact pair (32). When the contact pair is closed, the conductor bar connects a connecting terminal (15) for the accumulator battery (16) to be charged with the primary winding of a firing transformer (37) and with a device (33, 34, 36) for energizing the firing transformer as a function of the voltage of the battery. When the contact pair is opened, the primary winding of the firing transformer and the aforementioned device are separated from the connecting terminal. In addition a control circuit (31) for the contact pair is provided, which receives a first input signal from a timer (26) and a second input signal from a series resistor (12) in the charging circuit. The control circuit contains means which close the contact pair during the period determined by the timer, so that the firing transformer is energized as a function of the voltage of the battery, and open the contact pair after expiry of the predetermined period as soon as the charging current exceeds a presettable value. In this manner it is possible to charge a battery and/or to maintain a limited maintaining charge during a period of any desired length and to interrupt the charging operation when a battery does not reach the set-point of its voltage in the predetermined period.
