Title: Regeneration of Ion Exchange Materials
IPC: B01J49/00
Filed: 1979-07-30
Abstract: In the regeneration of mixed resins, separation and transfer of the separated resins is achieved by classifying into an upper anion layer, an intermediate interfacial region and a lower cation layer, transferring the latter from the bottom of the separator vessel and controlling the transfer by detecting an interface between materials.   In an illustrative embodiment, the interfacial region comprises inert material and cation material is transferred through elongate conduit 106 from separator/anion regenerator vessel 10 to cation regenerator vessel 12. Transfer is terminated in response to a change in conductivity at an interface between materials being detected by the instrument 110. This allows the interfacial region to be substantially isolated in conduit 106 during regeneration, thereby decreasing the contamination of the regenerated resins. <IMAGE>

Title: Improvements Relating to Approach Slope Indicators
IPC: B64F1/18
Filed: 1979-08-10
Abstract: The invention is an aircraft landing aid, in the form of an approach slope indicator unit which emits at least two sectors of steady light 27 and 28 above a lower sector of flashing red light 25. The indicator is used to indicate a correct angle of approach to pilots of incoming aircraft. It also provides a readily perceived warning by the flashing red light sector that the aircraft is flying too low The principal use of the indicator unit is on short runways or landing platforms, when high pilot work-load situations prevail and where the pilot is likely to be more readily aware of a flashing light rather than a steady light. <IMAGE>

Title: Lubrication arrangement in ic engine cylinder
IPC: F01M1/06
Filed: 1979-11-26
Abstract: A cylinder (9) has lubrication grooves (14-15; 22) formed in the wall thereof and to induce lubricant to flow along the full length of the grooves, lubricant from supply pipes (1) is fed into the grooves via supply bores (16, 17), which extend substantially in line with respective grooves or sections (14, 15) thereof.

Title: Injection molding method and device
IPC: B29C45/27
Filed: 1980-07-07
Abstract: Raw material such as rubber or synthetic resins is heated to a high temperature just before being injected into a mold cavity (48) by an intermittent heater (54) and is injected continuously into the cavity at that temperature. Heat capacity of the heater is small to obtain quick response and to give no heat to the raw material to be injected for the next product. The device of this invention comprises a device (24) for injecting a predetermined amount of raw material intermittently, a flow path for the raw material which connects said device (24) and the mold (42), and the electric resistant heater (54) in the flow path to generate Joule heat and to transfer the generated heat to the raw material flowing through said flow path. The heating of the material by the heater (54) shortens the period for vulcanization of the material in the mold cavity (48). <IMAGE>

Title: Method of and apparatus for controlling loads on an electrical power supply
IPC: H02J3/14
Filed: 1980-09-01
Abstract: To enable a consumer of electrical energy to effect control of total energy consumption by various individual appliances and loads, each individual load has a control unit, conveniently in a plug top, which responds to pulses broadcast on the power supply wiring in the form of short duration interruptions of the waveform. At each appliance a microprocessor unit counts the number of successive pulses in a predetermined time interval and operates an electronic switch if the received count reaches a predetermined number, which may be different for different loads thereby enabling selective control of the loads. Provision is made for automatic restoration of supply if the overall energy consumption falls. Provision can also be made for automatic resumption of supply after a predetermined time interval.

Title: Safety devices for flued gas appliances
IPC: F23N5/10
Filed: 1981-11-17
Abstract: The safety device comprises a gas control valve (11) in the gas supply line to a main burner (9) of the appliance and a thermocouple (14) heated by a pilot flame. The control valve has a valve member (4) urged on to a seat (3) by a spring (5), a manually operable push rod (12) for opening the valve member, and an electromagnet (13) which is connected to the thermocouple and which holds the valve member (4) in an open position when the pilot flame heats the thermocouple. A normally open temperature sensitive valve e.g. a fusible valve (16) is placed in the gas supply line to the pilot burner and at a position adjacent to an aperture communicating with the flue but not in the normal combustion product flow path of the appliance. If the flue becomes blocked, the combustion products are deflected over the fusible valve (16) which will close to cut off gas supply to the pilot burner. The e.m.f. to the electromagnet (13) will fall and the valve member (4) will close to cut off gas supply to the main burner. <IMAGE>
Patent GB-814061-A (GB)
Abstract: 814,061. Electric indicating systems. BRISTOL CO. Sept. 19, 1957 [Sept. 25, 1956], No. 29513/57. Class 40 (1). [Also in Group XXXVII] A detector-amplifier 17 derives, from the unbalance potential of potentiometer network 10, an alternating potential which is used to control a reversible servomotor 18 for rebalancing the network. The anode current of triode 19, in the output circuit of the amplifier, contains a D.C. Component upon which is superimposed an A.C. component, and, while the latter component provides for reversible operation of the motor in accordance with the sense and magnitude of the unbalance potential, the former provides a braking effect to afford damping and quick stoppage. A control winding 27 of the motor is shunted by capacitor 23 and is supplied from the output of the amplifier, this winding co-operating with a reference winding 26 which is connected in series with a phase-displacing capacitor 31. A motor-driven contact 13 engages a slide-wire 11 forming part of network 10, and, when the contact reaches either limit of its travel, contacts 34 or 35 are closed so that the winding 27 is shunted by resistor 33 and rectifier 32. This has the effect of reducing the A.C. component supplied to the control field winding and substantially suppressing the D.C. component, whereby the motor is stalled in its end-position without objectionable vibration whilst the rotor is held against rotation. A suitable choice of values for resistor 33 and capacitor 23 provides a minimum torque sufficient to drive the motor away from its limiting position when conditions require it to seek a balance-point within the operating range of the instrument. As shown, a source of electromotive force, the magnitude of which is to be measured, is represented by thermocouple 14 having leads connected between contact 13 and a further selected point in the network 10 in series with the amplifier 17. The motor-driven contact carries a pointer adapted to co-operate with a graduated scale 25. In a modification, the rectifier 32 is replaced by a triode having its grid connected to an intermediate point along a resistor between the anode and cathode of the triode. The rectifying properties of the valve may be adjusted by means of the grid-connection, thus enabling resistor 33 to be omitted, Fig. 4 (not shown).
Patent GB-2091882-A (GB)
Title: Electrical catalytic gas detection systems
IPC: G01N33/00
Filed: 1982-01-20
Abstract: Intermittent measurements of gas concentration are made using a "pellistor" or like catalytic sensing element while avoiding lengthy heating-up times. The resistor (17) of the element, serving both as heater and thermal sensor, connected in a bridge network (ABCD) having an associated servo loop which controls current supplied to the network (ABCD) via a transistor (21). An operational amplifier (23) in the loop is switched from a quiescent state, when the network (ABCD) is substantially de-energised, to an active state, when sufficient current is supplied to heat the element to operating temperature, and subsequently back to the quiescent state after a steady state condition is reached wherein the servo loop operates to hold the element at constant temperature; a voltage appearing on an output line (Y) is sampled while that condition applies to provide the measurement. Compensation for ambient temperature variations is effected by means of a simple reference circuit incorporating a semiconductor diode.A system for the controlling the sequential operation of the system is disclosed, Figure 5 (not shown.) <IMAGE>
