Patent GB-2052808-A (GB)
Title: Method and apparatus for regulating an air ventilation or air conditioning apparatus
IPC: F24F11/00
Filed: 1980-06-06
Abstract: The error signal of a primary regulation circuit 10, 18, 20, 22, 24, 30, 32, 42, 44, 46, 50, 28, 52, 16 and 14 is infed as a control signal or magnitude to an air quantity auxiliary regulation circuit 24, 30, 32, 42, 44, 46, 50, 28 and 26. The quantity of supply air which is infed to the room or area which is to be ventilated or climatized, is proportionally influenced as a function of the regulation magnitude of the primary regulation circuit. A lower threshold and an upper threshold are adjusted for the infed quantity of air. In order that the proportional band, related to the room temperature, shall remain independent of at least the adjustment of the upper selected threshold or threshold value, the slope of the regulation characteristic of the proportional band is altered at least during adjustment of the upper threshold. By virtue of such arrangement, computation and post- setting of the proportional band is not altered at least during adjustment of the upper threshold. The primary circuit compares at 10 the actual room temperature, measured at 16, with a desired value set at 11. The auxiliary circuit compares at 24 the actual air flow or velocity, measured at 28, with the temperature error. The only corrector is a flap or valve 48. <IMAGE>

Title: Flat cooling plates or boxes for blast furnace walls
IPC: F27D1/12
Filed: 1981-03-31
Abstract: A flat circular cooling plate 100 is mounted between the furnace wall 101 and the refractory lining. A supply duct 103 extends through the wall 101 and supports the plate. The cooling liquid is supplied to a port 107 at the periphery and deflected by plate 108 to enter the enclosure 102 tangentially. Some of the outflow goes by way of port 109 and duct 110 to central chamber 111. Other liquid spirals inwards and passes directly into chamber 111 where spiral vanes 112 encourage the circulation. Outflow from chamber 111 is by a port opposite the vanes 112 and through a duct 104 coaxial with inflow duct 103. Similar structures can be used as cooling boxes with the plane of the box extending into the refractory perpendicular to the furnace wall. The direction of flow can be reversed with liquid entering at centre and leaving at periphery. <IMAGE>

Title: Drilling equipment and method
Inventor: D ARCY GEORGE PAUL
IPC: E21B47/12
Filed: 1981-11-13
Abstract: In order to provide improved control of drilling, e.g. of oil and other wells, at great depths, devices for measuring operating parameters are located near the drill bit and the resulting electrical signals are transmitted up the drill stack by means of a cable 4 formed from a plurality of length of cable arranged in the drill tubes 1. Appropriate connectors are provided and the cable 4 is protected from drilling fluid by means of a sleeve 2. The use of electrical telemetry enables information to be transmitted virtually instantaneously the surface for corrective or control action to be taken as required, thus leading to considerable reduction in drilling times. The turbine driving the drill bit may be provided with a bypass or dump valve to unload the power to the turbine rapidly thus reducing the incidence of damage to the drill bit arising from its being driven unduly rapidly into hard material. in the case of rotary drilling, the torque applied to the bit would be cut. <IMAGE>

Title: Automatic brightness control and warning circuit for image intensifier tube
Inventor: SHIMADA MITSUHIRO
IPC: H01J43/30
Filed: 1981-12-18
Abstract: In an automatic brightness control feedback loop for controlling the bias voltage of a microchannel plate 5 of an image intensifier tube 1, there are provided a gas discharge tube 52 and a photoconductor 99 which is optically coupled with the gas discharge tube 52. The brightness of the gas discharge tube 52 is controlled depending on the sensed current in the phosphor screen 8, and the resistance of the photoconductor 99 controls the multiplying rate of the image intensifier tube 1 accordingly. A delay is introduced in the signal path by capacitor 32 and capacitor 49. Automatic control of the brightness is provided, and when the incident light is excessive the discharge tube 52 is cut off, causing blinking of the image on the screen 8 to warn the operator to reduce the light input. <IMAGE>
Patent GB-2095917-A (GB)
Title: Electric motors
IPC: H02K29/00
Filed: 1982-01-25
Abstract: An electric motor drive, for instance of limited angle type for driving a servo-actuator, has two or more motor units 30,31 each including a wound stator 37,38 within each of which is a respective rotor 32, 33 carrying spaced permanent magnets, the rotors being carried out on a common shaft 34. Each stator has a number of slots 41 in which the stator windings 40 are recessed and adjacent stators are angularly offset with respect to their rotor poles by an angle equal to the slot pitch divided by the number of motor units. The cogging or superimposed varying torques of each motor which occur as the magnets pass a stator slot are thus out of phase and substantially cancel out. The invention may also be applicable to a continuously rotating motor and to a motor in which the permanent magnet field device forms the stator and the wound armature moves forming a rotor. <IMAGE>
