Title: An electrically alterable, nonvolatile floating gate memory device
Inventor: IPRI ALFRED CHARLES
IPC: H01L29/788
Filed: 1983-03-08
Abstract: An electrically alterable, nonvolatile floating-gate memory device is described wherein the floating gate (18) is a second-level polycrystalline silicon layer (18) and a first-level polycrystalline silicon layer (20) is provided with an aperture (16) in order to allow a small portion of the second-level polycrystalline silicon floating gate (18) to extend through the aperture (16) for coupling to the substrate (11, 10) at a "write" portion (W) of the channel region (15) of the device. By coupling the floating gate (18) to the substrate at the portion (W) of the conducting channel region (15) by means of the aligned charging aperture (16), chip area is conserved. A third level polycrystalline silicon layer (22) may be formed over the floating gate and be electrically connected to the first level polycrystalline silicon layer (20) which serves as the control gate. <IMAGE>

Title: Speed and power factor controller for a 3-phase induction motor
Inventor: SHEPHERD WILLIAM
IPC: H02P23/00
Filed: 1983-04-20
Abstract: The controller comprises a compensator element comprising an in line capacitor C having connected thereacross a damping resistor Rp, and a speed control element which comprises a thyristor chopper circuit in series with a load resistor RT connected in parallel with the compensator element. The use of a load capacitor RT in series with the thyristor chopper circuit enables the latter to be used in conjunction with a capacitive compensator, enabling high power factor to be realised at all speeds with a motor current remaining very nearly sinusoidal. In rush current at full voltage is reduced and a significant reduction in motor current is obtained to deliver a given torque at a given speed. <IMAGE>

Title: A hand machine tool provided with an auxiliary handle
Inventor: NOSS KLAUS
IPC: B25F5/02
Filed: 1983-05-06
Abstract: The hand machine tool (2), which is used selectively, for chiselling, hammering, drilling and/or percussion drilling, has a housing (3) to one end of which is fixed a main handle (5).

Title: Treatment of an aqueous medium to reduce ammonia content thereof
Inventor: HURLEY BARRIE SYDNEY
IPC: C02F3/20
Filed: 1983-05-10
Abstract: A method of reducing the concentration of ammonia in an aqueous medium containing ammonia/ammonium ions, e.g. a leachate emanating from a refuse tip, which comprises subjecting the aqueous medium to a plurality of cycles comprising a period of aeration, e.g. diffused air aeration, followed by a quiescent period, each period being for example 1 hour, whilst maintaining the pH of the aqueous medium to a value of at least 9.5, preferably at least 10.5. The method improves the efficiency of ammonia removal relative to the volume of air utilised and hence the operating costs compared to conventional ammonia stripping by aeration.
Patent GB-2139576-A (GB)
Title: Stair climbing devices
Inventor: COLPUS DOUGLAS RONALD JAMES
IPC: B62B5/02
Filed: 1983-05-13
Abstract: A stair climbing device as well as a method of using the device. The device in a preferred embodiment is a wheelchair. The chair is mounted on a floating chassis having a wheel assembly (150, 200) at each corner, each wheel assembly (150, 200) consisting of a pair of wheels (160, 170, 180, 190) mounted on arms (161, 171, 211, 221), the wheels (160, 170, 180, 190) being drivable about their own axes (169, 179, 219, 229) and the arms (161, 171, 211, 221) being drivable about the common axis (121, 141) by which they are connected to the floating chassis. The chair portion is connected to the chassis via pivots at the front end of the device and by extensible cylinders (400) at the rear end of the device so that the chair can be kept horizontal whilst the chassis can become inclined as the wheelchair goes up and down stairs. The arrangement is such that the device can also be used to raise and lower the chair relative to the chassis while the chassis is remaining horizontal. Thus the front pivoted connection is via a linkage arm. The method of ascending and descending stairs is that the chair rolls along, preferably backwards, when the device is ascending stairs, until the rearmost wheel contacts the riser of the first step, this producing a signal in suitable sensors, and then the drive mechanism is arranged to rotate the arm of the then rearmost wheel of this first wheel assembly that contacts the first riser so that the arm rotates around the common axis to bring the wheel onto the tread of the first step and as soon as this contact is sensed this wheel is driven into the riser of the first step until contact is again sensed, the arm of this wheel is then rotated towards a vertical position which draws the now trailing wheel of this assembly up the step and then the rotating movement is carried out again. This sequence is carried out in turn with the front and rear assemblies and the front and rear wheels of each assembly until the device has reached the top of the stairs and all wheels sense only upward pressures.

Title: Method and system for indicating storage battery capacity
Inventor: SAITO YOICHI
IPC: G01R31/36
Filed: 1983-08-30
Abstract: The capacity of a storage battery (1) is indicated on the basis of a terminal voltage detected before a load (3) is connected to the battery. The above capacity is stored and then updated a predetermined time period after the load has been disconnected from the battery. Although the battery terminal voltage tends to restore in accordance with different time constant curves according to the magnitude of the load applied to the battery, it is possible to indicate the battery capacity reliably without being subjected to the influence of the magnitude of the load. A battery voltage detecting section (41) detects the voltage across the terminals of a storage battery (1), a battery voltage storing section (42) stores the voltage, a memory timing presetting section (43) presets the storing timings of the section (42) according to the state where the load (5) is being connected to the battery or disconnected therefrom, and a driving section (44) amplifies the output signal from the section (42) and supplies an indicator (45). <IMAGE>
