Title: Temperature-dependant leakage current compensation
Inventor: HENRY PAUL M
IPC: H03F3/345
Filed: 1982-07-19
Abstract: The leakage current of a junction field effect transistor (1) is supplied by a second junction field effect transistor (2) having its drain and source electrodes both connected to the gate circuit of the first said transistor. A first adjustable voltage control device is connected in the gate circuit of the second transistor and a second adjustable voltage control device is connected across the source and drain electrodes of the first transistor. In order to reduce the leakage current to a minimum over a broad range of temperatures the circuit is heated to a temperature of about 150 DEG C and the first adjustable voltage control device is adjusted to bring the leakage current through the second transistor equal to the leakage current of the first transistor. The second voltage control device is then adjusted to reduce the leakage current of the first transistor to a minimum. In a differential amplifier circuit, the first adjustable voltage control device (44) is adjusted to make the leakage currents of the two respective transistors (11, 22 and 33, 42) on each side equal, and the second voltage control device (66) is then adjusted so as to reduce the leakage current differential of the two sides to a minimum. The technique is applicable to other semi-conductor circuit arrangements. <IMAGE>

Patent GB-2157076-A (GB)
Title: An electromagnetic radiation detector
Inventor: SABET COOROSH
IPC: H01L31/0224
Filed: 1984-03-15
Abstract: A body of semiconductor material 4 lies between two electrical contacts 1 and 2 one of which may be transparent. An oscillator 5 impresses a signal at a frequency ???p across the semi-conductor body. A band pass filter 6 excludes harmonics of ???p from the input circuit. A band pass filter 7 in an output circuit blocks the input signal frequency ???p but passes a harmonic frequency ???s, e.g. the second harmonic. The contacts 1 and 2 provide symmetrical electrical boundary conditions for the semiconductor body 4. When irradiated either through one contact or through an insulating mask 3 free charge carriers are generated, thereby creating asymmetry in the bulk distribution of charge carriers and enhancing the non-linearity in the semiconductor material 4. The non-linearity causes a signal at the harmonic frequency ???s to be generated in the output circuit. <IMAGE>

Title: Sprung chuck key
Inventor: SCIAMMA JOEL MATTHEW
IPC: B25B33/00
Filed: 1984-04-14
Abstract: A sprung chuck key, has a handle 10 on which is fixed a pinion 18 through which passes a coaxial co-operating pin 14 that is sprung so that it is normally retracted within the pinion. Button 13 is provided so that the operator may push the pin into its working position, out of the pinion. The coiled compression spring 15 is coaxial with the shaft of the pin. Due to the action of the spring against the annular shoulders 16 & 17, withdrawing the pin into the pinion, the chuck key may not remain in position on the chuck which it fits unless pressure is applied to the button. A hole 20 is provided in the handle so that the chuck key may be attached on or near the equipment that uses it. A recess 19 is provided within the handle to enhance the grip. <IMAGE>
Patent GB-2140415-A (GB)
Title: Separation of anionic from nonionic alkoxy compounds using silica gel
Inventor: BROWN PETER JOHN NICHOLAS
IPC: B01D15/00
Filed: 1984-05-10
Abstract: Anionic alkoxy compounds are separated from non ionic alkoxy compounds by a method which involves contacting a solution containing both materials with silica gel which preferentially adsorbs the anionic compounds. The latter may then be recovered by desorbing with a suitable solvent. The method is particularly suitable for purifying alkyl aryl ethoxy sulphonates formed by ethoxylation and sulphonation reactions which give rise to a crude product containing anionic and non-ionic compounds. The purified compounds are suitable for use as surfactants in enhanced oil recovery.

Title: An excitation regulation system for alternators
Inventor: BONATO SILVANO
IPC: H02P9/38
Filed: 1984-05-31
Abstract: The field winding 100 of an alternator is energised from the phase winding 90 by both a voltage regulator B and the secondary of a circuit transformer A. The primary 60 of the current transformer A is connected in series with the winding 90 and its main load and the secondary is connected to a tap 3 on winding 90 so that the secondary gives a current dependent on both the load current and the generator output voltage. This secondary current is fed to field winding 100 via rectifier 52, 53, 44. A triac 30, or an SCR or transistor, in a further regulator C becomes conductive to divert part of the secondary current away from field winding 100 if the generator output voltage exceeds a preset value. <IMAGE>
