Title: Control system for the fuel supply system of an engine
IPC: F02D41/22
Filed: 1972-04-04
Abstract: 1429304 Automatic control of speed CAV Ltd 21 March 1973 [4 April 1972] 15350/72 and 15352/72 Heading G3R In a system for controlling the supply of fuel to an I.C. engine a safety circuit is provided to shut-down the supply of fuel if a speed measuring transducer produces no output or if the engine overspeeds. The fuel pump 11 of engine 12 is controlled by rod 19 operated by actuator 18 supplied from power amplifier 17 controlled by control circuit 15 in response to speed, pump output and demand signal inputs. The control system described is similar to those described in Specifications 1416861 and 1416862. A transistor 31 is normally held non-conducting by the voltage across capacitor 28 which is derived from the A.C. tachometer 13. When transistor 31 conducts under fault conditions it operates control 38 to cause control circuit 15 to reduce the fuel supply. In a modification transistor 31 may inhibit amplifier 17 directly or through safety network 45. Transistor 31 is switched off during starting. When engine 12 overspeeds the voltage produced at the output of diode pump circuit 14 causes transistor 44 to conduct and operate safety network 45 to inhibit amplifier 17. A duplicate control using transistor 86 is provided for maximum safety. The circuit shown may be modified to respond to failures in the diode pump circuit 14 by providing a long-tailed-pair arrangement to control the conduction of a further transistor, Fig. 7 (not shown).

Title: Doping semiconductor bodies
IPC: H01L21/00
Filed: 1973-04-02
Abstract: 1372162 Impurity diffusion process PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 2 April 1973 [5 April 1972] 15710/73 Heading H1K In a two-stage method of diffusing a dopant into a semi-conductor body the body is disposed between two locations for sources of dopant in a chamber which is movable relative to heaters which provide a hot zone between two cooler zones. After the first stage, in which only the body and a first dopant source are located in the hot zone the chamber is moved so that in the second stage only the body and the second source are in it. In the preferred embodiment the chamber has openings at its ends to permit a restricted flow of nitrogen or hydrogen through it. In the first stage this carries zinc from a zinc gallium alloy source towards tellurium doped gallium arsenide wafers in a holder, and some zinc condenses at the opposite cool end of the chamber to form the source used in the second stage for which the gas flow is reversed. For the cooling stage the flow is again reversed. Throughout the process the hot zone is at 830‹ C. and the cooler zones at 200‹ C. The first stage, which lasts 50 minutes gives a junction depth of 6Á and surface concentration of 5 x 10<SP>18</SP>-10<SP>19</SP> atoms/c.c., while the second stage, lasting 1-5 minutes, provides a 1Á surface contact layer containing 10<SP>20</SP> atoms/c.c. In an alternative method the first and second sources are zincgallium and zinc arsenide respectively. When using other dopants or semi-conductor bodies, e.g. other A III  B V  compounds the hot zone may comprise two regions at different temperatures which may be altered between the two stages of diffusion, and the chamber may be sealed or have only a single restricted opening.

The secondary may have a number of turns, and the recess 22 may face radially inwards or outwards. The coupling coefficient is stated to be relatively independent of the relative angular position of the primary and secondary provided the circumference of each is less than a wavelength at the frequency of the signals coupled.

Filed: 1943-10-05
Abstract: In the production of acidified malt in accordance with Specification 339,047, [Class 14 (ii)], the germinated cereal is steeped in a lactic acid solution prepared by the proliferation of lactic acid bacteria in a mash of malt and barley or the like, and the residual liquid which does not pass into the germinated cereal is made up in a separate vessel to its original volume by the addition of a further quantity of lactic acid solution similarly prepared and, after being left to allow formation of additional lactic acid, is employed in steeping a fresh batch of germinated cereal.  After about ten steepings the liquid begins to deteriorate and is thereupon rejected.

Filed: 1944-08-28
Abstract: 657,671. Self-levelling arrangements. KUIJVENHOVEN, A. W. Aug. 28, 1944, No. 16345. [Class 113 (i)] [Also in Groups XX, XXI and XXXVIII] Gyroscopic apparatus providing a stabilized horizontal datum plane or stabilized horizontal and vertical datum planes with respect to which stabilizing impulses about three rectilinear axes may be transmitted to stabilize and control apparatus such as gun-mountings, directors, sights, searchlights, &c. comprises a further gimbal system resolving these stabilizing impulses into corresponding impulses with respect to a biaxial system of axes by means of which apparatus mounted for movement about two axes only may be stabilized. Fig. 1 shows an application of the invention to gyroscopic apparatus G1-G2 of the kind described in Specification 657,668, erected by torque motors and switches as described in Specification 657,670, [Group XX]. As described in Specification 657,668, this stabilizer can be used to stabilize triaxial equipments by impulses transmitted from transmitters T3 and T7. To control biaxial apparatus impulses are obtained from transmitters associated with frames F9, F10 controlled by a transmitting frame F8. Frame F8 is positioned by motor M3 about axis A10 for angle of sight by an external transmitter supplying generated elevation and transmitters 11, and this angle of sight is transmitted to frames F9 and F10 by mechanical means, and by electromagnetic means energizing motor M6 respectively, by pick-up P2. Transmitters T13 then carry stabilized elevation relative to the deck and transmitters T14 training relative to stabilizer training. A modification is described wherein the inner gyro-stabilizer comprises a single gyro-vertical only. In this modification and in a further modification using the double gyro-stabilizer the transmitting frame may be positioned relative to the stabilizer to incorporate the correction for gun training (lateral deflection), this latter modification being used to stabilize and control a triaxial director and a biaxial gun-mounting. A modification is also described having two transmitting frames each associated with a pair of further frames, one of the transmitting frames being positioned to incorporate the correction for gun training, the whole being used to stabilize and control a biaxial director and a biaxial gun-mounting. The transmitters may form part of any convenient electrical system (see Group XXXVIII), or mechanical system for the transmission of angular data to energize the motors effecting the control of the associated apparatus.
