Abstract: 1498510 Change-speed control AUTOMOTIVE PRODUCTS Ltd 3 Dec 1976 [18 Dec 1975] 51924/75 Heading F2D In an electronically controlled automatic transmission for a vehicle in which a signal whose magnitude is indicative of throttle opening (from a potentiometer 15) is combined at a summing junction 16 with a signal indicative of vehicle speed (from a circuit 10), the resultant signal being supplied to electronic circuitry 14, a differentiating circuit 35, 36 is connected between the potentiometer 15 controlled by the throttle and the summing junction 16. The electronic circuitry 14 incorporates bi-stable trigger circuits having input voltage hysteresis and is additionally controlled by a manual selector switch 18. The effect of the differentiating circuit, comprising a capacitor 36 and a resistor 35, is to make a rapid movement of the accelerator pedal generate a signal which overshoots the value corresponding to the new position of the pedal and so a downshift may be initiated by such a rapid movement of the pedal even through a gradual movement to the new position would not cause a downshift. The new ratio is maintained after the new steady state value is attained due to the hysteresis. In similar fashion a sudden release of the throttle pedal may cause an upshift. The signal from potentiometer 15 is reduced as the accelerator pedal is depressed. The transmission has four forward speeds and reverse selected by hydraulically operated clutches and brakes controlled by circuit 14, output circuits 21 to 26 and solenoid valves 28 to 31 and is as described in parent Specifications 1,420,307 and 1,457,887.

Abstract: The novel 7a -methylestradiol and its 3-methyl ether are prepared from compounds of the formulae (II), (III), (IV), (V) <FORM:1087316/C2/1> <FORM:1087316/C2/2> <FORM:1087316/C2/3> <FORM:1087316/C2/4> (wherein R is a free or esterified hydroxy group together with a hydrogen atom or an oxo or lower alkylenedioxy group; and R1 is hydroxy or methoxy) by treatment with lithium and diphenyl in presence of diphenyl-methane, by pyrolysis, by reacting with an acid, and by reacting with a methyl metal compound and eliminating the hydroxy group from the resulting 6-hydroxy compound, respectively. A resulting 3-ol may be etherified and 17-substituents may be converted to the free hydroxyl group by known methods. Examples are given, a by-product in the use of compounds (V) being 3-methoxy-6-methyl-17b -hydroxy-D 1,3,5(10),6 -estratetraene.  D 1,3,5(10) - 3 - methoxy - 6,7b  - oxido - 17b  - hydroxy-estratriene is prepared by converting 6-dehydro-estrone to the 3-methyl ether, peroxidizing this to 6,7b -oxido-estrone 3-methyl ether and reducing this. D 4-3,17-Diodo-7a -methyl-19-hydroxy -androstene is prepared by reducing the enolacetate of D 4-3-oxo-7a -methyl-17b -acetoxy-androstene to give D 5-3b -hydroxy-7a -methyl-17-b -acetoxy-androstene, converting this by a series of steps, via 3,17b -diacetoxy-5a -chloro-6,19 - b  - oxido - 7a  - methylandrostane to D 4-3,17 - dioxo - 6,19b  - oxido - 7a  - methyl - androstene and heating this with zinc and acetic acid.  D 4 - 3 - Oxo - 6 - bromo - 7a  - methyl - 17b  - acetoxy -19-nor-androstene is prepared from D 3,5-3-ethoxy - 7a  - methyl - 17b  - acetoxy - 19 - norandrostadiene (prepared from the D 4-3-one) and N-bromosuccinimide.  These processes and other starting material preparations are also referred to in general terms.  The steroids of the invention, which are stated to be potent estrogens, may be made up into pharmaceutical compositions for enteral or parenteral administration.

Title: Vehicle guidance system
IPC: G05D1/02
Filed: 1972-11-14
Abstract: 1448984 Leader gear systems ELECTRICAL RESEARCH ASSOCIATION Ltd 9 Nov 1973 [14 Nov 1972] 52586/72 Heading H4U [Also in Division G3] In a system for steering a vehicle so as to follow a guidance cable, the steering machanism is operated by a fixed amount to left or right of a datum position in response to any deviation which exceeds a threshold value, and the mechanism remains operated until the deviation drops below the threshold. The cable carries A.C. which is detected either by two coils 6, 7, Fig. 6, at the ends of a boom in front of the vehicle, or by the coils 8, Fig. 7, at a single position, which are connected to the discriminator circuit shown. In either case a potential is established at the junction B of a voltage divider 13, 14 which, when the vehicle is centrally above the cable, is equal to a bias potential applied to point D, and which varies in a positive or negative direction relative to D according to the direction of deviation of the vehicle. B is connected to differential amplifiers 23, 24 in the manner shown, such that one or the other fully conducts when the potential at B exceeds a threshold value established by the resistor and diode chain 19 ... 22. This turns on one or the other sets of switching transistors 25, 26 connected in series with the supply to electromagnetic wheel brakes 27, 28 respectively, by which the vehicle is steered. Alternatively conventional steerable wheels may be actuated. In the event of loss of signal (below a value set on a resistor 31), e.g. due to a large deviation or failure of the A.C., a further differential amplifier 29 biases off a transistor 43, after a delay provided by a capacitor 45; 43 is in series with a relay 44 whose contacts 46 are then changed over to energize a fuel shut-off valve 48. After a further delay, sufficient for the engine to stop and obtained by capacitor 39, transistors 40 are also biased off causing a relay 41 to open its contacts 42 and thereby de-energize the control circuit and fuel valve 48. A switch 34 must be opened and re-closed to re-establish control. The control circuits but not the steering mechanism can be energized by a push switch 48; this is to test the circuit and establish that the vehicle is properly placed (indicated by a lamp 52) before automatic control is switched on. The vehicle may be an irrigation machine moving at 1 ft./min. There may be detectors at the front and rear, loss of signal from either causing reversal of the vehicle.

Cell 17 is composed of materials having the same refractive index and the wall member is preferably a transparent plate 18. A reflective backing member 20 defines with the plate 18 a chamber wherein the transparent fluid is disposed such that in the arrangement shown a beam of light e.g. 14, 14C will travel between the elements and be reflected 14D from the front reflecting surface 22 of the backing member 20 or from its rear surface 23, when the reflective coating is absent. Movement of the cell into and out of co-operation with the element 10 is achieved by Piezo-electric or magnetostrictive devices and this serves to provide digital offset of the incident light-beam. Fig. 6 (not shown) shows a device which can provide a continuously variable offset of the incident light-beam (over a larger range), according to an actuator which has for this purpose an inter-connected reservoir of fluid to enable the volume of the cell to be varied. The deflector may also be combined Fig. 5 (not shown) with others, not necessarily in the same place to provide a system giving a series of offset light-beams for a single incident beam. The light transmissive element may be a right angle prism a non right angle prism, a curved body or a non-planar body. Reference has been Directed by the Comptroller to Specification 1215209.
