Abstract: 928,945. Controlling motor vehicles. E. SOLBACH. Nov. 10, 1960 [Nov. 18, 1959], No. 38683/60. Class 79(5) Apparatus controlling the drive and braking of a vehicle comprises a foot pedal 15, a drive push rod 7 with a plunger 8 in a primary hydraulic cylinder 9, a plunger 11 in secondary hydraulic cylinder 10 which normally moves in unison with pushrod 7 and is connected to the vehicle engine throttle or other speed control and a brake push rod 6 which withdraws hydraulic fluid from the hydraulic cylinders 9, 10 when depressed and returns the fluid when released. In Fig.. 1 on depression of pushrod 7 displacing plungers 8 and 11 to the left fluid passes from cylinder 10 through passage 36 and pushes piston 31 along pushrod 6 against spring 32. When the base of pedal 15 and pushrod 6 is also depressed, against a force 39 from the brakes, movement of plunger 30 withdraws fluid from the cylinders 9, 10 while piston 31 pushes fluid through passage 36 into cylinder 10 moving plunger 11 to the right and closing the engine throttle. A vent 34 is provided between plunger 30 and piston 31. In a second embodiment, Fig. 3, the body of the apparatus is a fluid reservoir from which cylinder 9 is normally sealed by the conical face 79 of the brake pushrod seating on face 61 of the body while fluid from cylinder 10 may enter the reservoir through passage 64. When the seal 79/61 is made fluid may return from the reservoir to cylinder 9 through one way valve 73. The hydraulic connection between the pushrods 6 and 7 may be replaced by a mechanical, electrical or pneumatic connection.

A planar transistor has emitter and base regions of a smaller lateral area than a collector region and connected to metallic electrode areas overlying the collector region on an insulating layer. A screening layer is provided between one of the electrode areas and the collector region and is connected to the other electrode area by a metallic stripe extending over the insulating layer. The screening layer, which is separated from the overlying electrode area by the insulating layer, is a semi-conductor region isolated from the collector region in which it is formed by a PN junction formed between them. The embodiment described is an NPN silicon transistor with its emitter electrode screened and is to be used in grounded base configuration at frequencies above 500 MHz. The N type wafer is provided first with a boron-doped base region 3 and screening region 28 by diffusion through an apertured oxide layer and subsequently with two partial emitter regions 2 by indiffusion of phosphorus. Aluminium is deposited over the entire surface and selectively etched away to leave base 6 and emitter 5 electrode areas and the stripes 27 interconnecting the screening layer of the base electrode area. The base contact fingers 17 and interconnecting stripes 27 are kept in a straight line to keep the output shunt capacitance low. The transistor is completed by the provision of a collector electrode and by encapsulation.

Patent GB-860842-A (GB)
Title: Improvements in or relating to the recovery or separation of aromatic hydrocarbons
Inventor: MCCAULAY DAVID A
IPC: C07C7/156
Filed: 1959-11-23
Abstract: Aromatic hydrocarbons are separated from non-aromatic hydrocarbons or different aromatic hydrocarbons by complex formation with hydrogen fluoride and a copper fluoride under anhydrous conditions.  Aromatic hydrocarbons form the complex and non-aromatics do not; one molecule of cuprous fluoride complexes two hydrocarbon molecules while one molecule of cupric fluoride complexes one hydrocarbon molecule, and the complex dissolves in the hydrogen fluoride.  In separating aromatics from non-aromatics preferably at least sufficient copper fluoride is used to complex all the aromatic hydrocarbon and 3-15 mols. of hydrogen fluoride are used per mol. of hydrocarbon (30-150 volume per cent based on hydrocarbon).  Temperatures of -40 DEG  to 150 DEG  C. are used under sufficient pressure to maintain the liquid phase.  The feed is preferably free of olefinic hydrocarbons and sulphur compounds. The resulting mixture may be distilled without separation; the non-aromatic hydrocarbons, possibly with hydrogen fluoride, are recovered first followed by the aromatic hydrocarbons and hydrogen fluoride at a higher temperature.  Solid copper fluoride remains. The separation of ethylbenzene and xylenes may also be effected, several stages being necessary to effect complete separation.  The "extract" phase containing the complex contains a higher proportion of xylenes and the "raffinate" a higher proportion of ethyl benzene.  Cuprous fluoride is added in amounts of 0.1-0.6 mol. per mol. of xylene and cupric fluoride in amounts of 0.2-1.2 mol. per mol.  Hydrogen fluoride is used in amounts of 3-30 mols. per mol. of aromatic hydrocarbon.  Non-aromatic hydrocarbons may be present but olefinic and sulphur compounds are preferably excluded. In a multi-stage operation the "extract" phase may be contacted with a xylene "reflux".  Continuous operation may be effected by passing the mixed feed and complexing agents to a distillation zone maintained at a temperature which will distil off the uncomplexed material while maintaining the hydrogen fluoride in a liquid condition, the complex being recovered at the base of the column.

The screw 22 rotates in a swivel nut 23 and the lever 17 abuts against a stop 24 against which it is held at a pressure determined by the screw 22. Alternative holes for the pivot 18 are provided in the lever 17 and bracket 14.

[Also in Division H3] A controlled rectifier 1<SP>1</SP>, which may be either a mercury arc valve or one or more thyristors, is fired when a light-sensitive device 1 is illuminated. The amplifier 2 (transistors 21, 22, 23) passes a current through the primary 31 of a pulse transformer 3 which has a pre-magnetizing winding 32. The primary current rapidly saturates the pulse transformer 3 and the signal induced in its secondary 33 fires the gate turn off switch 4 which controls the controlled rectifier 1<SP>1</SP>. When the illumination at 1 ceases the transformer primary 31 is deenergized and the bias winding induces a reverse signal which turns off the gate turn off switch 4. While the transformer 3 is resetting, the control electrode and cathode act as a Zener diode. The light-sensitive diode 1 may be photovoltaic rather than photo-conductive (Fig. 3, not shown). Winding 33 may be shunted by a Zener diode (41) (Fig. 4, not shown). The ON and OFF signals to 4 may take separate paths through different resistors (44, 45) and diodes (Fig. 5, not shown).

Abstract: 1344672 Automatic attitude control N G JOHANSSON 26 Aug 1971 [27 Aug 1970] 40175/71 Heading G3R [Also in Division E1] In a road maintenance machine, a blade is maintained horizontal, irrespective of the attitude of the machine, by hydraulic or pneumatic means, which are actuated by electrical pulses from a pulse generator via a switch, responsive to the inclination of the blade to the horizontal, the pulses being interrupted when the blade is horizontal. In the embodiment shown, the machine 1, Fig. 1 has a blade 2 supported on collar 3, cylinder 6 adjusting the angle of the blade to the direction of movement of the vehicle, cylinders 4, 5 controlling the inclination of the blade to the horizontal. A pulse generator, including resistors 13, 14 Fig.2 to set the pulse width and frequency respectively, capacitor C and transistor T 1 , in series with a winding of relay R across a D.C. source, supplies pulses to energise relay R, closing contact R 1  and energising electrically operated valves 10 or 11 according to the blade inclination as sensed by device 12, thus allowing fluid to pass via switch 8, from pump 7 to cylinder 4 whose double acting piston 4a is pivotably fixed to the collar 3 supporting the blade. Cylinder 5 is similarly controlled. Relay R may be omitted and the pulse applied direct to sensor 12. Faster correction, by increasing pulse width or amplitude, may be used if device 12 senses an inclination greater than a preset value. In an alternative, the pulse generator may be a variable speed motor operating a micro-switch.
