Abstract: 1,115,249. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. 29 July, 1966 [30 July, 1965], No. 32744/65. Heading H1K. An insulated-gate field effect transistor (F.E.T.) is formed on the surface of a semiconductor body from which a planar semiconductor device is made, part of an insulating layer on the surface lying beneath the metal gate-electrode of the F.E.T. A means of assessment of the reliability of the device is thus provided, for example by a measurement of the mutual conductance of the F.E.T. The device may be a double-diffused planar silicon bi-polar transistor, in which case P<SP>+</SP>-type source and drain regions of the F.E.T. may be diffused into an n-type crystal simultaneously with the base region of the bi-polar transistor. The gate insulator is then formed during a general surface oxidation stage, which also serves as the drive-in stage for the emitter diffusion. The metal gate electrode is evaporated on to the insulator. In another embodiment one of the F.E.T. electrodes serves as a guard ring to reduce the formation of unwanted surface channels from a junction of the planar device.

Title: Improvements in or relating to apparatus for containing and delivering material in powdered, liquid or semi-liquid form
IPC: A47K5/06
Filed: 1927-12-06
Abstract: 298,403. Rodriguez, A. M. Dec. 6, 1927. Fixed-chamber apparatus.-An apparatus for the delivery of measured quantities of powders, liquids, or semi-liquids, and particularly applicable for fixing above a lavatory basin for the delivery of powdered soap, comprises a container 4, which is moved forward by operating a fingerlever 12 and delivers the soap in the palm of the hand from a chamber 33. The container carries rollers 6 running on inclined rails 5 on the sides of a casing 2 fixed to the wall and is operated by a pin 15 on the lever 12, which engages a slot 16 in a bracket 17 secured to the container, the lever being pivoted at 11 to the casing. The measuring chamber 32 is controlled by two valves 18, 31 fixed on a spindle 19, which is guided in a bracket 23 and is formed with an arm 25 guided in a bracket 28. In the position shown, the spindle 19 rests on a rib 8 on the bottom of the casing and powder enters the chamber 32, the valve 31 being closed and the valve 18 open. When the container is moved forward, the spindle 19 rides off the rib 8 and the valve 18 is closed and the valve 31 opened by the engagement of the end of the arm 25 with a cam 41a on the casing situated above an aperture in the container. Powder then falls into the chamber 33, which is closed by a valve 34, slidable on the spindle 19, and pressed upwards by a forked lever 36, pivoted at 37, and carrying weights 40 at the ends of a cross-bar 39. On further forward movement of the container, heels 41 on the weights 40 ride up inclined stops 46 and allow the valve 36 to open. Alternatively, the weights 40 may be replaced by springs. The valve 31 may be dispensed with. The apparatus may be arranged to be operable only when the lavatory basin is full, and once, or twice, only at each filling. For this purpose the end 53 of a rod 43 pivoted to the lever 12 engages a rod 49 carried by a float 50 in a chamber 48, which communicates with the lavatory basin. When the float rises, the end of the rod 49 engages a lever 55 pivoted on the bracket 17 and resting on a stop 60. The lever 12 can then be operated, the end of the rod 43 entering a perforation 61 in the rod 49. When the container is moved forward, the rod 49 rises and prevents further operation of the lever 12. Two levers 55 with corresponding enlargement of the perforation 61 may be provided, to permit two operations of the lever 12. The rod 49 may carry an indicator visible through a window. The container is filled through an opening covered by a plate 62, which may be provided with a lock. The front of the container may be removable for inspection, and may be secured by an internal screw engaging a flange on the bracket 23.

Title: Improvements in or relating to asymmetric synthesis of alcohols
IPC: C07C29/74
Filed: 1963-08-20
Abstract: Optically active alcohols are prepared by hydrolysing the product obtained by reacting (a) a compound of formula RMgZR1, wherein R is a hydrocarbon residue having from 1 to 28 carbon atoms, R1 is a hydrocarbon residue having from 4 to 28 carbon atoms, at least one of which is asymmetric, and Z is -O- or -NR11, wherein R11 is R or R1, with (b) an unsymmetrically substituted carbonyl compound of the formula R111-CO-R1111, wherein R111 may be R or R1 and R1111 may be R111 or H, and R, R111 and R1111 must be different. Numerous examples of R, R1, R11, R111 and R1111 are listed. Reaction may take place at -50 DEG  to +150 DEG  C. at atmospheric pressure or above, e.g. under nitrogen, in absence of compounds containing reactive hydrogen atoms. The mole ratio of reactants is not critical.  Optionally a solvent e.g. excess carbonyl compound, ethers, inert tertiary amines and inert hydrocarbons may be used.  Up to two moles of associated magnesium halide may be present per mole of solvated RMgZR1. Hydrolysis of the reaction product may be achieved with an aqueous solution at pH 3-7, e.g. saturated ammonium chloride.  The alcohol may be recovered by washing the solvent layer, distilling off the solvent and distilling or crystallizing the alcohol.  Examples describe the reaction of ethylmagnesium - l - menthoxide with methyl isobutyl ketone to give laevorotatory 2,4-dimethyl-4-hexanol; the reaction product of methylmagnesium bromide and d-2-methylaminopropylbenzene with propiophenone to give methylethylphenyl carbinol enriched in d-isomer; ethyl magnesium d-2-octyloxide and acetophenone to give laevorotatory methylethylphenylcarbinol; phenylmagnesium d-2-octyloxide and methylethylketone to give laevorotatory methylethylphenyl carbinol; ethylmagnesium - l - borneoxide with acetophenone to give laevorotatory phenylmethylethyl carbinol; methylmagnesiumchlolesteroxide with benzaldehyde to give dextrorotatory phenylmethyl carbinol; phenylmagnesium - d-a  - tocopheroxide with 3 - methylcyclohexanone to give dextrorotatory 3-methyl-1-phenylcyclohexanol; and benzylmagnesiumchlolesteroxide with dimethyl-(2-benzoyl) propylamine to give laevorotatory 1,2-diphenyl-3-methyl-4-dimethylamino-2 -butanol.  Organomagnesium compounds RMgZR1 are prepared by reacting under anhydrous conditions a Grignard reagent RMgX, where R is as above and X is halogen with an optically active alcohol or amine R1ZH, where R1 and Z are as above. Alternatively, the Grignard reagent may be reacted with a compound Mg(ZR1)2. In an example, ethyl magnesium bromide is reacted with 1-menthol in dry ether to yield ether-solvated magnesium bromide-associated ethyl magnesium 1-menthoxide.
