Patent GB-652276-A (GB)
Title: Process for the manufacture of aromatic nitro compounds
Filed: 1948-12-15
Abstract: Aromatic nitro compounds are manufactured by nitrating compounds of the general formula <FORM:0652276/IV (b)/1> (wherein R3 represents hydrogen or an alkyl radical of not more than 4 carbon atoms, and R4 and R5 are the same or different and represent hydrogen, halogen, or alkyl or alkoxy radicals of not more than 4 carbon atoms).  The nitration is effected with concentrated sulphuric acid-nitric acid mixture, with 100 per cent nitric acid or with fuming nitric acid, and the temperature should be kept between -20 DEG  and +10 DEG  C., preferably about 0 DEG  C.  The starting materials and the products exist as structural (regular and pseudo) and optical isomers. Examples describe the nitration of the diacetate of dl-reg.-1-phenyl-2-dichloroacetamidopropane-1 : 3-diol, and of the triacetyl derivatives of dl-#Y- and dl-reg.-1-phenyl-, dl-#Y-1 - o - methylphenyl-, dl - #Y - 1 - m - methoxyphenyl-, dl-reg.-1-(31 : 41-dimethylphenyl)- and 1 - o - chlorophenyl - 2 - aminopropane - 1 : 3 - diol and dl - #Y - 2 - amino - 3 - phenylbutane - 1 : 3-diol. Specifications 652,272, 652,273, 652,274, 652,275, 652,277, 652,278, 652,279 and 652,280 are referred to.

Abstract: 1300727 Semi-conductors MOTOROLA Inc 23 March 1970 [3 April 1969] 13904/70 Heading H1K A semi-conductor structure is fabricated by applying an oxide layer by thermal oxidation or vapour deposition over a substrate 14 of high resistivity p conductivity material, and imposing an opening therein whereby an N<SP>+</SP> buried layer 18 (Fig. 4) can be diffused into the substrate. The oxide layer is etched away by HF, and an epitaxial N-type layer 21 is deposited on the substrate surface, and a further oxide layer 22 formed thereon by thermal oxidation or vapour deposition. Openings 24, 26, 28, 30 are made in the oxide layer through which p<SP>+</SP> impurity, e.g. boron is diffused into substrate 14 to form annular ring 32 providing PN junction isolation. A diffused resistor 33 may also be produced. Thereafter the surface mash is etched off by HF and a further oxide coating 36 is formed by exposure of layer 21 to heated gaseous oxygen and silane. A further thin layer 38 of phosphorus doped oxide is deposited on layer 36 by exposure to heated gaseous silane, phosphine, and oxygen. Mixed oxides and/or nitrides are also usable for the layers, and a photoresist mask 40 is deposited on layer 38 (Fig. 5) in which opening 42 is formed to permit etching out the exposed oxide with HF to expose the epitaxial surface 21, after which mask 40 is removed. N-type impurity of opposite conductivity type to the base region 34 is diffused in to define emitter region 48, and a superincumbent thin layer of phosphorus silicate glass 50 is thermally grown on region 48 and the surface of layer 38 during diffusion to minimize the depth of 48. A photoresist 52 is deposited on layer 50 into which openings 54, 56 are etched (Fig. 7) to expose layers 36, 38, 50, etched out by HF to expose the p-type regions; after which the photoresist is etched off and layer 50 is etched to reopen emitter window 60 (Fig. 9) into which a metallized emitter contact 62 is deposited, as is a metallized, e.g. aluminium strip 64 overlying oxide layers 36, 38 to connect base 34 to diffused resistor 44 (Fig. 10).  Junction F.E.Ts may be similarly fabricated, boron ion implant may replace impurity diffusion, and the diffusion masks may be a nitride or a phosphorus silicate glass.

Title: Improvements in and relating to electrical remote control systems
IPC: H02J13/00
Filed: 1945-06-04
Abstract: 593,550. Electric control systems. WOOLNOUGH, G. L., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. June 4, 1945, No. 14049. [Class 40 (i)] In a receiver for a remote control system of the type in which the response depends on the interval between two impulses, the reception of a first impulse causes a member driving a member actuating the means to be controlled to be released, and the reception of a second impulse causes the actuating member to actuate the means to be controlled. Figs. 1 and 3 show an arrangement in which a switch 50 is operated in response to a pair of relatively high-frequency impulses transmitted over power lines, and separated by a predetermined time interval. Motor 4 is suitably connected in series with resonance relay 2 'to the power lines and exerts a continuous torque on a shaft 6 which carries a fixedly mounted ,member 9, which is normally prevented from rotating by the engagement of a bimetallic element 18 in a recess 17 and a loosely mounted member 13. Members 9 and 13 are configured so that they tend to rotate together, but if 13 is stopped, the torque on 9 causes 13 to move axially, the relative rotary movement being limited by the engagement of a pin 22 in a slot 23. When a signal of suitable frequency is superimposed, the normally closed contacts of relay 2 open intermittently and current flows through coil 20 causing element 18 to move out of engagement with the member 9 and into engagement with slot 21 on member 13 owing to the greater length of slot 21. The element 18 does not move back into slot 17 on termination of the impulse, but rides along the periphery of member 9 as the system is rotated by the motor 4. Reception of the second impulse causes the element 18 to engage one of slots 24-32, the above-mentioned axial movement then takes place and if the interval between the impulses is of correct duration, pin 42 is in a suitable angular position to actuate switch 50. If no second impulse occurs, member 9 rotates until the element 18 drops into slot 17. A second pin 421 angularly displaced from 42 is provided so that switch 50 may be actuated the other way by two impulses separated by a different time interval. The left-hand face of member 13 is configured to take a number of pins for actuating different control mechanisms. The element 18 may be replaced by a suitable electromagnetic device, or a relay may be interposed between relay 2 and winding 20. Specifications 517,971 and 523,360, [both in Group XXXVII], are referred to.
