Title: Improvements in or relating to the preparation of chlorphenoxy compounds
Inventor: BARKER HENRY JAMES
Filed: 1950-12-06
Abstract: Chlorophenoxy acetonitriles are prepared by reacting a chlorophenoxymethyl monochloride with an alkali metal cyanide in a solvent medium comprising a ketonic solvent together with a minor proportion of water, optionally in the presence of a catalyst. The chlorophenoxymethyl mono-chlorides contain at least one chlorine atom but no other nuclear substituent, and are prepared by liquid-phase chlorination of compounds of formula R.OCH3, R being a benzene nucleus containing at least one chlorine atom, optionally in presence of a catalyst, e.g. phosphorus tri- and penta-chloride and sulphur mono-chloride.  The alkaline hydrolysis or acid catalysed alcoholysis of 2 : 4-dichlorophenoxyacetonitrile yields 2 : 4-dichlorophenoxyacetic acid or its ester respectively.  In examples: (1) Anisole is chlorinated using phosphorus pentachloride as catalyst to produce 2 : 4-dichlorophenoxy methyl monochloride, which with potassium cyanide in aqueous acetone yields 2 : 4-dichlorophenoxy acetonitrile.  This on alkaline hydrolysis furnishes 2 : 4-dichlorophenoxyacetic acid together with bis-(2 : 4-dichlorophenoxy)-methane as by-product.  (2) Example (1) is repeated, commencing with 2 : 4-dichloroanisole and employing sodium cyanide to form the nitrile.  (3) 4-Chloro-anisole is chlorinated to yield 4-chlorophenoxymethyl monochloride which is converted to the corresponding nitrile as in (2).  Specification 712,478 is referred to.

Title: Process for forming metal contacts on semiconductor devices
IPC: H01L23/485
Filed: 1969-06-12
Abstract: 1276542 Semi-conductor devices HIRADASTECHNIKAI IPARI KUTATO INTEZET 12 June 1969 [12 June 1968] 29966/69 Heading H1K During semi-conductor device manufacture apertures photolithographically defined in a Mo layer 17 are used to restrict the extent of etching of an underlying insulating layer 3 to open contact windows therein. An Al layer 18  applied over the entire surface then makes contact with the semi-conductor surface through these windows. In the Si MOS transistor illustrated the combined Al/Mo layer is then etched to the desired shape by the photolithographic method. Alternatively only the Al layer 18 may initially be shaped, following which the Al is alloyed to the Si in the contact windows, the Mo layer 17 remaining everywhere to protect the oxide layer 3 during alloying. Finally the Mo layer 17 is also etched to the desired shape. Au wires may be bonded to the Al layer 18.
Patent GB-445713-A (GB)
Title: Improvements in or relating to vehicles propelled by internal combustion engines
IPC: B60T13/48
Filed: 1934-10-19
Abstract: 445,713. Controlling motor vehicles ; fluid-pressure brakes. TAPP, E. T. J., 10, Manville Road, Tooting Common, London. Oct. 19, 1934, No. 29975. [Class 79 (v)] [See also Group XXXIV] In a vehicle of the kind wherein governor controls the brake and throttle whenever a predetermined vehicle speed is exceeded, the brakes are controlled by the vacuum created in the engine induction pipe by the closing of the governor throttle. The governor may act on the usual driver-controlled throttle or on a separate throttle. In the construction shown in Fig. 1, the throttle b is controlled by the accelerator pedal through a spring l, and by the governor (not shown) through a rod c and a stronger spring g. When a predetermined vehicle speed is reached the governor rod c moves to the left and first closes the throttle after which one of two collars n on the rod rocks a lever m and opens a valve f connecting the brake pipe e with the induction pipe a in which there is a vacuum caused by the closing of the throttle. When the speed falls again the rod c moves to the right, opening a valve f<1> connecting the brake pipe e to the atmosphere. In the construction shown in Fig. 3, the throttle b is operated by an arm s connected to the accelerator pedal (not shown), and the governor rod c is connected to an arm t of a rotary valve o which can connect the brake pipe e either to the induction pipe through a port q or to the atmosphere. The arm s is normally held by a spring against a stop t<1> on the arm t so that the two arms are moved together by the governor rod until the throttle is closed, after which the arm t moves alone to apply the brakes. In the construction shown in Fig. 5, the accelerator pedal controls a throttle 7 and the governor a throttle 6. A flexible diaphragm 5 communicates through pipes 9, 11 with the induction pipe above and below the throttle 6 so that when 6 is open the pressure above and below the diaphragm is equalized. When the governor closes the throttle 6, the pressure below 6 is greater than above, the usual throttle 7 never being completely closed, so that the diaphragm 5 moves upwards and a valve 4 connects the brake pipe 13 to the pipe 11 and the induction pipe to apply the brakes. The diaphragm movement may be accelerated by an additional valve 10 which is opened as the throttle 6 closes and admits air to the lower side of the diaphragm. The valve 4 may control the supply of pressure fluid to the brakes if they are of the pressure-operated type. In tractor-trailer vehicles the brakes may be applied on both vehicles or on the trailer only. According to the Provisional Specification the governor (1) may act directly and successively on the throttle and a brake valve, or (2) applies centrifugal brake pads against a surface which first rocks slightly to operate the brake valve, further increase in speed causing these pads to act as a mechanical brake.

Title: Improvements in chamfering mechanism and method of chamfering gears
IPC: B23F19/10
Filed: 1932-10-26
Abstract: 393,173. Chamfering gear teeth. GLEASON WORKS, 1000, University Avenue, Rochester, New York, U.S.A.- (Assignees of Hill, M. H.; 1000, University Avenue, Rochester, New York, U.S.A.) Oct. 26, 1932, No. 29997. Convention date, Dec. 31, 1931. Addition to 375,247. [Class 83 (iii).] The attachment for chamfering gear teeth, described in the parent Specification, is modified by the provision of a pair of shaping tools T, T<1> which are moved to chamfer simultaneously the sharp corners at the inner end of a convex tooth flank 126 and at the outer end of the opposite concave tooth flank 128. In the application to a bevel gear cutting machine having a rotary face mill for cutting a blank G, a bracket 20 carries an adjustable bearing block 21, Fig. 7, which is guided in the bracket by a tongue 27. A hub portion 30 having an inclined axis 31 carries an arm 35 on which the tool T is mounted. A second bearing block 40 secured to the block 21 has a hub portion 43, the axis 44 of which is slightly inclined to the axis 31, and this hub portion supports the arm 50 carrying the tool T<1>. Each chamfering tool, Fig. 6, consists of a shank 55 with a portion 54 of trapezoidal section terminating in a cutting edge 56. The tool T is adjusted in its arm by means of a screw 64, and is locked by a set screw 60. The tool T<1> is secured in a block 70 by a recessed locking stud and the block is adjustably mounted on a wedge 74 which is in turn adjustable in a guide 76 in the arm 50. Fine adjustment of the block 70 is provided by a screw 82 and the block and wedge are locked by a bolt 77. The tool arms are connected by links 92, 100 to a member 85, which may be rocked either manually, in setting up, by a handle 140, or by mechanism working in unison with the machine so that each tooth is chamfered immediately after it is cut. In the form shown the member 85 is rocked by mechanism including a solenoid the core bar of which is connected to an arm 105. A spring normally holds the arms 35, 50 in inoperative position but when the solenoid is energized, the arm 105 is rocked to move the tools inwards to effect the chamfering. The solenoid is energized each time the cutter is removed from the blank. The outer end of the bracket 20 may be braced by a member 120. If sufficient clearance may be obtained between the arm 35 and the gear tooth milling-cutter, the axes 31, 44 may coincide. The axes 31, 44 are approximately perpendicular to a plane tangential to the root surface of the tooth space located at the point of operation and the tools are rotatably adjusted in their sockets in accordance with the pressure angle of the gear teeth.

Title: Production of vinyl acetate
IPC: C07C69/02
Filed: 1965-07-19
Abstract: Vinyl acetate is prepared by (a) reacting ethylene at 50-160 DEG  C. under a pressure of 50-2000 p.s.i.g. with an acetic acid working solution containing a Pd II salt, an ionizable metal acetate and a cupric salt oxidizing agent, whereby vinyl acetate, together with glycol acetates by-products, is produced, (b) removing vinyl acetate from the working solution, and (c) recycling the residual working solution containing the by-product glycol acetates to step (a) where the glycol acetates are converted at least in part to acetaldehyde simultaneously with the reaction of the recycled working solution with the ethylene in step (a) said working solution being re-oxidized before, during and/or after the recycling step.  It is preferred to use a working solution containing an amount of a metal halide which provides a molar concentration of chloride or bromide ions of 0.05-0.85. Vinyl acetate may be removed in step (b) by distillation whereby any acetaldehyde in the working solution is also removed, and this may be converted to acetic acid by oxidation with oxygen, which oxidation may be effected in the working solution after returning the acetaldehyde thereto.  Such oxidation, effected by the introduction of oxygen or air, also serves to re-oxidize the reduced working solution.  It is preferred to keep the bromide or chloride ion concentration below 0.9 molar, because at higher concentrations excessive amounts of glycol acetates may be formed, not all of which may be converted to acetaldehyde in step (c). If desired, accumulated glycol acetates may be recovered and purified.  Reference has been directed by the Comptroller to Specification 1,063,434.
