Title: Partial Oxidation of Hydrocarbons.
Inventor: RUSSELL JOSEPH LEE
IPC: C07C29/52
Filed: 1967-05-10
Abstract: 1,189,695. Oxidation of hydrocarbons. HALCON INTERNATIONAL Inc. 10 May, 1967 [12 May, 1966], No. 21659/67. Addition to 1,123,583. Heading C2C. Hydrocarbons are oxidized to alcohols in a continuous process comprising reacting the hydrocarbons in the liquid phase with molecular oxygen in the presence of a boron compound, capable of forming an ester with the alcohol produced, in a plurality of reaction zones arranged in series, in which at least A per cent of the oxygen is reacted with liquid hydrocarbon containing a molar concentration of oxidized hydrocarbon of at least 1À5%, in which A= (x - 1À5/x).100 and x is the per cent total hydrocarbon conversion in the oxidation process, and a vapour effluent containing unreacted hydrocarbon is withdrawn from each of the reaction zones, these effluents are combined, unreacted hydrocarbon is separated therefrom by condensation and is recycled to the various reaction zones and distributed among them so that the required concentration of oxidized hydrocarbon in each zone is maintained. The preferred boron compound is metaboric acid but other suitable compounds are orthoboric acid, tetraboric acid, pyroboric acid and boron oxide. The ester obtained is hydrolysed to give the required alcohol. The process is applicable to hydrocarbons generally and especially to cycloalkanes, e.g. cyclopentane, cyclohexane, cycloheptane, cyclooctane and cyclodecane. Some of the ketone corresponding to the hydrocarbon is also formed.

IPC: G11C15/04
Filed: 1969-04-29
Abstract: 1,255,206. Transistor bi-stable circuits. MOTOROLA Inc. 29 April, 1969 [13 May, 1968], No. 21758/69. Heading H3T. [Also in Division G4] Cross-coupled transistors 28, 30 forming a bistable memory circuit 25, each have first input terminals such as emitters 34, 38 connected to a common word select line 32, and second input terminals such as further emitters 36, 40 connected to respective sense/write lines 20, 22, and a circuit 27 using for example transistors 60, 62 senses identity of logic state between the bi-stable and the write circuitry connected to lines 20, 22. For reading or writing, the word select line 32 is raised to + 3V BE , and the state of the bi-stable is read by whichever of the emitters 36, 40 conducts into its sense/write line, and is set by appropriately biasing the lines 20, 22 by means of the write circuitry. To detect identity between the bi-stable state and the write circuitry state by the so-called process of association, the word select line is held at a lower potential of 1V BE . Supposing a bi-stable "1" to be T28 ON and T30 OFF, and a write circuitry "1" to be line 22 at 1V BE  and line 20 at 3V BE , then neither of the transistors 60, 62 conducts and identity is indicated thereby. If the bistable is "0" however, T30 is ON and T60 emitter voltage is V BE +V CE(SAT)  (at T30 collector) plus the small voltage across resistor 52, and its base voltage being 3V BE  causes T60 to turn ON. This indicates lack of identity, and a sense amplifier 16 supplies this current flow at terminal 13 to the output 18. In an array of similar memory circuits any one circuit whose stored information is not of immediate interest may be masked or inhibited by holding both sense/ write lines at a certain potential, thereby forcing the memory circuit to indicate association.

Title: Improvements in methods of preparing secondary alkyl resorcinols
IPC: C07C37/18
Filed: 1934-07-26
Abstract: Secondary alkylresorcinols are prepared by treating resorcinol with a secondary aliphatic alcohol or secondary alkyl halide having at least seven carbon atoms.  The reaction is preferably effected at a raised temperature in the presence of a cationoid catalyst, and when an alcohol is used the water formed in the reaction is continuously removed.  The secondary alkyl group attaches itself to the resorcinol nucleus either through the carbon atom to which the hydroxy group of the secondary alcohol (or the halogen atom of the secondary alkyl halide) was attached, or through an adjacent carbon atom other than a terminal carbon atom.  In the examples: (1) resorcinol and n-octane-2-ol in the presence of zinc chloride yield 4-(n-octyl-3<1>)-resorcinol; (2) resorcinol and 2 - bromo - n - heptane in the presence of zinc chloride yield 4-(n-heptyl-3<1>)-resorcinol.  Secondary nonylresorcinols are stated to be obtainable.  Specification 398,218 is referred to.  The Specification as open to inspection under Sect. 91 states that the products are useful as germicides and antiseptics and may be incorporated in solutions, jellies or lozenges in a proportion of 0,5 per cent or more.  This subject-matter does not appear in the Specification as accepted.

Title: Blasting device
IPC: F42B3/06
Filed: 1959-06-29
Abstract: 901,089. Fluid-pressure blasting cartridges- OLIN MATHIESON CHEMICAL CORPORATION. June 29, 1959 [July 15, 1958], No. 22223/59. Class 9 (1). A fluid-pressure blasting cartridge is provided comprising a head 1 with discharge ports 10 closed by a sleeve valve 46 having openings 48 through which gas is leaked from the body 3 to a valve control chamber 16. Pivotally connected to the valve is a link 53 also pivoted on a link 41, which has a nose bearing against a lever 30. The lever 30 has pivotal connection with a plunger 25 and bears against a fulcrum at the end of a control shaft 37 adjustably held in a bore parallel with the plunger 25. A spring 31 bears against the head of the plunger and against a plug 32 in which the plunger can slide. By adjustment of the plug, the pressure of the spring may be altered. Passages 36 in the head 26 of the plunger allow gas to leak into the space around the stem of the plunger. When the pressure on the left-hand side of the head 26 overcomes the pressure on the other side combined with the resistance of the spring 31, the plunger yields and swings the lever 30, thus breaking the toggle 41, 53. The valve, thus released, moves and opens the ports 10 allowing the gas charge to escape. To prevent damage to the valve, a spacer ring 21 having an annular lip 22 is provided. As the valve moves to the open position, its skirt 47 enters an annular recess 23 surrounding the lip, the gas trapped in the recess acting as a cushion for the valve. The link 53 may be surrounded by a spring (not shown in Fig. 1), which returns the valve to its initial position after venting of the cartridge. In a modification, the control shaft is replaced by an adjustable screw and the plunger is rockably mounted. In Fig. 5, the swinging link 99 is provided with a return spring 145 and has a locking sear 138 which engages the end of the plunger 139 when the valve is closed. Movement of the link 99 is limited by an adjustable screw 101, extending through the link 99, coming into contact with a stop 102.

Title: Improvements in a semiconductor modulating device
IPC: G02F1/015
Filed: 1963-06-05
Abstract: 1,041,235. Semi-conductor devices. C.S.F.- COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. June 5, 1963 [June 8, 1962], No. 22284/63. Heading H1K. [Also in Division H4] Relates to a solidstate modulating device for infra - red radiation comprising a semi-conductor body having a junction formed between first and second regions of different types of conductivity (i.e. P- and N-type), the junction being subjected to a forward bias whereby minority carriers are injected from the first region into the second. The absorption of electromagnetic radiation depends on the concentration of minority carriers. Accordingly it is possible to modulate the radiation by varying the forward bias. In accordance with the invention the maximum permissible modulation frequency is increased by creating an electric field in the forward direction in the second region which has the effect of reducing the life-time of the minority carriers without substantially reducing the diffusion range. In one way of carrying out the invention, Fig. 3, the main body of the device, which is of N-type material, is provided with a P-type region 4 and an ohmic contact 3 between which a modulating voltage is applied, whilst a voltage source 2 is connected to apply an electric field in the forward direction throughout the N-region. In another way of carrying out the invention, Fig. 4 (not shown), the body of semi-conductor material is formed with a P-N junction, and in the N region the concentration of donor atoms is decreased progressively from the junction so that there is produced an internal field within the N-region acting in the forward direction.
