Title: Chloroborine etherates, their production and use
IPC: C07C205/19
Filed: 1958-06-19
Abstract: The invention comprises chloroborine etherates of the formula H2ClB:OR2 or HCl2B:OR2 where OR2 is an aliphatic ether, a cyclic ether or an ether of ethylene glycol. A chloroborine etherate is made by reacting boron trichloride with diborane or metallic borohydrides in the presence of an aliphatic ether, a cyclic ether, or an ether of ethylene glycol.  Suitable borohydrides are the alkali metal borohydrides, e.g. sodium borohydride. Simple ethers of the formula R2O in which R is an alkyl radical, cyclic ethers such as tetrahydrofuran or tetrahydropyran, or dialkyl ethers of an ethylene glycol or polyethylene glycol RO(C2H4O)nR in which R is an alkyl radical of up to six carbon atoms and n is one or a larger integer, are suitable solvents. The chloroborine etherates may be used to reduce carboxylic acids, nitriles, aldehydes, ketones, lactones, azo compounds and t-amides. Examples describe the reduction of (7) p-nitrobenzoic acid to p-nitrobenzyl alcohol; (8) p - chlorobenzoic acid to p - chlorobenzyl alcohol; (9) benzonitrile to benzylamine; (10) p - tolunitrile to p - methylbenzylamine; (11) acetophenone to phenylmethyl carbinol; (12) m-nitrobenzaldehyde to m-nitrobenzyl alcohol; (13) gamma-butyrolactone to the corresponding glycol.  The chloroborine etherates react with olefines at temperatures from 0 to 100 DEG C. to form organoboron compounds.  Ethers or inert hydrocarbons may be used as solvents.  When monochloroborine etherates are used, a major product is ClBR211 where R11 is the saturated radical derived from the olefine.  When dichloroborine etherates are used, the major product is Cl2BR11.  In examples, BH2Cl etherate reacts with cyclohexene to give ClB(C6H11)2 and tricyclohexyl boron, 2-hexene to give ClB(C6H13)2 and trihexylboron, ethylene to give ClB(C2H5)2. Cl2BH:OR2 reacts with 1-octene to give Cl2BC8H17, or with ethylene to give dichloromonethyl borine.

July 10, 1931, No. 19902. Convention date, July 10, 1930. [Class 40 (v).] Frequency modulation is effected by varying a resistance associated with a capacity, the capacity-resistance combination being connected to or coupled with the frequency control circuit of the carrier source. The capacity is the apparent input capacity of a thermionic valve, and the resistance is in its plate circuit and may comprise the plate-filament path of a second valve. This arrangement is shown in Fig. 3, in which the tuned circuit 16 of a valve generator 28 is connected across the grid and cathode of a valve 2, so that the input capacity of this valve is in parallel with the tuned circuit 16. The effective value of this capacity is varied by varying the external plate resistance of the valve 2. This resistance may comprise the modulating microphone, but as shown it comprises the plate-filament path of the valve 30, and the grid 32 of this valve is coupled to the microphone circuit 34, or to the circuit of a modulating source 38 and key 36. The signal produces variations in the frequency of the wave generated by the valve 28, which wave may be amplified at 40 and transferred to an aerial 41. The plate-grid capacity of the valve 2 may be supplemented by a condenser 39.

Title: Valve system

Abstract: 1,271,323. Valves. AMOT CONTROLS CORP. 22 April, 1969 [24 April, 1968], No. 20525/69. Heading F2V. [Also in Division G4] A fluid valve has an axial bore containing a sliding part which, dependent on its axial position, connects together various ports, the sliding part being moved by one or more pistons driven by a mechanical or fluid input. The valve cylinder is of modular construction, the modules being connected by snap connectors 86-91. In a first embodiment, Fig. 3, the sliding part 12 is formed integrally with a piston 13. If a mechanical force is applied to actuator 14 or fluid pressure applied to port 16, piston 13 and sliding part 12 are moved to the right until sealing ring 71 reaches the right-hand end of cylinder 61. At this point any fluid entering port 16 is discharged at port 17. Also fluid entering port 82 passes to port 83 and drives piston 94 leftwards, fluid at the left of piston 94 passing in to port 81 and discharging at port 17. When the force on actuator 14 and the fluid pressure at port 16 are absent, spring 41 drives the sliding part 12 and piston 13 back to the position shown so that fluid at port 82 passes to port 81 and drives piston 94 rightwards, fluid to the right of piston 94 passing via port 83 to discharge at port 21. In a second embodiment spring 41 is omitted, return of the sliding part being caused by a mechanical force applied to actuator 23 or by fluid pressure at port 22. In a third embodiment, Fig. 4, sliding part 12a is moved in response to mechanical force on actuator 14a or by fluid pressure at any of ports 16a, 103 or 104. As shown there are two pistons 101, 102 additional to piston 13a. Piston 13a is integral with sliding part 12a, as in Fig. 3, but pistons 101, 102 can slide relative to sliding part 12a so that as few pistons as possible are moved in response to a fluid input signal: e.g. fluid at port 103 moves piston 101 but not 102. The abutting faces 137-139 of the pistons have legs, Fig. 5 (not shown), to prevent vacuum coupling between the pistons.

Filed: 1923-08-13
Abstract: 223,689. Ormond, J. J. Aug. 13, 1923. Cylinder offset machines; set-off, preventing. - In travelling cylinder offset printing, the rotation of the offset roller is regulated by its soft surface contacting with a fixed guide rail or rails as it is moved over the printing-plates. In the machine shown in Figs. 3 and 4, the offset roller 5, carried forward on moving chains 20, rolls over inked printing- plates 2, 2<1>, 2<11>, each having part of a design or colour, and deposits the design on a surface on a plate 4. The plates are spaced apart a distance equal to the circumference of the roller 5, which receives its rotation by sagging into contact with guide rails 25, 26 level with the printing-plates. The shafts 10 of the sprocket wheels 12, 13 carrying the chains are mounted in adjustable bearings. When the roller 5 has been carried round as far as the bottom of the sprocket 13, it is rotated rapidly by belts 32 moving in the opposite direction, which belts bear on the ends of the roller. When spinning round this, the roller passes over a horizontal rotating disc 40, which clears off any ink from the roller surface. A cleaning solvent may be applied to the disc and its vertical shaft 41 is preferably hollow to receive the dirt scraped off by a scraper 42. After leaving the disc, the roller comes in contact with a broad wiper-belt 45 moving slowly in the same direction. This belt 45 is formed of thin textile fabric supported by thin steel and cleans and polishes the roller surface. When the roller reaches the sprocket 12 it is lifted off the belts and travels round until it mounts the curved ends of the fixed guide rails 25, 26 which stops it spinning and cause it to rotate in the opposite direction for printing as before. The printing-plates may be electrotypes, etched or engraved plates, lithographic or stereotype plates &c. Specification 223,690 is referred to.
