Title: Boron hydride carbonyl compounds and their preparation
Inventor: KNOTH WALTER HENRY
IPC: C07F5/02
Filed: 1963-06-25
Abstract: The invention comprises compounds of the formula B10H8-mXm(CO)2, where X is halogen and m is a cardinal number of from 0 to 8 inclusive.  The compounds may be made by reacting a compound of the formula B10H8(CO)2 with a halogenating agent, such as chlorine, bromine, iodine, BrCl, ICl and N-halosuccinimides. The compound B10H8(CO)2 is made by reacting carbon monoxide with the bis-diazonium compound B10H8(N2)2.  Preferably an excess of CO is used at temperatures above 100 DEG  C., more preferably 125-250 DEG  C. and pressures above 200 atm., e.g. 500-1000 atm. Detailed examples are given.  Specifications 956,392 and 985,107 are referred to.ALSO:The invention comprises compounds of the formula B10H8- mnXmRn(CO)2 wherein X is halogen, R is hydrocarbyl of up to 18 carbon atoms free of aliphatic unsaturation, m is a whole number of from 0 to 8, inclusive, n is 0, 1 or 2 and the sum of m+n is at most 8.  The novel compounds in which m and n are both at least 1 may be made by reacting B10H8- nRn(CO)2 with a halogenating agent, e.g. chlorine, bromine or iodine, BrCl, ICl and N-halo-succinimides.  The starting materials are made by reacting carbon monoxide with the bisdiazonium compound B10H8(N2)2 in the presence of a hydrocarbon or a mixture of hydrocarbons.  The carbonyls B10H8- mnXm Rn(CO)2 on treatment with reducing agents such as lithium aluminium hydride followed by decomposition with water are converted to acids (H3O)2B10H8- mnXmRn (CH3)2 which form metal salts, complex metal salts, ammonium salts, hydrocarbyl-substituted ammonium salts, phosphonium salts and sulphonium salts.  The carbonyls react with water, or aqueous alkali followed by acidification, to give dicarboxylic acids (H3O)2B10H8- mnXmRn (COOH)2.  These acids form salts containing the anion [B10H8-m-n XmRn(COOH)2] or [B10H8-m-nXmRn (COO)2]4- with cations of the type described above.  These tetrabasic acids and their salts may also be made by halogenation of acids (H3O)2B10 H8- nRn(COOH)2 and their salts.  Many detailed examples are given.  Specifications 956,392 and 985,707 are referred to.

Abstract: 673,476. Feeding can covers. CONTINENTAL CAN CO., Inc. Sept. 30, 1949 [Jan. 24, 1949], No. 25258/49. Class 125 (ii). In the high speed feeding of can covers to transfer means associating them with the cans to be covered, a stack of covers is supported by a number of continuously rotating feeder screws, which feed them one by one from the bottom of the stack, means, comprising projectable lugs, taking over the support of the stack and allowing the screws to continue. rotating when a break in the continuity of the can feed occurs. A stack of covers 92 is supported on ledges 86 of feeder screws 68 within the well 6 of a housing 5, the bottom cover being detached by the sharp end point 91 of the feeder groove 78 in each screw and forced down on to rails for conveyance to a can, any rebound being prevented by the flat bottom surface 82 of the screw. The next lowermost cover has meantime ridden down a slope 88 on the top plate 83 of the screw on to the ledges 86. Should the can feed be interrupted, a lever 42, Fig. 1, normally engaged by incoming. cans 43, is moved downwardly with lever 40, by a spring 44 so as to rock a shaft 36, thereby moving a roller 34 within a slot of an extension of an actuating ring 30 so as to operate the pivotally mounted cover supporting lugs 25. This is effected by pins 29 depending from the ring and received in slide blocks 28 moving within the forked end of the lugs which are thereby caused to pivot inwardly into the well at the level of the top surface of the feeder screws and support the cover stack whilst the screws continue to rotate. On retraction of the lugs by resumption of the can feed a cover is conveyed by one revolution of the screws. Specification 673,475, [Group XXII], is referred to.

Abstract: 716,384. Seaming veneers. FRIZ GES., A. Oct 31, 1951 [Nov. 1, 1950). No. 25465/51. Class 42 (1) A veneer joint-gluing machine in which the veneers to be glued are fed together is characterized in that the upper press member is connected to the lower press member by means of a vertical web arranged parallel to the direction of feed of the veneers between the edges of the veneers which are not in contact with one another. The upper press member consists of members connected in line together along the direction of the joint, the members being adjustable for height, and so arranged that transverse movement of the upper-pressure device is impossible. The web is provided with guide grooves so arranged that the veneers are fed in in different planes and are thus moved into a common plane. The veneers are placed on tables 10, 11 and fed by the rollers 20, 21, the top pair being spring-loaded as shown, towards the gluing devices 32 of known construction. The veneers are thus brought into a common plane and pass between the pairs of rollers 4 and the conveyer belt 6 the rollers of each pair being skewed together to cause the veneers to exert pressure on one another. The web 13 has grooves 14, 15 to guide and align the veneers. the web supporting the arm 22. This arm is pivoted at 24 to the top press member and prevents lateral movement thereof. The arm may be resilient and a spring 29 and compression screw 28 are provided to regulate the press pressure. Several such pressure-regulating devices can be provided along the upper press member and thus the pressure exerted by it may vary along its length. The joint may be heated electrically.

Title: Data modem having line verification features
IPC: H04B3/20
Filed: 1974-06-11
Abstract: 1478655 Telephone exchanges MILGO ELECTRONIC CORP 11 June 1974 [31 Jan 1974] 25794/74 Heading H4K In an arrangement for transmitting data over a direct distance dialled telephone network, a data modem is adopted for single frequency band, two-wire half-duplex operation and includes means adapted to operate independently of its data transmitting and receiving circuitry to transmit a first tone of a standard frequency such that it instructs any echo suppressors in the already set up path to be disabled and means responsive to an acknowledgment tone returned from the other modem involved to indicate that a path to the other modem has been established with echo suppressors disabled. As described the subscriber stations A and B are respectively connected to their local exchanges via a two wire line 105. The exchanges are interconnected via a four wire trunk circuit 140 and hybrids 50 and 70. To establish a data connection a speech connection is first set up, contacts 124 and 173 are closed to maintain the connection by earthing a line wire and the handsets are replaced. Two embodiments are described. In one, one station is a master station and transmits a standard 2025 Hz tone to which the exchange responds switching out the echo suppressors in the trunk network. The tone is received at the slave station which returns a second tone and enables its data modem. The second tone is outside the speech band and tests that the suppressors have been switched out and that the path is of suitable quality. The master station detects this tone and enables its data modem. In a second embodiment the two stations are equal. Each alternately transmits and listens for the standard tone. As the two stations are asynchronous the two stations drift until one picks up the standard tone from the other and switches to the responding mode. The modems include automatic disconnect circuits which release the line when data transmission is absent for a predetermined period.

Title: A process for the production of unsaturated halogen-containing derivatives of propene
IPC: C07C17/25
Filed: 1938-09-07
Abstract: 518,325. Halogenated hydrocarbons. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Sept. 7, 1938, No. 26194. Convention date, Sept. 14, 1937. [Class 2 (iii)] Unsaturated halogen-containing derivatives of propene are produced by subjecting the vapours of a polyhalogen propane capable of splitting off hydrogen halide, to a temperature above 450‹C., preferably for a length of time sufficient to dehydrohalogenate not more than about 40 per cent. of the polyhalogen propane. The polyhalogen propane may be passed through a tube, e.g.'of glass, quartz, carbon or steel, unpacked or packed with pumice, carbon chips, glass wool, porcelain or clay chips, maintained at the desired temperature. The use of dehydrohalogenation catalysts, e.g. calcium or barium chlorides, as tube packing is referred to but possesses no advantages over the above. In the example propylene chloride is vaporized and passed through a KA steel or quartz tube at 510‹C., and the product condensed and fractionated to yield allyl chloride, alpha- and #-chloropropylene and unchanged propylene chloride. Small amounts of allene and allylene are also formed in this reaction. The reaction may proceed in the presence of an inert gas, e.g. nitrogen or carbon dioxide. Other starting materials specified are 1.1.2-, 1.2.2.- and 1.2.3- trichlorpropane.
