Abstract: 248,366. Waggon-und Maschinenbau Akt.-Ges. G÷rlitz. Feb. 28, 1925, [Convention date]. Feeding webs.-In arparatus lor guiding fabric webs in which a feeler engaging the selvage controls pressure-fluid means for adjusting the guides, the supply of pressure fluid to the guide-adjusting mean is controlled by a rotary slide valve directly connected to the feeler and having longitudinal grooves co-operating with fluid inlet and outlet apertures constructed as longitudinal slots in the valve casing. The guiding device is of the known construction comprising an arm 2, Fig. 2, at each side of the fabric carrying a chain provided with clips to grip the selvage, and movable laterally in accordance with lateral movements of the web by the rotation in either direction of a screw 1 operated by means controlled by a feeler 22. The shaft 1 carries a friction wheel 3 adapted to be engaged by either of two friction wheels 5, 6, Fig. 1, constantly driven in opposite directions, and mounted on a swing frame 4 on which is mounted a cylinder 8 movable on a stationary piston 7. Hollow piston rods 13, 14 having apertures 15, 16 communicating with the interior of the cylinder are connected by pipes 19, 20, Fig. 1 and 3, with longitudinal slots 33, 36, Figs. 3 and 5, in the sleeves 27, 27<1> respectively forming a casing for a rotary slide valve 23 to which the feeler 22 is directly attached. The valve is provided with a longitudinal groove 30, in constant communication with a pressure inlet pipe 24, and with grooves 31, 32 in communication with the atmosphere through passages 35. 34 in the sleeves 27, 27<1> respectively, and passages 25, 26 in the outer casing 21. When the valve is turned in either direction the groove 30 communicates with one of the pipes 19 or 20 and the other pipe is opened to the exhaust. Owing to the formation of the passages 30, 33, and 36 as longitudinal grooves, a large area is at once opened for the flow of pressure fluid and a rapid engagement of the appropriate wheels 5, 6 with the wheel 3 is obtained. The sleeve 27<1> is adjustable angularly relatively to the sleeve 27 by means of a handle 28 so that the distance between the slots 33, 36 may be varied. By this means, the amount of deviation of the web which can take place without actuating the guides may be controlled.

Title: Improvements in Circuit Breakers.
IPC: H01H73/38
Filed: 1918-03-26
Abstract: 121,059. Igranic Electric Co., (Cutler- Hammer Manufacturing Co.). March 26, 1918. Automatic circuit-breakers have two contacts, the upper one of which is carried by an arm 2 and normally is manually operated by a handle 11 to open and close the circuit, the lower one 3 resiliently and preferably insulatedly carried by an arm 1 which tends by gravity or spring action to move to open the circuit, but is restrained from doing so by a spring-controlled catch 5 engaging a pin 23 on the pivoted arm. When an overload occurs, the catch 5 is released by a solenoid 6 operated by an overload tripping coil, and the arm 1 moves to open position. To reset the circuit-breaker, the arm 2 is first raised to open position, and the arm 1 is at the same time moved to closed position by means of a link 12 with a slotted end which acts on a pin 15 towards the end of the motion of arm 11. The arm 1 is then again held by the catch 5, but only if the overload has ceased. The circuit is completed by returning the arm 11 to closed position. The arm 11 is so formed that its weight holds the contact 4 by gravity in either of its extreme positions. The whole arrangement is mounted on a panel 8, and stops 18, 21 limit the movements of the arms 1, 2.

Patent GB-918500-A (GB)
Title: Preparation of higher boron compounds and alcohol derivatives therefrom
IPC: C07F5/04
Filed: 1961-02-14
Abstract: Alkanols are made by mixing an olefin and a boron compound of the formula <FORM:0918500/IV (b)/1> wherein R is an alkyl radical containing from 1 to 6 carbon atoms and R1 and R11 are identical or different alkoxy radicals containing from 1 to 6 carbon atoms, or alkyl radicals containing from 1 to 6 carbon atoms, or hydrogen or a halogen atom, maintaining the resulting mixture at a temperature between 50 DEG  and 350 DEG C. at superatmospheric pressure in the presence of a free radical source to produce an alkyl borate ester, and converting the said ester to an alkanol by reaction with water or an alcohol boiling lower than the product alcohol.  The free radical source may be an unstable organic compound yielding free radicals such as a peroxidic initiator or azo-bis-nitrile but other sources, e.g. ionizing radiation from a Cobalt-60 source, a Van de Graff generator or an atomic pile, are mentioned.  Suitable boron compounds are trimethyl borate and other trialkyl borates having alkyl groups of 1-6 carbon atoms, propoxy diethyl boron, butoxymethylhydrogen boron and dimethoxy boron chloride.  The olefin is preferably a gaseous olefin such as ethylene.  The telomerization is preferably effected at temperatures between 125 DEG  and 250 DEG C. and at pressures between 10 and 2000 p.s.i.g.  A typical reaction between trimethyl borate and ethylene produces an ester RO.B(OR1)OR11 where R, R1 and R11 are alkyl groups of the formula -(C2H4)nCH3 where n is an integer in the range 0 to 20, with the proviso that at least one of the three alkyl groups contains at least three carbon atoms.  The borate ester may be converted to an alkanol of the formula CH3(C2H4)nOH.  Thus the alkyl borate-containing reaction mixture is passed to a distillation zone wherein trimethyl borate and hydrocarbons having boiling points up to that of the desired alkanol are removed, the remaining liquid alkyl borate is passed to a generation zone wherein it is heated with at least 3 mols of methanol per mol of alkyl borate and trimethyl borate and free alkanol are separated from the mixture.  The trimethyl borate recovered from the distillation and generation zones is purified and recycled to the reaction zone.
