Title: Improvements in or relating to thermally-operated temperature-limiting devices
IPC: H01R13/713
Filed: 1934-02-23
Abstract: 432,053. Thermally-actuated valves. GREEN, G. E., and GREEN, Q. F., 7, Barston Road, Norwood, London. Feb. 23, 1934, No. 5919. [Class 135] [See also Group XXXVII] A temperature-limiting device adapted to eject a connector D from pins C or in other ways to break a circuit or operate a valve comprises a spring J which tends to press a tube H to the right and a ferrule K to the left. The tube H is normally held fast by a hole P in the tube engaging a pin F which is pressed upwards by a spring G immersed in an alloy of low melting point and the pin F also prevents the ferrule K from moving. When the alloy melts, the inclined edge of the ferrule K presses down the pin F releasing the tube H which pushes the connector D off its pins C. A spring L then returns the ferrule to its original position, the spring G returns the pin F, and the alloy solidifies. The tube H is then pushed back by hand, a slot in its left-hand end allowing it to reengage the pin F.

Abstract: 824,015. Multi-ply paper bags. BEMIS BROS. BAG CO. Feb. 21, 1957 [Sept. 28, 1956], No. 5947/57. Class 94(2). A multi-ply paper bag has transverse reinforeing bands interposed between the plies in the region of the closure folds to produce the effect of an additional ply in these areas. The bands may be of paper or of other material such as cloth. In making a three ply bag, a web 1 forming the inner ply is combined with the intermediate ply web 3 in passage round a roller 7, and the outer ply web 5 is combined with the other plies between rollers 9, 25. Each ply is slit and perforated in the usual manner to produce stepped end closures by elements 45, 53, 61. A web 65 of the reinforcing material is fed by rollers 67 to cutting elements 73 which cut off a band 63 as the web enters the point A of joining of the webs 1, 3. A band 63 is fed between webs 1, 3 at bag length intervals. In a similar manner a web 79 of reinforcing material supplies bands 77 which are fed between the webs 3 and 5 at bag length intervals. The bands 77 and 63 are arranged on opposite sides of the slits and perforations so as to form top and bottom reinforcements respectively. Adhesive applicators 97, 99, 107, 109 each apply transverse lines of glue spots to the webs so that each band is glued by two lines of spots 91a, 93a, 103a 105a and 91b, 93b, 103b 105b to both webs enclosing it, and the webs are glued to each other by lines of spots such as 95, 95a, 101, 101a, adjacent the slits and perforations. The bag lengths are torn from the multi-ply web and the end closures formed in the usual way. The bands preferably stop short of the longitudinal seam, as shown.

Title: Process of making fluorinated acyl fluorides
Inventor: BRICE THOMAS J
IPC: C07C51/58
Filed: 1957-02-22
Abstract: Fluorinated acyl fluorides are prepared by treating a perfluoroalkyldifluoromethyl or chloroperfluoroalkyldifluoromethyl compound containing 4 to 12 carbon atoms with a mixture of nitric oxide or nitrogen dioxide and bromine or chlorine at elevated temperature in the vapour phase.  The invention also includes omega-chloro-perfluoro-alkanoyl fluorides of the general formula Cl (CF2)nCOF where n is 3-11 and its carbonyl derivatives, e.g. acid and salts.  The -CF2H group may be oxidised to -COF by passing a gaseous mixture of the fluorinated starting compound, nitric oxide or nitrogen dioxide and chlorine or bromine through a tube maintained at a temperature of 500 DEG -650 DEG C.  Tubes of nickel, nickel alloy, stainless steel, mild steel or platinum may be used, reaction times of up to 30 seconds are found to be suitable.  The theoretical reactant ratios are 1 mole of nitric oxide or nitrogen dioxide and 0,5 mole of halogen per mole of fluorinated starting material but it is preferred to use ratios slightly in excess of these.  A mixture of nitric oxide and nitrogen dioxide may be used or the nitrogen compounds and halogens may be formed in situ by using nitrosyl or nitryl halides, e.g. NOCl, NOBr, NO2Cl, NO2Br.  The acyl fluorides may be recovered by fractionally distilling the condensed reaction products.  Examples describe the preparation of perfluoroheptanoyl fluoride o -chloroperfluorohexanoyl fluoride and o -chloroperfluoro-octanoyl fluoride and the corresponding acids. Specifications 686,678, 712,784, 718,318 and U.S.A. Specifications 2,551,573 and 2,658,928 are referred to.

Filed: 1924-03-10
Abstract: 235,287. Logan, H. H. March 10, 1924. Brakes; stopping automatically at end of run. -Automatic brake-operating means for hoists, of the kind in which the brakes are applied slowly in the event of overspeed and quickly in the event of overwinding, through the agency of a brake-operating member, released bv the de-energizing of an electric circuit and limited in its movement by an adjustable stop controlled by mechanism synchronized with the winding-gear, is characterized by an adjustable brake-operating member consisting of an armature or core which is held against the action of gravity by an electromagnet or solenoid and engages the adjustable stop directly on de-energization of the circuit. Thus the automatic opening of switch 17 releases the solenoid core 20, allowing the latter to fall by gravity and operate the brakes through the rod 24. During the normal run a stepped member 12 is in register with the adjustable stop 25 to limit the downward movement of the core, but in the event of overwinding, the member 12 is withdrawn gradually by cams 2 on the disc 1 geared to the drum, thus allowing the stop 25 to fall to a greater extent as the overwinding proceeds, to give a graduated harder application of the brakes. Specification 152,466 is referred to.
