Filed: 1923-02-23
Abstract: 199,682. Adlam, E. G., and Seton, G. N. Feb. 23, 1923. Bottling. - In machines for bottling liquids under pressure and of the type in which the filling-head is provided with a rotary plug-cock, the cock during filling is held tightly in its casing by means of the gas pressure in the reservoir or tank; separate pressure and return pressure equalizing tubes are used and the cock is provided with three diametral apertures aligning with through-way gas and liquid ports in the filling-head. The pipe E, Fig. 1, which establishes communication between the gas or air pressure space in the tank A and the bottle D to be filled, communicates by a port B<1> in the filling-head B and an elongated slot or port C<1> with a chamber C<2> in the head of the plug-cock C. The chamber C<2> communicates by an offset port C<3>, Fig. 2, a second port B<2> in the head, and a lateral port B<3> with an annular space F<2> between the liquid-discharge pipe F and a concentrically-arranged tube F<1>. The space F<2> is in open communication with the pipe F through one or more apertures F<3> therein, and the counter-pressure from the tank passes to the bottle through the pipe F and nozzle or extension F<4>. The space F<2> is also open through the lateral port B<3> with a port H<1> in the head communicating through a through-way port C<4> in the cock with the return pressure pipe H in the tank. On turning the cock, the bottle is first placed in communication with the gas space of the tank, then this communication is shut off and the liquid-discharge port C<5> in the cock and the pipe H are simultaneously opened to the bottle. In the event of a bottle breaking, a floating ball J, which is preferably a rubber-covered cork ball, closes the liquid port B<4>. The ball is normally held in position by an adjustable pronged holder- K mounted in a bridge-piece K<1> seated in the walls of a recess B<6> in the filling-head. A light spring C<6> normally holds the cock C in its casing in the head. The bottle is held against a rubber- or other gasket G in a recess in a cap G<1> removably secured to the lower end of the filling-head. Two caps G<1> are shown, one screwed to the head' and the other below it and having a ring or projections G<2> to bear against the upper gasket, to adapt the head to bottles of different sizes.

Abstract: 327,815. General Electric Co., Ltd., and Robson, R. Feb. 18, 1929. Skid brakes applied by running axle or wheel.-A track brake for vehicles which is adapted to clamp the vehicle to the track is applied by a clutch device driven by an axle or wheel of the vehicle. As applied to the bogie of a tower crane, the apparatus comprises a rail-engaging shoe 30 carried by a pair of links 12 pivoted to the bogie frame at 11 so as to move parallel to the rail. The shoe has a rectangular opening 34 through which passes a shaft 35 of triangular section arranged to rock on bearings on the frame members 10. The shaft 35 is secured to a liner 38 counterweighted at 39 and having pivoted thereto a rack 40 adapted for engagement with a pinion 41 driven through a friction clutch from the running wheel 8 of the bogie. The clutch comprises a pair of discs carried by the wheel 8 and between which is gripped by springs a third disc carried by the pinion 41. The pinion is freely mounted on an extension of the bush of the wheel 8, which may alsd carry a driving pinion. The rack 40 can be thrown into and out of engagement with the pinion 41 by means of a toggle 42, 43 connected to a fixed point 45, a link 46 and an operating rod 44. The link 46 carries a die working in a slot 49 in the rack 40. The rod 44 may be actuated by a solenoid arranged to be energized and de-energized respectively when current is cut off from and supplied to the travelling motor of the crane. Thus if it is desired to stop the crane, lowering of the rod 44 engages the rack 40 with the pinion 41, thereby rocking the lever 38 and shaft 35 in one direction or the other depending upon the rotational direction of the wheels, the shoe 30 being forced into engagement with the under surface of the rail flange 32 in either case.

Title: Sliver delivery control device for textile drawing frames or the like machines
Inventor: WELKER MANFRED
IPC: D01H13/04
Filed: 1956-02-23
Abstract: 818,593. Sliver control devices. SPINN-UND ZWIRNEREI MASCHINENBAU KARL-MARX-STADT VEB. Feb. 23, 1956, No. 5651/56. Class 120(3) In a sliver control device of the kind wherein each single strand is passed through a feeler before being formed into the sliver and delivered to a sliver can, displacement of a feeler as a result of a break or fault in one of the strands causes a sliver guide to move to a position in which the sliver is diverted from the sliver can. In the arrangement shown a guide 5 is mounted on a shaft which can pivot about its axis so that the guide can deliver sliver to either of a pair of cans 6 (Fig. 1). For this purpose an arm 10 is loosely mounted on the shaft 8 such that it can be rotated about 'the shaft 8 by a pin 9 in engagement with it and given a reciprocating movement by the shaft 28. From the arm 10 depends a coupling member 11, an abutment of which normally engages under the influence of a spring 29, a notch 21 in a second arm 12 which is fixed to the shaft 8. Thus movement of the shaft 28 normally rotates the shaft 8 and moves the guide 5 to one or other of the two cans 6. To the arms 12 are connected two tension springs 15 and 16 which tend to centralize the arm 12. On the occurrence of a fault in one of the slivers 3 a corresponding feeler 7 operates an electro-magnet 17 to cause an abutment 20 to engage the free end of the coupling member 11 and pivots it out of engagement with the notch 21 of arm 12 and thus permit the arm 12 to centralize under the action of the springs 15, 16 and thus position the guide 5 between the two cans 6 such that the faulty sliver is not fed into the cans.

Abstract: 1,048,292. Valves. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Feb. 12, 1964 [Feb. 12, 1963], No. 5863/64. Heading F2V. In a piston valve, e.g. to provide a safety cross-connection between the outgoing and return line of a closed hydraulic circuit, the piston closure 5 is displaceable in either direction from the neutral position, against a stack of cup springs 8 upon spring rod 12 which abuts the end of a spring cylinder 7 and spring abutment 11 threaded therein, by excess fluid pressure from pipe connections 1 or 2 to establish communication therebetween. Spring rod 12 is screwed into a bore of piston 6 and spring abutment 11 is threadedly engaged within spring cylinder 7 and together with hollow pin 15 is non-rotatably keyed to rod 12 whereby, upon rotation of pin 15 the spring rod 12 and abutment 11 are displaced to alter the tension of the springs. The differential pressures acting across the piston 5, and hence the effective spring tension, is reduced by cross-connecting each connection 1 and 2, via bores in the interior of the piston 5 and spring rod 12, to the various cavities associated with piston ends on the other side of the piston 5. The piston 5 is manually operable to move along rod 12 by non-rotatable engagement of a square end 18 with a hand wheel 20, the rod 12 being locked against rotation by a nut 17.

Title: Improvements in polymerisation of organo-siloxanes
IPC: C08K5/14
Filed: 1947-03-03
Abstract: Organo-siloxanes containing alkyl radicals of not more than four carbon atoms with or without phenyl radicals, the ratio of hydrocarbon radicals to silicon atoms being 1.75 : 2.25, and at least 75 mol. per cent of the silicon oxide units being of the formula RR1SiO, when R and R1 are both alkyl radicals, are polymerized by heating with tertiary butyl perbenzoate.  The products may be liquids, gels, or resinous or rubbery solids.  The amount of perbenzoate employed is preferably .01-10 per cent by weight of the siloxane.  The temperature is sufficiently above the decomposition temperature of the perbenzoate to produce reasonably rapid but controllable rate of reaction.  It is preferably between 125 DEG  and 200 DEG  C.  Unless foaming is desired the perbenzoate is added in successive small portions.  The reaction is preferably preformed in the absence of oxygen, e.g. under reduced pressure or in the presence of carbon dioxide.  Solid siloxanes may be dissolved in inert solvents boiling above the reaction temperature or may be milled with the perbenzoate.  The polymerization may be performed in stages, the first stage being accomplished, if desired, with the aid of benzoyl peroxide.  The second stage may be performed in a mould, if desired after admixture with a filler.  Alternatively, the filler may be incorporated before the first stage of the polymerization. Suitable fillers are iron oxide, glass, alumina, titania, carbon black or zinc oxide.  A table is given showing the change in viscosity produced in various siloxanes by treatment with various quantities of tert.-butyl perbenzoate for 18 hours at 150 DEG  C. Examples are also given of the treatment of dimethyl siloxanes. Other siloxanes mentioned are phenyl methyl; phenyl ethyl diethyl; propyl or butyl; siloxanes from mono- and di-methyl silicon compounds with an average ratio of methyl to silicon between 1.75 and 2, or from di-and tri-methyl silicon compounds with a ratio between 2 and 2.25.  The rubber-like polymers of the invention may be milled with a filler and a vulcanizing agent and laminated with one or more layers of an inorganic fabric, e.g. glass fabric, or felted glass fibres, or asbestos fabric.  Resistance wire may be included in the inorganic fabric or one of the lamin  may be of resistance wire cloth to make a heating pad.  For a pressure-sensitive electrician's tape a glass fabric may be provided with a single coating of vulcanized elastomeric siloxane in a tacky state.  Heating the tape after application completes vulcanization in situ.  Specification 630,883 is referred to.
