Title: Process for the manufacture of moulded bodies
IPC: C08F265/06
Filed: 1960-08-25
Abstract: 65 parts by weight of a polymer having a K-value of 50-60 and a bulk volume of 7-8 are mixed with 35 parts by weight of monomeric methyl methacrylate.  In the example given the polymer contains 95 parts by weight of methyl methacrylate, 2 parts of methyl acrylate and 3 parts of butyl acrylate, and in the monomer is dissolved 0,5 parts by weight of an accelerator, e.g. dimethylaniline or a sulphinic acid. The paste is inserted in a mould the walls of which are painted with a solution containing 50 parts by weight of benzoyl peroxide and 50 parts by weight of benzene.  Other higher esters of acrylic acid and/or methacrylic acid may be used as monomers for the copolymerization with the methyl methacrylate.ALSO:A process for the manufacture of moulded bodies e.g. dental prostheses, uses as a raw material a pasty mixture of about 65 parts by weight of a polymer e.g. methyl methacrylate and 35 parts by weight of a monomer, which has been filled into collapsible tubes.  The polymer has a K-value of 50-60 and a bulk volume of 7-8.  The mixture may incorporate as an accelerator either dimethylaniline, sulphuric acid or a tertiary amine.  The walls of the mould are coated with an actuator (benzoyl peroxide, lauroyl peroxide or 2-4 dichlorobenzoyl peroxide) dissolved in a volatile solvent, prior to the insertion of the mixture into the mould.

Abstract: 252,995. Miller, A. W. Nov. 25, 1925. Golf clubs. -A golf club head is provided with a longitudinally - extending bore, a weight disposed within the bore, a member extending laterally into the bore from one face of the club and engaged with the weight, and means for moving the weight into and maintaining it in clamped position with the member. As shown, the weight 11 has a central recess with an inclined face 13 against which the globular head 16 of a pin 15 is adapted to bear. The globular head is introduced through a key-hole slit 14 in the weight. The outer end of the pin is formed as a plate 17 which may be situated on the upper surface of the head as shown or may constitute a striking-face or a sole plate. A screw 21 passing freely through a bush 22 screws into the weight and abuts against the globular head 16. By tightening-up the screw a wedging action takes place between the inclined surface 13 and the globular head thus locking the weight in position. The balance of the club may be adjusted by cutting off a portion of the metal from one end or the other of the weight.

Abstract: 1436253 Feeding sliver to spinning machines TOYODA JIDSHOKKI SEISAKUSHO KK 26 June 1973 [7 May 1973] 30329/73 Headings D1D, D1F and D1N In a spinning machine sliver is delivered to each spinning unit through a guide conduit which is of larger diameter than the sliver and having a generally upright portion 5b and transverse lower end portion 5f, the sliver being intermittently taken up from a can 3 by a take up means 7, 15 disposed above the guide conduit into which it feeds the sliver at an instantaneous rate which is greater than the rate at which the sliver is continuously withdrawn from the bottom of the conduit, hence causing a build up of sliver in the conduit. A resiliently loaded flap 5e may be provided on the transverse portion of the conduit or the transverse portion may be shallowly inclined and may also be turnable, Fig. 3B (not shown). The intermittent take up of sliver may be achieved by delivering the same over a constantly driven grooved roller 7 such that when tension on the downstream side is relaxed by a build up of sliver in the conduit 5 slip ocours. Alternatively a feed roller 15 may be associated with a resiliently positioned pressure roller 16 which can be disengaged by a solenoid 19 on receipt of a signal, from a photosensor in the conduit, which is activated when the conduit is full. The conduit may have a sinuous path for the sliver therein formed by a tubular insert or by triangular internal projections. Alternatively a circular section conduit may have annular constructions. Conduits for adjacent spinning stations may be provided by subdivision of the space between wall members extending along the machine.

Filed: 1920-10-28
Abstract: 171,297. Finlay, R. F. Oct. 28. 1920. Combined fluid-actuated and mechanical gears. -Single or double-acting motors for reciprocating conveyers are provided with cylindrical slidevalves arranged in the cylinder upper covers and moved in one direction by fluid-pressure and in the other by the pistons and fluid-pressure acting consecutively. In the position shown in Fig. 1, fluid from the supply 1 passes to the cylinder by passage 4. When the piston passes one of the ports 6 - - 9, the operative port being determined by a helically-grooved, adjustable rotary valve carrying a pointer, fluid passes through the corresponding port in the valve 11 to the upper end of the valve 3. The main piston 5 and valve 3 are reversed. During the upstroke, the piston engages a projection 15 on the valve the motion of which is completed by the incoming fluid. The arrangement of the ports 16, 17 ensures cushioning of the piston and valve respectively. In a modification, a rotatable valve in the cylinder forward passage permits single or double action.

Title: Improvements in and relating to the production of mixtures of aromatic hydrocarbons
IPC: C07C2/78
Filed: 1946-10-12
Abstract: Aromatic hydrocarbons are prepared from a hydrocarbon gas containing at least 20 per cent by volume of methane by mixing therewith at 0-400 DEG  C. and under pressure, the volume of an oxygen-containing gas equivalent to a partial pressure of oxygen which is 0.25 to 0.28 of the partial pressure of methane present in the mixture, and effecting an incomplete combustion by spark ignition and explosion. The aromatics may be separated by absorption or adsorption in oil, silica gel or active charcoal. One or more autoclaves fitted with sparking-plugs may be used, advantageously connected in series so as to be filled, ignited and freed from reaction product in cyclic succession.  Filling may be effected by one or more compressors or blowers.  Thus, a single compressor or blower may deliver methane-containing gas to a definite pressure and then be reversed to suck oxygen and deliver this until the final pressure is reached.  In an example, methane of 93 per cent is introduced into an autoclave until an excess pressure of 12 atmos. is reached, oxygen then being introduced to a final excess pressure of 15.1 atmos.  Ignition is effected by a spark discharge, voltage 120, current about 50 amps. When the oxygen pressure is reduced below 2.8 kgs./sq. cm., no ignition occurs, while above 3.3 kgs./sq. cm. no aromatics are formed.

Abstract: 484,604. Massage appliances; tourniquets. U.M.A., Inc. Nov. 9, 1936, No. 30528. Convention date, Nov. 7, 1935. [Class 81 (ii)] [Also in Group XXVIII] An apparatus for increasing blood circulation through an extremity by intermittent occlusion of the venous circulation comprises a pneumatic cuff' for encircling the part, and means for inflating the cuff to a pressure intermediate between that of the venous and arterial circulation, said means being automatically controlled so that the cuff is repeatedly inflated, held at the given pressure for a short period, deflated to atmospheric pressure and so retained for another short period. A cuff 1 of usual design has a port 2 connected to an air compressor 6, driven by a motor 7 and to a release valve 21, 22 operated by an arm 30 of a relay armature 31, 32. The armature is moved into pressure-releasing position by an electromagnet 40 energized by a circuit including a switch 44, the actuating member 50 of which when moved to close the circuit acts through an extension 51 mechanically to open the release valve. The circuit of the electromagnet 40 is energized from a source of alternating current through leads 45, 61, the lead 61 having a contact 62 which bears on rotating metallic disc 63 on which is mounted a disc 65 of insulating material having spaced gaps. A contact 64 connected to the electromagnet bears on the gapped portion of the insulating disc so that as this rotates the circuit is alternately made and broken. The discs are rotated conveniently by a synchronous motor 67 or a clockwork motor. The circuit of the motor 7 is controlled by the rotating disc through a magnetic relay 81, 82 in the required relationship with the release valve and is further controlled by a mercury pressure gauge 92 into which dip contact wires 91, 93 connected to the circuit. The wire 91 is adjustable so as to vary the pressure in the tube 97 (and the cuff of the device) which is reached before the mercury column leaves the wire 91 and breaks the circuit of the motor 7 and stops the pump. Indicator lamps 103- 105 are provided in the circuit.
