Title: An improved manufacture of hydrocarbon copolymers
Filed: 1944-11-14
Abstract: Hydrocarbon copolymers are prepared by copolymerizing an aromatic monoolefin and an aliphatic monoolefin, the aromatic monoolefin comprising from 30 to 45 per cent by weight of the mixed olefines in the presence of a Friedel-Crafts catalyst at a temperature below -70 DEG  C.  Specified aromatic olefins are styrene and its homologues, indene and terpene and specified aliphatic olefins are isobutylene and isopentene.  The copolymerization is preferably carried out at between -70 DEG  and -105 DEG  C. in the presence of methyl or ethyl chloride as a solvent and/or diluent. The catalyst may be boron fluoride, aluminium chloride, aluminium bromide, or titanium chloride preferably in solution in methyl or ethyl chloride.  The resulting copolymers have an intrinsic viscosity greater than 0.6 and are all soluble in non-aromatic solvents such as aliphatic or naphthenic hydrocarbons preferably having a boiling point above 10 DEG  C., e.g. petroleum naphtha, petroleum ether, gasoline, octane, myrcene and kerosene.  These solutions are particularly useful for forming protective films on such surfaces as metal, wood, paper and cloth, while self-supporting films may be produced by stripping off the film-a stripping agent such as polysilicone may be used. Specification 543,308 is referred to.

Title: Improvements in or relating to typecasting or typecasting and composing machines
IPC: B41B7/04
Filed: 1930-07-26
Abstract: 350,311. Type-making machines. ELLIOTT, R. C. and LANSTON MONOTYPE CORPORATION, Ltd., 43, Fetter Lane, London. July 26, 1930, No. 22557. [Class 100 (iii).] Single-type composing and casting machines.-Relates to means for positioning an additional row of matrices in one or both directions of movement of the die-case in machines such as that described in Specification 8633/99, [Class 100, Printing, Letterpress &c.]. The end pin B<15>, Fig. 1, of one series B<1> of positioning-pins, which is normally fixed, is made retractable, so that the die-case can move one step farther. The pin B<15> is held projected by air led to it by a pipe e<1> from a constant supply e<2>, and the supply can be cut off by valve mechanism under the control of a special signal in the record strip, whereupon the pin drops, or is retracted by a spring. The valve mechanism comprises a casing E, Fig. 3, containing a piston E<1> and a valve E<2>. The constant air supply to the pin B<15> enters the casing by a conduit e, and leaves by a conduit e<3>. The special signal controls two ports c, c<1>, Fig. 1, in the air-bar C, from which pipes e<5>, e<10> lead to the valve casing, and thence to pins B<11>, B<13> in the second series B of positioning- pins, which are normally operated by the components of the signal. Air reaching the valve casing from the port C<1> passes by a branch conduit e<7> into the bottom of the casing below the piston E<1>, which is thereby raised, and lifts the valve E<2>. If air at the same time passes from the port c to the valve casing, this air passes below the valve, which is raised farther. The conduits leading to the pins B", B<13>, B<15> are thereby closed, so that the pins B<11>, B<13> are not operated, and the pin B<15> is withdrawn. The device may be duplicated, so as to act upon the end positioning-pin of the other series. Specifications 6331/10 and 227,144, [both in Class 100 (iii), Typemaking &c.], also are referred to.

Sept. 10, 1925 Variable-speed and reversing gearing may, according to a Pro, visional Specification, be constructed of epicyclic friction gear trains which each comprise an inner or outer resilient race member such as C. Presser devices act on this race member to vary the contact pressure upon the transmitting parts proportionally to the torque. The race C may comprise rings side-by-side and split at C'. C<2>. Fig. 2, or may be in the form of a helix. One presser device comprises pairs of rollers K, separated by springs K<1> adapted to become wedged between flats W on a head J and the inner surface of the race C, which is thus expanded uniformly during power transmission. For heavy duty. the flats may be replaced by suitably curved surfaces. Initial contact pressure independent of the drive is obtained by a pair of presser conical discs L<1>, O, Fig. 1. thrust towards each other by a spring M surrounding the high-speed shaft H. The head J is fast on the shaft H. A low-speed shaft G carries the planetary transmitting rollers D in a suitable cage F. The ends of the rollers D may be supported in the cage by being journaled in spaced bushes, or journaled in blocks slidable radially in guides. In the arrangement shown, it is the outer race B that is fixed.

Class 110 (3) In a gas turbine plant for utilizing solid waterbearing fuel such as bagasse, sewage sludge coal slurry, sulphite pulp mill waste, town refuse or peat, comprising a drier and separator in which at least a part of the water content of the fuel is evaporated and separated from the solid content, a combustion chamber receiving the solid content of the fuel from the drier, a turbine and a turbine exhaust gas heat exchanger, at least a part of the water content of the fuel evaporated in the drier is passed through the heat exchanger before being passed with the combustion gases through the turbine. The compressor 1 driven by the turbine 3 supplies air to the combustion chamber 4 which feeds the turbine. Part of the combustion gases are led off at 4a and recirculated into the fuel drier 5 to which the solid fuel is fed through an inlet 6. The mixture of solid fuel, recirculated gas and steam from the drier 5 is led to a separator 7 where the solid fuel is separated out and led, together with a small part of the gases and steam directly to the combustion chamber 4. The greater part of the gaseous constituents are led through the heat exchanger 8 and pass into the combustion chamber 4 where they cool the walls and then mix with the combustion gases. A byepass 10 connecting the outlet of the heat exchanger 8 to the fuel drier 5 is provided so that the mass flow through the heat exchanger may be increased so as to increase its heat transfer rate. The plant is designed so as to give the recirculated gases a temperature corresponding to the dew point at the entry to the heat exchanger. The fuel supply to the drier may be partially dried as described in Specification 666,692. The recirculated gases may be led into the primary combustion zone of the combustion chamber or into the duct between the combustion chamber outlet and turbine inlet.

Abstract: 1,263,238. Torque wrenches and screwdrivers. GARDNER-DENVER CO. 11 May, 1970 [28 Nov., 1969], No. 22696/70. Heading B3N. A power torque tool has an air motor 14, a rod 112 actuating a shut-off valve 32 for the motor 14 and a torque sensing, rotation transmitting means 70 including driving and driven members 72, 80 which are adapted to move relatively to each other upon sensing a predetermined torque and gripping means (balls 108) operable to grip rod 112 but to release it at the predetermined torque. The pressure fluid motor 14 drives the driving member 72 through an epicyclic gearing 24. Member 72 drives member 80 which in turn drives a spindle 54 by balls 84. The operation of the gripping balls 108 are urged to friction grip rod 12 by a conical surface 106 formed on member 80. In operation, downward pressure on the tool will move bit 56, spindle 54 and torque sensing means 70 axially toward motor 14 against a spring 116. The balls 108 are forced to grip member 112 and move it axially to operate valve closure member 36 to open valve 32 thus starting the motor. The closure member is biased shut by fluid pressure in supply passage 30. The interengaging driving surfaces between members 72 and 80 are sloped and urged into contact by spring 102, limited axial movement being allowed so that as a predetermined torque is reached member 80 is forced away from member 72 whereby the gripping force of balls 108 is released and valve closure member 36 is forced by fluid pressure to shut the valve. Spring 116 repositions torque sensing means 70 to the position shown in Fig. 1. In a modification a manually controlled throttle valve is positioned up-stream of valve 32 which in this case is spring-biased open. After release of actuating member 112 to close valve 32 and shut off the motor, the throttle valve is released and vents pressure fluid from upstream of the shut-off valve which is thus opened by the spring pressure. An electric motor may be utilized whereby actuating member 112 operates a spring-biased switch to cut-off motive energy to the motor.

Abstract: 224,991. English Electric Co., Ltd., and Zweigbergk. T. Sept. 11, 1923. Switches, partly electromagnetic.-Remote selective control of switch gear for example, the reverser forming part of an electric traction equipment comprises an intermediate member between the actuating member and the switch member, which is selectively positioned from a distance so that the actuating member has been effected, positively drives the switch member in the selected direction. As shown, applied to a reverser, the switch shaft 13 is rocked in one direction or the other by the thrust imparted to an intermediate member 1 by a motor-driven cam wheel 2. The intermediate member is pivoted on a lever 3 which by means of a roller 6 engages the cam wheel under the action of the weight 7. The free end of the intermediate member may be brought into engagement with either of two rollers 31, 32 pivoted on a sector 30 attached to the shaft. The selection is made by energization through the drivers train reversing switch of one or other of the solenoids 22, 23 which attract the armatures 17, 21 draw the sliding rod 18 to left or right. The rod acts through the lever 24 on the setting link 10 pivoted at 11 to the intermediate member. To change the reverser over from the position shown the solenoid 23 is deenergized and 22 energized so that the rod 18 tends to move to the left. Such movement is prevented, however, by a cam formation 12 on the reverser shaft which prevents movement of the intermediate member. The actuating motor for the reversing switch can only be energized after the line breaker 39, Fig. 4, has been placed in circuit by the switch arm 27 carried by the rod 18 engaging one or other of the fixed contacts 28 or 29 at the ends of its stroke. The circuit of coil 22 or 23 of the setting device is completed by the contact 42 or 41 respectively of the drivers reversing switch 38 when the controller 37 is moved from its off position to bridge contacts 40. Thus the setting of the intermediate, member 1 takes place before the motor commences to drive the cam 2 to produce the actuating operation.
