Title: Improvements in or relating to the manufacture of plastic masses containing rubber
IPC: C08L7/00
Filed: 1934-04-13
Abstract: Plastic masses are prepared by condensing a phenol or a homologue thereof with an aldehyde in the presence of an aqueous dispersion of rubber so as to effect simultaneously coagulation of the dispersion and formation of the resin.  The aqueous dispersion of rubber may be natural rubber latex or an artificially produced dispersion of natural or synthetic rubber.  The phenol and the aldehyde may be added separately to the dispersion or previously mixed and then added to the dispersion and the mixture heated.  In an example, a mixture of an aqueous solution of phenol and aqueous formaldehyde is added to ammonia stabilized rubber latex and the whole mixture is heated in an autoclave.  The dried mass is mixed with stearic acid, zinc oxide, mercaptobenzothiazole and sulphur and worked up by the usual processes of the rubber industry. Other vulcanizing agents, anti-oxidants, accelerators, or softeners may be used in the composition.ALSO:Plastic masses are prepared by condensing a phenol and a homologue thereof with an aldehyde in the presence of an aqueous dispersion of rubber so as to effect simultaneously coagulation of the dispersion and formation of the resin.

Title: Improvements in record card controlled machines
Filed: 1954-04-21
Abstract: 757,253. Ratchet gearing. MAUL, M. April 21 1954 [April 24, 1953]. No. 11513/54. Addition to 709,155 [Group XIX]. Class 80(3) [Also in Groups XVI and XIX] An overrun-proof clutch device comprises a driving member 14 oscillated different amounts to set type-wheels of a printing mechanism or accumulator wheels in statistical apparatus, a clutching pawl 18, a uni-directionally driven member, e.g. a toothed shaft 15, and a yieldable safety spring arrangement 34 with which the pawl 18 coacts to counter the overrun forces arising in the driven member 15. To operate the clutch a member 22 is actuated to press the pawl 18 against the driven shaft 15 so that when the driving member 14. rotated from a variably oscillated shaft rotates counter clockwise a pin 21 thereon moves downwardly in a slot 23 in the pawl 18 which is then moved into engagement with a tooth of the driven shaft 15. As soon as the type wheel has made the required selective rotation, the driving member 14 halts prior to a return oscillation but any overrun force, P5, Fig. 5, causes the driven member 15 to pivot the pawl 18 clockwise about pin 21 and engage a pin 25 of the spring arrangement 34. The face P12 of the spring is chosen so that the greatest overrun force P5 which arises will not be sufficient to depress the pin 25 so no unclutching is possible. Upon backward movement of the driving member 14 the force P5 is increased as the spring 34 yields and pawl 18 works clockwise and slides back to original position relative to the pin 21. The type wheels are prevented from reverse travel by an arrangement 31-33.

Abstract: 726,601. Type-bar-making machines. TELETYPESETTER CORPORATION. April 28, 1953 [July 18, 1952], No. 11705/53. Class 100 (3). Driving-mechanism.-In a mechanism for controlling the operation of a line casting and composing machine by means of recorded signals, utilizing selectable elements co-operating with code bars which are variably set in dependence on the signals, so that a particular element is selected by the code bars for each signal, the selectable elements are movable into and out of engagement with the code bars under the control of a bail member to which a reciprocating motion is imparted by a toggle device, the mechanism being so arranged that when the bail member is moved in one direction to bring the selectable elements into engagement with the code bars, a selected element is brought into operative engagement with an associated interponent member, and when the bail member is moved in the opposite direction, its motion is conveyed through the selected element and the interponent member to a corresponding actuator member which serves to actuate the appropriate key-lever or equivalent operating member of the machine. The code bars 44 are-set as described in Specification 415,798, and they have notches in their upper edges, which co-operate with leftwardly and rightwardly offset projections on selectable members 38 pivoted at 84. A bail member 86 carried on arms 87 pivoted at 84 engages near their free ends the elements 38. When a toggle 88, 89 is collapsed by an eccentric 96, the bail member is lowered and allows a spring 85 to move a selected element 38 downwards, which further allows a spring 98 to move a corresponding interponent member 37 to the right so that a shoulder 100 thereof overlies the end of the element 38. When the toggle is straightened, the bail rises, restores the element 38 and through it and the member 37 operates the actuator member 35, which actuates the requisite key-lever as described in Specification 415,798. The toggle is moved slightly past dead-centre, and a stripper bar 97 carried thereon moves the member 37 to the left to clear its shoulder 100 from the element 38.

Convention date, April 25, 1931. [Classes 38 (iii) and 38 (v).] In apparatus for drying the hair or body comprising an electric fan for generating a stream of gas a device, which may be present to operate during a predetermined period, is provided to rotate the arm of a rheostat or its equivalent to cut out resistance in series with the fan motor armature thereby speeding up the motor and increasing the air circulation. The device may comprise clockwork, or a metal bellows expanded by heating electrically and acting through a rack and pinion. Another form of device shown in Fig. 28 comprises a drum 240 which is rotated against the action of a spring 241 and held by a pivoted pawl 259 engaging a stepped cam 256 on the drum; the pawl is gradually pressed outwards by a curved bimetallic strip arranged to straighten on heating by an electric heater. The drum framing carries contact fingers 246 .. 249 adapted to contact with strips 242 .. 245 on the drum. Fig. 29 illustrates the use of the above device. The main leads 277, 278 are connected to the heating coil 263 of the bimetallic strip, the motor 276, a gas-stream heating coil 288, and to a distributing switch 267 respectively. With the switch arm on the double contacts 290, 290a, or 289, 289a the motor is energized directly through lead 294; the contacts 291, 291a provide a connection 281 to a coil 278 in series with the motor and to the contact strips 242 .. 245 on the drum. Strips 242, 245 provide for the closure of the circuit of the coil 263, and strips 243, 244, as the drum rotates, short-circuit respectively a part and the whole of the coil 278 ; on further rotation coil 263 is de-energized, the drum stopped, and the motor left running at maximum speed. The device may be employed analogously to cut in successive portions of a resistance coil in series with the heater. Fig. 23 shows a device also employable for this purpose and comprising a pivoted plate 306 adapted to be gradually swung outwards by a bimetallic strip 310 having an insulated tip and heated by a coil 311. The movement of the plate releases pivoted fingers 297 engaged in a slot therein and breaks contacts at 302. The fingers may be raised and the contacts remade by a member 313 having an operating rod 313a.
