Title: Polymerising alkylene oxides
IPC: C08G65/26
Filed: 1957-05-28
Abstract: An alkylene oxide is polymerized to a polymer with a reduced viscosity greater than 1, in the presence of an amide of a Group II metal with an atomic number between 19 and 57, or of a hexammoniate of calcium, strontium or barium.  Preferred alkylene oxides are ethylene, propylene, styrene, and 1, 2- or 2, 3-epoxybutane.  Using a suitable reaction medium in which the polymer is insoluble a granular polymer may be obtained.  Suitable diluents are liquid hydrocarbons, or liquid saturated ethers, in some cases at temperatures below 90 DEG C.  The hexammoniates of calcium, strontium or barium are normally stable but decompose on heating to the corresponding amides. Amides of Zn, Cd and Ba can be made by reacting potassium amide with the appropriate bromide. Preparations should be made with exclusion of water, air or other gases reactive with the amides. Polymerization is preferably effected in an inert atmosphere, e.g. of atmospheric N2. The catalyst may be suspended in an inert liquid, e.g. mineral oil or the diethyl ether of diethylene glycol. Polymerization temperatures may vary from -30 DEG  to 150 DEG C. Preferably, it takes place in liquid phase if desired with superatmospheric pressure. A number of examples illustrate the polymerization of ethylene oxide.  A hydrocarbon gas, e.g. butane may be added to the reaction medium as a stabilizer.  The polymers are suitable as thickeners, sizes or binders.  Specifications 869,112, 869,113, 869,114, and 869,115 are referred to.

Abstract: 761,918. Magnetic recording and reproducing apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. June 9, 1955 [June 9, 1954], No. 16955/54. Class 40 (2). In a data storage system, such as that required for controlling the operations of a machine tool, instantaneous values of a variable quantity are recorded on a moving record, and are represented by the position across the width of the record of a step change in the magnetic property of the medium. In the embodiment described the step change consists of a reversal of magnetic polarity. Thus if the full transverse lines of Fig. 1 represent one polarity, and the dotted lines the reverse polarity, the slope of the dividing lines represents the rate of change of the signal values. In order to record the signal a head is employed having a rotatable toothed magnetic disc 11 arranged edge-on to the co-operating edge 13 of a magnetic 14 over which edge a record tape passes in the direction of the arrow shown in Fig. 3. The spacing of the teeth 12 of the disc 11 is substantially equal to the width of the tape. A coil 16 surrounding yoke 14 is excited by an alternating magnetizing current of rectangular waveform and having a mark-to-space ratio proportional to the magnitude of the signal to be recorded, the rotation of the disc 11 being synchronized with the said magnetizing current. Reproduction is made by a similar head, Fig. 4, but having square teeth 121 each of which has a width equal to the spacing between them and to the width of the record track.

Abstract: 569,026. Baling-presses. HINDLE, T., and BANKS, V. P. Oct. 20, 1943, No. 17217. [Class 94 (i)] A vertical baling-press for packing loose fibrous &c. material into dense bales is constructed so that the compression of the material is performed in two consecutive stages by a. primary ram B having a long stroke which forces the material M from a filling box A into a baling chamber C in which the final compression is effected by a ram D preferably operated hydraulically. Prior to the operation of the ram B, which may be raised by cords and a winch and descend by gravity, the box A is charged with a definite amount of material by the arrangement shown in Fig. 1, in which light trucks G are charged with a definite weight of material, and are raised by a lift K and passed on rails to the door of box A through which the contents of say four trucks are passed by the aid of conveyers g. Before the ram B descends a layer of canvas E', Fig. 5, adapted.to cover the top and two sides of the bale is placed below the ram which may be provided with pins to prevent displacement of the canvas as the ram descends. The ram B descends and forces the compressed material into the chamber C, and a shutter c with an aperture c<3> through which the ram B can pass is closed after the ram B commences its upward stroke. A stillage board F, to which on the underside is attached sufficient canvas to cover the remaining two sides of the finished bale, is placed on the ram D, and the ram is operated by electrically-driven hydraulic pumps, preferably of the three-ram type and operated by a series wound motor. Prior to the application of the hydraulic pressure the canvas side pieces E<1> are pulled through the doors c<2> of the chamber C and held taut by clamps. After the compression these canvases arc held in position by wires passed around the bale through grooves in the shutter c and board F. The canvases on the board F are subsequently sown in position. The refilling of the box A occurs during the action of the ram D and the material M is prevented from reaching the shutter c by means of trap doors a which are moved to tho position shown in Fig. 6 during the final compression operation.

Abstract: 947,574. Recording-apparatus. FISCHER & PORTER CO. Sept. 9, 1959 [Sept. 11, 1958], No. 17449/63. Divided out of 947, 571. Heading G1J. [Also in Division F2] A digital data recorder comprises a rotatable disc 64 driven by a stalling electric motor 48 under the control of an escapement 34 arranged alternately to restrain and permit transmission of the drive, the escapement being operated according to the receipt of pulses corresponding to units of a variable to be recorded. The pulses are applied alternately to solenoids 8,9 to oscillate their common core 16 and consequently to rock a lever 21. The lever 21 in turn rocks escapement arms 23, 24 which alternate in releasing a stud 33 projecting from the escapement wheel 34 and in arresting it after 180 degrees rotation. Each half turn of the shaft 35 causes eccentric ball races therein, in co-operation with outer races 75,76 embraced by forked ends of push bars 60, to actuate a pawl 62 to advance the disc 64 one radial position. At regular intervals of time a synchronous drivemotor advances a record sheet and initiates recording by releasing stored energy to actuate punches. If a pulse is received in this recording interval the shaft 35 turns through 60 degrees before it is arrested by a bar 319 pressed upwards by a spring 325 into the path of detents 328, 329, since the wheel 34 has been released by the escapement arms, the pulse is in effect stored. The top dead centre of the eccentric races is offset 30 degrees from the rest position so that the 60 degree rotation causes a slight advance and retraction of the disc 64 and does not alter its position enough to affect the selection of punches. After punching cam 313 and reset lever 308 free the pawls 62 from the disc 64 which is restored to zero, thereafter the bar 319 is withdrawn, the pawls 62 become operative and the stored pulse advances the disc 64.
