Title: Process for producing thermoplastic compositions
IPC: C08F279/02
Filed: 1961-08-21
Abstract: Thermoplastic compositions are obtained by forming a solution of 1 to 20 parts by weight of a rubbery material and from 80 to 99 parts of a monomeric vinyl or vinylidene aromatic compound and subjecting the solution to polymerizing conditions while maintaining in each point thereof substantially isothermal conditions throughout the bulk polymerization of at least the last 50% of the vinyl or vinylidene aromatic compound polymerized. Rubbery materials specified are natural rubber, polybutadiene, polyisoprene and copolymers of butadiene with styrene or acrylonitrile.  Polymerizable aromatic compounds specified are styrene, halostyrenes, nuclear alkyl styrenes, alphamethyl styrene and divinyl benzene.  Isothermal conditions, i.e. \sB10 DEG C. from the control temperature, are maintained by polymerizing the solutions in the form of thin sheets, e.g. the solution may be contained in trays or conveyed on a moving belt through an atmosphere of controlled temperature.  The thermoplastic materials thus obtained may be milled with dicumyl peroxide to improve flow properties.

Filed: 1949-11-29
Abstract: 668,895. Protective cut-out systems. GENERAL ELECTRIC CO., Ltd., and HANSON, W. H. Nov. 21, 1950. [Nov. 29, 1949] No. 30598/49. Class 38 (v). A control system for electric, e.g. mining, apparatus, comprises a circuit-breaker (not shown) which is remotely controlled over a pilot circuit 9, 10 by a switch 19, the circuit 9, 10, being energized by a transformer 2 and including a half-wave rectifier 18 adjacent the switch 19, and the coils 60c, 70c of relays having contacts 6NO, 7NC in series with circuitbreaker operating coil 5. The coils 60c, 70c are in parallel with each other, and each has a series rectifier 21, 23, and a parallel rectifier 22, 24, the arrangement being such that normally coil 60c is energized and coil 70c is de-energized, so that contacts 6NO, 7NC are closed.

Patent GB-482320-A (GB)
Title: Improved apparatus for automatically checking the weights of pieces of dough in transit
IPC: B07C5/18
Filed: 1936-11-11
Abstract: 482,320. Sorting by weighing. MASON, J. V. Nov. 11, 1936, No. 30729. [Class 143] In a weighing-scale for automatically checking the weights of articles, two electric contactors carried by the scale beam select over or under weight indicators (visible or audible) if the beam tips, and a time-controlled master switch in series with both indicators and adapted to complete either indicator circuit serves also to govern the circuit of electrically operated means for abstracting a non-standard article from the stream of articles leaving the scale. As shown in a machine for checking the weights of pieces of dough in transit from a dividing apparatus, the scale beam 6 carries two mercury contact tubes 30, 31, the contacts of which are open when the beam is horizontal, that is, when loaded with a standard piece of dough. The piece of dough is deposited on a scale pan 25 retained in the horizontal position by the attraction of an electromagnet 22, the beam being steadied in the horizontal position after the deposition of the dough by a cam 35, a groove 351 in which engages a pin 40 on the beam. The cam is driven through a friction clutch by a constantlydriven motor 34. When the beam is liberated it assumes a position dependent on the weight of the dough, one of the mercury contacts being closed if the dough is of non-standard weight. An arm 46 rotating with the cam now rocks, in succession, two fingers 44, 45 attached respectively to a master switch and to a further switch, both switches being in the form of mercury contact tubes. If either of the mercury contacts on the beam are closed, the rocking of the finger 44 completes the circuit, and the over or under weight is indicated. The circuit also includes an electromagnetic device for opening a trap in the conveyer which carries away the dough pieces, whereby the non-standard dough piece is subsequently abstracted from the stream. The rocking of the finger 45 opens the circuit of the electromagnet 22 thereby releasing the scale pan to tip the weighed dough piece on to the conveyer. Instead of a trap in the conveyer, a pivoted arm may be arranged to sweep non-standard dough pieces off the conveyer. After the removal of a dough piece an abutment 352 on the cam impinges against the pin 40 and the rotation of the cam is retarded by slipping of the clutch until a further dough piece is deposited on the scale pan.

Title: Improvements in receiving systems for the detection of signals from high frequency waves
IPC: H03G3/22
Filed: 1925-12-05
Abstract: 258,131. Standard Telephones & Cables, Ltd., (Western Electric Co., Inc.). Dec. 5, 1925. Thermionic heterodyne receivers.-The oscillations received on a frame or other aerial 2, or over a line, are applied in phase opposition to the grids of a pair of push-pull detector valves 1 arranged as in Specification 130,432; whilst locally-generated oscillations from a source 4 are applied to the grids in phase agreement. The resulting intermediate frequency and its sidebands are amplified by the valvechain 6, and the output is applied to the final push-pull detector 14 through one or other of a pair of filters 11, 12. The filter 12 is adapted to pass only one of the side bands. and when this filter is switched in by the switch 13, both filaments of the detector pair 14 are active, and a local generator 19, 20 of the intermediate frequency also has its filaments energized. so as. to supply this frequency in phase agreement to the two grids of the detector 14. When the switch 13 is moved to its other position, the filter 11 is in circuit and passes both side-bands and the intermediate carrier to the detector 14, which in this case functions as a simple detector, the upper valve of the pair 14, and the local source 19, 20. being inactive. The arrangement ensures that no beats are produced in the transformer 8 by any combination of waves or wave components picked up by the aerial 2. On account of the balance between the two halves of the coil 2 and between the two grid circuits of the valves 1, the local wave from the source 4 is not radiated by the aerial. Fading effects, insofar as they are due to a displacement of phase between the two side bands, are overcome by the use of the filter 12. When the detector 14 is functioning as a push-pull pair, there is no tendency for beats or distortion arising from interaction between components of the input to the transformer 15.
