Abstract: A moulding composition comprising (1) at least one thermoplastic alkenyl aromatic resin which comprises polymerized monovinyl aromatic hydrocarbons containing a single benzene nucleus and/or copolymers of at least one such monovinyl aromatic hydrocarbon and from 30 to 1% of an alpha-alkyl styrene and (2) at least one synthetic rubber prepared by the emulsion polymerization of styrene with from 30 to 70% of butadiene is made by mixing with the rubber latex 0.5 to 5% of a polyethylene glycol of average molecular weight from 200 to 600, drying the latex and incorporating by mechanically working the latex solids with the alkenyl aromatic resin, while heat plastified at 150 DEG  to 250 DEG  C., in a proportion of from 15 to 40% of the latex solids to obtain a uniform composition.  The alkenyl aromatic resin may be a polymer of styrene, vinyltoluene, ar-ethylvinylbenzene, vinyl xylene, ar-isopropylvinylbenzene or copolymers of one or more of these with alpha-methyl-, or -ethylstyrene or para-methyl-alpha-methylstyrene.  The latex solids may be comminuted prior to mixing with the aromatic resin.  In an example a mineral oil is included in the composition as a lubricant.  The use of polyethylene glycols of molecular weight outside the above range is mentioned.  Specifications 672,290 and 672,667, [Group II], are referred to.

In the variably tunable band pass filter for a radio receiver shown, each inductance comprises two U-shaped cores F1, F2 of comminuted magnetic materal arranged with their limbs facing one another so as to provide a rectangular magnetic circuit including two series airgaps embraced by astatically-arranged coils A1, A2, connected in series. A right and left-handed screwed shaft SH operated by a knob CH is journalled in a fixed bearing member BM and is threaded through right and left-handed nuts N1, N2 fixed to frame plates P1, P2 carrying the cores F1. F2, so that these are caused to approach or recede from one another according to the direction of rotation of the shaft SH. Surrounding the coils A1, A2, is a screening cylinder SC1 which co-operates with electrodes OE1, OE2 to form a condenser. The electrodes OE1, OE2 are carried by the plates P1, P2 and are so shaped that proportional variations of inductance and capacity occur when the inductances are varied. In a modification, only one movable magnetic core F1 is employed in each variable inductance and only one movable electrode OE1 in each variable condenser, the movable cores F2 being replaced by fixed straight bars of similar material.

Title: Improvements in or relating to electrically operable number indicators
IPC: G08B5/24
Filed: 1940-06-25
Abstract: 542,146. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd., and MYATT, E. R. June 25, 1940, No. 10859. [Class 40 (i)] In an indicator comprising a number of digit wheels set in succession by trains of impulses, the change over from one digit wheel to the next is dependent on off-normal movement of the first wheel. As shown in Figs. 1, 2, each digit wheel DW is driven by an individual two-winding motor DWM of the kind described in Specification 538,723 which operates step-bystep in response to the application of alternate battery and earth at impulse contacts IC. A relay M which is momentarily disconnected at contacts DC after each impulse train controls latches L for the movable contacts 2 of the change-over contact sets SS associated with the digit wheels. Thus, when a digit wheel DW moves off-normal, the contact 2 is no longer held by the projection P but it cannot change over until the latch L is withdrawn at the end of the impulse train. The contact sets SS are arranged in a chain circuit, which may be extended when all are operative to a device CH arranged to give a fault signal should any further impulses arrive. In Fig. 3, the digit wheels are provided with individual relays EM which are simultaneously operative, and each movable contact 2 is controlled by the armature AR of the corresponding relay EM. The withdrawal of the projection P when the digit wheel DW moves off-normal allows movement of a latch LR to prevent the armature AR from coming up again when it is released at the end of the impulse train.
