Title: Woven electro-magnetic shielding bag that is thermally conductive but electrically isolating for its contents
Inventor: CHEASLEY ALAN
IPC: H05K9/00
Filed: 2009-07-22
Abstract: This device comprises a bag (A) that can provide an electromagnetic shield around electronic devices or PCBs (B) and thus reduce their potential to interfere with other equipment, and to disrupt telecommunications. The bag is made of shielding material in two layers - an inner flexible electrically insulating layer, and an outer wire woven layer which can be connected to an earth or ground.A refinement uses Graphene Oxide for the inner layer, and possibly as and additional third outer layer; the graphene oxide is both an electrically insulating and also an excellent thermal conductor, thus allowing the shield to also act as a heat sink. To refine this further, using a bonded three layer Graphene oxide, wire weave, Graphene oxide bag, a Peltier effect solid state cooling device can be attached to pump heat away from contents of the bag.

Abstract: 166,330. Richardson, S. April 9, 1920. Lenses, grinding; bevelling.-A machine for bevelling the edges of lenses comprises a bevel-edged grinding-disc 1 on a shaft 7, and a swivel head 21 pulled towards the disc by a spring 25. The head 21 is mounted between collars on a spindle 17, which is reciprocated by means of a cam 18* engaging a stationary pin 18‹. A indicator 22 is provided so that the cam can be brought to the correct position when centring a lens. A lens 5, carried by a spindle 9, is held between pads 10; a screw 11, with spring adjustment, clamps the lens. The spindle 9, which is rotatably mounted in the head 21 and carries a templet 26, is driven from the spindle 17 by gears 19, 20. The spindle 17 is driven from the shaft 7 by means of belts, an epicyclic reduction gear 14, and a clutch 18. The spindles 9, 17 can be adjusted towards or from the disc by means of a plate 23 and screws 24. A guideplate 27, contacting with the templet 26 and adjusted by a micrometer screw 29, may have a protuberance 28 so as to prevent the lens from grinding on the line of junction of the beveledges of the disc. A number of discs may be mounted on the same shaft so as to operate simultaneously upon a number of lenses. In a modification, the disc has an axial reciprocation instead of the lens-carrying spindle.

[Class 40 (v)] In a superheterodyne receiver of the "midget" type having poor selectivity between the aerial and first detector, means are provided for simultaneously increasing the gain of the I.F. amplifier and reducing the gain of or the input to the R.F. amplifier. This may be done by ganging the respective bias controlling resistances to move in opposite directions, by providing a common biassing resistance 11 with a single slider 10 as shown in Fig. 4 or by providing a resistance, the slider of which simultaneously adjusts the bias of the I.F. amplifier and the input to the R.F. amplifier. The purpose of the invention is to enable interference due to two stations differing in frequency by about the intermediate frequency to be reduced. The Specification as open to inspection under Sect. 91 comprises also the arrangement shown in Fig. 5, (Cancelled), in which the input to the R.F. amplifier and the bias on the I.F. amplifier are adjusted by operating a single slider 101.

Title: Foamed natural and/or synthetic rubber latex coagulable at reduced temperatures
IPC: C08L21/00
Filed: 1955-04-07
Abstract: Foamed latex sponge is prepared by compounding natural and/or synthetic rubber latex with a dispersion of an inorganic substance capable of becoming agglomerated at reduced temperature, foaming the latex and cooling it to form a copious precipitate of the said substance thereby to coagulate the latex, and then vulcanizing the product.  The inorganic substance is preferably silica obtained by treating sodium silicate with a cation-exchange resin. The precipitation may be improved by adding to the latex an organic polyamine, e.g. triethylene tetramine or ethylene diamine, an amino acid such as glycine, or a protein such as glue or casein which hydrolyses to form amino acids.  The latex may be that of butadiene-styrene copolymer, or a mixture of natural rubber latex and butadiene-styrene copolymer or polybutadiene latex in the proportions of 90:10 to 10:90 by weight.  In an example 2 to 5 parts of vulcanizing agent, 1 to 10 parts accelerator, and 5 to 50 parts of an 18 per cent aqueous dispersion of colloidal silica, and 5 to 15 parts zinc oxide, are added at about 70 DEG  F. to 100 parts latex.  The mix is then frothed with the addition of 1 to 5 parts froth stabilizing agent, and coagulated by reducing its temperature below 32 DEG  F.  The coagulated froth is then vulcanized by heating.ALSO:Foamed latex sponge is prepared by compounding natural and/or synthetic rubber latex with a dispersion of an inorganic substance capable of becoming agglomerated at reduced temperature, foaming the latex and cooling it to form a copious precipitate of the said substance thereby to coagulate the latex, and then vulcanizing the product.

Title: Improvements in or relating to transistor circuits
Inventor: ABBOTT LEONARD CHARLES
IPC: H03K3/282
Filed: 1958-03-31
Abstract: 884,301. Visible signalling apparatus. DIETZ CO., R. E. March 31, 1958, No. 10255/58. Class 118. [Also in Group XL (c)] A transistor oscillator for operating a flashing- light beacon comprises two normally non-conductive transistors one of which is connected in series with a load resistor (the flashing lamp) across a suitably poled D.C. supply and the other of which is associated with a condenser charging circuit whereby it is periodically rendered conductive, the current through said other transistor being applied to said one transistor to cause it also to conduct so that a large current flows periodically through said load resistor. The circuit comprises two transistors 15, 20 of opposite conductivity types, the transistor 20 being connected as shown between the base electrode of transistor 15 and the junction point of the resistor 12 and capacitor 14 connected in series with signal lamp 11 across the battery 10. A bias potential is applied to the base of transistor 20 by means of resistors 27, 28 to hold the transistor normally non-conductive. When, however, due to the charging of capacitor 14 the emitter potential of transistor 20 becomes more negative than that of the base electrode the transistor conducts, thus applying a current to the transistor 15 which also conducts. As a consequence the point 32 becomes more positive so that the base of resistor 20 also becomes more positive and conduction in transistor 20 increases cumulatively. The conduction in transistor 15 increases similarly and the lamp 11 is lighted. This continues until capacitor 14 has discharged through transistor 20 to such an extent that the transistors are no longer held fully conductive whereupon a reverse cumulative process occurs and both transistors are switched off. The cycle then repeats itself with the charging of capacitor 14. In a modification, Fig. 2 (not shown), a resistor, which may be arranged in series with a suitably poled D.C. source, is connected between the base of transistor 15 and earth. By this means leakage currents flowing in the transistor 20 are bypassed to earth.

Abstract: 315,017. Evans, W., E., (Allgemeine Elektricitõts-Ges.). April 5, 1928. Axle-trucks and bogies.-A truck or bogie frame for locomotives and railway vehicles is connected to the ends of a driving axle so as to move it laterally on curves by means of a yoke or a system of rods,' the yoke or rods passing through or beyond the bogie frame and outside the driving wheels. In the construction shown, the truck frame c<1> is connected to the main frame by a fixed or sliding pivot d' and the running axle a<1> is pivoted at one end of the truck frame. A yoke f<1> is' also pivoted at e<1> to the truck frame and its arms extend beyond the driving wheels g<1> to the ends of the driving axle b<1> to which they are connected by ball or other joints u. Thus, when the axle a<1> moves laterally on a curve the frame c' is rocked about the pivot d<1> and the axle b<1> is also moved laterally, this axle sliding in its axle-boxes. Instead of the yoke a transverse bar may be used pivoted at d<1> and connected at its ends to longitudinal levers pivoted to the main frame and to the axle ends. In a modification the yoke is connected to the axle-boxes which are thus caused to slide laterally and carry the axle with them.
