Title: Solid base-stock moulding material
IPC: C08L81/00
Filed: 1948-11-01
Abstract: A porous mouldable material, particularly for the manufacture of printing-plates and consisting of natural rubber, butyl rubber, butadiene-acrylonitrile copolymer, or an organic polysulphide having dispersed therein a finely-divided leachable filler is prepared by mixing the filler with sufficient evaporable solvent for the rubber to wet the particles but insufficient to dissolve the rubber completely, the solvent being inert to the filler, and milling the mixture into the rubber which has been previously milled in a cold-roller mill, the product being then sheeted and the solvent allowed to evaporate.  Filling and vulcanizing ingredients are incorporated into the rubber during the preliminary milling.  The leachable filler may be sodium nitrate ground to pass a 100-mesh screen and may constitute 42-74 per cent of the mass.  The solvent for the rubber may be toluene or tetrahydrofurfuryl alcohol and isooctane, and is subsequently removed at a temperature of 160 DEG  F.

Filed: 1946-09-23
Abstract: 616,928. Pit props. VOGEL, W. Sept. 23, 1946, No. 28421. [Class 20(ii)] An adjustable pit-prop comprises a lower tubular member a and an upper member b preferably tapered sliding in the lower member anc presenting channels for the reception of blocks e, e' and wedges f, g carried by the lower members the wedge g being attached to this member whilst the blocks e, e<1> anc wedge f are loose blocks and wedges having friction faces where they contact the upper member b anc being surroundec by a removable steel tension band n which they engage through rollers p , and further wedges h, o. The blocks e, e<1> are held against vertical movement by the lower member a, the wedge f being capable of a limited downward travel l determined by the adjustable stop k against which it is urged initially by a spring i. After the prop has been clamped by the wedge o, any collapsing movement will cause movement of the wedge f and, hence, tightening of the band n. When the the wedge l has reached the end of its travel resistance to collapse will still take place, though at a diminished rate during any further collapse of the prop, because of the taper of the upper member b. The stop k may be adjusted to prevent movement of the wedge f. This wedge may be omitted altogether or combined with the wedge o.

Title: Improvements in or relating to variable inductors
Inventor: DOELZ MELVIN L
IPC: H01F21/00
Filed: 1955-10-06
Abstract: 771,661. Inductors. COLLINS RADIO CO. Oct. 6, 1955, No. 28521/55. Class 38 (2). A variable inductor comprises a base-plate 10 from which a pair of end plates 11, 12 extend in an upward direction, a coil former 13 being rotatably mounted between the two endplates, a roller assembly 27 comprising two rollers 31, 32 being carried by one or two lead screws 16 or 17, the coil former 13 and the lead screws being geared to driving means-such as an electric motor-and a flexible conductor 38 which is wound around one end of the former 13, passed over the two rollers 31, 32 so as to pass between two contacts 42, 43 on the roller assembly 27 and then wound around the opposite end of the coil former 13. A conductive rod 47 is also mounted between the end-plates 11, 12 and the roller assembly 27 is in contact therewith by means of a contact 48 carried by the assembly 27. When the former 13 and the lead screws 16, 17 are rotated by means of the motor the roller assembly moves parallely to the former 13 whilst the flexible conductor 38 is unwound from one end of the former and wound on to the other end thereof. The terminals of the device are formed by the end 49 of the rod 48 and two members 41, 46 mounted on the end-plates 11, 12 and in sliding contact with conductive bands 39, 44 to which the ends of the flexible conductor 38 are secured. The two parts of the coil are thus widely separated, thus decreasing the mutual inductance between the two parts.

Title: High frequency semiconductor device
IPC: H03B7/06
Filed: 1975-07-07
Abstract: 1494248 Semi-conductor devices MITSUBISHI DENKI KK 7 July 1975 [5 July 1974 12 Sept 1974] 28558/75 Heading H1K In a semi-conductor device comprising upper and lower terminal members which, with one or more intervening annular dielectric members form a housing for, e.g., a Gunn effect or IMPATT semi-conductor diode chip electrically connected to both terminal members, an inductance is provided which forms a parallel resonant circuit at a frequency within the operating range with the capacitance of one or more of the dielectric members. In the device illustrated in Fig. 4 an inductance 52 consisting of a coil of gold wire or foil is connected between "Kovar" (Registered Trade Mark) rings 30, 32 silver soldered between ceramic annuli 22, 24, 26 immediately before the housing is sealed by silver soldering terminal member 42 to "Kovar" ring 42b. Alternatively it can be connected between the upper or lower terminal member and the nearest adjacent ring, or, if the uppermost dielectric annulus 26 is dispensed with, the only ring. Even this ring may be eliminated in which case the inductance is connected in series with a capacitor between the two terminal members. In a variant, instead of connecting the upper electrode of the chip to ring 42b, as shown, via two leads 50A, 50B formed from a single gold wire one of the leads may be connected to ring 24b so that the upper dielectric annulus forms a capacitor in series with the lead, to provide a series circuit resonant at the operating frequency. The same effect may be achieved by dispensing with upper annulus 26 and connecting the lead to terminal 42 via a titanium oxide based capacitor soldered to ring 42b. In either case the inductance of the other lead should be increased, e.g. by lengthening to avoid forming a parallel resonant circuit with the first lead-capacitor combination. The rings may be divided into segments or replaced by metallizations on the faces of the annuli, which are alternatively of low loss organic material, and the inductance located outside the housing to facilitate replacement. The device which has an admittance substantially the same as that of the unhoused chip, may be coupled to a cavity resonator to form a wide band HF oscillator.

Abstract: Carbon monoxide is absorbed by a basic lithium compound, the resulting lithium formate is dried and heated to 350-500 DEG  C., methyl alcohol, acetone, formaldehyde, &c. are condensed from the gases evolved, and the solid residue is re-converted into the formate.  An aqueous solution of lithium hydroxide may be treated at 160-170 DEG  C. with carbon monoxide at 20-30 atmospheres pressure. Alternatively, a suspension of lithium carbonate may be treated with carbon monoxide under 70 atmospheres at 120-250 DEG  C., the gas mixture formed being freed from carbonic acid by absorption under pressure in water and re-used.  Producer or water gas may be used instead of pure carbon monoxide.  Residual gas from the distillation of the formate may also be used, giving after treatment a gas rich in hydrogen, or even pure hydrogen. The formate obtained by evaporation is powdered and heated, preferably in thin layers in a shallow pan, revolving drum, or a tubular furnace with a conveyer screw; a bath of fused saltpetre may be used in order to ensure uniformity.  Heating may be effected under reduced pressure, or in a current of moist hydrogen.  The carbon-containing solid residue may be first boiled with lime or treated directly with water or carbon monoxide as described, the carbon being filtered off from the hydrate or formate solution.ALSO:Carbon monoxide is absorbed by a basic lithium compound, the resulting lithium formate is dried and heated to produce alcohols, ketones, and aldehydes, and the solid residue is re-converted into the formate.
