Patent GB-895981-A (GB)
Title: Improvements relating to the moulding of articles of microcellular rubber
Inventor: WEBB CHARLES ERNEST
IPC: B29D35/12
Filed: 1957-07-30
Abstract: In a method of moulding and simultaneously vulcanizing a microcellular elastomeric mass, unidirectional controlled expansion of the mass is permitted while it is maintained under an externally applied pressure greater than atmospheric, and the whole or substantially the whole expansion of the mass takes place while the pressure is applied.  The unidirectional expansion of the mass may be permitted by slightly increasing the volume of the mould cavity.  The method may be applied in the use of a machine as described in Specification 895,982 for moulding and simultaneously vulcanizing a rubber sole and heel unit to a shoe upper.
Patent GB-1058474-A (GB)
Title: Filler material and a method of making the same
IPC: C09D7/62
Filed: 1964-06-10
Abstract: A lightweight filler material for paints, putties &c. is formed from a mass of multicellular glass-like particles.  Glass, quartz or ceramic materials are pulverized and mixed with a finely-ground foaming agent such as carbon black, comminuted coke, silicon carbide, carbonates, natural or synthetic resins, or wax, and consolidated by sintering; the resin or wax may act as a binding agent as well as providing the carbon to act as the foaming agent when decomposed at the sintering temperature.  The mass is then comminuted, either by grinding or by sudden cooling of the sintered mass, and the particles are coated with a separating-material, such as kaolin or quartz powder, to prevent sticking together during the subsequent heating in a neutral or reducing atmosphere to a temperature sufficiently high to render the glass plastic and cause the carbon and residual sulphur trioxide in the glass to react.  If a thicker outer skin is desired, the first part of the heating is carried out in an oxidizing atmosphere to remove the carbon from the surface portions.

Title: Improvements in and relating to locked razors
IPC: B26B21/40
Filed: 1923-09-28
Abstract: 221,652. Fretwell, J. W. Sept. 28, 1923. Razors, safety. A razor, particularly adapted for use by insane persons, has means whereby the blade is locked against use and against removal, the locking-means being controlled by a key separable from the razor. In the form shown a normally flat blade is clamped between a guard 7 and a curved clamping- plate 8 by a locking-member 11 disposed in the tubular handle 6 and engaging a screwed stem 9 projecting from the plate, the outward movement of the member 11 being limited by a tubular member, 12 secured in the end of the handle. When the blade is clamped as shown it can neither be used nor removed but by inserting a key 18 in the handle and slightly rotating the member 11 the plate 8 is moved outwards a little and the blade tends to assume its flat form with the edges thereof protruding beyond the edges of the plate 8 sufficiently for shaving. The. blade may be provided with a. multiplicity of closely-arranged apertures adjacent its edges so that in the event of an insane person picking at the blade in endeavouring to remove it, the blade will be broken into fragments and rendered unfit for use.

Title: Improvements in radio and like receivers
IPC: H04B1/14
Filed: 1937-09-04
Abstract: 501,760. Automatic tuning and selectivity control. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., KEALL, O. E., and RUST, N. M. Sept. 4, 1937, No. 24229. [Class 40 (v)] A radio receiver provided with automatic control both of tuning and selectivity has the two systems interlinked in such manner that operation of the selectivity control causes the tuning control to tune away from an interfering signal. The A.S.C. system shown is applied to an IF amplifier 1 having a forward reaction coupling comprising the screened half-wave line 8, resistances 10, 11 and condenser 9, while negative feed-back is obtained by virtue of coils 18, 19 in the cathode leg. To these coils is coupled a normal type of selectivity control discriminator comprising two circuits 20, 21 tuned 9 kc. above and below the mid-frequency of the I.F. band; the resultant of the two. opposed rectified voltages is applied over 29, 30 as control bias to the amplifier 1 so that selectivity increases as signal strength decreases. The A.F.C. discriminator 36, 37 is of usual type coupled to a further I.F. amplifier 33. The resultant voltage applied over 44 to the frequency correcting device depends on the joint action of the A.F.C. and A.S.C. discriminators, since the resistances 41, 42, 31, 32 are in series. Depending on whether the interference energizes circuit 20 or circuit 21, the A.F.C. control voltage is so modified thereby that the tuning is centred to 'that side of the carrier remote from the interference. The selectivity of stage 1 may be varied in dependence on the relative strength of signal and interference by shunting resistance 23 by a tuned circuit, coupled to a subsequent I.F. stage and tuned to the I.F., in series with a diode rectifier, Fig. 2 (not shown). The variation in selectivity may be effected by a meter movement in the anode circuit of valve 1 which mechanically varies the coupling of the input and output circuits of that stage, Fig. 3 (not shown). Specification 479,991 is referred to.
