Title: Carbon fibre reinforced resin plastics sheet
Inventor: PAYEN DANIEL BRYAN
IPC: B29C70/20
Filed: 1969-03-10
Abstract: 1,260,409. Laminates. DEFENCE, SECRETARY OF STATE FOR. 10 March, 1970 [10 March, 1969], No. 12449/60. Heading B5N. [Also in Divisions C1 and D1] A sheet of carbon fibre reinforced resin is prepared by laying up tows of carbon fibre in generally parallel array against at least one layer or film of resin matrix material, flattening the resin and carbon fibre together to a desired thickness by the application of a rolling pressure in the general direction of fibre alignment and simultaneously applying heat in the region of the pressure application to soften the resin. The resin film may be laid on a platten or sheet from which it easily parts, the tows of carbon fibre may be aligned on the resin film, a second resin film positioned over the aligned tows and a heated roller under spring-pressure or at a desired distance from the platten passed along the second film in the general direction of the fibres. The second resin film may be substituted by a sheet of parting agent or parting agent treated material. In a preferred embodiment, one side of each of two sheets of paper which have been treated with parting agent are sprayed or otherwise coated with a resin and hardener diluted with a solvent, the solvent is allowed to evaporate and tows of carbon fibre in generally parallel array are laid up on the resin coated side of one of the sheets. The resin treated side of the other sheet is placed on top of the fibre layer to form a laminate, which is flattened and the resin softened by rolling and heating. Elimination of the solvent may be encouraged by heating, e.g. in an oven, at a temperature below the curing temperature of the resin. The sheets of paper may then be removed from the laminate. The resin used may be an epoxy resin, a polyester resin, a polyimide, a phenolic or a Friedel Crafts type resin, a preferred resin coating being 50% by wt. epoxy resin, with acetone solvent and an additional 4% of hardener. At least one pair of rollers may be used to apply the rolling pressure. A laminated article may be produced by laying several of the sheets so produced upon one another, e.g. on a mandrel or in a mould, and curing the resin content by application of heat.

IPC: A63G1/26
Filed: 1921-05-02
Abstract: 183,602. Jackson, H. P., and Jackson, T. May 2, 1921. Roundabouts consist of a rotating platform supporting cars which are reciprocated radially and are also rotated, in alternate directions, on their own vertical axes. The cars are secured to vertical shafts L, Fig. 3, journaled in wheeled carriages or trollies E that run on radial tracks D secured to the underside of the rotating platform B. Parallel rails Q, secured to the foundation beneath the platform B, form a curved track and rotate the cars by friction according as either rail is engaged by an horizontal wheel M secured to the lower end of the shafts L and positioned between the rails. The curvature of this track also causes the carriages E to reciprocate along the tracks D so that the cars also have a radial movement. Springs 0, Fig. 3, and O<1>, Fig. 2, maintain the wheel M in contact with one or the other of the rails Q. According to the Provisional Specification, the platform B may be stationary, and the rails Q caused to revolve.

Abstract: 577,312. Regulating switches. TUSTIN, A., GRAY, A. H., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Oct. 2. 1941, No. 12766. [Class 38 (v)] A regulating switch for controlling an output in accordance, both in quality and direction, with torque or pressure, comprises two elements, of which one may be fixed and the other subjected to the torque or pressure. In the example a cage supports four sets of spring tongues, the end ones only A12, B12, C12, D12 being shown, each mounted on a metal bracket 16 on insulating blocks 17 held by throughbolts and rods 5, 8, 20. As described, each block 17 has wound on it a resistance, the outer ends being connected together. The tongues about the edges of insulating strips 3, 4 carried by the cage. Arms 22 mounted on a shaft 11, running in bearings in the cage, support contact strips a, b, c, d insulated from one another and tapered in their length. Upon relative movement of the cage and shaft the strips a, c for example will bear against the contacts in the sets represented by A12, C12 successively owing to the taper of the contact strips thus cutting out the resistances connected to the tongues successively. The strips c, d may be of smaller width than a, b to operate the C and D tongues only after all the A and B tongues have been pressed. In modifications the tongues can be arranged to put resistances in place of removing them. Specification 577,315 is referred to.

Abstract: Phosphoric acid is obtained in addition to hypophosphites and phosphites by treating an aqueous suspension of an alkaline-earth hydrate with phosphorus and burning the phosphoretted hydrogen which is evolved.  In an example, sticks of phosphorus are placed in milk of lime in an autoclave and the air replaced by nitrogen. The temperature is raised in order to start the reaction and when the pressure has risen to six atmospheres the phosphoretted hydrogen is allowed to pass out of the autoclave, through lime towers to ovens in which it is burned to phosphoric acid.ALSO:Alkaline earth phosphites are obtained in addition to hypophosphates by treating an aqueous suspension of the alkaline-earth hydrate with phosphorus at an elevated temperature. In an example, sticks of phosphorus are placed in milk of lime in an autoclave and the air replaced by nitrogen. The temperature is raised in order to start the reaction and when the pressure has risen to six atmospheres the phosphoretted hydrogen is allowed to pass out of the autoclave, through lime towers to ovens in which it is burned to phosphoric acid.  After expelling the phosphoretted hydrogen remaining in the liquor in the autoclave by means of a stream of nitrogen it is filtered.  The precipitate which consists of lime and calcium phosphite is washed, dissolved in hydrochloric acid and re-precipitated by means of caustic soda free from carbonate.  The filtrate is neutralized by passing carbon dioxide, filtered after heating, and finally evaporated in vacuo in order to obtain hypophosphite.

Abstract: 1352030 Measuring speed electrically CUSTOMFLEX Inc 5 May 1971 [7 May 1970] 13230/71 Heading G1N To provide an audible indication of a change in the speed of a boat a transducer whose value changes with speed is connected in a circuit of an arrangement providing an audible output to cause this output to "motorboat" at a frequency dependent on the transducer value. As shown in Fig.3 the transducer comprises a pivoted brass rod which depends into the water and is provided with an extension tube 10, the upper end being connected by a plastics thread 6 to a ferrite core 3 movable within a coil 5 whose leads are connected with a jack plug 15. This is connectable with a socket in a portable transistor radio receiver, and connects the coil with a capacitor 17 Fig.4 to provide a series tuned circuit connected to the emitter of a transistor constituting the oscillator/mixer stage of the receiver. The resulting output comprises audible "motorboating" clicks whose frequency is dependent on the speed. It is also dependent on the tuning capacitor of the receiver which can therefore be adjusted to produce an output of a few clicks per second at any speed. Alternatively the transducer may comprise a resistive strain gauge on a rod depending in the water Fig.5 (not shown). An electric metronome may replace the transistor radio receiver.
