In distillation apparatus, suitable for separating potable water from sea water, comprising an evaporation chamber surrounded by an annular condensation chamber, the vapour is moved from the evaporation chamber to the condensation chamber by a rotary compressor 54 which has flexible impeller blades 144 connected radially to a hub 146 on drive shaft 196. The vapour is drawn into the compressor through an inlet 56 in the lower shroud 138 and is discharged into the condensation chamber through a circular opening 58 between the peripheries of the upper and lower shrouds 136, 138. Each blade is formed of an elongated thin strip of material, e.g. stainless steel, folded upon itself to provide a two-ply blade with a hollow eye 218 at one end, which is inserted into a bore 208 at the periphery of the hub 146. There is preferably an adhesive layer between the plies 214, 216 of the blades. The shrouds may be made of sheet metal, plastic or fibre glass.

Abstract: 1508956 Porous vinyl/polyvinyl copolymer fibres MITSUBISHI RAYON CO Ltd 11 Aug 1976 33376/76 Heading C3C Porous fibres are made by impregnating organic fibres with 50-400%, based on the wt. of the fibre, of a liquid comprising at least one free-radical polymerizable monovinyl monomer and having a boiling point of at least 30‹ C. at atmospheric pressure and at least one copolymerizable polyvinyl monomer containing a polymerization initiator, the fibres being capable of being swollen by 30-500 vol. per cent with the liquid, polymerizing the monomers absorbed in the fibres and then dissolving out or decomposing the fibres, e.g. with a solvent or decomposing agent for the fibres. In the Examples (1-10) mixtures of (A) ethyl or methyl methacrylate, styrene, o- and p-vinylbenzyl chloride, acrylamide, acrylic acid, itaconic acid and/or methacrylic acid, (B) divinylbenzene, or methylene bisacrylamide and (C) a free radical polymerization initiator with optionally toluene tetrachloroethane, methyl acetate or aq. ammonia were used to impregnate cellulose di- or tri-acetate filament yarns or fibres, polyethylene terephthalate fibres or polycaproamide fibres which were then heated by immersion in heated baths of aq. Glauber's salt, water or saturated brine to polymerize the monomers and the substrate fibres were then removed by treatment with aq. sulphonic acid, dichloromethane, or acetone to produce porous fibres of cross-linked polymers. In Examples 9-14 the polymerized monomers were treated with ammonia, pentaethylenehexamine, sodium hydroxide, ethylene diamine, potassium hydroxide, sulphuric acid, trimethylamine and/or hydrochloric acid to form fibres having a cation or anion exchange capacity.

IPC: G09F19/00
Filed: 1927-12-12
Abstract: 313,460. Martinez, N. H., (Craig, R. M.). Dec. 12, 1927. Visible signals.-In signalling devices &c. of the type in which matter depicted in a primary colour is alternately made visible and obliterated by illuminating it with light of the same and of another colour, two or more similar representations are arranged apart so as to be at different distances from a view-point and the representations are illuminated in succession in such a manner that as one is rendered visible the previous one disappears. The nearer representations may be smaller than the further ones so that all may appear to be of the same size. Fig. 4 shows four representations 75, 86, 84, 85 of a car depicted in green and each having red headlights. The furthest representation 75 is on a board which carries also a continuously illuminated sign 80. Red lights 79 and white lights 93, 94, 95 illuminate in turn the four images 75, 83, 84, 85, and give the impression of a car rapidly approaching the observer. Fig. 5 shows a modification in which objects 119 in a casing 118 located behind a red window 113, and blue wording 117 on the window, are rendered visible only when white lights 120 in the casing and red lights 115 outside the window are illuminated. When blue lights 116 are lit, and the red and white lights 115, 120 are extinguished, the objects 119 and sign 117 become invisible and a white arrow 122 on a red ground 121 appears as blue on a dark ground. Specifications 313,457, 313,458 and 313,459, [all in Class 3(i), Advertising and displaying apparatus, Moving &c.], are referred to.

Title: Control apparatus for a two-way cable television system
IPC: H04N7/173
Filed: 1974-07-31
Abstract: 1470409 Closed circuit television systems RCA CORPORATION 31 July 1974 [13 Aug 1973] 33693/74 Heading H4R In a closed circuit television distribution system in which return signals, e.g. in respect of burglar alarms, fire alarms, polling, pay to, meter reading &c., are sent from the subscribers to the central station over the same lines as television signals are sent from the central station to the subscribers, one, or groups of, the subscribers may be isolated, so far as return signals are concerned, from the central station either when the return signal from that subscriber, or group of subscribers, is below a predetermined level, or in the absence of a particular interrogation code transmitted from the central station in respect of that subscriber or group of subscribers. As described television signals are transmitted from a central station 10, Fig. 1, in the band of 50 to 270 MHz via a trunk line 22, with repeaters 40, 41 &c., bridger amplifiers 44, feeder lines 24, 26, 28, and line repeaters 50, 51, 52 &c., to subscribers, e.g. 100, branched off from tapping points 30, 32 &c. Return signals from subscribers, in the band 5 to 30 MHz, are by-passed round the repeater amplifiers by frequency diplexers 75 and return signal amplifiers such as 60, 61, 70, 71, &c. At each return signal amplifier, e.g. 60, which is adjacent a bridging amplifier, e.g. 44, and at each return amplifier, e.g. 70, adjacent the head end, a muting circuit, 82, Fig. 2A, is provided which open circuits the return amplifier 80 output if the signal thereat is below a predetermined level. The switch may be preceded by a delay circuit 84, Fig. 2B, and/or an a.g.c. circuit 86, Fig. 2C, to enable switch operation before the signal to be switched arrives and/or to restore the signal level to a predetermined level. Alternatively the switch can be closed by an interrogation signal, in respect of the subscribers connected to that trunk, and feeder, transmitted from the central station and detected adjacent the switched return amplifier. The arrangement reduces noise on the return signals received at the head end since only noise from subscribers lines actually engaged in returning signals reaches the central station.

An overload relief valve is included in the circuit. The two ends of the ram rods are connected by chain (or belt) 10 to ensure the complementary action of the two rams. The turntable carries and runs on three rollers engaging the inclined surface of an annular runway.

Each leg 5 has a jacking assembly which comprises two jacks 10 spaced on opposite sides of the leg 5, Fig. 3 (not shown), connected by upper and lower yokes 38, 26, respectively. Each jack 10 is provided with a latchlink 20 connected to a common trunnion 22 mounted on the platform 2. Pins 33 on upper yoke 38 and pins 32 on lower yoke 26 engage notches 34 on jacking bars 36. The movement of each jack 10 to effect travel of the yokes 26, 38 relative to the associated leg 5 such that the pins 32, 33 can be moved into and out of engagement with selected pairs of laterally spaced notches 34 is shown in Figs. 4, 5. A double-acting hydraulic actuator 42 is pivoted between a plate 46 of trunnion 22 carried by the platform 2 and with it coacts a spring capsule 50 with switches 84, 88 to indicate that the pins 33 are respectively seated in or clear of the notches 34. Actuator 62 coacting with spring capsule 74 with switches 86, 90 acts similarly on pins 32. Successive stages in raising the platform 2 are shown in Fig. 5, the jacks 10 acting in compression.

The products are extracted from the acetic acid solution with ether and then chromatographed if necessary to separate isomeric forms.  Alkynyl esters are prepared from alkynyl alcohols and acid chlorides, e.g. dipent-4-ynyl sebacate, dipropargyl sebacate, dipent-4-ynyl adipate, dipropargyl adipate and but-3-ynyl under-10-ynoate.  Alkynyl ketones are prepared by warming acetylenically unsaturated acid chlorides with triethylamine, e.g. heneicosa-1,20-diyne-11-one from undec-10-ynoyl chloride.  The copper acetylides of the alkynyl esters and ketones are prepared from cuprous chloride, ammonium carbonate and the acetylene compound.  The cyclic lactone of 15-hydroxypentadecanoic acid is produced by cyclising but-3-ynyl undecynoate and hydrogenating the enyne lactone formed.  Hydrolysis of the saturated lactone yields 15-hydroxypentadecanoic acid.  Specification 922,409 is referred to.
