IPC: C08F8/30
Abstract: 1,095,485. Polyurethane films and fibres. DYNAMIT NOBEL A.G. April 27, 1966 [April 28, 1965], No. 18553/66. Heading B5B. [Also in Division C3] Films and fibres of polyhydroxyurethanes are made by reacting at least one primary or secondary hydroxyalkylamine with a polyvinylene carbonate or a vinyl carbonate copolymer containing at least 50% of vinylene carbonate units to obtain a polyhydroxyurethane, which is then formed into the desired shape and thereafter is crosslinked to obtain the final product. Cross-linking is effected by heat or I.R. rays. Preferred hydroxyalkylamines have the formula R1.NH.R2 where R1 is H, or an aliphatic or cycloaliphatic alkyl or hydroxyalkyl group of 1-6 C atoms, and R2 is an aliphatic or cycloaliphatic hydroxyalkyl group of 1-6 C atoms; examples are ethanolamine and diethanolamine. Copolymers of vinylene carbonate with acrylonitrile, acrylamide, acrylic or methacrylic esters, olefins, butadiene, styrene or substituted styrene, vinyl ethers, vinyl or vinylidene chloride, and vinyl esters may be used.

Abstract: 1,143,838. Refrigerating. MASCHINENFABRIK NEMA, VEB. 2 June, 1966, No. 24625/66. Heading F4H. [Also in Division B1] A desiccating chamber for drying air in which the humidity is changed from a dew point above 0‹ C. to one below 0‹ C., is operated so that the surface temperature of the cooler falls below 0‹ C. only when the dew point of the air in the chamber reaches 0-2‹ C., the changeover being effected automatically in response to temperature and humidity sensors located in the chamber. The automatic changeover is preferably effected so as to maintain a temperature differential of at least 10‹ C. in the chamber between the cooling surface and the air. In Fig. 3, chamber 3 contains cooler 8 in the refrigeration circuit, which also contains compressor 9 and liquefier 11. Switch 6 controls valve 7 in response to signals from regulators 1 and 2 operated by one or other humidity and temperature sensors 4 and 5. When valve 7 is thereby opened, pressure from the high pressure side of compressor 9 causes valve 10 in the low pressure line to open, thereby increasing the cooling rate of cooler 8.

Abstract: 1,231,223. Power plant. ANSALDO MECCANICO NUCLEARE S.p.A. May 27, 1968 [May 27, 1967], No.25290/68. Heading F1Q. [Also in Division F2] Out of balance forces produced by each of a plurality of engine-driven electric generators are nullified by connecting them electrically in parallel but mechanically in such a way that the out of balance forces of the engines of the individual generators substantially cancel each other. In the case of a pair of generators each driven by diesel engines the engines are arranged to be 180 degrees out of phase when the generators are electrically in phase. In general, when there are x generators their associated driving engines are arranged 360 degrees/x out of phase, e.g. at 0 degrees, 120 degrees, 240 degrees in the case of three. The means for ensuring such mechanical out-ofphase running may comprise switches 112, 114 and 212, 214 carried by the respective generators and connected in a series circuit which is only completed when the initial relative positions of the (in this case two) generators is the required one. The relative position of the switches may be adjustable. In place of contact-making switches, photo-electric means or auxiliary generators may by employed to control the inter-connection of the (main) generators in parallel. Once the required relating position has been achieved and the generators connected in parallel in this position, the fact that they are parallel will cause them to run synchronously and so remain in the correct mechanical phase relationship.

Abstract: 1,250,965. Time-alarm signalling arrange - ments. GEHAP GESFUER HANDEL UND PATENTVERWERTUNG m.b.H. & CO. K.G. Dec.11, 1969 [Dec.14, 1968], No.60430/69. Heading G3T. In a triggering arrangement for an alarm clock, time switch clock &c. a permanent magnet cooperates with a magneto-resistive member. The magnet 5 Fig. 1 may be mounted on a movable member 3 of the timepiece and alters the resistance of a field dependent resistor 1 when coincident therewith. Alternatively the magnet and resistor 1 may be stationary and a magnetic screen 9, e.g. a ferro-magnetic plate, attached to the movable member 3 changes the resistance of R1 when it moves between the resistor and magnet. The field dependent resistor 1 may be connected in series with a resistor across a D.C. supply their junction being connected to a transistor base as illustrated, Fig. 2 (not shown). Thus when the resistance of resistor 1 changes the transistor conducts and operates a buzzer, or it may switch on an electrical appliance such as a cooker oven Fig. 6 (not shown) or a radio receiver Fig. 5 (not shown). The field dependent resistor may be arcuate in shape Fig. 4 (not shown) its arc width determining the duration of a signal triggered thereby in association with the magnet. There may be two or more such resistors mounted successively along the path of the magnet to give successive signals, or alternatively arranged to provide simultaneous signals.

Abstract: 1,266,194. Evaporators, film-type; desalination of water. UNIVERSITY OF NEWCASTLE, AUSTRALIA. 9 April, 1969 [11 April, 1968], No. 18169/69. Heading B1B. Salt water is distributed from pool 11 by resilient blade 23 so that a thin film of salt water is formed on the outside surface of a hollow, heat-conductive cylinder 12, which is rotated about it's horizontal axis, and hot vapour is introduced into the interior of the cylinder through apertures in pipe 33. Some of the water is evaporated from the film; the vapour passes through outlets 31 in the casing 10, is drawn into a compressor (not shown), and the compressed vapour is introduced through pipe 33 into cylinder 12 wherein it condenses. The condensate, i.e. desalinated water, leaves the cylinder through ports 13. Residual brine is removed from the outer surface of cylinder 12 by resilient blade 24 in discharge zone 20 which is supplied with washing water through conduit 22a. The interior wall of cylinder 12 is formed with longitudinal projections or flutes 38 (Fig. 3) so that vapour condenses on the flutes, the condensate being forced by centrifugal action into channels, from which it flows to ports 13. Blades 23 and 24 may be replaced by pads of porous material, e.g. of nylon. Two or more units of the above type may be asembled for multipleeffect operation, the cylinder of the first effect being heated by steam from a conventional steam generator, the vapour produced in the first effect being used to heat the cylinder of the second effect, and so on. In another embodiment there may be a number of concentric annular vaporization and condensation zones, each defined by concentric rotatable film carriers located within a single housing. An apparatus is referred to wherein salt water is fed into a pool on the inside of the rotating cylinder, and the vapour is condensed on the outside.

Abstract: 1,266,955. Measuring fluid pressure electrically. GENERAL MOTORS CORP. April 24, 1969 [May 6, 1968], No.20936/69. Heading G1N. A fluid pressure transducer comprises two members 12, 14 joined at the open ends thereof to form a housing 10, which is divided into two sections by a diaphragm 20, supporting a resistor 39 and movable by application of fluid pressure through a bore 58 to vary the resistance of the resistor. The resistor includes two separate resistor cards 30, 32, electrically connected by a spring clip 38 see Fig. 2, which cards are mounted between insulating members 34, 36 on an upstanding portion 28 of an insulating member 26, which member supports a coil spring 29 biasing a cup 24 to urge the diaphragm towards the member 14 so as to oppose the applied pressure. The resistance at a given pressure is the sum of the resistances between the clip 38 and the contacts 40, 48 which are electrically connected to a terminal 42, and the housing respectively. The zero value of the transducer is calibrated by applying pressure sufficient to take the slack out of the diaphragm then adjusting the nut 54 which compresses a non-resilient washer 52 and produces movement of the contacts along the resistor to the zero point 60. The maximum value is calibrated by applying a pressure in excess of that required to give a maximum indication on an associated gauge, the effective area of the diaphragm then being reduced by rolling a portion 62 of the housing against the diaphragm using a suitable tool, until the effective applied pressure equals the maximum pressure indication on the gauge. The lower member 14 has a threaded portion 56 which may be screwed into a crankcase to detect changes in oil pressure.
