Patent GB-1565211-A (GB)
Title: Vlve
IPC: F16K7/06
Filed: 1975-12-19
Abstract: In order to manage with a minimum of parts which require few machining operations, the valve was designed as follows: located in the flow passage (13) of the valve, between the inlet and outlet openings (11) of the latter, is the seat-part chamber (14). This chamber contains an actuating device consisting of a rotatable, lens-shaped, relatively stiff core (18) which is surrounded with intimate, resiliently flexible contact by a flexible sleeve (17) which forms the valve-closing member. When the valve is operated by means of a handwheel (22), the core (18) is rotated about its principal axis within the sleeve (17) and thereby alters the contours of the sleeve (17). In the open position of the valve, medium can flow around the sleeve (17) through the valve. This flow space is reduced continuously in size during the closure of the valve by the deformation of the sleeve (17) until, in the closed position of the valve, the sleeve (17) rests in a sealing manner against the edges of the inlet and outlet opening (11). The valve is suitable for use as a drain valve, a radiator valve or a water-pipe valve but can also meet the hygiene requirements of the food and beverage industry. <IMAGE>

Title: A process for the preparation of low molecular weight polymers of alpha,beta-ethylenically unsaturated aldehydes
IPC: C08G2/00
Filed: 1964-12-28
Abstract: An alpha-beta-ethylenically unsaturated aldehyde is polymerized with or without a comonomer in a mixture of water and a hetone in the presence of a Redox catalyst to give a polymer having a molecular weight of from 5000 to 7500 and an aldehyde function of more than 85%.  The polymerization is preferably conducted in an inert atmosphere.  Water-soluble derivatives of these polymers are obtained by suspending the polymer in an aqueous solution containing a substance which releases sulphur-dioxide when heated.  The water-soluble derivatives may be mixed with an aqueous dispersion of starch, and act as an insolubilizing agent for the starch.  The pH of the solution is neutral or alkaline and the solution preferably contains 1% to 50% by weight of starch and 0.01 to 10% by weight of the water-soluble derivative.  Conventional additives, e.g. fillers such as clay, pigments, resins, dyes, stabilizers and plasticizers may be added.

[Also in Division B8] At least one surface of a web of corrugated cardboard is formed with grooves extending transversely to the corrugations and the web is folded about the lines of the grooves to form a supporting element wherein the side walls of the grooves snugly abut each other. As shown in Fig. 2, a web of corrugated cardboard comprising two corrugated layers 1, each faced on both sides with plane layers, is first formed with cuts 4 extending from one web surface into the corrugated layer remote from that surface. A tool (not shown) is then inserted into each cut 4 to open the latter into a channel 4<SP>1</SP>. The channel is then deformed by a further tool into a wedge-shaped groove 4<SP>11</SP>. The web, formed with a number of grooves 4<SP>11</SP>, is then folded to form a supporting element, e.g. as shown in Fig. 8. The angle between opposite side walls 5 of each groove 4<SP>11</SP> is chosen with regard to the final shape the web is to assume, so that on folding to form this shape, the side walls 5 just touch, the apices 7 at the folds not being unduly stressed by the folding. A number of shapes like that shown in Fig. 8 may be adhered to each other and to plates 8 and 9 to form the laminate shown in Fig. 10. To form the shape shown in Fig. 8, it is necessary to form five grooves all on one side of the web. If other shapes, e.g. a row of equilateral triangles formed by bending one, continuous, grooved web, Fig. 6 (not shown), are to be produced, the grooves may be formed on both sides of the web, Fig. 5 (not shown). The web may be a single layer of corrugated cardboard, faced on both surfaces, Fig. 4 (not shown).

Filed: 1969-11-03
Abstract: 1287794 Automatic roll stabilisation NATIONAL RESEARCH DEVELOPMENT CORP 23 Oct 1970 [3 Nov 1969] 53743/69 Heading G3R In an automatic roll stabilization system for a ship, the signal controlling a stabilizing fin below the water line is formed by several operational amplifiers from a single measurement of rolling motion. As described, signals corresponding to roll angle, velocity and acceleration produced with the aid of a number of operational amplifiers having capacitive and other feedback are added together in suitable proportions determined by adjustable potentiometers. The resultant signal controls stabilizing fins through a hydraulic follow-up servosystem involving a solenoid-operated valve and a variable delivery pump. A signal dependent on ship's 'speed, derived from a log, is applied through further operational amplifiers associated with rectifiers to produce a signal inversely proportional to the square of speed which is used to modify loop gain to compensate for the variation of fin effectiveness with speed. A fixed signal suited to the ship's speed may be substituted for the signal from the log if the latter fails. Amplifier saturation and diode limiting is employed to prevent excessive control signals. A manual selector switch may be operated to introduce a further operational amplifier which washes out the roll angle signal with a long integrating time constant so that the ship is stabilized without correction of long term list. In other positions of the manual selector switch the operational amplifiers may be arranged as an oscillator to produce roll of the ship artificially or the output of the amplifiers and the response of the fins to the oscillator signals may be checked on a built-in voltmeter which may also be used during normal roll stabilization.
