Abstract: A microporous biocompatible material is formed by pre­paring a segmented polyether urethane urea solution containing 25% ± 1.5% solids dissolved in a solvent. The solution has sufficient viscosity to be preshaped and formed into the desired thickness of the finished article, then immediately immersed into a precipitation bath in which the solvent in the solution is miscible for a time interval sufficient to cause the solution to set up into an opaque elastomeric article. The article is immediately removed from the bath, any excess solvent extracted and then dried at a temperature on the order of 35°C. to 70°C. followed by heat treating by annealing for approximately sixty minutes at a temperature at 100°C. to 130°C. The void volume of the membrane solution is controlled to within the 50% to 80% range and the pore size from ca <0.1 to several mms. as well as the shape of the pores and solid structures between them, thereby enabling close control over the characteristics and structure of the material as well as other variations in structural characteristics and porosity across the thickness of the material according to its intended application and use.

Abstract: PCT No. PCT/GB86/00043 Sec. 371 Date Nov. 20, 1988 Sec. 102(e) Date Nov. 20, 1988 PCT Filed Jan. 23, 1986 PCT Pub. No. WO86/04268 PCT Pub. Date Jul. 31, 1986.Apparatus for collecting and discharging waste material comprises peripheral rows of teeth arranged on rotatable cylindrical shafts. The teeth on each shaft intercalate so that an entrapment zone for waste material is formed thereat during contra-wise rotation of the shafts. The teeth in each row pass through respective slits formed between the blade edges of rectilinear scaper blades placed between the rows and resting on the shaft. The scraper blades remove waste material from and between the teeth for discharge from the machine. To prevent the waste material being caught by cutting action between the leading faces of the teeth passing the scraper blades edges the magnitude of the angle formed at any time between those leading faces and the blades edges as the teeth pass through slits, has a value determined by the shape of the leading faces of the teeth and blade edges of the scraper blades so that the inducement of frictional engagement in relation to the materials being handled is never sufficient for a biting or cutting action to ensue.

Abstract: Braided line is manufactured by drawing off filaments (3) from a carousel of bobbins (1) which are caused to follow interweaving paths about a common axis. The line can be tapered by cutting selected filaments at intervals and continuing the braiding with a progressively reduced number. Each cut off filament (14) leading from the braid point (8) is kept co-axially aligned by the air flow into a suction tube (6) within the carousel while the remaining filaments (3) are braided around it. The selection and cutting of the filaments can be automated, under computer control.

Abstract: One or more heat exchangers and catalyst beds are disposed with rotational symmetry about a central gas feed tube in an ammonia converter with inlet and outlet for process gas.  Temp. is controlled by passage of a control gas to the central tube, which at its lower end has adjustable outlets (18), whereby the control gas, together with quenching gas or possibly process gas with different parameters, can be mixed with the process gas before the latter enters the catalyst beds, and/or control gas is mixed with process gas after the latter has passed through catalyst and heat exchanger. The central tube has adjustable distribution apertures synchronised with each other.  A first central tube may be coaxial with a second tube leading to a further heat exchanger and supplying gas to a different catalyst bed.

Abstract: The regulator has at least one inlet connector (10) for receiving a brake-operating pressure, and at least one output connector (13) for supplying braking pressure to the brake members of the vehicle. It includes valve means for controlling the braking pressure, situated in the body and including a rocker arm (20) with a variable fulcrum (33) which is arranged to determine the ratio between the brake-operating pressure and the braking pressure in dependence on the position of the fulcrum (33). The movement of the rocker-arm fulcrum (33) on variation of the load is controlled by a control device (60; 21-42) comprising a body (60) in which at least one piston (24) is sealingly slidable, the piston being movable, against the action of first and second reaction springs (29, 30), by an operating pressure which depends on the load bearing on the vehicle. The first spring (29) is inside the second (30) which is locked against rotation but translatable in the body (60). The piston (24) carries a member (33) which can cooperate with the rocker arm (20) to act as its fulcrum (33). A manually-operable adjustment device (35-42) is associated with the body (60) of the device for moving the fulcrum (33) and is adapted to enable the loading of the first spring (29), its position relative to the body (60) and also the elastic constant of the second spring (30) to be adjusted independently.
