Title: Self:sealing dispensing valve - with housing end convex diaphragm movable inwardly against pressure to displace valve member
Inventor: SCHIESER WARREN JAMES
IPC: F16K21/04
Filed: 1977-06-27
Abstract: A self-sealing dispensing valve, e.g. for an internally pressurised container, comprises an outer sleeve housing and an inverted cup-shaped annular inner valve member. The housing outer end is closed by a normally convex flexible diaphragm and it has a frustoconical inner sealing surface.

Title: Utilisation of waste heat for aqua cultures - using submerged, pref. plastics, pipes to warm outdoor aqua culture ponds
Inventor: PROC PETER J
IPC: A01K61/60
Filed: 1977-08-05
Abstract: Waste heat is used for aqua culture plants in coastal or inland waters. Tube lines are taken from the prodn. plant to the aqua-culture plant and the water is then passed through heat exchange elements to transfer its heat to the water in the aqua-culture vessels. The tube lines pref. consist of elastic (esp. plasticse material such as ethylene-propylene copolymers, polypropylene, low density polyethylene or polybutene. The pipes can be attached to hollow tubes in the culture pons. The pipes act as heat exchange elements and can have a number of crossmembers and longitudinal sections. Alternatively, if the warm water is uncontaminated it can be fed directly back to the culture pond. To provide useful cultures to compensate for falling catches from the sea. Allows these cultures to be operated at controlled optimum conditions using waste process heat.

Title: Dual pulse train development using division - employs series of data storage units for quotient with recycle connections to selectors and division stage registers
Inventor: KESSLER HEINRICH DIPL PHYS
IPC: G06F7/68
Filed: 1978-10-10
Abstract: The division circuit operates on a number (M) by passing it through a frequency divider (FT) and a chain of storage units Z(m-1), Z(m-2).....Z(m-k)...Z(1), Z(0). Each storage unit is inter-connected with one of (k-1) selectors, S(1), S(2)...S(k-1), which also connect with register calls R(1), R(2)...R(k-1). The number M is equated with the product D.Q, where D is a given number and the quotient Q is to be calculated. D is expressed as a sum of terms of the form do+d, 10+.....d(k-1)10R-1. In operation the selectors and registers recycle numbers at various stages in the division circuit until the quotient appears in the tail end storage units Z(m-k) to Z(0). The selector stages are each made to the same design and comprise several NOR gates using MOSFET technology. The other components use NOR gates, AND gates and flip-flops.

Title: Suspension attachment system for nuclear fuel transport flask - incorporating redundancy irrespective of flask attitude when lift starts
Inventor: WEBER ROBERT
IPC: G21F5/14
Filed: 1979-01-19
Abstract: A container for transporting radio-active material, of the elongated shape used for nuclear reactor fuel elements. has its exterior fitted with 2 suspension lugs positioned at opposite ends of an axis which passes perpendicularly through its main (longitudinal) axis. Further suspension lugs are positioned on the same axis, but beyond each of its ends, mounted on support brackets, built out from the container surface. The portions of bracket on the surface may be formed as a ring which surrounds it completely. Tension links may be used as the means for the ring to grip the container periphery. Composed with an existing system in which transport flasks of the form concerned are slung from a system of a 4 coplanar lugs mounted at 90-degree intervals around the container axis, the construction described additionally provides redundancy when lifting the container into a vertical position, since the container may be turned into an orientation where the load at the 4 attachment points is uniformly apportioned.

Title: Patterned pile fabrics - uses piles of different lengths for the design
IPC: D06C23/02
Filed: 1979-04-20
Abstract: To give a patterned effect to pile fabrics, the length of the pile in the pattern is of a different length from the pile in the remainder of the material. Process gives a simple method of applying a pattern to one side of a pile fabric. Pile length in the patterned zone can be shorter or longer than the pile over the unpatterned zones, and the shorter pile length is achieved by shearing or singeing, or cutting at the patterned areas or round the patterned zones.
