Simultaneously, the resin adheres to the exposed areas of the plate and does not adhere to the unexposed plate areas.
Patent GB-2083905-A (GB)
Title: Heat storage process and system
IPC: F28D20/00
Filed: 1980-09-10
Abstract: A process of storing heat wherein a heat pump 17 to 20 operated by electrical power is arranged to heat an adsorbate (e.g. water) housed in a container 14 which also houses in liquid-tight receptacles 5 a substance with a relatively low melting point and relatively high heat of fusion e.g. a hydrated salt such as Na2SO4 10H2O. At the same time adsorbate vapour is stripped from an adsorbent 13, is compressed at 21, the compressed adsorbate supplying heat to the adsorbent at 2, is condensed and is expanded at 22 and sent to liquid adsorbate in said container 14. This is usually carried on until a major proportion of adsorbate is removed from the adsorbent 13. Heat is obtained from the supply of heat stored in the hydrated salt by the process wherein the heat pump is shut off and vaporised adsorbate is allowed to pass from said container 14 into the adsorbent 13 thereby causing a rise in temperature thereof which enables heat to be supplied to the load. <IMAGE>

Patent GB-2089557-A (GB)
Title: Spectral shift reactor
IPC: G21C7/32
Filed: 1981-12-16
Abstract: A spectral shift pressurized water reactor comprising apparatus (38) for inserting and withdrawing water displacer elements (40, 82) having differing neutron absorbing capabilities for selectively changing the water-moderator volume in the core (34) thereby changing the reactivity of the core. The displacer elements (40, 82) comprise substantially hollow cylindrical low neutron absorbing rods (40) and substantially hollow cylindrical thick walled stainless rods (82). Since the stainless steel displacer rods have greater neutron absorbing capability, they can effect greater reactivity change per rod. However, by arranging fewer stainless steel displacer rods (82) in a cluster, the reactivity worth of the stainless steel displacer rod cluster can be less than a low neutron absorbing displacer rod cluster.

Title: Method of changing work- pieces in high-speed metal-cutting processing machines, and a metal-cutting processing machine for performing the method
Inventor: SEITZ HORST
IPC: B23B3/16
Filed: 1982-07-08
Abstract: The invention relates to a method of changing workpieces in high-speed metal cutting, processing machines, particularly high-speed lathes, in which the workpiece to be machined is clamped between the centre (7) of a motor-driven headstock spindle (1) and the centre (5) of a tailstock spindle (3). The workpieces are changed during continued rotation of the headstock spindle (1) by accelerating the workpiece (9), when it is decoupled from the headstock spindle with respect to driving torque, from zero to a rotational speed corresponding at least approximately to the rotational speed of the headstock spindle by driving the tailstock spindle which is positively rotatably coupled to the workpiece. The workpiece is positively rotatably coupled to the headstock spindle after this rotational speed has been attained. For this purpose, the tailstock spindle (3) is connected to a second drive motor (6) which has lower power than the main drive and whose rotational speed can be adjusted from zero to its maximum rotational speed. <IMAGE>

Patent GB-2135428-A (GB)
Title: Fluid flow control systems
Inventor: HENEKER STEPHEN RICHARD
IPC: G01F15/00
Filed: 1983-01-25
Abstract: A water flow control system, for controlling the flow of water through a tap to dispense a desired volume of water, includes a dial 2, which is rotated to an angle indicative of a desired volume. Rotation of the dial 2 causes axial displacement of a rod 10, which displacement is transmitted against the biasing force of a spring 16 to an axially displaceable gearwheel 18. Rotation of a vane 26 located in the flow path through the tap is transmitted to the gear wheel 18. The gear wheel 18 carries a circumferentially extending cam surface 20. A cam follower 22, engaging the cam surface 20, trips a control valve 8, when sufficiently displaced by the cam surface 20. The control valve 8 when tripped initiates closure of the main valve of the tap. By varying the axial position of the gear wheel a greater or lesser rotation of the wheel is required before the control valve is tripped. In this way the volume of water dispensed by the tap is controlled. <IMAGE>
