Title: Load-dependent Brake Pressure Proportioning Valves
IPC: B60T8/18
Filed: 1980-10-01
Abstract: The control piston 8 of a proportioning valve is subject to the pressing force of springs 11 which is adjustable in dependence on axle load by movement of a plunger 13. An annular piston 16 surrounding the control piston is subject at one end 15 to inlet pressure, and is subject at the other end to the load dependent force of a spring 12 which also bears on the plunger 13. As inlet pressure rises, the annular piston moves downwardly until it abuts the upper support 10 of the springs 11, providing at that point a second brake point in the characteristic curve of the valve. <IMAGE>

Title: Road marking vehicles
IPC: B05B9/06
Filed: 1980-10-30
Abstract: In a road-marking or other surface-spraying vehicle wherein the flow of marking etc. fluid is proportional to vehicle speed to maintain a uniform paint thickness, a tachometer generator Fig. 2 (not shown) generates a voltage proportional to the vehicle road speed which voltage controls the opening of a hydraulic valve supplying a hydraulic motor which in turn drives the pump of a spray gun system. The hydraulic fluid is suitably pumped through the hydraulic valve to the hydraulic motor by a hydraulic pump driven by the power take-off of the vehicle. By using a flow divider valve connected between the hydraulic pump and the hydraulic motor, two separate and parallel independently controllable painting systems may be provided. An intermittent line mechanism powered by the vehicle road wheels, is connected to the spray guns and to hydraulic motor bypass valves in order to provide line patterns which are independent of vehicle speed. <IMAGE>

Patent GB-2095124-A (GB)
Title: Method and apparatus for crystallizing a substance from a solution
IPC: B01D9/00
Filed: 1981-07-14
Abstract: In the crystallization of a substance from a solution, in particular the crystallisation of fats from a mother liquor containing solvents, the solution is rapidly cooled to a temperature below the crystallisation temperature. This super-cooled and hence supersaturated solution begins to crystallize only after ca. 60 to 90 seconds, so that during this interval it may be transferred to a retention tank in which crystallisation takes place. This method may be carried out either quasi-continuously or continuously.

Title: Dot matrix character printer and control system
IPC: B41J2/51
Filed: 1979-10-10
Abstract: A dot matrix character printer is of the type having encoder means producing an encoder signal alternating between two states in response to incremental changes in print head position. Encoder signal filter means (Fig. 8 shows one) remove relatively short duration noise signals from the encoder signal to thereby provide a filtered encoder signal, by sampling the encoder signal a plurality of successive times and changing the state of the filtered encoder signal only when the encoder signal is in the same state for two successive sample times. <IMAGE>

Patent GB-2094174-A (GB)
Title: Regeneration of mixed bed ion exchange resins
IPC: B01J49/00
Filed: 1982-02-15
Abstract: in mixed bed ion exchange resin regeneration processes, transfer of resin after classification is controlled by detecting a change in a parameter of transfer water dependent on ion concentration, e.g. conductivity. The process includes increasing the ion concentration of the transfer water. The increased ion concentration ensures that large percentage uncontrolled fluctuations in the conductivity of water do not mask the change required to be detected. The ion concentration can be increased by adding, for example, decationised water to the transfer water; this does not interact with the cation material, and relatively high conductivity is measured. However, it interacts with anion material, to produce low conductivity; thus in the resin transfer step a sharp change in conductivity denotes the point at which the type of resin being transferred changes. Thus cation and anion resins can be retained in separate vessels for regeneration, e.g. in regeneration of the mixed resin bed used in a condensate polisher.

Title: Pumps
Inventor: TODD JOHN JAMES
IPC: F04B1/10
Filed: 1983-04-06
Abstract: A pump cylinder (18) is driven in reciprocation relative to a hollow piston (22) within the cylinder. The piston and cylinder each have valved inlet ports (33, 34; 43, 44) at each end. A tubular member (14) communicates with the hollow of the piston centrally between the piston ends and extends perpendicular to the piston, serving further as a stationary pivot for oscillation of the piston while the cylinder is driven in a swinging reciprocation relative to the piston. The tubular member extends through and works relative to a slot (19) formed through the cylinder wall so that reciprocation of the cylinder pumps a fluid along a flow path through the valved inlet ports and along said tubular member. The cylinder is driven at low speed by a motor through a gear box rigidly secured to a tubular frame of the pump. A number of piston and cylinder devices may be driven by a common drive means, and employ a common tubular member, in a modular arrangement. The pump is simple, reliable and quiet, and is effective to provide small quantities of air at low pressure, e.g. for aeration at isolated effluent treatment plants and at fish farms.   <IMAGE>
