Patent GB-2115490-A (GB)
Title: Rotary positive-displacement fluid-machines
Inventor: SZIRMAY ZOLTAN
IPC: F01C9/00
Filed: 1982-02-25
Abstract: A machine of the nutating-disc type that may be adapted for use as an engine or a pump comprises a piston 16 mounted obliquely on a rotary shaft 34 so that relative to the shaft it can revolve about its own axis t2 while the shaft turns about its axis t1. Slotted elements 21 in the piston are disposed radially thereof and engage slidingly with radial blades 28 fixed in a housing structure 2, which has conic inner surfaces 9 and is either fixed or rotates with the shaft. Ports (29), Fig. 2 (not shown), for the working fluid may be formed in the conic surfaces. Power-transmitting gear-teeth 30 may be attached to the housing structure. When the housing structure is fixed the piston revolves about its axis as it rotates with the shaft and nutates in the housing structure but is fixed relative to the housing structure when the latter rotates with the shaft. Modifications are described with reference to Figs. 4 to 7 (not shown), one modification being such that there are two co- operating pistons in a common housing structure (Fig. 7). <IMAGE>
Patent GB-2102591-A (GB)
Title: Timer
Inventor: GROSS THOMAS B
IPC: G05B19/04
Filed: 1979-07-26
Abstract: The time controls a dispensing machine and in particular controls the dispensing cycle for a substance such as instant potatoes comprising a primary product (solid or powder) and a liquid (water) by temporarily regulating the water portion of the cycle in conjunction with the solid or powder (potato granules or pearls) portion of the cycle. The water flow is usually controlled using a solenoid or the like while the quantity of potato is regulated by an auger and associated drive motor. The dispensing cycle is initiated by a pre-rinse period wherein only water flows. During the main part of the cycle both water and product flow into a mixing area. The cycle ends with a post rinse period that is either positive or negative; positive when the product flow stops first and negative when the water flow stops first.

Abstract: A method or apparatus for generating gas bubbles of relatively small and uniform size in a liquid medium utilises at least one rotatable member free of fins, blades or other mixing projections, e.g., in the shape of a disc or ring 16, which is rotated in a liquid medium at an edge velocity of at least 80 feet per second. A source of gas or some other fluid phase is provided proximate to the rotatable circular members to form the bubbles.
Patent GB-2105129-A (GB)
Title: Combined power line monitor and control regulator for a switching power supply
Inventor: BREYA EDWARD FRANCIS
IPC: H02M3/155
Filed: 1982-05-05
Abstract: A combined power line monitor and control regulator comprising a single transistor 62 and an integrated- circuit voltage regulator 50 and associated passive elements provides a valid and safe set of signal states for other operating circuits, including the control circuit of a pulse-width-modulated switching power supply (not shown), for any power-line voltage over a given range, regardless of rate of rise, drop- out duration, on-off cycle repetition rate, or previous signal state. A drop in ac supply causes C82 voltage to fall and T62 to turn off. QCL then turns on to disable output stages QO of the regulator. Regulation is achieved via feedback through R90, R86. <IMAGE>

Patent GB-2129527-A (GB)
Title: Valve baseplate
Inventor: STOLL KURT
IPC: F15B13/00
Filed: 1983-08-30
Abstract: A generally rectangular base plate, having long and short sides, for a multi-way valve is designed so that it may be joined together at its sides with like base plates for supporting a battery of valves. The base plate has a number of connection ducts running through it from the connection face (1) (the face to which the valve is to be fixed). Some of these ducts (4, 6, 8), that are for supplying and letting off fluid from the valve, are joined up with through ducts (13, 12, 14) running right through the base plate from one long side to the other long side thereof, whereas the ducts (5, 7) for connection with a load have their openings at another side of the base plate. The base plate is made in two parts (25, 26) with a parting plane parallel to the connection face (1) defining a top connection plate part (25) with the connection face (1) thereon and a lower connection plate part (26), such parts having mounting faces (27, 28) where they are joined together. The connection ducts (4, 6, 8) for the supply and letting off of the fluid and the through ducts (13, 12, 14) used therewith are placed in the top connection plate (25). A top section (5a, 7a) of each load duct (5,7) extends through the top connection plate (25) from the connection to the mounting face thereof, whereas lower sections (5b, 7b) of each load duct (5, 7) is placed so as to be generally parallel to the long sides of the base plate, said lower sections (5b, 7b) of the duct opening at one of the short sides of the base plate. <IMAGE>

Title: Toy vehicle
Inventor: CHENG CHOR-KIT
IPC: A63H29/20
Filed: 1984-02-20
Abstract: A toy vehicle incorporates an electric motor (14) which accelerates a flywheel in a drive housing (13) when downward pressure is applied to the vehicle so that a rear axle (18) of the vehicle rises in slots (20) and closes switch contacts (27). When the vehicle is released the axle (18) is moved downwards by a spring (21) relatively to the vehicle chassis (5), thereby opening the contacts (27) and de-energising the motor (14). Simultaneously a gear (26) on the axle (18) comes into mesh with a gear (23) rotated by the flywheel so that the vehicle is then driven while the energy in the flywheel is dissipated. <IMAGE>

Title: Gas coolant system
Inventor: STOW ROGER VALENTINE
IPC: F25C1/12
Filed: 1984-04-25
Abstract: The system comprises a water reservoir (1), means (3) for chilling water in the reservoir, and means (5) for withdrawing chilled water from the reservoir, and for bringing withdrawn chilled water into intimate contact with the gas to be cooled; wherein said means (3) for chilling water comprises means (29, 31, 33) for forming ice and introducing the ice formed into the reservoir to chill the water and to create a store of cooling capacity so that subsequently chilled water can be withdrawn to cool the gas and then be returned to the reservoir again to be chilled. The ice is formed on refrigerated plates 33 which are sprayed with water from nozzles (37). When a predetermined thickness of ice has formed the refrigeration cycle is reversed to the ice to separate from the plates and fall into the reservoir (1). <IMAGE>

Title: Microwave device
Inventor: PARKINSON GRAHAM GEORGE
IPC: H01P1/218
Filed: 1984-07-14
Abstract: A microwave device including a ferrimagnetic resonator, e.g. a YIG-tuned oscillator, includes a resonator heating means. The resonator, e.g. a YIG crystal, 17 is supported in a magnetic field in a resonant cavity by a dielectric rod 20 cantilevered from a support 19 in which it may be axially rotatable to align the crystal with the field. The heating means may take the form of a semiconductor integrated circuit 25 of the type including a controlled heater for temperature stabilisation, and is supported in contact with the cantilevered portion of the rod, by thermally conductive adhesive or by an intermediate metal body giving a greater thermal contact area with the rod. Apart from smaller dimensions, because the heat is transferred more efficiently to the crystal rather than the support 19 (unlike conventional heaters which are in support 19), the low current i.c. heater is adequate, and the heater current is obtainable from internal oscillator circuitry without the need for a separate supply. <IMAGE>
