Patent GB-2185094-A (GB)
Title: Liquid heating system
Inventor: MOUSLEY JOHN ERNEST
IPC: F24D17/02
Filed: 1985-11-22
Abstract: A liquid, for example water, contained in a storage cylinder 1 is selectively heated by means of a heat pump 2 utilising waste or reject heat and an electric or fuel-fired boiler 3. The heat pump 2 and boiler 3 are operable to heat the liquid to a pre-set temperature, for example 55 DEG C, at which temperature, which may be adjustable, the boiler 3 cuts-out and the liquid is further heated up to a maximum temperature, for example 63 DEG C, by the heat pump 2 only. In this way efficient use is made of the heat recovered by the heat pump 2 towards the heating requirement of the liquid and the boiler 3 acts as a back-up to the heat pump 2 to assist in meeting a large demand for heated liquid sufficient to cause the temperature of the liquid in the storage cylinder 1 to fall below the cut-out temperature of the boiler 3. The heat pump 2 may collect the heat from air in an enclosure, for example a beer cellar, cold room etc., and include both a liquid cooled and an air cooled condenser so that space cooling of the enclosure can continue when the liquid heating requirement is satisfied. <IMAGE>

Patent GB-2251519-A (GB)
Title: Microwave millimetric array receivers
Inventor: BLAKE ASHLEY KENNETH
IPC: H01Q19/06
Filed: 1986-05-06
Abstract: The receiver comprises a dielectric lens 1 which directs received and local oscillator radiation onto an array of integrated antenna/mixer circuits 4 supported by a dielectric substrate 3. Each antenna/mixer circuit 4 may comprise a crossed dipole pair 5 interconnected by mixer diodes 6. A problem is the uniform illumination of the whole array, especially if it is a comparatively large one, with the local oscillator radiation. Also because the whole array is irradiated (swamped), the necessary local oscillator power may be unduly high. Herein, there is proposed the use of a steerable reflector dish or a controllably - directional antenna array 9 which directs the local oscillator radiation via the lens onto specific circuits or specific array portions. The circuits are thus scanned with the local oscillator signal, say in synchronism with the scanning of the IF signals from the circuits. <IMAGE>

Patent GB-2196212-A (GB)
Title: Raster scan digital display system
Inventor: MOREL JEANNE ELLEN
IPC: G09G1/28
Filed: 1987-09-05
Abstract: An all points addressable raster scan graphics display system is operable in two modes. In the first mode, data is extracted from a refresh store (10, 11, 12, 13), serialised (21, 22, 23, 24), modified, and applied to a display device at a first frequency. In the second mode, data is extracted from the refresh store, serialised and partially modified at said first frequency, but it is then further modified and passed to the display device at an even sub harmonic, for example half, of the first frequency. The further modification includes concatenation of successive groups of display data bits. Accordingly, with the raster scan device operating at a constant scan velocity, the first mode provides a high picture element definition but relatively low colour definition display, and the second mode provides a display with an even submultiple, for example half, the picture element definition but considerably greater colour definition. In the first mode, groups of data bits are clocked through first (32) and second (33) and third (54) gates at the first frequency, and in the second mode the combined (35) output of the first and second gates (32 and 33) is, clocked through the third gate (54) at the even sub harmonic frequency. <IMAGE>

Title: Pressure release valve for a subsea blowout preventer
Inventor: BOND JOHN ANDREW
IPC: E21B33/06
Filed: 1988-03-21
Abstract: A valve piston (14) is mounted on a shaft (16) that is slidably disposed within an aperture (18) in the lower housing of the blowout preventer (10). The valve piston (14) and shaft (16) may be extended into the central bore of the BOP in an open position by an hydraulic operator assembly (22) to allow the wellbore gases to enter into the annular space between the shaft (16) and the aperture (18) and to vent through an open vent conduit (23) to the outside of the BOP. The hydraulic operator assembly (22) is spring biased to keep the valve piston and shaft in the closed position whenever the hydraulic operator assembly is not activated. The valve piston (14) will therefore automatically close whenever there is a loss of hydraulic control. In normal operation, the hydraulic operator assembly (22) will keep the valve piston and shaft in the open position until the wellbore gases have been vented. When the venting has been completed, the hydraulic operator assembly draws the valve piston and shaft back into closed position.

Title: Piecing a rotor spinning head
Inventor: SMITH ALAN
IPC: D01H4/50
Filed: 1989-10-10
Abstract: In piecing up a rotor a yarn loop YR5 formed and is released by movement of a member 5 to allow the reserve to feed back into the rotor. A delivery nip entry control pin 12 holds the yarn Y out of the closed delivery nip formed by a driven yarn delivery roller 1 and a cooperating cott roller 2 even after release of the yarn loop YR. The pin 12 is subsequently retracted at a precisely controlled moment so that the yarn moves into the nip and delivery commences This provides for precisely controlled resumption of yarn delivery at a known speed which is preferably reduced (a) with respect to the optimum target speed of the delivery nip for the particular rotor speed used and (b) taking into account the yarn count and the nature of the material being spun. More preferably the rotor speed is itself reduced from the normal target speed and at the end of the piecing operation the rotor speed, along with the speeds of the yarn delivery nip, the package drive roll, and the sliver feed roller are increased to production target speed. <IMAGE>
