Patent GB-2086563-A (GB)
Title: Energy transfer apparatus
IPC: F24S10/95
Filed: 1981-10-19
Abstract: Energy transfer apparatus, intended primarily as a solar energy collection system, has a collector panel with relatively thin sheet metal outer walls (3,4) and a relatively rigid, corrugated inner wall (2). The walls (2, 3, 4) define an evaporation space (8) and a condensate return passage (9), both of which are in communication with a vapour collection vessel (12) at the top of the panel. A single pipe (5) connecting the vapour collection vessel (12) with a coiled tube (6) in a preheat vessel (7) provides a path for upward transmission of vapour and downward return of condensate. The system operates by transfer of latent heat energy of vapourisation, the preferred heat transfer fluid being de-ionised water. Normally the system operates with a negative internal pressure so that the outer walls (3) and (4) are drawn into engagement with the corrugations of the wall (2). <IMAGE>
Patent GB-2091000-A (GB)
Title: Automatic control of engine operation
IPC: F02P17/00
Filed: 1981-11-12
Abstract: The timing of delivery of fuel to a compression ignition engine is determined and adjusted by observing the peak pressure attained in a combustion chamber during a fueled working stroke of the engine. This is compared with a desired peak pressure and a timing adjustment made. The condition of the engine is taken into account by comparing an actual pressure ratio with a desired pressure ratio, the actual pressure ratio being determined by obtaining a peak pressure signal when fuel is supplied and a peak pressure signal when no fuel is supplied or a pressure signal at a fixed point in the working stroke before fuel is supplied. The desired pressure ratio is provided by a circuit to which signals representing engine speed and fuel quantity are supplied. It is also stated, that the ignition timing in a spark ignition engine may be similarly controlled. <IMAGE>

Title: Piezoelectric oscillatory gyroscopes
Inventor: BURDESS JAMES STONEHOUSE
IPC: G01C19/5642
Filed: 1982-12-03
Abstract: A gyroscopic device comprising a beam, column or other continuous unitary structure of consistent vibratory characteristics along its full length is made of piezoelectric material. The piezoelectric effect is used both to excite the structure into resonant vibrations along a first axis and then, when a rate of turn is applied along a second axis at right angles to the first, to detect that rate of turn by sensing vibrations set up in the beam in a direction parallel to a third, orthogonal axis due to Coriolis forces resulting from the applied rate of turn. The beam may be held at both ends, or may be supported at one end only with the other end free. The vibrations applied to and sensed within the beam by means of the piezoelectric effect may be parallel, transverse and radial relative to the beam axis, or may be in a rotary sense around that axis. A mode of vibration in which opposite faces of the beam oscillate in parallel directions but out- of-phase is also disclosed. <IMAGE>

Title: Integrated cyclic scrubbing and condensate stripping process for the removal of gaseous impurities from gaseous mixtures
Inventor: OSMAN ROBERT MICHAEL
IPC: C01B3/52
Filed: 1982-12-21
Abstract: A process for removing acid gases such as CO2 and H2S from gas streams using a cyclic aqueous alkaline scrubbing solution which is circulated between an absorption stage (1) and regeneration stage (2) is improved by integrating within this cyclic system a process scheme wherein, by virtue of an initial cooling step 6), condensed steam having gaseous impurities dissolved therein is recovered (8) from the feed gas and let down (9) to a pressure below which scrubbing solution regeneration takes place. While maintaining this pressure, the process condensate is heated, boiled and stripped (11) to evolve a vaporous mixture (13) comprising steam and gaseous impurities which are compressed (14) and introduced into the regeneration stage (2). By this process, useful work is performed by low temperature process streams thereby improving the overall efficiency of the cyclic process. <IMAGE>
