Date Dec. 10, 1992Described are a procedure for cleansing double seat a valve, especially one operating with low or no leakage, and a valve arrangement for implementing the procedure which guarantees, among other things, that the cleansing of the relevant areas of the double seat valve is possible with a minimal, economical and environmentally friendly use of cleansing or disinfecting agents. In terms of industrial process engineering, among other things, a partial stroke of a closing member exposes a guide passage (A or C) in such a manner that the cleanser stream (R) branches off via the exposed guide passage (A or C) out of the valve housing part (1a or 1b), thereby cleansing the guide passage (A or C), and at least one of the following areas, the other guide passage (C or A), the leakage hollow space (6), and the seating surface (2a) which has been made accessible. For implementing the procedure it is suggested, among other things, that a bore (4d) be provided in axial alignment in the second rod (4b) which is connected with the guide passage (A) on the one hand and with guide passage (C) on the other. It is also proposed that the transmission path between the bore (4d) and the guide passage (A) contain a branching point (V), from which a further connection is created to an ring slot (9) formed between the first rod (3a) and the second rod (4b) which is coaxially conveyed in the first. It is suggested that the ring slot (9) provide a connection to the leakage hollow space (6). The cleanser stream (R) should be released, branching into partial streams (R1, R2) at the branching point (V) (Figure 3a), by exposure of the guide passage (A) by a partial stroke of the first closing member (3) against the opening movement (H) of the valve, or of guide passage (C) by a partial stroke of the second closing member (4).

Abstract: PCT No. PCT/EP93/02758 Sec. 371 Date Jun. 5, 1995 Sec. 102(e) Date Jun. 5, 1995 PCT Filed Oct. 8, 1993 PCT Pub. No. WO94/09573 PCT Pub. Date Apr. 28, 1994A mixed combination strategy combiner for receivers operating in high capacity digital radio links and protected with space or angle diversity is described. The combiner comprises a system which calculates the amplitude dispersion in the spectrum of frequencies of the combined signal and a device which measures the power thereof. On the basis of this information and an appropriate calculation strategy tending to minimize the BER of the equipment, a microprocessor generates signals for gain control of the stage RF of the receivers and for phase shift control for a phase shifter for the local oscillator signal sent to one of the receivers. The calculation strategy consists of minimizing a polynomial function of the power and dispersion values. Dependence of the BER on the fnotch characterizing the dispersion is eliminated, normalizing dispersion in relation to fnotch.

Title: Roller shutter braking mechanism
Inventor: YOUNG ALAN PAUL
IPC: E06B9/84
Filed: 2005-07-26
Granted: 2008-01-16
Abstract: The present invention is a braking mechanism for a roller shutter including a rotating drum (11) on which a shutter (10) is wound and a spring damper (13) that is tensioned as the shutter is unwound from the drum to resist the unwinding of the shutter screen. The present invention has a braking member (20, 21) moveable between a free position and a braking position where rotation of the drum is progressively restricted by friction. The braking member is linked to the damper mechanism so that in normal operation the braking member is urged to the free position. A counter-tension member (23, 24) exerts an opposite force on the braking member, the force being less than that exerted by the damper mechanism during normal operation. The braking member remains in the free position in normal use, but in the event of a failure of the damping mechanism the force exerted by the counter-tension member moves the braking member to the braking position to restrict rotation of the drum.

Granted: 2010-03-10
Abstract: We describe a method of displaying an image holographically using a spatial light modulator (SLM), the SLM having a plurality of pixels, the method including: displaying a diffraction pattern on the pixels of the SLM; and illuminating the pixels such that light diffracted by said diffraction pattern on the SLM pixels includes a content of said displayed image. A variation in brightness of said displayed image across the displayed image is modulated by an intensity envelope determined by the diffraction pattern of an individual said pixel, for example a sinc envelope. The method further includes moving a peak or centre of gravity of the intensity envelope away from a zero order spot and towards a centre of the displayed image by imposing a pattern of phase delay across the SLM pixels, the pattern of phase delay repeating at a spatial interval corresponding to a pixel interval of the SLM.

Title: Transaction processing
Inventor: HASLER ANTHONY GERALD
IPC: G06F11/18
Filed: 1991-05-23
Granted: 1994-09-07
Abstract: A transaction processing system (for processing transactions involving several linked processors) has a master transaction manager (TM) controlling a number of resource managers (RMs) and associated resources, possibly through subordinate TMs. To ensure that consistency is maintained throughout the system, a 2-phase protocol is used, with Prepare and Commit states, so that all resources are updated to reflect the transaction (or the system reverts to its original state). This involves keeping log records at various processors. On a failure such as a processor crash, the failed processor recovers using records obtained from other processors. A TM 13 stores log records received from various subordinate RPs each record including a recovery field REG containing information about the RP organization. For recovery, the RP sends a request for log records and a mask field, and the TM 13 selects those records which match the enabled parts of the REC field. The RP can thus determine, depending on the nature of the failure, what records are required; eg for a particular recovery supervisor or a particular resource. <IMAGE>
