Title: Controlling the superheat temperature of a refrigeration system
Inventor: BENDTSEN CHRISTIAN
IPC: F25B41/06
Filed: 1993-12-10
Abstract: A refrigeration system comprises a compressor (1) and a condenser (2), between which there is arranged at least one evaporator (4) which at its input side has a controllable injection valve (5). A control device (7) which is connected to temperature and/or pressure sensors (8, 9, 11) on the input side and output side of the evaporator and actuates the injection valve (5). The desired value of the superheat temperature of the evaporator (4) is modified in dependence upon the degree of opening of the injection valve (5). Because of fluctuations in load the evaporator may become completely filled with liquid refrigerant. In order to activate the evaporator (4) quickly the control device (7) alters the correlation between the superheat temperature and the degree of opening of the injection valve (5) when the injection valve (5) falls below a predetermined degree of opening. Either the valve (5) can be prevented from closing completely or, after closing, a more rapid re-opening effected. <IMAGE>

Title: Absorbent article containing delayed activation superabsorbent
Inventor: STEGER CHRISTINA
IPC: A61F13/53
Filed: 1994-06-14
Abstract: An absorbent article, such as a diaper, incontinence guard, sanitary napkin and the like, has a structure which includes hydrophilic fibres and particles of a superabsorbent material having a delayed actuation time. The crotch part of the article has a wetting region (16) within which the major part of the discharged fluid is directed. The absorbent structure in that wetting region includes superabsorbent particles that are encased in a material that will only dissolve slowly in and/or be penetrated slowly by the fluid to be absorbed so that the superabsorbent material will not begin to absorb fluid and swell to any appreciable extent until the encapsulating material has dissolved and/or been penetrated by the fluid. Conventional superabsorbent material (15) is also in those parts of the structure that are located outside the wetting region. A mixture of two or more superabsorbents having delayed activated times may be employed. This structure overcomes the problems associated with gel blockage. <IMAGE>

Title: System for eye detection and gaze direction determination
Inventor: ROBINSON MICHAEL GERAINT
IPC: G06F3/038
Filed: 1996-08-01
Abstract: An eye detection system comprises a source, such as an infrared laser diode (2), for emitting a divergent beam of radiation (5) and a spatial light modulator (4), which is controlled so as to act as a deflector for scanning the beam through a region which may be occupied by an observer's eye. A detector (7) detects radiation which is retro-reflected by the eye (12) back along the path of the scanning beam (6). The deflection angle of the spatial light modulator (4) and, for a position sensitive detector (7), the location of the centre of illumination on the detector can be used to determine the angle to the centre of the pupil of the eye (12). This system can be incorporated into a VDU with two further light sources (9 and 10) which are used for detecting the angle of the glint reflection, so that subsequent to the detection of the eye, its gaze position on the screen (1) can be determined.

Title: A Method for Controlling Data Transactions
Inventor: GUTKIN IGAL
IPC: H04L1/18
Filed: 1997-04-16
Abstract: A data unit for transmission from station 16 is registered in a message handling table 22 along with an ID and transferred to the data link layer 17 for transmission. Periodically, a timer 19 is started and during the period of operation of the timer table 22 is inspected for the receipt of an ACK message from the receiving station 11. If an ACK has been received, the registration is cleared and the transaction is complete. If there is no ACK, a flag is set and the timer restarted. At the end of a second interval, table 22 is inspected, and if the flag is still "on", indicating that transmission of the data unit has not been satisfactorily completed, an operation is initiated to resolve the incomplete transaction. In this way, the system is not tied up waiting for an ACK message.

Title: A signal switch for transmit-receive switching of a portable telephone
Inventor: IVRISSIMTZIS LEONIDAS P
IPC: H04B1/48
Filed: 1997-05-22
Abstract: A broad-band low insertion loss switch 200 for use in transmit/receive switching in a portable telephone has a transmit port 202, a receive port 230 and an antenna port 214. In transmit mode a signal from port 202 is split between transmission lines 206 and 208 and recombined at port 214. Phase shifter 220 imparts a zero phase shift so that the split signals are in phase at port 214. Phase shifter 226 imparts a 180 degree phase shift so that signals travelling along lines 222 and 224 are out of phase and cancel at port 230 so that no signal arrives at the receiver. In receive mode phase shifter 220 imparts a 180 degree phase shift so that signals from port 214 split between lines 216 and 218 arrive at port 202 out of phase and cancel, whereas the signals arriving at port 230 are in phase and re-combine to form the received signal. Phase shifter 220 is described in detail and comprises microstrip lines coupled across a slotline. The switch has a multi-layer configuration and can be used over GSM and PCN frequencies. In satellite communications the antenna port 214 may be replaced by two arms of a bifilar or quadrifilar helix antenna.

Abstract: A high-accuracy inductive absolute position transducer system has two members (108,116) movable relative to each other and includes a code track transducer and may include a fine track transducer. The code track transducer includes a code track transmitter winding (180) and at least one set of code track receiver windings (178,179) (see eg Fig. 3). Each set of code track receiver windings includes n balanced pairs. Each balanced pair extends along the measuring axis and includes a positive polarity winding and a negative polarity winding. A code track has a plurality of flux modulator zones distributed along the measuring axis. Flux modulators are formed in at least some of the flux modulator zones. A signal generating and processing circuit (166) is connected to the transmitter winding and each balanced pair. The code track transmitter winding and each balanced pair form an inductive coupling. The flux modulators modulate the inductive coupling between each balanced pair and the code track transmitter winding based on the relative position between the read head member and the scale member (see eg Figs. 16-18). The flux modulators are distributed along the measuring axis such that each pair of adjacent flux modulator zones forms one of a set of output states in an overlying balanced pair. The pairs of adjacent flux modulator zones form a series of code elements extending along the measuring axis such that each set of m adjacent code elements forms a unique codeword. Each unique codeword defines an absolute position of the read head member relative to the scale member to a first resolution.

Patent GB-2333738-A (GB)
Title: Compression moulding a laminated article
Inventor: PURVES JAMES
IPC: F41H5/04
Filed: 1999-02-02
Abstract: A multi-layer article comprising a complex shaped stack of reinforced plastic layers is formed by compression moulding, the layers being fastened to one another prior to the application of pressure in the moulding process, so that lateral displacement of the layers is prevented. A stack of layers of material is impregnated with a thermosetting resin, and after the fastening together of the layers, the resin is cured by heating whilst the pressure is applied to urge the layers towards one another and compress the stack. Preferably, layers of dry glass cloth are layered in a mould cavity, the layers having been stitched together to produce a multi-layer laminate which fills the mould cavity, liquid thermosetting resin is injected, preferably under pressure, into the closed mould cavity, and finally heat and pressure are applied to cure the liquid thermosetting resin. This method may be used to produce a complex shaped article of variable thickness. The method is particularly suited to the manufacture of security panelling 11 for providing bullet-proof protection in premises which handle valuable items such as cash, since the method allows the formation of complex shaped articles without detracting from their ballistic performance. It may also be used in the manufacture of land, marine or air vehicles.
