Abstract: A box for storing social games having the form of a book and comprising two symmetrical parts forming the covers of the book which are articulatedly mounted on one another by hinges. The box is movable between a closed position and an open position. When the box is in the open position, the symmetrical parts are positioned one adjacent the other on one plane so that game pieces can be placed thereon. When the box is in the closed position, each symmetrical part is pressed against the other and a male component is provided having a salient portion which forms the back of the book. The two symmetrical parts forming the covers of the book form a female component of the book which is further provided on the side of the hinges within an aperture into which the salient portion of the male component can be inserted to secure the box in the closed position.

Abstract: A photosensitive electrophoretic display device is described which provides real time imaging without a reset cycle. This display device operates by the use of interdigitized electrodes at an addressing side of the display on which a photoconductor material having a varying resistance according to light exposure is provided in order to vary the electric field across the electrophoretic suspension. This enables movement of electrophoretic particles according to application of the proper voltages and light exposures.

Abstract: Apparatus and method for evaluating the likelihood of a word In a vocabulary of words wherein a total score is evaluated for each word, each total score being the result of combining at least two word scores generated by differing algorithms. In one embodiment, a detailed acoustic match w6rd score is combined with an approximate acoustic match word score to provide a total word score for a subject word. In another embodiment, a polling word score is combined with an acoustic match word score to provide a total word score for a subject word. The acoustic models employed in the acoustic matching may correspond, alternatively, to phonetic elements or to fenemes. Fenemes represent labels generated by an acoustic processor in response to a spoken input. Apparatus and method for determining word scores according to approx- mate acoustic matching and for determining word scores according to a polling methodology are disclosed.

Abstract: The main patent proposes electrical switchgear in which multi- position isolating switches (I, II) are provided instead of load or power switches in each inlet and outlet. Moreover, a normally closed coupling switch (8) is located in the switch gear between a main and an auxiliary busbar (10, 11), which coupling switch carries out the switching on or off in accordance with a switching command acting on both switchgear for each switching operation, synchronously with the multi-position isolating switch of the relevant inlet or outlet. In order to make the sequence of switching operations independent of the scatter and alteration of the inherent times of the two switchgear, the switching command acts on the drive of the respective multi-position isolating switch (I or II) while the operation of the coupling switch (8) is derived from the drive movement of the multi- position isolating switch (I or II). <IMAGE>

Abstract: In a microprocessor video display system a pixel-mapped video memory (10) can be accessed both by the CPU (12) and by video display logic (14) which delivers video data to the display. Contrary to accepted practice, contention between simultaneous access requests from the CPU and video display logic is avoided by the video display logic deferring its access request for one video memory access period. This is acceptable because: the video control logic can access data at a rate twice that required by the display, the video memory access cycle rate is the same as the CPU clock rate, and the microprocessor accesses the memory for one clock period during operation cycles lasting three orfourclock pulses. The CPU operation is thus kept at its maximum speed without the video data being adversely delayed.

Abstract: An electrophotographic printing machine in which an electrostatic latent image recorded on a photoconductive member (10) is developed with a liquid developer material (32) having at least a liquid carrier with marking particles dispersed therein. The liquid developer material is advanced on a roll (28) from a supply thereof to the latent image at a development zone (72). Marking particles are moved through the liquid carrier onto the surface of the roll and a resilient blade (40) removes excessive liquid developer material from the roll prior to the development zone. The density of marking particles deposited on the roll is increased by means of an electrode (36, 74) positioned adjacent the roll within the supply of liquid developer material.

Abstract: A coaxial cable coupler includes a first section (12) for coupling to the coaxial cable (50) of a utilisation device and a second section (14) for coupling to the coaxial cable (44) of a communications system. Both the first and second sections (12,141 are provided with cavities (18, 20) therein. The cavity (20) in the second section (14) houses an insulating sleeve (22, 24, 28) which in turn encloses a contact assembly (36,38) for making contact to and electrically connecting the inner conductors (48, 54) of the coaxial cables of the communications system and utilisation device. The first cavity (18) is dimensioned and configured to function as a waveguide having a cutoff wavelength which is substantially below the operating wavelength spectrum of the system, establishing a very deep bidirectional high pass filter at the open coupler. Thus, when the utilisation device is disconnected, radiation from or to the coupler is prevented thus preventing environmental electromagnetic pollution and unauthorised wirelsss access from and to the system.

Abstract: A method for producing cutting tools and a blank produced according to the method for machine blades made of hot-rolled flat steel with a sloping surface forming the cutting edge. The aim is to increase the service life of these machine blades and to reduce the production costs. This is achieved in that a flat profile is rolled as a trapezium- or parallelogram-type profile, in which case, on the sloping surface resulting in cross-section in an acute angle to the side surface, the roll tab, forming due to overfilling of the roll groove in the final pass to form the finished profile, forms a homogeneous material structure in the region of the cutting edges.

Abstract: Known screen printing machines, which have a continuous support for the squeegee, have the disadvantage that the printing is impaired when the support bends. This also applies to constructions with a squeegee support which is independent of the support and the weight of which, in the case of an asymmetrical squeegee arrangement, results in an uneven loading of the squeegee. According to the invention, the support is therefore disposed rigidly at the guide rails, and pneumatic double-action cylinders are arranged directly at the support, the squeegee being fastened at the cylinders so that its angle can be adjusted. A bending off the support does not influence the printing quality, even if the squeegee is not arranged in the center of the support.
