IPC: H04L12/28
Filed: 1987-12-10
Abstract: Transmission-reception equipment for a bus system and for handling access collision of subscriber stations connected dc-free in a bus system preferably constructed with a shielded twisted-pair cable. The transmission-reception equipment of the subscriber stations at their transmission sides, has a difference bus transmitter unlocked for only a fraction of a bit time span and thereby outputting a difference voltage pulse of one the other operational sign but placed in a quiescent condition in the remaining part of every bit time span. At the reception side of the subscriber stations, two difference bus receivers are connected to the bus signal conductors, oppositely in comparison to one another, and a bi-stable RS flip-flop has its inputs connected to outputs of the difference bus receivers.

Abstract: The accelerometer is installed with it longitudinal axis aligned at least approximately with that of the vehicle. The mass sliding along a pivot is urged rearwards by the spring whose tension is overcome in the event of any sudden slowing by the inertia of the mass. Forward movement of the mass bridges two contacts wired to a circuit board carrying an adjustable delay circuit. The deceleration threshold is adjustable by rotation of a knob geared to the threaded end of the pivot to vary the deg. of compression of the spring.

Abstract: The invention takes the form of a mask resting on the experimenter's face, covering the eyes and nose. The apparatus enables removable, coloured, translucent screens (1) to be visualised in mono- or binocular vision by means of a removable internal partition (4). The portable model permits only monocular vision produced as a result of the partition (1). Respiration using the apparatus is carried out via orifices (2) pierced in the mask; one or more loudspeakers (3), integral with the apparatus, enable vibratory energy complementary to the coloured area contained in the apparatus to be introduced. The front of the mask of the portable model possesses a slide channel enabling two opaque half-screens (2), perforated to incorporate translucent coloured chips (3) whose colours are suited to the desired objective, to be brought into position. The half-screens (2), which are movable in respect of their spacing, permit visual superposition of chips of identical colour on each half- screen by binocular mental construction of the phenomenon of vision. This device, bringing about recentering of the eyes, enables the cosmic energy conveyed by the coloured chips (3) to be absorbed symmetrically by the energy centre of each eye. <IMAGE>

Abstract: A method and apparatus for hemodialytic ultrafiltration utilizing a dialysate flow path (10), a hemodialyzer (24), a first receptacle (20) and a second receptacle (40). Fresh dialysate is supplied to the first receptacle (20) and spent dialysate is withdrawn from the second receptacle (40) at substantially the same rates. The method requires variably withdrawing fresh dialysate from the first receptacle (20) and supplying same to the hemodialyzer (24), and variably withdrawing spent dialysate from the hemodialyzer (24) and delivering same to the second receptacle (40). The dialysate levels in the receptacles are maintained at relatively constant, pre-determined levels. A controlled amount of dialysate is withdrawn from the dialysate flow path between and including the receptacles to thereby effect a withdrawal of ultrafiltrate from a patient's blood into the flow path to substantially balance the amount of dialysate withdrawn therefrom.

IPC: H02J7/34
Filed: 1988-05-09
Abstract: By providing an electrical appliance, such as a hand tool, with a separate battery unit, the capacity of such a battery unit can be substantially enlarged in comparison with appliances wherein the battery has been located in the housing of the appliance. By using a voltage of an inter­mediate level, i.e., about a magnitude of about 50 V, cur­rents are reduced so that a relatively thin conductor between the appliance and the battery unit will be sufficient. Conse­quently this conductor does not impede the user of the elec­trical appliance. Further - in comparison with the mains voltage - the requirements for and consequently the thick­ness of the insulation is considerably less. Further a mains supply unit is provided which can both be used for loading the battery unit and for supplying electrical energy to the appliance.
