Abstract: A vacuum-type cleaning apparatus and a cleaning method employ a cleaning head which is mounted on a housing and which has an intake opening that is adapted to be juxtaposed with contaminated portions of an object to be cleaned. A suction force is generated and transmitted via a suction channel through the intake opening and thereby to the object. Nozzles inject a stream of cleansing fluid into the channel and its flow is directed towards the intake opening and at an angle relative to the plane of the intake opening so as to impinge the object prior to the removal of the contaminants entrained in the stream from the object by suction. The flow is directed by a baffle which is inclined transversely of the plane of the intake opening, preferably at an acute angle. The baffle is mounted within the channel and provides for a dry cleaning zone to pick up loose contaminant particles prior to contact being made by the stream of cleaning fluid in the wet cleaning zone.

Abstract: The disclosure relates to the computer art in general, and in particular to an identification device of the key-board type which includes a rectifier for both supplying current to the device and for supplying a trigger signal to a pulse generator having several outputs. Upon receipt of the trigger signal, the pulse generator generates a predetermined sequence of pulses on its outputs which are connected to a combination circuit which has two outputs. The pulse generator is operative to generate a train of pulses, each pulse of the train being applied to a respective one of the outputs as a function of a code which identifies the device. The pulses appearing at these two outputs are inductively transferred to a detector which thus receives a pulse train containing a predetermined number of pulses, the polarity of each of the pulses being representative of a binary number constituting the identification code of the device.

Abstract: The device possesses a supply chamber (10) having at least one inlet channel (8) and a filter chamber (11) communicating with the supply chamber (10) via a passage (14). An outlet chamber (17) is connected to the filter chamber (11). A first membrane (6) under tension is located in the supply chamber (10) and covers the passage (14) between the supply chamber (10) and the filter chamber (11) until the liquid pressure prevailing in the inlet channel (8) has reached a specified magnitude. The inlet channel (8) and the passage (14) open into the supply chamber (10) on the same side of the first membrane (6). The outlet chamber (17) houses a second membrane (7) which subdivides this chamber into two separate parts which are connected via a bypass channel (31). There are control devices (29) for adjusting the flow cross-section of the bypass channel (31). An outlet channel (30) is connected to that part of the outlet chamber (17) which lies downstream from the diversion channel (31). The second membrane (7) can be moved toward the outlet channel (30) and away from the latter in order to control the amount of liquid flowing through it as a function of the pressure differential prevailing between the two separate parts of the outlet chamber (30). The device permits precise control of liquids for intravenous administration. <IMAGE>

Abstract: Each of the scrapers to be arranged at two discharge ends of a reversible belt band (3) has a support (8) which holds a plurality of scraper elements resting under spring pressure against the underside (4') of the belt band. Each scraper element consists of a cutting piece (21) and a spring apparatus (17, 18, 19) which acts in two directions and has a pivot mounting about an axis (A) for the cutting piece (21). In its operating position, the support (8) is so arranged relative to the underside (4') of the belt band that the distance (h) of the axis (A) from the underside (4') of the belt band is shorter than the connection between a cutting edge (23) of the cutting piece (21), resting against the underside (4') of the belt band, and the axis (A). The spring apparatus (17, 18, 19) permits the cutting edge to make contact in each case at a short distance (a) before or behind the bottom point of the perpendicular dropped from the axis (A) onto the underside (4') of the belt band, depending on the direction of movement of the belt band (3). As a result, a high, constant scraping performance, with the gentlest possible treatment of the belt band, and a simple change-over of the scrapers from the active to the inactive position and vice versa can be achieved. <IMAGE>

Abstract: A heat exchanger for gaseous media is formed from planar and folded sheets, which are piled above each other. Every other sheet is planar and every other sheet is folded. The folded sheets are orientated such that the longitudinal direction of the folds of two adjacent folded sheets forms a right angle between each other. In order to simplify the manufacture of a heat exchanger, a planar and a folded sheet are united with each other prior to piling. The present invention implies that a folded strip 4 and a planar strip 2 are each pulled out from their respective magazines 3 and 1, respectively, so that both strips are parallel to each other and covering each other. The parts of both strips 2 and 4 covering each respective other are pressed together by means of pressing tools 13A and 13B such that a planar band 14 is achieved, which is parted at its middle by means of a cutting tool 15, 16. The edge zones 17 and 18 hereby created are divided into two longitudinal parts by means of a forming tool 19, 20 and 21, whereby the edge zones obtain an inner part 24 and 26 lying in the same plane as the planar strip 2, and an outer part 25 and 27 which is directed upwards and perpendicular to the inner parts 24 and 26. By means of another forming tool 28 and 29, the upwardly bent parts 25 and 27 are folded at their outermost ends such that outwardly directed flanges 30 and 36 with a good abutment surface against an overlying planar, disc-shaped element are obtained. <IMAGE>

Abstract: A laminated packing material with a sterile surface which is protected by a protective layer joined detachably to it. On rolling-up of the material web to a roll after its manufacture the turns forming the roll are joined to one another by means of an adhesive, which means that the roll will be wholly "tight" and consequently simple to handle during transport and storage without any danger of infection. When the laminate web is to be converted to packing containers, the turns forming the roll are separated from one another between the protective layer and the sterile surface on unwinding so that the unwound material obtains two outer sterile surfaces.

Abstract: An accessory for use in pricking depth-indicating washers on to dental reamers comprises a body constituting a receptacle. The washers which are located in the receptacle are brought into a free space of the body within which they are juxtaposed. They successively engage a notch in a movable small plate, constituting a distributor element, which enables the washer located in the notch, by transverse sliding of the small plate, to be brought opposite to a hole of the body. The washer thus placed can easily be pricked by a dental canal reamer passing through a hole provided in the cover of the accessory and which is situated opposite to the hole of the body. The diameter of this hole is greater than that of the washers to allow the washer which is pricked on the spindle to be withdrawn from the receptacle.
