Patent DE-3742941-A1 (DE)
Inventor: EILENBERGER GERT DR ING
IPC: H04L49/111
Filed: 1987-12-18
Abstract: Data containing traffic volume statistics are preferably transmitted in packet form with packets of equal length via virtual links. In a packet switching device, it is essentially possible that two or more packets may arrive simultaneously from different lines but are intended to be forwarded along the same line. 
<??>For this reason, buffer memories must be provided, in which the packets which cannot be forwarded immediately are queued. The memory capacity required for this purpose depends not only on the length of the packets but in particular on the number of converging lines, the type of traffic volume and the transmission quality required. In known packet switching devices, around 80% of all the chip surfaces are used within the switching network for these memories. 
<??>According to the invention, a fixed number of packets are combined within the exchange in each case to form a frame, all packets are divided into packet parts of equal length and are distributed among sub-frames. Switching is carried out on the basis of sub-frames using synchronous time-division multiplexing. The memory space required in the switching network is reduced by the frame : sub-frame ratio. The memories used are those which are required in any case for synchronous time-division multiplex switching.

Title: Device for monitoring high-frequency (radio-frequency) electric leakage currents
Inventor: HILL THOMAS
IPC: A61B18/12
Filed: 1988-07-22
Abstract: A device for monitoring high-frequency electric leakage currents is described, which flow during high-frequency surgery from a body into an operating table which is connected to a protective circuit (protective-conductor system) and/or an equipotential bonding conductor system. Via two measuring circuits which are connected to two different points on the protective circuit and/or the equipotential bonding conductor system, a voltage drop caused by a leakage current on the basis of the impedance of the protective conductor or the equipotential bonding conductor is detected and converted using a voltage transformer into a signal which is proportional to said voltage and is fed to a voltage comparator in which it is compared with a reference signal determined by calibration taking account of a maximum permissible limiting value level for the leakage current. It is possible with the aid of such a device for monitoring leakage currents to establish precisely the level of the leakage current independently of the electrical installation of the operating table.

Title: Method of producing a capillary dialyser and capillary separators
IPC: B29C39/24
Filed: 1988-08-13
Abstract: In the production of capillary dialysers for haemodialysis with distribution of the casting compound at the ends of the capillary bundle 90 by centrifugation, a displacement liquid 160 which has a higher specific weight than the casting compound and is not miscible or reactive with the latter, is included in the centrifugation process, and this forms a layer into which the ends of the capillary tubes 110 project on the bottom 50 of the cylindrical housing 100. The capillary bundle 90 need not be cut off. The ends of the capillary tubes 110 have no ridges but remain open (Fig. 5). In the production of capillary dialysers the ends of the capillary bundles 90 are sealed relative to the surrounding housing 100 by means of a casting compound 160 which is applied by centrifuging the housing 100 about an axis 140. In order to apply the same amount of casting compound 160 to both ends of the housing 100 to avoid unbalanced masses, the metering aid 200 is provided with two identical metering chambers 250, 260 from which the identical amounts of casting compound 160 present therein can be transferred to the housing 100 of the capillary dialyser via overflows 330, 340 at the start of centrifuging. <IMAGE>

Patent DE-3840748-A1 (DE)
Inventor: BARTRAM HERBERT DIPL ING
IPC: B66F9/07
Filed: 1988-12-03
Abstract: In a device for moving fork arms (1) into an upwardly inclined supporting position on a lifting and transporting device (2), the fork arms (1) are mounted on a lifting frame (3) and are swivelled about a horizontal axis (4) into the inclined supporting position by a power-driven traction and swivelling device (5) which is actuated when the fork arms are loaded but before the lifting frame effects the lifting movement. The fork arms and their load are then raised in the same inclined position by the traction and swivelling device (5) with the lifting frame (3). The traction and swivelling device (5) is arranged in the lifting frame (3) and has a point of application (8) of the traction in the form of a pulley and a fork arm pivot in the form of at least one eccentric, wedge or hydraulic cylinder which acts on the fork arms (1). The traction and swivelling device (5) is spring loaded and the unloaded fork arms (1) lie in a horizontal initial position and move automatically against the spring with respect to the lifting frame (3) for a limited distance until the fork arms swivel.

Title: Electrical power supply system for motor vehicles
Inventor: BALL WILFRIED
IPC: H02J7/14
Filed: 1988-12-23
Abstract: In order to supply the on-board network, the electrical power supply system has an electrical generator (6) which can be driven by an internal combustion engine (7). The generator (6) is driven by an internal combustion engine (7) which is independent of the traction engine of the motor vehicle and supplies sufficient energy to the on-board network whenever the vehicle battery power supply is no longer adequate because of a large number of electrical loads. The generator (6) and the independent internal combustion engine (7) are arranged in the rear end of the motor vehicle, to be precise in the spare-wheel recess (3). This results in a favourable axle-load distribution, since the weight of the generator is taken away from the front axle and the rear axle is essentially loaded by both the weight of the generator (6) and the weight of a small, independent internal combustion engine (7). <IMAGE>

Patent DE-3918986-A1 (DE)
Title: All-wheel steering system for motor vehicles
Inventor: TISCHER WERNER
IPC: B62D7/14
Filed: 1989-06-10
Abstract: An all-wheel steering system has an actuator motor (10) for the rear wheels, which actuator motor (10) contains on a piston rod (24) two fixed working pistons (25 and 25A) and two displaceable control pistons (27 and 27A) in an intermediate housing section. The working pistons (25 and 25A) form together with the control pistons (27 and 27A) control spaces (28 and 28A) which are continuously connected to the pump (2). A pressure chamber (33) in which a spring element (34) acts on the control pistons (27 and 27A) is located between the control pistons (27 and 27A). The pressure chamber (33) can be blocked by means of a 2/2-way valve (37) which is controlled by means of a switching device (17) or can be connected to a tank (3). In the operating position of the rear-wheel steering (11), the two control pistons (27 and 27A) are in contact with a sleeve (35) by means of the pump pressure which is applied to the control spaces (28 and 28A). The piston rod (24) is then freely movable in both steering directions. In the event of a drop in pressure in the control spaces (28 and 28A) as a result of a fault in the hydraulic circuit, the 2/2-way valve switches over and the control pistons (27 and 27A) move under the force of the spring element (34) against shoulders (36 and 36A). In order to decelerate the restoring movement, the control pistons (27 and 27A) push the oil located in the control spaces (28 and 28A) into the tank (3) via an orifice. In this way, the rear wheel steering (11) is locked in the straight-ahead position (Fig. 2). <IMAGE>

Title: Gas partial pressure sensor - with threaded parts with hard and soft sealing contact portions
Inventor: GRISARD KLAUS DR
IPC: G01N27/49
Filed: 1989-07-06
Abstract: Sensor, for gas partial pressure determn. in water, has a cathode (2), the tip of which is exposed in the roughened convex measuring face (3) of an insulator (1) in an electrolyte space (11) covered by a membrane (9) in close contact with the measuring face (3), the insulator (1) being part of an externally threaded inner body (4) onto which is screwed a sealing ring (8) which surrounds the insulator (1) to form the electrolyte space (11) and which supports the membrane (9) so, on screwing tight, the membrane (9) is stretched over the measuring face (3). The novelty is that sealing of the electrolyte space (11), at the threaded region between the inner body (4) and the sealing ring (8), is effected by annular sealing contact made, during screwing together of these two parts, between a blunt 90 deg. edge (12) of relatively hard material on one of the parts and a planar face (13) of relatively soft material on the other part. Pref. the edge (12) is of metal and the face (13) is of polypropylene. USE/ADVANTAGE - Useful for pO2 determn. and determn. of concn.  of other gases (e.g. NH3, CO2 or H2S) in aq. solns.  A well-defined membrane seating on the measuring face is ensured by simple screwing together of the inner body and the sealing ring.
