Patent DE-4323837-A1 (DE)
Title: Automated high-speed rolls
Inventor: BUEDENDENDER GUENTHER DR ING
IPC: B21B1/18
Filed: 1993-07-16
Abstract: The invention for which an application is made is a rolling-process sequence for the production of hot-rolled bar and wire products in which semi-finished stock in the form of billets is rolled down by means of roughing-train assemblies to give a round rolled strand. The round rolled strand emerges freely at the exit side of the last roughing-train assembly. After the ends of the rolled strands have been removed, cross transfer of the round rolled strands to the feed roller table of the intermediate or main train is performed. A movable welding unit is installed on rails in the feed roller table of the intermediate or main train, the rails being arranged parallel to the feed roller table. After the first round rolled strand has entered the first rolling assembly of the intermediate or main train, the movable welding unit is clamped to the end of the emerging rolled strand. The following rolled strand follows the emerging rolled strand to the intermediate or main train via the roller table and is taken up by the welding unit accompanying the movement of the strand. The strands are then welded together by flash butt welding to give an endless strand. The welding flash formed during the welding process is then removed in a single pass. After the last forming unit of the rolling line, the finished rolled end product passes as an endless rolled strand through installed testing and measuring equipment and through the cooling stages before it is divided up and transported away as ring or bar stock. The entire rolling process is started at a relatively low speed and ... Original abstract incomplete.

IPC: B02C18/02
Filed: 1993-08-04
Abstract: The invention relates to a method for chopping and a chopper for comminuting organic waste. In this case, a cutter blade 1 is provided, the cutting edge 2 of which is moved on a first cam 10, and in particular from a first dead centre position 12, in which the cutting edge 2 is out of engagement with the material 7 to be chopped, towards a second dead centre position 13, in which a chopped section 9 is separated and back via a second cam 11 from the second dead centre position 13 into the first dead centre position 12. Preferably, both cams are of mirror-symmetrical design and form a drop shape. A roller 3 serves as counterholder. The supply takes place via a supply duct 5. The guide of the cutter blade 1 with its cutting edge 2 along the cams 10, 11 can be effected for example via a crank drive. Such a design and method result in a slow-running chopper which correspondingly generates low noise and requires only low power supply. <IMAGE>

IPC: E04B9/20
Filed: 1994-03-30
Abstract: The metal dowel (A) comprises a sleeve (3), an expansion cone (G), and a screw working in the cone and a tapped guide sleeve. The screw has a reduced-diameter portion (9) forming a fracture point, and the cone is at the end of the sleeve and tapped (24) to take the screw. There is an expansion head (E) with jaws (23), at the forward end of the screw, held in position by a distance-piece (F). On turning the screw, the jaws are pulled onto the cone and expand into the masonry etc. until the screw fractures. The front half (12) thus formed then holds the jaws engaged and joins the guide sleeve and the sleeve together via the tapped bore in the cone. The sleeve also joins the front half to the rear one (7). By further turning of the screw head (1), the front half acts via the guide sleeve so as to give linear adjustment (X) for levelling the anchored equipment (D).

Patent DE-4423978-A1 (DE)
Inventor: DOSTERT KLAUS PROF DR ING
IPC: H04B3/54
Filed: 1994-07-07
Abstract: For incoherent parallel optimal reception of m signal forms of different frequencies, an amplified and filtered reception signal (X) from the mains network is analog to digital converted and applied to a digital multiplier (6). A digital reference signal (Y) from a sample value memory (39) addressed by an address counter (35) is applied to the other input of the multiplier (6). 2m reference values Y corresponding to the in-phase and quadrature sample values of the m signal waveforms are allocated to each X value. The resulting products are accumulated in a ring structure of an adder (7), a bank of 2m registers and a switch (18) so that after a signal period, the in-phase and quadrature components of m signal forms for a data bit or a preamble are accumulated in the 2m registers. The switch (18) sends the results from the registers to a decision device (20-28) and the respective signal form energies are calculated. A shift operation is then carried out where the value of register (26) is copied into the other two registers (22, 27). The relevant differences for a chip decision are formed and provided for serial output on m output lines (29-33). The differences can be read by a microcontroller. On data reception, no read out clock is needed and only one bit is to be read on each line. The address counter (35) addresses the memory (40) containing the sample signal values. Frequency only changes in sync with the counter cycle guaranteeing phase continuity with signal synthesis. <IMAGE>

Title: Training gate for horse jumping
Inventor: KASTL HEINER
IPC: A63K3/04
Filed: 1994-08-11
Abstract: The training gate has adjustable bars (3,4,5) between two uprights (1,2). A height adjustable light gate (6,7,8) is set at selected heights above the top bar and activates an acoustic signal, in a loudspeaker beside the gate, when the light beam is broken. The type and amplitude of the acoustic signal is selected by the trainer as being the most effective for the particular horse being trained. Leg guards for the horse can be fitted with a simple receiver and shock electrodes controlled by a processor. These provide controlled electric shocks on the appropriate leg and train the horse not to drag a leg. The shock level is set well below that which is liable to harm the horse.

Title: Device for measuring the fuel consumption of an internal combustion engine
Inventor: RIESENBERG KLAUS
IPC: G01F9/00
Filed: 1982-03-31
Abstract: Device for measuring the fuel consumption of an internal combustion engine, of which the fuel supply system is provided with a circular line for cooling the fuel pump. During the measuring of the consumption, said line is shortcircuited upstream of a flowmeter arranged in the supply pipe, so that only the fuel amount brought to the engine transverses the supply pipe coming from the tank and therefore the flowmeter as well. For overheating reasons, the shortened fuel circuit is used only when a measurement is desired. For the switching of the fuel return conduit, a 3/2 way valve is used in the exemplary embodiment.

Title: Pestle-type grinder
Inventor: SIJSLING PETER
IPC: B02C19/08
Filed: 1985-08-14
Abstract: The problem of pestle-type grinders, in particular for laboratory use, which are fitted with a container for receiving the grinding material in which a pestle is movably arranged as a grinding element, and with a drive system for the pestle, is essentially that, because the pestle is held and guided during the grinding process on a holding device which extends through the cover of the grinding container, it is impossible to have a fully closed system. To solve this problem it is envisaged that, while the grinding container (17) remains stationary, the drive force is transmitted to the pestle (20) in a magnetic manner.
