Patent DE-4221869-A1 (DE)
Title: Linear bar-indexing mechanism - has pre-loaded sliding and holding clamps released and engaged alternately by drive mechanism
Inventor: SCHULZE WALTER DIPL ING
IPC: B66F1/02
Filed: 1992-07-03
Abstract: The sliding bar etc. (26) is engaged by pre-loaded sliding (50) and holding (72) clamps. A drive mechanism (42) moves the sliding clamp in the travel direction (20) of the bar, engaging it with the bar in the process and releasing the holding clamp. At the start of the return stroke the sliding clamp is released and the holding one engages with the bar due to its pre-loading, preventing bar movement in the reverse direction. The clamps can hinge on axes (64,88) between the engaged and free positions. USE/ADVANTAGE - Highly accurate indexing in micrometer range.

Abstract: A buriable plastic cable duct element, usable as a walkway, to be arranged in particular along tracks, has a trough (1) with a U-shaped cross-section whose side walls (2, 3) are stepped at the trough edges. A lid (9) with a safely practicable horizontal surface safely usable as a walkway is laid on the trough edges, inside the trough. The trough (1) is made of thermoplastic material and its side walls (2, 3) are provided with ribs (31, 33).

In addition, the cable duct elements may be provided with macroporous, water-permeable bodies (23, 34, 40) preferably made of expanded polystyrene, but which can also be made of granulated plastics, a tangled yarn nonwoven or similar substance having the same effect. The water-permeable bodies are arranged at least on one side and under the bottom of the trough, approximately filling up the intermediate space between the earth and the trough (1). The water-permeable means, if required with additional draining mats, allow surface and/or ground water to flow away around the cable element, without the need to provide the cable duct with a corresponding drainage layer made of filtering gravel and/or fine sand. If required, stepped ribs for plant tubs and corresponding drainage elements may be arranged on the slope of the cable duct element.

Title: Rolling shutter door
Inventor: LAMSFUSS NORBERT
IPC: E06B9/58
Filed: 1993-06-16
Abstract: The object of the invention is to eliminate jamming of the terminating strip and likewise to eliminate jamming of intermediate strips, which are optionally arranged horizontally at vertical spacings for further reinforcing the door leaf, but to ensure sufficient bending strength against the wind pressure to which the door leaf is subjected. In order to achieve this object, the invention makes provision to subdivide the terminating strip and the optionally provided intermediate strips into two or three parts of approximately the same length and to connect the parts by resiliently elastic connectors of such bending strength that the connectors withstand the wind pressure to which the door leaf is subjected, virtually without deformation, but yield in a resiliently elastic manner to a relatively large transverse force. <IMAGE>

Title: Centrifugal motor having an external drive, without any fuel
Inventor: KAISER HEINRICH
IPC: H02K53/00
Filed: 1993-07-28
Abstract: The centrifugal motor having an external drive manages without any fuel and requires only lubricating oil. The main part of the motor - the rotor - is caused to move and is kept in motion with the aid of an electric motor. It is the centrifugal force which acts as the torque and is available as a type of drive. Its power depends on the torque of the rotor and thus on the magnitude of the speed of revolution. Attached loads need to be controlled individually since the centrifugal motor can be controlled only in a limited manner. It can be used in all areas of the motorised drive. Since the motor operates without any exhaust gases, the environment is not contaminated.

Title: Strip mill stand with roll gap control - by applying different bending forces in opposed directions to work roll journals
Inventor: STAHL WERNER
IPC: B21B13/14
Filed: 1993-09-15
Abstract: In a roll stand for a strip (esp. thin strip and foil) rolling mill, the novelty is that roll gap control, for strip thickness and flatness control, is effected by applying bending forces (P1-P4) of the same or opposite directions to the upper and lower work roll journals (10), each bending force having a magnitude different from that of the other force of the same pair and being applied at the opposite side and in the opposite direction to the corresponding bending force of equal magnitude. Pref. the roll gap control may be carried out using two identical force pairs (P1-P4), the forces of which are equal and opposite, and may be combined with additional axial displacement of the back-up rolls (5,6) wrt., the stand centreline in opposite directions and by the same or different amounts. ADVANTAGE - The stand has additional adjustment capabilities, thus reducing the number of requisite rolls with different contours, and provides more rapid roll gap control response to the continuously varying rolling conditions.

Abstract: Heater plug having a hollow body 1 in which a ceramic heating element 2 is arranged such that it projects axially at one side of the hollow body 1. The heating element 2 consists of a ceramic conductor 6 which is embedded in a ceramic insulator 7 and is connected to power supply terminals, that is to say to frame (ground, earth) via the metallic hollow body 1 and to a plug and socket connection 3.

The contacts are preferably under pressure, which is achieved by producing a bias between the components which are in contact. It is preferred to provide metallic contact parts, for example contact rings 10, 11 on the contact points between the contact surfaces 8, 9 and the metallic hollow body 1 as well as the plug and socket connection 3. <IMAGE>

Title: Machine tool
Inventor: NORRA WOLF DIETER
IPC: G05B19/19
Filed: 1994-02-18
Abstract: The invention relates to a machine tool, in particular a CNC milling machine, for machining in particular plate-shaped workpieces, having two slide guides which are arranged parallel to one another at a distance apart and on which the slides of the Y-axis are displaceable. Arranged on the slide guides of the Y-axis is a crossbeam bridging the gap and having the guide for the slide of the X-axis, on which one or more tools are arranged on slides with guides for the (perpendicular) Z-axis. To increase the milling capacity of such a machine tool known from the prior art, it is proposed according to the invention that, in an arrangement of two tools, a separate program-controlled X-spindle (14, 15) be allocated to each of these tools (10, 11), and that the tools (10, 11) be controllable independently of one another in opposite directions in the X-axis, preferably in mirror-image movement. On account of this control arrangement, the machining time can be halved for a large number of workpieces which mainly have mirror-image shapes. <IMAGE>

Title: Automatic motorway toll collection system
Inventor: SEPP GUNTHER DIPL PHYS DR
IPC: G07C5/08
Filed: 1994-05-06
Abstract: The motorway toll collection system automatically recognises vehicle speed and stationary time, storing data and calculating tolls due. Each vehicle (60) is fitted with an officially-calibrated device (100) with tachometer (70) with speed input (20).The local speed limit is acquired by the calculating unit, together with tolerance and minimum travel duration. The computer checks if the speed limit plus tolerance is exceeded over a predetermined number of distance markers on the motorway. The computer calculates the tolls due for the distance travelled, storing the amount with date/time, and charging the debit to an inserted pre-credited chip-card. The device is disabled on crossing the counting borders.

Title: Mixer tap for hot and cold water
Inventor: GLUNK GUENTER
IPC: G05D23/13
Filed: 1994-09-01
Abstract: The mixer tap has separate valves for the hot- and cold feeds and with a variable control to regulate the selected mix e.g. temperature of the outflow. The tap is operated by a pilot valve (40) which takes cold water from above the main valve and which controls the mechanically coupled valves for both feeds. If the cold water feed fails then the main valve cannot be opened. The pilot valve is fed via a non return valve (49) and is operated by a solenoid (20). It vents pressure from above a piston (35) in the main valve housing with the piston coupled directly to the two valves- the hot and cold valves. The control can be arranged to hold the tap open until the solenoid is operated again.
