Title: Quick-clamping device for clamping rotary tools to a machine spindle
Inventor: DUENNER KLAUS DIPL ING
IPC: B23B31/18
Filed: 1983-01-25
Abstract: A quick-clamping device for clamping and securing the position of rotary tools for machining materials, in particular wood, plastic or light-alloy materials, has clamping elements by means of which the tool (16) can be pressed by means of a bearing face (19) against a clamping face (22) formed on a main body (1) which can be secured on the associated machine spindle (3) and situated in a plane perpendicular to the axis of rotation (21) of the said main body. The clamping elements are designed as clamping levers (23) which are pivotally mounted on the main body (1) in such a way that, when the latter rotates, they pivot radially outwards due to the centrifugal force. The ends of these clamping levers (23) form retention fingers (29) in the form of radial projections which press against oblique faces (34) of the tool (16) under the action of centrifugal force in order to produce an axial force which presses the tool (16) against the clamping face (22). <IMAGE>
Patent DE-3303386-A1 (DE)
Inventor: SCHOLZ HEINRICH
IPC: B22D11/128
Filed: 1983-02-02
Abstract: A roller guide for use in a continuous casting installation for steel is divided into segments. Each segment includes a fixed guide member which rests on a base and a movable guide member which is supported by the fixed guide member. The guide members carry rollers which cooperate to define a path for a continuously cast steel strand. The fixed guide member has a series of hollow columns which are aligned with respective tubular elements provided on the movable guide member. Spacers for adjusting the distance between the rollers are disposed between the columns and tubular elements. A tie rod extends through each column and has a first end located externally of but adjacent to the respective column. The first end of each tie rod has a passage which registers with a corresponding passage in the base. Each pair of registering passages receives a locking pin. The locking pins connect the tie rods to the base and indirectly connect the fixed guide member to the base via the tie rods. Each tie rod has a second end located in one of the tubular elements of the movable guide member. A compression spring in each tubular element reacts against the associated tie rod and against the movable guide member thereby urging the movable guide member towards the fixed guide member. The action of the compression springs also causes the locking pins, and hence the fixed guide member, to be braced against the base. A piston-and-cylinder unit mounted inside each tubular element is arranged to act against the adjacent end face of the associated tie rod counter to the respective compression spring.

Title: Sheet piling lock
Inventor: WOLF HANS-PETER DIPL ING
IPC: E02D5/08
Filed: 1983-03-01
Abstract: In order to eliminate special corner profiles in sheet pilings, the sheet piling lock is designed in such a way that either the wall continuing straight or a branch at right angles can be produced with the same plank. This is achieved when the sheet piling lock is designed to be symmetrical to an axis which is rotated by 45 DEG relative to the wall axis. The said sheet piling lock can be used for all planks. An example of the sheet piling lock is shown in Fig. 1. <IMAGE>

IPC: H04L25/49
Filed: 1983-05-13
Abstract: 1. A method of decoding an nB/(n + 1)B-coded serial data flow (DIAM 1) which comprises bit groups each comprising n signal bits and one coding bit, characterised in that the data flow (DIAM 1), which need not possess any frame structure or bits characterising the frame structure, is then monitored to determine whether and how frequently impermissible bit groups occur in which (n + 1)/2 signal bits have the logic value 1 and simultaneously the bit which occurs at the location specified for the coding bit (DIAM 11) has the logic value which indicates an inversion of the n signal bits (DIAM 12 to DIAM 18), and that an occurrence of these impermissible bit groups which exceeds the fault probability is evaluated as asynchronism of the decoder and initiates the synchronising step.

Title: Method and device for controlling the position of a throttle in the intake pipe of an internal combustion engine
Inventor: NITSCHKE WERNER
IPC: F02D11/10
Filed: 1983-07-29
Abstract: A method and a device are proposed for controlling the position of a throttle (35) in the intake pipe (36) of an internal combustion engine, the throttle (35) being first run into the closed position (39, 40) for a fixed period when the internal combustion engine is switched off and then opened again (41). In addition, after switching off the internal combustion engine the current supply for a suitable electronic control unit (11) is still maintained by way of a timer element (14, 17 to 20). In this way the internal combustion engine is reliably switched off without any ensuing, uncontrolled combustion processes and due to the subsequent re-opening of the throttle (35) any tilting or jamming in the subsequent cooling process is avoided. The timer element also brings about reliable shutting-off of the movement of the throttle (35).

Title: Cast running wheel
Inventor: BUERK WERNER
IPC: B60B1/08
Filed: 1983-09-14
Abstract: In the case of a running wheel, the spokes are cast with the rim in one piece. At the end facing the hub, the spokes are provided with tensioning heads which - separated from one another by separating joints - enclose the hub as a ring and are positively fixed in the circumferential direction with respect to the hub, whereas in the radial direction they have a clearance with respect to the hub. The spokes are tensioned by means of a tensioning device which is arranged between the tensioning heads and the hub and is suitable for exerting a radially inwardly directed tensioning force on the spokes. The cast body may consist of metal, in particular aluminium or titanium, but also of plastic, for example fibre-reinforced polyamide or carbon-fibre-reinforced plastic.

Title: Brush for surface treatment having wire bristles
IPC: B24D13/10
Filed: 1983-10-19
Abstract: The brush for surface treatment is constructed, in particular, as a grinding and polishing brush in the form of a round or end brush having a support (3) seated on a spindle (2) and having a bristle arrangement (4) made of steel, brass, copper or the like, which is directed outwards from said support or forwards in continuation of the spindle (2). The bristle arrangement (4) is fitted at least partially with grinding agents, such as diamond dust or diamond shavings, and can have electroplating (6) made of copper or the like as substrate for the grinding agent or can be pre-copper plated. The diamond dust or diamond particles (5) are applied to the wires of the wire arrangment (4) or to their additional coating (6) by means of an electroplating bath. The polishing and grinding effect of brushes of this type can be varied to a great extent solely by different contact pressure on the surfaces to be treated, the use of grinding and polishing agents additionally being greatly reduced and the service life of such tools being increased considerably. <IMAGE>

Title: Hydraulic valve control with adjustable control times
Inventor: RIEF CORNEL
IPC: F01L9/11
Filed: 1984-01-02
Abstract: This method of hydraulic valve control enables engines to be designed which have a more favourable power characteristic as a result of improved cylinder filling over a very wide rotational-speed range, up to a very high rotation speed. This results in weight, stroke space, fuel and motor-vehicle control savings. Since the maximum torque can now be produced over a wide rotational-speed range, a two-gear transmission can be used. Possible fields of use are:     - aircraft engines   - motorcycle engines   - racing engines - sports vehicle engines th
