Patent DE-3734492-A1 (DE)
Inventor: BOGNER MARTIN
IPC: A63C9/00
Filed: 1987-10-12
Abstract: The safety ski binding has a toe iron, arranged before a front sole plate (21), and a heel iron which exerts a forwardly directed thrusting force onto the toe iron via the inserted ski boot. The toe iron has a sole holder (16) which supports the front part of the sole (14) of the ski boot (15) at the front, the side and the top and can be swivelled counter to a spring force directed essentially towards the front in each case about one of two essentially vertically axes (17) of rotation provided on both sides of the vertical longitudinal centre plane (11). Provided on the sole holder (16) at the region situated between the axes (17) of rotation is a stop (18) which faces downwards and towards the front and interacts with a sloping surface (19), which extends from the top to the bottom and the rear and is fixed to the housing, in such a way that, when the ski boot (15) is inserted, its sole (14) holds the sole holder (16) counter to the resilient prestress directed downwards at a height, at which the stop (18) is situated at least at a slight distance from the sloping surface (19). The ski boot (15) is mounted on the ski (22) so as to be resilient downwards, by which means, in the case of a forward fall, a counter-force to the sole holder restoring force is produced which is dependent on the slope of the sloping surface (19) and the resilient prestress of the sole holder (16) towards the bottom.

Patent DE-3736142-A1 (DE)
Inventor: QUANTE HEINRICH
IPC: E21D11/15
Filed: 1987-10-26
Abstract: Lagging mats intended for use in the longwall gallery consist of interconnected longitudinal and transverse rods. The longitudinal rods have attachment hooks 15, 16 at the front and a transverse rod 7 protruding out of the plane of the mat, so that hook attachment is facilitated, at the opposite end. In the transverse direction of the mat connection parts 12, 13 are provided on the ends of the transverse rods, which render coupling to one another in the transverse direction possible. Thus the possibility is gained of producing a structure which as a whole is stable throughout, which is arranged and fixed between support system and rock and as a whole prevents the formation of caving-in and the like problems. <IMAGE>

Title: Jigsaw with stroke rod
Inventor: MEYER KLAUS
IPC: B23D51/16
Filed: 1987-11-07
Abstract: A plastic sliding link (5) is connected to the stroke rod (1) of a jigsaw. The sliding link (5) has sliding surfaces (11) which interact with guide surfaces (10) of the housing lid (9). Anti-torsion guidance of the stroke rod (1) and thus of the jigsaw blade (4) is thus guaranteed, a damping action in the face of hard impact stresses is obtained, and in the event of a fracture in the area of the sliding link (5) damage to further parts of the jigsaw is reliably avoided. <IMAGE>
Patent DE-3738021-A1 (DE)
Inventor: LEITL FRANZ DIPL ING
IPC: H05K9/00
Filed: 1987-11-09
Abstract: A computer bus comprises conductive tracks which extend in four layers. Each plug-in point (I, II, III) has three columns (a, b, c) of plug-in holes arranged in a plurality of rows (1, 2, 3, ...). The conductive track which links the plug-in holes having the index a2 in sequence passes between the plug-in points I and II through the first layer, but between the points II and III through the fourth layer. The same principle applies to the conductive track which connects plug-in holes diagonally adjacent to the plug-in holes a2 or the second holes thereafter. The conductive tracks which connect the adjacent holes to the plug-in holes a2 pass through the fourth layer when the conductive track connecting the plug-in holes a2 in sequence passes through the first layer, and vice-versa. This ensures that the conductive tracks starting from neighbouring holes are situated a maximum distance apart. The adjacent conductive tracks which pass through the same layer lead to non-adjacent plug-in holes, which results in minimal signal coupling. In addition, the alternation between the layers leaves sufficient space in each layer for a protective grid, which further improves the decoupling and shielding of the signals transmitted by the bus. Since the alternation of the conducting tracks between the layers is carried out according to the same principle, all the conducting trucks have the same length. This enables signals with identical transmission times to be obtained. A series inductance is also provided for each transverse capacitor in such a way that signals of different frequencies travel at the same speed.

Title: Method for reducing so-called pre-echoes in the transmission and/or storage of acoustic signals
Inventor: BRANDENBURG KARL-HEINZ
IPC: H04B1/66
Filed: 1988-02-29
Abstract: A method for reducing so-called pre-echoes in the transmission and/or storage of acoustic signals, and particularly of music signals via digital coding methods is described. The method according to the invention is distinguished by the fact that a "pre-echo condition" is calculated from the original signal and/or the reconstructed signal in a first step, and, in a second step, when the pre-echo condition occurs, the received signal is filtered in the unit in which the signal is reconstructed (so-called receiver of the coding method) in such a manner that the pre-echo is reduced or cancelled.

Abstract: A tank container, which is particularly suitable for relatively small tank volumes, has two triangular end frames (10), each of which is made up of two limbs (11) of equal length and a lower crossmember (12). The tank (15) can be connected directly to the frame assemblies (10) by means of end-side saddle structures (16) so that a frame underbody is not required. Provided at the tip of each end-side frame assembly (10) is a fixture (14) for the engagement of lifting tools. In this way, a lightweight frame construction is achieved; at the same time, the tank container is coupled at only two points to the respective lifting tool without there being any risk of tilting during raising. <IMAGE>

Patent DE-3824811-A1 (DE)
Title: Method for measuring the number of revolutions of a DC motor
Inventor: GRAEF DIETER
IPC: G01D5/242
Filed: 1988-07-21
Abstract: The invention relates to a method for measuring the number of revolutions of a DC motor. A simple method for measuring the rotational speed of a DC motor can consist in determining the number of current fluctuations at the armature winding. However, this method fails whenever the armature circuit is interrupted, because then owing to its inertia the armature still rotates further for a while without it being possible to measure current fluctuations. The object of the invention is to provide a remedy here. The solution of the invention consists in principle in that during or after the interruption of the armature winding the latter is short circuited, thus producing in practice a generator winding at which it is again then possible to measure current fluctuations or voltage fluctuations derived therefrom. The invention is particularly suitable for assigning the position of motor-operated subassemblies (modules) to specific counter positions. In addition, it is also possible to achieve that the motor brings the subassembly into a desired position by stipulating a specific counter position. <IMAGE>
