Title: Safety drive with clamping protection for the movable step
Inventor: PIETROWSKI EDMUND ING GRAD
IPC: B61D23/02
Filed: 1984-03-14
Abstract: Safety devices are provided at the entrances of rail-bound vehicles to interrupt the drive circuit for the movable step or the automatically closing door when a movable step is subjected to load. The design of the safety device according to the invention is intended to achieve the spatial combination of the safety device and the drive of the movable step, which have hitherto been spatially separated, to form a discrete structural unit, to permit rapid assembly. This is achieved by arranging a flange on the casing perpendicular to the shaft, the slot of which flange accommodates a pin which is attached to the fixed part of the entrance or the vehicle and is elastic to a certain extent, the longitudinal axis of the slot extending radially in relation to the shaft and the casing being secured against twisting by means of a spring.

Patent DE-3419986-A1 (DE)
Title: Safety device for liquid-gas tanks
IPC: F17C13/12
Filed: 1984-05-29
Abstract: The pressure-relief valve (13) provided on the tank (10) can be opened by the pressure of a control line (32) even if its response pressure is not reached. The control line (32) is connected to a pressureless outlet line (16) or to a pressure source via a series circuit consisting of a valve (19), which reacts to temperature increases in the tank (10), and a temperature-dependent shut-off member (20) which reacts to fire temperatures in the vicinity of the tank. If a fire occurs, the temperature, liquid level and pressure in the tank (10) increase, and the shut-off member opens due to the increased outside temperature. The series circuit causes gas to be released only if both conditions are met. The normal function of the pressure-relief valve (13) is not impaired. It is possible to fill the tank (10) up to the maximum filling level of 98% of the tank volume without having to fear that the filling level of 98% will be exceeded in the event of fire. <IMAGE>

Title: Selection detent in a gear-shift device
Inventor: HEINZELMANN KARL-FRITZ DIPL IN
IPC: F16H61/24
Filed: 1984-09-04
Abstract: Selection detent in a gear-shift device on or in connection with a rotary shaft (2), upon the axial displacement of which in the neutral position one slot is selected and upon the rotation of which the gears are shifted. Arranged in the rotary shaft or on at least one notched ring (3) are notch tracks (31, 33) which act only in the selecting direction and interact with at least one detent element (1) guided in the selector housing (4). Under the action of a spring (6) which is supported against the selector housing (4), the detent element is pressed towards the notch track (31), with the result that, under the action of the notches, a notch ridge is formed which makes it easier for the driver to find the slots when shifting the shift lever. Under the additional action of a recoil spring assembly (7), the shift lever is guided back into predetermined slots, the detent element or preferably detent elements are of pivotable design, being designed, for example, as detent levers (1), and are mounted on a first pin (5) fixed in the selector housing (4) transversely to the rotary shaft. A nose (11) of the detent lever (1) is in operative connection only with the notches of one detent ring and the detent lever is limited in its pivoting movements in such a way via a second pin (5A), arranged parallel to the first pin, in a recess or a slot (12), that a gap (81) is formed between the nose (11) and the base of the notch track (31, 33) or rotary shaft (2). Due to the low friction during the ... Original abstract incomplete. <IMAGE>

Patent DE-3445099-A1 (DE)
Title: Precast concrete member
Inventor: NEUMANN HERWIG
IPC: E02D29/02
Filed: 1984-12-11
Abstract: Single-storey precast concrete member for a retaining wall or space-lattice wall in which plants can be grown, with a front and a rear longitudinal beam (10 and 14 resp.) which are connected to one another at a distance apart between their ends by cantilever sections (18, 19). In order to manage with fewer structural units and less laying work when erecting the wall and at the same time improve the planting and sound absorption, the perpendicular distance between the top and bottom continuous support surfaces (28 and 30 resp.) of the cantilever sections (18, 19) is at least three to four times as great as the parapet of the front longitudinal beam (10). So that the earth poured into the space-lattice wall does not fall out of the wall over the parapet top edge of the front longitudinal beam, the cantilever sections (18, 19) contain a retaining wall (56) extending over the length of the precast member and forming, for example, a wedge of an angle section (58) (Fig. 18). <IMAGE>

Patent DE-3600708-A1 (DE)
Title: Antiroll device
Inventor: LUBS WOLFGANG
IPC: B60T8/32
Filed: 1986-01-13
Abstract: The antiroll device is an assembly which, connected to a trailer, is intended to prevent a dangerous building up of oscillations (rolling) beyond a certain movement, in which the trailer is automatically braked independently of the tractor vehicle.  The construction and the mode of action are as follows: A sensor measures the movement of the trailer and detects that certain limits are exceeded and that there is a risk of the trailer swerving and possibly overturning. This finding is relayed to a brake device, which then brakes one or more trailer axles either continuously for a brief period or at intervals. Such advance braking of the trailer inevitably straightens the entire vehicle-trailer combination, gently slows it down and makes braking of the tractor vehicle unnecessary in such an emergency situation, which generally results in the trailer suddenly overtaking the tractor vehicle, since the brake pulse from the front generally does not occur precisely at that instant when the trailer and tractor vehicle form a straight line. The antiroll device is an outstanding contribution to the safer driving of caravans, boat trailers and commercial trailers, which do not always get into difficulties only due to driving mistakes on the part of the vehicle driver, but can also be influenced by weather influences, for example wind or the very strong suction effect, particularly in overtaking manoeuvres involving trucks.
Patent DE-3603036-A1 (DE)
Title: Thinning scissors for hairdressers
IPC: B26B13/08
Filed: 1986-01-31
Abstract: In the case of an innovative pair of thinning scissors, tooth-like projections (6) are present on the corners of the toothed cutting blades (3) which corners are to rest against the pivot screw (5). The said projections (6) exhibit a slight chamfer on the side facing the other blade (2) of the scissors up to the level which would otherwise be reached by the cutting edge (7) of the blade. The tooth-like projections merge into the cutting edge at a slight angle, so that hair captured there is guided to the edge which rests tightly against the cutting edge (1) of the other blade. This makes cutting very efficient and there is no pulling or tugging during thinning. <IMAGE>

Title: Roof gutter clamp (terminal) for lightning protection
Inventor: PROEPSTER JOHANN
IPC: H02G13/00
Filed: 1986-02-27
Abstract: A roof gutter clamp is disclosed having an angled element 4, which forms a gutter arm 5 and a wire arm 6, and has a bent element 8 with an arm 10 and a bead bend 9, which are held together by screws, and has a double-conductor compression element 13 which is held on the wire arm 6 by screwing. In this case, it is desired to reduce the outlay for screwing. This is achieved in that the wire arm 6 of the angled element 4 and the arm 10 of the bent element 8 are screwed by the screw connection 15 of the compression element 13 such that they are located against one another, the arm 10 of the bent element overhangs the wire arm 6 to form the bead bend 9, and the bent element 8 forms an elongating projection 11, after the bead bend 9. The wire arm of the angled element, the arm of the bent element and the double-conductor compression element thus form a packet and are held together by means of a common screw connection. <IMAGE>

Title: Apparatus for setting the circuit amplification of a follow-up control circuit
IPC: F15B9/12
Filed: 1986-04-30
Abstract: A follow-up control circuit which is provided for the motion control of a hydraulic feed drive unit and works with an electrically controlled preset desired-position value and a mechanical actual-position feedback, where the working-medium flows delivered to the drive unit and flowing off from the drive unit are directed via valve elements of a follow-up control valve. The magnitude of the working-medium flows determines the velocity v of the tool movements. The valve elements can be opened together in a controlled manner by adjusting displacements  epsilon 1 and  epsilon 2 respectively in accordance with the preset desired value. The circuit amplification Kv can be reversed by valve-controlled actuation of a reversing device. In this follow-up control circuit, the follow-up control valve has at least one additional valve element which also performs the adjusting movements of the valve elements utilized for the motion control with the circuit amplification Kv1. Leading via this valve element is a flow path which is parallel to the flow path of the follow-up control valve and can be cleared by the activation of an amplifying control-valve arrangement, as a result of which the circuit amplification Kv2 is set, and a control device is provided with which the control-valve arrangement, in keeping with the demand, can be shifted in a controlled manner into its through-flow position effecting the operation with the changed value Kv2.
