Patent DE-3212847-A1 (DE)
Title: Stepladder
Inventor: KUEMMERLIN WALTER
IPC: E06C1/387
Filed: 1982-04-06
Abstract: In a stepladder with only two plate-shaped steps, which are articulated on the uprights of one leg as well as on two links, the steps produce a depth and a step height which lie in the ranges which are usual in steps of staircases. Moreover, in the completely collapsed condition of the ladder, the steps lie in a downwardly pivoted position between the uprights. Two pins projecting outwards from one and, respectively, the other link, which, forming in each case a slot/pin guide, are guided displaceably in the longitudinal direction of the upright in guide grooves of one and, respectively, the other upright of the second leg, are each assigned a locking device (20) which, with the legs (1, 2) fully spread, secures them positively against displacement in their guide groove (17). The height of the completely collapsed ladder amounts to less than 55 cm with a step height of at least 20 cm, and the width of the ladder amounts to 55 cm at most. <IMAGE>

Title: Adaptor for busbars
Inventor: HALEMEIER ECKHARD DIPL ING
IPC: H01R25/14
Filed: 1982-04-22
Abstract: In an adaptor, a control cylinder is supported vertically with respect to the longitudinal axis of the associated busbar. The control cylinder has a thread which interacts with a corresponding thread in the housing of the adaptor. During rotation, the switching cam not only assumes different pivoting positions but also assumes different positions in the rotation axis direction, because of the thread. In consequence, it is possible to carry out the phase selection just by rotating the phase selection wheel.

Title: Control circuit for a rotational speed measuring instrument
Inventor: NITSCHKE WERNER
IPC: G01P3/481
Filed: 1982-07-10
Abstract: A control device for a rotational speed measuring instrument (14) is proposed which converts input pulses synchronous with the rotational speed into signals of constant temporal width and feeds them to said rotational speed measuring instrument (14). This is performed by feeding said signals to the control input of a transistor (11) whose switching junction connects a stabilised voltage source (10) to the rotational speed measuring instrument (14) via an adjustable resistor (12, 15). The second terminal is connected to earth. A resistor (16) is connected in parallel to the rotational speed measuring instrument (14). It is possible in this way both for digital and for analog rotational speed measuring instruments (14) to be used without changing the circuit. Since one terminal is connected to earth, only a single lead is required via the cable to the rotational speed measuring instrument (14). <IMAGE>

Title: Method and device for controlling the speed of a diesel engine in a hydraulic excavator or the like
Inventor: SCHROEDER KLAUS ING GRAD
IPC: F02D31/00
Filed: 1982-11-26
Abstract: The speed of a diesel engine of a hydraulic excavator is controlled in such a way that prior to or on the assumption of load operation the control lever of the speed governor of the injection pump is moved into the preselected load position and into its idling position on conclusion or in the event of an interruption in load operation. In order, by simple means, to achieve control of the speed as a function of the particular load of the diesel engine, the control rod displacement following cessation of the main load is measured and the control lever is set to idling position when the control rod in its travel into its speed regulation position corresponding to the higher idling speed has reached a switch-over position which lies above the idling position of the control rod with the control lever located in the idling position. When the control rod passes through the switch-over position due to the reduction in speed when resuming load operation, the control lever is moved back to the preselected load position. The control lever can also switch over whenever an increase in speed occurs following cessation of the main load and when a reduction of the lower idling speed occurs on resumption of load operation.

Title: Fishing hook
Inventor: HAMBARSOMIAN EDWARD
IPC: A01K83/02
Filed: 1983-03-01
Abstract: In fishing hooks with a shaft which is bent in a U-shaped manner and tapers into a point and with, arranged on the shaft under the point, a barb, it has emerged that, in spite of the barb, a freeing of the fishing hook from the jaw of a hooked fish, in particular a fish of prey, can occur if the fishing line leading to the fishing hook is loosened after the bite. In order to make possible secure holding of the fishing hook in the jaw of a hooked fish, there is arranged, according to the invention, foldably movably on the shaft 6 under the barb 2 a locking member 3 with, arranged on the end remote from the barb, a laterally projecting actuating nose 8, which member is movable out of a rest position parallel to the shaft 6 into a locking position transverse to the shaft 6. By means of the locking member projecting transversely from the shaft part bearing the barb, an anchor which takes hold in the jaw of the fish and which can reliably not free itself from the jaw of the fish is formed (Fig. 1). <IMAGE>

Patent DE-3315938-A1 (DE)
Title: Clutch
Inventor: WEBER KARL-HEINZ
IPC: B25B23/14
Filed: 1983-05-02
Abstract: The invention relates to a clutch for a screwdriving tool, having two clutch parts, which can be disengaged when a predetermined torque value is reached, can be moved away from one another against spring force and enclose between them driving balls supported on cam surfaces of both clutch parts, and a cage body in which the driving balls are rotatably held in pockets open to the clutch parts. In known clutches, the cam surfaces and the edges of the pockets in the cage body become worn out during prolonged use, because the driving balls emerge slightly from the pockets upon disengaging the clutch and perform a displacement movement, so that uncontrollable relative movements of the driving balls result, which are subsequently corrected again by sudden movements. According to the invention, this is avoided by the width of each pocket opening facing a clutch part being smaller than the outside diameter of the driving ball.

Title: Dynamically high-quality supporting magnets, and combinations of supporting-propulsion systems
Inventor: WEH HERBERT PROF DR ING
IPC: B60L13/10
Filed: 1984-04-06
Abstract: In order to achieve good dynamic adjusting characteristics in the case of electrical supporting magnets, the stationary component of the supporting force is generated by a coil whose current is taken from a voltage source (battery) which is not adjustable (from the dynamic viewpoint). The adjustable flux component is generated by a control coil having a relatively small number of turns and a separate voltage source (control voltage). In order to limit interactions between the control circuit and the basic load circuit, current stabilisation is used in the latter, the major components not being mechanically connected to the magnet which is to be controlled. The adjusting characteristic of the magnet is determined by means of the relatively small inductance of the control circuit (Figure 1a). A series circuit consisting of a plurality of magnets which are regulated individually is proposed as a possibility for current stabilisation, so that neither additional mass nor additional losses occur. Furthermore, reference is made to an actively controlled stabilisation circuit and a combination of linear drive and support regulation. Using the measures described, a rapid change in the magnetic forces and a system improvement can be achieved with a relatively low adjusting power. <IMAGE>
