Title: Separating device
Inventor: REITER JOHANN
IPC: B65G47/14
Filed: 1983-11-07
Abstract: In a separating device for separating small parts with flange and shank parts, the width of the final upper thread of a screw-like baffle constructed in a container with the shape of a circular cylinder is adjusted by an adjustable plate which can be displaced from outside the container in such a way that the plate can now only be passed by small parts arranged one behind the other. Moreover, a slot is formed downstream of the displaceable plate as seen in the conveying direction of the small parts, at the end of the final upper thread of the baffle in a delivery section, and the width of this slot is made adjustable in accordance with the diameter of the shank section of the small parts to be separated by displacing the delivery section on guide pins until the shank section of the small parts to be separated enters the slot and its flange section slides on the edges at both sides of the slot. This separating device can therefore be simply and very rapidly adjusted and/or converted to the dimensions of the small parts to be separated, especially to the diameter of the shank section.

Title: Knock-in tack
Inventor: STRAHL GERHARD
IPC: F16B15/00
Filed: 1983-10-24
Abstract: Conventional, short steel nails cannot be used without risk of injury. This novel knock-in tack can be knocked in without any risk, by means of its retaining wire, and primarily makes it possible to knock the knock-in tack in safely, accurately and reliably in that the user can knock the knock-in tack into the wall using full force, because a large impact surface, a short thick shank and the retaining wire permit safe, accurate and rapid work. The knock-in tack is similar to a drawing pin of a conventional type, is produced entirely from hardened steel or hard alloy, has a truncated, conical peg, and has a retaining wire which is broken off at a weak point once the knock-in tack has been knocked into the wall.

Title: Self-locking safety-belt reeling device
Inventor: BUTENOP KLAUS
IPC: B60R22/405
Filed: 1984-02-02
Abstract: In a self-locking belt-reeling device for safety belts, especially in motor vehicles, with a belt band-sensitive and a vehicle-sensitive blocking of the belt-reeling shaft, a locking member mounted eccentrically to the shaft axis being controlled radially outwards, up to engagement with a toothing fixed to the housing, by a control disc mounted centrically relative to the reeling shaft and coupled to the locking member via a pin/slot connection, and the control disc of high mass inertia for the belt band-sensitive blocking being supported resiliently on the reeling shaft and cooperating with a sensor via an external toothing for the vehicle-sensitive blocking, there is the problem that with belt band-sensitive blocking, because of the uncontrolled deflection of the locking member, it is impossible to prevent a tooth-on-tooth blocking of locking-member teeth and the toothing fixed to the housing, with the result that an incorrect locking putting the occupant's safety at risk can occur. To avoid this, it is proposed, in the belt band-sensitive blocking, that the rotational delay of the control disc (13) of high mass inertia be convertible, by means of formations (20, 21, 23, 24, 31) on the control disc (13) of high mass inertia, into a locking movement of the sensor (30) for the vehicle-sensitive blocking. <IMAGE>

Patent DE-3408845-A1 (DE)
Title: Ignition system for an internal combustion engine with an ignition period which is controlled by the engine speed
Inventor: MEHLICH GUENTER
IPC: F02P3/045
Filed: 1984-03-10
Abstract: Ignition systems of internal combustion engines must ensure that even at a high engine speed the ignition coil is flowed through for a sufficiently long period of time by DC current in order to develop the full ignition power. By means of circuitry, it must be ensured on the other hand that the closing period is not too long in the low engine- speed range. With the ignition system introduced, it is possible to control the closing time, in a manner matched to requirements, as a function of the engine speed of the internal combustion engine by lengthening or shortening the ignition time. This takes place essentially by the use of a programable timer circuit and a field effect transistor. An integrated assembly, NE 555, emits, when driven, square-wave pulses whose length is determined by the time constant of the resistor connected to its points 6 and 7 and of the capacitor. The field effect transistor is connected by its gate to a capacitor which has a charge state determined by the engine speed of the internal combustion engine. Depending on the size of the voltage present at the gate, the drain-source junction of this transistor is more or less conductive to current and thus varies the resistance acting at the points 6 and 7 of the time switch. This in turn results in the output pulses becoming lengthened or shortened from point 3 of the time switch. <IMAGE>

Title: Accelerator travel limitation on the drive foot pedal of motor vehicles
Inventor: KASTNER GUENTER DIPL ING
IPC: B60K26/02
Filed: 1984-06-19
Abstract: The invention relates to motor vehicle engineering. The aim of the invention is a defined travel limitation of the accelerator linkage on the drive foot pedal, in order to save fuel by preventing a high engine speed.  At the same time traffic safety requirements must also be met. The object of the invention is to create a basic circuit for an accelerator travel limitation on motor vehicles, which can be used regardless of the design of the accelerator linkage and comprises only a few components. The essence of the invention lies in the fact that a pneumatic cylinder with piston rod limiting the linkage lever is assigned to the drive foot pedal located on the drive pedal shaft and the pneumatic cylinder is connected to a 3/2-way valve, to which any number of controlling signal emitters are assigned. The sphere of application of the invention is motor vehicles which are equipped with injection or carburettor engine and have accelerator operation. <IMAGE>

Title: Circuit arrangement for telecommunications switching systems, in particular telephone switching systems, with information-processing central and/or decentralised switching mechanisms
Inventor: ERNST WOLFRAM DIPL ING
IPC: H04M3/36
Filed: 1984-09-27
Abstract: The data indicating the capacity of a central processor (CP) are sent by the latter to the group processors (GPs) along with setting and control commands to be transmitted by the CP to the different GPs in conjunction with connection set-up procedures (tie-to-the-leg method). These data cause a reduction in work load through systematic rejection or suppression of a specific percentage of new seizures of connection lines which can be seized in the incoming direction. The connection lines are reverse-blocked on the basis of this percentage, or information indicating the proportion of connection lines which are not to be seized therefrom is transmitted for in each case one trunk group, according to this percentage, to the distant exchange concerned. <IMAGE>

Title: Three-dimensional framework system comprising profiled steel bars
Inventor: BLUM ROLAND
IPC: E04B1/19
Filed: 1984-10-13
Abstract: The subject of the invention is a junction connection for profiled steel bars, with the aid of which three-dimensional frameworks can be designed by the tetrahedron/half octahedron construction method. All commercially available steel profiles can be used as bars for the three-dimensional frameworks, but these are usually round tubes. On both ends of the bars there are attached head pieces which are designed such that up to twelve bars can run into one junction and can be connected by commercially available screws. In the case of the diagonal bars, said head piece comprises a "tongue" (3) which is cut from flat iron, is provided with a bore and is welded to the steel profile. For the flange bars, angle profiles (9) containing 4 bores (11) are additionally welded with the tongues. These bars are then assembled such that they can be directly screwed together without a further junction piece. The force transfer in the junction connection has proved so favourable that considerably greater spans and higher loadings can be achieved in comparison with existing systems. <IMAGE>

Title: Method for contactless determination of the position or the offset of a hole located in a workpiece
Inventor: WEULE HARTMUT PROF DR ING
IPC: G01B11/03
Filed: 1984-10-17
Abstract: The invention relates to a method for contactless determination of the position or the offset of a hole located in a workpiece. It is the object of the invention to find for this purpose an optical/electronic method which utilises the reflection properties of the workpiece surface to enable the position of the hole to be detected and evaluated. This object is achieved according to the invention by projecting a section, which contains the hole (17), of the workpiece surface, to which vertical illumination is applied, on a position-sensitive photodiode (4), doing so in an optical manner, and by using the current distribution, corresponding to the light distribution on the measurement field, in the photodiode as measurement signals defining the position of the hole or the offset of the hole after evaluation in an electronic system for controlling a working device. <IMAGE>
