Patent DE-3128235-A1 (DE)
Inventor: FARR KLAUS
IPC: G07F1/04
Filed: 1981-07-14
Abstract: 1. Security device of an automatic vending machine which for the prevention of the fraud by application of the so-called thread trick displays a coin path (2), which is curved in its entry region, with a thread sensor (1) consisting of a bracket (3), which is provided with small mass, is rotatable about its bearing, is checked for its position by a light barrier and which protrudes into the bent coin path (2) in such a manner that a thread stretched between the entry (5) and exit (6) of the bent coin path is kinked at the bracket (3) and thereby turns the bracket (3) out of its rest setting which has the consequence of a light barrier output signal which thereupon effects the performance of given security measures, characterised thereby, that the bracket (3) is so shaped that a lateral by-passing by the thread is impossible, that an edge (12) protruding into the coin path (2) is formed and that the thread of the coin disposed in the coin path (2) is so guided on the pulling-back of the coin that a certain wedging of the coin behind this edge is assured, that a one-way coin barrier (11) preventing the pulling-back of the coin is arranged behind the coin exit (6) of the coin path (2), that a coin sensor generating a coin test termination signal for prevention of the multiple valuation of a coin hanging at a thread is mounted directly behind the one-way coin barrier (11) and that precautions are taken, which have the effect that a cashing flap (7) assumes or maintains its setting, in which the coins are guided into the final coin till (9), on the occurrence of a light barrier output signal before, during and/or after the cashing operation and remains in this setting until the light barrier output signal has finally again disappeared.

Title: Device for generating a usable drive energy from the kinetic energy of the wind
Inventor: BRAUN JOHANN
IPC: F03D5/06
Filed: 1981-07-30
Abstract: The special feature of the device according to the invention lies in the fact that a sail is held, so that it is capable of oscillating, between two clamping points in a direction at least approximately parallel to the direction of the wind and that at least one transmission element, which converts the oscillation movements of the sail into a reciprocating translatory drive movement, acts on the sail. It has emerged that a sail suspended in this way is set in oscillation even in a very slight wind, the frequency of the oscillations being in the order of a few 1000 Hertz. These oscillation movements of the sail are converted, for example by way of a drive rod and a drive wheel provided with an eccentric journal, into a rotary movement, which can be used to drive a generator. <IMAGE>

Title: Material feed and chucking attachment for multi-spindle bar automatics
Inventor: QUANDT JOACHIM DIPL ING
IPC: B23B13/04
Filed: 1981-09-04
Abstract: The invention relates to a material feed and chucking attachment for multi-spindle bar automatics with horizontal, indexable spindle drum. The aim of the invention is to minimise the machining times per piece by reducing the machine auxiliary times, the object being to design the attachment in such a way that the opening and closing of the chucking of the bar stock is effected before and after the indexing of the spindle drum, the relative movement between material and feed collet is reduced and accurate advance of the material towards the material stop is effected, the advance of the material being effected during the indexing of the spindle drum. The solution according to the invention provides for a roller carrier engaging in grooves of adjacent chucking sleeves and having a mutually staggered opening and chucking roller, the groove width being greater than the chucking and opening stroke of the chucking slide. The opening and chucking rollers open and close the chucking sleeves before, during and after the indexing of the spindle drum by their staggered position at different times in various spindle positions. The invention can be used in the machine-tool building, in particular on multi-spindle automatics, and in its basic features is best depicted by Fig. 1. <IMAGE>

Patent DE-3248085-A1 (DE)
Title: Method and device for balancing rotating systems during operation
Inventor: WEHRFRITZ HEINZ DIPL ING
IPC: G01M1/36
Filed: 1982-12-24
Abstract: According to the invention, during the rotation of a rotating system a ring is formed from a magnetic fluid and rotates concentrically with the axis of rotation. The ring is surrounded by an electromagnet whose magnetic field varies the apparent density of the magnetic fluid in order to compensate the oscillations measured during the rotation. By converting the oscillations, measured during rotation, of the rotating system into control signals for the magnetic field and using the influence, resulting therefrom, of the apparent density or mass distribution of the magnetic fluid ring, it is therefore possible according to the invention to exclude the undesired oscillations during rotation.

Title: Device for adjusting a member
Inventor: BAUER PETER JOSEF
IPC: F16H25/24
Filed: 1983-07-02
Abstract: A device is proposed which serves for adjusting a member which is operatively connected to a positionally adjustable construction element, for example the rear-view mirror of a motor vehicle. The adjusting device comprises a component which is driven in a manner so as to be reversible in its direction of rotation and whose axis of rotation is surrounded by a thread. Cooperating with the thread is a counter piece which is coupled to the member to be adjusted. The counter piece cooperating with the thread consists of an elastic material and is pressed against one portion of the thread in order to avoid damage to the adjusting device when the positionally adjustable construction element has reached an adjustment end position, for example. In this manner, a sliding clutch operating without noise is achieved which also allows infinitely variable manual adjustability of the construction element if the drive for the driven component malfunctions. <IMAGE>
