Title: Tool head for hollowing-out of bores
Inventor: KOCH BENNO
IPC: B23B29/034
Filed: 1981-06-02
Abstract: The invention relates to a tool head for hollowing-out of bores, consisting of a connecting body, two disposable insert supports which can be fixed to clamping means, and adjustment screws for the displacement of the disposable insert supports. The invention is intended to provide improvements in respect of the displacement of the disposable insert supports through the adjustment screws, and the chip division taking into consideration the area of hollowing-out. As regards the arrangement of the adjustment screws, the slide bores (1d) are designed as blind holes arranged at 180 DEG  symmetrically with respect to one another, which blind holes continue in eccentrically offset threaded bores (1e) for the adjustment screws. Accordingly, longer adjustment screws can be used. In order to obtain a chip division, the disposable inserts differ in their position and the outer corner points are arranged offset relative to one another. In the starting position, i.e. with the disposable insert supports pushed together, there is an axial offset Z and a radial offset X-Y. As a result of this the desired chip division and the resulting favourable chip clearance can be achieved over the entire hollowing-out area.
Patent DE-3122849-A1 (DE)
Title: Apparatus for transferring parts from a first to a second conveying track
Inventor: PINTER RICHARD
IPC: B65G15/02
Filed: 1981-06-09
Abstract: An apparatus for transferring parts, such as workpieces and workpiece carriers, from a first to a second conveying track is proposed, which has a curved deflection track whose transport elements, which are in the form of endless belts, carry the parts to be transferred, move them in the conveying direction and swing them about an axis perpendicular to the plane of the deflection path, said belts being tensioned over guide rollers on the outer and inner edge of the deflection track. This results in a simple construction of the apparatus in which the parts can also be transferred in a positionally accurate manner in accumulation mode and in which the transport elements can be easily exchanged. Furthermore, the invention is distinguished in that the deflection is possible with a smaller radius than in the case of the known apparatuses which use curve-negotiating belts or conical transport rollers as transport elements. <IMAGE>

Title: Digital circuit arrangement for filling-level monitoring and wire-break checking on stranding reels
Inventor: KURZ RALF DR ING
IPC: B65H63/02
Filed: 1981-10-29
Abstract: The invention relates to a digital circuit arrangement for filling-level monitoring and wire-break checking on stranding reels, especially on stranding machines, during the stranding process, with the use of electronic components and mechanical or electromechanical measuring and control elements. The aim of the invention is to reduce the outlay for the individual information-processing systems. The object of the invention is to design a digital circuit arrangement for filling-level monitoring and wire-break checking. The object is achieved in that, in cage stranding machines, the angular speed of the running-off reels and, on stranding machines without backturning and having coaxially arranged reels, additionally the cage speed are detected contactlessly by means of binary transmitters and the speed pulses are summed for the duration of a measurement period either in counters arranged according to the number of reels or serially by multiplex scanning in a single counter. A digital computing circuit calculates from this, taking into account the wire diameter, the flange diameter and the degree of filling of the reels.

Patent DE-3203632-A1 (DE)
Title: Laundry spin-dryer equipped with a safety switching device
IPC: D06F49/00
Filed: 1982-02-03
Abstract: A laundry spin-dryer having a safety switching device, which prevents the lid from being opened before the spinning drum comes to a standstill and which receives an indication of the standstill of the spinning drum by means of a tab connected to the motor housing, is to be constructed with few, reliably working parts, in such a way that said safety switching device is activated both in response to a mechanical switching operation and in response to an interruption of the motor circuit and reliably blocks the lid until a complete standstill is reached. For this purpose, there is located at the free end of the lid a catch hook which is equipped on both sides with downwardly directed noses and which is guided between fork-like levers when the lid is being closed. The pivotings caused by the noses are transmitted to a switching lever which actuates the mains switch of the motor and which, manually and/or as a result of the deflection of the tab beyond the switch-on position of the said switching lever, this deflection occurring during the braking of the drive motor designed as a braking motor, and when standstill is reached, is returned into its initial position as a result of the return movement of the tab.

Title: Safety system for hydraulic installations
Inventor: BINDER JUERGEN
IPC: F16K17/20
Filed: 1982-02-03
Abstract: The invention relates to a safety valve for the pressure lines and pressure hoses of hydraulic or pneumatic systems. In these, a pressure drop on one side should be accompanied by immediate, irreversible closure of the safety valve. This is achieved according to the invention by means of a safety valve operating in both directions which has a valve seat (3 and 4 respectively) on the inlet and the outlet side of the through hole (2) in the valve casing (1) and, between these, a rotation space (5) for a rotor (10), the rotor (10) being mounted on a displaceable shaft (19) extending along the longitudinal axis of the valve casing (1) and the shaft (19) carrying at each of its two ends spherical valve members (8, 9 respectively) assigned to the valve seats (3, 4). When a pressure drop accompanied by a simultaneous generation of a flow of pressure medium occurs, the pressure-side valve member (8, 9) is in each case pressed against its associated valve seat (3 or 4) under the action of the rotor (10). The valve members (8, 9) have additional milled recesses (11, 12) behind which sliding blocks (15 and 16 respectively) engage, when the valve is closed, in order to ensure irreversible closure of the valve. <IMAGE>

Title: Device for moving, in particular mixing and/or drying, a material
IPC: B01F7/02
Filed: 1982-06-15
Abstract: The device comprises a vessel (3) with a conically downward-tapering wall (5), an outlet and bearing part (13) located on the lower vessel end and a screw (15) located in the vessel (3). The screw can be rotated about the vessel axis (7) and about its own axis (17) which is inclined relative to the vessel axis (7). The outlet and bearing part (13) has a bearing support (21) rigidly fixed to the vessel (3) and a central element (45) mounted by a bearing (27) to be rotatable therein about the vessel axis (7), the bearing (27) being located in plan outside the lower edge (5b) of the conical wall (5) and being sealed from the vessel interior. The central element (45) forms a bottom surface (53) which faces the vessel interior and is inclined relative to the vessel axis (7) and at the lowest point of which an outlet orifice (47) is present which can be shut off by means of a pivotable shut-off element (49). A peg-shaped screw guide (77), holding the lower end of the screw (15) secure against rotation, is mounted in a bush (39) of the central element (45) by means of bearings (79, 81) to be rotatable about the screw axis (17), these bearings (79, 81) being located underneath the said bottom surface (53) and being sealed against the vessel interior. All the bearings (27, 79, 81) mentioned here are designed as ball bearings, roller bearings or rolling bearings. As a result of this design of the outlet and bearing part (13), heating of the material present in the vessel (3) by bearing friction and contamination of the material by lubricant originating from the bearings (29, 79, 81) can be virtually avoided and good ease of emptying the vessel (3) can be obtained. <IMAGE>
