Title: Conveying fleece into chipboard or fibre board press - by endless chains with clamping levers to grip edge of fleece
IPC: B65G37/00
Filed: 1980-04-01
Abstract: Appts. for transporting flat or sheet-like elements having parallel longitudinal edges is intended esp. for the transporting of fleece elements or underlays for chipboard, fibreboard and similar production processes into intermittently operating presses. The apparatus consists essentially of two endless conveyor belts, one on either side of the conveying path, with clamps for gripping the edge of the fleece. Each clamp comprises a lever (50), pivotally mounted on an axis (49) perpendicular to the conveying direction, the length of the lever being slightly greater than the distance from this axis to the conveyed fleece (17), so that the lever jams on the surface of the fleece. The end of the lever which comes into contact with the fleece pref. has a replaceable, hard-wearing tip (50). Secure clamping of the fleece is achieved without the need for any holes in which jaws may grip.

IPC: G06F3/16
Filed: 1980-05-07
Abstract: PURPOSE: To provide an inexpensive voice synthesizer for synthesizing human voice from a coded parameter stored in a solid state element or inputted from the external. CONSTITUTION: The voice synthesizer 10 (12A, 12B) is controlled by a programmed microprocessor 19 and uses data coding and compression technique to reduce a data ratio. A coded parameter is used for controlling the reflection characteristic of a digital filter included in the synthesizer 10 and an output from the digital filter is applied to a digital/analog converter. Thereby the digital output from the filter is converted into a sound signal, which is sent to a conventional amplifier 20 and a speaker 5.

Title: Opto-electronic value measurement with ageing and temp. compensation - by comparing reference and measurement beams from common source
Inventor: REISSLAND MARTIN-ULRICH PROF D
IPC: G01D3/028
Filed: 1980-09-08
Abstract: Receiver signals corresp. to a reference light beam are compared with a beam whose intensity varies with the value being measured. Light source brightness fluctuations are also compensated for as are receiver variables tending to reduce accuracy. The light from the source (1) is alternately deflected along measurement (4) and reference (5) beam paths. Both beams are deflected onto a common optoelectronic receiver (10). The receiver output is changed over between the two inputs of a divider (15) in synchronism with the deflection of the light beams. Each divider input is connected to a storage device (16,17). The beam is defected using an electrically controlled mirror (6) switched between reflection and transmission.

Title: Method of cooling a milling tool, in particular at its cutting edges, and milling tool suitable for this method
Inventor: HOCHBERGER ERHART
IPC: B23C5/28
Filed: 1981-02-11
Abstract: To cool the cutting edges of a milling cutter mounted on a milling spindle or the like, a coolant is fed to the milling cutter via bores in the milling spindle or the like, which coolant flows to the cutting edges through bores inside the milling cutter which lead out near the cutting edges. A milling cutter which can be used for this method is provided with approximately radially running bores which start from its centre bore and lead out directly in front of the cutter tooth faces. For prolonged use of the milling cutter, the bores in the new state are partly still covered by the cutter teeth. Further bores can be provided which perform the function of feeding the coolant only after repeated re-grinding of the milling cutter. <IMAGE>
Patent DE-3106377-A1 (DE)
Title: Electromagnetically actuated shut-off valve
Inventor: VILLEVAL DENIS
IPC: B60H1/00
Filed: 1981-02-20
Abstract: Electromagnetically actuated shut-off valve in liquid conduits, the opening and closure of which are performed by means of a diaphragm. This diaphragm, which is clamped at the edge, is closed and held in position centrally by an electromagnetically controlled valve, thereby keeping closed the outlet pipe. The closing pressure is determined by the liquid flowing in next to the outlet pipe, which passes behind the diaphragm through a very small opening and presses it onto the valve seat. When the central valve is released, the pressure-generating liquid flows off and the closing pressure on the diaphragm decreases, its elasticity allows a change in position and the outlet opening is freed. The diaphragm is closed again without a spring and solely by closing the central valve by virtue of the renewed build-up of the pressure of the liquid flowing in through the small opening in the diaphragm.
