Title: Calendering polypropylene film or sheet without sticking - by controlling melt index increase during process, esp. by using heat stabiliser
Inventor: HAGN HERMANN ING GRAD
IPC: C08J5/18
Filed: 1980-09-01
Abstract: Prodn. of polypropylene film or sheet by calendering at above the crystalline m.pt. and at a leading-on ratio of each following roll of at least 1.1:1 can be carried out by using a polypropylene starting material of melt index (MI) 0.4-2.0 g/10 mins. (230 deg.C/21.6N) and ensuring during the calendering that the MI does not exceed 2.4 g/10 mins. (230 deg.C/21.6N). The polypropylene opt. contains an inert filler and/or pigment and opt. up to 25 wt.% of polyethylene. Control of the MI is pref. achieved by using a heat stabiliser in such an amt. that the MI increase does not exceed 20% during calendering, the stabiliser being of the type showing a max. vapour loss of 5 wt.% on heating to 250 deg.C at 6 deg.C/min. in an N atmos. An esp. prefd. stabiliser is one which has a vapour loss of 5% at a temp. above 270 deg.C. The polymer does not stick to the rolls and transparent or opaque film or sheet can be obtd. By using calendering temps. of ca. 210 deg.C rolls normally used for processing PVC can be used. Polypropylenes of high MI (e.g. 25-35 g/10 mins.) can be used so long as they are mixed with lower MI polypropylene to give a compsn. of the above specified MI range.

Title: Weaving loom with complete slide fastener - has mandrel guide caliper operated by eccentric mounted on mainshaft
IPC: A44B19/54
Filed: 1980-11-06
Abstract: A needle-loom for weaving simultaneously a pair of slide fastener stringers in coupled form incorporates a mandrel around which monofilaments are wound to form the rows of coupling elements. The mandrel is mounted in a holder which moves vertically in guide slots in two warp yarn spreader plates, between the upper and lower arms of a vertically-reciprocating caliper which permits the monofilament loops to be passed around the mandrel. The caliper is driven by an eccentric which is loosely mounted on the mainshaft, or on a shaft parallel to it and is driven from the mainshaft via a reduction gearing whose reduction ratio is determined by the number of picks which are inserted between each coil of the monofilaments. This construction provides accurate control of the caliper movement at high operating speeds, enabling the loom to be run at speeds in excess of 1500 rpm.

Title: Electricity and thermal meter linearising correction circuit - has analogue-to-frequency converter and nulls and differentiates pulse rate
IPC: G01D3/032
Filed: 1980-12-19
Abstract: A correction circuit for electricity and heat meters with electronic measurement arrangements is for linearisation of arrangements performing multiplication (3) or differencing, conversion of analogue to pulsed digital signals and counting. It enhances the measurement reliability by avoiding the effects of offset and drift. During a monitoring mode one or more input values or derived signals are manually or automatically nulled and the analogue to frequency converter (7) pulse rate stored. During the subsequent measurement phase the measurement pulse rate is nulled. The measurement path output (fm-fo) is the difference of the measurement (fm) and nulled (fo) pulse rates. Alternatively, two parallel identical measurement paths are used. One is operated in monitor mode and the other in measurement mode.

Patent DE-3215748-A1 (DE)
Title: Method and device for operating an ultrasonic dental treatment device
Inventor: HOYER GERHARD ING GRAD
IPC: B06B1/02
Filed: 1982-04-28
Abstract: The method according to the invention is aimed at interrogating the natural mechanical frequency of the electromechanical transducer of an ultrasonic dental treatment device and to store it in the control circuit for the electrical excitation of this transducer. For this purpose, a voltage-controlled oscillator driving the transducer is cyclically driven by a variable scanning voltage (for example sawtooth voltage). When the natural mechanical frequency of the transducer is reached, the amplitude of the scanning voltage is registered at the level existing at that instant. It is done by means of a self-latching trigger stage which, in turn, is driven by a resonance signal and outputs a scanning stop signal to a scanning stage driving the oscillator. To obtain the resonance signal, the voltage drop across a sensing resistor is used through which the current through the transducer or a current proportional to this current flows. A pulse signal occurring under no-load resonance condition of the transducer, which is obtained from the peak in the envelope curve of the voltage picked up across the sensing resistor, is used as resonance signal.
