Patent DE-2427525-A1 (DE)
Title: Static operating element for AC electricity meters - has a multiplier which multiplies input current by input voltage
Inventor: FRIEDL RICHARD DR ING
IPC: G01R21/133
Filed: 1974-06-07
Abstract: The product is applied to an integrator for mean value formation. Reference signals of a frequency different from the mains frequency, and of such value and polarity are in addition applied to the multiplier inputs, that the mean value with respect to time of the reference product practically compensates the measured value. The necessary reference product is controlled by the integrator output in a control loop. A pulse train proportional to the reference product is generated for counting. An analogue signal to frequency convertor follows the integrator. Its output pulses release signals of constant energy content which are applied, possibly through convertor stages such as filters, rectifiers or invertors.

Title: Foundry sand mixing appts - falling curtain of dry mixture blown by air jets and sprayed with liquid
Inventor: OTTERBACH JOACHIM ING GRAD
IPC: B01F5/20
Filed: 1974-06-11
Abstract: A foundry sand mixer has a tubular casing with a funnel shaped opening at the top for premixed sand and additives, and an inverted cone underneath, so that the mixture falls as a circular curtain around the interior periphery, until it reaches a ring of upwardly directed jets of compressed air which transforms the curtain into a whirling mass. Housed under the inverted cone is a liquid spray jet which discharges a fine spray of liquid additive over the whole of the interior, so that an even, thorough wetting of the sand mixt. is ensured. The wetted mixt. then falls vertically downwards, passing a row of air discharge holes around the side as it does so. An adjustable ring is mounted on the top of the inverted cone to control the feed of the dry mixt. around the interior.

Title: Electric or standard toothbrush with curved contours - includes a tip for improved cleaning of spaces between teeth etc.
Inventor: PAETZOLD CHRISTOPH DR MED
IPC: A46B9/04
Filed: 1974-07-15
Abstract: The brush head (2) has an effective working surface formed by at least one curved trough section flanked on one or both sides by an outwardly pointing wedge section (4), the length of the chord or the trough arc corresponding approximately to the average width of the large and small molars. If the brush head is fitted with two such arc troughs then the chord length corresponds to the width of the molars and premolars but in each case the shape of the trough matches the convex outer face of the teeth whilst the wedge angle corresponds to that of the gaps 5 between the teeth. In this way the shorter bristles effectively clean the entire face of the tooth whilst the pointed wedges effectively clean the gaps in between.

Title: Drive motor system for record player - uses motor with external rotor and stator winding with even pole-number
Inventor: BUENTING GERHARD
IPC: H02K17/16
Filed: 1974-09-04
Abstract: The drive motor system, for a record player or tape recorder, uses an induction motor with an external rotor. The motor has 2, 4 or 6 poles to its stator windings, and an air-gap of less than 1 mm. The magnetic return yoke consists of a deep-drawn soft-iron pot. The advantage of this design lies in its using the same amount of material as an internal-rotor motor but, because of its external rotor, there is significantly lower vibration and noise production. It also requires less screening than the internal rotor type, and the motor drives the turntable (1) of a record player directly.

Title: Glycol recovered from polyester prodn - by distilling off-gases without condensation
Inventor: LANGNER SIEGFRIED DIPL ING
IPC: C07C31/20
Filed: 1974-10-28
Abstract: Process for recovering glycols from glycol terephthalates prodn. by distillation of the vapour mixt. coming from the esterification zone comprises subjecting the vapour mixt., without any intermediate condensation, to distillation in vacuo, pref. at 50-400 Torr absolute, and then recycling the high-boiling liquid fraction, principally glycol, so produced to the esterification process while still hot. All or part of the glycol may be returned to the zone where glycol and terephthalic acid make-up are mixed, or part is returned directly to the esterification reactor and none removed, or a part of the liquid is removed from the process. Recovery is effected more efficiently with less consumption of energy; at lower temp. (less glycol ether formation); water (which has to be re-evaporated) is not recycled with the glycol but any esters present are material losses are reduced; and by recycling to the mixing zone the glycol-acid suspension is diluted to made easier to transport.
