Patent DE-2805942-A1 (DE)
Title: Homogeniser esp. for mayonnaise creams and emulsions - has different operating cycles according to viscosity of mixture
Inventor: BERENTS ALWIN
IPC: B01F7/00
Filed: 1978-02-13
Abstract: A homogeniser mixer for producing flowable products, esp. mayonnaise, emulsions, creams and the like, where the viscosity is changed during the prodn. process, consists of a mixing vessel with a connected but external revolving homogeniser at the bottom of the vessel. The discharge from this homogeniser passes through a three-way valve to a final discharge and also to a recycling line leading back to the top of the mixing vessel. The outlet from the homogeniser is also connected to the interior of the mixing vessel via a narrow throttling gap or gaps, esp. an annular gap. The total cross-section of the throttle is small compared to that of the homogeniser outlet. Pref. there is a shut-off valve between the homogeniser outlet and the three-way valve. In the initial mixing phase, when the liquid is very thin, the shut-off valve can be closed and the revolving homogeniser extracts liquid through its inlet from the bottom of the vessel and passes it back through the narrow throttling gap into the vessel, regardless of the level of liquid in the vessel. When the liquid is more viscous, it is still initially forced through the annular gap until this becomes impossible, whereupon a sensor opens the shut-off valve and allows the material to be recycled. Finally, the contents can be discharged via the 2-way valve.

Title: REciprocating compressed air engine - has twisted steel bands to transform reciprocating into rotary motion
Inventor: KITZBERGER PAVEL DIPL ING
IPC: F03G1/00
Filed: 1979-11-08
Abstract: The engine has pistons (R) reciprocating in cylinders (B). The pistons are moved by compressed air admitted through valves (C) which are operated by switches at the ends of the piston stroke. Each piston has a holder disc (K) attached to it. Steel bands (J) run from the holder disc to a wheel (Z). In one direction of the piston movement these bands become twisted and in the other direction their spring force unwinds them.

Title: Multi-stage wind wheel for driving generator - has cylindrical metal ring surrounding primary sails enabling sails to be mounted on additional outer circumference
Inventor: WITTKAMPF IGNATZ
IPC: F03D7/02
Filed: 1979-12-24
Abstract: The wind wheel has a horizontal axis of rotation and a central primary rotor suitable for driving an electric generator satisfying private needs of, e.g. farmers and hotel keepers. The sails can be mounted or demounted according to requirements, prevailing wind, season etc. The primary rotor is concentrically surrounded by a cylindrical metal ring. The latter retains the outer ends of the primary rotor's sails. Shorter but wider sails can be mounted on this ring and be terminated by a further ring. This principle can be extended by another stage, the sails on the third ring having their outer edges free. The primary stage on its own is sufficient for low power requirements.
Patent DE-3009217-A1 (DE)
Title: Bag is filled via sealable tube - has inner tube end secured to bag to permit sealing by twisting outer end of tube after filling
Inventor: HERRMANN DIETER
IPC: B65B1/18
Filed: 1980-03-11
Abstract: The bag comprises a closable tubular valve for inserting a filler tube. The valve tube is connected to the bag at a distance from its outer end which connection presents a greater resistance to torsion than does the tube itself when this is twisted to seal the valve after the bag is filled. The valve tube may be double-walled, the inner wall being joined to the outer wall at the inner end of the tube, i.e. away from the outer filling end, while the outer tube is joined (11) to the bag. This permits the inner tube to be twisted about its axis to effect closure.

The second vessel forms a combustion chamber and has an ash drawer or compartment. The toilet is made weather proof by enclosing in an enclosure supplied with compressed air. All electrical components (9) and the combustion chamber (6) are located inside this closed enclosure during combustion. The compressed air is supplied to and removed from the enclosure by appropriate lines. The enclosure may be a cabin. The electric current supplied to the combustion chamber is discontinued if the supply of compressed air fails.

Title: Tennis racquet with double frame construction - is designed to counteract deformation forces during striking of ball
Inventor: FROBEL BJOERN
IPC: A63B49/038
Filed: 1980-06-25
Abstract: The tennis racquet is equipped with devices to counteract the deformation of the racquet frame caused by striking the ball. The device to counteract the deformation force exerted on the racquet consists of a double frame construction of the racquet made up from an outer racquet frame section and an inner racquet frame section which is strung. The inner frame may be fastened to the outer frame at the end remote from the handle, so that when the ball is struck the inner frame bends in the opposite direction to the outer frame. Flexibly values may be chosen so that there is no net change in angle of the inner frame when hitting the ball.
Patent DE-3028714-A1 (DE)
Title: Retiming circuit for high speed data transmission - in which pulse edges are separated and recombined by flip=flop action to maintain transmission in giga-bit-per-second range
Inventor: ENNING BERNHARD DIPL ING
IPC: H04L25/24
Filed: 1980-07-25
Abstract: The object of the circuit is to provide a retiming system for data transmission in the GBit/sec range for non-return to zero (NRZ) signals. At lower frequencies, a D-type flip-flop is used for this purpose, but due to feedback delays this is limited to operation at about 600MHz. The circuit is in fact a reset-set flip-flop which has the attributes of a D-type flip-flop. The NRZ signal is sampled at its bit rate in a three transistor circuit (T1,T2,T3). The signal is applied to one base (1), the bit rate pulse to another (2) and a reference voltage to the third (T2). The result is a series of return to zero (RZ) pulses of one polarity which are then also inverted in a pnp-transistor cascade (T4,T5). Both polarities arrive at a summing junction (S) via time delays (t1,t2) and damping elements (D1,D2). The summed bipolar signal is applied to a Schmitt trigger circuit (T6,T7) acting as a differential amplifier with feedback, at whose output (3) the NRZ signal is replicated in cleaned up form. The feedback delay can be adjusted by a capacitor (C1). The choice of transistor type assists in preventing internal oscillations, and the almost complete absence of internal feedback loops allows operation at the required frequency.
Patent DE-3035504-A1 (DE)
Title: Identical moulds for mass prodn. of pref. polyurethane mouldings - esp. with replaceable inlays produced from master negatives
Inventor: GERMAR HANS ING GRAD
IPC: B29C33/38
Filed: 1980-09-19
Abstract: A negative mould (not shown) is first made mechanically or manually for each of the half-moulds (1,2): from these negative moulds the actual final half-mould (1,2) are then made, pref. by casting. In a preferred variant, where the female half-mould (2) will contain a replaceable silicone inlay (3), this inlay is itself cast using the negative half-mould (2) and the original pattern (4) for the final moulding. From this silicone inlay a positive or male half-mould (similar to the half-mould (1)) having the correct surface structure defined by the original pattern (4) is then made; this can then be used for the production of any required number of silicone inlays in the same female half-mould. Useful for the rapid mass production of very large numbers of mouldings, e.g. arm rests for aircraft passenger seats. The arrangement enables the moulds to be produced in absolutely identical manner and, furthermore, replaceable silicone inlays for forming the external contour of the mouldings to be also produced having identical grain structures and the like.
