Patent DE-2756739-A1 (DE)
Title: Processing animal carcass, bone and meat waste - by enzymatic alkaline or acid hydrolysis opt. after protein denaturation, giving prods. useful in foodstuffs, feedstuffs and fertilisers
Inventor: BERG ALEXANDER DIPL CHEM DR
IPC: A23J3/34
Filed: 1977-12-20
Abstract: Comminuted animal carcase-, bone- and meat waste is enzymatically hydrolysed, opt. after an acid or alkaline protein denaturation at 100 degrees C and cooling to 30-70 (50) degrees C. Hydrolysis takes place at the optimum pH for the enzyme used. Fat and protein hydrolysate are then sepd. from one another, by unmixing, e.g. by centrifuging, at 80-100 degrees C., and the insoluble residue is opt. filtered off. The protein prods. can be used in super-protein diets, or as food additives e.g. in diabetic foods, soup flavours, animal feedstuffs, etc. The difficulty soluble residue obtd. in bone processing can be used as fertiliser or as animal feedstuff additive. Waste prod. treatment is quick, e.g. 3 hrs.; non-polluting and odourless. Water-insoluble protein hydrolysates are obtd. in high yields.

Title: Motor vehicle air spring unit - has tubular tension bolt accommodating guide bar coupled to supporting sleeve
Inventor: MERKLE JOSEF
IPC: B60G15/12
Filed: 1977-11-12
Abstract: The motor vehicle air spring has two spring surfaces of different sizes acting in opposite directions, their area being variable dependent on spring movement and coaxially supported from each other. The chamber is formed by two enclosing roller type bellows whose working surfaces, facing away from each other, are supported on spring pistons of different dias. rigidly secured together. Distortion of their loops with spring movement result in vol. alterations counteracting each other. The spring force is transmitted via the pistons on one hand and a sleeve for the bellows walls on the other. The pistons are secured together by a central tension bolt. This bolt is a tube (307) in which an axial guide bar (343) works, coupled to the support formed by the sleeve.

Title: X=Ray lens formed by internal surface of hollow shell - lined with crystals reflecting by Bragg's law
Inventor: FRITZ KARL DR
IPC: G21K1/06
Filed: 1978-04-11
Abstract: A lens for concentrating X-rays consists of the internal surface of a hollow object lined with crystals, at which the lattice planes reflect the radiation according to Braggs's law. More specifically, the form of the internal surface is such that the major part of the radiation is concentrated into a geometric figure, esp. a point. Pref. radiation issuing from the point is reflected internally according to Bragg's law and is thus focused at another point. With this arrangement, the internal surface is a surface of rotation for which the peripheral angle is (180 degrees-2a), where a is the angle of the Bragg's equation. Used for focusing X-ray images of small areas in accorance with optical laws. The arrangement provides accurate and clear focusing with a wider practicable base angle than was previously possible.

Title: Return lock for long distance skis - prevents back sliding of ski using spring tensioned movable grip controlled by stops
Inventor: LANDERER MEINRAD
IPC: A63C7/00
Filed: 1979-02-08
Abstract: The return lock is for long distance skis. It can be screwed onto skis in the binding section in order to prevent any sliding back during running. Bearing elements and front stops are attached on both sides of the edges. There are gripping elements (3) with a smooth curved edge and prongs to grip the snow. They are positioned so that a slight pendulum movement in every direction up to the front stops is possible.

Title: Fibre lap weight monitoring device - producing proportional control signal to maintain constant lap weight per unit time
Inventor: GUILLOT FRANZ E
IPC: D01G23/04
Filed: 1979-02-14
Abstract: Appts. for continuously monitoring the weight of a fibre lap feeding spinning machinery comprises a series of measuring rollers arranged side-by-side to cover the full width of the feed conveyor, each of which continuously registers the weight of the section of the lap passing over it. An integrated signal from all the rollers, incorporating the speed of the lap, is compared with a pre-determined standard value, any deviation being used to adjust the speed of the conveyor proportionally, to ensure delivery of a constant weight of fibre per unit length, or unit of time. Feed rate is maintained with great accuracy and reproducibility, regardless of the type of fibres, or their volume, and is effective for small batch sizes. All types of variability, whether short or long term, periodic or aperiodic, are minimised.

Inventor: LECHNER ROBERT DIPL ING
IPC: H04Q3/00
Filed: 1979-09-26
Abstract: The circuit arrangement monitors operating conditions of a group of direct current devices. The operating conditions are represented by different potentials occurring at a sampling connector of each direct current device. A first and a second selector unit, each having parallel signal inputs, are arranged symmetrically with respect to commonly connected outputs. Signal inputs of the first selector are connected to corresponding sampling connectors of the DC devices. A control unit for generating a control signal train has an output which is commonly connected to control inputs of both selector units. Commonly grounded filter capacitors are connected to the signal inputs of the second selector unit. A comparator is connected by a first input to a reference voltage source and by a second input to the outputs of both selector units. At the output of the comparator there is delivered a rated output signal evaluating the potential at the presently selected sampling connector with respect to said reference voltage.
