Patent DE-2034218-A1 (DE)
Title: Metal elastomer lamineates - with good resistance to flames and heat
IPC: B32B27/00
Filed: 1970-07-10
Abstract: Laminates are produced from thin layers (I) of elastomer material and thin layers (II) of heaat conducting material, e.g. metal, by extending the periphery of layers (II) over the periphery of layers (I) at a distance from each other, in order to form a number of air splits around the periphery of the laminate, and maintaining the layers (I) sufficiently thin that the depth of the space between adjacent layers (II) outside the periphery of layers (I) is so dimensioned relative to the height of the intermediate space that combustion in this space uses more oxidising agent from the surrounding atmosphere than is introduced into this space from the atmosphere, the combustion thus being extinguished at the periphery by a failure of oxidising agent.

IPC: C08F10/02
Filed: 1971-10-16
Abstract: The tubular reactor has at least one reaction zone with an internal diameter of 1.27-7.62 cm., the reaction taking place at 149 degrees - 343.3 degrees C., under 1,000-3, 500 atm. pressure in the presence of a free radical initiator, the overall flow in each tubular reactor zone being sufficient to give a flow index of >=30.65 dm2./s.

Title: Deep frozen poultry prodn - prevents damage to tissue due to the presence of water
Inventor: ROSENFELD GERT
IPC: A23L13/70
Filed: 1971-12-23
Abstract: The tissue damage and resultant loss of natural juices and flavour in deep frozen poultry due to the presence of water in the tissues during freezing can be mostly overcome by the use of injections of 3-8 body wt.% of a 10-40% aq. solution of sorbitol contg. =25% polyalcohols such as mannitol xylol etc. or =25% of sugars such as glucose, dextrose etc. Salt and other flavourings are usually incorporated into the injection fluid which is injected into the breast, thighs, wings etc. of freshly slaughtered, cooled, cleaned, plucked and gutted poultry. All kinds of poultry e.g. ducks, geese, chickens etc. may be treated in this way. Judicious use of flavourings etc. produces a cooked product as good as fresh poultry.

Title: Lightweight conduit for air conditioning etc. - has longitudinal trapezoidal section grooves and formed from thin sheet
Inventor: RYCK JOSEF DE
IPC: F16L9/04
Filed: 1973-08-24
Abstract: The material, preferably between 0.4 and 1.2mm, but up to 2.0mm in thickness, is bent to contain longitudinal reinforcing folds of trapezoidal or similar form.

Title: Small motor with bearings bracket engaged in housing - has bayonet locks to ensure axial rigidity on starting
Inventor: ESTHER HERMANN
IPC: H02K5/15
Filed: 1974-02-06
Abstract: The small motor has a circular housing and a bracket to hold the motor bearings.

Title: Artificial stone or lightweight concrete blocks masonry construction - with block rows top-mortared, transported and laid in half-offset layers
Inventor: MAIER ALFRED DIPL ING
IPC: E04G21/22
Filed: 1974-02-21
Abstract: Blocks are placed in straight rows on a base support, and coated with a strip of mortar on their upper sides. Rows of blocks are gripped by a clamping grab which transports to the masonry under construction. There they are successively piled to form a wall of the requisite height, each row being offset relative to the next row by a half block length or breadth. In forming rows, the blocks may be inserted onto a rail with lateral guiding battens. The strip of mortar may be applied by means of a mortar carrier or slide. The erection of masonry assembled from light concrete brick blocks is made more economically viable by simplifying and speeding the laying process.

Title: Multiple key adjustable lock - has number of cylinders with radial holes for pins and can be opened only by key used on closing
Inventor: FRANKE HELMUT DR
IPC: E05B27/00
Filed: 1974-05-03
Abstract: The lock is designed so that in the open position it can be locked by a given key in a range of keys and the lock can be opened only with the key used on closing. The lock is actuated by a key against a spring force and after completion of locking the key is rotated to the initial position and the key can be withdrawn. The core holes second hollow cylinder holes and the housing holes are aligned with each other. The key is inserted in this position and withdrawn and suitable key is used for rotating the coupled core and hollow cylinder together. This rotation pushes back the locking catch by means of the locking lug on the hollow cylinder. The insertion of the key, for which the lock is adjusted, raises the hollow cylinder pins so that this cylinder can be rotated in the cylinder housing.
Patent DE-2440302-A1 (DE)
Title: Flexible coupling using elastomer material - elastomer centre with varying modulus of shear, between metal rings
Inventor: NAKANO HIDEAKI
IPC: F16D3/76
Filed: 1974-08-22
Abstract: A flexible coupling to withstand variations in torque and tension stresses, without impairing the efficiency of the shaft transmission, has an inner metal ring with a concave periphery, an outer metal ring with convex inner surface and an intermediate ring made from elastomer material with concave surfaces that mate with the metal rings. To reduce the initial stress, the modulus of shear of the outer region of the intermediate ring is less than that of the inner region of the ring. The side surfaces of the intermediate ring are also concave. The convex curvature of the metal rings gradually increases in the longitudinal direction so that the modulus of shear of the intermediate ring is effectively continuously altered. The intermediate ring can be made from several sections with at least two metal spaces and elastomer connecting blocks.
