Title: Insulating auxiliary under roof structure - comprises hard foamed overlapping elements spanning intervals between battens
Inventor: RAUE KLAUS ING GRAD
IPC: E04B7/22
Filed: 1975-05-02
Abstract: The roof sheathing serves as an under-roof structure for roofing made of hard materials, in areas with moderate to hard climatic conditions, and at the same time it acts as a support structure and auxiliary roof, serviceable in the event of breakage of the hard roofing, providing protection from damp dust and snow, and a degree of heat insulation, also load bearing access during roofing construction. The scaled overlapping structure is made of hard foamed material or similar and comprises elements which each span the interval between two adjacent roof battens, with some overlap. They are made in one piece, if necessary with a directly joined coating, and are laid directly on top of the upper roof batten, and overlapping on top of the element below on the lower batten. There may be a moisture-resistant coating on the underside.

Title: DC control system for three-phase asynchronous motors - uses thyristor static inverters in pole amplitude phase shift method
Inventor: EICHHOEFER HEINZ DIPL ING
IPC: H02P23/06
Filed: 1975-05-17
Abstract: The asynchronous, three-phase motor drive system uses the pole-amplitude, phase-shift modification principle. Each of the three-phase windings of a star- or delta -connected motor is fed from a static inverter using thyristor switches (11). These are supplied from a dc source and a regulator. A pulse frequency for switching the respective thyristors is derived from a generator, where frequency is controlled by an electromagnetic impulse unit attached to the motor shaft which provides a sum and difference slip frequency. This control signal can be processed in a 6-bit shoft-register to produce the required commutation sequence for the various phase- windings, the poles of which can be switched in different configurations without the use of mechanical devices.

Title: Brake disc for motor cars - is composed of a cup-shaped inner steel portion and a cast iron ring
Inventor: KEINER WERNER DIPL ING
IPC: F16D65/00
Filed: 1975-09-04
Abstract: The brake disc is constructed of a cup-shaped inner portion made of steel, onto which is cast a ring of cast iron comprising >3.5% C, 1.9+0.2% Si, 0.6+0.1% Mn,0.25-0.4% P, and 0.15% S. The cast iron ring is carried on a rim of the steel cup which has a conical shape. The rim of the cup-shaped portion is provided with teeth, and the side wall of the steel cup is provided with holes for cooling. The steel portion gives the necessary strength and the cast iron ring the required braking properties. The cast iron has good damping property due to the higher C content which avoids brake noise, and the Si content gives a pearlitic structure over a usual thickness of 15 mm, and high wear resistance. Braking and damping property is better with this cast iron of 200-210 HB hardness than with a cast iron 230 HB hardness but lowr C and P content. A good bond is obtd. when the iron, cast over the toothed rim of the steel cup, which is placed into the mould, solidifies.

Title: Cylindrical casing rotary piston IC engine - has sliding sealing plates between combustion chambers held in oscillating bearing blocks
Inventor: EICHNER JOHANN
IPC: F01C1/328
Filed: 1976-05-20
Abstract: The engine has a cylindrical casing with a central bore in which an eccentric cylindrical piston revolves. The piston has a central bore with internal gear teeth which mesh with a pinion which is coaxial with the casing. As the piston rotates on its eccentric path, it causes the pinion to revolve. The casing has three cylindrical recesses on its inside which contain oscillating cylindrical bearing blocks. Each of these has a slot in which a sealing plate can slide. The other end of each plate has a spherical head which fits in a bearing recess in the piston. This provides effective sealing between the three combustion chambers which are formed between the piston and the casing.

Title: Regulator for solar energy heating system - uses energy gain in storage for regulating pump motor
Inventor: SCHWARZ KARL
IPC: F24D17/00
Filed: 1976-09-30
Abstract: The regulator is used in solar energy collectors for obtaining useful heat transferred to a heat storage. The heat transfer medium is circulated by a pump in a pipe system. This regulator keeps pump connected while energy is gained by the storage and is disconnected when the storage begins to lose energy. The temp. difference of the solar energy collector in relation to storage temp. is used as regulating magnitude when the heat transfer medium is at rest. When the heat transfer medium circulates then the energy gain of the heat transfer medium between the collector inlet and outlet is used as the regulating magnitude. In positive energy gain of the heat transfer medium between the collector inlet and outlet is used as the regulating magnitude. In positive energy gain case the medium is circulated. In decreasing or negative energy gain case the circulation is stopped.

Title: Leakage indication for centre packing of piston pumps - uses two centre packings for determining liq. plastics of multiple components
Inventor: BEIL HANS WERNER
IPC: G01M3/00
Filed: 1976-10-15
Abstract: Leakage indication for centre packing of piston pumps for determining liquid plastics of multiple components uses two centre packings which are installed at a distance from each other. The outer cylinder is provided with bores. Material escaping between the packings is rendered visible and wear and tear of the packing is thus indicated. Wear and tear of the centre packing is controlled without the necessity of dismounting the pumps. It becomes visible from the outside by means of the bores in the outer cylinder and thus any incorrect determination of the liquid plastics is prevented.

Abstract: A method is given for culturing a bioculture in a broth or culture medium. The optimum culture conditions are maintained by replenishing or changing the culture medium in accordance with the pH. pH control may be effected by passing two different gas mixts. into the culture medium which control the latter's pH. The method is esp. applicable to those cultures whose growth is linked tothe surface of solid objects, e.g. diploid fibroblasts. By maintaining optimum conditions, reproducible results are obtainable. Economies in the use of the nutrient medium are also achieved.
