Title: Three-coordinate measuring device for space points - has three light beams producing spots on plane coordinate system, from which computer calculates coordinates
Inventor: JANOCHA HARTMUT DR ING
IPC: G01B11/00
Filed: 1977-08-26
Abstract: A plane electrooptical coordinate system is used for the space point coordinates determination. The point of intersection of axes of three light beams, at constant angles to each other, is identical with the point in space to be measured. The space point coordinates are calculated by a directly coupled electronic computer from the position of light spots produced by the three light beams on the plane coordinate system. A first approximate solution for the coordinates can be obtained using a separate measurement process. One of the three light beams is used as a guiding beam in the feed-back path of a control circuit, so that the direction of all three lights beams are so controlled, that their spots always fall on the coordinate system for any position of the space point within the measurement volume. A rotating mirror drive (23) is used for azimuth adjustment.

Title: Combustion engine cooled by compressed air - which is subsequently used to drive expansion engine
Inventor: WIESER RUDOLF DR
IPC: F02G5/04
Filed: 1977-09-24
Abstract: The cylinder (1) of the combustion engine is cooled by compressed (13) air at a pressure of at least 1.5 bar, but preferably at 3 to 15 bar. The heated air is subsequently used to drive an expansion engine (14) such as a turbine, or a reciprocating or rotary piston engine. The main engine may be a reciprocating piston engine, the expansion engine (14) being coupled to the crankshaft (9), e.g. via a transmission (11). The cooling air may flow through the cooling ducts (16) around each cylinder liner (5) and then through each cylinder head (1b).
Patent DE-2748703-A1 (DE)
Inventor: DIDEK STANISLAW DIPL ING
IPC: D01H4/32
Filed: 1977-10-29
Abstract: The apparatus has a homing cylinder (4) and a feed mechanism comprising a feed roller (19) and a clamping member. A fibre sliver is fed to the fibre-opening apparatus, and from the fibre sliver individual fibres are supplied to the spinning rotor and are deposited as a small sliver twisted to form a yarn which is drawn off and wound onto a bobbin. Between the feed roller (19) and the combing cylinder (4) there is a connecting channel (11) which has an end wall (41) confronting the working surface (23) of the feed roller (19), side walls (42a) and a feed wall (43). A guide wall (47) merging into the hollow space (10) of the combing cylinder (4) and adjacent with an edge (48) to the working surface (23) of the feed roller (19) forms the rear part (46), whilst that portion of the working surface (23) of the feed roller (19) limited by the edge (48) and the entrance (44) of the connecting channel (11) forms the front part (45) of the feed wall (43) of the connecting channel (11). The depth (h) of the cross-section of the connecting channel (11) first increases from the entrance (44) and then decreases. In the event of a thread break, this design prevents the fibre sliver from running out of the connecting channel (11), and therefore the subsequent piecing operation can take place without difficulty. <IMAGE>

Title: Speed control of drives connected in cascade - determines each drive speed by frequency derived by division of stabilised frequency and stored
Inventor: SCHAUFUSS ERICH DR
IPC: H02P5/51
Filed: 1977-12-17
Abstract: Nominal value of speeds of individual drives are derived as nominal frequencies by digital division of a stabilised frequency. The digital control circuit is an integral controller. Ratios of frequencies of two consecutive drives are determined during an adjustment phase, and stored. The ratios are always smaller than or equal to one. During a subsequent, multiplication phase, the ratios are maintained constant during normal operation, and altered in case of a disturbance. One drive serves as control drive and the stored ratios are multipled by the frequencies of adjacent drives.

Title: Machine or engine air duct sound insulation - has walling made solely of foamed plastic, pref. polyether or polyurethane
Inventor: ABELS THEODOR ING GRAD
IPC: E04B1/84
Filed: 1978-05-05
Abstract: The insulation is used where noisy machines or engines are housed in an interior where air has to be supplied or carried away, esp. for cooling. The sound-insulating device is for an air duct, with a series of parallel insulating wall sections made of foamed polyether, polyurethane or similar absorbent material, esp. urethanes on a polyester base. The sound-insulating walls are made solely of such material. Their length is pref. at least four times as great as their distance apart. Walling of the air duct itself may be coated with the same material, this coating and the insulating wall sections being formed from a cohesive block. This provides optimal insulation for sounds in every frequency range and prevents noise reflections.

Title: Controlled nuclear fusion with magnetic compression of plasma - using excitation windings concentric with axis of annular reaction vessel
Inventor: WIDMANN DIETER
IPC: H05H1/10
Filed: 1978-06-22
Abstract: Appts. for obtaining a controlled nuclear fusion reaction with a positive energy balance operates by magnetic containment and compression of a plasma. Annular reaction vessel has an excitation winding in which the turns run parallel to the vessel wall and concentrically around the principal axis of the vessel; the turns are arranged both on the outer and on the inner face of the vessel and are energised in such a way that the direction of the magnetic flux produced by both sets of turns along the principal axis of the vessel is the same. Magnetic compression forces do not tend towards zero even towards the end of the compression stage, because the degree of magnetic coupling between the primary winding and the sec. "winding" or stream of plasma tends towards a finite value. Thus the plasma is maintained enclosed and in a stable position.

Title: Vibrator assisted grain milling equipment - uses shaped milling body adjacent rollers to give constantly varying milling gap
IPC: B02C1/08
Filed: 1978-06-22
Abstract: The milling equipment has a concave milling body (2) supported against the upper roller (3) of a pair of milling rollers, the lower roller (5) being vibrated. The curvature of the inside face of the milling body is greater than the armature of the upper roller, so that the gap between them is wider at the top than at the bottom. The milling body is mounted on a horizontal spindle (1) at the bottom and is connected to a set of vibratory motors (10) at the top so that the vibrations cause the size of the gap to be continuously varied. When used for wheat and other delicate materials, the arrangement gives an improvement in the quality of the product. The size of the gap can be varied to suit the material to be ground.
