Title: Continuously variable speed friction drive - conical roller system transmits high powers with low wear rates
Inventor: NASVYTIS ALGIRDAS LEONAS
IPC: F16H15/46
Filed: 1974-03-01
Abstract: Gears on a drive shaft rotate a sub-box containing two rings with conical internal faces which can be moved apart axially by threaded rods, each driving duo-conical rollers on a ring connected to the output shaft. Further gears connect the drive shaft to a central shaft connected via conical faced rings to the conical rollers, also be moved axially by screwed rods. Drive power is thus split and transmitted to the conical rollers via the several different conical contact faces geared, maintaining contact with the rollers.

Title: Timber cutting and stacking - transports partial stacks of timber transverse to their long direction and pushes separate stacks onto platform(s)
Inventor: GRENZEBACH RUDOLF
IPC: B65G57/18
Filed: 1975-01-11
Abstract: The stacking process starts by cutting through a stack of plates in longitudinal or transverse direction, in order to form adjacent partial timber stacks. The rows of partial stacks are transported by a conveyor with increasing speed in a direction across their longitudinal axes, so as to form increased spacings between the individual partial stacks. Then the latter are pushed, transversely to their transport direction, onto a platform which can be lowered to a depth corresponding to the height of an already deposited stack. Preferably separate platform are provided for stacks of different lengths of timber. Two conveyors may be used, the second one being of angled configuration.

Title: Line driver for digital data transmission systems - has R-C network coupled to sender output connected to twisted pair transmission line
Inventor: WITTENBURG JOACHIM
IPC: H04L25/03
Filed: 1975-08-22
Abstract: A line driver circuit for digital data transmission systems permits long line transmission with a min. of signal distortion. The input signal (e) of 5V is used to switch a NAND gate (N) and generates complementary outputs (a, a') over two arrays of transistors (T0 to T5) and (T0' to T5'). Signal transmission to a receiver (E) is over a twisted pair transmission line (1, 1'). The sender (S) has the complementary outputs processed over an R-C network, consisting of two series resistances (R, R2) and R1, R2) in each line with parallel capacitors (C1, C1'). Suitable sizing of the R.C network ensures that the maximum permissable surge current of the drive transistors is not exceeded. The circuit together with the receiver input stage (RA, CA) provides correct line impedance matching.

Title: Arc furnace boiler bases - using shapes which can replace expensive spherical bases
Inventor: BUEHLER KARL
IPC: F27B3/06
Filed: 1976-03-18
Abstract: Base for a furnace boiler, esp. an arc furnace boiler, the novelty being that at least one part of the base forms a developable surface. The pref. surfaces are (a) a curve, i.e. a segment of a circle; or (b) a segment of a polygon resembling the arc of a circle; or (c) is formed by two pieces, each consisting of part of a cone or a pyramid. The invention is desired to replace the spherical bases normally employed to provide the required rigidity and strength on pressurised boilers, because such spherical bases are expensive to mfr. The new bases provide the rigidity required, but are simple and inexpensive to mfr., as neither hot forge-pressing nor special machines are necessary.

Title: Two-phase flow measurement with separate radioactive tracers - for liquid and gas is suitable for steady or non-steady flows
Inventor: LOEFFEL RUDI DIPL ING
IPC: G01F1/74
Filed: 1976-04-07
Abstract: A separate tracer is injected in a short pulse for each phase and, at a distance from the point of injection, the activity throughputs or concentrations of all the injected substances are measured at least two points by a radio tracer method; the density of the phase mixture is measured by a gamma absorption method. Pref. short-life radio nuclides are used; Ar 41 for the gas phase and Mn 56 for the liquid phase. To provide clear separation between the two tracers, the scatter peaks which occur near the main peaks in the activity concentrations for each tracer are eliminated in the other measuring channel. The advantages of tracer measurement, of insensitivity to variations in press. temp. and concn. are utilised in two separate measurements for the two phase of the flow.

Title: Collector converting solar heat into energy - has corrugated channel forming lenses to evaporate substance to drive turbine
Inventor: JUETTNER KLEMENS
IPC: F24S23/00
Filed: 1976-04-22
Abstract: the method of converting the heat of the sun into mechanical energy employs roof panels which incorporate a comparatively small bore tube or channel for conveying a substance which evaporates easily. The heat of the sun evaporates the substance which is pumped around a circuit to pass through a turbine followed by a cooler. The channel follows a zig zag shape, passing through a multiple lens formation of the collector panel. the lenses may be in form of a set of corrugations or a series of bulbous protuberances with a hollow core forming the flow channel.

Title: Sanitary ware with high quality plastics inner shell - has outer support shell with interspace filled with suitable substance
Inventor: REEH KURT DR ING
IPC: A47K3/02
Filed: 1976-04-24
Abstract: Sanitary ware such as a bath tub is provided with an inner shelf (7) of a high-value plastics which is mounted inside spaced from a self-supporting outer shell (2). The interspace between the two shells is filled with a filler (4) such as a plastics foam injected into the cavity and an adhesive applied to the inner shell before the two shells are fitted together. The inner and/or outer contours of the outer shell (2) can be ribbed to provide greater stability. Since the outer shell and filling provide adequate support and stability the inner shell can be made very thin so that less high-value plastics need to be used, thereby reducing costs.

Title: Safety device for hydraulic or pneumatic installation - has rotating piston to connect inlet and outlet to atmos.
IPC: F16P3/22
Filed: 1976-04-28
Abstract: The safety device for hydraulic or pneumatic installation consists of a piston (1) with three circumferential grooves (2, 3, 4).
