Title: Wind-surfer with removable centre-board - has grooves for swivel pins along backward-sloping forward face of housing slot and faces of slot are parallel
Inventor: HUESS OTTO
IPC: B63B41/00
Filed: 1978-01-18
Abstract: The windsurfer with a removable centreboard has the usual slot (2) through the hull, fully housing the board and with backward-sloping blind grooves (5) for its swivel pins (4).

Title: Heat engine using air heat - comprises two cylinder machine giving adiabatic expansion followed by isothermal compression
Inventor: GENSWEIN GEB SCHMITT ANNEMARIE
IPC: F03G7/04
Filed: 1978-03-22
Abstract: The heat engine uses air heat, comprising a two-cylinder piston machine in which the air undergoes a three-stage quasi-open process - adiabatic expansion, followed by isothermal compression and isobar heat absorption. To remove the waste heat released on isothermal compression a heat pump is inserted. This transfers this heat to the cold air leaving the machine, including the compression heat of the heat pump with a relatively small temp. drop.

Title: Controller for small commutator motor - incorporates several series chokes to limit fault current levels to safe value
Inventor: PETSCHENKA EDWIN DIPL ING
IPC: H02P7/281
Filed: 1978-04-28
Abstract: The controller is able to drive the machine in four quadrants. The operation is determined by the switching of transistors (T1, T2; T3, T4) in the usual manner. To limit the current due to simultaneous operation of transistors in series across the supply (T1, T4; T3, T2) chokes (L1, L1'; L2, L2') are connected in series with each transistor and the motor. Flywheel diodes are associated with the chokes, (D1-D4). As the current through the chokes is unidirectional there are no magnetising losses. The rate of rise of fault current is however limited by the chokes.

Title: Telephone switching circuit with intercept facility - has detector sensing voltage drop to enable called subscriber to seize call even if caller hangs up
Inventor: SEIDEL GUENTHER
IPC: H04Q3/00
Filed: 1978-09-20
Abstract: The telephone circuit enables a duly authorised second subscriber which is called by a first to seize to call even if the first subscriber hangs up. When the caller hangs up a voltage drop occurs across two series resistors connected across the input of a detector circuit. To differentiate between clearing and dialing pulses, an intercept signal is applied to the group selector and the tariff pulses are suppressed. The negative potential occuring after a clearing pulse is used. If this does not occur after the max. time allowd for the clearing pulse, the intercept signal is removed.

Title: Coal drying process without flue gases - using microwave radiation inside enclosed tunnel
Inventor: STRUNZ DIETMAR DIPL ING
IPC: C10B57/10
Filed: 1979-03-01
Abstract: A process for drying a ground or unground coal continuously or discontinuously is based on electromagnetic microwave energy to which the material is exposed. The coal is heated to is not >105 degrees C and care is taken that the ambient air has no access to the tunnel enclosure in which the irradiation takes place. This prevents the overheating and oxidation of the particle surfaces which is inevitable in the case of indirect drying by flue gases or hot sand and which has a detrimental effect on the coking properties. Environmental pollution is also eliminated.

Title: Rotary rocket engine gas flow control - uses guide vanes on converging part of nozzle to prevent increase in swirl velocity of gases
Inventor: DIESINGER WALTER HELMUT PROF D
IPC: F02K9/32

Abstract: The engine has a cylindrical housing (2) within which there is a solid fuel bed (13). The housing tapers from the end of the full bed to the inlet (14) of the jet nozzle (15) and the nozzle tapers outwards again from this point to its outlet. There are guide vanes (9, 11) between and front end (12) of the full bed and the inlet of the nozzle, which extend radially and guide the gases to the nozzle inlet so that, as they converge, the axial velocity increases without an increase in the swirl velocity. The vanes may be straight or curved as necessary to achieve this.

Title: Thermopile stack assembly - has clamped element plates separated by insulators and has contact strips interposed
Inventor: BOJAK KURT DIPL ING
IPC: H01L35/32
Filed: 1979-03-31
Abstract: The simplified thermopile ensures a cost reduction and uses clamped plates instead of welded joints to provide the electric contact. This leads to low manufacturing costs since the plates can be cut to size or stamped for the pile assembly. The pairs of the thermopile are made up of copper and constant or other combination of metals, including the semiconductor types. Clamping is made with interposed contact strips and insulators while extension ribs provide the necessary cooling of the cold junction. The insulation layers (4) between the element plates (1/2) either extend to full length except for the contact strip (3), or leave a central cavity between the plates. The cavity can be used for cooling.

Title: Framed manhole cover support system - has emergency edge supports in contact only if a main support gives way
Inventor: EICHELMANN HORST DIPL ING
IPC: E02D29/14
Filed: 1979-06-25
Abstract: A lid, insertable in a frame, is support only at pref.three separate points of its periphery by bearing surfaces of its own and of the frame working together, in a cover for a shaft. Here there are additional auxiliary bearing surfaces on the frame and lid, working together to prevent the lid from falling through the frame. They are not in contact with each other when the lid is supported on the main bearing surface. The frame inside surface and lid outside surface pref. form a vertical gap, while the auxiliary face is formed by a peripheral flange protruding inward from the frame, or outward from the lid, across it. This reliably prevent the lid from tilting or falling through, in the event of breakage of a support.
