Title: Process and apparatus for producing endless flat belts
Inventor: SEIFERT DIETMAR
IPC: B29C53/56
Filed: 1981-11-25
Abstract: The present invention can be applied in particular to the production of endless flat belts having a power-transferring textile insert and plastic covering. The aim and the object of the invention is to provide a process and an apparatus for the production of high-quality homogeneous flat belts of any dimensions. The way in which this is achieved according to the invention envisages a spiral construction of the flat belt comprising sheet-like structures in web form which are covered on both sides and cut to the requisite width, with the sides of the web to be joined being plasticised. On the apparatus side, the spiral construction of the flat belt is brought about by a drive roll with associated compression rolls and a deflection roll mounted in a displaceable bearing block. The plasticisation of the web sides to be joined is performed by means of appropriate heat sources. <IMAGE>

Title: Carburettor control device
Inventor: TAKADA SHIGETAKA
IPC: F02M1/12
Filed: 1981-12-22
Abstract: A carburettor control device with an electrically heated automatic choke and a device for rapid idling is proposed. The automatic choke has first means fed by the battery for generating heat, a first temperature-sensitive part, which is deformed in the heating process of the first means for generating heat and which controls the position of the choke valve as a function of the deformation. In addition the carburettor control device comprises second means for generating heat fed from the battery, a second temperature-sensitive part, which is deformed in the heating process of the second means for generating heat and which controls the position of the throttle valve as a function of the deformation, a control circuit connected between battery and first and second means of generating heat and a heat sensor for detecting the external temperature. The control circuit has a comparator device for comparing the voltage derived from the heat sensor with a predeterminable reference voltage and a supply circuit, which controls the level of the voltage fed to the first and second means of generating heat as a function of the output signal of the comparator device. <IMAGE>

Title: Ice breaker or ice-negotiating ship
Inventor: HAGIN FAUST DIPL ING
IPC: B63H23/32
Filed: 1982-01-29
Abstract: An ice breaker or an ice-negotiating ship, with propulsion arrangement consisting of at least one thermal propulsion machine which drives a controllable-pitch propeller via reduction gearing, is to be designed to the effect that an improved ramming operation is possible and longer life of the propulsion machine is ensured. To this end, an auxiliary propulsion arrangement is provided which comprises variable gearing, a stored-energy flywheel, a gearing-ratio adjusting device as well as a control device by means of which the gearing-ratio adjusting device can be controlled independently of the propeller torque. This auxiliary propulsion arrangement can be coupled when required to the main propulsion line of the ship and then enables the propulsion machine to be operated with approximately constant speed and power in ramming operation of the ship during a propeller blade adjustment from "full ahead" to "full astern" or vice versa and enables the excess energy generated by the propulsion machine to be directed into the stored-energy flywheel to increase the speed of the same. This energy stored by the stored-energy flywheel can then be delivered, in addition to that of the propulsion machine, to the propellers for briefly increasing the propeller torque.

Patent DE-3225689-A1 (DE)
Title: Glass block
Inventor: MAAHSEN JO
IPC: E04C1/42
Filed: 1982-07-09
Abstract: The invention of the patent of addition relates to four glass blocks, developed according to the main patent, having additional webs at the outer edge of two touching peripheral faces, which are welded together homogeneously to form a quadruple glass block, a crosswise-arranged welding lip thereby resulting instead of the customary mortar joint. Inside the quadruple glass block, the opening for the reinforcing bars is of smaller dimension than outside and, after welding, forms a cavity which can be filled with mortar adhesive or another water-impermeable material. Also, the glass block edges are thinner on the inside than on the outside on the peripheral faces. These homogeneous quadruple glass blocks are laid on the remaining outer peripheral faces with mortar adhesive and reinforcing bars to form glass-block walls with joints of </= 3 cm. In the case of smaller walls, the customary concrete border can be dispensed with and instead of it the quadruple glass blocks are directly installed into a metal U-profile, running all the way round, with mortar adhesive and sealing means. The reinforcing bars, which are threaded at both ends, are passed through drill holes located at regular intervals in the metal U-profiles and firmly screwed to nuts.

Title: Device for heating or cooling a liquid
Inventor: ALTMANN UWE
IPC: F01P7/04
Filed: 1982-09-01
Abstract: The device for changing the heat content of a liquid consists of a control unit (A) in which a pressure limiting valve (15) and a control slider (22) are arranged. A pump (10) conveys pressure medium from a container to the control unit and to a hydraulic motor (13). When the conveyed pressure medium has reached an upper limit due to throttling at the pressure limiting valve, the control slider is switched by an expansion material element (19) into a position in which further throttling, and hence heating of the pressure medium, is interrupted. The device can be used for the cooling of a liquid by means of a heat exchanger by altering the speed of a fan, or for the heating of a medium which likewise gives up its heat to the heat exchanger (16). <IMAGE>
