Title: Monitoring temp. of granular material - by static or scanning infrared sensors for display and control
Inventor: NEBEL HORST
IPC: G01K13/02
Filed: 1976-04-23
Abstract: Temp. measurement in heat treatment of granular bulk material such as cement, relies solely on the infrared radiation existing at the measuring point to produce a signal proportional to the temperature. an i.r. radiation sensor can scan the flow cross-section for the bulk material and/or for gases continuously or intermittently (stepwise). The i.r. measurement has a very short time of response. The measurement is less affected by high dust content in the gas. The same sensors can be used for all measuring points and one sensor can cover several points if arranged in a scanning mode.

Title: Heat sealing machine for battery cases - with slide tracks for removing hot platen and positioning replacement on carriage
Inventor: EBERLE WILLIAM J
IPC: B29C65/78
Filed: 1976-08-03
Abstract: A heat sealing machine for joining thermoplastic parts includes a heated platen on a movable carriage for advance to a position between the parts to be joined. Replacement platens are mounted in a fixed slide track at right-angles to the direction of carriage movement.

Title: Electronic pressure difference transducer - varies two supply lead current in square root characteristic for pressure difference flow measurement
Inventor: SCHICK GUENTER
IPC: G01D3/02
Filed: 1976-08-19
Abstract: The electronic pressure difference transducer processing network varies the current in a two wire supply lead according to the square root of the pressure difference between two monitored points, for flow measurement. The network is supplied with current by two wires only (1, 2) which also serve as the signal carrying medium. A current regulator (7) for null current setting, and a suitable voltage generator (8) supply suitable voltages to a basic transducer circuit (3), amplifier (4) and square root law processing circuit (5). This feeds a voltage to current amplifier (6) and this in turn affects the current in the supply and signal leads (1, 2) in the manner required.

Title: Tidal flow driven power plant - uses four large reservoirs with turbines in central flow channel regulated by locks for continuous conversion of energy
Inventor: NURK JOSEF
IPC: E02B9/08
Filed: 1977-05-12
Abstract: The plant converts tidal energy into electrical energy, using the incoming and outgoing waters acting directly or indirectly on generators. Four large reservoirs are constructed according to local requirements. The reservoirs are alternately emptied when the tide goes out, and filled when the tide comes in, creating a continuous conversion of tidal energy. To achieve this, a flow channel is constructed, through which passes all the water from the open sea, the tidal flats, and the reservoirs. The turbines are positioned in the centre of the channel. Individual phases of the water flow may be manually or automatically controlled by locks.

Patent DE-2730075-A1 (DE)
Inventor: DECKER HEINZ DIPL ING
IPC: B28B11/04
Filed: 1977-07-02
Abstract: The continuous cavities of blocks are filled with foam in order to improve the heat-insulating properties. For this purpose, the blocks are placed, with an opening side downwards, onto a conveyor belt, which has been coated beforehand with a layer of sand. In this manner, adhesion of the reaction mixture, to be introduced, or of the resulting foam to the conveyor belt is avoided. The upper surface of the blocks may also be sprinkled with granular material (sand), as a result of which better adhesion to the mortar when laying the blocks is achieved.
