Title: Heat treatment furnace utilises fuel combustion flame - has ceramic plates within high velocity flame ensuring radiant heat transfer
Inventor: SHINOHARA YOSHIAKI
IPC: F27D99/00
Filed: 1978-07-24
Abstract: The heat treatment furnace is used for heating of components by flames generated on burning fuel. The heat transfer is ensured by convection in the combustion flames at high temp. The convection currents move with high velocity and they are efficiently utilised. This ensures a central region in furnace which is at a high temp. and energy is saved by the highly efficient heat transfer in this region. A heat transfer converter consisting of heat resistant bodies is arranged within the combustion flame. This convertor is heated by convective heat transfer by the high temp. flame moving at high velocity. Heat is transferred by radiation to the body to be heated. The converter consists of flat plate elements fitted within the flame of the burner. These plates can be made of ceramic fibres. Arrangement is partic applicable to the continuous heat treatment of steel slab and plates.

Title: Programme monitoring system for use with processors - has continuous check on programme cycle using decoded addresses which produce output on demand by memory-write signal
Inventor: KLEINERT HELMUTH
IPC: G05B19/042
Filed: 1978-10-23
Abstract: The programme monitoring system is for use with computer systems and permits a continuous check for errors. A microprocessor is coupled to a read-write memory (M) over a bidirectional data bus (BUS2) and an address bus (BUS1). Addresses are transmitted to a decoder that generates an output when a memory write signal (MEMW) is produced. An AND gate (G1) provides a signal to trigger two successive monostables (MF1, MF2) set to respond with a selected period. A second AND gate (G2) processes a second decoder output and the memory write (MEMW) signal. This error indicating signal is used as a reset for a flip-flop (FF). The set and reset cycle occurs continuously throughout the length of the programme to provide immediate detection of any programme error.

Title: Recording speech on track already having music background - using advance replay head to feed signal into delay network and allow mixing with in coming signal (OE 15.3.79)
Inventor: STEJSKAL KARL
IPC: G03B31/00
Filed: 1978-12-05
Abstract: The sound cine film replaying system enables speech to be recorded on a previously recorded music magnetic sound track. Variable delay and cueing options are incorporated. A signal is replayed through one head and fed into a delay network. The output from the latter is mixed with another incoming signal in a mixer for re-recording through a second head. The delay period of the network is adjustable and the system can also be used for detecting a cue signal with the first head which is already on the sound track and using it to initiate recording through the record chain.

Title: Machine tool with overhung vertically sliding beam - has hydraulically loaded tie rod to exert counterbalance moment
Inventor: LOTHMANN FRANZ
IPC: B23Q11/00
Filed: 1979-02-09
Abstract: A machine tool has an overhung beam which can slide up and down a vertical column. The dead weight of the beam and the tool slide is counterbalanced by a weight inside the column. The movement of the slide exerts a varying bending moment on the column causing it to deflect with consequent inaccuracy of operation. This variable bending moment is counterbalanced by a tie rod connected to hydraulic jack. The pressure in the jack cylinder is controlled by a transducer which senses the position of the slide.

Title: Heat resistant structural element - with central glass wool layer protected by expanded glass blocks and wire mesh
Inventor: KRAEMLING FRANZ DR
IPC: E04C2/284
Filed: 1979-03-30
Abstract: A heat resistant structural panel, made of incombustible materials, consists of a base plate of asbestos cement which is sepd. from the cover plate of prestressed silicate glass by a layer of several centimetres thickness of rock wool or glass wool. The layers are bonded to each other by an organic weather resistant adhesive on the base of polychloroprene rubber. The adhesive layer on the glass side carries an embedded wire mesh.
