Patent DE-3407384-A1 (DE)
Title: Method of producing a tubular underground hollow space, e.g. a traffic tunnel, and apparatus for carrying out the method
IPC: E21D9/06
Filed: 1984-02-29
Abstract: In a tunnel, an intermediate layer (10) of clay mineral is arranged in an intermediate space between the tunnel lining (6) and the rock (11). This intermediate layer (10) is placed in advance of the lining (6) in the course of the driving into the intermediate space between the rock (11) and intermediate formwork (14) serving as an inner boundary. Directly following this, the lining (6) is produced in-situ by placing concrete in the intermediate space between the intermediate formwork (14), which is carried along in accordance with the concreting advance, and inner formwork (5). The placing of both the intermediate layer (10) and the cast-in-situ concrete lining (6) itself is thus effected directly following the advance of the driving shield, the fresh concrete of the lining (6) in a boundary line (29) coming into direct contact with the material of the intermediate layer (10) in accordance with the carrying along of the intermediate formwork (14).

Title: Method and device for cooling hollow rolls
Inventor: FRITZSCHE THOMAS
IPC: B21B27/08
Filed: 1984-06-12
Abstract: The invention relates to the cooling of hollow rolls, which are provided with a cooling-water feed tube arranged along the longitudinal axis of the roll and passed through the coolant outlet hole in an axle stub into the interior of the roll, in particular those for roll-type refining machine for the fine comminution of cocoa and chocolate masses, dyes and similar materials to be processed.

According to the method, a gaseous medium is fed into the roll interior in addition to the cooling water, the quantity of gaseous medium per unit time being greater than the quantity escaping with the discharge of cooling water, the level of liquid in the roll interior being kept constant at a level below the upper edge of the water discharge opening. The main features of the device are that an air delivery tube projecting into the roll interior is arranged on the cooling-water feed tube, parallel to the latter, and extends over a quarter of the roll interior. <IMAGE>

Patent DE-3433321-A1 (DE)
Title: Clock system for control systems with digital information processing
Inventor: STICKEL LEO DIPL ING
IPC: H03K5/1536
Filed: 1984-09-11
Abstract: The invention relates to a clock system for control systems with digital information processing. The object of the invention is to implement a clock system for a control system with digital information generation in which a phase-synchronous processing of the digital information is carried out at the zero passage of the mains voltage of the power component, thereby minimising the cost of eliminating the effects of noise and thus of suppressing noise. 
<??>This is achieved by using a monoflop to shift the phase angle of the mains voltage, which is converted via optocouplers or transformers and threshold value switches into a square-wave voltage, in such a way that the clock coincides precisely with the zero passage of the mains voltage and the clock width is then set via a further monoflop.
Patent DE-3439515-A1 (DE)
Title: Permanent rotary combustion system, permanent exhaust afterburning
Inventor: GUKELBERGER DIETER ING GRAD
IPC: F23C9/00
Filed: 1984-10-29
Abstract: The central aspect of the invention is the rotation of the combustion gases in the energy conversion of thermodynamic processes. In terms of construction, the rotary combustion of solid, liquid and gaseous fuels is achieved in that the combustion gases are not led off outside immediately after leaving the area of the combustion chamber but are continuously fed to the combustion chamber via a rotary circuit closed for part of the time. The correspondingly formed exhaust gas rotation ducts allow the permanent exhaust gas afterburning to be maintained even with the exhaust valve open by utilising the "Venturi effect". The centrifugal or centripetal acceleration of the combustion gases inevitably occurring also increases the thermal and kinetic components of the power output side without imposing a load on the power consumption to the same extent. Compared to the prior art, this concept achieves not only a high burn-up rate without soot and with a pronounced carburation effect and thereby a reduction of the exhaust pollutant emission but in addition produces an increase of the power output and a reduction of the specific fuel consumption. The spheres of application include drive and heating purposes, and the combination of these, combined heat and power.
Patent DE-3445264-A1 (DE)
Title: Heading machine with swivelling support traverse
IPC: E21D11/40
Filed: 1984-12-12
Abstract: During the driving of roadways in the seat stone, a heading machine can be advantageously used for placing complete canopy screens even if the roadway has transverse inclination. To this end, the traverse carrying the support segments is equipped with a swivelling supporting tube which in turn carries the pockets accommodating the support segments. Single-acting working cylinders serve as the swivel drive rotating this supporting tube. The working cylinders are attached to the fixed traverse part designed as a casing tube and act on a swivel part arranged therein, which in turn again acts via a rotary tube designed as a square tube on the supporting tube accommodating the pockets. The working cylinder bringing about the longitudinal displaceability of the supporting tube is accommodated in the rotary tube designed as a square tube, so that accurate adjustment in all necessary directions is possible by means of such a heading machine. <IMAGE>
