Patent DE-2433890-A1 (DE)
Title: Extraction of heat from sources deep in the earth crust - previous method is improved so that one borehole now does the work of two
Inventor: BOETZKES MAX DR
IPC: F24J3/08
Filed: 1974-07-15
Abstract: The present improved method envisages a single borehole divided into two by a co-axial pipe, the water passing down the annulus between the pipe and the wall of the borehole and returning inside the pipe. It sees it as possibly worthwhile to abandon the lower section of the drill at the bottom of the borehole, rather than extract it and sink a lining in its place. The upper sections of the borehole lining and co-axial tube would be insulated against heat loss; the consequential narrowing of the water channel would accelerate the flow, reducing the time taken for the heated water to pass through the cold strata of the earth which lie above the hot spot.
Patent DE-2437033-A1 (DE)
Title: Bridge made from prefabricated concrete sections - has sections joined on site by concrete and reinforcing members
Inventor: HOLZAPFEL WERNER
IPC: E01D21/06
Filed: 1974-08-01
Abstract: The prestressed prefabricated concrete components are used especially for making of relatively low and short bridges over roads. The bridge sections are produced outside the actual erection site and are connected to each other by concrete on site. The sections are transferred to the site by a sliding support system which is detached from sections after they have been connected and preloaded. The sections are connected after they are all assembled on the actual position, and the section ends have chambers where the ends of reinforcement members overlap. The bridge sections can also have embedded tubes through which reinforcement members are threaded.

Title: Continuous coating of wood, chipboard, etc. - transfer of precured film from endless band under heat and press
Inventor: SCHWARZ GUENTHER DIPL CHEM DR
IPC: B05D1/00
Filed: 1974-08-12
Abstract: Flat surfaces of wood, chipboard, pulp, paper and fabric are coatted with paints, partic. thermosetting enamels, by prior application of a continuous film to an endless band, precuring and contact under heat and press. with the surface to be coated, so that the film adheres firmly to the substrate and is simultaneously sepd. from the endless band, the surface adjacent to the band forming the outer surface of the coated workpiece. Simpler than previous coating techniques. Enables effect of a laminate to be achieved without the need for prior prepn. of separate layers. Since film is precured, problem of absorption of liquid coating materials by wood, etc. is avoided.

Title: Industrial wastes extraction treatment - in extraction and distillation columns automatically controlled by densimeters and flow rate controllers
Inventor: NICOLOIU MIRCEA DIPL ING
IPC: B01D3/42
Filed: 1974-10-08
Abstract: An extn. plant for the recovery of materials during the treatment of industrial wastes consists of two or more extn. columns in series and a distillation column in which the extract is sepd. from the extg. agent. Extractive cleaning and distillative sepn. are controlled by pumps with by-pass lines which control the liq. phases to be contacted as a function od the output signal of sensors in the columns. This results in a continuous fully automatic extn. of wastes which arrive in fluctuating quantities and concns. The automatic control saves extn. agents and power in the subsequent distillation stage. The costs for supervision of the process are also lowered.

Title: Shuttle bobbin change control - has pre-set counter to activate bobbin change when given number of impulses registered from bobbin monitor
Inventor: HERZER GERHARD ING GRAD
IPC: D03D45/10
Filed: 1975-02-04
Abstract: In a process and appts. to generate a control signal to indicate that the shuttle bobbin needs to be changed, the wound yarn on the bobbin is monitored on each passage of the shuttle through a monitoring point, and the bobbin is changed after a pre-set number of control impulses have been registered. The system allows control of the weft yarn length remaining in the bobbin by adjusting the control signals according to the width of fabric being woven to reduce wastage through odd unusable weft yarn lengths. A counter, which can be pre-set, is located between the shuttle bobbin sensor and the bobbin change unit which activates the bobbin change unit only when the pre-set number of control impulses have been registered.

Title: Capacitive alarm circuit for surface protection - uses conductor loop coupled to capacitor such that penetration modifies characteristic frequency
Inventor: RODE JOHANNES ING GRAD
IPC: G08B13/12
Filed: 1975-06-28
Abstract: A security system for protection against forced entry through a surface e.g. door, wall, is effective against any form of penetration.

Title: High speed coiling of synthetic fibre tow into can - using rotating pneumatic gun whose outlet is inclined to absorb energy (BR210976)
Inventor: SCHIPPERS HEINZ DIPL ING
IPC: B65H54/80
Filed: 1975-09-09
Abstract: A device for coiling a tow of synthetic fibres into a can comprises a pneumatic gun rotating about a vertical axis above the can. The gun consists of a curved tube in which an air nozzle is located and through which the two passes. The tangent to the outlet of the tube is included to the radius of the circle of rotation at an angle of 30-80 degrees. The shape of the outlet of the gun reduces the kinetic energy of the tow, allowing the tow to be feed through the gun in excess of 1000m/min. without tightly packing the two in the can.

Title: Double glazing unit with internal mesh - with mesh protected from environment and with smooth surface for cleaning
Inventor: WEBER MATTHIAS ING GRAD
IPC: E06B3/66
Filed: 1975-11-25
Abstract: Double glazing unit comprises an internal mesh which is inserted in the air gap between the two panes, and which is therefore not exposed to chemical or mechanical environmental influences. It also provides a smooth surface which facilitates cleaning of the double glazing unit, as the panes are not interrupted by mullions or transoms, nor does an attached mesh have to be unscrewed or opened. As the mesh can be made of the most varied materials, euqalisation of expansion can be allowed for by applying a suitable equalising material e.g. spring, foam material, etc. to the head ends. The double glazing unit provides an optimum soln. in the reconstruction of old buildings, eliminating the cost and labour of providing a separate grid mounted in front of a window with a protective coating every 5 yrs..

Title: Fixing a trim bar to a roller blind casing - by bonding the former to the latter with plastics e.g. polyurethane foam
Inventor: WIEHOFSKY ALFRED
IPC: E06B9/17
Filed: 1976-01-24
Abstract: A trim bar is fixed to a roller blind casing by bonding the former to the latter with the aid of a plastic e.g. polyurethane foam. No fastening devices such as rivets or clamps or clips are needed. The process is not labour extensive, hence relatively inexpensive. The "U"-profiled trim bar is placed with its "open" side up. A thin strand of liq. plastics foam is introduced into the channel defined by the "U". The roller blind casing is pressed into the channel whereby the gaps between it and the edges of the casing are filled out by the foam which then adhesively bonds the components together.

Title: Firing equipment for pulverised fuel, such as lignite - using water injection into recirculating gas and combustion zone turbulence increased by steam nozzles
Inventor: WESSELY JOSEF
IPC: F23L7/00
Filed: 1976-05-08
Abstract: The firing equipment for pulverised fuel, partic. lignite, comprises burners (2) firing into the combustion chamber (1) and water nozzles (8) spraying into the entry of a duct (3) recirculating gas from the furnace exit (4). This water is preheated to about 90 deg.C, for rapid evaporation. The recirculated mixture is drawn into the pulveriser (6) where fuel from a feedline (5) is added and the whole discharged (7) to the burners. Additional nozzles (9) in between the burners allow steam to be injected into the combustion zone. Variation of the total amount/proportions of water from these two sources, permits limitation of the combustion chamber exit temp. to below the ash-softening figure, minimising gas path fouling. Combustion zone turbulence is also increased by the steam from the lower nozzles.
