Patent DE-3326927-A1 (DE)
Title: De:infestation of bulk commodities in bin
Inventor: FRIEMEL WOLFGANG DR
IPC: A23B9/18
Filed: 1983-07-26
Abstract: Gas is released by the hydrolysis of a metal phosphide over a period of 0.25-20 days. The commodity is stored in a bulk container vessel, bin, silo, ship hold or railway truck with a head space above the commodity. Phosphine gas is released in the head space beneath a duct with a fan which can draw gas from the head space and discharge it into the base of the container to deliver the gas to the bulk commodity. The fan is operated periodically for a duty cycle which prevents the build up of phosphine gas to the auto ignition point in the head space. Pests are eradicated from beans, peanuts, soya beans, cocoa beans, or coffee. The phosphine is recirculated through the bulk commodity without danger of auto-ignition.

Title: Method for regulating an asynchronous machine, which is supplied by means of a current-impressing intermediate circuit converter, in the field-suppression range
Inventor: JOETTEN ROBERT PROF DR ING
IPC: H02P21/08
Filed: 1984-03-29
Abstract: The method described in the prior application for use with voltage-impressing pulse converters is modified for use with current-impressing intermediate-circuit converters. The indirect flux and speed regulation constructed in accordance with the prior application specifies the spatial angle of the stator current vector. An invertor controller, which is designed predominantly digitally, causes the angle of the actual value vector to follow the desired angle as quickly as the maximum switching frequency of the invertor allows. If the frequency falls below an adjustable minimum frequency, the controller carries out the intermediate-phase pulsing, which is known per se, in order to reduce the torque ripple. The angle error occurring as a result of the commutation delay and the commutation itself is corrected after every commutation. <IMAGE>
Patent DE-3412721-A1 (DE)
Title: Windsurfing simulator and trainer
Inventor: SCHLENZIG WOLF-DIETER ING GRAD
IPC: A63B69/00
Filed: 1984-04-04
Abstract: The object of the windsurfing simulator and trainer is realistic instruction with easily reproducible movement sequences which correspond to the actions of windsurfers on the water. These actions are reproduced by the rubber/metal bearing in combination with a radial hydraulic endless damper. The movement properties of a windsurfer, behaviour of different sails, changes of course and the weight of the athlete are simulated. As a result of changes in the turning resistance by means of a radial hydraulic endless damper, slow or fast turns and changes of course can be executed, depending on the athlete's level of proficiency. The strength-sapping actions of standing upright and starting out of the water are omitted. Safety for the beginner is much higher with realistic training. Any surfing school will be able to adjust or equip the windsurfing simulator and trainer to meet its requirements.

Patent DE-3417749-A1 (DE)
Title: Barrel-finishing apparatus
Inventor: TEMME KARL
IPC: B24B31/16
Filed: 1984-05-12
Abstract: The invention relates to a barrel-finishing apparatus having a barrel-finishing container (10) which can be moved upwards out of its barrel-finishing position and about a horizontal tilting spindle (7) into the emptying position above a screening path. For its part, the screening path can be tilted upwards into an emptying position above the barrel-finishing container located in the barrel-finishing position and extends above a receiving chamber (25) for the machining bodies, the floor of which chamber is configured as a chute terminating above the barrel-finishing container (10). The invention proposes, in particular for achieving a favourable structural shape, that an emptying opening (E), of the receiving chamber (25), which is closed by a flap and is located between the screening channel (37) and tilting spindle (7) be provided and a sliding surface (17) be located between the tilting spindle (7) and the barrel-finishing container (10), with the result that the medium can thus be moved back and forth over the spindle (7). <IMAGE>
Patent DE-3420760-A1 (DE)
Inventor: DEDDEN HUBERT DIPL ING
IPC: C12M1/34
Filed: 1984-06-04
Abstract: An illuminating device with a diffused, radiating, surface light source (3) and an aperture system positioned between the light source and the object is provided. The aperture system is formed by two optically complementary aperture screens (4, 5) which are disposed in series, and are spaced apart. The first aperture screen (4) thereby consists of a large number of transparent circular discs (8), positioned at intervals on an opaque base, and a second aperture screen (5) consists of a large number of opaque circular discs (9), positioned at intervals on a transparent base. The diameter of the opaque circular discs (9) is larger than that of the transparent circular discs (8), so that the circular discs of the two aperture screens (4, 5) overlap in the projection. The microbiological structures used generally have a large number of almost circular areas which are positioned in a regular surface pattern on a transparent base or round one or some relatively large circular transparent areas on a light-dispersing base. With the illuminating device according to the principle of the complementary aperture screens, the contrast of such microbiological structures in relation to the base could be substantially improved.

Title: Integrated coal-drying device for steam boilers or fluidised-bed furnaces
Inventor: WIESER RUDOLF DR
IPC: F23K1/04
Filed: 1984-09-11
Abstract: The object of the invention is to increase the efficiency of those caloric power station blocks which are heated with very wet coal. For this purpose, an integrated coal-drying unit is proposed, in which the coal-drying chambers located between the coal bunkers and the furnace are heated by bleed steam from the steam turbine. The efficiency of the caloric block is improved by this combined power/drying process. A further essential advantage of the invention is that the fumes and carbonisation gases, formed during drying of the coal, pass into the combustion chamber or into the fluidised-bed furnace of the steam boiler. This reduces pollution of the environment by these materials.   During operation, inert flue gas flows through the drying chambers and, if present, the coal mills, and the fire risk due to the coal broken up beforehand and the explosion risk due to the pulverised coal are avoided. <IMAGE>

Title: Hybrid circuit on a flexible carrier material, and a method for its production
Inventor: HOFFMANN HORST
IPC: H05K1/18
Filed: 1984-11-23
Abstract: The hybrid circuit, in SMD technology, uses a flexible carrier material which has conductor tracks and connecting surfaces (2, 3, 4, 5) on at least one side and is folded over along a centre line or folding line (11), once the components (10) have been soldered on. In consequence, a hybrid circuit is produced which is fitted on both sides and has a flexible carrier material. Solder tabs, solder pins or braided cables are soldered onto the edges (5 and 6) which overlap after folding, and possibly also onto the conductor-track sections (2, 3) in the region of the folding line (11). <IMAGE>

Title: Screen-like covering for roof gutters
Inventor: HOFFBAUER LOTHAR U
IPC: E04D13/076
Filed: 1984-05-04
Abstract: Soiling in roof gutters prevents smooth water discharge. In order to prevent this soiling screens are required. Screens only work when they are clean. The invention of the screen-like covering for roof gutters is based upon the fact that, by virtue of its shape and the way in which it is attached in the second or following rows of roofing tiles, it permits soiling to trickle away or to be rinsed off by rainwater. The screening effect is thus retained over a considerably longer period of time.

Title: Oil cooled trunk piston of an internal combustion engine
Inventor: LINDNER HORST DIPL ING
IPC: F01M1/08
Filed: 1985-03-30
Abstract: Oil serving for cooling is fed under pressure to an oil-cooled trunk piston of an internal combustion engine, coupled by way of a piston pin to a connecting rod and by way of the latter to a crankshaft journal, from feed ducts of the crankshaft journal by way of ducts in the connecting rod bearing and connecting rod shank and in or around the piston pin and through a spray bore running coaxially with the connecting rod longitudinal axis. The cooling oil flow is introduced into a piston cooling chamber by way of a cooling oil passage hole, which in the admission side entry area widens like a funnel towards the small end such that the cooling oil flow emerging from the spray bore and moving to and fro due to the connecting rod motion always enters the cooling oil passage hole where it can be directed by the wall of the funnel-like entry area in the direction of the piston cooling chamber. At the same time at least those wall sections of the funnel-like entry area of the cooling oil passage hole along which the cooling oil flow passes in the direction of the piston cooling chamber have a parabolic contour.

Title: Storage installation for low-pressure gaseous media
Inventor: MANAHL ROBERT DIPL ING
IPC: F17B1/02
Filed: 1985-04-12
Abstract: The storage installation is provided for low-pressure gaseous media, in particular in fermentation-gas installations. It has a sack-like container (9) which consists of flexible material, for example gastight plastic sheets. This sack-like container (9) is arranged in a roofed housing (2). In the base region of the container (9) there is made an opening (15) to which a gas-supply line or gas-discharge line (16) can be connected. The sack-like container (9) is suspended on the housing (2) by means of its upper side. Its base is fixed, at least in the region of its inlet or outlet opening (15), on a foundation slab (1) on which the housing (2) rests. The sack-like container (9) is only loaded by its own weight and, in the absence of gas pressure, it hangs freely and loosely downwards. With increasing gas pressure, the container (9) gradually inflates until it fills the space which is delimited and enclosed by the housing (2). The structure is extremely simple and thus cost-effective, this being of particular import if such storage installations are used in agricultural fermentation-gas installations. <IMAGE>
