Patent DE-3604724-A1 (DE)
Title: Switching mechanism for an electrical installation apparatus
IPC: H01H13/60
Filed: 1986-02-14
Abstract: The invention relates to a switching mechanism for an electrical installation apparatus for optional use as a push-button switch, momentary-contact switch, rocker switch or rocker momentary-contact switch, using a rocking element, which is in the form of a link, for operating a contact spring which can be moved into two switch positions. Said switching mechanism is operatively connected to a plunger of an operating element, in such a manner that, whenever operation occurs, the plunger strikes against one link surface, and in such a manner that a pivoting movement of the toggle element into its respective opposite position then takes place and an actuating element is allocated to the switching mechanism for optional use as a momentary-contact switch or switch. In order to develop a switching mechanism for an installation apparatus which can be used both as a switch and as a momentary-contact switch and which furthermore can be used in conjunction with different operating elements as a push-button switch, momentary-contact switch, rocker momentary-contact switch or rocker switch, the invention proposes that, in addition to interacting with the contact spring, the toggle element interacts indirectly with the actuating element which is arranged in the switch housing between the toggle element and the freely moving end of the contact spring.

Patent DE-3614726-A1 (DE)
Title: Sports wheelchair
Inventor: GOLOMBEK GREGOR
IPC: A61G5/10
Filed: 1986-04-30
Abstract: Sports wheelchair with a seating means (2) and a frame (1) which is releasably connected to the seating means via special retaining elements (9), and this permits easy exchange of the individual components. The connecting plate (13) is fastened on these retaining elements (9). The bevel (20) of the axle (6) results in the king pin angle of the rear wheels (3) and thus in a simplification because the king pin angle no longer has to be milled into the connecting plate. The retaining elements (9) are designed as clamps in the upper region and permit infinite displaceability of the seating means (2) and thus extreme manoeuvrability of this sports wheelchair. This wheelchair is particularly lightweight because of the small number of components. Since, moreover, few components are dependent on the width, the other components can be produced more cheaply and in a larger batch size. Due to the fact that the frame (1) is flat, the space requirement during transportation with the rear wheels (3) removed is much lower than for customary sports wheelchairs with a bulky box-shaped frame. <IMAGE>

Title: Apparatus for filling cracks
Inventor: HERMANN FRITZ
IPC: E04G23/02
Filed: 1986-07-28
Abstract: The apparatus for filling cracks or similar recesses by means of a free-flowing composition has a storage chamber (6c) into which the composition (8) is introduced. After filling the storage chamber (6c), a compressive force is applied by a force accumulator (5) and the volume of the storage chamber (6c) is reduced by displacing the composition (8) into the crack (1a) which is to be filled. This procedure can be interrupted at any time by eliminating the compressive force. <IMAGE>

Patent DE-3628412-A1 (DE)
Title: Lorry roof spoiler with vertically adjustable wind-deflecting shield
Inventor: WEIGL ADOLF
IPC: B62D35/00
Filed: 1986-08-21
Abstract: A lorry roof spoiler with a wind-deflecting shield supported such that it can be adjusted vertically with respect to the driver's cab via a plurality of vertically adjustable supports is characterised in that at least one of the supports is designed as a shock absorber, in particular telescopic shock absorber. As a result, the vertical adjustment is simplified as fewer supports have to be synchronously adjusted at the same time in the vertical adjustment. The shock absorber follows the vertical adjustment in a passive manner but secures the wind-deflecting shield against dynamic alternating stresses and prevents fluttering movements.

Title: Insert window, comprising a plurality of elements, as technical aid for installing and removing windows, for avoiding draught air
Inventor: MAYER LOTHAR
IPC: E04G21/28
Filed: 1986-10-17
Abstract: In order to prevent draught air or cold from penetrating into the rooms during the installation and removal of windows, use is to be made of an insert window which comprises a plurality of elements and can be fitted into the window cutout. Fitting can be carried out in a very short period of time since the window is designed such that it can be infinitely adjusted vertically and horizontally, this ensuring that a seamless fitting can take place.

Title: Process and apparatus for simultaneous SO2 and NOx separation downstream of combustion plants having a coke-precoat filter system
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/86
Filed: 1986-12-10
Abstract: It known to separate off SO2 and NOx downstream of furnace plants by coke bed packings. The reaction velocities and thus the reducing agent consumption are to be kept very low, that is to say in accordance with the particular activity of the coke used, whether bituminous coal coke or brown coal coke and depending on the specific preparation of the coke. It is further known that the reaction gas can in part pass through the coke bed as slip gas and produce impermissible pollution in the so-called pure exhaust gas. In order to select the velocity in the coke catalyst as high as possible, and, despite this, to separate off the slip gas and unseparated SO2 and NOx amounts, according to the invention it is proposed that downstream of a fossil-fuel fired boiler, which is provided with a dust separator and a flue gas desulphurisation system, is provided a coke catalyst which is provided at the discharge with a coke grinder and a transport system, preferably a pneumatic blow tank conveyor, which feeds the coke initially used by its coke grinding and blow tank device (6) to a contact section laid in parallel and/or horizontally and having vortex-inducing internals, and via this contact section, the coke is delivered to a downstream cloth filter of a precoat type and via a discharge element (9), the coke used for the second time is pneumatically [lacuna] via a blow tank (10) to the combustion chamber of the boiler (1)...

Patent DE-3706171-A1 (DE)
Title: Coextrusion head
Inventor: BECKER RUDOLF
IPC: B29C48/09
Filed: 1987-02-26
Abstract: In the case of a coextrusion head for forming multilayered tubular structures from plastic, with a torpedo and a plurality of manifold cores, the latter were hitherto either arranged axially with respect to one another around the torpedo, resulting in a considerable length of the head, or they were placed radially around the torpedo, resulting in an undesirably large diameter of the extrusion head. Furthermore, mixed forms of both arrangements are known. To obtain axially and radially small dimensions, the novel coextrusion head has manifold cores (10, 11) with, arranged on their outside or inside one above the other, in each case two manifold channels (17, 18, 21, 22) which are not connected. An annular channel (24, 29) in each case assigned to the lower manifold channel (18, 22) leads directly to the lower end of the manifold core, whereas the annular channel (20, 23) allocated to the upper manifold channel (17, 21) extends around the upper end of the manifold core at its side facing away from the feed bores (4, 5) to the lower end of the manifold core. Using two manifold cores (10, 11) all conventional tube structures with up to five layers can be produced, whereas with three manifold cores, tube structures with up to six layers can be produced. <IMAGE>

Title: Colour-matching luminaire
Inventor: KUEHL BERNHARD PROF DR RER NAT
IPC: G01J3/12
Filed: 1987-03-23
Abstract: The standard illuminant D 65 (artificial daylight) can to date be implemented only approximately. It is the aim of the present invention exactly to simulate the standard illuminant D 65 by partially filtering filament lamps. An exemplary embodiment shows that this is possible with the aid of four colour filters. A patent is claimed for an illuminating device with the aid of which each required spectral distribution (e.g. D 65, D 50) can be exactly simulated. For this purpose, the radiation from continuous radiation sources, preferably filament lamps, is filtered with the aid of at least two colour filters of which at least one does not cover the whole light output opening (partial filtering).
