Patent DE-3821611-A1 (DE)
Title: Method for producing furniture parts with at least one rounded edge, and furniture part
Inventor: RECKORD GEB KIRCHHOFF
IPC: B27G5/00
Filed: 1988-06-27
Abstract: The production of furniture parts or the like, such as furniture bodies, with at least one rounded edge takes place in that a shaped groove is milled into a panel, the shaped groove having diverging flank portions rounded towards the front of the panel. Thereafter, the panel portions on both sides of the shaped groove are folded towards one another about a flexible strip in the manner of a film hinge from the flat 180-degree starting position to enclose a smaller angle than that. Such furniture parts are to be produced simply, quickly and above all with an improved surface in the region of the edge rounding. For this purpose, the shaped groove is cut in from the back of the panel, the depth of this groove being smaller than the thickness of the panel and, as a result, a web remaining towards the front of the panel, which forms the film hinge-like strip.

Title: Pallet container
Inventor: SCHUETZ UDO
IPC: B65D77/04
Filed: 1988-11-24
Abstract: The pallet container according to the main patent (Patent Application P 3819911.4) can still be improved in respect of its stability and the automated production of the grid casing. The design of the new pallet container is to take account of these improvements. The pallet container has a wooden pallet or a tubular steel pallet on which an inner container made of plastic with a casing of vertical and horizontal grid bars (4, 5) of tubular steel is fixed, said grid bars forming continuous inner and outer tangential planes (20-20, 25-25). At the junctions (15), the grid bars are tapered to form trough-like depressions. This shaping causes four contact points (22) located in one plane (21-21) with in each case a material accumulation corresponding to the fourfold wall thickness of the grid bars to occur at each junction (15). The grid bars (4, 5) are connected to one another by resistance pressure welding at the junctions (15) in the region of the contact points (22). The pallet container can be used as an operationally reliable reusable container for liquid products of any kind. <IMAGE>

Title: Motor vehicle heating by means of petrol using a catalyst
Inventor: GRIESSER LOTHAR DIPL ING
IPC: B60H1/22
Filed: 1989-01-16
Abstract: Engine-independent vehicle heating has hitherto usually been carried out by combustion of motor fuel in a flame. The high flame temperatures require complicated apparatus and the use of expensive materials. In addition, environmentally polluting oxides of nitrogen are formed in combustion in a flame. The reaction of motor fuel, in particular lead-free petrol, proceeds over the catalyst used at temperatures as low as 100@C. This gives no environmentally polluting oxides of nitrogen. The vehicle heater using the catalyst consists essentially of the reactor (1), the pipe coil (2) with circulating pump (8), the catalyst (31), the blower (4) and the fuel supply (5). <IMAGE>
Patent DE-3902696-A1 (DE)
Title: Presentation device
Inventor: BEATTY PAUL HANLON JAMES
IPC: H01J31/20
Filed: 1989-01-30
Abstract: The invention relates to a presentation device for a plurality of colours, such as e.g. a cathode ray tube, having red, green and blue phosphor strips which are arranged in triplets, each of which forms a colour pixel (picture element) in the line-scanning direction, at least the red and green phosphor strips being coated with an electrically insulating barrier layer on which a thin film of blue-emitting phosphor is formed. When presenting colours, the ray energy is sufficient to penetrate the barrier layer and excite the main-strip phosphor in order to obtain the desired colour emission, the blue phosphor also being excited, the blue emissions, however, being perceived at a lower brightness than the red ones and therefore not reducing the perceived colour purity. In monochrome operation, the ray energy is reduced so that only the blue phosphor is excited. Since each strip is capable of emitting blue when it is excited, the image resolution in monochrome operation is increased from the dimensions of the colour triplet to the dimensions of the individual strip or better. The low level of the blue emissions is suitable and to be preferred for viewing infrared pictures at night, in particular by means of night-viewing goggles. Individual phosphor grains can obtain a skin of monochrome phosphor or they can be mixed with the main phosphor without a barrier layer, however, with ... Original abstract incomplete.

Patent DE-3905609-A1 (DE)
Title: Process for obtaining a microbial lipase
Inventor: VOIT HARALD DIPL ING
IPC: C12N9/20
Filed: 1989-02-23
Abstract: The intention is to find an improved process which makes it possible to produce a microbial lipase where possible without the use of antifoam agents and to discharge it at the highest possible concentration from the reactor in order to reduce the volume and the residence time in the subsequent workup stages, in order to reduce the investment and operating costs for the workup and in order to avoid losses of activity during workup. The process is characterised in that a microbial exolipase is produced in a reactor by supplying air. The reactor is operated for this purpose in such a way that there is deliberate formation of a foam in which the produced lipase is concentrated, while the lipase-poor fermentation broth with the microorganisms drains in the foam and is thus retained in the reactor. The lipase is harvested as foam fraction together with the air at the head of the reactor. The foam is separated into the concentrated liquid product and the product-free waste air only in a foam disintegrator downstream of the reactor. The apparatus volume and the residence time can be greatly reduced by carrying out the reaction and/or fractionating the foam in a centrifugal field. Lipases have great significance as catalysts for lipolysis in... Original abstract incomplete.

Title: Antilock hydraulic brake system
Inventor: BURGDORF JOCHEN DIPL ING
IPC: F16L55/05
Filed: 1989-03-21
Abstract: An antilock hydraulic brake system is proposed in which the pump (16) is connected to the brake line (12) by way of a pressure line (22). A damping chamber (24) and an orifice (27), by means of which the pressure waves occurring in a control sequence are to be smoothed, are arranged in the pressure line (22). This reduces the noise generated during a control sequence. The non-return valve (28) has the important function of preventing pressure medium from the brake master cylinder passing into the damping chamber (24) during uncontrolled braking. This system ensures that the noise generated during controlled braking is reduced without resulting in a longer pedal travel during uncontrolled braking. <IMAGE>

Patent DE-4007205-A1 (DE)
Inventor: SATO KOICHI
IPC: H04N9/83
Filed: 1990-03-07
Abstract: In a system in which different phase shift key data signals DPSK, relating for example to track number or indicating frame or field recording, are superimposed on video signals recorded on a magnetic disc, subsequent recovery thereof by band pass filter 26, rectification 32 and demodulation 36 may produce noise (stationary vertical lines) in the picture. Therefore the data signal is recovered and stored during the first reading of the composite signal while a mute signal is applied to an encoder receiving Y & C video signals from filters 22, 24. During subsequent readings the mute signal is removed and the data signal channel is disabled, e.g. by a switch prior to rectifier 32, or by disabling the latter. Disablement may be controlled by an external switch 40. <IMAGE>
