Patent DE-3835805-A1 (DE)
Title: Suppression of the radar reflection from surfaces, especially from aircraft
Inventor: HORA HEINRICH PROF DR DR
IPC: H01Q17/00
Filed: 1988-10-21
Abstract: A method and an arrangement are described covering how coatings of materials over the surfaces of aircraft parts reduce the reflection of electromagnetic waves in the wavelength band from 0.01 to 100 cm (radar) to values considerably less than 1%. A method is used in this case, in which the conventional dielectric properties of the coating materials are compensated for by plasma-like properties, it being possible to produce the latter by suitable irradiation of hard electromagnetic particle radiation.
Patent DE-3905672-A1 (DE)
Inventor: LOHRMANN HORST DR ING
IPC: C03C11/00
Filed: 1989-02-24
Abstract: In a process for the production of mouldings, in particular building boards, from blown glass in which a mixture of comminuted glass and a blowing agent is heated on a substrate to generate a blowing and melting operation and the mixture is then cooled to form the moulding, the most uniform possible pore diameter, high porosity, high physical water vapour permeability and thus low water vapour diffusion resistance, and low bulk density of the resultant moulding are achieved by proceeding as follows: ground glass having a particle fineness of less than 0.250 mm, with a proportion of from 45 to 80 % by weight having a particle fineness of less than 0.040 mm, and the blowing agent are firstly mixed. Blanks having a size of from 1 to 30 mm are then produced from this mixture with shaping, still without the action of heat. These blanks are applied, as at least one layer, to the heated substrate at mutual free separations sufficient for their enlargement in volume, and are blown under the action of heat at from 750 to 1000 DEG C so that a coherent moulding is formed.

Patent DE-3909057-A1 (DE)
Inventor: VENTURINI GIANCARLO
IPC: B62D1/12
Filed: 1989-03-18
Abstract: A progressively controlled hydraulic steering device, in particular for vehicles for the disabled comprises a hydraulic distribution assembly which carries internally a small shaft (13) having a free rotation of about 6 DEG  in one direction or in the other one and ending in an elongated cylindrical member (12). The assembly is enclosed within an enclosure (1) having holes (2) for connection to the oil pump-reservoir circuit (3, 4, 5, 6) as well as to the two chambers of the hydraulic actuating cylinder (9). A lever (16) is connected to the distribution assembly and hence to the cylindrical member crank (21) at one of its ends. The lever is capable of rotating through about 45 DEG , the progression of travel after the first 6 DEG  of the movement, being dependent on the actuation of the steering gear. The connection of the crank (21) to the actuating cylinder (9) limits movement of the lever (16) to the degree of rotation imparted to the road wheels at a given time. <IMAGE>

Title: Internal tank pump, especially a fuel pump for a motor vehicle
Inventor: BANHOLZER DETLEF DIPL ING
IPC: B60K15/077
Filed: 1989-06-21
Abstract: In order to a large extent to avoid the transmission of vibration from a liquid pump (1) arranged in a tank to the tank bottom (3) on which it is held, a rubber-metal bearing arrangement (12) is arranged between the pump casing (4) and a pump mounting (6) which allows the pump arrangement to be locked or unlocked in the manner of a bayonet catch by rotation of the pump casing (4) relative to the tank bottom (3). This rubber-metal bearing arrangement (12) has stops (16, 17, 18, 19) on its metal connection parts (11, 13) which come into effect in the circumferential direction only during mounting and removal operations or, after the destruction of the rubber body (15) of the mounting arrangement (12), to prevent the detachment of the pump casing (4) from the tank bottom (3) (Figure 1). <IMAGE>
Patent DE-3927198-A1 (DE)
Title: Restriction of spread of fire - involves material which turns to foam when heated to block space under sloping roof
Inventor: ROTH HEINRICH WILHELM
IPC: E04B1/94
Filed: 1989-08-17
Abstract: The building with a sloping roof has panels (5) of thermal insulation fitted between the rafters (3). A channel (6, 7) is thus formed between the insulation (5) and the undersides of the tiles. In the event of a fire this channel (6, 7) would act as a chimney and cause the fire to spread more quickly. The spread of fire is restricted by fitting a strip of plastics (8) in the channel (6, 7) dividing it into two channels (6, 7). A material which turns into a foam when subjected to heat is attached to the edges of the strip (8). The foam produced by this material obstructs the flow of air in the channels (6, 7) and so restricts the spread of the fire. USE/ADVANTAGE - Reduction of fire risk by using foaming material to fill up space under sloping roof.
Patent DE-3935013-A1 (DE)
Title: Corona discharge system - uses inks or coatings which release no flammable vapours in ozone-free operation
Inventor: KALWAR KLAUS
IPC: B29C59/10
Filed: 1989-10-20
Abstract: Applying corona treatment to (un)coated materials, e.g. to bond varnish, colour or an adhesive, the varnish or ink or adhesive are free of solvents which could ignite on release. The corona discharge is near the application roller for the substrate or near the paired lamination rollers. Outside their working position, the corona electrodes are held at a working temp. to give them ozone-free operation, heated, and returned to the working position.  Pref. a corona discharge is applied directly after a coating has . been applied to the carrier, to dry it, and the application or laminating roller is used as one of the electrode pairs to generate a corona discharge. The web is subjected to a corona  discharge before and after a substrate has been applied using a pressure or counter-pressure roller as one of the electrodes. Part of the heat generated at the corona electrode is transferred to the material by blowing on the electrode. ADVANTAGE - System prevents ozone development at the corona electrodes to improve their efficiency, and gives a small and compact assembly.
