Patent DE-3822723-A1 (DE)
Title: Bed for immobile patients
Inventor: RUF HERMANN
IPC: A61G7/008
Filed: 1988-07-05
Abstract: The invention relates to a pivotable bed for immobile patients whose frame comprises pivotable cam discs, especially in the form of circular segments. The drive for pivoting the latter is effected by means of a deformable member connected to and guided by the cams or segments, preferably a chain, which extends over and is driven by a group of, preferably three, wheels or rollers. The discs or segments not only effect the drive but also their support and guidance by engagement of supports via corresponding intermediate members. The drive ensures shock-free and reliable pivoting coupled with a compact, simple and largely maintenance-free construction (Fig. 2). <IMAGE>

Title: Pressure plate bearing for materials testing machines
Inventor: GLATT PETER
IPC: G01N3/04
Filed: 1988-08-26
Abstract: In a pressure plate bearing (1) for materials testing machines, consisting of a spherical shell (12) fastened onto a receiving plate (11) and a spherical cup (13) installed in this so as to have limited adjustment, on which a pressure plate (14) acting on a sample body (10) is mounted, the spherical shell (12) and/or spherical cup (13) are provided, in the region of the vertex, with a free space (31) which is connected via one or more delivery channels (35) to a supply space (40) containing a lubricating liquid (40) and is connected to the atmosphere via a deaeration channel (36). By means of this design it is guaranteed that the spherical cup (13) is easy to adjust in the unloaded condition and free play is possible on the surface of the test body (10) in the case of contact but, however, since the lubricating liquid (40) is pressed out of the gap (15) between the spherical shell (12) and the spherical cup (13) in the case of overshooting a limiting value loading, automatic locking occurs. The pressure plate bearing (1) thus corresponds to the standard currently in force for pressure testing machines which are used for the testing of non-metallic-inorganic construction materials. <IMAGE>

Inventor: STEINER MORITZ
IPC: A47B96/06
Filed: 1988-09-02
Abstract: The side plate according to the invention is intended to be fixed on a broad side surface of a bracket used with suspended filing racks. It is fitted with catch tongues (30, 32), projecting over the plane of the plate on one side to receive a suspension rod (38). In order to be able to plug the side plate (10) onto the bracket, it has at its top edge in the region of the open-edge recess (24) a hooked bent part (44) which engages behind one of the two flat material rods (16', 16") of the bracket (16) in the region of the top edge inside the open-edge recess (22). Two further simple bent parts (46, 48) rest in the plugged-on state against the top edge in the region of the open-edge recess (22). Furthermore, the side plate contains a lower bent part (52) which engages under the bottom edge of the flat material rod (16', 16"). The locking on the flat material rod is effected with the aid of a strap (56), which is connected to the side plate (10) via a narrow material bridge (58) and can be bent out of the plane of the plate with deformation of the material bridge (58) in such a way that the top edge (60) of the strap engages below the bottom side edge of the flat material rod (16', 16"). <IMAGE>

Abstract: PCT No. PCT/EP89/01198 Sec. 371 Date Apr. 19, 1991 Sec. 102(e) Date Apr. 19, 1991 PCT Filed Oct. 11, 1989 PCT Pub. No. WO90/04906 PCT Pub. Date May 3, 1990.A system for adaptively separating luminance and chrominance components of a color television signal includes a chrominance comb filter comprising a delay network with dual delay elements for providing a combed chrominance component, a bandpass filter for providing a bandpassed chrominance component, and a subtraction circuit. The subtraction circuit subtracts either the combed chrominance component or the bandpassed chrominance component from the television signal to produce a separated luminance component as a function of the phase of signals obtained from the delay network. Illustratively, the subtracter subtracts the bandpassed chrominance component from the television signal in the presence of color transitions in the vertical direction, and in the presence of 180 DEG  color transitions.

Title: Process for reducing the nitrogen oxide content in the offgas from glass furnaces
Inventor: PIEPER HELMUT DIPL ING
IPC: C03B5/235
Filed: 1988-10-28
Abstract: In glass furnaces, the high temperatures that are necessary cause the production of nitrogen oxide, which either must be disposed of at great expense or represents environmental pollution. The object of the invention is to reduce the NOx content in the offgas from glass furnaces. This object can be achieved according to the invention in furnaces in which the offgas is passed over the glass batch in countercurrent and cools, heating the glass batch, by adding an NH3-liberating solid, for example ammonium salts, to the glass batch. The invention is employed in furnaces which have a zone in the batch melting region with an offgas temperature of 850-1000@C at a batch temperature of 500-600@C. <IMAGE>

Patent DE-3900226-A1 (DE)
Title: Floodlights
Inventor: BEURICH HOLGER DR ING
IPC: F21V17/10
Filed: 1989-01-05
Abstract: In the case of floodlights it is common to provide on the side of the light emission opening a light-transparent screen which closes said opening, is fastened to the housing so that it can be folded up and bears on the support on the housing side, in the state in which it closes the housing, via a sealing which is annularly closed and protects the inside of the housing from atmospheric influences. In the case of high requirements in terms of protection from atmospheric influences a contact pressure which is as uniform as possible has to be ensured on the screen over the circumference of the sealing, requiring relatively complex closure devices. To create a remedy therefor, it is proposed to use angular hooks (1, 3) on the housing side and plates (3, 1) on the screen side with suspension openings (3, 11) for suspending the screen (3) in an articulated manner and to provide closing springs (3, 2) formed from spring band only on that side of the screen which is opposite the plates, which closing springs engage, in a locking manner, with their locking studs (3, 24) behind an angular strip (1, 11) on the housing side when the screen is folded up. <IMAGE>

Title: Fuel injection pump for IC-engine - has spring-loaded pistons which delay start of main fuel flow to injection nozzle
Inventor: HOEFKEN WILFRIED DR
IPC: F02M45/06
Filed: 1990-06-09
Abstract: The fuel injection pump for an ic-engine has a piston (2) which operates in a cylinder which is supplied with fuel through ports (4a, 4b) which connect the cylinder to an annular chamber (5) which receives fuel from the main pump. As the piston moves upwards the increasing pressure of the fuel acts on the primary injection piston which pumps fuel to the injection nozzle through the passageway (13).When this primary piston (11) abuts against the stop (12) the fuel pressure acts on the delay piston (19) through the passageway (17) and compresses the spring (22) so that the main supply of fuel flows out through the non-return valve (26).
