Patent DE-3802818-A1 (DE)
Title: Plastic pallet having an attachment frame formed from cardboard
Inventor: TEJTBAUER DIETER
IPC: B65D19/06
Filed: 1988-01-30
Abstract: In pallets of this type, the attachment frames made of cardboard are guided and connected by means of tabs which are fixed by their walls and on the pallet. In this case, the end faces of the attachment frame walls stand up on the upper deck of the pallet. In particular in the case of frequent storage in open air, the pallets are naturally exposed to the elements, the risk then existing that moisture, in particular rain water, will enter through the open, unprotected end faces of the cardboard, soften it and thus virtually destroy it. A similar weak point is formed by the wall openings through which bolts are inserted. Planned multiple use of the relevant cardboard is therefore very often impossible, which means that the costs for using the pallets are disproportionately high. According to the invention, provision is therefore made for at least two clamping devices (3) to be arranged in each case at least on two opposite sides of the upper deck (10). In this case, each clamping device (3) is guided longitudinally displaceably in curved paths (14) provided in webs (11) of the pallet. In the clamping position, the clamping devices (3) are supported on angled tabs (8) of the attachment frame (2) which rest on the upper deck. Since now no openings in the attachment frame are exposed directly to the elements, the usability is increased considerably, thus reducing the operating costs in total. <IMAGE>

Patent DE-3814561-A1 (DE)
Inventor: HARTMANN UWE
IPC: H03K4/06
Filed: 1988-04-29
Abstract: Such voltages are frequently necessary for generating correction currents which have to have the same phase as the fundamental wave of another voltage. The use of a filter circuit or synchronised oscillator circuit is known but this requires a calibration to the fundamental wave. In Patent Application P 37 01 927.9, a method for generating these voltages is described. It has been found that when this voltage is applied to the correction of gull-wing geometric distortions on the display screen of a picture tube, errors occur at the top and bottom screen edge which are opposite to the subsequent or prior parts of the displayed raster. 
<??>The invention compensates for these errors in that the correction current is inverted in the vicinity of the top and bottom screen edge so that its zero transitions do not coincide with the top and bottom screen edge. 
<??>Generation of a correction current for the vertical deflection in television receivers.

Title: DeNOx plate catalyst and process for the production thereof
Inventor: GAJEWSKI WOLFGANG DR
IPC: B01J37/02
Filed: 1988-08-01
Abstract: In a DeNOx plate catalyst, there is the problem of joining the catalytically active substances, in particular titanium oxide, vanadium pentoxide and tungsten trioxide, in a suitable manner and sufficiently abrasion-resistant amongst each other and to the support metal sheet (expanded metal sheet, sieve structure), in order to withstand for sufficiently long the abrasive wear of the ash particles entrained in the flue gas stream. For this purpose the invention provides that the catalytically active substances are joined together by a binder system on a support metal sheet which had previously been flame-sprayed with aluminium and in which the binder system contains phosphorus, carbon, zirconium oxide, zinc oxide and/or nickel oxide. Furthermore, the catalytically active substances can additionally be joined by 1 to 5% by weight of aluminium silicate fibres and/or aluminium oxide fibres. The invention can be used in plate catalysts used in the flue gas stream, in particular DeNOx plate catalysts. <IMAGE>

Patent DE-3840020-A1 (DE)
Title: Radial die rolling machine
Inventor: GROENE SIEGFRIED ING GRAD
IPC: B21H1/06
Filed: 1988-11-26
Abstract: The invention relates to a radial die rolling machine in which the rolling pass is formed by a radially acting die ring on the outside, a radially acting, fixed and non-displaceable mandrel roll which plunges into the workpiece from below, an axially acting mandrel-roll plate which closes off the rolling pass from below, and an axially acting taper roll which delimits the rolling pass from above and can be swung away radially and axially. The rolling plane slopes. Loading and unloading is considerably easier. Since the rolling plane, guide, pass mounting and feed cylinder are mounted in one plane, an optimum radial die stiffness is obtained. Since the workpiece ejector and the mandrel-roll mounting are arranged on one side, namely underneath the workpiece, the mandrel roll can be of fixed design and thus does not need to be moved for loading and unloading. This likewise increases rigidity in the rolling pass and reduces the number of adjustment axes required to one. The distance between the fixed mandrel roll and the receiving point for the workpiece blank is always the same. This allows the rolling machine to be loaded by means of a simple swivelling mechanism.

Patent DE-3907864-A1 (DE)
Title: Dental bracket
Inventor: GUENZEL HANS
IPC: A61C7/12
Filed: 1989-03-10
Abstract: The invention describes a dental bracket to be applied on the dental surface and having a retention base and two wings each of which is provided with a rectangular slot for accommodation of a dental arch wire. The slots are inclined relative to the retention base in order to be able to execute a corresponding torque upon the tooth. This inclination is achieved by a correspondingly oblique position of the retention base relative to the bracket wings. Furthermore, the slots are inclined relative to the lateral surfaces of the wings in such a way that a corresponding tilting moment (angulation) can be exerted upon the tooth. The periphery of the retention base is designed in rhombus shape such that the upper and lower peripheral edges of the retention base extend in parallel to the slots. The retention base and the two bracket wings are made in one piece. Moreover, the basic surface of the retention base is provided with an axial and circumferential knurl. These measures permit the dimensions of the dental bracket to be kept very small. <IMAGE>
