Title: Apparatus for the continuous application of a minimal quantity of a liquid onto a material web
IPC: B05C1/14
Filed: 1993-04-29
Abstract: It is an advantage in technological terms if a textile material can be provided with a small quantity of a liquid uniformly over the working width. It is necessary, at the same time, to ensure that this liquid, without forming droplets, wets the textile material in a minimal layer, for example a printed material web before steaming. For this purpose, there is proposed an apparatus, in which a continuously washable endless band receives the liquid, carries it to the textile material and transfers it to the latter. For this purpose, the endless band is arranged so as to run obliquely upwards in the transfer region. The top side of the endless band is to be provided with the liquid to be transferred, and the endless band then carries the layer of liquid immediately thereafter to the textile material which is assigned in parallel to the driven endless band. The surface design, material and obliquity of the endless band are parameters for influencing the thickness of the liquid layer to be transferred. <IMAGE>

Patent DE-4328598-A1 (DE)
Title: Rolling element
Inventor: YOSHIZUKA NORIYOSHI
IPC: C21D9/36
Filed: 1993-08-25
Abstract: Rolling element which has better strength and allows the formation of oil films between its rolling surface and its mating surface and has a long service life even under unfavourable lubrication conditions. During nitriding, the workpiece is subjected to a heat treatment. The workpiece is then treated in order to form minute depressions in its surface so that such a surface has a surface-roughness parameter RMS of no less than 0.10  mu m and a negative SK value. This increases the surface strength of the rolling element and improves the oil-film formation rate. It is less likely that the surface of the rolling element will suffer damage due to flaking. Its service life is extended.

Patent DE-4337554-A1 (DE)
Inventor: PALMATIER ROLAND T
IPC: B41F13/10
Filed: 1993-11-04
Abstract: In an offset perfector of the kind in which a web of printstock passes between two adjacent blanket cylinders, and of the kind in which each blanket cylinder has a respective associated plate cylinder, and of the kind wherein all four cylinders have substantially parallel axes contained in a common plane, flexural and torsional vibrations resulting from gutter crash are obviated by eliminating (or substantially eliminating) the gutters which cause the vibrations. Thus, as described, the blanket cylinders are fitted with seamless-sleeve blankets, and the plate cylinders are filled either with seamless-sleeve printing plates or by plates so filled that the gutter is effectively less than 80 thousandths of an inch wide. The blanket cylinders preferably comprise rubber blanket layers supported on expansible nickel sleeves. Access to the ends of "in situ" cylinders to enable "on-press" exchange of interference-fit seamless blanket or printing sleeves is via "door-like" closures in the machine frame, which closures releasably engage the cylinder-end bearing. Compressed air fed to peripheral apertures in the cylinder creates an air-cushion which expands the sleeves during the exchange. The consequent reduction in vibration and bearing loading allows the following improvements in machine construction:   (a) elimination of direct running contact between adjacent cylinders via dedicated "bearer" surfaces. (b) adoption of equal sized printing and blanket cylinders, thereby enabling a reduction of torsional oscillations by adoption of simplified machine drives wherein a drive shaft (210 or 226) directly drives a blanket cylinder via a 1:1 bevel gear (212 or 228), and the other cylinders are driven by 1:1 gearing directly meshing with neighbouring cylinders. Separate parts of a press may be driven in synchronism by independent motors from a single control point, thereby further reducing torsional vibrations due to a long drive shaft.   The consequent reduction of both flexural and torsional vibrations is stated to enable the machine to run at up to 3500 ft per minute before generating vibrations at the resonant frequency of the overall machine structure.

Title: Semiconductor component
Inventor: HOSHI MASAKATSU
IPC: H02P7/29
Filed: 1994-02-21
Abstract: A semiconductor component with a voltage surge input detection circuit is provided with a driver circuit, for example for a reversible motor. To protect the power transistors which form the power driver circuit against destructive breakdowns when the voltage surge input detection circuit detects the voltage surge which is input via the driver circuit and exceeds a predetermined voltage, namely the maximum permissible power supply voltage of the power driver circuit, the voltage surge input detection circuit outputs the signal in order to turn off the MOS power transistors. These circuit elements are manufactured integrally on a semiconductor chip. The voltage surge input detection circuit detects such a voltage surge which is input by a power supply connection, either via the voltage, the current or the temperature rise in the semiconductor chip. The breakdown voltage per power transistor can be half the maximum permissible power supply voltage. In addition, the voltage surge input detection circuit and these MOS power transistors are manufactured on the same semiconductor chip.

Title: Printing method without printing formes
Inventor: SCHANDELMAIER MICHAEL
IPC: B41J2/447
Filed: 1994-08-05
Abstract: It is known to use printing methods with printing formes to achieve the printed product by means of the print. The production of these printing formes always requires time and material outlay. The technical alternative is to use methods without printing formes, which achieve the printed product by electrostatic means (copiers, laser printers) or by means of ink jet directly from the latent subject. These methods without printing formes are too slow compared to the conventional printing techniques in the case of a relatively high number of copies. A rotating, transparent roller is coated on its surface with an n-doped and p-doped semiconductor in such a way that charging zones are produced on its surface under incident light, at the point of the incident light. While the roller rotates, the outer ceramic surface provided with wells is filled with ionised printing ink by means of chamber-type doctors. The arrangement of the doping of the semiconductor and the ionisation of the printing ink must be such that the charging of the printing ink and of the charging zone next to the outer surface of the well is of the same sign. As a result, the printing ink is rejected by the roller under incident light from above. The ink droplets jump off the roller onto an offset cylinder or the printing carrier. This effect is enhanced by a charge carrier with a charge of opposite sign relative to the ionised printing ink and the outer charging zone, which charge carrier is located in the offset cylinder or behind the printing carrier moving past the ductor...
