Title: Recording process using thermal imaging - with recording material whose contact angle is  reduced by heating and liq. ink which adheres to selectively heated areas
Inventor: KATANO YASUO
IPC: B41M5/36
Filed: 1990-03-30
Abstract: Recording process comprising (a) and (b) in either order: (a) contacting a contact material (I) with the surface of a recording material (II) having surface characteristics such that the retrogressive contact angle is small when the (II) is contacted with a liq. and is in the heated state, the (I) being chosen from a liq. or vapour or a solid which under temp.  conditions below the temp/ at hwich the angle of the (II) begins to become smaller, forms a vapour or a liq. or changes into one of these,a nd (b) selectively heating the surface of the recording material (II) corresponding to image information so latent image is formed on the surface of the (II) where the prevailing retrogressive contact angle corresponds to the temp.  of the (II) obtd. by the selective imagewise heating. USE/ADVANTAGE - Simple imaging method which uses imaging materials in which a latentt image can be induced by using property the the retrogressive contact angle of the surface is smaller when the surface is contacted with a hot fluid. A recording medium contg. a colourant may be  applied to the surface carrying the latent image to develop the latent image. The developed image may be fixed on the surface of the recording material, or the developed image may be transferred to another substrate and fixed there. After the contact material has been removed from the surface of the recording material, the material may be heated overall to erase the  image. The imaging method is simpler w.r.t. appts. than previous imaging systems and allows the construction of compact appts.

Title: Hardened material shaping - uses lower forces during heating than levels for elastic or plastic distortion to allow major shape and size changes
Inventor: VETTER JOCHEN ING GRAD
IPC: C21D8/00
Filed: 1990-06-09
Abstract: To change the shape and dimensions of material which has been quenched and tempered, case hardened or pptn. hardened, the amt. of force applied during heating is below the value which would be needed to bring the workpiece into the required shape and size through elastic and/or plastic distortion. Before or while stresses are applied to the workpiece, the forces imposed on it pref. apply only an elastic distortion to bring it into the required shape and dimension, which is less than 50% of the shaping force calculated for the tempering and drawing temp. Through the process, a component is stretched or compressed above or below its size, before heat treatment, and different forces are applied to various sections of the component in terms of value and direction. The workpiece is subjected to forces to bring it into the required contour during the tempering and drawing process. ADVANTAGE - The technique allows a workpiece to be given a major change in shape and size.

Title: Breast roller vibration mechanism - has a hydrostatic buffer between the oscillator and roller journal to reduce bearing wear
Inventor: WANKE WILHELM
IPC: D21F1/20
Filed: 1990-10-09
Abstract: In the mechanism to vibrate the breast roller, or similar roller, in a papermaking machine, a hydrostatic oscillation transmission system is between the oscillator and the journal of the roller. Pref. the oscillation transmission acts directly on an extended roller journal or with a journal flange or pressure plate bonded to it, with the system coupled to one of the journals of the roller. The pressure plate is aligned generally radially to the rotating axis of the roller, keyed to the journals, and surrounded by a pressure housing filled with a hydraulic fluid. Each axial surface of the pressure plate has at least one ring zone in the peripheral direction round the roller axis in the presure housing or in the pressure plate, and each end side of the pressure plate has at least one ring zone passing round separated radially inwards and outwards through ring gaps from radially inner and outer pressure zones. At least one connection for hydraulic pressure fluid is at least at one of the radially inner ring zones, while at least one pressure feed channel with a throttled narrowing is near the ring zone passing round. The outflow for the hydraulic pressure fluid is at the radially outermost ring zone of the presure housing. The pressing housing has at least one inflow and one outflow for the feed and exhaust of the hydraulic pressure fluid. The centre axis of the push journal, aligned directly or closely with the roller axis, is positioned by a bearing pedestal between the pressure housing and the oscillator, together with radial locking against rotation. The oscillator is a mechanical system with unbalances. USE/ADVANTAGE - The vibration of the breast roller is induced during the mfg. of wood-free papers. The transmission system reduces the axial stresses on the roller bearings, to increase their working life.

Title: Method of lowering railway track where it is above required level - involves first removing ballast between sleepers and subsequently removing remainder from under them
Inventor: KNAPE FRITZ
IPC: E01B27/04
Filed: 1991-01-18

Title: Release method for overcurrent protection switch - using measured current values and corresponding current gradients obtained by differentiation to trigger switch
Inventor: BERTHOLD RAINER DIPL ING
IPC: H02H3/08
Filed: 1991-04-11
Abstract: The release system measures the current in each main current path (R, S, T) at regular intervals e.g. via respective current sensors (10, 11, 12) and differentiates the obtained current values to determine the corresponding current gradients. The momentary current and current gradient values are paired together and compared with a given threshold value function, when a defined range is exceded. Alternatively, the momentary current gradients for each measured current value are summated and a release signal for the overcurrent protection switch is supplied when the obtained sum differs from zero. USE - For protecting multi-phase supply or electric motors.

Title: Hydraulically damped tension element - has reaction face on cylinder bush to avoid extra safety pressure valve
Inventor: RUEDIGER ECKHART
IPC: F16F9/512
Filed: 1991-07-24
