Title: Process, coder and decoder for digital transmission and/or recording of component-coded colour-tv signals
Inventor: SCHWEIDLER SIEGFRIED
IPC: H04N19/98
Filed: 1991-09-06
Abstract: A digital transmission and/or recording system for component-coded colour-TV  signals. At present, no professional video recorders are available which can record progressive 16:9-format 625-line TV  images. Digital studio video recorders operating by the D1 process can only record the YUV components of interlaced 4:3-format 625-line images. By means of vertical sub-scanning of the UV-components and subsequent block companding using special encoding techniques within 8-byte blocks (40), the neces-sary memory capacity is made available for recording progressive 16:9-format 625-line TV images. The invention is of particular application to the digital recording of progressive 16:9-format 625-line TV  signals using PCM video recorders.

Title: Hitching device for industrial vehicle
Inventor: OSKAM JOHN
IPC: B66F9/18
Filed: 1993-03-12
Abstract: ABSTRACT OF THE DISCLOSURE         The hitching device of the present invention is adapted to connect an industrial vehicle to a load-carrying trailer to permit the vehicle to manoevre the load-carrying trailer.  The industrial vehicle is of the type having a pair of forks which are substantially parallel to each other.  The hitching device comprises a frame which is connectable to the load-carrying trailer by a connector.  First and second bars are disposed on the frame remote from the connector.  These bars lie substantially parallel to each other and substantially at right angles to the direction of travel of the forks of the vehicle.  The bars are vertically and horizontally spaced from each other so that a gap is formed between them for receiving the forks.  The second bar is disposed so that it lies vertically below the first bar, and so that it extends horizontally further from the connector than does the first bar when the forks are raised by the vehicle to a position which enables the vehicle to push or pull the load-carrying trailer.  The configuration of the second bar substantially prevents the forks from being horizontally withdrawn from the hitching device until the forks are lowered by the vehicle.  In this position, the industrial vehicle can pull the load-carrying trailer.

Title: Tiltable supporting roller bearing
Inventor: AUF DEM VENNE JOHANNES
IPC: F27B7/22
Filed: 1993-04-01
Abstract: Abstract The invention relates to a tiltable supporting roller bear-ing for supporting a rotary drum and comprises a supporting roller which is mounted so as to be freely rotatable as well as a bearing structure for the supporting roller which is supported with respect to a stationary supporting sur-face by a four-membered linkage, the two rockers of which are arranged in such  way that the point of rotation of the linkage lies in the region of the intersection of the line of contact between the supporting roller and the riding ring with the vertical central axis of the supporting roller.  This construction makes it possible to compensate for skewing of the rotary drum riding ring and at the same time to make a marked reduction in or largely to avoid undesirable axial forces resulting from additional longitu-dinal movements of the rotary drum.

Sides of the hexagon have side lengths such that the lengths vary by no more than 1 D from each other.   Strands,  internally within the package, i.e. which would not have an exteriorly exposed surface if all package wraps were removed, contact six adjacent strands.    The package usually consists essentially of, n rows of strands and an external package retainer, usually a package wrap.          Preferably each of the lines forming the hexagon passes through the central axes of either an equal number of strands or a number of strands which do not vary by more than one.  Preferably, the package according to the present invention has an odd number of rows n, which is a number of 5 to 15 and the number of strands is other than 50.

IPC: F28F13/00
Filed: 1992-04-14
Abstract: A high temperature fluid-to-fluid heat exchanger (10) is described wherein heat is transferred from a higher temperature fluid flow core region (75) to a lower temperature fluid flow annulus (50).  The wall (54) separating the high and low temperature fluid flow regions is comprised of a material having high thermal absorptivity, conductivity and emissivity to provide a high rate of heat transfer between the two regions.
