Patent EP-0259062-A3 (EP)
Title: Corrugated packing
IPC: B01D53/18
Filed: 1987-08-19
Abstract: Disclosed is a technique for packing an exchange chamber to facilitate interaction between two fluids. Corrugated packing plates are arranged with the corrugations of next corrugated plates running in different directions. The plates feature slots breaking the ridges of the plates and having corresponding tabs projecting into the corrugation grooves. The slots may provide drip points for liquid as one fluid moving through the slots in addition to permitting flow of the second fluid through the slots. A lip at the intersection of a slot and the ridge it breaks captures liquid bridging the slot to direct such liquid to the underside of the ridge.

Abstract: Zur Erleichterung der Herstellung und zur Verringerung des 
Gewichts einer Tragrolle aus einem etwa hohlzylindrischen 
Rollenkörper und jeweils zentrisch in dessen beiden axialen 
Stirnenden festgelegten Wälzlager wird der Rollenkörper aus 
Kunststoffmaterial hergestellt. Dazu werden zunächst auf 
einem Formdorn die beiden im Abstand angeordneten Wälzlager 
und der dazwischenliegende Teil des Formdorns mit einem 
thermoplastischem Material in geeigneter Dicke umhüllt. 
Nach Entfernen des Formdorns wird dieser Rohling in eine Blas­
form mit der gewünschten Innenkontur der fertigen Tragrolle 
eingebracht und es wird nach erneutem Plastifizieren des 
Kunststoffs durch den vom Formdorn gebildeten Kanal ein 
Druckgas eingeblasen, so daß sich das Kunststoffmaterial an 
den Formhohlraum der Blasform anschmiegt und dadurch die 
fertige Tragrolle gebildet wird.

Title: Method and device of the discharge of fine grained and hot solids
IPC: B01D47/00
Filed: 1988-03-10
Abstract: For discharging fine-grained hot solids from a pressurised space (1, 3, 4, 5, 9), the solids are continuously fed by means of a carrier gas to a washer (8), which is at a differential pressure relative to the space (1, 3, 4, 5, 9).

Abstract: According to this invention, in a display system 
having a CRT controller for arbitrarily and selectively 
display-driving a plasma display (23) and a CRT display 
(25), display fonts inherent to the displays are pre­
pared, and a display font corresponding to the display 
is selectively used and displayed in accordance with a 
display to be display-driven. The fonts include a 
plurality of types of graphics and text fonts, and are 
selectively used. As the text font, a single font and a 
double font are selectively used. When a display mode 
of the plasma display having a ratio of the number of 
dots in the vertical direction to that in the horizontal 
direction different from that of the CRT display is set, 
a specific raster of the display screen is scanned twice 
to stretch an image.

Title: Method and/or apparatus for demodulating a biphase signal
IPC: H03M5/12
Filed: 1988-08-18
Abstract: The invention relates to a method and/or a device for demodulating a binary coded phase-modulated signal (biphase signal). It is provided to determine the period of time (T) passing between each two successive level jumps of an incoming biphase signal, to generate or extract a clock frequency (B) approximately corresponding to the bit rate of the biphase signal with the aid of a clock generator, the clock period (1/B) of which clock frequency is compared with the period of time (T) between each two level jumps, and to determine the logical value of the biphase signal with the aid of an interrogating circuit controlled by the clock frequency (B), and to output a signal corresponding to the logical value, whenever a value of between 1/4 and 3/4 of 1/B was determined twice in succession for the period of time (T) immediately before, or whenever a value of between 3/4 and 5/4 of 1/B has been determined for the period of time (T) immediately before. In addition, a signal identifying a disturbance can be output or the output can be muted if a value of less than 1/4 of 1/B or greater than 5/4 of 1/B has been determined as the period of time (T). The invention makes it possible to recover the original data with sufficient reliability in a relatively simple manner when a biphase signal is present.

Title: Studded footwear
IPC: A43C15/16
Filed: 1988-03-08
Abstract: An internally screw-threaded socket (1) for incorporation in an article of footwear, such as a golf shoe, is provided on its outer surface with teeth (5). A stud for use with the socket includes a flange (12) and an externally screw-threaded spigot which projects upwards from the flange and can be screwed into the socket. Teeth (14) on the stud, spaced outwards from the spigot, interengage the teeth on the socket when the spigot is screwed into the socket and prevent the stud being freely unscrewed. The teeth on the stud and socket may be ratchet-shaped so as to make it easier to screw the stud to the socket than to unscrew it from the socket. The teeth on the stud are preferably frangible so that at least some of them break off when the stud is unscrewed for replacement. The teeth may be so spaced and located that, irrespective of the relative rotational positions of the stud and socket, at least some of the teeth on the stud are free to assume their natural shape rather than being deformed by contact with the teeth on the socket.

The front cover (60) is processed by any suitable home 
or office copier, embossing, foil stamping, colour 
printing or like machine capable of custom processing a 
single sheet of ordinary document size. The processed 
cover (60) is then attached to the attaching flange by 
means of the pressure sensitive adhesive (52,54,56). 
Document pages are stacked and inserted against the 
glue strips of the spine, and the glue is heated to 
secure the document pages and provide a complete bound 
document having the selectively processed front cover. 
There is also disclosed a method of binding a document 
using the binder described.

utilizing the steps of selecting a flexible, porous, 
bioabsorbable tube device and, then, suturing the nerve 
ends within the tube device such that a predetermined 
gap is left between the proximal and distal nerve ends 
to allow for nerve axon growth across the nerve gap 
from the proximal nerve end to the distal nerve end.

Title: Functionally modifiable cable television converter system
IPC: H04N7/16
Filed: 1990-04-12
Abstract: A cable television converter with remotely modifiable functionality receives firmware downloaded over a cable television network. The integrity of the firmware is verified, and if valid, the firmware is executed to provide one or more converter functions. If the firmware is invalid, default operation software contained in ROM is executed instead of the firmware to return the converter to baseline operation. In one embodiment, the converter includes a frequency agile data receiver to receive control instructions on a first data channel and firmware on a second data channel. The receiver is forced back to the first channel if a successful firmware download does not occur on the second channel within a predetermined time period. The firmware is continuously transmitted in short segments, and the converter can continue to receive segments until all the segments of a designated firmware package have been successfully downloaded, unless the predetermined time limit expires sooner. <IMAGE>
