Patent NO-175997-C (NO)
Inventor: ANHAEUSER DIETER
IPC: B65D73/00
Filed: 1988-10-03
Abstract: The invention relates to a removal aid for mechanically detachable substrates adhering to a sheet-like, flexible carrier material and in the form of cuts or predetermined breaking lines in said carrier material. At least in the contact surface of the carrier material is provided for each substrate a separate, non-linear cutting or predetermined breaking line, so that when pressure is exerted on the carrier material with a force component in a direction at right angles to the substrate contact surface a carrier material portion with the substrate portion adhering thereto and bounded by the cutting or predetermined breaking line can be bent in the direction of the substrate or substrates, so that at least part of the substrate in the border area thereof adjacent to the cutting or predetermined breaking line is detached from the carrier material and consequently a gripping portion is formed on the substrate for the complete removal of the latter.

Title: Apparatus for dispensing comestibles
Inventor: GROME DONALD C
IPC: A21C11/18
Filed: 1990-01-12
Granted: 1994-05-17
Abstract: Abstract A battery-operated apparatus for dispensing comestibles has a housing to which a comestibles-receiving barrel is removably connected.  A removable piston is nonrotatably slidable within the barrel and pushed through the barrel by a piston rod nonrotatably connected to the piston and slidably received within the housing. The piston rod has external screw threads over a substantial encircling drive nut.  Drive means rotatably mounted in the housing and having a through-bore for slidably receiving the piston rod is provided for rotating the drive nut.  The piston rod and the drive nut constitute a reversible assembly so that, following use, the barrel and the piston may be removed from the housing for cleaning and the piston rod with the drive nut thereon may be removed from the housing, turned upside-down, and reinserted into the housing ready for another use.  Portions of the piston rod are unthreaded to prevent overtravel, and resilient stop members on the piston rod push the drive nut onto the threaded portion of the piston rod at each end of its travel to assure a threaded connection when the piston rod is reversed.

Title: Method and apparatus for steering casting belts of continuous metal-casting machines
Inventor: KAISER TIMOTHY D
IPC: B22D11/16
Filed: 1990-05-01
Granted: 2001-12-18
Abstract: A method and system achieving increased steering precision of flexible, metallic endless belts of continuous metal-casting machines. Such belts often have imperfections for example, low-carbon steel belts, generally have a "camber" curvature of their edges in their plane. Belts revolving in the machine normally are steered through sensing side-to-side position of one edge. The edge passes a sensor during every revolution of the belt. If the edge has camber, a prior art steering system continually will "hunt" in response to variations in side-to-side position of the cambered edge. This hunting causes repeated side-to-side belt motions, thereby inducing wear of belt coatings under edge dams, causing non-uniform heat transfer. Hunting also induces diagonal stresses and flutes in casting belts adversely affecting casting. The present sensor circuit following the "Cue" governs steering, thus eliminating or substantially reducing prior-art "hunting" steering problems.

Patent CA-2021514-C (CA)

IPC: G10L25/93

Granted: 1998-12-15
Abstract: In CELP coding, stochastic (noise-like) excitation is used in exciting a cascade of long-term and short-term all-pole linear synthesis filters. This approach is based on the observation that the ideal excitation, obtained by inverse-filtering the speech signal, can be modeled for simplicity as Gaussian white noise. Although such stochastic excitation resembles the ideal excitation in its global statistical properties, it contains a noisy component that is irrelevant to the synthesis process. This component introduces some roughness and noisiness in the synthesized speech. The present invention reduces this effect by adaptively controlling the level of the stochastic excitation. The proposed control mechanism links the stochastic excitation to the long-term predictor in such a way that the excitation level isinversely related to the efficiency of the predictor. As a result, during voiced sounds, the excitation level is considerably attenuated and the synthesis is mainly accomplished by exciting the short-term filter with the periodic output of the long-term filter. This reduces the noisiness, enhances the pitch structure of the synthesized speech and its perceptual quality.

Title: Process using virtual addressing in a non-privileged instruction to control the copying of a page of data in or between multiple media
Inventor: BLANDY GEOFFREY O
IPC: G06F12/10
Filed: 1990-08-31
Granted: 1995-08-15
Abstract: A single non-privileged instruction copies a page of data  from  a  source  virtual  address  to  a  destination virtual address, regardless of which of plural electronic storage media contain the page locations, and without the intervention of any supervisory program when media and virtual addressing have been previously determined for the locations of the subject pages.  The instruction is not required to specify which of the plural media it will use, does not require its user to know what backing media it will access, does not require main storage (MS) to be one of  its  backing  media,  and  allows  different  types  of physical addressing to be used by the different backing media.  The instruction can lock any page for use in an MP.  No physical direction of data movement is provided within the non-privileged machine instruction, which only designates virtual direction of movement.  The separation of virtual direction from physical direction is done by avoiding instruction control over selection of electronic media.   The non-privileged instruction can nevertheless express  a  preference  for  obtaining  a  copy  of  the destination page  in an electronic medium in which the content  of  the  page  can  be  processed  by  further instructions.  Also, the instruction can cause invocation of a privileged control program to avoid the need for a following condition code test instruction.  A privileged instruction is also provided to wait for the completion of the unprivileged instruction and to invalidate a non-MS medium page whether  it  is unlocked or  locked,  either correctly             or              incorrectly.

Granted: 2001-08-28
Abstract: A method for the manufacture of artificial teeth, either replacement of whole teeth or crowns, whereby a tooth is produced by machining from a layered block (20) of synthetic plastics materials, the layers (34, 36, 38, 40) being of predetermined carrying colour (hue), chro-ma, value and translucency to stimulate the pulp, den-tine and enamel layers in a real tooth, thereby providing an artificial tooth with the distribution and depth of co-lour of a real tooth. The process provides for varying the tooth colour by milling the tooth from a different section of the layered block to vary the thicknesses of the layers, at least at the labial, menial, distal and occlusal surfaces, so as to obtain a custom tooth matched very closely to a patient's real tooth colour and pattern. The invention permits the manufacture of an artificial tooth from mate-rials with a hardness closely matching that of a real tooth to provide similar wear properties.
