Patent CA-2121341-A1 (CA)
Inventor: WOLPERT WALDEMAR
IPC: B21B45/02
Filed: 1992-10-08
Abstract: The invention is directed to a hot-rolling process and a hot-rolling mill for metal strips (5) having one or more roll stands with work rolls (1, 2). In order to prevent surface defects on the work rolls (1, 2), a coolant liquid is sprayed on the entry side in a narrow region extending immediately in front of the roll gap exclusively by a series of flat jet nozzles in such a way that their core jets primarily strike the surface of the work rolls or are directed into the roll gap for direct cooling and in that the entering metal strip is acted upon at the same time by the same coolant liquid for protecting the surfaces of the rolls from the radiated heat of the metal strip. The spraying of the coolant liquid is regulated in such a way that the metal strip is cooled only in a very narrow outer zone. In so doing, the temperature at the surface of the work rolls (1, 2) is adjusted in such a way that it lies below the boiling point of the coolant liquid at least immediately in front of the roll gap.

Filed: 1994-07-11
Abstract: The object of the present invention is to prepare a calcium hydrogen phosphate that has excellent binding properties, a large oil adsorption capacity and a specific surface area, and is therefore suitable as an excipient. A scale-like calcium hydrogen phosphate is prepared by reacting phosphoric acid with an alkaline calcium compound such as quick lime, in the presence of a multivalent organic acid with coordinating ability, such as citric acid, to obtain a columnar calcium hydrogen phosphate, and then hydrothermally treating the obtained columnar calcium hydrogen phosphate at a temperature of 60° C or higher.

Title: Antenna system
Inventor: WHITING IAN G
IPC: F41G7/22
Filed: 1994-10-26
Abstract: The invention relates to a phased array antenna by means of which, besides normal radar transmissions, also a guidance of a number of .semi-active homing missiles can be effected.      The main problem to be solved here is that a rear-reference signal for each missile remains present to a sufficient extent also during the periods covering normal radar transmissions. The invention solves this problem by transmitting rear-reference signals for all missiles deployed, simultaneously with a radar transmitter signal.

Title: Fair allocation of excess resources
Inventor: WOLFF MARK
IPC: H04L47/21
Filed: 1994-12-14
Abstract: In a communications system, a method is described for controlling the excess usage of a finite resource through which information flows by a plurality of sources having an "excess" state. For each source a determination is made as to whether the source is in the excess state. If the excess information rate is less than a predetermined fair information rate, the information is passed to the resource. If the excess information rate is greater than the fair information rate, the information is discarded.
Patent CA-2139023-A1 (CA)
Inventor: HASSLER STEPHEN P
IPC: H01H85/157
Filed: 1994-12-23
Abstract: Abstract of the Disclosure A current-limiting dropout fuseholder includes multiple current paths through the fuse body. A primary current path includes a high current fusible element. A secondary current path in parallel with the primary path includes a triggering conductor that extends outside the fuse body and is connected to a moveable support. The second current path further includes a first spark gap for severing the triggering conductor upon the occurrence of a fault and the shifting of the fault current from the primary current path to the second current path. A second spark gap formed between the primary and the second current paths ensures that the fault current flows across the first spark gap for a time sufficient to sever the triggering conductor, thereby ensuring that dropout will occur.

Title: Process for dust-free enzyme manufacture
Inventor: ANDELA CARL S M
IPC: C12N9/64
Filed: 1994-05-18
Abstract: New enzyme granules are provided with improved properties. The granules are based on core particles having a good pore size and pore size distribution  to allow an enzyme solution to enter into the particle. Accordingly, the core material comprises the enzyme in liquid form, thus eliminating the drawback of processing powdered enzymes. Still, good flowability and metering properties are obtained. The enzyme-containing granules are preferably coated with a film-forming macromolecular material. These granules have lower dustiness and improved mechanical strength. Also a method of preparing these enzyme granules is provided.

Patent CA-2142634-A1 (CA)
Title: Self-lubricating implantable articulation member
Inventor: CALDARISE SALVATORE
IPC: A61F2/32
Filed: 1995-02-16
Abstract: Implantable articles, such as bone prostheses, are prepared by casting techniques and have incorporated therein fluid communicating passageways. The internal fluid communicating passageways convey synovial fluid from a joint space to the articulation surface of an artificial joint. The presence of synovial fluid at the articulation surface provides sufficient lubricity to the joint and enables artificial joints to utilize metal/metal, metal/ceramic, and ceramic/ceramic articulation couples without the need for a low friction polymeric lining material. Accordingly, artificial joint components formed according to the present invention are less likely to develop wear debris. The implantable articles are formed by a casting process from casting molds that are prepared using a three dimensional printing technique.

Patent CA-2144801-A1 (CA)
Title: Method for making uncreped throughdried tissue products without an open draw
Inventor: RUGOWSKI JAMES S
IPC: D21F2/00
Filed: 1995-03-16
Abstract: A method for making uncreped throughdried tissues is disclosed in which the dried tissue sheet is fully supported by a fabric up to the reel. This method eliminates the open draw between the throughdryer and the reel and thereby eliminates sheet breaks normally associated with such open draws. In addition, the machine direction strength of the sheet can be reduced since the added strength is not needed to traverse the open draw normally present in current processes. Reducing the MD  strength in turn enables the production of more square, less stiff sheet, which improves the tactile properties of the product.

Title: Method of preparing reduced fat foods
Inventor: HARRIS DONALD W
IPC: A23L9/20
Filed: 1993-10-28
Abstract: A method of preparing reduced fat foods is provided which employs a retrograded, hydrolyzed, heat-treated, and fragmented, amylose starch. Amylose is precipitated and hydrolyzed with acid or .alpha.-amylase, solubles are removed by a heat treatment and the resulting solids are then fragmented to form an aqueous dispersion that is useful in replacing fat in a variety of food formulations.  The amylose can be derived from a native starch which contains amylose, e.g. common corn starch and high amylose corn starch, by gelatinizing the starch followed by precipitation of the amylose.

Patent CA-2157021-A1 (CA)
Inventor: BURNHAM WARREN R
IPC: B29C53/56
Filed: 1994-03-15
Abstract: An ultra small diameter reinforced catheter or the like type of tubular product is produced by winding reinforcing strands (20) on the surface of a plastic tube (22) and introducing the same into a heated die (16) which compresses the strands (20) against the tubing (22) and at the same time heats and softens superficial portions of the tubing wall with both conductive and radiant heat. This allows the strands to sink into the tubing wall. Following this, the compression and the conductive heating are removed while the tubing continues to be exposed to radiant heat from the die. During this last stage (III), the tension in the strands induces the strands to assume a predetermined position between the inner and outer surfaces of the tubing.

Filed: 1995-11-15
Abstract: An erbium-doped fiber amplifier (EDFA) is comprised of a pre-amp and a post-amp, which are connected in series, a photocoupler, a long wave pass filter (LWPF) and an LWPF controller.  The photocoupler is on an input-stage of the EDFA for entering the light signal in the LWPF controller.  The LWPF is between a pre-amp and a post-amp, and its cutoff wave-length can be adjustable.  A short-wavelength-part of the light signal which is amplified by the pre-amp, is cut off by the LWPF.  The LWPF controller detects an input signal power of the input light signal and adjusts the cutoff wavelength of the LWPF based on the detected input signal power.  Gain of light signals which are output from the post-amp, are equalized ranging the extensive input signal power and covering wide signal-wavelength bands.
