Title: Symbol reader
Inventor: TAKENAKA SHINYA
IPC: G06K7/10
Filed: 1990-12-07
Granted: 1996-04-23
Abstract: A symbol reader for reading symbols on a symbol surface.  An optical system including a laser, condensing lens and a scanning mirror illuminate a symbol surface to be read with a laser beam, scanning across the symbol surface.  A transducer measures the amount of light reflected from the symbol surface.  A differential circuit develops a differential coefficient indicative of the change of light intensity as light scans the symbols being read.  A control system adjusts the optical system illuminating the symbol surface so as to maximize the differential coefficient, thereby minimizing the diameter of the light beam to allow for adequate reading at variable distances.

Abstract: A food-safe composition for the pretreatment of a surface, preferably an oven or a broiler, which may be subjected to heat is liable to soiling by organic food deposits, especially baked-on food deposits. A food-safe, inorganic thickening agent which is substantially insoluble in an alkaline aqueous composition and which is present in an amount sufficient so that, during application to the surface, the composition is capable of forming a continuous coating adhered to all desired portions of the surface, is combined with (1) an alkaline, food-safe, water-soluble inorganic salt in an amount sufficient so that the composition is readily removable with water or an aqueous solution after the composition has been dried and soiled and (2) a high-boiling, organic component selected from the group consisting of (a)    ethers having more than seven carbon atoms and (b)    aliphatic esters having carboxylic acid-derived portions of more than seven carbon atoms, wherein said high-boiling, organic component is present in an amount sufficient so that the continuous coating remains continuous as the coating dries. The composition forms a film after drying, preferably by heating, which remains continuous over all portions of the surface, including areas which may already be soiled with food deposits. After the film accumulates additional food soils, thesoiled film can be readily removed by contact with water or an aqueous solution.

Patent CA-2051960-C (CA)
Inventor: GLASER SIEGFRIED
IPC: E06B3/66
Filed: 1991-09-20
Granted: 2000-07-11
Abstract: The invention concerns a transom construction for the mounting between two glass panes, in particular window glass panes, in which the transoms that are assembled to form a transom cross consist of hollow profiles and at least two transverse profiles that are flush with each other are attached to a main hollow profile at a predetermined angle to create a transom cross and encompass the main profile in an overlapping manner. The connection of the hollow profiles to the transom construction is executed with the aid of connecting elements with insertion openings that extend in the longitudinal direction and can be solidly inserted into the transverse hollow profile. A  four-edged connecting pin is also provided, which penetrates the insertion opening in the main hollow profile and is fitted into the recess in the connecting elements. The connecting elements which are attached to each other by the connecting pins in a solid manner create a highly rigid skeleton that allows the use of very thin hollow profiles for transom construction.

Title: Microgap type surge absorber
Inventor: TANAKA YOSHIYUKI
IPC: H01T4/12
Filed: 1991-11-26
Granted: 1997-04-01
Abstract: A microgap-type surge absorber comprises a columnar insulator  element  covered with  a  conductive material  and provided with a microgap around the center thereof.  A pair of conductive caps are fixed on both ends of the element, and first and second electrodes are attached to both caps.   First and second glass tubes adhere to the periphery of the first and second electrodes, and surround the end parts of the element. A cylindrical third electrode is held between both glass tubes, and adjacently surrounds the element containing the microgap. The space defined by the first, second, and third electrodes and the glass tubes  is charged with inert gas.   When a glow discharge, started near the microgap, extends to the conductive coating and arrives at the caps, an arc discharge is formed between the caps through the third electrode.   The third electrode protects the microgap from damage from arc-discharge current.

Title: High temperature furnace
Inventor: CONOCHIE DAVID STEWART
IPC: H05B6/02
Filed: 1991-03-05
Granted: 1999-09-28
Abstract: A furnace configuration is disclosed which is suitable for scale-up of heat transfer limited processes performed at high temperatures, e.g: carbothenmic reduction of transition metal or rare earth oxides. The furnace is inductively heated by external insulated coils (3) and the susceptor (2), preferably graphite rings, is placed within the charge (1) away from the outer surfaces of the charge (1). Consequently heat is transferred to the charge (1) in three dimensions and the process approaches completion before the insulation (4) is subjected to high temperatures. As a result of this three dimensional heat transfer, larger furnaces are possible within the heat transfer constraints of these high temperature processes and higher yields are obtained.

Title: Method and apparatus for making wire nails having radially offset, fully circular heads
Inventor: WRIGHT ROBERT W
IPC: B21G3/16
Filed: 1992-12-23
Granted: 1998-09-15
Abstract: Nails  having  radially  offset,   circular  heads   are manufactured from a malleable wire.  The wire is clamped so that a leading portion extends axially from a clamping mechanism.  The extending portion is bent at an acute angle relative to a clamping axis.   The extending portion is cut so as to form a pointed end thereon and so as to leave a bent stub extending at such an angle.  Such a nail head is formed from the stub, which is pressed by a punch into a cavity defined by the clamping mechanism, and which is deformed when pressed thereinto.   The cavity has a fully circular, offset margin.  The punch has a face covering the cavity.   Once released, the wire is fed axially until a leading portion extends as before.  These operations are repeated to form a similar nail in each repetition.   A novel apparatus for carrying out these operations is disclosed.
Patent CA-2087013-C (CA)
Title: Multi-ply web former and method
Inventor: BLACKLEDGE JAMES
IPC: D21F9/02
Filed: 1991-07-04
Granted: 1995-01-17
Abstract: A multi-ply paper web is formed by bringing a top ply liner into ply-bonding engagement with a base ply web (WB) traveling on a base ply forming wire (36). The top ply liner (WT) is formed between two co-running forming wires (10, 20) in a convex upwardly/concave downwardly curved, substantially horizontal forming zone.  Dewatering in the forming zone is effected by applying sub-atmospheric air pressure solely beneath the lower surface of the top ply liner (WT) being formed. Water is removed from the upper surface of the top ply liner (WT) solely by wire tension, gravity and centrifugal force created by passing the co-running forming wires (10, 20) over the convex upwardly curved path of travel.  This permits a greater concentration of pulp stock fines to remain in the upper surface of the top ply liner (WT) to effect greater ply-bonding affinity with the base ply (WB) when the two plies (WT, WB) are brought together and bonded.

The catalyst is preferably formed by impregnating alkali metal sulfide and sulfide(s) or selenide(s) of metal(s) showing polyvalent and/or amphoteric character, e.g. Zn, etc. on a microporous type support (e.g., alumina). Its activity is sustained by exposure to a source of oxygen, such as air, oxygen sulphur dioxide or nitrogen peroxide and the like. A method is also described by whi ch sulphur dioxide may be absorbed from flue gas and converted to sulphur, while higher oxides of nitrogen and carbon dioxide  are being absorbed for subsequent recovery, utiliz- ing a catalyst that has been conditioned by prior exposure to a reducing gas .

Granted: 2002-04-16
Abstract: The invention relates to a platform body (10) covering mechanism comprising a flexible cover (11) and pulling devices op-erating in conjunction with each other, which pull the cover over the platform body and off it. The pulling devices comprise a pulling cable wire (13) for pulling the cover over the platform body and a drum (12) around which the cover is wound when it is removed from over the platform body.

The guides are made curved so that they are closer to each other at the centre part of the platform body. Thus, the reinforcement (14) will bend upwards to form a curve at the centre part of the platform body, so that the cover can be brought over the platform body even where the load (40) placed on the platform body is higher than the sides (31) of the platform body.
