Abstract: A method and apparatus for achieving uniform density of image elements of a 3-D photograph by using a 3-D printer with a linear motion blade shutter which travels at varying speeds during printing a negative view to control the duration of exposure across the 3-D photograph.  The scanning speed of the linear shutter is varied during the exposure of each of the 2-D negative views and is based upon the position of the 2-D negative view in relation to the field of illumination of the enlarging lens in order to compensate for the non-uniformity of  illumination due to the vignetting effect.

Title: Method suitable for renovating building facades
Inventor: KUBBUTAT ALBERT
IPC: E04F13/04
Filed: 1991-02-06
Abstract: ABSTRACT      The proposed method serves the renovation of building facades comprising an outer layer (2) in the form of an older layer  of  plaster,  which  is  preferably a heat  insulating composite material or material possessing similar properties. Very thin, rigid plaster base panels (4), whose thickness does not exceed 10 mm, and is preferably less than 8 mm, are first secured to the existing outer layer (2) with the aid of a bonding agent (3) or other suitable material.  Next, holes (5) are drilled through the plaster base panels (4) and into the base brickwork (11.  At the same time, recesses, whose depth is less than the thickness of the plaster base panels (4), are created in each plaster base panel in the region of the drilled hole.   By  inserting into the hole a dowel-pin  (6)  that completely fills in the hole that has been drilled into the brickwork (1), and whose flat head (7) at least partially fills in recess (8), plaster base panels (4) are secured in their glued-on position.  Finally, a layer of fresh plaster (9) is applied to the whole facade panel structure that comprises plaster base panels (4) (Fig. 2).

Title: Preparation of di-cation ethers
Inventor: CHAPMAN DEREK D
IPC: C07D213/89
Filed: 1990-08-23
Abstract: PREPARATION OF DI-CATION ETHERS                Abstract of the Disclosure Di-cation ether salts are prepared by a reaction sequence which comprises (i)  N-alkylating a 2-halopyridine, (ii) reacting the N-alkylated product with a 2-hydroxypyridine in the presence of sufficient organic base to combine with the by-product hydrohalic acid, and (iii) reacting the mono-cation ether thereby produced with an alkylating agent. The process is conducted in the presence of a solvent, such as acetonitrile.  The di-cation can be isolated by removal of the solvent, followed by contacting the reaction mixture with an aqueous fluoborate, whereby the di-cation ether precipitates as the fluoborate salt.  The di-cation ether is prepared in surprisingly high yield.  The process can be conducted in one reaction vessel without isolation of a product intermediate formed in the reaction sequence.  The fluoborate product is quite pure.  If desired, the fluoborate anion can be removed from the di-cation ether by suspending the di-cation ether fluoborate in water, and reacting it with a potassium salt such as KNO3.  The soluble di-cation product thereby produced can be used as a gelatin hardener, or as a chemical intermediate.

Patent CA-2036167-A1 (CA)
Inventor: GOTO SHOJI
IPC: G11B7/085
Filed: 1991-02-12
Abstract: An  optical  unit  actuator  for  an  optical information  recording/reproducing  apparatus  includes  an electromagnetic drive mechanism composed of a coil and a magnet cooperative to drive an objective lens mounted on an optical unit.  One of the coil and the magnet is secured to the optical unit.  The other of the coil and the magnet is held on a fixed unit with an elastic support member disposed therebetween, the fixed unit being immovable as against the movable  optical  unit.     The  elastic  support  member substantially dampens or takes up vibration caused by a reaction force caused as a result of acceleration of the objective lens when the objective lens is driven to follow a dynamic radial  runout and an axial deflection of an optical  disk.    With  the  elastic  support  member  thus provided, an optical component, a photoelectric transducer or the optical disk which is disposed on the side of the fixed  unit  is isolated  from  vibration.    The  control characteristics of a system including an optical head, the optical disk and a control circuit for the optical head can, therefore, be improved.

Title: Direction indicating fault indicator
Inventor: SCHWEITZER EDMUND O JR
IPC: G01R31/08
Filed: 1991-08-21
Abstract: A fault indicator for indicating the occurrence and relative direction of a fault current in a power transmission or distribution system includes a rotatably mounted indicator flag. The indicator flag is actuated 90° clockwise or counterclockwise from a central reset position to up-line indicating or down-line indicating trip positions by a compact magnetic pole piece assembly having three radially extending magnetic pole segments which interact with four magnetic poles on a magnetic armature rotatably coupled to the indicator flag. A pair of magnetic windings magnetize the pole segments upon the occurrence of a fault current to rotate the flag from the reset position. A second pole piece and winding directionally actuated in response to the direction of the fault current determines the direction of rotation of the indicator flag to indicate whether the fault is upline or downline relative to the indicator.

Abstract: ABSTRACT OF THE DISCLOSURE:         An anticalculus oral composition, which is preferably a toothpaste or a mouthrinse, includes an effective anticalculus azacycloalkane-2,2-diphosphonic acid or a salt thereof, prefer-ably azacycloheptane-2,2-diphosphonic acid, and a water-soluble or water swellable polymer having a molecular weight of about 1,000 - 2,000,000, such as a linear copolymer of maleic anhydride and vinyl methyl ether or a polyvinyl phosphonate. The polymer surprisingly increases the anticalculus effectiveness of the azacycloalkane-2,2-diphosphonic acid or salt thereof in such compositions, even as comparatively low concentrations of both such materials.  Also within the invention is a process for apply-ing such compositions to the teeth, and it has been shown by both in vitro and in vivo testing that significant repeatable improve-ments in anticalculus effects are obtained by such processes, compared to control processes in which either of the active components mentioned is employed alone in the described oral compositions.
