Title: Aligning beaded fastener assembly for lighting fixtures
Inventor: SEVACK DAVID
IPC: F21S8/06
Filed: 1994-05-05
Abstract: A locking assembly for lighting fixtures or portable lamps is provided to facilitate the fast assembly and alignment of longitudinally extending arms, such as hollow tubular arms, either on the flat surface, or on the vertical exterior surface of a base of the lighting fixture or portable lamp, without the use of additional machined or cast fittings. A bead is formed near the end of the arm, wherein the bead includes one or more indentations made of rectangular, square, round or other shapes, so that a projection or projections protrude from the opposite flat surface of the bead.  The end of the tube beyond the bead is then threaded and if bent into an arm, the bending is done in the same plane as a line running through the center of the tube and one projection.  One or more rounded holes slightly larger than the diameter of the tube are provided in the flat surface of the plates or bodies or onto the vertical sides of the bodies of the lighting fixture or portable lamp.  These holes have on their circumferences one or more slotted or notched openings of such size so as to receive the end of the longitudinally extending arms and the projections of the bead, so that location of these holes is quickly located and the arms are aligned with the hole or holes in relation to the plate or body.  Upon passing the end of the tube or arm through the plate or body until the projections are located in the slots or notches, a nut is then threaded onto the end of the tube or arm and tightened.

Title: Stem torque sensor
Inventor: HEIMAN STEPHEN M
IPC: G01L5/00
Filed: 1994-06-02
Abstract: STEM TORQUE SENSOR                        ABSTRACT       A strain sensor device is attached to a cylindrical structural member for measuring the amount of twist of the member about an axis of rotation and includes a central beam, which is aligned parallel to the axis of rotation of the structural member and is   fastened in between two mounting members which are themselves fixedly secured to the structural member.  When torsion occurs in the structural member, the one mounting member will move in a relative direction parallel to the other mounting member but offset by the length of the central beam.  The central beam is significantly less rigid than the mounting blocks and bends to accommodate the movement.  Four strain gauges are secured to the central beam in a bridge circuit to measure bending of the beam.   The bridge circuit generates electrical signals proportional to the angle of twist and the torsional load on the structural member.  Additional strain gauges can be provided on a second beam, perpendicular to the  central  beam,  to measure  bending  of  the  second beam proportional to axial loads on the structural member.  Shaped blocks, which are adhered to the structural member, or clamps may be used as mounting members.

Title: Compact ROS Imaging System
Inventor: OSSMAN KENNETH R
IPC: G02B26/12
Filed: 1994-06-13
Abstract: The pre-polygon scanning path length of a raster output scanning system is reduced by replacing a required cylinder lens, or lenses, with two cylindrical mirrors. One mirror with a negative, concave surface and a second positive cylindrical mirror. The first mirror directs the light beam to the second mirror. The second mirror directs the light onto the facets of a rotating polygon to form a focused beam in the vertical axis of the polygon. The function of the two cylindrical mirrors is to act as a telephoto lens to properly focus the image of the laser at the polygon facet while reducing the total pre-polygon path length.

Abstract: A method of forming a template of an image of an object includes the steps of: detecting occurrences of at least one feature type within the image which meet a respective criterion; for each such occurrence, determining a feature position which is a point within the image at which the occurrence of the feature type is to be considered as being located; and constructing a structural mesh of links between the feature positions. A method is also disclosed of forming a template derived from a plurality of templates formed from respective images of different members of the class of objects and combining the templates to form a generalised template. In particular the templates are combined using a genetic algorithm. The invention provides a method of forming a template from one or more images which does not rely on a priori assumptions about the salient features of the object for which a template is to be obtained.

Title: Hydrocracking of Heavy Hydrocarbon Oils with Heavy Hydrocarbon Recycle
Inventor: SEARS PAUL L
IPC: C10G49/22
Filed: 1994-08-31
Abstract: A heavy hydrocarbon oil, a substantial portion of which boils above 524°C, is subjected to hydrocracking with a fractionated heavy oil recycle stream containing active additive particles.  In the process, a slurry feed of (1) fresh heavy hydrocarbon oil feedstock and a heavy hydrocarbon recycle and (2) from about 0.01-4% by weight (based on fresh feedstock) of iron sulphate additive particles having sizes less than 45 µm, is passed upwardly through a confined vertical hydrocracking zone.  A mixed effluent is removed from the top of the hydrocracking zone, which is then passed through a hote separator vessel.  From the bottom of the separator is withdrawn a liquid heavy hydrocarbon stream comprising heavy hydrocarbons and particles of the iron sulphate additive converted mainly to an iron sulphide phase. This separated liquid heavy hydrocarbon stream is fractionated to obtain a heavy oil which boils above 450°C, containing the additive particles.  The fractionated heavy oil containing the additive particles is then recycled to and mixing with the hydrocracking zone feed slurry in an amount up to 40% by weight of the combined feed slurry.

Title: Process and device for hair bleaching by laser irradiation
Inventor: CAISEY LAURENCE
IPC: D06L4/50
Filed: 1995-05-03
Abstract: A process and device are claimed for the cosmetic partial or complete lightening of hair colour. Hair is irradiated a lock at a time by passing through a laser beam strong enough to degrade the melamine in the hair, but not so strong that the keratin is damaged. Keratin in dark hair is degraded at a lower energy density than that in naturally light hair. Several irradiation passes are made on each lock of hair until the desired colour is achieved. The laser used has an energy density of 0.1-1.2 J/cm<2> at a wavelength of 532 nm. The energy density used varies, proportional to the wavelength.
