Title: Synthetic detergent bar and manufacture thereof
Inventor: CHAMBERS JOHN GEORGE
IPC: C11D3/37
Filed: 1994-03-14
Granted: 2000-07-18
Abstract: A detergent composition which is suitable for making into bars for personal washing comprises: (a) 10-60 %wt of a synthetic, non-soap detergent; (b) 10-60 %wt of water-soluble material which is neither soap nor a non-soap detergent and which has a melting point in the range 40 °CC to 100 °C; and (c) 5-50 %wt of water-insoluble material which is neither soap nor a non-soap detergent and which has a melting point in the range 40 °C to 100 °C. The content of water, if any does not exceed 20 %wt of the composition and better is less than 15 %wt. The materials (b) and (c) serve to give structure to the bars. The composition can be propared by melting together the above-mentioned components at a temperature of 50-100 °C, without the conventional energetic working. Desirably the molten mixture contains less than 20 %wt material, other than synthetic, non-soap detergent, which does not enter the liquid phase. The melt can be cast into bars or cooled, milled, plodded and stamped into bars.

Abstract: An extruded aluminum radiant heat transfer plate includes an integral elongated receptacle for holding and confining a plastic tubing.  The aluminum radiant heat transfer plate is extruded to provide heat transfer side edges in the form of thin-walled fins running the length of the extrusion.  Between the fins, the extrusion provides the elongated receptacle for the plastic tubing. The receptacle can take the form of a "C" (as it appears in cross section) that stands above the plane of the heat transfer fins.  The receptacle, alternately, can take the form of a "U" (as it appears in cross section), the legs of which integrally connect to the fins.

Granted: 2003-09-23
Abstract: It is described a method for automatic state control, inspection, cleaning and/or surface treatment of structures, especially measuring the thickness of plate constructions and pipes by means of ultrasound signals from a self propelled, remotely controllable unit (1). The self propelled unit (1) is continuously moved in the measurement area, and a transmitter (6) transmits an ultrasound signal in a direction substantially perpendicular to the surface of the construction. A reflected signal is received by a receiver (6), determining thickness and material quality of the construction at the measurement spot, on the basis of received reflected signal, and parameters such as transit time for the reflected signal. The self-propelled unit (1) performs self-positioning by means of previously known spots on the construction. All received data regarding waveform of the reflected signal is stored in a computer, and thickness and material quality are verified by comparing data for received signal in one spot, with data for received signals in adjacent spots. The steps are repeated for collection of data for new measurement spots.

Granted: 2003-10-07
Abstract: A capacitive pressure sensor (10) includes a conductive diaphragm (20) positioned between two pneumatically separate chambers (60, 64). The diaphragm is supported at its periphery by a concave base member (30). An electrode assembly (40) establishes a substantially planar conductive surface (42a) opposite to, and spaced apart by a nominal gap from, the conductive diaphragm. The electrode assembly includes the conductive surface and a single support element (44) secured to, and extending through the base member. A glass dielectric (46) fixes the support element to a collar (48) which may be welded, brazed, or soldered to the base member. The glass dielectric provides both mechanical support and high quality electric insulation between the electrode and the housing. By prefabricating the electrode support element with the collar and securing the collar to the housing after the dielectric has cured, problems associated with thermal expansion are avoided and the dimension of the nominal gap may be precisely controlled at low cost.

Title: Intraocular lens folder
Inventor: WOO YI-REN
IPC: A61F2/16
Filed: 1997-11-18
Granted: 2003-01-21
Abstract: A single piece intraocular lens folder that has a generally planar, open fra me in the shape of a rounded "A" with a rimmed, open head at the top of the "A" . The base of the "A" forms a pair of opposing legs or handles that join to fo rm a hinge at the intersection where the handles attach to the head. The hinge allows the handle to be squeezed together and spring apart when released. Squeezing the handles together causes the sides of the head to spread apart,  thereby stretching the top edge of the head rim and pulling the top edge downward toward the hinge. The open head contains a pair of support jaws and  a pair of serpentine folding jaws. The location of the serpentine jaws is such  that when the top edge of the head rim moves toward the hinge, the serpentin e jaws are squeezed together, causing the IOL to be folded in half. The serpentine shape of the folding jaws allow the haptics to pivot downward, thereby permitting the IOL to be folded along a plurality of axes.

Title: Telescopic viewfinder optical system
Inventor: NEIL IAIN A
IPC: G02B25/00
Filed: 1998-11-19
Granted: 2004-02-03
Abstract: A variable length telescoping viewfinder for cameras that provides a variably adjustable eye viewing distance relative to the camera without changing the focus or magnification of the scene being photographed throughout the telescoping movement of the viewfinder. The light rays of the real image supplied to the viewfinder directly or indirectly from the camera are passed through a field lens, Pechan prism, relay lens system forming collimated light rays from the fixed front module to the movable rear module wherein lens elements form an intermediate image that is viewed through an eyepiece lens group. The front module is weakly powered and of a substantial effective optical length because of the inclusion of the Pechan prism. The image forming lens group of the rear module is weakly powered whereby relative telescopic movement between the front and rear modules does not adversely affect the location, focus or magnification of the intermediate image throughout the range of movement. A magnification lens group is provided for selectively magnifying the intermediate image by moving the magnification lens group into and off the optical axis. The Pechan prism also allows proper orientation of the image. The eyepiece lens group for viewing the intermediate image may include a movable lens subgroup for precise focusing to compensate for far-sightedness or near- sightedness of the human eye.
