Abstract: An electrochemical machining technique involves moving a cathode (2) towards an anodic workpiece (1). A current is passed through an electrolyte which flows between the cathode (2) and workpiece (1) so as to cause material to be removed electrolytically from the workpiece (1). A vibratory movement is imposed on the cathode (2) and the current passed between the cathode (2) and workpiece (1) is also varied. The vibratory movement may consist of a main sinusoidal oscillation and a secondary ultrasonic vibration, and the current variation is synchronized with the main vibration so that current pulses, and ultrasonic vibration pulses, coincide, with a predetermined small phase shift, with peaks of the main vibration corresponding to the smallest gap between the cathode (2) and workpiece (1).

Abstract: A lamp assembly, particularly for an entertainment machine, is made from one or more LEDs soldered to a printed circuit board (pcb). The pcb has an edge region with contacts which is constructed to fit into a lamp holder. The lamp assembly can be used in substitution for a conventional wedge-based push-fit bulb. The pcb edge region may be constructed so that it can only fit one way round in the lamp holder, or the pcb may include circuitry which allows connection either way round (either polarity).

Abstract: A multiyear calendar in the form of a multipage, book-like assembly with a standard page and 14 leaves on top thereof, each leaf rotatable along an edge seam to expose another leaf below. The standard page has a two dimensional array which graphically presents the basic information of the day and date for any given month in any given year. Each of the leaves lists the years for which it is used and a vertical array of 12 symbols each designating a month of the year and usable, in conjunction with the standard page, to determine the first day of each month.

Abstract: A system for handling stiff but flexible discs, particularly semiconductor wafers, including fail safe mechanisms that prevent the disc from being dropped if power to the unit is interrupted. Also, the electronics controlling operation resumes functioning at the point in the operation cycle existing when power was interrupted. A wafer hand assembly member is slipped under a wafer, or between parallel stacked but spaced wafers, and one or more fingers are rotated 90° to a position perpendicular to the plane of the stiff hand assembly member. The hand assembly also has one or more posts positioned perpendicular to the surface of the hand assembly. The finger(s) and post(s) or rear barrier constitute three upright projections or points forming the corners of a triangle with the wafer to be grasped there between.

Abstract: Light emitters are formed and patterned on an electrode for an organic light-emitting device by electrochemically polymerizing a monomer across the full length of the electrode. A second electrode is deposited so to define a pixel region between mutually aligned portions of the two electrodes. Electroluminescence of the emitter occurs when a voltage is applied across the electrodes of the device.

Abstract: Marker compounds indicative of variations in physiological conditions, genetic defects or disease states have been found to be present in apocrine sweat and, in many conditions, these markers are present in apocrine sweat in elevated levels when compared to blood. These markers are collected and/or detected in apocrine sweat and used as an indicator that a disease state or particular physiological condition exists. A skin patch, wipe or electronic detector for vapors released from apocrine sweat are used to indicate the existence of a disease state or changing physiological condition. The patch or wipe can include in monoclonal antibodies or other chemical compounds that can indicate the presence of specific markers. This may include indicators that render visible, the existence of a reaction between the monoclonal antibody or chemical compound and the marker compound to indicate the existence of the condition being tested for.

Abstract: A number of spaced apart first and second cavities are continuously formed in first and second thin sheets of material, respectively. Each of the first and second cavities has an edge at an opening thereof. The formed first and second cavities travel in paths that are downwardly inclined from the horizontal and approach each other. A number of first bodies are fed into the first cavities, respectively, where each of the first bodies has a liquid tight interior cavity that contains a volume of a first liquid. This liquid is one that when mixed with a second liquid starts a chemiluminescent reaction. The edge of each of the first cavities is sealed progressively with the respective edge of a second cavity, while injecting the second liquid into one or both of the first and second cavities that are being sealed. This forms a liquid tight second body that contains the first body and a second volume of the second liquid.

Abstract: An infusion catheter with an adjustable flow contains a flow restrictor tube located in the lumen of the catheter. The flow rate through the infusion catheter can be adjusted by reducing the length of the flow restrictor tube and infusion catheter assembly.

Abstract: A crutch constructed of two adjacently located, elongated, parallel upper and lower bows which can be moved in relationship to each other to form a vertical support of readily varied length. These bows have the same design and are therefore interchangeable, significantly reducing inventory requirements. Each bow has a series of parallel horizontal notches with the bows positioned so that the notches on each bow are on contacting surfaces. A pin inserted into parallel, adjacent notches on the two bows in cooperation with two or more collars or caps on the ends of one end of each bow fixes the relationship between the shafts which, in turn, defines the length of the vertical support. A similar concept can be used to lock a moveable centrally located lower bow between two parallel outer upper bows. This assemble provides a strong, adjustable length crutch for any height patient using only two different pairs of bow lengths.

Abstract: A blade and a blade assembly wherein the blade has a front, beveled, sharpened edge, two side edges meeting at a point spaced from the front edge and at least one attachment structure extending outwardly from each side edge. A blade holder, which extends beyond the side edges and attachment structures of the blade, sits on a top surface of the blade and is attached to the blade by a portion thereof which receives the attachment structures. The holder has an opening in an exposed surface to receive an extension from a drive mechanism such that when the drive mechanism is activated the blade is caused to vibrate or oscillate. The blade is oscillated in a lateral fashion when driven by a rod rotating along a circular path.

Abstract: Boron neutron capture therapy can be used to destroy tumors. This treatment modality is enhanced by delivering compounds to the tumor site where the compounds have high concentrations of boron, the boron compounds being encapsulated in the bilayer of a liposome or in the bilayer as well as the internal space of the liposomes. Preferred compounds, include carborane units with multiple boron atoms within the carborane cage structure. Liposomes with increased tumor specificity may also be used.

Contact between the pad and the abrasive disk is brought about or increased by application of a vacuum through the tube to the skin surface.

Abstract: A new and improved tube or catheter for administrating or withdrawing a substance from the human body which can be temporarily attached to the tissue site. The catheter consists of a dual lumen, side-by-side, tube. One lumen is used to administer or withdraw a substance. The second lumen contains an attachment means consisting of a loop of filament extending beyond the both ends of the lumen in the second tube. During use the surgeon fixes a suture at the tissue site and ties the suture around the filament loop extending from the distal end of the second tube. The surgeon then grasps the proximal end of the filament and slides the catheter over the filament and the suture until it rests against the tissue attachment site. The filament or suture is then tied around the proximal end of the tube to hold the catheter in place. To remove the catheter, the surgeon cuts the suture where tied to the proximal end of the tube, pulls off the catheter, and slides the suture out of the tissue.

Abstract: A graphic user interface, such as a standard functioning mouse or track ball, which has the shape and/or appearance of various different characters, such as animals and which may be sized for use by children. The graphic user interface also has various removable and interchangable parts so that its appearance can be changed without interfering with functioning of the device. The graphic user interface can have added features such as sound an/or light generating features so that normal operation of the buttons causes the production of a sound or sounds which depends on the shape applied to the graphic user interface. Depressing the buttons can also cause bulbs or LCDs positioned on the graphic user interface body, particularly in the eyes of the character, to light.
