Abstract: A golf training and practice apparatus is constructed with two major parts. The first part is a central hub from which four pointers extend in the direction in which the. golf ball is intended to be struck, towards the golf ball itself to indicate where it should lie, toward the feet of the golfer to indicate where such feet should be placed and a fourth tail of the target pointer which provides a longer path for aiding the visualization by the golfer of the intended path of the ball as well as an additional guide for one foot. The second major portion of the invention is a club face aligner which is attached to the ball pointer and allows the club face to be arranged at discreet angles matching the angles of the club face aligner just prior to swinging the club back and bringing it down into contact with the ball.
Abstract: A continuous strip is electrolytically coated in an electrolytic coating bath using a thin flexible or resilient dielectric wiping blade to wipe bubbles of hydrogen from the surface, sever dendritic material, if such is present as the coating thickens, and to remove a surface layer of partially depleted electrolytic solution, replacing with fresh solution and to stabilize strip portions extending between support rolls. The resilient dielectric wiper blade is preferably used with perforated anodes which allow fresh electrolytic solution to flow into the space between the anodes and the strip surface after being expelled by passage of the strip past the wiping blade. The orifices in the anode may be differentially sized to eliminate cavitation behind the wiping blades. The wiping blades may be chevron shaped to increase the wiping effect and pumps may be used to increase the flow of electrolytic solution into and out of the space between the anodes and the strip.

Abstract: An oiless surface for a bowling lane is formed from a high-density polyolefin and particularly a high-density polyethylene having a reduced friction surface with alternating high and low points. During bowling, a bowling ball passes over the high points without touching the low points, increasing the apparent lubricating of the surface to a point where no oil application to the surface is necessary and such surface can be referred to as "oiless". The oiless surface bowling lane is preferably provided in the form of a single continuous sheet forming such surface which may be transported to the lane site in a coiled condition and is also preferably retained tight against the lane base during actual bowling by a vacuum system which may also be used with other or non-oiless bowling surfaces.

Abstract: Drilling apparatus (50) for producing drilled holes with undercuts, with a drill (15), the drill shank (19) of which has a side cutting edge (14) protruding radially beyond the periphery (18) of the drill shank, and, on its circumference, opposite the side cutting edge (14), has a flattening, which makes possible the insertion of the side cutting edge (14) into the drilled hole, and the drill shank (19) of which is firmly connected with a connecting coupling (20), which is disposed in an articulated fashion between the drill (15) and a drill driving mechanism, permits wobbling motions of the shank as the drill (15) is rotating and has a drill shank-side coupling (29) with an axially movable indentor (85), which can be supported on an inclined plane (17) of a coupling (29) connected with the drill shank (19), which inclined plane (17) brings about the radial advance of the side cutting edge (14).
Abstract: Detrimental buildup of tramp photoresist material upon the positioning pads of a stage plate for wafer printing machines is prevented by providing an arcuate point contact surface upon the positioning pads. The wafer is supported a predetermined focal length from the photoresist light curing source by said point contact support. The arcuate surfaces do not tend to collect deposits of adherent tramp photoresist material. The arcuate positioning surfaces are formed from a smooth, hard material. Preferably, the arcuate surface is provided by a hard ball bearing recessed into the surface of the pad and is adjusted during set up by a rod applied to the inside surface of the ball bearing which remains after adjustment of the arcuate surface to the proper position and serves as a reinforcement for the arcuate surface. The surfaces of the positioning pads are preferably mechanically cut back to accommodate the arcuate positioning surface in a retrofit installation.
Abstract: Thick layers of hard dense chromium coatings are formed on metal substrates by an electrolytic brush plating operation in which a lead-tin anode is closely positioned to a cathodic workpiece in full anode wrap relationship and the surface of the cathodic workpiece is wiped by an open construction wiper to remove hydrogen bubbles and/or outwardly extending dendritic coating material with minimum contact with and force upon the coating surface. The open wiper construction allows free access to the coated surface at all times of fresh undepleted coating electrolyte and allows hydrogen bubbles and dendritic material to be discharged unimpeded from the wiper structure.
Abstract: A linear guide is provided with two parallel guide rails (4), which are disposed so as to protrude on either side of a rail body (2) and run parallel to one another, and a carriage (5), which is longitudinally displaceable on the guide rails (4) and is supported in double-track fashion at two different places on the periphery of each guide rail (4) by, in each case, two linear ball bearings (7) placed in lateral supporting side walls (6) of the carriage (5) embracing the guide rails (4).In order to achieve an even simpler and more precise, tolerance-free adjustment of the linear ball bearing and also to be able to adapt these to guide rails of different diameters and, in addition, also to be able to compensate for any angular errors between the guide rails (4) and the guiding carriage (5) rolling on them, each linear ball bearing (7) is adjustably supported individually for itself in the supporting side walls (6) of the carriage (5) transversely and, in particular, radially to the associated guide rail (4).

Abstract: Processing of data in a higher language database management system is speed enhanced by the use of an external utility or subprogram which determines the amount of free memory available in working memory and selects a plurality of consecutive records from mass memory files which are then transferred as a file unit into a virtual record storage buffer in the working memory leaving just sufficient free working memory to accomplish required processing. The data in the records in the virtual record storage buffer is then continuously processed in the normal manner but without any time consuming intermediate selection of records. In improved versions of the method, the records are read initially into a primary buffer and process records are output through a secondary buffer which is desirably the same as the primary buffer. The utility is written in assembly language for additional speed.
Abstract: The uniformity and suitability of fractural glass derived from breaking used fluorescent tubes for separation of the glass and potentially toxic powder adhered to the fractured glass prior to disposal and recovery of the components glass and powder is improved by use of a fracture blade having a sharp striking point extending forwardly from a base composed of a flat transversely oriented rotatable striking blade. The blade is preferably, for best results in later separation of the glass particulates and powder, operated at a striking blade speed of 1760 to 3700 feet per minute, providing a uniformity and size of fractured glass upon which a significantly more effective countercurrent air separation can be made.
