Title: Method of providing a patterned surface on a substrate
Inventor: MUCCI MICHAEL V
IPC: B24B1/00
Filed: 1992-02-05
Abstract: ABSTRACT OF THE DISCLOSURE            This invention relates to a method of providing a predetermined pattern to the surface of a workpiece, and, more particularly, a method for providing such a pattern by means of abrading.  Many articles, e.g., boats, airplanes, skis, air foils, mixing blades, have fluids flow over their surface.  Such fluids include air, other gases, liquids, and semi-solids.  The roughness of the surface of the article is critical, because it directly affects how efficiently the fluid flows over the article. The more efficiently a fluid flows, the less energy is required to transport it.  It would be desirable to provide an efficient method for treating the surface of a workpiece such that the surface will be provided with the type of profile that promotes efficient flow of fluids over it.  This invention provides a method of treating a workpiece by an abrasive article, the surface of which has a specified pattern.  The abrasive article comprises a backing having at least one abrasive composite bonded thereto.  The abrasive composite or composites comprise a plurality of abrasive grains dispersed in a binder.  The abrasive composite or composites have a predetermined shape and are disposed in a predetermined array, which typically consists of a plurality of peaks and valleys. As a result of the method of this invention, the surface of the workpiece can be provided with a profile that is similar to or substantially identical to the inverse of the pattern of the abrasive article.

Abstract: A B S R A C T            The present invention relates to a method and an arrangement for supplying direct current to a telephone line (ab). According to the invention, the current supply characteristic is programmable. The arrangement comprises a direct current supply circuit which detects the line voltage (Uab) and supplies a line current (Iab) in accordance with a preprogrammed current supply characteristic.            The circuit includes a first more high-voltage part (1) and a second more low-voltage part (2), in which programming of the-current supply characteristic takes place. For the purpose of achieving programming, a first resistive component (RA) having a programmable resistance is arranged essentially parallel with a capacitor (C1)  in the second part (2). The first resistive component determines the supply resistance of the circuit for low line currents. For the purpose of programming the characteristic, the circuit also includes a voltage limiting element (7) having a programmable reference voltage connected in series with a second resistive component (RB) having a programmable resistance, which are arranged substantially in parallel with the capacitor (C1). The reference voltage determines a limit line current (Ilim) at which current limitation occurs and the second resistive component (RB) determines, together with the first resistive component (RA) the supply resistance of the circuit at current limitation. Finally, the polarity of the idling voltage (E) of the circuit is also programmable.

Abstract: To insulate buildings, especially roofs and outer walls, against heat and/or noise, the system often used is to fit webs (12) or sheets (2, 3, 4) of mineral wool between abutments (27, 28) like rafters. On one side of the webs or sheets is adhesively secured or applied a foil as a vapour guard (5), the free longitudinal strips of which are folded inwards once or several times so that at least one longitudinal edge of the webs (12) or sheets (2, 3, 4) projects beyond the folded edge strips of the vapour guard (5).  The webs (12) are packaged in rolls or the sheets (2, 3, 4) in stacks for packaging. To enable the webs (12) or sheets (2, 3, 4) to be easily fitted into the differing widths between abutments (27, 28) and facilitate both prior manufacture and handling on fitting, it is proposed that part of the projection of the longitudinal edge of a width at least equal to that of the greatest difference between different distances between the abutments (27, 28) is directly separated from the packaging unit (1) for fitting to every distance (40) between two abutments (27, 28) less a slight extra width.

Title: Exercise and video game device
Inventor: HALL-TIPPING JUSTIN
IPC: G16H20/30
Filed: 1990-12-20
Abstract: An exercise device, such as an exercise bicycle, is connected to a speed sensor indicating activity level, e.g. speed of the bicycle. The activity level signal, along with a heart rate signal, are provided to a video game, such as a Pac-man type video game.  The game monitors the heart rate of the exerciser. If the heart rate falls outside preset minimum or maximum limits (steps 60, 62), a certain action occurs in the game, such as an increase in speed or skill level of the opposition (steps 64, 66). In the Pac-man type game for example, should the heart rate fall below the desired workout rate, the villain (the goblin) would move at a speed faster than the players' speed, putting the player at a disadvantage. The player would respond by increasing his level of physical activity, thereby increasing the heart rate until it exceeds the minimum aerobic level required, at which time the villain's speed would return to its normal level.
