Abstract: A viewing glass used through which measurements are displayed which comprises a groove (5) having a shape parallel to the movement of an indicator needle. Displaceable markers are placed in the groove in order to denote the limiting positions of the measurements being made.

Abstract: An optical printing device includes a photosensitive means having a photosensitive surface and an optical print head. The optical print head has a plurality of arrays of a plurality of light emitting devices selectively energized and an optical means to form light images from the light emitting devices on the photosensitive surface.A plurality of the light emitting device arrays are arranged in a plurality of rows, with the light emitting devices aligned in a common direction with the arrays.The optical means comprises a plurality of graded index optical fiber arrays causing light images from the light emitting devices to be formed in a single line on the photosensitive surface.

Abstract: Thermal printing device is disclosed which prints on ordinary paper using an ink which melts when heated but is solid at room temperature.

Abstract: A stand for sheet music and the like comprises a first leg having a longitudinally extending non-circular bore open at one end, a shaft having a cross section corresponding to said bore and slidable therein through said open end, a pair of additional legs pivotally secured to the first leg at a substantially common location for movement between a collapsed position wherein the legs are aligned with the first leg and an open position wherein the additional legs extend outwardly from the first leg and the three legs collectively define a pyramidal base. The stand also includes a support for the sheet music and means for securing the support to the free end of the shaft for movement between a collapsed position wherein the support is aligned with the first leg and an open position wherein the support extends beyond the free end of the shaft and the weight of the support is distributed about the vertical axis of the base.

Abstract: A shoe upper easily connected by a connecting device to a lower member or mid sole having a lattice structure. The shoe also includes additional connecting devices to releasably connect the heel to the mid sole and upper. The outer sole is connected to the mid sole by glue or double-sided tape. The mid sole is made from a synthetic material which allows breathing through the apertures in the lattice structure. Also, the outer sole and heel are removeably attached to the mid sole and upper to provide a shoe that may be resoled and reheeled inexpensively using ordinary tools.

Abstract: The top frame of a vehicle seat is fitted with upper longitudinal guides for slidably mounting the frame on an articulated system which serves to displace the seat in a vertical direction while also permitting horizontal displacement of the seat in sliding motion. The upper guides are locked in any desired longitudinal position by means of catches and may be disengaged by means of a release control member.

Abstract: Game board apparatus and method for at least two players for simulating the play of soccer is disclosed.

Abstract: A microcomparator for elevation measurements having an amplification mechanism (3) which consists of a lever (31), the lever transforming the linear movement of a feeler (5) into a circular movement, and a lever arm (32) formed at least partly by calibrated rods (36) juxtaposed parallel to each other. The feeler (5) engages one of the calibrated cylinders (36) in accordance with the desired amplification factor without requiring altering the zero set for each change of scale. The amplification mechanism (3) and the display means (4) are fixedly connected with a carriage rotatably mounted on the housing (1) allowing a zero setting in such a manner that the display means always shows the same zero point as a function of the carriage (2). The microcomparator may also contain an automatic device for taking off measurements and a window containing a groove in which tolerance indicators may be carried.

Abstract: A dynamic system for the utilization of solar energy which is most of the time in the ideal position in relation to the sun. Said device comprises at least one unit consisting of a solar collector and a stand carrying said collector, means for rotating the solar collector around its horizontal axis and means for rotating the solar collector and/or the stand around the vertical axis; means for simultaneous or independent actuation of the rotation means, means for the tracking control of said actuation means; and means for the transfer of the energy obtained.
