Abstract: PREFABRICATED PAVEMENT MODULE            ABSTRACT       A light weight pavement module is described which comprises a base grating, an impervious intermediate layer, such as a reinforced plastic or fiberglass sheet applied over the base grating, and a concrete top layer wear surf ace applied over the intermediate layer. The intermediate layer prevents the concrete top layer from penetrating through the base grating. The grating has shear connectors which pierce the intermediate layer and project into the top layer wear surf ace in order to form an integral pavement module. The pavement module may be formed without an intermediate layer if the module is otherwise constructed so that the top layer wear surface does not pentrate and fill the interstices of the base grating.

Abstract: CURRENT CONTROLLER FOR HEATING STAGE ON LEITZ MICROSCOPE       Abstract A current controller interface accepts a variable voltage at its input and develops a current at its output which corresponds directly with the input variable voltage.  Its apparatus is usually associated with a program controller as an input and a microscope which has a heated element as the output. The apparatus uses a control circuit which is coupled to a controllable resistance semiconductor device, which device has an output which varies in resistance in accordance with variation in input current.  The output of the variable resistance device is coupled in series with the heating coil of the microscope, the power supply and current sensing resistor.  The resistor develops a feedback voltage which is applied to the control circuit so that when a change in voltage is applied to the input the output from the current sensing means will change until it balances the current being applied at the input.  When the balance occurs, no further change in output current will occur.

Abstract: A B S T R A C T     Two platens having glass plates are pivotally interconnected by means of hinges and U-shaped brackets. Spring loaded fasteners hold the platens closed but the fasteners may be opened to permit the platens to pivot open. The two platens are seated one on top of the other upon a housing within which are mounted lamps which produce ultra-violet rays. The position of the platens can be reversed so that the lower platen is on top of the upper platen.    There is a cavity between the closed platens for accommod-ation of a negative, a layer of photo-sensitive composition and bearer strips. The photo-sensitive composition is exposed to the ultra-violet rays first on one side then on the other by reversal of the positions of the platens so that both a base on one side and a raised image on the other side are formed. The thickness of the bearer strips governs the thickness of the finished printing plate.    The brackets and fasteners bias the platens together with resulting pressure upon the photo-sensitive composition within the cavity during the time that the photo-sensitive composition is exposed to the ultra-violet rays.

Abstract: ABSTRACT : Hand operable controller.     A hand controller for use with a home electronic video game produces electrical control signals in response to manipulation of a control stick extending through an aperture in the controller housing. The control stick is attached to an actuator stem which forms part of a multi-position switch assembly within the housing. The switch assembly includes a helical coil spring which is attached at one end to an interior surface of the housing and is arranged to concentrically receive the actuator stem so as to support the actuator stem and control stick in an upright non-actuated position. Displacement of the control stick and actuator stem causes the helical spring to contact one or more of a plurality of electrical contac pads disposed generally concentrically around the spring. This causes appropriate control signal to be produced for application to the video game. The contact pads are shaped and positioned to create favored positions for the control stick which enhance the sense of control provided by the controller.

Abstract: PRECISION CONTROL FREQUENCY SYNTHESIZER HAVING AN UNSTABLE, VARIABLE FREQUENCY INPUT SIGNAL            Abstract The subject invention is a precision controlled frequency synthesizer which is capable of precisely adjusting the frequency of an output signal to maintain a desired frequency difference between an input and output signal regardless of the stability of the frequency of an input signal.  The synthesizer comprises the basic elements of a phase locked loop (PLL) type circuit.  The PLL circuit portion detects the actual frequency difference, a value A, between the input and output signals.  One reference source provides a desired frequency difference, a value D, which represents the frequency difference between a stable input frequency and a desired output frequency.  The difference between the frequency difference values A and D serves as the amount of adjustment to the frequency of the output signal.  This adjustment represents the amount of compensation necessary to maintain a specified frequency relationship  between the input and output signals.

Abstract: ABSTRACT     A ski, particularly an Alpine ski, where the  maximum  height (radius of curvature) of the bottom camber is in the rearward portion  of  the  ski  behind  the  centerline  of  the  boot placement; and the waist (minimum width of  side  camber)  of the ski is ahead of the centerline of the boot placement such that the ski width is increasing at this centerline position.     BACKGROUND OF THE INVENTION     This invention  relates  to  an improved ski design and more particularly to improve the  efficiency  of  Downhill  skis, Giant Slalom skis, Slalom skis and Recreational Alpine skis.     The  present ski design has developed over the years. The two key factors which affect the performance of  a  ski  are  the "camber"  which  is the upwardly bowed bottom surface and the "side camber" or "side cut" in which the forward end and rear end of the ski are wider then the center or waist of the ski.     Clement,  US  Patent  No.  2,258,046   issued   Oct.7,   1941 illustrates an early ski which incorporates camber. Beerli in Patent  2,210,794 issued June 6, 1950 illustrates the concept of "side camber".
