Abstract: ABSTRACT           A racing game formed of a plurality of equal length tracks.  A movable member is positioned on each of the tracks and contains a pair of track engaging members positioned thereon.  A pair of drives are movable along each of the tracks for advancing the position of the movable members along the tracks.  Each of the drives move at different speeds and are each formed of endless belts.          The drives are mounted so that they continuously move from one side of one track to one side of the adjacent track.  The drive is formed of a continuous length belt having randomly spaced teeth thereon.  As the belt moves the teeth cause the movable members to move along the track.  The track engaging members may be formed with different spacings for different movable members, thus increasing the probability that the interval of time that each movable member completes movement along the entire distance of the track differs for each member.

Abstract: ABSTRACT OF THE DISCLOSURE         In a tape editing system having a first or master VTR operable in a playback mode for reproducing video signals recorded on a first tape, and a second or slave VTR selectively operable in a playback mode for reproducing video signals previously recorded on a second tape or in a record mode for replacing a portion of such previously recorded signals with a portion of the video signals being simultaneously reproduced from the first tape; an editing control apparatus or unit is provided for precisely selecting the portion of the video signals on the first tape to be recorded on the second tape and the portion of the video signals on the second tape to be replaced by the selected video signals from the first tape.          The editing control unit has, for each of the VTRs, an up- and down- counter of addresses along the respective tape, a cut-in address memory for storing the content of the tape address counter at the commencement of the portion of the video signals on the tape selected with the respective VTR in its playback mode, a cut-in comparator providing an output upon coincidence of the content of the tape address counter with the stored content in the memory, and a reverse counter actuated by the output from the comparator during reverse movement of the respective tape to measure a predetermined distance from the cut-in address back to a stand-by address at which the reverse tape movement is halted.  Thereafter, during forward movement of both tapes simultaneously from their stand-by addresses, the second VTR is changed-over from its playback mode to its record mode in response to the output from at least one of the cut-in comparators.  Further, a cut-out address memory stores the content of a selected one of the tape address counters at the end of the selected portion of the video signals on the respective tape and, thereafter, during the simultaneous forward movement of both tapes, a cut-out comparator provided an output upon coincidence of the content of a selected one of the tape address counters with the stored content in the cut-out address memory for returning the second VTR from its record mode back to its playback mode.

Abstract: Abstract of the Disclosure In a hydraulic brake system, a housing includes  a brake master cylinder and a reservoir formed therein for containing a supply of brake fluid.  A sensor piston in contact with the pressure in the brake master cylinder is connected to an indicator piston.  The indicator piston is coaxial with a blind cylindrical indicator bore. The blind bore and indicator piston are in communication with the reservoir at a level below which the brake fluid should not be allowed to recede.  When the brake is operated, brake master cylinder pressure urges the sensor piston outward. The connected indicator piston is urged toward the blind bore. If the reservoir contains fluid, the blind bore is filled with the fluid. Fluid lock of the indicator piston therefore occurs before any appreciable indicator piston motion into the blind indicator bore. On the other hand, if the reservoir, and the communicating indicator bore, are empty, the indicator piston is enabled to enter the indicator bore by compressing air therein. Motion of the indicator piston into the indicator bore actuates an electrical switch which energizes a warning indicator. Once fully actuated, the electrical switch is mechanically latched in the on position to provide a continued warning indication until it is manually reset after replenishing the brake fluid.  In one embodiment of the invention, intermediate brake fluid levels cause the generation of momentary warning signals.

Abstract: ABSTRACT OF THE DISCLOSURE         A new building construction is intended especially but not exclusively for use in areas with "active soils", i.e. soils in which drastic dimensional changes occur with the seasons, owing principally to changes in water content.  Such soils heave considerably particularly, within the confines of the building footing, causing severe cracking of any floor laid directly thereon and possibly of the floors above.  In this new construction the lowermost floor structure is supported by one or more trusses, each of which is supported at its ends on the footing. The ends of the truss or trusses slide freely on the footings so as not to he affected by movement of the latter and are therefore clear of any direct earth movements.       The truss or trusses support vertical loads only, while the floating floor structure is arranged to withstand the horizontal forces applied by the active soil.  Any other floor structure is supported from the lowermost floor structure by means of one or more post members supported directly by the truss or trusses and in turn supporting respective beams for the other floor structure.  In this way none of the floor structures of the building is adversely affected by the soil movements.

Abstract: INTEGRATED FRONT END CIRCUIT FOR VHF RECEIVER     ABSTRACT OF THE DISCLOSURE         The present invention is an integrated front end circuit for a VHF receiver including a high frequency grounded base amplifier, a mixer having a differential type amplifier, a constant current type oscillator, and a bias circuit.  In the mixer, a resistor is inserted between common emitters of the transistors of a dif-ferential amplifier and the collector of a constant current transistor driving the differential amplifier.  In order to keep the oscillation frequency constant during a change in source voltage, there is provided a certain relation between the change in source voltage and the driving current of the oscillator by means of a bias circuit.  The col-lectors and bases of the transistors used for the high frequency amplifier, the differential amplifier and the oscillator use the same D.C. potential.  The integrated front end circuit of the invention may be used, for example, as the front end of an FM portable radio receiver, and it is very desirable for practical use because it realizes sure operation even at a low voltage.

Abstract: ABSTRACT OF THE DISCLOSURE         A liquid separating screen member is continuously oscillated, with an amplitude larger than the apertures in the screen member face, from a middle position with substantially the same speed in first and second opposite directions.  The screen member separates liquid from the suspension of finely comminuted fiber material and the liquid, which suspension is flowing in the first direction.          The oscillation prevents fiber mat build-up on the screen face during movement of the screen face either in the first or the second direction.  The amplitude of oscillation may be about one-tenth of an inch, and the frequency of oscillations may be about 6 cycles/sec. with the average speed of oscillation of the screen member in both the first and second directions about 2.4 inches per second, and the maximum speed in both directions about 3.8 inches per second.          The frequency of oscillation, which is below the natural frequency of the screen member and associated structures, is about at least two cycles per second.

Abstract: ABSTRACT OF THE DISCLOSURE                A process for treating waste foundry core and/or molding sand in a manner which upgrades these scrap streams to new sand quality for entry at the core making point.  The process consists of incrementally heating the sand as required up to temper-atures in the 1800° to 2500°F range, followed by cooling.  The degree of heating is chosen to achieve a desired lowering of acid demand value (ADV) from that which would result from heating only to conventional high temperatures, about 1500°F.  Lowering of ADV reduces the variability which would otherwise be introduced into a mixture of new and recycled sand for cores.                  Heating waste molding sand to the temperatures contemplated by the method of this invention also causes clay additives to fuse, become non-absorptive and thus eliminating the need for mechanical attrition which would otherwise be needed to remove the clay so that it would not absorb high quantities of resin in the core making process.  The inventive method also burns off resins from the sand being treated in a manner ?? which eliminates environmental pollution.
