Abstract: ABSTRACT            A coupling system for releasable coupling of one or more extra wheels to the original wheels of a vehicle comprises a cylindrical annular plate arranged to abut upon a tire edge or the like at the rim edge of the original wheel and the rim edge of the extra wheel, and of a number of locking cams fastened to the original rim and distributed in the peripheral direction of the wheels.  The cams are arranged to interlock with tightening hooks fastened to the annular plate.  The extra wheel can be attached to the annular plate by spot welding.  In the annular plate outwardly open cut-outs are made opposite each tightening hook.  When mounting the annular plate with the attached extra wheel the cutouts are  led in over the locking cam fastened to the original rim and then the extra wheel and the annular plate are tur-ned in the peripheral direction of the wheels whilst the edge of the annular plate abuts the tire edge on the origi-nal rim.  When the annular plate is turned sufficiently in the peripheral direction of the wheels such that the tigh-tening devices are opposite the locking cams, the tighte-ning devices are tightened in engagement with the locking cams.

Abstract: METER TO PRINTER COUPLING CIRCUIT          Abstract of the Disclosure A coupling circuit for coupling a printer to a meter permits single line digital printout of metered data in response to operation of a manual switch.  Printing is initiated when a bistable occupies one state and a print command is produced by the meter indicating that a stable voltage has been detected by the meter.  That bistable state is produced by manual operation of a switch, such operation also triggering a hold unit within the meter to hold the stable reading for a period permitting data to be shifted to the printer and for printing to occur.  While printing and paper advance is under way, the printer delivers a busy signal to the bistable to change its state.  Subsequent state reversal can then only take place on manually operating the switch once again.  In this way only a single line of print is achieved on command.  The particular logic arrangement described prevents erroneous printing of lines of data in response to switch contact bounce.                             - i -

Abstract: INTERROGATING SYSTEM FOR REMOTELY   MONITORING TIRE AIR PRESSURE      Abstract:             The air pressure in a tire is monitored by transmitting an electromagnetic interrogating signal (specifically a radio frequency signal) from the vehicle to a passive transponder, affixed to the wheel on which the tire is mounted, in communication with the air pressure within the tire.  When the pressure is normal, a semiconductor diode (24) and an antenna (24a) in the transponder will be shielded (21) from radiation and therefore no response will be made to the received interrogating signal.  On the other hand, abnormal  air pressure in the tire causes the antenna to become unshielded and exposed to the interrogating signal radiated from the transmitter (31-36), whereupon the diode reacts to the received signal and develops there-from a response signal which is retransmitted from the antenna and includes, among other signal components, the second harmonic of the interrogating signal.  A receiver (31,37-42), tuned to the second harmonic, produces from the response signal an indication (preferably on the vehicle's dashboard, that the sensed tire air pressure is abnormal.

Abstract: PARALLEL CYLINDER INTERNAL COMBUSTION ENGINE          ABSTRACT OF THE DISCLOSURE          The  engine  disclosed  herein  comprises a number  of  pairs  of pistons, the two pistons in each pair acting in unison. The pairs are  arranged  parallel  to each  other,  and  the   pistons  are positioned parallel to and in a circle around the mainshaft which has  a cam lobe located at a convenient part of the mainshaft and encircling  the  mainshaft.  The cam lobe has  opposite  surfaces which  have  sinusoidal rises and dips  and are in  contact  with pairs of bearings attached to connecting rods.  The bearings  are on opposite sides of the cam lobe,  and at one time are driven in one  direction  by one of the two pistons in each pair  and   at another  time  in the opposite direction by the other  piston  in that pair,  the two pistons of that pair being connected to  each other  by  the  same connecting rod carrying the  bearings  which press  against the cam lobe.  The pressure exerted first  by  one bearing  and then by the opposite bearing in concert with similar thrusts  from  other  pairs of bearings  and  pistons,  causes  a steady, even rotation of the shaft on its linear axis. The action of  the  pistons  and  bearings is arranged  and  timed  so  that pressure against the surface of the cam lobe exerts vector forces against the curved surface of the cam lobe to effect rotation  of the main shaft. Centerline thrust of the bearings against the cam surface  and special design of the cam surface to avoid  friction or  binding between the bearings and the cam are special features of  this engine.  The pistons may be driven by combustion  fuels, including  gasoline,  diesel,  etc.,  and may also be adapted  to steam operation.

Abstract: ABSTRACT      A method and apparatus are disclosed for transferring blanks, plastic parisons or other articles to be molded in a sealed cavity.  One embodiment includes mold sections which are closeable along a first axis to form a mold cavity and which are movable along a second axis from a first station where the mold sections may receive a mold-able blank to a second station where the blank may be molded under pressure.  Optional biasing means may be included to hold the mold sections sufficiently close together to hold the blank in the mold cavity as the mold sections move from the first station to the second station. A clamp, or other pressure applying means, exerts a final closing pressure on the mold sections at the second station for molding the blank under pressure.  The clamp is sta-tionary in relation to the first and second stations so that the mold sections can move relative to the clamp along the second axis.  In another embodiment the method includes the steps of transporting mold sections generally along a first axis to a first station; moving the mold sections generally along a second axis while at the first station to close the molds around a blank sufficiently to encapsu-late the blank in an interior cavity formed by the mold sections; transporting the blank in the mold cavity to a second station by moving the closed mold sections along said first axis; and exerting a force on the mold sections at the second station to form a proper seal for molding, the force being exerted from a source which is stationary in relation to the first and second stations.
