Abstract: A wireless data display system has a receiver/display unit tuned to the same frequency as a sensor/transmitter unit for monitoring wheel rotation for a vehicle such as a bicycle. The two units are preferably battery powered, and their circuits are designed for low power consumption. Both units have directed antennas positioned in alignment with each other. The receiver includes a tunable antenna to enhance signal reception and reduce sensitivity to a transmitter of an adjacent system, as well as filter and latch circuitry to reduce interference from EMI or RFI or from adjacent operation of a similar transmitter/receiver pair.

Abstract: A high current carrying connector plug and receptacle are disclosed. The plug comprises a body of electrical insulating material with plurality of shaped passages extending therethrough, electrical conductors having a flat blade contact portion, a stop means and a hollowed cylindrical portion for receiving and securing a current carrying electrical cable. The passages include stop engaging means. A retainer means engages the flat bladed portion preventing axial movement of the conductors in the plug body.The receptacle comprises a body of electrical insulating material having shaped passages therethrough, electrically conductive conductor contact engaging assemblies in each passage at the front face of the body. The contact assemblies comprise movable jaws having a front contact engaging portion and a rear coupler engaging portion and a spring retainer means converging at least one pair of jaws.

Abstract: A spacer tray 2 for containers 32 is formed of a moldable sheet material and is shaped to provide a plurality of container-bottom receptacles 4. Each container-bottom receptacle 4 is shaped to receive at least a part of a bottom portion of a container 32. A container spacer wall 30 is located between each pair of adjacent container-bottom receptacles 4 to maintain bottom portions of containers seated in the receptacles spaced apart from one another. The spacer tray includes a plurality of container-loading-guide-pin caps 36 which permit end portions of container-loading guide pins 78--from a high-speed spacer-tray loading machine, for example--to project into and fit within the interiors of the caps for locating the spacer tray 2 and for reinforcing the caps for guiding bottom portions of containers 32 into container-bottom receptacles 4 during loading of the spacer tray.

Abstract: A forceps for use in orthopedic surgical procedures having readily interchangeable tip elements and a reversible ratchet mechanism, for controlling the tip elements. A variety of tips for compression and distraction are provided. The ratchet mechanism permits controlled increments of force to be applied to the tips.

Abstract: Electronic data processing system for preparation of electronically filed tax returns and authorization and payment of refunds based on the data supplied in those returns. Electronic data processing programs are provided for creating an electronic tax return that is filed with a tax collecting authority. At the same time as the electronic tax return is created a loan application is processed to create an electronic deposit/loan account for the tax filer at an authorized credit institution. As early as the day after completion of the tax return and loan application, the tax filer receives initial refund payment from the loan account. The authorized credit institution electronically files the electronic tax return with the tax collecting authority which processes the return and transfers by electronic fund transfer the refund amount to the deposit/loan account at the authorized credit institution. Any refund in excess of the initial refund payment is then forwarded to the tax filer.

Abstract: An apparatus for noninvasive determination of constituent concentrations utilizing light wave absorption measurements and methods for processing signals generated by such measurements.

Abstract: The resistance of an inductive load is measured by connecting an inductor to the load and applying a pulse of energy to the load and the inductor. The voltage across the inductor is monitored and the load voltage and current are measured when the inductor voltage passes through zero. The ratio of the voltage and current at the instant of zero crossing is equal to the load resistance value. An apparatus for performing this method is disclosed.

Abstract: The present process results in a surface which is impermeable and resistant to the action of chemical substances and heat. Natural stones such as marble, travertine, granite and structural and ornamental works made out of these stones are protected from atmospheric and chemical process of degradation by a novel method of sanding down the surface with an industrial diamond abrasive to open up the pores of these solids; rinsing with water, removing water with a chemical solvent and wiping with a tack cloth to remove microchips. A protective mixture in the form of a moisture-cured polyurethane is then applied to the surface of the stones. The moisture-cured polyurethane acts as a sealant for the pores of the stones and as a chemical polish on the surface of the stones, such sealant being impermeable and resistant to the action of stains produced by chemical substances.
