Abstract: ABSTRACT            Self-Checking Computer Circuitry Circuitry for a fault-tolerant computer is disclosed which circuitry is constructed in two identical halves. Each half, by itself, is not a functionally-complete circuit, however, the two identical halves can be connected together to provide a functionally-complete circuit.  Each of the two circuit halves is considerably less complex than a functionally-complete circuit yet, when connected together, the two halves provide fault detection capabilities equivalent to a computer system in which the outputs of two functionally-complete, redundant circuits are compared to detect faults.    In particular, each inventive circuit half contains a complete data processing and control unit but only one half of the memory which is necessary for a functionally-complete unit.  The processing units on each circuit half operate simultaneously on identical data and the same address information is provided to the memories on each circuit half.    To provide error detection, address information and data sent from each control unit to its associated memory is acompared between circuit halves.  In addition, information provided to the circuits over an external bus or generated by the control unit is encoded with an error-detecting code.

Abstract: ABSTRACT OF THE DISCLOSURE         A solar heating system characterized by a fixed base assembly and a movable collector assembly coupled to the base assembly such that it can move between a closed position and an heating position.  The base assembly and is designed to fit an opening provided in an enclosure.  The collector assembly is hinged to the base assembly such that it covers the base assembly when in the closed position and such that it is angled towards the sun when in the open position.  Cool air is drawn from within the enclosure through ducts, and is heated within the collector assembly and returned to the enclosure.

Abstract: PNEUMATIC IMPACT TOOL     ABSTRACT OF THE DISCLOSURE           A pneumatic impact tool wherein a two-stage piston is reciprocable in the two-stage chamber of a cylinder.  The tool which is to penetrate into a bone is mounted in the front portion of the cylinder and the piston strikes against such front portion in response to admission of compressed air against its rear end face,   A relatively small annular shoulder of the piston faces forwardly and is continuously acted upon by compressed air.  When the piston approaches or reaches the end of its forward stroke and rebounds from the front end portion of the cylinder, it seals the source of compressed air from its rear end face so that the action of compressed air upon the shoulder suffices to propel the piston rearwardly against the rear end portion of the cylinder at which time the piston reestablishes a path for the flow of compressed air against its rear end face so that it is propelled forwardly against the front end portion of the cylinder.

Abstract: ABSTRACT A rotation ring barker having a stator and a rotor with an opening for lengthwise feeding of a log and which is associated with a number of working tools, each actuated by a spring mechanism normally striving to maintain the tool yieldingly urged against a log passing through the rotor for removing the bark from the log. If necessary, the individual tools are jointly movable in a direction outwardly from the log against the action of said spring mechanism. Positioned between the rotor and stator is a ring element which is rotatably mounted on the rotor and normally operating at the same speed as the rotor. The ring is connected with the drive shaft or drive member of at least one motor mounted on the rotor; the stator has a braking device adapted to reduce, when need arises, the speed of the ring in relation to the rotor speed, while providing for relative movement between said rotor and said ring so that the motor transmits to the working tool and/or the spring mechanism a force overcoming the pressure of the spring mechanism and causing the tool to swing outwardly away from the rotor centre.
