Abstract: Angle measuring apparatus including a disc having a circular track of marks on one surface concentric with the disc, such disc being rotated about its axis. A mark sensor located adjacent the disc surface detects each mark and generates a signal as it passes thereby. A pair of angle-input means are located adjacent the disc for defining the angle to be measured. Reference means rotate with the disc and interact with each input-means to generate a reference signal each time the reference means passes thereby. Control circuitry counts the number of mark signals occurring between selected reference signals and from such count, the defined angle can be accurately computed.

The forward corners of the bucket, near the discharge chute, are equipped with downward opening hooks. The hoisting suspension includes flexible forward support members which releasably engage the hooks, and flexible rearward support members which support the rear of the bucket. The forward support members are attached to a cross beam which is maintained in a horizontal position above the bucket in such a manner that the forward members lie substantially exterior of the space vertically above the bucket.

Abstract: A combination heat transfer panel and wall shield for use with stoves and other radiant heaters. The device comprises a case housing two parallel, spaced curtains defining first and second convection chambers. The case is adapted for location either against, or in spaced relation to a structural wall behind a radiant heater. It is formed with a large central opening permitting entrance of radiant energy from the stove, a cold air inlet communicating with the convection chambers either at the lower end of the case or at the sides, and a hot air exhaust communicating with the upper end of the convection chambers. The outermost curtain may be constructed for adjustment between positions in which it absorbs or reflects radiant energy, as desired.

Abstract: The apparatus comprises a wheel-mounted frame on which engine driven hydraulic pumps are mounted to provide hydraulic power. Extending from the side of the frame is a live deck for transporting logs transverse to their length. A longitudinal conveyor receives the logs from the live deck and transports the logs to a retractable stop to establish the length of a firewood block. A saw adapted to transversely cut the log is arranged to be lowered to cut the block from the log. A guard encloses the saw and supports clamps that clamp the log on each side of the saw during cutting. The retractable stop is retracted from the log end as the guard clamps the log for cutting. Following cutting the cut block is directed to a centering device which centers the block relative to a hydraulic actuated ram and fixed splitter blades. The block is split when forced across the splitter blades by the ram. A kicker rejects log remnants to a reject conveyor. Unsuitable blocks are rejected to the reject conveyor.

Abstract: A chain saw antipinch guard arm including an arm attached pivotally to a chain saw, the arm being movable in a plane substantially parallel to the plane of the blade. A handle extends upwardly from the arm and is pivotal therewith. The arm may be manipulated by the saw operator with a scissor-like action with respect to the blade and may be used for applying a force to the underside of a piece being sawn, thereby preventing pinching of the blade, while at the same time protecting the operator from injury.
