Patent CA-2051776-A1 (CA)
Inventor: HAID RAYMOND F
IPC: E01C19/00
Filed: 1991-09-18
Abstract: A power screed for smoothing freshly poured concrete and a method of operating the screed is described.  The screed has adjustable vertical support means to account for uneveness in the supporting surface.  The support means are located near each side of the screed and are controlled by hydraulic motors. The screed can be adjusted manually and/or automatically through the use of an external laser source.  When concrete is poured, it is roughly smoothed by rakes or similar tools.  The screed is then advanced over the concrete with the lowest level of the screed determining the level of the surface of the concrete.  Where the supporting surface upon which the concrete is poured is uneven, the screed can be raised or lowered to ensure that the upper surface of the concrete is level.  The support means are each composed of two screw jacks mounted on a ski.  As the screed advances through the concrete, the support means leaves a track in the concrete which must be smoothed and filled manually.  Presently, the level of a screed is controlled by bulkheads located at either side of the screed.  The bulkheads must be installed in such a manner that an upper level of th bulkheads corresponds to an upper level of the finished concrete.  With the present invention, the bulkheads can be eliminated.

Title: Pulse signal averaging circuit with sampling interval dependent on pulse amplitude
Inventor: WILFORD TIMOTHY W J
IPC: G01R19/00
Filed: 1992-05-05
Abstract: An integrating sample-and-hold circuit which synchronously determines the mean amplitude of periodic pulses and waveforms is provided.  A periodic input signal is simultaneously applied to a buffer amplifier, a comparator, and a threshold detector.  The threshold detector which consists of a peak hold circuit and a voltage divider provides a threshold voltage which equals a predetermined fraction of the peak voltage of the input signal.  The threshold voltage and the input signal are compared by the comparator which provides a sampling command when the input signal exceeds  the threshold voltage.  The sampling command operates a switch which connects the output of the buffer amplifier to an integrating sample-and-hold amplifier.  The buffered input signal is integrated during the sampling interval, and the integrated mean voltage of the input signal is held until the sampling of the next cycle.

Title: Apparatus for producing slices with biased spring-loaded feed mechanism
Inventor: CIMPERMAN FREDERICK J
IPC: B26D3/11
Filed: 1992-10-16
Abstract: Abstract of the Disclosure An apparatus for slicing objects, such as potatoes, with a rotatably mounted knife assembly. Objects (such as potatoes) to be sliced are conveyed downward toward the knife assembly between a gripper chain and a feed chain. A pair of springs provide a biasing force which urges the chains together, thereby ensuring that the conveyed potatoes are fed positively and uniformly toward the knife assembly. Preferably, two feed rolls having teeth are mounted between the lower ends of the chains and the knife assembly (each feed roll at the end of a rotating, slidable shaft). The teeth of the rotating feed rolls grip each potato conveyed against them by the chains, and force each such potato downward against the rotating knife assembly. Preferably, a support and retaining plate is fixedly mounted to the feed mechanism to constrain vertical movement of the feed rolls as they rotate with a potato gripped between them.
