Granted: 1995-07-04
Abstract: An apparatus for performing Trendelenburg therapy and reverse Trendelenburg therapy includes an intermediate frame carried above a base frame by an inner cross-riser pivotally connected to an outer cross-riser.  One end of the outer cross-riser is pivotally connected to the base frame, and the opposite end of the outer cross-riser is rotatably and translatably connected to the intermediate frame via a cam and cam follower arrangement in which the cam follower rides on a wear plate.  One end of the inner cross-riser is pivotally connected to the intermediate frame, and the opposite end of the inner cross-riser is both rotatably and translatably connected to the base frame via a cam and cam follower arrangement in which the follower rolls against a lower wear plate.  A pivotable Trendelenburg linkage is carried on the end of the inner cross-riser connected to the intermediate frame, and a pivotable reverse Trendelenburg linkage is carried on the end of the outer cross-riser rotatably and translatably connected to the intermediate frame.  Dual acting hydraulic cylinders power the raising and lowering of the intermediate frame by effecting a scissor movement between the inner cross-riser and outer cross-riser.  Single acting hydraulic cylinders power the pivoting movement of the Trendelenburg linkage.  Similarly, single acting hydraulic cylinders power the pivoting movement of the reverse Trendelenburg linkage.

Patent CA-2057650-C (CA)
Inventor: WAGGAMON DENNIS W
IPC: E05F15/00
Filed: 1991-12-13
Granted: 1998-10-13
Abstract: The light beam in an obstruction detector is coded into packets of pulses by a transmitter.  When the light beam is received, the receiver recovers the code signal, and supplies it to a code detection circuit.  To detect the code, the circuit supplies the code signal and a delayed version of the code signal to an "exclusive or" gate.  If the code is present, the gate produces a pulsed output resulting in a "safe" signal being sent to a door opener control circuit.  If no code is present, the gate produces a relatively constant output resulting in an "unsafe" signal being sent to the door opener circuit.  The "unsafe" signal is produced not only in response to obstructions, but also, in response to errors and malfunctions in the wiring to the transmitter and receiver and in the transmitter and receiver themselves.

Abstract: A method and a machine are described for drying of fibrous web, especially suitable for high speed machines producing printing papers. High drying rates are obtained by subsequently pressing the two surfaces of wet web (5) onto two large diameter dryer cylinders (1, 2) heated to between 100 and 150°C. In the first nip, the web (5) is pressed on the dryer cylinder (1) by a felted press roll (3), while an unfelted smooth roll (4) is used to press the web (5) on the second dryer (2). Drying rates obtained when practicing the invention are substantially greater than those found in conventional dryer sections. The product obtained according to this method is 30 % stronger than the conventionally dried uncalendered paper, and without calendering has a smoothness and gloss similar to those of calendered conventional papers.

Abstract: The presence of decay is determined in wood by testing a sample.  The wood tested may be standing timber, cut timber or when coated in building structures. The testing occurs in very short time intervals so that tests can be carried out on timber in mills and the like. The method of testing includes heating a portion of a wood sample at a temperature in the range of about 220 to 350°C to evaporate analytes from the wood, conveying the analytes in a sample gas flow into an ionizing chamber of an ion  mobility spectrometer detector, ionizing the analytes within the ionizing chamber at a temperature in the range of about 220 to 350°C, generating an ion drift time signature in the detector, and comparing the signature with predetermined signatures representing decay in wood.

Granted: 1999-04-20
Abstract: The enclosure  assembly, being particularly but not exclusively conceived for use over electric cable splices, comprises a sleeve of an elastomer material,  a support whereover the sleeve is  fitted in a condition of elastic expansion, said sleeve being adapted to shrink around the elongate cylindrical objects upon removal of the support. The support comprises two substantially cylindrical, tubular bodies having ends  abutted  coaxially  with  each  other  in  mutual  continuation relationship;  the abutted ends  are disposed at substantially inward locations  of  the  sleeve  longitudinal extension. Thus, the  support removal can begin from a predetermined internal region of the sleeve; the sleeve starts shrinking over the splice within said internal region, and  any  axial deformations  in  the  sleeve  would  leave  the  sleeve positioning relatively to said predetermined internal region unaffected.

Abstract: The present invention features an apparatus and method for extending, position sensing and folding the ties of a tie bag into the body of the bag. The apparatus and method of the invention accomplish the position sensing end folding of the ties as the webbing of the bag is rapidly moving. The ties are first extended and then folded within the web on-the-fly. The ties of the flexible web are caused to pass between two extension plates, in which respective air nozzles are located. Air is transversely passed over the upper and lower webbing surfaces via the nozzles. In so doing, the flexible ties are caused to flatten, smooth and extend perpendicularly to the direction of travel of the web. The air under pressure also prevents the ties from contacting the walls of the plates. The extended ties are now oriented so as to be acceptable to both the sizing and folding operations.
