Patent CA-2067007-C (CA)
Title: Apparatus for equipment unit protection switching
Inventor: BROCKWAY ROBERT C
IPC: H01H35/00
Filed: 1992-04-24
Granted: 1997-11-04
Abstract: An equipment unit protection switch from an in-service equipment unit to a standby equipment unit is realized prior to any movement of the active equipment unit about to be removed from an equipment frame in which it is inserted. This is achieved by advantageously incorporating apparatus for generating an equipment unit removal indication signal that enables a controller to anticipate the removal of the equipment unit from the equipment frame. To this end, the equipment units employ an equipment unit latch and an associated switch to generate the equipment removal indication signal. Initial movement of the latch causes the equipment unit removal indication signal to be generated prior to any movement of the equipment unit in the frame in which it is inserted. (FIG. 4)

Abstract: A pin tenter clamp for a tenter apparatus has a clamp base on which tenter pins are disposed.   The clamp base is provided with  a hinge about which a clamp top plate  is pivotable.  A resilient, elastomeric clamp pad is disposed on a side of the clamp top plate facing the clamp base and tenter pins.  The clamp top plate is biased away from the clamp base to open the pin tenter clamp.  Between the clamp top plate and clamp base is a stripper plate having openings through which the tenter pins may extend when the pin tenter clamp is closed.          The stripper plate also has a resilient, elastomeric clamp pad having openings aligned with those in the stripper plate.  When the pin tenter clamp is open, the stripper plate resides above the tenter pins.  In use on a tenter apparatus, the present pin tenter clamp first holds the fabric to be stretched between the resilient, elastomeric clamp pads before the tenter pins may extend therethrough.   As the pin tenter clamp is gradually opened after the stretching of the fabric,  the resilient, elastomeric clamp pads hold the fabric while the tenter pins are withdrawn, and release the fabric only after this has taken place.

Granted: 1996-12-03
Abstract: A valve mechanism for a hydrostatic transmission having a variable displacement pump and a motor in fluid communication with each other via a closed-loop fluid system.  The valve mechanism provides pressure relief and a wide neutral feature within a predetermined range of movement about a zero displacement or neutral position of the pump.  The valve mechanism is variably controlled by and in coordination with the movement of the displacement pump control mechanism from a fully open position through a fully closed position, such that as the pump is shifted into and out of neutral from both a forward and reverse displacement position, the valve mechanism is moved therewith.  The valve mechanism constitutes a ring surrounding the conduit and is responsive to the pump control mechanism so as to move concentrically therewith. The ring valve includes bores selectively communicating with respective bores in the fluid system such that the fluid system is in selective communication with a cavity formed in the housing. The bores provide a metered leak path from the fluid system within 3° of neutral in either the forward or reverse displacement positions upon actuation of the pump control mechanism into the same displacement position so as to reduce the pressure within the fluid system during engagement of the transmission.  Movement beyond 3° completely closes the valve such that full pressure may be developed within the fluid system.

Title: Vacuum cleaner with illuminated belt view
Inventor: SEPKE ARNOLD L
IPC: A47L9/30
Filed: 1993-10-20
Granted: 1996-04-09
Abstract: An illuminated belt view for a vacuum cleaner wherein light is transmitted, via a light pipe, from a remote light source to an area directly underneath a transparent belt view window.  The transparent belt view window is formed in the vacuum cleaner hood to allow the operator to observe the operating condition of the belt therein, the belt being operable to transfer rotational motion from a motor output shaft to a rotary brush.  Illumination of the belt in the area of the belt view window allows the belt and the operating condition thereof to be observed during low ambient light conditions.  Use of light from the light source, which is primarily a headlight, removes the need for an independent light source for the belt view window without significantly decreasing the amount of light which is transmitted to the area in front of the machine.  Also, use of a single light source for indicator illumination and headlight functions reduces the energy necessary to operate the vacuum cleaner, the heat produced by the vacuum cleaner, and manufacturing and maintenance costs by minimizing the number of light bulbs to be installed and replaced.

Abstract: An electrical outlet box is formed from side plates and a U-shaped plate forming top, bottom and rear walls. The side plate has bosses, projecting outwardly from the box to ensure that the box is uniformly spaced from a vertical surface, for example the side of a stud. To facilitate mounting of the box to a stud, at least one boss has an aperture therein for receiving a screw or other fastener. Preferably, this aperture has an axis angled so that the axis passes through the front opening of a box. The bosses with apertures can include planar central portions for receiving a screw head and further can have an outer portion to the aperture for receiving part of a screw head to minimize protrusion of the screw head into the box. The screw head is then recessed away from the interior of the box to prevent shorting of electrical context, and as it is located in a boss contacting the stud or other surface, unwanted distortion of the side plate is avoided.
