Patent CA-2077356-A1 (CA)
Inventor: FLOTOW RICHARD A
IPC: F16D1/10
Filed: 1992-09-02
Abstract: COUPLING FOR CONNECTING SHAFTS               ABSTRACT OF THE DISCLOSURE A first shaft which is, for example, the output shaft of a clutch, is coupled to a second shaft which, for exam-ple, is the input shaft of a transmission, by a splined coupling.   The splined coupling includes a first sleeve having internal splines for splining with the first shaft and external splines for splining with the internal splines of a second sleeve which internal splines also spline with the external splines of the second shaft.  A first spring extending between the first sleeve and first shaft biases the first sleeve toward the second shaft, while a second spring extending between the first sleeve and second sleeve biases the second sleeve toward the second shaft.  In order to decouple the first shaft from the second shaft so that, for example, a clutch may be removed from a drive train without removing a transmission,  the  first and second sleeves are pushed to a retracted position, collapsing the first and second springs.  The sleeves are then held in the retracted position by a screw which extends through the sleeves and is tightened against the first shaft.  Upon re-placing or repairing the clutch, the clutch is reinstalled and a retaining screw released in order to reproject the sleeves and effect positive engagement between the output shaft of the clutch and input shaft of the transmission.

Abstract: A variable capacity type slant plate type compressor including a crank chamber, a suction chamber and a discharge chamber is disclosed. The crank chamber is linked by a first communication path to the suction chamber, and is linked by a second communication path to the discharge chamber. A first valve control mechanism is disposed within the first communication path and second valve control mechanism is disposed within the second communication path. Fluid communication between the crank and suctionchambers is controlled by the first valve control mechanism so that the suction chamber pressure is maintained at one predetermined constant value while fluid communication between the crank and discharge chambers is continuously closed. Fluid communication between the crank and discharge chambers is opened by the second valve control mechanism when the predetermined constant value of the suction chamber pressure must be increased. However, in the latter condition, fluid communication between the crank and suction chambers is continuously closed as long as the crank chamber pressure is not abnormally increased.

Title: Failsafe Limit Switch with Automatic Reset for Rolling Fire Doors
Inventor: HSIEH TSUNG W
IPC: E06B9/88
Filed: 1992-10-23
Abstract: A failsafe limit switch with automatic reset for a rolling fire door is usable together with a rolling door with a brake.          There is a movable plunger between a secured position and a triggered position which compresses a spring as it moves from its triggered position to its secured position. A movable catch between the engaged position and the released position holds the plunger in the secured position when the catch is in the engaged position under the impetus of the spring when the catch is in the released position. When the catch is in the released position, it also closes the contacts of a normally open switch; and if the catch is in the engaged  position, it allows the contacts of the switch to open. The switch is wired in series with a solenoid; the movable arm of the solenoid acts to move the plunger from the triggered position to the secured position when the solenoid is energized. A collar constrained against rotation is threadably mounted on a shaft,  the linear position of the collar with respect to the catch is a function of the angular position of the shaft. For a specific angular rotation of the shaft, the collar contacts and releases the catch.

Patent CA-2102679-A1 (CA)
Inventor: WATSON DOUGLAS R
IPC: H05B39/08
Filed: 1993-11-08
Abstract: A key touch dimmer includes a switching device through which AC line current is passed to brighten a lamp in response to a control signal generated by a microprocessor. The microprocessor receives an input indicative of the zero crossing points of the AC line current and synchronizes this input with its own internal clock circuitry to generate a firing signal for the switching device at the correct phase angle in the next half cycle of the AC line current. The dimmer has memory capability whereby the lamp, when turned back on, will brighten to a preset level. This brightening is accomplished in a gradual manner. Likewise, a turned off lamp will fade to zero brightness, with the dimmer retaining the preset brightness level. The microprocessor shuts down quickly in the event of a power outage to preserve memory. An optional display includes a plurality of LEDs for indicating light level. Other options include providing the dimmer with several keys, each of which can be adjusted to a respective preset level.
