Abstract: RECONSTITUTING APPLIANCE    FOR FROZEN POT PIE AND METHOD OF USING SAME                 Abstract of Invention A combination of a mass produced frozen entree type foodstuff, such as a pot pie, formed from a precooked, lossy material filler food having a preselected depth and covered with a layer of uncooked dough and an appliance for trans-porting and reconstituting this pot pie in a microwave oven wherein the appliance comprises a dish-shaped receptacle formed of a microwave impervious foil material with a cavity for the foodstuff and a peripheral rim whereby the filler material within the cavity is shielded from direct microwave exposure except through the dough layer and a flat, self-sustaining generally rigid microwave susceptor sheet with an outer shape generally matching the preselected shape of the rim on the receptacle wherein the susceptor sheet is sup-ported on the dough in parallel, heat conducting relation-ship with the upper surface of the dough and is spaced from the rim by the dough. The susceptor sheet includes a thin metallized layer of plastic film laminated to a paperboard. A method of employing this appliance in combination with the pot pie includes passing microwave energy for a preselected time through the dough layer and then into the filler mate-rial while the microwave impervious foil material shields the filler material from other microwave energy  during which preselected time the filler food is heated and the dough layer is baked and, then, covering the shielded food material with the thin microwave heatable susceptor sheet and passing microwave energy through the susceptor sheet for a time necessary to brown the upper surface of the dough while allowing microwave energy to pass through the dough layer into the shielded filler material.

Title: Belt tensioner with releasable belt load damping
Inventor: KOMOROWSKI JACEK
IPC: F16H7/08
Filed: 1988-07-29
Granted: 1992-07-07
Abstract: BELT TENSIONER WITH RELEASABLE BELT LEAD DAMPING            ABSTRACT OF THE DISCLOSURE           A belt tensioner having a sleeve bearing pivotally mounting a pivoted structure on a fixed structure for spring pressed movement between first and second positions.  The sleeve bearing is larger than and surrounds a ball bearing assembly rotatably mounting a pulley on the pivoted structure.  The pulley has a cantilevered rim which axially overlaps and annularly surrounds the sleeve bearing.  One of the structures and the sleeve bearing have slidably interengaging surfaces which are compressed together by the belt load force in the pivoted structure and the reactionary force acting in the fixed structure so as to provide a damping torque resistance to the pivotal movement of the pivoted structure which prevents movements resulting from dynamic changes in the belt load force within a range.  The arrangement is such that independent vibrational forces instantaneously release the damping torque resistance to permit instantaneous movements otherwise prevented.

Title: Brake assurance circuit to preserve proper locomotive  operating status
Inventor: RUMSEY STEVEN C
IPC: B60T13/66
Filed: 1989-03-06
Granted: 1993-12-14
Abstract: ABSTRACT OF THE INVENTION      A brake assurance circuit via which a magnet valve device is deenergized to exhaust brake pipe pressure independently of the locomotive brake valve device and thereby apply braking any time the proper operating status of the locomotive brake valve is changed after the locomotive is underway.  A pressure switch responsive to the cut-in and cut-out setting of the manual selector valve associated with the brake valve senses the locomotive status and connects one of two possible circuits to the magnet valve device in parallel with a primary circuit having a speed responsive switch.  Once locomotive movement is underway, the primary circuit drops out and the effective circuit selected by the pressure switch maintains the magnet valve energized provided the selected pressure switch setting is not changed.  Should the pressure switch setting be changed, all power is cut off from the magnet valve and cannot be reapplied until the locomotive comes to a complete halt to allow the speed responsive switch to reset and restore power via the primary circuit.

Title: Automatic servo gain calibration system for a disk drive
Inventor: WATT CHARLES R
IPC: G11B21/10
Filed: 1989-06-08
Granted: 1993-06-08
Abstract: Abstract of the Disclosure A method for automatically calibrating gain parameters of a servo control including a track position detector for a computer disk drive.  The method generally comprises the step of encoding AB bursts on at least one special calibration track of a disk surface in accordance with a known off center pattern signal having a preselected frequency.  Servo correction number information is also encoded on the calibration track to compensate for the off center pattern of the AB bursts. A digital signal processing technique is performed on a correction signal derived from the AB bursts and servo correction number information to detect a residual signal at the preselected frequency of the off center pattern signal.  The gain of the track position detector is thereafter adjusted to minimize the magnitude of the residual signal.
