Abstract: RESERVE RESERVOIR COVER     ABSTRACT OF THE DISCLOSURE        A cover for a retention chamber in a master cylinder reservoir which will permit a probe to pass through a tab and pressurize a piston in a pressuriz-ing chamber with a test fluid under pressure.  This test fluid will allow an operator to visually inspect the master cylinder for fluid failures at various pressures.  In the normal operation, the tab of the cover will allow fluid to flow from a supply chamber into the retention chamber.  However, during a brake application when fluid is transmitted through the compensator port as the pressurizing piston moves past the compensator port, the tab will prevent this fluid from being squirted into the supply reservoir.  This will assure thata minimum quantity of fluid is always present in the retention chamber to operate the brake system even though a low fluid level indicator in the supply chamber presents a failure warning signal to the operator.

Abstract: LOW TIRE PRESSURE WARNING SYSTEM    WITH MECHANICAL LATCHING          Abstract of the Disclosure An air switch senses abnormally low pressure in a tire and provides a pneumatic signal to an actuator which moves a magnet from a normal position to a warning position.  An electrical detection system senses that the magnet is in a warning position and provides a low pressure warning signal to the vehicle operator.          The actuator contains a mechanical latch to assure that the magnet remains in a warning position even if the pneumatic signal should cease.  A reset feature allows the latch to be disengaged to return the actuating mechanism to normal condition when proper tire inflation pressure has been restored.

Abstract: S P E C I F I C A T I O N                        LOCK ASSEMBLY                  ABSTRACT OF THE DISCLOSURE     An improved lock assembly of the wafer tumbler type is provided which includes a plurality of wafer-type tumblers mounted in a cylindrical plug or carrier at spaced positions along the axis of the carrier.  The tumblers are slidable radially in the carrier to project, beyond the carrier into restricted annular pockets in the inner surface of the housing, so as to hold the lock in a locked condition.  Only when the proper key is inserted into the plug are all the tumblers drawn within the confines of the plug by the key, allowing the key to turn the plug and to operate the latch or bolt controlled by the lock.  The lock of the invention is constructed so that each tumbler is of a two-piece construction to include a key-follower member which may be engaged with the corresponding tumbler at a selected position along its length, with the key followers assuming different positions with respect to the corresponding tumblers, so that only when a par-ticular key is inserted into the plug, will all the tumblers be drawn within the confines of the plug, allowing the plug to be turned to the unlocking position.  The key followers are held in engagement with the respective tumblers during normal operation of the lock.  However, the plug can be turned to a re-setting position by the particular key, at which position the followers are re-leased.  Then, a new key may be inserted into the lock to cause the key followers to assume different relative positions with respect to the various tumblers in conformity with the new key.  There-after, when the plug is turned back to the normal operating posi-tion, the key followers are locked into engagement with the tumb-lers at the new position, and the lock is then conditioned for operation with the new key, instead of the former key.  Means is provided to prevent the plug from being turned back from its re-set position to its normal operating position unless the key is fully inserted into the lock, to prevent partial settings of the key followers.  The lock also includes a pick bar which engages the tumblers whenever the plug is turned from a reference position to prevent movement of the tumblers at any angular position of the plug except the reference position, so that the lock is ren-dered virtually pick-proof.

Abstract: ABSTRACT         A copying machine wherein successive strip-shaped portions of an original are imaged onto a moving photosensitive carrier by a system which is mounted in part on a reciprocable carriage and includes one or more incandescent or fluorescent lamps and a mask having an elongated aperture through which light issuing from the lamp or lamps and impinging upon successive strip-shaped portions of the original passes to the photosensitive carrier.  The mask can be installed in the path of modulated light between the lamp or lamps and the original or between the original and the carrier. The longer sides of the aperture are flanked by crenellated marginal portions of the mask so that the aperture is subdivided into a plur-ality of elongated neighboring sections which extend in the direc-tion of movement of the carriage.  The lens of the imaging system images the neighboring sections of the aperture onto the carrier in such a way that the images overlap, at least in part. This prevents the development (or reduces the sharpness) of ripples which normally develop on the copy as a result of unequal illumination of succes-sive strip-shaped portions of the original, primarily because the intensity of light varies owing to the fact that the lamp or lamps are in circuit with a source of alternating current.

Abstract: FEED-FORWARD AMPLIFIER ABSTRACT A high-precision amplifier employs a feed-forward technique to provide a first order correction of amplifier distortion. A second amplifier is utilized to sense the base-to-emitter distortion of a main amplifier and develop an error output which is injected into an output node to provide cancellation of distortion from the output of the main amplifier. The feed-forward distortion-correction technique is particularly applicable to high-precision wideband differential amplifiers; however, the technique may be used in other amplifiers as well.
