Abstract: EMERGENCY EXIT DOOR LATCH WITH HYDRAULIC RETARDATION OF BOLT RETRACTION           Abstract of the Invention An emergency exit door latch includes a pivoted bolt which pivots into registration with a keeper and is urged in the projected position by a spring biased plunger.  The spring biased plunger is retained within a hydraulic cylinder.  Hydraulic lines connect the portion of the hydraulic cylinder in front of the plunger to the portion behind the plunger through a throttling means.  Upon pressing against the door, the swinging urges the plunger rearwardly so as to force fluid in the rear portion of the hydraulic cylinder through the line and the throttling means to the front portion of the hydraulic cylinder thereby allowing the bolt to slowly retract as the fluid is throttled.           Preferably, a push bar is provided having a detent means thereon which locks the bolt in it projected position.  Upon pressing the push bar, the bolt is released so that it can be slowly retracted as pressure is placed on the door.           Preferably, there is an emergency release system which allows rapid transfer of fluid from the rear of the piston to the front of the piston upon the occurrence of an emergency condition such as tripping of a fire alarm or smoke alarm.  This emergency system allows the hydraulic fluid to bypass the throttling device which generally retards retraction of the bolt.           An alarm system is connected to the latch and sounds whenever the latch is operated so as to alert personnel within the building that someone is trying to open the emergency door without authorization.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for sharpening scissors and similar two bladed cutting implements in which both blades  are sharpened simultaneously with the scissors kept in the closed condition.  The apparatus includes a hollow housing containing a pair of blade sharpeners, at least one of which is mounted for movement towards and away from the other and is spring influenced towards the other.  The or each movable sharpener is carried at a front end of a elongate member which extends rearwardly into the housing and is movable about an axis located at or adjacent its rear end.  Sharpening is effected by passing the closed scissors between the two sharpeners so that the cutting edge of each blade is treated by a respective one of the sharpeners and each sharpener serves to remove material simultaneously from the cutting edge of one blade and the back edge of the other blade.

Abstract: ABSTRACT   The error rate performance of a digital radio system which is deteriorated due to inband interference components can be effectively improved by adopting the present digital signal reception technique.   A narrow band band-elimination filter removes the interference, and after the digital signal is regenerated, the spectrum, which is removed by said band-elimination filter, is recovered from the regenerated digital signal.  The recovered digital signal is added to the original one, and is applied to the regenerator.  Thus, even if there is an interference component in the same pass-band as the digital signal, it can be removed and the digital signal re-obtained without the interference component.

Abstract: Abstract of the Disclosure Electro-optical system to test for bilirubin presence and concentration in blood samples.  An optical system for transilluminating the blood sample with a beam divider to create parallel optical paths after transmission through the sample.  A different band pass filter in each of the parallel paths provides transmitted light at two specific wavelengths such that the effect of hemoglobin, in the sample, on the compared light intensities along the parallel paths is eliminated.          A gradient density filter in one path is movable, in response to an imbalance, to a position at which intensities of light transmitted along the parallel paths are equal.  The filter position is correlated to a reading of bilirubin concentration.          An automated sample handling system receives samples, moves them into operative position in the optical system and signals the optical system to function, and returns the sample for removal.

Abstract: ABSTRACT            FAULT DETECTING SENSOR AND METHOD OF DETECTING FAULTS THEREWITH      This invention relates to sensors for detecting a fault condition, e.g. excessive temperature or leakage of fluid, in a large apparatus, and to methods of using such devices.      The novel sensors comprise a conductor, an element composed of a conductive polymer whose resistivity increases sharply when a fault condition occurs, and a dielectric element which separates the conductor and conductive polymer element so that they form an electrical capacitor. The sensor is in the form of a sheet or cable whose capacitance is periodically measured. When a fault condition occurs, the conductive polymer element increases sharply in resistance in the region of the fault and reduces the capacitance of the sensor, thus signalling the occurrence (and preferably also the location) of the fault. Figure 1 shows a typical sensor in the form of a cable comprising a central conductor 10, a dielectric layer 12, a PTC layer 14 and an outer protective layer 16.      The invention is particularly useful for detecting localised overheating, e.g. in dryers for agricultural products, or leakage of a fluid, e.g. for a conduit.

An electrode secured in fixed relation to a movable stylus is disposed between first and second electrodes to form first and second variable capacitors therewith.  The capacitance of the variable capacitors change in accordance with the motion of the stylus related electrode between the first and second electrodes.  A time varying signal is applied through fixed impedances to the first and second electrodes, the amplitude of the signal being modulated by voltage variable impedances connected between the first and second electrodes and a point of fixed potential.  The modulated signals at said first and second electrodes are coupled to the stylus related electrode and the time average of the summed signal is indicative of the position of the stylus related electrode and thereby the stylus with respect to the first and second electrodes.

Abstract: TITLE       OSCILLATING  CAM FEED  APPARATUS FOR A PRESS               ABSTRACT OF THE DISCLOSURE An input shaft of a press feed is rotated at a preselected speed and is drivingly connected to a cam that rotates with the input shaft.   Continuous rotation of the cam is converted to oscillating rotational movement of a cam follower through a preselected angle of notation.  The cam follower is nonrotatably connected to an output shaft that is connected by an adjustable linkage mechanism through a pair of meshing gears to a driven feed roll.  The oscillat-ing rotational movement of the output shaft is transmitted to the driven feed roll to advance the driven feed roll in contact with stock material through a preselected degree of rotation corresponding to a preselected feed length of the stock material to the press.  The feed length is adjustable by changing the length of travel of the linkage mechanism with respect to the degree of rotation of the output shaft. The driven feed roll rotates through a preselected angle in a first direction to feed a selected material, remains stationary during a first dwell period, is released from the material and rotates in the opposite direction back to the initial feed position, remains stationary for a second dwell period,  and engages the material  for another  feed cycle.          The intermittent feeding operation is coordinated with the operations of feed roll release and stock material clamping.

Abstract: ABSTRACT A screwdriver bit having longitudinally extending ribs on a shank portion is inserted into a longitudinally extending bore in the end of an elongated shaft.  The shaft about the bore is then swaged to a polygonal cross section, forcing metal from the shaft into the recesses between the ribs.  The polygonal cross section provides en-gagement surfaces that can engage a correspondingly shaped bore in a removable handle, while the flow of metal into the recesses causes a liquid-tight metal-to-metal contact that prevents liquid applied, for instance, in a subsequent etching step from seeping into the bore in the shaft.
