Abstract: DIRECT COUPLED WAY SYSTEM FOR MOVABLE HEAD BAND SAW MACHINES                              ABSTRACT           A direct coupled way system for band saw machines wherein a cutting band is trained in tension over spaced upstream and downstream band wheels which are supported by a movable head for moving the cutting band with respect to a work piece held in position in the path of the cutting band by an arrangement of support members.  A shoe is slidably connected to the downstream support member, i.e. the support member which lies between the work piece and the downstream band wheel.  A leg having a first end and a second end is connected at its first end tot he downstream section of the movable head and at its second end engages the shoe, the resulting way system thereby directly couples the downstream section of the movable head and the downstream support member to obviate deflections in the movable head and other structural components which result in dimensional changes in the distance between the downstream section of the movable head and the downstream support member which are caused by fluctuations in the cutting force.  The leg is connected to the downstream sec-tion of the movable head and moves with the movable head in relation to the work piece.  The shoe, being slidably connected to the downstream support member and to the leg, is permitted to move in the direction of movable head motion as the cutting band is moved into or out of the work area.  The shoe and leg may be integrally molded or otherwise rigidly connected in band saw machines where the movable head is constrained to one degree of motion relative to the work piece.  The shoe and leg are slidably connected in band saw machines where the movable head is per-mitted more than on degree of motion relative to the work piece.

Abstract: L'invention concerne un procédé pour identifier des objets marqués par bandes ou fils magnétiques minces, en utilisant le procédé de détection du passage d'une bande magnétique dans une zone de détection comportant au moins un cadre avec une bobine d'excitation alimentée en courant alternatif pour créer un champ magnétique alternatif, et une bobine détectrice équilibrée de telle sorte qu'aucun signal n'apparaisse en l'absence de corps magnétique à proximité du cadre. Le passage, par contre, à travers ou à proximité du cadre d'un objet portant une bande magnétique, engendre, à chaque alternance du champ d'excitation, un déséquilibre dans la bobine détectrice et l'apparition d'un signal ensuite appliqué à un dispositif de détection et de mesure de phase par rapport au champ d'excitation.  Le procédé est caractérisé par le fait qu'on utilise un échantillonnage de bandes en alliages magnétiques à cycles d'hystérésis différents, une valeur de code prédéterminée étant attribuée à chaque type d'alliage.  En outre, le décodage est réalisé dans le dispositif de détection par mesure du décalage de phase du signal par rapport au champ d'excitation, ce décalage étant alors caractéristique du type d'alliage et de la valeur de code qui lui est attribuée.

Abstract: METHOD AND APPARATUS FOR AUTOMATICALLY ADJUSTING            THE RESOLUTION OF A RADIO ALTIMETER OVER ITS                      OPERATING ALTITUDE RANGE                      Abstract of the Disclosure Method and apparatus for automatically adjusting the resolution of a CWFM radio altimeter includes a counter for counting a signal pro-duced by the altimeter having a period relatable to the altitude desired to be measured.  A counter counts the number of pulses of a time reference signal occurring over a predetermined number of periods of the altitude related signal.  The number of periods of the altitude related signal over which the time-reference-signal pulses are counted is automatically determined by a circuit responsive to the fullness of the time-reference-signal pulse counter to produce a signal after the counter has reached a predetermined count.  The next occurring multiple of the altitude related signal is then determined, and the number of time-reference-signal pulses then counted is divided by the number of the multiple found.      In a particular embodiment, the counters are binary counters, and the multiples determined are powers of 2, whereby the division is achieved by shifting the data in shift registers a number of places corresponding to the number of multiples of 2N found.

Title: Double action revolver apparatus and method
Inventor: DICHTER WILHELM
IPC: F41A19/53
Filed: 1978-07-14
Granted: 1981-07-07
Abstract: ABSTRACT OF THE DISCLOSURE    A double action revolver has a frame on which is mounted a cylinder, a trigger and a hammer.  A hammer or main spring is interposed between the trigger and hammer such that pulling the trigger causes the spring to compress and bias the hammer toward its fired position.  The position of the hammer remains essentially unchanged during initial trigger pull by virtue of a toggle spring device interposed between the frame and the hammer.  When the hammer spring is sufficiently compressed, a surface on the trigger contacts and engenders a deflection or buckling of the toggle spring device.  Buckling of the toggle spring device permits the hammer spring to drive the hammer to the fired position in which a cartridge is fired.     A spring loaded cylinder stop, having a projection adapted to be received in a locking recess on the cylinder, is adapted to be displaced forwardly, against the bias of its spring load during initial trigger return from the pulled position to its normal or released position.  Each locking recess is constituted by a primary locking notch and secondary locking notch.  The primary and secondary notches are so arranged that forward movement of the cylinder stop causes it to leave the primary notch and enter the secondary notch   This permits the cylinder to be rotated a few degrees under the impetus of a cylinder spring.  Further trigger return permits the cylinder stop to move rearwardly out of the secondary notch and over the surface of the cylinder.  When the cylinder stop clears the secondary notch  the cylinder automatically rotates to the next index position where the cylinder stop enters the succeeding primary locking notch and terminates cylinder rotation.
