Abstract: ABSTRACT        A machine for clipping strip material including a blade operated in a cyclic manner having a cutting stroke and a return stroke.  A toggle linkage includes a toggle bar which moves in a longthwise direction to reciprocate the blade by toggle linkages.  The toggle bar is coupled to an actuating piston rod of a pneumatic cylinder.  End caps of the cylinder are recessed to receive piston exten-sions during final stages of piston travel for cushioning purposes.  Seal means engage each piston extension during the later stage of piston travel to trap air between the advancing piston and the end cap to dissipate blade and linkage inertia.  Exhaust ports within each of said end caps a?e valve controlled to release cylinder pressure at a desired pressure prior to completion of piston travel.           A modified cylinder includes exhaust poppet valves each subject to a valve regulated, poppet closing pressure as in the first form of cylinder and additionally having a surface area thereon against which a secondary supplement-ary source of air may act to hold the poppet closed against extremely high piston actuating pressures.  The modified cylinder further includes end caps each having a port served by an end cap mounted valve to admit a piston impinging charge and a remaining port admitting a second-ary flow into the cylinder and controlled by an end cap mounted valve.

Abstract: INVENTOR:  WALTER GUGGENB?HL      INVENTION: METHOD AND CIRCUIT FOR PRODUCING MEASURING            PULSES IN A PARTICLE ANALYZER    ABSTRACT OF THE DISCLOSURE                  A method of, and circuit for, producing measuring pulses in a particle analyzer for the analysis of particles suspended in a liquid, especially blood cells, comprising a conductivity or measuring cell, whose impedance between two terminals of the conductivity cell changes upon passage of a particle through such conductivity cell.  A controllable current supply powers the conductivity cell with a current regulated to maintain a reference value corresponding to a control value.  A receiver functioning as a high-pass filter and having high input impedance serves for the essentially currentless removal of a potential between the terminals of the conductivity cell and for forming a receiver signal corresponding to such components of such potential whose frequency is above a threshold or cut-off frequency corresponding to the high-pass filter.  The control value is formed from the sum of a predetermined reference value and the received signal.  There is formed a measuring signal proportional to the difference of the control value and the reference value and whose timewise changes correspond to the measuring pulses.

Each prop member includes an upper end portion connected to a respective end of each truss so that a pair of prop members is associated with each truss member.  Each prop member includes an extensible portion and a shoe which is adapted to support the prop member for slidable movement on the mine floor.  Guide mechanisms connect the exten-sible portion and shoe of each prop member to prevent relative movement between the upper end of the prop member and the shoe. The truss members are stabilized by a stabilizer device, such as a stabilizer bar secured to and extending downwardly from the end of each truss member and connected to the extensible portion of each prop member.  The stabilizer bar is yieldable so that the bending forces applied to the prop member by the truss mem-ber are relieved by bending of the stabilizer bar.  The pair of prop members associated with each truss member are movable in a direction either toward or away from the mine face relative to the other pairs of prop members by telescoping devices that interconnect the tandemly positioned prop members adjacent the mine ribs. The telescoping devices are connected to adjacent prop members in a manner to relieve the bending stresses that telescoping devices are subjected to as the pairs of prop mem-bers are moved relative to an adjacent pair of prop members.

Some of the modular components are particularly useful in the manufacture of larger or truck type tires but can also be used in the automatic or semi-automatic production of smaller passenger size tires. One of the principal modular components is a carriage mounted device for transfer of components such as bands or belt and tread assemblies, or finished tires, which also functions as a bead setter and as a retractable two-position idle journal support for the non-driven end of the main shaft of the tire building drum or shaper. The shaft supports a wide variety of shapers or drums for single, first or second stage building. The device is mounted for movement to and from the shaper or drum and includes a support arm which moves in a circular are to assume and maintain various positions during various periods in the machine cycle. For certain types of shapers, the device provides support and means for automatic removal and replacement of the outboard bead seal flange. A bead setter is supported on the device and is adjustable omnidirectionally to obtain concentricity and squareness and is also adjustable axially for accurate bead placement symmetrically about the axis centerline of the shaper or drum and thus the tire being built. A bead gripper, actuated by fluid power, automatically rotates clear of the bead flippers or apex and clamps the tire bead securely and squarely to ensure accurate bead placement while transferring the tire bead to its selected location. A retractable positive intermediate stop is employed to position the carriage of the device to perform its various functions. A wide variety of arrangements of the components may be employed performing various tire building processes for different types and sizes of tires.

Abstract: IMPROVEMENTS IN OR RELATING TO PRINTERS                  ABSTRACT A mechanism for a matrix printer has a robust single turn closed loop transformer secondary winding 3 as the moving part for driving a print stylus 9 into and out of a print position.  Each secondary loop threads a trans-former core 1 on which is wound a multi-turn primary winding 2.  A stack of such secondary loops, arranged with print styli 9 in a closely spaced print row across the stack are supported in a static magnetic field pro-duced by a magnetic assembly 10.  Energization of a primary winding 2 induces a large current flow in its secondary loop 3 which reacts with the field to drive the associated print stylus 9 into the print position.          In one embodiment, the stack of secondary loops are all mounted on a single pivot 6 and each swings about the pivot as a whole upon energization of its associated primary winding 2.  In another embodiment each secon-dary loop of the stack is formed so as to be elastically deformable (Fig. 7) whereby a portion of the loop car-rying the stylus 9 is deflected into the print position upon energization of its associated primary winding.
