Title: Fastener driving tool
Inventor: KERRIGAN JAMES E
IPC: B25C1/06
Filed: 1984-03-16
Granted: 1987-04-14
Abstract: FASTENER DRIVING TOOL A fastener driving tool of the type utilizing a motor driven energy storing flywheel and a recpirocating fastener driving ram employs a flywheel having a metal peripheral surface that selectively engages a metal surface of the ram in order to drive the ram into engagement with a fastener to be driven into a workpiece. An elastic cord returns the ram to a retracted position when the ram is disengaged by the flywheel, and a pair of elastic bumpers are employed to limit the travel of the ram in the direction of the retracted position and the direction of the fastener engaging position. The ram, bumpers and cords form a subassembly that permits the ram, cord and bumpers to be removed from the fastener as a unit. The cord is made relatively long to reduce the amount of stretch per unit length applied to the cord thereby to increase the life of the cord. The motor and flywheel may be rotated in opposite directions to reduce precessional forces.

Abstract: COMBINATION WEIGHING MACHINE HAVING SHORT SEARCH     ABSTRACT OF THE DISCLOSURE           A combination weighing machine for forming a charge of product closely approximating a target amount includes a plurality of weigh scales, each of which receives a quantity of product and produces a signal proportional to the quantity of product received.   The quantities are combined according to a combination searching sequence in a search operation, and a combination of scales which closely approximates a tar-get amount is dumped to form the desired charge.  The dumped scales are reloaded, and the process is repeated in a cyclic manner.  The speed of the cyclic process is improved without significantly sacrificing accuracy by allocating less time than necessary for a complete search of all possible combina-tions in the search sequence.   A search is terminated when the time expires, whether the search sequence is completed or not.

Abstract: ABSTRACT OF THE DISCLOSURE          The slanted closing rim of a valve plate includes a cylindrical portion at the rear side, having a diameter D1 which corresponds to the width of the plate and slightly exceeds the diameter D3 of the passage throat. A groove in the casing guides the narrow sides of the valve plate and accomodates a seal strip.  The grooves partly closed at the front side by a guide strip which in the bottom zone of the passage throat is a semicircularly extending strip.  The inside diameter D4 of this cylindrical strip approximately corresponds to that of the valve plate and its axis a extends at a level which is higher by half the difference between diameters D1 and D3 than that of the axis b of the throat passage.  A slanted closing rim of the valve plate is provided with shear arcs on its frontal points on each of the side edges. The two shear arcs form a kind of a plowshare deflecting the medium from the seal.

Abstract: ABSTRACT OF THE DISCLOSURE          The interior of two metallic bellows (7, 8) is in fluid connection through capillary tubes (5, 6) with temperature sensors (3, 4).  The temperature sensors (3, 4) are located in places whose relative temper-ature difference should be determined.

Abstract: ABSTRACT     "Apparatus for Gas Analysis"     A breath alcohol testing instrument comprises a breathing tube (10) connected to an instrument (15) for detecting alcohol, including a sampling system comprising a spring-loaded piston (30) arranged to draw a gas sample into a sampling chamber (21) in contact with an electro-chemical fuel cell (20),  A pressure sensor (52 detects a predetermined breath flow rate and starts a timer (53) which after a predetermined interval actuates a solenoid (40) to release the sample.  If the suspect interrupts normal breath flow the system does not "abort".  The solenoid (40) is still actuated automatically either immediately when the pressure sensor (52) indicates a predetermined drop in pressure or after the pre-selected time interval.  Simultaneously a "test fail" signal is generated (55) and applied to a warning signal generator (56) which actuates a visible or audible warning sign to indicate a non-standard test result.

Abstract: ABSTRACT OF THE DISCLOSURE         The glass melter has an outlet portion formed as a heating device for controlling the outlet flow rate of molten glass from the melter.  Raw batch material that is used to form the molten glass is heated to a molten state at a first temperature range.  The molten glass, while flowing toward the outlet of the melter, is cooled to a second temperature range to increase the viscosity of the molten glass to a desired level.  The outlet member then heats the exiting molten glass a predetermined amount to decrease the glass viscosity in accordance with desired flow rate requirements.          Heating of the outlet member is accomplished by imposing a relatively low voltage and a relatively high amperage on the outlet member.  Accordingly, by using the outlet member as a heater a controlled flow rate of molten glass from the melter is achieved.

Abstract: ABSTRACT   For a computer system having peripheral devices coupled to a common bus through interface devices transmitting and receiving messages containing an ad-dress code matching a stored address code, a dynamic address assignment system stores a unique address code in each interface device following system startup. On system startup each interface device stores a type number and an adjustable serial number, type numbers for peripheral devices of the same type being identical while serial numbers for all peripheral devices of the same type are adjusted to different values. A master controller transmits to all peripheral devices a series of universally addressed count commands. each inter-face device counts the count commands and, when the count reaches a poll number determined by the unique combination of stored type and serial numbers, requests and obtains a unique address code from the host compu-ter. The interface device thereafter stores and uses the unique address code in transmitting and receiving messages on the bus.

Abstract: ABSTRACT OF THE DISCLOSURE         An anisotropic elastomeric conductor is fabricated by stacking a plurality of metal sheets and elastomeric sheets where the metal sheets have a plurality of parallel electrically conductive elements formed therein. By coating a curable elastomeric resin on the metal sheets, and then curing the resulting layered structure, a solid elastomeric block having a plurality of parallel electrically conductive elements running its length is obtained.  Individual elastomeric conductors suitable for interfacing between electronic components are obtained by slicing the block in a direction perpendicular to the conductors.  The conductor slices so obtained are particularly suitable for interfacing between electronic devices having planar arrays of electrical contact pads.
