Abstract: Abstract of the Disclosure A nailer for repeatively driving nails one at a time into material when a safety yoke movably carried on a nose of the nailer is forcibly pressed by an operator against the material to be nailed. When the safety yoke having an integral safety yoke lever moves upwardly against a com-pression spring, the safety yoke lever cams against a safety yoke pin in the body of the nailer and actuates a secondary trigger pivotally mounted in a trigger of the nailer.  When the operator pulls the trigger, the secondary trigger actuates a valve plunger in a trigger valve assembly releasing the air over a poppet assembly, and compressed air passes through a chamber in an upper handle of the body of the nailer causing downward movement of a pneumatic piston assembly carrying a driver blade to thereby drive a nail held in a channel guide of the nose into the material.  Air pressure builds up in a chamber in a lower handle of the body to bring the piston assembly to a rest position at the lowest point of travel.  The poppet valve-assembly cooperating with a valve seal and exhaust deflector exhausts the air above the piston assembly during the return of the piston assembly to a rest position.  A plurality of tabs on the nose mechani-cally engage and frictionally lock a nail magazine to the nose to supply a succession of nails to the nose during repeated nailing.  A scroll spring assembly affixes to the nose and biases a pusher in an adjacent track of the magazine towards the nose.  A stop in an outer end of the nail maga-zine prevents the pusher from being pulled out of the nail magazine and functions as a latch for the pusher during loading of nails through a slot disposed in the top of the nail magazine.  A safety yoke detent biased away from the nose by a compression spring is moved forwardly into a detent notch in the safety yoke by the pusher when the supply of nails remaining in the magazine reaches a predetermined number thereby preventing upward movement of the safety yoke on the nose and subsequent actuation of the secondary trigger by the safety yoke pin.

Abstract: ABSTRACT OF THE DISCLOSURE     An automatic steering mechanism for a sod harvester, in which a shoe follows the cut edge of a strip of sod.  The shoe has a working edge which slides along the cut sod edge and penetrates slightly into it, to resist the tendency of the shoe to ride up over the cut edge.  A ramp on the front of the shoe is also spaced away from the working edge for the same reason.  The shoe is mounted on an arm which in one embodiment actuates a pair of automobile points which transmit steering signals to a solenoid hydraulic steering valve.  A mechanical connection between the steered wheels and the arm provides feedback.  In another embodiment the arm on which the shoe is mounted is mechanically connected to and moves a valve shuttle bracket which operates the hydraulic steering valve.  Feedback is provided by a mechanical con-nection from the steered wheels to a mounting block on which the steering valve is mounted, to move the steering valve bodily in a direction which counteracts the movement of the shuttle.

Abstract: NORMALLY CLOSED PRESSURE COMPENSATED FLOW CONTROL VALVE     Abstract of the Disclosure A fluid flow control valve assembly for use in a hydraulic system of the type including a cylinder which raises and lowers a load responsive to the receipt and exhaustion of hydraulic fluid at a cylinder port provides metering of the hydraulic fluid from the cylinder port at a constant desired rate for lowering a load at a corresponding constant rate which has been raised by the cylinder.  The valve assembly comprises a valve block of solid material having a plurality of valve receiving bores and a plurality of fluid communicating channels.          A normally closed valve within a first one of the valve re-ceiving bores has an input oriface communicating with the cylinder port by a first one of the fluid communicating channels and an output oriface.  The normally closed valve is selectively actuable for permitting the flow of fluid from the cylinder.          A pressure compensating valve within a second one of the valve receiving bores has an input orifice communicating with the normally closed valve output orifice by a second one of the fluid communicating channels and an output orifice.  The pressure compensating valve within a second one of the valve receiving bores has an input orifice communicating with the normally closed valve output orifice by a second one of the fluid communicating channels and an output orifice.  The pressure compensating valve maintains a constant fluid flow pressure and a constant fluid flow rate from the cylinder.  A baffle within the second fluid communicating channel restricts the rate of fluid flow from the normally closed valve to the pressure compensating valve and thereby causes the pressure compensating valve to gradually increase the fluid flow rate from the cylinder to the desired fluid flow rate and to maintain the fluid flow rate constant thereafter.  The pressure compen-sating valve also includes means by which it is normally closed prior to the actuation of the normally closed valve and opens gradually in response to the fluid pressure developed by the hydraulic fluid exiting the cylinder.     -  1a -

Abstract: ABSTRACT         Packing containers of the non-returnable type are manufactured from weblike packing material which by folding and sealing is converted to parallelepipedic packing con-tainers. For reasons of geometry triangular corner lugs are formed in the process which are folded in and sealed to the bottom wall of the packing container. The folding takes place along the edges of the bottom wall which adjoin the corner lugs but, since the corner lugs consist of several layers of material, they are difficult to fold in a sharp and well-defined manner, which has a negative effect on the flatness of the bottom wall.         To facilitate the folding the corner lugs are delimited from the adjoining bottom wall by means of a crease line weakening the material which extends at an angle over the bottom wall of the packing  container. As a result the material will be folded on the one hand along the crease line, on the other hand along the actual straight bottom well edge which appreciably improves the flatness of the packing container bottom.

Granted: 1982-05-04
Abstract: Abstract of the Disclosure.            Fat in a fat-containing sample, in particular a milk sample,  is  determined  quantitatively by infrared absorption technique,  using as  sample waveband a band characteristic to carbon-hydrogen bonds, instead of  the  conventional  triglyceride  carbonyl  band. This avoids the dependency of the measured result on the fat composition of the sample.  Influences from other components in the sample are compensated for. A preferred method uses double wavelength determination, with sample wavelength in the interval from 3.475 to 3.51 µm and reference wavelength in the range between 3.51 and 3.60 µm.

Abstract: HYBRID HYDROSTATIC-PNEUMATIC    POWER GENERATION SYSTEM       Abstract of the Invention The apparatus of the present invention is comprised of transfer tanks which are located below the hydraulic head of a dam.  Connected to the transfer tanks are air inlets extending from the transfer tanks to the atmosphere, and having check valves located therein.  A water inlet and motor operated valve, interconnect the transfer tanks with the fluid behind the dam, and a water outlet and motor operated valve empty the transfer tank downstream of the dam.  Associated with the transfer tanks is a storage tank which is inter-connected to the transfer tanks by transfer lines having check valves at their transfer tank ends, and a turbine out-let extends from the storage tank to an air driven turbine.          In one embodiment of the invention two transfer tanks and one open-bottomed storage tank are located on the upstream side of the dam at its base.  Thus the pressure of the air in the storage tank remains essentially constant, and propor-tional to the head of water above the tank, regardless of the volume of air in it.  In this embodiment water outlets pass from the bottom of the transfer tanks through the face of the dam.  In a second embodiment of the invention two transfer tanks, which comprise elongate flow tubes, and sev-eral enclosed cylindrical storage tanks are located down-stream of the dam at its base.  This embodiment can be easily retrofit on existing dams, and if a pressure equalization line extends from the storage tanks to the reservoir behind the dam, this embodiment also provides for nearly constant pressure in the storage tanks.  The method which is employed with both embodiments of the invention comprises utilizing the hydraulic head of the dam to compress air in the trans-fer tank by admitting water through the water inlet means, and then storing the compressed air in the storage tank.          The transfer tank is then emptied of water, and thus filled with air, and the cycle is repeated.

Abstract: Abstract of the Disclosure A vacuum operated sewage system includes a static pressure sensor establishing a trigger signal at a selected first level in a standpipe.  The sensor is connected up-stream of a discharge control valve and actuates a trigger and timer controller at the selected sensed pressure to establish low for a predetermined period.  A suitable time delay capacitor in the controller prevents transient signal actuation.  A system pressure interlock senses the vacuum level of the system to disable the timer controller if system pressure is below a selected level.  The interlock may include a pressure level control valve connected to bleed the capacitor and disable the timer controller.  A system pressure sensing valve in parallel with the level control valve decouples the latter as long as the system level is above the selected minimum and thereby permits normal controller operation.

Abstract: ABSTRACT     A method of and apparatus for texturing a running ribbon of thermoplastic sheet material or film.  The ap-paratus causes a ribbon of such film to be forwarded from a supply such as a roll of thermoplastic material, thence about a circumferentially extending portion of a rotating texturing cylinder, and then downstream where the textured film may be further processed or where it may be wound on a spool to form a roll thereof.  The texturing cylinder com-prises a tubular member having a coating of spheroidal particles adhered to the surface thereof.  While the film is in contact with the texturing cylinder, it is both heated and urged against the texturing cylinder, causing the film to assume the textured image of the texturing cylinder.  The apparatus may further control tension in the film both upstream and downstream of the texturing cylinder at pre-determined constant levels.  A method of making the tex-turing cylinder is also disclosed in which an epoxy film having spheroidal particles dispersed therein is electro-statically coated onto the radially outwardly facing surface of the texturing cylinder.

Abstract: ?016-A? METHOD AND APPARATUS FOR FORMING A CONTAINER FOR LIQUIDS of the Invention An apparatus and method is disclosed for forming a liquid-tight container having a rectangular cross-section formed from a one-piece, T-shaped blank of paperboard material. The carton preferably-includes an access flap and straw element on one side thereof which, when manually lifted, exposes an end of the straw element from which the contents of the carton may be consumed by a user. The apparatus is compact in nature, possessing relatively few transport mechanisms which advance the T-shaped carton blank through a plurality of work stations. A novel method and apparatus for serially applying the straw element and access panel to the carton blank; is disclosed, wherein the straw element and a length of polyethylene coated Mylar tape is automatically bonded to the carton blank upon a rotating heat sealing and alignment drum. A conveyor for collating a plural number of the carton blanks about a forming mandrel is also provided, and is positioned transversely to the remainder of the apparatus thereby significantly reducing the overall size of the apparatus. An ultrasonic welder bonds the side seams and end closure panels of the container upon a rotating crossbar mandrel which eliminates any misalignment during the sealing process. A substantially rigid conveyor transport carries a plurality of the carton blanks through pre-form, filler, and end closure work stations, and includes plural anvils for the ultrasonic welding process. An ejector mechanism is additionally provided which ejects the filled carton blanks from the rigid conveyor along a dual direction path, thereby eliminating the possibility of creasing or puncturing the filled and sealed container. The apparatus of the present invention additionally accommodates the production of differing size containers with only minor adjustments.
