Granted: 1991-01-29
Abstract: COMBINATION DOORSTOP, HOLDOPEN AND SHOCK ABSORBER            ABSTRACT OF THE INVENTION       The device includes a coiled extension spring, one end containing a hook for pivotal attachment either to the door or door frame,  the other end being open to receive an elongated,  tubular guide,  one end of which threads into the open end of the spring.  The other end of the guide is closed and contains a coaxial aperture through which slides an elongated rod having one end adapted for pivotal attachment to the other of the door or door frame and a piston attached to its second end which is slidably-retained within the guide to position the rod during relative coaxial sliding of the rod and guide,  and to stop the rod against further protractive movement when the piston abuts the closed end of the guide.   Camming surfaces located radially on the piston cooperate with opposing follower means in the guide, of which two embodiments are disclosed, to clamp the piston in the most extensive position of the rod, which clamping action can be overcome by a retractive force of the rod of a predetermined amount.  When in the fully-protracted position,  the  device  is  capable  of  absorbing  large amounts of shock, such as would be caused by collisions by heavy objects against the door.

Granted: 1992-07-14
Abstract: ABSTRACT         Internal combustion engine, more specifically a free-piston engine, having at least one cylinder and a piston arranged therein and guided to be movable and sealed.  The piston performs axial stroke movements within cylinder chamber, and features cylindrical pro-jections extending axially spaced from the piston to either side and having at least over part of their length a diameter inferior to the diameter of the piston.  The projections are guided at least over some part of their length within axial cylinder bores and therein partially sealed.  Combustion chambers are pro-vided within the cylinder, which combustion chambers are formed and delimited by certain parts of the in-side cylinder wall defining cylinder chamber on the one hand and by certain surface parts of piston and its projections on the other hand.  The surfaces defining the combustion chambers being formed more particularly by end faces.  Inlet ports are arranged in the longitudinal wall to admit air or fuel/air mixtures, and outlet ports are arranged within the longitudinal cylinder wall so as to permit exhaust gases to be expelled.  The inlet ports and outlet ports are opening and cleared or covered and closed depending upon the axial position of piston and its projections.

Title: Method of manufacturing a pressure vessel with an improved sidewall structure
Inventor: YAVORSKY WILLIAM M
IPC: F17C1/06
Filed: 1987-07-13
Granted: 1992-03-24
Abstract: METHOD OF MANUFACTURING A PRESSURE VESSEL     WITH AN IMPROVED SIDEWALL STRUCTURE     ABSTRACT OF THE DISCLOSURE           A method is provided for constructing a thin-wall pressure vessel having a thermoplastic inner liner, a filament wound outer shell and at least one localized area of increased thickness in its sidewall.  The method includes providing an insert formed from thermoplastic material or other suitable material which is bondable with the material of the inner liner.  The manufacturer uses this insert to form a localized area of increased thickness in the sidewall of the pressure vessel.  First, the manufacturer blow molds or otherwise forms a thermoplastic inner liner and bonds the insert to the inner liner.  The manufacturer then provides a means for locating or finding the port of the insert and constructs the outer shell with glass filaments impregnated with a resinous material or other  suitable material.  Then, after locating the insert, the maker forms an opening which extends through the entire sidewall of the pressure vessel.

Abstract: "SUNBATHING FILTER WITH                     INCOMPLETE UV-B ABSORPTION"                          Abstract of the Disclosure Apparatus for use in sunbathing comprises a screen formed of a sheet of thermoplastic or fiber material which is transparent to the safe W-A wavelengths of solar radiation and the visible light range between 400-450 nm but which contains uniformly distributed therethrough a first agent which absorbs at least 80% of the UV-B radiation in the 310-320 nm range and all radiation below 310 nm, and a second agent and third agent which prevent transmission therethrough of some radiations above 450 nm wavelength, i.e. visible light and infra-red. The second agent may be an absorbing dye or pigment. The third agent may be finely divided carbon or ground glass. The screen may be mounted on a frame or fabricated into clothing so as to shield thesunbather from the acutely and chronically handful wavelengths of radiation, to prevent unpleasant overheating, and to provide subdued lighting. The relatively small amount of W-B transmitted through the material stimulates the production of new melanin in a sunbather, and this melanin will be later available for tranning by UV-A radiation.

Title: Gas discharge over-voltage arrestor having a line of ignition
Inventor: BOBERT PETER
IPC: H01T1/20
Filed: 1987-12-11
Granted: 1993-01-19
Abstract: ABSTRACT OF THE DISCLOSURE        A gas discharge over-voltage arrestor having a narrow tolerance range of response voltages due to the quality of a line or lines of ignition.  A gas discharge over-voltage arrestor has one or more lines of ignition without additives and impurities and has a relatively narrow resistance tolerance given a defined nominal value of resistance whose tolerance range amounts to 1/2 a power of 10 in a logarithmic scale.  Every line of ignition is produced by a non-contacting sputtering of carbon particles and is connected to the electrodes over its full width.  A reduction in the variation of the response voltage is thereby achieved.          The invention is particularly suitable for gas discharge over-voltage arrestors in a glass housing.

Abstract: SEASONAL RESET FOR ELECTRIC WATTHOUR METER REGISTERS      ABSTRACT OF THE DISCLOSURE      An electric watthour meter includes apparatus for delaying a seasonal rate change until data accumulated in the meter is read out.  Dates in a rate-change library, consisting of dates on which a rate change is authorized, are compared each day with the current date.  When a match between a rate-change date and the current date is found, an arming signal is generated.  The arming signal remains ineffective until a reset signal is generated at the completion of meter reading.  Following the reset signal, the arming signal is reset.

QN values, ad-justed as appropriate, are subjected to entropy coding com-pression and decompression.  In the decompression process, pixel values are reconstructed. According to the invention, the reconstructed values are subjected to a vertical filter in which a pixel having a reconstructed value I0 is filtered to have a value I'0=I0+[(I-1-I0)C-+(I+1-I0)C+]   wherein C+ and C- are respective predefined clamping values, and wherein I-1 and I+1 are the respective reconstructed values of pixels adjacently below and adjacently above the current pixel.

Abstract: TILT-TUB BALE PROCESSOR HAVING TUB-MOUNTED ROTOR FEED CONTROL GRID            Abstract of the Invention Grid members for supporting a bale of hay within the tub of a tilt-tub bale processor are fixed to the floor of the tiltable tub and extend across an opening in the floor in order to control the feed rate of crop materials toward the chopping and disintegrating rotor. The tub is shiftable to any one of a number of slightly tilted orientations so that bottom reaches of the bale within the tub engage only a selected portion of rotor hammers.  If the rotor tends to plug, the tub can be tilted away from the rotor and the grid members supporting the bale simultaneously shift lower reaches of the bale away from the rotor hammers so that the latter are able to clear.   In preferred embodiments, a knife extends  across  the  floor  opening  in  transverse relation to the supporting grid members to provide a pinch point for crop materials entering the rotor chamber.

Granted: 1992-08-25
Abstract: ABSTRACT     In packing machines which have a filling pipe with two or more ducts a rinsing of the filling pipe with cleaning fluid may lead to  only one duct being properly cleaned.  In order to prevent this, an arrangement is provided on packing machines which has a coupling  part        provided  with  valves  with  passages which  are coupled  in series  with  respective ducts        in the filling pipe    .  The valve      is adapted so that it is acted on towards   the closed position by the cleaning fluid flowing past and  thus  limits the  flow through  the one duct      so that the other duct      too is assured of an adequate flow for effective cleaning.
