Title: Lath grating for supporting mattresses
Inventor: HOERBURGER REINHARD
IPC: A47C23/02
Filed: 1991-12-04
Abstract: ABSTRACT OF THE DISCLOSURE    A lath grating for the support of mattresses or the like includes a frame and a plurality of laths arranged parallel to each other.  Vertical supporting shafts are arranged at both ends of the lath.  The supporting shafts are connected to the lath in an articulated manner and are received by vertical guide bore holes provided in a row at the upper sides of the frame legs which extend in longitudinal direction of the lath grating.  Longitudinally extending chambers are cut out in the frame legs.  A device for supporting the supporting shaft in a spring-like manner and including inflatable tube-like bellows is provided in the chambers.  The chambers are tubular and the inflatable bellows directly contact the wall of the tubular chambers along the entire surface thereof as a result of the pressure prevailing in the bellows.  The supporting shafts directly contact the bellows.  The bellows are connected via regulating members to at least one pressure tank.

Abstract: ABSTRACT           A manually operated railroad car handbrake release system in which the release of the handbrake (12,112) at either end of a car (10,11) automatically causes release of the brake (12) at the opposite end of the same car.  Affixed to each handbrake unit is a hydraulic cylinder (21,121) with interconnecting hydraulic lines (25,26).  Brake releasing actuation at one handbrake unit pressurizes the hydraulic system so that the cylinder (21,121) affixed to the brake unit at the opposite end of the car is also actuated to release the brake (12,112) at that end.   Return springs (22,122) disposed about the cylinders piston rods (19,119) automatically  return  the  release  handles  (16,116)  and pistons  (20,120)  at  both  ends  to  their  non-actuated positions.   The brake  release system does not  include provision for resetting the brakes, and each brake mechanism must be individually manually operated to set its associated brake.

IPC: F16B37/02
Filed: 1992-01-30
Abstract: A tee nut is integrally made of a metallic material, comprising a shaft portion and a flange portion, the latter having two pairs of pawls projecting in the direction in which the shaft portion extends, the pawls being disposed radially of the flange portion.  The peripheral edge of the flange portion is formed with projections at positions opposed to each other in a radial direction which is at right angels with the radial direction in which the two pairs of pawls are opposed to each other, the projections extending in the same direction as that in which the pawls extend.  The clearances in guide rails of C-shaped cross-section constituting a feed track are substantially decreased in size by the presence of the pointed projections producing a decreased frictional resistance, and the overlapping of the flange portions due to the rise of the flange portions in the guide rails is prevented, thus ensuring smooth movement of the tee nut along the feed track.

IPC: G01D21/00
Filed: 1992-07-10
Abstract: ABSTRACT    A product, in particular a shoe, apparel, a ball or a fishing lure, incorporating an impact sensing element made from polymeric piezoelectric material.  In response to  impact,  the  piezoelectric  material  generates  an electrical signal to a battery-powered light- or sound-emitting unit or to an information display device which is at least partially molded into or contained in the product, thus causing circuitry to energize the light- or sound-emitting device from the battery or to display information on the information display device.  In some embodiments  involving  light-emitting devices  such as LEDs, the light is conducted to an outside surface of the product directly through the LED or via one or more optical fibers.  A shoe can be provided with numerous light-emitting  devices,  one  or more  impact  sensing elements, a temperature sensor and appropriate circuitry to process the impact and temperature information.  This information is then used to light appropriate light-emitting devices such as to display a bar graph of temperature  or  force  of  impact,  to  light  or  flash individual  light-emitting  devices  or to  activate  an information   display   device.      In   addition,   a microprocessor can  be  included  in  the  circuitry  to provide preprogrammed  control  of  the  light  emitting devices or to evaluate the input from the impact sensing element and then light the appropriate light emitting device or devices or to control the information displayed on the information display de2vice.

Filed: 1992-10-21
Abstract: At least one boundary control roll (62) is disposed adjacent a moving web (18) of paper or like material being imprinted with ink.  The web (18) of paper has opposing planar surfaces (18a, 18b), and at least one such boundary control roll is positioned in transverse non-contacting proximity to a planar surface of said web and rotated counter to the direction of travel of the web.  If multiple rolls are used, the rolls (62a, 62b) on opposing sides of the web (18) should be coacting and counter-rotating.  The boundary layer (BR) formed about the peripheral surface of each roll (62) is adjustably positioned within the boundary layer (BW1) adhering to the moving web.  By colliding the respective boundary layers, a zone of interference is created and the boundary layer (BF) of the web is significantly reduced in thickness.  In this manner, the thickness of the hot solvent-laden boundary layer adhering to each side of the web is effectively reduced.

IPC: C12N15/10
Filed: 1991-08-23
Abstract: A method for amplifying nucleic acid sequences in a template comprising at least one nucleic acid or mixture of nucleic acids wherein each nucleic acid comprises at least one strand. The method comprises the steps of treating the template with at least one oligonucleotide primer having a nucleic acid sequence that is substantially complementary to at least one nucleic acid sequence on the template under conditions such that the primer will bind to a segment that is substantially complementary to the primer, producing primed strands of nucleic acid. The primed strands produce extension strands, wherein the extension strands comprise the primer in combination with a sequence of nucleic acids that is substantially complementary to the template in a 5' to 3' direction from the primer. The extension strands are further treated with the primer producing amplification strands which are treated with primer. The amplification strands are repeatedly treated with primer to produce large numbers of amplification strands whereby the nucleic acid sequences of the amplification strands are substantially similar to nucleic acid sequences in the original template.
