Title: Method and apparatus for stimulating plant growth
Inventor: KASPERBAUER MICHAEL J
IPC: A01G7/00
Filed: 1988-05-30
Granted: 1993-09-07
Abstract: ABSTRACT OF THE INVENTION The present invention discloses a method and means for selectively simulating predetermined developmental responses in plants by the positioning of a reflective surface generally between the soil surface and the leaves of the plants.  The reflective surface is of a predetermined color for upwardly reflecting light of a predetermined wavelength for absorbtion by the plants, such that the upwardly reflected light of the predetermined wavelength selectively stimulates the photoreceptor systems of the plants for stimulating predetermined developmental responses.  A plastic mulch having an upper surface of the predetermined color is disclosed for selectively reflecting the predetermined waveband of light upwardly to the leaves of the plants.

Granted: 1992-02-04
Abstract: PACKAGE WRAPPING AND WEIGHING SYSTEM                 Abstract of the Disclosure Packages to be wrapped, weighed and labeled are fed into an infeed station of a wrapping and weigh-ing machine from an operator's position.  The packages are automatically wrapped and returned to a weighing scale positioned above the infeed station at the operator's position where the packages are weighed and a label is printed adjacent the weighing scale and within convenient reach of the operator.  The label is then manually applied by the operator as the wrapped and weighed package is removed from the scale,  Since the scale is within convenient reach of the operator, packages which are too large to be wrapped by the machine, or which need to be repriced due to mark-down or the like, can be manually weighed and labeled or relabeled from the operator's position.

Abstract: MACHINE FOR LABELLING BOTTLES OR THE LIKE             ABSTRACT OF THE DISCLOSURE    This invention relates to a labelling machine for bottles which includes a bottle feeding mechanism to feed the bottles to a revolving bottle support platform.  The support platform directs bottles to a labelling mechanism and an application mechanism prior to their removal by a bottle withdrawing mechanism.  The bottles are maintained against undesired rotation on the support platform by axial force on the top of each bottle to produce contact between the bottom of each bottle disposed on a support plate for each bottle turntable on the revolving bottle support platform.  The support plate includes a base portion and upper surface element having an upper contour in a central region thereof.  The upper contour matches the bottom of the bottle for receipt of the bottom therein.  The upper surface element is removably mounted on the base portion of the support plate and includes features for centering the upper surface element and the upper contour thereof on the base portion of the support plate.

Inventor: BECK MARTIN H
IPC: E04B1/66
Filed: 1989-05-12
Granted: 1995-06-13
Abstract: The present invention relates to an apparatus and method and uses a thin, yet strong plastic film as the intermediate layer for the waterproofing material and the film has a plurality of perforations therein. The film is highly resistant to crack propagation, and acts as a barrier to crack propagation between adjacent asphalt layers, thus providing superior protection from the elements.  The asphalt layers are interconnected with each other through the perforations in the polyester support layer.  Because of the strength of the polyester film, only a very thin layer of polyester is necessary and this results in a substantial cost savings. As an alternative to coating, it is possible to extrude or laminate the asphalt onto the PET film. Also a layer of asphalt may be applied only to one side of said film and extruded through the perforations with heads on the columns so formed to attach the asphalt to the film.

Abstract: ABSTRACT    Circuitry for performing high speed operations on certain Boolean raster operations in a workstation whose functions include the display of graphics images using multiple planes and having foreground and background colors.  The invented circuitry includes a logic circuit for determining whether a particular Boolean raster operation is one for which the high speed operation is available.  A Boolean raster operation is determined to be available for high speed operation if the outcome of the operation can be determined by reading only one operand, namely the source data.  If the other operand, namely the destination data, is needed to determine the outcome if the operation, then the operation is performed normally.  Otherwise, the operation may be performed by reading the source data only.

Abstract: 1,022,589. Window or door operating system. K. W. M. PETERSEN. Sept. 26, 1963 [Sept. 27, 1962], No. 37853/63. Heading E2M. [Also in Division G3] In a system for moving a member, e.g. a door or, as shown, a window 1, between two positions by means of an hydraulic or pneumatic cylinder 2 supplied with pressure medium, which may be compressed air, under the control of a thermostat 6, two valves 9 and 19 are included in the pressure medium circuit and can be opened by a mechanical action derived from the movement of the window so as to determine the two extreme positions of the latter. As shown, a rod 37 is suspended from the window and carries a weight 43. Two stops 39 and 40 may be fixed at any desired height on the rod 37, and are operative through levers 29 and 30 to open the valves. When the thermostat 6 delivers pressure medium from supply 7 through pipe 5 to open the window, both valves are closed. When the stop 39 impinges on lever 29, valve 9 opens and the pressure in pipes 28 and 5 is relieved to arrest movement of the window. The pressure in the cylinder 2 is just sufficient to hold the window in this extreme position. When the thermostat, through aperture 44, further relieves the pressure in pipe 5, the window closes until stop 40 impinges on lever 30 to open valve 19, whereby pressure-medium is supplied via supply 7, valve 19 and pipes 28 and 5 to the cylinder 2 to arrest downward movement of the window and hold the latter in this extreme position. Eccentrics 31 and 32, to which the levers 29 and 30 are pivoted, may be rotated to provide a fine adjustment of the two extreme positions.

Abstract: In a bolt assembly for inertial operating automatic firearms using the kinetic recoil energy, of the type comprising a locking bolt head and a floating bolt element with a spring interposed between them, the locking bolt head is a rotatable head having a cylindrical portion (1) and a shank (2) narrowed with respect to the cylindrical portion.The cylindrical portion (1) has two radial crescent shaped diametrically opposite projections (6), (7) adapted to enagge each an associated groove (12), (13) provided in the barrel (9) and to disengage therefrom by passing through two associated recesses (10), (11) having a shape corresponding to that of the two crescent shaped projections (6), (7) of the head.The shank (2) of the locking bolt head is received in a cylindrical bore (21) of the floating bolt element (19) and engages by means of a pin (5) projecting therefrom a helical slot (20) of the floating bolt element (19).interposed between the shank (2) of the rotatable locking bolt head and the floating bolt element (19) is a spring (30).When the arm is locked the projections (6), (7) of the cylindrical portion (1) of the locking bolt head are in the associated grooves (12), (13) of the barrel (9).At firing, at the beginning the floating bolt element (19), because of its reaction to the recoil of the arm, advances and compresses the spring.Immediately after the spring (30) spreads out and causes the floating bolt element (19) to move back which unlocks the rotatable locking bolt head and causes the pin (5) to slide in the helical slot (20) thus disengaging the rotatable locking bolt head from the barrel (9) and causing the projections (6), (7) of the cylindrical portion (1) of the head to pass through the two recesses (10), (11) of the barrel (9).The arm is thus open and reloads itself automatically in a conventional manner.
