Granted: 1997-08-26
Abstract: To provide close coupling between movable elements, such as segments (18) capable of varying the effective diameter of a folding blade cylinder (2) or a movable jaw (38) of a folding jaw cylinder, a first gear gear element (21, 47) is coupled via a positioning spindle (20, 43) to the respective movable element (18, 38); a second gear element (22) is coupled to the spindle (20, 43) and further  rotationally coupled to the cylinder shaft (11, 35). A positioning or adjustment gearing, for example a differential, or a planetary gearing is positioned in close vicinity to a side wall of the machine, facing the respective cylinder, the positioning gearing being operable to be controlled to change the relative angular relationship between input or received rotation and output or delivered rotation, and being coupled to the second gear element (22), to receive rotation therefrom and further to the first gear element to deliver rotation and additional adjustment movement thereto. The adjusting gearing, which superimposes adjusting or positioning movement, is controlled by a   positioning control element, such as a hand wheel (not shown), or a remote positioning control motor (30) coupled thereto by a gear, and controlled, for example, by a suitable electrical-electronic control unit, which can receive input data relating adjusting movement to, for example thickness of paper products being folded, number of paper products in a stack, and the like.

Title: Method and compositions for inhibition of disorders associated with oxidative damage
Inventor: CARNEY JOHN M
IPC: A61K31/44
Filed: 1990-10-17
Granted: 2000-05-02
Abstract: Compositions containing as the active ingredient a spin-trapping reagent, preferably .alpha.-phenyl butyl nitrone (PNB), or spin-trapping derivatives thereof, in a suitable pharmaceutical carrier for administration to a patient, are disclosed for treating or preventing symptoms associated with stroke or other ischemic damage, aging or other conditions associated with oxidative tissue damage. For the prevention or treatment of damage as a result of ischemia, the compositions are administered prior to or during ischemia in an effective dosage to prevent or reverse predisposition of the cells to damage resulting from depletion of ATP and damage from free radical generation following reperfusion. Examples of diseases which can be treated include stroke, meningitis, progessive neuronal loss due to Parkinson's disease, senile dementia, and drug abuse, disorders arising from exposure to high pressure oxygen or enriched oxygen environments, and bleeding into nervous tissue as a result of trauma. For treatment of aging, the compositions are preferably administered one to two times daily by oral administration for a period of two weeks. A significant reduction in oxidized proteins and memory recovery is observed as early as seven days after initiation of treatment.

Title: Velocity measurement system
Inventor: PETROFF ALAN M
IPC: G01S15/58
Filed: 1992-07-24
Granted: 1996-07-09
Abstract: A sonic-type fluid flow measuring system wherein reflections or echoes of a burst (103) of ultrasonic en-ergy from an ultrasonic acoustic emitter (9a) are sensed and typically comprise a number of frequencies represen-tative of a number of discrete velocities of flow in a volume of fluid.  A receiver transducer (13a) is gated to receive echoes from a selected volume of fluid (104) a selected distance from a transducer (13a).  Thereafter, this time domain signal sample is converted to a frequen-cy domain sample whereby the presence and magnitude of each frequency component, or velocity component, is iso-lated, this being typically done by what is known as a Fast Fourier Transform unit, obtaining a frequency domain waveform representative of average flow velocity.

IPC: A01N63/60
Filed: 1991-09-10
Granted: 2000-07-25
Abstract: In a method of conferring nematode resistance to a plant, identification is made of a gene which is induced within a nematode infected plant as a result of the infection. The so identified gene is then modified to confer nematode resistance to the plant. The method avoids this use of nematicides, which can be toxic, and improves on cultural and existing gene techniques by being universal in application and persistent.

Title: Sod roll-out machine with endless tracks
Inventor: WOERNER EDWARD E
IPC: A01B45/00
Filed: 1994-03-11
Granted: 2002-05-21
Abstract: A sod roll-out machine with endless tracks having a low center of gravity to prevent tipping on hills or inclines. The machine can be operated and steered by one person, wherein the roll of sod can be unwound in a forward or reverse direction. A pair of arms are elevated by hydraulic cylinders to facilitate the loading of a roll of sod to the distal ends of the arms, and to maintain the roll of sod slightly above the earth during the unrolling process. Due to the unique two track driving mechanism, the machine can be turned in place and operated in areas having limited accessibility. The tracks are driven by a motor, wherein each track can be individually controlled to be rotated in either a forward or reverse direction. A hydraulic pump is driven by the motor, wherein hydraulic fluid is provided to each of the hydraulic cylinders to control the elevation of each of the elevating arms. A cradle member is defined at the distal end of each arm for receiving a rod which is projecting out each end along an axis of a roll of sod. Hence, the loading and unrolling process is easy to perform. Large rolls of sod can be transported and unrolled thus minimizing the number of rolls of sod required to create a lawn. Further, the manual labor required by the operator is reduced as well.

Abstract: A fastening system for joining two timbers while keeping the mechanical linkage concealed. The linkage comprises a tubular connector extending into each timber perpendicularly to their contact area and two expandable cross-pins securing theconnector to both timbers. Each expandable pin is constructed as a cylinder diametrically divided along its axis and having internal recesses at each end to accommodate opposing wedges linked by a screw. Actuation of the screw serves to force the said wedges towards each other and thus pry both halves of the cylinder apart, thereby increasing the diameter of the pin perpendicularly to the dividing diameter. Near each end of the tubular connector there is an elongated transverse perforation of such dimensions as to allow insertion of an expandable cross-pin through the said connector and to allow the expansion of the said pin in the direction of the connector's axis. Each cross-pin extends substantially from both sides of the connector into a suitable bore in one timber, and prevents the withdrawal of

Title: Apparatus and a process for recording photometric data that is positioned in succession or in adjacent fashion on a page-like or strip-like print
Inventor: BERNER MARKUS
IPC: G01N21/55
Filed: 1994-05-11
Granted: 2005-08-16
Abstract: An apparatus for recording photometric data that is positioned in succession or in adjacent fashion on a page-like or strip-like print is equipped with at least one reflectance measuring unit with a reflectance measuring lens for measuring opaque prints (for example, paper test strips for examining the paper developing baths or for control of the basic printer setting). Wavelength dispersion elements positioned in the light path of the reflected light permit the analysis of the measuring fields according to wavelengths and preferably in the three primary colors of red, green, and blue. The apparatus can be equipped with an automatic transport device for the page-like or strip-like prints; the transport device is positioned behind the measuring lens. The prints are inserted into the device through an intake slot which is designed to accommodate prints of different width. On at least one side of the intake slot there is at least one stop for the prints. Each stop is stationary relative to the intake slot for the prints. The reflectance measuring lens and the print seized by the transport device and transported in the longitudinal direction can be moved in the transverse direction, relative to one other. In this manner it is possible to measure adjacent measuring fields without having to reposition the print between individual measurements.
