Granted: 2007-10-30
Abstract: A spinal fixation device for stabilizing one or more segments of the human spine and for preventing the dislodgement of intervertebral spinal fusion implants (40, 41); which remains permanently fixated once applied. The staple member (12) is of sufficient length to span the disc space (D) between two adjacent vertebrae (V), to engage via essentially perpendicular extending projections (16, 17), the vertebrae (V) adjacent to that disc: space (D).- A portion (14) of the staple member (12) interdigitates with an already implanted intervertebral spinal fusion implant (40) which itself spans the disc space (D) to engage the adjacent vertebrae (V). The spinal fixation device (10, 11) is bound to the spinal fusion implant (40) by a locking means (60). The spinal fixation device (10, 11) is for restraining the vertebrae (V) adjacent to the spinal fusion implant (40, 41) from moving apart as the spine is extended and also serves as as anchor for multi-segmental spinal alignment means (600) for aligning more than one segment of the spine.

Title: Method for controlling the feed air temperature of a passenger aircraft
Inventor: SCHWAN TORSTEN
IPC: B64D13/08
Filed: 2004-12-30
Granted: 2009-08-25
Abstract: With a method for controlling the temperature of feed air supplied to a cabin area of a passenger aircraft (10), a measurement value for the ambient temperature in the cabin area is determined by means of a temperature sensor system (24). The temperature of the feed air is controlled, dependent upon a deviation of the ambient temperature measurement value in relation to an ambient temperature optimum value. In accordance with the invention, the ambient temperature measurement value is deduced from a number of individual temperature values for different points in the cabin area. In accordance with an example, the temperature sensor system used to establish individual temperature values for a cabin zone includes a number of discreet temperature sensors (24) positioned in this cabin zone, each of which provides an individual temperature value. Preferably, the temperature sensors (24) are distributed evenly over the whole length of the cabin zone in question.

Granted: 2010-06-29
Abstract: A dock leveler includes a pivotally extendable lip coupled to a pivotal deck by way of a front hinge, wherein the structure in the area of the front hinge optimizes the torsional flexibliity of the deck; provides a well supported, durable crown (apex angle beteen an extended lip and the deck); and reduces the part count of the dock leveler. The front hinge includes a deck-hinge member that extends approximately the full width of the deck and is preferably formed from a single sheet of material. A particularly narrow front header of flange disposed along the front edge of the deck reinforces the relatively thin deck plate so that the plate's rigidty more closely matches that of the thicker lip, yet the flange is sufficiently small to allow the deck to twist so that the deck can place the tip of the lip squarely upon a sideways inclined truck bed.

Title: Control system for bathers
Inventor: CLINE DAVID J
IPC: G05D23/19
Filed: 1999-08-31
Granted: 2011-01-11
Abstract: A control system for bathers includes an electronic controller which controls operation of an electric heater assembly connected in a water flow path for heating water. The heater assembly includes a heater housing and electric heater element. A solid state water temperature sensor apparatus provides electrical temperature signals to the controller indicative of water temperature at separated first and second locations on or within the heater housing. The presence of water in the heater housing is detected electronically, by turning on the heater, and monitoring the temperature sensors for unusual temperature rises or other faults for a period of time thereafter. A solid state water presence sensor apparatus can also be used to determine the presence of water within the heater housing, providing electrical water presence signals to the controller indicative of the presence or absence of a body of water within the heater housing. An independent circuit apparatus is connected to the water temperature sensor apparatus and to a power relay, automatically causing high voltage power to be disconnected from the heater assembly when the water temperature exceeds a predetermined temperature. The independent circuit apparatus requiring a manual reset once the water temperature has dropped below a predetermined level to allow the high voltage power to be reconnected to the heater assembly. The system includes ground continuity detection, ground current detection and ground fault detection circuits.

Title: Rotary mower over-center self-locking wing lift
Inventor: BOYKO STANLEY J
IPC: A01B73/04
Filed: 2007-04-10
Granted: 2011-07-19
Abstract: A wing-type rotary mower apparatus with a hydraulically powered over-center self-locking wing lift that extends between the central mower deck and the wing mower deck(s) to effect wing movement from a working position to a locked transport position. The lift mechanism comprises a double acting cylinder, a bell crank, and a pair of lift links that are pivotally connected. When the cylinder is retracted the bell crank rotates inward towards the center of the apparatus transferring the movement through the lift links to the mower wing(s). The rotational force on the bell crank about a fixed central pivot point on the central mower deck goes from an outward force reacted to by the cylinder to an inward force supported by the stop seat on the central mower deck; effectively locking the wing(s). The procedure is reversed when the cylinder is extended to return the wing(s) to the working position.

Abstract: An objective of the present invention is to provide methods of producing human collagen molecules that are easy to isolate and purify and that have a structure substantially equivalent to that of a natural collagen molecule, wherein host cells that are transduced with a collagen gene synthesize large amounts of human collagen protein derived from a gene introduced into a high exogenous gene expression vector. Another objective of the present invention is to provide collagen molecules produced by the production methods. The present inventors discovered that a large amount of human collagen hardly contaminated with host cell-derived collagen could be produced, by selecting from various mammalian cells a host cell that has low collagen expression and introducing a collagen gene construct into a vector capable of high exogenous gene expression.
