Abstract: A vehicle seat (10) includes a seat cushion assembly (12) for supporting an occupant seated thereon and a seat back cushion assembly (14) for supporting the back of an occupant seated on the seat cushion assembly (12). A first mounting assembly (18) is constructed and arranged to mount the seat cushion assembly (12) on a vehicle floor (20) and a second mounting assembly (13) is provided which is constructed and arranged to mount the seat back cushion assembly (14) on the seat cushion assembly (12). An adjusting mechanism (28) is operatively embodied in one of the first and second mounting assemblies (18, 13) and is constructed and arranged to enable the cushion assembly (12, 14) mounted by the one mounting assembly (18, 13) to be moved in opposite directions through a range of adjustable positions with respect to the assembly on which the one mounting assembly mounts the cushion assembly. The adjusting mechanism includes a locking and releasing device (42) constructed and arranged to be moved between (A) a locking position to lock the adjusting mechanism (28) to prevent movement in either direction of the cushion assembly (12, 14) enabled to be moved thereby, and (B) a releasing position to release the adjusting mechanism (28) to permit the cushion assembly (12, 14) enabled to be moved thereby to be manually moved in relatively unrestricted fashion in one direction and returned in relatively unrestricted fashion in the opposite direction. A vehicle crash sensing system (62) is operatively connected with the adjusting mechanism (28) and is constructed and arranged to provide control of the movement of the cushion assembly (12, 14) mounted by the one mounting assembly in response to the sensing of a crash condition which occurs while said locking device (42) is in the releasing position.

IPC: A61B17/17
Filed: 1999-06-17
Abstract: A device to releasably secure an object to a bone is disclosed. The device has a rotation restricting member which, while engaging the bone, prevents rotation of the member. The device also comprises an axial supporting member which axially secures the device to the bone, and preferably comprises a bone screw. While the bone screw and rotation restricting member engage the bone, a fastening mechanism fastens the rotation restricting member to the bone screw. In this way, objects can be releasably secured to the rotation restricting member or the bone screw by means of a clamp to temporarily axially and rotationally secure the objects to the bone. Preferably, the rotation restricting member comprises a sleeve and the fastening mechanism comprises a nut which engages threads on the bone screw. The sleeve comprises serrated teeth which, when biased towards the bone, engage the bone to restrict rotation of the sleeve. Rotation of the nut about the threads on the bone screw axially bias the sleeve towards the bone such that the serrated teeth engage the bone to restrict rotation of the sleeve about the screw and to fasten the sleeve to the bone screw.

Abstract: Means for detecting the flow of the steam at the gateway or the temperature of the outlet of the steam cooling system is provided. The timing of the finish of the warm-up process of the steam cooling system at start-up is decided by the difference of the flow of the steam at the gateway or the temperature of the outlet. In case of the difference between the flow of the steam at the inlet and the flow of the steam at the outlet, of the steam cooling system, or where the temperature of the outlet is below a permitted value, it is considered that residual air and drainage do not remain between the inlet and the outlet, the warming-up process is finished, and the gas turbine can be started.

Title: Device to control inflation characteristics of parachutes
Inventor: BUTLER MANLEY C JR
IPC: B64D17/62
Filed: 1998-04-21
Abstract: A round conventional parachute is shown with a small auxiliary canopy for controlling the inflation characteristics of the main canopy, especially large generally axisymmetrical canopies for heavy payloads. The main canopy has a central vent at the apex, and suspension lines descend from the lower edge or skirt of the canopy to risers or harness. The small auxiliary canopy is slidably attached to the suspension lines between the main canopy and the harness. The auxiliary canopy includes a generally hemispherical central inner section made of a low air permeable material and a generally annular flat outer section made of a high air permeable material, preferably one offering little or no resistance to air flow therethrough. The outer section is provided with spaced fittings around the periphery to slidably receive individual suspension lines therethrough. When packed, the auxiliary canopy is located near the mouth of the main canopy to control the shape of the mouth of the main canopy during opening but slides down the suspension lines as the main canopy fully inflates thereby controlling the opening sequence. By controlling the inflation characteristics of the parachute with the auxiliary canopy, the opening forces and/or the time to full open can be reduced, or increased, for a given speed.

Abstract: The sunscreen or makeup may be applied to a person who is wet, or even underwater, yet it will provide the full efficacy which it would have had had it been applied to the person when his skin was dry. In addition, it will be effective from the time that it is first applied, so no waiting period is required, as was the case for the so-called "water resistant" and "waterproof" sunscreens of the prior art. A series of test procedures which illustrate the efficacy of the "wet-appliable" sunscreens of the present invention are disclosed.

Title: Tamper resistant bait station for rats
Inventor: ISSITT NICHOLAS
IPC: E05B63/14
Filed: 1998-01-28
Abstract: A bait station for containing rat poison contains a housing (12, 13); at least one opening (15) in the housing for a rat to enter; and a bait position (16) in the housing for locating poisoned bait. A divider (18) is provided between the bait position (16) and each opening (15) to prevent direct access to the bait from the opening, for example by a child.  However, there are at least two different routes from the bait position (16) leading to openings (15). Research has shown that rats, unlike mice, prefer not to eat in a confined space and it is believed that the choice of escape routes offered by the bait station of the invention encourages a rat to eat more of the bait. The bait station may include a hinged lid (13) with locking means (24, 25) to prevent tampering with the bait.   I
