Abstract: A collapsible boat (100) has a frame (102) covered by a hull skin (142), the frame (102) having two gunwales (104) and a keel stringer (114) terminating at two stem elements (116, 118). The ends (106, 108) of the gunwales (104) can be secured to the corresponding stem element (116, 118) by end connectors (132, 140) that connect to the stem element (116, 118) and are held by skin tension. Alternatively, the hull skin (204) can secure the gunwale ends (206) to the corresponding stem element (212), the gunwales (208) residing in closed-ended gunwale sleeves (214) and the hull skin (204) being configured to secure the gunwale ends (206) together and prevent upwards motion of the stem element (212). The closed ends (216") can be openable to install the gunwales (208). To tension the hull skin (142) over the frame (102), the keel stringer (114) can have a central joint (150) to allow installation in a bent configuration. The keel stringer (114) is straightened during assembly to increase its effective length, causing the stem elements (116, 118) to forcibly engage the hull skin (142).

Title: Eddy current brake system with dual use conductor fin
Inventor: PRIBONIC EDWARD M
IPC: B60L7/28
Filed: 2001-07-11
Abstract: An eddy current brake system with dual use conductive fin (40, 60) includes a linear array of spaced apart permanent magnets (16, 18) and a non-magnetic electrically conductive fin. The magnets are mounted with respect to the fin for enabling passage past one another at a distance sufficient to cause eddy currents to be induced resulting in a braking force between the magnets and the fin. A mechanical brake (36, 70) is provided for frictionally engaging the fin and a surface treatment of the fin and enables the fin to sustain mechanical abuse of friction without effecting a change in the eddy current braking.

Title: Method and device for slaughtering fish, in particular white fish
Inventor: PEIN ROLAND
IPC: A22C25/14
Filed: 2002-02-14
Abstract: The invention relates to a device and a method for slaughtering fish, in particular white fish. The inventive device (10) is characterised in that the intermittently driven fish receiving drum (12) can be rotated about a horizontal axis (20), thus improving the operation of the device, as the fish can be introduced without a lifting stroke. The intermittent motion of the fish receiving drum (12) also allows the actual processing of the fish to be carried out whilst the drum is in its resting position, thus enabling in particular, an improved quality of cut to be obtained.

Title: Hose clamp
Inventor: MEIER ULRICH
IPC: F16L33/02
Filed: 2002-03-22
Abstract: For obtaining a hose clamp which has a continuously smooth inner surface free of gaps and which requires an as short as possible length of band material, the inner band end portion 11 is provided with a tongue 17 the length of which is approximately half the amount by which the hose clamp is narrowed during tightening. During the first half of the tightening movement, the tongue 17 is guided transversely to the band longitudinal direction by a projection 23 which engages a slot 24 provided in the outer band portion 12. The slot 24 at its end is continued by a window 20 which starts at a step, and the tongue 17, during the second half of the tightening movement, passes through the window which then takes over the guidance of the tongue 17.

Abstract: A movable barrier operator (11) receives movement sensing signals from a sensor (13) and calculates corresponding speed of movement of a movable barrier. Such speed measurements lead to development of a median speed value over a monitoring window. The median speed value is used in a subsequent monitoring window to facilitate determining when speed of movement for the movable barrier has slowed in a way that likely corresponds to the movable barrier having encountered an obstacle.

Filed: 2002-08-16
Abstract: The invention relates to a locking-tensioning mechanism for a miniaturised high-pressure generator, the construction of said mechanism being configured only for the volume of liquid that is to be delivered. The volume that is to be delivered by said high-pressure generator can be retroactively modified by adjusting the stop of the elastic part. The basic components of the locking-tensioning mechanism and the high-pressure generator remain unchanged. At least one additional component is provided as a spacer in the form of intermediate rings, stepped pulleys, adjusting screws or adjusting nuts. A  continuous helical-sliding gear or a helical-sliding gear that can be adjusted in steps can also be used to adjust a stop of the elastic part. The volume to be delivered can be modified either discontinuously or continuously during the assembly of the locking-tensioning mechanism, or prior to the use of the high-pressure generator, or during the use of said high-pressure generator. The locking-tensioning mechanism for a miniaturised high-pressure generator with a reproducibly adjustable volume, lying in the microlitre range, of liquid to be delivered can be used, for example, in a high-pressure atomiser for producing an aerosol that can be inhaled, or in a needle-free injector for injecting a volume of liquid into animal or vegetable tissue.

Title: Reverberation sound generating apparatus
Inventor: ITO TSUGIO
IPC: G10K15/12
Filed: 2004-03-25
Abstract: A reverberation apparatus is designed for generating a reverberation sound from an input sound with use of an impulse response based on an instruction. In the reverberation apparatus, a first storage section stores first impulse response data representative of a first impulse response. A second storage section stores second impulse response data representative of a second impulse response which is different from the first impulse response represented by the first impulse response data. A new data creating section operates based on the first impulse response data and the second impulse response data for creating new impulse response data representative of a new impulse response in accordance with the instruction. A reverberation sound generating section generates reverberation sound data representative of the reverberation sound by filtering input sound data representative of the input sound with use of the new impulse response data, such that the generated reverberation sound is featured by the new impulse response.

Abstract: The invention comprises a belt tensioner (100) having a pivot arm (10) biased toward a belt by a torsion spring (30). The tensioner (100) also comprises a one-way clutch (36) coupled with a friction clutch (42). The pivot arm (10) of the tensioner (100) is connected to a one-way clutch (36). The one-way clutch (36) is cooperatively connected to a friction clutch (42) having a predetermined friction torque caused by frictionally engaged radially extending surfaces. The pivot arm may move relatively freely toward a belt by operation of the one-way clutch (36). At the limit of arm movement the one-way clutch (36) engages, preventing travel away from the belt in an opposite direction. The arm (10) may only travel away from the belt when a belt tension torque exceeds the spring (30) force plus a friction torque of the friction clutch (42).
