Title: Removable scaffolding anchor and removal tool
Inventor: ANDREWS CLIVE JOHN
IPC: E04G5/04
Filed: 1990-07-03
Abstract: A removable ring bolt anchor (1) for securing scaffolding adjacent the wall of a building, comprises an expansible sleeve (7) insertable into a predrilled hole in the wall, an expansion cone (9) which can be drawn into the split or weakened end of the sleeve (7) by inserting and tightening the ring bolt (2) in the cone (9) thereby to set the anchor in the wall, the sleeve (7) having an internal screwthread (8) which is larger in diameter than the external screwthread (3) on the ring bolt shaft, so that the ring bolt shaft can slide freely through the sleeve (7). When no longer needed, the bolt anchor is removable by first removing the ring bolt (2) and then inserting a double screw-threaded removal tool into the sleeve to engage both the threaded expansion cone (9) and the thread (8) inside the sleeve, after first knocking out the expansion cone (9) to collapse the sleeve (7), leaving the hole in the wall to be filled in. <IMAGE>

Title: Housing for temperature measuring apparatus
Inventor: HORSLEY JOHN
IPC: G01J5/02
Filed: 1990-12-14
Abstract: A light guide 10 has a window 12 through which radiation passes to a detector (not shown). The light guide 10 is provided with a housing 18 which defines a duct 20 through which a flow of cooling fluid passes. The duct 20 is arranged so that a proportion of the fluid flow passes over the external surface 13 of the window 12 to prevent deposition of contaminants thereon. A circumferential shield 24 and 40 extends around the window 12 to control the flow of radiation therethrough. The circumferential shield has a curved radial recess 38 therein which imparts a rotational component of velocity to the flow of fluid passing over the surface 13 of the window 12 to promote cooling of the shield 24 and 40. The shield is further provided with an annular internal step 42 which prevents radiation reflected from the inner wall 41 of the sleeve 40 passing through the field 24 and 40. <IMAGE>

Title: Signal processing method
Inventor: FURUHASHI MAKOTO
IPC: G10H3/12
Filed: 1991-08-14
Abstract: A method for processing a digital signal produced by digitizing an analog signal such as a musical instrument sound signal. The looping domain is set so as to be a whole number multiple of the block which serves as the unit for bit compression, and the parameters of the looping start block are formed on the basis of data of the start and the end blocks.

Title: Vehicle headlight reflector
Inventor: NINO NAOHI
IPC: F21S8/10
Filed: 1991-12-19
Abstract: A vehicular headlight reflector for forming a low beam light-distribution pattern by effectively utilizing the entire reflecting surface, and providing a light-distribution control function so that a pattern image generated substantially by a lower half surface of the reflector is located below the horizontal line and as close to the horizontal line as possible. A filament is arranged between a focus F of a reference parabola and a reference point D offset from the focus F so that its central axis extends in parallel with an axis passing through the parabola vertex O and the reference point D. A virtual paraboloid is assumed for each arbitrary point P on the reference parabola, the virtual paraboloid having an optical axis that extends in parallel with a light ray vector of a reflected light ray obtained when a light ray assumed to have been emitted from the reference point D and reflected at the point P, passing through the point P, and having the point D as its focus. A reflecting surface is formed as a collection of intersecting lines obtained when the virtual paraboloid is cut by a plane including the light ray vector and being parallel with the vertical axis (z-axis). Projected images of the light source are located so as to move around a rotation center on the horizontal line with a movement of representative points on an intersecting line in the reflecting surface. <IMAGE>

Title: Angling hook retainer
Inventor: FORREST NIGEL JOHN
IPC: A01K91/053
Filed: 1992-01-31
Abstract: A bait hock retainer which releases on impact with the water after casting comprises a body member (4) having a stub (5) over which a rubber sleeve (6) may be fitted with the cast line (1) being trapped between sleeve (6) and stub (5) by frictional engagement. The cast line (1) extends through an aperture (10a) in the body member (4) and passes through a slot shaped aperture (7) which is provided in a hook shaped extension (8). A split shot bead (9) is positioned at the end of the body member (4) adjacent the elongate slot (7). The body member (4) carries a dome shaped end (10) which serves to shield the baited hook (3) from drag forces when projected through the air and also to provide a suitable force acting in the direction A when the member impacts the surface of the water. Following impact against the water surface the body member (4) moves in direction A and the split shot (9) rides along the surface of the projecting part (8) causing the baited hook (3) to be positively disengaged from the projection (8) and thus to be released. <IMAGE>
