Title: Reflector for vehicle headlight
Inventor: KAWASHIMA HIROSHI
IPC: F21V7/00
Filed: 1991-10-29
Abstract: An elliptical paraboloid, which is a basic surface, has an elliptical section when it is cut by a plane perpendicular to its optical axis, and has a parabolic section when it is cut by a plane including its optical axis. A light source 5 is arranged on the optical axis X. A cross sectional curve obtained when a reflecting surface is cut by a plane perpendicular to its optical axis is expressed by a finite-order vector algebraic expression by specifying its end point positions and coefficient vectors. As a result, the reflecting surface is formed as a free surface deviating from the basic surface. Operations for controlling the surface, which are important in forming a cutline, are an operation of making the tangential vector at the end point of the cross sectional curve orthogonal to the position vector, and an operation of twisting the surface. By these operations the light-distribution control is performed so that longitudinally extending peripheries of respective filament images can be flush with one another. Finally, a sharp outline is formed which is specific to a low beam. <IMAGE>

Title: Aligning golf ball mould halves
Inventor: MILLER SEWARD S
IPC: B29C45/14
Filed: 1991-11-06
Abstract: The exterior cover of a golf ball is formed between a pair of mating mould halves (10, 12). The mould halves have inclined alignment surfaces (40, 42) to bring the mould halves into precise engagement with one another on the parting line when the mould is closed along axis (14). One (12) of the mould halves is permitted limited lateral movement to ensure proper alignment along the axis of closure. The improved alignment prevents flash around the parting line, and also enables the golf ball to be configured with dimples on, or closely adjacent to the parting line. <IMAGE>

IPC: H04N9/78
Filed: 1994-04-28
Abstract: The YC separating filter comprises a first horizontal chrominance extraction filter (16) extracts frequency components corresponding to components of a color subcarrier in a horizontal direction to produce a first chrominance signal (107), a vertical chrominance extraction filter (15) extracts frequency components corresponding to components of a color subcarrier in a vertical direction to produce a second chrominance signal (108), a horizontal and vertical chrominance extraction filter (17) extracts frequency components corresponding to components of a color subcarrier in horizontal and vertical directions to produce a third chrominance signal (110). A first selector (23) selects one of the first, second and third chrominance signals, a second horizontal chrominance extraction filter (24) having a narrower bandwidth than the first horizontal chrominance extraction filter (16) is provided to receive the selected chrominance signal, and a second selector (25) selects the output of the second horizontal chrominance extraction filter (24) when the first selector selects either the first or third chrominance signal, and selects the output of the first selector (23) when the first selector selects the second chrominance signal. This reduces cross colour effects in areas of picture having diagonal stripes by reducing horizontal bandwidth of combing chroma signal. (see fig.8) <IMAGE>

Title: Cable holder
Inventor: BACH GERHARD
IPC: H05K7/02
Filed: 1995-02-27
Abstract: The invention relates to a cable harness support and a relay carrier for it. In order to hold the cable or the cable harness securely even against vibration, the intention being to occupy as little space as possible on the relay carrier, it is proposed to design a cable harness support as a cable harness bearing with an attached foot, the foot consisting of limbs which are in the form of plates and are arranged crossing over one another. At the end, that is to say on its installation surface, the foot is provided with latching projections. The associated relay carrier for accommodating the cable holder is designed such that webs are provided between the receptacles for relay bases, the width of which webs is greater than the width of the plate-shaped limbs which form the foot of the cable harness support. Recesses are incorporated in these webs, in which recesses the projections which are arranged on the foot of the cable harness support can latch. The recesses are furthermore arranged such that they correspond with the projections which are arranged on the foot when the centre axis of the cable harness support is above the intersection of the webs.

Title: A window stay with a composite closure member and ribbed links.
Inventor: LANAWAY RONALD PHILIP
IPC: E05D15/30
Filed: 1995-11-25
Abstract: A window friction stay has a link arrangement (16 - 26) pivotally mounted on a track (10), the latter and one of the links (16) being adapted to be secured respectively to a window frame and a window sash. In the closed position of the link arrangement, a nose (46) of the link (16) enters a closure member (32). The latter is a composite of a metal such as stainless steel and a moulded plastics, having a mounting part (34) in the track (10) and an upstanding part (41) where the metal provides an internal profiled, relatively hard wearing surface engageable by the nose (46). Each of the links may be formed from a strip of metal which has a thickness less than that conventionally required in a friction stay, material being displaced at selected locations across the strip in opposite directions, whereby the spacing between the outermost points effectively provides the required thickness of strip. The links so formed with ribs provide sufficient strength and other necessary qualities, while leading to a considerable saving in material costs.

Title: Mechanism for connecting an ink jet recording head to an ink tank cartridge
Inventor: UJITA TOSHIHIKO
IPC: B41J2/05
Filed: 1993-07-30
Abstract: A liquid storing container (303) includes a receiving case in which a porous member (310) having a large number of pores communicated with each other is received in the compressed state under an atmospheric pressure introduced via an atmospheric intake port (340) with a small diameter formed on said receiving case. The liquid storing container comprises a circular end filter (308) to which liquid is fed from an end part of the porous member when the filter comes in contact with the end part of the porous member. A shortest distance as measured from the periphery of a contact portion of the circular end filter (308) to the receiving case is smaller than the diameter of the contact range where the circular end filter comes in contact with the porous member.

Title: Reflex loudspeaker port has lining with a coarse texture
Inventor: NEVILL STUART MICHAEL
IPC: H04R1/28
Filed: 1996-10-21
Abstract: A reflex enclosure 1 for a loudspeaker drive unit 5 includes a port member 4. The interior surface 9 of the port member is, at least in part, of a coarse texture. A multiplicity of indentations 11 and/or peaks may provide the coarse texture. The indentations and/or peaks are advantageously misaligned with one another (fig. 11) and each indentation and/or peak preferably has a depth/height d less than its diameter w. The size and arrangement of the indentations preferably correspond to those on the exterior surface of a golf ball. The coarse texture may be provided by a layer of moulded plastics material on the internal surface of the port member. The provision of this coarse texture causes the pattern of movement of air 7 outside the enclosure 1 in the region of the tuning port 4 caused by the drive unit 5 to be diffuse, thereby reducing unwanted so-called "chuffing" noises.

Abstract: 965,278. Oxygen lances; delivering granular materials. ARBED, ACIERIES REUNIES DE BURBACH-EICH-DUDELANGE S.A. June 30, 1961 [Sept. 12, 1960], No. 23668/61. Heading F4B. Part of the oxygen or other gas passing through a metal refining lance is directed through holes 6 into an annular space 5 surrounding the convergent-divergent nozzle 2 to emerge through secondary nozzles 7 which are directed obliquely into the main jet. The jets from the nozzles 7 may converge to a point within the main jet, or they may give the main jet a rotary motion, while causing it to diverge to prevent splashing. The diversion holes 6 and secondary nozzles 7 may be convergentdivergent or may be cylindrical, and are arranged so that at least 20% of the gas flows through them. The lance is water jacketed and may be used to blow suspensions of granular material into a metal melt. Reference has been directed by the Comptroller to Specification 888,634.
