Title: Camera support column
Inventor: MCANULTY IAN
IPC: F16M11/28
Filed: 1990-12-20
Abstract: A camera support column comprises three tubular column sections (2, 3, 4) telescopically mounted on a base (1). The outermost upper column section (2) is supported on the base (1) by a set of three circumferentially spaced bearings (14) which are mounted on, and extend through the wall of the base (1). The intermediate column section (3) is supported by a similar set of three bearings (13) mounted on, and extending through the outer column section (2). Similarly, the inner column section (4) is supported on a set of three bearings (12) mounted on, and extending through the intermediate column section (3). The bearings of each set of bearings (12, 13, 14) are offset relative to the bearings of the other two sets. A pulley and cable arrangement (6, 7, 8, 9, 10, 11) is provided for elevating the outermost column section (2) relative to the base (1) and for interconnecting the three column sections (2, 3, 4) such that elevation of the outermost column section (2) causes the sections to expand telescopically. With this arrangement a very compact structure can be obtained as a spacing between adjacent column sections can be less than the radial depth of each bearing section. The number of column sections in the support columns can therefore be increased from the conventional two sections to three or more sections.

Title: Glass coated with mixed oxide of aluminium and vanadium prior to coating with tin oxide
Inventor: TERNEU ROBERT
IPC: C03C17/34
Filed: 1991-08-29
Abstract: Pyrolytic tin oxide coatings formed on soda-lime glass, particularly those formed from a tin chloride precursor, suffer from haze at the glass/coating interface due to the migration of sodium ions from the glass into the coating. Tin oxide coatings also exhibit iridescence in certain thicknesses. In order to reduce iridescence and to provide a barrier against the incorporation of sodium into the tin oxide layer, the glass is first provided with an undercoating layer of oxidised metal which contains aluminium with a minor proportion of vanadium. The optical thickness of the undercoat is selected for the reduction of reflected visible light interference effects due to the tin oxide overcoat. An intermediate product comprises a glass substrate bearing a pyrolytically formed oxidised metal coating which comprises a layer in which said metal comprises aluminium with a minor proportion of vanadium and which has a refractive index of at least 1.67. The undercoating is prepared using a precursor solution comprising aluminium acetyl acetonate and vanadium acetyl acetonate, which may contain glacial acetic acid as solvent. The substrate is preferably formed of float glass. The tin oxide coating may have a thickness of 250-700nm and may be prepared by pyrolysis of an aqueous solution of stannous chloride containing ammonium bifluoride for the provision of fluoride doping ions.
Patent GB-2259501-A (GB)
Title: Buckling fed sheets to de-skew
Inventor: FRANK NICHOLAS
IPC: G03G15/16
Filed: 1991-09-11
Abstract: A laser printer has a circulating photoreceptor belt in cassette 1 and a transfer station 4 at which toner images are transferred from the belt to copy sheets. Each copy sheet is registered, upstream of the transfer station 4, in the nip of registration rolls 12 before being fed to the transfer station. The copy sheet is fed to the registration rolls 12 (which at that time are stationary) by feed rolls 13, 14 which continue to rotate so that a buckle is formed in the sheet to assist in removing any skew. When the sheet has been registered, the registration rolls 12 are rotated and, initially, are accelerated to a speed about 20% greater than the normal operating speed. That has the effect of decreasing the amount of buckle in the sheet before the trail end of the sheet reaches the registration rolls. When the buckle has been reduced, the speed of the rolls is reduced to the normal operating level, which is typically about the same as the speed of the photoreceptor belt. <IMAGE>

Title: Letterbox television signal with chrominance helper signal
Inventor: CROLL MICHAEL GEORGE
IPC: H04N7/00
Filed: 1992-12-10
Abstract: In a letterbox-type video signal, in which a main signal is sent on the lines forming the central three-quarters of the picture, additional helper information is transmitted in the upper and lower borders of the picture. This helper information includes chrominance components that provide enhanced horizontal detail, for vertical frequency components up to a small proportion of the vertical detail carried in the main signal. At the encoder the chrominance components are vertically sub-sampled (16) to produce one line from every six input lines, and are horizontally stretched (18) and split (20) so that each input line extends onto two lines. At the decoder the operations are reversed by retiming onto one line and horizontal compression (42) and vertical super-sampling or interpolation (44). The extra chrominance detail can then be added (46) to the main signal chrominance components to enhance the horizontal detail.
