Patent GB-2097070-A (GB)
Title: Seal and seal assembly for an engine
IPC: F16J15/54
Filed: 1981-04-21
Abstract: A seal for an engine oil sump comprises an arcuate strip (5) of flexible sealing material each end of which terminates in a foot (7) extending radially away from the axis of curvature of the strip. Each foot defines one or more radial tongues having ribs (10) and being shaped to co-operate with a complementary recess in a gasket section which lies in the same plane as the foot, thus minimising leakage between the seal and the gasket section when assembled. The tongue(s) may be thicker than the gasket section. <IMAGE>

Title: Error correction of digital television signals
Inventor: COLLINS MARK CHRISTOPHER
IPC: H04N5/94
Filed: 1982-08-20
Abstract: A method of correcting errors in a digital television signal comprises forming the data words of the television signal into correction units each of which comprises a plurality of the data words and a parity word formed therefrom, and recording and subsequently reproducing on a digital video tape recorder (2) the correction units. On slow motion reproduction from the digital video tape recorder (2) a syndrome generator (30) derives a syndrome from the data words and the respective parity word of each reproduced correction unit. An error counter (30) counts the number of valid words in each reproduced correction unit. If this count is one less than the total number of words in the correction unit, the syndrome is used to correct the data word which is in error, and if the count is equal to the total number of words in the reproduced correction unit and the syndrome is not equal to zero, each of the data words in the reproduced correction unit is flagged as being in error.

Title: Child-resistant closure
Inventor: MUMFORD GEORGE VICTOR
IPC: B65D50/04
Filed: 1983-09-02
Abstract: A two-part child-resistant closure (11) comprises a cap (13), made of organic plastics material, having a top wall (14) and an internally threaded peripheral skirt (15), and a ring (22). A radial flange (17) on the skirt includes a plurality of circumferentially extending grooves (18) defined in part by lugs (19) and each receiving a respective lug (25) on the ring (22). When the closure is applied to a container, each lug (25) engages a substantially vertical surface (20) on a lug (19). Rotation of the ring in a direction to unthread the closure (11) from the container (10) without a downward force results in the lugs (25) on the ring (22) sliding up inclined surfaces (21) of the lugs (19). Thus a combined rotation and downward force on the ring (22) is necessary to remove the closure from a container. <IMAGE>

Title: Method and apparatus for severing by grinding
Inventor: MOSSEK JOHANN
IPC: B23D45/10
Filed: 1985-05-03
Abstract: Slab ingots, billets and the like are nowadays separated and cropped by means of a severing by grinding process. Known apparatus uses a single severing disc which must be of sufficient working diameter to cut through a workpiece. In order to make the severing operation more economical, and particularly to utilize the disc to better advantage, the present invention utilises two severing discs (26,27) which act in the same plane on mutually opposite sides of the workpiece (3), one of which discs (26) only partially cuts through the workpiece (3) from one side, the other (27) completing the cut immediately afterwards. The discs (26,27) may be mounted on sliding carriages (18,19) as shown on respective swinging arms. <IMAGE>
