Title: Disengagement system for a "pull-type" friction clutch with detent means for automatic assembly/disassembly
Inventor: MAUCHER PAUL
IPC: B60K23/02
Filed: 1992-08-12
Abstract: A disengagement system for motor vehicles with a friction clutch of the "pull-type construction" comprises a guide part (6) slidable along an axial guide (7) provided on the output side, a rolling bearing (8) provided between the guide part and the clutch disengagement means (3) with a track (10). A connecting means (5) is provided for connecting the disengagement system (1) to the clutch disengagement means. Part (B) of the disengagement system (1) has a locking connection (C) with a detent means (11) which can drop into a recess (12) after compressing spring (13) and part (A) has an engagement contour (15) for positive engagement through the detent means in disengagement direction (I). Before assembly of engine and output the disengagement system (1) can be pre-assembled partially with part (A) of the locking connection on the engine and with part (B) of the locking connection on the output. During assembly (see figs 1a - 1c) the detent means (11) is forced into recess (12) by incline (16) after passing the incline the spring (13) forces the detent up so as to engage contour (15). On disassembly (see figs 1b - 1f) unlocking member (17) forces the detent down into the recess when guide part (6), which is fixed to member (17) by tongues (20), is moved axially in direction (I). The system may be actuated by a clutch fork (25) or alternatively by a piston cylinder, eg hydraulic. unit (fig 5) which may have a further pneumatic cylinder to aid disassembly. <IMAGE>

For increased speed shafts 2, 8 are locked together by clutch 17, the drive then being transmitted through shafts 2, 8 and pinions 9, 11, a one-way clutch 20 permitting overrunning between shaft 8 and pinion 7. For reverse drive clutches 17a, 17b, 18 are released and a third clutch 19a, 19b engaged so that shaft 10 is driven by motor 1 through a pulley-belt gear 12, 13, 14, clutch 18 being used as a cushioning brake during the end portion of the return movement. Preferably, clutches 17, 18 are of the electromagnetic, and clutch 19a of the oiloperated multi-disc type. For a machine with a continuously running chain the drive 12, 13, 14 and clutches 18, 19a are omitted, and pulley 11 is directly secured to shaft 10. A number of different operating speeds may be obtained by providing an intermediate variable-speed gear of the axially-movable pinion type between shafts 2 and 10, Fig. 2 (not shown).

Title: Abandonment of offshore oil wells
Inventor: DIXON DAVID
IPC: E21B33/035
Filed: 1994-12-12
Abstract: A method and apparatus for abandonment of an underwater well head which includes a strip of capped concentric casings (36) with at least one casing supported within another casing by a suspension arrangement, comprises explosively severing the casings a pre-defined distance below the mud-line (37).

Patent GB-2286237-A (GB)
Title: Finned tube heat exchanger for gas fired boilers.
Inventor: CLACK WILLIAM JOHN
IPC: F28F9/26
Filed: 1995-01-16
Abstract: A heat exchange assembly comprises, an array (20) of closely spaced parallel metal tubes (25, 26) held by a succession of common transverse fins spaced along the tubes (25, 26), to define and surround an axial burner location (27). The tubes are arranged to intercommunicate by means of opposed shaped metal blocks (22, 24), one at each end of the array (20). Communication ducts are formed within the blocks, between adjacent pairs of pipe ends so that jointly the tubes define a liquid flow path passing through all the tubes between an inlet (29) and outlet (30). When viewed in a plane normal to the tubes, the tubes may be of different sizes, the sizes being such that the inner faces (37) lie on a line of geometrical shape determined by the burner and the outer faces (39) lie on a line (40) of different geometrical shape. <IMAGE>
Patent GB-2298094-A (GB)
Title: Surge arrester magazine
Inventor: JONES WILLIAM HOWARD
IPC: H01T4/06
Filed: 1995-02-15
Abstract: The magazine has a plastics body 10 with compartments accommodating surge arrester components for protecting five pairs of telephone or data lines. The arrester components are retained mechanically, rather than by welding or soldering, to facilitate replacement. Three-electrode gas discharge tubes are held between contacts 12, which engage the end contacts (13, Fig.4) of the tubes, and spring clips 14 which engage the central earth contacts 17 of the tubes. An earth slider 16 slides on to the body 10 to engage the clips 14 during assembly of the magazine. Small changes in the clips 14 and in a plastics backplate (11, Figs.1,7) of the magazine allow two-electrode tubes to be used instead of three-electrode tubes and also allow tubes of different sizes from different manufacturers to be used. When three-electrode tubes are used, the clips 14 have crossarms which press on the end contacts (13) of the tubes via plastics insulating shims 15. If a gas tube overheats, the crossarms of its clip 14 press through the shim 15 into contact with the end contacts (13) of the tube, which is thereby short circuited. Each pair of lines may have additional protection provided by semiconductor transient protectors inserted into spaces 19 in the body 10 to connect with the contacts 12.

Patent GB-2290259-A (GB)
Title: Image fixing unit for use with electrophotographic printing apparatus
Inventor: FUKUDA MASAHIRO
IPC: G03G15/20
Filed: 1995-06-14
Abstract: When the surface temperature of a heating roller (2) in an electrophotographic printing apparatus exceeds a predetermined temperature, the bearings (20) that rotatably support the heating roller are arranged so as to soften or melt. As a consequence, a pressuring roller (11) causes the heating roller (2) to move towards a temperature detecting device (10) which causes shut-off of power to the heated rollers. Consequently, when a defect occurs, the warm-up time after the temperature detecting device (10) works, up until the power to the heater (5) (which is eg a halogen lamp) is shut off, can be reduced. As a result, the electrophotographic printing apparatus can be prevented from becoming defective, thereby improving its reliability. The bearings may be of plastics material that melts at 200 - 230 DEG . <IMAGE>
