Title: A transmission unit with a casing that retains lubricant oil
Inventor: MOORE JOHN WESTWOOD
IPC: F02B67/06
Filed: 2007-12-13
Abstract: A transmission unit for use in ancillary devices of an engine comprises a casing 13, an input shaft 12 rotatable in the casing 13, an output pulley 11, an epicyclic arrangement of sun gear 40, planet gears 19, a planet carrier 20 and an annulus gear 14, a one-way clutch 20, a ring of flyweights 44 which rotate with rotation of the input shaft 12 and a flyweight-operated braking mechanism 21, 22 for braking the epicyclic arrangement of gears. For a first range of lower rotational speeds of the input shaft 12 the transmission unit 10 has a first mode of operation in which drive is transmitted from the input shaft 12 via the epicyclic gear arrangement to the output pulley 11. For a second range of higher rotational speeds of the input shaft the transmission unit 10 has a second mode of operation in which the one-way clutch 30 locks the output pulley 11 to rotate with the input shaft 12. The flyweight-operated brake mechanism 21, 22 switches the transmission unit 10 between the first and second modes of operation. The flyweights 44, brake mechanism 21, 22 and epicyclic gear arrangement are all encased within the casing 13. Lubricant oil thrown radially outwardly away from the input shaft 12 is retained by the casing 13. The ancillary device may be a supercharger or a turbocharger or a pump etc.

Title: Enhanced resolution phase control
Inventor: KATAYAMA FUMIMASA
IPC: G05F1/455
Filed: 2008-04-04
Abstract: In a phase control method, an output power command value is selected from a plurality of selectable command values of triggering angle for a switching unit 5, such as 0%, 1%, 2%, 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%. The output power command value is selected according to an input power command value received from a controller in a higher level equipment 1, (such as a programmable logic controller or a personal computer) and an accumulated value of an output error. If the input power command value is different from one of the selectable values, an output error is generated. The error accumulates and when it passes a threshold a different selectable value will be used. This allows an enhanced resolution phase control method without using an expensive circuit and is particularly suited to heater circuits.

Title: Thioacetalisation of poly (aryl ether ketones)
Inventor: CROSS PAUL MARK
IPC: C08G65/334
Filed: 2008-05-22
Abstract: A thioacetalisation process is employed to modify poly (aryl ether ketones) (PAEKs), such as poly (ether ketone) (PEK), poly (ether ether ketone) (PEEK), poly (ether ketone ketone) (PEKK), poly (ether ketone ether ketone ketone) (PEKEKK), poly (ether ether ketone ether ether ketone) (PEEKEEK), poly (ether diphenyl ketone) (PEDK), poly (ether diphenyl ether ketone), PEDEKK (ether diphenyl ether ketone ketone) (PEDEK), poly (ether ketone ether naphthalene) (PEKEN), into poly (aryl ether thioacetals) which, unlike PAEKs, are substantially soluble in common solvents. The thioacetalisation process comprises dissolving the PAEK in a mixture comprising a solvent such as diethylether, tetrahydrofuran (THF), dioxin, dichloromethane (DCM), trichloromethane (chloroform), dichloroethane, dichlorobenzene and an acid such as trifluoroacetic acid; and intermixing a Lewis acid such as boron trifluoride-diethyl etherate and a thiol compound, such as 1,2-ethanedithiol, 1,3-propanedithiol with the PAEK mixture to form a poly (aryl ether ketone) (PAEK) corresponding to the PAEK in solution. This modification allows selected analysis techniques to be more easily performed on PAEKs, such as gel permeation chromatography (GPC). The thioacetalization may be reversed through a deprotection reaction to recover the original PAEK without substantial degradation, allowing for nondestructive characterization of the PAEK. Also disclosed is a polymer matrix composite comprising fibres and the thioacetalised PAEK, Further disclosed is a poly (aryl ether acetal) polymer comprising a soluble acetal derivative of a poly (aryl ether ketone) (PAEK) and an alcohol, such as 1,2-ethanediol.

Filed: 1962-03-15
Abstract: 1,036,127. - Thermal switches. OTTER CONTROLS Ltd. March 15, 1963 [March 15, 1962], No. 10017/62. Heading H2B. A cut-out comprising a pre-stressed blade 1, which may be of bi-metal, having a central tongue 3 carrying a contact which is snapped out of engagement with a fixed contact (not shown), for example, when ambient temperature rises or current through the blade is excessive, is provided with a latch for retaining the contacts open until it is manually reset. In the form shown in Fig. 1 a spring arm 19 is biased to the position shown by broken lines but is normally retained in a crimped groove 15 in tongue 3. When tongue 3 snaps the contacts open, arm 19 is released from groove 15 and moves to its broken-line position wherein it prevents the contacts being reclosed (Fig. 3, not shown). The end of arm 19 engages in a slot 20 in the end of a reset plunger 13, depression of which moves arm 19 back into the groove 15 and allows the contacts to reclose. In the embodiment of Fig. 5 (not shown) the latch is formed by an arm 22 normally urged against a small flange 24 at the end of tongue 3. When the contacts (not shown) are opened by snapping of tongue 3, the arm 22 moves across the end of the tongue to prevent it restoring until the plunger 13 is pressed to return arm 22 to the solid line position.

Abstract: 545,109. Photographic shutters. KODAK, Ltd. Aug. 11, 1941, No. 10190. Convention date, Oct. 31, 1940. [Class 98 (i)] In a photographic shutter of the type in which a pivoted master member 10 driven by a spring 16 has an arm 28 pivoted tb it which engages a projection 26 on the blade - operating ring so as to rock it forwards and backwards to open and close the blades when the mastermember is released, the arm 28 includes a latch element which engages the projection during the opening movement and a curved portion forming a cam which engages it during the closing movement, the latter movement being thereby rendered more rapid. As shown, the arm 28 is of L-form, and is urged in an anti-clockwise direction by a leaf-spring 33 which engages a hooked end 32. The arm is formed with a latching notch 30 and a curved cam surface 34, the radius of curvature D of which is less than the distance to the pivot 29. Fig. 3 shows the parts in the fully-open position of the shutter, the arm 28 having been moved to the right by the anticlockwise rotation of the master-member 10 with the notch 30 in engagement with the projection 26 on blade ring. At this point the arm contacts with a stop 35, so that during the return movement of the arm it pivots about the stop and causes the cam 34 to wipe over the projection 26, producing a rapid return movement of the blade ring to close the blades. Specification 491,885 is referred to.
