Abstract: A multi cone clutch is used on the input to a transmission. The clutch has a multi-cone structure which employs sandwiched cone friction surfaces. The multi-cone structure is used for gears selection inside the transmission. In this case, sandwiched cone friction surfaces are in free or unengaged state while the corresponding friction surfaces are engaged. The cone selector is used to engage free rotating female part of a multi-cone selector. A hydraulic actuator is received by internal gear case wall to prevent any radial or axial movement of the actuator itself. The crown of hydraulic spring outlet piston is formed so as to clip in a housing of a thrust bearing is to provide relative rotational movements between cone clutch male part and a piston in idling or power transmitting mode.

Abstract: A multi cone selector in a transmission employs sandwiched cone friction surfaces 19A, 20A and 21A and these are shown in free or unengaged state while the corresponding friction surfaces as numerals 19, 20 and 21 are shown as engaged. This comparative illustration shows the relative positions of the surfaces at different times since the “A” surfaces and the non “A” surfaces are the same circumferential surfaces. The cone selector is used to engage free rotating gear a female part 22 of a multi-cone selector. A hydraulic actuator 23 is received by internal gear case wall 24 formed so as to prevent any radial or axial movement of the actuator itself. A hydraulic coupling, in this case the hydraulic coupling is formed as hydraulic springs or bags illustrated at 26. The crown of hydraulic spring outlet piston is formed so as to clip in a housing of a thrust bearing 29.

Abstract: In a transmission of the constant mesh type a number of gear selectors are driven by using a hydraulic coupling between input and output pistons. The hydraulic coupling functions as a hydraulic spring and force multiplier. A hydraulic actuator (23) is received by internal gear case wall (24) formed so as to prevent any radial or axial movement of the actuator itself. A hydraulic coupling, in this case the hydraulic coupling is formed as hydraulic springs or bags illustrated at (26).

Abstract: A foldable ironing board installation comprises an ironing board member, hinged to a lower panel member and connected thereto by a gas spring strut. The ironing board member can occupy a generally horizontal working position and an upright stowed position where it is coplanar with the lower panel member. An iron retention housing is arranged behind the lower panel member and stowed position of the ironing board member, and includes a surface which is inclined away from the member and to provide a rest for an iron so that the latter will rest against a wall of the housing.

Abstract: A digital multi-standard TV composite video encoder is provided for converting digital RGB signals, such as those generated by high color resolution TV game machines, into analog composite video signals that can be accepted by TV systems of various standards including NTSC-M, NTSC 4.43/50, NTSC 4.43/60, PAL-B/G/I/D, PAL-M, and PAL-N. The present invention integrates encoder and TV game machine in a single chip of integrated circuit, which employs only one single crystal oscillator and three jump lines for selection of the six standards.

Abstract: In a gaming machine having a set of reels (8) with fruit symbols equi-spaced around their peripheral edges, two of the reels (8) may each be provided with a shield (10) which would normally conceal the respective symbols from the player's view through the machine window. After a play when the reels (8) have stopped rotating, the player can select to reveal the symbol concealed by either or both shields (10), by moving the respective shield (10) which is pivotally mounted on the respective reel. Identification markings on each shielded reel (8) are always visible to the player to reassure the player that when the reveal facility is used no further rotation of the respective reel (8) takes place. The revealed symbol is combined with the other visible symbols to determine whether or not there is a winning combination.

Abstract: A method of cutting out components from aluminum sheets utilizes a routing tool. The sheet is held firmly in position by vacuum on a vacuum table during the cutting operation with the aid of a film of for example plastics material adhered to the back of the sheet, the routing tool being arranged to cut through the sheet but only partially to penetrate the film.
