Gaming machines (10) comprising a first game (12) which may be of a generally conventional reel-based type and playable by a user upon activation, and a second game (14) playable upon activation following successful play of the first game (12), the second game (14) comprising a roulette-type component (16). In an alternative embodiment the first game (12) may comprise the roulette-type component (16).

An electrical machine, such as an electric motor, dynamo or alternator has a casing with cooling vents enabling cooling fluid to flow into and out of the casing when the rotor of the electrical machine rotates. The rotor may be formed from conductive elements connected together at their outer regions by interconnecting members, which have vanes arranged to direct cooling fluid over the outer regions. Each conductive element is a metal strip with legs bent in opposite directions relative to the p...

The present invention provides a rotary drum (22) cutting machine for cutting or shredding lamina material such as tobacco leaf, comprising a support frame (10), means for compressing and feeding material to be cut, as a plug, to a mouth (14) mounted on the support frame, a cutter carriage (20) movably mounted on a track (23) on the support frame, a cutter drum (22) mounted for rotation on said cutter carriage, and drive means (26,27,51,52,28) arranged to move the cutter carriage between an open...

For improving characteristic uprising at the right-hand side of head-flow rate characteristic of a turbo machine, as well as for suppressing increase of vibration and/or noises thereof, a plurality of first grooves 24 in direction of gradient in pressure of fluid are formed on an inner flow surface of a casing, for connecting an inlet side of blades of an impeller and an area on the inner flow surface of the casing where the impeller blades reside in, over an inner circumference of the casing. A...

Apparatus for forming an array of elongate slots in the bore of a valve sleeve (1) where the slots are cut in the bore by an arcuately movable cutting tool (5) mounted on the apparatus and the movement of the cutting tool (5) to form the length and depth of each slot is under the control of a desmodromic cam (12, 13) and a variable offset between the pivotal axis (8) of the cutting tool (95) and the pivotal axis (10) of the followers (15, 16) contacting the cam (12, 13).

A wookworking machine that can easily and exactly form digitizing data for a plurality of workpieces even during the working operation on the workpieces, thereby considerably increasing the working efficiency. The woodworking machine according to the invention for working of workplaces into specified three dimensional form is characterized in that the woodworking machine is combined with a copying digitizing device and a computer connected to an NC copying digitizing device. The computer loads t...

A coin-operated entertainment machine has three or four rotatable reels with selectable symbols around their peripheries. The machine is operated by a player, after actuation by insertion of one or more coins, to cause the reels to rotate and come to rest with a combination of symbols displayed on a win line. If the combination is of a predetermined winning nature, an award, such as a payout of coins, is made available to the player. The operating system of the machine assigns an index to each s...

A machine for machining blind-ended slots longitudinally disposed within the bore of a sleeve (1) held in a chuck (4) in a work holding spindle (5) indexable about a rotational axis, a reciprocable cutting tool (2) mounted on a cutting spindle (12) the axis of which is offset from and at right angles to the rotational axis of the work holding spindle (5) in which the cutting tool (2) executes a succession of progressively deeper cutting and subsequent return strokes so that a number of blind-end...

A printing machine wherein printing onto a substrate is effected by a first movement of a print head (1) downwardly into contact with the substrate and then by a second movement over the surface of the substrate while thermal printing elements within the print head (1) are selectively energized. The first movement is controlled by downward movement of a pair of rollers (6,7) operated by synchronized angular movement of a pair of eccentric shafts (8,9) one of which is freely mounted within each r...

A high speed rotating electromagnetic motor/generator includes a rotor having a core of magnetic material, a layer of permanent magnet, a retainer ring and side walls of non-magnetic material. A stator is provided by magnetic steel laminations and winding slots. A case includes a cylindrical inner casing, a cylindrical outer casing and end caps which carry the machine bearings. The permanent magnets within the rotating part may be made of neodymium-boron-iron and produce a high flux density pole...
