Patent GB-2297036-A (GB)
Title: Inflatable cervical dilator
Inventor: KOSTIC ALEXANDER
IPC: A61M29/00
Filed: 1996-01-05
Abstract: An inflatable cervical dilator comprises a flexible steel guide 4 on which is mounted inner balloon 3 covered by furled silk sleeve 5 which is in turn covered by outer balloon 2 . On inflation of inner balloon 3 , the furled silk sleeve 5 slides out of plastic body 8 to form a tubular shape suitable for cervical dilation. Protective outer balloon 2 follows the same shape and protects against leakage. Furled silk sleeve 5 once expanded cannot be retracted and restricts the device to once only use. A third shortened piece of balloon 10 holds the lower end of the silk sleeve 5 and is also used to pressure test the device during production. Evacuation holes 6 are provided in the plastic body 8 for emergency cessation of dilation.

Title: Folded active filter circuit
Inventor: BEATSON TREVOR PETER
IPC: H03H11/12
Filed: 1996-10-22
Abstract: A filter circuit comprises three stages 260, 270, 280, each having a differential input and a differential output. The output of stage 260 serves as the input of stage 270 and the output of stage 270 serves as the input of stage 280 respectively. Stage 260 comprises two transistor pairs 201, 202 and 203, 204. An input signal Vin is applied to the base electrodes of transistors 201, 204 which causes a current change in the corresponding transistor 202, 203 which have their respective base and collector electrodes connected together. The collector electrodes of transistors 202, 203 constitute the output of stage 260. Stages 270 and 280 have essentially the same structure as stage 260. The arrangement offers high frequency capabilities from a low supply voltage. In another embodiment (Figure 5, not shown), a cut-off frequency is varied under control of controllable current sources.

Title: Ventilating and air conditioning systems
Inventor: ROLANDO PAUL
IPC: F24F13/06
Filed: 1997-04-14
Abstract: A heating ventilating and air conditioning system comprises a diffuser (6) which serves when mounted adjacent the outlet of the system in a first orientation to diffuse air in a generally horizontal direction and, when mounted in an inverted orientation, to diffuse air in a substantially vertical direction. The diffuser takes the form of a disc-like element which is mounted within an opening defined in a mounting frame (3), co-operating means being provided for releasably retaining the diffuser in position within the opening. The diffuser is located within the opening with minimum clearance and the releasable retaining means serve to prevent undesired removal of the diffuser by hand without the use of a special tool. The system includes first (5) and second (12) components defining a plurality of similarly sized apertures (31 and 15) with the components being mounted adjacent each other and movable to provide differing degrees of alignment between the apertures in order to control a flow of air through the components. Means (33) are provided for releasably fixing the positions of the first and second components relative to each other to set a desired airflow rate, said means permitting the removal of one of the components and being such that the removed component can only be replaced in the same position, relative to the other component, as that from which it was removed thereby ensuring that the desired airflow rate is maintained. The system includes a plenum chamber (7) which is connected to a further component of the system by way of a substantially air-tight snap fitting connection (23 to 26).

Abstract: An entertainment machine 1 that selects a combination of symbols and displays them at a win zone 11, a win indication including an evaluation of a win award in relation to a stake made 20, is characterised by the provision of player controls 6a, 6b operable to select independently, from specified ranges a stake enhancement factor 18 and a game win mode 17. Symbols may be in the form of a 3x3 matrix 11 with up to five win lines, or a 4x3 matrix. The win mode may include lines or other arrangements in which symbol combinations are assessed for a win evaluation. All combinations of symbols, one taken from each column 9 in a 3x3 matrix may be chosen. The win mode 17 may be; determined by the presence of special symbols, related to losing game awards, or may not be related to displayed symbol combinations, including losing game awards. Preferably, the enhancement factor has a selection of numerical multipliers applied to all or selected wins. The controls 6a, 6b for the win mode 17 and enhancement factor 18 may be separate. Both controls 6a, 6b can be available; at the start of every game, after the game has started, or only in some games. One control may be partially available during a game. The win mode 17 and enhancement factor 18 may be displayed visually. The enhancement factor 18 can be applied to all or part of the available stake 20. Preferably, a pay out percentage 21 can be varied and displayed numerically. Preferably, a control system (12 figure 3) determines a variable win likelihood that is linked to the win mode and enhancement factor. The likelihood may be displayed numerically along side the win mode and stake enhancement factor.

Title: Pivotable beam mechanism for ink ribbon feeding
Inventor: MIDDLETON ALAN PETER
IPC: B41J33/14
Filed: 1997-08-16
Abstract: The pivotally driven beam mechanism 20 carries movable guide rollers 22,23 to feed ink ribbon from a supply reel 1 to a take-up reel 4 past a printhead 3 via guides 2,10-11'. Before printing, the beam pivots clockwise to form a loop A of unused ribbon, and a collapsed loop B of used ribbon. The beam then pivots anti-clockwise; printing follows, and loop B enlarges as the ribbon is used and loop A collapses. After printing, the printhead is moved to a rest position, and the beam pivots clockwise to repeat the pre-print operation.

Title: Chuck for a winding apparatus
Inventor: FORDHAM KEITH
IPC: B65H75/08
Filed: 1999-07-16
Abstract: In a web winding operation, a web is wound onto a core supported and driven by a chuck. The chuck is mounted on a drive shaft and torque can be transferred to an inner ring 30 of the chuck from the drive shaft. A casing 28 of the chuck surrounds the inner ring and supports core engaging elements 40. Each element may be a cam pivotably mounted on the housing and operated by a cam roller 58 mounted on the inner ring. Relative rotation of the inner ring and the casing causes the cam roller 58 to move along a cam surface on the underside of its cam and to raise either end of the cam to engage the core. The chuck has a switching element 80 which may comprise a spring 90 having a central detent and a detent roller 88 mounted on the inner ring. When the detent roller engages the detent, the detent roller is retained centrally within the chamber and each cam roller is corresponding held central beneath its cam. This prevents operation of the cam and engagement of the cam with the core. When the detent roller is moved to either side of the detent, the detent spring urges the detent roller towards a corresponding end of the chamber. This correspondingly urges each cam roller along its cam to raise an end of the cam into engagement with the core.

Title: Water flow proportioning valve; fountain feeder tube
Inventor: BROOKS STEVE MARTIN
IPC: F16K11/085
Filed: 1999-08-04
Abstract: A device for controlling the flow of water from a pump to two discrete destinations comprises a T-shaped body (1) with an inlet duct (3) and two outlet ducts (4,5). The supply of water from the inlet (3) to the outlets (4,5) is controlled by a rotatable valve member 2 mounted in chamber (6), the valve member having a cylindrical body section (2B) with a curved obturator skirt (12) extending therefrom. In order to distribute the water supply from the inlet duct (3) to the outlet ducts (4,5), the valve member 2 is rotated thereby partially covering one duct but at the same time uncovering the other. The water supply to the outlet ducts (4,5) is therefore varied proportionately and simultaneously on rotation of the valve member (2). A tube for supplying water to a fountain comprises a battle 24 which creates a back-flow and vane means 25 holding the baffle away from the wall so that the water may continue to the fountain head 21.
