Abstract: A window fastener including: a base configured for connection to a window sash; a handle carrying a latching tongue, pivotally connected to the base between a latched position and an unlatched position; and an interface between the base and the handle, wherein the interface causes the latching tongue to move axially closer to the base when the handle pivots from the unlatched position to the latched position; and wherein the interface causes the latching tongue to move axially away from the base when the handle pivots from the latched position to the unlatched position.

Abstract: A window stay including a frame mounting plate (10); a sash mounting plate (11); a short arm (12) coupled by pivots at each end to the frame mounting plate (10) and the sash mounting plate (11); and an elongate long arm (13) coupled by pivots at each end to the frame mounting plate (10) and sash mounting plate (11), wherein the stay includes a first stop (33) and a second stop (102) acting as limiters at a fully open position of the window stay.

Abstract: A panel carriage hanger designed to travel slidable along a track, the panel carriage hanger having a cylindrical bore in a body, the bore having a lip substantially at a first end, the lip having a plurality of castellations. An anti-rotating sleeve having a plurality of castellations is located in the bore, and a biasing mechanism provides a substantially downwards force to the anti-rotating sleeve to mate the castellations. The anti-rotating sleeve movable substantially upwards from a first position in the bore where the castellations of the anti-rotating sleeve and the castellations of the bore mate such that the anti-rotating sleeve cannot rotate into a second position in the bore where the anti-rotating sleeve can rotate. A rod passing through and keyed to the anti-rotating sleeve such that the rod and the anti-rotating sleeve can rotate together, or both cannot rotate.

Abstract: A closure mechanism is described, the closure mechanism comprising: a base; a carriage movable along the base; a catching mechanism movable along the carriage; a first resilient mechanism connecting the base and the catching mechanism; and a second resilient mechanism connecting the carriage and the catching mechanism.

Abstract: A panel carriage hanger slidable along a track and having a body, rollers attached to the body to allow the body to travel along the track and a cylindrical bore in the body. The cylindrical bore has a lip including a plurality of castellations. The panel carriage hanger includes an anti-rotating sleeve inserted into the cylindrical bore, the castellations of the anti-rotating sleeve are mateable with the castellations of the cylindrical bore. The anti-rotating sleeve is movable from a first position in the bore where the anti-rotating sleeve can rotate in the bore and a second position in the bore where the castellations of the anti-rotating sleeve and the castellations of the cylindrical bore mate such that the anti-rotating sleeve cannot rotate.

Abstract: A processor (2) in a transaction processing system (1) has an event engine and a scenario engine. The event engine stores a framework (20) for each entity or type of service. The framework (20) has a parent class (21) and subsidiary classes (22-27). In real time the event engine instantiates an event object from a relevant class (22-27), giving it an effective time on a timeline of the parent class (21). The event objects many subsequently be handled as autonomous units for generation of reports or batch processing. The event engine moves the event objects between states of a finite state machine. A scenario engine also manipulates objects according to a finite state machine with future dates as the effective times. There is a state transition from the scenario environment to the event engine (live) environment.
