Title: Step stool having integral side storage compartments
Inventor: CALMEISE RANDALL W
IPC: A47C7/62
Filed: 1996-03-26
Abstract: A stepstool (10) is disclosed having a central planar top platform (14), four support legs (20,22,24,26), and a pair of storage receptacles (36,38) extending outward in cantilever fashion from opposite sides of the stool.

Title: Apparatus for limiting supply of electricity to a consumer
Inventor: PAYNE KENNETH
IPC: H02H9/02
Filed: 1996-10-18
Abstract: Apparatus for controlling the supply of electricity to a consumer comprises first and second current supply paths respectively through low W1 and high W2 impedance windings of a dual winding magnetic relay, with normally closed contacts 14 of the relay in the first current supply path, wherein the impedance of the first path is such that, in use, the magnetic field produced by the current in the relay coil W1 causes the relay to operate to open the contacts 14 when the current drawn by the consumer circuit exceeds a predetermined level, whereafter a much smaller current flows to the load through the higher impedance winding W2, which is just sufficient to keep the coil energised and to keep the contacts 14 open.
Patent GB-2318562-A (GB)
Title: Drinks can with carbonating means
Inventor: GREENER JUSTIN WILLIAM
IPC: B65D85/73
Filed: 1996-10-25
Abstract: A drink can lid with standard ring-pull has an actuating mechanism on the outer surface of the lid which, when activated, causes the release of Carbon Dioxide, or other gas, into the contents of the can from a capsule within the can. The activation of the mechanism on the outer side of the lid is optional and the contents of the can could therefore be consumed as either a "still" or "sparkling/carbonated" product.

Title: System, method, and compiler pre-processor for conditionally compiling a software compilation unit
Inventor: UNNI SHANKAR
IPC: G06F9/45
Filed: 1995-08-02
Abstract: A system, method, and compiler pre-processor (114) for conditionally recompiling a compilation unit having a plurality of source code modules operate by selecting one of the source code modules, and determines whether it is necessary to generate a new condensed representation of the selected source code module. A new condensed representation of the selected source code module is generated if such generation is determined as being necessary. Changes between the new condensed representation of the selected source code module and an old condensed representation of the selected source code module are identified. Each of these changes is classified as either a compatible change or an incompatible change (926). An incompatible change is a change that requires recompilation of the compilation unit. A compatible change is a change that does not require recompilation of the compilation unit. The compilation unit is recompiled if any of the changes is classified as being an incompatible change (816).

Title: Mobile phone with character enlarging for in-car use
Inventor: TOBA HIROYUKI
IPC: H04W88/02
Filed: 1997-04-11
Abstract: A mobile phone contains a circuit 2 for detecting when it is connected to a vehicular adaptor. In response to an off hook signal from a hook detecting circuit 7, and under the control of the on-vehicle detecting circuit, a selection control circuit chooses the appropriate character size for use with the telephone's display unit (figs.2A,2B). The selection control circuit is arranged so that if the phone is plugged into the vehicular adaptor, the characters are enlarged for easier reading, the degree of enlargement being preselectable by the user. Removal of the phone from the vehicle causes the displayed characters to return to normal size.

Patent GB-2319092-A (GB)
Title: Deadweight calculating apparatus for a vehicle with anti skid means
Inventor: NAKAZAKI YOJI
IPC: G01G19/08
Filed: 1997-10-28
Abstract: Apparatus is provided for calculating the deadweight of a vehicle that has start assisting means 41 to increase the load over the drive wheels in order to increase the traction between the drive wheels 15 and the road surface and prevent skidding of the rear wheels 15 when starting on a slope or with insufficient drive wheel loading. Activation of the start assisting means 41, either in response to load sensors or a manual switch, would cause the load sensors to provide an incorrect reading of the deadweight of the vehicle, so detection means are provided to detect whether the start assisting means are in operation so that calculation interrupting means can act to interrupt calculation of deadweight during the period of operation of the start assisting means 41. The deadweight of the vehicle may be displayed to the driver in real-time until operation of the start assisting means, when the displayed deadweight is fixed at the value displayed before operation of the start assisting means 41. Visual and audible alarms may be provided to indicate when the start assisting means are in operation and when the vehicle is overloaded.

Patent GB-2336175-A (GB)
Title: Liquid mixing apparatus in greywater recycling system
Inventor: GEDDES BRUCE DONALD
IPC: E03B1/04
Filed: 1998-02-06
Abstract: A mixing tank which forms part of a greywater recycling system contains a float chamber 43, a funnel 44 and two siphon tubes 45, 46. Siphon tube 45 provides liquid communication between the interior of funnel 44 and the float chamber, tube 46 between the funnel 44 and the mixing tank. The mixing tank, connected to a supply of mains water via a valve 41 and ballcock 42, holds a dilute solution of chemical for disinfecting greywater stored in a sump (10, figure 1). When the mixing tank is full, disinfectant may be drawn off as required via outlet 48 and fed by gravity to the sump. When the level in the mixing tank is low enough (figure 3b) a float switch (49) activates causing a measured amount of chemical concentrate to be deposited in float chamber 43 via funnel 44; this concentrate then flows into the mixing tank by a siphoning action (figures 3c and d). When the level of liquid in the float chamber drops to a level where the siphons are broken (figure 3e) the ballcock shown in the drawing activates the water mains to supply water to the mixing tank and by overflow to chamber 43. Three other inventions disclosed are a valve comprising an expandable bladder (Figures 5a-c), a liquid metering apparatus (Figures 4a-d) and a filtering means (Figures 2a-b).

Title: Ground-gripping elements for shoe soles
Inventor: COLLINS DAVID ROY
IPC: A43C15/16
Filed: 1998-03-05
Abstract: A moulded plastics golf shoe cleat comprises a disc 14 from an upper surface of which a screw-threaded spigot (not shown) projects for attachment of the cleat to a shoe sole. A ring of barb-forming elements 16 stands on an undersurface 18 of the disc, each element comprising a convergent free-end portion forming a ground-engaging barb which terminates at an edge 24 extending tangentially of the ring. Each barb projects in a direction which makes an acute angle with the undersurface 18 of the disc 14, the barbs being resiliently deflectable to increase the angle whereby resistance to sliding of the cleat in use over penetrable ground may become increased by increased penetration of the barb into the ground. The barbs are aligned along chords to the ring, being uniformly turned out of radial alignment so as to discourage unscrewing of the cleat in use.

Title: Optimising system resources in an object-oriented environment
Inventor: MCNAMARA MATTHEW
IPC: G06F9/44
Filed: 1998-06-26
Abstract: In an object oriented environment, optimising the use of system memory by making sure that all sub-objects of a released object are also removed from memory. As each object for which sub-objects exist is created in memory, it is encoded with a container register and an object stack is initialised. When an object is released and should be deleted from system memory: a driver object is opened, 10; a list of sub-objects for the driver object is created, 11, and indexed to the stack, 12; the stack is then iteratively and sequentially read, 13, to check whether an object container register exists, 14; if it does, that object is opened, 10 and its sub-objects are indexed to the stack; finally, the stack is processed to delete all referenced objects. A three tier client server model is simulated (fig. 2), in which the class structure of the middle tier is retrieved from a database table, allowing automatic amendments to the structure without the need for code modifications and testing, reducing development time and costs.
