Title: Protective covers for 2-axis machine tool
Inventor: BARTLETT CHRISTOPHER DAVID
IPC: B24B55/00
Filed: 1994-08-01
Abstract: A machine tool comprising: a machine frame; a work carrying assembly for carrying a workpiece, carried by said machine frame for reciprocal movement along a work axis; and a cover assembly carried by said machine frame and including cover portions disposed to cover selected areas of said machine frame proximate said work axis. The cover assembly is not connected to the work carrying assembly but is operable to effect movement of said cover portions commesurate with movement of said work carrying assembly. The work carrying assembly includes a work carriage and said machine frame mounts a slideway proximate said axis and extending in the same direction as the work axis. The work carriage extends in the direction of said work axis but is of lesser extent than said slideway such that portions of said slideway to either one, the other or both extremities of said carriage assembly may be exposed upon said reciprocal movement of said work carrying assembly work carriage. The cover portions cover the slideways that may so be exposed. A first cover is disposed to cover the slideway to one side of the work carriage and a second cover portion is disposed to cover the slideway to the other side of the work carriage. Each cover portion includes a plurality of telescoping, slidably interrelated covers which are moved with respect to each other to cover more less of said slideways as such becomes or become covered by the work carriage. <IMAGE>

Title: Manufacture of Smoke Alarms
Inventor: BYRNE MICHAEL
IPC: B29C48/07
Filed: 1996-02-26
Abstract: A process (1) for producing smoke alarms has the step (2) of injection moulding polystyrene to form casing components in which there is an antistatic concentrate added at a proportion in the range of 1 to 10%. Static build-up on components is also reduced by ionisation of ambient air, and maintenance of a relative humidity of greater than 60%. An integrated circuit coupled to a smoke sensor has an input lead connected off-board to maintain a high input impedance. A conformal coating is also applied around the integrated circuit to help maintain a high impedance in the field. There is multiplexed functional testing for efficiency in which test fixtures have independent power supplies and the clock speed of the smoke alarms is increased to improve cycle time. The coating is around the integrated circuit input lead to maintain an impedance greater than 10 14 ohm.

Title: Practice golf tees
Inventor: HAGELTHORN DAVID PETER CLEMENT
IPC: A63B57/00
Filed: 1996-11-07
Abstract: A practice golf tee assembly has a platform (6) up through which a tee (7) carrying a golf ball is projected under the player's control. The tee (7) is raised and lowered by a cam (11) rotated by an electric motor (13) energised when a pressure pad (4) on the platform (6) is pressed. The power circuit is automatically broken when the tee (7) is raised, leaving a ball proud and ready to be struck. After striking, the player presses the pad (4), using his club, and the power may then be latched on by the cam, allowing the pad (4) to be released. A golf ball is gravity fed to the tee (7) when that is fully lowered below the platform, and when it may be automatically arrested requiring further operation of the pressure pad (4) to bring the tee up again.

Title: Dross processing apparatus with a vibrating skim box
Inventor: POWNALL MICHAEL
IPC: C22B7/04
Filed: 1997-07-24
Abstract: The apparatus comprises a skim box 30 for holding a quantity of hot aluminium dross 32 and a press head 20 for squeezing aluminium from the dross 32 held in the skim box 30 into a mould box 40 below. To increase the yield of aluminium from each load of dross 32, the skim box 30 is vibrated by vibration means 302-324. The vibration is preferably performed by subjecting the skim box 30 to sharp vertical movements to assist in the downward movement of aluminium towards a drainage hole 31 situated in the bottom of the skim box 30. In the figure, vibration is created by reciprocating hydraulic cylinders 322 and 324, however the vibration could be created by other means such as pneumatic cylinders, an electric eccentric counterweighted motor or rotary cam and follower or by using ultrasound.

Title: CATV slot allocation using dynamic search tree expansion
Inventor: CITTA RICHARD W
IPC: H04N7/173
Filed: 1997-12-18
Abstract: A CATV communication system has stations which communicate data in a data frame having a plurality of slots, wherein the plurality of slots are new message minislots NMS, expansion minislots EMS, and data slots DS. A master station determines a range parameter R which is based upon a number of slave stations transmitting reservation requests in a data frame. The master station also determines a parameter MAP according to a number of reservation requests in a queue waiting to be processed by the master station. The parameter MAP defines the new message minislots, the expansion minislots, and the data slots in an upstream data frame. The master station transmits the range parameter R and the parameter MAP to a plurality of slave stations. Each slave station independently determines a random transmission parameter RN. Each slave station transmits to the master station (i) a new reservation request in a new message minislot if its random transmission parameter RN corresponds to the parameter MAP, (ii) an old reservation request in an expansion minislot if assigned an expansion minislot in the parameter MAP, and (iii) data in a data slot if assigned a data slot by the master station.

Title: Strap retainer
Inventor: ANSCHER JOSEPH
IPC: A44B11/04
Filed: 1998-06-08
Abstract: A strap retainer comprising a flexible elongated body having two planar sides and two free ends adapted for closure on to each other. A locking pawl 30 is integrally formed with one free end and comprises a post and a head section 31. A receptacle 20 for the locking pawl is integrally formed with the other free end. The receptacle has top and bottom surfaces that are parallel to the planar sides of the body. A cavity 21 in the top surface of the receptacle has an enlarged section and a narrow section 22. There is at least one flexible locking tooth 40, that protrudes into the cavity. A shoulder element 23 is arranged on each side of the cavity to define an insertion area in the top surface of the receptacle corresponding to the shape of the locking pawl. Inserting the locking pawl into the cavity through the insertion area depresses the locking tooth, and sliding the locking pawl toward the free end of the receptacle releases the locking tooth and locks the locking pawl in the receptacle beneath the shoulder elements.

Title: Updating applications incrementally
Inventor: AYRES MALCOLM DAVID
IPC: G06F9/445
Filed: 1998-09-12
Abstract: A method of updating a first version of an application file installed on a client computer to a second version comprises the steps of: responsive to receiving a delta file defining file changes, transforming the first version into a first transform comprising a series of records; applying the changes defined by the delta file to selected ones of those records to generate a transform of the second version; and reverse-transforming the latter transform to generate the second version of the application file. The use of the delta file minimises the amount of data that needs to be downloaded from a server to the client computer across a network (e.g. the Internet). The application may comprise Java class files.

Title: A method for forming a compact
Inventor: OBA TAKESHI
IPC: B29C43/02
Filed: 1998-12-22
Abstract: A method of forming a compact 1 through which at least one hole 1a passes, by placing a core 13 and either a pre-compressed compact or powder P in a die 30-32 (Fig. 6c) and compressing by means of a punch 34 inserted into the die 30-32 to apply pressure along a direction which is crossed by the core 13 (Fig. 6d). The resulting compact 1 and core 13 are drawn out of the die (Fig. 6e), then core 13 is drawn out of the compact 1. As the core 13 does not engage with the die 30-32 it is not loaded and is therefore not transformed or broken by the compaction pressure. Optionally the core 13 may be held in place by means of a pair of jigs 36 and the compact 1 may be made from a plurality of pre-compressed compacts which are bonded together as a result of the pressure. The same method can also be used to make compacts that have abutments or grooves rather than holes.
