Patent GB-2202973-A (GB)
Title: Timeswitches
Inventor: PALMER MALCOLM WILLIAM THOMAS
IPC: G05B19/042
Filed: 1988-03-30
Abstract: A programmable timeswitch comprises a microcontroller (1) and a switching relay (4) for controlling the supply of electricity to electrical apparatus in accordance with a predetermined 'yearly' programme stored in an EPROM (2). The yearly programme can include different daily programmes for weekdays and weekends and includes different seasonal programmes to take account of different demands for electricity at different times of the year. The timeswitch is programmed to switch automatically from one seasonal programme to the next seasonal programme on predetermined dates in the year and so does not have to be re-programmed at intervals throughout the year. The timeswitch may be used as part of a 'deferable load programme' run by a utility in which a large number of timeswitches are supplied to different installations, the timeswitches having been programmed by a master console under the sole control of the utility. <IMAGE>

Title: Heat-proof casings for electrical equipment
Inventor: KNIGHT PETER DAVID
IPC: G11B33/12
Filed: 1991-02-25
Abstract: A heat-proof casing 1 is provided for a tape recorder for monitoring electrical signals generated on board ship in an emergency, the casing 1 being releasably connected to a cradle 2 which is mounted on the deck 3 of a ship. The casing 1 comprises an inner chamber 20 accommodating the tape recorder 21 which is to be shielded from the effects of external heat, a duct 24 for electrical wiring 23 extending from the tape recorder 21 within the inner chamber 20 to the outside of the casing 1, and an inner jacket 27 surrounding the inner chamber 20 and having hollow walls filled with paraffin wax 31. The paraffin wax 31 is in the solid state at normal ambient temperature but changes to the liquid state when subjected to external heat above a certain level and thereby absorbs external heat. Thus the tape recorder 21 is shielded to a substantial extent from the effects of external heat, generated by a fire on board ship for example. <IMAGE>
Patent GB-2255087-A (GB)
Title: System for cleaning contaminated water
Inventor: GILLHAM ROBERT WINSTON
IPC: C02F1/28
Filed: 1991-04-25
Abstract: Water contaminated with halogenated organics, including chloroform, trichloroethane, solvents, pesticides, etc. is treated by passing the water through a permeable mixture of activated carbon and iron fillings. When the mixture is brought to a negative Eh voltae, the metal causes the contaminants to undergo chemical breakdown. The activated carbon acts to retard the contaminant, giving it a long residence time close to the iron. The negative Eh conditions demand oxygen exclusion, such that a favoured application is to place the mixture in a trench below the water table in an aquifer, in the path of a plume of contaminant. The mixture may also be contained in a tank above, or in, the ground. An inert filler material, such as sand, may be included in the mixture.

Title: Welded optical fibre interface to a silica intergrated optic device
Inventor: ALLEN JAMES JOSEPH
IPC: G02B6/30
Filed: 1992-01-10
Abstract: In accordance with the present invention the material similarity of all-silica waveguides or other devices and optical fibres is utilised to establish an epoxy-free fusion interfacing between optical fibres and integrated-optic devices by using laser welding techniques. This is uniquely applicable to all-silica integrated devices since they have virtually identical material properties to those of optical fibres. The method comprises the steps of machining a locating groove in a silica block, fixing a prepared length of the optical fibre in the locating groove, bringing the block and the device into juxtaposition and aligning the block and the device to provide maximum transmission of a signal from the fibre to the device and laser welding the block and the device together.

Title: Square root anti-symmetric filters
Inventor: DREWERY JOHN OLIVER
IPC: H03H17/02
Filed: 1992-02-13
Abstract: A filter is produced having a real and an imaginary part, such that for positive frequencies the frequency characteristic F of the filter is F = A + jS. The real part A is a skew-symmetric filter and S is a real symmetric filter symmetric about the cut point. S is related to A by S =  2ROOT [A(1-A)]. Once A has been chosen the filter can be derived. A method of forming the filter involves deriving symmetrical and antisymmetrical windows from the filters frequency characteristic A and S and combining the windows to form an asymmetric window.

Title: Automatically releasing door handle snib
Inventor: NUGENT WALTER JOSEPH
IPC: E05B13/00
Filed: 1992-07-15
Abstract: A snib mechanism for a door latch and handle assembly is arranged to be automatically released on rotation of the internal door handle. The external handle 5 is mounted on a shaft 8 which carries at its inner end a rotatable member 14 having a peripheral notch 44. Member 14 also carries a pin 82 whereby rotation is transmitted to inner handle and vice versa via a slot 80 on member 12 attached to the shaft of the inner handle 6. The snibbing member 42 is pivotable by thumb piece 47 to engage the notch 44 thus preventing movement of the external handle. However, on rotation of inner handle, member 12 rotates through the lost motion of slot 80 (ie without driving the external handle), and disengages the snib member, lifting it out of the notch 44 by pin 86 on the snib riding up cam surface 84 of member 12. Further rotation of the inner handle then drives the main shaft 8 and disengages the door latch. Pivoted lever 62 may be provided to allow for emergency release of the snib member by insertion of a screwdriver and the like in opening 70 provided in the outer cover 23. <IMAGE>
