Patent GB-2202979-A (GB)
Title: Rotating mechanical index
Inventor: ASHFORD LESLIE ERNEST THOMAS
IPC: G06M3/12
Filed: 1987-04-02
Abstract: In a rotating mechanical index such as used in a gas meter and having an index pointer 12 rotatably driven in one direction, a pawl 15 which is inoperative during rotation of the pointer in the normal direction disengages the pointer from its mounting when it is driven in the reverse direction to indicate a fraudulent attempt to reverse the operation of the meter. The pointer 12 which normally slides over the back of an extension of a horseshoe shaped pawl 15 engaged in a stationary structure 11 is stopped by the extension in reverse rotation as to be disengaged from its mounting. In an alternative arrangement, the movement of the pawl causes the end of a lever to obstruct the pointer making it fall off its mounting. The end of the lever also becomes visible to provide a further indication of attempted fraud. The pawl may also bear a flag which becomes visible with reverse rotation of the index. <IMAGE>

Title: Printed transfer sheet for fabric decorating
Inventor: D OLIVEIRA AMANDA UCHOA
IPC: D06P5/24
Filed: 1987-04-24
Abstract: There is provided a method of producing a patterned substrate from which fabric may be decorated wherein a pattern produced using a suitably programmed computer is printed onto a substrate from which fabrics may be printed, the pattern being printed on the substrate by means of a computer-linked printer, e.g. an ink jet printer in which transfer dyes are used. Using this technique, fabrics, especially hosiery, can be produced having a diverse range of patterns and the overall production process is greatly shortened and is less costly for the small producer.

Title: Marine survival system
Inventor: WILKS THOMAS MORETON
IPC: B63B23/00
Filed: 1987-11-11
Abstract: On launch of a lifecraft (14) from a marine platform (10) or other vessel, an electrically powered tug (20) connected to the lifecraft (14) by stowed cable (22) aligns the lifecraft (14) away from the platform (10) and tows it away from the platform (10) in a predetermined attitude and track. In this way, the lifecraft (14) is controlled in the hazardous initial period between launch and start of its own powered movement. The tug (20) is advantageously stowed and launched bows-out and has station-keeping means responsive to deviation of the towline (22) from the tug fore-and-aft line to correct the tug helm so that the tug (20) not only follows a predetermined compass heading but follows a predetermined track relative to the lifecraft (14). A portion of the towline (22) is stored in retractable payout means biased towards towline retraction so that the towline (22) is paid out as the tug (20) is lowered and retracts into the tug (20) during initial movement of the lifecraft (14) with the tug (20) still in the water and acting as a sea anchor.   <IMAGE>

Patent GB-2207001-A (GB)
Title: Inertia sensor
Inventor: CROFT MARTIN ALAN
IPC: H01H35/14
Filed: 1988-06-06
Abstract: An inertia sensor comprises a conductive inertia body (22) movable in a chamber when accelerated or tilted beyond a certain angle, to bridge contacts (12, 13). The contacts remain bridged when the chamber is upside down, because a deflector (part of contact (13)) deflects the body (22) to the bridging position. The chamber floor (21) is depressed to define a rest position for the body (22). A second inertia body (25) bridges the same contacts, but not when the chamber is upside down (due to a domed contact portion (26)). The two bodies jointly ensure bridging of the contacts (12, 13) over a very wide angle of tilt. In an alternative arrangement, a chamber is defined between top and bottom walls comprising different parts of one contact, the second contact being annular and part-way between the walls. The bottom wall defines the rest position and the top wall the deflector. Magnetic biasing can be used. <IMAGE>

IPC: B01D39/04
Filed: 1991-05-17
Abstract: A porous filter medium is tested 10 determine its wetting characteristics using a series of liquids of progressively increasing surface tensions. Drops of the liquids are applied to different parts of the medium until two liquids of different, but adjacent in the series, surface tensions are found, one of which is absorbed by the medium while the other is not. The medium is then considered to have a critical wetting surface tension (CWST) midway between the surface tensions of two liquids. Typically ten drops of each liquid are applied, and liquid is regarded as absorbed or rejected if after ten minutes nine out of ten drops are so absorbed or not.
