Patent GB-2255180-A (GB)
Title: Soft sonar suspension system
Inventor: PAKKER ULRICH
IPC: G01N27/414
Filed: 1992-04-01
Abstract: An underwater transducer assembly (T) is mounted on an elongated cylindrical piston (32) received in a pneumatic cylinder (31). One or more springs (41) normally bias the piston (32 or 90) inward into the cylinder (31) to retract the transducer assembly (T) into a sea chest (S'). Air under pressure introduced into the cylinder (31) is effective to overcome the force of the springs (41) and project the transducer assembly (T) to a position operative for scanning. Force applied to the transducer assembly (T) tends to move the piston (32) inward into the cylinder and thereby increase the pressure of the system. The transducer assembly (T) is retracted automatically if the pressure exceeds a predetermined pressure. A separate mechanical sensor is mounted adjacent to the sea chest S' to detect the presence of obstacles or debris and automatically actuate retraction of the transducer assembly (T). <IMAGE>
Patent GB-2266702-A (GB)
Title: Beverage dispense point
Inventor: BENNETT NICHOLAS PAUL
IPC: B67D1/14
Filed: 1992-05-09
Abstract: At a dispense point beverage, e.g. beer, flows from nipple 1, Fig. 1, to flow straightener 3 via a gas-releasing, head- forming cap 7 located on the nipple or straightener. Mount 5 is screwed to nipple 1, so that manual mount rotation axially moves the straightener, and possibly cap 7, to vary the gas-releasing effect. Nipple 1 has lugs 21, Fig. 2, co-acting with straightener catches 23 to limit rotation, and thus adjustment, in both directions. Lugs 21 are deflectable, using severe hand pressure or a tool, to allow further rotation. Alternatively (Fig. 3, not shown) cap 7 is located on an oval mount 5 with an oval straightener 3. Co-action between the oval mount ends and the straightener wall limits relative rotation, although the straightener may be flexible to allow further forced rotation. <IMAGE>

Title: Colouring pigment from synthetic magnetite
Inventor: OULSNAM BRYON THOMAS
IPC: C09C1/24
Filed: 1994-02-11
Abstract: Colouring pigment of comparable quality to, and cheaper than, pigments products by chemical precipitation, is made from synthetic magnetite produced by oxidation of ferrous mill scale and reduced to a particle size such that preferably at least 85% of the product does not exceed 10 microns and 95% does not exceed 20 microns. The smaller the particle size the greater the tinting strength of the pigment. The pigment may be black or, by calcination of the synthetic magnetite, it may be red. For best quality black the pigment should contain 95 - 99.5% iron oxides, typically, and the magnetite should have a molecular ratio of 0.9 to 1.1:1. The shade and hue of red is dependent upon the calcination temperature and final size and shape of the particles. Reduction to the required particle size for the red colouring pigment may be done before and/or after calcination.
