Patent GB-2127180-A (GB)
Title: Power assistance device
Inventor: HEMENS JAMES FREDERICK
IPC: F16H61/30
Filed: 1983-09-15
Abstract: A power assistance device has a double acting piston 15 and cylinder 14 whose piston rod 16 is connected to an output. Compressed air is passed via a pair of air pressure regulators 10a, 10b to opposite sides of the piston. Each regulator has a regulator spring 17a, 17b, and the regulators are housed in a body 10 which is moved upon manual effort being applied to an input to cause the springs to differentially bias so decreasing pressure on one side of the piston and increasing pressure on its opposite side, creating a pressure differential across the piston causing it to move with its piston rod to apply a magnified load to the output which is proportional to the manual effort applied to the input. The regulators could be set so that in a neutral position of the power assistance device, zero pressures exist on opposite sides of the piston. In an alternative arrangement a pair of single acting piston and cylinder devices could be used. Other gaseous fluids could be utilized, and a hydraulic fluid could also be used as the pressurized fluid medium. <IMAGE>

IPC: A23L15/00
Filed: 1986-06-17
Abstract: An omelette mix is prepared from a liquid egg product, which may be, for example, whole egg, egg white, egg yolk, a de-chloresterized or artificial mix, or any combination of two or more of the foregoing, by adjusting its pH, preferably with citric acid, then adding to it a hydrocolloid, comprising an alginate, adding a multivalent metal salt of only low solubility in water, e.g. calcium sulphate dihydrate, in order to facilitate any required cross-linking of the hydrocolloid molecular chains, mixing thoroughly to form a homogeneous material, forming this material into any desired shape and freezing or chilling it to produce a stable intermediate material that can readily be quickly heated to give an omelette in form ready for consumption. In general sodium chloride will be introduced into the mix, conveniently with the hydrocolloid, in order to enhance the flavour of the omelette. A sequestrant is desirably added to control the release of the multivalent metal salt and thus regulate the speed of the cross-linking reaction.

Filed: 1987-04-10
Abstract: A Golf Glove has three (or more/less) parallel lines stitched or printed onto its back which run from a point between the thumb and index finger and up to the top of the glove at the wrist to enable the user to place his/her hand in the recommended position. The underside of the golf glove is also colour coded or distinctively marked to provide the user with an indication as to where the club should lies across his/her palm and fingers. This colour coding or marking will also provide the user with a visual guide as to which fingers should exert more/less pressure to ensure a firm hold on the club. When all lines or markings are correctly aligned, the user will then realise that his/her grip is in the position favoured by the majority of professional golfers and hence 'correct'. <IMAGE>
