Title: Method of repairing furnace roofs during heat-up
IPC: F27D1/02
Filed: 1978-10-19
Abstract: A method for preventing the dropping of individual bricks (20') from a sprung arch roof (11) employed in a continuous tank-type glass melting furnace, the dropping of the bricks normally occurring during heat- up of the furnace. The slightly tapered bricks (20) employed in constructing the roof are oriented with their long axis in the vertical direction and, as heating occurs and the structure differentially expands and the bricks dry out, some become sufficiently loose to drop from the roof into the tank of the furnace. In visually observing the interior surface of the roof during heat-up, it can be seen which bricks are settling and likely to drop therefrom. These bricks are pulled up through the roof from above by a suction cup and mortar is placed around the bricks. The bricks are then dropped back into place with the mortar holding the bricks until they become wedged firmly in place as the temperature of the roof increases. <IMAGE>

Title: Vehicle occupant belt with a movable- lockable anchor
IPC: B60R22/06
Filed: 1979-06-08
Abstract: A passive vehicle occupant restraint belt system comprises a movable anchor 8 which is moved by a driven transfer element e.g. wire 13 drawn by motion amplifier 14 along a guide rail 9 between a release location corresponding to the occupant-releasing configuration of the belt and a restraint location corresponding to the occupant- restraining configuration of the shoulder belt 1.

Title: Process for separating optical isomers of cyclopropane carboxylic esters
IPC: C07C51/487
Filed: 1979-10-05
Abstract: A process for separating the individual optically active isomers of cis- or trans- cyclopropane carboxylic acids which comprises the step of treating an aqueous solution of a soluble salt of the racemate or diastereoisomeric mixture with just sufficient of a suitable optically active amine to cause precipitation of one isomer or diastereoisomer of the cyclopropane carboxylic acid as the amine salt, whilst substantially all of the other isomer (or isomers if more than two are present in the mixture) remains in solution as the soluble salt. The process can be used to separate (+)-cis- 3-(2-chloro-3,3,3-trifluoroprop-1-en-lyl)- 2,2-dimethylcyclopropane carboxylic acid from a (+/-)-cis- mixture.

Title: Control system for gaming machines
IPC: G07F17/32
Filed: 1980-11-13
Abstract: A fruit machine has at least one randomly available feature by which the player can adjust the positions of the reels in addition to the normal spin, and so increase the chances of a win in that game. In order to stabilise the machine's win/loss ratio, a comparison is continuously made between the money or tokens paid in and that paid out in occasional prizes. When the balance tends in favour of the machine winning more than a given amount, the availability of the feature is increased, and vice versa.

Title: Apparatus and Method for Generating an Alpha Numeric Output from Shorthand
IPC: G06K9/48
