Filed: 1971-12-03
Abstract: 1360790 Frame joints and members BRITISH ALUMINIUM CO Ltd 3 Dec 1971 [23 Dec 1970] 61151/70 Heading E1J Connector elements 14 or 26 have two outer, opposed grooved surfaces (not shown) and at least one slot 20 or 29 extending between faces of the element, at least one of which faces is a grooved face, so as to define prongs on the elements sides which are outwardly deformed so as to grip the inside of a tubular window or door frame member 27A when inserted therein. The element may be L-shaped Figure 9, for forming corner connections, or have only one limb bolted to the side of a frame member 27B to form a T connection. The grooves and slots are preferably filled with a self curing resin prior to insertion, the joint then being held in position whilst localized heating is used to cure the resin. The ends of the prongs may be bevelled to assist insertion. The grooves preferably extend normally to the frame's longitudinal axis and the distance between such surfaces is slightly less than the internal dimensions of the frame. The frame elements may be of plastics or metal but are preferably of aluminium or aluminium alloy, as are the connector elements. The frame may be in two longitudinally separated parts 32, 33 interconnected either by a thermally insulating plastics 34 or merely by the connector elements 14 or 26.
Patent GB-728720-A (GB)
Abstract: 728,720. Fluid-pressure servomotor-control systems. HERMANNS, E., and KAISER, W. May 6, 1953 [May 14, 1952], No. 12634/53. Class 135. The supply of gas to a gas-burning appliance is controlled by a valve having a gas inlet 1 and an outlet 2 to the burner, the flow between which is regulated by a valve closure member carried by a flexible diaphragm 5 clamped between the valve body and a head 20. The body is formed with inner and outer grooves 7, 8 communicating through holes in the diaphragm with corresponding grooves in the head, and the flow of gas from the inlet 1 to the inner groove of the body is controlled by a manuallyoperated valve 9 connected by a pipe 6 with the inlet and through a duct in the body with the groove. The corresponding upper groove is connected by a continuation of the duct 6 with the space beneath a bimetallic disc 10 having a hole 11 at which a pilot jet burns when the valve 9 is opened. The outer groove in the body is also connected with the inlet 1 through a duct 12 and the corresponding groove in the head communicates with a space 13 from which the gas flows through ports 19 and thence through ports 17 controlled by a spring-closed valve 15 to the space beneath the disc 10. In operation, manual opening of the valve 9 permits gas to flow through the duct 6 to the space beneath the disc 10 and to be ignited at the hole 11. The heat of the flame causes the disc to flex downwards and open the valve 15 so allowing gas to flow through the ports 17 from the space above the diaphragm 5. At this stage, the valve 9 may be allowed to close and the reduction in gas pressure above the diaphragm permits the closure member carried thereby to open and allow gas flow from the inlet 1 to the outlet 2.

Patent GB-2010706-A (GB)
Title: Centrifuges
IPC: B04B13/00
Filed: 1978-07-12
Abstract: A centrifuging system is described in which the centrifuge is located in a container which can be sealed by means of a lid. Means is provided for supplying to the container an inert gas for purging the container and centrifuge of all oxygen and other combustible gases/vapours etc. before a centrifuging action to reduce the risk of explosion during a centrifuging action. Control means determines when a predetermined volume of gas has been purged through the equipment and an interlock provides that the purging process must be gone through completely before the centrifuging action can be begun. To this end the supply of material to be centrifuged is prevented until the complete purging process has been completed. The purging cycle is reset upon opening of the lid. An alarm is provided to indicate if the flow of gas to the container/centrifuge falls below a predetermined flow rate. A small positive pressure is maintained in the container during centrifuging and an alarm is provided to indicate if this small positive pressure drops. A second purging flow of inert gas is induced after the centrifuging action. In an alternative system the venting gases are analysed on an in-line basis and the centrifuging action including the supply of material to be centrifuged is inhibited until the analysis indicates the level of oxygen to be below a given concentration. A warning signal is generated in the event that the oxygen level increases above a given level during the centrifuging. An interlock may be provided to cut-off the supply of material to the centrifuge if the small positive pressure drops during centrifuging. <IMAGE>

Patent GB-2008496-A (GB)
Title: Inking apparatus
IPC: B41F31/06
Filed: 1978-12-11
Abstract: The invention relates to a printing machine and in particular an inking assembly used therein, the inking assembly being an ink-containing trough 21 with a pick-up roller 22 associated therewith, a print roller 24, and a transfer roller 27A or 27B, for transferring a film of ink from the pick-up roller to the print roller. The transfer roller is mounted for limited axial movement e.g. by an arrangement such as a rotary cam at one and acting against a biasing spring such that axial oscillation of the transfer roller takes place during use of the machine. Such oscillation of the transfer/roller applies a brushing movement to the ink as the latter is applied to the print roller and avoids streaking or lining which is liable to occur where the rollers are capable of relative rolling movement only. <IMAGE>

Patent GB-2027536-A (GB)
Title: Improvements in gas-fired appliances
IPC: F23N5/10
Filed: 1979-07-25
Abstract: A gas-fired appliance, such as a gas cooker, has a clock (16) which after a predetermined time provides a signal which produces a voltage of opposite polarity to that produced by a flame detector (14) to close a gas supply valve (3). The clock can be set to switch on the gas supply to a burner (1) at a first selected time, and at a second selected time either to switch off the gas supply to the burner or to reduce the level of the gas flow, for keeping cooked food warm. The setting of a manual switch (39) determines whether the gas supply is shut off or is merely restricted at the second selected time. A capacitor (22) is charged up after the first selected time, and at the second selected time a switch arm (19) controlled by the clock moves to discharge the capacitor either through a solenoid (11) energised by the flame detector (14) in order to de-energise that solenoid (11) to switch off the gas supply, or through a relay (24) which energises a solenoid (10) to restrict the gas supply. <IMAGE>
