Patent GB-2052428-A (GB)
Title: Infusion bags
IPC: B65D85/812
Filed: 1980-05-02
Abstract: An infusion bag, e.g. a tea bag, is connected to a holder (7) by a filament (6), the bag being closed by folding over its open end which is then bonded over a region (4) to seal the end closure, secure one end of the filament and form a pocket (8) in which a portion of the holder is releasably held, and the holder being formed with a cavity (9) in which almost the entire length of filament is accommodated. The filament is arranged in zig-zag form in the holder. Individual holders accommodating filaments are separated from a strip formed by enclosing a continuous filament between two webs which are joined to one another to define the pockets and secure the filament. Accommodation of the filament in the holder which is received in the pocket on the infusion bag prevents tangling when stored with similar infusion bags provided with filaments and holders. <IMAGE>

Title: Improved surface treating machine
IPC: B24C3/06
Filed: 1981-01-29
Abstract: In a surface cleaning or surface removing machine a blast wheel (5) projects abrasive grit (6A) at the surface (4) through a blast opening (2).

Title: Improvements in power- operated boosters
IPC: B60T13/14
Filed: 1981-04-21
Abstract: A booster for a vehicle braking system has an input piston (3), a boost piston (6) and an output piston (112) (Fig. 9) working in a bore (2), the boost piston (6) being advanced in the bore (2) in response to pressure fluid from a source pressurising a boost chamber (5) under control of valve means. In order to pressurise the braking system to a threshold level in which lost-motion in the system is taken up, in response to an initial pedal movement, the operation of the valve means is dependent on the pressure in the system, and the valve means has a valve mechanism (20) working in a bore in the boost piston (6) of which one part (50) has a pressure- responsive face in chamber (30), the valve means being operative, on initial movement of the input piston (3) to cause pressurisation of the braking system to the threshold level, and application of pressure fluid to the pressure-responsive face to move the part (50) relative to the input piston (3) to place the boost chamber (5) in communication with the pressure source and close the seal 67. Threshold pressurisation of the braking system may be achieved by pressurisation of the boost chamber (5), or an auxiliary chamber (119) (Fig. 9) forward of the boost piston (6) to a predetermined level. <IMAGE>
