Patent GB-1546665-A (GB)
Title: Motor control systems
IPC: E05F15/00
Filed: 1976-05-21
Abstract: The control device is allocated to a DC motor which can rotate in opposite rotation directions and is used as a drive for components which can move into two limit positions, especially for opening and closing garage doors. In this case, switching devices (10, 16) are provided for the DC motor, which switching devices switch said motor off and on and/or reverse the direction of the motor current and hence the rotation direction of the motor. An overcurrent switching appliance (12) trips in response to current surges which occur when the load on the motor increases, especially during forced braking of the motor in the limit positions of the component or if an obstruction is present in the movement path. The switching devices (10, 16) have an on/off switch (16) and a switching appliance (10) which operates in a stepped manner and can be switched into an "interrupt" switching position whenever the overcurrent switching appliance (12) trips and into a "motor current on" switching position whenever the on/off switch (16) is operated, in accordance with the following switching cycle: interruption - motor current on and anticlockwise running - interruption - motor current on and clockwise running. As a result of this arrangement, limit switches are obviated and hence their adjustment and maintenance work. At the same time, reliable protection against overloading the DC motor is achieved. <IMAGE>

Title: Improvements relating to the formation of powders by drying
IPC: B01D1/18
Filed: 1947-08-07
Abstract: <PICT:0634467/III/1> Moist or liquid materials containing solids are dried with hot air in two or more stages, the first of which is a spray-drying stage wherein sufficient moisture is removed from the material to reduce it to the form of non-coherent solid particles. The hot air is introduced into the last stage and passes successively through the stages in the opposite order to that followed by the material being dried.  Liquid material to be dried is sprayed into the top of tower 10 and is met by warm air introduced through pipe 13 from drying chamber 11.  The spray is partly dried by the air and settles in the base of the tower as non-coherent solid particles with a moisture content of from 10 to 20 per cent.  The now cooled and damp air leaves tower 10 through duct 14.  The solid particles are conveyed from tower 10 to the top of drying chamber 11 by powder fan 15.  Fresh hot air, from heater 17, is also introduced into the top of chamber 11, and further dries the particles to a moisture content of about 6 per cent.  These are collected in hopper 20 and conveyed by powder fan 21 to cooler 22.  The partly-cooled but still warm air passes out of chamber 11 through pipe 13, and enters tower 10.  Air withdrawn from cooler 22 passes through pipe 23 to join the effluent air from tower 10 in duct 14 which leads to a filter and scrubber (not shown).  A three-stage plant is also described.

Abstract: 517,175. Broaching. HERBERT, Ltd., A., and HUGO, L. J. July 21, 1938, No. 21637. [Class 83 (iii)] In a broaching-machine the tool is held in its holder by a latch coacting with an arm which may be moved aside by the latch on the return stroke to permit quick relocking of -the broach. As applied to a pull - broaching machine, two broaches 11 have taper necks 12 whereby they may be secured in bores 15 of a holder 13 secured to a slide 14. The lower ends of the broaches rest on adjustable abutment rods 16. carried by a member 18 secured to the slide. The taper portions 12 coact with bevelled surfaces 22 on a pair of spring-urged latches 20 slidable in the body 13. The springs normally urge the latches into locking position, Fig. 2, but during the upward movement after completion of an operation the latches are forced to the left by cams 25 mounted on a fixed part 26 and abut against a surface 28. In this position the partcircular portions 23 of the latches are aligned with the broaches which are thereby freed and can be lifted clear of the holder. At the start of the next down stroke the latches engage the cam tips and swing the cams aside against the pressure of springs 30. The latches can then pass beneath the surface 31 and are immediately returned by their springs to locking position.
