Title: Interrupted DC supply
IPC: H02H7/22
Filed: 1978-09-27
Abstract: An electrical appliance having a power supply switch suitable for A.C. operation only is operated from a DC source by applying constant voltage pulses to the appliance. The spaces between the pulses are long enough to extinguish any arc that forms across the switch contacts when they are open. A D.C. to D.C. converter includes transistors 8,9 and saturable transformer 6 controlled by a circuit 16 including an oscillator 23. During the high level output of the oscillator 23 no current flows in an auxiliary winding 26 and the operation of the converter is not hampered. When the oscillator produces its low level output the core of transformer 6 saturates and the output of the converter falls to zero to interrupt the D.C. output supplied to the appliance 3. <IMAGE>

Title: Automatic checking of batteries or cells
IPC: G01R31/36
Filed: 1979-04-12
Abstract: The drawing illustrates one form of apparatus for continuous monitoring of the internal resistance of a battery or cell. Periodically, a capacitor 16, after charging to a higher voltage than the battery or cell 10, is discharged by thyristor 23 through the battery or cell 10 and a resistor 22.

Title: Process for shredding tobacco stems
IPC: A24B5/16
Filed: 1979-04-12
Abstract: The processing of tobacco stems in cigarette making has been complicated in the past because of the structural dissimilarity of the rod-like stems in comparison with the laminar portions of the tobacco leaf. This invention provides a solution to this problem by a process for shredding tobacco stems so they are structurally compatible with the laminar portions of the tobacco leaf. The process comprises the shredding of tobacco stems by splitting or parting the stems along the grain to produce light, pliable, low bulk density fibrillar shreds. Stems shredded according to the present process exhibit sufficient resiliency so that when massed they approximate or exceed the filling capacity of cut leaf shreds. Apparatus utilizing blunt rotatable blade-like elements (20 or 34) are also disclosed.

Title: Spin dryer
IPC: D06F49/00
Filed: 1981-08-03
Abstract: When lid 5 is closed it pushes down lever 18 with its movable cam 23, so that spring-loaded member 17 is released by claw 30, and moves into the uppermost lid catch 20 to secure the lid. Tightening of cable 9 by the lever 18 pulls a braking shoe 13 from a disc 11 under motor 1, and operation of a switch 19 by a carrying lever 14 for the braking shoe actuates a switch to cause the motor to spin drum 2. When the motor 1 is switched off the shoe is pushed into contact with the disc, where it remains through rotation of two-armed lever 16 on the carrying lever, in consequence of friction between the disc and shoe, until the disc and drum have come to a stop. Meanwhile, the rotation of the lever 16 prevents spring 10 from pulling on the cable 9, and so releasing the lid 5, until the drum has stopped turning. <IMAGE>
