Title: Ostomy bag
Inventor: STEER PETER LESLIE
IPC: A61F5/441
Filed: 1983-11-21
Abstract: An ostomy bag has front and rear walls joined by a peripheral weld, the rear wall having a stomal orifice and means by which the bag can be attached to a wearer, and the bag also has a compartment in its upper region, intended for the attachment of a clip-on filter. The compartment is defined by welding the bag walls together with a so- called tramline weld having one or more gaps therein and extending in an arcuate manner to join at each of its ends with the peripheral weld, the or each gap having a tapering configuration so that the gas path becomes narrower as the gas enters the compartment. This arrangement provides an improved control of gas flow passing from the main internal volume of the bag into the compartment, and avoids a problem which may occur in bag manufacture when arcuate bar welds are used to demarcate the compartment. <IMAGE>

Patent GB-2136214-A (GB)
Title: Pulse transformer
Inventor: HEMINGWAY THOMAS KEITH
IPC: H01F19/08
Filed: 1984-03-12
Abstract: The amount of insulation needed in a high-voltage pulse transformer conflicts with the requirement to provide close coupling between the transformer windings in order to ensure sufficiently fast pulse rise times. A secondary winding is made up of a coiled length of wire 3 with an insulating sheath 4 and a primary winding is formed of a plurality of parallel connected winding sections 5. The windings can be made from a length of screened cable. Alternatively, the conductor sections 5 could be provided by electroplating the sheath 4 after it has been wound into the required form. The winding could be formed on a core, for example a rod or pot core but preferably as a toroid on a ring-shaped core. The transformer may be used in a laser pump circuit in order to step up the output of a comparatively low voltage pulse generator to the high voltage required by the laser. <IMAGE>

Title: Controlling clutch slip particularly in torque converter lock up clutches
Inventor: YONEDA HARUAKI
IPC: F16D48/02
Filed: 1985-08-12
Abstract: In the control of the slip in a slip clutch device for joining and separating an input shaft and an output shaft, the improvement comprises detecting a slip in the clutch, calculating a time change in the said slip and calculating a slip deviation between a preset target slip and the said slip, and feedback-controlling the engaging force of the clutch in proportion to the quantity of the time change in the said slip, obtained from these calculations, and the slip deviation so that the slip in the clutch is caused to get near to the target slip. According to the slip clutch device control method of this invention, the hunting in slip can be prevented from being caused even when the  mu -v characteristics of a clutch facing is worsened, and a shock applied upon the clutch at the start of its operation can be reduced in a large extent.
