Title: Sewing machine control - use resistances of different electrical values at sewing machines and/or motors to give selective specification for a control action
Inventor: HOSAKA TOSHIHARU
IPC: D05B69/18
Filed: 1991-10-23
Abstract: The control system gives a choice of a number of controls for the various sewing machine units where each of them has a resistance with different electrical resistance values. Meters can be linked to the resistances to measure the current flow through them to specify the sewing machine unit which is to be connected to the control system. The selection of the unit to be controlled uses the measured current flow to specify the function. The meter to register the current flow through the separate sewing machine units can also register the voltage to specify which function is to be controlled for the selection system to use the measured voltage. Multiple resistnaces can be fitted to the sewing machine units to be controlled, or single resistances are used. The controlled sewing machine units are a number of sewing machines units. or a number of sewing machines and motors. ADVANTAGE - The control system for the sewing machine and/or a motor requires a single input to register the operation to be controlled through the measured resistances.

Title: Filtering solid particles from liquids e.g. metal working lubricants - by tilting bath contg. fluid bearing metal chippings, when specified depth is reach allowing filter panel to be advanced and substd. by new section from same roll
Inventor: JOPPIEN MANFRED FRITZ
IPC: B01D29/09
Filed: 1991-10-23
Abstract: The removal of solid metal particles from a liquid fluid bearing a load of metal chippings is drained to a bath at the base of which is a filter panel thorugh which the fluid drains for collection. As the chippings collected increase, the filter is blocked and obstructs the further passage of fluid which accumulates. When the depth of accummulating fluid in the bath reaches a predetermined depth, the bath is tilted to move the fluid from the filter surface and relieve the downward pressure allowing the filter panel to be advanced and substd. by a new section from the same roll. Filter assembly pref. consists of an outer tank (10) within which a drum (11) consists of a perforated curved base (14) supports a fitler fleece held between curved sidewalls (13). Assembly is pref. supported by an axle (12). Curved base perforations are pref. covered by a filter fleece (16) taken from a roll (15). Float switch (24) pref. detects rising fluid to activate the tipping mechanism and advance the roll when fluid pressure on the blocked section is removed. USE/ADVANTAGE - Easy means by which fleece filters mats can be exchanged when blocked without tearing the mats. For the receovery of fluids used to lubricate and cool metal working processes.
