Title: Compositions for the treatment of textile materials and the application thereof
Inventor: JELLINEK THOMAS
IPC: D06M13/325
Filed: 1979-05-02
Abstract: Compositions for textile treatment comprising an admixture of:
     a) an aqueous emulsion based on a copolymer of a monomeric mixture containing 0.5 to 50 %, preferably 2 to 40 % and most preferably 4 to 30 % by weight of an oxirane-containing monoethylenically unsaturated material. and at least one other monoethylenically unsaturated material and   b) a water soluble or water dispersible polyamine which is comprised of at least one segment of formula A. consisting of repeating alkylenimine units (-CH-CH-N-):
     wherein R 1  and R 2  are independently selected from hydrogen and lower alkyl radicals of 1 to 4 carbon atoms, R 3  is H or other polyalkylene polyamine segments of formula A, and n is a number having an average value of at least 2 when R 3  is H, and is taken to be the sum of all alkylenimine units when R 3  is other than H.   
     The compositions may be used at low application levels so that wool-containing textiles in particular may be rendered shrink-resistant without impairment to their handle, colour, strength or to other desirable properties of the fibre.

Abstract: In a dental apparatus, in which a number of instruments (19 to 22) are connected to a common control circuit (23) which is further connected with a common operator unit (17) having a control member, which is planar movable out of a home position, auxiliary functions related to the instrument operation such as control of coolant composition and energization of an air blow may be energized by the means of the common operator unit (17) by actuating the control member thereof with a movement different from the instrument energizing movement. The energizing movement for an auxiliary function may have another direction than the instrument energizing movement, for example perpendicular thereto in the home position of the control member. In an embodiment in which a certain minimum duration is prescribed for the instrument energizing movement an auxiliary function may be carried out by a movement of shorter duration. The two possibilites may be combined so that also in case of a different direction related to the instrument energizing movement a discrimination may be made between actuation of auxiliary functions of a shorter or longer duration for the purpose for example of stepwise control of an auxiliary function.

Abstract: A fluid pressure braking system for an articulated vehicle having a towed unit and a towing unit includes a source of fluid pressure carried on the towing unit and a supply line (58) and a service line (62) which communicate the braking system on the towing unit with the braking system on the towed unit. A first proportioning valve (76) controls communication to the relay valve (84) which controls communication of braking pressure to the rear wheel service brakes on the towing unit. The proportioning valve (76) is controlled by an inversion valve (90) which is responsive to the pressure leval in the supply line (58). When the pressure level in the supply line (58) is below a predetermined level indicating that the towing unit has been disconnected from the towed unit, the inversion valve (90) causes the proportioning valve (76) to proportion communication to the relay valve (84). A second proportioning valve (28) controls communication to the front wheel brakes of the towing unit and is responsive to the signal from the inversion valve (90) to proportion communication to the front wheel brakes when the towing unit is connected to the towed unit but which permits an uninhibited communication to the front wheel brakes when the towed unit is disconnected from the towing unit. A third proportioning valve (34) controls communication through the service line (62) and is responsive to an operator actuated control valve (68) to provide proportioned brake applications on the trailer service brakes when the trailer is lightly loaded. A synchronizing valve (40) is responsive to the magnitude of the brake application to reset the operator actuator valve (68) when higher pressures are generated, indicating that the towed and towing units have been recoupled.
