Abstract: This invention relates to peroxygen bleaching activator compounds and bleaching compositions. The peroxygen bleach activator compounds, used in combination with peroxygen bleach compounds which yield hydrogen peroxide in an aqueous solution, provide effective and efficient bleaching of textiles over a wide range of temperatures. In a highly preferred embodiment the bleaching compositions of the invention are detergent compositions.

Abstract: The present invention involves improvements in reciprocable pumps. In one aspect, applicable to single action pumps, a quick release mounting means is provided for attaching a fluid end piece to a power frame. The frame has a tapered opening for receiving a barrel portion of the fluid end therein. A wedge device of mateable taper with the opening connects the barrel securely to the frame. The wedge extends around the transverse outer periphery of the barrel portion. Another aspect of the invention involves providing axially rotatable intake or exhaust manifolds. In a multiplex pump, the manifold may be rotatable as a unit, or the section for each conduit may be separately rotatable. This feature permits easier handling when making repairs, especially on larger pumps. Finally, in pumps having non-vertical suction or discharge passages, the valve counterbores are tilted toward a vertical direction, but not more than an angle at which straight-line machining of the suction or discharge passage is still possible.

Abstract: A low modulus, one component, room temperature vulcanizable silicone elastomer which has very good oil resistance properties as well as high elongation. The silicone elastomer which has low volatility comprises a silanol terminated diorganosiloxane base polymer, a trimethylsilyl terminated diorganopolysiloxane, generally a tin catalyst, as well as a oxime crosslinking agent and specific low moisture fillers, usually calcium carbonate. The material is ideally suited as a gasket sealant as well as a formed-in-place gasket and can be utilized on internal combustion engines such as automotive engines as a sealant for an oil pan, valve cover, side seals and the like.

Abstract: A multi-directional vibration attenuator seat is capable of limited, restrained movement in any direction within a generally horizontal plane in response to vibration and other motions of the seat and the vehicle in which the seat is mounted. The limited movement is made possible by a seat arrangement in which an intermediate assembly is disposed on top of and slidable relative to a base assembly along a first axis with a seat supporting upper assembly being disposed on and slidable relative to the intermediate assembly along a second axis extending in a direction generally perpendicular to the direction of the first axis. The seat is normally maintained in and is restrained from movement out of a nominal position relative to the base assembly by a plurality of springs. A pair of shock absorbers disposed generally perpendicular to each other damp movement of the seat along the first and second axes respectively.

Abstract: An FM discriminator useful in a modem circuit includes a tank circuit coupled to an input receiving an FSK input signal. The FSK input signal is resistively coupled to an input of an operational amplifier having its output also coupled to that input. The other input of the operational amplifier is connected to the tank circuit and to an input of a comparator. The other input of the comparator is connected to the output of a circuit which produces a signal that lags by 90 degrees the signal produced by the tank circuit. The output of the comparator is used to synchronously chop the output signal of the first operational amplifier in such a way as to pass the operational amplifier output signal when the comparator output signal is a "1" and to invert the operational amplifier output signal when the comparator output signal is a "0".

Abstract: A seat suspension system, which includes a height adjustment valve for positioning a seat at a desired height in response to manual positioning of a height adjustment lever by controlling the amount of hydraulic fluid supplied to a cylinder having a piston therein coupled to the seat, provides damping of vertical motion of the seat by an accumulator coupled to the cylinder via a conduit so as to receive the hydraulic fluid from the cylinder and two different valves disposed in the conduit. A manually adjustable flow control valve has an adjustable orifice within the conduit for providing the seat with a nominal amount of damping.

Abstract: A process is disclosed for coloring fiber materials selected from cellulose, natural or synthetic polyamides, and mixtures thereof, which comprises applying to said fiber material a water soluble dyestuff which, in the form of the free acid, has the formula: ##STR1## wherein R.sub.3 is halogen and R.sub.4 and R.sub.5 are each independently selected from hydrogen, methyl, ethyl, methoxy and ethoxy, and fixing said dyestuff on said fiber material by the action of an alkaline agent and the optional additional application of heat or steam . The dyestuffs utilized are distinguished by outstanding fastness properties such as fastness to light, wet processing and acid.

Abstract: A vibration attenuator seat includes a seat assembly with a pair of paralleled shafts slidable in horizontally positioned, ultra low friction, linear bearings mounted in a base assembly. A seat adjustment assembly has a bottom part which is a part of the base assembly and a latch in its top part for engaging the bottom part to lock the top and bottom parts in a plurality of positions. A pin secured to the top part of the assembly centers the seat assembly relative to the top part by being connected by one preloaded, closed-coil spring to one end of the seat assembly and by a second preloaded, closed-coil spring to the other end. The body of a shock absorber positioned parallel to the shafts is secured to the pin and the rod is secured to the seat assembly.

Abstract: Apparatus for preventing injury to fielders, including control means to be actuated by a coach or other person or persons, and separate fielder units to be carried by different fielders and adapted to receive radio signals from the control means and produce signals which can be sensed by the fielder to indicate to him which of the fielders is nearer to the ball and should field it.

Abstract: A disposable pressure vessel includes a gas valve containing cylindrical cap encircled by an O-ring. The cap is bonded to an annular flared portion of a generally cylindrical rubber bladder and is disposed in a hollow cylindrical housing such that the cap compresses the flanged portion of the bladder against a shoulder in the cylindrical housing. The cap is held in place by three equally circumferentially spaced, lanced portions of the cylindrical housing and the O-ring seals the interior of the cylindrical housing from the exterior.
