A mobile modular foam fire suppression apparatus includes a movable platform. Supplies of foam concentrate and water are remote from the platform. A foam concentrate pump mounted on the platform pumps foam concentrate from a remote supply, such as a foam concentrate tank or tailer, to a water/foam proportioner on the platform. Water is provided under pressure from sources such as pumper trucks to a water inlet of the water/foam proportioner. The proportioner mixes the water and the foam concentr...

A windshield wiper blade capable of inexpensive manufacture and having good wipe quality comprises approximately 100 parts by weight of a vulcanizable elastomer including at least one silicone polymer, and about 75 to 220 parts by weight of a siliceous filler dispersed in the elastomer. The siliceous filler preferably includes a substantial portion of particles having a relatively large diameter in the range of 5 to 100 microns in order to lower the coefficient of friction of the wiper blade wit...

A rotatable gripping surface for a derailleur-type bicycle gear shifting system is formed of a resilient material with axially extending alternating ribs and grooves. The ribs and grooves are spaced such that they fit naturally into the crooks of the rider's thumb and finger or fingers and the portion of the palm therebetween. The ribs provide an increased diameter to aid in the transmission of torque and to protrude above any mud which may have collected thereon. To further enhance the torque t...

An apparatus and method for synthesizing a sinusoidal signal generated from a plurality of sample values taken at sample times in succeeding sample intervals. The signal is defined by a parameter which varies by a step value during predetermined sample intervals when the parameter changes from a first value to a second value. The apparatus includes a first logic unit for iteratively treating an initial step value to generate succeeding samples of the step value and a next step value. The next st...

Nubbed grips for hand-rotatable bicycle gear shifters have longitudinally elongated groups of nubs (50, 96, 142) that are angularly spaced apart by valley regions (44, 98, 156). Preferably, the elastomeric nubs are formed both on a cylindrical portion and an adjacent flanged portion of the grip. In an alternative embodiment, shark tooth nubs (142) offer leading faces (158) against which a hand of a rider may abut in either rotational direction for maximum torque transmission.

A combination stacking damage detector and antistacking warning device (10) is preferably affixed to the intersection of pallet tying straps (S) to the top of a pallet (P) of goods so as to provide a readily visible warning that a second pallet is not to be stacked upon the first, and also so as to provide a readily visible indication that stacking damage may have occurred. In a preferred embodiment, the device is formed of an integral blank of cardboard and is assemblable into a four-sided pyra...

A bag having three compartments, one each for a left speaker, a right speaker and a main unit, is adapted to be releasably mounted to the handlebars of a motorcycle or the like. The bag is provided with stiffening wings to better affix the stereo system to the motorcycle and to resist buffeting by the wind, and grommeted holes for internal wiring.

A painted elastomeric component capable of withstanding temperatures within at least the range of 32.degree. F. and 500.degree. F. and having good flexibility and reflectivity of heat and capable of deformation without damage to the paint. The elastomeric component has a painted surface. The coating of paint covering the painted surface includes about 100 parts by weight of a room temperature vulcanizing sealant, about 300 to 1,000 parts by weight of an aromatic or aliphatic solvent and about 20...

Apparatus (10) for providing manipulative physical therapy includes a first mass (14) of a putty including a reaction product of siloxane with a boron- or tin-containing compound and a normal polysiloxane. At least one additional mass (18-32) of the putty is provided to the patient, the additional mass adaptable to be manually combined by the patient with the first mass (14) until a uniform color is achieved in the combined mass (38). Preferably, a plurality of additional masses (18-32) having a...

A microwaveable exercise putty includes a borosiloxane or stannosiloxane reaction product. The resulting reaction product is mixed with a second polysiloxane, an internal lubricant such a monounsaturated fatty acid, and a particulate material which creates heating upon subjection to microwave energy. Precipitated silica is a particularly preferred particulate material. The exercise putty may be manipulated by patients, and at the same time is capable of delivering heat to the body part undergoin...
