An improved railroad stub switch is described in which the axial rail tension or compression forces due to temperature fluctuations are transmitted through the switch by means of radius arms connected to both the switch and fixed rails, thereby eliminating the need for expensive expansion joints at the switch. In a preferred embodiment, interlocking point shoes are also employed so as to hold the butt ends in vertical and horizontal register and transmit a signal to the trailing side rail of the...

A clipboard assembly which may be used to facilitate the writing of messages and the like on paper in the out-of-doors under all types of weather conditions. The assembly includes a writing surface in the form of a base member to which is affixed a spring biased clip for holding one or more sheets of paper in place on the writing surface of the base member. A clear plastic housing surrounds the base member, the housing having a top panel and integrally formed side and rear panels which are joine...

A Rayleigh fader for use with signals such as single-sideband and AM radio signals applies those signals to a 90-degree power divider. Each of the outputs of the power divider is taken to a separate double balanced mixer. Each separate double balanced mixer receives a mixing input from a noise source that includes a voltage-to-current converter. Mixed outputs of the two double balanced mixers are re-combined in a power combiner to produce a Rayleigh faded output.

An all purpose dental syringe and delivery system for dispensing various types of dental materials as may be required in the performance of various dental procedures e.g. the administering of anesthesia, making impressions, performing root canals, filling cavities, etc. that includes a power handle having a plunger which is incrementally advanced upon each actuation of the power handle and a plurality of interchangeable barrel assemblies. Each of the plurality of barrels assemblies includes an a...

A clear, single phase, liquid cleaning composition particularly suitable for cleaning hard surfaces which leaves a low residue on unrinsed, cleaned surfaces consisting essentially of, by weight, 2-8% of an amine salt of an anionic sulfated or sulfonated detergent containing an alkyl radical of 8 to 22 carbon atoms in the molecule, 1-4% of water-soluble, ethyleneoxylated nonionic detergent, 2-15% of an amine salt of C.sub.1 -C.sub.3 monocarboxylic acid builder, 0.1%-4% of amine, 0-2% of an amine ...

An all terrain vehicle equipped with an internal combustion engine which is connected to a torque responsive continuously variable transmission which in turn is connected to a simple automotive type differential. One output of the differential is connected to the right wheels and the other to the left wheels. The distance between the front to rear wheels, which are non-steerable, is smaller than the distance between right and left wheels to mimimize the vehicle's resistance to skid steering. Spl...

A cultivating attachment having a frame mountable on a vehicle, and a plurality of opposed pairs of cantilever mounted mandrel shafts rotatably mounted on the frame. Each shaft, which may be rotated by power from the vehicle by way of a common, frame mounted main shaft, is arranged for selectively receiving a desired arrangement of earth moving hoe blades. Rakes may be adjustably associated with the mandrel shafts, and a dusting device arranged on the frame for passing a dusting material through...

A magnetic compass of the flux valve type, capable of proper indication in ll attitudes within the earth's magnetic field. When the compass is mounted in a vehicle, it compensates for vehicle orientation and motion, and deviation or installation error may also be compensated for. The compass is provided with four compensating poles arranged 120.degree. spherically apart from each other radiating from a center. Each set of three poles of the four operates much like a conventional flux valve, but ...

A fish holder intended for use to facilitate the removal of a fishing hook from a freshly caught fish and formed of a funnel-like open ended receptacle having a longitudinal slot extending from end to end to permit a fishing line to be drawn therethrough with the fish thus being drawn through the funnel until its head portion projects through the narrow end with the tail projecting from the open end, and a clamp receiving slot disposed in the funnel adjacent the top narrow end thereof and adapte...

A motor cycle type of vehicle having three wide track wheels in line and steerable front and rear wheel assemblies adaptable to be used on a great variety of terrains and easily convertible to a snowmobile by the application of a traction belt on the rear and intermediate wheels and skis replacing the front steering wheel. The rear traction wheel has a novel suspension which permits coupling it with the front steering wheel to facilitate turning of this wide track vehicle and to prevent its trip...
