Abstract: A test method is disclosed that can be used to test cleaning products. The test method includes applying a known amount of test material to a surface, cleaning the surface and calculating the amount of allergens picked-up from the surface. The calculated amount of allergens picked-up is then corrected for several measurable variables to provide a more accurate determination of the percentage of allergens picked up with the cleaning product.

Abstract: An improved exercise apparatus, having two rails in parallel relation supported on a frame. Supported by each rail are two travellers, the four travellers for engagement with the limbs of the user. Each pair of travellers is supported by the rail one above the other, with the bottom travellers extending laterally below the rails of the apparatus. The travellers ride within grooves in the rails. An endless chain is suspended between the rails. When the travellers are coupled to the endless chain, the user encounters a resistive force from a force resistance system. Each set of travellers is selectively coupled to the endless chain.

Abstract: A theatrical imaging system for forming images where there are no image forming surfaces includes a theater having a raked audience viewing are in spaced apart relationship in front a stage. A false ceiling separates a motion picture projector and rear view projection screen, from the audience viewing area. The screen disposed above and in front of the audience provides a real image forming surface. A semi transmissive reflecting member disposed at an angle of 131/2 to 31 degrees to a vertical plane disposed normal to the average sight line of the audience member is disposed in facing relationship to the screen to generate a virtual image on the stage in the line of sight of the audience.

Abstract: A three dimensional image generating system has a multiple adjacent image generating projector aimed at corresponding juxtaposed reflectors, one of which being substantially reflective and the other of which being partially transmissive and partially reflective. A third partially transmissive reflecting member is interposed between the juxtaposed reflectors and a viewing audience. A prop supporting rotatable stage is disposed before the audience and beyond the the third reflecting member. The third reflecting member transmits and reflects to the audience a composite image composed of the three dimensional image generated by the juxtaposed reflectors and the prop image passed through the third reflecting member.

Abstract: A dispensing head having a plurality of prong-like nozzles is useful for impregnating meat with tenderizing and flavoring liquids. It may be fitted onto a pressure dispenser of the conventional type containing a bag to hold the liquid, a gas pressure space thereabout, and a reciprocable dispensing valve. The head so utilized has an inlet leading to a flushable chamber communicating to several prong-liked nozzles which project on parallel axes from a meat pressing surface, preferably having a rim. Pressing this surface so spreads the meat against the sides of the nozzles as to seal them against the escape of liquid dispensed under superatmospheric pressure, thus forcing it to impregnate the meat. The dispensing head is readily flushed; and provisions are made for re-mounting on the valve stem without discharging the contents of the container.

Abstract: A dispenser head having a plurality of prong-like nozzles is useful for impregnating meat with tenderizing and flavoring liquids, and similar purposes. It may be fitted to a conventional pressurized dispenser of the type having a tubular stem. Preferably constructed in two parts, the lower or manifold part has a bottom inlet; the upper or outlet part has a number of prong-like nozzles on parallel axes; and interfitting portions provide sealed passages to distribute the dispensed liquid to the nozzles.
