Abstract: A brake shoe mounting assembly is provided for a brake mechanism mounted within an axle housing located on the inboard side of a wheel mechanism and having an arcuate brake drum assembly mounted therein. The mounting assembly includes an arcuate brake shoe disposed in the housing for confronting the brake drum assembly and an actuator apparatus mounted in the housing and being engageable with the brake shoe and responsive to engagement of the brake pedal for expanding the brake shoe into frictional engagement with the brake drum. The actuator and the brake shoe are interconnected for sliding and in particular, a slotted beam assembly is attached to either one of the actuator and the brake shoe and an insertion assembly is attached to the other. The slotted assembly extends in an inboard direction and slidably receives the insertion assembly.
Abstract: Oral drug delivery systems are provided formed of compositions which include one or more hydrocolloids solids, such as gelatin, pectin, and sodium carboxymethyl cellulose, and preferably mixtures thereof, which solids contain less than about 5% by weight moisture and preferably comprise less than about 50% by weight of the total formulation; and an ointment base such as mineral oil containing dispersed polyethylene (Plastibase). Such oral drug delivery compositions may be used to deliver to the oral mucosa active ingredients such as steroids, anti-fungal agents, anti-bacterial agents and the like and do not harden even upon prolonged storage or upon filling into containers.

Abstract: A baby bottle having a generally toroidal hollow chamber. The bottle preferably has a nipple which is positioned at an angle with respect to the toroidal chamber so that the bottle can rest in a highly stable manner on its side. Preferably, the bottle also has a bisecting tubular chamber which increases the capacity of the bottle while reducing the external size thereof. One or more liquid crystal temperature sensing dots may be molded in the side of the bottle to facilitate the determination of overheated contents. A flexible handled brush can be used to completely clean all inner surfaces of the bottle.
Abstract: A steroid lotion formulation which has enhanced physical and chemical stability is formed of (11.beta.,17.alpha.)-17-(ethylthio)-9.alpha.-fluoro-11.beta.-hydroxy-17-(m ethylthio)androsta-1,4-diene-3-one (tipredane), and a vehicle containing as major ingredients polyethylene glycol, propylene glycol and water together with a potassium citrate buffer or tromethamine buffer, and sodium metabisulfite and butylated hydroxytoluene as antioxidants.

Abstract: A radar apparatus transmits right circular polarized signals and selects the right circular polarized components of the corresponding returns. It also transmits left circular polarized signals and selects the left circular polarized components of the corresponding returns. The selected left and right circular polarized compoments are processed by, for example, averaging them, producing a weighted average of them, or selecting the component of larger value.
Abstract: A steroid ointment formulation which has enhanced physical and chemical stability is formed of 11.beta.,17.alpha.)-17-(ethylthio)-9.alpha.-fluoro-11.beta.-hydroxy-17-(me thylthio)androsta-1,4-dien-3-one (tipredane), and a vehicle containing as major ingredients propylene glycol and water, cetearyl alcohol and ceteareth 20 or other dispersing agent for propylene glycol, together with a sodium or potassium citrate and magnesium hydroxide buffer to impart a neutral or slightly alkaline apparent pH (5 to 9), a non-acidic long chain fatty acid wax to impart proper consistency to the ointment and sodium metabisulfite and butylated hydroxy toluene as antioxidants, together with thickeners, emollients, lubricants and other conventional ointment formulation ingredients.

Abstract: A thermoplastic molded product useful in vehicle linings such as door trim, shelf covering and package trays is formed from a resin into a thin plate. The product is formed from a substantially uniform admixture of from about 50 to 60 weight percent of a polypropylene, from 30 to 35 weight percent of a wood flour, from 2 to 3 weight percent of a leather powder, from 2 to 3 weight percent of a defatted rice bran powder, from 2 to 3 weight percent of an asbestos fiber, from 2 to 2.5 weight percent of a waste cotton, from 1.7 to 2.3 weight percent of a chopped glass fiber, and from 0.8 to 1.2 weight percent of a calcined diatomaceous earth.
Abstract: A constant force perpendicular to the fiber axis is applied to the fiber so as to cause a power coupling from the fundamental mode, which is guided, to a secondary mode which is irradiated, and the intensity of the scattered radiation associated with that secondary mode is measured. Such intensity depends on the local state of polarization. By dispacing the force application point step by step along the fiber axis and by measuring for each point the intensity of the scattered radiation, beat length is obtained as the distance between two consecutive points where the scattered radiation has the same intensity.
