Abstract: There is disclosed an insect growth regulator composition comprising (a) an insect growth-regulating active ingredient and, if necessary, another insecticidal active ingredient, (b) an organic substance having a solubility of not greater than 2% in water at 20.degree. C. and a melting point of 35.degree. through 100.degree. C., and (c) a glycol selected from the group having a melting point of 35.degree. through 100.degree. C. and consisting of polyethylene glycol, polyoxyethylene polyoxypropylene glycol, polyoxyethylene polyoxybutylene glycol, and polyoxyethylene polyoxypropylene polyoxybutylene glycol, wherein the weight of the constituent (b) is equal to or greater than 3% based on the total weight, and a sum of the weight of the constituent (b) and the weight of the constituent (c) ranges from 20 to 98% based on the total weight, the constituent (b) and the constituent (c) being molten and then cooled to be solidified in manufacturing process of the insect growth regulator composition.

Abstract: It is an objective of the present invention to provide a scintillation counter that can measure the intensity of only .beta. rays. Two scintillation fibers (11 and 12) which emit different wavelengths are provided in series to a probe (10). One of the scintillation fibers (12) is covered with a .beta.-ray shield. The optical signal generated at the probe (10) is transmitted through the optical fiber (20) and separated by the light separating element (31). One portion of the separated optical signal is incident on a light detector (32) and the intensity of the incident light detected. The other portion of the separated optical signal is incident on a light detector (33) and the intensity of the incident light detected.

Abstract: A four-way closet spud insertion tool for inserting a spud into a inlet/outlet hole of a plumbing fixture. The closet spud includes a couple having at least one lug protruding inwardly therefrom and a gasket circumscribing the couple, the gasket having a flared portion that is to be inserted into the inlet/outlet hole of the fixture with a portion of the couple, the diameter of the flared portion being greater than the diameter of the hole. The spud insertion tool comprises a cross-shaped body having four arms extending from a center point thereof, each of the arms terminating in a different head, each of the heads being configured to be insertable into a respectively sized couple, the force being sufficient to compress the flared portion of the gasket such that the flared portion can pass through the hole of the fixture.

Abstract: A solar-energy collector has an absorber (5, 31) located in the bottom of a box-like casing, which includes a cover plate (1) which is permeable to solar radiation. The casing encloses a dry gas, to thereby avoid condensation in the solar-energy collector. The casing is hermetically sealed and contains a constant quantity of gas. The cover plate is movably suspended in a resilient frame (2, 20) which forms part of the casing and which permits movement of the cover plate in a direction perpendicular to the plane thereof in response to changes in gas temperature. This enables harmful pressure variations to be avoided in the collector, and the cover plate rests, well protected, on an elastically resilient cushion of gas.
