Title: Improvements relating to ventilators
Inventor: BURTENSHAW RAYMOND ALFRED FRAN
IPC: F24F7/02
Filed: 1981-10-16
Granted: 1984-07-19
Abstract: A powered, direct discharge ventilator comprises a base (B) having an extraction fan duct defined by a cylindrical wall portion (11) enclosing a fan impeller (not shown) of a fan (K) mounted on the base. A shallow windshield (D) shelters a non-return shutter (S) which closes the extraction fan duct when the fan is not operating. The shutter (S) is hinged on a pair of arms (H) to float up on the discharging airstream to take up the position shown chain-dotted in Fig. 1 when the fan is operated. When the fan is stopped, the shutter (S) closes gravitationally. To assist in holding the shutter (S) closed under high wind conditions, a wind deflector (W), carried by a bird-guard (G), directs the wind in a downwardly directed stream onto the top of the shutter (S). Where a much higher windshield is used, the wind deflector acts in a similar manner to prevent any reduction of pressure within the windshield due to the <<wind-over effect>> lifting the non-return shutter.

Abstract: Derivatives of C-076 compounds are described in which the C-076 molecule, a series of macrolides, has the 23-hydroxy group thereof oxidized to the 23-keto group. The 23-keto compounds are prepared by selectively oxidizing the suitably protected 23-hydroxy compound using such oxidizing agents as pyridinium dichromate, chromic acid-dimethyl pyrazole, chromic acid, chromic acid-acetic acid, and the like. Alternatively, selective oxidation of the unprotected 23-hydroxy compound may be accomplished by placing the compound in soil. Further reaction of the oxidized C-076 compounds is also possible. The compounds thus produced have profound anthelmintic, insecticidal, ectoparasiticidal, and acaricidal activity. Compositions containing the described C-076 derivatives as the active ingredient thereof are also disclosed.

Patent DE-3175746-D1 (DE)
Title: Hot sprue assembly for an injection molding machine
Inventor: MORRISON ROCKY V
IPC: B29C45/26
Filed: 1981-10-27
Granted: 1987-02-05
Abstract: A hot sprue assembly is provided for controlling flow of molten material into the mold cavity of an injection molding machine. The hot sprue assembly is particularly designed for use with an injection molding machine for molding centrally apertured record discs, such as video information discs. The hot sprue assembly includes a hot sprue bushing cooperating with a dispersion head to define an open and relatively narrow annular gate through which molten material is injected into the mold cavity, and a central die plug within the mold cavity for cooperating with the dispersion head to mold a central aperture into the disc. Valving of the molten material through the gate is achieved by heating the sprue assembly to create a temperature differential which, during soldification of the material within the mold cavity, permits the material within the mold cavity to soldify up to the gate without substantial soldification of material within the sprue assembly. The gate is disposed at a plane recessed slightly from the general plane of the soldified disc to prevent any surface discontinuities arising by retraction of the sprue assembly when the mold cavity is opened from projecting above the general plane of the disc.

Abstract: A zinc-bromine battery includes cathode and anode reaction tanks separated from each other by a separator membrane for preventing self-discharge, and an elctrolyte storage tank for storing an electrolyte with a bromine complexing agent added thereto. Catholyte and anolyte are circulated between the cathode reaction tank and the anode reaction tank, respectively, and the electrolyte storage tank. A perforated membrane which allows an elctrolyte permeate through it but which impedes the permeation of a bromine complex compound is provided within the electrolyte storage tank so as to separate the tank into an electrolyte mixing chamber into which both catholyte and anolyte flow and an electrolyte supply chamber which resupplies the mixed electrode as the catholyte and the anolyte. When the catholyte and anolyte are mixed with each other in the electrolyte storage tank, the zinc ion concentration is equalized as between the catholyte and anolyte, so that the zinc ions contained in the electrolyte are effectively utilized during charge, thereby improving the charging capacity and efficiency.
