Patent number: 4710755Abstract: An alarm for a milk cooler which sounds when the temperature of milk within the cooler exceeds a predetermined value. A switch permits the device to be turned off to prevent it from sounding when milk is being discharged from the cooler or when the cooler is being cleaned with hot cleaning solvent. However when fresh milk is being introduced into the cooler that switch is overridden and the alarm sounds should the milk not be cooled to the required temperature after a predetermined interval of time.Type: GrantFiled: May 12, 1986Date of Patent: December 1, 1987Inventor: Robert A.

Patent number: 4705313Abstract: In a preferred embodiment of the invention, a depending pair of fingers may be caused to grip a component on an inside surface by spreading the fingers apart or to grip the outside surface of a component by closing the fingers upon the component, with the relative orientation of the gripping faces of the fingers depending upon sliding displacement of the tool posts supporting the fingers. The fingers are driven into positive engagement with the surface to be gripped, for both inside and outside gripping, via positive displacement and spreading of cam followers by a cam which, in turn, is displaced by a fluid cylinder. Alternatively, the fingers may be biased into engagement with the surface to be gripped, for both inside and outside gripping, with disengagement of the fingers being provided by positive displacement and spreading of the followers by the cam.Type: GrantFiled: June 30, 1986Date of Patent: November 10, 1987Assignee: Universal Instruments CorporationInventor: John G.
