Patent number: 5048147Abstract: An apparatus and method are disclosed that aid an accessory of an automobile wash system in being positioned accurately with respect to a particular automobile's width. The system consists of an abutment that is positioned within the path of the conveyed automobile and which will be pivoted out of the path by contact with the automobile. The extent of the pivoting of the abutment from the path of the automobile will give an indication of the width of the automobile. A hydraulic circuit communicates this information to a hydraulic cylinder that controls the positioning of the accessory and can position the accessory to account for the width of the individual automobile. An electronic sensor system is positioned downstream of the accessory and will sense when the automobile has left the automobile wash assembly, at which time the sensor will initiate a signal that returns the members to their original position.Type: GrantFiled: October 30, 1990Date of Patent: September 17, 1991Assignee: Belanger, Inc.Inventors: James A.

Patent number: 4405158Abstract: An air-filler adapter is provided wherein an outer shell is adapted to fit various large diameter air supply hoses such as vacuum cleaner hoses, and a smaller diameter stem portion fits a variety of low pressure and medium pressure air filler openings used to inflate various inflatable consumer goods. The stem portion extends beyond the outer shell and has an outer tip which is adaptable to various air filler valves which are smaller than the vacuum cleaner hoses.The adapter comprises a pair of concentrically disposed tubes, the inner of which fits schrader air chucks on one end and fits the air filler openings for the consumer goods on the other end. The outer tube is sized to fit low-pressure pressurized air sources such as vacuum cleaner hoses and has an end wall which seals against the outside of the inner tube.Type: GrantFiled: May 26, 1981Date of Patent: September 20, 1983Inventor: Richard Huberman

Patent number: 4404728Abstract: A tool pot cleaning system for use by installing in a tool magazine of an automatic tool exchanger in machine tool. The tool pot cleaning system, installed in a tool magazine, equipped with a number of tool pots supported radically with an angle of elevation along the outer circumference of said tool magazine, comprises an air connection port disposed at the inside of the tool cradle and an air passage formed in the base of the tool pot. When the tool pot is tilted for exchanging tools, the air passage is channeled through to the said air connection port and the air jets into the tool pot to perform the cleaning of the inside of the tool pot.Type: GrantFiled: April 24, 1981Date of Patent: September 20, 1983Assignee: Mori Machinery Co., Ltd.Inventor: Kazutomi Ishikawa

Patent number: 4404706Abstract: A centrifugal air blower unit includes a casing comprising two separable sections which enclose a centrifugal impeller. The impeller has a hub including a threaded bore for attaching the impeller to the distal end of a drive shaft extending from a support of a portable power unit. The casing is adapted to mount on a support housing for the drive shaft. The hub of the impeller includes a portion extending in a direction opposite to the threaded portion and through an opening in the bottom wall of the casing whereby the impeller may be threaded onto and off of the drive shaft for connecting and disconnecting the blower unit to the bearing housing without disassembly of the casing. The casing includes a mounting pad formed integral with one of the casing parts and supported by a plurality of spaced apart radially projecting webs forming an air inlet opening and also forming combination inlet guide vanes and a trash guard for the impeller.Type: GrantFiled: October 7, 1981Date of Patent: September 20, 1983Assignee: Emerson Electric Co.Inventor: Ronald C. Loyd

Patent number: 4398551Abstract: A beach or other surface cleaning method and apparatus is disclosed, wherein low density debris, particularly oil and tar residues, are removed for subsequent separation and disposal. The apparatus employs hydraulic principles to float the debris from the surface, propel the floated debris into a scoop, and lift the floated debris into a receiving trough for subsequent separation. Water employed to provide the hydraulic actions may be recirculated for continuous reuse.Type: GrantFiled: July 30, 1981Date of Patent: August 16, 1983Assignee: Comar, Inc.Inventor: Robert M. Moorehead

Patent number: 4366368Abstract: A portable frost and snow removing appliance for use in removing ice and snow from the surfaces of vehicle windows includes an elongated housing having a pistol handgrip at one end and containing an electrically operated two-speed blower and a resistance heater arranged to produce a high speed jet of unheated air or a slower stream of heated air through a discharge nozzle shiftably mounted on the other end of the housing and movable between first and second positions. The housing includes a lateral air outlet in a side wall between the heater and nozzle. The nozzle includes as a unitary one-piece structure therewith valve members within the housing and nozzle and cooperatively associated with the housing other end and the lateral air outlet to inversely open and close the lateral outlet and housing other end in response to shifting of the nozzle to its first and second positions, respectively, to permit air to be selectively discharged from either the nozzle or lateral air outlet.Type: GrantFiled: December 6, 1979Date of Patent: December 28, 1982Inventor: William S. Stephens, III

Patent number: 4364147Abstract: Apparatus for removing dust from the flat surfaces of stationary or moving sheets, webs, plates or similar objects has a unit which converts a low-pressure laminar air stream into a pulsating air stream. The pulsating stream contacts the surface of an object simultaneously with ultrasonic radiation. The direction of flow of the pulsating air stream, which can be ionized, may be parallel with or at right angles to the direction of propagation of ultrasonic radiation.Type: GrantFiled: September 19, 1980Date of Patent: December 21, 1982Assignee: Agfa-Gevaert AGInventors: Ernst Biedermann, Heinz Rapp

Patent number: RE33050Abstract: A hand held portable blower/vacuum assembly includes a gasoline engine mounted on a blower housing that is interchangeably operable as a blower or vacuum unit and is symmetrically arranged for right or left hand use. A U-shaped carrying handle is secured to an upper housing enclosing the engine by means of a mounting structure that includes anti vibration elements. For eliminating the effect of both gyroscopic and centrifugal forces, the engine is arranged with the piston and crankshaft in horizontal and vertical orientations respectively, while both exhaust and cooling air are discharged from the front of the unit away from an operator so as to provide a balanced unit operable with either the right or left hand. A multi-position throttle located on the backside of the unit removed from the handle is incrementally settable for operating the unit at preselected fixed speeds.Type: GrantFiled: October 16, 1987Date of Patent: September 12, 1989Assignee: White Consolidated Industries, Inc.Inventors: Lloyd H.
