Patent number: 4502251Abstract: My invention is particularly adapted to saws for cutting metal, and especially abrasive disc saws, wherein the saw is fixed to a shaft which is rotatable within a bearing located at one end of a rocker arm. A drive motor, preferably an electric motor, is mounted on the other end of the arm and the latter is pivoted intermediate the saw and the motor on a bracket extending upwardly from a base. The arm swings about the pivot to move the saw toward and away from the work to be cut, which work is clamped within a vise secured to the upper surface of the base. The improvement herein disclosed comprises a manually settable timing system for adjusting the amount the saw moves in a direction away from the work, after the cut has been made, so that upward movement of the saw is limited to a position wherein the saw is only a very slight distance above the uppermost surface of the work.Type: GrantFiled: February 28, 1984Date of Patent: March 5, 1985Assignee: Charles T.

Patent number: 4502252Abstract: In a lapping apparatus, washing water is ejected from washing water holes toward a carrier holding wafers after the wafers are polished. Thus, the wafers are separated from the carrier and upper and lower polishing members. Then, the carrier is forced up above the upper polishing member by a pushing ring. The wafers left on the upper member are carried onto a table by a first sweeper of an automatic collecting device. The transferred wafers are arranged in a line along a second sweeper. Then, the second sweeper pushes and moves the wafers in the direction of their arrangement toward a cassette on one side of the table. The wafers are housed in holder portions in the cassette, and are then immersed, along with the cassette, in a pure water tank.Type: GrantFiled: March 28, 1983Date of Patent: March 5, 1985Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventor: Masaburo Iwabuchi

Patent number: 4502275Abstract: A compressor air bleed override control system is provided to bleed interstage air from the compressor of an aircraft turbine engine under the conditions during which a compressor instability, such as surge, is likely to occur. The override system includes an override valve control that is in communication with an altitude sensor to make the system operative above a preselected pressure altitude, but inoperative below the selected pressure altitude. The altitude sensor is in communication with the engine fuel control power lever, which is an indirect sensor of compressor speed, such that at speeds corresponding to a slow deceleration from a sufficiently high altitude, the compressor bleed value will rapidly open. The system further measures the rate of movement of the power lever so that small but sufficiently rapid movements of the power lever, which are sustained for a selected period of time, will also cause the compressor bleed valve to open quickly.Type: GrantFiled: October 13, 1983Date of Patent: March 5, 1985Assignee: Avco CorporationInventor: David J.

Patent number: 4502278Abstract: An exhaust cleaner and multi-point burner system for a diesel engine has a burner device with concentric first and second sets of circumferentially spaced apart point igniters facing the inlet end face of a particulate filter to effect multiple points of ignition of the particulates collected thereon, and a central point igniter to serve as a pilot light, supplied with an air/fuel mixture by a first supply conduit and a solenoid valve controlled supply conduit, respectively. The arrangement is such that the air/fuel mixture to the sets of point igniters is ignited using a single central electric igniter, such as a spark plug to ignite the air/fuel mixture supplied to the central igniter. Once all points are ignited, the solenoid valve is closed, thus increasing the flow of the air/fuel mixture to the sets of point igniters. This change in flow reduces heat losses and minimizes air/fuel requirements to effect ignition of the particulates.Type: GrantFiled: November 25, 1983Date of Patent: March 5, 1985Assignee: General Motors CorporationInventor: Terrence L. Stark

Patent number: 4502293Abstract: A generally rectangular container is provided including insulated top, bottom, opposite side and opposite end walls. An upstanding transverse insulated hollow housing is mounted within the container adjacent one end thereof and a CO.sub.2 snow cabinet constructed of good heat transfer material is disposed within the housing with opposing wall portions of the cabinet and housing passing exteriorly about the cabinet. A heat insulative horizontal baffle is mounted within the container spaced below the top wall and extends between the sidewalls thereof. The baffle defines a cooled air passage beneath the top wall extending lengthwise of the container. The airflow passage includes an outlet end adjacent and in at least reasonably closed communication with the end of the cooled air passage adjacent the aforementioned one container end wall and an inlet end opening outwardly of the housing into the interior of the container below the baffle.Type: GrantFiled: March 13, 1984Date of Patent: March 5, 1985Inventor: Paul R. Franklin, Jr.

Patent number: 4502295Abstract: An organ hypothermic storage unit includes a first container with a removable cover and a plurality of organ receptacles mounted within the first container, each receptacle having a removable cover. A plurality of groups of spacers upon the container bottom wall receive and locate the receptacles spacing them from each other and from the container walls to define a chilling zone within the first container and around each receptacle. Each receptacle mounts upon its interior a thermometer. An outer container having a removable cover receives, supports and encloses the first container defining an insulating air space therebetween. The inner container is adapted to receive and store a quantity of ice within the chilling zone for continuously maintaining an organ in any receptacle at a temperature between 0.degree. and 7.degree. C., for maximal metabolic suppression and preservation thereof until transplant to a recipient. The containers, receptacles and covers thereof are of a clear transparent material.Type: GrantFiled: February 21, 1984Date of Patent: March 5, 1985Assignee: Mount Carmel Research and Education CorporationInventor: Luis H. Toledo-Pereyra
