Title: Method and apparatus for changing lubricating oil
IPC: F01M11/04
Filed: 1972-12-08
Abstract: 1409575 Changing engine sump oil AEROQUIP AG 8 Dec 1972 [15 March 1972] 56842/72 Heading A4T For changing oil in engine sump 12, Fig. 1, a conversion kit in the form of a hose 17 has one end permanently connected at 15 to the sump drain 13  and a self-sealing half-connector 18 at the other end fixedly secured by e.g., bracket 25 above the sump oil level preferably adjacent dip-stick 24, old oil being extracted and new oil dispensed via hose 17 by unit 26 having suction pump 35, Fig. 3 and dispensing pump 36 both driven from petrol engine 37 via a centrifugal clutch or by separate electric motors. Half-connector 51 on suction hose 31 is connected to connector 18 and engine 37 started from control panel 47 to drive both pumps 35, 36 through clutch 50 controlled by a time relay for releasing it. Dispensing pump 36 extracts new oil from a container at the back of unit 26 and recirculates it via pipe 43 and a by-pass valve back to the container, but maintains oil pressure up to the closed dispensing nozzle connector 55 of the new oil dispensing hose 29. Suction pump 35 passes old oil to container 38 via a flow switch which controls clutch 50 when the time relay control is finished and when all old oil has been extracted, which may be indicated by a Venturi-controlled piston operating an indicating button adjacent connector 51, the flow switch releases clutch 50 which is indicated at the control panel. When suction hose 31 is disconnected and dispensing hose 29 connected to hose 17 at 18, and meter 54 set to dispense the requisite amount of new oil, the dispensing pump by-pass valve is shifted and new oil is pumped into the sump, the nozzle connector 55 being closed by meter 54 when the requisite amount has been dispensed. When each pump is driven by an electric motor the apparatus is similarly controlled as before except the by-pass valve is dispensed with, and the new oil dispensing pump motor is controlled by a pressure switch responsive to pressure in the dispensing hose on opening or closing the dispensing nozzle. In further embodiments, the pumps are separately mounted on wheeled old or new oil containers, the old oil container having a level indicator and being emptied by reversing the evacuation pump connections.

A process for the continuous liquid-phase oxidation of a cyclo-aliphatic hydrocarbon, to a cycloalkanol and cycloalkanone, with a gas containing molecular oxygen in the presence of excess of a boron compound insoluble in the reaction medium e.g. metaboric acid tetraboric acid or boric anhydride comprises subjecting the crude oxidation mass containing the unreacted cycloaliphatic hydrocarbon, the oxidation products and excess boron compound to a decantation step, as defined below, so that excess boron compound is recycled with the unreacted hydrocarbon and the products can be drawn off substantially free of excess boron compound. The process is suitable for the oxidation of cyclobutane, cyclopentane, cyclooctane, cyclododecane, methyl cyclopentane and methyl cyclohexane; that of cyclohexane being exemplified. The term "decantation process" is defined as a clarification by thickening, where the term "clarification" refers to the removal of suspended solids or emulsified droplets from a liquid phase and the term "thickening" refers to the concentration of suspended solids or emulsified droplets in a liquid phase.

Abstract: 651,799. Separating solid materials by pneumatic means; feeding grinding mills. MIRACLE MILLS, Ltd. Jan. 20, 1949, No. 1775/48. [Classes 59 and 117] Flocculent or like material is fed to a pulverizing or other machine by a forced flow of air through a duct having an inlet positioned in predetermined spaced relationship to a conveyer or platform which carries the material to be fed, the required material being thereby sucked into the inlet while the unsuitable heavy material will be left behind and an alternative suction duct is provided connecting the pulverizing or like machine or a hood therefor with the means for producing the forced air flow so that when the normal air and material into the air duct is mainmomentarily partially choked the intake of air and material into the air duct is maintained substantially constant by the alternative duct. As shown the air duct of an air impeller 2 is incorporated into a pulverizing machine 1 and comprises a suction trunk 5 the inlet end of which is directed over the conveyer 6 and is flared at its end to increase the size of the inlet, the outlet being led into a closed hood 4 of the pulverizer. Impeller 2 sucks from the bottom of the pulverizer through a duct 3 including a removable screen which traps any material tending to pass with the air stream discharging through the duct 2a the material trapped causing a partial temporary choking of the air duct. An alternative suction duct 15, 14, 19 connects the hood 4 with the air impeller 2 so as to byepass the normal air duct. A screen 16 screens this alternative duct from the hood 4 to prevent flocculent material entering it and a valve 17 keeps this duct closed until suction in the hood 4 falls below that in the duct. The upper or lower sides of the trunk 5 may be adjustable between the vertical sides so as to vary the sectional area of the trunk thence the velocity of the air current to suit the material to be sucked up. A hinged plate 10 biassed by weight 12 into engagement with the end of the conveyer 6 is deflected by rejected material as it falls over the end of the conveyer.
