Title: Improvements in apparatus for cleaning and degreasing with solvents
IPC: D06F43/06
Filed: 1934-11-28
Abstract: 430,704. Degreasing articles by volatile solvents. DINLEY, C. F., 15040, Glastonbury Street, Detroit, Michigan, U.S.A. Nov. 28, 1934, No. 34234. [Class 91] An apparatus for degreasing metal and like articles with a volatile solvent such as benzine, benzol, carbon tetrachloride or trichlorethylene, consists of a closed container 10 having open upright entry and exit stacks 14, 15, the lower end of exit stack being provided with a pure solvent bath 20 to rinse the articles and to act as a liquid seal against egress of vapours. The articles are attached by hooks or supported on trays carried by a conveyer 12, which passes downwards through the entrance stack 14 between impinging jets or sprays of solvent supplied from a well 18 which is heated by a removable steam unit 17. The conveyer then passes around U- shaped members 40, 41, mounted in the upper part of the container-filled with solvent vapour, and finally around a member 42 mounted in the rinsing bath 20 containing warm pure solvent supplied by condenser 21. The articles then travel upwards through the exit stack 15 in a substantially dry condition. Solvent vapours carried by the cleaned articles are condensed by a cold water jacket 29. Solvent spray in the entry stack may be vented into the container 10 through an opening 23, provided with a sliding gate 25, and vapours are liquefied and returned to the well 18 by a condenser 22. The pure solvent bath 20 is provided with an apron 30 and an inverted syphon 32 by which excess solvent passes into the well 18. The used solvent is regenerated by draining the solvent from the bath 20 into the well 18 and the resulting vapours are condensed and fall into the bath 20 from which the solvent passes to a tank 73. The steam unit 17 is then removed, the well 18 is cleaned, and after replacing the unit 17, solvent is admitted from the tank 73. Solvent vapours are then generated to fill the bath 20.

Title: Centralised control mechanism for starting and operating internal combustion engines
IPC: F02N11/08
Filed: 1932-12-03
Abstract: 398,375. Controlling motor vehicles. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Dec. 3, 1932, No. 34275. Convention date, Dec. 4, 1931. [Class 79 (v).] In a control mechanism for a motor-vehicle engine, in which a driver-actuated member controls a starting motor, a clutch motor, and the throttle valve, initial actuation of the control member energizes the starting motor, further actuation allows the engagement of the clutch, and still further actuation effects opening of the throttle valve. As shown, the clutch is controlled by a lever 12 connected to a suction-actuated piston 13 in a cylinder 14 connected by a flexible conduit 15 to the engine intake manifold 3. The main control member is a pedal 25, which operates the switch 7 of the starting motor through a push link 26 having an enlargement 27 journalled in a sleeve member 28. The sleeve 28 is pivoted to a bell crank lever 31 which actuates the movable member 34 of the switch 7. A shoulder 37 on the enlargement 27 is normally engaged by a latch member 35 sliding in a cylinder 36 connected at 39 to the inlet manifold, so that the member 35 is withdrawn by engine suction during normal running and disconnects the pedal 25 from the starter switch 7. To control the clutch and the throttle valve of the carburetter 2 from the pedal 25, an adjustable abutment 41 on the link 26 engages a lever 43 pivoted at 44 on a bracket 45 and connected by a flexible cable 47 to a piston valve 23, which connects the conduit 15 alternatively to the inlet manifold 3 or to a port 19 open to the atmosphere. An arm on the spindle 51 of the carburetter throttle is actuated from the valve 23 through linkage 52, lost motion being provided at 53. To enable the throttle valve to be partly opened during cranking of the engine, an arm 73 on the throttle spindle may be connected by a link 76 to the switch lever 31. The clutch lever may be retained in. its depressed position, in order to hold the clutch open in case of engine stall, by a latch 54 pivoted on the bracket 45. A finger 57 on the latch engages beneath the lever 43, and the latch 54 is hooked to interlock with the lug 56 on the lever 12, so that operation of the lever 43 and valve 23 is prevented until the lever 12 is depressed by engine suction acting on the piston 13, or by foot pressure on the pedal 59. To allow operation of the vehicle without utilizing the clutch motor, an abutment 63 on a lever 61 is held by a spring 65 in engagement with the lever 43, but can be withdrawn bv pressure on a button 66 to render the clutch motor operative.
