IPC: F02B9/00
Filed: 1930-07-02
Abstract: 347,541. Oil engines. BAGNULO, A., 23, Rue St. Lazare, Paris. July 2, 1930, No. 20068. Convention date, July 27, 1929. Addition to 300,658, [Class 7 (iii), Internalcombustion engines, Carburetting-apparatus &c. for]. [Class 7 (iii).] In a modified form of the engine described in the parent Specification, a spherical vaporizing and pre-combustion chamber or bulb B communicates with the cylinder through a form of Venturi passage V in the walls of which are openings T, T<1> communicating with the space surrounding the portions of the passage extending into the vaporizing chamber and the cylinder, respectively. During the compression stroke, fuel which has collected in the lower part C of the bulb enters the air stream through the inclined openings T and produces a preliminary combustion which heats a metallic protuberance A and maintains it at ignition temperature. Following the combustion in the bulb B, the contents thereof are projected through the passage V into the cylinder, some of the air in the cylinder being aspirated through openings T<1> as the gases pass through the lower portion of the passage. Fuel admitted during the suction stroke through a valve G flows over the walls of the bulb B to the lower portion C, or it may be admitted directly to that portion by a small injector mounted at the side of the lower part of the bulb.

Title: Improvements in or relating to a method of and apparatus for refining magnesium
IPC: C22B26/22
Filed: 1934-07-11
Abstract: 445,849. Distilling magnesium. MAGNESIUM PRODUCTS, Inc., 100, West 10th Street, Wilmington, Delaware, U.S.A. July 11, 1934, No. 20342. Convention date, July 11, 1933. [Class 82 (i)] In the refining of magnesium by vaporizing at a temperature below the normal boiling point and condensing the magnesium vapours formed, the condensation is effected at atmospheric pressure or a pressure higher than atmospheric pressure up to about 20 atmospheres. In one form of the invention, the pressure in the condenser is greater than the pressure at which vaporization takes place, e.g. the vaporization being carried out at a high vacuum and the condensation at or above atmospheric pressure. The vaporization may be promoted by circulating indifferent gases, preferably cyclically, through the system and the condenser may be heated to obtain the metal in liquid form. In another form, the pressure in the vaporizing zone is substantially equal to that in the condenser, while using indifferent gases, and in a third form a greater pressure is maintained in the vaporizing zone than in the condenser, while using indifferent gases, the pressure in the condenser being preferably at atmospheric pressure. In both these forms, the indifferent gas is circulated cyclically throughout the system and may be preheated before being introduced into the vaporizing zone. In carrying out the first form of the invention, a furnace 1 is connected to a vacuum pump 2 which removes the vapours generated in the furnace 1 and forces them into a condenser 3 in which any desired pressure is produced by a regulator 4. When the system is being operated with an indifferent gas, the latter is admitted to the furnace by means not shown and is circulated by a pump 5 through a preheater 6 and a pressure regulting valve 7 through the furnace 1. To carry out the second and third forms, the pump 2 is replaced by a valve by which the pressure in the furnace 1 may be maintained at a pressure below atmospheric or a pressure equal to or greater than the pressure in the condenser 3. The valve 7 is omitted and the indifferent gas is circulated through the furnace by a pump placed between the preheater 6 and the furnace. Specifications 362,835 and 406,958 are referred to.

Abstract: 664,878. Control of motors. DONNELLY, I. A. F. Nov. 28, 1949. [Aug. 9, 1949] No. 20729/49. Class 38 (iii). [Also in Group XXXII] A motor vehicle hood raising linkage is operated by an electric motor 22 through a cross shaft 8 and crank 9, the motor being run only when the lid of a hood storage space is not being opened or closed by a separate lid operating motor 23. The motors are supplied from a battery 24 and operated by push button switches 21a, 21b, on the vehicle dashboard, and through limit switches 26-29 and relays 25a, 25b, Fig. 2. Assuming that the hood is up and the button switch 21b is made, then a circuit is established from the battery 24, through the limit switches 27, 29, the field 23u and armature 23a to earth and return accordingly rotates to open the lid, which when fully opened changes over the switch 29 and connects the battery through contact 29b and the still closed switch 21b to earth through the relay 25b. This relay establishes connection through the field coil 22d to cause the motor 22 to lower the hood. When the hood is fully lowered the motor 22 changes over the limit switch 27, breaking its own circuit and establishing a circuit through the switch 21b, switch 27, switch 28 (closed by the lid motor at the end of its movement), through the field coil 23d to earth. The lid motor therefore rotates to close the lid and open the switch 28. A similar circuit arrangement is operated through the switch 21a for the "hood up" operation.
