Filed: 1929-04-03
Abstract: 309,079. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). April 4, 1928, [Convention date]. Condensers of the plate or wound type are, after impregnation with paraffin, oil, or the like, cooled, either in the impregnating vessel or in a cooling vessel to which they are removed, by means of a medium, such as nitrogen, or other gas', which is led in a closed cycle and cooled from outside, as by a refrigerator where the cooling medium does not come into contact with the freezing medium. Alternatively, cooling medium can be led through pipes arranged in the impregnating vessel itself, and such pipes can be arranged also to convey the heating medium for the impregnation process. The process ensures that no dust or moisture shall enter the cooling condenser from the surrounding medium.

Inventor: KORTE ALFRED CONRAD
IPC: F01M1/24
Filed: 1952-04-25
Abstract: 711,749. Engine stop-gear. CARTER CARBURETOR CORPORATION. April 25, 1952, No. 10513/52. Class 122(4) [Also in Group XXVII] A protective control system for a pressure lubricated internal combustion engine comprises an electrically driven fuel pump 10, an electrical system including a starter motor 22 and. switch 28 therefor and a battery 23 connected through an ignition switch 47 and two parallel circuits to the fuel pump 10, a control switch 76 in one circuit that closes and energizes the fuel pump when the starter switch 28 is closed, a second control switch 42 in the second circuit actuated by the engine lubrication pressure and closed when that pressure is normal, a resistance circuit in parallel with the second circuit and including an indicator device 70 that has a resistance sufficient to reduce the voltage across the fuel pump to less than that necessary to actuate it, and operates when an abnormal fall of lubrication pressure causes the switch 42 to open and break the second circuit and also when the ignition switch is closed prior to engine starting. The switch 42 comprises a casing divided into a pressure chamber 55 and a switch chamber 56 by a diaphragm 54 carrying a spring-loaded plunger 60 having an insulated tappet 63 thereon caused by lubrication pressure below the diaphragm 54 to press against a spring arm 43 and close contacts 40. 59. The indicator device is shown as a lamp 70 but may be a bell or buzzer. When the engine is not in operation the switches are in the open positions shown. Upon closure of the ignition switch 47 current flows from the battery 23 through the lamp 70 and the fuel pump 10 to earth at 36 but the pump does not operate due to the current limiting effect of the lamp. The engine is started by closing the starter'switch 28 which, in addition to energizing the starter motor 22, energizes and closes the switch 76 to short circuit the lamp 70 and connect the battery direct to the fuel pump which then operates to supply fuel to the carburetter. When the engine starts the starter switch is released and the switch 76 de-energized and opened but lubricant pressure from the oil pump 15 acting beneath the diaphragm 54 closes the switch 42 and current still flows direct from the battery to the fuel pump via the switch 42, the lamp 70 again being shortcircuited. If during engine running the lubrication pressure falls below the allowable minimum the plunger 60 is retracted by its spring 64, the switch 42 is opened and the circuit to the fuel pump includes the lamp 70 which affords a visual warning and reduces the current to the pump so that the latter stops and the engine comes to rest. Specification 631,283, [Group XXVII], is referred to.

Abstract: 856,881. Reservoir pens. ESTERBROOK PEN CO. April 2, 1957 [April 9, 1956], No. 10694/57. Class 146(3). A fountain pen comprises a feed-bar having an internal duct wholly within its body extending through its entire length and communicating at one end with the ink reservoir, the duct providing communicating capillary ink and air channels in juxteposed relation of which the ink channels are located on that side of the air channel nearest the nib, the feed bar also having a transverse slot of capillary dimension underlying the nib and communicating with the capillary ink channels. As shown the feed-bar 10 is formed of extruded plastic material of circular cross-section having an internal duct of U- shaped cross-section which provides a capillary air channel 15b and ink channels 15a of slightly greater capillarity. The transverse slot 17 of greater capillarity than the ink channels 15a is cut in the upper part of the feed bar and intersects the ink channels to convey ink therefrom to the underside of the nib. A longitudinal capillary groove 21 is also provided on the upper surface of the feed-bar underlying the forward end of the nib and is intersected by the slot 17. Semi-annular capillary grooves 18 are cut in the underside of the feed-bar to serve as overflow chambers for any excess of ink which has been fed to the underside of the nib through the channels 15a, slot 17 and groove 21. When the pen is inverted the ink in the grooves 18 returns to the reservoir along the feed passages mentioned above. The air channel 15b is blocked in front of the slot 17 by a plug 22 of metal or plastic, air being fed to the channel 15b via the open front ends of the ink channels 15a. In a modification annular capillarygrooves extending completely round the feedbar replace the grooves 18, and the groove 21 extends backwards beyond the front end of the nib-section. A method of making the feed-bar is described wherein a blank of material extruded with the internal duct therein is held horizontally by a member which enters the air channel 15b at the front end of the blank while a notch 30 is cut in the rear end of the blank.
