Filed: 1940-10-17
Abstract: 544,678. Heat treating sillicon steel sheets. WILLIAMS, W. P. (Armco International Corporation). Oct. 17, 1940, No. 15408. [Class 72] [Also in Group XII] For the purpose of decreasing the brittleness of silicon steel sheets, they are annealed in an atmosphere which at least as early as the soaking period is kept low in hydrogen and any source of hydrogen such as water. The atmosphere may be mainly nitrogen and any hydrogen produced is oxidized by the addition of air and the product removed preferably during the circulation of the atmosphere, during which hydrogen is also removed. During the middle or latter portion of the heating up period the atmosphere is maintained in a nearly neutral condition with respect to iron and iron oxide by adding oxygen so as to maintain a substantially non-reactive balance of CO and CO 2 . The annealing may be carried out at a temperature above 1350‹ C. and terminated with a slow cooling within the temperature range 1650-1350‹F. Specification 429,940 is referred to.

Title: Start air control system on an internal combustion engine
IPC: F02N99/00
Filed: 1975-04-16
Abstract: 1467204 Controlling air at starting of IC engines BENDIX CORP 16 April 1975 [28 May 1974] 15667/75 Heading F1B and F1H A start air control system on an I.C. engine having an air intake duct with'a throttle valve 38 movable between a substantially closed and a fully open position and a cranking system for starting the engine comprises a temperature sensor 26 for generating a signal indicating the engine temperature, the signal being fed to a reference signal generator 30 which produces a temperature dependent reference speed signal which is supplied to a comparator 32 along with a signal from a sensor 28 for sensing the engine's actual speed. The comparator 32 generates a termination signal when the actual engine speed is equal to or greater than the reference speed and the termination signal is used to reduce the air-flow to the engine below that which is used during starting. In Fig. 3, closure of ignition switch 20 energizes a solenoid 54 to open throttle valve 38 to a start position shown. When the actual engine speed reaches the value indicated by the reference speed signal, the output from the comparator 32 actuates latching relay 58 disconnecting the solenoid 54 and connecting coil 66 direct to power source 22 and spring 68 closes throttle valve 38 to a position determined by cam 52 and follower 50. The rate of closure of the throttle valve is governed by a dashpot 70. In Fig. 4, (not shown) dashpot 70 and solenoid shaft 56 both act on the throttle valve 38 by way of an arm (74). In the embodiments in Figs. 6, 7 (not shown) and 8 a vacuum motor 80 connected via tube 90 to the engine intake manifold is provided. In Fig. 6, when the ignition is switched on, shaft 56 is extended to the position shown to hold, with the assistance of spring 92, the throttle valve 38 in the start position. When the engine starts the diaphragm 82 retracts rod 98 away from arm 42 and the shaft 56 is retracted when the engine reaches the necessary speed. In Fig. 7 (not shown) rod 98 is kept in the illustrated position by lever (104) until shaft 56 is withdrawn when the engine speed is high enough, enabling diaphragm 82 to move rod (98) leftwards to allow the throttle valve 38 to close. In Fig. 8, a by-pass around the throttle valve 38 is open during starting to supply extra air to the engine and, when the engine reaches the required speed, solenoid 54 is de-energized so that shaft 56 is retracted, opening valve 114, 118 to allow manifold vacuum to act via tube 90 to close the by-pass valve 130. The rate of closure is governed by the size of restriction 134. Instead of using a latching relay, a bi-stable flipflop (136) may be used, Fig. 9 (not shown). The start air control system may be used in an engine fitted with either a carburetter or electronic fuel injection equipment.

Abstract: 1,206,266. 266. Rotary positive-displacement pumps and motors. GENERAL SIGNAL CORP. March 27, 1969 [June 12, 1968], No.16020/69. Heading F1F. A rotary positive-displacement fluid-pump, or motor, of the externally-meshing gear-type has a pressure-loaded axially-movable wear-plate 18 abutting end-faces of gears 15, 17, the side of said plate farthest from the gears being divided into two separate areas by a sealing member 37, which areas are subject to the pressure of working fluid leaking across the outer edge of the plate from an inlet port 38 and an outlet port 39, respectively. The member 37 is made of a relatively hard material e.g. phenolic resin, and is partially lodged in a groove within an end cover 12 of the housing, which groove contains a sealing member 27 of channel cross-section and made of an elastomeric material, a similar, but thicker, sealing member 24 rendered integral therewith being situated in said cover radially beyond the wear-plate. The member 37 prevents extrusion of the member 27 and has its ends abutting shoulders, or steps, 35 formed in the member 27 adjacent the member 24 to obviate leakage thereat. Lubrication of shafts 14, 16 for the gears is effected by leakage of working fluid from the region of the port 39 through grooves (22, 23), Fig.6 (not shown), in a bronze face (21) of the wear-plate adjacent the gears. A resilient dam 41 in a groove within the cover 12 abuts the wear-plate and restricts the flow of fluid from the shafts to the inlet port 38 across the back of the wear-plate.
