Title: A dual circuit brake system with antiskid control
IPC: B60T13/16
Filed: 1970-01-15
Abstract: 1,243,323. Antiskid systems. ALFRED TEVES G.m.b.H. 15 Jan., 1970 [17 Jan., 1969], No. 1968/70. Heading-F2F. In an antiskid dual braking system a displacement piston 31 moving in a cylinder 27 is interposed in an hydraulic line between a dual master cylinder 5 and a wheel cylinder 8 the piston being controlled by the pressure difference across a movable partition 25 which separates two chambers 29, 30 to increase the volume of that portion of the hydraulic line between the cylinder 27 and wheel cylinder 8 to release the brakes when a skid signal is detected by a rotary deceleration sensor 8<SP>1</SP> causing pressure fluid to pass to chamber 30. The pedaloperated master cylinder has a booster 21 supplied with hydraulic pressure fluid from a reservoir 1, and pump 2 through a throttle (not shown), the fluid also passing by way of a line 6, which may contain an accumulator 32, to an electromagnetic valve 26 which controls the flow of fluid to either chamber 29, 30. In normal operation hydraulic fluid from each of the master cylinder pressure chambers passes by way of lines 36 or 361 to wheel cylinders 8, 9 or 10, 11 respectively associated with a pair of wheels of a given axle by way of a valve 28 connected to piston 31. On detecting skid of a given wheel a signal is passed from the sensor to energize electromagnetic valve 26 which directs the flow of pressure fluid into chamber 30 thereby moving partition 25 and piston 31 leftwardly and closing valve 28, the increased volume in the line to the wheel cylinders relieving the brakes and pressure fluid in chamber 29 flowing back to the reservoir 1 via check valve 33 and line 34. When the valve 26 is de-energized pressure fluid is admitted to chamber 29 to restore the braking.

Title: Improved process of gaining iron from iron-containing ores with the formation of ferric chloride
IPC: C22B1/08
Filed: 1928-01-25
Abstract: 284,991. Vereinigte Stahlwerke Akt.- Ges.Feb. 7, 1927, [Convention date]. Extracting.-In a process for preparing iron, the ores are treated with chlorine or chlorinecontaining substances, e.g. vaporized hydrochloric acid, to produce ferric chloride, which is then reduced at a temperature of 300-500‹ C. by means of hydrogen after being freed from water. The reduction process may be added by the addition of spongy iron which acts as a catalyst, and the iron produced may be subjected to a magnetic concentration, any oxide residue being returned to the charge to be chlorinated. Instead of hydrochloric, acid, sodium chloride may be used. Arsenical or antimonial iron ores are subjected to a preliminary chlorination with chlorine or hydrochloric acid at 100‹ C. so as to remove the arsenic or antimony before the main chlorination. The Specification as open to inspection under Sect. 91 (3) (a) states that the chlorination is accelerated by the employment of a pressure of at least 10 atmospheres, and also that hydrochloric acid mav be replaced by magnesium or ammonium chloride. This subject-matter does not appear in the Specification as accepted.
