Title: Improved apparatus for controlling the flow of fluids
IPC: G05D7/01
Filed: 1940-12-06
Abstract: 547,733. Controlling fluid flow. PATERSON, W. Dec. 6, 1940, No. 17397. [Class 135] Apparatus for controlling the flow of a conditioning fluid, for treating a second fluid has the flow of the conditioning fluid controlled by a valve i actuated by a float g housed in an auxiliary chamber e to which there is an inflow of a secondary liquid normally balanced by an outflow or leak-away f. The inflow or outflow of the secondary liquid is controlled by an electrically actuated auxiliary valve l itself controlled by a potentiometer influenced by the conductivity or hydrogen-ion concentration of the treated fluid. Rapidity of response and great sensitivity may be secured by arranging a considerable continuous inflow and a large leak-away interrupted only when rapid adjustment is necessary normal correction being effected by control of a smaller leak-away. According to the Provisional Specification an apparatus for maintaining a constant rate of flow has the valve supplying liquid to the float tank controlled by a diaphragm-actuated valve subject to the pressure differential at a Venturi or like device in the main conduit. In place of the diaphragm a manometer type flow indicator may be used to close an electric circuit to actuate means controlling the supply or leak-away to or from the secondary chamber. The manometer may have a series of contacts adapted to be used selectively or it may be tilted to adjust the control point. The supply of secondary fluid may be controlled by temperature or humidity.

Filed: 1927-07-01
Abstract: 273,745. Ehmig, V., and Hofmann, F. July 1, 1926, [Convention date]. Helicopters; stopping way. - An aeroplane has a series of planes normally housed in a recess in one of the m a i n planes but adapted to be released to form a rotary retarding surface above the machine. In the case of a biplane additional surfaces are housed in the lower plane and hinge upwards into the air stream when released. Fig. 3 shows the machine after planes 7, 8 have been withdrawn from a recess 5 in the upper plane of a biplane to form a rotary retarding device, and after planes 9 have been permitted to rise against stops on the plane bracing. A streamlined central tube 3, Fig. 7, is secured to a frame 14 pivoted to the aircraft at 15 and having a pin 16 at its forward end normally locked at the lower end of a slot 17 on the aircraft frame by a hook 51. Two pairs of planes 7, 8 have central ribs pivoted respectively to two rings 12, 13 rotating about ball bearings provided on the central column. A spider 20 capable of sliding within the column has parts extending through slots 21 and carries ball races for the two rings 23, 26 carrying links 25, 27 which are pivoted to the central ribs of the planes 7, 8. Half-way slots are formed in the planes as shown in Fig. 10 to permit the passage of the links 25, 27. The spider has two projections 32 normally engaged by pivoted hooks 33, but when a cam 36 is moved by the pilot, the lower ends of the hooks are drawn together by a spring 45 to release the projections 32, and the spider 20 is raised by a spring 19 to raise the planes 7, 8. Simultaneously a spring 28 swings the pairs of planes into a position at right-angles to one another. Another cam 43 releases the hook 51 to enable the frame 14 to swing upwards until the pin 16 engages pawls 60 at the top of the slot 17 and simultaneously another hook 52 releases a spring-influenced lever 54 to turn a shaft 56 which releases the planes 9. Portions of the planes as shown at 8b, Fig. 10, may be given an inclination by varying the length of struts 61 to cause the planes 7, 8 to rotate. A screw 63 enables the spider 20 to be forced into its normal position again.

Patent GB-876631-A (GB)
Title: Record card processing apparatus
Inventor: STERN HANS M
IPC: G06K13/10
Filed: 1958-06-09
Abstract: 876,631. Feeding record cards. MAGNAVOX CO. June 9, 1958, No. 18408/58. Class 106 (1). [Also in Group XVI] In a record card feeding device, e.g. for a card collating machine, cards 10, Fig. 1, are fed from a stack 12 by a rotating suction drum which grips the cards in succession and carries them past a row of sensing devices 150 and a retaining device 90 is disposed in engagement with the top card adapted, when vacuum is applied, to prevent it leaving the stack, the retaining device being controlled by information read from the cards. The retaining device has a number of orifices 92 which transmit the suction in pipe 95 to the face of the top card. The suction is controlled by a valve 96, Fig. 3, which consists of a block having a transverse bore 100 in which slides a member 104 with a piston 106, 108 at each end. The bore 100 has vents at each end either of which can be closed by blade springs 130, 140, the member 104 being drawn by the vacuum in chamber 124 towards the closed end to connect the pipe 95 with the vacuum (as shown in Fig. 3) or to atmosphere. As shown in Fig. 1 the blade springs are fixed at one end and pass between the poles of magnets 136, 146. Current passed along the length of the blade moves it into or out of operative position. Sensing.-The cards may carry magnetically recorded data which is read by a row of sensing heads. A row of clock marks each denoting a card column is read by head 150 the signals being amplified and used to set a flip-flop 154, reset through delay line 156. The clock-pulse output from the flip-flop passes to a counter 160 which may be a trigger chain and is arranged to produce an output when the count reaches a predetermined value, which passes to flip-flop 162, another input being from signal source 164. Outputs from the two sides of flip-flop 162 control tubes 168, 176 which supply current to the blade springs 130, 140. Current in either blade causes it to rise and open the corresponding vent to bore 100, the piston element moving accordingly to apply vacuum or atmospheric pressure to the retaining device 90. A signal from source 164 sets flip-flop 162 and cuts off the vacuum from retainer 90 to allow the top card to leave the stack on drum 16. As the card moves the columns are sensed in turn by the row of sensing heads and the column marks by the head 150. The counter receives the clock pulses derived from the column marks and, when a predetermined number of vertical columns have been sensed, it produces an output to reset flip-flop 162 and re-apply the vacuum to the device 90 to prevent the next card being fed. In a modification the valve 96 has only one controlling blade spring, there being a source of air pressure connected to the bore to drive the member 104 to one end when the blade closes the vent, the member being returned to the other end by a spring when the vent is opened. Specification 876,630 is referred to.
