Title: Improvements in or relating to wind driven power plants
IPC: F03D11/02
Filed: 1927-12-19
Abstract: 307,559. Bucklen, H. E. Dec. 19, 1927. Actuating by liquid pressure.-The impeller 1 drives a rod 5 through worm gearing and a crank pin and rocking lever mechanism, Fig. 2. The rod 5 is connected to a pump plunger through a dash-pot device 6 so that, until the impeller is up to speed, the pump plunger is not actuated. The dash-pot comprises a cylinder 38, Fig. 3, connected by rods and a yoke 35 to the rod 5, within which slides a piston 39, fitted with a valve 40, which is connected by rods 48 and a yoke 49 to the plunger rod 50. The valve 40 is held away from its seating by adjustable spring pressure to permit the passage of oil contained in the cylinder 38 so long as the speed of the impeller, and therefore of the cylinder, is low; when a certain speed is reached the valve 40 closes, whereupon the piston 39 and cylinder 38 move rigidly together and the pump plunger is actuated. To ensure that the pump does not come to rest with the valve 40 closed, due to the piston 39 hanging on the oil, a leak groove is formed in the valve. Grooves 61, 60 on the piston 39 and cylinder 38 serve for lubrication and prevent escape of oil. The driving mechanism effects the down stroke in half the time of the upstroke. The worm reduction gearing may be 12/1 to 24/1.

Title: Eddy Current Testing System
IPC: G01N27/90
Filed: 1967-07-26
Abstract: 1,187,485. Detecting flaws electrically. AUTOMATION INDUSTRIES Inc. July 26, 1967 [Sept. 1, 1966], No.34426/67. Heading G1N. In the detection of flaws in metal articles, e.g. rods, tubes, the flanges on beer cans &c., using an eddy current detector, the sensing coil, through which the article is passed, is used both to generate measuring signals indicative of flaws and of the passage of ends of the article through the coil, and to generate signals indicative only of the passage of ends of the article, which latter signals are used to prevent the transmission of the measuring signals to e.g. an alarm system, a recorder or article rejecting device, for their duration. Thus the alarm system &c. is energized only by signals indicative of flaws. In the embodiment, a centre tapped sensing coil 30, Fig. 5, forms one common branch of a double A.C. bridge circuit, the other branches being provided by resistors 36, 38 and phase shift network 34 and by resistor 46, the outputs from the two bridges being taken respectively from terminals 40, 42 and 50, 52. The output 58, Fig, 6, from the first bridge, constituting the measuring signal is analysed in various known circuits (not shown), and only those signals whose amplitudes are greater than a present level are supplied to an alarm circuit &c. via circuits 80, 82, 88, 89, 92, and a gate circuit 70. This latter circuit only transmits the measuring signal if the input on line 76 from a Schmidt trigger circuit 68 is lower than a preset threshold which is arranged so that in one state of the trigger circuit the gate is open and the other the gate is closed. The trigger circuit is under the control of the amplified output from the second bridge output 62, its threshold triggering lever being set at such a value that it is triggered from the one state to the other only when the input signal results from the passage of an end of the article, all signals resulting from flaws having a level below the triggering threshold. Thus only those signals resulting from flaws in the article are transmitted through the gate circuit to the alarm circuit &c.
