Title: Hydraulic turbine
IPC: F03B3/04
Filed: 1923-03-13
Abstract: 218,709. Moody, L. F. March 13, 1923. Axial-flow type; combined-flow type ; blades; working-fluid supply.-In a hydraulic turbine having means for directing the flow to the runner as in a reaction turbine the back surfaces of the blades are formed so as to cause a parting of the flow therefrom, air being admitted at suitable points to assist the effect. The vanes may be formed with lips 30 behind which are recessed portions 31, the flow parting from the blade at the rear edge of the lip. In the arrangement shown in Fig. 4 the edge of the lip is opposite the rear end of the adjacent vane so that beyond a line b the water is discharged as a free jet. In the application of such vanes to a turbine having a runner 12 of the reaction type as shown in Fig. 1 and having guide vanes 15, air is drawn in through openings 25, the supply being controlled by a hand-operated valve 26 and by a checkvalve operating when the pressure around the runner rises above atmospheric pressure. Air may also be admitted to the tips of the vanes from a passage 51 so as to allow the flow to separate from the sides of the outlet when the turbine is operating at a restricted gate opening. In the modification shown in Fig. 5 in which a core c is employed in the outlet air may be admitted round a sleeve 65 through openings 72 and a pipe 70, through openings 51<1> in the throat near the vane-tips, and through a pipe 70<1> having an outlet at the apex 72<1> of the core c. The flow is controlled by a plunger-gate 58 operated by a piston 59. If the pressure of the runner is above atmospheric pressure air under pressure may be admitted.

Title: Improvements in or relating to master cylinder units for liquid pressure control systems
IPC: B60T11/20
Filed: 1938-03-08
Abstract: 513,639. Hydraulic transmission of power. CLEVELAND, F. J. (Bendix Aviation Corporation). March 8, 1938, No. 7286. [Class 69 (ii)] [Also in Group XXXIV] In a hydraulic master cylinder comprising a main piston and one or more floating pistons which divide the cylinder into compartments each of which is connected to a set of brakes or other devices, means are provided whereby a pair of adjacent pistons become joined when pressed together through failure of the hydraulic pressure between them. The end piston may become similarly attached to the cylinder end. The length of the connection between the operating pedal and the main piston may be automatically adjusted when the pistons connect. A floating piston 32 divides the working space of the cylinder into compartments 33, 34 which as shown, are connected through outlets 19, 15 to the rear and front brakes respectively of a vehicle. The main and floating pistons 23, 32 are positioned respectively by pins 55, 46 which enter grooves in the pistons. Chambers 33, 34 are normally connected to the reservoir 11 by passages through the pins 46, 55 and the pistons, mushroom valves 50, 54 which close the piston passages when the pistons are moved being normally held open by engagement of the valve stems with the pins. Each valve has a rubber skirt 53 to form a seal. If in applying the brakes, the pipe line connected at 15 to the front brakes fails, a socket 40 on the piston 32 is forced on to a tapering spigot 41 on the cylinder end 14 thus preventing return of the piston. Similarly it the pipe line connected at 19 to the rear brake fails the pistons 23, 32 are joined by the socket and spigot 38, 37. To permit return of the pedal 57 to the normal position in this case, the thrust connection between it and the piston 23 is automatically extensible and comprises balls or rollers 66 adapted to wedge between a tapered part 65 of the member 63 and a socket member 62 to transmit the thrust, while during the return stroke, after the piston 32 has engaged the pin 46, the socket 62 slides on the member 63.

Title: Improvements in or relating to frequency transformation devices
IPC: H03B19/03
Filed: 1957-03-08
Abstract: 862,426. Semi-conductor frequency divider circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 8, 1957 [March 13, 1956], No. 7750/57. Class 40(6) [Also in Groups XXXV and XXXVI] A frequency divider comprises a plate of a material of the type in which the current flowing therethrough may be varied by means of a magnetic field, mounted in a gap in the core of an inductor, the input signal being applied to a non-linear circuit including the inductor and the output being derived from the plate. In Fig. 1 a Hall effect plate 2 is mounted in a gap of a ferrite core comprising a semi-circular part 1 and a rod portion 1<SP>1</SP>. The core is wound with a coil 3 which is fed from an input signal source 5 via a resistor 15 and a capacitor 4. By arranging that the core is saturated by the signal and by suitably choosing the value of the capacitor 4 and resistor 15 it may be arranged that the flux passing through the Hall plate 2 has a large sub-harmonic component. The plate is connected at two opposite sides to a battery 6 and at two further opposite sides to output terminals 14, where the sub-harmonic voltage appears. In order to ensure that the input signal is not applied to the circuit at a point when the input wave passes through zero, a starting circuit comprising a rectifier 11 and a relay 8 is provided. When this relay operates the signal is connected to the circuit by contact 9 and a contact 9<SP>1</SP> brings a capacitor 10 into the circuit to maintain the relay operated. The input circuit 3, 4 is preferably tuned to a frequency lower than 0.66 of the input frequency and preferably to the sub-harmonic. Fig. 5 shows an alternative arrangement in which the input coil 3, 3<SP>1</SP> is wound so that the difference in the fluxes produced by the two parts of the coil passes through the central limb and the Hall plate 2. By this means a strong even subharmonic component is obtained. An odd subharmonic may be obtained as shown in Fig. 6 by arranging the coil 3, 3<SP>1</SP> so that the sum of the fluxes passes through the central limb and the plate 2. In this instance a biasing flux is applied by a winding 23 which is parallel tuned to the sub-harmonic by a capacitor 24. The circuits may use a voltage generator 5 and a series tuned circuit as shown in Figs. 1 and 6 or a current generator and a parallel tuned circuit, as shown in Fig. 5. In an alternative arrangement (Fig. 3) a plate 16 of a material such as bismuth or indium antimony alloy is used, the resistance of which varies with the magnetic field and this is inserted in the air gap of the core in place of the Hall plate. The plate is connected in a bridge circuit which, in the absence of input signal, is balanced.
