Title: Hydraulically actuated devices such as adjustable pitch aeronautical propellers
IPC: G07F5/24
Filed: 1955-10-18
Abstract: 813,266. Variable pitch propellers. UNITED AIRCRAFT CORPORATION. Oct. 18, 1955 [Oct. 19, 1954], No. 29677/55. Class 114. A hydraulically actuated adjustable pitch propeller, having a normal operating range and a special reverse pitch range, comprises means e.g., valve 68, for directing hydraulic fluid under pressure to actuate the device in the normal range and for directing hydraulic fluid under higher pressure to actuate the device in the special range, a special purpose valve, e.g., the valve 128 for applying the higher pressure to the piston 125 at the top of valve 68 for controlling operation of the directing means in the special range, and a selector valve, e.g., the valve 102, normally connecting valve 128 to drain via lines 120, 118 but movable to connect valve 128 with pressure fluid. Normally the speed governor 74 operates the piston valve 68 to direct fluid from pump 58 and line 64 to one of lines 24, 30 for actuating the pitch adjusting piston 22. Movement of the piston to the right under pressure in line 30 is limited by low pitch stops 36 held in position by a spring loaded cam 38 connected to a piston 42. Solenoid valve 72 is actuated to direct fluid to a piston on the lower end of the piston valve 68 for moving the piston valve for feathering the propeller. Solenoid valve 128 is actuated to direct higher pressure fluid to a piston 125 on the top of the piston valve 68 for moving the piston valve for reversing the propeller, but this cannot happen until the solenoid valve 102 is actuated. When valve 102 moves to the right higher pressure from pumps 58, 90 passes via lines 64, 116 to the rear of a high pressure relief valve 98 to prevent release of pressure in line 30, and, when valve 128 is moved to the left, to the rear of a low pressure relief valve 66 to hold it closed. High pressure fluid then passes the downwardly moved piston valve 68 from lines 64 to 30, into chamber 44 where it opens a spring loaded valve 50 and moves piston 42 to the right to release the stops 36. The higher pressure then moves piston 22 fully to the right to reverse the pitch. Specifications 636,402 and 683,906 are referred to.

Title: Improvements in Methods of Starting and Braking Electric Motors.
Inventor: BELLI CHARLES JOSEPH
IPC: B60L7/12
Filed: 1919-12-01
Abstract: 136,537. Belli, C. J. Dec. 13, 1918, [Convention date]. Systems for continuous-current motors only.- In a regenerative system for pairs of motors, the motors of each pair operate opposite sides of a differential gear; one machine acts as a generator and one as a motor during the early stages of starting, while the two machines act as motors connected in parallel during running. The armatures a, b of the machines A, Bare connected to the supply mains f, g through the switch c, but the field coils a<1>, b<1> are connected to the mains direct, the connexions being such that the machines rotate in opposite directions at the same speed. To start the actual driving of the locomotive or other machine, the field of the motor A is weakened. This increases the speed of the motor A and causes the machine B to run as a generator which is consequently retarded. This stage is continued until the speed of the motor A is double its former value. The field of the motor A is then strengthened to bring the current to zero, the switch e is opened and the field is weakened to cause the machine A to run as a motor. The machine B continues to run as a generator until it stops, and the excitation of the machine A is reversed. The machine B then runs as a motor with direction reversed and the machine A runs as a generator. The excitation of the machine A is increased until both machines are rotating in the same direction with the same speed. This second stage is of short duration so that the locomotive speed does not change materially during it. The machines are connected with their armatures in series across the supply during the third stage and finally in parallel across the supply. During the series connexion, the fields may be strengthened by means of the field coils a<4>, b<4>. For regenerative braking, the operations take place in the reverse order.

Abstract: 505,033. Making glass building-blocks. PILKINGTON BROS., Ltd. (Owens-Illinois Glass Co.) Nov. 3, 1937, No. 30134. [Class 56] Apparatus for uniting pairs of sections of hollow glass building-blocks comprises a number of platforms 23 and presses on a rotatable frame, means for retaining the pressure on a block during the pressing of one or more further blocks and means for discharging the pressed blocks onto a conveyer C leading to an annealing leer. The frame is held in definite stopping places against accidental displacement by spring-pressed members 18. The operator with the aid of the tool shown in Fig. 7, assembles a pair of sections, which are still plastic and the edges of which have been coated with a bonding material, on one of the platforms and actuates a pedal 57 to admit compressed air to the top of cylinder 51 of the corresponding press. The presser head consists of superposed plates 46 separated by springs, the maximum pressure being adjustable by means of a limit rod 61. The operator then rotates the frame to the next stopping position and assembles another block, pressure on the' previous one being maintained. In due course the first assembled block roaches the discharge position and the pedal 57 is tilted by a fixed cam 64 to cause compressed air to be admitted to the lower part of cylinder 51 to raise the press. Shortly afterwards a valve actuating member 39 engages a fixed cam 42 to cause the admission of compressed air to the inner end of cylinder 33 and so cause the movable portion 24 of the platform to assume the position shown at the right of the figure, and the block onto the conveyer C. Alternatively the block may be pushed off the platform horizontally.

Title: Improvements in or relating to sawtooth generators
IPC: H03K4/86
Filed: 1945-11-12
Abstract: 607,306. Saw-tooth generating circuits. PHILCO CORPORATION. Nov. 12, 1945, No. 30192. Convention date, Nov. 11, 1944. [Class 40 (vi)] In a saw-tooth generator, a capacitor is charged rapidly under the control of a triggering signal and discharged slowly through a device, the rate of operation of the discharge device being controlled by the frequency of the triggering signal. The charging and discharging functions may be interchanged. A triggering signal, applied to the square-wave generator 21, Fig. 3, causes thyratron 23 to fire and charge rapidly capacitor 14, the capacitor discharging slowly over the constant current pentode 27. The square wave is also applied to an integrating network 31, 32, the resulting triangular wave-form being rectified by diode 33 and smoothed by resistor-capacitor network 34, 35 to provide a bias for the control grid of pentode 27. An increase in the triggering frequency causes the bias potential to fall and the discharge rate of the capacitor to increase, tending to maintain the sawtooth amplitude constant. In a modification, Fig. 5 (not shown), a further control potential is derived from the voltage developed across the resistor 26 and applied through a D.C. amplifier to the pentode 27. In a further modification, Fig. 6, the main capacitor 14 is charged rapidly by a device 12 under the control of the triggering signal. The rate of operation of the discharge device 16 is varied by the potential developed across capacitor 55 which changes with variations in the triggering frequency. The triggering signal applied to the pulse generator 46 causes thyratron 47 to fire and charge rapidly capacitor 48, the rise in potential across resistor 49 firing thyratron 56 to discharge capacitor 55. Constant current pentode 51 subsequently discharges capacitor 48, the saw-tooth appearing at the anode being rectified by diode 53 to develop the control potential across capacitor 55. In a further modification, Fig. 8, the saw-tooth waveform is fed over cathode follower 63 to a diode 69, the rectified output being mixed with the output from the device 17 and applied to the control grid of pentode 27. The circuit, Fig. 3, may operate as a frequency divider when the switch 28 is near its upper position.
