Title: Improvements in or relating to propellers
IPC: B64C11/36
Filed: 1920-07-08
Abstract: 170,342. Oddy, W. D., and Adderley, W. J. July 8, 1920. Screw propellers.-Relates to variable-pitch screw propellers, and consists in actuating the adjusting-mechanism by means which can be effected by the revolution of the propeller shaft under automatic and manual control. The means may comprise a star-wheel on the propeller which is normally free of arms on a bell-crank lever attached to the engine casing or other fixed part, the arms being movable into the path of the star wheel for giving it relative motion for the purpose of moving the blade-adjusting mechanism. A second lever frees the first bell-crank automatically after the desired pitch alternation is effected. Worm-wheels 6, Figs. 1 and 2, are keyed to the spindles 5 on the shanks of the blades 50 and engage worms 12, which are geared by spur-wheels carrying, externally to the boss, a star-wheel 15. In a fixed pedestal 27 is mounted a hollow shaft carrying at one end a bell-crank lever 23, Fig. 5, with rollers 24, and at the other end is a lever 28 having a pin 29 adapted to engage a recess in a rod 30 pivoted at 31 to a second link 32 pivoted at 33. The free end of the rod 30 passes beneath a rod 35 held down by a spring 36, the rods being connected to a hand control lever. A shaft, mounted in the hollow shaft, has at one end a lever 39 with roller 40, and at the other end is a lever 41 which bears against the rod 30. A spring-controlled plunger 43 abuts on a flat on the centre of the bell-crank lever which maintains the crank in its neutral position. A positive lock for the crank in any position is provided at 46. To adjust the blades, the rod 30 is moved up or down and the lower or upper roller 24 is thereby brought into the path of the sprocket, which is accordingly rotated and in turn moves the blades. Immediately after a tooth on the sprocket has been engaged, the boss engages the roller 40 on the lever 39, thus raising this lever and the lever 41. The latter raises the rod 30, releases the pin connection 29 on the lever 28, and the bell-crank lever is returned to the neutral position by the spring pin 43. The hand control of the rod 30 is then reset to neutral so that it engages the pin 29. By locking with the pin 46, the bell-crank lever is not set back to neutral after one contact with the sprocket, but is maintain in position and the sprocket is thereby continuously rotated.

Title: Redundancy reduction
Inventor: CANDY J C
IPC: H04N7/32
Filed: 1971-06-09
Abstract: 1326450 Television redundancy reduction WESTERN ELECTRIC CO Inc 9 June 1971 [15 June 1970] 19692/71 Heading H4F In a television signal redundancy reduction apparatus of the type in which only the samples of picture element amplitudes that have changed significantly from one video frame to the next are selected by an encoder for transmission and in which a buffer memory and address signals are utilized, to prevent the buffer memory being overloaded during periods of increased activity in the televised picture an overload signal is generated after a predetermined number of samples have been stored in the memory, which signal inhibits the storage of further samples either from the whole picture frame or from a border portion around the picture frame for a given interval which is at least one frame interval, this inhibited border portion being gradually decreased in subsequent frames. The analogue video signal is first converted into a digital stream of samples which are stored in a frame memory, and each new sample is compared with its corresponding sample stored in the frame memory to produce an energizing signal if the difference between them is greater than that of a given threshold difference, this energizing signal causing replacement of the sample stored in the frame memory by its corresponding new sample. The value of this threshold difference is preferably increased the greater the number of selected samples stored in the buffer memory and reduced to zero when the number of selected samples stored in the buffer memory is less than a given minimum. Further when the number of words stored in the buffer memory drops to a predetermined number initiation of the operation during which border blanking is gradually removed (i.e. one line at the top and bottom of the centre area and one column of picture elements at each side per frame interval) may be started before a set number of frame intervals have elapsed. The generation of an overload signal is indicated by means of a pilot light at the transmitter station, e.g. a video telephone set, which enables the subscriber to decrease his activity to re-establish the full field of view in the video picture or to confine a rapidly moving object to the centre area of the cameras field of view. Preferably the subscriber is also provided with a monitor which displays the same picture as is viewed by the receiver i.e. a frame repetition of the picture elements that are stored in the frame memory or a picture with a blanked border.
