Title: Wear Compensating Ball Joints
Inventor: SCHEUBLEIN WILLIAM ARTHUR
IPC: B62D7/16
Filed: 1968-03-18
Abstract: 1,178,780. Wear-compensated joint. MOOG INDUSTRIES Inc. 18 March, 1968, No. 13089/68. Heading E2F. A joint which is self-compensating for wear comprises a housing 10 open at 12 to receive a stud 15 with head 16. The head of the stud is in contact with the thrust element 20 threaded externally at 22 and having spring fingers 29 which engage with a toothed ring 27 to prevent rotation of the element 20 in one direction. The thread 22 engages the inner thread 26 of the member 25 which acts as a reaction element and bears against a resilient ring 30 which is held between the reaction element and a stop plate 13 in a circular member provided with a ball or roller race 31 the balls of which act as distance pieces to prevent excessive deformation of the ring 30. In a second embodiment (Figs. 4 and 5 not shown) this arrangement is replaced by a magnetic ring which serves the same purpose. In operation, rotation of the stud in one direction tends to cause the element 20 to move towards the stud on its thread and take up any slack. It continues to do so until the frictional force between the stud and the thrust element exceeds that between the reaction element and stop plate when slipping occurs therebetween and further "unscrewing'' of the thrust element is prevented. The ratchet arrangement between the thrust element and the toothed ring prevents movement of the thrust element in the opposite direction which would slacken off the joint.

Abstract: 474,623. Valve generating circuits; television. COSSOR, Ltd., A. C., BEDFORD, L. H., and STEVENS, W. H. May 9, 1936, No. 13155. [Classes 40 (iii) and 40 (v)] A push-pull deflection voltage generator for a cathode-ray tube comprises a generator of exponential saw-tooth waves for the control of one deflector plate and an amplifier controlled from this generator, giving an output to control the other deflector plate ; the characteristic of the amplifier being such that the resultant saw-tooth voltage between the plates is approximately linear. Condenser C1, Fig. 1, is charged exponentially through resistance R1 from the 1500 volt source and is periodically discharged rapidly through the hard valve V2 which is normally biassed to cut-off by the resistance R7. Transformer windings L1, L2 are arranged to impress a positive voltage impulse on the grid when anode current flows, and a tertiary winding L3 is energized with synchronizing impulses to initiate discharges. The grid of the amplifier V3, normally biassed by the leak Rg, is fed with the saw-tooth oscillations by the potentiometer C2, C3, and a portion of the output is taken to the deflector plate PX2 through condenser CX2 from the potentiometer R3, R6. Inductance L4 compensates for stray capacities. The other deflector plate PX1 is fed through the coupling condenser CX1. A B C D, Fig. 2, represents the charging curve of C1, and CH the discharge ; the required voltage-time relationship between the plates being AE. The difference ex at any instant is shown by the curve FG and the amplifier V3 is so arranged to produce this curve of voltage-time relation on the plate PX2. According to the Provisional Specification, the input from a television radio receiver is applied to the grid of the synchronizing pentode V1, through a condenser C4. The filter R15, C15, C16 in the anode circuit separates the line and frame synchronizing impulses and causes them to appear separately across windings L3, L3<1> which are incorporated as tertiary windings of transformers in the line and frame signal generators.

Title: Automatic character-, character-recognition method
IPC: G06V30/224
Filed: 1962-04-06
Abstract: 949, 355. Automatic character reading. STANDARD TELEPHONES & CABLES Ltd. April 6, 1962 [April 12, 1961], No. 13359/62. Heading G4R. In a system for automatically reading characters the characters are printed as a pattern of striations (Fig, 1) each distinguished by the width, spacing or angle of the lines and they are compared optically with a number of striated screens as 5, Fig. 2 in order to obtain a recognition signal. The movement of the character past its matching screen causes a maximum amplitude signal to be developed in photo-diode 6,the signal having a frequency unique to the character depending on the slope and width of the lines. A frequency responsive circuit is connected between the amplifiers 7 and 8 and only one circuit gives an output. In the form of Fig. 3 the image number "23" on a moving envelope 9 is swept over a series of screens 12 by a rotating polygonal mirror 11. The output of photo-diodes 14 are applied to frequency selective amplifiers 15 and the output signals are applied to threshold circuits there being means in circuit (1) for determining the highest of the serially arriving signals to derive a threshold level. In Fig. 4 the character images are applied to masks 19 mounted on a rotating disc 18 which in effect scan the characters vertically, the record 9 moving horizontally. A single photo-diode 20 receives the light passing through the masks successively. The width and angle of the line forming the characters are adjusted so that only three characteristic frequencies are generated. Marks 27 on the disc are detected by a photo-cell 24 to step a counter 28 and open ten gates 26 in succession. The three selective amplifiers 22 are connected to all the gates and the highest signal produces an output from one of the threshold circuits 23.
