Abstract: 746,635. Mine-roof arch struts. PRIEST & SONS, Ltd., B. March 13, 1954, No. 7378/54. Addition to 731,947. Class 20(2). The strut according to the parent Specification for bracing flanged metal supports of H, I or T-section in roofsupporting structures or arches for mines, is modified by providing means between nesting or overlapping limbs on the complementary clipparts, for positively fastening the overlapping or nesting limbs together after they have been tightened on to the flange and which must be released before the clip-parts can be disengaged The struts 5 are secured to an I-sectioned support 12 by means of clip parts 7, 8 having overlapping limbs 13, 16. The limb 13 has a notch with an inclined edge, Figs. 1 and 2 (not shown) and the limb 16 is provided with a bolt 17 adapted to engage the notch with its shank bearing against the inclined edge so that as the struts 5 are brought into line the clip-parts 7, 8 are drawn together to engage the web of the I-sectioned member. The bolt 17 is then tightened up to fasten the clip-parts together, and must be released before the clip-parts can be disengaged. Instead of a screw-threaded member, other positive fastening means may be employed such as a catch pivoted to one outer limb and having a flanged end which overlies an overlapping or nesting limb to prevent disengagement of the limbs unless the flanged end of the catch is first moved out of the way.

Title: Improvements in and relating to Circuit Arrangements for Dynamic, Radial Convergence in Television Receivers.
IPC: H04N9/28
Filed: 1967-02-16
Abstract: 1,175,221. Cathode-ray tube circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 Feb., 1967 [19 Feb., 1966], No. 7525/67. Heading H4T. In an arrangement providing dynamic convergence in the field scan direction of the R (red), G (green) and B (blue) beams of a colour display cathode ray tube a voltage having a parabolic waveform is developed across a potentiometer 7 (Fig. 1) in the anode circuit of the field output valve 1 and a voltage having a sawtooth waveform is developed via a winding 4 on the field output transformer 3. The overall amplitude of the resultant parabolic current in the convergence coils R and G is adjusted by potentiometer 7, and the relative amplitude is adjusted by potentiometer 14. In the case of the sawtooth voltage the direction and overall amplitude of the resultant current in the coils R and G is adjusted by potentiometer 8 whist the relative direction and amplitude is adjusted by mechanically coupled differentially operating respective potentiometers 10 and 11. For the blue convergence coil B the amplitude and direction of the parabolic current is adjusted by potentiometer 15 and potentiometer 9 allows a similar adjustment in respect of the sawtooth current. In order to ensure that a sawtooth current flows in the deflection coils 6 (connected to winding 5 on the transformer), that a pure parabolic voltage is produced across potentiometer 7 and that winding 4 operates virtually as a sawtooth voltage source a matching circuit comprising R4, C4 is employed to compensate for the load presented by the convergence coils and potentiometers. The method of determining the values of R4 and C4 in terms of such load is given and a non-mathematical analysis of the operation of the circuit of Fig. 1 is given with reference to equivalent circuit diagrams (Fig. 2 to 9, not shown). The parabolic voltage may be derived from a potentiometer replacing resistor 8 in the cathode circuit of valve 1 instead of from potentiometer 7, the connections to the coils R and G being inverted since the cathode voltage is of opposite polarity to the anode voltage and valve 1 may be replaced by a transistor.

Abstract: 468,868. Tipping- apparatus. NEW CONVEYOR CO., Ltd., and HOUGHTON, E. C. March 18, 1936, No. 8089. [Class 78 (iv)] The outer ring frame of a rotary tippler moves angularly relatively to and independently of the platform for supporting the wagon therein, during the initial stage of the tipping-operation, the movement being utilized to lock the wagon in position automatically. In the form shown the L - shaped platform k carries rollers o movable in slots p in the frame so that the initial movement of the frame in a clockwise direction brings supports w against the side of the wagon and also depresses the free ends of pivoted bars s through the medium of the members t so as to force the spring-pivoted members u into contact with the top of the wagon. Following this operation, the platform and frame move as a unit during the remainder of the tipping-movement and may be temporarily locked together at this stage on both tipping and return movements by a gravity pawl or wedge on the ring engaging teeth or a recess on the platform respectively. Fig. 4 shows a modification in which a gravity wedge 4 sliding in the slot 6 clamps a bar 5 in a recess in the platform k. The supports w carry rollers y running in slots and bearing against springs z, thus being mounted yieldably in the frame to permit the latter to rotate through a small angle after the supports have contacted the wagon, in cases where the platform does not commence to rotate immediately contact is established. On the return stroke, after tipping, the platform and frame revolve together until the platform abuts the stop q, following which the frame continues its rotation and releases the wagon.
