Abstract: 367,800. Pit props, piles, and like supports. BROMFORD TUBE CO., Ltd., Wheelwright Road, Erdington, Birmingham, and SPENCER, R. W., Rothwell, Walmley Road, Sutton Coldfield. Nov. 21, 1930, No. 35082. [Class 20 (ii).] Relates to tubular metal pit props, piles, and like supports of the kind having one end pointed or rounded and the other end substantially flat. According to the invention, the support is formed, by pressing or like operations, of a metal tube having one end a, Fig. 1, pointed or rounded and the other end b, Fig. 2, provided with an integral laterally-extending flange c. Each end of the tube in turn is brought to a welding temperature and a hollow die is then applied, the operative surface of which is preferably partly oval or conical. The temperature is such that the walls of the tube unite under the pressure of the die and are thereby thickened during this operation. One end of the tube is then placed within another die the walls of which encircle but are spaced clear of the tube. The end is again heated and a male die, having a slightly domed operative surface, is applied, thus flattening this end of the tube and spreading the metal out laterally to form the flange c.

Abstract: 1472999 Counterbalancing HITACHI Ltd 19 Aug 1974 [20 Aug 1973 2 Nov 1973 (2)] 36411/74 Heading B8B [Also in Division G3] When a load 10 is raised by means of an electric motor 28, the torque #l needed in the steady state is given by #l = #w + #f, where #w is a torque sufficient to balance the weight of the load and #f is needed to overcome friction. However, the weight always act downwardly and the frictional forces act upwardly or downwardly in accordance with the direction of the load movement. Hence #l = #lw Œ |#f|. The invention proposes to control a loadraising installation in accordance with the above theory by generating a command torque #p to correspond with #w plus a friction-compensating torque #fc whose magnitude is related to #p and whose sign depends on the direction of load movement (sensed by a speed transducer 28). The means employed comprises electrical circuitry, Fig. 4 (not shown, but see Division G3).

Abstract: 1,240,010. Phase comparators; colour television. NIPPON ELECTRIC CO. Ltd. 31 July, 1968 [11 Aug., 1967], No. 36498/68. Headings H3A and H4F. In a circuit for comparing the phases of two signals applied at 1, 2, the output from the comparator 4 is fed back via an integrator 6,- e.g. an amplifier and low-pass filter, to control a variable phase shifter 5 in at least one of the signal paths. The resulting output at 3 is dependent only on high-frequency variations in the phase difference between inputs 1 and 2. The circuit is employed in a colour shading compensator for a video recording system. During each colour burst, the phase of the subcarrier signal is sampled, and that of one line is compared with that of an adjacent line by feeding the sampled signal directly to one input of the comparator, and feeding it to the other via a delay equal to the time period of one line. The comparator compares the direct and delayed signals during the sampling periods, to produce an output waveform corresponding to the phase difference between the two input signals. This is applied as a control signal to a ramp generator producing a signal 103, Fig. 5, having the ramp slopes proportional to the magnitudes of the phase difference at each sampling instant. This signal is then used to produce a correction signal to adjust the horizontal line length so as to reduce colour shading.
