IPC: C04B33/22
Filed: 1932-03-10
Abstract: 398,237. Making bricks. WANKLIN, A., 1, Claremont Avenue, New Malden, Surrey. March 10, 1932, No. 7215. Addition to 341,594. [Class 87 (i).] The method of making bricks, blocks, tiles, and like ceramic articles described and claimed in the parent Specification is modified by obtaining the mixture of hot burnt and unburnt clay for moulding by burning only a part of the clay subjected to the initial heat treatment, or by mixing alternate batches of burnt and unburnt clay from the same kiln. The raw material is first treated to remove stones, and then fed in the wet state to a rotary kiln and treated for a sufficient time for a portion only to be burnt. The mixture of burnt and unburnt clay thus obtained is led to a grinding mill, and subsequently is moulded and finally burnt as before.

Abstract: 140,095. Wagner, R. Jan. 25, 1919, [Convention date]. Suspended vehicles. -The body a, Fig. 1, of a suspended railway vehicle running on a double track is supported from the bogies c by means of pins g connected to the centre-piece of a cardan or like flexible joint situated above or substantially at the raillevel so as to permit the body to swing laterally owing to centrifugal force when rounding a curve, and also to adjust itself to any track irregularities. Coil springs g' may be arranged between the cardan joint and the frame of the bogie to absorb vertical shocks. When all the wheel pairs of the bogies are flanged or the rails are provided with guiding flanges, the pins g are arranged in their supports so as to rotate about a vertical axis, thus allowing the bogies to turn relatively to the body on a curve. As an alternative, the bogies may be prevented from pivoting on the pins g, in which case only one pair of wheels of each bogie is provided with flanges, or, if the rails are flanged, one pair of wheels is fixed while the other pair or pairs are capable of lateral displacement. In a modified construction, shown in Fig. 4, the bogie frame e is supported by four pairs of wheels, adjacent pairs having equalizing levers l connecting the supporting springs. In a further modification, Fig. 6, the body is supported from double levers n connected at their extremities by cardan joints with bogie frames m supported by springs and equalizing levers o.

Abstract: 674,233. Yarn clearers. BULMER & LUMB, Ltd., and KENNEDY, R. J. June 19, 1950 [March 17, 1949], No. 7270/49. Class 120(ii) A textile yarn clearer comprises a pair of clearing devices pivotally arranged in spaced relationship and to a relatively stationary concave bar, whereby both devices normally operate to clear the yarn but, which, upon the front device being removed for cleaning purposes, assures that the rear clearer still functions upon the yarn. As shown, a bar 2, with a concave upper surface, is attached to the bracket 1 which also carries a pivot screw 4 about which a spring-biassed plate 3 may swing. This plate carries a comb 6, spring-pressed at 7 and ad-) justably connected to the plate 3 at 5, and a blade 8, adjustably connected to the plate 3 at 9. The yarn in its passage through the double clearer contacts, also, an adjustable plate 14 on the bar 2 and a hardened cylindrical member 13. The clearer, which is fitted with detachable dust covers or guards 15, 16, is carried by an elongated plate which ensures that the moving thread must pass through the clearer and cannot be byepassed by an operative. When the comb 6 is moved forwardly for cleaning, the blade 8 swings to ensure that the moving yarn is still cleared by it. In a modification, the blade 8 may be so pivoted upon the plate 3 that when a slub contacts it, it will swing on the plate 3, trap the slub and break the yarn.

Abstract: 1283032 Automatic voltage control JOSEPH LUCAS (INDUSTRIES) Ltd 22 July 1969 7777/72 Divided out of 1283031 Heading G3R In a battery charging circuit, a thyristor connected in series with a battery to be charged receives gating signals from a two-transistor amplifier. The amplifier input is derived from a voltage sensitive device which turns on the input transistor when the battery voltage reaches a predetermined value. In the circuit shown, input transistor 52 is initially non-conductive and gating current for thyristor 44 can flow through transistor 54. When the voltage of battery 39 reaches a desired level, a Zener diode 49 breaks down and transistor 52 is turned on. Base current is thus diverted from transistor 54 and the thyristor gating current is cut off to halt charging of the battery unless its voltage falls below the critical level.
