Title: An improved carburettor for internal combustion engines
IPC: F02M3/08
Filed: 1920-06-22
Abstract: 145,529. Tondeur, R. Oct. 8, 1917, [Convention date]. Fluid governors.-The Specification as open to inspection under Sect. 91 (3) (a) describes a carburettor in which the butterfly throttle valve 29, Figs. 2 and 4 (Cancelled), is of similar shape in cross-section to that of aeroplane wings to ensure thereon the maximum air thrust. The centre of pressure of the thrust is at one side of the pivot 31, Fig. 2 (Cancelled), the thrust tending to close the valve against the pull of an adjustable spring 32 acting through a cord 33 on a grooved cam 34 integral with a lever 35 on the throttle spindle. The movements of the throttle valve can be controlled manually through a slide 36, projections 37, 38 on which may engage a pin 40 on the lever 35. With the slide in the position shown in Fig. 2 (Cancelled), the pin 40 may move to any position between II and III. With increasing altitude the air density and therefore the thrust on the valve decreases, with the result that the valve tends to open and maintain the compression within reasonable limits. The movements of the throttle valve may be damped. The throttle valve spindle is made in two parts 31<a>, 31<b>, Fig. 4 (Cancelled), of which 31<a> is bored, screw-threaded, and split and 31b is coned and screw-threaded to.enter the bore of 31a and force it tightly into the hole in the throttle valve. This subject-matter does not appear in the Specification as accepted. Specification 110,477, [Class 7 (iii), Internal-combustion engines, Carburetting apparatus &c. for], is referred to.

Title: Improved method of repairing pneumatic tire casings
IPC: B29C73/08
Filed: 1945-07-04
Abstract: 594,920. Pneumatic tyres. HELLIER, E. July 4, 1945, No. 17006. Convention date, Sept. 7, 1944. [Class 144 (i)] A method of repairing ply-separation in tyre covers comprises enlarging the area of separation to render same more nearly uniform in shape, applying rubber adhesive to the separated surfaces, drying the applied adhesive by evaporation of the solvent, pressing the plies together and finally vulcanizing. As described and shown, the preliminary (further) separation of the defective part A of the plies is effected by means of pressure-fluid injected through a needle 14 from a supply-pipe 15, the fluid having been passed through a drier 18. Vulcanizable rubber cement is then injected to coat the separated surfaces and subsequently partially dried by blowing air through the needle. A vent needle 17 may be provided for the escape of excess cement and vaporized solvent.

Title: Improvements in or relating to sampling circuit arrangements
Inventor: MORTLEY WILFRED SINDEN
IPC: G11C27/02
Filed: 1961-05-10
Abstract: 966,569. Transistor sampling circuits; pulse radar. MARCONI CO. Ltd. Feb. 13, 1962 [May 10, 1961], No. 17011/61. Headings H3Q, H3T and H4D. A sampling detector circuit (for example, for a pulse radar system) comprises an input circuit such as tuned circuit Z producing oppositely phased oscillatory input voltages at two points connected through similarly poled rectifiers to a common point 6, and a series output loop from the common point including a load or resistor 8, a switching device, such as transistor 9, and an inductor 7. When the transistor is rendered conductive a rectified current builds up in load 8 until the voltage across the load is equal to half the voltage across capacitor 3. Thereafter, current decays reducing the oscillation energy to zero but continues through both rectifiers in parallel while the inductor field collapses. The resulting output pulse has a sinusoidal rise and an approximately exponential decay. The decay can, however, be terminated after an interval of twice the rise period by connecting across the load a transmission line section which returns a reflected pulse of opposite phase, delayed by the rise period and of amplitude equal to the original pulse after twice the rise period. Alternatively, a critical damping circuit may be connected across the load, or the load may be preceded by a low-pass filter. The capacitor C could be replaced by a capacitor connected across half the inductor 2 or by two capacitors, one across each half of the coil. A D.C. supply 14 in series with the emitter may overcome the " contact potential" of the rectifiers and a further D.C. supply may be connected in the collector circuit to bias the rectifiers in the non-conducting direction when the transistor is non-conducting and to remove effects to the capacitance of the rectifiers (Fig. 4, not shown). Other resonant circuits of the input circuit, e.g. X and Y, can be damped during the sampling period by a further transistor 112 or by the same transistor (Fig. 5, not shown). The associated radar circuit may be of the type described in Specification 948,763 in which a long swept frequency pulse is transmitted and the reflected pulse is divided in the receiver into portions covering a part of the range of the sweep.
