Abstract: 1,211,191. Pulse radar. MINISTER OF TECHNOLOGY. 29 Sept., 1952 [5 Oct., 1951], No. 23293/51. Heading H4D. In a pulse radar echo system, range and elevation are determined by five vertically coplanar receiving horns. The narrow polar diagrams of the horns lie adjacent to each other in the vertical plane and the output of each horn is applied, through an amplifier, to a deflecting plate of a cathode ray tube, the screen of which consists of sixteen sectoral plates. The signal developed at a plate is applied to an associated series of gates which open sequentially at times corresponding to target ranges so that a target echo pulse is admitted through the appropriate gate to the display apparatus. The range gates 22, 29 and 34, Fig. 11, are controlled by the multi-vibrators 21, 28 and 33 so as to be open during periods corresponding to consecutive target ranges. Target signals from the associated sectoral plate are routed via the terminal 23 through the appropriate gate to the height display through lead 24, 30 or 35. Each multivibrator operates the next one in the chain through a differentiating circuit, 26, 31. The operation of the cathode ray tube may be tested by the application of voltages to the deflecting plates from potentiometers rotated simultaneously by a cam operated mechanism.

Filed: 1928-08-14
Abstract: 296,024. Kiesselbach, C. Aug. 23, 1927, [Convention date]. Drawings to Specification. Steam regenerative accumulators ; hot-water storage apparatus.-One or more steam regenerative accumulators and hot water storage tanks are connected to the same boiler plant and when the steam consumption rises the hot water storage tanks are first brought into discharging use whilst the steam regenerative accumulators only begin to function when the heat output capacity of the storage tanks is insufficient to meet the increased consumption. Recharging may be effected in the reverse order, or the storage tanks may be first charged or both charged simultaneously. The steam pressure or preferably the direction in which it moves may be used as a guide to steam consumption. In an example, in which automatic connection of a steam accumulator and a storage tank depends on pressure variation, the storage tank is brought into circuit when the pressure has dropped to 1/10th atmosphere below the average and the steam accumulator is employed when the pressure drops a further 1/10th atmosphere. Separate portions of a battery of boilers may be connected to the steam accumulator and storage tank and a third portion to both.
