Title: Improvements in or relating to fluid heating systems
Inventor: MCLEAN DONALD
IPC: F02C7/224
Filed: 1961-08-08
Abstract: 946,710. Heat exchange apparatus. ROLLSROYCE Ltd. Aug. 1, 1962 [Aug. 8, 1961], No. 28669/61. Heading F4S. [Also in Division F1] A fluid heating system, for example a system for heating fuel flowing from a storage tank to a gas-turbine engine, comprises two temperaturesensing means which sense the temperature of the fuel to be heated respectively at a point upstream of and at a point downstream of the fuel-heating means. The two temperaturesensing means are arranged to actuate control means whereby the amount of heat supplied to the fuel is varied so that the temperature of the fuel at the outlet from the heating means remains substantially constant and so that no heat is imparted to the fuel when the temperature sensed by the upstream sensing means exceeds a pre-determined value. In the embodiment described the fuel flows through a line 10 to the heat exchanger 11 and discharges therefrom through line 12 to the engine. The fuel is heated in the heat exchanger by hot air taken from the engine compressor and passed through line 14 and control valve 15, the air after passing through the heat exchanger being discharged at 16. Temperature-sensing means 20, 21 are disposed in the lines 10, 12 respectively, the sensing means 20 being connected through a resilient coupling 22 to one end of a lever 23, the sensing means 21 being connected to an intermediate point on the lever, while the other end of the lever is connected to the stem of a double-seated valve 25 which controls the flow of heated air from the line 14 into the heat exchanger 11, the valve 25 being urged in the opening direction by a spring device 26. Specifications 749,684 and 874,251 are referred to.

Title: Improvements in or relating to float-actuated valves
Inventor: SHORROCK CHRISTOPHER
IPC: F16K31/20
Filed: 1951-12-07
Abstract: 773,571. Float-actuated valves. FERGUSON HOLDINGS, Ltd., H. March 9, 1953 [Dec. 7, 1951], No. 28705/51. Class 135. A float-actuated valve assembly, comprises a casing 1 having main and auxiliary float chambers 2, 3 housing floats 6, 17 operably associated with main and auxiliary valves 7, 13 respectively. The chambers 2, 3 are separated by a weir 4 and the main valve 7 which regulates, for example, the supply of fuel oil to atomizing burners is located downstream of the valve 13. In the event of the valve 7 not properly closing, overflow from the chamber 2 raises the float 17 to close the valve 13 which thus cuts off the oil supply to the burners to prevent them being flooded. The burners are finally extinguished, thus warning the operator that a flooding condition has occurred. Specifications 655,281 and 655,282, [Group XI], are referred to.
Patent GB-747011-A (GB)
Title: Improvements in the recording a reproduction of signals representative of an optical image
IPC: G11B5/53
Filed: 1951-12-10
Abstract: 747,011. Television. COUTANT, A. C., and MATHOT, J. Dec. 10, 1951, No. 28796/51. Class 40 (3). Relates to the magnetic recording and reproduction of electrical signals representative of an optical image. In accordance with one aspect of the invention, Figs. 1 and 2, the signals, which are derived by scanning in the usual way by means of a conventional pick-up tube 1, are recorded in a pattern of lines running transverse a strip-like magnetic recording surface 5 by means of a plurality of heads 7 carried by a rotating wheel 3. The heads are spaced around the periphery of the wheel by a distance corresponding to the length of line to be recorded, and each head is supplied with the image signals via commutator 11 during the period it traverses the recording surface. The heads are shaped so that their effective gaps correspond to the height of a line and the magnetic strip is advanced through a distance equal to the height of one line during the time one head traverses the strip. For reproducing signals previously recorded on the strip, pick-up tube 1 is replaced by a conventional imagereproducing cathode-ray tube. In a typical construction arranged to record or read 400 lines of 18 mm. in 1/25 sec. the wheel carries 100 heads, has a diameter of 60 cms. and rotates at 6000 r.p.m. In accordance with another aspect of the invention, Fig. 7, a plurality of wheels 13-16 carrying magnetic recording heads 18 is employed with the wheels spaced apart by a distance equal to 4n+1 lines where n is an integer. The recording strip is moved through a distance equal to four times the height of a line during the time taken for a head to traverse the strip whereby the lines due to the wheels interlace. The arrangement is operated with a pick-up tube with its target sub-divided into vertical sections, each of picture point width. Sections 1, 5, 9, &c. are connected with wheel 13, sections 2, 6, 10, &c. with wheel 14, sections 3, 7, 11, &c. with wheel 15, and sections 4, 8, 12, &c. with wheel 16. The wheels may rotate at onequarter the speed employed for the single wheel arrangement. Thus, in an arrangement employing wheels as above with 100 heads to record signals corresponding to a 400-line optical image repeating 25 times per second, the wheels rotate at 1500 r.p.m. Each head of the four heads operative at any one time deals with only one fourth of the image line being analysed, and it is not until four lines of the image have been analysed that each head will have recorded a full line on the magnetic strip.
