Abstract: 1528845 Determining particle size distribution COMPAGNIE INDUSTRIELLE DES LASERS 30 Jan 1976 [4 Feb 1975] 03869/76 Heading G1A To determine the size distribution of particles suspended in a liquid 24 the liquid is circulated through a receptacle 9 of sufficiently small crosssection for the particles to pass one at a time through a laser beam which forms a diffraction pattern in a focal plane 11, while a photo-multiplier 15 receives light from the pattern via an aperture 13, see Fig. 2 and a counter 18 counts the number of output signals of the multiplier whose amplitude exceed a threshold value set on device 19, the counting being repeated for different threshold values while a predetermined quantity of liquid circulates through the receptacle 9. The radii R 1 , R 2  of the aperture 13 are adjusted to be equal to the limits e.g. 33, 34, Fig. 3, between which, for the maximum diameter particles e.g. 8 microns, the percentage light energy within a diffraction circle of radius R increases linearly with R. The first threshold value is then set to correspond to the noise signal at the photo-multiplier with this aperture and subsequent counts are performed with higher threshold values. To count particles giving signals smaller than the above first threshold value a smaller aperture is used which lowers the noise signal and the procedure repeated. Calibration of the apparatus is carried out by circulating suspensions of particles all of the same known size and measuring the amplitude of the photo-multiplier output signal on an oscillograph 35.

Abstract: 547,684. Twisting airscrews &c. BRITISH OVERSEAS AIRWAYS CORPORATION and SAUNDERS, F. S. March 25, 1941, No. 4025. [Class 83 (iv)] A machine for twisting any preformed metal shape, particularly for resetting the blades of damaged metal air screws to the correct helix angle, comprises a stand on which a fixed and a slidable support are mounted carrying respectively an adjustable head and a fixed head, each head being provided with a torque plate on which is mounted a block carrying a pair of angularly disposed screws with self-aligning work clamping pads, and means for turning the adjustable head to twist the article. A stand formed of beams 1, 2 secured by plates 3, 4 and at one end being bolted to channel beams 5, 6 supported on legs 7, 8 and at the other end resting on a support 9, has clamped thereto a support 10 with an arcuate bearing member 11 for a semi-circular head 12 which is angularly movable in guides 14, 15 in the side plates 13. The head 12 carries a torque plate 16, which is connected by links 34 to hydraulic operating cylinders 31, 31x. A support 19 of box form and adjustable along the beams 1, 2 to vary the amount of the twist carries a torque plate 23. The torque plates have aluminium pads 71 and each carry four pillars 24 which support plates 25, 26 in which are mounted two pairs of hand operated clamping screws 27 provided with self-aligning pads 30. The air screw 70 is secured in the clamps 25, 26 and twisting effected by turning the head 12 by means of the cylinders 31, 31x which are operated by a motor driven pump 37 through a contact valve 35 operated by a hand lever 57 and a distributing block 36. If the lever is turned to the left, Fig. 6, a valve spindle 44 provided with a slotted disc valve 46 is pushed down by the element 56 so as to push a spring- returned ball valve 48 from its. seating. The pump which is connected by the pipe 62 with the post 55 is thus connected by passage 43 with a port 52 so as to be connected to the lower end of the forked port 60 in the block 36 from which one fork connects by passage 64 to the upper end of the cylinder.31 and the other fork connects by passage 65 to the lower end of the cylinder 31x so as to turn the head 12 to give a left hand twist. Exhaust from the other ends of the cylinders passes respectively from pipes 66, 67 through ports 61 in block 36 and thence by pipe 68, port 53 and slotted disc valve 47 through port 54 back to the pump by passage 69. If the lever 57 is turned to the right the valve 45 is pushed down to open valve 49 and port 55 is connected with port 53 and via port 61 to the opposite ends of the cylinders 31, 31x. The head 12 has a pointer 72 coacting with a scale 74 to indicate the angle of twist. The machine may be used to twist gun barrels so as to convert parallel into helical rifling.

Abstract: 1458015 Heat meters B J EDWARDS 28 Jan 1974 [26 Jan 1973] 4239/73 Heading G1D [Also in Division F2]  A heat meter 10 for measuring the quantity of heat extracted from or gained by a heat transfer  fluid flowing between inlet and outlet pipes 11, 12 of a heat transfer system such as a heating or refridgerating system includes means, such as orifice plates 13, 16 for diverting part of the fluid in the pipes 11, 12 through a fluid circuit containing two heat exchangers 24, 27 in which heat may be exchanged between the heat transfer fluid and an expansible, e.g. silicone, fluid, valves 19-22 for controlling the connection of the heat exchangers with the inlet and outlet pipes, valve actuating means operable in response to expansion or contraction of the expansible fluid to actuate the valves 19-22 to cyclically interchange the connections of the heat exchangers with the inlet and outlet pipes, and a register 43 to count the number of operations of the valves. As shown the valves are arranged in two gangs of two valves (19, 20), (21, 22) each. In operation, fluid is diverted at inlet 11 through a by-pass circuit comprising pipe 14, valve 19, heat exchanger 24, valve 20 and pipe 15, and fluid is diverted at outlet 12 through a by-pass circuit comprising pipe 17, valve 21, heat exchanger 27, pipe 28, valve 22 and pipe 18. The expansible fluid in heat exchangers 24, 27 forms the working fluid of cylinders 30, 33 having pistons 31, 34 acting on a pivotally-mounted beam 35. Pivoting of the beam 35 in response to differential expansion of the expansible fluid actuates the valve gauges and so diverts heat transfer fluid through the different heat exchangers. At inlet 11  fluid now passes through pipe 14, valve 19, heat exchanger 27, valve 20 and pipe 15, while at outlet 12 fluid passes through pipe 17, valve 21, heat exchanger 24, pipe 25, valve 22 and pipe 18. Thus the beam 35 oscillates at a rate depending on the rate of heat transfer between pipes 11 and 12. Register 43, linked by arm 44 to beam 35, counts the number of oscillations of the beam as a measure of the total heat transfer. Constructions of the valves 19-22 and their actuating means are described (See Division F2) by which the valves can be actuated and switched over quickly in response to the beam 35 reaching a predetermined position. Devices are also described Figs. 7 and 8 (not shown), for preventing vacuum formation in, and thus collapse of, pipes 29, 32 connecting heat exchangers 24, 27 with cylinders 30, 33.
