IPC: A01M7/00
Filed: 1947-03-04
Abstract: 622,035. Crop-sprayers. PEST CONTROL, Ltd., DORMAN, A. K., and GLADSTONE, M. N. March 4, 1947, No. 6186. [Class 69 (iii)] A spraying machine has a spray boom articulated at two points forming two side portions pivoted at their inner ends to swing about vertical and horizontal axes, and to fold into a fore and aft position alongside the machine. In the embodiment a spraying ma. chine 1 carries at its rear a spray boom comprising a centre section 5 and two side sections 11, each side section having an outer section 26 hinged thereto by vertical hinges 27. The centre section, secured to slide blocks 4 co-operating with two vertical pillars on a fixed frame 2, may be moved vertically by a double acting hydraulic cylinder 6 anchored to the upper end of the frame. Each side portion 11 is secured at its upper part to a tubular support 9 rotatable about a post 8, and at its lower part to the support 9 via a double acting hydraulic piston and cylinder 17, Fig. 4, the piston 18 being pivotally connected to a cross member of the frame. Pressure fluid admitted or withdrawn from pipes 20 swivel the side portion upwardly about its upper trunnion. The swivelling support 9 is provided near its lower end with a lever arm 22 linked to the ram 23, Fig. 1, of a double-acting hydraulic jack, the remote end of the cylinder 24 being pivotally connected to the centre section 5. Pressure fluid admitted to or withdrawn from cylinder 24 swings the side section 11 from the extended to the folded position alongside the machine and vice versa. Each outer portion 26 has a lever mechanism 28 connected to a spring 31 and also connected by a cable 29 to a fixed arm 30. The movement of the inner side section 11 is thereby transmitted to the section 26 which folds against it. Spray bars 34 are secured to sections 11 and 26 and, if desired, to section 5. The positions of height adjustable castorwheels 25 may be varied along the sections 11. Specifications 557,068 and 587,484 are referred to.

Title: Improvements in or relating to the cutting of curved gear teeth
IPC: B23F9/10
Filed: 1935-03-01
Abstract: 455,853. Gear - cutting. FORSTER, A., 46, Via Cooperazione, Milanino, Milan, Italy. March 1, 1935, No. 6460. Convention date, March 1, 1934. [Class 83 (iii)] In a method of generating curved teeth of spur or bevel gears or segments of the teeth of hobs, broaches, &c., at least two milling heads K1, K2 are employed simultaneously on a rotating blank A, the cutter K1 cutting the concave tooth faces f and the cutter K2 the convex faces p. The head K1 is rolled relatively to the blank by the blank movement V along the line l and when the cutter points L1 reach a point somewhat beyond the mid plane W of the blank the faces f are completely cut. At the same time the heels T1 of the cutters rough out the metal between the teeth. During this movement the head K2 starting from the Fig. 1 position, cuts the opposite tooth faces, generation being complete when the cutter points L2 reach the mid plane of the blank, the heels T2 of this cutter also assisting in the roughing action. The total generating roll is thus approximately half that required for generating both blanks from a single cutter. The basic rotations of the cutters and blank depend upon the number of teeth to be cut and these speeds are modified by the rolling movements of the blank and cutter. Thus if the blank is moved in the feed direction V a generating rotation must be superposed so that it rolls on the cutter K1, the superposed velocity being positive or negative according to the direction of the feed. The two milling heads therefore rotate at different speeds which are so related that the resultant speed of the blank for correct co-operation with each cutter, such speeds being the sums of the cycloid-forming and the rolling generating movements, are the same in both cases. In a modification, Fig. 3, the tangential generating movements and the corresponding rotation about the blank axis D are both effected by the milling heads, of which K1, K3 and K5 cut the concave tooth faces and K2 and K4 the convex faces. By increasing the number of milling heads the feed speed may be doubled or trebled or each head may work every second or third tooth. As before the speed of each milling head is such the sum of the cycloid forming and generating speed of the blank is the same for all the heads. The feed speeds in directions V1-V5 may be different provided that the rotational speeds are suitably adjusted. Bevel gears are cut by milling cutters arranged as in Fig. 4, and adapted to swing around the blank pitch cone apex in the imaginary crown gear plane to perform the generating movement. In the case of bevel gears the directions of rotation of the head may be arranged so that one tooth blank may be cut to a right hand cycloidal line and the other to a left hand cycloidal line so that the tooth thickness may be varied in accordance with the varying diameter of the bevel gear.

Title: Steam generating unit
IPC: F22B21/34
Filed: 1965-02-16
Abstract: 1,089,922. Fluid-pressure servomotor systems. RILEY STOKER CORPORATION. Feb.16, 1965 [Feb. 25, 1964], No. 6627/65. Heading G3P. [Also in Division F4] A steam generator having eight burners 24, 25 and 62-67 is provided with a control system which maintains the air-fuel ratio at each burner at a predetermined value. The burners are arranged in two banks of four and each bank receives a fuel supply from a main line 75 via a main fuel valve 76. A valve 79 controls the amount of fuel passing to each bank, and valves 84, 97 divide the flow to each bank into two lines, each line serving a pair of adjacent burners in a bank. Further valves 88, 93, 102 and 106 divide the flow to each pair of burners into two further lines which serve individual burners. Air is supplied to each burner from a main supply duct containing a Venturi 41 Fig. 1 (not shown). The air-fuel ratio at each burner is determined by relays 113, 118, 121, 123, 125, 127, 129 and 132 which utilize orifices 51 and 109 provided in the air and fuel supply passages respectively. The output signals from the relays are representative of the respective air-fuel ratio 8, and these signals are received by a main controller 61 Fig. 3 (not shown). Output signals from the main controller actuate the valves 79, 84, 88, 93, 97, 102, 106. In operation, signals from the Venturi in the main air duct actuate a relay 44 which in turn actuates a solenoid-operated pilot valve 139 via a servomotor 135 and a rheostat 136. The pilot valve 139 controls a servomotor 141 connected to the main fuel valve 76. The signals from the pair of relays 113, 118 associated with burners 25, 62 are compared in a relay 153 (Fig. 3) and the output signal from this latter relay controls valve 88 via a servomotor 155, rheostat 156, pilot valve 157 and servomotor 89. Similarly, each of the valves 93, 102 and 106 is controlled by signals from the pair of relays associated with the pair of burners which the valve serves. A further relay 158 in the main controller compares the signals from relays 113, 118 with those from relays 121, 123 and actuates valve 84 via servomotor 161, rheostat 162, pilot valve 163 and servomotor 85. Similarly, valve 97 is actuated by a relay 164 which compares the signals from relays 125, 127 with those from relays 129, 132. Valve 79 is actuated by a relay 143 which compares the signals from relays 113, 118, 121, 123 with those from relays 125, 127, 129, 132, actuation of the valve being via servomotor 144, rheostat 145, pilot valve 146 and servomotor 81. The fuel may be gaseous, liquid or pulverulent. In the modification of Fig. 4 (not shown), the air flow to each burner is measured by means of a Venturi.

Title: Improvements relating to the prevention of back-firing in two-stroke multi-cylinder internal-combustion engines
IPC: F02D17/00
Filed: 1926-03-10
Abstract: 261,966. Fornaca, G. March 10, 1926. Induction pipes, fittings for; pumps, rotary.-In two-stroke multi-cylinder engines fed by a compressor from a carburettor, back-firing, due to running at low speed and reduction in pressure in the mixture supply pipe consequent upon sudden closing of the carburettor throttle valve, is prevented by a member which, when the accelerator pedal and the throttle valve are brought into the low-speed position, excludes from the compressor some but not all of the engine cylinders. The cylinders 1<1> - - 1<4> with exhaust ports 6 and inlet ports 7 are fed through a four-way manifold 8 with mixture drawn from a carburettor 10 by a compressor 9. The throttle valve 12 is actuated by a pedal 17 carrying an arm 16 adapted, when the pedal is released, to close the throttle, to engage a lever 15 which, through linkage 14, 14<1>, rotates a valve 13 to close the inlets to the three cylinders 1<2>, 1<3>, 1<4>, the cylinder 1<1> being permanently open to the compressor. Thus the engine is kept going by the cylinder 1<1>, the pressure supply to which is sufficiently high to prevent back-firing.

Title: Improvements in or relating to image intensifying devices
IPC: H01J31/50
Filed: 1955-03-08
Abstract: 770,238. Cathode ray tubes. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. March 8, 1955 [March 17, 1954], No. 6766/55. Class 39(1). An image intensifier comprises between the photocathode 2, Fig. 1, and fluorescent screen 21, a. target structure 12, Fig. 2, comprising an electron,a bombardment induced conductivity layer 15 and a photo-emissive mosaic 16, and a control grid or grids 17, 18 is or are arranged between the target structure 12 and the fluorescent screen 21, the electron BIC layer controlling the photo-emission from layer 16, The BIC material may be arsenic trisulphide, selenium, cadmium sulphide or anthracene. In operation an X-ray image is projected onto TuCdS fluorescent layer 6 the light from which passes through glass support 4 and transparent conductive layer 3 and excites photo-emissive (CS-Sb) layer 5 to produce an electron image which charges up BIC layer 15. The BIC layer 15 controls the photo-emission from CS-Sb mosaic 16 illuminated by light source 23 through shutter 24 so that a greatly amplified photoemission excites the fluorescent screen 19 which consists of ZnCdS layer 21 and electron permeable Al layer 22. Magnetic focusing means such as solenoids can focus the electron images on 12, 19, and grid 18 can be omitted or connected to grid 17. To obtain reduction of average image brightness without loss of detail brightness variations the light from 23 is pulsed or made intermittent by operating abutter 24, the charged areas of 16 discharging in the dark periods. The time interval between the light pulses can be chosen to increase the contrast at the desired brightness level. The potential of grid 18 can be varied to vary the minimum brightness level and the brightness range within which greatest contrast occurs can be adjusted. It is stated that by helping grid 18 at a few volts negative to grid 17 the contrast can be increased as well as the background brightness eliminated. In a modification, Fig. 3, the DC source 25 is replaced by a pulsating or AC source e.g. supplying a rowtooth wave, and the abutter 24 is dispensed with. The islands of mosaic 16 discharge when the voltage of the source is small and photoelectrons pass to fluorescent screen 19 when the voltage of the source is above a certain critical value. In further modifications the BIC layer may be heated e.g. to 500K. to increase its efficiency especially where the islands of 16 are thermionically emissive instead of photo-emissive ; 16 can be heated by an electrical and/or radiant heater. If fluorescent layer 6 is omitted the device can be used for intensifying light images e.g. in front of a pick up tube ; it is also suggested that fluorescent layer 6 can be used to emit light when struck by radiations other than X-rays.
