Abstract: 560,325. Optical apparatus. HILGER, Ltd., A., and DOWELL, J. H. Sept. 23, 1942, No. 13403. [Class 97 (i)] In apparatus for angle testing and gauging comprising a scale of angles, or other marking, in the focal plane of a collimating lens through which a light beam is directed on to a reflecting surface under test, the reflected beam being also received by the collimating lens, the resultant images are projected on to a screen for observation ; prism and scale combinations, means for locating the reflected beam, and means for facilitating viewing of the screen image, are also described. As shown, the instrument comprises a casing 9 carrying a collimating lens 10, a scale-bearing plate 6 in the focal plane of the lens, and a lamp 1, condenser 3, mirror 4, and prism 5 directing light through the lens 10. A scale 7, Fig. 4, is provided on the plate 6 at a position covered by the exit face of the prism 5, and a second scale 11 is provided thereon in a position such that the image of the scale 7 may cross it or lie near to it. A lens 12 and mirror 13 produce an image of the scales on a screen 14, and the screen may be observed through an aperture 18 and lens 15 by reflection in a mirror 17, or through an aperture 16 and the lens 15 only, the mirror 17 being tilted out of the position shown. The scales 7, 11 may consist of black or coloured lines on a light ground which may be coloured by the use of a filter. Alternatively, the scales may consist of bright lines on a dark ground, and the prism 6 and scales 7, 11, are then replaced by a prism combination 30, 34, 35, Fig. 5, and scales 38, 32. Light passes through the scale 38 to the collimating lens &c., and the reflected beam, forming an image above the scale 38, passes directly through a transparent reflecting surface 37 to the projection lens 12. A second beam from the lamp passes directly through the scale 32 and is reflected by the surface 37 into the lens 12. The background of one or both scales may be coloured; alternatively, gold or other substance reflecting a colour different from -that which it transmits may be provided on the surface 37. To facilitate location of the reflected beam, when the instrument is being set up, a matt white surface 28, Fig. 1, may be provided bearing lines between which the light patch is first caused to fall, adjustments being then made so that the reflected beam is received by the lens 10. Alternatively, a reflecting and imaging system may be provided to produce on the screen 14 a small scale image of the front of the scales 7, 11, and their surroundings, the screen 14 being observed, and adjustments made until the light spot is central thereon. Adjustments may be effected with the aid of a split bearing 21 for the collimator and a nut 22, the bearing being part of a support angularly and slidably adjustable on a slotted bar clamped to a base-plate at an adjustable angle.

Filed: 1926-05-29
Abstract: 274,243. Stewart, A., (Prokofiew, G.). May 29, 1926. Safety-valves.-One or more safety-valves, or a safety-valve and a feed-pump are controlled by a regulator comprising a stand M mounted on a boiler or other vessel under pressure and having a steam passage M<6> closed normally by one face of a double feed pilot valve R<7>. The double valve chamber M<3> communicates by a passage M<4> with a cylinder M<1> and by passages Q<2>, Q<3> with the atmosphere. A piston N fitted with piston rings or surrounded by a stuffing-box P<2> has a screwed extension N<2> and a reduced portion N' extending through a stuffing-box P into the boiler. The screwed extension N<2> has a split nut O having a pin O<1> and clamping screw O<5>, a slot in the nut O being slidable on a rib M<8> of the stand. The double valve R<7> is held to close the steam passage M<6> by a spring R<3> accommodated in a split tube Q having a spring regulating screw R<5> and a clamping screw Q<5>. When the steam pressure exceeds the normal the valve R<7> lifts and cuts off the cylinder M<1> from the atmosphere and opens it to the boiler pressure. This moves the piston N downwardly until the nut O comes against a stop M<7>. The pin O<1> transmits this movement to a valve which lets the surplus steam out of the boiler. The nut O may have a toothed rack which is geared to a valve. The Provisional Specification describes an arrangement in which a relay valve is arranged between the pilot valve R<7> and the cylinder M<1>, a piston in the cylinder M<1> normally holding closed a lift valve disc for passing excess steam from the boiler.

Title: Improvements in or relating to oil burning installations for heating systems
IPC: F23D11/10
Filed: 1926-05-31
Abstract: 262,657. Brunner, M. May 31, 1926. Oil supply.-In a heavy oil burning installation for the furnace of a heating system an electrically driven air pump 3 is used first for filling the oil tank 4 from a main reservoir F and subsequently for forcing the air by pneumatic pressure to the burner or burners E and supplying oil for mixing with and atomizing the oil or its discharge from the burner or burners. The air pump 3 has its inlet and exhaust valves 5, 6 connected by a loop tube 7 fitted with cocks 8, 9 and a closable air tube 10. The cock 9 is connected by a pipe 9<1> to a flue pipe 16 leading from a distributor chamber L to the outer atmosphere. The distributor L communicates with the supply tank 4 and is connected by a pipe 12 fitted with a valve 25 to the burner E. The lower part of the flue 16 comprises two branches, one 14 being fitted with a decompression cock 17 and the other with a safety valve 18. A pipe 11 leads from between the cocks 8, 9 on the tube 7 to the distributor L. The tank 4 communicates with the reservoir F through a valve-controlled pipe K, a flexible connection H and an adjustable dip pipe G having a filter J fitted at its lower end. A pipe 20 leads from below the fuel level in the tank 4 to a purifier 21 and a pipe 24 fitted with a cock 26 leads from the purifier to the burner E. The lower part of the purifier 21 is of glass and is fitted with a cock 23 for drawing off impurities. A manometer 13 is fitted on the distributor L. When the furnace is to be heated the tank 4 is first filled from the reservoir F by the suction caused by operating the air pump 3 to withdraw air from the tank 4 and discharge it into the flue pipe 16. For this operation the burner cocks 30<1>, 31<1> and the air inlet 10 are closed, the cocks 8, I are opened, and the twoway cock 9 turned so that the air discharged from the pump is led into the pipe 9<1>. When the tank is full the burner cocks 30<1>, 31<1> are opened, the cocks 8, I are closed, and the cock 9 turned so that the air discharged from the pump passes through the pipe 11 to the distributor L and then to the tank 4 and to the burner E. Spray burners.-The burner E shown in Fig. 4, comprises a tubular body 32, supported by a bracket 28 so as to project through the furnace door, and a forked head 29, the branches of which are connected through needle-valves 30<1>, 31<1> to the oil and air delivery pipes 12, 24, Fig. 1. A hollow spherical nozzle 35 provided with one or more discharge orifices 36 is adjustably secured in the delivery end of the body 32 by a nut 39. The oil passes through a tube 34 centrally arranged in the body 32 and the air through the annular space around the tube 34 to the spherical nozzle in which it is whirled before discharge by a mixer 37 having a cylindrical or spherical inner surface formed with helical grooves 38. The orifice or orifices 36 may be round, flat, or elliptical in section. The admission of additional air is regulated by an adjustable deflector 41.

Abstract: 200,292. May, H. May 16, 1922. Colour kinematography.-In order to compensate for the differences in the sensitivity of the eye for the basic colours used in three-colour projection, the component colour records are projected for different periods, the red being exposed for a shorter time than the green, and the green for a shorter time than the blue. Fig. 2 shows a rotary colour-filter screen used in projection, in which the area of the red sector 70 is smaller than that of the green sector 71, which is in turn smaller than that of the blue sector 72, these areas being approximately in the proportion 25 : 51 : 94. The opaque portions 80, 81, 82 are also of different areas as shown. Fig. 3 shows a filter having darkening sectors 90, 91 and an illuminating sector 92 in addition to the colour sectors. The sectors 90, 91 are of transparent grey glass, wire gauze &c. and arranged adjacent the sectors 70, 71, while the sector 92 adjacent the sector 72 is of frosted glass or other translucent material. In this case the total areas of the three openings are approximately equal.
