Title: Improvements in devices for measuring the speed of aerial targets for purposes of anti-aircraft fire control
IPC: G01P3/02
Filed: 1931-06-26
Abstract: 378,603. Determining speed of aerial objects. NAAMLOOZE VENNOOTSCHAP NEDERLANDSCHE INSTRUMENTEN-COMPAGNIE, 44, Javastraat, The Hague.-(Assignees of Bergh, S. J. vanden; 17, Josef IsraÙlslaan, The Hague.) June 26, 1931, No. 18496. Convention date, July 3, 1930. [Class 106 (iii).] Apparatus for determining the speed of an aerial object according to the equation vg= v1 + v2/sin alpha + cos alpha (Fig. 1), is characterized by means by which the apparatus can be maintained in a condition in which (vl + vs) is kept constant assuming the velocity of the target to remain unaltered during temporary invisibility. The shaft 1 driven in known manner according to v and the shaft 2, driven in known manner according to vs cause, through gearing shown, the pointer 37 to indicate on the scale 38 values of (v- + vs and the friction wheel 48 to be displaced on a grooved shaft 46 from the centre of the constant speed motor-driven friction disc 49 a distance corresponding to (vl + vs), thus causing a vertical displacement of the pin 57 from its zero position through a distance corresponding to (vl + v,). The cam disc 65 is rotated by known means according to a and causes, through the engagement with it of the roller 64, a horizontal displacement corresponding to (sin alpha + cos a) in the guides 62, 63 of the frame 61 from a zero position. By these means a vertical displacement of the pin 69 corresponding to vg is obtained causing at the same time a similar vertical displacement of the pencil 74 on a drum 75 driven by clockwork 76. During observations the handle 89 is rotated to rotate the threaded spindle 88 to move the body 85 so that the record of vg on the drum 75 is kept between the forks 90 to cause, through the lever 78, slide 82, cord 93 and spring-controlled annular body 95, the mark 96 to follow the pointer 37. When the target is temporarily obscured the shafts 1, 2 are turned so that the pointer 37 remains coincident with the mark 96 thus causing the pencil 74 to remain in the position it occupied immediately before the target became obscured. If the working of the mark 96 with the slide 82 is disturbed during temporary invisibility of the target, the shafts 1, 2 are turned so that the indication of the pointer 37 on the scale 38 corresponds to the indication of the pointer 91, attached to the slide 82, on the scale 92.

Title: Improvements in or relating to liquid pressure servo-motor systems
IPC: F15B9/12
Filed: 1947-07-11
Abstract: 628,066. Fluid-pressure servomotor-control systems. AUTOMOTIVE PRODUCTS CO., Ltd., and BRADBURY, F. J. July 11, 1947, No. 18512. [Class 135] In a liquid-pressure servomotor, suitable for operating aircraft control surfaces, the servomotor is connected to a pressure liquid supply conduit 34 or to an exhaust conduit 35 through a main valve 47 which is closed as a result of a movement of the servopiston 13 resulting from an opening of the valve ; the valve being actuated by an auxiliary liquid-pressure servomotor system which includes a pilot valve 65 for controlling the supply of liquid to the auxiliary servomotor, the piston of which is a functional element of the main valve. The face 14 of the piston 13 and the chamber 86 are continuously open to the supply pressure. Movement of a hand-lever 22, Fig. 2, opens the pilot valve 65 through a link 23, a floating- lever 24 and a link 25, thus opening a chamber 66 to either the supply or exhaust conduits, causing the main valve 47 to follow-up this movement. Thus, the face 15 is connected by a conduit 83 with either the supply conduit, through chambers 44, 67, 43, or the exhaust conduit, through chambers 44, 68, 45. The resulting movement of the piston rod 11 recentres the pilot valve, and hence the main valve, through the floating lever 24 and the link 25, closing the chamber 44.

Filed: 1952-07-24
Abstract: 709,611. Engine starter cartridges. IMPERIAL CHEMICAL INDUSTRIIES, Ltd. Nov. 21, 1952 [July 24, 1952], No. 18765/52. Class 9(1) An engine-starter cartridge has a brass case with a thickened base 1 flanged to fit the breech of the enginestarter. In the base is an igniter housing 3 containing an electrical igniter 4 charged with fine grain black powderheld in place by a celluloid disc 17. Above the igniter is a muslin bag containing a kindling charge 5 of coarser grain black powder, the bag being cemented to the base of the annular main charge 7. The charge 7 comprises nitrocellulose with nitroglycerine, dibutyl phthalate, diethyl diphenyl urea, mineral jelly and potassium nitrate. Cemented to the base of the charge 7 are three stilts 9 of a colloided nitrocellulose-nitroglycerine composition faster burning than the charge 7. The cement may be made by dissolving the composition forming the stilts in acetone. Studs 8 of the same composition as the stilts 9 space the cylindrical surface of the charge 7 from the case thus leaving an annular passage for the flame gases which communicates through a radial channel 14 with the axial passage 15. A wrapping 16 of regenerated cellulose tape may cover the upper part of the cylindrical surface of the charge 7, the forward end of which is held in a steel spider 10. The arms 10<SP>1</SP> of the spider are bent at right angles to the plane of its annular web and are slightly dished at the bends. The central hole in the spider is of greater diameter than the axial gas passage 15 through the charge. Over the spider is placed a cellulose acetate sealing cup 11 which is covered with a cement before the cartridge case is bent over the spider to form a waterproof seal. A removable metal cap 13 may protect the end of the case during storage.
