Filed: 1953-01-22
Abstract: 730,994. Hypodermic needles. HUBER, R. L. Jan. 22, 1953, No. 1936/53. Class 81 (2). A hypodermic needle has a bend near its tip and the bevel extends across the bent portion from inside the bend. The heel at the back edge of the lumen, where it opens into the bevel, is relieved or rounded. In one form the needle 10 is bent, at 14, so that the point 12, formed by the bevel lies on the axis of the needle. The rear part of the orifice may be rounded off but, in order to allow a full diameter stylet 15 to be passed through the bore, the orifice is preferably cut back to provide a slot 17 so as to permit bending of the stylet. In this case the edges of the slot are rounded. In a modification shown in Fig. 6 (not shown) the angle through which the tip is bent is such that the surface of the bevel is parallel with the axis of the needle.

Title: Improvements in or relating to a method and devices for producing reinforced apertures in paper and the like
IPC: B26F1/36
Filed: 1948-01-22
Abstract: 660,118. Punching-machines. HIRSZSON, B., and PAPARELLI, J. A. Jan. 22, 1948 [Nov. 20, 1947], No. 1986/48. Class 31 (ii). A method for producing reinforced apertures in paper and the like using adhesive tape, comprises drawing the tape intermittently under a mechanism for cutting-out and perforating a portion or portions from the tape, and, when the tape is stationary, operating said mechanism while maintaining the tape under tension, then drawing unspent tape into the mechanism ready for the next cutting-out operation and finally applying the cut-out .portions to the material to be reinforced. As shown in Fig. 2, a machine for producing a pair of reinforced apertures in paper comprises a shaft 27 for supporting a roll of tape 30, cutting and punching mechanism housed within cylinders 3 and a shaft 17 carrying a roll 29 of used tape. Downward motion of a handle 20, pivoted at 21, causes a pawl on the end of the handle to engage a tooth in a ratchet-wheel 16 and to rotate the roll 29 so as to bring an unused portion of tape beneath the cutters. As the handle is moved down, a pin 10 thereon engages and moves a plunger 2 sliding within each cylinder 3, Fig. 3, each plunger 2 having an extension 2a, the motion being transmitted through spring 8 to a circular cutter 4 which co-operates with an aperture 51 in a die-plate 13 and into a circular portion from the tape 30. Further movement of the cutter 4 is prevented by shoulder 11 formed on the cylinder 3, spring 7 then acting on an annular applier 5, which, with continuing downward movement of the plunger, presses the circular cut-out portion of tape on to a sheet of paper 50 lying on the base 1 of the machine and beneath the die-plate, the applier then being arrested by the base-plate and the central stem 2a of the plunger then co-operating with an aperture 31 in the baseplate to punch a hole in the paper 50 and the reinforcing portion. The handle 20 is finally released and all parts restored to their normal positions.

Title: Pneumatically actuated apparatus for stabilizing the flight mach number of a moving body
Inventor: NERNER DANIEL
IPC: B64C13/48
Filed: 1960-01-20
Abstract: 937,757. Fluid-pressure servomotor control systems. NORD - AVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. Jan. 20, 1960 [Sept. 7, 1959], No. 2029/60. Class 135. A pneumatic apparatus enabling the stabilizing of the flight Mach number of a moving body whose propelling means uses atmospheric air and fuel and whose regulating installation, which delivers the fuel, dispenses the flow as a function of a reference air pressure, comprises the detection air circuit 1 in which the impact pressure Pd flows through an orifice 2 and becomes the reference pressure Pr which is fed to the regulating means, the reference pressure being determined by the leak past an adjustable valve 7 to an escape pipe 4 leading to a static intake tank. The position of the valve 7 is varied in accordance with the flight Mach number of the body by movement of a diaphragm 9. This diaphragm divides a chamber 10 into chambers 10a, 10b, the chamber 10a being connected by a pipe 11 to the static cone pressure Pc (this being the pressure of air flow past the apex of a cone carried by the body and trapped by the shock wave), while the pressure in the chamber 10b is a fraction of the flight impact pressure Pd flowing past a normally fixed, adjustable valve 12 and leaving the chamber 10b through an orifice 16 controlled by a needle valve 8. Both the valves 7 and 8 are connected to the diaphragm. In operation the initial setting of the valve 12 determines the predetermined flight Mach number and when the speed exceeds this value the pressure in the chamber 10b exceeds the pressure Pc causing upward movement of the diaphragm with consequential opening of the valves 7 and 8. The opening of the valve 8 reduces the pressure in the chamber 10b until equilibrium of the diaphragm is obtained and the opening of the valve 7 reduces the reference pressure Pr and hence the quantity of fuel delivered. If -the speed falls below the predetermined flight Mach number the converse occurs and the valves 7 and 8 are gradually moved towards a closed position, thus increasing the fuel supply.

Abstract: 100,104. Dushman, S. Feb. 20, 1915, [Convention date). Vacuum tubes. - To avoid distortion of an incandescent cathode bv the electrostatic field, in a tube exhausted so highly that there is no perceptible positive ionization, the anode is arranged substantially symmetrically about the cathode. In one form, a straight cathode filament of tungsten is held by tungsten leading-in wires, one of which is coiled for resilience, within a narrow tungsten tube forming the anode. Molybdenum rivets attach the anode supporting-rods of tungsten or molybdenum, which are provided with molybdenum anchors within side tubes. The envelope may be of sodiummagnesium boro-silicate. Such a tube may be used for rectifying at 10,000 volts and ¢-¥ ampere. In another form, suitable for a similar pressure and currents of about 1/10 ampere, a short helical filament is arranged within a cup-shaped anode. Fig. 3 shows a tube suitable for ¢ ampere and 50,000 volts. A V-shaped cathode filament 23 is mounted within a frame 24 of glass or molyb. denum connected to one of its ends, and is held at its apex by a spring insulated from the frame by mica strips. The frame 24 is carried by a molybdenum stem attached to a molybdenum or iron tube 39 inserted in a glass socket 40. Two anode plates 25, 26 are supported symmetrically on opposite sides of the filament by molybdenum rods 27 carried by a plate 29 on a tube 30. In an arrangement suitable for pressures up to 100,000 volts, a short straight cathode filament 41, Fig. 4, within a cylindrical anode 42, is held at one end by a wire 43, partly coiled, and at the other by a yoke 46 secured to a disk 47. This and another disk 50, which supports it by means of rods 48, surround the filament and wire 43 and shield the cathode seal. A clamp 52 insulated from the cathode wire 43 by mica clips the rods 48 to hold the wire 43 in axial position During the final stages of exhaustion of such tubes, current of increasing pressure is passed, but is interrupted if a blue glow due to liberated gas appears. In working, current increases with pressure up to a maximum current dependent on the temperature of the cathode. Specifications 14892/13, 220C/14, 15788/14, and 1694/15 are referred to.
