Title: Improvements in or relating to delay coils of variable electrical length
IPC: H03K7/08
Filed: 1954-04-30
Abstract: 752,013. Delay coils. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. April 30, 1954 [April 30, 1953], No. 12693/54. Class 40 (8). [Also in Group XL (c)] Parts of a delay coil are constructed elastically so that its electrical length can be varied by subjecting the parts to a tensile or compressive stress. Two oppositely directed windings 1, 2, Fig. 1, may be tightly wound on a rubber former 3 in such a manner that they are not movable relative to the rubber. It is shown in the Specification that both the inductance L and the capacitance C of the coil are substantially inversely proportional to the length of the coil former so that as the former is expanded the L/C ratio and hence the characteristic impedance remain substantially constant as the delay time of the coil is increased. The coil may have a single winding 2, Fig. 3, upon a tubular rubber former 1A into which is inserted a rod-shaped return conductor 3A. The two windings may be in the form of spiral springs either unsupported or supported upon a coil of rigid material. The delay coil of Fig. 3 may be disposed around the circumference of a drum one end of the coil being anchored to the drum and the other end to a fixed point in such a manner that rotation of the drum causes a change in length of the delay coil. In the arrangement of Fig. 5 several delay coils 1C are connected in series and arranged side by side between two supports 2B, 3B the latter of which is movable to effect variation in delay time.

Title: Improvements in optical interferometers
IPC: G01B9/02
Filed: 1936-05-07
Abstract: 474,809. Optical interferometers. WILLIAMS, W. E. May 7, 1936, No. 12867. [Class 97 (i)] In an interferometer particularly intended for testing and correcting lenses and other optical elements as described in Specification 130,224, [Class 97 (i)], light from the source of illumination is converged by a lens system so as to be focused on a light-dividing transparent reflector of very small area. Fig. 3 shows one form in which the convergent beam B is incident on the dividing reflector D, and the transmitted and reflected beams are returned to the mirror D, which thus acts also to recombine the beams, by systems M<1>, M<2>, each consisting of a collimating lens l<2> and a plane mirror m<3>. Either of both of the systems M<1>, M<2> may alternatively consist of a concave reflector having its centre of curvature at the mirror D. Fig. 6 shows a form in which a separate reflector D<2> is used to recombine the beams, the parallel beams emerging from the collimating lenses l<1>, l<2> being directed to the reflector D<2> by mirrors m<1>, m<3>. Converging lenses may be interposed in the beams B<4>, B<5> to enable a very small recombining reflector to be used. When lenses are to be tested for oblique rays by tilting them they may be mounted by means of nodal slides, forms of which are described in Specification 236,634, [Class 97 (i)], so that when tilted they are automatically displaced in relation to the mirror D to such an extent that the mirror always remains in the focal plane of the lenses. If the path differences to be measured are very great compared to the wave-length of the light, one of the systems M<1>, M<2> is replaced by an end gauge or K÷ster's unit. The dividing mirror D may'be made of a pair of similar contacting members such as the right-angled prisms p or hemispherical lenses l<5>, Fig. 8. Alternatively, the dividing mirror may consist of a metal film.

Patent GB-131622-A (GB)
IPC: B23G1/08
Abstract: 131,622. Marks, E. C. R., (Toledo Machinery Patents Co.). May 17, 1918. Screwing; chucks.-In a screwing-machine of the kind in which two thread-cutting units operate successively on tap or like blanks rotated in chucks on spindles mounted in a turret head, the second cutting die or unit 10 is mounted on a stem 8 slidable in the supporting member 7, and controlled by springs 15 on opposite sides of said member, engaging collars on the stem. The blanks are fed from a hopper 74, Fig. 2, by a cam 82 attached to a spring-controlled plunger 83 mounted on a bracket 84 on the sliding support 7, into one of the chucks 25 which is in the position A, Fig. 7, and in that position is held open by a cam 29. When the member 7 is retracted, a spring latch 67 engaging a sliding pin 53 withdraws it from a hole 54 in the drum 18 carrying the spindles 28 with chucks 25, and allows the drum 18 to be rotated by a worm 20 coupled frictionally to a pulley 23, until the blank reaches the position B ready for the first screwing operation, the spring-pressed fingers 78 yielding to allow the projecting end of the blank to pass, and a spring 28 closing the chuck jaws on to the blank as soon as the end of the spindle 26 is past the cam 29. The slide 7 is operated through change-speed gearing 42, a clutch 40, shaft 38, and pinion 37 engaging a rack 36 on a vertical slide 35 carrying a pivoted plate 45 the inclination of which can be varied by a screw 47 to vary the pitch of the screw-threads, and which engages a slipper 49 on the slide 7. At the end of the forward stroke, an adjustable stud 70 on the slide 7 engages a bar 69 and thereby releases the clutch 40 and allows a spring 44 and weight 50 to return the parts to their outer position. Just before the stud 53 reengages the drum 18, a cam 72 on the drum engages a stud 73 on the bar 69, and re-engages the clutch 40. The rotating cam elements 13, Fig. 6, by which the dies are operated, are held in the die-closing position against the action of springs, by projections 90 engaging stops 92 on a sliding bar 91, and are simultaneously released to open the dies by a cam 94 shifting the bar 91 against the action of a spring 93. The cam elements 13 are re-set by a bar 104 engaging pins 102 and actuated by cams 101 on the drum 18, through levers 98, 99. Oil may be fed to the dies through holes in the supporting spindles. The threaded blanks on reaching the position D are removed from the chuck which has been opened by the cam 29, by a screwed split collet 110. On the rearward movement of the member 7, a spring- pressed plunger 109 engages the part 3 of the frame and releases the blank by expanding the split collet 110.

Title: Improvements in and relating to the production of hydrosine
Inventor: SPENCER MICHAEL STAINES
IPC: C01B21/16
Filed: 1960-04-13
Abstract: N2H4 is produced by subjecting gaseous NH3 to an electric discharge in the presence of O2 in a minor proportion by moles relative to the NH3 taking part in the reaction and optionally a liquid.  The electric discharge may be spark, arc, glow, or corona used with A.C. or D.C., or A.C. with a field of constant alternating polarity, and the electrical energy may be in pulses and the A.C. may be applied capacitively or an electrodeless discharge may be used.  The liquid is water or anhydrous or aqueous NH3 and may be injected into the discharge as one or more jets or droplets, e.g. 0.2-2 mm. diameter, large enough to fall under gravity, or may be present as a pool, mist or falling film on the electrode or reaction chamber walls. The O2 may be fed to the centre of the discharge through a nozzle in the electrode, radially toward the axis of discharge from the periphery, through an annular opening outside one or more electrode or towards the cathode fall region of the discharge, and may be fed beneath the surface of a liquid.  Rate of feed of the O2 may be 40/400 moles/Faraday and the O2 may be mixed with NH3 or inert gases, e.g. A or N2, as air.  The gas pressure may be below 2 atmospheres, e.g. 5-100 mm. Hg, and the temperature below 1000 DEG  C.  The electrodes may be of or plated with corrosion-free metal or alloys, e.g. Pt, W, Ni, stainless steel or Ni or Cr plated Cu. A catalyst, e.g. for recombining H atoms or reacting H2 and O2 may be present in the reaction.  In an example, a heat resistant vessel fitted with 2 Pt electrodes was cooled to - 75 to - 78 DEG  C. and filled with NH3 at 50 mm. Hg.  Liquid anhydrous NH3 containing NH4 NO3 (for electrical conductivity) which may be in equilibrium with the gaseous NH3, immersed the plate cathode electrode which was vertically beneath the anode, in the form of a tube, which was fed with a mixture of O2 (0.012 mole/hour) and NH3 (0.04 mole/hour).  A D.C. discharge was struck between the electrodes and the liquid was then withdrawn for the N2H4.  Aq. NH3 is used to produce N2H4 hydrate.  Specification 735,655 is referred to.

Abstract: 856,091. Bitumen spraying systems. PARKER Ltd., F. July 24, 1959 [April 25, 1958; Sept. 17, 1958), Nos. 13220/58 and 29971/58. Class 107 [Also in Group XXIX] In a bitumen macadam or like plant the bitumen is delivered to the mixer via a spraying system designed to prevent the solidification of the bitumen in the system during periods between spraying. The system includes in series a bitumen heating tank 3, a pump 5, delivery line 1, a flow measuring meter 12, spray bar 6 and return line 2. The spray bar nozzles 7 are valve controlled by levers 8 from a common slide bar 9 and this bar also controls the spray bar valve 10 which closes the bitumen return path to the tank when the nozzle valves are opened. The slide bar is operated by a pneumatic cylinder 21 controlled by air valve 22. The bitumen flow through the meter 12 is controlled by a three-way cock 17 in one position of which the bitumen flows from line 1 through the registering mechanism 13 and via lines 18 and 19 to the spray bar and in the other position the bitumen flows from line 1 through the meter casing and via lines 16 and 18 to the spray bar. The cock is actuated by the pneumatic cylinder 20 which is also controlled by the air valve 22 such that the bitumen flows through the meter registering mechanism when the nozzle valves are open. During the periods between spraying the hot bitumen is circulated via the meter casing and spray bar keeping the temperature of the system above that at which the bitumen solidifies. A bleed pipe 24 incorporating an adjustable pressure operated valve 25 relieves excess pressure from the delivery pipe 1 and determines the spraying pressure. In a modification Fig. 6 (not shown) the bleed pipe and pressure operated valve are positioned in parallel with the spray bar. The spray bar valve mechanism Figs. 2 - 5 (not shown) (see Group XXIX) includes means for mechanically controlling the bitumen spray rate.
