Abstract: 1,207,071. Vertical lathes. HEALD MACHINE CO. 28 Feb., 1969 [4 March, 1968], No. 10894/69. Headings B3B and B3T.  A machine tool 10 such as a vertical lathe or boring machine comprises a base 14 in which are mounted spindles 42 carrying chucks 19 and 20, a tool carrying post 22 supported in a sleeve 33 parallel to the axes of rotation of the spindles and which is axially movable and pivotable in the sleeve about its longitudinal axis, tool holders 23 and 24 being mounted on the post and whereby the axial and rotary pivoting movements of the post effects predetermined movements of the cutting tools which engage workpieces 12 carried in the chucks 19 and 20. The axial movement of the tool post 22 is effected by cam and lever means 52, 41, 39, 37, 36, the link member 36 being connected to the lower end of a piston 53 in a coaxial bore in the post which permits extended travel of the post upwardly beyond that normally possible by the cam 52. The axial pivoting movement of the post is effected from a cam 51 and further by a pneumatic piston and cylinder unit 57 which is actuated in conjunction with piston 53 to turn the post away from the work spindles when the tools are to be changed. The cams 51 and 52 are selected depending on the particular movement required of the tool post so that the tools may be introduced to the workpieces to generate a surface of revolution. A portion 40 of the upper surface 15 of the base is inclined and joins with a shoot 32 to permit the disposal of chips and cutting fluid and coolant.

Abstract: 283,035. Munro, H. April 23, 1927. No Patent granted (Sealing fee not paid). Laying pipes.-Drains are formed in the ground and lined with sheet metal lining by means of a drain plough provided with means for carrying the lining, doubling it, and delivering it into the ground, the lining being anchored at one end and drawn off the plough as the latter progresses. The drain is made by a plug 1 carried by a hollow coulter plate 2 adjustably attached to a pivoted beam 3 which is provided with a supporting shoe 19 and is adapted to be raised by a rack or by a winch 17 on a wheel frame 3<a>. The lining strip 5 is made up into a. roll 6 and is passed through rollers or dies 7 which double it with its edges facing forwards and downwards. It then passes through a passage 9 and over a core 10 in the hollow plate 2, being finally widened out transversely by a suitably shaped part of the core 10. Soil is pressed down on the lining by a share 14. The final shape of the lining may be as shown in section in any one of Figs. 7, 8, 9, and 11. Longitudinal and transverse slits may be formed in the lining strip to facilitate doubling and entry of water into the drain. The edges may also be curved inwardly before the strip is made up into rolls 6. Lubrication may be provided where the strip engages the core 10 and plate 2. The core 10 may be omitted. The doubling-rollers 7 are driven by chain gearing 29, and may be toothed to engage slots or corrugations in the lining strip. A driven wheel provided with teeth or flattened parts may be mounted in the hollow plate 2 to assist in moving the lining strip. Two separate strips may be used for lining one drain. A second strip is indicated at 25 in Fig. 7. A coulter may be mounted in front of the plate 2. According to the Provisional Specification the lining may be made of material other than sheet metal, its edges may overlap, and it may be shaped entirely above ground or entirely below the ground surface.

Two insulated wire springs forming the headband of a telephone headset pivotably support at their ends two ear-pieces, enabling angular adjustment of the ear-pieces to the wearer's head, and also provide electrical connection to an ear-piece on one side of the headset from terminals located at the other side. A pair of Helmholtz resonators within each earpiece amplify the sound from the ear-piece receivers. As shown in Figs. 1 and 3 a pair of spaced insulated wire springs forming the headband 12 support at their ends for angular movement two ear-pieces 1, 2 by means of lugs 14 which can slide on the wires and which are connected to the sides of each ear-piece by pairs of pins 14, 15. The telephone line is fed to terminals within the right-hand ear-piece 2 and is extended via the wire springs of the headband to the receiver of the left-hand ear-piece 1. A microphone boom 10 is supported for rotation by a ball-joint 11 on the right-hand ear-piece. The sound from each receiver is magnified by a pair of Helmholtz resonators (Fig. 3) comprising an inner cylindrical chamber 19 which communicates with an outer annular chamber 20 by holes 22. Further holes 23 in the annular chamber emit the sound. The back cover 7 of the left-hand earpiece is hinged to open and allow the wearer to hear external sounds.

Abstract: 999,977. Welding by fusion. UNION TANK CAR CO. March 23, 1962 [July 31, 1961], No. 11204/62. Heading B3R. Apparatus for seam welding using a welding head oscillated transversely of the seam includes a first means for adjusting the oscillation amplitude prior to welding and a second independent means for adjusting the oscillation amplitude during welding. In a gas, e.g. argon, shielded metal arc welding machine for making vertical welds between plates 13, 14 of an aluminium storage tank, the welding head 15 is mounted on a carriage 110 having rollers 140 engaging a grooved rail assembly 132 secured to the tank. The assembly 132 also has a rack 150 engaged by a pinion 151 driven by a variable speed motor 111 on the carriage. The welding head 15 is clamped on arms 34 extending from a plate 33 attached by a pivot 40 to a support 39. A variable speed motor 50 reciprocates a rod 84 by means of a variable throw eccentric 58 which provides a coarse adjustment of the transverse oscillation of the welding head 15. A block 90 attached by a pivot 91 to the plate 33 is connected to the rod 84. The distance between the pivots 91 and 40 is adjustable by means of a knob 104 during welding to provide a fine adjustment of the transverse oscillations. The support 39 is mounted on the carriage 110 in such manner as to be adjustable transversely of the weld by a rack-and-pinion actuated by a knob 112 and to be adjustable angularly about a horizontal axis so that the welding head 15 may be tilted backwardly relative to the directions of welding.

Title: Improvements in rotating bands for projectiles and methods for making the same
IPC: C22C33/02
Filed: 1957-04-08
Abstract: Rotating bands for projectiles are made by sintering powdered iron or carbon steel which has previously been heated in ammonia gas to 250-510 DEG C. to render the metal resistant to wear without increasing its hardness.  The sintering is carried out under pressure, for example 3 to 4 metric tons per square centimetre, and the temperature required for sintering may be lowered by chemically depositing 0.8-2.0 per cent by weight of copper on to the iron powder by immersion in an ammoniacal solution of copper sulphate which contains tartaric acid.
