Title: Improvements in or relating to tools for automatic capstan or turret lathes
IPC: B23B29/034
Filed: 1944-07-29
Abstract: 579,585. Turning. COLEY, S. E. July 29, 1944, No. 14519. [Class 83 (iii)] A tool rest, for use in conjunction with automatic lathes, of the kind in which relative axial movement between a head portion and a body portion causes a tool to move radially into engagement with the work, comprises a tool 23 carried by a block 18 mounted for direct sliding movement in a guideway formed in an end face of the head portion 13, the block being actuated by contact with an inclined face 29 on a member 30 projecting axially from the body. The body portion 11 is adapted to be carried in an automatic or like lathe and is bored axially over a part of its length slidably to receive the shank 12 of the head portion 13. A spring 14 maintains the shank 12 in a projected position limited by the head of a stop screw 16. One end of the slide block 18 is recessed for a spring 19 which maintains a projecting peg 29 at the other end in contact with the wedge member 30. A cover 27 retains the slide in its slot and when the cover engages a portion of the work or a fixed abutment to produce relative movement of head and body portions, the tool is fed radially into the work. The cover-plate 27 may be of hard metal or may have a hard metal insert over its engaging portion. An alternative arrangement includes a spring-pressed abutment with a spring of greater strength than the spring 14 so that when the head engages the abutment relative movement takes place between the head and body to project the tool for starting the recess, then the two parts move together against the abutment spring to cut a recess of any desired axial length.

Abstract: 998,124. Welding by pressure. P. S. KNUDSEN, and E. JOHANSEN. April 16, 1962 [April 17, 1961], No. 14688/62. Heading B3R. In ultrasonic cold-welding two objects a weld exceeding in extent a single spot weld is produced by bringing one of the objects into direct contact with a sonic head or with a sonotrode rigid with the sonic head over the total extent of the weld and applying oscillations to the object in any direction other than at right angles to the abutting surfaces of the object. The flanges 68, Fig. 3, of a rectangular section metal container to be closed are arranged between a horizontal sonotrode 58 carried on a holder 44 adjustably supported on an upright 42 and a pressure head 48 carried on a handoperated lever 50 pivoted on a support from the holder 44. The vibrator for the sonotrode 58 is also carried by the holder 44. In an embodiment for simultaneously sealing a cover to a cylindrical container and welding the side seam of the folded sheet container, the container is supported on the sonotrode 74, Fig. 6, forming a mandrel and a pressure head 80 having an annular flange 82 to press against the cover and a downwardly extending finger 84 to press against the side seam is swung down by operation of a cam 98. Separate pressure heads may be provided for the two welds. In welding a cover to a. container already having a bottom the latter is supported on a bracket and the cover is contacted by a recessed sonotrode. For welding a recessed cover to a container the sonotrode is annular and supports the flange on the container, the cover being urged downwardly by a pressure head. The latter member may alternatively be the sonotrode. In welding two sheet metal members they are positioned between a plate on an hydraulic jack and a plate forming a sonotrode. A portable apparatus for welding a cover 152, Fig. 11, to a ball-bearing 154 comprises a sonotrode 148 having an annular flange 150, a head 144 and a vibrator 146.

[Also in Division A5] Novel phosphorylated dihydro - benzothiophenes and phosphorylated thiachromans of the general formula in which X is an O or S atom, A is a covalent bond or is a methylene group, R is alkyl, R<SP>1</SP> is H or alkyl, and n is 0 or 1 are obtained by reacting a phenol of the formula preferably in the form of an alkali metal salt, with a phosphorus halide compound of the formula (RO) 2 P(X)Hal wherein Hal is halogen, preferably Cl. The reaction is desirably carried out in an organic solvent especially methyl isobutyl ketone. The products have biocidal properties. The phenol of Formula II wherein A is a covalent bond and n is 0 is obtained by reducing the corresponding alkoxy-substituted benzothiophene, e.g. with sodium in ethanol, to form the corresponding 2,3-dihydrobenzothiophene and then dealkylating the product, e.g. by successive treatment with boron tribromide and water. When n is 1 and A is a covalent bond the phenol of formula II is prepared by oxidizing a corresponding alkoxy-2,3-dihydrobenzothio. phene with a stoichiometric amount of oxidizing agent, e.g. H 2 O 2  in glacial acetic acid, and then dealkylating the product as above, an example being given in which the alkoxy group is methoxy. 5 - Methoxy - benzo(b)thiophene is obtained by treating 5-hydroxybenzo(b)thiophene in NaOH solution with methyl p-toluene sulphonate and is then reduced with Na in ethanol under nitrogen to form the corresponding dihydro compound which is then dealkylated by treatment with boron tribromide in CCl 4 , pouring the mixture on to ice and extracting with ether to yield 5-hydroxy-2,3-dihydrobenzo(b)- thiophene. 4-Methoxyphenylthioacetone is obtained by reacting p-methoxythiophenol with chloroacetone in acetone in the presence of potassium carbonate and is converted to 5-methoxy- -3-methylbenzo(b)thiophene by dissolving in dry chlorobenzene adding dropwise a mixture of phosphorus pentoxide and phosphoric acid, heating, pouring into water and extracting the chlorobenzene layer with benzene. Reduction with Na in ethanol under nitrogen yields the corresponding 2,3-dihydro compound which is then dealkylated as above to yield 2,3-dihydro-5- hydroxy-3-methyl-benzo(b)thiophene. p-Methoxyphenylallyl sulphide is obtained by adding sodium to an ethanolic solution of pmethoxythiophenol and then treating dropwise with allyl bromide and is then refluxed in quinoline to yield a mixture of 5-methoxy-2-methyl-2,3- dihydrobenzo-(b)-thiophene and 5-methoxythiachroman which are separated and separately demethylated to form the corresponding hydroxy compounds.

IPC: H03B7/08
Filed: 1960-05-02
Abstract: 955,705. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 2, 1960 [Aug. 5, 1959], No. 15288/60. Heading H1K. [Also in Division H3] A sub-assembly with a fixed natural frequency of oscillation comprises an Esaki diode and another semi-conductor device in a closed circuit. One such sub-assembly is formed by applying dots of tin-gallium and tin-arsenic respecively to spaced areas of a degenerate arsenic doped N type germanium slab placed on a resistance heater. The slab is then rapidly heated and cooled to form alloy P+ and N+ regions within it. The dots may then be joined by a conductor to complete the unit. Alternatively after being soldered or brazed to a conductive base 46 (Fig. 16) the slab is selectively etched electrolytically to leave a pair of two zone bodies joined only through the base. A conductive plate 53 is next connected to the two dots and the sub-assembly mounted as shown on a conductive plate 54. As a further alternative the two two-zone bodies may be made separately and then mounted as shown. To increase the power handling capacity of the subassembly the P+ and N+ zones formed by alloying may be in the form of long parallel strips (Fig. 20). In spite of the increased junction capacitance of such an arrangement the natural frequency is not materially lower since the inductance of the broader conductive plate 73 and base 74 and the junction resistance are correspondingly reduced. In any of the above arrangements the N+ alloyed zone may be replaced by a P or degenerate P+ zone to give the resistive impedance element part of the assembly a conventional diode or Esaki diode characteristic. Another sub-assembly, Fig. 21, is formed from a cylinder of degenerate N+ material by diffusion of donors into its cylindrical surface to form a second N+ or P+ zone 78 and subsequent alloying of acceptor into the upper surface to form a degenerate P+ zone 77 contacting zone 78.

Abstract: 571,354. Turn-wrest ploughs. HURLIMANN, H. Sept. 18, 1943, No. 15346. [Class 6 (i)] Power indepen-. dent of that for driving the tractor is provided for swinging the shares of a turnwrest plough. A shaft 26 is mounted in a frame 51, 56 pivoted to a main frame 4 fixed to the tractor. Depth of working is determined by adjusting the height of the shaft 26 where it is journalled in the frame 51. The adjusting handle 66 is mounted on a threaded rod 67 passing through a nut secured to slotted rods 69 working over a pin traversing the shaft. Arms 31a, 31b, project from a sleeve 31 rotatably mounted on the shaft 26. The arm 31a carries the beam 35 supporting the shares. Adjustable plates 48 are provided the arms 31a, 31b. and are each provided with a notch 49. A latch 50 under control of a lever 55 engages one of the notches and locks the shares in working position. A second sleeve 25 on the shaft 26 is coupled to the sleeve 31 and is connected by chains 24, 7'to a winch 6 actuated by an electric motor 8. The coupling comprises two doublearmed levers 29, 29a pivoted on an arm 28 of sleeve 25. One arm of each lever forms a counterweight, the other is hooked to engage one of a pair of studs 32, 33 fixed to the sleeve 31. The chain 24 attached to an arm 21 on the sleeve 25 bends around the sleeve, either on one side or the other, depending on which share is in working position, and release of the latch 50 and starting of the winch automatically produces the required turning movement. Adjacent ends of the chains 7, 24 are connected to a lever 22 pivoted to an extension 23 of an arm 42 carried by a stub shaft 43 pivoted to the shaft 25. In a modification, the lever 22 is straight, and the chain 24 replaced by a slotted plate connected by a pair of links to the sleeve 31. A control rod 12 has one connection 13 which both operates the motor switch and slides its armature to bring gears into mesh, a second connection 16 operating the brake shoes 18 on the winch-drum 20, and a third connection 63 to a set-screw 61. Fig. 2 shows the position for travel on the road. For working, the lever 12 is depressed releasing the brake and permitting the plough beam and shares to fall. Too rapid a fall may be prevented by pushing the lever further than for mere release. To raise the shares the lever 12 is lifted, again releasing the brake, sliding the motor armature into gear, and switching it on. As the share is lifted the frame part 51 is tilted. bringing the stop 50 against the set screw 61, drawing down the rod 63 and the hand-lever 12, and thus immobilising the motor and braking the winch. Then to swing the plough the lever 55 is raised, withdrawing the latch 50 and leaving the sleeve 31 and beam 35 free to turn about the shaft 26.
