Title: A method of and means for measuring and testing pneumatic tools, as for example pneumatic hammers and the like
IPC: B25D9/00
Filed: 1931-06-15
Abstract: 389,791. Dynamometers. GOSUDARSTWENNOJE VSESOJUSNOJE ELEKTROTECHNITSCHESKOJE OSJEDINENIIE VEO, 17, Maroseika, Moscow, U.S.S.R. June 15, 1931, No. 17364. Convention date, Aug. 16, 1930. Void [Published under Sect. 91 of the Acts]. [Class 106 (ii).] Comprises electric or electromagnetic means for measuring the power and number of strokes of pneumatic hammers. The hammer 17 is adapted to strike an iron leg 18 forming part of a yoke 2 which carries two coils 3, 4 in circuit with an ammeter 6 and regulating resistance 5 connected to a source of continuous current. Normally when the current is on, the yoke 2 is attracted to a fixed yoke 1 supporting coils 7, 8 in circuit with a voltmeter 11. When the hammer 17 strikes the rod 18 the yokes are separated but immediately are attracted producing an induced electromotive force which is measured bv the voltmeter 11 which may be calibrated to read power. To count the number of strokes in a given time the switch 12 is moved to the contact 14, and the induced current is used to energize an electromagnet 16 which attracts a pointed armature formed at a pawl 24 to turn a wheel 27 through one tooth at each reciprocation. The back stroke moves a pawl 29 to engage the wheel and prevent movement through more than one tooth by momentum. The wheel 27 operates a counter. The number of ohms may also be measured by a frequency meter, oscillograph, &c. The number of ohms may be measured by comparing the electromotive force induced in the secondary circuit with a known variable one derived from apparatus using a vacuum tube generator or a neon gas lamp. Again the gap between the tapper and rod may be illuminated by intermittent light and a stroboscopic method used.

Title: Novel dyestuffs for keratinic fibres
Inventor: BUGAUT ANDREE
IPC: C09F/
Filed: 1966-04-20
Abstract: The invention comprises a substituted p-phenylene diamine of formula <FORM:1088306/C2/1> prepared by reducing 1-methoxy-2-nitro-4,6-dimethyl-benzene to 1-methoxy-2-amino-4,6-dimethylbenzene, nitrating this to introduce a nitro group into the 5-position after first protecting the 2-amino group, liberating the 2-amino group and reducing the 5-nitro group. A preferred method involves reducing and acetylating 1-methoxy-2-nitro-4,6-dimethyl benzene to produce 1-methoxy-2-acetamido-4,6-dimethyl benzene, then nitrating with nitric acid to give 1 - methoxy - 2 - acetamide - 5 - nitro-4, 6-dimethyl benzene, de-acetylating the product with HCl and reducing the 5-nitro group. The substance is utilizable in hair dyeing (see Division D1).ALSO:Keratinic fibres, particularly human hair, are dyed using a composition containing as essential component 1-methoxy-2,5-diamino-4,6-dimethyl benzene in the presence of an oxidising agent, e.g. H2O2.  The composition may also contain other dyestuffs, thickening agents and/or surface active agent and preferably has a pH of 8-10.

Title: Improvements relating to gas turbine engines

Filed: 1958-06-05
Abstract: 834,178. Stuffing-box substitutes; gasturbines. GENERAL MOTORS CORPORATION. June 5, 1958 [June 24, 1957], No. 17990/58. Classes 110 (3) and 122 (5). [Also in Group XXXIV] The labyrinth seals 42, 44 and 43, 46 of a gas-turbine for preventing the escape of oil from, or entry of gas into the bearing 33 supporting the turbine shaft 28, are arranged opposite partition walls 73 and 32 which separate the turbine rotor 27 from the bearing. The parts 42, 43 of the labyrinth seals are formed integrally with a stationary member 40 mounted in a support plate 37 and co-operate with sealing ribs 44, 46 formed on a member 34 mounted for rotation with the shaft 28. The member 40 is sealed with the partition wall 32, which divides chamber 65 at high-gas pressure from a chamber 66 at lower-gap pressure, by a ring 63 and, with the partition wall 73, which divides the chamber 66 from atmosphere, by a ring 69 engaging a ring 72 secured to the wall 73. A resilient ring 39 is mounted between the bearing housing 41, formed integrally with the member 40, and the support plate 37 to permit limited radial movement of the shaft and seals. In operation, any gas in the chamber 65 which leaks past the labyrinth seal 43, 46 escapes via a number of ports 67 into the chamber 66 and through a port or ports 68 to atmosphere. By suitably dimensioning the ports 68 the pressure in the chamber 66 is maintained slightly above atmospheric pressure so that a positive leak is maintained into a chamber 83 via a space 81 and ports 82, thereby preventing oil fed by a nozzle 59 into the bearing 33 from leaking into the main gas stream ; a baffle 76 is provided in the member 40 between the labyrinth seal 42, 44 and the bearing so as to direct most of the oil back to a sump 80 through passages 77, 78, 79. The labyrinth seals and bearing are cooled by directing cooler air surrounding combustion liners 19 leading to the turbine nozzle 23 on to the seals by a baffle plate 87, the air passing from the surrounding space through ports 89 and slots 91; the air also serves to cool the rotor 27.

Abstract: 882,999. Trueing grinding wheels. JONES & SHIPMAN Ltd., A. A., and HOULDSWORTH, J. July 22, 1959 [June 9, 1958], No. 18340/58. Class 60. A device for the diamond trueing of grinding wheels comprises means which imparts a bodily translatory movement to a diamond holder 9 so as to traverse the diamond 2 along on arcuate or sunstantially arcuate path generally conforming to the contour to be trued on the wheel and substantially parallel to the latter, and incorporates a follower 6 and a former or template 17 adapted to move the tool transversely of this path during its lateral movement. Fig. 7 shows in elemental form the principle involved, the wheel 4 having a profile comprising angled, straight and arcuate portions. The tool holder 9 is traversed along an arcuate guide 16 and is also capable of axial movement to permit the follower 6 to contact the template 17 which has a contour similar to the wheel profile but is of greater length than the path traced by the tool tip. In a preferred arrangement, Fig. 8 the tool-holder 9 is carried between two parallel motion links 23 which are attached at their opposite ends to a forked arm 25 rotable by a handle 30 about a fixed point 26. A similar forked member 28 pivoted at 29 is attached to intermediately located lugs 27 on the links 23, thus providing for an arcuate motion of the tool holder and traversing the tip along the arc 14, the axial displacement of which is effected by a fixed former surface 17. A modification, Fig. 9, provides for the location of the former and follower remote from the dust and debris of the trueing zone. In this embodiment, the tool-holder is not slidable relative to the link-motion but is mounted with the links and pivoted forked members on a block 31 which is slidable in rigid guides 32 in the direction of the centre-line of the wheel 4. The forked member 25 is branched at its lower end to support the former bar 33, movable by handle 30 in contact with a fixed stop 35. Specification 716,580 is referred to.
