Abstract: 226,476. Cantilever Wrench Co., (Assignees of Carnelli, F. J., and Morris, R. B.). Dec. 17, 1923, [Convention date]. Chain wrenches.-In a chain pipe wrench one end of the chain is adjustably connected by screw means to one side of a housing in which is mounted a gripping jaw and an operating camhead on the end of the wrench handle, the other side of the housing having means for the attachment of the chain. The housing 3, Fig. 4, is provided on one side with a lug 5 to receive a bolt 14 to which one end of the chain 6 is attached, and on the other side with hooks to engage the projecting link pins 8. The jaw 9 is loosely retained in the housing by means of pins 13 engaging large openings 12 in the sides of the jaw, and the jaw is recessed centrally to provide two spaced gripping surfaces 11, Fig. 5, the walls 10 of the recess sloping away from the surfaces 11 so as to accommodate the chain 6 when the wrench is used on pipes of very small diameter. The cam head 2 of the handle 1 is adapted to bear against the back of the jaw 9 and also against ledges 4 in the housing. In using the wrench any lost motion of the handle may be taken up by placing the handle in its middle position and turning the nut 15 on the bolt 14 until the chain tightly grips the pipe. Specification 211,136 is referred to.

Title: Improved Electro Pneumatic Brake System.
Inventor: TURNER WALTER VICTOR
IPC: B60T13/66
Filed: 1917-06-26
Abstract: 111,439. Turner, W. V. Dec. 6, 1916, [Convention date]. Fluid - pressure. - Electropneumatic brakes for railway or tramway vehicles, of the kind in which pneumatically independent braking-unite are provided on the various vehicles and controlled entirely by electric means and in which the brakes are automatically applied when the circuit is broken, are provided with two electro-magnetic application valves, one effecting a service application of the brakes when energized, and the other effecting the automatic application when de-energized by failure of the circuit. In the form shown, magnets 2, 4, G control respectively a service application valve 3, a release valve 5, and a second or emergency application valve 7, connected as shown to the reservoir 8 and brake cylinder 11, the magnets being controlled by drivers' switches and circuits as shown. The train wires 18, 20 are connected together at the rear of the train, as are also the wires 15, 21. For release, the switch is placed iu the position shown at the left-hand side of the Figure, in which a contact 23 connects wires 20, 16, thus energizing the magnet 6 by the circuit comprising battery 19, wires 18, 20, contact 23, wire 16, magnet 6, and wire 17, and causing the valve 7 to engage its lower seat so as to open the brake cylinder to atmosphere by way of passage 13, valve 5, passage 25, valve 7, and exhaust 26. In the service position of the switch, the contact 24 connects wires 14, 15, 16, and the contact 23 connects wires 20, 21, whereupon the magnets 2, 4 also are energized, thus closing valve 5 and opening valve 3, past which fluid flows from reservoir 8 and passage 10 to passages 13 and brake cylinder. The switch may be then turned to lap position, in which wire 14 only is disconnected, thus closing the valve 3. If the circuit fails due to a break in the train, all the magnets are deenergized, whereupon the valve 7 is raised to its upper seat, cutting off brake cylinder from exhaust 26 and connecting it to the reservoir past a check valve 27. The valve 7 may be thus raised to its upper seat by manual operation of the switch to a position which disconnects all the wires. Loss of brake pressure during a service application, owing to opening of the valve 5 due to failure of the release circuit, is prevented by de-energization of the magnet 6 owing to the connexion between the wires 15. 16 provided in the service and lap positions of the switch.

Title: Apparatus for and a method of testing viscoelastic solids
IPC: G01N3/34
Filed: 1976-03-09
Abstract: 1532033 Measuring visco-elastic properties electrically ALLIED CHEMICAL CORP 9 March 1976 [10 April 1975] 09402/76 Heading G1N Visco-elastic solids are tested by holding the solid under tension, applying a cyclic displacement thereto and transforming the mechanical motion into an electrical signal. A tyre cord 4 is tested by tying it in a loop and supporting it by two wires 30, 32 in a chamber 22, the temperature of which can be controlled. The wire 32 is connected to a device 8 for applying a constant tension to the cord 4 and including a movable member 40 mounted by means of a lead screw on a stationary member fixed to platform 48, the constant tension being maintained by a servomotor 44 and the leadscrew. Mechanical stress developed in the cord 4 during testing is converted to a stress signal by transducer 14 and creep of the cord is monitored by a mechanical scale and pointer device 24 and/or a transducer 20. Wire 30 is connected to a displacement generator 10 including an eccentric drive 50 so that sinusoidal displacement is applied to the wire 30 whereby sinusoidal strain is applied to cord 4. The amount of strain applied to wire 30 is monitored by transducer 16 and an electrical differentiated strain signal corresponding to a mathematical differentiation of the strain signal from transducer 16 is obtained by transducer 18 indirectly coupled to the displacement generator 10 by a differentiating spring and wire. Circuitry, Fig. 4. The strain signal γ from transducer 16 is fed via amplifier 93 to the horizontal plates of oscilloscope 86 to the vertical plates of which are applied the stress signals # from transducer 14 so as to produce a hysteresis loop, Fig. 6 (not shown), the area of which is proportional to the energy dissipated by the material 4 during one cycle of testing and may be determined by mechanical means using a photograph of the oscilloscope trace. Alternatively the area may be determined electrically using integrating means 28 wherein the differentiated strain signal # from transducer 18 is multiplied at 100 with the stress signal # and the product integrated at 102. The resultant area signal is displayed on digital voltmeter 104. In addition the stress signal # and/or differentiated strain signal # may be fed to a peak finder 106 which measures the peak to peak voltages #V#, #Vγ and which may be displayed on meter 104. The complex modulus E may be obtained by obtaining the ratio #V#/#Vγ. The stress signal # is also applied to the pre-tension control 108 which controls the servomotor 44. Details of the various parts of the apparatus are given. A block of material such as rubber may be tested for its ability to withstand fatigue by clamping the material to the wires 30, 32, Fig. 12 (not shown). Alternatively a material may be tested for shear, Fig. 13 (not shown), and compression, Figs. 14 and 15 (not shown).

Title: Combined stereotype matrix former and drier
IPC: B41D1/00
Filed: 1930-03-25
Abstract: 348,307. Stereotype matrices. COCHRAN, A. W., 6724, Hollywood Boulevard, Los Angeles, and DEWEY, H. W., 304, Benton Street, Portland, Oregon, both in U.S.A. March 25, 1930, No. 9529. [Class 100 (ii).] A stereotype matrix is dried and prevented from warping by holding it firmly by a vacuum or pneumatic pressure against a surface and holding the margins by aesilient mechanical pressure, heat being applied while the matrix is thus held. The device comprises an oven-like body formed of semicircular side-plates c and a curved cover 2 carried on a support 3. A hollow shaft is adjustably mounted in the plates c so as to be movable towards and from the cover, and carries radial elements f supporting electric heating elements g and reflecting surfaces l. The cover is pivoted on a shaft 4 on the support 3 and fits closely between the plates c. The shaft carries operating levers 5 parallel to the plates c, and connected together at their free ends bv a bar 6 slidable in slots in the levers and attached to catches 7 adapted to engage projections 8 on the cover. An arm 20 on the shaft 4 carries a roller adapted to engage an arm 21b on a rock shaft 21 supported by bearings 21a on the frame. A second arm 22 on the shaft 21 is positioned to engage a roller j<1> on a rod to which arms i are pivotally connected. The rod is guided for vertical movement only. The arms i are pivoted to arms h, h<2> extending along the curved and straight edges of the cover and carrying coil springs k for holding the matrix against the cover. The cover is hollow, and its inner face is perforated, the hollow part being connected by flexible pipes 27 to a vacuum pump 29. In use, one edge of the matrix is placed under clips on the cover, and the vacuum draws the matrix into close contact with the cover. The cover, which has been resting in open position on a support 36, is then closed by the handle 6, which can continue to move after the cover is closed, the sliding of the handle relative to the levers 5 permitting the release of the catches 7. The shaft 4 therefore rocks the arm 20, and, through the parts 21b, 21, 22, j<1>, raises the rod j and arms i to lift the arms h, which are formed in two sections pivoted together at h<1>. The springs k therefore hold the matrix against the cover. Continued rotation of the shaft 4 causes an arm to engage a switch-plate 31a and move it, against the action of a spring-pressed button, to close the switch 31 of the circuit of the heating elements g. After the matrix is dry, the handle 6 is raised, to open the switch 31, lower the arms h and release the matrix, and finally raise the cover. The springs k are normally of sufficient tension to permit them to give and allow the matrix to shrink. The springs k may be replaced by pads of steel wool which may be wired into place on the arms h. In a modification, the matrix is adapted to be pressed against the cover by air under pressure in a sealed con. tainer, the cover being perforated to permit the escape of the generated steam. The device can also be adapted for heating by gas.

Title: Improvements in preparation of cellulose esters having a high content of propionyl or butyryl
IPC: C08B3/08
Filed: 1937-04-03
Abstract: Cellulose simple or mixed esters containing a large proportion of propionyl or butyryl groups are obtained by pretreating cellulose material with a liquid containing a large proportion of propionic or butyric acid and in the presence of 5-20 per cent of water based on the weight of the cellulose in addition to the water inherently present in the cellulose and in the absence of catalyst, then adding excess of acyl anhydride so as to react with the water before the start of the esterification reaction, cooling the mixture to dissipate the heat of reaction, and then adding catalyst and further anhydride and allowing esterification to proceed.  Part of the catalyst may be added to the pretreated cellulose with the first portion of acyl anhydride.  For the pretreatment step, the water required may be added to the treatment liquid or the cellulose may be exposed to humid air or wet steam.  In an example, cotton linters containing 2 per cent of moisture are pretreated at raised temperature with propionic acid containing water in a proportion of 20 per cent based on the weight of the cotton.  Propionic anhydride is added and the mass is cooled.  A mixture of propionic acid, propionic anhydride, and sulphuric acid is cooled and a small part of it is added to the pretreated cellulose mass.  After all the water present has combined with the anhydride, the mass is again cooled and the rest of the catalyst mixture is added.  The cellulose ester produced is precipitated from the solution by pouring into water or methyl alcohol.  Solutions of the product form clear flexible films. The Specification as open to inspection under Sect. 91 comprises also pretreatments in which the proportion of water added exceeds 20 per cent and may be as high as 50 per cent based on the weight of cellulose.  This subject-matter does not appear in the Specification as accepted.
