Abstract: 550,601. Grinding. NORTON CO. Oct. 10, 1941, No. 13097. Convention date, Oct. 26, 1940. [Class 60] In a grinding-machine comprising a rotary and axially movable work-support and a transversely movable wheel-slide, a hydraulic motor for the wheel-slide feed-device is provided with a reversing-valve having two pilot-valves, which are operated by the motor and the worksupport, selection of one pilot-valve or the other by a selector-valve causing the motor to effect a continuous or intermittent feed. In the arrangement shown in Figs. 3 and 4, a feed-pawl for the lead-screw of the wheelslide is operated by an adjustable crank 76 on a shaft 74 driven by a hydraulic motor comprising a chamber 86, and a vane 93 on the shaft. The motor is in circuit with a reversing-valve 97, pilot-valves 110, 111, and a rotary selectorvalve 105' which is geared to a setting-knob. The valve 110 is connected to a slide 118 having a finger 117 in the path of a pair of arms 123 on the shaft 74. The valve 111 is connected by a link 145 to a lever in the path of dogs on the work-support. To produce continuous feed of the wheel-slide, the valve 105 is set in the position shown, Liquid supplied by a pump 40 then passes through the valve 104 and around the valves 110, 97, and the motor moves counterclockwise, until the valve 110 is thrown over by one of the arms 123. Thereupon, the reversing-valve. 97 is thrown over and the motor moves clockwise until the other arm 123 returns the valve 110. To produce intermittent feed of the wheel-slide, the valve 105 is turned through a right-angle. Liquid then flows around the valves 111, 97, and these are thrown over at the ends of the stroke of the work-support. The valve 105 is employed also as a throttle-valve for adjusting the speed of the motor. Specifications 6784/01, [Class 60], and 463,334 are referred to.

As shown, a generating chamber 1 is supplied with carbide through a shoot 2 which delivers it to a grid 4.  A baffle 4 is arranged at the side of the grid 4 between the grid and an outlet 10 for water and sludge. The baffle 5 is normally completely submerged in the water, which is supplied through a pipe 6 arranged along the lower edge of the baffle and having perforations which direct the water under the baffle towards the grid.  The discharge pipe 10 opens into a tapering chamber 11 extending at its top across nearly the whole width of the generating chamber and provided with a grid 14 to retain lumps of carbide.  Circulation of the water as shown by the arrows is assisted by a plate 19 and one or more transverse baffles 20.  The gas leaves the generator through an outlet 16.

Filed: 1929-04-30
Abstract: 310,812. Research Corporation, (Assignees of Fiedler, M.). April 30, 1928, [Convention date]. Coating; coating by dipping.-A metal body 'having a coating of another metal is heated by induction of a high frequency current to cause diffusion of the metals at the junction. In an example, a steel tube of 1 inch diameter and 1-16th inch thickness having a chromium coating of the thickness 0.0002 inch is passed through a coil 5¢ inches long and 1# inches in diameter having a power input of 22-23 kw. at 30,000 cycles at a rate of 0.4-0.55 inch per second. The heating current in the tube is localized by skin effect. A higher power input is necessary at lower frequencies. The coating may be carried out by electrodeposition, cold forging, dipping, spraying or painting. The heating may be carried out in air, in vacuo or in a reducing or neutral gas. Chromium plate on heating gives off sufficient hydrogen to form a neutral atmosphere. Iron may be coated first with chromium and then with cobalt before heating. A zinc base may be coated first with bismuth or cadmium and then with copper. Plates or irregularly shaped articles may be treated by the use of a flat spiral or other appropriately shaped inducing coil. The heating may be followed by a heat treatment in an ordinary furnace. According to the Specification as open to inspection under Sect. 91 (3) (a), a rapidly interrupted direct current may be used as inducing current and the invention may be applied to the case hardening of iron or steel by heating in a carburizing gas or to decarburization. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 275,233.

Title: Curing agents for epoxide resins
Inventor: COLLINSON HAROLD ARTHUR
IPC: C08G59/18
Filed: 1955-05-10
Abstract: Secondary curing agents for epoxide resins are obtained by reacting a secondary monoamine having its N atom linked to two different carbon atoms with a glycidyl ether of a polyhydric phenol having at least 3 OH groups.  At least 1.5 mols. of amine are used per epoxy group in the glycidyl ether and unreacted amine is removed.  In the example diethylamine (3 mols.) was added to a solution in dioxane of a glycidyl ether of a low molecular weight phenol-formaldehyde condensate (equivalent to 1 epoxy group). Dioxane and excess amine were removed after reaction leaving a viscous liquid, 35 parts of which were equivalent for curing epoxide resins to 10 parts of diethylamine.  Dimethylamine and piperidine are suitable amines and the glycidyl ether of 1,3,5-trihydroxy benzene is also suitable as a starting material. Specifications 691,543 and 705,786 are referred to.ALSO:Secondary curing agents for epoxide resins of the kind described in Specifications 691,543 and 705,786 are obtained by reacting a secondary monoamine having its N atom linked to two different C atoms with a glycidyl ether of a polyhydric phenol having at least three OH groups.  At least 1.5 mols. of amine are used for each epoxy group in the glycidyl ether.  Examples of suitable glycidyl ethers are (A) a mixture of 12.6 parts 1,3,5-trihydroxy benzene and 55.5 parts epichlorhydrin were reacted by dropwise addition of 120 parts NaOH in an equal weight of water, the temperature being maintained at 60 DEG  C.  A viscous resin was obtained by separating the organic phase from the inorganic and washing it free from NaCl.  (B) 376 parts phenol were reacted with 83 parts formaldehyde using 154 parts boron p  trifluoride-ethyl etherate complex as catalyst.  263 parts of the condensate were reacted with 365 parts epichlorhydrin in presence of 252 parts 50% NaOH.  In preparing the secondary curing agent 220 parts diethylamine were reacted with 200 parts Resin B in 200 parts dioxan, there being 3 mols. amine present per epoxide group.  The mixture was reacted at 60-70 DEG  C. for 3 hours after which excess amine was removed under vacuum.  A viscous resin was obtained.  For the curing of epoxide resins, 35 parts of this product were equivalent to 10 parts free diethylamine.  Other suitable amines mentioned are dimethylamine and piperidine.

Abstract: 868,359. Polarimeters. BOR, J. July 27, 1959 [April 29, 1958], No. 13602/58. Class 40(3) In a polarimeter the extinction angle is determined as the mean of two angular settings at which the brightness is equal to a standard. A beam splitter 3, Fig. 1, directs about one-fifth of a beam 4 via path 6 to a photo-cell 9, the remainder passing through the polarimeter 1, 2, to a photo-cell 8. When the light intensity falling on the two cells is the same an electrometer 10 in a bridge circuit, Fig. 3, indicates zero. Coarse setting of the zero of the electrometer is effected by resistor 22 and fine adjustment by resistors 23, 24. Sensitivity is controlled by the circuit comprising battery 25 and resistors 26, 27 and the photo-cell dark current is compensated by the circuit comprising battery 15 and resistors 16, 17, 18, 19 and 20. The electrometer needle may be earthed through resistor 28. In one modification the two beams may be alternately directed on to one photo-cell and the output adjusted to be steady and in another, Fig. 4 (not shown) photo-conductive and photovoltaic cells are used. The beam splitter and photo-cells may be arranged in units for attachment to a standard polarimeter.
