Title: Hydraulic drive vehicles
IPC: E02F9/22
Filed: 1966-02-11
Abstract: 1,140,503. Hydrostatic gear control. INTERNATIONAL HARVESTER CO. 11 Feb., 1966 [8 March, 1965], No. 6076/66. Heading F2D. Traction wheels 12 of a front-loading tractor are driven by at least one hydraulic motor 62, Fig. 1, supplied from a pressure conduit 30 through a relief valve 122, Fig. 2, loaded by a spring 124, the compression of which is variably controlled by a slidable abutment piston 134, loaded by fluid-pressure in a chamber 146 controlled by a graduated exhaust valve 158, Figs. 1 and 3 (not shown), operated by a pedal 130. The pressure-conduit 30 is fed by a lowvolume, high-pressure pump 24, Fig. 1, a high volume low-pressure pump 26, for feeding load-handling rams 18, 20, being additionally available to supply the traction motor 62 under control of a selector valve 50, Figs. 1 and 2, which reverses the direction of flow 60, 70 to or from the motor and provides, in addition to neutral, two forward and two reverse settings, one in each case using the high-pressure pump 24 alone, the other using both pumps 24, 26 together. The variably loaded relief valve 122 is in the feed conduit 30 from the high-pressure pump 24 only, and fluid pressure in its loading chamber 146 is derived from the supply conduit 30 through a restrictor 154, Fig. 1, and conduit 144 branched to the pedal-controlled graduating exhaust valve 158, detailed in Fig. 3 (not shown). Adjusting shims 138, at the spring-base, provide pressure adjustment in 10 p.s.i. increments, and control pressure in the chamber 146 is limited to 800 p.s.i. by a spring-loaded valve 150. The pedal-controlled exhaust valve 158 provides for pressure relief by the valve 122 over a range of zero to 2500 p.s.i., by varying chamber-pressure 146 from zero to 800 p.s.i. The low-pressure pump 26 feeds the selector valve 50 through a conduit 46, including a simple relief valve 114 which is also opened, to unload the pump, when pressure in the highpressure conduit 30 reaches 600 p.s.i., and acts on a piston 120 on the relief valve 114, through a spring-loaded check valve 118. Cheek valves 108, 110 prevent cavitation in the motor 62, and exhaust 52 from the relief and selector valves passes through a cooler 54 to a reservoir 66. Both pumps 24, 26 are driven by a constantspeed electric motor 22 energized by overhead cable.

Title: Improved means of making blanks for sound recording and apparatus therefor
IPC: B29D17/00
Filed: 1933-03-03
Abstract: 415,797. Sound - record blanks. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.- (Assignees of Patterson, E. M. ; 293, South Center Street, Orange, and Shaw, A. D. ; 5th Street, National Park, both in New Jersey, U.S.A.) March 3, 1933, No. 6581. Convention date, Oct. 29, 1932. [Class 40 (ii).] A method of forming a blank for sound recording consists in forming a thin layer of molten wax on a rigid disc, cooling the wax to a temperature at which the slope of the cooling curve of the wax abruptly changes (this temperature having been previously ascertained), maintaining the wax at this temperature until a ripple occurs on the surface of the wax and traverses it entirely, and then cooling the wax to room temperature. The invention is based on the observation that when a ripple has been produced in this manner, the surface is left very even. The effect is best produced by using a cooling system of spiral type, by which the wax is cooled from the centre outwardly. Bleached montan wax containing lead stearate is suitable. The Figure shows an apparatus for carrying out the invention, comprising a metal plate 11 in which is a spiral channel 12 having an inlet 13 and an outlet 14. The plate 11 serves to support a recessed metal disc (not shown) on which a layer of wax for forming the blank is provided. Steam and water supply pipes 16, 17 are arranged as shown, 18 being a steam trap, 20 a byepass therefor, and 21 a main byepass. Valves 22-25 are placed so as to control the flow of steam or water as necessary, and a pressure gauge is used to enable the temperature to be judged by indicating the steam pressure in the spiral channel. A vertical mirror 32, illuminated by a lamp 27 is mounted behind the plate 11, the mirror having a regular pattern on its surface, formed for example as intersecting oblique lines. By observing the reflection of the pattern in the molten wax surface, the operator is enabled to see the formation of the ripple and its progress across the surface. Specification 388,431 is referred to.
