Abstract: 465,196. Forging &c. metals. SHEARMAN, C. H. HOWLAND-. July 27,1935, No. 21346. [Class 83 (iv)] In working substances, such as steel, an intense pressure is applied with the tool from the commencement of the operation in contact with the work, the pressure being applied at a low initial velocity increasing smoothly by infinitely small increments throughout the working stroke. The pressure correspondingly decreases. A parabolic relation exists between the velocity and tool travel. The work is clamped around a hole to be punched before the intense pressure is applied. A linkage is diagrammatically shown in Fig. 12 for carrying out the operation. The work 14 is pressed upwards from below by a rest plate 171 before the commencement of the working stroke, a clamping element 30 bearing on the upper face and transmitting compression stress to a spring 32 working against a cage 33 pivotally connected to a tool beam 39 mounted on an anchored pivot 41. A pair of toggle links 34, 35 couple the tool beam to an anchored pivot 37 and are connected by a link 51 to a link 49 on which is pivoted a toggle link 42. The latter is pivoted at 44 to a second toggle link 43 pivotally anchored at 52. A rotating crank disc 46 transmits motion to a link 45, connected by a link 57 to a sector 55 gearing with a sector 54 pivoted at 52. The toggle links 34, 35 in line correspond to the commencement of the operation at which the pressure is greatest, the lost motion having been taken up as well as the clamping of the work having been taken up previously by an upward movement of the rest plate 171.

Title: An improved electrically heated tunnel furnace
IPC: F27B9/06
Filed: 1949-08-19
Abstract: 663,996. Electric tunnel furnaces. AKT.- GES. BROWN, BOVERI, & CIE. Aug. 19, 1949 [Sept. 4, 1948], No. 21590/49. Class 39(iii) In an electric tunnel furnace operating on a three-phase supply and having electric heating elements in the roof and on trucks for transporting the material to be heated, the roof heating zone is divided into firing sections and the heating elements of each section are arranged to form the phases of a delta arrangement, the associated truck heating elements in each section forming the third phase of the delta arrangement. The width of the furnace is preferably greater than its height. The wiring diagram shows two heating sections a, b of a preferred arrangement. At each section, when the temperature rises above a prescribed value, the power of the roof heating elements 2 is first reduced by the opening of a switch, controlled by a relay 5 whilst the truck heating is not reduced, and when a higher temperature is exceeded the entire roof and truck heating is switched out by the opening of a switch by a relay 4. According to a modification, at this higher temperature only the truck heating is entirely switched out whilst the roof heating is left at half its initial value, the heating elements in the roof being switched out at a third regulating step. As each truck reaches a fresh heating section, a control element 9, mechanically actuated by the trucks, interrupts the current supply to the truck elements 3 for a short time by engagement with a contact 7 controlling a relay 6. When leaving a section, the current is similarly interrupted by a contact 8 controlling the relay 6. According to some modifications, the truck heating may be switched on either automatically or manually before the roof heating zone of the furnace is reached and if desired the roof heating and truck heating can each be separately regulated. In a simple construction, all the truck heating elements that are in the roof heating zone of the furnace are switched in and out simultaneously.

Abstract: 465,649. Controlling internal-combustion engine electric power units. SULZER FRERES SOC. ANON. Aug. 5, 1936, No. 21606. Convention date, Aug. 12, 1935. [Class 135] [Also in Groups XXVI and XXXV] A power unit comprising an internal-combustion engine driving a main electric generator from which current is supplied for example to the traction motors of a vehicle and provided with a speed governor adapted on the one hand to regulate the fuel feed pumps and on the other to actuate the control valve of a servomotor operating a rheostat in the excitation circuit of the main generator, is fitted with an adjustable limitation device for determining, at will, the maximum value to which the fuel supply can be increased. In the form shown in Fig. 2 the movable sleeve 9 of the centrifugal governor 34 is coupled by a lever 10<1> and spring link 19-21 to a rack 22 adapted to rotate pinions splined to the plungers of the fuel feed pump 23. The sleeve is also coupled by a second lever 10 and lever 13 to the control valve 14 of a servomotor 15 adapted to operate the movable arm 18 of a rheostat 5 in circuit with a separate exciter and part of the field circuit of the main generator. To limit the movement of the rack 22 a hinged stop 27 is provided. This stop is normally held against a fixed pin 29 by a spring, but is moved into one of two other positions nearer the rack when one or both of two solenoids 30, 31 are energized consequent on movement of the drum switch 46. The governor is loaded by three springs successively brought into operation by admitting compressed air through solenoid actuated cocks 40, 41, to the spaces above a pair of telescoping pistons. These solenoids are controlled bv further contacts on the drum switch. With the drum shown there is one fuel setting for each speed setting, but a modification is described giving two fuel settings for each speed setting. In a modification the spindle of the control valve is arranged in line with the pump control rack. In this form the variable loading of the governor is dispensed with. The stop may be controlled through mechanical, electrical or hydraulic means and may be influenced in accordance with the pressure temperature or humidity of the atmosphere or in accordance with two or more of these conditions simultaneously. The switch 46 may be provided with a locking device whereby the whole of the resistance 5 may be made effective as long as the switch is in its zero position. This device may comprise a double change-over cock inserted in the supply conduit 16 and in the discharge conduit 17<1>, whereby fluid may be admitted through the conduit 171 and discharge through the conduit 16 and so move the piston 15 to the extreme right-hand end of the cylinder. Specification 379,882, [Group XXVI], is referred to.
