Title: Improvements in or relating to speed sensitive mechanism for use in speed indicatingor controlling apparatus
IPC: G01P1/08
Filed: 1931-03-10
Abstract: 375,315. Centrifugal governors. SALOMON, F. M. M. B., 130, Boulevard Brune, Paris. March 10, 1931, No. 7432. Convention date, Dec. 12, 1930. [Class 57.] A speed regulator comprises a rotating shaft 1 rigidly carrying the four-armed bell 3 forming part of a surface of revolution 26, and slidably carrying the four-armed cage 4 for the balls 5, the cage carrying a pin engaging..-with a groove in shaft 1. The cage 4 is provided with inclined bearing surfaces for the balls and ends with a grooved ring 6 with which engages a stud 10 on an arm 9 of a weight 11 rockably mounted around an axis 8 on pivots 8a, 8b. The weight 11 neutralizes the gravitational effect of the masses of the members slidable along the shaft 1 for all positions of the mechanism, a method of designing it being given. The apparatus thus gives accurate regulation whatever its position in space, and when the apparatus is used on board a ship, aircraft, &c., the weight compensates for shocks, action of centrifugal forces in turning, &c. The shape of the surface 26 is preferably such. as to produce on the shaft 21 a torque substantially proportional to the speed, or the shape may be such as to give large rotations of the shaft 21 for any desired range of speeds. Instead of fixing the bell on the shaft and having the cage slidable, the cage may be fixed to the shaft and the bell may be slidable. Fig. 8 shows the main frame of the apparatus, made preferably by a pressure casting process, and comprising a main plate a, a wide limb b, and a narrow limb c extending at right-angles to the plate a and a cross-piece d between the two limbs carrying the bearing for the shaft 1. Fig. 9 shows diagrammatically the application of the invention to speed regulation by a cranked lever 52<1> pivoted at a and controlling a throttle 54. The Specification as open to inspection under Sect. 91 (3) (a) describes apparatus, Fig. 11 (Cancelled), in which a plurality of mechanisms described above control the rotation of the shaft 64 actuating the regulating, the shapes of the bells being determined so that one or several thereof have a preponderant action at a certain range of speeds. This subject-matter does not appear in the Specification as accepted.

IPC: B62D55/30
Filed: 1950-03-24
Abstract: 667,340. Endless track vehicles. INTERNATIONAL HARVESTER CO. March 24, 1950, No. 7441/50. Class 79(i) In an endless track assembly in which the idler wheel is loaded by a precompressed spring, the spring comprises a number of concave disc-like elements sc arranged that further compression thereof, e.g. when a stone is caught between the track and idler wheel, meets with decreasing resistance. As shown in Fig. 1 the endless track embraces the driving sprocket 12 whose bearings are fixed to the track frame 11, and the idler wheel 16 whose bearings are carried in a bracket 14 slidably mounted on the frame 11. Secured to bracket 14 is a rod 26 having abutments 32 and 33. Abutment 32 normally contacts the bracket 25 and limits outward movement of the idler wheel assembly, so that by suitably adjusting the screwed sleeve 44 carried by bracket 14 on the screwed portion 34 of rod 26, any desired amount of slackness may be left in the track under normal running conditions. Should a stone be trapped between the track and the idler wheels or drive sprocket, bracket 14 moves to the left and abutment 33 compresses the spring assembly 29 against cylinder 35 and fixed bracket 25. As shown in Fig. 2, the spring comprises pairs of oppositely opposed concave discs separated by annular spacers 39 and 41. Each disc preferably comprises a pair of like discs, e.g. 38, nested together whereby a damping action is provided by the relative sliding of the surfaces in contact. The spring assembly is enclosed in a casing 31.

Title: Improved method of manufacturing planar transistors
IPC: H01L23/544
Filed: 1965-02-23
Abstract: 1,080,177. Transistors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 23, 1965 [Feb. 24, 1964], No. 7673/65. Heading H1K. When making one or more double diffused planar transistors in a semi-conductor wafer a test structure is simultaneously formed in the wafer adjacent the transistors and consists of a region corresponding to the transistor base zone with a region corresponding to the emitter bridging this region to define a channel of the same thickness as the effective base zone of the transistors. The resistance of this channel, the length and width of which are known, is measured by a simple two-probe (Fig. 5, not shown) or four probe method to determine the thickness of the effective base zone. Several hundred transistors formed on a single wafer may each have an associated test structure, though normally many or all of the transistors are served by one test structure. Typically the base and corresponding zones 15, 13 (Fig. 1) are formed by diffusion of boron through oxide masking into an N-type layer epitaxially deposited on an N+ silicon wafer and the emitter and bridging zones 14, 25 by diffusion of phosphorus. Metal layers are then deposited through apertures in oxide masking to form electrodes for the transistor regions.

Abstract: 377,616. Roller mills. MIAG MœHLENBAU UND INDUSTRIE AKT.-GES., 41, Rosstrasse, Brunswick, Germany.- (Assignees of Moog, C.; 9, Cellerstrasse, Brunswick, Germany.) March 18, 1932, No. 8049. Convention date, April 4, 1931. [Class 59.] The pressure of the grinding rollers upon each other is controlled in accordance with the supply of material to be ground through a controlling device in the feed chute operating a servo-motor which supplies fluid pressure to hydraulic cylinders acting on one of the grinding rollers. A spring-supported member 17, Fig. 1, movable by the flow of feed to the mill, is connected by bell-cranks to a disc 27 forming a pressure member to a spring 28 loading a relief valve 29 in a chamber 30 supplied with liquid from a chamber 2 by a pump 10. A pipe 23 conveys the fluid pressure to cylinders 24, the pistons of which are connected to the bearings of the roll 36. When the flow of feed to the mill increases the member 17 descends and pressure on the spring 28 increased thereby increasing the pressure between the grinding rollers. In Fig. 2, the member 17 transmits movement to a needlevalve 13 seated in an orifice 12 in a piston 6 movable in a cylinder 8. The upper part of the piston is supplied with fluid by a pump 10 and the fluid is led off by a pipe 23 to cylinders 24, the pistons 25 of which transmits the pressure to the grinding rollers. The piston 6 is supported on one arm of a lever 5, the other arm supporting a rod 7 passing through a fixed part of the mill frame. A spring 4 surrounds the rod 7 and is adjusted by a ring 4<1> to balance the piston 6. The rod 7 may be extended to operate the feed valve 22. A known device may be connected with the servo-motor by which the grinding rollers are thrown out of action when the flow of grist stops and are brought into action again when the flow of grist is resumed. The pistons 25 may be fitted with relief valves in order to relieve the pressure in the cylinder when an unbreakable body passes through the rolls.

Abstract: 855,570. Electric measuring systems. KUHN, L. March 13, 1958 [May 13, 1957], No. 8113/58. Class 40 (1). [Also in Group XL (c)] Apparatus for calibrating a transducer measuring the pressure in an I.C. engine cylinder comprises piezo-crystal for measuring the pressure directly and a diaphragm subjected to the cylinder pressure and a known pressure to give an indication when the two are equal. The transducer 8 (Fig. 1), is mounted in the cylinder head 9 and comprises a piezo-crystal 1 subjected via a member 2 to the internal pressure p, and a metal diaphragm 3 subjected on the one face to the internal pressure p and on the other face to the calibrating pressure p1, so that when p#p1 the diaphragm 3 contacts a member 4 to produce a rectangular signal starting and finishing when p=p1 in each cycle. These rectangular signals, produced at 12 in Fig. 2, are amplified at 15 and differentiated separately at 16, 17 to give a short pulse at their start and finish. The pulses from 17 are superposed at 20 on a time base, voltage from generator 21 to give the waveform shown in Fig. 3, 3E, and fed to the horizontal plates 13h of a cathode-ray oscilloscope 13. The pulses from 16 are given a small time delay at 18 and superposed at 19 on the measuring signal from the piezo-crystal, developed at 11 and amplified at 14, to give the waveform shown in Fig. 3D, and fed to the vertical plates 13v of the cathode-ray oscilloscope 13. The cathode-ray oscilloscope thus produces the cyclic waveform 3F of Fig. 3. The pulses are emphasized on the cathode-ray oscilloscope screen by feeding on to the control grid rectangular pulses derived from a monostable circuit 22, controlled by the short pulses from differentiator 16.
