Title: Adjustable platen power presses
IPC: B30B15/00
Filed: 1930-04-26
Abstract: 350,156. Power presses. BLISS CO., E. W., 2nd Avenue, Brooklyn, New York, U.S.A.- (Assignees of Strout, R. W.; 141, East 21st Street, Brooklyn, New York, U.S.A.) April 26, 1930, No. 12928. Convention date, May 3, 1929. [Class 100 (ii).] Embossing and stamping. - A power embossing or stamping press, which is especially applicable for acting on blanks which require a large clearance between the platen and the die, is constructed with a platen 9 which is movable on guideways 8 independently of a crosshead 7 to which the platen is adjustably connected by means of screws 10 and nuts 17 which are mounted in the crosshead with capacity of rotation but with restraint against axial motion. The crosshead is also controlled by the guideways 8, and is reciprocated by a pair of connecting-rods 6 from a crank shaft 4. To adjust the platen 9 relatively to the crosshead, the screws 10 are moved axially by simultaneously rotating the nuts 17 by means of worms 21 on shafts 22 geared together and connected by spur gears 30, 31 to the shaft of an electric motor 35 which is mounted on the crosshead 7. The worms 21 engage worm wheels 20 formed integrally with the nuts 17. When the screws 10 are raised to their highest position, so as to leave the maximum space between the platen 9 and the bed 3 for the die, the ends of the screws extend above the crank shaft 4. The platen 9 is preferably formed as a rigid casting having a lower platen face 46, a central rib 47, an upper truss plate 48 and transverse end ribs 49 formed with projections moving in the guideways 8. Transverse ribs 50 are also formed in alignment with the screws 10, and a central rib 51 also assists to strengthen the parts 46, 47, 48.

Title: Speed indicator and regulator
IPC: G01P3/18
Filed: 1930-04-26
Abstract: 354,180. Centrifugal governors. SALOMON, F. M. M. B., 130, Boulevard Brune, Paris. April 26, 1930, No. 12948. Convention date, Nov. 26, 1929. [Class 57.] The rotating shaft 1, the speed of which is to be controlled, has secured to it a cage 2 containing balls 3 which, under the action of centrifugal forces, press against the interior surface of the hornshaped body 4, fixed to the spindle 5, carried in bearings 6, causing it to rotate against the action of a spring 7 until a position of equilibrium is reached, the moving body 4 actuating through the links 19, 20, 21 a shutter 22 controlling the flow of a fluid such as steam feeding a cylinder of a steam engine whereby the speed of the shaft 1 is caused to return to its normal value. The cage 2 can be made with guides 14, 15 for the balls 3 at equal angular distances apart so as to keep the device balanced. The body 4 is made with a recess 16 to prevent the shaft 1 from fouling the body 4. The surface of the body 4 is made with projections 17 on either side of the recess 16 tangential to the path of the ball as it passes over the recess 16 in order to avoid jerky motion and is made with a depression 18 opposite the recess 16 to keep the device balanced when a ball is passing over the recess. The surface of the body 4 is shaped so that its angular displacement is connected with the speed of the shaft 1 by a predetermined law and formulae for calculating the shape of the body 4 are given. The balls may be replaced by rollers &c. In a modification the body 4 may be fixed and the shaft 1 driven through a yielding shaft and rotatable about the spindle 5.

Title: Improvements in or relating to telegraphic wireless and similar signalling systems
IPC: H04L27/04
Filed: 1930-04-29
Abstract: 348,858. Code telegraphy ; wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Finch, J. L. ; Port Jefferson, Long Island, New York, U.S.A.) April 29, 1930, No. 13179. Convention date, May 21, 1929. [Classes 40 (iii) and 40 (v).] Relates to a tone-keying system in which signals comprising trains of audio-frequency waves are transmitted from station A over line 6 to a relay station B, where they are converted into D.C. impulses of rectangular wave form and either modulate the radiation of a wireless transmitter C or are retransmitted over a line. Impulses of form a pass from a generator 2 through transmitter contacts 4 and line 6 to the relay station B, where they arrive in the distorted form b. They are rectified by the negatively biased pair of valves 10, 12 to the form c, so that d represents the voltage applied through potentiometer 20 to the grid of valve 18, which has a normally flowing plate current, while e represents the resulting conductance of that valve. The grid bias of valve 18 is such that the crests of the signals are cut off, while the waves are smoothed out by condenser 30, so that the plate current in resistance 28 is of the form f. The failure of current in this resistance on receipt of signals raises the voltage across the discharge device 32 above the striking voltage, whereupon current flows through this device and resistance 34 in such a direction as to apply to the grid of valve 36 a pulse of positive D. C. voltage with a sharp commencement, as at g. The plate current of this valve flowing through resistance 40 rises as at h, setting up a voltage drop which extinguishes as at i the current normally passing through the discharge devices 44 and resistance 46. The gridpotential of valve 48 consequently becomes more negative and cuts off as at j. The consequent fall of plate current in resistance 52 raises the plate current in valve 54, this cutting off that in valve 56 so that positive potential is applied to the plate of valve 68. When the tone intensity falls off the above operations are reversed, the sudden striking of discharge devices 44 giving a sharp termination 88 to the final wave form. To ensure the cutting off of the discharge current at 32 at the end of each signal, the condenser 92 is added. The striking of the discharge through 44 causes a surge of current from condenser 92 which extinguishes the discharge in 32. For back-stroke signalling the valve 56 may be omitted, or the switch 38 may be so set as to cut out valve 18 and discharge device 32. Thermionic modulation. The aerial 76 emits radiation derived from the oscillationgenerator 72 under control of a thermionic keying arrangement, by the effect of which current either flows or ceases to flow through resistance 106 in the plate circuit of valve 56. The absence or presence of potential drop along resistance 106 determines the presence or absence of sufficient plate voltage on valve 68 to enable emission to take place.

Patent GB-132816-A (GB)
IPC: G01C19/38
Abstract: 132,816. Carrie, F. G. Oct. 22, 1917. Gyroscopic compasses. - Means to compensate for errors due to friction between moving parts comprise ' microphonic ' contacts which are adapted to respond to minute changes in the relative positions of the parts between which the friction occurs. It is preferred to employ for mounting the gyroscopic compass disk a pendulous weight, associated with mechanism having gyroscopic wheels mounted thereon, as described and claimed in Specification 132,839. In the construction shown in elevation and plan respectively in Figs. 1 and 2, a frame 1 carries a gyroscopic disk 18 and also a second gyroscopic disk 29 by means of the frames 21, 26. The frame 1 is pivoted by shafts 2, 3 in hollow shafts 4, 5 by which a frame 6 is mounted in bearings upon standards 9 and 10. The means for reducing friction between the shafts 2, 3 and their bearings is shown in the end view, Fig. 4. Carbon contact buttons 40, 41 are carried by a fork 36 rigid with the hollow shaft 4 and co-operate with a contact arm 37 rigid with, but insulated from, the shaft 2. Movement of the shafts 2, 3 in their bearing causes pressure by the arm 37 upon one of the buttons 40, 41. The increased current thus produced in the corresponding circuit, including the battery 65, causes a deflexion of a galvanometer needle 74 to close the circuit of one or other of two electro-magnets 46, 47 and so bring into action means for slightly rotating a wheel 35 rigid with the hollow shaft 4 and reduce the pressure on the button. The wheel 35 is geared to a disk 53, which is made to rotate in the appropriate direction when the electro-magnet 46 is energized to bring down, by attraction of the armature 48, a wheel 52, mounted on a constantly-rotated jointed shaft 44, into contact with the disk 53; when the electro-magnet 47 is energized, the wheel 61 is drawn down into contact with the rotating wheel 52 and the wheel 35 so that the wheel 35 is rotated in the other direction. The standards 9, 10 are carried on a table 13, mercury floated in a trough 100 carried by a table 101, provided with ball sets 102 for the table 13 and resting on ball-bearings upon the frame 104, which is mounted in gimbals, and comprises the pendulous weight and gyroscope wheels previously referred to. Two rotary motors 117, 118 are provided for compensating friction that occurs owing to movements in azimuth. Co-operating contacts 141, 142, and 143, Fig. 6, carried by the trough 100 and table 13 respectively are employed to complete the circuit of one of the motors 117, 118 so that it rotates in the direction required to compensate for friction. Means are provided for adjusting the frame 1 so that the plane of the disk 18 may be inclined at an angle corresponding to the latitude.

Filed: 1932-05-12
Abstract: 393,409. Snap-action switches. BAGGS, H. G., Ordsal Electrical Works, Salford, Lancashire. May 12, 1932, No. 13656. [Class 38 (v).] A quick-break switch comprises a push-pull rod B having fixed to it an insulator E provided with a slot or slots in which moves a' U- shaped contact F. A rod K is fixed to the contact F and the other end of the rod is fixed to a plate H having slots through which the arms of the contact F project. This plate prevents the arms F from spreading apart too far under their own resiliency. A spiral spring L is arranged round the rod K and bears at its upper end against the insulator E. When the rod B is pulled to break contact, the friction grip between the contact F and the fixed contacts D, D\ holds the contact F stationary until the movement of the insulator E compresses the spring L sufficiently. The spring then acts to withdraw the contact F rapidly. In a modification the upper end of the spring L bears on a plate which itself bears on the insulator.
