Title: Improvements in frictional power-transmitting units of the follow-up type
IPC: G05G19/00
Filed: 1937-12-10
Abstract: 507,164. Drilling - machines. ARMSTRONG, J. J. V. (Vickers, Inc.) Dec. 10, 1937, No. 34197. [Class 83 (iii)] [Also in Group XXIV] A frictional follow-up gear for an electric drill comprises differential wheels 16, 17, constantly driven by a motor 19 at the same speed in opposite directions, and formed with toric raceways frictionally contacted by planetary rollers 14, tiltably mounted on a carrier 9a integral with the driven shaft 9. In the neutral non-tilted position shown no movement is imparted to the driven shaft 9. Turning movement of a primary control such as a handle 1, tilts the rollers 14, causing the motor 19 to drive the shaft 9 in the appropriate direction until the handle is stopped; whereupon the shaft 9 restores the rollers to the neutral position and the drive is stopped. For this purpose, turning movement of the handle 1 rotates a differential-carrier 5, which fulcrums about an initially stationary side-wheel 8, fast on the driven shaft 9, and turns the other sidewheel 10, which is integral with a sleeve 10a, screw-threaded on a sleeve 11 splined to the driven shaft and having a groove engaging arms 12, integral with the pivotal carriers 13 of the friction rollers 14. The resulting axial movement of the screwed sleeve 11 tilts the rollers in one direction or the other, causing the motor 19 to impart a corresponding drive to the driven shaft 9, such drive persisting at the same speed as the handle 1 until movement of the latter is discontinued, whereupon the driven shaft 9 restores the rollers 14 to the non-tilted neutral position by reversing the movement of the threaded sleeve 11, through the differential-wheel 8, the now stationary carrier 5, the side-wheel 10 and 'the screwed sleeve 10a. To prevent overrunning of the driven shaft 9 a flywheel 22 is geared to the control handle 1.

Abstract: 1,066,028. Testing gauges. H. MEYER. Aug. 24, 1964 [Oct. 21, 1963], No. 34595/64. Heading G1M. In a device for ascertaining errors in an indicating device, a slidably mounted wedge block 5 is positioned beneath the plunger 8b of a dial indicator, and is operatively connected through a shaft 4 and gears 2, 3 to a motor 1. Gears 16-18 are also driven by the shaft 4 to rotate a housing 14 enclosing an objective 12 and mirrors. A prism 24 mounted in a tube 22 is rotated at half the speed of the housing 14 through gears 19-21. The image is focused on the screen 26 by a lens 25. In operation plunger 8b is displaced by the wedge 5 causing rotation of the pointer. The objective 12 is aligned with the tip of the pointer and rotates in synchronism with the pointer. Rotation of the image of the pointer is prevented by the reduction in speed of the prism. If the gauge shows no errors then the image 10a of the pointer appears to be stationary. To record the readings, the screen 26 is replaced by a moving strip of recording paper positioned across the path of the ray. A pair of slotted diaphragms may be provided to reduce the size of the image. A lever 29 on the shaft 4 mounts a photo-cell to scan the image ray, impulses from the cell being recorded on a strip 33.

[Also in Divisions B3 and G3]  A gear-hobbing machine comprises a grinding hob, memory means for registering the angular positions, and means for adjusting the phase relationship, of the gear and hob, and phase angle detector means for detecting the said relationship. The hob 10 is rotated by a motor 8 on a slide 5 fed by a screw 6 on a slide 2 fed by a fluid-pressure device 3. A pin 21 engages a disc on the work-mandrel 19 mounted with a work-rotating motor 15 on a slide 11 fed by a fluid-pressure device 12. The position of the hob is initially indicated by a pointer 28 aligned with an adjustable pointer 27 on the hob spindle. The work is meshed with the hob, by disengagement of a clutch and the use of a microscope 45, and a pointer 31 is adjusted along an arcuate slide to be in alignment with a lug 29 on a disc 30 on the workspindle. The device for registering the tool position is connected to a frequency-modulation capacitive displacement pick-up 37 connected to a two-phenomenon synchroscope 36 to produce a waveform 38A. The device for registering the work position is connected to a similar pick-up 39 to produce a square wave 40 which is fed consecutively to a differentiation circuit 41 and a rectifier circuit 44 so that one wave form 42A appears on the synchroscope. The synchroscope is employed in conjunction with a phase-shifter 35 to correct for backlash and errors in clutch-coupling &c. In one modification, the corrections are applied automatically, the phase-shifter being operated by a motor associated with a brake and, in another, three detectors are provided to detect lagging-, correct-, or leading-phase angles. In the latter case, the slide 5 is fed up to a stop 157 and is automatically withdrawn and re-advanced to permit phase adjustment when necessary. In a further modification, the disc 30, Fig. 10, has only one lug 29. The shaft of the motor 15 carries a pointer 334 which is associated with an adjustable pointer 335. A speedgoverning hand-brake or gear pump 337, Fig. 15, is provided in the drive to the work, the pump being associated with a control valve 349. The tool is connected directly to the shaft of the motor 8. In operation, the pointer 335 is adjusted until the pulse 344 coincides with the pulse 42 from the pointer 31. A switch 347 is then moved so that the pulse 38 from the tool pointer 28 shows on the screen.

Abstract: 1,112,260. Self-propelled missiles. ATLANTIC RESEARCH CORPORATION. 4 Aug., 1966 [25 Aug., 1965], No. 34959/66. Heading F3A. The rocket (10), Fig. 1 (not shown), after the ejection of a payload particularly meteorological equipment with a parachute housed in section (44), is fragmented into small pieces. Burning of the propellant grain 28 ignites a gas generator 70 which expands the end of a capsule 72 to move a rod 74. This releases a timer 62 which through a cam (98). Fig. 3 (not shown), and detent (108) releases a striker (102). A primer (110) ignites a gas generator (not shown) to eject the equipment. Later a second cam (116) similarly through an igniter (122) starts booster charges 82 which ignite a primary charge 48. This charge fragments heavier parts such as a head 30. A secondary charge 50 extending the full length of the casing in the form of a layer underneath a tail fin assembly 16, is ignited sympathetically and fragments the remaining parts. Fragmentation may alternatively be initiated by radio link (162), Fig. 3 operating rod 74 through a solenoid (164). In the event of failure of the actuating means, fragmentation is initiated automatically on descent of the spent rocket, through an atmospheric pressure operated device (128), Fig. 4 (not shown). The secondary charge 50 is protected by an aluminized coating 160.
