Title: Electric control device
IPC: B64C27/32
Filed: 1962-06-07
Abstract: 991, 732. Electric control systems. KAMAN AIRCRAFT CORPORATION. June 7, 1962 [June 7, 1961], No. 22146/62. Heading G1N. [Also in Division B7] The control rod 10 (Fig. 1) of a helicopter rotor pitch-control system is coupled to a hydraulic servomotor 18 via a force rod 14 incorporating a differential transformer measuring the force applied, the output circuit of the transformer containing ten microswitches which are operated only after the applied force exceeds a predetermined value to allow the servomotor to assist or replace the manual control. The rod 14 comprises two parts 47, 48 (Fig. 2), the former carrying the windings of the transformer 82 and the latter being attached via rods 94, 96 to the core 84. Relative movement between the parts 47, 48 in or out against a spring 72 produces corresponding movement between the windings 82 and core 84 of the transformer, but the output from the secondary windings 122 (Fig. 4) is open-circuited by one of the microswitches 108 until an extension 98 of rod 94 operates one or the other switch, depending on the direction of movement. The signals from the transformer 82 may be added at 40 to those from an altimeter 46 which is normally used for automatic control of the pitch of the rotor blades.

Title: Improvements in and relating to dog clutches
IPC: F16D11/10
Filed: 1959-06-29
Abstract: 902,830. Positive clutches. MAYBACH MOTORENBAU G.m.b.H. June 29, 1959 [Aug. 13, 1958], No. 22243/59. Class 80 (2). Baulking means preventing engagement of dog clutch teeth 13, 14 for one direction of relative rotation of the clutch parts 11, 12, comprises a baulk ring 15 splined to the clutch part 12. When the dogs 13 are rotated clockwise relative to the dogs 14 (looking downwardly in the Figure), the baulk ring is held in its outermost position, projecting beyond the dogs 14, by a stop 21 on the ring being held between an inwardly-extending part 22 of the clutch part 12 and a holding ring 17 which is itself prevented from axial movement by a peripheral extension 24 engaging an abutment 34 on the part 12. Holding ring 17 has a splined connection with a ring 16 which has ratchet teeth 27 and which is urged upwardly by a spring 18 until a rim 28 engages beneath the holding ring 17. Dogs 13 engage the teeth 27 and move the ring 16 clockwise until the extension 24 engages a stop 33 whereupon ring 16 is depressed against the action of the spring to allow ratcheting of the teeth 27 on the dogs 13. The ring 16 is relatively light and the vibration is negligible compared to that which would occur upon ratcheting of the dogs 13, 14. When the relative rotation of the clutch parts reverses, dogs 13 engage the teeth 27 and move the rings 16, 17 anti-clockwise until the extension 24 clears the abutment 34, whereupon the dogs 13 can move the baulk ring 15 axially and engage the dogs 14. In modifications, instead of the dogs 13 engaging the baulk ring 15 and the teeth 27, a ring may engage the baulk ring 15 and a toothed rim engage the teeth 27. Furthermore, the baulk ring 15 may be formed as a roller or ball-bearing, or bearings may be provided in the parts of the dogs 13 contacting the baulk ring to reduce friction.

Filed: 1923-09-05
Abstract: 225,620. Consolidated Pneumatic Tool Co., Ltd., and Kennell, A. J. Sept. 5, 1923. Attachments for inserting screws.-A screwdriving attachment for use with an electric, pneumatic or other machine comprises a sleeve 1 having resilient members 10 adapted to support and centre the screw and embracing a slidably mounted driver 2 which is screwed at 4 for attachment to a driving shaft or carries a tapered driving shank. The motion of the driver is limited by a pin 6 and slots 5 in the sleeve and is maintained in the retracted position by a spring 9. The length of the slots 5 may be such that the screw will be recessed into the work. The members 10, of which there are preferably two, are pressed inwards by a wire spring 11 which enters grooves in the sleeve and members to prevent rotation of the latter. The inner ends of the members are bevelled to facilitate insertion of the screw-head and to allow the head to be pushed out when the sleeve encounters the work. A radial pin in the sleeve prevents rotation of the spring 11 and ensures an equal pressure on each member. In a modification the driver is formed in one with the screwed socket 4 or wit.h a taper shank which replaces the socket and the pin 6 is fixed in the sleeve, a slot 5 being then provided in the driver, or alternatively the pin may be fixed to the driver. The latter may be adapted to operate on screws having the head provided with a driving recess other than a straight slot. The Provisional Specification states that recesses for holding the screw-head may be formed in the members 10.
