Filed: 1974-01-29
Abstract: 1501391 Ratchet screwdrivers M A MUMFORD 22 Jan 1975 [29 Jan 1974] 04144/74 Heading B3N [Also in Division B4] A ratchet action screwdriver has a shaft 2 formed with at least two drive receiving surfaces 3, a handle 1 having a cylindrical internal bore 8, Fig. 2a, which receives the shaft, a respective rolling element 4, 5 located between each surface 3 and bore 8 and control means, cage 7 with arms 6, engageable with the elements 4, 5 and movable relatively to the shaft between a first position, Fig. 2a, wherein rotation of the handle clockwise wedges each of the elements 4, 5 between the surfaces 3 and bore 8 so that the shaft rotates with the handle but not in the anticlockwise direction, and a second position, Fig. 2b, not shown, wherein the elements are similarly wedged to rotate the shaft with the handle in the anticlockwise direction but not in the clockwise direction. The arrangement may be such that a third intermediate position, Fig. 2c, not shown, is possible where the handle and shaft are locked against relative rotation in both directions. In Fig. 1 the handle comprises two relatively rotatable portions 9, 10 of plastics material each having a respective steel insert 12, 13 providing the cylindrical bores for respective pairs of rolling elements 4, 5 the arrangements being such that by gripping one portion in one hand and the other portion in the other hand the shaft may be driven by relative oscillating rotary movement of both hands. The control means, cage 7 may be retained in its adjusted rotated position by a spring-loaded ball detent arrangement 15, 16 engaging in depressions (19a-19c), Fig. 3, not shown, in a ferrule 18 fixed to the shaft. Alternatively, the control member 207, 214, Fig. 5, may be spring loaded relative to the shaft so that teeth 215 on control arms 6 releasably engage teeth 219 on a nylon washer 222 held to the shaft. In Fig. 6, a similar washer 322 has an integrally formed resiliently bowed portion 326 supporting teeth 319a-319c to urge the teeth into engagement with teeth 315. While in Fig. 8 teeth 415 on an annulus connected to control member (414), Fig. 7, not shown, by ribs 427 surround and engage teeth 419a-149c on a part 422 of a ferrule (418) fixed to the shaft. In Figs. 9, 10a and 11a the shaft 502 is square in section and has four rolling elements controlled by four control arms 506 restrained in the adjusted position by spring loaded ball 515 engaging a side of the shaft. The "flats" or sides of the shaft in any embodiment may be convex and balls may be employed instead of rollers 4, 5. Tapered rollers may alternatively be used and the two pairs of rollers in Fig. 1 may be replaced by one pair of longer rollers. A hexagonal shaft with three co-operating rollers is also mentioned.

Title: Improvements in brake control mechanisms
IPC: B61H15/00
Filed: 1926-02-16
Abstract: 247,954. Athimon, F. Feb. 17, 1925, [Convention date]. Compensating for wear; force-transmitting mechanism.-Vehicle brakes automatically adjusted for wear of the brake blocks are provided with a controlling device for preventing untimely operation of the adjusting means due, for instance, to shocks from the unevenness of the road. The brake control is of the type comprising a cam having a rapid slope for obtaining the preliminary stroke and a more moderate slope for the stroke corresponding to effective braking. The preliminary stroke is obtained by bearing on a lever having the same outline as the cam and held in position under a tensioning sufficient to withstand additional effort due to an improper adjustment. Its displacement raises the adjusting pawl out of action. The lever 3 pivoted at 4 on the cam 1 secured to the pedal 2, bears on a roller 7, mounted on an axle 11, and on an abutment 6 of the cam 1. The brake rod 12 passes through a part 8 of the axle 11 of larger diameter carried in a forked part of a lever 9 which is pivoted on the vehicle frame. The lever 9 carries the adjusting pawl 15 co-operating with a ratchet-wheel 20 adjacent which is a nut 22 mounted on the rod 12 and in contact by means of an extension 23 with a cylindrical recess in the part 8. If the preliminary stroke is increased by reason of wear, the lever 9 is driven further out and the pawl 15 slips by one tooth on the wheel 20 and turns it on the brake returning to inoperative position. If improper adjusting effects have taken place resulting in excessive pressure of the wheel 20 on the part 8, the increased tangential pressure on the lever 3 overcomes the tension of a spring 5 and the lever 3 is turned into contact with a stud 27 on a lever 24 pivoted on the lever 9. An arm of the lever 24 is moved to engage a notch 18, Fig. 2, in an extension of the pawl 15 which is thus moved out of engagement with the wheel 20. When the brake returns to inoperative position, a stud 26 on the lever 3 acts on a further arm of the lever 24 which is disengaged and the pawl released. A spring 21 riveted on the pawl allows a slight back motion of the pawl without moving the wheel 20. The attaching point of the spring 5 to the lever 3 is adjustable. The cam 1 may be mounted on the lever 9 and the roller on an arm secured to the pedal.

Title: Improvements in and relating to radio relative velocity meter
IPC: G01S7/282
Filed: 1941-04-17
Abstract: 581,166. Radiolocation. FORMAN, J., and PYE, Ltd. April 17, 1941, No. 4987. [Class 40 (v)] In order to determine the relative velocity between two objects, periodic radio signals are transmitted from one object to the other and a proportion of each of the received signals is delayed by a constant delay interval and mixed with a part of a following undelayed received signal, the resultant mixed signal being measured to indicate the relative velocity. A pulse generator 1 keys an ultra-highfrequency transmitter 2 which radiates from its beam antenna 3 a pulse of radio waves. These are reflected from the object 4 and received on an antenna 5, and passed to a receiver 6, a portion of its output being fed to a time delay circuit 7 and an equaliser 14. The output from the time delay circuit contains a reversed pulse and this also is fed to the equaliser 14 where both the delayed negative pulse and the undelayed positive pulse are limited to the same amplitude. The two pulses are fed to the two grids of a tetrode bi-grid valve 8, the grids of which are biassed to operate on a linear portion of the valve characteristic. A current meter 11 is included in the anode circuit. Where there is no relative velocity, Fig. IIa, a pulse O1 is transmitted and received after reflection after a time interval T depending on the distance as a positive equalised pulse, which is fed to one grid of the valve 8. The same received pulse is also fed to the time delay circuit 7 which passes on a negative pulse at an interval of time T just less by half a pulse width than the period of the generated pulses. This delayed and equalised pulse is fed to the other grid of the valve and almost coincides with the second received pulse R2 originated by 02. Similarly, the pulse R2 causes a delayed negative pulse D2 almost coinciding with R3 and so on. A definite anode current therefore flows and corresponds to zero velocity. Fig. IIb shows the conditions when a pulse arrives at an interval T-t1, where t1=half a pulse width. The negative delayed pulses D1, D2, D3 are applied to one grid at such an instant that they coincide with the next directly received pulses and there is no anode current, representing maximum positive speed. At maximum negative velocity a steady current is read on the meter. Between these valves the meter reading indicates the relative velocity.
