Title: Improvements in or relating to digital storage units
Inventor: CHURCH JOHN HENRY
Filed: 1958-04-11
Abstract: 857,500. Mechanical digital-data-storage apparatus; temporary recorders. SIGMA INSTRUMENT CO. Ltd. April 22, 1959 [April 11, 1958], No. 11630/58. Classes 106 (1) and 106 (4). A digital storage unit or temporary recorder comprises a cylindrical drum which is a sliding fit in a coaxial sleeve 9 having three circular open ball tracks 10 forming with sixty-four transverse open ball tracks 5 in the adjacent surface of the drum a grid of successive sets of ball locations with three locations to each set, drive mechanism 34 for rotating the drum to move balls disposed in selected locations round the axis of the tracks 10, ball guides in a gap in the sleeve 9 for guiding each successive ball as it passes through the gap into the location in its set corresponding to a received signal and ball sensing arms 30 for sensing the individual location which contains a ball in each set as it arrives at the gap. The storage unit shown is used with apparatus designed to gauge a plurality of dimensions of a workpiece and records for each dimension gauged whether it is greater or less than or substantially equal to a chosen norm, i.e. it records in which of three categories the dimension falls. The guide 13 is fixed and has a tapered groove 15 in its concave underside communicating with a tapered groove 18 in the underside of the guide 14 which is carried by an arm 20 pivoted on a bracket 24 and centrally biased by two leaf springs 25 between two electromagnets 22, 23. The pawl 35 and ratchet 2 drive to the drum and is coupled to the gauging apparatus so that each dimension gauged is associated with a groove 5 in the drum and, as a signal is transmitted to one or other or neither of the electromagnets 22, 23 according to the category of the gauged dimension, the guide 14 is positioned with respect to the guide 13 so that a ball is guided into the appropriate one of the three locations in the associated groove 5. With the repeated stepping of the drum each groove 5 eventually passes under the three sensing arms 30, each projecting into a slot 27 communicating with a groove 10 so that a ball arriving under an arm 30 lifts it so that its associated arm 31 actuates a corresponding relay 32 which is connected to suitable mechanism for recording upon, e.g. a punch card. After passing the sensing arms the ball is guided to the centre ready to be positioned by the guide 14 in response to new signals. Superimposed discs, one with circular tracks 10, the other with radial tracks 5, may be used instead of a drum and sleeve. The three categories may be regarded as digits in a scale of three and similar apparatus may be made for storing digits in a scale of two.

Title: Brake linkages for motor vehicles
Inventor: MANNING WALTER
IPC: B60T11/04
Filed: 1966-03-18
Abstract: 1,068,268. Hand brake linkages. FORD MOTOR CO. Ltd. March 18, 1966, No. 12135/66. Heading F2E. In order to achieve quick take-up in the hand brake linkage of a heavy vehicle, a lever 15, forming part of the linkage 18, 19 to the brake 21, has a longitudinally movable pivot, comprising a pin 16 engaging a slot 17 in a plate 14 fixed to the vehicle body 11, and, in response to wind-up of the axle 12 caused by the braking action acting in one direction (the rearward direction, as shown), the pin 16 is moved in a direction such as to reduce the travel necessary to fully apply the brake, this being effected by the supplementary linkage shown. For this purpose, the supplementary linkage consists of a link 23 connected at 24 to the lever 15 adjacent to the pin 16, or alternatively, on an extension of the pin 16, and having its rear end passed through an aperture in an arm 22 upstanding from the axle 12 and engaging the rearward side of the arm via locknuts 25. A spring 27 normally maintains pin 16 at the forward end of slot 17 and provides for lost motion so that, when the brake is applied with the vehicle travelling forwards, wind-up of axle 12, allowed by the leaf spring suspension 20, merely compresses spring 27, while, when the brake is applied with the vehicle travelling rearwards, axle wind-up causes the arm 22 to pull on the link 23 and move the pin 16 rearwardly along the slot 17 to reduce travel of the hand brake linkage. In a modification (not shown), a second arm depends from the axle 12 and is connected via a second supplementary linkage to the point 24, so that quick take-up is effected in both forward and rearward directions of travel of the vehicle.
