The lock is made from a metal sheet 26 (Fig. 3, not shown) having opposed base portions 29, 30 with parallel faces 27, 28, two angled top surfaces 31, 32 which merge into a bridge 35 via radii 33, 34; the underside of the bridge 35 is joined to the faces 27, 28 by ribs 36, 37. The sheet then has transverse slots punched therein after which it is crimped to form arcuate sections 49 (Fig. 7, not shown) joined by flat parts 50 beyond the slots 47. The sheet is severed along either side of the bridge to provide sheets 51, 52 which are cut to length and formed round a bending shoe into a lock, which, when the ends are joined, incorporates three to six longitudinal slots; the severing operation may take place during or after the bending operation. The locks may be formed from a metal sheet having the sectional shape of one lock only.

Abstract: 1,195,371. Programmed control of machinetools. ALFRED HERBERT Ltd. July 25, 1967 [July 28, 1966], No.33929/66. Heading G3N. [Also in Division B3] In a lathe having a tool changing apparatus, six bi-stable circuits B1-B6 Fig. 20, are controlled by switches RS1-RS6 in an electronic logic circuit, actuated by tool identification keys situated in the tool changing apparatus, the circuit operating when a tool magazine is rotating. The circuit includes six input terminals 230-235 from a tape reader, which provides instructions to a tool number, a tool station selection, and a park position, and a gate N 20  is interrogated. If the binary coding on the tool identification key matches the coding called for by the tape, a pulse is produced by a monostable circuit M2, so as to stop the rotation of the tool magazine. Terminals 236, 228 are connected to a logic circuit which passes an output to terminal 236 whenever a tool selection operation is required; the magazine is rotating, and the coding called for is other than 000000. Under any other conditions, no signal is applied to terminal 236, but a continuous signal is applied to terminal 228 to hold bi-stable circuits B1-B6 in their reset conditions. The coding grooves in the keys are read by switches and it is stated that coloured machines read by photoelectric cells could be employed.

Abstract: 519,293. Automatic speed control systems. HOWARTH, F. C. April 5, 1939, No. 34854/38. [Class 38 (iv)] A speed-controlling device for a motor vehicle comprises switch contacts D<1> in the ignition circuit F', F<2>, these contacts being normally closed by a solenoid D, the solenoid circuit, and therefore also the ignition circuit, being broken when the vehicle reaches a pre-determined speed, a hand - operated switch a being also provided whereby the solenoid can be short circuited when desired to put the speed control out of action. In the construction shown a cam c<1> on the speedometer needle c maintains contact with a strip c<2> until the predetermined speed limit is reached, and the solenoid D is energized and closes the contacts D' to complete the circuit of the ignition coil F. When the cam c<1> leaves the strip c<2> the solenoid and ignition circuits are broken. The switch a, in the position shown, completes the circuit of a lamp A<1> on the dash and a lamp A or semaphore on the outside of the car to give warning that the speed control is in use. If the' switch a is moved to the position shown -in broken lines the lamps A, A<1> are extinguished and the solenoid D is shortcircuited so that the ignition circuit cannot be broken by the speedometer contact. F' is a buffer coil to prevent damage to the ignition coil. In the case of magneto ignition the contact D' may be in the sparking plug leads.
