Title: Condition sensing circuit
Inventor: FARMER EDWARD B
IPC: G01G23/18
Filed: 1960-05-27
Abstract: 932,129. Weighing apparatus. FAIRBANKS, MORSE & CO. May 27, 1960, No. 18821/60. Drawings to Specification. Class 143. [Also in Groups XL (b) and XL (c)] Relates to the provision in a printing-type weighing machine (generally of known construction, Figs. 1-4, not shown) of means to prevent the printing operation being initiated until balance is achieved and the shaft whose angular position indicates the weight is stationary. A slotted wheel or disc is mounted on the shaft and co-operates with a light source and photoelectric cell (see Group XL (b)) to cause the production of electric pulses whenever the shaft is rotating. The pulses are applied to a circuit, Fig. 5 (not shown), in which each pulse establishes a discharge path for a capacitor. The capacitor has a charge path which becomes effective in the interval between pulses, but the resistance of the discharge path is appreciably lower than that of the charge path, so that in the presence of pulses the capacitor remains substantially without charge. The resulting low potential across the capacitor causes conduction in a discharge tube and results in the energization of a relay whose contacts interrupt the printing control circuit. When the shaft becomes stationary and the pulses cease, or the shaft in slowing down reaches a speed such that the pulse repetition rate falls below a predetermined low value, the capacitor gradually recharges and after a delay causes the discharge tube to be cut off and the relay to be released, whereupon printing of the measured weight is effected. The provision of a delay in initiating printing is stated to be necessary to allow for overshoot in the weighing mechanism. The circuit includes means to adjust the delay and the amplitude of the pulses applied to discharge the capacitor.

Abstract: 1,097,617. Escapements. J. REICH. May 3, 1966 [May 11, 1965], No. 19355/66. Heading G3T. A timepiece escapement mechanism comprises an escape wheel 10, the teeth 14 of which cooperate with a pallet arm 5 attracted to its operative position by a permanent magnet 4. The pallet arm is pivoted on a pin 7 attached to a pair of balance wheel discs 2. A slot 3 enables the discs to be sprung on the balance staff 1 and a pin 6 prevents the pallet arm 5 touching the magnet 4. Anti-clockwise rotation of the balance wheel causes the pallet arm to rotate the escape wheel 10 against the locking action of a spring 11. During the clockwise rotation of the balance wheel, the teeth 14 pivot the pallet arm 5 away from the magnet 4 and the pallet arm therefore slips easily over a tooth before it is attracted back into a locked operative position by the magnet. In a modification, Figs. 3, 4 (not shown), the escape wheel is mounted at right angles to the plane of the balance wheel.

Title: Improvements in and relating to pawl-operated intermittent driving mechanism
IPC: B08B9/42
Filed: 1943-11-22
Abstract: 571,790. Ratchet gearing. WRIGHT, H. Nov. 22, 1943, No. 19484. [Class 80 (iii)] [Also in Group XXX] Consists in ratchet gearing, particularly applicable to the driving of a conveyer chain carrying the bottles in a bottle - washing machine, whereby each travel period is shortened and each dwell period correspondingly lengthened, as compared with the equal periods of known drives. The ratchet-wheel b, keyed to the driven shaft c, is actuated by a pawl e pivoted at d to a pair of arms f integral with collars g free to oscillate on the boss a of the wheel b. The arms are oscillated by a link k. Between one of the collars g and the wheel b is loosely mounted a thin supplementary ratchet n with teeth p of the same number and spacing as those on the wheel b, but with this difference, that while alternate teeth of the supplementary ratchet register with alternate teeth of the driving ratchet, the intermediate teeth of the supplementary ratchet project beyond the intermediate teeth of the driving ratchet. The pawl e is wide enough to engage the teeth of both ratchets. A counterbalanced check pawl r is shaped to engage the teeth of both ratchets. In the position shown in Fig. 1, the next stroke of the pawl e moves only the supplementary ratchet. On the return stroke, the pawl engages a tooth m of the driving ratchet. On the next return stroke, the pawl rides up on a tooth p and is thereby prevented from engaging a tooth of the driving ratchet. With this arrangement, the mechanism is run at twice its normal speed, whereby each travel period of the chain is now one-fourth and a dwell period three-fourths of the original period of a single reciprocation. A supplementary ratchet may be provided on each side of the driving ratchet and the supplementary ratchet may be provided with two or more successive projecting teeth to increase still further the dwell period.

Title: Improvements relating to the repetition of electrical impulses
IPC: G01R23/02
Filed: 1942-11-19
Abstract: 560,891. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., and CHRISTIAN, D. A. Nov. 19, 1942, No. 19631/43. Divided out of 560,887 [Group XL]. [Class 40 (iv)] [Also in Group XL] In order to repeat impulses with a standard break to make ratio for different impulsing speeds, the components of the received impulses are timed and the duration of each component of the repeated impulses is determined jointly by the durations of the corresponding and preceding components as received. In the repeater shown, relay AA which repeats the impulses received by line relay A is dependent on relays X, Y which operate in the anode circuits of valves XV, YV when condensers XQ, YQ have discharged to a certain potential. When A falls back at a break, XQ discharges slowly over resistance R2 until A re-operates and then at 3 times the former rate over resistances R2, R3 in parallel until XV becomes conducting, when X connects up AA. The end of the repeated break is thus delayed by a fixed time less a third of the received break. Similarly, when A pulls up at a make, YQ discharges slowly over R1 until A falls back again and then at <3>/2 times the former rate over Rl, R4 in parallel until YV becomes conducting, when Y releases AA. The start of the repeated break is thus delayed by the same fixed time less two-thirds of the previous received make. If the break and make periods of the received impulses are B, M, the break period of the repeated impulses is therefore B+(C-1/3B)-(C-2/3M) or 2/3(B+M), and the break-to-make ratio is 2 : 1. In the case of the first repeated break, however, since the previous received make is indeterminate, it is arranged that YQ is pre-charged from a potentiometer comprising resistances R1, R5 so that on the relapse of A the start of the repeated break is delayed for a suitable arbitrary period. The potentiometer charging circuit for YQ is opened at the first repeated break by dialling relay C or by a quick-operated relay in parallel therewith. Instead of single condensers XQ, YQ, use may be made of pairs of condensers which discharge at different rates and are started at different times, as described in Specification 560,887.
