Abstract: 661,657. Velocity-modulated tubes. STANDARD TELEPHONES & CABLES, Ltd. (Materiel Telephonique Soc. Anon.). May 21, 1948, No. 13794/48. Class 39 (i). An electron velocity modulation tube comprises a first and a second hollow wave - guide, a cathode adjacent the first waveguide extending along a length thereof and adapted to project a beam of electrons across the first and then the second waveguide, a reflector adjacent the second wave-guide coextensive with the said cathode adapted to reflect the said beam back across the second and first waveguides and a reflectionless connection coupling one end of the first wave-guide to the opposite end of the second wave-guide, the tube being dimensioned so that the waves in the two guides crossing the same electron path differ in phase by onequarter of a wavelength and the electron transit time from the middle of the first guide to the middle of the second guide is a quarter period of the oscillations transmitted through the said guides. The conditions are such that the oscillations set up in the wave-guides by the passage of the electron beam therethrough are attenuated in their travel in one direction along the system and are amplified in the other direction, so that a travelling wave, increasing from zero amplitude at the end of one wave-guide to a maximum amplitude at the end of the other wave-guide, is generated and maintained in the wave-guides. In one embodiment, Figs. 5 and 6, an evacuated envelope contains a pair of wave-guides 14 and 15 having a common wall 16 and shaped to conform to an arc of a circle an integral number of wavelengths long. A cathode 17 and focusing electrode 18 are positioned outside the circle and a collector electrode 19 is mounted inside the circle opposite the cathode. The diameter of the circle may conveniently be chosen so that the coupling between the ends of waveguides 15 and 16 may be effected by a quarter wave section of wave-guide completing the circle. In a further embodiment, Fig. 11, two wave-guides 20 and 21 are mounted together with a common electron permeable wall. The outer walls of the respective wave-guides have re-entrant portions in which are mounted respectively a reflector electrode 23 and a cathode 24. The system is curved along the arc of a circle and the wave-guides are connected together as described in the previous embodiment. In both embodiments the electron beam is collected by the outer wall of the first guide after its return transit therethrough and the frequency of oscillation of the tube is varied by changing the potential of the reflector electrode.

Patent GB-723574-A (GB)
Abstract: 723,574. Cash registers. NATIONAL REGISTRIER KASSEN GES. March 13, 1953 [June 10, 1952; Jan. 23, I953], Nos. 14566/52 and 2078/53. Class 106 (I). The locking mechanism of a cash register or accounting machine is controlled by certain keys of the keyboard, so obviating the necessity for a removable key; depression of one, or a predetermined combination of the keys rendering the mechanism effective to lock the machine against operation, whilst depression of another combination of the keys renders the mechanism ineffective so that the machine can be released for operation. The keys in question are indistinguishable from other keys, usually provided; e.g., and as shown, they are what would normally be the " 5 " to " 9 " keys 22, 23 in the highest order amount bank and retain those captions. Secured to the stems of the " 5 " and " 9 " keys are long pins 34 overlying a pair of slides 30, 31. These slides are formed with cam edges 33 engaged by the pins 34 and are cammed downwardly on supporting studs 32 when either the " 5 " or " 9 " key is depressed, cam slots 29 in the slides then rocking latches 25, 26 to engage behind, and obstruct, a bail 10 pin-and-slot connected to a latch 5 normally locking a motor release spider 60. The latch is then maintained in locking engagement with the spider 60 so that the motor bar 57 is ineffective to release the machine. Moreover, the keyboard is locked, lugs 21 on the bail 10 obstructing the key-bank looking slides 18. The slides 30, 31 are retained set and the locking mechanism effective by a detent 37 engaging over noses 39, 40 on the slides. To unlock the machine, both the " 6 " and the " 8 " keys 23 must be depressed. Pins 41 on these two keys engage cam edges 42, 44 on the slides, restoring the slides upwardly and disengaging the latches 25 and 26 from the bail 10. Upon now operating keys to set the machine for an operation, the now freed bail 10 will be rocked by a key-bank locking slide 18 and the latch 5 removed from the spider 60. When, therefore, the motor bar 57 is depressed to initiate the operation, the spider, released both by the latch 5 and motor bar, is rocked clockwise by its spring 62 so operating the machine release shaft 64 to actuate the motor switch member 66 and engage the clutch 52. An arm 72 on a shaft 71 normally obstructs movement of the motor bar 57, but is rocked clear by engagement of a pin 69 on the key lock slide 18 of the right-hand key-bank with a second arm 70 on shaft 71. The keys of the right-hand bank, though shown as amount keys 15, would normally be control keys and the arm 72 ensures that one such key is operated before the machine is released. Where the main shaft 1 is adapted to be hand driven, a part 4 of the latch 5 is adapted to engage between the teeth of a drive gear 2 on the shaft to lock the machine against operation. Specification 702,495 is referred to.

Patent GB-2015843-A (GB)
Title: Circuit for setting three levels of current in inductive loads such as solenoids
IPC: F16K31/06
Filed: 1979-02-06
Abstract: Comparator means CP1 respond to the current levels through an inductive load L1 to generate HIGH and LOW level outputs causing first switch means Q1 to connect and disconnect power to the load. Initially the load current rises until it exceeds a first or peak load-actuation level, a flip-flop FF1 responds to the corresponding change in comparator output level to change the sensitivity to the load current by disconnecting an auxiliary sense resistor R15 coupled to the sense input of the comparator means. The same comparator change disconnects the power, the current now flowing via Q2D1 falls to a second level whereupon the comparator connects the power again, the subsequent maximum current being at a third level. Thereafter the current oscillates between the second and third levels, these being sufficient to maintain actuation of the solenoid armature. At turn off, Q1 and Q2 are opened and the load current then passes via Z2, R1 and Q7 to rapidly reset the armature. In one embodiment, Fig. 4 a one-shot multi-vibrator Q25, D6, C7 prevents disconnection of the auxiliary sense resistor for a fixed period after the commencement of a load actuation signal. <IMAGE>
