Abstract: 295,780. Graseby, R. C. May 31, 1927. Winding-apparatus, electric.-A clock is wound by an electric motor, the switch of which is controlled by a threaded nut which moves along the winding arbor of the spring and is acted upon by a pin attached to the spring barrel. There is preferably a delay in the actuation of the switch; the motor is of the kind described in Specification 290,006, [Class 35, Dynamo-electric generators &c.]. A gear wheel 2 on the spring arbor 1 is driven through-wheels 3 and 4 from the motor. A spring 10 secured at 11 to the upper plate 8 has a pin 12 carrying a roller 13 in the path of the disc 5 which is integral with the nut moving on the arbor 1. A pin 6 on the barrel 7 fits loosely in a hole in the disc 5. Integral with the spring 10 and movable in a plane at right angles to it is a spring arm 14, which arm when the disc 5 raises roller 13 and spring 10, is raised into the path of a pin 16 on an arm 17 pivoted to the wheel 2. A spring 18 holds the pin 16 against the spoke of the wheel 2. 19 is a fixed stop and 15 the motor switch. When the motor winds the arbor 1 the disc 5 rises up the arbor and raises arms 10 and 14, so that when the wheel 2 has moved sufficiently for arm 17 to wipe past the stop 19 the spring 18 brings the pin 16 sharply against the arm 14, the free end of which opens the motor switch 15.

The projections overlap, as shown in Fig. 1, in order that when a key 1 is depressed, its stem 6 may engage between the projection 5 of the corresponding lever 2 and the oblique surface of the projection 4 of the adjoining lever of lower value, thus rocking the lever 2 and all those levers of lower value to displace a corresponding number of guiding-members. The keys 1 are looked in the depressed position by means of a spring-controlled locking-plate 8 which is adapted to engage a shoulder on the key stem.
Patent GB-147477-A (GB)
Abstract: 147,477. Reisser, A. Aug. 21, 1913, [Convention date]. Multiplying and dividing apparatus. -Relates to calculating-machines of the Odhner type, having a single key bank, with two totalizing-counters; and comprises means for disabling one of the counters or combining both counters for similar or dissimilar actuation. The sliding carriage is mounted on a base 7 having three walls 36, 37, 35 carrying the various spindles for the quotient and first totalizing-counter. The second totalizing-counter is carried in a frame pivoted at 39. The operation of one or both the two counters is controlled by the position of a frame 52, Figs. 1 and 8, carrying transmission pins, and pivoted at 44 and set by a bail 50, engaging a lever 48 adapted to be engaged by a cam 49 which is operated by a slide 53 on the right hand pinwheel member. The cam 49 is disa,bled by being moved laterally by a setting-lever (not shown). The relative direction of rotation of the counters depends on whether one or both of the transmission pinions 45, 46 for each denomination is in action. A similar pair of transmission pinions connect a pinion 32 on the shaft 33 of the second counter with a pinion 31, Fig. 5, loose on a shaft 15 of the first counter and operable as one nf a pair 13, 31, mounted loose on adjacent ends of alined shafts 14, 15 on the quotient and first counters, the pinion 13 being driven by a wheel 12 loose on its shaft, but actuated by the main shaft through a pinion 11 on a shaft 9. By this gearing the transfer mechanism of the two counters and of the quotient counter is operated. The rocking frame 52 for the transmission gearing is locked by a spring plunger 127, Fig. 8, set by a lever 124. Transfer mechanism.-Transfer is effected in the quotient and second counter bv two toothed disks 18, Figs. 5 and 6, which when engaged by the transfer stud on the counter-wheel are thrust along their squared shaft laterally against the action of blade springs 23. This brings the disk affected into the path of the next higher wheel, where it is held by a spring pawl 22 engaging an eccentric groove 19 in its hub until rotation of the shaft 16 effects the transfer. The spring pawls 22 escape from the locking grooves at the outer part of the eccentric, and the springs 23 slide the disks to normal position. The teeth on the disks 18 are differently spaced in gradation so as to effect transfer successively. The Specification as open to inspection under Sect. 91 (3) (a) also describes means by which the carriage is laterally spaced step by step, comprising a pair of keys, Fig. 5, the rear ends of which engage projections on a pair of vertical slides that carry pawls oppositely set to engage reversed ratchet wheels on a spiral cam shaft engaging a position pin on the carriage. Each key lever has an offset to engage a nose on the opposite slide and disable it while operating its own. The Specification as open to inspection as above also describes the keyboard mechanism described in Specification 169,983. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1291046 Semi-conductor oscillator circuits WESTERN ELECTRIC CO Inc 31 March 1970 [1 April 1969] 15128/70 Heading H3T [Also in Division-H1]  An assembly incorporating a varactor diode<SP>,</SP> bulk effect device, or avalanche diode is provided with means to RF decouple a D.C. bias source. Fig. 2 shows an IMPATT diode oscillator in which the diode 11 is mounted in a cavity structure defined by an inductive bridge 17 (which forms a resonant circuit with the diode which at the bias is equivalent to a parallel combination of, a capacitor and negative resistance) and an assembly composed of conductive layers 12, 14 and insulating layer 13. The D.C. supply is connected across these conductive layers which form a capacitor of sufficiently high magnitude that they are at virtually the same RF potential. The circuit is tuned here by making the dimension 1 < #/4 though other circuits may use 1 = #/4 (pure resistance) and 1 >#/4 (capacitive bridge). The oscillator output is taken from strip line 19 (operating with composite ground plane 12, 14) fed via the adjustable capacitance between its end 18 and the bridge 17. The line may be further coupled to a coaxial line or wave-guide. In a variant one half (l) of the bridge may be omitted. As shown, the heat sink 16 is of beryllia but instead the heat sink may be of copper and may itself act as the lower conductive layer 12. In the variant of Fig. 4 the conductive heat sink 16 carries insulation 13 and the conductive layer 14 acting as the other bias conductor. The upper section is an inverted strip line 18 having insulation 23 over the line 18 and bearing the bridge 17 connected by metal studs 20 to the layer 14. Further components may be formed on the strip line substrate 22 such as those necessary for down-conversion, up-conversion or phase-locked operation of the oscillators. .
