Title: Improvements in or relating to measuring apparatus using electrical oscillations
IPC: G01L23/32
Filed: 1951-03-05
Abstract: 712,527. Frequency measurements. GARNON, G. E., and FLEURY, R. F. L. March 5, 1951, [March 3, 1950.] No. 5329/51. Class 37. [Also in Group XXXVIII] In apparatus for measuring the variations of frequency of an alternating current produced by the variations of a physical quantity by determining the voltage developed across a tuned circuit, the resonant frequency of the tuned circuit is adjustable so that the range of frequencies due to the varying physical quantity occurs on a linear part of the resonance characteristic. For determining the frequency of the pressure variation inside the cylinder 3 (Fig. 2) of an engine, a condenser 6 whose capacity is determined by the instantaneous pressure inside the cylinder forms a resonant circuit with a coil 7 for determining the frequency of oscillation of a valve 8. The output from this valve, comprising frequencymodulated A.C., is fed through an amplifier and amplitude limiter (not shown) to a tuned circuit comprising a coil L in parallel with an adjustable condenser C1, the variations in voltage across the tuned circuit LCI being rectified by a diode VI, and the LF variations taken through an HF filter C 2 , S, C 3  to a potentiometer Pi feeding an oscillograph (not shown). A galvanometer G biased by an external battery to read zero when the oscillating frequency is in the middle of the linear part of the resonance curve may be used to adjust condenser CI for other mean frequency values. The galvanometer G may alternatively be unbiased to measure the varying rectified voltage from VI . The resonant circuit LC may be replaced by two series resonant circuits L1CV1, L2CV2 (Fig. 4) the condensers CV I , CV2 being mechanically coupled, and their resonant frequencies F2, F<SP>1</SP>2 (Fig. 5) adjusted so that the mean frequency of the oscillations occurs at the interception M of the resonant characteristics, the galvanometer G then reading zero for the static value of condenser 6.

Title: Improvements in high speed automatic electric circuit breakers
IPC: H01H71/50
Filed: 1934-02-19
Abstract: 425,646. Automatic circuit-breakers. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Vasteras, Sweden. Feb. 19, 1934, No. 5445. Convention date, March 1, 1933. [Class 38 (v)] In a rapid acting circuit-breaker the " kneeloose " tripping toggle is formed by a roller 3 carried by the contact arm 1 and a link 2 pivoted to an arm 8 movable about a fixed pivot, the lower end of the arm 8 being normally held against the shaped end of a manuallydepressable tripping lever 7. In the " closed " position shown, the link 2 is held against a fixed stop 11 by a laterally-acting spring 10, the link and roller thus forming a slightly underset toggle of which the three pivotal points formed by the pivot of the roller and that of the link and the line of contact between the roller and link lie almost but not quite in a straight line. In this position the moment of the lateral spring force about the link pivot exceeds the opposed moment Pr due to a powerful throw-off spring 4 acting on the contact arm 1. Attached to the contact arm is a bar 6 connected by a pin-and-slot to the armature 5 of an overload magnet and when the latter is sufficiently energized it acts upon the contact arm and increases the moment Pr about the pivot of the link 2 until it becomes greater than the moment of the force 10 about this pivot. The link 2 accordingly commences to move away from the fixed stop 11 and once the tripper motion is initiated it proceeds with extreme rapidity until the parts are in the position shown in Fig. 2. Resetting of the circuit breaker is effected by first depressing the lever 7 so that the link 2 is moved by its spring 10 against the fixed stop 11 and then rotating the lever 8 in a counterclockwise direction. During the resetting a pin 12 at the lower end of the contact arm 1 moves to the left in a fixed guide slot and the contacts engage with a wiping action. The overload setting may be varied by adjustment of spring 13. In an alternative arrangement, Fig. 3, (not shown), the release magnet is provided with series and shunt windings to operate on reversal of current.

[Also in Group XIII] Freezing apparatus of the kind comprising a conveyer carrying the goods through a freezing chamber from a loading position to an unloading position has the freezing chamber vertically disposed, the conveyer 12, 14 being arranged to carry the goods first dowwvardly from a loading hatch 11 to the tower part of the chamber and then upwardly to the unloading position 15, passing through a plurality of superposed cold air circuits 32, 34, 36 the cold air in each circuit passing first across an ascending portion of the conveyer and then across a descending portion. The food to be frozen is transferred on trays from the preparation room to the loading and unloading room 10, shown in plan in Fig. 1, by a monorail conveyer with slings 21 having end plates 22. The room 10 is maintained cool by refrigerating coils in casings 17 through which air is circulated and expelled through gratings 19. To prevent loss of cold, the slings 21 enter the room 10 through an air lock 24, of cross section corresponding to that of the end plates 22 and having a fan 26 which draws air from the inner end of the air lock and ejects it to the outer end. A similar air lock 28 is provided where the monorail conveyer leaves the room 10. From the slings 21 the trays are transferred to the down conveyers 12 which comprise two pairs of endless chains carried on shafts 8 and carrying tray-supporting runners. At the bottom of the freezing chamber the trays are automatically transferred to a crossconveyer 13 and to the up conveyer 14 which takes them back to the unloading hatches 15. In the first, second and third floors cooling coils 31 are arranged and air is forced by fans 35 through the closed circuits 32, 34, 36 including the conveyers 12, 14 and the cooling coils, the cold air first passing over the trays which have been longest in the cooling chamber. Side plates 33 between the conveyer chains force the air to pass between the trays. The cooling is controlled by by-passing some of the air through ducts 37 adjacent the down conveyer, through valves controlled by a thermostat 43. The loading and unloading stations may be on different floors.
