Title: Improvements in and relating to arc lamps and circuits therefor
IPC: H05B41/19
Filed: 1946-03-07
Abstract: 643,445. Supply systems for discharge lamps. REICHINSTEIN, D. March 7, 1946, Nos. 7180 and 7181. Convention dates, March 7, 1945, and Sept. 12, 1945. [Class 38 (iv)] [Also in Group XL (a)] An arc lamp with incandescent electrodes and an auxiliary electrode is incorporated in a circuit including a transformer and a signal lamp which are so arranged that when connected to lighting mains an auxiliary arc can be caused to pass from the auxiliary electrode to one of the main electrodes, and when in addition the circuit to the main electrodes is completed, the signal lamp is illuminated and remains illuminated until the existing auxiliary arc has passed over to the main electrodes, whereupon the signal lamp is automatically extinguished and thereby indicates that the main electrodes can be switched over to the mains and the transformer put out of circuit. The circuit -diagram, Fig. 2, shows the main electrodes 37, 47, the auxiliary electrode 48, the transformer primary windings 36-46 and 38-39 and secondary windings 40-42 and 43-41, and the signal lamp 50. I, II, III, IV indicates a 4. or 3-step, 2-pole sliding lever or roller switch for effecting the following connections. Step I : 29 is connected with 33 and 30 with 34, whereby the main 51 is connected to the primary winding of the transformer. Step II: previous connections maintained and at same time 24 is connected with 26, and 28 with 27, whereby main electrode 37 is con. nected with terminal 40 of secondary winding, and terminal 41 of secondary winding is connected with auxiliary electrode 48. By pressing switch 35 the auxiliary electrode 48 is connected with the secondary winding of the transformer and becomes incandescent to cause formation of an auxiliary arc between auxiliary electrode 48 and main electrode 37. Step III: connections 29 and 33, 30 and 34, 24 and 26 are maintained while 28 is now connected to 26, whereby the other main electrode is connected with terminal 41 of the secondary winding of the transformer while the signal lamp 50 is connected into the circuit of the auxiliary arc. The arc then passes on to the second main electrode and, when the latter is sufficiently heated by the arc the lamp 50 is extinguished indicating that the arc lamp can be switched over to Step IV: wherein connections 29 and 33 and 30 and 34 are broken while 24 is connected with 29, and 25 with 30, thus excluding the transformer and connecting the lamp to the main. Step I can be eliminated.

Patent GB-814346-A (GB)
Title: Improvements in or relating to wave guide systems
Inventor: CHIRON BERNARD PIERRE
IPC: H01P1/365
Filed: 1957-03-06
Abstract: 814,346. Non-reciprocal waveguide devices. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES. March 6, 1957 [March 15, 1956], No. 7508/57. Class 40 (8). A non-reciprocal attenuator comprises a section 8 of rectangular waveguide along which a TE no  (where n > 1) wave may be transmitted and a number of ferrite elements 10, 11, 12 arranged in the section, the elements being subject to transverse magnetic fields. The elements are in the form of thin rectangular plates and are situated at points where the longitudinal and transverse magnetic components of the wave are equal, e.g. at points where the magnetic field of the wave is circularly polarized. For a TE 20  wave there are four such positions along the direction of the broad dimension of the guide and elements 10, 11, 12 are situated at three of these. Since the sense of rotation of the circularly polarized field at the position of plate 12 is opposite to that at the other two positions, it is necessary to provide two oppositely directed transverse magnetic fields in such a manner that the sense of rotation is positive (anticlockwise when seen in the direction of the field) for all three plates. Under such circumstances, the wave is absorbed in the ferrite elements. If the direction of propagation is reversed, the sense of polarization is changed from positive to negative and no absorption of energy takes place. The magnetic fields are produced by two U-shaped magnets (not shown), one for the plates 10, 11 and one for the plate 12. The guide section is connected at either end by mode-converters 6, 7 to waveguides 5, 4 which have half the width of the section 8 and support a TE 10  mode wave. The converters 6, 7 are in the form of H-bends, the corners of which are cut off by walls 17 of length a#2, where a is the wide dimension of the guides 5, 4. The walls 17 make an angle of 45 degrees with the axes of the guides.

Abstract: 1,207,562. Piezo-electric transducers. H. LIST. Feb.21, 1968 [June 14, 1967], No.8340/68. Heading G1N. To compensate for errors in measurement due to acceleration forces, a water cooled Piezoelectric transducer e.g. for measuring pressure, comprises a stack or set 12 Fig. 1 of quartz crystal wafers 11 responsive to a force to be measured applied to end portion 10 of a thin walled tubular spring member 7, and a compensating crystal or set of crystals 14 which under acceleration is acted upon by a mass 13 to produce an output of opposite polarity to that of the measuring crystals 12. The upper end of the tube member 7 is welded to an insert 2 and the member 7 holds the crystals and mass 13 under axial compressive pre-stress. Under acceleration conditions the crystals 12 produce an output dependent upon the combined masses of the end portion 10, a ring member 18 of a sealing membrane and a shim member 9 sandwiched between the crystals and portion 10. During calibration tests on a vibrating table, material is removed from the ring 18 and end portion 10 to reduce their mass until the voltage output of crystals 12 exactly balances that of crystal 14 due to acceleration of mass 13. Alternatively, the spring may be in the form of a membrane Fig. 2 (not shown), closing the end of the housing.
