Title: Permutation lock for safes and the like
IPC: E05B37/12
Filed: 1922-10-30
Abstract: 207,684. Fraigneux (nÚe Nollet), L., and Fraig-neux, E., (trading as Etablissements L. Fraigneux). Oct. 30, 1922. Locks, permutation.-In a permutation lock in which a bolt is blocked by a pivoted member which can only be rocked clear of a pivoted spring pawl on the bolt to release the bolt when flat parts on rotatable hubs are turned adjacent to the member, means are provided for scattering the combination when the bolt is withdrawn or alternatively when it is shot. The member i pivoted at o has a finger n which controls its pivoted movement. Permutation elements are mounted on each side of the pivot o, above the member i on one side of the pivot and below on the other. They consist of knobs a with rigidly attached dials b on which letters or numerals are marked. Also rigid with the spindles are toothed wheels d. Rotatably mounted on the spindle are discs c with hubs having a flattened part k. Attached to each disc c is a spring f with a projection e which may engage between any pair of teeth on the wheel d, so that the discs c and hubs k turn when the knobs a are rotated to set the hubs to align their flat parts k so as to allow the member i to turn under the action ot its spring r. To change the combination, the projection e must be disconnected from the teeth of the wheel d. This is effected by pressing down a plate by means of a key inserted in the member g, inclined beaks on the plate engaging the springs f and releasing the projection e from the teeth of the wheel d, allowing the discs b to be rotated to the new combination. The projections e re-engage the wheels d when the plate carrying the beaks j is returned. The spindles of the rotatable setting knobs a carry cams m at their inner ends, these cams being turned during the setting of the hubs of the discs c. On operation of the bolt, a plate l is carried with it and cut away parts thereon, shown in Fig. 1, engage the cams m, causing them to rotate to scatter the combination. Fig. 16 shows the bolt C in its blocked position, a spring pawl s engaging the end of the pivoted member i. Setting of the hubs k results in the member i rocking out of the path of the pawl s, when the bolt can be withdrawn. The scattering of the combination causes the member i to rock, depressing the pawl which snaps back into blocking engagement, when the bolt is again shot.

Title: Improvements in or relating to electrical transducers and assembly thereof
Inventor: BLASTIC JOSEPH EUGENE
IPC: H04R29/00
Filed: 1969-06-12
Abstract: 1,245,014. Electromagnetic transducers. WESTERN ELECTRIC CO. Inc. 12 June, 1969 [14 June, 1968], No. 29834/69. Heading H4J. A transducer having a diaphragm-armature assembly, a magnet polepiece assembly and an associated inductive coil all supported by a frame is made by a method which includes adjusting the magnet-pole assembly to a desired position while frictionally holding it relative to the frame, and maintaining it at a desired position until it is rigidly secured by a solidified fixative, cement, resin or potting compound. A receiver having a central circular armature 23 (Fig. 2) mounted on a circular, inwardly bowed diaphragm 16 secured to a frame 12 (see Fig. 1) of metal or plastics material has a pair of polepieces 14 secured to a permanent magnet 13. Each polepiece 14 is T-shaped (Fig. 6) and comprises a central leg 14b extending through a coil 31, and two bent legs 14d. Pairs of legs 14d are disposed in a U-shaped receptacle (Fig. 7) formed as an integral part of the frame 12. Each receptacle has two opposite leg extensions 45, semi-circular recesses of which engage a U- shaped wire 61. The wire 61 has bowed legs which frictionally engage the polepiece legs 14d and temporarily support the magnet polepiece assembly during the adjustment of the air gap. After adjustment, a fixative 63, preferably in liquid form, is placed in each receptacle and hardened. Instead of the wire 61 there may be used hollow, resilient, plastics tubing (Figs. 9 to 14, not shown), metal strip (Figs. 15 to 17, not shown) or the receptacle walls may be formed with one or more integral projections adapted to frictionally engage the polepiece legs 14d (Figs. 18 to 20, not shown). Adjustment.-The assembly of magnet 13 and polepieces 14 (Fig. 8) is mounted between jaws 71 of a reciprocating ram 73. The receiver frame 12 has the diaphragm 16, armature 23 and coils 31 mounted thereon. The jaws 71 are lowered to bring the polepiece legs 14d into frictional engagement with the wires 61 and a 1000 Hz. signal is applied together with a D.C. bias of approx. 250 ma. to the coils 31. The bias current is of polarity to aid the magnet 13 in attracting the armature 23 until it touches the pole tips 14a. The jaws 71 are then retracted. The D.C. is gradually reduced to zero and then to - 150 ma. A calibrated microphone 81 receives the output signal and feeds a corresponding electrical signal to an oscilloscope 83. The acceptability of the transducer is determined. If necessary, the magnet 13 is partly demagnetized. Finally a signal which sweeps from zero to 4000 Hz. is applied to the coils 31 and if the output signal is satisfactory the leg portions 14d are embedded in fixative.
