Title: Improvements in electromagnetic driving devices for use with sound reproducing apparatus
IPC: H04R13/02
Filed: 1926-03-08
Abstract: 251,596. Gerns, W. H. April 29, 1925, [Convention date]. Magnetic instruments; loud-speakers. - An electromagnetic device, more particularly for actuating a large conical diaphragm or for use as a loud-speaking attachment for gramophones, comprises telephone receivers 2, 3 supported in an annular rim 1<a> on a base 1 or spaced apart by a member 4 formed integrally with an armature 5 which extends between the opposed pole pieces of the electromagnetic devices in the receivers. The armature may be formed with a substantially rectangular portion 17 directly over the pole tips. The pole pieces and coils are so arranged that when current flows in the coils it alternately strengthens one pair of magnets and weakens the other pair, whilst very small reluctance gaps 35, 36 are provided between the poles. When applied as a loud speaking attachment for gramophones, the member 4 has its ends 32, 33 spaced apart to allow the end 15 of the armature 5 to project therebetween. The end 15 is provided with a slot 16 adapted to be engaged by the gramophone stylus. Fig. 5 shows a construction of armature and spacing member which is employed when the device is employed for actuating a conical diaphragm as shown in Fig. 8. In this case the member 4 is formed as a complete ring and the armature is connected to the conical diaphragm 23 by a rod 22, which may be secured to the armature either as shown in Fig. 8, or to the extremitv of an external extension of the armature. The cone 23 is secured to the rod 22 through members 24, 25, 26. The Specification as open to inspection under Sect. 91 (3) (a), describes an alternative construction of spacing member and armature shown in Fig. 5 (Cancelled). This subject-matter does not appear in the Specification as accepted.

Abstract: 1,169,541. Ironing-m a c h i n e s . OPRIM SALES Ltd. 3 Feb., 1967 [14 Feb., 1966], No. 6398/66. Heading D1A. An electric ironing-machine of the roller and heated arcuate shoe type comprises a toggle action linkwork which moves the shoe into resilient contact with the roller and switches on the roller driving motor. As shown, longitudinal movement of a bar 10 against the action of spring 17 by a foot controlled Bowden wire 22 spreads the toggle 8, 11 to move an arm 3 pivoted at 5 and carrying the heated arcuate shoe 4 and also trips a motor switch 24 to commence rotation of the roller 26 before the shoe makes contact therewith. When the toggle 8, 11 is fully spread then pressure between the shoe and the roller is produced wholly by a spring 15 acting through the toggle linkage. An electric thermostat is provided to control heating in the shoe.

Abstract: 608,805. Electrolytic production of light metals. DU PONT DE NEMOURS. & CO., E. I. March 1, 1946, No. 6411. Convention date, March 1, 1945. [Class 41] An electrolytic cell for the production of light metals from a molten electrolyte, for example sodium from a mixture of sodium chloride and calcium chloride; comprises a central anode 3, a cathode 4 and a collector 7 for molten metal, the collector having a conduit 8 which extends up from below the level of the electrolyte and is insulated from the electrolyte by a jacket 16. The jacket may be filled with glass wool or asbestos. The upper part of the conduit 8 is provided with heat-radiating fins 14. Gas rising from the anode is withdrawn by way of a dome 10 and pipe 11. An agitating device, for example as described in Specification 463,663, may be provided in the conduit 8 to prevent calcium from sticking to the walls of the conduit. U.S.A. Specification 1,501,756 is referred to.

Abstract: 1,263,241. Corrugating by rolls. STEEL CO. OF WALES Ltd. 14 April, 1969 [9 Feb., 1968], No. 6428/68. Heading B3E. Cold roll forming apparatus for producing longitudinal corrugations in metal sheet is characterized in that an idler roll is provided in close proximity with the forming rolls, said idler roll being contoured to correspond with that part of the sheet-metal which has already been formed, the arrangement being such that said idler roll serves to maintain the configuration of the already formed part of the sheet as it passes said forming rolls. The first pair of forming rolls 11, 11<SP>1</SP> have central ribs for forming corrugations in the central portion of the sheet 13. The second pair of rolls 12, 12<SP>1</SP> have central cylindrical portions and side ribs for forming further corrugations in the sheet on either side of the corrugations already formed. A third pair of rolls 20, 20<SP>1</SP> form further corrugations in the sheet and these rolls also have a smooth central portion. Between the rolls 12, 12<SP>1</SP> and 20, 20<SP>1</SP> a frame 16 carries an idler supporting roll 17 contoured to fit the corrugations formed in the sheet. The frame also carries pivoted arms 19 between which is mounted an upper idler roll 22 also contoured to fit the corrugations but only in its central portion adjacent the smooth central portion of the rolls 12, 12<SP>1</SP>. A pressure bar 25 mounted on the arms can be adjusted by a screw member 28 to vary the pressure exerted on the sheet passing beneath the idler roll so that stretching of the corrugations formed by the first rolls 11, 11<SP>1</SP> is prevented.

Title: Improved process for treating ammonium chloride lyes in iron vessels
IPC: C01C1/16
Filed: 1923-03-07
Abstract: 196,585. Henkel et Cie, and Weber, W. April 22, 1922, [Convention date]. Corrosion, preventing.-In the evaporation of ammonium chloride .solution such as the residual lves from the ammonia soda process corrosion of the iron vessel is prevented by the addition of a zinc compound, or a galvanized vessel may be used. After concentrating and removing the ammonium chloride crystals the mother liquor which contains the zinc is mixed with an equal volume of fresh lye and again evaporated. In a modification a weak direct electric current may be passed through the liquor, in addition to adding the zinc compound, in the manner described in Specification 195,947. Alternatively a zinc anode may be used. In one example to a solution containing 15 per cent of ammonium chloride and 8 per cent of sodium chloride zinc chloride is added and a current corresponding to about .01 ampÞre per square decimetre passed through the liquor, using an iron electrode. Sodium chloride is separated as it accumulates from the liquor which on cooling yields crystals containing 98-100 per cent ammonium chloride when air-dried. In a second example zinc is added to the solution to be evaporated at the rate of 10-20 gms. per litre either as metal or as neutral zinc chloride.

Title: Improvements in or relating to double cylinder lock
IPC: E05B9/10
Filed: 1962-02-20
Abstract: 990,987. Locks. VIRO INNOCENTI S.p.A. Feb. 20, 1962 [Feb. 24, 1961], No. 6602/62. Heading E2A. A double cylinder lock comprises a locking bit 7 positioned between coaxially mounted cylinders 2, 3, two coupling members 12, 13 associated respectively with loading springs 22, 23 and displaceable in guideways 10, a slot 9 being formed in the boss 107 of the bit 7, so that on insertion of a key 15 into the keyslot 14 a coupling member is brought into engagement with the slot 9 and the lock may be turned. On withdrawing the key the coupling member remains engaged in the slot 9, as it is only stressed by the loading spring when the key is in the fully inserted position, and is pushed out of the slot 9 only by insertion into the slot 9 of the other coupling member on the opposite side. In a modification, one of the coupling members, e.g. on the inside of a door, is permanently biased against the boss 107 by springs inserted in the guideway 10, this force being less than that exerted on the opposite side when the opposite key is in its fully inserted position. In this case the key directly engages the coupling member.

A direction signalling system for vehicles of the type wherein lights 12 or 13 on the side to which a turn is to be made are flashed by contacts 6 or 7, respectively, controlled by cams 8, 9, driven by an electric motor 5 is operated by a single pole two-way switch 2. When switch 2 is moved from its central neutral position to the selected side, connecting battery 1 to contact 3 or 4, a relay winding 17 or 18, respectively, is energized and attracts the common armature 16 which closes contacts 15 to start the electric motor 5 rotating cams 8 and 9, thereby flashing the lamps on the selected side of the vehicle. An indicator lamp 14 is connected between the two sets of signal lamps and is of sufficient resistance to light when either set of lamps is operated without causing the undesired lamps to light.
