Title: Improvements in or relating to Gas Analysing Apparatus.
IPC: G01N1/00
Filed: 1918-08-01
Abstract: 118,114. Akticbolaget Ingeniorsfirma F. Egnell. Aug. 1, 1917, [Convention date]. Gas analysis. - In gas analysis apparatus in which the gas-supply is diverted to different analysers, or different gas supplies are passed through the same analyser, the turning of a cock or valve for these purposes is effected automatically by the action of the pressure medium of the gas pump on a piston. In the arrangement shown in Fig. 1, in which a cock k connects one or other of two gas analysis apparatus M', M<2> with a pumping device of the kind described in Specification 16561/08, a branch y of the pipe h which supplies compressed gas for operating the pump is connected to a cylinder x in which works a piston w attached to a rod s carrying a pawl l and a stop r. A spring z urges the rod s towards the left, but is held inoperative by a stop q on the armature p of an electro-magnet n in a circuit which includes the mercury in a and a contact rod l in b. When the circuit is complete, the armature is attracted, thus allowing the spring z to push the rod s to the left, in which motion the pawl t acts upon a ratchet u on a shaft v and operates the cock k mounted on the same shaft. When the pressure in y rises, the piston w is driven to the right, thus compressing the spring z and allowing the armature to return on the breaking of the circuit. In the arrangement shown in Fig. 2, the electro-magnet is replaced by a second piston 7 operated from a branch pipe 5 on the pipe y. This piston carries a tappet 8 adapted to push a roller 12 on a lever 9 pivoted at 10 in opposition to a spring 11 so as to take a detent 13 out of the path of the end 14 of a lever 2 carrying a pawl 3 engaging the ratchet wheel u When the pressure rises after the actuation of the piston 7, the piston w rises moving the lever 2 against the spring 4. In the arrangement shown in Fig. 3, the pumping apparatus consists of vessels a, 18, supply pipe 15, and siphon 16. Rise of the pressure operates a piston 29, rod 28, ratchet wheel 27, shaft 26, and cock 23 which puts one or other cf the gas supply pipes P', P<2> into connexion with the measuring vessel M<1> of a gas analysis apparatus, the inlet pipe 22 dipping into a liquid seal 21' in the vessel M<1>. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the invention for effecting other operations, such as the setting in action of a registering device and also the use of a flexible diaphragm or of a float for obtaining the required movements. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in machines for securing two-part rivets in pieces of leather or like material
IPC: A41H37/10
Filed: 1931-05-01
Abstract: 368,581. Setting two -part rivets. DAUDE, G. E. GOBIN-, 19, Rue Beranger, Paris. May 1, 1931, No. 12843. Convention date, May 3, 1930. [Class 43.] In machines for securing pieces c, d, of leather or like material, by two-part rivets a, b, supplied from separate distributers 3, 4, respectively, to opposite sides of the material, the parts b are fed to the required position by a reciprocating slider 14 whereon they are deposited, teeth 24 on the slider causing the parts b to move with it as it moves in one direction, and a series of pivotally mounted. plates 27 preventing movement of the parts b with the slider as it moves in the opposite direction. The machine comprises a column 1 with a head 2 and a horizontal arm 5 bearing a block 6 wherein an anvil 7 is vertically slidable. An operating-lever 8 is pivoted about a shaft 9 and is reciprocated by link-andlever mechanism 39, 40, 41, 42, 43, 45 driven from a shaft 33 by a crank disc 35 and connecting-rod 38. A connecting-rod 37 operates. a riveting-punch 12. Runways 10, 13 lead from the distributers 3, 4, respectively, and are provided with shutters 11, 16. The runway 10 guides parts a directly to the punch 12. Parts b are fed from the lower end of the runway 13 to the anvil 7 by the slider 14 mounted between guide-bars 17 in a slideway 15. The slider 14 is normally urged by a spring 18 towards a lever 19 pivoted at 20 and bearing a short arm 19a operated by the lever 8. The slider 14 has an inclined surface 22 terminating in a nose 23 and carries on its upper surface pairs of the teeth 24 and two pins 25. The guide-bars 17 are cut away as at 21 so that the parts b may fall from the runway 13 on to the slider 14 into a position in front of the pins 25. When the slider is moved forward in a direction Z, Fig. 10, by the action of the levers 8, 19, the parts b pass under the spring-controlled pivoted plates 27 which retain them in a forward position when the slider 14 n.oves back. Parts b are thus progressively fed by the conveyer and are finally pushed by the nose 23 under a spring- controlled member 31 through an aperture on to the anvil 7. The mechanism is so arranged that the anvil rises on receipt of a part band the punch 12 falls with a part a, and the parts are riveted together to join the pieces c, h.

Title: Improvements in and relating to automatic electrical cut-outs
IPC: H01H71/24
Filed: 1924-05-26
Abstract: 231,040. Adams, E., and McAnulty, A. H. May 26, 1924. Cut - out arrangements; electromagnetic switches.-An automatic cut-out device for isolating a polyphase motor (for example, a threephase motor) comprises two three-way switches 25, 27, 29 and 26, 28, 30, with the arms of the respective switches in the same phase electrically connected together at the common pivots 22, 23, 24, one of the switches being closed and maintained closed by an electromagnet 35 connected across one of the phases and the other closed and maintained closed by an electromagnet 34 connected across a different phase. To supply the motor the hand-operated switches 39, 47 are closed, thereby connecting the operating winding 34 across the line wires 14, 15 and closing the right-hand, three-way switch. This supplies current from the line wire 13 to the pivot 22 and from the line wire 15 to pivot 24 and completes the circuit of winding 35 across the line wires 13, 15 thereby supplying the motor. If a fault occurs on either of the lines 14, 15, the energization of winding 34 falls off so that the spring 51 is able to open the right-hand switch, and the left-hand switch opens in consequence. If a fault develops on either of the lines 13, 15, the spring 42 causes the opening of the left-hand switch so that the motor is isolated in the event of a fault on any line. The arrangement may be adapted to a number of phases more than three.
