Title: Improvements in locking devices for safety purposes
IPC: E05B29/00
Filed: 1934-05-04
Abstract: 437,527. Locks. FUTRAN, S., 40, Alexanderstrasse, Berlin. May 4, 1934, No. 13511. Convention date, Dec. 27, 1933. [Class 44] A locking mechanism has a number of rotatable locking elements which have two unlocking positions ; one is the final unlocking position, and the rotated elements pass through the other during the locking movement in order to remove the check on the movement of the bolt. While this check is removed the bolt is moved to its locking position by the rotation of the key which operates the elements. Each locking disc 4 has two recesses 6, 7 in its periphery for the reception of the end 16 of the pivoted locking member 15, and two recesses 8 in which spring controlled detents 9 engage. The cylinder 2 which supports the discs is rigidly connected to an arm 10 having a pin 11 at its end to operate the bolt 12. An extension 18 on the member 15 has an opening 19 through which the pin 20 on the bolt 12 can pass when the end 16 is in the recesses 6 or 7. The bolt is shown in the open position in Fig. 5. When the key 27, Fig. 4, is inserted in the cylinder 2 and rotated, some of the discs 4 are rotated also and the member 15 is depressed while the end 16 rests on the peripheries of the discs 4. As the key turn continues the arm 10 depresses the plate 24 to release the bolt pin 21 from the slot 22, and the recesses 7 of the rotating discs are brought into line with the recesses 6 of the stationary discs. The spring 17 then raises the member 15 so that its end 16 is in the recesses, and the pin 11 on the arm 10 operates the bolt 12 to its locked position in which the pin 20 passes completely through the slot 19. Further rotation of the key and discs causes the end 16 to leave the recesses and the parts occupy the position shown in Fig. 6 when the key can be withdrawn. In the modification shown in Fig. 10, a number of angular sliding members 31 are operated by the key to cause the points 32 to engage in the slots of selected locking elements 4, which are then rotated by the key. Specification 424,120 is referred to.

Title: Improvements in or relating to the fabrication of disc wheels or the like
IPC: B21D53/26
Filed: 1926-05-31
Abstract: 253,108. Budd Wheel Co., (Assignees of Hughes, J. W.). June 3, 1925, [Convention date]. Wheels.-In making disc and like wheels a shaped sheet is moved by a conveyer through a blanking-press B, a forming - press F, a punching - press P, a drilling - machine D, coining and facing machines to an assembly machine A where a rim is forced on to the wheel. The discs C are carried along a conveyer track T formed of angle or channel rails by means of arms carrying fingers 14, 15 which arms are rocked by cam gear about a shaft S to engage and to release the blanks, the shaft S being moved axially by crank mechanism for feeding. The axial movement of the shaft S at each operation is one half the distance between the centres of adjacent machines. The blanking-press with reciprocated upper die 63 and lower blanking die 62 punches the central hole from the disc and trims the edge. The machine is started by a cam-operated trip mechanism and is stopped with the die in the raised position by a one-revolution clutch. In the forming-press F the blanks are positioned by pins and circularly-arranged tapering blades 90, carried by an upper die head 89, which enter the bed 35 of the press. The lower die 95 contains a centre body 95 which is depressed to a limited extent. When the upper die is raised the centre body is suddenly projected upwardly by compressed air. The, blanks are fed to the punching- machine P along a channel-shaped track, the carrier arms being slotted to engage the upturned rims. The. machine P is actuated through a trip gear and fixing holes are punched around the centre hole in the disc. Leading to the drilling- machine D the track is of channel shape with the upper flange resiliently mounted and grooved longitudinally to prevent rotation of the blanks. The carrier arms are formed with fingers 123, 124 which are closed over the rim by a conical projection when the arm is lowered. The drills are fed downwards to open the punched holes from a cam through an axially-resilient rod. A coining- press, a coin-facing machine, a centre flange finishing machine, not shown in the drawings, then finish off the machined surfaces and the disc is carried to an assembly press A. This latter comprises a turntable rotated at each operation through 120‹ by a Geneva mechanism and carrying three rim sockets into which the rims are placed. These are carried beneath the discs on the track T and on descent of a press head 154 the parts are forced together.

Title: A method for the recovery of water from the exhaust gases of airship motors and apparatus therefor
IPC: B64B1/62
Filed: 1923-05-25
Abstract: 220,986. Parker, H. F. May 25, 1923. Straight tubes between headers. - Water is recovered from the exhaust gas of the internalcombustion engine of an aircraft by passing the gas through a cooler which comprises very long tubes, the gas passing at a rate of between 2¢ and 3¢ pounds of gas per square foot per minute. The length of the tubes is between 600 and 100 times the diameter, which is between 1 inch and ¥ inch. The cooler projects into the air stream, as shown in Fig. 2, which is a section transverse to the air flow; the exhaust, entering by a pipe 1 and a distributing header 2, flows through a number of parallel pipes 3, which are connected by a series of headers 4, and pass through a collector 5 to a box 6 in which the water is condensed. This box, which is similar to that described in Specification 205,191, comprises a number of sinuous plates, troughs being formed at the bends to prevent the moisture from being carried along by the current. The condensed water flows away through a pipe 7. The pipes 3 are connected to the headers 4 by cables passing down the pipes and having tensioning means at the ends; the cables are of a metal having a coefficient of expansion which is about half that of the pipes, which may be of aluminium when steel cables are used. The tubes may be made of fabric by stitching two layers of material together along parallel lines. The two layers may, however, be connected by parallel distance-strips spaced at intervals of between 3 and 6 times their depth; this construction may be stretched on metal tubes which are laced to the longitudinal girders of the airship.

Abstract: 386,976. Rectifying alternating current ; automatic regulation. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) May 11, 1931, No. 13909. Convention date, March 10, 1930. [Classes 38 (ii) and 38 (iv).] Regulation of electric machines is obtained by means of grid-controlled vapour discharge vessels in an arrangement comprising at least two groups of such vessels and a current utilizing element, the direction, value and duration of the current being determined by automatically influencing the grids of the discharge vessels. In Fig. 3, four groups of two discharge vessels form the four sides of a bridge and current is supplied from a transformer to the points 42, 43, the element 33 receiving the current during one half cycle and in one direction, by suitably influencing the grids of one of the pairs of discharge vessels 75, 76, &c. respectively. In an application to the regulation of an electric machine, Fig. 4, a prime mover 46 drives a generator 47 which feeds the network 83, and the exciting winding 49 receives current from the exciter 48 with its two field windings 50, 51. The additional field winding 51 is fed from the transformer 84 through the discharge vessels 60 .. 63. In addition to suitable negative potentials 58, 67, 70, the grid circuits receive alternating currents from the secondary windings 57, 68, 71 respectively, a voltage responsive switch 85 controlling the excitation of the grids. Any rise in the voltage of the generator causes the contact piece 53 to move and put the transformer 56, 57, 71 in circuit, which by exciting the grids, renders the discharge vessels 60, 63 conducting. Current then flows in the field winding 51 in such a direction as to oppose the field in the winding 50, and the voltage of the generator falls. The Specification as open to inspection under Sect. 91 comprises also the replacement of the groups or pairs by a single vessel with a pluralty of emitting main electrodes and the voltage responsive switch is replaced by a phase shifter and torque motor so that either the magnitude or the phase of the voltage applied to the grids may vary to determine the direction of flow of the regulating current. This subject-matter does not appear in the Specification as accepted.
