Title: Improvements in or relating to internal-combustion turbines
IPC: F02C7/18
Filed: 1941-05-14
Abstract: 585,334. Gas turbines. GRIFFITH, A. A. May 14, 1941, No. 6209. [Class 110 (iii)] In a gas turbine, air, which is taken from the delivery of the air-compressor for supplying to end-thrust balancing devices and, for use as a cooling medium, to bearings &c. is cooled by heat interchange with the fuel oil. A heatexchanger is located in the space between the diaphragm 28 and a cover 27. Air from the compressor delivery enters by ports 30 and after traversing the heat-exchanger passes into the hollow shaft 10 for distribution. Fuel oil passes along a pipe 24 within the hollow shaft and enters the exchanger through ports 32, leaving it by passages 33 on its way to the burner. The heat-exchanger is made up of a number of nested cylinders and, in an alternative, of a number of associated discs. As the fuel oil and the circulating air are at the same pressure, light constructions may be used. Specifications 585,330 and 585,332 are referred to.

Abstract: 135,404. Meyer, E. M³ller-, March 15, 1919. Hinges readily separable about hinge pin; hinges arranged to act alternatively at either side of door, flap, and the like.-Hinges for doors, windows, &c. of the kind allowing opening from either side and also serving as fastenings comprise a spring-controlled pivot head on the fixed member automatically engaged by an eye or seat in the movable member, in conjunction with a separable pin-and-groove connexion between the members, and means for maintaining the pin in engagement with the groove and permitting intentional disengagement. Figs. 2 and 4 show hinge members 1, 8 intended to be recessed into the hinged members. The fixed member 1 is provided with a spring plunger 5 formed with a conical head 4 for engagement with a conical eye 9 in the movable member 8. A pin 12 on the member 1 en. gages in a groove 10 in the member 8 concentric with the eye 9. The pin 12 enters the groove 10 at the gap 11, and is normally not fully in register with the gap. To release the hinges on one side of the hinged member, a slight sliding movement of the hinged member towards the opposite hinges is necessary, to bring the pins fully into registry with the gape; at the same time, disengagement of the pins of the opposite hinges is prevented by means of extensions 10<1> of the grooves. Engagement of the eye 9 with the head 4 is facilitated by providing a recess 16 between the eye 9 and the gap 11. Fig. 5 shows a butt hinge having the movable member 19 engaging between the parts 23 of the fixed member. Each part 23 is provided with a spring plunger 28 and a groove 30 for co-operation with corresponding recesses 18 and pins 21 on the member 19, without lateral displacement of the hinged member. The pins 21 are retained in the grooves 30 by means of spring tongues 31 which are attached by screws to the sockets 22 of the parts 23 and form yielding catches at the entrances to the grooves; the ends of the spring tongues may be bent as shown at 31<1>. Fig. 10, to engage over the pins at the initial part of the turning movement of the hinge. Fig. 13 shows a similar construction in which the tongue 31" is integral with the socket and has a springy end 31<a>, and it is necessary to displace the hinged member laterally to register the pin 21 for engagement and disengagement.

Title: Improvements relating to operating mechanism for the windows or wind-screens of motor & the like vehicles
IPC: E05F11/38
Filed: 1926-03-11
Abstract: 256,173. Ternstedt Manufacturing Co., (Assignees of Archer, T. P., and Edgar, F. M.). July 29, 1925, [Convention date]. Vehicle-window opening and closing apparatus.-Relates to motor and like vehicles having a vertically adjustable front window or wind-screen c, the upper edge of which moves in a pocket or header b in the hood and in which the manual effort exerted on the operating handle h is transmitted to the windscreen through gearing or mechanism giving a relatively large mechanical advantage. In order to prevent any operating effort being transmitted in increased force to the later elements of the gearing after the screen has reached its extreme position, with the possibility of causing stripping of the teeth or other breakage, stops arranged on the earlier elements of the gearing are adapted to come into engagement as the windscreen reaches its extreme positions and thereby resist the operating effort at a stage where no mechanical advantage has been derived or where the operating effort has not been stepped up to its final condition. The invention is described as applied to a gearing of known type comprising at each end of the header pins n, q on crank-arms m, p engaging loops on the upper edge of the windscreen, the crank-arms being attached to wheels k, o having intermediate driving-gear j, i<1>, g and s, as shown, and the gears being interconnected by a toothed rack r. The stops which are adapted to come into engagement at the predetermined points consist of a projection u on a disc t attached to the same spindle as the driving pinion g, and a co-operating stamped-up stop w on the intermediate wheel i'.

Title: Improvements in Intercommunication Telephone Systems.
Inventor: DUNGEY JOHN WILLIAM
IPC: H04M9/00
Filed: 1916-05-16
Abstract: 102,786. Dungey, J. W., and Kersting, C. B. May 16, 1916. Intercommunication systems and apparatus.- In an automatic system of the kind described in Specification 22549*/14, the selector switch is controlled by a solenoid in a local circuit which is wholly or partly controlled by the removal and replacement of the receiver. In the arrangement shown in Fig. 1, the selector arm 3 is operated by a solenoid S, the circuit of which contains three switches 21, 23; 24, 25; 26, 27. If a call is initiated at the station shown, when the receiver is removed from its hook 10, the circuit of the solenoid S is made by the closure of the switch 26, 27, and the arm 3 is moved to its limiting position when a projection K breaks the circuit of the solenoid at the switch 21, 23 and establishes the circuit of a hold-on magnet M at the switch 21, 22. If the station shown receives a call, the circuit of the solenoid S is made at the switch 26, 27 when the receiver is removed from its hook 10, and the arm 3 moves over its contacts until the calling-line is found, when the energization of the line magnet E operates its armature 18 to arrest the arm 3 and to break the circuit of the solenoid S at the switch 24, 25. In a modification, the circuit of the solenoid S is controlled by an independent switch. In the modification shown in Fig. 3, the selector arm 3 is normally held in its initial position by a latch CH, from which it is released when the receiver is removed from its hook 10. When a subscriber is calling, the arm 3 moves to its limiting position against the action of a retarding-device; but when a subscriber is called, the arm 3 of his selector moves until it is arrested by the energization of the magnet E. The circuit of the solenoid S contains two switches 28, 29 and 30, 31. When the receiver is removed from its hook, the switch 30, 31 is opened, and when the arm 3 has moved through a predetermined angle, the normally open switch 28, 29 is closed, in order that the restoring-solenoid S may be energized when the switch 30, 31 is closed by the replacement of the receiver. In the modification shown in Fig. 4, the selector arm 3 is moved quickly to its limiting position by the action of the solenoid S, when its circuit is made at the contacts 37, 38 by the removal of the receiver. At the end of its travel, a projection P engages a lever T to break the circuit of the solenoid at the contact 39. The arm 3 moves slowly back under the action of a spring SP until arrested by the energization of the magnet E in the case of a called subscriber, or back to its initial position in the case of a calling-subscriber. The lever T is returned to its normal position to engage contact 39 when the receiver is replaced.
