Title: Improvements in shock absorbers
IPC: F16F9/14
Filed: 1929-05-06
Abstract: 333,274. Gabriel Snubber Manufacturing Co. Jan. 30, 1929, [Convention date]. Fluid-friction vibration-dampers.-In hydraulic shock-absorbers of the oscillating-vane type in which an annular chamber containing the vanes is divided by means of a fixed partition provided with a leak orifice of fixed size, an adjustable leak orifice and a one-way ball valve, the cover is provided with a shoulder fitting to a seat on an extension of the casing and held by a screwed locking ring. The cylindrical casing 1, Fig. 1 and 3, is bolted to the frame of the vehicle and an oscillating spindle 5 carries vanes 7 inside the casing and an operating lever outside. The front of the casing is closed by a cover block 6 carrying one of the bearings for the spindle 5 and secured in position by a screwed ring 34. The outer cover-plate 19 is screwed on to the casing 1 and is formed with a conical part which engages jams on the thin edge of the casing 1 and reinforces it against expansion by the screwed ring 34. The space between the cover block 6 and the cover plate 19 forms an oil reservoir from which oil passes when required into the working chamber through a one-way ball-valve. The partition may be made in two integral parts A with a flange at one end having a hole for a spigot pin B which enters the casing 1 and holds the partition against rotary movement. One part of the partition is provided with a gauged orifice 14 which resists movement of the vanes in an anti-clockwise direction. The other part is formed with a port 10 having a one-way ball valve which opens during anti-clockwise movement and a port 8 of adjustable area which restrains clockwise movement. The area of the port 8 may be adjusted by a plug 9. Fig. 6 shows one construction of ball valve arranged in the partition A2. The ball 11 is forced against a seat in the partition by means of a spring 35, the outer end of which bears against an inturned flange on the end of a cylindrical part 37 which is held in position in the partition by a cross-pin 38. In a modified construction shown in Fig. 7, liquid passes through the port 14<a> and past the ball valve 11 which is then forced off its seat in the partition. When the vanes are moved in an anti-clockwise direction the spring 43 which forces the ball 11 on to its seat is held up by a part 38 which bears against a cross-pin 44, the part 38 being externally of triangular shape as shown in Fig. 9 so as to allow for the passage of liquid. In a further modification the part 13 which supports the spring is made with four projections which screw into the partition as shown in Fig. 4 and 5. Specification 333,214 is referred to.

Title: Improvements in and relating to electric induction furnaces
IPC: H05B6/16
Filed: 1929-05-10
Abstract: 313,044. Northrup, E. F. June 5, 1928, [Convention date]. Induction furnaces.-Leakage of molten metal due to fracture of the refractory wall of the crucible or container causes operation of a protective or warning device inserted in the circuit of a exploring winding disposed on or around the walls of the crucible. The exploring winding comprises conductors 25, 26 non-inductively wound on a cylinder 19 surrounding the refractory container 20. The air-cooled induction coil 20 is separated from the exploring winding by a protective cylinder 18 sufficiently strong and heat resistant to temporarily cheek the flow of molten metal if a fracture occurs in the container. In a modification the winding is embedded in the refractory 20. In a further modification the winding is arranged as a Gramme winding on the cylinder 19 which encloses a crucible, and the induction coil 13 is water-cooled. The conductors 25, 26, Fig. 3, are connected together at one end by a lamp 29 giving a white light and at the other end to current supply leads 27, a lamp 28 giving a red light being fitted as shown. Normally both lamps burn dimly. If a short 30 occurs the lamp 29 is extinguished. If either conductor fuses, both lamps are extinguished. In Fig. 4 the conductor 25 is reversed so that the total resistance of the part of the conductors in circuit when a short occurs is substantially constant wherever the fault may be. The lamps 29, 28 are replaced by a coil 34 and a resistance 32, a second coil 33 being fitted as shown. The coils 34, 33 comprise opposing coils of a differentially wound electromagnet which will cause operation of a visual or audible signal or interruption of the main supply when a fault occurs. In Fig. 6 the winding forms a part 39 of one arm of a Weatstone bridge, the other part of the arm being the coil 40 of an electromagnetic switch 45 controlling a relay switch 51 in the furnace circuit. The red lamp 28 is fitted as shown. The coil 40 may be replaced by the white lamp.

Title: Improvements in and relating to muting devices for signal receivers
IPC: H03G3/28
Filed: 1946-05-15
Abstract: 612,024. Radio signaling; receiving circuits. GENERAL ELECTRIC CO., Ltd., and STENNING, L. C. May 15, 1946, No. 14683. [Class 40 (v)] In a radio receiver provided with means for muting.in the absence of a signal carrier, the time-constant of the muting action is made greater than that for unmuting. Noise in a frequency band above that required for signalling is selected by a tuned circuit 13 in the receiver output and is applied to a rectifier 14 provided with a load circuit 15, 16 of short time-constant. The negative potential developed across the circuit 15, 16 is applied to a valve 17 via a circuit of long time-constant comprising a resistance 18 and condenser 20. With the condenser 20 charged, current in the valve 17 ceases, causing a relay S with contacts S1 to insert an attenuating network 21, 22 in the connections to the loud-speaker. Upon the cessation of noise, the condenser 20 is discharged rapidly over a rectifier 19, causing the valve 17 to become conductive and the network 21, 22 to be removed from circuit. A potentiometer 23 permits of adjustment of the muting conditions. The arrangement is particularly applicable to mobile receiving stations, in which the signal strength may vary greatly over short periods, and may be modified to permit of the selective unmuting of any of a number of receivers according to the transmission of appropriate identification signals. The identification signals take the form of a number of tone frequencies with the omission of those corresponding to, receivers it is desired to call. A further acceptor circuit in the receiver output applies the appropriate tone frequency, if present in the signal, to a rectifier and relay with contacts arranged in series with the anode circuit of the valve 17 so as to mute the receiver. The risk of a signal being missed by a receiver for which it is intended is thus minimized.

Title: Method and apparatus for electric arc-welding
IPC: B23K9/14
Filed: 1947-06-05
Abstract: 649,095. Uniting by fusion. SKYTTE, E. June 5, 1947, No. 14860. Convention date, Feb. 18, 1944. [Class 83 (iv)] In a method and machine for continuous arc welding, a base has a series of angularlyadjustable guide rails, each of which carries a slide having a holder for an electrode whose lower end rests on the work and supports the slide so that when an arc is struck from one electrode to the work the corresponding slide travels by gravity down the guide as the electrode is consumed and when the electrode reaches the end of its travel the holder is oscillated to cause the electrode to engage the next succeeding electrode which thereby forms an are with the work and enables the weld to continue without interruption. The ends of the electrodes which rest on the work are normally insulated therefrom. A number of guide rails 4 pivotally mounted at 17 in insulating bushings 18 in clamps 5 longitudinally adjustable on and secured to a base rail 2, which is carried by a foot-plate 1 resting on the work, serve as guides for slides 6 carrying holders for electrodes 12. The holders are pivotally mounted on the slides so that they may be arranged at the optimum angle with respect to the work, and the adjustment of the desired length of weld per electrode is effected by adjusting the rails on the pivots 17. The electrodes are connected by branch cables 14 to a cable 13. The slides 6 carry angular arms 10 which when the electrode is nearly consumed engage stops 11 on the guide rails about .which they pivot so that the ends of two adjacent electrodes meet and the arc is transferred to the new electrode. The guide rails are provided with notched bars so that the guides may be laterally adjusted to bring the plane of successive electrodes into alignment. The base rail may be mounted on a longitudinal pivot 19 to adjust the plane of the electrodes. Each electrode holder is provided with two countersunk bores of different diameters so that four sizes of electrodes may be used. The Specification as open to inspection under Sect. 91 contained a modification in which the base rail with its guide rails and electrodes was movable along the seam on rollers during welding. In the case in which the base rail was moved on the pivot 19 so as to operate with laterally inclined electrodes on sloping or vertical surfaces the movement of the electrodes was effected by springs or by weights carried by cords over pulleys. This subject-matter does not appear in the Specification as accepted.
