Title: Automatic rotary welding machines
IPC: B23K9/028

Abstract: 982,272. Welding by fusion. PREMIER LAMP & ENGINEERING CO. Ltd., and P. J. DONAGHY. Jan. 24, 1964 [Feb. 8, 1963], No. 5148/63. Heading B3R. An automatic rotary welding machine comprises power means for moving a consumable electrode arc-welding head relative to the work and for connecting and disconnecting a variable speed driving mechanism to and from a rotary work-holder, and trip or contact devices in a control system whereby when a start control is actuated the welding operation commences, proceeds and stops according to a predetermined cycle. Actuation of switch A operates a fluid pressure clamp C to-hold the work against the rotary holder D whereupon a support G carrying the welding head is moved towards the work. The support G engages controls E, F in turn which actuate a clutch J, H between the driving mechanism N and the holder D and start the welding arc. When the weld is completed a cam U driven with the holder D actuates a switch M to disconnect the welding current and a switch L to release the clutch, whereupon a further control returns the apparatus to its initial position. The work is earthed through a cooled brush and slipring arrangement. In a modification the clamp C is manually actuated.

Title: Improvements in or relating to submarine electrical signalling systems
IPC: H04L25/08
Filed: 1933-02-21
Abstract: 415,389. Preventing inductive disturbance. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Jacobs, 0. B. ; 20, Hamilton Road, Morristown, New Jersey, U.S.A.) Feb. 21, 1933, No. 5308. Convention date, Feb. 25, 1932. [Class 40 (iv).] In a submarine signalling system employing a sea-earthed balancing cable, the receiving apparatus is coupled to the signalling and balancing cables through two separate channels having different frequency characteristics in such a way that the disturbing currents are only eliminated for the low frequencies at which they are most serious whilst the increase in resistance noise produced by the balancing line at high frequencies is prevented. In one arrangement, Fig. 1, the signalling cable 1 is connected to the equalizer 12 and receiver 13 through one channel comprising transformers 4, 15, amplifier 7 and high-pass filter 9, whilst both the signalling cable 1 and the balancing cable 2 are connected through a second channel comprising transformers 6, 16, amplifier 8 and low-pass filter 10. In another arrangement, Fig. 4, the signalling and balancing cables are separately coupled through a phase equalizer 14 and a low-pass filter 10 respectively, and the outputs of transformers 15, 16, are differentially combined so that the low-frequency disturbances are balanced out. For two-way working, the receiving path is normally connected through but on the arrival of currents over line 20, relays 22, 25, 26, operate to connect up the transmitting path and to short-circuit the input leads to both amplifiers 7, 8. In a further arrangement, both cables are coupled to one channel containing a phase equalizer whilst the balancing cable is also coupled to the second channel containing a high-pass filter. In this arrangement, the balancing may be improved by coupling the signalling cable to a network simulating the impedance of the second channel, and in a similar way the balancing cable in the arrangement shown in Fig. 1 may be coupled to a network simulating the impedance of the first channel. The earth connection 5 may be made to the cable sheaths either locally or at the termination of the sea-earthed cable.

Class 52(ii) A bed settee comprises a seat and a back portion hinged together and control means, independent of the hinges whereby a dedesired relative position of the seat and back may be maintained during part of the conversion. As shown the back 12 and seat 11 are hinged together at each side by hinges 13, 14 each comprising a pair of plates such as 18, 19 pivoted together at 26 and a pair of links 28, 29 connecting them to the base 15. A control rod 33 having end portions 34, 35, 38 of the shape shown is mounted for rotation in the seat portion 11. To convert the settee into bed position the seat 11 and back 12 are rotated anticlockwise causing the seat and back to move somewhat forwardly and the back 12 to rest in horizontal position on a base member 15. The control rod 33 is then turned through a quarter turn which frees the rear end from the back portion 12 and allows the seat portion 11 to be lowered into alignment with the back portion 12 i.e. into bed position the end 34 of the control rod then pointing downwardly and serving as a supporting leg. To convert to settee position the seat portion is raised and the control rod 33 rotated so as to bring its end 35, 38 into contact with the adjacent end of the back portion 12, a stop 40 having an inclined face 40a and a vertical edge 40b being provided on the back portion 12 to cooperate with the end of the control rod. The back and seat portions thus locked together being then rotated to settee position. In a modification a slidable leg portion may be provided and may be connected to the control rod. A pair of control rods operated simultaneously by one handle may be provided.
