Title: Improvements in and relating to solder for use in the jointing of pipes
Inventor: JONES SYDNEY HERBERT
IPC: B23K1/20
Filed: 1961-05-03
Abstract: 994,410. Making solder strips; soldering; Shearing. KAY & CO. (ENGINEERS) Ltd. April 13, 1962 [May 3, 1961], No. 16019/61. Headings B3A, B3R and B3W. A strip of solder for use in joining pipes is cut to length and secured to a backing of thin sheet material by gum or adhesive, to be peeled off and adhered to a part to be joined. A roll of paper is passed between rollers which press a longitudinal channel therein and flux cored solder from a reel is passed, after flattening between rollers and coating with gum or adhesive, with the paper through rolls which press the solder into the groove. Alternatively the paper may be coated with gum or ahesive. The assembly is passed between a backing roller with a resilient surface and a cutter roller having radially projecting cutters embedded in resilient material to cut the assembly into lengths. The gum or adhesive may be a flux and the backing may be treated with silicone to prevent running of the adhesive. Strips of solder are peeled from their backings and pressed into circumferential grooves at the ends of a tubular coupling member and pipe ends are placed over the coupling for soldering. A plurality of solder strips may be adhered to a single backing sheet.
Patent GB-636223-A (GB)
Title: Improvements relating to apparatus for producing artificial reverberation effects
IPC: G10K15/10
Filed: 1947-06-18
Abstract: 636,223. Telephonic reverberation systems. JONES, E. W. BERTH-. June 18, 1947, No. 16026. [Class 40 (iv)] In one arrangement, Fig. 1, signals from a transducer 12 pass through an amplifier 13 to a recording electromagnet 5, where they are superimposed on a high-frequency biassing current from a source 14 and recorded in a layer 2 of magnetite or thin steel on the edge of a non-magnetic disc 1 driven in a clockwise direction by a motor 4, or in a closed loop of magnetic tape or wire. The recorded signals are picked up by reproducing electromagnets 6 to 11 in succession and fed through attenuators 15 to 20 to an amplifier 21 whose output is combined with the original signals from the amplifier 13, so that the output 22 of the apparatus provides the original signals with artificial reverberations added. Alternatively, one of the reproducing electromagnets, preferably 6, instead of the amplifier 13, may provide the original signals to the output 22. The attenuators 15 to 20 are so arranged that the signals from devices 6 to 11 have progressively decreasing amplitudes, and may also be arranged to attenuate signals of some frequencies more than others. After each revolution the recorded signal is partially erased by the high-frequency flux produced at 5 by the biassing current from the source 14, or by an erasing electromagnet disposed between 11 and 5, and the record is effectively erased after about six revolutions. In a second arrangement, Fig. 2, highfrequency biassing current is fed from a source 29 to an erasing electromagnet 26 and also to a recording electromagnet 27 via an attenuator 30. The recording electromagnet 27 also receives, via an amplifier 32, signals from a transducer 31 which are recorded on a magnetic tape or wire 23, wound from reel 24 to reel 25, and picked up by a reproducing electromagnet 28. The signals are then fed through an amplifier 33 to the output 34 of the device, which may be fitted with a filter 36. The output of the amplifier 33 is also fed back through an attenuator 35 to the amplifier 32 and thence to the recording electromagnet 27. Thus each signal is repeatedly re-recorded and reproduced with successive reductions of amplitude until it no longer produces a signal in the electromagnet 28. Specification 526,984 is referred to.

A method of making a composite bearing strip comprises placing a layer C<SP>1</SP> of commercially pure aluminium on a steel backing strip A and bonding them together by heat and pressure, depositing a second layer G<SP>1</SP> of comminuted tin and aluminium and sintering by heat and compression to densify the comminuted layer and also to strengthen the bond between layers. In a preferred embodiment low carbon cold-rolled steel strip which has been chemically cleansed and electro-plated with nickel is drawn from a coil A and passed through flattening rolls B. An applicator C deposits a layer C<SP>1</SP> of comminuted commercially pure aluminium on the nickel surface, which is sintered in an electric furnace D having a non-oxidizing atmosphere at 1150‹ F. The strip then passes through heated rolls E to densify the sintered layer and increase the strength of its bond with the backing strip and a wire brush F removes the oxide film therefrom. A second applicator G deposits a layer G<SP>1</SP> of mixed aluminium powder and tin, preferably containing from 10 to 20 per cent of tin and the strip passes through a second electric furnace H having a non-oxidizing atmosphere where it is heated to 400‹ F. and remains for 20 to 30 minutes. The strip then passes through another set of rolls 1. The aluminiumtin powder may also contain small quantities of iron, copper, lead, nickel, silicon, magnesium, manganese, antimony or zinc, and this powder may have its constituents thereof in separate particles or it may be a powder of the alloy. The pure aluminium layer may alternatively comprise an aluminium strip which is bonded directly to the nickel-plated surface of the steel backing-strip.
