Class 99(1) In a pipe joint containing, resilient material, such as rubber, to effect a seal 5, Fig. 1, between the two halves of the joint, the seal 5 being carried by an encircling holder 4, the latter is surrounded by a space to which fluid in the pipe has access so that the holder 4 is exposed to and protected by the fluid from the direct effect of heat to which the outer part of the joint may be subjected. A carrier 3 on the pipe 1 houses the holder 4, the seal 5 in which bears upon a spherical part 6 secured to another pipe 2; the pipes are connected by a nut 7 engaging threads on the carrier 3. The holder 4 and seal 5 are cooled by the water flowing in the pipes, as indicated by the arrow 8, whilst an insulating plate 10 which may also serve as a seal is interposed between the nut and holder to prevent heat reaching the seal 5 from the nut 7 or via the gap 9 between the holder 4 and part 6. Holes 11 and 12 enables water to cool the interior of the part 6; further holes may be provided near the extremity of pipe 2. In a modification an axially and angular adjustable joint comprises a sleeve 21, Fig. 3, on a pipe 20, the sleeve 21 supporting the holder 22 so that it may slide therein, the latter housing the seal 23 engaging the other pipe 24; the pipe 24 has the spherical part 25 fixed thereon against which bears a correspondingly shaped flange 26 secured by bolts (not shown) to an axially movable flange 27 abutting the sleeve 21.

Abstract: 662,889. Pressure relieving devices for fluids. PLATERS & STAMPERS, Ltd., and HORNER, H. May 18, 1950 [May 19, 1949] No. 13442/49. Class 135 A pressure relief plug for a pressure cooker &c. comprises a resilient member 1 mounted in an opening 3 in the cooker lid and having a stepped aperture 8, and a fusible closure member 9. The member 9 is movable under normal pressure in the cooker to cause a portion 10 to seal the aperture, and under a predetermined excess pressure to force the portion 10 through the aperture to release the pressure. A foot 13 prevents the member 9 being detached from the member 1. If the aperture is obstructed, the entire plug will be expelled from the opening 3 at a slightly higher pressure than said predetermined pressure, and an undue rise of temperature causes the member 9 to melt and release the pressure in the cooker.

A process of electrodepositing an alloy of copper and tin comprises passing an electric current from an anode to a cathode through an electrolyte having a pH value of from 6.5 to 10.5 and containing dissolved therein a soluble alkali-metal cuprous complex, a soluble alkalimetal stannous complex, an excess of alkalimetal pyrophosphate, a polypeptide and an alkali-metal orthophosphate. The alkali-metal radical may be replaced by the ammonium radical. The word " polypeptide " is intended to include proteins, amino acids, glue and gelatine. The cuprous complex may be formed from a cuprous salt dissolved in potassium cyanide, and the stannous complex from a stannous salt such as stannous sulphate, chloride, or pyrophosphate, dissolved in potassium pyrophosphate. In the process separate anodes of tin and copper are preferably used, although an anode of tin and one of tin-copper alloy may be used. As an example of the process, a basis metal is immersed in a bath consisting of from 8 to 300 grms. per litre of a pyrophosphate compound selected from ammonium, potassium, and sodium pyrophosphates, from 2 to 230 grms. per litre of a soluble cuprous compound selected from cuprous cyanide and halide, from 2 to 350 grms. per litre of a cyanide selected from ammonium, potassium, and sodium cyanides, from 2 to 50 grams per litre of a soluble stannous compound selected from stannous chloride, pyrophosphate and sulphate, from 5 to 120 grms. per litre of an orthophosphate compound selected from ammonium, potassium, and sodium mono-, di-, and triorthophosphates, from 0.01 to 5 grms. per litre of protein selected from glue and gelatine, and water. A current is passed through the bath, in which there is a potential drop of from 0.5 to 2 volts between the anodes, the copper anode to cathode voltage being from 2 to 3 volts and the tin-containing anode to cathode voltage being from 0.1 to less than 2 volts.

Abstract: 1410458 Microwave filters WESTERN ELECTRIC CO 2 April 1974 [4 April 1973] 14454/74 Heading H1W [Also in Division H3] A planar microwave resonator comprises a rectangular conductive area 11 forming part of a printed circuit and capable of supporting two orthogonal standing waves. As shown, coupling lines 15, 16 aligned on the orthogonal bisectors of the rectangular resonator and capacitively coupled thereto, excite waves having directions of propagation respectively l 1 , l 2  associated with resonant frequencies # 1 , # 2 . The lines 15, 16 are mutually decoupled since each is situated at the node of the standing wave excited by the other. Line 17 situated at the corner 23 of the rectangle, will, however, couple to both waves. In the circuit shown in Fig. 5, lines 52, 53 are inductively coupled to the adjacent corners 54, 55 and both excite orthogonal waves at frequencies # 1 , # 2 , these waves being in phase. If the frequencies are close to each other, the circuit provides a bandpass filter having a bandwith equal to 2(# 1 -# 2 ). In the circuit of Fig. 6 (not shown), the coupling leads are situated at diagonally opposite corners whereby waves at frequencies # 1 , # 2  are excited in antiphase and the circuit provides a notch filter.
