Abstract: 1,094,135. Valves. BONSER ENGINEERING Ltd. Dec. 7, 1965 [Oct. 3, 1964], No. 36050/64. Heading F2V. A relief valve comprises a closure member 11, 12 integral with a stem 21 and biased towards a seat 10 by an adjustable spring 23. Annular discs 36, 36<SP>1</SP> (Figs. 4 and 5, not shown) supported at their outer peripheries engage the closure member and stem respectively and serve to maintain the closure member in axial alignment with the seat. The central hole through the discs is equal in diameter to the closure member or stem and radial cut-outs allow the discs to flex with the closure member so that no relative movement occurs. A rubber or like 0-ring 9 seals the annular space between the neck 6 of the seat and the housing. When the valve is unseated, fluid flows from the inlet 2 to outlets 35 via the discs 36, 36<SP>1</SP> and ports 33, 30. In Fig. 3, (not shown), stem 21 is omitted and the closure member (12) is made hollow to receive a projection 50 on spring seat (48). One disc (36) is provided around the closure member. In Fig. 1, (not shown), the closure member is guided by rubber or like 0-rings 19 engaging the closure member and stem, the rings being arranged to deform with movement of the closure member and not roll.

Title: Method and apparatus for distilling tar and simultaneously producing high and low melting point pitches
Inventor: MCCLOSKEY GREGORY EDWARD
IPC: C10C1/16
Filed: 1930-12-03
Abstract: <PICT:0370387/III/1> Tar is distilled in two stages to produce a low melting-point and a high melting-point pitch respectively, part of the low-melting pitch being distilled further to produce a high melting-point pitch by contact with hot waste gases, e.g. coke-oven gases and these gases being then used to distil the tar to produce the low melting-point pitch.  Gases from part of a battery 3 of coke ovens are collected in a header 7 and passed into a still 10 and then through a tower 11 provided with baffles 17, 18.  Tar is injected through a header 12 and is distilled by the hot gases to form a low melting-point pitch part of which is run off through a pipe 13 to a tank 13<1>.  The remainder is passed through a line 14 into the still 10 where it is further distilled to a high melting-point pitch which is run off through trap 19 and levelling arm 20 to a trough 21 where it is granulated by contact with cold water.  Intimate contact of the pitch and gases in the still 10 is obtained by spraying the pitch into the gases by means of a rotating roll 15.  In a modification the tar is preheated before entering the tower 11 by passing it through a coil in indirect contact with the gases passing off through a pipe 26, the oil content of the gases being thus simultaneously condensed. Specifications 282,826, 284,703, 308,577, [all in Class 32, Distilling &c.], 345,272, 346,753, 347,107, and 347,240 are referred to.
