Headings BIT and B2P [Also in Division F1] Exhaust gasses pass through a centrifugal separator P Fig. 1 and then flow into at least one further separator F1 comprising an expansion chamber 10 and a filter 13. The gases enter separator P tangentially, the whirling flow causing separation of coarse water droplets and soot particles through a perforated tube 3. The partially purified gases flow through pipe 8 into expansion space 10 from which some gases flow through perforated wall 11 into filter chamber 13 whilst the remainder flow through pipe 18 into a second expansion and filter device F 3  from which a portion of the gases flow directly to the outlet through pipe 19. Filter chambers F 2 , F 4 , are situated downstream of devices F 1  F 3 , and the gases from the filter compartment of device F 1  flow through the filter chambers of devices F 1  - - - F 4  in series. The separated material in device P settles in chamber 21. In Fig. 4 (not shown) the pipe 19 is omitted and all of the gases pass through the final filter chamber (F 6 ). In Fig. 15 the filter chambers F 1  --- F 6  are formed in a perforated member 25 loosely fitting in the outer casing 12', vibration of the member 25 during operation causing deposits to be shaken out of the filters into collecting chambers 23. Separate collecting chambers may be associated with each filter compartment and these chambers may be connected by pipes to a sludge collecting tank in which noxious gases dissolved in the sludge may be neutralized by material such as sodium carbonate, lime or sulphuric acid. Catalyst material may be incorporaed in the filters. 1,160,392. Screening apparatus. L. W. JOHNSON. 12 Oct., 1966 [25 April, 1966], No. 45569/66. Heading B2H.

Title: Manufacture of axle casings such as incorporate a differential gear
Inventor: OWEN ERNEST WILLIAM BEECH
IPC: B21D53/90
Filed: 1952-03-04
Abstract: 717,527. Vehicle axle casing. RUBERY OWEN & CO., Ltd. Feb. 27, 1953 [March 4, 1952], No. 5604/52. Class 79(4) [Also in Group XXII] A banjo-type of axle casing is made from two half-components welded together along their longitudinal edges, each half-component being formed from a strip of sheet metal, bent to form a central portion of semi-circular longitudinal cross-section between straight end portions and formed to a longitudinal channel shape of semi-circular crosssection at the ends and rectangular cross-section at the centre, triangular gusset plates being welded between adjacent edges of the portions of the assembled half-components intermediate the centre and the ends, which gusset plates may be welded onto the strips prior to their being shaped. A rectangular strip 11 of sheet metal first has its central portion 12 bent out of alignment with the ends portions 13 to be semi-circular in longitudinal cross-section, the thus bent strip is then longitudinally channelled, the central portion to rectangular cross-section and the ends to semi-circular cross-section with the portions between the centre and the ends changing from rectangular to semicircular section. The two operations may be carried out on a cold strip or on a heated strip in which latter case they may be effected simultaneously. The half-component is then treated, e.g. by stamping, to correct the form produced, this treatment serving to give the half-component two inclined edges 18, Fig. 3, which leave a V-notch when the edges of the end portions of two opposed half-components are welded together, as at 19, Fig. 4. Gusset plates 20 of substantially triangular form are welded in said notches. Such plates may be welded to an internal baffle 22, Fig. 5, preferably bell-mouthed towards the ends of the casing, or may be formed integrally with the baffle. The blanks 11 may be of reduced width towards their ends. Two or four triangular gusset plates 20 may be welded to the edges of each strip 11 prior to the forming of the half-components, in which case, and when the gusset plates are formed integrally with the baffle, the formed half-components may be blanked to avoid the use of a sharp-point V-gusset. For heavy casings the semi-circular sectioned ends of the half-components may be held between mating dies and the edges bevelled.
