Abstract: 481,573. Clip - fastenings. FERNBERG, E. B. Sept. 11, 1936, No. 24795. [Class 44] The invention provides various clips of modified U-form for securing a trim pad to door and body frames of motor vehicles, one limb being adapted for location in or securing to the pad and the other serving to secure the pad to the support. Fig. 1 shows a simple form in which a straight limb 20 is passed through a slot in the pad 11 and is located by a corner 21, the other limb 18 having a bent up end 19 providing a flared mouth to facilitate engagement with the support, not shown. In Fig. 2 the limb 18 is bent back at 30 to bear against the rear face of pad 11, whilst in Fig. 7 limb 18 is bent in the opposite direction at 47 for the same purpose. Fig. 3 shows at 37 a Z-formation of limb 20 which fits a rectangular aperture in the pad. Fig. 11c shows a clip applicable to the edge of the pad, the upturned end 75 biting into the pad, whilst lateral displacement of the clip is prevented by its location in a notch 76 in the edge of the pad. In Fig. 14 the lower limb has a part 94 fitting the aperture 97 in the pad, a tongue 98 engaging the front face of the pad, and a rounded portion 96 co-operating with the end 19 to give a lead in engaging the clip with the support. Fig. 15b shows a clip secured to the rear face of the pad by a separate member 111 having prongs which may be clinched. Modifications of the above forms of clip are described. The clips may be of sheet-metal, wire, or other material such as compressed fibre. Specification 472,532 is referred to.

Abstract: 1,040,224. Vacuum pans; sugar massecuite. PATRICK MURRAY (PROPRIETARY) Ltd. June 11, 1965, No. 24891/65. Heading B1B. In a vacuum pan, suitable for boiling sugar massecuite, the massecuite is heated in, and flows upwards through, the vertical tubes 16 of a steamheated, floating calandria supported from the side walls 5 of the pan by circumferentially spaced tubular members 9 which constitute air-jacket casings for the steam inlets 10 and for the spent steam and incondensible gas outlets 11 which are thereby insulated from direct heat transfer with the massecuite flowing down the annular space between the walls of the pan and the calandria. The tubular members 9 are preferably of vertically streamlined cross-section, e.g. elliptical. Steam condensate is discharged from the calandria through pipe 19 projecting through the bottom tube plate. A plate 12 extends across the calandria in line with the axes of outlet pipes 11. Perforated baffles 13 form steam discharge spaces at the outlet pipes 11. The calandria is provided with spaced double walls forming an annular jacket 14 through which air circulates by convection via apertures 15 in tubular members 9. Also described is a vacuum pan having a floating calandria divided by vertical circular walls into a circular inner tube zone surrounded by two annular tube zones, each zone having its own steam inlet and outlet pipes. The outer annular jacket of the calandria is maintained under the same sub-atmospheric pressure as the interior of the pan.

Title: Manufacture of symmetrical di-(arylamino)-hydroxybenzenes
IPC: C07C215/82
Filed: 1933-09-11
Abstract: Symmetrical di-(arylamino)-hydroxybenzenes are manufactured by heating one molecular proportion of phloroglucinol with about two molecular proportions of an aromatic amine, if necessary in the presence of a diluent, e.g. xylene, at about 140 DEG  C. in such a manner that the water formed during the reaction distils from the reaction mixture.  The products are intermediates for the manufacture of dyestuffs.  Examples describe the reaction of phloroglucinol with p-chloraniline, aniline, o-and p-toluidine, p-anisidine, m-xylidine (CH3 : CH3 : NH2=1 : 3 : 4), b -naphthylamine and m-nitraniline.  In the last case a small quantity of the monoarylaminodihydroxybenzene is obtained as a by-product.

In the apparatus shown liquid enters stage 19 at 22 and is pumped by 18 through pipe 24 to 19'. Fresh gas enters 19' through pipe 25; the gas/liquid mixture passes down channel 12, undissolved bubbles rising outside channel 12 to chamber 14 whence the part-used gas is transferred through pipe 16 to stage 19. Used gas is exhausted from stage 19 at 29; liquid may be recirculated from 19' to 19 through pipe 28, while treated liquid is removed from 19' at 26. In Fig. 2 (not shown) there are depicted three treatment stages to which liquid is supplied in parallel and gas in series, together with a final stage (2') from which gas is not recovered, and two additional treatment stages in parallel from which also gas is not recovered. Fig. 3 (not shown) depicts a three stage apparatus in which the riser channel is separate from the downflow instead of surrounding it, together with a pre-treatment degassing stage (20). Figs. 4-7 (not shown) depict arrangements of gas inlet tubes 3. The method and apparatus may be used in the treatment of waste-water with pure oxygen or in the manufacture of yeast.

A semi-conductor device includes a first conductive casing part having mounted thereon a disc, which supports a semi-conductor element having two flat surfaces and supporting another disc, a second casing part which is bellshaped, is mounted on the first casing part and is provided with an insulating portion having an opening therein through which an electrical conductor having an abutment larger than the opening passes in a sealed manner and makes contact with the other disc and a spring between the insulating part and the abutment. In a specific embodiment, Fig. 2, a controlled power rectifier is shown having an NPNP- silicon rectifier 18. Copper casing 1 has a malleable disc 4, e.g. of tin, separating it from the rectifier 18 upon which is placed a malleable disc 16 and ring 17, e.g. of tin, together with a cylinder 22 of insulating material. Where the NP zones meet under the cylinder 22 a surface coating of SiO 2  is provided to ensure good insulation. An abutment 14 and ring 19 are provided on top of the malleable disc and ring whilst springs 7 and 20 hold the assembly in place. The lower surface of 14 and the upper surface of 1 are lapped to ensure good contact with discs 4 and 16, the surfaces are also nickel and gold-plated. An electrode 3 having incisions 13 to allow for thermal expansion, passes through insulating material 12 which also accommodates another electrode 21.
