Abstract: 1281561 Moulding clay gulleys ELLISTOWN PIPES Ltd 7 Jan 1970 [8 Jan 1969] 1087/69 Heading B5A [Also in Division E1] An extrusion moulded clay gulley trap comprises an asymmetrical D-shaped gulley socket end 17 (which receives a plastics or metal grating 23 having a down-pipe cut-out 24) merging at a tapered, asymmetrical section, hopper 18, into a short symmetrical straight length 19 (which may be omitted), followed by a symmetrical trapped bend 20, and terminating in a symmetrical short straight portion 22. The asymmetrical portions 17, 18 are moulded by extrusion through an annular orifice 2 into a cavity 5A, 5B defined between an outer hingedly openable outer mould portion 6A, 6B, and an inner mould portion 8A on a vertically reciprocable table 7, the larger volume portion 5A of the cavity being filled in the same time as the smaller volume portion 5B by restricting the flow to the latter through the orifice 2, by pivotal movement of a circular flow deflecting plate 11 on shafts 13 rotated by a handle 12. After opening and removing the mould portion 6A, 6B, the table 7 is lowered with the plate 11 centrally disposed to extrude the straight section 19, and the bend 20 and straight length 22 are then formed after lowering away the mould portion 8A on table 7 to enable the sections 19 and 20 to swing away, by appropriate manipulation of the plate 11 and table 7 during further extrusion, followed by severing of the moulded gulley from the die.

Abstract: 157,378. Chemische Werke vorm- Auerges, (formerly Ges f³r Verwertung Chemischer Produkte). Nov. 28, 1919, [Convention date]. Coating non-metallic surfaces with metals.-A reflecting surface of copper is produced on the inner surfaces of the walls of vacuum-jacketed vessels by introducing the copper-plating solution to the space to be evacuated, washing out and drying, and then evacuating the space while the vessel is heated. During the heating process a reducing gas or vapour such as hydrogen or methyl alcohol vapour is admitted to the space and exhausted therefrom, thus leaving copper surfaces free from oxide. Alternatively, the reducing vapours may be introduced during the drying operation, in which case a neutral gas is admitted during the heating process. The heating process may be carried up to the softening temperature of the glass, or of the glaze in the case of ceramic vessels.

The valve 29 mav also move down to relieve excess pressure on the bv-pass side of the diaphragm by connecting the chamber 13 to the intake side of the pump 1. In another form, the valve relieves the pressure under the diaphragm, but when an excess pressure arises on the by-pass side, it prevents relief until the diaphragm breaks. In another form, the two chambers 13, 16 communicate with opposite sides of a diaphragm or valve which relieves excess pressure in either chamber by breaking or moving.

The cover or covers can be raised and adjusted without affecting the adjustment of the raceways. A front cover 1, Fig. 1, of a raceway J<1> in a double-raceway machine is hinged to a plate 8 adjustabie on the side of the raceway by eccentrics 13*, 14. The eccentrics work on fixed pins 15, 16 on the raceway and are set by handles 17, 20 according to the required height of the cover 1. The cover is fixed in position by a pin 9 entering a slot in a bracket 7. The cover is opened by sliding out the pin 9 from its slot against a spring 10 and pivoting the cover on a rod 4. The rear cover 21, Fig. 3, is set by a pin 28 and slot 29 and spring pivoted to an adjustable plate 27 on the rear raceway. One end of the plate is adjusted by an eccentric 43 &c., and the other end is adjusted by two thumbscrews 34, 35 with round ends which engage a disk 39 eccentrically mounted at 40. The plate is raised by tightening the thumb-screw 35 and loosening 34, and vice versa. The cover 21 has to be moved considerably to the right so that the pin 28 clears a block 31 in order that parts of the machine should not be fouled. A second construction is shown in Figs. 6, 8, and 10. The rear raceway cover, Figs. 10 and 6, consists of a spring-held plate 53 adjustable by screws 61 in a holder 55 pivoted by arms 64, 65 to a rod 66. The rod is held in brackets 70 on the side of the raceway. The plate 53 is prevented from endlong movement in the holder 55 by a pin 59. The holder 55 is positioned by an adjustable inclined plate 74, Fig. 7, engaging' a plate 76 on the bracket 69. The cover is operated by a handle 79. The forward cover 81, Fig. 8, is pivoted to a plate 90 carrying spring bearings 85, 86 adjustable in height for the rod 84.
