Patent GB-573487-A (GB)
Abstract: 573,487. Electric insulation. BENDIX AVIATION CORPORATION. July 7, 1943, No. 11064. Convention date, Aug. 28, 1942. [Class 140] [Also in Group XXXV] Ignition apparatus for internal combustion engines such as ignition coils or ignition shielding harnesses in which electrical conductors are enclosed in a casing are filled with a liquid insulating material which may subsequently solidify by a method which includes the preparation by evacuating its interior of a casing containing electrical conductors and having inlet and outlet openings, the preparation of the liquid by subjecting it to mechanical stirring under vacuum, and thereafter injecting the prepared liquid into the casing through the inlet opening until the casing is filled and filling material flows freely from the outlet. The insulating material may comprise processed cashew nut shell oil to which has been added formaldehyde or powdered paraformaldehyde which causes it to set to an elastic, heat-resisting, electrically-insulating solid. As shown, the liquid insulating material freed from air and gases by mechanical stirring under vacuum, is admitted from a container 41 through a valve-controlled orifice 43, channels 38 and 39 in a plate 22, into the evacuated interior of an ignition coil comprising a core 6 and windings 7, 8 enclosed in a moulded plastic casing comprising a cylindrical portion 9 and end-plates 10 and 11. The coil casing, which may be previously dried in a vacuum oven and is air-tight except for inlet and outlet openings 12, 13 in end plates 10, 11, is yieldingly pressed against the plate 22 by an adjustable support 23, 32, 33 mounted on a cradle 19 suspended from plate 16, so that the inlet opening 12 is in line with channel 39, and the outlet opening 13 communicates with an evacuable chamber comprising a cylindrical glass jar 50 the rim of which makes an air-tight joint with a gasket 17 on plate 16. The chamber 50 is evacuated, and valve 45 is opened to permit the insulating liquid to flow into the casing. When the casing is filled and liquid flows freely from the outlet, air is admitted gradually to break the vacuum in chamber 50, which is then removed. The' filled coil is released from its support, outlet 13 sealed with adhesive tape, a small quantity of insulating liquid is placed in a small cylinder placed over inlet opening 12, to allow for contraction, and the liquid material allowed to solidify on standing, or, more quickly, by baking in an oven. Specification 548,057, [Group XXVII], is referred to.

Abstract: 1379566 Vacuum sewage systems WART1 SILA AB OY and CEMENTA AB 14 Dec 1971 [15 Dec 1970] 57957/71 Heading E1C [Also in Division Fl]  A vacuum sewage system receives sewage from a source, via pipe 5, the sewage passing alternately to each of two tanks 1, 2 (although there may in fact be more than two tanks operating in a similar manner) and being discharged from one of the tanks while the other tank is filling by the operation of means including a vacuum source 16 which is preferably a vacuum pump the outlet of which also provides an air source, valves 9-12 in the inlets and respective outlets of the tanks, and a changeover valve 15 by which it is arranged that whenever vacuum is applied to one tank air is supplied to the other tank. Associated means is provided whereby when vacuum is applied to a tank its inlet valve is open and its outlet valve is shut, and vice-versa when air is applied to the tank. This means preferably comprises control means 20 responsive to leveldetector switches 18, 19 for controlling the valve 15, and pneumatic connections 21, 22 by which the pressure in the tanks controls the inlet valves 9, 10. The control means 20 also controls the outlet valves 11, 12 such that each is opened when the corresponding inlet valve is closed. Instead of exhaust air from the vacuum pump, another source of compressedair or atmospheric air may be used. A sewer 8 receives the sewage from the tanks 1, 2. The system may include a pumping arrangement for pumping drain water from a collecting reservoir 23, the arrangement consisting of a reversing valve 30 which is periodically changed over by a level-detecting switch and timing mechanism so as to supply alternatively vacuum and compressed air from the vacuum pump 16 to a tank 25, the arrangement including valves such as outlet valve 28 which are operated in conjunction with the valve 30 to give the desired pumping action whereby the drain water is first elevated to the tank 25 until the latter is full, and is then discharged to a sewer 24.

A peripheral wall 27 of a wheel 6 which is rotatably trained by a shaft 4, rotates between two stationary walls 12, 16 supported on a bearing 38 to define a first or feed chamber and kernels enter from hopper 3 through opening 15 and are carried in depressions 35 to the bottom of the chamber. At this point bores 28 through the wall 27 can communicate, via semicircular slot 29' in the adjacent housing surface 40, with a source of partial vacuumthe peripheral channel 29 and the kernels are drawn against the bores and are carried to the top of the chamber, where the vacuum is disconnected. Each kernel drops against chute 20 extending from opening 19 and falls through to a second or distributing chamber. This is defined by the wall 16, the stationary housing wall 33, and an end wall 26 which is also rotatably entrained by shaft 4. Further walls 37 extending from wall 26 define pockets 26' aligned with respective bores to receive the kernels which fall through from the first chamber. They are retained in the pockets as the wall revolves until a half revolution has been completed and they reach and can fall through the gap 34 in the retaining wall to the ground. Scraper devices 23, 24, 25 engage the wall 27 to ensure that only the kernels in bores 28 are carried around. In modifications (Figs. 7, 8, 9 not shown) the bores may open out towards the vacuum source to prevent particles becoming lodged in them.
