Abstract: 995,101. Rotary piston I.C. engines. KLOCKNER-HUMBOLDT-DEUTZ A.G. Aug. 16, 1962, No. 31469/62. Heading F1F. A rotary-piston internal combustion of the Wankel type has an auxiliary combustion chamber 12 communicating by means of one or more ducts 11 with the main combustion chamber 8, 9. The duct or ducts are arranged to produce a swirling action in the auxiliary combustion chamber, and fuel is injected by an injector 14 either radially into the auxiliary combustion chamber (Fig. 1), or is deposited as a film on the wall of the chamber (Fig. 2). An ignition plug 15 or 16 is fitted, either to assist in starting, or for continuous use. In another embodiment (Fig. 3), fuel is injected into the working chamber 9 and the mixture expands into an auxiliary chamber 19. Fuel may also be injected into the port 8 of the working chamber. The invention is also applicable to engines in which the rotor has one lobe less than the housing (Fig. 4, not shown), the auxiliary chamber being located in the rotor.

A lever lock 10 is provided with a plurality of levers 13 mounted on a common lever pivot 17 for actuation by a double bitted key 19 which has different lever steps each for engaging in a cutout 18 in an associated lever, each cutout having a generally rectangular shape adapted to the size of the double lever bit to be inserted therein and provided with substantially arcuate oppositely located curved depressions 18a, 18b on its longitudinal sides, the oppositely directed lever steps of the key each acting substantially simultaneously on one of the arcuate depressions of a lever when the. key is turned, each pair of oppositely located lever steps complementing one another to the same length, in which the curved depressions of all or substantially all the levers are congruent and correspond to outer curves created by arcs of all the different circles described by individual lever steps each about its respective centre relatively to its lever, the centres of adjacent circles being spaced corresponding to the interval between the depth of one lever step and that of the next longer or shorter lever step and lying on an arc centred on the lever pivot, each such interval subtending substantially the same angle at the centre of the arc. As shown, the lever group 13 and a flank lever 15, are each provided with a pocket 23 for engagement with a bolt stump 20 in the path of the bolt 12 when all the pockets are aligned by the key to unlock the lock. The bolt is guided on a stump 27 by a lanket hole 26 and the key steps are arranged to engage the upper and lower depressions in the levers at an angle of about 65 degrees to a line L connecting the lever pivot and the centre line of the key bit. The flank lever 15 is provided with a pin 28 which restores the levers to the locking position under the influence of a spring 29 and a projection 30 on the flank lever 15 prevents withdrawal of the key in a position other than the locked position of the levers. When the key is turned to the 65 degree position a recessed bolt step 19b thereon engages in a recess 31 in the bolt talon to withdraw the bolt. In a modification, Figs. 7 and 8 (not shown) the levers are each provided with a pocket (34), the talon of the bolt is provided with recesses (35), (31), and the key is provided with an additional bolt step (19c) to permit rotation of the key through a further 180 degrees to move the bolt to a further unlocked position or beyond its unlocked position in which it actuates a door latch through a runner (36) or in which a door latch is actuated by the key. In this embodiment, a suitably modified flank lever (38) is used.

Abstract: 871,109. Steam superheaters. FOSTER WHEELER Ltd. July 11, 1957 [Oct. 23, 1956], No. 32273/56. Class 123(3) Saturated or partly superheated steam from a water tube boiler 12 is heated to its final temperature in a separately-fired superheater 10 which may be disposed near the turbines &c., supplied from the boiler. The superheater is fired by oil burners 22 and receives combustion air from a forced draughed fan 24 also supplying air to the burners 32 of the boiler. Air from the fan 24 is proportioned between the boiler and superheater by dampers 26, 28, the opening of the damper 26 being regulated in accordance with the flow of steam through the superheater and its temperature to maintain the latter constant. The superheater 10 is supplied with excess air, the final steam temperature being regulated by variation of the proportion of this excess air by adjustment of the damper 26. Hot, oxygencontaining gases leaving the superheater are led through a mixer device 30 into the duct conveying air to the boiler burners 32. In a modification, the boiler has an integral superheater from which the steam flows directly to the independently-fired superheater and provision is made for some of the partly superheated steam to be branched off for use when required in auxiliary machinery, the temperature of the withdrawn steam being adjusted in an air desuperheater disposed in the duct conveying combustion air to the boiler burners.

Abstract: 1431072 Non-foamed pressed glass UNIVERSITY OF CALIFORNIA REGENTS OF 6 July 1973 [5 July 1972 (2)] 32332/73 Heading C1M A method of making a non-foamed glass product comprises mixing particulate usedcontainer glass together with a glass filling agent which is defined as an inert substance that will not foam under the conditions of the method, said used-container glass having the following concentration of foreign inclusions contained therein in per cent by weight, 0À1- 3 Fe, 0À1-2 Sn, 0À1-2 Al, 0À1-1 other metals, 0À1-1 cellulosics, 0À1-1 other organics and having an average reflectance of 5-95%; subjecting the resulting mix to temperature and pressure conditions sufficient to sinter and soften said glass but insufficient to melt said glass; maintaining said mix under said conditions while pressing said mix until said glass has been converted into a pressed glass coherent mass having a decorative multi-coloured appearance; and thereupon cooling said mix to below the solidification point thereof and recovering the glass product. The glass filling agent may be fly ash, sand, clay, asbestos, fibreglass together with additives such as pigments may also be added, but is preferably heat treated excreta which may be derived from sewage plant cake, livestock excreta and poultry excreta. Heat treatment is suitably carried out at 200- 1000 C. Typical heat treated excreta derived from human sewage cake contains 17À5 wt. per cent carbon, 1À7 wt. per cent hydrogen, 14À7 wt. per cent Si, 1À0 wt. per cent Al whilst heat treated excreta derived from cow dung may contain 31 wt. per cent carbon, 10 wt. per cent silicon, 3 wt. per cent alumina and 2 wt. per cent hydrogen. The treating temperature of the mix of glass and glass filling agent is usually kept at 500-1000 C. while treating pressures of 10-10,000 p.s.i.g. are applied. Typical evidence times for pressing operations are 1 second-60 minutes. The hot pressing can be supplemented by applying to surface(s) of the pressed product pigments in the form of inorganic oxides such as ferric oxide or lead oxide, or metals and/or sheets of glass to which the pressed product is bonded under suitable heat and pressure. Products may be used for roofing, floor and wall tiles, artificial slate or marble.
