Title: Improvements in and relating to rotary tilting furnaces
IPC: F27B3/00
Filed: 1950-12-29
Abstract: 694,129. Rotary tilting furnaces. BLANCHARD, P. Dec. 29, 1950 [Dec. 29, 1949], No. 31604/50. Class 51(ii) In a combined rotary and tilting furnace for the melting of metals, the furnace 1 is disposed on driven rollers 3 on a segmental cradle member 2 formed with a platform 10 on which is disposed a carriage 11 carrying a burner 7, and a telescopic air ducting 8 connects said burner and a fixed air pipe 9 co-axial with the axis of the cradle 2 to allow for the longitudinal tilting movements of the furnace on rollers 6. Intermittent teeming of the molten metal may be arranged for by providing a discharge spout 20, Fig. 3 partially encircling the furnace wall 21, whereby on rotation of the furnace in a clockwise direction at each revolution a volume of metal is discharged equivalent to the capacity of the spout. Rotation in an anti-clockwise direction results in the alternate filling and draining of the spout from the furnace without discharge externally thereof. Slag may be teemed off through the end of the furnace without stopping rotation and by rocking the furnace additional mixing of the contents is ensured. In a modified furnace Fig. 2 (not shown) the burner is not mounted on a carriage but is suspended on a chain passing over fixed pulleys and carrying a counterweight.

Title: Methods for air contitioning aircraft cabins and devices for carrying out the methods
IPC: B64D13/06
Filed: 1974-07-18
Abstract: 1469555 Air conditioning an aircraft cabin VEREINIGTE FLUGTECHNISCHE WERKE FOKKER GmbH 18 July 1974 [18 July 1973] 31915/74 Heading F4V An aircraft cabin 5 is air conditioned by feeding compressed air (either from a compressor of the aircraft engine 1 through a line 2 and'preliminary cooler 3, or from an auxiliary gas turbine 10) to a first cooling turbine 11 (where the air expands and cools), mixing the expanded air at point 13 with return air from the cabin to form mixed feed air, feeding the mixed air through a heat exchanger 14 to a second cooling turbine 15 (where the mixed air expands and cools), feeding the expanded mixed air to a water separator 8 and thence to the cabin 5. The heat exchanger 14 is air-cooled, the cooling air being caused to flow by a fan 12 driven by the turbine 11. A part of the cabin air is recirculated by returning it to the mixing point 13 via a filter 9, and a compressor 16 driven by the second cooling turbine 15. The remainder of the cabin air is exhausted through a pressure control valve 6. In the case of low engine pressures, the first cooling turbine 11 can be shunted by line 19. To control the temperature of the air entering the cabin from the water separator 8, air of higher temperature can be added through a shunt line 4. Modifications are illustrated in the following Figs. (not shown). Fig. 2:- the two cooling turbines (21, 25), and associated compressor (26) and fan (22) are all mounted on a single shaft. Further, the feed air to the cabin and the return air therefrom are cooled in circuits (24a) and (24b) through a single heat exchanger (24). Fig. 3:- the fan (32) for drawing cooling air through the heat exchanger (34) is provided with a shunt (30) whereby, when the plane is in flight and ram air is used for cooling the heat exchanger (34), the fan (32) can be bypassed. Fig. 4:- air can be arranged to by-pass the heat exchanger (44), by a shunt (47) including a temperature control valve (47a). Further, there is an additional air inlet nozzle (not shown) for the second turbine (45) fed by a branch line (48) for use when there is a pressure drop at the engine compressor.

IPC: F16H63/20
Filed: 1960-09-16
Abstract: 935,501. Change-speed control. VAUXHALL MOTORS Ltd. Sept. 15, 1961 [Sept. 16, 1960], No. 31937/60. Class 80 (2). Manual gear-shift mechanism comprises a selector shaft 2 actuated by the usual gear shift lever 6 and rotated to bring a recess 14 in a selector spade 13 into engagement with a lug 18 of a striker 15 or 16. The strikers 15, 16 are slidable on a common rail 17, the selector shaft 2 being slid axially to move the selected striker to establish the gear. Reverse is controlled by a third striker (not shown) mounted on a separate rail and engaged by the spade 13. The non-selected strikers are locked in their neutral positions by a circumferential groove 22 in a collar 20 which rotates with the shaft 2 but is fixed axially by a locating pin 19 engaging in a slot 30 in the collar 20. An axial slot 21 in the collar accommodates the spade 13. One angular position of the collar 20 and spade 13 for selecting one striker is determined by the side of the pin 19 engaging the base of the slot 30, another position is determined by the base of the slot abutting a spring-pressed stop-pin 24. Further rotation of the shaft 2 and collar 20 against the pressure of the pin 24 until the base of the slot engages the end of pin 19 selects the reverse striker. The axial positions of the selector shaft 2 are determined by a ball detent 11 engaging peripheral grooves 12 in the shaft.

Title: An improved centering device for use in machining crankshafts, eccentrics or the like
IPC: B23B5/22
Filed: 1927-11-28
Abstract: 288,932. Benz, J. Nov. 28, 1927. Chucks. - A device for setting up crankshafts &c. in a lathe, grinding or other machine comprises a plate 1 adapted to be secured to the face-plate of the lathe and carrying a bolt 15 on which a carrier 2 is pivoted. The carrier is guided and locked by a bolt 13 sliding in a slot 6 concentric with the bolt 15 and supports a concentric face-plate 3 rotatable about its centre under the guidance of a bolt 14 and an arcuate slot 19 in the carrier. An arcuate slot 7 in the carrier, concentric with the bolt 15, receives a bolt or roller 9 which is fixed to the plate 1 and also passes through a radial slot 8 in the face-plate 3. In operation, the bolt 9 is set co-axial with the lathe centres and a chuck 5 rotatable with the face-plate 3 is made to grip an end journal a of the crank-shaft, the centre-line 22 of the crank-webs being made to coincide with the axis of the radial slot 8 and being adjusted parallel to a setting surface 12 when the bolt 13 is opposite the graduation O on the scale 17, as in Fig. 1. The journal a is then operated upon while the lathe face-plate rotates, after which the bolts 9, 13, 14 and 15 are released and the carrier 2 is rotated about the bolt 15 until the bolt 13 arrives at the graduation on the scale 17 representing the required length of crank, the position shown in Fig. 2 indicating a length of 40 millimetres. During this rotation of the carrier the bolt 9 slides along both slots 7, 8 and causes the centre line 22 of the crank-webs always to pass through the axis of rotation of the lathe, i.e. the centre of the bolt 9. The crank-pin b is thus co-axial with the lathe centres and may be operated upon after the bolts have been locked. To machine the opposed crank-pin c, clamps 10 are released and the central part 4 of the face-plate 3 is rotated through 180, thus bringing the crankpin c into line with the lathe centres. In a modification the slots 7, 8 in the carrier and faceplate respectively are dispensed with and replaced by a curved slot in the plate 1 receiving a bolt passing through the point 24 of the face-plate, the shape of the slot being that traced by the point 24 during the above described motions. Alternatively, the curved slot and the slots 7, 8 may all be used together.

Title: Improvements in or relating to processes for the surface treatment of materials
IPC: B05D3/12
Filed: 1952-12-17
Abstract: <PICT:0745057/III/1> A fusible or thermoplastic material is applied in powdered form in a substantially thin layer upon a surface of a nonmetallic transfer plate, foil or band having poor thermal conductivity or upon the surface of a rigid article or an article which becomes rigid after treatment especially a wooden board or a composite board containing wood wool or shavings, the fusible or thermoplastic material is heated until it is in a plastic condition whereupon the surface of the transfer plate, foil or band and the surface of the article are pressed together to produce a polished surface on the article.  Glass, ceramic or other plates having a glazed surface may be used, or the foil or band may be of plastic. They may be pressed on to the article by yieldable heat-insulating supports which may, if desired, be equipped with heating wires or sources of radiant heat. Separating layers of waxes or silicones may be applied to the transfer plate prior to the application of the fusible material. Yieldable materials such as felt, asbestos or rubber may be used on the reverse side of the article to be treated, these serving also as extra heat insulators.  If desired, the process may be carried out continuously by means of an endless transfer band, the articles to be treated travelling parallel to and at the same speed as the band.  Specified fusible substances include polyacrylic and polymethacrylic compounds, polyamides, polyvinyl acetate, polyvinyl chloride, fusible phenolic and urea resins, natural resins, cellulose derivatives and other organic and inorganic substances fusible without pressure, with or without the addition of plasticisers, fillers (glass powder, fine asbestos fibres, pure silica) or colouring agents.  Mixtures of these substances which melt at low temperatures giving a melt which after hardening or gelatinization has a higher softening temperature may be used.  As shown (Fig. 1) an insulating mass in a container 3 is uniformly applied by a spreader 4 to an endless travelling band 2.  A fusible or thermoplastic material from a container 5 is then applied and heated by a device 7.  The articles to be polished 8 are carried along by a travelling band 10 at the same speed and parallel to the band 2 which is pressed by rollers 9 into contact with the articles 8.  Additional pressing rollers 12 may be provided to assist in holding the article and band 2 in contact.  The band 2 and article 8 then pass over cooling rollers 13 and the article is removed from band 10. Articles with uneven surfaces may be treated by using yieldable rubber bags filled with a pressure medium to obtain the pressing action.  If desired, the articles to be treated may be situated below the band 2.  In a modification a polished surface may be restored or repaired by using a foil coated with a separating agent and remelting the polished surface by means of a hot laundry iron or similar heating means.

Title: Stabilization of liquid sulfur trioxide and oleum with liquid silicon compounds
IPC: C01B17/90
Filed: 1953-11-20
Abstract: Liquid sulphur trioxide or oleum of SO3 strength (eg., 80 per cent or more) such that SO3 polymers tend to form are stabilized by adding a liquid monomeric saturated silicon compound of formula X-M-Y, where X is at least one of the radical Cl, F, methyl, or methoxy, M is silicon or disiloxane, and Y is at least one of the radicals Cla, Fa, (CH3)b or (OCH3)b, a being an integer from O-3, which is O when M is silicon, and b being an integer from O-3, which is O, 1 or 2 when M is disiloxane, and wherein, when M is the disiloxane nucleus, the compound contains at least one of the radicals Cl or F, all otherwise unsatisfied silicon valencies in the molecule being filled with hydrogen.  Suitable compounds are tetramethyl-, tetramethoxy-, trimethyl-, trimethyl methoxy-, and methyl trichlorosilane, or hexachlorodisiloxane, and 0.05-1.0 per cent may be used, although in most cases 0.05-0.2 per cent is sufficient.  The liquid SO3 may be prepared by distilling 30 per cent oleum and condensing the gas at 20-30 DEG C., or by compressing the gas from a catalytic SO2-oxidation to 160-170 lbs./sq. in. and condensing SO3 by cooling to 20-25 DEG C.  The silicon compound should be added to anhydrous SO3 or to oleum containing at least 99.4 per cent free SO3 and may be mixed by agitation.  Alternatively SO3 may be condensed in a vessel containing the silicon compound. The addition may be effected at atmospheric pressure or higher, if the silicon compound is not ordinarily liquid.

Title: Improvements in or relating to internal combustion engines provided with electrical ignition
IPC: F02P3/10
Filed: 1947-12-08
Abstract: 650,884. Fuel injection engine with spark ignition. SMITSVONK, N. V., and SNEL, R. Dec. 8, 1947, No. 32367. Convention date, Nov. 28, 1946. [Class 7(iv)] In an engine which operates with fuel injection and a compression ratio higher than 1:10 but less than the value at which ignition is caused exclusively by the compression heat and in which the moment of ignition is determined'by'an. electric spark only; the ignition is caused by means of a surface discharge sparking plug adapted to be used at voltages under 3;000 volts and by means of a condenser which is periodically directly discharged through the sparking plug. It is stated that'the ignition by discharge of a condenser through a surface discharge sparking plug is not approciably influenced by the pressure in the combustion space. It is therefore possible to increase the compression ratio to a value e.g., 1:15 at which self-ignition by compression heat just does not occur. The fuel is advantageously injected towards the sparking plug. The invention is applicable to two-stroke and four-stroke cycle engines. Specification 483,383 is referred to. According to the Specification as open to inspection under Sect. 91 the invention is applicable to mixture suction engines. The fuel may be led into the combustion space in the neighbourhood of the sparking plug. This subject-matter does not appear in the Specification as accepted.
