Title: Spark plugs
IPC: H01T13/46
Filed: 1919-08-06
Abstract: 137,254. Cressy, A. H. Aug. 6, 1919. Sparking-plugs; flame igniters. -The combustion space around the terminals at the inner end of the plug is closed during the latter part of the compression stroke and during the working and exhaust strokes by a sliding valvepiece 11 which seats itself on the inner and outer ends alternately of a valve-seating 6 screwed within the plug casing. The earthed electrode is mounted on the inner face of the end portion of the valve member 11. Charge is isolated in the plug chamber at less than the full compression pressure, and is ignited therein; the increased pressure opens the valve and the issuing flame ignites the main charge in the cylinder. The valve is thereupon immediately reclosed and the plug chamber cut off from the products of combustion. In a modification, a ball moves to and fro between inner and outer seatings.

Title: Dehydrogenation process
IPC: C07C5/333
Filed: 1945-07-30
Abstract: In the production of a diolefine or styrene or a homologue thereof (see Group IV) by the catalytic dehydrogenation of the corresponding olefine or alkyl aromatic hydrocarbon, the reactant is contacted in the presence of at least two molecular proportions of steam at a temperature above 580 DEG C. and at a gaseous hourly space velocity between 300 and 3,000 with a dehydrogenation catalyst consisting essentially of a major molecular amount of iron oxide and/or cobalt oxide in intimate association with a minor molecular amount of chromium oxide and at least 0.2 per cent., preferably 0.5-5 per cent. of alkali.  The iron oxide may be of the pigment type, Luxmass from the production of alumina, or may be prepared by decomposition of ferric nitrate, oxalate, sulphate, or ferric ammonium oxalate.  The alkali may be included as an oxide or hydroxide of an alkali or alkaline earth metal, or as a salt thereof which decomposes to the oxide or hydroxide during the preparation or use of the catalyst. Methods of making the catalyst include mixing the powdered oxides of iron and chromium, decomposing a mixture of the metal nitrates, coprecipitating the hydrous oxides, mixing the hydrous gels or sols, and calcining iron oxide with a decomposable chromium compound.  The mixed oxides may be made into a paste with a solution containing potassium carbonate and tannic acid, extruded and formed into pellets.  A preferred size of pellets has an average volume of about 0.038 ccs.  Materials inert with respect to the iron oxide may be included as carriers or diluents, and in an example 1 mol per cent. of copper sulphate is present.  Before use the catalyst may be heated at 700-1,000 DEG C., preferably 800-950 DEG C.; its activity may be restored by steaming or by the addition of alkali, for example, by including potassium carbonate with the steam.ALSO:In the production of a diolefine or styrene or a homologue thereof by the catalytic dehydrogenation of the corresponding olefine or alkyl aromatic hydrocarbon, the reactant is contacted in the presence of at least two (preferably 7-30) molecular proportions of steam at a temperature above 580 DEG  C. and at a gaseous hourly space velocity between 300 and 3000 with a dehydrogenation catalyst consisting essentially of a major molecular amount of iron oxide and/or cobalt oxide in intimate association with a minor molecular amount of chromium oxide and at least 0.2 per cent of alkali (see Group III).  Butadiene is prepared from butylene; styrene, methyl styrene and dimethyl styrene from ethyl benzene and its homologues; isoprene from methyl ethyl ethylene, trimethyl ethylene, or isopropyl ethylene, or mixtures thereof.  Reference is also made to the production of piperylene and hexadienes.  The reactants may be diluted with paraffin hydrocarbons, which are not reduced.  A temperature of 590-690 DEG  C. and substantially atmospheric pressure is preferable for the production of butadiene.  The process may be carried out in a fluidised catalyst or moving bed system.

Title: Process for the production of aluminium chloride and alumina
IPC: C01F7/22
Filed: 1922-07-18
Abstract: An aluminium chloride solution which may be obtained by treating calcined clay with hydrochloric acid (or with aluminium chloride solution enriched with hydrochloric acid) is evaporated to produce a crystal sludge from which mother-liquor is separated. The crystals are washed with hydrochloric acid or first with some of the original solution and then with pure hydrochloric acid (for instance of 20 per cent strength), the mother-liquor and washings being used to absorb hydrochloric acid arising from the calcination of the crystals to obtain alumina (when such calcination is effected), or from other sources and used, according to their content of iron either for washing the crystals or for treating more clay.  When the solutions accumulate too much iron they are evaporated and calcined to produce hydrochloric acid.

Title: Registering device for card games
IPC: A63F1/18
Filed: 1928-07-06
Abstract: 294,475. Sanders, N. July 23, 1927, [Convention date]. Indicators, declaration, trump, and like.-An apparatus for indicating calls in card games such as bridge, comprises a single controlling element for mechanically indicating, at the same time, the trump called, the number of tricks in these trumps, the total number of tricks to be made and the scoring value of these tricks. A key 15 is provided for each suit and for " no trumps." The mechanisms of the keys are similar and each comprises a train of wheels 4, 14, 13, 12 operated' step-by-step by a pawl 16 upon successive depressions of the key. A drum 3 is thus caused to indicate, at windows 1, 2, corresponding to the key the number of tricks called and the total tricks required. At the same time a drum 11 indicates, at windows 9, 10, the points representing the scoring value of the tricks, and a masking sector 7 is moved by a cam 18 so as to display the suit symbol through an orifice 6. A sector 30, retained bv a notched pawl 33, is set by a knob 32 to indicate whether the game is played under normal, doubled, or redoubled conditions. Knobs 35, 36 are used for setting drums behind windows 37, 38, to display the number of games won. A lever 24 is provided adjacent each key 15 for zeroizing the drums 3, 11, and masking the disc 5, the depression of the lever liberating a pawl 25 from a ratchet wheel 26 and allowing the drum mechanism to return under the action of a spring 22. To zeroize the drums simultaneously and at the same time to return the sector 30 under the influence of a spring, a knob 27 is rotated, thereby raising arms 29 so as simultaneously to displace all the levers 24 and pawls 25, and at the same time to displace the notched retaining pawl 33. The indicating numerals may be carried on endless bands.

Filed: 1976-05-14
Abstract: 1535974 Containers for seedlings H A SPENCER 14 May 1976 19957/76 Heading A1E Seedlings are grown in individual cells, each cell having downwardly directed grooves formed in its side walls for directing roots downwardly to an aperture in its base, air circulating beneath the base causing roots penetrating the aperture to wither (air pruning) and thereby encourage branching of the roots. In one embodiment a container is formed by members 51, 52 hinged together at 62 and each having shoulders 53, 54 co-operating with the shoulders of the other member to form a series of cells. Grooves 68, 69 direct roots vertically downwardly to the bottom of the cell. In the opened condition of the container slits 67 are provided between each hinge 62; when the container is erected the slits open to form large drainage and air pruning apertures. Each alternate shoulder has a rebate 55 formed along most of its length, with a short rebate 57 formed on the opposite side near the top, intervening shoulders, and corresponding shoulders of the opposite member, being oppositely rebated at 56, 58 so that the non-rebated portion of one shoulder engages the rebated portion of the opposite shoulder to form an interlocking shiplap joint preventing intermingling of the plant roots.  To facilitate filling the cells with growing medium and to hold the containers erected, they are placed back-to-back in a box having a grid base, and during growth of the plants the boxes are raised above the ground to ensure air pruning. In modifications the members 51, 52 are formed with frictionally engaging stud-andsocket connections to maintain the container erected. The cells may be straight sided and be provided with a growing medium-retaining bar extending across the bottom which is otherwise open. The members 51, 52 may be formed separately instead of being hinged together.
