Title: Improvements in or relating to pressure pads for presses
IPC: B30B15/06
Filed: 1951-05-03
Abstract: 708,070. Pressing-plates. MATHER, R. April 28, 1952 [May 3, 1951], No. 10442/51. Class 69 (2). [Also in Group V] A resilient pressure pad for a moulding or like press comprises a body having a substantially cylindrical spigot, a cap telescopically slidable over the spigot, and a resilient frusto-conical washer interposed to advance the cap relatively to the spigot. The body 20 is screwed to the under surface of the upper platen of the press and its spigot 24 has at its end a cylindrical surface 29 over which the cap 25 slides. The cap 25 is retained against the pressure of the resilient washer 36 by a circlip 30 which springs outwards into a semi-circular groove 31 in the cap. To enable the circlip to be contracted sufficiently for the device to be dismantled a groove 32 is formed in the spigot 24. Notches 35 are cut in the edge of the flange of the cap to allow the circlip to be pushed inwards. More than one spring washer may be used. Alternatively the body 20 may be secured to the upper surface of the base of the press.

Title: Improvements in or relating to the production of magnesium hydroxide
IPC: C01F5/22
Filed: 1940-06-17
Abstract: 542,007. Mixing &c. OCEAN SALTS (PRODUCTS), Ltd., and PICKETT, F. N. June 17, 1940, No. 10490. [Class 86] [Also in Group III] Magnesium hydroxide is produced from liquors containing convertible magnesium salts by precipitation with a basic-reacting liquor ; two flat streams of the liquors, of practically the same width which is considerably greater than the depth, are arranged so that one is above the other and drops to it for mixing. The rates of flow of each can be adjusted according to the respective concentrations of magnesium salts and base so that the mixed liquors are substantially free from magnesium ions. The settling tank 24 is arranged in conjunction with a trough 14 of wood slightly inclined to the horizontal, which has at its top end-two launders 16, 17 for sea water, and a smaller launder 18 for milk of lime. The launders are provided with adjustable weirs 22, 23 over which the liquids flow. The milk of lime liquor is supplied to the launder 18 and flows over the weir 23 to drop on to a mixing table 15 of stainless steel. The sea water is supplied to the launder 16 and passes through a filter 19 to the launder 17 from which it passes over the weir 22 and falls a short distance to mix with the stream from the launder 18 upon the table 15. The mixed liquors flow in a shallow stream to the end of the trough 14 above the centre of the conical tank 24 which is filled to the brim with water. The magnesium hydroxide falls through the opening 14b in the trough and settles at the bottom of the tank from which it is withdrawn as desired. The liquid overflows into the launder 25. The milk of lime is diluted in accordance with the rate of flow of seawater so that just sufficient lime is added for the purpose. In a modification the supply launders are circular and are arranged completely round the settling tank with the lime launder inside the sea water launder. In this case each launder has a skirt over which the liquor is discharged, and deflectors with vanes are provided to ensure an even distribution of liquid round the circle. The rate of flow of each liquid is varied by means of adjustable and detachable baffle plates.

Filed: 1925-04-22
Abstract: 239,455. Haddan, P., (Kienzle Uhrenfabriken Akt.-Ges.). April 22, 1925. Striking-mechanism; chimes.-Quarter-chiming mechanism comprises a detent lever 11 having a detent 16 adapted to release the stud 17 on the detent wheel of the chiming train. This detent lever 11 has pivoted to it at 12 a two-armed lever 10, 13, the arm 10 being actuated by a pin 9 on a warning lever 7, a pin 8 on a part 6 and a four-toothed star wheel 1, connected to the minute spindle, of which the <4>/4 tooth 5 is longer than the teeth 2, 3, and 4 for other quarters. The other arm 13 coacts with notches 18, 19, 20, and 21 in a gathering pallet 14 and has a lug 15 engaging under the lever 11, the <4>/4 notch 18 being deeper than the other notches. Fig. 1 shows the mechanism about to chime the third quarter. As the wheel 1 rotates clockwise the tooth 4 lifts the pawl 6, the stud 8 lifts the warning lever and the stud 9 rotates the lever 10, 13 until the end rests at the bottom of the ¥ notch 21 which now acts as a fulcrum for the lever 10, 13 so that on further upward movement of the pawl 6, the lug 15 lifts the detent lever 11 and the stud 17 is released chiming then proceeds, the arm 10 being held up by the stud 9 and the end of the arm 13 riding along the ¥ ridge between notches 21 and 18 until it drops into the notch 18, relocking the chiming train. The wheel 14 is driven from this train. Fig. 2 shows an abnormal position in which the arm 13 engages in the <4>/4 notch 18 while the minute spindle is only at the third quarter and therefore the ¥ tooth 4 is at the pawl 6. The tooth 4 does not, however, raise the pawl 6 sufficiently to allow the deep notch 18 to act as a fulcrum to the arm 13. The chiming train is not released and the gathering pallet remains stationary until the longer 4/4 tooth 5 comes to the pawl 6 at the hour. The mechanism is also applicable to striking mechanism.

Title: Catalytic reforming of hydrocarbons and apparatus therefor
IPC: C10G11/12
Filed: 1956-04-11
Abstract: 803,788. Gas manufacture. GAS MACHINERY CO. April 11, 1956 [Jan. 23, 1956], No. 11009/56. Class 55 (2). Liquid or gaseous hydrocarbons are catalytically reformed in a pair of shells 31, 32 used alternately by reversal of flow and having a crossover 33 joining their tops, by first heating the catalyst bed 40 in one of the shells, say 31, by passing air upwardly through the bed 40 in the other shell 32 from the intake 53, the heated air being mixed with atomized liquid fuel and primary air from one or both of the burners 52 in its path between the beds 40, the combustion products passing through the passage 35 to the stack 44 ; then by passing a stream of a gaseous vehicle, steam being particularly mentioned, from the inlet 55 along the path of the air and introducing the hydrocarbon, from one or both nozzles 57, into the steam so that the mixture passes downwardly through the previously heated catalyst bed 40 ; and passing the products of the reaction through the conduits 43, 47 to a wash-box and storage reservoir. A heat run in the shell 32 then follows. The steam may, after the heating of the catalyst bed, be admitted, for a short time, without admixture with hydrocarbon, to purge air from both catalyst beds, the exhaust from the purging operation being passed to the stack 44 or to a waste-heat boiler connection 46. Also the flow of steam, without admixed hydrocarbon, is continued for a short time at the end of the make run, to react with carbon in the catalyst bed and restore the activity thereof. The carbon may be more completely removed by a brief passage downwardly, through the catalyst, of regenerative air from the other shell, the resulting C0 2  and N being exhausted to the stack or to the waste heat boiler. As shown, the beds 40 are supported on grills 39 carried by conventional regenerator checkerwork 38. In a modification, an upper checkerwork structure is arranged above each catalyst mass which is built up of closely packed columns of stacked star-sectioned elements 65, Fig. 6, of porous refractory ceramic materials impregnated, in known manner, with nickelous oxide. Reformed gas may be bled off from below the catalyst bed and reintroduced with the process steam to provide a more reducing atmosphere. Also the catalyst in the shell just subjected to a heat run may be reactivated by contact with reformed gas which is admitted at the bottom of the other shell. It is preferred to introduce all, or nearly all, of the fuel downwardly in countercurrent to the regenerative air rising in the shell which is not being subjected to the heat run. In this case the combustion is substantially completed before reaching the catalyst bed in the shell being heated, the bed being thus protected from impingement by hightemperature flames. The make oil, or most of it, is likewise directed downwardly in the regenerative shell, so that the steam and oil are thoroughly mixed in the cross-over, 33 before reaching the catalyst bed.
