Patent GB-710118-A (GB)
Title: A process for the production of iron catalysts for the hydrogenation of carbon monoxide
Inventor: KOELBEL HERBERT
IPC: B01J23/78
Filed: 1951-08-27
Abstract: Catalytic hydrogenation of carbon monoxide is carried out with a catalyst comprising iron together with kieselguhr, copper, an alkali metal and an alkaline earth metal as activators or carriers (see Group III) at temperatures of 185 DEG -235 DEG  C. at normal pressures or with 10-50 atmospheres gauge pressure at 190-220 DEG  C. The catalyst may be reduced before use.ALSO:An iron catalyst containing kieselguhr, copper, an alkali metal and an alkaline earth metal as activators or carriers is prepared by precipitating a solution containing the nitrates of iron, copper, and the alkaline earth metal by adding it in batches of increasing quantity to a solution of an alkali metal carbonate or hydroxide in which kieselguhr is suspended, allowing carbon dioxide evolution to cease after each addition before adding a further quantity of nitrate solution, bringing the catalyst slurry to the boil within 5 to 20 minutes of completion of precipitation, and boiling the slurry for a further 2 to 7 minutes.  The catalyst is then filtered, washed and dried, the desired alkali metal content being obtained by incomplete washing and/or by impregnation.  The drying is preferably carried out below 80 DEG C. and the catalyst may be reduced with a hydrogen-carbon dioxide mixture.  An excess of 5-4 per cent. of alkali metal is preferably used in the precipitation and the nitrate solution concentration is preferably not lower than 2 per cent. 5-40 per cent. nitric acid may be added to the nitrate solution.  In an example 100 parts of iron, 10 of copper and 15 of magnesium as nitrates are dissolved in water to give a 6 per cent. solution to which is added 12 per cent. of HNO3.  This solution is added in batches of 6, 12, 15, 19, 22 and 26 per cent. successively to sodium carbonate solution containing suspended kieselguhr.  The slurry is brought to the boil in 9 minutes and boiled for 3 minutes, after filtering and washing, the precipitate is alkalied with 20 per cent. of potassium carbonate and dried at 50 DEG C., optionally followed by reduction.

Title: Improvements in and relating to water treatment plant
IPC: C02F1/20
Filed: 1938-07-11
Abstract: 506,616. Purifying and softening water. PERMUTIT CO., Ltd. July 11, 1938, No. 20541. Convention date, July 10, 1937. [Class 46] [Also in Group III] In an apparatus for de-aerating water, the water flows through a preheater 17 furnished with a gas vent 19 into an inner chamber 13 surrounded by an annular chamber 10 which communicates at the top with the inner chamber and contains an arcuate steam heating pipe 23 extending largely round the annular chamber. The water then flows from the inner chamber to the annular chamber by the opening 26 and is caused to traverse the annular chamber along the length of the steam heating pipe while being heated by the latter before leaving the annular chamber by pipe 27, while the steam and gases from the annular chamber enter the preheater so that the incoming water is preheated and the gases vented. A float operated valve 21 controls the supply of water which is sprayed, by the nozzle 20 into the chamber 13 thereby washing exhaust steam which may be introduced by the pipe 29. The partition 28 between the opening 26 and pipe 27 ensures that the water traverses a substantial part of the chamber 10. The latter may however be divided into two equal parts by another partition, one part receiving water from the chamber 13 while the other is used to de-aerate other water such as condensed steam. In this case, the steam pipe 23 may be perforated and supplied with exhaust steam, the pipe 29 being dispensed with. The modification shown in Fig. 4 has a settling chamber 31 in communication with chamber 13, in which solid matter may settle and be removed by the valve 36. The settling process may be accelerated by the addition of chemicals such as lime or soda which may enter by pipe 35. The water leaves the settling tank by the conical uptake 33 and enters the annular chamber by pipe 34 in which any hardness caused by the previous addition of chemicals may be removed by alkali phosphate added through the pipe 37. In this modification the annular chamber 10 may surround the top part of chamber 31 and be connected to it by openings at the top. The Specification as open to inspection under Sect. 91 comprises also the following subjectmatter : the steam pipe need not traverse a substantial part of length of the annular chamber. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in the filling of ice cream into containers
Inventor: STONESTREET GEORGE ALEC
IPC: B65B3/32
Filed: 1950-08-23
Abstract: 687,173. Delivering measured quantities of liquid. WALL & SONS, Ltd., T. Aug. 9. 1951 [Aug. 23, 1950]. No. 20828/50. Class 106 (v). [Also in Group XVII]. A continuous method of filling predetermined quantities of ice cream into containers comprises passing a stream of ice cream issuing under pressure from a chilling and emulsifying apparatus into a chamber through a conduit connected to the exit end of said apparatus, displacing the chamber with respect to the conduit when the predetermined quantity of ice cream has entered the chamber and ejecting the ice cream from the displaced chamber into the container to be filled. The ice cream is fed under pressure from chilling and emulsifying apparatus 23 through a conduit 22 to a transverse cylindrical bore 2 in a cylindrical member 1, a rod 10 moving a free piston 3 in said bore to suck the ice cream into the bore, alternatively the rod 10 may be dispensed with and the piston 3 moved by pressure of the ice cream. The member 1 is then rotated by a rod 6 to a discharge position where the piston 3 is moved by a rod 16 to discharge the ice cream into a container A. The amount delivered may be varied by adjusting a nut 13 on the rod 10 or, if the rod is not fitted, by varying the rate of delivery of icecream into the measuring apparatus.

Title: Improvements in or relating to record card controlled sorting machines
Inventor: HOLDEN NORMAN GEOFFREY
Filed: 1949-08-10
Abstract: 675,212. Statistical apparatus. POWERSSAMAS ACCOUNTING MACHINES, Ltd. Aug. 8, 1950 [Aug. 10, 1949], No. 20856/49. Class 106 (i). In a sorting machine of the type having a device for comparing data automatically settable in two columns of differentially settable registering elements such as racks or slides, there is provided manually-operable means associated with one column to set in data manually to the exclusion of any automatic setting, the primary purpose being to dispense with a master card which would be sensed repeatedly until ultimate damage resulted to the perforations. Fig. 1 shows two such slides 11 and 12 differentially set by plungers 5 co-acting with members 3 and 4, sliding blocks 1 and 2 and interconnecting links 6 pivoted at 7 and 9. The left-hand side of the apparatus is further provided with an inclined wedge 17 sliding in suitable guides and operated by a handle 16a. A spring loaded detent 26 cooperating with grooves 24 in the underside of plate 19 positions the wedge accurately for settings 0 to 9. The wedge 17 is so made that when it is displaced to the right by moving the handle 16a to any of the positions 0-9, the slide 11 is displaced by the correct amount by engagement of the pin 30 by the wedge 17. During each machine cycle combs 13 oscillate to remove the amount previously set in to the differential members 11, 12, by the plungers 5. In order to prevent oscillation of the left-hand comb after manually setting a number, so that the manually set displacement of slide 11 remains until removed manually, an extension piece 32 is fixed to the comb 13 and is engaged by a pawl 33 pivoted at 34. When the handle 16a is in the zero position a pin 36 engages the tail 37 of the pawl 33 and keeps it out of the way of the member 32 which is then free to oscillate with the comb 13. On moving the handle 16a to any other setting with vertical displacement of the member 11 the pawl 33 urged by the spring 35 engages the extension piece 32 and prevents oscillation of the comb 13 while the manual setting remains. Specification 597,492 is referred to.
