Patent GB-756652-A (GB)
Title: Improvements in or relating to the preparation of ammonium sulphate
Inventor: PLUIM JAN
IPC: C01C1/244
Filed: 1954-09-24
Abstract: Ammonium sulphate preparation by mixing an aqueous solution of a double salt of calcium sulphate and ammonium sulphate with an aqueous solution of ammonium carbonate is characterized in that the ammonium carbonate solution is prepared by treating a solution of ammonium sulphate with ammonia and carbon dioxide in concentration insufficient to cause a separation of ammonium sulphate during carbonation but sufficient to lead to such separation during the reaction with the double salt.  The double salt is preferably prepared from a mixture of calcium and ammonium sulphates in water in such proportions that the ammonium sulphate solution remaining after precipitation of double salt, is suitable for the preparation of the ammonium carbonate solution. The calcium carbonate co-precipitated with the ammonium sulphate can be separated by entraining the carbonate in the flowing stream of the reaction mixture while the sulphate settles out.

Title: Improvements in and relating to the manufacture of blown hollow glassware from sheet glass
Inventor: COFFEY JAMES SELWYN KEMPTHORNE
IPC: C03B23/035
Filed: 1964-07-06
Abstract: <PICT:1072011/C1/1> Hollow glass articles are formed by transferring a sheet of heat-softened glass 20, freely resting on a support 23, to a female die 3, formed of a material of low thermal conductivity, against which it is clamped, applying differential gas pressure to force the sheet into the die, and removing, or at least indenting to facilitate subsequent removal of, the portion of the sheet outside the edges of the die.  The support 23 is lowered on to a ledge 26 on the die 3 and a sealing disc 12, preferably of stainless steel, is lowered on to the upper surface of the sheet and is maintained in sealing engagement therewith by a spring 13. Further downward movement of an upper press causes knife edges 10 to indent or shear off the outer portion of the sheet around the sealing disc 12. Compressed air is passed through nozzles 19 in the disc 12 to blow the softened sheet out to the shape of the die cavity, air vents 7 preventing build up of air bubbles in the die. To prevent thermal shock, both the female die and the sealing member are preheated by gas burners 4, 18.  After formation the article is ejected by a vertically reciprocable base-plate 5. Perforated articles may be made by blowing thin-walled bubbles of glass into recesses in the female die; after forming, these bubbles are easily broken off to leave holes.  In a modification, several articles are produced simultaneously from a single sheet, the glass being pulled into the shape of the die by suction.  The glass sheet may be embossed and decorated prior to forming.

Patent GB-1162457-A (GB)
Title: Multi-Processor System.
IPC: G06F9/50
Filed: 1968-06-12
Abstract: 1,162,457. Multi-processor computing systems. INTERNATIONAL BUSINESS MACHINES CORP. 12 June, 1968 [13 July, 1967], No. 27826/68. Heading G4A. In a multi-processor system, each processor has an associated control unit, each control unit being able to select a task from one of a plurality of task queues in a central memory. Each control unit can communicate with its associated processor and over a common bus with the other control units. Specification 1,150,110 is referred to for details of the latter communication. The (common) central memory stores not only the task queues (which may relate to batchprocessing, time sharing, diagnostic and maintenance, and interrupts &c. respectively) but also a queue status word for each queue. The status word specifies a residual quota (viz. the number of processors ideally working on tasks from this queue minus the number of processors actually currently doing so), the low order portion of the address of the first remaining task in the queue (the high order portion of the address being encoded from the identity of the queue), and the number of tasks remaining in the queue. The residual quota can be increased or decreased under manual or supervisor programme control. Each control unit includes a register specifying which queues are non-empty, and a register specifying which queues have a positive residual quota. When a processor has almost finished the task it is currently working on, its control unit selects the first queue which has a positive residual quota and is non-empty, usually starting at the queue after that the last task came from (or, as a modification, at the first queue in a predetermined priority order), using the registers mentioned. If there is no such queue, the selection is done in the same way except that the residual quotas are ignored. The first task of the selected queue is obtained from the central memory using the address portion in the queue status word, and executed by the processor. All three portions of the queue status word are updated as appropriate. The control unit updates the registers mentioned, as and when appropriate, and causes the other control units to update their corresponding registers.

Abstract: 1463246 Reactor vessels COMMISSARIAT A L'ENERGIE ATOMIQUE 2 July 1975 [30 Aug 19741 27887/75 Heading G6C A first reactor vessel 1 embedded in a horizontal top shield slab 4, e.g. of concrete, and suspended from the end portion 3 of the vessel wall 2 which forms a bond strake, is thermally protected adjacent its upper portion by rings 16, 17 fitted and compressed within the annular space 13 between a shell 9 enclosing the shield slab 4 and the opposite reactor vessel wall 2. The shield slab 4 is provided with a central projecting portion 8 which penetrates into the interior of the vessel 1 beneath the level of anchorage of the bond strake 3. Ducts 12 embedded in this portion 8 have a suitable coolant liquid circulated through them to maintain the slab 4 at a low mean temperature, e.g. 40 C. The annular space 13 is necessary to allow for dimensional variations arising from temperature differences between the vessel wall 2 and the shield slab shell 9. The wall 2 is brought to an intermediate temperature between that of the sodium within the vessel 1 and that of the bond strake 3. Thermosiphon effects within the annular space 13 are prevented by means of the rings 16, 17, each of which is formed by a series of juxtaposed elements having the shape of sectors of a torus in the embodiment illustrated in Fig. 1. Each sector before assembly comprises a fine mesh wire fabric 18 closed to form an element of cylindrical shape (Fig. 2, not shown) and filled with a packing of stainless steel wool 19. After assembly, these sectors are deformed so as to occupy zones of substantially rectangular cross-section within the annular space 13. In an alternative construction (Fig. 3, not shown), the juxtaposed elements constituting the rings are parallelpipedal elements formed by a stack of wire fabric layers (26) enclosed within a housing formed by two half-casings (27, 28) engaged one inside the other.

Filed: 1921-10-26
Abstract: 192,155. Williams, O. R., and Williams, D. D. Oct. 26, 1921. Arresting-grips or friction apparatus on permanent way.- Spring-pressed cheek rails which are connected to the running rails for stopping or retarding railway vehicles, are made in short lengths so that each wheel of the vehicle separates the cheek rail and the retarding effect is thus in part due to the work done in stressing the springs. Several methods of mounting the cheek rails are described. As shown in Fig. 1, the cheek rail 3 is directly connected to the running rails 2 by a bow-shaped spring 1, a wedge-block 4 being added if desired to adjust the stress of the spring. As shown in Fig. 5, the cheek rail 3 slides upon the rod 8 against the spring 14 the compression of which can be adjusted by the nut 15 with locking-pin 16. In another arrangement the web of the cheek rail is substantially vertical as in Fig. 1 and this rail slides upon a rod such as 8, Fig. 5, which is however pivoted to a bracket to which the running rail is secured. Figs. 8 and 9 show the cheek rail hinged to the running rail by brackets 19, 20, the spring 29 acting in tension. Adjustment of the pressure of the spring is effected by a screw 30<a> mounted on a part integral with the bracket 19 and engaging one end of the spring. In another form, the cheek rail is hinged by brackets 19, 20 and a compression spring is mounted upon a rod pivoted to the cheek rail and sliding through a guide-member integral with the bracket 19. Fig. 10 shows the cheek rails hinged at 32 to the running rails and acted upon by spring rods 34 which can be rendered ineffective by moving the plate 33 against which the rods abut. The plate can be actuated by point rodding or by a gate wheel machine or lever machine. Specification 29904/12 is referred to.
