Filed: 1973-01-16
Abstract: 1452481 Sodium-sulphur cell BRITISH RAILWAYS BOARD 11 Jan 1974 [16 Jan 1973 19 March 1973] 2267/73 and 12999/73 Heading H1B A sodium-sulphur cell comprises an inner tubular member 1 and an outer tubular member 2, both closed at one end, the other end being closed by a compression seal assembly comprising a flange 8 on tube 1, which engages a flange 9 on tube 2 via a sealing ring 10. The inner tube 1 is closed by member 11 which has a rim 12 engaging flange 8 through gasket 21, the assembly being compressed by member 13 which engages rim 12 through washer 22 and is spot welded to tube 2 at 14. Tube 1 constitutes the electrolyte and may consist of beta alumina and contain sodium, while tube 2 of e.g. stainless steel contains sulphur which may be introduced through an aluminium negative electrode tube 15. Metal wool 3 and stainless steel plate 24 help 15 distribute the liquid sodium over the inner surface of tube 1. Flange 8 may consist of alpha-alumina, ring 10 of aluminium or grafoil, gasket 21 of aluminium, and washer 22 of mica or asbestos. In another embodiment, Fig.2 (not shown), the metal wool is omitted.
Patent GB-687693-A (GB)
Title: Process and device for producing a set of colours for shaded tone colour printing
IPC: D06B11/00
Filed: 1951-01-30
Abstract: 687,693. Printing processes; inking-apparatus. SMEJDA, R. Jan. 30, 1951 [Feb. 6, 1950], No. 2274/51. Class 100 (ii). In multicolour printing, e.g. on textiles, shaded colour tones (ombrÚ colours) are obtained by placing the unmixed " colours " (one of which may be a colourless binding means) into a rectangular box, the colours being separated by a partition wall or walls running generally longitudinally of the box and shaped to divide the box according to the colour proportions desired at each point therealong, then subdividing the contents by parallel separating walls running transversely to the box, and finally mixing the colours between each pair of subdividing walls and feeding them to the printing device. The invention may be applied to screen or roller printing. Unmixed colours may be poured into the respective compartments of a colour box 1 (Fig. 2) of length equal to the total printing width and having removable walls 3 and 5 held in place by split plugs 4, the wall 5 being bent according to a graph on which the printing widths are plotted as abscissae and the colour percentages as ordinates; an indicator 5a ensures equal levels. The wall 5 is then removed, and a dividing comb (Fig. 3) having parallel sheet metal walls 6 is pressed into the box. Removal of the wall 3 then allows the colours to run into the corresponding compartments of a storage tank 10 where they are mixed by a comb 13. The mixed colours are then fed as required to the head piece 15 (Fig. 6), clamped to the printing machine, the sections of which have outlets 18 controlled by a slide 19. In modifications the wall 3 of the colour box 1 is fixed and the base either is grate-shaped with bars corresponding to the walls 11 of the tank 10, the spaces between the bars being closed by removable or tiltable strips, or has sieve-like apertures all closed by a single slide; in both cases the dividing comb is dispensed with.

Abstract: 1491352 Boring earth &c. FRIED KRUPP HUTTENWERKE AG 20 Jan 1975 [29 Jan 1974] 2302/75 Heading E1F A rotary drill bit has at least one cutting system consisting of a pair of cutting elements arranged so that one corner of each of the cutting elements makes a cut across the central region of the cut produced by the other cutting element. As described a core bit has a pair of triangular inserts 4, 5 which are clamped to the body of the bit by clamps 6, 7, the inserts having three cutting edges, each of which can be brought into an operative position as the others become blunted. The bit is also provided with hard metal supports 12, 13 which bear against the wall of the hole being drilled. The inserts 4, 5 (Fig. 3) are arranged so that the corner 17 of insert 4 projects beyond the centre of cutting edge 15 of insert 5, and so that the corner 16 of insert 5 projects beyond the centre of cutting edge 14 of insert 4. In this way the cut is divided into four zones I to IV (Fig. 7) which reduces the size of the shavings to facilitate the removal of debris by the flushing medium. In a modification (not shown) the cutting inserts may be of rectangular or trapezoidal shape. The invention may also be applied to full drill bits, in which case more than one such cutting system may be necessary.

Title: Improvements in preventing struvite formation in thermally treated seafoods
IPC: A23B4/02
Filed: 1958-01-27
Abstract: Struvite formation in the thermal treatment and canning of sea foods which are subject to the accumulation of struvite crystals, is prevented by introducing into the can 0.025 to 0.2 per cent of aluminium sulphate, Al2(SO4)3.18H2O, based on the combined weight of sea food and brine or water in the can. The aluminium sulphate may be introduced dissolved in water, as powder or tablet.  According to an example, a 4.86 grams salt tablet containing 200 milligrams of the crystalline aluminium sulphate was added to a 200-gram tin can, followed by 128 grams solid shrimp and 72 grams water; the filled can was sealed under vacuum and heat-treated.  Struvite-forming sea foods referred to are shrimp, crayfish, lobsters, the King and Dungeness crabs of the Pacific Ocean, fish such as tuna, bonita, salmon and the cod family.

Title: Digital wrist watch

Filed: 1973-01-18
Abstract: 1391235 Electronic watches SUWA SEIKOSHA K K 18 Jan 1973 [22 Jan 1972(3)] 2700/73 Heading G3T A digital electronic watch, e.g. having a liquid crystal or light-emitting diode display, is selectively operable either to indicate the passing time of day or perform a timer function. In Fig.2 a crystal controlled oscillator 11 output is applied to a counter divider 12 which produces timing signals at 1Hz. Counting circuits 13, 14, 15 send BCD coded signals corresponding to seconds, minutes and hours signals respectively, to the input of a selecting circuit 19. The circuit 19 as part of the timer function also receives further BCD coded signals from memory circuits 16, 17 which 'memorize' either the hours and minutes digits of a predetermined time period at the end of which an alarm is to operate or the hours and minutes digits of a predetermined time at which the alarm is to operate. A selector switch S3 is operable to enable the circuit 19 to select either set of the said BCD coded signals and send the selected signals to a distribution circuit 20 which transforms them into suitable form for operating a digital display (not shown). Thus the display will indicate either time of day or the setting of the timer. For timer operation a coincidence gate 18 senses coincidence between the BCD coded signals from the memory circuits and from the time counting circuits and sends a signal via an amplifier A to an alarm SP, e.g. a buzzer or speaker. Switches S 1 ,S 2  perform a dual function. When S 3  is in one position they are usable to set or correct the passing time of day displayed. When S 3  is in its other position they are used to set the predetermined time or predetermined period. A switch S 5  is provided to start or stop counting by the counting circuit 12 thus enabling correction of the seconds indication. A switch S 4  is a reset switch to reset the display to zero. Where the memory circuits memorize the time period they include subtractors to subtract from the predetermined period the passage of time.
