Title: Process for the Manufacture of Sodium Tripolyphosphate with a low content of the high temperature modification
IPC: C01B25/41
Filed: 1967-07-24
Abstract: 1,155,775. Sodium tripolyphosphate. KNAPSACK A.G. 24 July, 1967 [6 Aug., 1966], No. 33957/67. Heading C1A Sodium tripolyphosphate Na 5 P 3 O 10 , containing less than 10% by wt. of the high temp. modification (Phase I) is produced in a one-step process inside a spray tower by spraying a phosphate soln. containing a max. of 0-26% by wt. sulphate ions and a max. of 0.11% by wt. foreign elements referred to P 2 0 5 , the foreign elements being comprised of any chemical elements except P, Na, O 2  and H 2  and S bound in the sulphate ion. The phosphate soln, is produced in customary manner from phosphoric acids, which are based on wet-processed crude phosphates and have been purified and neutralized to contain Na 2 O and P 2 0 5  in a ratio corresponding to that desired for the final product. Wet process phosphoric acid containing more than 0.26% by wt. sulphate and more than 0À11% by wt. foreign elements, referred to P 2 0 5  and mixed with a quantity of thermal phosphoric acid sufficient to produce a mixture containing less than 0.26% by wt. sulphate and less than 0.11 % by wt. foreign elements, referred to P 2 O 5 , may be used as the starting component. The examples describe the preparation of sodium tripolyphosphate by spraying about 30 tons of the starting material into a spray tower as described in German Specifications 1,097,421 and 1,007,748, over a period of about 3 hours. The form-I content of the product was found to be less than 7% by weight in each case. To increase the purity of the form-II content, a sample of the product may be annealed at 500‹ C. to increase the concentration of the form-I product, and then crushed and annealed at 360-380‹ C. under steam at a partial pressure of about 400 mm. Hg.

Title: Improvements in or relating to weaving looms
IPC: D03D47/00
Filed: 1959-10-07
Abstract: 934,489. Looms. A. GENTILINI. Oct. 7, 1959 [Oct. 9, 1958], No. 33979/59. Class 142 (2). A succession of shuttles, each containing weft for one pick, fall by gravity through a vertical shed and are returned to the top of the loom by a conveyer belt which takes them through a replenishing mechanism where they receive a fresh supply of weft. Shedding and beat up occur in wave-like manner so that several shuttles lay weft simultaneously. Replenishing shuttles, Fig. 18a.-A conveyer belt 45 lifts the spent shuttles 20 from the bottom of the loom and takes them round a feeder wheel 50 where each shuttle enters a recess 32. A measured length of yarn is paid out from a spool 53 by a roller 53<SP>1</SP> driven by a friction wheel rolling on a track 51<SP>1</SP>; at the same time, a hollow spoke 52 of the feeder wheel registers with a suction port in the shaft on which the feeder wheel rotates, whereby suction is applied to the interior of the shuttle through perforations in its body (see also Fig. 15) to draw the yarn into the shuttle. As the shuttle leaves the feeder wheel to enter a guide 54<SP>1</SP> leading to the shed, the yarn is cut by a blade 54. There may be two feeder wheels, some shuttles being replenished by one and some by the other to provide weft patterning. Shedding mechanism.-Healds 1, 3, Fig. 4, attached to levers 5, 7 and healds 2, 4 attached to levers 6, 8 are moved oppositely by cams 16 which are disposed helically along their shaft so that the shed is progressively opened and closed as the shuttles descend. The oppositely moving heads may be coupled together by cords passing round pulleys and are then operated by levers 8 only. Alternatively, as shown in Fig. 25, the healds may be operated by the conveyer belt 45 which has cam grooves engaged by rollers 67 on bell-crank levers 8. Beat up mechanism.-Pivoted reed teeth 14, Fig. 4, may be operated by cams 19 disposed helically along their shaft to give the required undulating beat-up action. Alternatively, a groove 41 in the conveyer 45, Fig. 25, may actuate rollers 70 on stirrups 25 which impart undulatory movements to a flexible reed 24; or the stirrups 25 may be actuated by the cams 19, Fig. 4. In another form, Fig. 22, the warp and fabric pass round rollers having a flexible surface 66 (which rotates slowly as the fabric is taken up) mounted on eccentric supports 65 rotated by a shaft 62; the ensuing wave-like distortion of the roller draws the warp backwards and forwards against a fixed reed. Flexible reed, Fig. 14.-Reed wires 30 are spaced by springs 33 and have apertures through which wires 32 are threaded; the assembly is then embedded in rubber or like baulks 34. Selvedges. A true selvedge may be formed at the top edge of the fabric by omitting to cut the weft between two shuttles of a pair, whereby when the shed has been changed after entry of the first shuttle, the weft is looped round the end warp thread in the usual way as the second shuttle enters its shed.

Title: Improvements in coupling arrangements comprising amplifying tubes
IPC: H04B1/10
Filed: 1930-11-12
Abstract: 360,679. Valve amplifying circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Nov. 12, 1930, No. 34083. Convention date, May 19, [Class 40 (v).] In order to eliminate disturbances due to local induction, "pick-up," or reaction, when using a thermionic amplifier of the indirectly-heated type, the ordinary circuit arrangement shown in the Figure is modified by omitting the earth connection 7 from the cathode 4. This limits the coupling between the cathode and the current-source to the small capacity existing between the heating element 5 and the cathode 4, which has a high impedance to any low-frequency disturbance. The arrangement is advantageous when applied to the valves of a preliminary amplifier, or to the first valves of a cascade series, heated from an alternating or direct current source. Specifications 219,705, 338,107, [both in Class 40 (v), Wireless signalling &c.], and 340,399, [Group XXXII], are referred to.

Title: Improvements in or relating to machines for setting projectile fuzes
IPC: F42C17/00
Filed: 1933-12-11
Abstract: 414,276. Fuze - setting apparatus. RHEINISCHE METALLWAAREN-UND MASCHINENFABRIK, 195, Ulmenstrasse, Derendorf, Dusseldorf, Germany. Dec. 11, 1933, No. 34804. Convention date, Jan. 11. [Class 9 (i).] In automatic fuze-setting machines, a signal is actuated in dependence on the depth of insertion of the projectile in the setting socket, the signal being either displayed or interrupted when the projectile is correctly positioned. In one form of apparatus, the nose of the projectile seats on a plunger k, Fig. 1, and depresses it against spring pressure. If the descent is sufficient to ensure that a pawl b in the setting-socket B will correctly engage with the fuze ring, a surface k<1>1 displaces a pawl b2 which releases a rod e<1> and allows the ring E to descend to actuate a projectile locking device b, this movement also displacing a signal Z from a viewing aperture by means of a lever z and toothed sector t. The clutch ring, D is engaged with the driver c in known manner to drive the socket B and, after the fuze is timed, the ring D rises to disengage the socket B from the driver and to re-set the signal Z in the viewing aperture. According to a modification, the signal appears in the viewing aperture only when the fuze ring is in correct timing position. In this modification, the piston k, Fig. 4, on its descent rocks a sleeve r5 by means of a forked bar k2 and pin r9 thereby compressing a spring r8<SP>1> by means of a helical groove in the sleeve r5 engaging a pin r6' When the piston k descends far enough to ensure correct setting of the fuze ring, a stop v9<SP>1>, Fig. 5, on the arm rocked by the pin r9 actuates a lever w1 on a spindle w which is thereby rocked and disengages a stop w2, Fig. 6, from a pin r4, this pin passing through a slidable plunger r2 forming an abutment for the spring r8<SP>1>. On the release of the pin r2 from the stop w2, Fig. 3, the plunger r2 is moved forward by the compressed spring r8<SP>1> and causes a wedge r, vertically slidable in the front of the plunger r2, to separate the aligned parts e2 of the rod controlling the actuation of the signal. On the removal of the projectile, the piston k rises and re-sets the apparatus. Specification 334,550, [Class 9 (i)], is referred to.

Title: Improvements in or relating to processes for the application of firmly adhering metal coatings to ceramic bodies
IPC: C04B37/02
Filed: 1937-12-20
Abstract: 508,014. Uniting metal to ceramic material; couplings. S I E M E N S - SCHUCKERTWERKE AKT.-GES. Dec. 20, 1937, No. 35268. Convention date, Dec. 19, 1936. [Classes 36 and 38 (i)] [Also in Groups II and XI] To enable a metal member to be soldered or welded to a ceramic body, the latter is metallized by first heating to a temperature at or near and preferably immediately below the fusing point of the metal to be applied and is then coated with the metal by-spraying, e.g. by the Schoop process. The coating applied by spraying may 'be thin and may be thickened by other means, e.g. electrolysis. In the preferred method a non-metallic intermediate layer, e.g. a glaze, is first applied to the ceramic body, this layer having a softening point which lies below the fusing temperature of the metal coating, so that it is softened during the preheating. The softening temperature of the glaze should preferably be above the fusing temperature of the solder to be used in joining the metal member to the metallized ceramic body. The process may be used in manufacturing heating resistances, e.g. for electric ovens, the heating conductor being surrounded by a ceramic tube rendered gas-tight by baking and which is metallized by the process described to enable motal end seals or closing members to be joined thereto in a gas-tight manner. It may also be applied to the production of gas-tight seals for ceramic vacuum vessels, e.g. discharge tubes or vacuum switches. The Specification as open to inspection under Sect. 91 described also the construction of heating elements for electric ovens, including the means for coupling the resistance element to the terminal, which forms the subject-matter of Specification 507,846. This subject-matter does not appear in the Specification as accepted.
