IPC: B29C65/18
Filed: 1961-09-13
Abstract: 1,048,491. Closing filled packages; preserving contents of packages. AUTOPRUFE Ltd. Dec. 13, 1962 [Sept. 13, 1961], No.32780/61. Heading B8C. [Also in Division B5] Apparatus for thermo welding plastics materials comprises two jaws 16, 19 the jaw 16 being movable towards and away from the jaw 19, a jaw moving member 15 operable to close the jaws by means of an electromagnetic device, and means for controlling the supply of welding current to the jaws in accordance with the position of the latter so that such current is supplied only when the jaws 16, 19 are closed. The member 15 extends through a slot 14 in an outer-casing 10 to which a plate 16 having an edge 18 forming the gripping edge of the movable jaw is attached. The jaw 19 comprises a plate secured to the base 11 of the casing 10. The apparatus includes an inner casing 21 secured to the casing 10 and having a slot 24 registering with the slot 14. The member 15 is of channel shape cross-section over a major part of its length and a spindle 26 extends through an aperture in each of its side flanges 25. The spindle 26 is mounted in the casing 21 by ball bearing assemblies 27 (Fig. 3, not shown). A leaf spring 30 bears on the inside of the channel formed by the member 15 and against a boss 31 on the casing 21 and tends to open the jaws 16, 19. The member 15 is attached to the armature 34 of a solenoid 35 by two leaf springs 36 fitted in diametrical slots in the ends of a pin 41 mounted on the armature 34. Movement of the armature 34 upwardly causes movement of the member 15 about the pivot 26 to close the jaws 16, 19. This movement also causes a pin 43 on the member 15 to move the operating member 42 of a microswitch 38 to supply high frequency current to the jaws 16, 19. Alternatively, both the solenoid circuit and the circuit for the jaws may be controlled by the switch 38. In a modification, not shown, two micro-switches are pro vided and the circuits are connected to the member 15 and the fixed jaw 19, each jaw being heated to the welding temperature by the current supplied thereto. An automatic control circuit including a time delay mechanism may be incorporated in the apparatus whereby the circuits may be energized in timed relation. The apparatus may be arranged to operate intermittently in timed relation to apparatus for feeding containers between the jaws and removing them after welding. The apparatus is similar to that described in Specification 1,048,492.

Abstract: 1,083,649 Cooling garments. UNITED AIRCRAFT CORPORATION. Aug. 3, 1965 [Sept. 4, 1964], No. 33042/65. Heading A3V. A cooling garment comprises a fabric layer supporting a plurality of cooling tubes in contact with the wearer's body, the arrangement of the tubes being such that their cooling effect in any area of the body is substantially proportional to the body mass in that area. The fabric is preferably net with the major axes of the meshes at an angle of 45 degrees to the major axes of the garment to allow a degree of two-way stretch. As shown, a one-piece suit comprises front and back portions laced at 31 along the outer edges of the torso, arms and legs, the latter having knitted cuffs 16 and zip fasteners 28 along their inner sides.

Patent GB-926120-A (GB)
Title: Vibratory apparatus with tuned drive
Inventor: CARRIER ROBERT MOORHEAD
IPC: B65G27/28
Filed: 1959-09-30
Abstract: 926,120. Vibratory mechanism. CHAIN BELL CO. Sept. 30, 1959, No. 33218/59. Class 80 (4). A member 10, which co-operates with a first tuned resilient system, for example, 13, having a natural frequency at a predetermined operating speed, is vibrated by a fixed amplitude exciter, such as an eccentric 18, which is also coupled to the member 10 by a second tuned resilient system, for example 25, 26, also resilient in the operating speed range, and constituting a vibration absorber, which serves, when resonant, to stabilize the reaction point, for example the eccentric axis, of the force-transmitting system. The maximum amplitude of the vibrated member 10 is thus determined by the throw of the eccentric 18 and cannot increase to excessive values outside the resilient speed range (e.g. during starting), since under such conditions the tuned absorber can permit the reaction point to yield. Destructive amplitudes possible with eccentric mass exciters are also avoided. In Fig. 1, the eccentric 18 hangs on a link 19 from the vibrated member 10, itself supported on springs 11, and is also belt-driven by a fixed motor 21. The first tuned system comprises a spring 13, eccentric connecting-rod 17 and dependent mass 15, whilst the second tuned system, the absorber, comprises a spring 25, dependent mass 26, and adjustably positioned mass 28. At the resonant speed the axis of the eccentric 18 is stationed in space by the absorber and forms the reaction point for force transmission through the connecting-rod 17 and the first tuned system to vibrate the member 10. In Fig. 2, not shown, the vibrated member is supported above a fixed base on inclined blade springs, and is connected to the base by a pair of helical springs, at right-angles to the blade springs and constituting with the member, the first tuned system. Both motor and eccentric are fixed to the base and the eccentric connecting rod is pivoted to an intermediate point of a resilient lever pivoted to the vibrated member and carrying at its lower end a mass, which with the resilient lever constitutes a tuned absorber, the mass becoming substantially stationary in space at resonant speed, to form the reaction point for the lever. Fig. 3, not shown, is similar, but the eccentric oscillated lever is non-resilient and is connected through a spring to a mass depending from the vibrated member.

Title: Improvements in or relating to a method of lowering the tendency towards setting of potassium nitrate and potassium nitrate of free-flowing form with a reduced tendency to setting
IPC: C01D9/20
Filed: 1948-12-29
Abstract: Non-cohering free-flowing potassium nitrate crystals are produced by depositing on the surfaces of the crystals, by evaporation from aqueous solution, a dyestuff of sulphonated aromatic character such that when dissolved in a hot saturated aqueous solution of the nitrate, the crystals which begin to appear on cooling are in thin fragile plate-like form.  0.01-0.10 parts dyestuff per 100 parts nitrate may be used.  In examples: (1) the nitrate is crystallized by cooling a saturated solution at 40 DEG  C. containing a dyestuff, and the crystals with adhering mother liquor are dried; (2) ground nitrate is mixed with an aqueous solution of a dyestuff and dried; (3) a solution of a dye is sprayed over wet small crystals, and the mixture dried. Particularly suitable dyestuffs are 1 : 4-diaminoanthraquinone - 2 - sodium - sulphonate and 1 : 4 : 5 : 8-tetramino-anthraquinone disulphonic acid (sodium salt); other examples are listed.

Abstract: 1,025,498. Seals. DRESSER INDUSTRIES Inc. Aug. 17, 1964 [Aug. 23, 1963], No. 33500/64. Heading F2B. A seal for a centrifugal compressor circulating helium in a nuclear plant comprises a ring 29 surrounding the impeller shaft 14, a set of annular labyrinth seal elements 46, 49 extending radially inwardly towards the impeller shaft, abutment elements 44 at opposite ends of the set of seal elements 46, 49 to provide land surfaces which are normally spaced from the shaft and seal means operatively interposed between the ring 29 and casing 19. The abutment elements 44 may extend as far as, or further than, the seal elements towards a sleeve 30 which is rotatable with the impeller shaft. The ring 29 is frictionally held in position by a portion of the ring having a radial surface 62 which is pressed by a spring 68 against a radial surface 63 of a ring 58 secured to the casing 19, piston-type split-rings 54, 55 allowing radial movement of the ring in operation; the spring 68 is of waveform and is retained in a recess by a ring 64. Helium sealing gas at a greater pressure than the gas being compressed is supplied to the seal (designated 28 in Fig. 1, not shown) through a pipe (73) and duct 71 to a space 72 between the split-rings 54, 55 from where it flows inwardly through bores 76 and in both axial directions between the seal elements 46, 49 and the sleeve 30; a portion of the sealing gas will leak past the split-rings and a further portion past abutments 32, 33 of the sleeve. The sealing gas which flows past the seal elements 46 enters the impeller chamber 15 and the sealing gas which flows past the seal elements 49 enters drain passages 78, 79 and return pipe (80). When the compressor is shut down, a seal is provided between a flange 81 on the impeller shaft and an element 83 on a bellows assembly 84. The sealing gas serves also to cool the ring 29. The invention may also be applied to apparatus for circulating liquid and, if desired, the sealing fluid may be liquid instead of gas.
