Title: Improvements in or relating to cartons
IPC: B65D5/50

Abstract: 1,133,838. Cartons. LUMALAMPAN A.B. 23 Feb., 1966 [24 Feb., 1965], No. 7935/66. Heading B8P. A carton of plastics, cardboard, &c., for two or more electric light bulbs includes a flexible partition 8 which separates and supports the bulbs, and is connected to two opposite faces 2, 2<SP>1</SP> of the carton by flaps 11, 12/12<SP>1</SP>, one of which, 11, is spaced from the partition 8 by a section which lies against but is unattached to the greater part of the corresponding face 2<SP>1</SP>. In the embodiment shown two bulbs are inserted from either end of the carton with their smaller ends projecting in opposite directions, the larger ends pressing against the partition 8 which is provided with a central slit 10 to enable opposite halves of the partition to flex in opposite directions to accommodate the bulbs in staggered relationship. The partition 8 is provided with lateral score lines to assist in this flexing motion, which is further facilitated by the folding of the unattached section away from the face 2<SP>1</SP> (see Fig. 3, not shown). The partition 8 tapers across the width of the carton, having its narrow end adjacent the flaps 12, 12<SP>1</SP>. The carton is made from the blank of Fig. 1 (not shown), in which the partition (8), and the flaps (11, 12, &c.) are formed as an extension to the face (1). Flaps (2<SP>11</SP>, 3 and 4, 5) on the faces (1, 1<SP>1</SP>) respectively, together with flaps (6, 6<SP>1</SP> and 7, 7<SP>1</SP>) on faces (2, 2<SP>1</SP>) respectively provide the means for closing opposite ends of the carton. A carton for containing several bulbs may be formed with more than one spaced flexible partition, for example by modifying the partition section (8) of the blank of Fig. 1 (not shown), to provide further tapered portions capable of being folded into additional partitions within the carton.

Title: Improvements in or relating to machines for breaking, softening, and scutching fibrous materials
IPC: D01B1/30
Filed: 1922-03-18
Abstract: 192,315. Boby, Ltd., R., and Griffiths, C. H. March 18, 1922. Breaking and scutching apparatus.-A machine for breaking, softening, and scutching flax, hemp, or ramie, and of the kind in which the material is first fed between a grid and breaking rollers on a rotary main cylinder and is afterwards withdrawn by reversing the mechanism, is provided with rotary plain or comb bars 28, 29, 30, which are driven by gearing from the main cylinder 2 and pass in succession across the grid 7 to draw the fibres therefrom immediately a breaking-roller 4 has left the grid. Cross-shaped combs 6 precede the rollers 4 and revolve with the cylinder, the fibres being thus combed or scraped on opposite sides. The grid is substantially vertical. In a modification, the bars 28, 29, 30 are spring-supported, and are caused to follow the contour of the grid by a cam-guide at each side of the machine.

Abstract: 750,905. Linkwork. TIMSONS, Ltd. March 25, 1954 [March 24, 1953], No. 8093/53. Class 80(3) Linkwork particularly applicable to operating certain of the printing rollers of a printing machine according to Specification 750,902 [Group XVI], independently of others comprises a lever 13 coupled at one end to a rod 16 for operating the said rollers and at the other end to a link 18. The opposite end of link 18 carries a stop pin 19 forming an abutment for a sliding block 20 pivotally connected to a manual control lever 22. Intermediate its ends the link 18 has a stud 30 on which a coupling block 29 is rotatably mounted and this block 29 is adapted to slide in a guideway 28 on a lever 26 which is coupled at 24 to the main clutch throwoff mechanism. The guideway 28 has one long wall 31 and a short wall 32 so that in the position shown in Fig. 1, the rod 16 is under control of the main clutch mechanism and the rollers are thrown-on, the hand control 22 being inoperative. If the hand control 22 is moved clockwise to the position shown in Fig. 2, the block 20 slides along the link 18 to engage the stop pin 19 and link 18 is also moved clockwise to bring the coupling block 29 clear of the short wall 32 of the guideway. Further movement of the hand control 22 will then move link 18 longitudinally to operate lever 13 and the rod 16 to override the main control and throw-off the rollers, the coupling. block 29' moving clear. of the guideway 28. Return movement of the hand control 22 will rotate the link 18 anti-clockwise and allow it to move to the left to re-engage the coupling block 29 in the guideway 28 to restore the main control.

Title: Improvements in and relating to electric switches suitable for carrying heavy currents
IPC: H01H1/54
Filed: 1943-05-21
Abstract: 565,823. Switches partly electromagnetic ; switch contacts ; arcrupturing in switches. BRITISH THOMSON-HOUSTON CO., Ltd. May 21, 1943, No. 8114. Convention date, May 21, 1942. [Class 38 (v)] In a high-speed circuit-breaker employing the loop-effect for reinforcing contact-pressure with heavy currents and accelerating the opening movement on fault, the movable contactmember f5 is urged by springs 67 against a cylindrical surface 18 connected to a terminal block 10 and has contact surfaces 29, 38 cooperating with main and arcing contacts 16, 17 respectively. The contact 16 preferably comprises three separated members, the intermediate one of which breaks last, and each member makes line contact in a recess 24 in a block 23 connected to terminal block 11 and is urged outwardly by a spring bolt 25 insulated at 27, 30 from the blocks 11, 23. Contact 17 is similarly mounted in a recess 33 in a block 34 which is insulated at 35 from direct contact with block 23 but connected to terminal block 11 over a blow-out coil 40. A spring 36 acting on insulating plug 37 urges contact 17 outwardly. Contacts 16, 17 co-operating 'with arm 15 thus constitute two parallel loops, the expansion of which, on heavy currents and right up to the moment of separation, reinforces the contact-pressure and holds arm 15 firmly against surface 18, and when the breaker opens accelerates the opening movement. An arcing- horn 43 is connected by a blow-out coil 41 and flexible lead 44 to block 10. The contactmember 15 may be constructed as in Specification 552,694, of a number of relatively thin, similar contacts. Automatic circuit-breakers.-The arm 15 is pivoted at 22 to a cradle 21 pivoted at an axis lying on the surface 18, and carries a roller 51 co-operating with a retaining roller 50 on a link 55 pivoted at 56 to an operating member 54. The opening bias of springs 67 urges link 55 to the right and urges member 54 in a clockwise direction about its pivot 52 so that a part 58 thereon bears at 59 against the frame 48. Roller 50 also bears on a surface 53 of a retaining member 46 which is pivoted at 52 and retained in turn by a latch 47 pivoted at 49. Springs 61, 62 are adapted to restore the member 46 and latch 47, respectively, into operative position after tripping, the former being anchored to the member 46 and frame, respectively, at 63, 64. A pin 66 and slotted link 65 limit the relative movements of the member and latch, and a spring 70 anchored between the arm 15 and member 54 positions the latter ready for reclosure. Where several such breakers control the several anode circuits of a mercury-arc rectifier, a common reclosing bar 73 may be secured to the U-shaped reclosing levers 72, each of which has an adjustable projection 75 adapted to bear on the parts 58' of, the members 52 of such of the breakers as have been tripped.

Title: An improved process for purifying, enriching or refining crude graphite
IPC: C01B31/04
Filed: 1925-03-26
Abstract: To remove the siliceous and other impurities present in crude graphite the latter is crushed, triturated in a moist condition, sieved in the presence of water and finally subjected to a flotation process.  The trituration is preferably effected by means of metal cones, sufficient water being added to form the graphite into a paste.  Silica and the aluminium and iron oxides present are reduced to a finely divided condition and may be separated from the larger particles of graphite by means of a pneumatically-operated vibrating sieve provided with a metallic net.  While the graphite is being sieved it is sprayed with water. After sieving, the graphite is further purified by flotation, the coarser particles being returned to the triturating apparatus. When a greater degree of purity is required, the graphite after treatment as above described is heated to about 700 DEG  C. in a kiln with sodium carbonate and the product either triturated, sieved &c. as before, or is treated with dilute acid, for example hydrochloric acid, and washed with water to remove the excess acid and soluble matter, the resulting purified graphite and very finely divided silica being separated by sieving in the presence of water.
