Title: Improvements in Ropes for use as Lifting Slings.
Inventor: BULLIVANT FREDERICK ARTHUR
IPC: B66C1/18
Filed: 1913-11-18
Granted: 1914-10-15
Abstract: 26,470. Bullivant, F. A., and Selby, G. M. Nov. 18. [Addition to 24,036/11.] Flat ropes.-Wire and like ropes of the kind described in the parent Specification, for use as lifting-slings, are according to the present invention made of two or more strands, one or more of which have the component wires &c. twisted righthand and the other have the wires &c. twisted lefthand, by arranging the strands to form a number of close parallel loops with lengths of right-hand strand alternating with lengths of left-hand strand, the length of the loops being approximately equal to that of the sling, and the number of the loops in accordance with its required width. The sling at this stage resembles an endless flat belt, and is completed by bringing portions of the upper and lower runs side by side into one plane so that lefthand strands alternate with right-hand strands, loops being thus left at the ends for the reception of the hauling-rope attachments. The strands are secured in this position by lacing or stitching. The whole flat portion may be encased in leather &c., or the strands may be covered with hemp or other fibre &c., or pleated. The sling may be formed of loops of cables instead of loops of strands ; or a single length of strand or cable may be employed. Figs. 1 and 2 show a portion of a sling made of two strands 1, 2, one right-hand and the other left-hand, secured together by lacing- wires 5.

Title: Improved Devices for Braking Alternating Current Commutator Motors.
IPC: H02K27/20
Filed: 1914-01-05
Granted: 1915-07-15
Abstract: 299. Siemens-Schuckertwerke. Jan. 4,1913, [Convention date]. Alternating-current com-. mutator machines.-In the regenerative braking of alternating-current commutator motors, the magnetic saturation of the motor or of an electromagnetic circuit connected therewith is increased automatically as the brushes are displaced from the motoring to the braking position. In one example, Fig. 1, the lever d for moving the brushes from the motoring position F into the braking position Br is coupled to, a hand-lever h, which at the same time actuates, a switch s to reduce the number of turns of the stator winding st, which is connected to the mains n. The turns of a transformer may. be.altered instead of the stator winding, or the increase in the magnetic saturation may be effected by increasing the voltage applied to the stator winding. In polyphase motors, switchcontacts b, c, f are used. in each phase. Alternatively, the magnetic reluctance of the machine or of a connected electro-magnetic circuit may be reduced, simultaneously with the brush-displacement. In braking crane motors which return power to the mains when the load is being lowered, the switch-contacts, may be actuated automatically by a friction device on the shaft of the machine. The invention may be applied to traction motors and to motors with single or double sets of brushes:

Roasting granular substances; conditioning grain. -Ovens stated to be applicable for calcining earth, cooking grain, conditioning wheat, &c. are made of interchangeable units or sections each of which is built up of stock parts. Each section of the oven casing consists of standards A, Fig. 7, transverse parts B, walls C<3>, Fig. 2, a roof G, and a floor C<2>, each of which is made in stock sizes and forms. The oven proper consists of side walls D with angle-irons E for the attachment removably of the top and bottom pieces D<1>, D<2>, which have angleirons for attaching them to the similar pieces of the next section, packing being placed in the joints. The angle-irons E' similarly connect the side walls D of adjacent sections. The ovens are heated by gas burners F<1>, Fig. 2, in pockets f, f<1> in the pieces D', D<2>, or by oil flames from injectors at the sides of the oven burning in combustion chambers beneath it. The pockets f, f' may be separate from the roof and floor of the oven proper, and may have dampers to allow some of the combustion products to pass into the oven. The roof D' and floor D<2> consist of metal sheets corrugated or otherwise stiffened or of sheets partly corrugated to increase heat radiation, and for low temperature ovens may be tiled or enamelled. The sections or units are connected oy straps c<4>, Fig. 2. A flue H, Fig. 7, conducts the gases away from the oven proper. The walls of the casing consist of composite sheets of steel alternating with refractory materials held together by expanded metal, and the spaces between the casing and the oven proper may be filled up with slag wool. In large ovens, the materials to be treated are conveyed through the ovens by pans, trays, or buckets, on endless chains which run on girders or supports K at the sides and if necessary a similar support K<1> in the centre line of the oven. The idle parts of the chain run on guides N, Fig. 8, in hot chambers beneath the oven chamber, so that they are kept warm; also they keep taut the parts within the oven. One or more sections of such ovens may be arranged to cool the charge.

Abstract: 2025. Simmen, P. J. Feb. 8. [Addition to 27,474/13.] Electrical systems, non-automatic; track apparatus actuating signals on trains.-The system described in the parent Specification is modified so as to give three signals on the train according as a relay having a polarized and a non-polarized armature is energized or deenergized. The shoe 26, when on a rail 8, breaks the holding-circuit of the magnet 29, which remains energized, after passing a ramp, by current from the battery 57 passing through reversing-switch contacts 40. 400 on the polarized armature 35 so as to maintain this armature in the position to which it was moved by the last current received from a rail 8. The hell 52 is sounded each time the circuit from the contact 28 is broken by the movement of the shoe. The non-polarized armature 34 is raised so long as the magnet 29 is energized. When a positive current is received from the rail 8, the armature 35 takes the dotted-line position, and the lamp 81 is energized through the armature 34 and contacts 36, 39. A negative current causes the armature 35 to move to the full-line position, and a contact 390 puts a lamp 45 in circuit. When no current passes through the magnet 29, the armature 34 drops and puts a lamp 46 in circuit. The switch 56 enables the lamps 45, 81 to be interchanged when required.
