Patent GB-189720604-A (GB)
Title: Improvements in Warp Stop Motions for Looms for Weaving.
Inventor: HATTERSLEY RICHARD LONGDEN
Filed: 1897-09-08
Granted: 1898-09-03
Abstract: 20,604. Hattersley, R. L., and Jackson, S. Sept. 8. Loom stop-motions.-When a warp thread breaks, a current of air from the perforated tube 3, Fig. 1, blows the broken end against a card-covered roller 5, driven lightly by a bowl 10 resting at the bottom of a double incline 9. The thread puts a drag upon the roller and causes the bowl to travel up the incline, thereby shifting the roller laterally against a catch 14 on a stud 15. This action shifts the piece 16, mounted on the same stud 15 and provided with a weighted arm 21, and by means of the arm 17 transfers the motion to the ordinary knocking-off motion of the loom. A catch 19 on the piece 16 drops behind the spring 20, which normally presses against the end of the roller gudgeon 6, and a pin 24 on the piece also pushes the spring back. The current of air is produced by forcing air into the tube 3, or by means of a roller 25, Fig. 6, provided with strips of cloth 27 and rotate,l either in a tube 26 or in the open.

Title: Improvements in Circuit Breakers for Three Wire Electricity Distribution Systems.
Filed: 1898-09-20
Granted: 1899-01-07
Abstract: 19,940. British Thomson - Houston Co., [Hewlett, E. M.]. Sept. 20. Cut-outs; switches.-Relates to a means for breaking the main circuit in a three-wire system should one of the outer wires become grounded, or in case of excessive load on either side of the system. Fig. 1 shows the connections. A second coil D<1>, in shunt, is added to the usual series coil D of a circuit-breaker CB. Normally this shunt circuit is broken at B. A relay or double-wound magnet has its coils d, d' connected to the system as shown. Should a ground occur, the current fails in one of the coils, the armature is attracted, and contact made at H. The circuit-breaker CB then operates. Fig. 2 shows the construction of the apparatus, which is of a well-known type. Contact is made by means of a toggle-lever P held up by a pawl 0 on the armature engaging a catch o. The apparatus is adapted for other uses than merely a cut-out in case of grounding, e.g., the circuit of the coil D<1> may be closed by a handswitch situated at any part of the station.

Patent GB-189827567-A (GB)
Title: Improvements in and relating to Granite, Stone, and Marble Sawing Machinery.
Inventor: PEARSON JAMES TOWNSLEY
IPC: B28D1/04
Filed: 1898-12-31
Granted: 1899-12-23
Abstract: 27,567. Pearson, J. T. Dec. 31. Sawing granite, marble, etc.; saws.-A circular saw 6 is connected by Ranges to the overhanging end of a shaft 5 mounted on a slide block 3, which is adjustable on the bed 1 by a worm-wheel or pinion on the shaft 16<a> engaging a rack under the slide. The shaft 16<a> is driven by a hand-wheel 17 and gearing. Steadying- pegs for the saw are adjustably mounted in the saw guard, which is supported on the slide block. The stone is carried on a trolley 19 which has two racks 21, 21<a> on each side as shown in Fig. 1<A>. A pinion 23, carried by a clutch sleeve 25, is movable on the squared end of the shaft 24 by a handlever 26 so as to gear with one of the racks for feed or return. The shaft 24 is driven by bevel gear from a shaft 44, which is driven at a low speed by worm gearing 41 and stepped pulleys 39, 37, or at a faster speed by bevel gearing 51 and the belt pulley 47. The saw shaft and the two feed-motion shafts are driven by belting with fast and loose pulleys from an overhead shaft not shown. The connection between the worm gear 41, bevel gear 51, and shaft 44 is made by a clutch 43 movable by the lever 53 and rod 58, the latter having rack teeth at 63 where it is engaged by a pinion 62 operated by the hand-lever 59. Diamond holders or cutters 69, which may project and may be bevelled on their front edges, are held in slots in the blade 6, the surplus space being filled with a piece of steel or with solder, or with both, as at 68, Figs. 8 and 9. Saws 6 are secured on shafts supported at both ends by the divided clamps 71, held together by bolts 72 and in place by the set-screw 73, Fig. 10. The Provisional Specification states that thicker blades than usual are employed to permit of the use of larger diamonds, and the blades are made by turning down and grinding thicker sheets than usual. Steadiers for several saw blades on a shaft consist of forks adjustable on a carrier supported from the shaft pedestals or otherwise, and the carriers may also support the guards. Side projections may be provided on the saws to produce a cleaner cut. Band saws may be used. Spiegel containing 10 to 20 per eent. of manganese may be used in place of boart or diamond.

Title: Improved Means or Process for Treating Yeast.
Inventor: LAER HENRI VAN
Filed: 1899-01-31
Granted: 1900-01-06
Abstract: 2228. Laer, H. van. Jan. 31. Glucose and like carbohydrates.-Relates to a treatment of pressed yeast in order to obtain from it a ferment for the inversion of sugar solutions, glucose solutions, and other substances. The pressed yeast is liquefied by mixing it with one of a number of powdered substances such as iron, citric or oxalic acids, aldehydes, dextrose, glucose, alkaline chlorides or phosphates, ammoniacal and ferrous sulphates, alum, salt, &c. The liquefied yeast is allowed to ferment spontaneously, and the pasty mass is mixed with water and treated in a centrifugal drying-machine ; the liquid separated from the solid matters is distilled to obtain alcohol, while the residue in the still is filtered to separate the coagulated albumen, which may be dried or be converted into soluble protein matters, while the liquid resulting from the filtration is concentrated to serve as a food preparation. The solids resulting from the treatment in the centrifugal machine are used for inverting sugar solutions, and, when the inversion is completed, the solution is filtered or otherwise treated to separate from it a residue which is digested in water and again filtered, and the resulting liquid is added to the liquid obtained by filtering the residue left in the still before the latter liquid is concentrated to form a food extract. The solids resulting from the last mentioned filtration may be converted into a glucose solution by treatment with an acid.
Patent GB-189904801-A (GB)
Title: Improvements in and connected with Resistance Switches for Electric Circuits.
Inventor: HOLMES JOHN HENRY
Filed: 1899-03-04
Granted: 1900-03-03
Abstract: 4801. Holmes, J. H., and Broadbent, F. March 4. Switches for motors or for circuits where it is undesirable to switch on the whole current suddenly. The switch is so arranged that the resistances are cut-out slowly and automatically after the main circuit is completed, and means are provided for preventing the switch from being left in improper positions. Fig. 1 shows one construction. The moving part of the switch consists of an arm E, having contacts e<3>, e<4> for closing the main circuits at f and f<1>, and an arm A carrying contacts for connecting the contact - segment b<12> with the contacts b<1>-b<10> of the resistance switch. When the arm E is moved in the direction of the arrow by a suitable handle H, it drags the arm A by means of the hook e engaging a pin a<7>, and inserts the resistances in the circuit. When the main circuit is completed at f, f<1>, a stop e' releases the hook e, and the arm A is moved back over the contacts to cut out the resistances by means of the springs a and dash-pot C*. The arm E is held in the "on" position against the action of a spring by an electromagnet F. The circuit is broken by short-circuiting the magnet by a push i, or mechanically by moving the handle. In the modified form shown in Fig. 6, the handle H<1> projects through a slot in the casing, and the circuit can only be opened by short-circuiting the magnet as the handle passes under a cover d<1>. The handle is telescopic, and on pressing down the push i<1> it is shortened and remains entirely within the casing whilst passing to the " off " position, a stud h<3> passing along a guide d<2>. Fig. 7 shows another modification, in which the arm A is held by a stop k with the resistances cut-out. On breaking the main circuit, the stop is moved down, allowing the arm A to pass on to an insulated stop b, and the circuit cannot be again made until the arm E is moved back and the catch e brought into engagement with the arm A. In another modification, a second electromagnet is employed to hold the arm A on the contact b<1> until the circuit is broken. In yet another form, the handle H<1> is connected to the arm A instead of E, and is moved back by the former. Instead of having wire resistances, liquid resistances may be employed and the contacts may be arranged in straight lines instead of being circularly disposed.
