Title: Improvements relating to the Washing of Paper-making Materials and to the Recovery of Soap and Alkali from the Water used therein.
Inventor: KNOPF ANNA BARBARA
Filed: 1900-07-23
Granted: 1901-07-13
Abstract: 13,255. Knopf [nÚe Fuchshuber], A. B. July 23. Raw materials, treating; waste products, treatment and utilization of ; cleaning rags and fibres.- Relates to the washing of paper-making materials and the recovery of the fatty matters and alkali from the waste water. Waste paper, ropes, &c. are agitated for ten minutes or longer in water containing soap, and dried by centrifugal action. The soap is separated from the waste water by means of salt, and treated with caustic lime or the like, the colouring-matters being mixed with the insoluble soap, and the lye which remains being concentrated, if desired, and used again for soapmaking. The insoluble soap is then treated with sulphuric cr other dilute mineral acid, and the fatty acid separated from the acid water is purified by distilling in a vacuum or by superheated steam, and may also be used again in the manufacture of soap. The printing-ink and other foreign matters which were suspended in the fatty acid remain as deposits in the distilling vessel or retort, and may be mixed with resin oil &c. for re-use. The washing-water may be treated directly with caustic lime, or with a dilute mineral acid, if desired.
Patent GB-190014641-A (GB)
Title: Improvements in Machines for Making Corkscrews.
Inventor: CLOUGH WILLIAM ROCKWELL
Filed: 1900-08-15
Granted: 1901-01-19
Abstract: 14,641. Clough, W. R. March 5, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Bending; wire.-Relates to machines for making corkscrews from wire. The wire 31, Fig. 1, is drawn from a reel through any usual straightening- device 32 by the feedmechanism 35, which advances it for attachment to a handle inserted by hand in the revoluble socket 76. The socket is rotated to twist the wire round the handle, and the necessary length of wire for forming the screw is cut off by the cutter 56. The crossed ends of the wire attached to the handle are then twisted by the chuck 92, 93, to form the stem 122 and spiral 123 of the corkscrew, which is shown completed in Fig. 14. The feedmechanism, Figs. 1 and 8, comprises a carriage 35, mounted to slide on the guide-rail 37, a clutch 36 on the rock-shaft 40 for gripping the wire 31, and a slotted lever 46, which actuates the rock-shaft 40 by engaging the arm 41 thereon, and is actuated by an eccentric 51 to move the carriage 35. An adjustable connection between the eccentric 51 and the lever 46 enables the feed to be regulated. The cutter 56, Figs. 1 and 9, is adapted to sever the wire at the end of the guide 59, and is operated for this purpose by the cam-wheel 70 engaging the head of the adjustable nut 65 on the cutter. The return of the cutter is effected by the same cam engaging the lever 69. During the feed-move ment, the free end of the wire passes between the stud 77, Fig. 6, on the socket 76 and the handle inserted therein. The rotation of the socket, for twisting the wire around the handle, is effected through the gearing 78, 79, 83 by the sliding racks 82, actuated by the cams 88, the wire being gripped during this movement by the pivoted toe 90 and by the cam-actuated lever 91. After the wire has been cut, its crossed ends are received into notches 97 in the sleeve 93, mounted on the chuck 92, the chuck and sleeve being advanced by a cam-actuated lever 118, Fig. 1. The chuck and sleeve are rotated by gearing 99, 101, &c. During the twisting of the wire by the sleeve, the latter is pushed back on the chuck, to permit the wire to be bent to spiral form on the helical mandrel 103. The mandrel is clamped to the chuck, during the operative rotation of the latter, by the bolt 108 engaging in a cam-groove on the chuck, the bolt being mounted in the tailstock 104 fixed on the mandrel. Near the end of the operation, the latch 114, previously depressed by the rod 115, is allowed to rise and disengage the bolt 108, after which the chuck, mandrel, and sleeve are returned to the starting position by the springs 120, 121, to disengage the mandrel from the finished corkscrew. The machine is automatically stopped at the end of each operation, and is restarted by the attendant after he has removed the finished corkscrew and inserted a fresh handle in the socket 76. When it is not desired to attach the corkscrew to a handle in the machine, the corkscrew may be formed on a dummy handle.

Title: Improvements in Alarm Attachments for the Locks of Doors, Windows, and the like.
Inventor: SCHIMANDI GEZA
Filed: 1901-05-02
Granted: 1902-04-17
Abstract: 9131. Schimandl, G. May 2. Alarms, burglar and like.-Relates to alarm locks for doors, windows, safes, strong-rooms, &c., a surreptitious attempt to open or force the lock releasing a trigger, which fires a cartridge &c., and also completes the circuit of an alarm located at some suitable distant place. The trigger c, Fig. 1, is normally held up by the catch o<1> on the spring-controlled arm or lever o, and, when released from the catch, is actuated by the spring d and lever f to fire the cartridge &c. h, and to close the alarm circuit i at the contact i<1>. The trigger is reset by the arm w<1> by means of a key inserted in the socket w, or the arm may be on the key. In a modification, the trigger c is directly connected to the spring d, and is formed with a socket for the setting-key. The lock bolt l is operated in the usual way by a key, the barrel of which must fit on the conical pin n and pass inside the bosses or projections r, the pin and projections being carried by a disc m arranged in contact with or forming part of the arm o. If it is attempted to open the lock with a key which does not fit correctly, the disc m and arm o are pressed back by the key, so that the trigger is disengaged from the catch o', and actuates the alarms. To give the alarm when a key not having the proper bits is employed, the disc is formed with projections s, Fig. 5, which are clear of the correct key, but are adapted to be engaged by a wrong key to effect the displacement of the disc m and the release of the catch o'. Fig. 5 shows two other arrangements for releasing the catch. The spring- controlled bolt t is attached to cords, threads, &c., arranged in the room, chest, or other receptacle to be protected, e.g., over the inside of a door. When the cords &c. are broken, by an attempt to force the door &c., the bolt t is released and strikes the projection o<2> on the arm o, so releasing the catch. Anotter projection o<3> on the arm o is adapted to release the catch on an attempt to shoot or force the lock bolt l. The Provisional Specification also states that the trigger may be released from the holding-arm by the vibration of the latter, on an attempted opening of a door or window, and that the trigger may explode a glass ball instead of, or in addition to, a cartridge or cap.

Slotted bars 6, pivoted at 7 to the top 1, engage headed pins 9 on the legs. When the legs are in use, springs 11 press the pins 9 into notches or recesses 10 at the end of the slots 8, and so keep the legs in position till they are released by a pressure in the direction of the arrow 12, Fig. 1. When the legs are folded, pins 14 spring into the slots 8.
