Title: Process for the Production of Benzoic Acid from Coal Tar Oil.
Filed: 1899-04-14
Granted: 1899-07-08
Abstract: 7867. Aktiengesellschaft f³r Theerund Erd÷l-Industrie and Kraemer, G. April 14. Benzoic acid. - Relates to the production of benzoic acid in a high degree of purity from coaltar oils. A fraction of coal-tar oil boiling between about 160‹ and 240‹ C., obtained by fractionating the light and middle oils, is first treated with dilute soda lye, in the cold, for the removal of phenol and cresol. The residue is mixed with an alkali, such as caustic soda of 1À4 specific gravity, for decomposing the benzonitrile present, and the mixture is heated externally and with live steam, in a vessel fitted with a stirrer and a condenser, as long as ammonia is given off in considerable quantity. The remaining oils are removed, the alkaline solution is neutralized with carbonic acid or a mineral acid, and any phenol or resinous or oily matters thereby liberated are skimmed off. The remaining solution is acidified while hot, and upon cooling benzoic acid crystallizes out in white crystals.

Inventor: JOHNSON JAMES YATE
Filed: 1899-11-20
Granted: 1900-11-20
Abstract: 23,123. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Nov. 20. Formyl-, benzoyl-, and ethoxycarbonyl-phenylglycocoll-o-carboxylic esters are produced by heating phenylglycocoll-o-carboxylic dimethyl or diethyl ester with formic acid in a closed vessel, or with benzoylchloride or chloroformic ethyl ester on a water bath. The formyl and benzoyl derivatives are extracted from the mixture by ether. The ethoxycarbonyl derivative remains in an almost pure condition after washing the melt with dilute sodium-carbonate solution. It boils without decomposition above 360‹ C. Dyes, artificial.-The foregoing new acyl compounds are converted into indoxyl by boiling them with caustic alkali of about 20 per cent. strength with exclusion of air, or with caustic potash, milk of lime, or baryta water ; or by allowing them to stand with these reagents. The condensation is effected by metallic sodium, sodium alcoholate, ammonia, or hot sodium-carbonate solution. If fuming sulphuric acid containing 4 per cent. or more of sulphuric anhydride is used, the condensation is accompanied by oxidation and sulphonation, indigo sulphonic acid being formed. This is precipitated by addition of salt to a solution of the melt in water.

Granted: 1900-04-21
Abstract: 23,159. Heys, W. E., [LÚpicier, L.]. Nov. 21. Parallel knitting. - ma - chines. - Relates to methods of fashioning in which only one loop is transferred on each needle bed at one time, no matter how far in from the selvage the fashioning takes place. At each end of each needle bed A, A' is a supplementary needle bed B', B<111> with tricks for, say, five needles 1, 2, 3, 4, 5. The bed B<111> is carried on a sleeve on a shaft o, about which it can be rocked ; it rests on a bar 18 capable of sliding on a fixed bar 20, and has a notched guide 7, with which engages a pivoted pawl 14 to prevent end motion; it is held down by a turned-up lug 21, on the bar 18, which is pulled into a notch by a spring 23. When the pawl 14 is disengaged, the bed B<1> can be shogged inwards or outwards on the shaft O. By means of the rod 40 the bar 18 can be pushed to the left ; the inclines 22 then raise the bed, and cause it to rock on the shaft O at the same time the rod 40 acts on a slotted pivoted lever 36 against the action of a spring 38, and so raises a sliding bar 41, which at its upper end is bent downwards and inwards at q, Fig. 3<a>. When the bed B' is raised, the part q clears the loops out of the needle tricks, and allows the auxiliary bed to be shogged. The needles for the auxiliary beds are shown in Fig. 10 ; when the bed is down, the upper parts of the needles are in the same plane as the main needles. To make a narrowing, the needles 25 on the front and back main beds are raised so that the loops lie on the latches ; the slotted bodkins or coverer points, Fig. 9, now come down on the needles 25, Fig. 11, and then draw the needles up as in Fig. 12, and then descend and open the latches, leaving the loops on the bodkins. The bodkins now shog and transfer the loops to the next inner needles 26. The needles 25 now go out of action. The auxiliary beds are now raised, the loops on them are cleared from the needle tricks, and the beds are shogged inwards, the needles 5 taking the places of the needles 25. The fashioning-arrangements at each end are independent.

Title: Improvements in Speed Changing and Reversing Gears for Motor-driven Vehicles and other purposes.
Inventor: BROWN HARVEY EZRA
Filed: 1900-08-22
Granted: 1901-07-06
Abstract: 15,036. Brown, H. E. Aug. 22. Motor road vehicles.-Relates to speed changing and reversing gearing for motor-driven vehicles and other purposes. The driven shaft b drives a worm-wheel c, which is loose on the shaft A to be driven and carries one or more planet-wheels f. These are mounted loosely on studs e, and engage on the one hand with a pinion g fast on the shaft h and on the other with an internal wheel k, which may be held stationary or have its motion controlled by a suitable brake or governor, or be driven so as to regulate the speed and direction of rotation of the shaft h. In the arrangement shown in Fig. 1, the wheel k is connected by worm gearing with a shaft carrying a friction-wheel t, which may be slid along its shaft so as to engage with a friction disc r at a greater or less distance from the centre thereof, the disc r being driven by bevel gearing from the main shaft b. When the wheel t engages with the centre of the disc r, the wheel k is stationary, and, as the wheel t moves towards the periphery of the disc r in one direction, the wheel k is allowed to follow the wormwheel c and the rotation of the shaft h is gradually reduced until it is brought to rest. If the wheel k be now driven at a greater speed than, and in the same direction as, the wheel c, owing to the continued movement of the wheel t, towards the periphery of the disc r, the direction of rotation of the shaft h will be reversed. When the wheel t reaches the periphery of the disc r, the shafts and g are preferably connected together by toothed gearing, clutch teeth y on the wheel t automatically engaging with corresponding teeth on a bevelwheel x, which is loose on the shaft s and engages with a similar bevel-wheel on the shaft of the disc r. The mechanism may be enclosed in a casing, and, when no reverse driving is required, an oil pump may be used for controlling the motion of the shaft s; in this case the pump may circulate the oil through the casing for lubricating purposes.

Patent GB-190212603-A (GB)
Title: Improved Process and Machine for Shrinking Woven Fabrics.
Inventor: BEHNISCH CARL HERMANN
Filed: 1902-06-03
Granted: 1902-10-02
Abstract: 12,603. Behnisch, C. R. June 3. Compound processes; winding; unwinding.-Fabrics are shrunk by a dry or wet process by means of apparatus such as that shown in Figs. 2 and 4. Two layers of fabric, having their front faces in contact, are wound on the shrinking-cylinder 1, which, while the fabric is being wound, is carried on weighted arms 5 pivoted at 6 to the frame of the apparatus. To facilitate winding, the separate layers of fabric are wound on feed-rollers 10, 11, which consist of sleeves adjustable on the roller spindles, so that the feedrollers may be readily moved so as to bring the fabric into line with the shrinking-cylinder. A slight tension is put on the rollers 10, 11 by means of friction discs, and the light winding of the fabric on the roller 1 is ensured by a contact-roller 26 on which the roller 1 rests. The rollers 10, 11 receive longitudinal movements in both directions to ensure that the thickened selvages of the fabric will not be superposed. On the cylinder 1, which is perforated and closed at one end, is wound, in the first instance, a length of porous cotton fabric, on which the fabric to be shrunk is then wound, the latter being finally covered with a similar layer of cotton fabric, which is sewn in position, The arms 5 are then lifted, and the roller 1 is seized by the chains 57, 58 of a crane and deposited on bearings in a boiler 53. A box, having openings leading to an exhaust blower 70 and to a pump consisting of toothed rollers 75, 76, has a passage 65 leading to the open end of the roller 1 when in position in the boiler, a sleeve 62 which screws on to the end 3 of the roller serving to make a steam-tight joint. A steam pipe 6,7, provided with a suitable valve, is located within the passage or pipe 65 to convey steam to the interior of the roller. When the shrinking is effected by the dry process, steam is first passed into the interior of the roller 1, through which it escapes to the fabric, and finally to the boiler. Or steam may be admitted to the exterior of the fabric by means of a perforated pipe 69, the seam being then withdrawn through the fabric by means of the blower 70. When the wet process of shrinking is adopted, water pumped from a reservoir is admitted with steam as before in the case of steam alone. While the fabric is thus being operated upon, the roller 1 is rotated. The roller is finally lifted from the boiler and placed on the arms 84, and the fabric is unwound by rollers 89, 90, and at the same time folded by an arm 97.

Title: Improvements in and connected with Apparatus for Controlling the Traffic on Single Line Railways
Inventor: SMITH EDWARD WYTHE
Filed: 1902-06-24
Granted: 1903-06-18
Abstract: 14,269. Smith, E. W. June 24. Controlling traffic on railways, staff systems for.-Relates to staff systems of the kind described in Specifications No. 1263, A.D. 1889, and No. 8998, A.D. 1900. The apparatus for receiving the staff at the stations is fitted with a counter to record the number of times a staff has been inserted or removed, a paper band for recording the purpose for which the instrument has been operated, and an indicator for showing the condition of the section. On the end of the usual drum for holding the staffs is a disc D, Fig. 1, with two rows of pins p, p and four segments of a ring r. The disc D is turned through 90‹ in one direction when a staff is inserted, and through 90‹ in the opposite direction when a staff is removed. These rotations of the discs raise or depress the lever L by the action of the segments r on the projection l. The starwheel X, supported on the lever L, engages with the outer or inner row of pins p, according to the direction in which the disc D is turned, and a counter connected to the star-wheel records the number of times a staff is inserted or removed. The lever L, when freed from the segment r, is returned to its normal position by the counterweight lever B, T. Reels carrying a band of paper are driven by bevel gearing with or without a reversing-clutch from the axis k. The record is written on the paper band through an opening in the casing. The indicator for showing the condition of the section is mounted on the top of the staff apparatus, as shown in Fig. 7. A permanent magnet and an electromagnet are mounted at right-angles. An armature consisting of two arcs 3, 4 of soft iron mounted on brass arms rotates on an axis 1. On the axis of the armature are fixed the small semaphore arm 5 and the two " flags " 6, 7 labelled " train on line (arriving) " and " train "arrived." When a current is sent through the electromagnet in one direction, the semaphore arm is raised and the flag 6 is brought opposite the opening as shown in Fig. 7. When the current in the electromagnet is reversed, the arm is lowered, the flag 7 is brought opposite the opening. A flag 8 labelled " train on line (going) " is mounted on an axis 9, and is brought opposite the opening by the movement of the lever L when a staff is removed. When a line is divided into two sections, the staff apparatus used is that shown in Fig. 10. Staffs are placed in three drawers 1, 2, and 3. Two of these drawers 1, 3 contain staffs for the sections, and the middle drawer 2 contains a staff for the whole line. When the drawers 1, 3 are pulled out. so that the section staffs can be removed, the drawer 2 is locked by the bell cranks T and vice versÔ. A drawer cannot be pushed in till the levers L are raised by inserting a staff ; otherwise the notch J arrests the drawer. In a modification, the opening of the drawer is determined by an electrically-controlled lock.
