Patent GB-190922218-A (GB)
Title: Improvements in or relating to the Treatment of Lac.
Inventor: FREYMUTH WILLIAM ADOLF
IPC: C09F1/00
Filed: 1909-09-29
Granted: 1910-09-29
Abstract: 22,218. Freymuth, W. A. Sept. 29. Resins. - In a process for obtaining sud - lac or shellac, sticklac is crushed to a pulp with water. After a short soaking, the pulp is circulated from a lower tank to an upper, or through an agitating-tank, by a centrifugal pump, preferably several times and with fresh waters. The scouring may, be assisted by adding sand d & c. o r chemicals. The pulp is then introduced into a spitzkasten 1, Fig. 1, through a central funnel 3 o r otherwise. Pressure water is admitted through a central pipe 6 near the bottom of the spitzkasten 1, and carries upwards and into a circumferential trough 2 the light particles of coccus bodies &c. and semi-soluhle albuminous matter. Sand &c. is intermittently discharged through a cock 7 at the bottom, cleaned sud-lac through a larger valve 8 higher up, and lighter lac particles and coccus bodies through a still higher cock 9, whence they pass to a second spitzkasten 10 for separation. The sud-lac is next strained and dried, when, with or without vanning, it is ready for sale or further refining to button-lac or shellac. For the latter purpose, the sud-lac is placed in the basket 14 of a centrifugal filter, Fig. 2, which is maintained at from 120-140‹ C. by the circulation of hot air through conduits 17, 18. The melted and filtered resin and wax passes through to the casing 16, whence it runs off through a conduit 19 and is agitated until it has cooled gradually to 80‹ C., when it has formed a homogeneous mass. If a solid basket is used, the purified lac is forced over its edge while the refuse remains packed against the walls. The agitator, preferably cylindrical, is heated or unheated, or is heated in one part only, so that the lac being fed in at the hot end has reached the right temperature at the exit. Part of the conveyer in the cylinder may be artificially cooled. The agitator may be used for mixing additional matter with the lac.

Title: Process and Apparatus for Spinning or Twisting Strips or Small Bands.
Inventor: KRON RUDOLF
IPC: D02G3/08
Filed: 1910-02-24
Granted: 1910-10-13
Abstract: 4675. Kron, R. Feb. 24. Paper &c., forming threads from.-An apparatus for twisting strips or small bands of paper, asbestos, &c. comprises a disk-shaped carrier b, Fig. 1, containing a roll, bobbin, or ball a of the material, and adapted to be rotated at a high speed in a shallow casing d by a spindle b<1> carried on an axle c fixed in the casing. The casing is closed by a hinged cover e from the inside of which projects a hollow truncated cone f, which directs the strip radially and axially towards the centre as it is drawn off from the centre of the roll &c. The twisting takes place in the hollow g so that no ballooning can occur outside the casing. The strip, as it is drawn off, is subjected to a braking action due to the centrifugal force developed by the rotation of the roll, and, as the air in the casing is also rotating, no resistance is encountered. Fig. 2 shows a compact arrangement in which a number of the casings are arranged with inclined spindles in rows in such a manner that the casings overlap and each serves to support the spindle of the next carrier. In the arrangement shown in Fig. 3, a number of casings are arranged in two transverse rows, the casings in one row coming opposite the spaces between the casing in the other row. The strips or bands to be twisted are taken in the shape of flat rolls from one or more bobbins or rolls i placed on a table k. The spun or twisted material is led from the casings d around rods l, m and a cylinder n in the top of the frame o to a spindle p, on which it is wound up. When the spindle is full, it automatically moves down the inclined surface q into the frame r. The spindle wharls are rotated by cords led around a drum s and oblique guide-rollers t.

Granted: 1911-12-07
Abstract: 28,503. Sturdevant, H. C., Ingham, J., Sturdevant, W., and Goodwill, F. Dec. 7. Thread guides.-Relates to traverse mechanism for the roving or thread guides of spinning and like machines. The thread-guides 9 are carried by the traverse bar 8, to which a short rail 10 is adjustably secured, and on which is mounted a box casting 14 having an opening 15, and a bent arm 16 carrying a stud 18 engaging the groove in a cam 6 on a shaft 5 driven by a worm and worm-wheel from the back roller shaft 2. A shaft 19, journaled in the box 14 and a bracket 23 on the bar 8, carries a grooved cam 20 disposed in the opening 15 and engaging with a stud 13 on the rail 10. The shaft 19 is driven by, and is free to slide longitudinally within, a pinion 22 driven by a worm 7 on the shaft 5 and retained against lateral movement by any suitable means. The box 14 and consequently the bar 8 are reciprocated from the cam 6, but, since the shaft 19 has a slow rotary movement, the relation of the box 14 to the traverse bar 8 is constantly changing, and consequently the terminal points of the traverse are constantly changing, so obviating grooving of the drawing - rollers by the thread.

Abstract: 26,420. Dental Manufacturing Co., and Sonnex, R. W. July 6. Dental seats; seat adjustments.-The back of a dental chair is adjustable by means of a clutch which can be used as a friction or positive grip as desired. Fig. 1 shows a chair in which the back 9 is carried by a support 11 pivoted to a bracket 13 and angularly adjustable by a rod 10 passing through a clutch 12 shown in detail in Figs. 2 and 3. The friction grip consists of a wedge 20 which may be released by depressing the end 24 of a spring-pressed lever 18 pivoted at 26 and engaging a pin 19 projecting from the wedge 20. The positive clutch mechanism consists of a spring-pressed pin 23 adapted to engage holes 14 on the bar 10. The head of the pin 23 is embraced by a camshaped fork 22 forming a part of the lever 18. When the handle 24 is depressed, the pin 23 is disengaged from the bar 10. The pin 23 may be held permanently out of engagement with the bar 10, so that the wedge 20 alone is operative, by withdrawing and then rotating the pin 23, projecting pins 25 on the pin 23 engaging in recesses (not shown) in the sleeve 27.

Abstract: 294. Mossop, J. A. Jan. 4. Bottles, washing. - In bottle-washing machines of the kind in which the bottle is gripped and revolved by driving and bearing rollers while in contact with stationary internal and external brushes, the bearer rollers and preferably also the external brushes are mounted so that, by actuating a single member or part of the machine, they may be all brought simultaneously into their acting and non - acting positions. The bottle is placed over the fixed internal brush f<2> with its neck in contact with a rotary head c<3>, which, together with the brush, is carried by a bracket d adjustable in the slotted end wall of the tank. The pivoted end brush t is then raised from an horizontal position against the action of the spring w into the vertical bottle-contacting position, as shown. This movement raises a pivoted frame o carrying the three external brushes s and the two pairs of bearing- rollers i into the acting position. The frame o is connected adjustably to the end brush at x and to a pair of vertical rods at r<3>. These vertical rods are adjustably mounted in a member m which is secured to the wall of the tank and also forms a bearing for the shaft of the fixed driving-roller g. The external brushes are mounted on transverse members of the frame o and are arranged as shown in Fig. 3. Two pairs of bearing-rollers i form with the driving-roller a three-point-support for the bottles. Each pair of rollers is resiliently mounted on a block j, carried by a trough-shaped transverse member l of the frame o. When the bottle has been rotated by the driving-roller for a sufficient length of time, the end brush is moved back again to its horizontal position, thus withdrawing the bearing- rollers and external brushes and facilitating the removal of the bottle. To suit bottles of varying length, the brush t may be pivoted in any one of the slots u<2>.

Oil from the tank flows by gravity through a pipe 50 into a duct in the crank-shaft communicating with a groove 51 in the cap 42 of the revolving casing 1 carrying the cylinders 5. The oil passes by a pipe 52 to an annular reservoir 41, from which, when the engine is working, it is forced centrifugally past spring-pressed ball valves 47 in pipes 45 and through needle regulating-valves 49 to orifices in the cylinder walls to lnbricate the pistons 6. A passage 53 in the crank-shaft conveys oil to a passage 54 in the crank-pin, from which ducts 56, 57, 58, 59 lead to the bearings, gudgeon-pins 14<1> and to the cam 18 that operates the fuel-inlet valve 15.
