Title: Improvements in doctors for paper-making and like machines
IPC: D21G3/00
Filed: 1935-01-16
Abstract: 452,147. Doctors. JOHNSON, L. S., and VICKERY, F. W., 4, Lambeth Palace Road, London. Jan. 16, 1935, No. 1499. [Class 96] A doctor comprises a flexible blade 1 and a holder receiving but not clamping the rear part of said blade, the holder including retaining means releasable from the end of the holder, engaging the blade positively at intervals along its length to prevent its disengagement laterally from the holder. The rear edge of the blade 1 and its projections 2 are received in a slot formed by the two parts 3, 4, Fig. 1. The part 3 has a sliding connection with the part 4 and they are secured in the working position by a split pin 5. The front wall of the part 3 has notches 6 corresponding in size and relative spacing with the projection 2. In the working position, the slots 6 do not correspond with the projection 2. To release the blade the split pin 5 is removed and the part 3 slid to bring the slots 6 and projections 2 into correspondence. In a modification, the upper part of the holder has no slots but is formed on its under side with inclined surfaces which ride on pins set in the lower part. In the working position the parts are pushed together by leaf springs. By removing the split pin and sliding the upper part it may be lifted to permit lateral removal of the blade. The blade may be received in a one-piece holder with slots corresponding to the projections and a sliding member in the holder to cover the slots in working position. Fig. 10 shows as a further modification a holder 20 receiving a round rod 17 across which notches 18 extend half way. The front wall of holder 20 is notched at 21 opposite the projections 2, and the notches are normally blocked by the rod 17. The blade is freed by turning the rod 17 through a right angle. In Fig. 11 a round rod 19 or if desired a tube, has a groove to receive the projection 2 and is normally secured against rotation by the split pin 5. The blade instead of having projections 2 may have perforations near its rear edge and retaining pins carried either on a rotatable rod or supported on cam surfaces on a slidable rod pass through the perforations to hold the blade during working. Specification 360,028 is referred to.

Abstract: 176,945. Rolin, H. Jan. 11, 1921. Rolling-machines.-Apparatus for rolling dough to form loaves &c. comprises two rollers 1, 2, which deliver the dough on to a band 3 of fabric or other material secured at one end to a rod 4 and at the other end to a spring 23 located beneath a table 5 over which the band passes. The rod is detachably connected, by a spring catch 17, to two levers 14 pivoted at their lower ends to the framework, and the rod is guided for movement up to the forward end of the table by guides 6 and slotted bars 8. Above the table 5 is a table 9 having extensions 12, and resiliently attached to the levers 14 is a roller 11 which, when the levers are swung, passes beneath, and in contact with, the table 9 and the extensions 12. The levers are moved by the engagement therewith of pins 16, 16<1> on rotating discs 15, cranked parts 28, 29 being provided on the levers for the passage of the pins; this mechanism gives a quick return and a dwell at the starting position. In operation, the dough is delivered on to the band in an even laver. The levers 14 move from the full-line position and carry the rod 4 up to its limiting position 4', where the catch is opened by a trip 18. The rod then stops, the dough lying in the pocket 3<1> formed in the band. The levers, continuing their movement, cause the roller 11 to engage the band, thus moving the pocket between the tables 5, 9, where the dough is compressed and rolled. The levers move to the position shown in dotted lines, where the rolled dough is delivered, and then move back, the rod 4 becoming re-engaged during the backward movement. The table 5 is adjustable vertically by a screw 10; the apparatus may be driven by a handle 24 or continuously by a crank 25. The band is sprinkled with flour from a receptacle 9 by a brush 20, and scrapers 21, 22 are provided to remove dough from the rollers 1, 2.

Title: Improvements in or relating to apparatus for preventing theft from closed compartments
IPC: B61D19/00
Filed: 1921-01-12
Abstract: 178,202. Vining, L. E., and Goodman, W. R. Jan. 12,1921. Theft and like alarms.-Relates to apparatus for preventing theft from closed compartments, such as railway wagons, and consists of two arms 11 carrying at their ends discs 12 which can be brought opposite to apertures 13. When the discs 12 are opposite the apertures 13 they are in the " All right " positions, but if swung away from the apertures they are in the " Alarm " positions. An horizontally-disposed rod 10 mounted in bearings carries at each end the arm 11 and disc 12 and is loaded by means of spiral springs 15 which normally tend to turn it into the " Alarm " position. An enlargement 16 having one or more holes is provided on the rod 10. Above the rod 10 there is mounted a guide 17, wherein slides a weighted member 18 which has a pin 19 formed on its lower end, this pin being adapted to engage with the holes in the enlargement 16. The weighted member 18 is provided with a pin 20 which extends through a slot 21 in the casing 17. Two flexible lines 22, 23 are connected to the weight 18 and are led through tubular guides 24, 25 along the back and sides of the compartment to the doors on each side. The flexible lines extend as far as the ends of their respective guides and are connected through loops 30 and lines 33 to weighted locking-bars, of which one, 36, is shown pivoted at 37 on the doors 29. This bar is so disposed that when in this position it engages the second part of the door 28 to provide a lock inside the compartment. A movable cover-plate 32 for a trip setting opening 31 has provided on its inner surface a tongue-like member 34 which carries an upwardly-directed hook 35. The hook 35 does not offer any obstruction to the entry of the line 33, but it acts as a barb to engage the line 33 should the coverplate 32 be raised. In operation the indicating- discs 12 are brought into the " All right " position, and the. weight 18 is allowed to fall, so that the pin 19 engages one of the holes in the part 16 so as to hold the rod 10 against any turning movement under the influence of the springs 15. A pull on the lines 22, 23 resulting from an attempted opening of the cover-plate 32 or door, raises the weight 18 and releases the indicator. Fig. 5 shows a modified construction, and, in operation, any pull on the lines lifts the pin 40 out from engagement with the hole 42 and allows the indicator to move into the " Alarm " position. The turning of the shaft 10 brings the hole 41 into alignment with the pin 40, and as soon as the tension of the lines is released the weight 18 falls and the pin 40 enters the hole 41 to its full depth so that the pin 20 travels down the slot 21 to the bottom. The indicator is therefore locked in the " Alarm " position and any attempt to release it, by pulling on the lines, merely lifts the pin 20 into the extension 43.

Filed: 1942-02-14
Abstract: <PICT:0571273/IV/1> An alkalimetal amalgam and water or an alcohol having less than 4 carbon atoms are passed in countercurrent through a space containing packing.  The space is flooded with the amalgam, and since the packing, which is made of material with which mercury does not amalgamate, is wetted by the water or alcohol, the latter passes against the current of amalgam in the form of a film.  In the Figure, a hollow cylinder 10 of iron or ceramic material filled with pieces of graphite receives water or alcohol at the bottom and amalgam from an annular chamber 12 at the top. Hydrogen escapes by tube 18 and alkali hydroxide or alcoholate solution by tube 17. Liberated mercury is removed from a collector cone 21 by tube 20. Alternatively, the mercury may be removed through holes in the lower part of the cylinder into an annular jacket.

Title: Process for separating aluminium hydroxide from silicic acid
IPC: C01F7/46
Filed: 1931-07-16
Abstract: Aluminium hydroxide is separated from a mixture thereof with silicic acid, obtained for instance by dissolving clays in sulphurous acid and precipitating the alumina, in the following manner:--The mixture is dissolved without drying, and preferably in a freshly precipitated state, in sulphurous acid, and the solution heated at gradually increasing temperature under conditions preventing escape of sulphur dioxide until silicic acid coagulates, the solution being left in contact with the precipitate preferably until cool, when the aluminium bisulphite remaining in solution is separated and alumina precipitated therefrom by expelling sulphur dioxide.  Alternatively the solution may be heated in a closed vessel the size of which is large compared with the space occupied by liquid, so that a limited escape of sulphur dioxide occurs during heating and reabsorption occurs during cooling.  In the heating step, incoming solution may be preheated by the hot liquid being discharged.  In an example a mixed precipitate is dissolved in just sufficient sulphurous acid and the solution heated gradually to 140-175 DEG  C., cooled to 80 DEG  C. and filtered from separated silica, whereafter alumina is precipitated.
