Title: Improvements in or relating to safety devices for lifts
IPC: B66B13/18
Filed: 1938-12-19
Abstract: 522,823. Operating well gates of lifts. BROOKS, F., LOWE, H., BARON, J., and RAMSDEN, C. C. Dec. 19, 1938, No. 36868. [Class 78 (iii)] [Also in Group XXV] Single and double swinging well gates are interlobked with the motor circuit so that the lift cannot be started ordinarily or by tampering until all gates are closed, and in addition the gates are positively locked in closed position. Figs. 1 and 4 show the invention applied to double overlapping swing doors 1, 2. The door 2 which closes last, carries a sliding bolt 3 having a slotted member 10 at its lower end co-operating with a crank 7 on the shaft 5. By raising the hand lever 8, from the position shown, in which it engages a member 12 on the other door, to the upper of the limiting positions defined by the studs 30, the crank is operated to pull the bolt 3 downwards out of the fixed casing 14 and at the same time releases the stud 16 to break the motor circuit or operate a mechanical locking device to prevent starting. To prevent the levers 8 being operated when door 2 only is closed, and to prevent starting of the lift by insertion of an instrument into the casing 14, a pair of perforated bars 19, 20 sliding through the casing 14 are linked to vertical pivots 25 on the doors so that the opening and closing movements of the doors cause them to slide relatively to one another. Only when both doors are closed do the perforations register to allow the bolt 3 to pass to the stud 16. The linkage is adjustable in length by screwmechanism to allow fitting to doors of various widths. For a single door only one member 20 would be employed.

Patent GB-995764-A (GB)
Title: Process for the separation of aqueous suspensions of carbon black
IPC: C09C1/48
Filed: 1961-10-19
Abstract: Carbon-black is removed from an aqueous suspension thereof by mixing said suspension with a water-immiscible auxiliary liquid to form an aqueous phase and a mixture of carbon black and auxiliary liquid, passing at least the aqueous phase through a collecting vessel through which are also passed agglomerates of carbon black and the water-immiscible liquid such as to build up a layer of agglomerates which is at least partly flowed through by the aqueous phase, and removing from said vessel agglomerates, substantially separated from the aqueous phase, at approximately the same level as the discharge from the vessel of the aqueous phase. It is preferred that the aqueous phase and the agglomerates be continuously passed through the collecting vessel and that the liquid level in said vessel be kept constant.  Agglomerates of carbon-black and a hydrocarbon or hydrocarbon fraction boiling at 190 DEG  to 340 DEG  C. are very suitable and it is preferred to employ agglomerates prepared from the original carbon black suspension. The collecting vessel may be a vertical vessel having the bottom, or parts thereof, or part of the side wall permeable to water but not to the agglomerates and this permeable section may consist, for example, of porous or perforated material.  If the side wall is permeable the vertical extent of the permeable section should be such that water leaving the vessel passes through at least part of the agglomerate layer and said agglomerates may be removed by employing a riser which opens into the vessel at about the level of the permeable section.  If the bottom is permeable it should preferably be flat and slope towards the agglomerate discharge line at an angle of not more than 15 degrees and it may be of advantage to shake the vessel or the bottom or part thereof. The vessel may also be provided with one or more collecting compartments, connected to the vertical vessel via the permeable sections, and a conveyer belt, permeable to water but not to agglomerates, connected to the agglomerate discharge line.  Three apparatuses for performing the process of the invention are described.  Reference has been directed by the Comptroller to Specifications 834,940, 834,989 and 846,219.

[Also in Group XXIII] A method and apparatus for cutting grooves in curvilinearly profiled passes of a grooved roll intended for making relief-patterned bars comprises a tool which is periodically moved over the range of the roll pass about an axis tangential to the centre of the pass, the roll being rotated to obtain a relative feed movement of the tool. The work 1, Figs. 1 and 2, is rotated to effect the cutting of a sinusoidal groove in the roll pass 2. A tool 4 is mounted for rotation about its longitudinal axis in a holder 5 and the non-cutting end of the tool is connected to a crank 9. The holder 5 is carried in a yoke 11 which can swing about the axis 6 (perpendicular to the paper in Fig. 1).
