Title: Improvements in and relating to cylinder locks
IPC: E05B27/08
Filed: 1944-11-13
Abstract: 589,871. Locks. YALE & TOWNE MANUFACTURING CO. Nov. 13, 1944, No. 22371. Convention date, Nov. 12, 1943. [Class 44] Axially-moved tumblers 12, actuated by the insertion of a key 37, have deep slots 20 which, when aligned with a barrier 25, permit rotation of a plug 11 together with the key. The key is held in the lock by a pin 46 being forced into a hole 50, in the key, due to camming action of a groove 45 on the head 41 of the pin. When shallow slots 30 in the barrier, and one set of shallow slots 21 in the tumblers, are in alignment, the key plug may be rotated slightly (see Fig. 5), but it is then held by the barrier against further rotation. This renders the lock difficult to pick. The plug 11 and the barrier 25, may be inserted in the casing 10, as a unit, projections 28, which prevent any rotation of the barrier, sliding along a groove 35. A scalp plate 32 fits over the end of the plug 11. In place of the pin 46 for holding the key in the lock, a pivoted, or other type, detent may be used.

Title: Improvements in machines for trimming rubber or other articles
IPC: B29C37/02
Filed: 1920-07-28
Abstract: 149,631. Coquet, E. Aug. 12, 1919, [Convention date]. Cutting-apparatus with milling-cutters. - Moulded rubber or like articles capable of being rolled are fed along a guide against a rotary cutter which trims off the burr. A rotary cutter d of the milling type is connected to the shaft b kept in rotation by belt pulley gear c, c'. The cutter is housed within a cover g, which does not quite reach down to the table e, seen in plan in Fig. 2, but leaves a gap h through which an article u can reach the cutter. A strip f on the table and flush with it is set in close relation with the cutter. The border of the cover g serves as a guide against which the articles are rolled by the action of a disk n. This turns on the spindle p mounted in a lever r, which rocks about the centre s. The full line of this disk indicates the position when it first bears with frictional contact against the article u, the dotted line shows its position when at its maximum distance from the guide g. A spring v keeps the article in contact with the disk n after it has left the guide g and so facilitates its delivery beyond the table e .... The disk n is driven by worm gear i, j, from the shaft b through a spring band m which brings the disk against the article to be trimmed, but allows the lever r to swing on its pivot s as required. In a modification, an endless band replaces the disk n. The cutter may be shaped to suit the shape of the article to be trimmed.

Title: Improvements in dyeing processes
IPC: D06B5/00
Filed: 1935-08-19
Abstract: Silk, cotton goods, yarns, or the like material is dyed by subjecting it in a suitable chamber to a vacuum, introducing the dye liquor into the chamber from a reservoir under vacuum, and then introducing air under atmospheric pressure into the chamber to force the liquor into the fibres of the material.  The liquor may be returned to the reservoir by the atmospheric pressure in the chamber, and the dyed material may be centrifuged without removing it from the chamber.  If desired, during the centrifuging treatment of the material in one impregnating chamber, the dye liquor from the reservoir may be treated in a second chamber.  The apparatus employed may comprise a number of <PICT:0450198/IV/1> dyeing chambers 8, 10 and a dye liquor reservoir 11.  Each chamber 8, 10 comprises a cylindrical shell 16 with a corrosion-resisting lining and a spherical bottom forming a sump 18.  Conduits 20, controlled by valves 21, 22, control the flow of liquor between the reservoir 11 and the chambers 8, 10.  The top of the reservoir 11 is integral with the chamber and is provided with a manhole 24 and cover 26, and a vacuum may be established therein by a conduit 29 connected to a vacuum line, and a valve 30.  The removable covers 31 of the chambers 8, 10 carry conduits 38 having valves 36, 39 adapted to engage a vacuum line.  A centrifuge 37 comprising a perforated basket secured to a rotatable shaft 40 driven by bevel gears 51, 52 is disposed in each chamber 8, 10. The baskets are filled with the material to be dyed and the chamber 11 is fitted with dye liquor.  The valves 21, 22 are closed and the chambers 8, 10 and reservoir 11 are evacuated until a high vacuum has been obtained. The valves 30, 36, 39 are then closed and valve 21 is opened to allow the dye liquor to run into the chamber 8 and is forced into the material by closing valve 21 and opening the valve 36 to admit air under atmospheric pressure. After a period for treatment the valve 21 is opened and the dye liquor is forced by the air pressure in the chamber 8 through the conduit 21 into the reservoir 11.  The valve 21 is next closed and the material is centrifuged to remove excess liquor.  The dye liquor in the reservoir 11 is subjected to a vacuum before each treatment.
