Title: Indexing mechanism for a rotary machine table
IPC: B23Q16/06
Filed: 1975-04-29
Abstract: 1508801 Linkwork ARMYTAGE BROS (KOTTINGLEY) Ltd 29 April 1975 [30 Jan 1974] 04253/74 Heading F2K A linkwork mechanism for rapidly indexing a rotary table 9 in a glass making machine progressively slows at least the latter part of the movement of the table 9 as it approaches the index position to prevent shock as the table is brought to rest. As shown, a pivotally anchored hydraulic jack 1 has its ram 2 pivoted at A to one end of a 1st link 3 whose other end is fast on a shaft 4 pivotally positioned at a fixed centre B. The shaft 4 is also fast with one end of a 2nd link 5 whose other end is pivoted at C to one end of a 3rd link 6 the other end of which is pivotally connected at D to an index arm 11 carrying a reciprocable index drive device 7. In operation the device 7 can engage one of a series of index blocks 8 spaced around the table 9 which rotates about its axis T. At the start of the indexing movement the jack 1, 2 acts via link 3 to move the links 5 and 6 from their initial i.e. relatively angular position (shown dotted in Fig. 1) to the mutually aligned position at the limit of their extension from pivot B (shown in full in Fig. 1), in which position they arrest the rotation of the table 9 in its fully indexed position. The indexing movement of the table is thus effective to commence with a rapid initial acceleration and progressively slow down at the end of the movement as the table is brought to rest without shock as the pivot point C of link 5 moves along arc Y. On completion of the index movement, a locking device 10 carried at the end of a ram 12 of a second hydraulic jack 13 engages the indexed block 8 to lock the table 9 in its indexed position, a nose 10A on the device 10 pushing back and releasing the index device 7 from the block 8 to allow the index ram and linkage mechanism to return to its starting position. The pivotal axes E for the jack 1 and B for the link 5 are arranged as eccentric pins to permit accurate setting and alignment of the mechanism. Also, effective length of the linkage mechanism and/or the stroke of the index ram may be adjustable to vary the angular movement of the table at each indexing.

Title: Improvements in humidifying systems for air and gases
IPC: F24F6/06
Filed: 1933-02-13
Abstract: 415,093. Humidifying air &c. GLANVILLE, W. H., and ROCKLIFFE, S. C., Building Research Station, Garston, near Watford, Hertfordshire. Feb. 13, 1933, No. 4322. [Class 55 (ii).] In a humidifying apparatus for air &c., the gas is passed over a heat-exchange means under thermostatic control, and then through a liquid spray, the temperature of which is maintained constant by direct thermostatic control. Air is drawn over precooling and preheating coils F, G respectively which are controlled by a thermostat H at the exit of the chamber A. The air then passes through mixing baffles J to a spray compartment K wherein water is discharged at a constant rate through nozzles M. A thermostat P located in a trough Q fed by the spray is adapted, when the temperature rises, to actuate a pump S and circulate the spray water from the reservoir O through a cooling-chamber T; or cooling coils under the control of the thermostat P may be situated in the reservoir. Excess moisture is eliminated by plates L and the air, drawn by a fan B, flows up a duct U, and either past a main heating unit before distribution, or through distributers and auxiliary heating units. A positive temperature difference is maintained between the thermostats P and H so that the sprayed water always tends to increase in temperature.

Filed: 1931-02-16
Abstract: 371,985. Cleaning metals; magnetic separators. BUDD MANUFACTURING CO., E. G., 2500, Hunting Park Avenue, Philadelphia, U.S.A.- (Assignees of Kelley, G. L.; 2500, Hunting Park Avenue, Philadelphia, U.S.A.) Feb. 16, 1931, No. 4818. Convention date, Feb. 20, 1930. [Classes 72 and 82 (ii).] In cleaning metal sheets oil is applied to the sheets, the used oil being cleaned, preferably by passing it through a magnetic separator and a settling tank, and then re-used, a thin film of oil being left on the sheets after cleaning to protect them against corrosion. The process is particularly applicable to removing metallic particles formed when welded sheets are smoothed. Metal sheets 52, Fig. 5, are passed through adjustably mounted rotating cylindrical brushes 52<1> and under spaced guide struts 30 on to a downwardly moving conveyer 13 consisting of belts or chains passing over sprocket wheels 15, 16 on shafts 18, 19 respectively. The shaft 19 also carries sprocket wheels for the chains of an upwardly moving conveyer 14 the upper end of which passes over sprockets 17 on a shaft 20 which is driven through gearing from a motor 23. As the sheets are carried up by the conveyer 14 they are sprayed with oil from nozzles 35a, 35b, 36a, 36b on pipes 35, 36 arranged in pairs above and below the conveyer. The sprays converge on to the sheets and are directed downwardly so that surplus oil drains off the sheets into a sump 41 beneath the conveyers having a discharge 42 at its lowest point. After passing the oil sprays the sheets are carried by delivery rolls 31 to wiping rolls 32 covered with felt 33 which is protected by a covering 32a of woven cloth. More than one pair of wiping rolls with or without a pair of non-rotary wipers 34 may be used. The used oil draining through the discharge 42 passes into a magnetic filter 46, Fig. 1, containing magnets 48, permanent or electromagnetic, where metallic particles are removed and then through a conduit 43 into a tank 40. A settling tank 47 with spaced baffles 49 may be used, preferably shunted off the conduit 43 by pipes 50, 51. A pump 44 driven by a motor 45 draws the clean oil from the tank 40 and passes it through pipes 39, 38, 37 back to the oil sprays.
