Filed: 1973-06-09
Abstract: 1420240 Drying elastomeric material US RUBBER RECLAIMING CO Inc 9 June 1973 27571/73 Heading F4G A process of drying wet elastomeric materials comprises the steps of advancing and compressing continuously supplied wet elastomeric material while venting water therefrom, recirculating by turning back a portion of the material during its further advance to release and expel additional water, further compressing the material, and then advancing the material against an outlet at an even greater pressure, i.e. 400 to 1200 lbs/sq inch, and at a temperature of 150 to 350‹ F. The apparatus for carrying out the process comprises a screw working in a tapered housing and fed from a hopper 12 by a ram 11. The pressure reduction step is achieved by the material passing a barrier 22 of the screw. Ploughs 30 are provided to increase turbulence in the material. Water passes out of the housing through a passage 35 and through a strainer 37. The outlet region 26 of the apparatus comprises a flaring passageway 40 leading to a pair of superposed screen plates 42, 44. A rotatable pelletizing knife 45 is provided. Various diameters of the feed channel are given as well as dimensions of the screen-plates. Fluid may be passed through passages 31, 32 to heat or cool the material.

Title: Improvements in or relating to metal-clad switchgear
IPC: H02B11/24
Filed: 1926-11-03
Abstract: 284,772. Davies, D. R., and Metropolitan-Vickers Electrical Co., Ltd. Nov. 3, 1926. Sliding-switch-carriage arragements.-Truck type switchgear in which the contact apertures on the fixed switchgear structure are automatically closed by shutters on withdrawal of the movable member and in which the shutters are locked against movement while the truck is withdrawn, have mechanisms for effecting such locking located within a hollow runway for the truck member operated by a member carried by the movable truck or by operating gear used for its withdrawal. As shown in Fig. 1 the contact apertures 4 on the fixed structure are closed by hinged shutters 5, 6 when the truck is withdrawn, the shutters being raised as the truck is moved into contacting position by an operating member 11 on the track 1 which engages pins 10, 32 on the lower shutter 6 which is linked to the upper shutter 5 by a bar 7. The bar 7 extends downwardly and bears near its lower end, which is carried by a pivoted link 13, a locking projection 18. This projection is engaged in the position shown by a projection 19 on a rectilinearly-sliding rod 20 moved by a pivoted cam 23 engaging a pin 22 thereon. As the truck is moved inwardly a depending arm 24 engages the end 27 of the cam 23 so that the cam is rotated and the rod 20 is moved to disengage the projection 19 from the projection 18 on the rod 7 so that the shutters are freed for operating when engaged by the projection 11 and the plug members 3 may pass into the apertures 4 and engage their corresponding socket members. Similarly the shutters are lowered over the orifices 4 and locked in this position during the withdrawal of the truck members. In a modification (Fig. 3, not shown) the truck member carries a single operating member for moving the shutters and also for engaging a locking pawl which prevents their operation when the truck is withdrawn. The locking mechanism may be arranged to operate automatically only on withdrawal of the truck, the unlocking of the shutters being effected by a separate key. Where the truck is withdrawn by a screw and nut mechanism the locking device may be operated by an independent floating screw or by a gear driven cam operated by such mechanism.

Abstract: 276,436. Marks, E. C. R., (Ohmer Fare Register Co.). May 28, 1926. Platen-impression arrangements; roller inking- arrangements.-A machine for printing and issu. ing fare tickets from a roll of strip, and at the same time printing a record of tickets issued upon a strip which is stored in the machine, comprises the following impression and inking arrangements. The ticket strip 94 is taken from a supply roll 95 over a cylindrical printing platen 90, and the record strip 96 is taken over a similar platen 89. These platens, together with a resiliently-mounted inking-roller 88, are carried by a frame 83 which is rocked about a pivot-shaft 44. When the actuating-handle 26 is turned through two revolutions, the frame 83 is oscillated so that the inking roller 88 inks the typewheels 30, the platen 90 presses the ticket strip 94 against the type, the inking-roller again inks the type, and the platen 89 presses the record strip 96 against the type. The platen-carrier shaft 44 is rocked by arm 43 and link 41 connected to the ratchet wheel 8 at one end of the main shaft 9 by a link connected to a disc on the shaft 9.
