Filed: 1935-07-27
Abstract: 462,291. Guided skip hoists ; loading skips ; delivering material from hoppers. BIRTLEY CO., Ltd. (Roberts & Schaefer Co.)- July 27, 1935, No. 21404. [Classes 78 (i), 78 (iii), and 78 (iv)] [ Also in Group XVIII] Skip-loading apparatus comprises a receptacle or measuring chamber 2 between the main hopper 1 and the skip-loading gate 4, the entry to the chamber 2 being- controlled by a gate 3 which is at all times wholly within the main hopper and /or the said chamber, the gate 3 being closed automatically by the descent of the skip and opened automatically by the ascent of the skip. When the skip 5 is above its loading position, as shown in Fig. 4, the gate 3 is open and the gate 4 is closed. As the skip descends a guide 7 thereon engages a roller 8 and closes the gate 3, keeping this gate closed during the further descent of the skip. A second guide 9 on the skip releases locking gear 10 of the gate 4, so that when the skip reaches its lowest position the gate 4 opens and discharges the contents of the chamber 2 into the skip. When the skip ascends, rollers on the lower end of the gate 4 are engaged by the skip and cause this gate to close. While it is held closed, the guide 9 allows the catch 10 to fall and secure the gate in the closed position. The gate 3 between the main hopper and the chamber 2 is then opened when the guide 7 engages a roller 11 connected to the gate. When the gate 3 is open the space between this gate and the bottom plate 13 of the chamber 2 is wider at its lower end than at its upper end, as shown in Fig. 4, so that there is less tendency for material to jam at the back of the gate. The gate 3 may be formed with a flat floor by means of an additional plate 14, Fig. 5.

Abstract: 386,258. Coke ovens. STILL, C., Recklinghausen, Westphalia, Germany. July 29, 1932, No. 21421. Convention date, Aug. 24, 1931. [Class 55 (i).] In the joint operation of several coke ovens which have means for withdrawing distillates from the interior and the exterior of the charge, the pressure in the gascollecting spaces over the charge of those ovens in the initial stages of carbonization is equalized by the pressure in those spaces of the ovens in a more advanced stage, by the use of a pressure equalizing chamber or main through which gas is withdrawn whereby a constant vacuum may be created in the interior of the coal charge.. This vacuum, which is maintained constant, is adjusted from 40 to 300 mm. of water according to the resistance of the plastic layer in the charge. The gas collecting spaces of ovens a are continuously connected to a common pressure equalizing and gas withdrawal main c by conduits b. A pressure valve g regulates automatically the withdrawal of the gases from the collecting spaces. The distillates from within the charge are withdrawn by suction through conduits d, e, f by a pump i, a throttle valve h being adjusted so that the pressure in the main c is kept constant. The pressure in the main c is controlled by a gas regulator (not shown) which may actuate the throttle h, or control the pump i.

Title: Record changer
IPC: G11B17/16
Filed: 1955-07-26
Abstract: 797,815. Automatic gramophones. THORENS SOC. ANON. July 26, 1955 [Aug. 28, 1954], No. 21612/55. Class 40 (2). In a centre-post type recordchanger, a steadying arm 27 for the records on the stack is automatically set in position at the setting-in operation of the record-changer and automatically disengaged after the playing of the last record on the stack. When records have been loaded on to the centre-post and the motor switched on, an automatic cycle is initiated by a further movement to a " Reject " position which trips a normal type tap-tap lever 93 and causes it to remove an arm 22 supporting a toothed segment plate 18 which thereupon completes the toothed periphery of a cam-wheel 17 having a notch therein in which a continuously rotating gear 8 idles. The wheel 17 carries cams controlling the pick-up arm movements and record release in known manner, but in particular controls the swinging in and lowering of arm 27 which is supported on a shaft 28 having a pin 32 sliding in a slot 33 in a stationary member 31. The arm 27 is held initially up and away from the records by means of a horizontal part 36 of the slot 33. Initial rotation of the cam disc causes cam d to rotate shaft 28, via a lever 52, rod 51 and a rotatable element 50 having a forked portion 49 engaging a pin 48 in the shaft 28. The amount of the initial rotation of shaft 28 is sufficient for the pin 32 to enter the vertical slot 33 so that the arm 27 drops on to the stack of records. After the last record has fallen to the turntable the arm 27 and shaft 28 slides downwardly and a pawl 45 becomes latched out by a wire 46 ready for the next automatic cycle. When this is initiated a laterally resilient lever 43 operated by cam c lifts shaft 28 to a position in which pin 48 enters the forked portion 49 of element 50 which is rotated by, cam d to swing the arm 27 clear of the records. This motion is linked via an arm 56 and a bell-crank 76 to a stepped member 71 to bring its surface 81 into the path of an ear 75 on an arm swinging with the pick-up whereby said pick-up arm is prevented from being swung back over the records. The arm 56 at the same time also switches the motor off through the medium of a lever 59, rod 62 and switch member 63. The stepped member 71 is normally swung to cause one of its surfaces 72, 73, 74 to intercept ear 75 to control the setting down position of the pick-up under the control of a detector member m, operated by a falling record. Specifications 638,749, 664,619, 690,571 and 738,449 are referred to.

Abstract: 460,892. Cooling resistances. EXPANDED METAL CO., Ltd., and HAMILTON, B. H. N. H. Aug. 1, 1935, No. 21855. [Class 37] A motor-starting or like control circuit comprises one or more air-cooled expandedmetal resistances or similar resistances of high wattage dissipation per unit weight, which are force cooled by normally inoperative means during periods in which the current loading is heavy. As shown applied to a starting-resistance for a series motor 6, a motor 1 drives a fan 2 which forces air on to the resistance elements 3 to cool them. The motor 1 is energized in dependence upon the voltage drop across the resistance elements 3. As shown, the fan motor 1 is energized through a voltage operated relay 5 connected from the mains 4 across the resistance. When the resistance is cut out in steps by the starting- switch, the circuit of the motor 1 may be arranged to be automatically completed until a predetermined number of steps have been cut out, and then open-circuited. In motorstarting apparatus with time control, such as a dashpot, this may also be used to control the cooling motor. Similarly where current or voltage control is employed, current or voltage actuated relays may be employed for controlling the cooling motor. The resistance elements may be housed in a container through which air is driven or drawn by the fan 2.
