Abstract: 789,013. Hoist position indicators. ENGLISH ELECTRIC CO., Ltd. March 8, 1956 [March 11, 1955], No. 7211/55. Class 78 (5). A hoist position indicator 22 for mine cage 15 comprises actuating means 27 for actuating the indicator independently of the hoist, and corrective control means 29 therefore arranged to adjust the indicator if, when the cage is stationary at a predetermined level, there is a discrepancy between the indicated level and the actual level (e.g. due to creep of the rope around Koepe pulley 10, the adjustment being made when the creep exceeds a predetermined high value and reducing it to a predeterminedlow value. Fig. 1-Koepe pulley 10 on shaft 100 is driven from hoist motor 12 through reduction gear 13, the said shaft in turn driving the safety controls through gearing 18, shaft 17, differential gear 19, shaft 20, and gearing 21, to operate indicator 22, remotely-positioned indicator 26 (through selsyn units 23 and 25) and automatic protective device 24. The corrective control means 29 is connected through shaft 64 to shaft 20 by gearing 30, shafts 17 and 20 forming two elements of the differential gear 19, the third element thereof being driven by said actuating means 27 through clutch 33. The adjustment or correction is initiated by said means 29, which starts motor 27, operates clutch 33, advances plunger stop 87B into non- effective engagement with brake disc 87C so that, one element of gear 19 being held stationary by the stationary hoist, the other element is operated by motor 29 to drive the indicators 22 and 26, and device 24 in the sense which corrects them. Fig. 2-The corrective control means comprises two similar units, respectively for the two senses of creep, consisting of slip-ring 62 and commutator 60 fixed together and connected by conductor 65, and slip-ring 63 and commutator 61 similarly fixed and connected together, the whole being rigidly mounted on shaft 64 for rotation together, the shaft being driven from gear 30 (see above). Contact is made to the slip-rings by fixed brushes 69 and 71, and to the commutators by fixed pairs of brushes 67A, 67B and 68A, 68B. The critical position occurs when the displacement between shaft 64 and brushes 68A, 68B is such that both brushes contact conducting segment 61B. Current then passes between the supply conductors 70A and 70B to operate relay 85 which initiates the motor 27 (Fig. 1), to perform the correction. The relay 85 also operates switch 85B. The shaft therefore rotates in the reverse direction until brush 68B is clear of segment 61B, at which point the motor 27 is switched and similarly, if brushes 67A, 67B contact conducting segment 60B a similar but reverse correction occurs. In other embodiments, a single commutator may be used, and the differential gear may be omitted and an additional clutch used.

Title: Improvements relating to drying processes and apparatus
IPC: F26B21/08
Filed: 1940-04-22
Abstract: 535,992. Drying systems. HIRSCH, M. April 22, 1940, No. 7213. [Class 34 (ii)] Moist material to be dried passes through a metal-walled chamber 2, Fig. 1, from 3 to 4 and is dried by a counter-current of gas circulated by fans 5, 8, through a jacket 9 back to the end 4. The moist gas passes over heaters 10 and takes up additional moisture from the entering material. An insulating space 12 surrounds the heaters 10. The gas in passing through the jacket 9 gives up heat to the gas within the chamber 2 and deposits moisture which is withdrawn. The gas is further cooled and de-humidified in apparatus 13 before re-entering the drying chamber. In a modification, heat exchange between the returning heated gas and the drying chamber is effected by gilled pipes 2, Fig. 2, through which the returning gas passes. These pipes are insulated at 12 from the heaters 10, and at the opposite end are surrounded by the coolers 13 or adjacent to cooling jackets 15. Fig. 3 shows a modification for drying a sprayed solution 3. The drying gas passes upward through the spray, receiving heat from the jacket 9 through the wall 2. The cooled gas is re-heated by heaters 10 surrounded by insulation 12 and circulated by fan 5 through jacket 9 and cooler 13. The dried material passes out at 4 and the condensed moisture from the gas at 16. The moist material may be pre-heated at 17 and may be used to heat the drying gas in place of the heater 10. In an alternative, Fig. 4 (not shown), the cooler 13 may be arranged at a lower level, so that the cooled and de-humidified gas is reheated by an extension of the wall 2 before reentering the drying chamber. In another modification, Fig. 5 (not shown), the arrangement is similar to Fig. 1 but the moist material and the drying gas pass through the drying chamber in the same direction.

Abstract: 585,822. Forging-machines. OMES, Ltd., and MORA, G. April 20, 1944, No. 7361. [Class 83 (iv)] In an electric upsetting-machine, the electrodes and ram cylinders are supported between guide bars upstanding from opposite ends of the base. Heads 17, 12 supported at opposite ends of the machine by the base 11 are integral with the upsetting cylinder 18 and abutment cylinder 13 respectively. Tie-rods 14, 15 extending between the heads act as guide bars for the ram heads 39, 42, the vice casting 22 and the work steady 61 if such be employed. A third rod in the horizontal plane of the rod 15 and the vertical plane of the rod 14 may be employed. Nuts 37, 38 on rods 35 carried by the head 17 determine the stroke of the ram 19 and similar nuts on rods 48 carried by the head 42 determine the stroke of the ram 16. The rods 48 pass freely through the head 12. The upper rod 14 is arranged to the rear, and the lower rod 15 forwardly of the machine to facilitate insertion and removal of the work. The connections to the lower vice electrode jaw 27 and upper jaw 30, movable by a hydraulic cylinder 28 are arranged at the rear of the machine as indicated in Fig. 2, and the transformer (not shown) is mounted adjacent their connections which are so arranged that the current paths to the two jaws are equal. The die 21 forms the other electrode and it has a terminal block 47 in the same plane and close to the connections for the jaws 27, 30. Current is thus fed symmetrically and the work is evenly heated. The ram 16 is controlled to recede as upsetting progresses to provide space for a head of the size required. The arrangement of the transformer connections is described in Specification 585,823, the vice jaws may have removable inserts as in Specification 579,474, and the steady may be constructed as in Specification 585,825. For upsetting at an intermediate point, two vices are employed, and these form the respective ends of the secondary.
