In a conveyer system for delivering articles, e.g. garments carried on hangers 29, to any predetermined one of a series of stations 1 ... 48, each transverse member 15 has a vertical limb 15b having spaces marked 1 ... 48, on the appropriate one of which each hanger is placed between fingers 31a depending from an endless chain 31 which moves through a distance corresponding to one space as the conveyer travels from one station to the next. The shaft 23 of one sprocket, around which the chain 31 passes, is connected by bevel gearing to a spindle 26 having fingers 27a extending therefrom. These fingers are engaged in succession by a series of fixed projections 28, one of which is situated between each pair of stations. The rotation of the sprocket caused by each engagement is sufficient to cause displacement of the chain 31 through one space with consequent movement of each hanger one space to the left. At each movement the hanger in space 1 falls on to the horizontal limb 15c in which position it is engaged and removed from the conveyer by an inclined pick-up rail 30. Each transverse member may support two endless chains 31 arranged end-to-end and driven in opposite directions.

Title: Improvements in or relating to kilns or ovens for firing pottery or the like
IPC: F27B9/40
Filed: 1945-07-18
Abstract: 603,452. Automatic control systems for pottery kilns. MEAD, E., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 18, 1945, No. 18430. [Class 38 (iv)] Temperature control.-An automatic temperature control system for pottery firing kilns acts by varying the tappings on the heating element supply transformer instead of switching selected elements in and out of circuit. As shown, temperature responsive switches f, r close respectively at the upper and lower limits of the range within which the temperature is to be controlled and energize the operative coil F or R of an induction relay similar in construction to a shaded pole watt-hour meter. Coil TP forms one winding of the relay and also of a transformer having a secondary winding TS supplying relay coils F or R, the field of which combines with the field of TP and causes the relay rotor to turn in a forward or reverse direction, to close contact F1 or F2 and to energize the tap changing 3-phase motor M through relay CF and contact CF1, or relay RF and contact RF1, to vary the heater tappings in the appropriate direction to readjust the temperature. On motion of the tap changing arm, contact S1 is closed and S2 is opened, locking in relay CF or RF through contacts CF2 or RF2, and disconnecting the temperature responsive switches. The relay rotor is restored to normal by the opposite winding to that initially operative, which is energized through arm A, resistance RS, and segment SF or SR when the relay rotor is off normal. On completion of a tap change, S1 opens and S2 closes, stopping the motor and restoring the control circuit so that if contact F or r is still closed a further tap change is initiated. A delay between tap changing operations may be introduced to allow for the thermal capacity of the kiln by delaying the closure of S2 after tap changing. Relays CF, RF may have additional circuits for manual operation.

Filed: 1917-12-13
Abstract: 129,735. Sperry Gyroscope Co., (Assignees of Bassett, P. R.). Dec. 18, 1916, [Convention date]. Arc lamps. - In a searchlight employing currents of about 40-90 amperes, flamearc electrodes are arranged so that a narrow part of the negative flame brushes the tin of the positive electrode P without enveloping it, and the arc is thus prevented from spreading over the side of this electrode. The arc for this purpose is short, say under “ in., and the negative electrode N is displaced through 30- 60 degrees from alinement with the positive, the negative point being in line with, or just below, the positive core. A positive electrode of small diameter, say ¢ in., is used, and preferably has an easily-combustible shell causing rapid " spindling " so that its nearly flat arcing face is only slightly larger than the core and has a high intrinsic brilliancy. The positive electrode has a core containing rare-earth salts. A silica or other refractory sleeve 11 restricts combustion of the positive electrode to the neighbourhood of the arc. Rotation of the positive electrode promotes symmetry of spindling and formation of a concave side 6. The negative electrode may also be rotated. Electric pressures of 42-45 volts are sufficient.
