Title: Shutter mechanism for cinematographic projectors
IPC: G03B9/10
Filed: 1964-09-02
Abstract: 1,036,667. Cine projectors; shutters. EASTMAN KODAK CO. Sept. 2,1964 [Sept. 6,1963 ], No. 35853/64. Heading G2E. In a cine projector, a high shutter frequency at low projection speeds for flickerless viewing is obtained by the use of a shutter comprising two co-axial three bladed discs 40, 42, which are superimposed at normal speeds when one of the discs is driven, but which are angularly displaced relative to each other at low speeds to provide a sixbladed shutter when the other disc is driven, the discs being interconnected by a lost motion pin and slot arrangement. Pull-down mechanism 44 is operated by a cam carried on shutter shaft 28 which is selectively driven at the two speeds through pulleys 30 or 32 by reversible motor 20, and to which disc 42 is fixed. The pulleys are belt driven at the same peripheral speed and having different diameters, rotate at different angular speeds. Slide bearings 54, 64 permit rotational and axial motion of the pulleys on shaft 28 between the retaining collar 46 and hub 76. Manual control 38 is pivotable at 52 to slide the pulleys, by means of member 48 slidable on shaft 28, against spring 82 to the low-speed drive position of Fig. 2 where pin 73 on pulley 32 drivingly engages pin 92 on ring 86 which rotates on hub 76. Spring 82 drives the pulleys to the left when control 38 is released for normal speed engagement of the pin 62 on pulley 30 with pin 58 on collar 46. Shutter disc 40 is fastened to ring 86 and the two discs are connected by pin 94 on disc 42 sliding within an arcuate slot in disc 40, and by tension spring 100 between pins 10,104 which is strong enough to keep the blades aligned at normal speeds for forward and reverse running. At low speeds, when disc 40 is driven, the angular separation of the discs produces the six-bladed shutter. In another embodiment, the pulleys are coupled together and are axially slidable to the two driving positions by the engagement of a control lever with a peripheral groove in one of the pulleys. The pulleys are held in either position by an overcentre toggle spring.

Title: Improvements in electric motor field control
IPC: H02P7/34
Filed: 1928-12-05
Abstract: 318,216. Marion Steam Shovel Co., (Assignees of Jacobs, H. S.). Aug. 31, 1928. [Convention date]. Exciting.-In order to start a D.C. motor with sufficient torque for a heavy load, as in the operation of power shovels, the motor N, Fig. 1, fed by a local generator B has a separately excited field I strengthened at the same time as current is switched on to a separately excited field J of the generator B. The generator exciter C, before the motor is started, delivers current reduced by a resistance 42 to a boosting field winding H of the motor exciter D, the motor being thus partly excited while still at rest. When the generator field J is switched-on through a reversing switch E to terminals 18, 19 of its exciting circuit, connection is also made across terminals 10, 19 to short-circuit the resistance 42, whereby the motor field strength and the voltage impressed on the motor armature rise to a maximum together. A number of motors may be connected to the generator and controller simultaneously in the same way as a single motor. To reduce the torque automatically as the motor speeds up, the motor exciter has a field-winding'M opposing the winding H and connected to a contact of the switch E so as to be switched-in across the motorarmature circuit. A regenerative braking effect due to quick discharge of the field J through a resistance F is obtained when the switch E is opened. Reverse drive with approximately constant motor field excitation is obtained by changing-over the switch E to the contacts 24, 25. Characteristic curves illustrating the different stages of control are annexed to the Specification.

Title: Method of and apparatus for regenerating spent ammoniacal cuprous solutions from gas washing processes
IPC: C10K1/12
Filed: 1933-12-22
Abstract: <PICT:0423762/III/1> Spent ammoniacal cuprous solutions containing dissolved carbon monoxide, carbon dioxide and ammonia are regenerated by heating the solution to expel all of the completely expulsible gases including a portion of the ammonia, scrubbing the expelled gases with an absorption medium such as cold water whilst allowing the carbon monoxide and part of the carbon dioxide to escape, heating the absorption medium to expel the ammonia and returning the latter to the ammoniacal cuprous solution.  As shown, spent solution is heated in a tank 20, carbon dioxide, carbon monoxide and a portion of the ammonia together with steam passing through a conduit 24 to a tower 26 where its ammonia content is absorbed by water supplied by a sprinkler 30.  The carbon monoxide is discharged at 32 while the warm ammoniacal liquor flows via conduit 36 into a still 34 down which it flows in counter current to steam introduced via a conduit 40. Ammoniacal vapours pass through a conduit 42 to a tower 46 where they ascend in counter current to the spent liquor proceeding from a gas washing tower 10 via a conduit 18.  The ammonia is absorbed by the spent liquor which then proceeds via a pipe 52 through preheaters 58 and 60 to the tank 20.  The regenerated solution passes from the tank 20 via a conduit 62 to yield up its heat to the preheater 58.  It is further cooled in coolers 70 and 78 and is finally returned to the gas washing tower 10 via a pipe 16.  The gases from the tower 46 proceed via a pipe 50 to the tower 26 where any ammonia they still contain is absorbed.  The hot ammonia-free water from the foot of the still 38 proceeds by a pipe 64 to heat the preheater 60.  The water content of the circulating ammoniacal cuprous solution may be maintained constant by suitably regulating the quantity of water supplied to the sprinkler 30 and/or the quantity of steam supplied through the conduit 40.  Reduction of the solution may be corrected by adding oxygen.  The ammonia may be returned to the circulating liquor at other points if desired, e.g. by introduction into the regenerated solution.  Alternatively, the still may be heated by steam coils or other source of indirect heat.

Title: Improvements in the electrical control of dental units
IPC: H02P7/288
Filed: 1964-09-04
Abstract: 1,049,496. Control of A.C. motors. CHIRANA PRAHA, NARODNI PODNIK. Sept. 4, 1964 [Sept. 6, 1963], No. 36278/64. Heading H2J. [Also in Division A5] An A.C. motor driving a dental drill has armature 8 and field winding 9, the latter being associated with resistor 3 for high-speed operation, and with resistors 2, 3 for operation at a lower speed. A selector switch 25 provides two speed-stages by connecting different portions of tapped resistor 1 in parallel with armature 8, a changeover switch 26 affording high or low speed operation in each stage. The motor is reversed by switch 27, the main source U2 having voltage stabilizing elements 6, 7 and 7<SP>1</SP> The motor is controlled by relay 19 whose coil is connected to low-voltage source UI through foot-operated switch 21. Alternatively, the relay-coil may be energized through manual switches 22, 23, associated respectively with the motor or a turbine, or a switch 24 mounted on a control panel. When the relay 19 is de-energized, a braking resistor 4 is inserted in the supply circuit to the motor whose armature is short-circuited. The duration of the braking period is determined by a time delay relay 18 which drops out after the relay 19 has been de-energized. When the electric motor is energized, electromagnetic valves 14, 15 are actuated for the supply of cooling fluid to the drill. When the electric motor is de-energized, valves 12, 13 may be actuated for driving the turbine and supplying fluid. Change-over switches 10, 11 are operated by placing the turbine in a holder, whereby the valves 12, 13 are disconnected and the motor circuit is prepared for operation. Some of the control switches may be mounted on a panel and placed on a movable arm for easy access. Time-delay relays.-In a modification, the relay 18 is controlled by a delay switch comprising a spring-loaded heated filament which expands to close a pair of contacts. When the relay 19 is de-energized, the time-delay in operation of relay 18 is determined by the period required for the reduction of length of the filament due to its cooling. Alternatively, the timing switch may comprise a bimetallic strip with a heating coil. In a further embodiment, the time delay is afforded by a tiltable mercury switch operated by a solenoid whose core is coupled with a piston in a dash-pot, Figs. 2, 3, 4 (not shown).

Abstract: 1414879 Burning pulverent materials F L SMIDTH & CO AS 22 Feb 1974 [31 July 1973] 36377/73 Heading F4B A rotary kiln plant for burning pulverous or granular material comprises a suspension preheater and rotaty kiln 1 having planetary cooler tubes 5 with both ends of the kiln provided with ducts leading to the preheater. Air is drawn in by fan 18, through a stationary casing 7, and cools material discharged from the shoots 6 as the material flows counter to the air in tubes 5 before discharge through the outlet 8. Heated cooling air is divided into a stream providing combustion air for the burner 9 that passes to the preheater via duct 11, and a stream that passes out of the burner end of the kiln and to the preheater via duct 21. Raw material from the inlet 19 is preheated by the hot gases in the heat exchangers and is discharged into the duct 21 from the cyclone 12 through the pipe 20. Fuel from pipe 23 is burned in rising heated cooler air in duct 21 and raw material is partially calcined during upwards passage to the cyclone 15 where it is separated from the hot gases and discharged through feed pipe 24 for final burning or sintering in the kiln 1. Some kiln exhaust gas may be by-passed via pipe 25 for control of alkali content of the final product. In a modified version of the apparatus, Fig. 2 (not shown); heated cooling air from the burner end of the furnace and the kiln exhaust gases from the other end pass through separate suspension preheater systems with preheated material from both systems flowing to the heated cooling air burning chamber (51) before discharge via duct (56) to the rotary kiln (31).
