Title: Apparatus for forming and conveying stacks of flat articles
IPC: B65H31/10
Filed: 1971-05-04
Abstract: 1327882 Forming and conveying stacks of flat articles WINDMOLLER & HOLSCHER 4 May 1971 [19 May 1970] 13019/71 Heading B8C Apparatus, for forming and conveying stacks of flat articles such as flattened bags, tubular sections, or sacks W, comprises a stack conveyer 1 on to which the articles W are successively thrown from the discharge end of a supply conveyer 19 to stack up against an aligning stop 12 while the stack conveyer 1 is not feeding, the stop 12 being movable out of the path of the completed stack St before the stack conveyer 1 is started to transport the stack to a discharge conveyer 10 and the conveyer 1 being intermittently lowered during stacking in dependence of the stack being formed. Located between the discharge conveyer 10 and the stack conveyer 1 is an intermediate conveyer 3 the upstream end of which is lowerable in unison with the stack conveyer 1 and the downstream end of which remains at substantially the same level as the discharge conveyer 10. With the conveyer 1, in its uppermost position and consisting of a plurality of parallel belts mounted in a vertically slidably mounted frame 4, as soon as the articles pile up on the conveyer 1 a sensor 13 on the stop 12 is struck by the following articles W to close a switch 14 which energizes a motor 27 to lower the conveyer 1 until the sensor 13 is released and lowering of the conveyer 1 is interrupted until the next few articles again press the sensor 13. When the number of articles, preset on an impulse generator 16, has been counted by a feeler 18 the generator 16 closes a switch which, through an adjustable time delay, operates mechanism 29 to pivot the stop 12 to an upper horizontal position above the stack St. Simultaneously an electromechanical clutch 35, Fig. 2, is operated so that the conveyer 1 is caused to rotate with the intermediate conveyer 3, which is continuously driven by a chain transmission 36 so that the conveyer 1 starts to feed the stack on to the intermediate conveyer 3. After the stack has passed a feeler 20 the motor 27 is energized to rotate in a direction which lifts the conveyer 1, elevation of the two conveyers 1, 3 terminating when an abutment 17 opens a switch 15. Release of the feeler 20 also pivots the stop 12 downwardly into the path of the next stack to be formed. The stop 12 is operated by a pneumatic cylinder 30 carried by a displaceable bearing 32 which can be clamped by a screw 33 on a frame 4 to set the stop according to the size of the article being stacked, the stop 12 being adjustable along a slot 21, the adjustment simultaneously moving the feeler 20 along a slot 22. The speeds of the conveyers 1, 3 and 10 are preferably equal.

Filed: 1948-05-12
Abstract: 653,567. Squirrel-cage constructions. MORAVIAN ELECTRICAL ENGINEERING WORKS, and KLIMA, V. May 12, 1948, No. 13029. [Class 35] A squirrel-cage rotor has part of each alternate slot made of larger sectional area than the next part along the slot while the other slots have the first part of smaller area than the next part and bridges are provided to bridge conductively the junctions of conductors in adjacent slots, the conductors also being of different sectional area. Fig. 3 shows a developed view of a rotor, the laminations of which are punched and grouped so as to form two parts 7, 8. Part 7 of the rotor laminations have large slots 5 and small slots 6 which correspond respectively to large slots 50 and small slots 60 in the other part 8 of the rotor laminations. A conductive ring 9 bridges all the conductors placed in all the said slots. Fig. 5 shows a modified form in which the conductor 60 in the part 8 is an integral portion of the axially-placed conductor 5 in the part 7, but said conductor 60 has a section area smaller than that of the conductor 5. In this modification, the conductors are formed by casting in the slots which are of different radial depth. There may be several sections of high crosssectional area and several of small area for each slot, e.g. as shown in Figs. 10, 12, 13 and the slots may be skewed. The conductors may be formed by casting.

Title: Improvements in and relating to self-regulating reciprocating pumps
IPC: F02M59/36
Filed: 1960-04-12
Abstract: 903,504. Fuel-injection pumps. BESSIERE, P. E. April 12, 1960 [Dec. 31, 1959], No. 13074/60. Class 102(1). [Also in Group XXIX] In a fuel-injection pump including a spring- loaded slide valve 7, Fig. 1, movable between a position of rest where it abuts a stop 18 and a position where it uncovers a discharge port 19 and also opens a by-pass conduit 6, to curtail pump delivery, means are provided to vary the distance between the stop and the discharge port in accordance with an operating condition of the engine, especially speed. The valve 7 moves upwardly against its spring 17 on the delivery stroke of the pump plunger 2 by means of a driving liquid delivered by an auxiliary pump having a piston 8 moving synchroneously with the pump plunger 2 and is braked on its return movement by means of a manually-adjustable throttle 22 through which at least part of the valve driving liquid returns to the chamber 9 of the auxiliary pump. On increased engine speed and hence increased pump speed, the distance between the valve 7 and the stop 18 correspondingly increases before the next delivery stroke of the pump takes place so that the port 19 is opened earlier with a consequent earlier curtailment of pump delivery and reduction in the amount of fuel supplied to the engine to reduce its speed. A groove 25 in the throttle 22 connects the valve chamber a to a discharge duct 26 so that at low engine speeds, e.g., starting, the pressure beneath the valve 7 is insufficient to raise it and the whole pump delivery is supplied to the engine. The means to vary the distance between the stop 18 and the discharge port 19 comprises a spring-loaded piston element 30, Fig. 2, formed with a cam 27. Pressure liquid supplied by an engine driven gear pump 32 which conveniently is the fuel supply pump supplying both the fuelinjection pump and the auxiliary pump acts on the piston element 30. As engine speed increases or decreases a slide valve 38 controlling a leak-off port 35 is more or less opened to control the pressure acting on the piston element 30 in accordance with speed to adjust the position of the stop 18. The cam is formed with a surface made to correspond to any torque requirements of the engine. The cam may have a plurality of surfaces corresponding to a plurality of conditions and is then rotated to select the desired set of engine torque conditions.

A continuous rod cigarette making machine comprises means 16 to impel cut tobacco into a duct 19 and at an angle thereto, suction means at the entrance to the duct, a second duct 24 communicating with the suction means, and a pump 23 to draw an air current through the means 16 and duct 24 to turn the tobacco particles, which are fed by a fast-rotating picker roller 13, through an angle into the entry of the duct 19. The duct 19 terminates at one portion of a conveyer 41 located adjacent a suction chamber 22 from which air is drawn by a pump 32 via a duct 33. The tobacco particles are thus accelerated through the duct 19 and are retained on the conveyer 41 by the airflow through said one portion, and by the airflow from atmosphere through another portion of the conveyer located beyond the duct 19. Substantially the whole of the air drawn through the pump 32 is discharged through a conduit 34 to the atmosphere, whereas substantially the whole of the flow through pump 23 is drawn into the suction means 16 and duct 19 together with a substantial proportion of fresh air from atmosphere. In the construction shown, pump 32 discharges through a dust separator 39 to a battery of cyclones 35. A dust extractor 25 is also provided in the duct 24. Conduits 36, 40 lead from the extractors to the ducts 33 and 19 respectively for the respective passage of dust and shorts. The air flow from pump 23 passes to a manifold 27, thence to a diffuser 28, and discharges through a louvred expanded-metal cover in a direction towards a perforated plate 37 adjacent the means 16. Chambers 30 and 38, located as shown, serve to receive any shorts. Specifications 895,733, 909,222 and 916,141 are referred to.

[Class 4.] An aeroplane or other aircraft has the passenger seats capable of being lifted and swung through folding doors in the sides of the cabin and then dropped by mechanism operated by the pilot, the seats being connected to parachutes. Fig. 1 is a diagrammatic plan ot a passenger cabin having seats 3 arranged in pairs on each side of a central gangway on pedestal arms 5. The whole of the mechanism is operated by an endless chain 63 moved by a lever in the pilot's cabin, the chain having a dog 64 for successively engaging a series of levers and being associated with pressure rollers 130 for bringing one reach of the chain into engagement with sprockets 128 whereby the following sequence of operations is effected. The chairs of the rearmost pair are first caused to approach one another to enable doors 4 comprising hinged parts 30, 31, Fig. 13, to be opened by turning inwards about pivots 33 until the two parts are folded together as shown in dotted lines to the left of Fig. 1. Connections from the door hinges during this movement cause the arms 5 to swing the chairs outwards through the door openings and the chairs to be unlocked from the arms 5. Cables 104 are then wound on drums 126 turned by the sprockets 128 to raise the seats which have sling links normally lying against the arms and seat back, the cables passing through tubular davits 95, 96 pivoted on the sides of the cabin. The davits are then swung outwards until hooks 105, Fig. 13, are opened by cables 110 of fixed length whereupon the seats fall and cable connections 117 in casings normally connected by press buttons 116 to the davits and in similar casings connected to the cabin wall and seat back, strip off leather covers 115 from openings beneath the doors to withdraw parachutes. The same sequence is then gone through with each succeeding pair of chairs, connections being provided for successively reclosing the doors corresponding to the preceding pair. The unlocking cf the seats from the arms 5 is effected by a shaft rotated by chain gear in each pedestal arm, the shaft having a non-circular upper end which engages a hole in a plate 20, Fig. 13, to turn it until it is clear of hooks 22 on the pedestal arm. The cables 104, 110, 117 pass normally through a notch 113 in the door opening to each chair.
