Abstract: 1322423 Handling bobbins on endless conveyers; marking bobbins MACHINEFABRIEK M BROUWER & CO NV 23 June 1971 [30 June 1970] 29339/71 Headings B8A and B8M [Also in Divisions G1 G4 and H1] Bobbins of thread 1 have a marker band 4 a particular distance from one end 3 indicating the colour of thread. The band may be of conductive material and sensed by two contacts or it may be a twin band of two colours or of different reflectivities and sensed photo-electrically (see abridgment Divisions G1 H1). The band may be a coloured or reflective band. The bobbins are carried from a supply box (not shown) by a feeder 25, having a conveyer 26, to a slanting gutter 27 and thence on to a ridged conveyer 32. Movement of the conveyer 27 is controlled by photo-cells 30 sensing the height of bobbins accumulated in the gutter 27. The bobbins are conical in shape and an arm 32 pushes those bobbins not having the narrow end on the farther side of the conveyer (as shown in Fig. 4) to the opposite side where a series of pneumatic actuators 37 flick the bobbins over as they are contained within guides 36 on frames 35a, 35b driven by drums 34a, 34b in synchronism with the conveyer 32. A further arm 9 then pushes the now all similarly aligned bobbins to the far side of the conveyer where a series of sensors 10, positioned on rods at dif-  ferent positions along the bobbins length, sense the presence of a marker band at charac-  teristic positions along the bobbins. A sensor on sensing a marker band operates a pneumatic  ejector to push the bobbin into a corresponding j gutter 24.

Title: Device for Transferring Articles from a Feed Conveyor to a Continuously Moving Receiving Conveyor.
Inventor: RAFAILSKY FELIX GRIGORIEVICH
IPC: B65G47/52
Filed: 1968-06-20
Abstract: 1,171,039. Endless conveyers. UKRAINSKY NAUCHNO - ISSLEDOVATELSKY I KONSTRUKTORSKY INSTITUT PRODOVOLSTVENNOGO MASHINOSTROENIA UKRNIIPRODMASH. 20 June, 1968, No. 29499/68. Heading B8A. In transferring sweets from a feed conveyer 6 to a continuously-moving receiving conveyer 53 by an intermediate carrier element 28, adapted to receive a sweet from the feed conveyer, drive means for the latter is so constructed that the carrier 28 moves from the feed conveyer to the receiving conveyer 53 with a chage in its speed and direction of movement to a direction and speed corresponding to those of the receiving conveyer 53. As shown, the conveyers 6 are associated with three respective intermediate carrier elements 28. Transferring sweet from conveyer 6 to carrier element 28.-A respective pusher 13 is laterally movable on a guide rod 18 relative to each conveyer 6 under the action of a spring 20 when the guide rod is deflected by a cam 22 to remove a stop 19. If a sweet is not correctly positioned relative to the pusher 13, a signal is transmitted (by photoelectric or other means not shown) to a member 17 which is thereby lifted so as to obstruct a member 15 connected to the associated pusher 13. When the pusher 11 leaves its normal position on the belt 6 (Fig. 4) to push the sweet into the carrier 28, an arm 25 normally resting on the pusher 11 is drawn down by a spring (not shown) to block the passage of further sweets on the belt 6. Movement and mounting of the carriers 28.- Each carrier 28 is mounted on a bar 26 which is rigid with rods 36, 36, vertically slidable in guides 44, 44, under the action of a cam 43. The guides 44, 44, are part of a frame 45 which is horizontally slidable (under the action of a cam 49) in guides 46, 46, fixed to the machine frame. When the sweets are located in the carriers 28, the bar 26 commences a downward movement. This causes a lug 33 of a sweetholding arm 32 of the carrier 28 to become disengaged from an abutment cam 35. This releases the arm 32 so that it can drop under spring action, into engagement (Fig. 5, not shown) with the sweet. Transfer of the sweet to the conveyer 53.-The latter comprises an endless coneyver chain 54 having a series of spaced carriers 52. These are slotted so as to interfit similar slots on the carriers 28. The downward movement of the bar 26 brings the carriers into alignment with the direction of movement of the carriers 52. The frame 45 moves in the latter direction but does not reach the same speed as that of the conveyer 53. Thus the carriers 52 pass through the carriers 28 (Figs. 6, 7, 8) leaving the sweets held positively in the latter by the action of a respective stop 60. The latter is actuated by an abutment 62 on the carrier 28 (Fig. 7) engaging a rod 61 carried by the stop 60. A sloping abutment surface X (Fig. 7) engages an abutment Y of the arm 32 to raise the latter at the moment of sweet transfer.

Title: Improvements in and relating to alternating-current electric motors
IPC: H02K17/24
Filed: 1922-07-25
Abstract: 209,848. Contell, F. July 25, 1922. Alternating-current motors; exciting.-A synchronous motor is driven at constant speed by supplying its rotor and stator exclusively with alternating-current derived from a single supply or two supplies of different and constant frequency, auxiliary windings being used in some cases for starting. The motor speed depends upon the relative direction of rotation of the rotor and stator fields. When the machine runs on a single supply the rotor and stator may be connected in series or parallel. Thus with a 50 and a 15 cycle supply available, a four pole motor will run at 3,000 and 900 revolutions per minute on the 5 and 15 cycles respectively, and when connected to both supplies it will run at 1950 and 1050 revolutions when the two fields rotate respectively in opposite or similar directions. Fig. 1 shows the connections for a machine having a main stator winding of p poles and an auxiliary winding of p/2 poles respectively connected at 4, 5, 6, 1, 2, 3 to mains A, B, C through switches N, M. The rotor has a winding of p poles connected through rings X<1>, X<2>, X<3>, and a switch P to the mains, and an auxiliary winding of p/2 poles which may be connected to a starter o. The switches are so linked that when M opens the contacts N, P close. The machine is started as an induction motor by the starter o with the switch M closed and is subsequently transferred to running on the windings 4, 5, 6 by opening the switch M and closing the switches N, P. For running on a low frequency supply, the auxiliary windings are omitted. Fig. 2 shows a machine having its stator connected to a high frequency supply D, E, F and its rotor brought out to a twoway switch I by which it may be started up as an induction motor on a resistance K and then be transferred to the low frequency supply A, B, C for permanent running. The switch I has " nicker " blades with ends so bevelled at their pivoted ends as to break the circuit at the required point in the throw of the switch. Reference has been directed by the Comptroller to Specification 11873/07.
