Abstract: 1285589 Sheet forming DEMAG AG 4 Nov 1969 [20 Dec 1968] 54062/69 Heading B5A [Also in Division B8] In a packaging process, the leading end of a sheet 2 drawn from roll 1 is punched with edge holes by punches 4 and severed to form a blank 7 by knives 5. Each blank is then engaged at its edge holes and passed by a reciprocating conveyer 8 through a series of heating, moulding, filling, cover applying, sealing and blanking stations B, C, D, E, F, G respectively. The engagement of each blank by its edge holes enables the blank to be accurately located in each station and'in particular, where the sheet is printed, the print will be registered correctly at the moulding station. The conveyer comprises a pair of reciprocable pipes (13), Fig. (not shown), one located at each side of the sheet, each of which pipes carries spaced apertured supports (17) and within which is rotatably mounted a shaft (14) on which are mounted fingers (15) having pins (16) one finger being associated with each support. In operation, a blank is engaged at one station between one set of fingers (15) and supports (17) the pins (16) passing through the edge holes of the blank, and the pipes (13) are forwarded to bring the blank to the next station. The shaft is then rotated to release the blanks and the pipes moved back to their original position in readiness to receive the blank forwarded to the one station by the adjacent set of fingers and supports. In this way, by repeated reciprocation of the pipes a blank is forwarded through the working stations. Where a printed foil is used a photo-electric cell 6 is used to determine the length of feed past knives 5 in response to the printed image on the foil.

Abstract: 1441942 Closing bags RHEEM MFG CO 27 Nov 1973 54846/73 Heading B8C A plastics bag mouth, which is to be closed by a clip 5 forced by a punch 6 towards a die 3 on a support 2, is initially gathered and compressed in two mutually perpendicular directions. The bag mouth material is compressed in a first direction by an arm 34, which is pivoted at 32 to a pivotal gate 18 on swinging down of the gate, and is compressed in a mutually perpendicular direction by a plate 40 which is pivoted at 39 to one end of the arm. The bag mouth is pushed past the plate 40 which pivots upwardly against gravity to permit passage of the bag and then drops back. On actuation of a cylinder 28, the gate 18 is pivoted downwardly until a recess in the gate is brought adjacent a groove 4 in the support to define a clip guide channel. Concurrently with this movement, the arm 34 swings with its free end 35 sliding in a bracket 36 to compress the bag material against the die whilst the plate 40 compresses the bag in a transverse direction. The punch 6 is then actuated to apply the clip. On the return stroke of the cylinder 28, an ejector plate 45 is swung about a pivot 44 by the arm 34 to eject the clipped bag mouth from the die.

Abstract: 1,240,255. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORP. 14 Nov., 1969 [24 Dec., 1968], No. 55769/69. Headings HIT and H3. In order to reduce word current requirements in a thin film store a magnetic keeper 9 is positioned between a ground plane 3 and the storage elements. In the CEA store shown a copper ground plane 3 has deposited thereon insulating layer 8, Permalloy keeper 9, word line 6 and bit/sense line 4 sandwiched by thin magnetic films 2 and 5. When a current pulse is applied to word line 6 the amount of flux present in the magnetic circuit formed by film 2, keeper 9 and its extensions 9<SP>1</SP> is multiplied by the permeability factor of the keeper thus enabling the word drive current pulse to be reduced and still produce enough flux to switch the store. Since the bit line 4 is relatively far from the ground plane it has a higher impedance. The films may be CHA in which case the word and bit lines 6 and 4 are interchanged, Fig. 3 (not shown). In this case although the word drive current requirements are reduced the impedance of the bit line is smaller than in the CEA arrangement.
