Title: Carton erecting apparatus
IPC: B31B5/78
Filed: 1974-03-19
Abstract: 1469170 Erecting cartons KOMBINERADE MASKINSYSTEM AB 19 March 1974 12154/74 Heading B8C Cartons are erected by a device having a sloping magazine 1, the slope of which is adjustable by bars 10 which pivot the magazine bodily about posts 7 carried by a stand 19. The stand supports a carriage which is reciprocable by a cylinder 20 and which carries a sucker 21, a sucker plate 24, and a pivoted stop 17. An erecting arm 22 is pivoted at one end to the sucker plate and at the other to one end of an adjustable joint arm 23, the other end of which is pivoted to the stand. An opener tongue 11, positioned to engage the upper edge of the leading blank 12, is located at the forward end of the magazine on a post 7 and the blanks are urged toward the tongue by a wheeled pusher 13. In operation, the sucker and sucker plate are forwarded to the position shown in phantom lines in Fig. 2, in which position the sucker engages the front wall of the leading blank. Withdrawal of the carriage pulls the leading blank from the magazine, this movement being initially resisted by the tongue 11 which first engages the top edge of the front wall of the blank and then slips over the edges to engage the back wall. Continued withdrawal of the carriage thus opens the blank until the tongue slips over the back wall into contact with the next blank. As the carriage moves to its rearmost position the stop 17 is raised and the arm 22 pivots to the position shown in solid lines in Fig. 2. This completes the opening of the blank, during which time the bottom flaps of the blank are closed. Finally the stop 17 is lowered and the erected carton pushed sideways out of the device by a pusher 18. Where the cartons have a top front flap, the preliminary opening of the blank is assisted by the tongue 11 which pushes the flap backwards into the back wall. The angle of the arm 22 to the sucker plate 24 in the rearmost position of the carriage is preferably just less than 90 degrees but may be varied by suitable adjustment of the joint arm 23.

Title: Improvements in and relating to electric motor control systems
IPC: B60L15/10
Filed: 1933-04-27
Abstract: 420,294. Field control of D.C. motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin) April 27, 1933, Nos. 12342 and 12343. Convention dates, April 27, 1932 and Sept. 21, 1932. [Class 38 (iii)] The series field current of a vehicle motor is diverted by the armature of a motor 8 which is connected across the field at certain controller steps, and at the time of its connection has a counter-electromotive force such that its resistance as a shunt is small, and which thereafter changes to increase its effective resistance. Motors 1, 2 are arranged for series-parallel and rheostatic braking control, and the diverter motor 8 is connected at the second controller step, and is effective only on the field 4 during the series stages. In the final speed stage a brake 11 may be applied to the motor 8 to give the top speed. This braking of the motor 8 may be under the control of a time relay energized on the last parallel step, and may be effective also when the controller is being moved to its " off " position. The motor 8 may be series, compound or separately excited, and may drive a flywheel or a fan. It is effective for all rheostatic braking stages. In a modification, Fig. 3, not shown, two diverter motors are employed alternately connected to the field and for short-circuit braking on successive controller steps. A further modification employs a single diverter motor which is reversed for each controller step. Alternatively, the field of the diverter motor may be disconnected during movement from one controller step, and reconnected when the next is reached. Specification 349,777 is referred to. The Specification as open to inspection under Sect. 91 comprises also arrangements in which relays controlled by the controller, and the diverted current, control short-circuit braking of the diverter motor between controller steps. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in couplings for fluid conduits
IPC: F16L33/01
Filed: 1958-04-18
Abstract: 855,836. Hose couplings. RESISTOFLEX CORPORATION. April 18, 1958 [April 30, 1957], No. 12402/58. Class 99(1). In a coupling for a tubular fluid conduit, e.g. for assembling a tubular nipple 22, Fig. 1, to the end of a hose 12, an annular sleeve 20 is provided with a resilient frusto-conical flange-like lip 70 arranged for flexing in the axial direction for engaging the nipple 22 on assembly so as to form a fluid-tight seal therewith the lip 70 being placed in a state of stress when deflected from its axially extending position in a relaxed condition and means being provided for limiting the movement of the nipple 22 relative to the sleeve 20 to prevent deflection of the lip 70 beyond a given position such that the lip 70 retains its frusto-conical configuration throughout the range of assembly. As shown, the hose 12 is provided with a wire braid covered liner 14 of inelastic plastic such as polytetrafluoroethylene. The sleeve 20 is inserted in the end of the hose between the liner 14 and the braid 16 until a shoulder 38 abuts the end of the liner. The sleeve is then screwed into a socket 18 placed around the hose 12 so as to grip the braid 16 between mating surfaces 26, 32 on the socket and sleeve respectively, screwing being by way of a wrench engaging notches in the inner surface of the sleeve. The nipple 22 is screwed into the socket 18 and is provided with a tubular barrel 46 which compresses the liner 14 against the bore of the sleeve and with a frusto-conical face 62 which abuts a correspondingly shaped seat 64 and the lip 70 integral therewith when screwing takes place. The lip 70 when unstressed makes a more acute angle with the sleeve axis than the seat 64, the latter serving to limit the movement of the nipple so as to prevent the lip 70 from snapping over. The nipple is formed at one end with a swivel nut connector 56. Alternatively, the abutting seat on the sleeve has the same inclination as that of the unstressed lip, or the resilient lip is formed on the nipple. In another embodiment, Fig. 6, a male connector 98 has a resilient annular reentrant portion 102 joined to an abutment 104 for cooperating with the seat 58 on the nipple when the connector is engaged by a swivel nut 90 secured to the nipple by a locking wire 94. In a further embodiment, not shown, the male connector is screwed against the flared mouth of a metal tubing with a hard metal annular ring interposed between the flared mouth and the resilient portion. Specification 826,220 is referred to.
