Title: Improvements in packaging apparatus
IPC: B65B7/20
Filed: 1939-11-29
Abstract: 535,347. Packeting. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd. Nov. 29, 1939, No. 31047. [Class 94 (i)] Relates to apparatus, for closing and sealing cardboard boxes or like containers, of the kind in which the containers are carried to mechanism that glues the outside flaps and folds them on to the inner flaps, and then to a conveyer of the kind described in Specification 528,187, [Group XXX], which applies pressure to the closed flaps. According to the invention, controlling members are provided for keeping the flaps in their folded condition during the transfer of the containers to the conveyer, and means are provided for adjusting the members, simultaneously with the adjustment of the folding unit to suit containers of different sizes, so as to keep the distance between the controlling members and the conveyer constant. The containers 81, Fig. 1, are moved by pusher bars 12 on endless chains 11 beneath glueing apparatus 56, guide rails 52, and flap-folding ploughs 53 whence they are fed between conveyer belts 72, 73. The members 52 and 56 are carried by a frame 26 the height of which is adjustable by means of motor-driven screws 29, 31 to suit the height of the containers. The separation of the folders can be adjusted also by means of screws 41, 42 to suit the widths of the containers. Flap-controlling members are mounted on the guide rails 52, each member consisting of a series of flanged rollers 62, Figs. 1 and 3, freely rotatable on vertical studs on a supporting member 63 provided with a slot 64 for engagement with rollers 61 on the rails 52. Studs 68 on the supports 63 engage in an inclined slot 69 in a bracket 71 which is attached to the frame of the conveyer 72, 73, the slot being parallel with the inclined leading-edge of the conveyer belt 72. Thus, as the frame 26 is moved to adjust the height of the folding unit, the engagement of the studs 68 in the slots 69 causes the support 63 to move on the rollers 61, and the distance between the foremost flanged roller 62 and the inclined portion of the belt 72 remains constant. In the operation of the machine, the side flaps of the container are glued and are turned by the ploughs 53 on to the inner flaps which are held in their folded position during this operation by a guide 82 supported by the frame 26. During the further passage of the containers to the conveyer, a spring loaded central shoe 83 keeps the flaps in their folded position until the upper side edges of the container are engaged by the flanges of the rollers 62, as shown in Fig. 3. These maintain the folded condition of the flaps while the containers are being transferred to the conveyers 72, 73.

Abstract: 992,580. Semi-conductor devices. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Sept. 4, 1961 [Sept. 12, 1960; Dec. 9, 1960; June 13, 1961], Nos. 31335/60, 42424/60 and 21234/61. Heading H1K. The sealed housing of a semi-conductor device is formed by forcing a cup-shaped housing part, the rim of which is inclined with respect to the axis of the cup, into contact with a second housing part. The rim is forced inwardly or outwardly into engagement with an edge structure on the second part to form a seal therewith. In a typical assembly, Fig. 6, the rim 3 which is frusto-conical before assembly is forced flat by axial pressure to bite into the foot of the annular rim 4 of the base part. In alternative forms of this assembly the semi-conductor device 7 is mounted on a stud extending through the base part or on a metal plate placed within the rim of the base. As a further alternative the rim of the cup may be inclined inwardly and forced into edge engagement with a boss formed in the base. In this ease the channel formed between the side walls of the boss and cup may be filled with solder or plastic to reinforce the seal. In other arrangements (Figs. 9 and 11) the inclined part formed by cutting a groove in the rim is forced to bite into the outside surface of annular rim 18 (Fig. 9) or the wall of a circular recess 20 (Fig. 11) in the base by application of axial pressure. When a soft material is used for the base, rim 27 (Fig. 14) can be reinforced by inserting a ring 26 of hard metal into an annular groove formed outside the rim. In this case the axial pressure is used to flatten the frustoconical rim 3 of the cup and dig it into the rim.
