Title: Improvements in or relating to article wrapping machines
IPC: B65B27/08
Filed: 1964-03-06
Abstract: 1,034,161. Wrapping-machines. BROOKHIRST IGRANIC Ltd. March 6, 1964 [March 28, 1963], No. 9610/64. Heading B8C. Articles, such as newspapers in stacks, are supplied from a stacker 2 by means of a transfer unit 4 to a loader 6 where they are pressed downwards by a ram 16 on a wrapper sheet 14a, the wrapper ends are tucked into grippers 36a, Fig. 6, by blades 22 and the partially-compressed package is carried intermittently along a slide plate 46e past a gluing unit 48 and through a compression unit 40 by means of pairs of upper and lower conveyers 36, 42 respectively and an endless belt 40g. The grippers 36a are mounted on the conveyers 42. The height of a compress sion bed 46 is adjustable. By tripping a switch the transfer unit effects operation of the ram 16, a cam on which operates a further circuit to raise the ram; the tucker blades 22 are lowered, thereby forcing the wrapper ends into the grippers 36a. The blades 22 are raised in two stages. Brackets 42a on the lower pair. of conveyers 42 engage the stack SP as the drive to the conveyers 36, 42 and to the belt 40g is engaged. At the same time a pusher plate 38c is extended in order to skew the upper part of the stack, which compensates for subsequent deformation when the stack is again compressed. As the stack passes down a step 46g in the plate 46e, the drop in level of the plate causes the wrapper to tighten about the stack. A cam on the conveyer mechanism breaks a circuit to de-energize the conveyers and belt 40g. Further compression occurs, in the next cycle of the machine, under the action of rollers 40d and a cantilevered member 40c held down by a further pressure roller. The shape of the member 40c, Fig. 6, enables the upper surface of the stack, which is concave due to its folded edges, to be evenly compressed. The wrapper edges, released from grippers 36a, travel along guide plates 48f, 48b. Folding plates, overlying the member 40c, turn the wrapper ends in, the outer flap being in contact with a glue roller. The ram and tucker mechanism are operated through pneumatic cylinders.

Patent HK-112094-A (HK)
Title: Data storage apparatus
Inventor: CRONIN DAVID V
IPC: G11B5/596
Filed: 1994-10-12
Abstract: A magnetic data storage system for use with a double sided disk in which a prerecorded pattern of opaque optical lines is used to define the tracks in which magnetic data is to be stored. A separate optical system including an illumination source and a photosensitive detector is provided on a read/write assembly for each side of the disk. Each detector is designed also to serve as a reference grating. The illumination source is designed to image the prerecorded pattern of optical lines on the reference grating as an indication of the alignment of the read/write head of the assembly and a desired data track and any misalignment of the head and track generates a servo signal. The detector uses four separate photocells interleaved in a prescribed fashion to form a quadrature detector that is adjustable to compensate for various non-uniformities. One form of illumination source uses a surface-emitting light emitting diode and optics for forming a multiple beam source.
