Title: Automatic pack-forming and pack-cartoning
Inventor: CLARKE FRANK PERCY
IPC: B65B5/02
Filed: 1982-08-18
Abstract: A succession of products is cartoned by collating them into a pack of desired form, surrounding the pack with a cage c, folding up, a carton blank a closely around the pack-holding cage by passing the cage through a preformed folding box b, and withdrawing the formed carton from the cage (or the cage from the carton) to deposit the pack within the carton without substantially altering the pack form. The box is so sized and shaped that its side walls embrace the fold lines to form the carton automatically around the cage, and the blank-engaging edges of the mouth of the box are rounded to "lead in" the blank. <IMAGE>
Patent GB-2111100-A (GB)
Title: Implement assembly with pivot connection
Inventor: ASAL JERROLD R
IPC: E02F3/76
Filed: 1981-04-27
Abstract: An implement assembly (12) includes an implement (16), such as a blade (22) of a work vehicle (10), connected to a frame (14) through a pivot connection (23) for pivotally supporting the blade (22). The blade (22) and frame (14) are closely positioned to the front of the work vehicle for maximum stability and balance of the vehicle (10). A first apparatus (18) tilts the blade (22) generally vertically and a second apparatus (20), such as fluid cylinders (40, 42), moves the blade (22) to selected angular positions relative to the vehicle (10). The pivotal connection (23) has first, second, and third pivot axes (127, 129, 131) which allows the blade (22) to tilt and angle in various combinations without binding of the blade (22). A subframe (50) is pivotally connected to the frame (14) and to the second apparatus (20). The blade (22) moves along the subframe (50) during tilting, and with the subframe (50) during angling. The subframe (50) substantially eliminates lateral movement of the fluid cylinders (40, 42) during angling of the blade (22) and provides for mounting of the blade (22) and frame (14) close to the front of the work vehicle (10).

Patent GB-2135464-A (GB)
Title: Triplicate signal check circuit
Inventor: HINER PETER JAMES
IPC: G01R31/28
Filed: 1983-02-19
Abstract: Signals including the clock pulses, for an electronic system, such as an electronically-controlled telephone exchange, must be highly secure. Hence it is usual to provide three (or even in some cases more than three) nominally identical signal sources with checks between the outputs therefrom to find faults where such exist. In the present arrangement there are three levels of such signal sources, in the arrangement described clock pulse generators, with one fault detection circuit (FD1, FD2, FD3) per level. Each fault detection circuit (e.g. FD1) has a comparator (C1) which compares the pulses from the other two pulse generation levels. This comparator gives an output per discrepancy, which sets a fault latch (FL1) via a fault filter (FF1) which only passes an output to the latch after a preset number of faults. This avoids false alarms due to transient faults, but can be dispensed with if this facility is not needed. The outputs of the fault detection circuits are passed to an alarm unit which determines from the inputs it receives from the fault detection circuits which pulse generation circuit is faulty. <IMAGE>

Title: Ethylene Copolymers for Low Viscosity Hot Melt Systems
Inventor: ALIANI GIORGIO
IPC: C09J123/08
Filed: 1983-04-09
Abstract: Ethylene-vinyl acetate copolymers having a melt index of 1000 to 10000 and containing from 1 to 11% vinyl acetate are useful in low viscosity hot melt compositions, preferably in wax-free binary compositions with natural or synthetic resin tackifiers. The adhesives show long open times with short setting times, and low viscosity making them particularly suitable for high speed sealing operations such as packaging and labelling. In certain sealing applications the melt index of the copolymer may be as low as 600. The EVAs can be prepared by a high pressure polymerization, preferably by using chain transfer agent such as isobutylene to achieve high melt indices.

Title: Bend limiter
Inventor: JENKINS PETER DAVID
IPC: G02B6/44
Filed: 1985-10-14
Abstract: A bend limiter, which can also be used to carry tensile load without undergoing extension, comprises a tube whose wall has the form of a bellows in that it has alternating flared and wasted portions. The diameter of each flared and each waisted portion is fixed but the portions are free to move relative to one another to a limited extent, in a direction perpendicular to the axis of the tube. The latter freedom of movement allows the tube to bend but the fixed diameters prevent elongation. In one embodiment the wall is constructed out of a plurality of springs 1 which are mounted on circular hoops 2 so as to lie parallel to one another. The circular hoops 2 are of alternating size along the tube and provide the fixed diameters of its flared and waisted portions. The bend limiter finds particular application in the field of optical fibre submarine cables. <IMAGE>

Title: Shape parametrisation
Inventor: LEAVERS VIOLET FRANCES
IPC: G06V10/48
Filed: 1986-09-18
Abstract: Digital image data is transformed from an image space into a parametric transform space. Each point Pi is transformed to a sine curve Ci representing the angles ( theta ) and radii (r) of the normals to all possible lines passing through the point Pi. Straight line segments (P1 to P3) in the image space are detected by convolving the transform space with a mask which detects butterfly-shaped distributions of data around maxima (I) in the transform space. Curved segments in the image space are detected by convolving with two masks which detect pairs of ridges at the edges of belts of data in the transform space. The basic parameters of the segments can be determined from the locations of the maxima or belt edges in the transform space and can be efficiently stored or can be compared with a library of stored data. <IMAGE>
