Title: Textile processing - partic the shearing or roughening of textile sections, using a machine control mechanism actuated by
Inventor: CONRADS HANS
IPC: D06C13/00
Filed: 1972-01-20
Abstract: Control mechanism for a textile machine, partic. for the shearing or roughening of textile sections, is actuated by a seam sensor so as to engage or disengage, or lower and raise a machine part for processing the textile width. This is inactivated when a seam passes through, and the seam sensor emits preselectable impulses to a first counter so that when a predetermined number of pulses have been emitted, the machine part is switched off or disengaged. After lowering of the seam sensor the pulses are passed to a second counter which switches on or once again engages the machine part once a predetermined number of pulses have been generated. The number of pulses to both counters is regulated as a function of the speed of the textile material.

Title: Automatic pigs-head debristling machine - for conveyor line slaughter-house
Inventor: BAROZZINI GINO
IPC: A22B5/08
Filed: 1973-09-08
Abstract: A main frame within which a first subframe can traverse horizontally at the same speed as the carcases suspended head down from bogies on an overhead monorail has within that first sub-frame, a second which can be traversed vertically. This second subframe has mounted on its top a first pair of horizontal parallel shafts carrying multiple scraper arms and below them a second pair of shafts perpendicular to the first, also parallel, horizontal and carrying scraper arms. The passage of the carcase past a microswitch system upstream of the head debristling station triggers a programme timer which energises the electric drive motors for the reduction gearboxes whose output shafts carry drive pionions for the horizontal and vertical racks producing the desired tracking and rising motions for the frames and in such a way that the head of the carcase is guided into the first pair of scraper shafts which separate elastically in response to a sensor spring and then into the second pair of scraper shafts so that the head is debristled.

Title: Cartons forming plastic film packing - have tear-open strip welded so as to tear along seams when peeled off
Inventor: GOODE JEFFREY LEONARD
IPC: B65B61/18
Filed: 1973-09-28
Abstract: The packing has a tear-open strip joined to it by a butt seam along both edges. The tension strength of the strip in the lengthwise direction in relation to the tension strength of the material of the packing itself in a direction parallel to it, or the strength of the weld seams, is such that the packing tears along lines near the seams, or along the seams themselves, when a peeling force is applied to one end of the strip. The item can be packed by feeding it forward against a curtain formed by a strip of heat-shrinking plastic and one of tear-off material, pulled off opposite rolls and welded together, until the curtain encloses the item as far as its rear edge. The linear speed of the tear-off strip is no more than a quarter of that of the plastic, and the two strips are welded in the transverse direction behind the item and parted off, leaving a continuous curtain behind. The tube enclosing the item is then shrunk to size by heating.

Title: Support chain for flexible supply lines - has balls enclosed between neighbouring links to restrict relative angular motion
Inventor: KLEIN ERNST
IPC: F16G13/16
Filed: 1973-11-20
Abstract: To support supply llines such as hoses or cables between stationary supply points and mobile users, a flexible chain type element is used. The chain links are formed by oblong plates which have a number of recesses concentrically placed about the pivot centre on either end. Steel balls enclosed in the recesses of neighbouring chain links restrict the relative angular motion to a value of less than 30 deg. This enables the chain to form a self supporting loop which can be displaced along a straight line by rolling motion. The two sets of chain link plates are connected by bridge plates which are attached to opposite inner link plates. Holes in the bridge plates l ocate the supply lines in the central region of the support chain.
