Patent ES-358273-A1 (ES)
Title: Combing machine
IPC: D01G19/14
Filed: 1968-09-18
Abstract: A detaching cylinder 1 of a combing machine is carried by a support 1a driven with an alternating movement perpendicular to the axis of the cylinder in the directions F and is driven with an unsymmetrical oscillating rotational movement, having an amplitude A 1 in the delivery direction greater than the amplitude A 2 in the opposite direction. The oscillating rotational movement of the detaching cylinder 1 is derived from a helical pinion 2, coupled in rotation with the cylinder 1, which is rotated by its constant contact with a cylindrical control rack 4 whose axis is orthogonal to that of the pinion. The rack 4 has simultaneously imparted thereto by two control devices CR and CT a rotational movement and a reciprocatory, axial, linear movement. Control device CT, which may be hydraulic, electric or mechanical (as shown) imposes on the rack a reciprocating movement whose amplitude is such that the corresponding theoretical rotational movement of the detaching cylinder (i.e. the movement it would undergo if subjected solely to this control) is a symmetrical oscillating movement having an amplitude equal to (A 1 + A 2 ). The control CR im- 2 poses on the rack a movement of continuous rotation whose direction corresponds to the delivery rotational direction of the detaching cylinder and whose angular speed is such that the corresponding theoretical movement of the detaching cylinder is a movement of continuous rotation which, during a time lapse equal to the duration of a single linear stroke of the rack (in either direction), has an amplitude of (A 1 -A 2 ) / 2. The two controls may be actuated from a common drive shaft 5. The linear control CT consisting of an eccentric plate 7 fixed to the shaft 5 and coupled via a rod 8 to a slider 9 mounted on a shaft 10, the slider also being rigid with an axial thrust bearing 11 in which the rack can rotate. The amplitude of the stroke is regulated by movably housing the rod end in a slot 12 of the plate. The rotational control CR comprises a toothed cylinder 17, meshing with a pinion on the rack, driven by a transmission gearing 13, 14 from the shaft 5.

Title: Chemical package
IPC: B01L3/00
Filed: 1968-12-24
Abstract: A disposable reaction container has a lower section 12 with one or more separate lower compartments 24, 26 and an upper storage section 14 having a plurality of reagent storage chambers, e.g. 20, for each compartment. Each storage chamber has at least one deformable longitudinal rib R for holding one or more reagent tablets T in place, until the application of force to the top of a chamber causes inversion of the top-hat configuration of the latter and the deposition of the tablet in a lower compartment 24, 26. Flanges 38 and 44, encircling the perimeters of the lower and upper sections respectively, are of equal size enabling the two sections to be heat sealed together to provide a unitary disposable container when these members are formed from a plastic material. The flanges have an extended portion which may be used to carry a code area. The container may have rigid walls, or, to assist in the optical analysis of a sample injected therein, the walls may be flexible, with one pair at least being transparent. In a further embodiment, each storage chamber has a reversed taper (see Fig. 5) for more secure storage.
