Title: Apparatus for stopping a travelling wave loom upon its weft thread carriers having encountered an obstacle in the shed
IPC: D03D51/18
Filed: 1974-10-22
Abstract: An apparatus for stopping a travelling-wave loom when its weft thread carriers encounter an obstacle in the shed, includes a drive and a control circuit of the drive, a weft thread carrier guideway, and a lining made of a conductive pile material. The guideway arranged in the shed is connected to one of the poles of the control circuit power supply, the opposite pole of the power supply being connected to the lining made of the conductive pile material. This lining being located outside the shed, the piles thereof pass between the warp threads and are permanently electrically connected to the electric contacts of the carriers. The electric contacts are pivotally mounted within the carrier and, as the latter engages an obstacle in the shed, they protrude therefrom to come in contact with the guideway to thus close the electric control circuit and bring the loom to a stop.
Patent ES-432889-A1 (ES)
Title: Device for severing and feeding flaccid wrapping sheets
IPC: B65B41/16
Filed: 1974-12-13
Abstract: A device for feeding wrapping material of flaccid type for use in a wrapping machine. Initially an elongate strip of the flaccid material is moved forward, and is only partly transversely cut to define sheets which can thereafter be torn from the strip. The sheets are left under control, as to their exact positions, until they are taken by the wrapping mechanism, along with the product to be wrapped. For this purpose the partly cut strip of flaccid wrapping material is guided and moved forward by rolls and guides which impress longitudinal strengthening ribs in the material. The strip is then engaged by sheet tearing and flattening rolls which have aligned, cylindrical surface portions rotating at a speed greater than that of the moving strip itself to detach successive sheets from the partly cut strip and to control each detached sheet as to its position until it is engaged with the product to be wrapped in it.

Title: Door control device with closure regulator
IPC: F25C5/00
Filed: 1976-12-23
Abstract: A device for controlling the opening and closing movement of a duct seal door of an automatic ice maker which requires a regulator for slowing down the closing of the door. The movement of the door about its rotational axis is transmitted via connecting linkages to the closure regulator which comprises a rotor positioned within a stator housing. The rotor's movement is coupled to the connecting linkages via a one-way clutch which decouples the rotor when the door is being opened, and causes positive coupling therebetween when the door is being closed. Disposed within the stator housing in a fixed-volume compartment is a viscous fluid, such as silicone gum. The rotor and stator include opposed rippled surfaces between which the viscous fluid is coactively disposed. The fluid acts as an impedance to the motion of the rotor, which motion occurs only upon the closing of the door, to thereby provide a controlled slow closure thereof.
