Abstract: A tunnelling and lining machine has means mounted on it for lining the circular-section tunnel which it excavates with a helical winding of a flexible band, fed from a reel on the structure of the machine by an ejector following a circular path around the longitudinal center axis of the machine. Control of the speed of rotation of the ejector, and of its position along the longitudinal direction of the machine, are provided for so as to allow the turns of the helical winding to be applied at a desired constant relationship irrespective of the speed of excavation. Drive means for positioning the ejector longitudinally and for rotating it may be in common. The ejector expels the band by means of rollers some of which may have the function of giving the band which was flat when stored on the reel, a shaped cross-sectional profile. A reloading drive is provided for the reel.

Immediately below the base member, there is positioned a washer plate having a size sufficient to block the bore of the nozzle. Passing upwardly through the plate and extending into the space between the jaw members there is a threaded rod provided at its upper end with an enlarged head contacting the opposed inner faces of the jaw members. The lower end of the rod below the washer is threadedly engaged to a wing nut which is manually operated.

Abstract: Process for preparing hydratable, proteinaceous food products involving: subjecting moist (e.g., crumbly to free-flowing), hydratable, proteinaceous food material having suitable moisture to elevated mechanical pressure and suitable temperature and pH conditions to convert the protein material under non-puffing conditions to a dense, substantially homogeneous, translucent to glassy, coherent, bonded, proteinaceous product of desired size and shape. The material is thereby bonded together so as to be capable of withstanding the disruptive deterioration and loss of structural identity caused by subjecting the proteinaceous material to retorting conditions such as used in food processing. The translucent to glassy, proteinaceous product yields hydrated food products having structural integrity and desired textural characteristics.

Abstract: A seat is attached to the top of a vertically disposed trunnion member mounted for rotation about a vertical axis relative to a vertically disposed tubular intermediate member. The trunnion member and intermediate member are vertically adjustable together relative to a vertically disposed tubular base member. All three members are secured together into an assembly by a plurality of securing elements. The seat and trunnion member cannot be removed from the assembly without removing or disengaging a securing element. None of the detachably engaged securing elements are accessible. The only accessible securing element cannot be removed from a securing disposition without destruction thereof. This provides an effective mechanical and psychological deterrent against theft of the seat.
