Abstract: A stamp for forming an impression into hardenable material and an elongate body carried by the stamp for movement between retracted and extended conditions for measuring the distance between impressions.

Abstract: A machine for compacting and moulding concrete mix or other plastic materials comprises, in combination:(a) a body structure;(b) a tunnel shaped moulding member having a top and two sides and open at its bottom, the moulding member being attached to the body section;(c) an opening in the top of the moulding member adjacent to the body section;(d) a hopper adapted to carry concrete mix or other plastic materials, and feed the mix or materials to the opening, the hopper being attached to the body structure;(e) a substantially vertical ram plate having a shape which corresponds to the cross-sectional shape of the moulding member, the ram plate being located within the moulding member and being adapted to move reciprocally from a first position adjacent to the body structure to a second position wholly within the moulding member, without oscillation of the ram plate;(f) means to cause the reciprocal movement of the ram plate, the means being carried by the body structure, and(g) means supporting the body structur
