Abstract: Process for stabilizing cement stone, formed with binders rich in aluminates by setting with water, against high elevated temperatures and high humidity which comprises adding calcium sulfite to the aluminous binder material prior to setting. In another embodiment of the invention the addition of calcium borate along with the calcium sulfite provided even greater stability both initially and over a period of time. Calcium sulfite formed as a by-product of the waste gas purification of furnaces is the main source of supply for purposes of this invention.

Abstract: A sterilizable package having a plastic member marginally heat sealed to a paper member to which is applied indicia that changes color upon sterilization (gas and/or steam) on the inside of the package. The indicia is located in or near the marginal heat seal and is segregated from the package interior to prevent the package contents from covering or being contaminated by coming in contact with the indicia by heat sealing the plastic member to the paper member in the area of the indicia. The indicia can be located within the area covered by the marginal heat seal or within an unsealed area in the area covered by the marginal heat seal. The indicia can also be located interiorly of the marginal heat seal for example at a corner or angle formed between adjacent seals with the plastic member being heat sealed to the paper member in the area surrounding the indicia.

Abstract: A bottle labeling machine is provided with a circular rotatable support about which there are positioned a gluing station, a magazine carrying a stack of labels and a gripper cylinder so that the pickup-transfer surface of a segment carried by said support successively receives glue, picks up a label and transfers it to the gripper cylinder. The segment is geared so that while carried by said support it rotates about its own axis in opposite direction from the support and from the gripper cylinder. This permits a particular machine capacity to be realized with fewer gluing segments.
