Abstract: ABSTRACT OF THE DISCLOSURE:         It is known to contact molten cast iron with various treating agents in the casting mold in order to influence the base structure or the form of the graphite.  Such casting molds for making castings of cast iron containing vermicular and/or spheroidal graphite are provided with an intermediate chamber, which is provided in the pouring system between the pouring gate and the ingate to the casting mold proper.  That intermediate chamber serves to receive the graphitizing agent and to contact it with the molten cast iron.  To permit a functional adaptation of the chamber surface area or the sur-face area of the treating agent contained in the chamber to the pouring rate, which changes as the pouring proceeds, the casting mold according to the present invention is provided with a frustopyramidal intermediate chamber which has a rec-tangular base disposed in the parting plane of the mold.

Abstract: A PATIENT TREATING MATTRESS                  ABSTRACT OF THE DISCLOSURE A disposable or reusable "crawl resistant" flexible mattress formed of panels sealed together to define alternately inflatable passages between the panels for sequentially altering supporting structure for a long term bed patient to reduce decubitus ulcers, bed sores, etc. The mattress has vent holes in its top for ventilating the patient with inflation gas and a crawl resistant layer bonded to a bottom of the mattress to prevent the mattress from "crawling" relative to the bed and patient during use. In one form of the mattress, crawling is reduced by a separation between the inflation passages so individual sections of the mattress can more readily conform to a patient's body contour.

Abstract: ABSTRACT OF THE DISCLOSURE        An improvement on prior art uses a card having a longi-tudinal strip of magnetic tape encoded with two separate tracks. One track contains a security code and data as to the number of uses remaining on the card.  The other track is a control having signals which are read directly proportional to the speed of movement of the card.  The card is inserted in a slot in a machine which feeds the card into the machine, reads the data on both tricks, reverses the direction of the card, and impacts the card with a hole to indicate that it has been used one time. The position of impact is controlled by the number of uses of the card prior to the particular use and the control track. While the card is traveling in the reverse direction the first track is re-recorded with the number of remaining uses and security code at a rate determined by the control track,  The invention overcomes a problem of prior systems resulting from factors interfering with precise speed of movement of the card, since the control track moves at 8 proportioned speed, the use of oscillators, clocks, phase locked loops and other timing devices is eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE    A finished product controller is disclosed for monitoring the performance of a glassware production line and the bottle inspection equipment operating thereon.  Bottles are formed in molds which impress an identifying code unique to each mold in each formed bottle. Bottles leaving the forming machine are fed to one of several inspection loops.  A primary inspection loop includes means for inspecting the bottles fed to it for defects and means for reading the identifying code on those bottles.  One or more secondary inspection loops are provided for inspecting the rest of the bottles for defects only.  A computer correlates the detected defects in the bottles passing through the primary inspection loop to the defective mold which produced them and acquires defect data on the secondary loops.  A cavity reject ratio is calculated for each defect and compared to a predetermin-ed value to alert a forming operator to a defective cavity.  The reject ratios are totaled for each defect and the ratio for each defect from each loop is compared to the corresponding ratio from the other loops -to identify malfunctioning inspection devices.          Located downstream of all of the inspection loops is a means for reading the identifying codes of all the inspected bottles.  In the alternative, the downstream reader can sense the presence of bottles formed in a particular mold which has been determined in the primary inspection loop to be defective, and the computer can alert maintenance personnel to locate and correct the defective inspection equipment in one of the secondary inspection loops.
