Abstract: Systems and methods are directed to a compression scheme for stable universally unique identities in a collaborative editing environment. A client receives edits to a document and immediately creates a local short identity for an element of each edit, whereby the local short identity represents an offset from a base unique identity associated with the client from which a unique identifier assigned to the element is derivable. The local short identity information including the local short identity for each element is transmitted to a server. Subsequently, global short identity information is received from the server from which one or more global short identities that each map to a local short identity of a client of a plurality of clients collaborating on the document can be determined by the client. Each global short identity is a compact identity that is universally unique to the plurality of clients including the client.

Abstract: The present invention is a computer control system for a glass factory having a plurality of individual section glassware forming machines. The glass factory control system preferably comprises four microprocessor systems, respectively responsible for overall factory control, overall shop control, individual shop control and individual section control. At the most general level, a microprocessor called the factory supervisory computer performs such functions as scheduling jobs, controlling inventory, forecasting sales, determining fuel availability and cost, performing IS machine simulation and providing maintenance information. At the next level, another microprocessor called the console computer stores and manages all job history files, provides shop status information on demand and collects selected production data. Each shop computer performs such functions as controlling a stacker motor, monitoring temperatures, storing section status information and storing job timing information in nonvolatile storage.

Abstract: A method and apparatus for controlling the rate of operation of a glassware forming system including a temperature sensing device positioned in the blank and blow molds of an I.S. machine. The mean temperature over a period of time is derived for each of the molds. The mean temperature is compared to a predetermined optimum temperature. The optimum temperature is chosen to be the highest desirable temperature at which the corresponding molds should operate. In response to the comparison of the detected and optimum temperatures, the speed of the I.S. machine is varied to increase or decrease machine speed depending upon which the mean mold temperature is, greater than or less than the optimum temperature, respectively. However, before the speed is changed, if the detected and mean mold temperatures are greater than the optimum temperature, the amount of cooling air is increased until it reaches a maximum.

Abstract: A leakage analyzer method and apparatus for detecting faults in hollow structures such as polypropylene tubing and the like. The apparatus includes a hollow elongated test chamber through which the tubing is passed. At the outlet end of the chamber, a rear stop member prevents the tubing from passing completely through the test chamber as it is being fed thereto. When the trailing edge of the tubing passes a predetermined point, a rear stop member positions the structure in said chamber so that clamping means positioned at both the front and rear of the test chamber can be energized to clamp about the tubing and at the same time seal the respective ends of the test chamber. Plug members are positioned in the respective ends of the tubing and are expanded to seal the ends of the structure. A fluid such as air is introduced into the chamber and about the outside periphery of the tubing until the pressure in the chamber reaches a predetermined level.

Abstract: A system is disclosed for determining the mass of a moving molten glass gob. The gob is directed along a curved channel having a force measuring device over which the gob passes for measuring the force exerted by the gob normal to its path. The velocity of the gob is determined both before and after the normal force is measured by means of two sets of two position sensors, one set located on each side of the force measuring device, and a timer which determines the time period for the gob to move between the position sensors of each set. The timer also determines the time between velocity measurements. The data is used to calculate a value of acceleration which is substantially proportional to the acceleration normal to the path. The acceleration value and the output of the force measuring device are then interrelated in order to calculate the mass of the gob.

Abstract: A programmable automatic controller for operating machines having a plurality of components which operate in a timed or sequential relationship with one another. The controller includes a timing means for generating cycle clock pulses in synchronism with the operation of the machine, wherein the cycle clock pulses provide an instantaneous indication of the time elapsed in each cycle of operation of the machine. A COS/MOS running storage means stores the relative times during each cycle of machine operation when each of the plurality of machine components are to be enabled and/or inhibited. When the time elapsed in a cycle corresponds to a component actuating time stored in the running storage, an actuating signal is generated by a comparator. This signal is coupled to a machine component addressing arrangement which provides a component enable or inhibit command signal to the addressed component whose actuating time compared to the cycle time lapsed.
