Title: Clutch assembly for an automotive vehicle
IPC: F16D23/14
Filed: 1968-02-29
Abstract: A diaphragm spring type clutch has the outer periphery of the spring 40 reacting against a clutch cover 20, an intermediate part bearing against a rib 46 of a presser plate, and the inner periphery engaged in a groove 56 of the outer race 58 of a clutch release bearing which is shifted to the left to disengage the clutch. The presser plate is connected to the cover 20 by tangential spring straps. The cover is secured by bolts 22 to a flywheel 16, and when the cover is detached from the flywheel the displacement of the presser plate under the action of the diaphragm spring is limited by the heads of bolts which are secured to the cover and pass through clearance holes in the presser plate. The limiting position is such that the inner periphery of the diaphragm spring remains engaged in the groove of the release bearing. Other forms of stop memher may be used to limit the movement of the presser plate. Assembly of the clutch, particularly is space is restricted, is thereby facilitated as the cover, presser plate, diaphragm spring and release bearing are fitted as a unit.

Title: Method and apparatus for automatically controlling the rate of flux injection to a converter
IPC: C21C5/34
Filed: 1974-03-27
Abstract: Flux is injected into the oxygen stream being fed to the tuyeres of a steel-refining converter, such as a Q-BOP converter or the like, and the rate of injection is controlled by varying the size of the outlet orifice of the flux-containing tank. The tank is pressurized to the same pressure as the oxygen stream into which the flux is being injected. The weight of flux in the tank is continuously measured and the actual weight is compared with a preset reference weight for each point in time. The difference between the two weights is used to drive a motor in either the forward or reverse direction to open or close the variable-orifice flux tank outlet valve an amount sufficient to adjust the actual injection rate to match the reference weight for a given time.

Patent ES-442432-A1 (ES)
Title: Electrical fault indicator
IPC: G06F11/30
Filed: 1975-11-07
Abstract: A method and apparatus for indicating a malfunction in the normal operation and operating components of electrical apparatus. A predetermined coded output is generated periodically in response to the proper operation of the apparatus being monitored. The coded output is conveyed to a decoder network which deciphers the input signal and provides a symbolic output for identifying the reception of the coded output. A timer operable to sequence through a predetermined time interval generates an output during the interval which is reinitiated in response to the symbolic output of the decoder network. In addition, means are provided for supplying a fault output, which is inhibited during the interval of the timer output. The timer interval is desirably selected to be greater than the interval between generation of the coded output so that a fault output is inhibited so long as the apparatus is properly operating. If for any reason, the decoder network fails to identify the reception of the coded output within the timer interval a fault output signal is conveyed representative of a malfunction in the monitored apparatus.

Title: Brightening of natural calcitic ores
IPC: C09C1/02
Filed: 1976-04-10
Abstract: A method for brightening a natural calcitic ore by removal of discoloring contaminants. The ore is crushed and formed into an aqueous slurry, which slurry is then coarse-milled to produce a product wherein no more than 1 percent of the particulate matter is +325 mesh. This coarse-milled product is then subjected to a further, wet-milling step, to alter the particulate such that at least 70 percent of the particles are less than 2 microns, thereby liberating substantial quantities of the discoloring contaminants. The liberated impurities are thereupon separated from the slurry by flotation and/or by subjecting the slurry to a high intensity magnetic field.

Title: Electronic combination lock and system
IPC: E05B49/02
Filed: 1976-09-16
Abstract: A unitary self-contained electronic combination lock is provided which includes a dead bolt manually operable from one side and operable from the other side only in response to insertion of a data combination card carrying a unique binary code in the form of selectively positioned metallic spots. Sensors located within the unit generate a binary 1 or 0 signal in response to the presence or absence of a metallic spot adjacent each sensor. The lock combination code is automatically changed to the data card's code upon insertion of a card having a code combination which includes part of the lock's code so that the previously issued cards will no longer operate to unlock the door. In this manner, the authorized code for each lock unit is automatically and independently changed to render inoperative all previously issued data cards.
