Patent CA-1075358-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a rotary head assembly, for example, a rotary head assembly for recording or reproducing video signals on a recording tape wrapped at least partially around the tape guide drum of a video tape recorder.  The head assembly includes a primary support, an intermediate support and a recording and/or reproducing head.  The primary support is moved in a circular path concentric with the guide drum.  The intermediate support is connected to the primary support by a first spring which yieldably resists centrifugal movement of the intermediate support relative to the primary support.  The recording and/or reproducing head is connected to the intermediate support by a second spring which provides the head with a natural frequency of movement relative to the intermediate support.  This natural frequency of movement is substantially greater than the natural frequency of the centrifugal movement of the intermediate support relative to the primary support.  As a result the rotation of the primary support at operating speed causes the intermediate support to move against the bias of the first spring so as to place the head against the tape, while *he head can move rapidly relative to the intermediate support so as to follow high frequency vibration of the tape and to reduce hunching of the tape at the locations where the head first contact it.

Abstract: Abstract of the Disclosure The present invention relates to the production and chemical treatment of sodium and/or potassium hydrosilicate glasses containing about 5-50% by weight water within the glass structure, wherein the Na+ and/or K+ ions are capable of being partially completely replaced, on an electro-lytically equivalent basis, by protons and/or other monovalent and polyvalent cations species, to make glass articles whose alkali metal oxide content is substantially diminished or completely removed.  Such glass articles can be either completely dense, or microporous, with pores ranging down to molecular size.  Moreover, the chemical compositions of such microporous glasses can be further altered to include many other chemical species including polyvalent cations, anions and neutral molecular species, both organic and inorganic, and including complex ions such as metal amine complexes, where such species are capable of being sorbed on the porous glass by physical or chemical forces or both. The instant invention provides means for replacing part or all of the Na+ and/or K+ ions in an alkali silicate hydrosilicate amorphous body either with protons, or with protons plus other monovalent or polyvalent cations, in the nondestructive manner by reaction in aqueous solutions.  In addition, it provides means for incorporating many other chemical species into the ion-exchange microporous body at low temperature, by sorption from solutions, either aqueous or nonaqueous.  These latter species are not necessarily cations.  The processes of the invention make possible the alteration of the chemical composition of alkali hydrosilicate body to any of a wide variety of other glass compositions having better chemical durability and other useful glass properties.

Abstract: ABSTRACT An apparatus and method of assisting the driving of a hollow pile into soil by electro-osmosis in which electri-cal direct current is directed downwardly through the inside of the pile, out the bottom of the pile, and up the outside of the pile whereby water on the inside of the pile moves through the soil whereby making the pile easier to drive into the soil.  The method includes insulating an electrically conductive pile preferably on the inside with an electrical non-conductor and placing water inside of the hollow pile. An electrical circuit having a d-c power source, and an anode and cathode is provided in which the anode is placed in the water inside of the hollow pile and the cathode is placed outside of the hollow pile and in electrical communica-tion with the outside of the electrical conductive pile whereby an electrical circuit is formed between the anode and cathode through the water in the inside of the pile and through the bottom of the pile.  When electrical power is supplied to the circuit, water will move down the inside of the pile and up the outside of the pile and into the soil adjacent the pile making the pile easier to drive through the soil.  In addition, after the pile has teen driven, the current flow may be reversed through the electrical circuit for reducing the water content of the soil adjacent the pile thereby increasing the load bearing strength of the soil.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention provides an improved process for mass polymerizing a solution comprising a monoalkenyl aromatic monomer having a diene rubber dissolved therein.  The improve-ment comprises dissolving a minor amount of an aliphatic mono-olefinic compound in the solution, and then mass polymeriz-ing the solution at temperatures of from about 80-180°C, with agitation.  Polymer molecules of the monomers are then formed as a matrix phase having a diene rubber dispersed therein as rubber particles grafted with and having occluded at least a portion of the polymer molecules.  The olefin compound is selected such that during polymerization, the olefinic compound forms free radicals with the monoalkenyl aromatic monomer that are more active than a monoalkenyl aromatic free radical in chain transfer with the rubber increasing the grafting of the rubber with the polymer molecules.  The improved process of this invention increases the grafting of the rubber phase yet allows the matrix phase polymers to reach optimum molecular weights consistent with optimum physical properties.

Abstract: ABSTRACT A clock cycle is provided by a delay device, the output of which is coupled via an inverter to the input thereof, which inverter is combined in a gate structure so as to enable such clock cycle and derivative clock pulses coupled to be generated as a signal passes through the delay device. The gate structure is coupled to receive a so-called stall signal in-hibiting the clock system from generating an output.  The stall signal so inhibits such clock system only after the present clock cycle is completed.  Further, the gate structure is coupled so that a stall signal received and then cleared before the end of the clock cycle will have no effect on the system.  The system also responds to a removal or clearing of a stall signal by immediately beginning another clock cycle after the relatively insignificant delay introduced by the gate structure.

Abstract: ABSTRACT OF THE DISCLOSURE         A machine and method is disclosed for forming, tensioning and sealing a strap loop about  a package and then severing the sealed loop from the trailing length of strap.  A small primary strap loop is formed by feeding a free end of a length of strap into a circular cup through a slot in the cup sidewall so that the free end is guided by the inner periphery of the cup to form a loop with the strap free end overlapping a portion of the loop.  The cup is movable from an upper position around the formed primary loop to a position out of contact with, and below, the loop.  A cylindrical gripper is provided inside the loop and a smooth-surfaced anvil is provided on the exterior of the loop for engaging the overlapped portion of the loop therebetween so that the strap free end is restrained by the gripper while the overlapped portion of the loop can be continued to be fed to expand the loop to a larger predetermined diameter.  The strap free end remains restrained by the gripper as the strap is tensioned to tighten the loop about the package.  The grip-per is then rotatably oscillated at a high frequency to cause the strap free end to slide against the overlapped portion of the loop thereby generating heat and fusing the strap free end to the overlapped portion of the strap loop.  A cutter is provided to sever the tightened and fused loop from the standing length of strap.
