Abstract: ABSTRACT OF THE DISCLOSURE     A clutch drum for an automatic transmission features a large diameter portion in which a plurality of first slots  define  castle-like  projections  or  crenelations about one end thereon and a second set of slots which originate in the projections near the tops thereof and which extend to and terminate in an essentially frustro-conical portion which interconnects the large diameter portion and a small diameter portion containing a piston therein.   The first slots serve to mount clutch discs within the drum while the second ones mount discs about the drum.   The relatively wide castle-like projections allow the production of the drum from relatively light gauge sheet metal, which has adequate structural rigidity and a reduced maximum diameter.

Abstract: CONTINUOUS LOADING APPARATUS AND METHOD     ABSTRACT OF THE DISCLOSURE   Loading apparatus particularly for mucking operations in confined space The apparatus includes primary and secondary conveyors disposed in tandem about a longitudinal axis so that a rear portion of the primary conveyor is above the forward portion of the secondary conveyor. The primary conveyor can extend axially forwardly from the secondary con-veyor assembly and has a penetrator mounted adjacent the forward portion thereof, the penetrator being adapted to be oscillated, automatically if desired in several modes dependent on loading conditions, to facilitate loading of material onto the primary conveyor as the primary conveyor is extended. The apparatus has a supporting body which carries the secondary conveyor and forms a rigid supporting structure which is carried on adjustable legs to restrain the apparatus against mucking loads and to enable the apparatus to be set in a desired attitude so that the penetrator follows a pre-selected path or plane, irrespective of inclination or roughness of ground supporting the apparatus or resilience of apparatus suspension. The apparatus further can be restrained against movement by extendable rams which extend upwardly and/or laterally from the apparatus to engage adjacent rock surfaces, if available, so as to augment restraint o-f legs. When operating, as loading conditions become more difficult, frequency of oscillation of the penetrator can be decreased whilst amplitude increases. In more difficult conditions, the penetrator is raised progressively to reduce load on the penetrator, and the penetrator can he subjected to two oscillations having different frequencies and amplitudes.

Abstract: ABSTRACT OF THE DISCLOSURE      A method and apparatuses for expressing the liquid phase from a wet mixture such as a clay-like mixture include a primary roll (12, 104) with a plurality of smaller pressure rolls (13, 112-118) biased against its surface at circumferentially spaced intervals and at increasing pressures.  The primary roll and at least the upstream one (112) of the pressure rolls have a thick outer covering of a substantially deformable elastomeric material.  A pair of opposed filter belts (22, 23 or 142, 144) are trained about the primary roll and means are provided to feed the wet mixture between the belts to carry the mixture successively through the nips between the primary roll and the pressure rolls.  The mixture is initially sub-jected in the first nip to a relatively gradual rate of increase in pressure and in subsequent nips is subjected to progressively steeper rates of increase in pressure adapted to the different flow behavior of the mixture caused by the increasing solids content of the mixture.          In one embodiment all of the pressure rolls (112-118) are covered with equally thick elastomeric layers of equal hardness, and the first roll (112) is biased with a pre-determined relatively low pressure to initially subject the wet mixture to said relatively gradual increase in pressure. In an alternative embodiment intended for wetter mixtures, the rolls (112'-118') are covered with equally thick layers which increase in hardness in the direction of travel of the belts.  Specially fabricated belts and edge seals are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to an improved hot tip nozzle seal for use in a sprue gated injection molding system and a method of manufacture.  The nozzle seal has a cylindrical outer portion, an elongated central pin portion and a number of ribs extending therebetween to define a number of apertures through the nozzle seal.  The outer portion is seated in both the heated nozzle and the cavity plate to bridge the insulative air gap between them.  As well as preventing the melt flowing into the air gap, this locates the heated nozzle relative to the cavity plate and accurately locates the pin portion in the center of the gate.  The melt passage extends through the heated nozzle bore, through the apertures in the seal and through the gate into the cavity.  The central pin portion of the seal has a tip portion which extends downstream into the gate and a head portion which extends upstream into the nozzle bore.  The central pin portion has an inner conductive portion formed of copper and an outer protective casing formed of steel.  The seal is designed so that the head portion picks up a predetermined amount of heat from the surrounding melt and transfers it through the highly conductive copper to the tip portion which extends to where it is required, without being unacceptably susceptible to abrasion or corrosion from difficult materials such as glass filled flame retardant nylon.          The seal is made by integrally filling the steel pin casing with copper in a vacuum furnace.  The filled casing is then brazed into a body portion with the ribs and a cap brazed on in the vacuum furnace to provide the integral abrasion and corrosion resistant nozzle seal.

Abstract: ABSTRACT       The invention relates to a method and an arrangement for measuring and controlling the thickness of optically effective and, particularly, transparent coatings during their build-up on substrates in vacuum coating installations.  The measurement is carried out by determining at least one reference value and at least one measured value for the transmission or reflection value of the coated object by using a measuring light beam, a monochromator, a photo-receiver, an amplifier and an analyzing circuit.     According to the invention and for the purpose of solving the problem of enabling the measurement and display of absolute values to be carried out in the case of any required thicknesses of coating, an adjustable amplifier having an extremely linear characteristic curve is used, a first reference value is formed and stored, the degree of amplification is increased until the first reference value reaches a maximum, whereupon both the first reference value as well as the associated degree of amplification are likewise stored, a further reference value is formed, which is at a considerable distance from the first reference value and is amplified to the same degree as is the first reference value, and the actual value is then measured and is multiplied in a computer unit by the degree of amplification and is represented in dependence upon the wavelength.

Abstract: ABSTRACT         An interlocking system comprising a plurality, e.g., three, of parallel sub-systems operating asynchronously to produce identical replicated outputs which are mutually compared to deter-mine the correct output and disqualifying a minority output thereby ensuring high system integrity.  Each sub-system includes a similar arrangement for computing the difference between all possible pairs of sub-systems.  Comparison of these results with a reference table of all possible difference results and then comparison of the difference equations yields a common factor which is the sub-system producing the error.  Action can then be taken to disqualify its output, e.g., by switching-off its power supply.  A final output is taken, preferably from one sub-system, with a second as standby.  To accommodate asynchronous running, a final output is only acted upon if it is repeated in a succeeding output cycle thus permitting opportunity to disqualify the preferred output if it is judged in error by the other sub-systems and to replace it by the standby.

Abstract: PROCESS FOR IMPROVING ELECTRODE COATINGS            Abstract Disclosed is a method of improving the coating on electrodes in spark gap devices which minimizes filament formation densifies the coating, and ensures a good bond between the coating and underlying electrode.  The device is coupled to a circuit which includes appropriate components so that a rapid sequence of current pulses having large amplitudes during arc initiation is passed through the device.  The coating bonds with a different area of the cathode for each current pulse.  The signal may be applied with appropriate reversal of polarities so that essentially the entire surface of both electrodes is thus reacted.  Subsequently, the device may be subjected to an additional pulse in order to leave asperities on the surface which will increase field emission and ensure a low surge limiting voltage.

Abstract: ABSTRACT OF THE INVENTION           A novel balloon catheter apparatus for treatment of atherosclerotic occlusions within the cardiovascular system, comprising a catheter defining a through-going lumen, a fluid supply syringe attached to one end of the catheter for supplying fluid through the lumen, and a balloon attached to the other end of the catheter which is inflatable by forcing fluid through the lumen.  A pulse generator is also attached to the catheter for generating pressure pulses in the fluid through the lumen, which pulses cause the balloon to sharply expand and contract at intervals.  The pulse generator includes a pulse syringe communicating with the lumen, a spring-driven ram to contact the piston of the pulse syringe, and a cam rotor to move the ram away from the piston, thereby compressing the spring until the cam rotates further and the ram is released to strike the piston.  When the balloon catheter is inserted in the cardiovascular system of the patient and guided to the occlusive site, the balloon is first inflated by the supply syringe until the balloon contacts the occlusive material, and then one or more pulses may be applied by the pulse generator through the fluid to rapidly expand and contract the balloon.  Since the occlusive material is much more brittle than the surrounding wall, the wall expands in response to the pressure pulses while the occlusive material cracks and separates from the wall to be removed through normal cardiovascular processes.

Abstract: ABSTRACT OF DISCLOSURE            The sputter  deposition of a thin film of material on both sides of a thin substrate is performed by positioning the substrate sides orthogonal to the target and preferably radial to the deposition center of the sputter system. The vapor deposition of alumina on a this ferrite core for a magnetic head is accomplished by positioning the ferrite substrate in the vacuum chamber orthogonally to the target and radial to the particle deposition center. The alumina is deposited on both sides of the ferrite core simultaneous1y to substantially the same thickness. The deposition on both sides of the ferrite core protects the core against width erosion, and minimizes bending stress.  In addition, signal output of the ferrite core when used in a magnetic head is increased.
