Abstract: Abstract Elevator Car Vibration Control With Friction Damper In an elevator, a crossbeam or crosshead extends across the top of the car and a thimble rod extends through this beam.  The car is suspended on a spring which surrounds the rod and that is located on one side of the beam.  Located on the other side of the beam is a block assembly which grasps the rod and a vertical pin that is attached to the beam, for the purpose of providing dampening to the car.  A characteristic of this block assembly is that it allows some lost motion, during which there is no dampening, and this has, as an effect, extremely effective noise isolation between the rope and the car, but at the same time substantial dampening - for larger, more undesirable motions by the car.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and device for the casting of concrete products having one or several cavities,  involves passing a concrete mix around a cross-sectionally lobed cavity mandrel to form the cavities.  The concrete mix is compacted by rotating the cavity mandrel back and forth around its longitudinal axis.  The method may apply to a periodic or continuous slide casting method of production, and, by means of the non-circular cross section of the cavity mandrel, allows better compaction of the concrete mix below and between mandrels.  Prior compacting systems either failed to address the problem of non-compaction beneath the mandrel or attempted  to  solve  it by recourse  to noisy  and  thus undesirable vibrators.

Abstract: TITLE: METHOD AND APPARATUS HAVING RF        BIASING FOR SAMPLING A PLASMA INTO A VACUUM CHAMBER     ABSTRACT OF THE DISCLOSURE     A plasma generated within an induction coil is sampled  through a sampler orifice  into a first vacuum chamber stage and then through a skimmer orifice into a second vacuum chamber stage for mass analysis of trace ions in the plasma.  Arcing at the orifices is reduced or prevented by applying, to the plates containing the ori-fices,  an  RF  bias  voltage derived  from the generator which powers the coil.  Since optimum ion transmission is highly dependent on  the phase and amplitude of the RF bias, phase and amplitude adjustment networks are pro-vided to optimize the ion count.   Alternatively, arcing at the sampler orifice can be eliminated by grounding the induction coil at or near its center and the RF bias can be applied only to the plate containing the skimmer ori-fice.

Abstract: ABSTRACT OF THE DISCLOSURE A digital radio system with mobile and base stations is disclosed in which the base stations vary the transmitting power of the mobile stations according to the transmission quality. Criteria of the transmission quality are given. For example, in one case, the digital signals which are transmitted are encoded by an error-detecting or error-correcting code such that, in addition, the mobile stations vary the transmitting power of the base sta-tions according to the transmission quality, the rate of detected or corrected transmission errors being regarded as the transmission quality criterion. The advantage offered by the invention lies in the fact that signals which interfere with the communication but do not change the contents of the transmitted messages will not cause the receiver to increase the transmitting power. Accord-ingly, a change in transmitting power will be effected only if the useful signals cannot be reliably detected or processed.

Abstract: ABSTRACT     A paint spray booth in which articles such as automobiles are sprayed while moving along a conveyor line passing through the working area of the booth.          Air is moved from an area above the articles and downwardly around the articles for discharge through a plurality of longitudinally spaced vertical passages positioned along the center line of the booth and water supplied to a pan positioned beneath the articles is caused to cascade down the vertical passages for mixture with the spray-laden air so that the spray is transferred from the air to the water.          As the air leaves the lower ends of the vertical passages, it is directed laterally to impact one side of the booth, thence abruptly upwardly to separate entrained water, and thence in the other lateral direction toward the other side of the booth for passage through the spaces defined between the vertical passages.  The air discharged from the exhaust stack of the spray booth is substantially free of water and hence may be discharged into the atmosphere.

Abstract: Abstract of the Disclosure Seal Ring Means For A Bladed Rotor Assembly Bladed rotor assemblies having removable blades are used with gas turbines to reduce costs and increase serviceability.  Complex structures were used in the past to retain the blades within the rotor and seal the space therebetween.  Complex tooling and methods were required for replacement of worn or damaged blades.  Replacement of such blades by using the present invention reduces the complexity of the service required and reduces maintenance costs.  The bladed rotor assembly of the present invention has a rotor with slots, an outward facing groove and an opening in the rotor.  The blades are mounted in the slots and have an inward facing groove therein.  The grooves form an annular T-slot. A ring segment and a spacer are rotatably trapped in the T-slot and a device prevents relative rotation between the ring segment and/or the spacer, and the rotor.  The rotor assembly enables replacement of damaged blade on an individual basis by a simple disassembly-assembly technique which is inexpensive and requires low cost tooling.  The device preventing rotation is removed from the rotor and the ring segment and the spacer are rotated to align the opening and the spacer.  The spacer is slipped from the T-slot.  The ring segment is aligned so that each damaged blade is replaced.  After all the damaged blades are replaced, the ring segment is aligned with the opening, the spacer reinserted and the ring segment and spacer rotated to a position where prevention device is fixedly attached to the rotor.
