Abstract: ABSTRACT OF THE DISCLOSURE A shock absorbing roller for mounting on a shaft having a central axis and for movement along a track, including a central hub portion for mounting the roller on the shaft, a roller portion surrounding the hub portion and including means interconnecting the peripheral roller portion and the hub portion and supporting the roller portion, and the roller portion including a flexible circumferential flange section extending outwardly away from the central hub portion and at an acute angle relative to an axial bore through the central hub portion for providing contact with the track and with the flexible circumferential flange section providing shock absorption and noise reduction on movement of the roller along the track. The roller is used as a part of a door assembly such as used for garage doors or truck doors and comprising a plurality of interlocked door panels.  The roller is quieter in operation since it is shock resistant in other or both the vertical and horizontal directions.  The usual loud clattering associated with such a door assembly is substantially eliminated when this roller is used.

Abstract: Radial Lead Inserting Machine Abstract of the Disclosure Endwise insertion of leads projecting generally radially, or substantially in parallel, from one side of each of a plurality of interconnected electrical components is effected in rapid reliable succession. The components are sequentially fed into the head of a machine by a tape indexing mechanism. There, when aligned with a reciprocable inserter, the leads of each component after being cut to predetermined length are separated from the tape by spaced members acting transversely on the progressively guided tape. The lead cutting and their separation from the tape with the aid of lead grippers controlling the attitude of each component are effected substantially in alignment with insertion mechanism of the head operable cyclically on the successive components to effect their axial insertion; accordingly the arrangement provides a high-speed inserting cycle during which a reciprocable driver, acting through ball transfer means, actuates a component pusher, lead gripping fingers, and knives whereby each lead is continuously controlled as to its shape and position.      Although herein illustrated for use at a conveyorized station of component assembling apparatus and hence adapted with but a single channel for supplying similar components, the machine, with minor modification, is also useful with multi-channel component feeding arrangements.

Abstract: ABSTRACT OF THE DISCLOSURE         Tobacco impregnated with solid carbon dioxide is heated in a chamber to expand the same by sublimation of solid CO2 and expulsion of CO2 gas from the tobacco.  The expanded tobacco is separated from the internal atmosphere of the ex-pansion device and the tobacco is discharged through an outlet through which gas flows are substantially precluded.  The evolved CO2 gas and other volatile components are removed from the chamber and a portion of the removed gas is heated and returned to the chamber as the expansion medium.  The necessity for external steam is avoided as an atmosphere of high thermal diffusivity is maintained in the expansion chamber by precluding the entry of ambient air.

Abstract: ABSTRACT OF THE DISCLOSURE          Method for forming mixed oxide and/or nitride films upon the surface of an article by the use of a partially confined plasma-activated source.  The plasma-activated  source has a cavity in which an RF field is formed within the cavity to create a gas plasma in the cavity as gas is introduced into the cavity.  The gas plasma is caused to exit from the cavity to impinge upon the surface of the article to be coated.  At least one of the constituents of the film is selected as a compound vapor and is chemically reacted with at least one other constituent by utilization of the gas plasma to form the thin film on the surface of the article while the article is maintained at a low temperature.  A chemical reaction takes place within the cavity itself and/or alternatively at the surface to be coated for the formation of the films.

Abstract: ABSTRACT OF THE DISCLOSURE         A DC power transmission control system for a DC line inserted between a pair of converters comprises a transformer provided on the AC side of each of the converters for maintaining constant the no-load voltage on the converter side by tap position control.  One of the converters is operated as an inverter for control of the DC voltage.  The control angle of the converter operated as the inverter is controlled by a signal associated with, e.g., a DC current as a load.  The DC terminal voltages of the converters are made variable, thus reducing the amount of increase in the reactive power of the rectifier under a small load condition.

Title: Glass firescreen with air curtain for wood  stoves and firplaces
Inventor: KIM CHUN KON GEORGE
IPC: F24B13/00
Filed: 1980-05-05
Granted: 1982-07-06
Abstract: ABSTRACT           A conventional firescreen made from a heat resistant glass, used for an open wood burning stove or fireplace, is known to be much more efficient in the prevention of heat loss than a firescreen made from a steel wire mesh or a perforated steel plate.  However, the glass firescreen can easily become stained by soot and smoke which therefore requires numerous cleanings.          There is also the possibility of the glass shattering if a fire is allowed to become too large and hot.  In this invention, the glass firescreen has an air intake diverting plate situated behind the glass plate at the lower and/or side portions of the glass frame allowing the formation of a moving air curtain over the rear surface of the glass which will protect the glass from the soot, smoke and excessive heat, and thereby assist in preventing said stain formation.

These two circulating stores are synchronous and have data word registers and random address registers respectively associated two by two. The bytes in the time-slots of an incoming supermultiplex highway are written in the data word registers and addresses depending on the outgoing time slots which are to be connected are written in the random address registers. These addresses are incremented at each step of the random address circula-ting store. When the incremented address reaches a prede-termined value, a data word is read in the data word cir-culating store.

Abstract: ABSTRACT OF THE DISCLOSURE     A powder of a slag formed at the time of manufacturing steel is used to remove heavy metals contained in waste water.          After use, the slag may be heated to recover the heavy metals adsorbed thereby or the used slag may be formed into solid blocks, balast or aggregate by admixing with Portland cement or alumina cement.  The slag utilized in this invention can be ob-tained in a large quantity at low cost.  The heavy metals once adsorbed by the slag is stable and does not readily dissolve in water.  Thus the invention is useful to prevent public hazard caused by waste water containing harmful heavy metals.

Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed a process of preparing vinyl dispersion resins by conducting the polymerization re-action of the vinyl monomer or monomers in an aqueous medium in the presence of a polymerization initiator or catalyst and an emulsifier or emulsifier system to form a vinyl resin latex, which is then subjected to an ultrafiltration step by forcing the same through a semipermeable membrane leaving behind the polymer parti-cles and reusing the permeate, which contains dissolved monomer(s) and emulsifier, in the further production of vinyl resin latices.  Unexpectedly, further use of the permeate substantially reduces polymer buildup in the reactor and since the ultrafiltration step increases the polymer particle concentration in the latex, considerable heat energy is saved in the spray-drying step.
