Abstract: Low temperature embrittlement of materials which otherwise cannot be readily comminuted is carried out by treating the materials, g.g. scraps of synthetic resin containing components which might otherwise be released into the atmosphere, with a circulated cooling gas to cause the embrittlement of the materials. The latter are then conveyed through a mill, e.g. a pin-type attrition mill, in a carrier gas and are comminuted therein. The cooling gas is passed continuously around a closed circulation path so that any released components remain trapped in the circulated gas which, in turn, is cooled to a sufficiently low temperature by a separately displaced cooling fluid passed in indirect heat exchanging relationship with the cooling gas stream along the closed path of the latter.

Abstract: A cylindrical milling chamber of a disintegrator is made in such a manner that the width thereof is substantially smaller than the diameter. An opening for feeding the material being disintegrated is provided at the center of one of the end walls of the milling chamber, and openings for discharging suspension of the disintegrated material are provided on the cylindrical surface of the milling chamber. At the center of the milling chamber there is provided an agitator for milling bodies mounted concentrically therewith. The milling bodies are made of a material having a density corresponding to the density of suspension of the material being disintegrated. The milling chamber considerably reduces the adverse effects of temperature and pressure on the material being disintegrated, such that overdisintegration of the material is eliminated. At the same time, the specific productivity of the disintegrator is improved by 10.sup.2 times.

Abstract: The invention relates to slug riveting apparatus wherein a pair of opposed rivet head forming anvils move relatively toward each other to form heads at the opposite ends of a cylindrical rivet blank, more or less simultaneously, after the blank has been inserted in the workpieces. An annular elastomeric polyurethane member is associated coaxially with one of the rivet head forming anvils and has a bore for receiving and resiliently gripping a cylindrical rivet blank. The elastomeric annular member holds the blank during insertion of the blank in the workpieces as the anvils move relatively toward each other, and the rivet blank is moved out of engagement with the elastomeric annular member by the associated head forming anvil during the head forming operation by resilient radial expansion of the elastomeric annular member. The rivet forming anvils have flat bottomed head forming recesses with sloping side walls.

Abstract: Unobstructed free discharge from the end of an auger into a granulator assembly is achieved by supporting the auger shaft cantilever fashion and effecting driving of the shaft at the end of the conveyer trough remote from the end of the trough which discharges into the granulator assembly. This eliminates wrapups or binding of thermoplastic material, especially long flexible pieces fed by the auger to the granulator assembly.

Abstract: This invention relates to an improved pneumatic power driving tool for driving staples, nails and other fasteners. The tool is comprised of a pneumatically operated pivoted rectangular hammer which is used as the means for delivering a force to a ram which in turn drives the fastener. The pressure in an air reservoir provides means for determining the impact of the hammer in this tool. A hammer activated valve is employed to index a fastener before a driving force is applied to the fastener by the hammer.

Abstract: Household or industrial refuse is first passed through a device which rips open garbage bags, breaks open cardboard boxes, and breaks up bundles. Then this refuse is passed through a magnetic separator that extracts all the ferromagnetic elements. Thereafter the refuse is subjected to a coarse comminution and passed through a sieve to eliminate particulate material. The sieved refuse is then fed to an air-classifier which separates it into heavy, medium-heavy, and light fractions. The medium-heavy fraction is more finely communited, then passed through a zig-zag air-classifier and a cyclone to recover material usable in the production of paper, which is combined with the light fraction from the air classifier for reclamation.

Abstract: A wet grinding device having a container for receiving therein products to be ground as well as grinding balls, the container being equipped with a mixer, a delivery device for feeding the products to be ground into the container, a discharge outlet for the broken-up products, as well as a drive device for the mixer. The wet grinding device is characterized by an operating chamber divided into a plurality of grinding zones of increasing volume, the operating chamber including a mixer shaft therethrough, the latter being rotatably horizontally supported by the container. The shaft is provided with blades which have a diameter which is proportional to the diameter of the respective grinding zones.

Abstract: In a system for comminuting materials containing thermoplastics, the temperature in the comminuting chamber is monitored and a spray of cooling liquid is charged into the cutting chamber when the cutting chamber is at a temperature greater than the boiling temperature of the cooling liquid and less than the melting temperature for the thermoplastic being comminuted. By using heat of vaporization to extract heat from the cutting chamber, the likelihood of the plastic softening and/or melting and clogging the comminuting screen is substantially reduced. A higher throughput of materials is obtained because of material remaining harder. By vaporizing the liquid, the discharged comminuted material may be maintained very dry for later classifying. Preferably, the cooling liquid is discharged intermittently to keep the temperature of the comminuting chamber within predetermined upper and lower temperature limits.

Abstract: A container contains a plurality of strips or rows of nails adhesively secured together and a wedge block splits off one row at a time for dispensing. The separated strip of nails is moved forwardly by means of a magnet so that the front nail of the strip is situated through an aperture and under a tappet. This tappet is struck lightly with a hammer which separates the front nail and enables it to be partially engaged within the work surface. The tappet is spring loaded or counterweighted in order to return it to the uppermost position.

Abstract: Ashes and cinders which form during gasification of solid combustible substances are captured in a liquid body and form clinker granules of different sizes therein. A comminutor is arranged below the chamber in which the liquid body is accommodated so that the clinker granules descend into the comminutor in which the clinker granules are reduced to clinker particles having sizes equal to or smaller than a predetermined size. The comminutor may have two comminutor rollers rotated by respective drives in opposite directions about parallel horizontal axes. The drives are arranged outside and mounted on the comminutor housing, and are connected to the respective comminutor rollers by shafts penetrating through the comminutor housing and sealed by shaft seals. The comminutor may, in the alternative, include a single comminutor roller which cooperates with a grating tiltably mounted in the comminutor housing.
