Title: Device for producing pellets, esp. from vegetable matter - has punches on rotating drum force material through dies on surface of second parallel rotating drum and pellets are removed from drum interior
Inventor: HAIMER FRANZ
IPC: B30B11/28
Filed: 1990-12-04
Abstract: A device for making pellets consists of two parallel contra-rotating drums whose surfaces contain punches (13) and dies (12) which engage each other as the drums rotate. Pellets are therefore pressed from the surfaces of the drums into their hollow interiors (14). The drums are driven in synchronism with each other. Each drum may contain both punches and dies, or one drum may contain only punches and the other only dies. The punches and dies may be round, hexagonal or recetangular in shape. The dies are conical. Scraper elements or screw conveyors (16) may extend into the interiors of the drums. The drums are surrounded by a housing except at the material inlet point (7). Scrapers (21) extend between the projections formed by the punches. A feed mechanism is provided at the material inlet point and is controlled in accordance with the throughout rate of the drums. This mechanism may consist of speed-controlled rollers (10). USE/ADVANTAGE - Used in the mfr. of pellets, from vegetable substances. The proposed device has a very high throughput and low wt., and occupies little space. It is suitable for use in a mobile harvesting machine.

Patent DE-4212097-A1 (DE)
IPC: B22C5/02
Filed: 1992-04-10
Abstract: A regeneration process for foundry sand, in particular active bentonite-containing used sand, dispenses with preliminary thermal treatments and allows most valuable substances contained in the used sand to be recovered. The sand is partially fluidized with air in a grinder, by means of which valuable substances and dust are continuously carried out and separately collected. The considerably increased grinding and dedusting performance requirements caused by the suppression of preliminary thermal treatments are met by a composite system of separate grinding and dedusting areas through which the sand continuously circulates in a vertical circuit.

Title: Transport device moving cigarette packets along transport path - has two horizontally rotating distributor discs with circumferentially spaced projections to move packets individually during transport.
Inventor: FOCKE HEINZ
IPC: B65G47/71
Filed: 1992-04-22
Abstract: The radial projections (37,38) slide the packets into a recess (39,40) in each other disc (33,34). The recesses are each aligned with one or other discharge row (30,31) along which the packets are delivered. The distributor discs each have three evenly spaced projections. The discs which rotate oppositely at the same speed are set in relative positions so that one projection of one disc each opposes a recess in the other. The packets arrive on the incoming conveyor belt (17) at a greater speed than the rotary speed of the discs and projections. Each incoming packet is moved against a stop (43) of the relevant disc. USE/ADVANTAGE - Faster processing speeds but with smooth handling and division of the cigarette packets into two rows.

Title: Drive system for printing cylinder - Incorporates hydraulic release system to allow phase adjustment of cylinder
Inventor: PETER GUNTER DIPL ING
IPC: B41F13/00
Filed: 1992-04-30
Abstract: The drive system is for a printing cylinder (3) in a multiple cylinder printing machine.

Title: High frequency surgery apparatus for cutting tissue - increases HF current until product of actual values of HF output voltage and current corresponds to adjusted power value
IPC: A61B18/12
Filed: 1992-05-31
Abstract: The high frequency surgery appts includes a voltage sensor (9) to monitor the actual value of the HF output voltage UHF (Uist). The actual value (Uist) is compared with the desired value (Usoll). A device (11) calculates, for a deviation of the actual value, (Uist) from the desired value (Usoll), a maximum value (Imax) for the UF current (IHF) at an adjusted maximum HF-power (Pmax) and actual value (Uist). The calculating device generates an electrical signal (K) to an electronic power supply (7) to supply a current (IHF) to the output of the HF generator. The UF current is increased until the product of the actual HF output voltage (Uist) and actual value of HF current (Iist) corresponds to the adjusted power (Pmax). For actual HF output voltage (Uist) to equal desired value (Usoll) is dependent only in the resistance between the active and neutral electrode. ADVANTAGE - Generates short duration and also higher HF current or HF power if necessary.

Title: Triboelectric charging of particles - by two-stage positive and negative charging process for complete particle sepn.
Inventor: GELLERT BERND DR
IPC: B03C7/00
Filed: 1992-07-11
Abstract: In the electrostatic charging of particles by passage through a frictional charger, the novelty is that: (a) the particle stream is passed through a first charger (R-), in which a portion of the particles is negatively charged; (b) the charged particles are separated and removed; and (c) the particle stream is passed through a second charger (R+), in which the remaining particles are positively charged and then opt. separated from uncharged particles and removed. The triboelectrically active material, used in the second charger, is pref. PTFE. The triboelectrically active material is a rare earth metal (pref. La and/or Ce) alloy in the first charger (R-) and a plastics (pref. PTFE) in the second charger (R+). The particle stream, fed to the second charger, is pre-mixed with a positively ionised gas (pref. nitrogen) to remove excess charge on the triboelectrically active material of the second charger (R+). Particle charging in the first and/or second charger is assisted by an electric field and charged particles are sepd. from uncharged particles, after leaving the charger, by the action of an electric field of reversed polarity. USE/ADVANTAGE - The process is used in electrostatic sepn. of particles, e.g. sepn. of ash-forming and sulphur-contg. components from coal dust, recovery of plastics fractions from mixed plastics waste and paint changing in the electrostatic painting of automobile bodies. It provides complete separation of particle fractions.
