Title: Central inlet centrifugal pump - has magnetic drive via housing wall with fixed impeller hub and axial bearing preventing wall deformation
Inventor: WIENEN KURT
IPC: F04D13/02
Filed: 1979-06-16
Abstract: The centrifugal pump is driven via a magnetic coupling and comprises a housing with a central inlet and radial outlet. The drive side of the housing has a non-magnetic housing wall with a hub on which the impeller with magnetic poles rotates. Within a bearing housing a magnetic rotor carries drive poles and is driven by an input shaft. Deformation of the housing wall due to pump pressure and consequent movement of the fixed impeller hub is prevented by at least one axial bearing. The rotor may be hollow and carried on bearings on an extension of the fixed hub.

Title: Removal of acid constituents from boiler flue gases - using fraction abstracted before air preheater in spray dryer
Inventor: BECHTHOLD HORST DR ING
IPC: B01D53/34
Filed: 1979-07-14
Abstract: A small fraction of the exhaust gases which pass from a boiler to the air preheater and from there go on to a dust extractor and a desulphuriser before reaching the chimney stack, is drawn off before the preheater, in a process for the removal of acid components. This fraction is put through a spray vapouriser, and from there goes to a separator, following which, before or after the dust filtration plant, it is put back into the main gas flow; the washing water from the desulphurising plant being put wholly or partly through the spray vapouriser. For application in coal or oil fired power stations in which the gases of combustion on leaving the boiler, go through a preheater for the air and then are cleaned in a desulphurising plant. Simple means of removing the noxious substances from the flue gases, which can be installed in already existing power stations, to bring down operating costs, is provided.

Title: Load-controlled inverter for induction furnace - has valves in bridge for bringing load capacitance and inductance oscillation without additional power circuit components
Inventor: DREES GERD-WILHELM DIPL ING
IPC: H02M7/523
Filed: 1980-06-25
Abstract: The load circuit of the inverter (4) is connected across the diagonal of the bridge and comprises a capacitor (C1) in parallel with a series combination of capacitor (C2), resistor (R) and inductance (L). The latter two components represent the furnace and its charge. The proposed starting process operates in three steps. First, one diagonal of the bridge (VA1,VA2) is turned on. Current flows from the d.c source (1), charges the capacitors, and the valves (VA1,VA2) extinguish at current zero. A short circuit is then applied to the system by firing two valves in series (VA1,VB2). At a certain current value the third stage is initiated by firing a diagonal valve (VA2). The short circuit current diverts to the incoming valve. At this stage the oscillation has in effect been started. A voltage is developed across the capacitor bank (C1) which ensures a current flow through the load in each half cycle.

Title: Vinyl chloride homo-, co- or graft polymerisation - using catalyst mixt. contg. cumyl per-neo:decanoate and further peroxide gp.-contg. catalyst(s)
Inventor: KRAENZLE ROLF DIPL CHEM DR
IPC: C08F2/18
Filed: 1980-08-01
Abstract: Vinyl chloride homo-, co- or graft copolymers are prepd. by polymerising vinyl chloride alone or with up to 30wt.%, w.r.t. vinyl chloride, of at least 1 copolymerisable monomer and/or of at least 1 polymer which is graft-copolymerisable with vinyl chloride. Polymerisation takes place in aq. suspension or bulk, at 30-80(40-65) deg.C, opt. with the addn. of dispersants and other additives. Novelty consists in using an oil-soluble catalyst system contg., by wt. w.r.t. monomers, (a) 0.001-0.5(0.01-0.1)% cumyl perneodecanoate (A), and (b) 0.001-0.5(0.01-0.1)% of at least 1 further standard peroxide gp.-contg. vinyl chloride polymerisation catalyst (B), having 1 hr. half-value temp. 50-100 deg.C. Deposit formation on reactor wells is reduced, thereby reducing faults, e.g. fish-eyes or flecking in thermoplastic working. Polymerisation batch running time, to achieve a given conversion, and max. heat removal, expressed as temp. difference between internal polymerisation reactor temp. and cooling jacket temp., are reduced.

Title: Electromagnetic flow meter - uses pulsating alternating current for coils with short time duration and has magnetic circuit with high permeability yokes
Inventor: UENO KAZUO
IPC: G01F1/58
Filed: 1980-08-06
Abstract: The power consumption of the flow meter is decreased by applying to exciting coils (5a,5b) a pulsating alternating current (1) with short time duration. The velocity of flow of fluid in pipe (1) is determined using the voltage produced between electrodes (2a,2b) during a predetermined constant period. This is from the point when the flux in the magnetic circuit reaches a stable level and no exciting current flows in coils. The magnetic circuit may be comprised of a series coupling of a yoke made of high permeability with low residual magnetic flux and a permanent magnet.

Title: Sausage shading and portioning machine - with cellular wheel and synchronised revolveing cutter blade
Inventor: STIMPFL CHRISTOF
IPC: A22C11/10
Filed: 1980-08-25
Abstract: The filler spout of a sausage stuffing machine discharges the strand into the wedge space (3) where a cellular wheel (1) with partitions (6) and cells (5) squeezes it into shape against an endless belt conveyor (4). A revolving cutter blade (2) severs the sausage end, which has been squeezed flat, against the plastic back-up roller (11). A cantilever extension (7) of the belt conveyor takes the individual sausages to the next stage. The panel (10) acts as a guard plate. The machine enclosure carries all instruments and controls (8,9). This saves the manual labour of at least two operators and makes the whole operation more hygienic.

Title: Joining unvulcanised rubber strip butt - by first heating ends then pressing together before releasing
Inventor: ANDERS UWE DIPL PHYS
IPC: B60J10/23
Filed: 1980-10-09
Abstract: Unvulcanised or partly prevulcanised rubber strips are butt-jointed using two pairs of grippers holding the strip near its ends. The ends are first heated to at least 100 deg.C by placing a heated plate temporarily between them, the plate is then removed, the grippers are temporarily brought together to press the ends together, and then the grippers are simultaneously opened to release the strip. Pref. the pairs of grippers are accurately profiled to the cross-sectional form of the strip. Internal shells in the grippers to suit different types of strip may be interchangeable. Used esp. for vulcanising of a closed ring or similar closed strip or beading, e.g. for framing of an automobile window, where the cross-section is comparatively complicated. Method enables a firm joint to be produced without any cracking and for different types of rubber mixts.

Title: Poultry transfer to monorail hooks - by endless chain in oval horizontal path carrying troughs on hinged levers
Inventor: KAMPHAUS JOSEF
IPC: A22C21/00
Filed: 1980-12-20
Abstract: A system for the transfer of slaughtered poultry to the hooks of a monorail leading to subsequent processing stations consists of an endless chain in a horizontal plane from which a number of troughs are suspended. The chain is guided in an oval path and in one of the long stretches the path coincides with that of the monorail. The legs of the poultry protrude beyond the troughs and in the overlapping stretch the legs become wedged with the knuckle joint in the hook, assisted by a movement of the trough with carcass in the vertical plane. This saves the manual labour of several operators which are otherwise reqd. to deal with the usual transfer rate of 106 carcasses per min.
