Title: Blow torch for lead soldering has ring of fine jets - spaced behind main jet subdivided into bundle of parallel channels
Inventor: KRAUSHAAR MANFRED
IPC: F23D14/52
Filed: 1975-01-15
Abstract: In the blow torch the cylindrical main jet (casing 3), which is at least three times as long as it is broad, is surrounded by two groups of fine, flame-stabilising jets viz., an inner ring of open channels (13) ribbing the outside of the long jet casing, and an outer ring of shorter, closed channels (9) perforating a surrounding collar (2). The noise of the resulting stabilised flame (fed from 4 via 19, and 20) is reduced by half when the single main jet is replaced by a number of fine jets (16, 17, 18), formed either of a square-ended bundle of fine tubes or or a parallel-perforated block.

Title: Textile hydro-extractor - has flat receiver on rotor, for loading during operation, with removal between receiver and cylindrical wall
Inventor: CALAMAI GIORGIO
IPC: B04B11/05
Filed: 1975-03-25
Abstract: Textile hydro-extractor includes a rotor with a liq.-permeable cylindrical wall to which the textile adheres during treatment under centrifugal action. A flat receiver is fitted on the rotor for loading during operation and distributing the material, and is flat and disc-shaped, with its edge spaced from the wall. The material is fed in free fall to the receiver, and is thence centrifuged onto the wall. The treated material is trapped when it falls through the gaps between the wall and the edge of the receiver, when the rotor, held in bearings on opposite sides of the receiver, is stopped. The rotor's speed can be low when feeding in material, rising to a high, water-removing speed before stopping.

Title: Wort circuit for beer breweries - using external boiler under pressure and collecting sediments by whirling motion in wort pan
Inventor: WIEDERHOLD JOHANNES
IPC: C12C13/02
Filed: 1975-08-06
Abstract: Wort is treated in beer breweries by circulating it between a wort pan and an external boiler. During a part of the heating and boiling operation, pref. outside the wort pan, the wort is kept under pressure and the boiling temp. is maintained. The pressurised heating and boiling under pressure speeds up these operations (from 90 to 20 min.). A special whirlpool vessel for the sediments can be saved. The wort pan need not be a pressure vessel, which reduces its costs. The wort is kept at a pressure of 2 atmospheres outside the wort pan, i.e. in the external boiler and the pipe sections. On completion of the boiling operation the wort is introduced in and removed from the wort pan by tangential pipes. The wort is set into a whirling moition and the pptd. sediments are collected in the centre of the whirl.

Title: Edge seal for asbestos electrolytic diaphragm - produced by high temperature impregnation with high melting point wax
Inventor: ZDANSKY A EWALD
IPC: C02F1/461
Filed: 1976-01-07
Abstract: The diaphragm consists of an asbestos sheet which is impregnated along its edges with a high m.p. hard wax such as paraffin or polythene wax. The wax provides good impregnation and hence a good edge which is impervious. The wax also acts as a good cushion when the sheet is pressed between the metal frames and absorbs unevennesses hence producing a good gasket.

Title: Spot welding appts. with electronic circuit to control current - for mfr. of steel cages for reinforcing concrete pipes
Inventor: MUENDEL GUENTER
IPC: B21F27/12
Filed: 1976-07-13
Abstract: Electronic control circuit is provided for the resistance spot welding of steel rods in mfg. cases for reinforcing concrete pipes etc. The welding electrodes are fed periodically from a transformer, using a timer controlled by the movement between the electrodes and the rod junctions. The timer is coupled via a clock generator to a controller fed with a signal (Sa) representing the actual welding current, and the desired, reference currents (Sr). The controller adjusts the welding voltage according to the output signals of the clock generator, and supplies a voltage to the transformer which is inversely proportional to the alteration in Sa. In the pref. electronic circuit, a thyristor stage is connected in series with the prim. of the transformer, and actuated by a logic circuit included in the clock generator. Used for accurate control of welding current to obtain strong welds which are subject to inspection involving vibration combined with tensile stress.

Title: IC engine air fuel ratio regulator - has auxiliary air intake controlled by depression dependent diaphragm
Inventor: RAMOS PROCESO P
IPC: F02M23/09
Filed: 1976-11-10
Abstract: The air fuel mixture regulator consists basically of a depression dependent diaphragm whose movements are transferred to a valve unit. The relative position of the valve permits auxiliary air to enter the induction manifold proportionally to engine requirements as in 2508080. The regulator is fitted as an independent unit to an existing carburettor layout. The diaphragm chamber is connected by an air tube (4) to the carburettor venturi. The air valve has an axial bore (12); one end is connected to an air filter (3) and the second end (15) is connected to the inlet manifold downstream to the carburettor flange. The bore cross-section can be modified by a fast running (14) and a slow running (13) set screw. The diaphragm movement is transferred by means of a push rod (6) to a valve (11) able to slide in a radial bore bi-secting the axial bore. The valve abuts against the slow running set screw (13).

Title: Mould residue removal from castings in mass prodn. - using high voltage discharges in water bath through which castings travel
Inventor: KOSTYRKIN BORIS V
IPC: B22D29/00
Filed: 1976-12-21
Abstract: Plant is used to remove mold residues from castings by high voltage discharges in a liq., e.g. water. A double chain conveyor, fitted with loading and unloading devices, carries the castings continuously through a zone (a) in the water bath; and the number of electrode units located in the treatment zone (a) is the same as the number of castings travelling through zone (a). The electrode units are pref. hinged on the conveyor frame so the electrode tips move together with the castings through zone (a), while driven gear wheels mounted on one side of the bath use grippers to rotate the castings while they travel through zone (a), i.e. so all the surface of each casting is treated to the electric discharge. Used esp. in mass prodn. to remove the residues of shell moulds from the castings, together with ingates, scale, rust, oil, etc., thus polishing the castings.
