Title: Improvements in or relating to lift control systems
IPC: B66B1/34
Filed: 1964-11-19
Abstract: 1,083,260. Measuring weight electrically. SCHWEIZERISCHE WAGONS-UND AUFZUGEFABRIK A. G., SCHLIEREN - ZURICH. Nov.19, 1964 [Nov.21, 1963], No.47135/64. Heading G1N. In measurement of the load in a lift cage eccentric loading is accounted for by supporting the lift floor at each corner, on springs of identical spring rate on the cage bottom, and the average change in height of the springs is detected and converted into an electrical signal representative of the total load. In Fig. 2 two lateral traverses 6 each rest respectively on a pair of springs 4 and a beam 7 joins the centres of the traverses. The displacement of the centre of the beam 7 on load, with respect to a point on a cross member 16 of the lift cage frame, thus represents the average deflection of the four springs. As the beam 7 is deflected it engages a lever 10 pivoted to the frame and the lever amplifies the displacement and operates a pressure switch 11; or alternatively Fig. 4 (not shown) the centre point of beam 7 may carry a plunger armature which is slidable in a coil fixed to the frame, to produce a change in the inductance thereof. Strain gauges may be used instead of the plunger and core. Instead of using the traverses 6 and beam 7 there may be diagonally disposed traverses or, the deflection of each spring may be sensed by a hydraulic cylinder or bellows mounted beside it Fig. 5 (not shown), and the four bellows are connected in a closed hydraulic circuit to a measuring cylinder or bellows. The liquid displaced in the four bellows on load results in a proportional elongation of the measuring bellows which is coupled to a plunger armature movable within a coil. As a further alternative there may be a plunger armature and coil adjacent each spring the displacements of which are summed electrically. There may be two concentric springs at each corner having different rates of compression for identical loads one being more sensitive to light loads.

Title: Combined air-inlet and outlet valves
IPC: F16K17/19
Filed: 1973-10-23
Abstract: 1438695 Valves BOPP & REUTHER GmbH 23 Oct 1973 [24 Oct 1972] 49321/73 Heading F2V A float controlled combined air-inlet and outlet valve assembly for liquids in pipes or containers comprises a housing 1 having a bottom flange 34 secured to the pipe or container and enclosing a casing 7 having indentations 8 to guide a float 3 longitudinally. The latter has a projecting boss 9 co-operating with a separate main valve disc 10 having sealing faces 11, 13 mating respectively with seating 12 and resilient seating insert 14 to control airflow through inlet or outlet passage 15. Valve disc 10 has a stem 16 guided in a tubular member 17 having a head 29 secured in a bore of housing cover 2 by plug 30. The latter has a cavity 31 vented to passage 15 by passages 32. An auxiliary valve is formed by an opening 27 in resilient sealing insert 14 and a co-operating closure plate 26. The latter is attached to a yoke 20, 21 which is pivoted at 23 to the top of casing 7 to form a hinged lever, the other end 19 of which engages under a lug 18 secured to float 3. When the pipe or container is drained, housing 1 empties and the water in casing 7 escapes through bores 35 causing float 3 to drop, taking with it main valve disc 10 and causing yoke 20, 21 to pivot and open the auxiliary valve. Thus airflow through both the main and auxiliary valves into the pipe or container takes place. When the latter is again filled with liquid, air is initially vented through both valves, urging of valve disc 10 in the closing direction being prevented by casing 7 which diverts the airflow around float 3 and directs it via openings 36 to passage 15, the disc 10 being situated at a lower level than openings 36. If after both valves have closed pockets of air should collect in the pipe or container these pass into housing 1 causing the liquid level to fall and float 3 to drop. Thus auxiliary valve 26, 27 opens to release the air, though main valve disc 10 is held closed by the internal overpressure.

Title: Process for the production of iodophors
IPC: C08F8/18
Filed: 1975-12-02
Abstract: Germicidal complexes of poly-N-vinylpyrrolidone (PVP) with iodine are prepared in the form of granules of virtually uniform composition and particle size. To this end, the following are required:   a) a solution and/or colloidal suspension of elemental iodine and of a water-soluble substance which supplies iodide ions, in a first solvent or solvent mixture and b) a solution and/or colloidal solution and/or suspension of PVP in a second solvent or solvent mixture which has different surface tension from the first solvent or solvent mixture. The PVP is at least partially soluble or wettable in the second solvent or solvent mixture. The substances dissolved or suspended in the first solvent or solvent mixture are insoluble or only sparingly soluble in the second solvent or solvent mixture. Component a) is added to component b) in small portions and with uniform mixing. A mixed phase system forms. After further mixing of the multiphase mixture, the iodine/PVP complex-containing agglomerates formed are separated off and dried. By means of the process, which can be carried out continuously, yields of iodophore granules of 75 to 100% can be achieved.

Abstract: 1485238 Making electrical connectors KABELUND METALLWERKE GUTEHOFFNUNGSHUTTE AG 5 Dec 1975 [24 Dec 1974] 50001/75 Heading B3A A method of producing contact jaws for electrodes of electric melting furnaces of electrically conductive material, e.g. copper or copper alloy, a ring is formed by open-die forging from a cast blank, turned internally to give a radius of curvature substantially corresponding to that of the electrode surface and the ring is divided into segments of the width of the contact jaws. The cast blank is upset, then perforated before rolling-mandrel open-die is carried out to achieve the approximate dimensions of the contact jaws. The ring is then finish-turned internally and rough-turned externally, divided into a plurality of part rings which are finish-turned externally before being cut into segments. Water cooling channels 7 are drilled from one end face, and connected at 8 to form a circuit. Piping 10 is welded to the segments for connection to coolant inlet and outlet pipes. Alternatively coolant channels are formed in either end face of the ring. Before or after drilling of channels 7 the side of the segment remote from the electrode may be machined to form a projection 11 which can be used to hold the contact jaw on to an electrode.

Apparatus for emptying bags comprises a vibratory conveyer 11 on which the bags to be emptied are placed, the conveyer having at least one opening allowing material released from the bags to fall therethrough into a hopper 19, a cutting device 20 projecting through the opening in the conveyer to slit a bag as it moves along the conveyer and gripping means 23 arranged over the conveyer to engage the upper end of a bag while its contents are discharging and subsequently discharge the emptied bag from the apparatus. The vibratory conveyer, to which full bags are fed by a cross conveyer 18, comprises a trough 17 provided with tubular bearers 16 which extend between the gripping means 23 and the hopper 19, the trough being supported from the frame 10 by leaf springs 12 and vibrated by an eccentric drive 13, 14, 15. The gripping device comprises opposed chains 23 (and 22, Fig. 2, not shown) fitted with spikes and driven by a motor 25 at an appropriate speed. The apparatus is of particular utility when the bags contain materials of a sticky material as the shaking action, which continues while the bag is gripped between the chains, helps to release such material from the bags.
