Title: Electrolysis appts. for extracting or refining metals - electrolyte flows parallel to electrodes of several consecutive cells in common bath
Inventor: RABBEN HANS JOACHIM DIPL CHEM
IPC: C25C7/00
Filed: 1973-06-27
Abstract: Simple, economic electrolysis appts in which the electrolyte flow accelerates diffusion at all electrode surfaces for a single expenditure of kinetic energy, with insertions on the two end faces to ensure a uniform velocity distribution across whole width of cell of the electrolyte flowing parallel to the electrode surfaces, has several cells connected consecutively in a common bath without dividing walls. All electrode surfaces are parallel and the distance between 2 consecutive electrodes in 2 different cells is at least 4 times that between 2 electrodes in same cell. Linear distance between 2 consecutive cells can be reduced by inserting deflection plates made of non-conducting material. Flow promoting diaphragms used to separate anode and cathode space.

Title: Crossbar-type conveyor edge connecting link - has head and foot offset in travel direction with bar bores
Inventor: POERINK JANNES JONGE
IPC: B65G17/08
Filed: 1973-09-06
Abstract: The link has a foot with a bore accommodating one crossbar, and a head, offset from the foot in the direction of travel, and also with a bore for the next cross-bar. There can be two head portions with bores, the foot from the adjacent link fitting between them. A sleeve can be fitted in the head, and the bore in the foot can be hyperboloid in shape.

Title: Lead stops for component insertion depth - component leads are immersed in tin bath with high melting point
Inventor: BERGMANN MICHAEL
IPC: H01G2/06
Filed: 1973-09-14
Abstract: The method produces stops on the insertion leads of electrical components for restricting the insertion depth of the component on a PWB. The connection leads of the components are dipped into a tin bath to a depth so that the tin bath surface meets the leads at the point of the intended stops. The tin bath composition and with it the melting temperature of the tin and the bath temperature are chosen corresponding to the heat conduction and heat capacity of the leads and connected component parts in such a way that the tin bath solidifies at the surface around the leads forming a bulge and when extracted that the bulge remains at the intended position.

Title: Hydraulic restrictor valve with linear flow-pressure drop character - control characteristic modified by feeding back output pressure
Inventor: SANDAU HARTMUT
IPC: G05D7/01
Filed: 1974-05-15
Abstract: A hydraulic restrictor valve utilises pressure feedback to obtain a linear characteristic between input flow and pressure drop. Input flow through a port (13) is throttled by a controlled needle valve orifice formed between a moveable needle (27) and a fixed orifice (21) in a plug (18) in a bore (12). The needle is part of a stem (26) on a piston (25) that is axially biased by a disc spring (29) retained in the valve body. The axial loading is set by moving the fixed orifice plate (18) with a screw thread adjuster (23). When inlet flow is connected the piston (25) moves to allow passage to outlet (14) over the orifice.

Title: Consolidated plastic bodies prodn - by forming sheet of consolidated bodies-dividing sheet into separate bodies
Inventor: KASTING HOWARD EDWARD
IPC: B01J2/22
Filed: 1974-10-23
Abstract: Continuous prodn. of consolidated bodies of plastic matl. is effected by supplying a thermally softened matl. stream to a rotatable consolidating zone to form a sheet of consolidated bodies that are connected together, and comminuting the sheet to form consolidated bodies of similar shape. The process enables strong consolidated bodies to be produced efficiently and rapidly from a wide range of thermoplastic matls., e.g. PVC and polyethylene. Thermosetting resins e.g., phenolics, having a high filler content can also be used, providing that premature crosslinking is avoided.

Title: Gear wheel made from compound material - has metal main body and plastic outer rim
Inventor: LOTTERSCHMID EUGEN
IPC: F16H55/16
Filed: 1974-10-25
Abstract: The gear wheel consists of a metal hub and disc in the outside diameter of which a 'T' groove is machined. A plastic rim is moulded round the gear disc which fills up the groove in the disc. The gear teeth can be moulded in at this stage or machined on later. The thickness of the plastic rim and the depth of the T groove are chosen so, that the distance of the root of the teeth to the outside of the metal disc (x), is less than half the distance of the root of the teeth to the bottom of the groove (y). The use of plastic teeth prevents the necessity of machining the teeth so that they taper gradually from the centre to the ends.

Title: Non-metallic bale tying mechanism - two needle parts separately rotated to twist loops and hold wires (NL220676)
Inventor: BLECKMANN JOST
IPC: B65B13/28
Filed: 1974-12-20
Abstract: A mechanism for tying bales of wastepaper etc., each thrusting against the preceding one during compression, uses one or more wire loops, each consisting of two wires joined together, and the bale pulls them off separate coils so as to form a loop enclosing it on three sides. A two-part needle slides at right angles to the direction of bale movement, bringing the portion to enclose the fourth side of the bale, forming two loops in the process, into a position where the loops are twisted together. The lengths of wire joining the twisted loops are then parted off. Each part (18, 19) of the needle can be rotated about its lengthwise axis for the separate twisting of the loops already formed, and also to maintain the connection between the ends of the two wires.

Title: Driving mechanism for industrial mechanical vibrator - uses rubber rollers to transmit drive between out-of-balance shafts
Inventor: MUSSCHOOT ALBERT
IPC: B65G27/32
Filed: 1975-03-21
Abstract: Vibrators used for driving mechanical sieves employ a pair of parallel shafts (48, 50) mounted in bearings (40, 42, 52, 54). The shafts carry eccentric masses (62, 64) and are arranged to rotate at equal speeds but in opposite directions. The line of the resultant centrifugal force is arranged to pass through the centre of gravity of the sieve but as the material moves, the centre of gravity also moves. With a toothed gear drive this shift of the centre of gravity causes tooth wear. The invention proposes using rubber rollers (76) which allow a degree of slip so that the line of action of the force is automatically adjusted to pass through the centre of gravity.
