Title: Textile fabric - having air-permeable waterproof plastic coating
IPC: D06N7/00
Filed: 1973-02-20
Abstract: An air permeable textile fabric (e.g. a brushed cotton fabric) is coated with a uniform array of closely arranged spots of thermoplastic material (e.g. a monocomponent linear polyurethane dissolved in 3 parts DMF and 2 parts MEK) and then heated and pressed to flatten the spots such that they join together to produce a waterproof coating having capillary holes through which air can pass. The fabric may be pressed between presser rolls which may be embossed and one roller may rotate faster than the other to produce friction on the fabric which heats the thermoplastic material to provide a smoother coating. The water proof fabric is esp. used for clothing and can breathe easily, thereby reducing condensation.

Title: Locking mechanism for LV cct. breaker - has switch arm pivoted by rotating cam to cause arm contact to touch fixed contact
IPC: H01H71/52
Filed: 1973-07-18
Abstract: The locking mechanism for a low-voltage circuit breaker, has a switch arm (2) pivoted at one end inside a slot (5) and carrying the moving contact (3) at its other end. The contact end of the arm is moved across towards the fixed contact (14) by a hemispherical cam (7) rotated through 90 deg. by the breaker operating mechanism. The contact end of the arm acts against a helical spring (11) which tends to break the connection between contacts against the opposing action of the rotating cam. In its OFF position, the arm lies along the straight edge of the cam, and the moving contact is clear of the fixed contact. In its ON position, the cam has rotated through 90 deg. and forced the arm across so that the moving contact mates with the fixed contact.

Title: Bottle cap crimping machine - has spring cap limiting downward movement of plunger towards bottle
IPC: B67B3/14
Filed: 1974-05-03
Abstract: The machine is for use with bottles of plastic or light glass, having a crimping head adjustable for height on a column and with a plunger moving up and down and bearing against the top of the cap and also carrying a metal ring. A tubular component moves downwards round the ring to crimp the cap skirt against the bottle neck. The actuating mechanism is mechanically coupled to the tubular component and downward movement of the latter is transmitted via a compression spring to a piston carrying the plunger and the crimping ring. Downward movement of the piston is limited by a cap driven downwards by a spring until it strikes the crimping head mounting. After this further downward movement of the tubular component transmits no more effort to the piston and plunger, which are held back by the cap.

Title: Spanner for tightening and releasing bolts - socket head rotated by manually deflected curved leaf spring
IPC: B25B13/46
Filed: 1974-06-25
Abstract: A spanner for positions having restricted access which requires no reciprocal handle (6) motions during operation uses the reactions created by deflection of a pinned (2, 3) curved leaf spring (1) to rotate the bolt head, the spring being pinned to the handle (6) and a sleeve (7) mounted rotably within the head at the extremities (3, 2). The sleeve houses a uni-directionally rotated nut head engaging ring (8), the spring being deflected by the operator's hand (flattening the spring against the handle) and untightened by sequential deflections and relaxations of the spring. The eccentric connection of the spring to the sleeve provides a crank handle effect and the user's hand can be applied at mid-spring height.

Title: Fluid flow powered generator - has planetary vanes partially rotating to reduce drag
IPC: F03D3/06
Filed: 1974-07-12
Abstract: The four vanes (P) are carried on a central shaft (A) which has four radial arms. Each vane is geared to the central shaft by means of an increasing gear so that for every rotation of the central shaft (A) the vanes only make half a turn in the opposite direction of rotation to that of the shaft (A). In this way the vanes take up the positions shown which means there is no resistance to flow while the vanes are moving up stream (position 6). The vanes may operate with any fluid with any direction of flow and with any change of direction.

Title: Dry lettering contact transfer sheet - has a release layer between lettering and transparent carrier film
IPC: B44C1/17
Filed: 1974-09-24
Abstract: The construction of a transfer sheet, for the application of lettering by contact and pressure, uses a transparent carrier film of polystyrene, polystyrene butadiene or polyethylene terephthalate and an adhesive pigment for the lettering, held to the carrier by a release layer. The construction eliminates the need to apply a contact adhesive material over the whole transfer sheet so that letters are only transferred when pressure is applied to the individual letters, without the risk of adjacent letters or partial letters being transferred.
Patent FR-2252422-A1 (FR)
IPC: C25C1/06
Filed: 1974-11-25
Abstract: Iron is extracted by cathodic deposition from final pickling solutions which per litre contain at most 100 g of sulphuric acid and at least 25 g of iron ions. The sulphate ions are removed electrodialytically. Salts are added to the final pickling solution to set an ammonium, magnesium or alkali metal sulphate concentration of 0.5-1.0 mol/litre. The final pickling solution is fed into the cathode compartment of an electrolytical appliance composed of cells - which contain anode and cathode compartments separated by diaphragms - and is allowed to flow through said cathode compartments, while the iron content of the solution is depleted to a value of 7-15 g Fe<++>/litre. Then the solution is passed into the anode compartment of the appliance and is moved therethrough in a direction identical to that of the flow maintained in the cathode compartment. The current density based on the area of the diaphragm is held at a value of 15-22 A/dm<2>, and the operating temperature of the electrolysis is held at a value of 70-90 DEG C.
