Title: Improvements in or relating to a hinge, in particular for an automobile vehicle door
IPC: E05D7/10
Filed: 1967-05-05
Abstract: 1,144,675. Vehicle door hinge; knuckle joint. AUTOMOBILES PEUGEOT. 5 May, 1967 [13 May, 1966], No. 21001/67. Heading E2F. A knuckle jointed hinge for mounting a motor vehicle door has a ball element 7 attached to the lower eye 1 of the bifurcated hinge component L<SP>1</SP> by means of a stem 6 which is a tight fit in the eye. Alternatively the ball element may be welded to, or integral with the lower fork of the said component. The other hinge component, L<SP>2</SP> has an eye 9 which is downwardly offset towards the ball member and which is internally stepped; this eye carries an externally stepped cylindrical member 14, suitably of machined oil-impregnated sintered steel, having in its lower end face a part spherical cavity 15 of the same radius as the ball. The upper part of the member 14 projects beyond the face 16 of the eye 9, as a shoulder 17 terminating in a spigot 18. A resilient element E is situated between the eye 9 and the lower face of the upper eye 2 of the bifurcated component, this element being of spring steel strip bent to form a U, of which the branches are of unequal length, the shorter branch is bent in to form a flange which limits the extent to which the branches can be inwardly deformed. The shorter branch and its flange have a central open ended slot (not shown) whose width equals the diameter of the spigot, and the other branch has a central boss 25. On assembly of the hinge, the cavity 15 situated on the ball 7, the three eyes of the hinge components are axially aligned, and then the resilient member E positioned astride the spigot and driven into the clearance between the central and upper eyes until the boss 25 engages the aperture 4 in the upper eye, with partial elastic flattening of this member. The resilient member is prevented from rotating by a chamfered face 8 of the hinge part L<SP>1</SP>, which bears against one side of the member. In an alternative embodiment the member E is replaced by a helical spring engaged at each end in cavities in dished washers. There is no spigot 18 in the aperture in the eye of the inner hinge component, and each washer has a central boss to engage an upper or lower eye. The dished parts of the washers axially abut one another on excessive compression of the spring, to prevent accidental disengagement of the bearing members. The outer panel of the vehicle door A is extended at e to conceal the hinge when the door is closed.

Title: Process and apparatus for decontamination of milk products by electrodialysis
IPC: B01D61/44
Filed: 1963-05-29
Abstract: <PICT:1005125/C6-C7/1> Radioactive ionized contaminants are removed from milk by D.C. electrodialysis in a cell having between end electrodes two or more repeating units each comprising three compartments, the centre compartment being bounded on both sides by ion-exchange diaphragms of the same selectivity and the compartments adjacent thereto being defined on their outer sides by an ion exchange diaphragm of opposite selectivity to those bounding the centre compartment, the contaminated milk being passed through the centre compartment while electrolyte solutions are passed through the adjacent compartments whereby the milk leaving the centre compartment is of reduced radioactive content due to the radioactive ions having migrated into one adjacent compartment while ions from the other adjacent compartment migrate into the centre compartment to replenish the normal non-radioactive mineral salt content depleted by migration of ions from the centre compartment simultaneously with the radioactive ions.  As shown, for removing strontium 90 from milk, the milk which is brought to pH 4.8-6 with citric acid, is fed into the centre compartment 2 of a 5-unit cell, compartment 2 being bounded by cation exchange diaphragms K1 K2, and a solution of pH 6 containing Ca, Mg, Na, K and Cl ions is fed through compartment 3, while waste compartment 1 which initially contains an electrolyte is thereafter fed with water.  The effluent decontaminated milk is brought to pH 6.6 with aqueous potassium hydroxide.  If milk deficient in sodium is required this is omitted from the feed to the reconstituting compartment 3, while in place of adding citric acid to the contaminated milk this may be made acid by suitably acidifying with hydrochloric acid the reconstituting compartment 3.  In a modification, Fig. 2 (not shown), the centre compartment is divided by a microporous diaphragm as of rubber, asbestos, ceramic, polyvinyl chloride, polythene, the milk entering on the cathode side of the diaphragm and flowing under hydrostatic pressure through the diaphragm against the movement of the cations but at a slower rate and being removed from the compartment on the anode side of the porous diaphragm.  Iodine 137 may be removed by defining centre compartment by anion exchange membranes and supplying the reconstituting compartment with a solution containing phosphate, citrate, sulphate and chloride anions with sodium cations.  Common inlet and outlet manifolds for all the conduits handling the same liquid may be provided connecting a series of cell units such as above described, the liquid being fed to the different units in series or parallel and different liquids passing through the cell units in the same or opposite directions.  Milk to be treated may be fed batchwise through the same decontaminating compartment several times to reduce its level of contamination to the desired value. Specifications 720,002, 772,861, 772,862, 792,623 and 821,229 are referred to.

In a camera having a reflex viewfinder the focus is checked by a device comprising two small reflecting surfaces spaced apart in a direction perpendicular to the optical axis of the camera objective so that the two images formed are superimposed when the camera is correctly focussed. As shown, the device comprises a glass block divided into three parts L 1 , L 2 , L 3  which are cemented together. The optical axis XX<SP>1</SP> of a camera passes through the face between L 1  and L 2  which face makes an angle of 45 degrees with the optical axis and carries two small reflective surfaces.A, B. The face between L 2  and L 3  carries a semireflecting portion D. Light reflected from A passes through the semi-reflecting portion D and light reflected from B is reflected at a surface C, parallel to the face between L 2  and L 3 , on to the semi-reflecting portion D where it is again reflected and travels along the same path as the light reflected from A. The path AD is equal in length to BD and CD so that points in the two images coincide when a lens placed in the path of rays reaching the device is properly focussed. The device may be used in a camera viewfinder the optical system of which is illustrated in Figs 9 and 10 (not shown) and of which optical data is given. In a modification, Fig 7 (not shown) the semi-reflecting surface may be replaced by a surface having some transparent and some totally reflecting areas.
