Title: Method and apparatus for building up surface layer having portions of different compositions
IPC: B23K35/30
Filed: 1980-07-02
Abstract: The method consists in that two or more materials to form alloys are fed to a weld pool and the ratio of these materials is varied at the moment of transition from a section of one composition to a section of a different composition in such a manner that the length of the transition zone is minimized. The time of transition is determined by the volume of the weld pool, rate of surfacing, cross section of the layer being formed, and amounts of alloying elements. The apparatus for carrying out this method includes a surfacing parameters regulating unit 1, a programmer 2, a comparator 3, an adder- differentiator link 4, voltage limiter 5, a switching device 6 and an a periodic link 7. The latter is a simulator of the weld pool, is connected to a control device 8 controlling a device 9 for feeding alloying materials and through the switching device is connected with the voltage limiter 5. <IMAGE>

Title: Endoprosthetic bone joint devices
IPC: A61F2/30
Filed: 1980-08-12
Abstract: Endoprosthetic metacarpal phalangeal joint devices are well known in various forms including unitary flexible structures for connection between the bones, and others with separate phalangeal (12) and metacarpal components (13) for respective bone connection and inter-engagement or connection for mutual articulation in a hinge action. All such devices are applied individually to respective joints and can tend to fail due to conditions leading to ulnar drift. It is now proposed that this tendency be obviated by mechanically interconnecting a plurality of devices of the latter form in the hand, suitably by use of a common hinge axle 14. The axle preferably has slight longitudinal curvature to pass through the natural joint centres. The phalangeal components (12) preferably each have a socket (20) for bone connection and a stem (16) for axle connection, the stem being slidably and rotatably received in the socket to accommodate torsional loading. <IMAGE>

Title: Key holder
IPC: A44B15/00
Filed: 1980-10-20
Abstract: A key holder has a rigid gapped ring 1, having a gap which is defined between two mutually facing tips, a thin-walled metal sheath 2 having, near one end, two transverse slots or apertures of asymmetric form permitting the transverse introduction of the tips 4 of the ring 1 from one side only of the sheath 2, i.e. the front side as seen in the drawing, and a slide 3 which is longitudinally slidable inside the sheath 2 and comprises at the position of each of the apertures 5 locking ribs situated on that side of the apertures 5 from which the tips 4 are introduced.

Patent GB-819197-A (GB)
Abstract: 819,197. Electric condensers. STEATITMAGNESIA A.G. Nov. 14, 1957 [Nov. 16, 1956], No. 35522/57. Class 37. A variable (e.g. a wobbulation) condenser comprises two or more electrically connected condenser sections, each including a rotor and stator, at least one section being such that the relative position of its rotor and stator may be varied independently of the other sections so that the " stroke " or extent variation in the capacitance can be continuously varied while the mean capacitance remains substantially constant. In the embodiment shown, one set of stator plates 8 is fixed but the other set 2 is adjustable graphs being given (Figs. 2 and 4, not shown) to show the variation in capacitance with the stator plates 2 in the positions shown in Fig. 1 and at right angles thereto (Fig. 3, not shown). The rotors may, as shown, be of ceramic provided with semicircular metallic coatings 1 or with metal foil electrodes and the stator plates may be of metal or metallized ceramic. Alternatively, the stator plates could be fixed and the rotors displaced angularly with respect to one another by dividing shaft 3 into two. A potentiometer may be mechanically coupled to the rotatable stator so that the potentiometer wiper is actuated by rotation of the stator, the potential obtained from the tapping being of an amplitude and variation which are proportional to the amplitude and variation in the capacitance. The tapped voltage can be used as a control voltage to effect compensation to the " wobbulation " curves of the graphs (not shown). Other control devices, e.g. a mechanical-electrical indicator may be connected in place of the potentiometer to indicate adjustment in the " stroke " or for remote control of another, similar condenser. Further, a variable condenser may be connected to the rotatable stator plates to provide for alteration in mean frequency in dependence on the stroke. Two or more such condenser units may be combined to form a multiple unit, the adjustment of stroke of the multiple unit being varied continuously, as desired in the individual units either separately or simultaneously by means of a mechanical connection or by electrical control. If an individual electric drive is provided for the rotor of each unit, this may be by several electric motors which can be fed as synchronous. machines from a common A.C. source.
