Patent EP-0223861-A1 (EP)
Inventor: OBARA HARUKI
IPC: B23H1/02
Filed: 1986-05-29
Abstract: A power source for discharge machining, which electrically charges a capacitor (C1) that is connected in parallel with an electrode (P) and a work (W), and which applies a charging voltage (VC) across the electrode and the work, so that there takes place an electric discharge to perform the discharge machining. The power source for machining quickly charges the capacitor. Besides, it is tried to construct the power source at low cost and improve the power source efficiency. A charging circuit of the capacitor (C1) includes a switching element (T1 ) which can be turned on or off to connect the capacitor to a d-c power source (E) to electrically charge it. The charging circuit is further provided with a fly-wheel circuit which consists of an inductance (L1 ) and a diode (D1). An inverse voltage produced by a stray inductance (L2) in the discharge circuit during the discharge is applied as a forward voltage to the capacitor through the fly-wheel circuit.

Abstract: A polymer lactide is prepared by the polymerization of meso-3,6-­dimethyl-1,4-dioxane-2,5-dione or mesodilactide and, if desired, other monomers. The mesolactide monomer has preferably a free acid content of less than 1 meq/kg dilactide and is then polymerized in a manner known per se. The compositions containing polymesolactide obtained according to this process do not posses the typical characteristics of poly-DL-lactide, poly-D-lactide or poly-L-­lactide. A shorter degradation time of a substrate based on the present polymer is unofficial for several purposes. The present polymers have a good biocompatibility and are thus suited for bone plates, clamps and sutures and controlled release of biologically active compounds. The present polylactides and/or copolymers there­of have the benefit of a good biodegradability, biocompatibility, non-toxicity and non-mutagenicity.

Abstract: Metal-ceramic joined composite bodies each comprise a metallic member (14) and a ceramic member (11) integrally joined together by joining a projection of the ceramic member (11) to a recess of the metallic member (14). Their joining strength is improved by appropriately selecting joining site and way between the metallic and ceramic members, and/or shapes thereof, e.g., by substantially limiting brazing metal-joining to an interface between the outer peripheral surface (18) of the projection of the ceramic member and the inner peripheral surface (19) of the recess of the metallic member. The joining strength is also improved by forming a groove around the substantially entire outer periphery of the metallic member corresponding to a joining end between the metallic and ceramic members. The joining strength is also improved by avoiding firm chemical joining between the brazing metal and the ceramic projection at at least the joining end, or by providing a space or an intermediate member between a tip end surface (13) of the projection and a bottom surface (16) of the recess and attaining the relation: 
  
     > (α - α′) × (T     S      - T     R     )   
 
in which G, L₁, α, α′, T S  and T R  are the thickness of the space or the intermediate member, a distance from the bottom surface of the recess of the metallic member to the joining end, a coefficient of thermal expansion of the metallic member, a coefficient of thermal expansion of the ceramic member, a solidifying temperature of the brazing metal, and room temperature, respectively. The joining strength is also improved by radially enlarging the recess near the opening, brazing the outer peripheral surface of the projection and the inner peripheral surface of the recess, and thinning the brazing metal toward the opening of the recess beyond the enlargement-beginning location of the recess. Processes for obtaining the metal-ceramic joined composite bodies are also disclosed.

Title: Security gate operable with one hand
Inventor: STERN CARL M
IPC: A47D13/00
Filed: 1988-09-19
Abstract: A security gate includes an installation and release mechanism that is operable with one hand. The gate comprises two panels (22,24) which are extendible with respect to each other and lockable in the extended position. This makes it possible for the gate to expand across a wide variety of door openings. A handle (36) located centrally on the top of the gate is connected by a pair of cranks (56,88) and a pull rod (76) to a pair of plungers (26,28) which contact one side of the door frame. Spring bias (66,104) on the plungers normally force the plungers into contact with the door frame. Slots (64,98) in the upper and lower plunger links permit the plungers to accommodate irregular door frames. The handle is employed to withdraw the plungers from contact with the door frames and, conversely, the absence of handle pressure causes the gate to position itself solidly against the vertical door jamb. The handle is also employed by the operator to carry and position the gate in the doorway, allowing one-handed operation. A thumb operable handle interlock system prevents the handle from being accidentally manipulated unless one of two release interlock buttons (38) is depressed by the thumb of the user. Also, the two extended panels are held in position by a second safety interlock which prevents a pair of extension adjustment knobs (32) from rotating unless the extension interlock is released.

Abstract: The control system for the rotation of a turntable (T1) comprises an interferometer whose measuring arms include trihedra in the form of glass cuneiforms (P1, P2) fixed to the turntable (T1). For small rotations of the table (T1), these cause the light they receive from a source (S2) always to be reflected in the same direction. A doubly refracting plate (LB) is placed in one of the arms and two receivers (R1, R2) receive the light from the interferometer through analysers (A1, A2). This enables displacements of the cuneiforms (P1, P2), and hence rotations of the table (T1), to be detected. The invention applies to an X-ray spectrometer. <IMAGE>
