Title: Improvements in and relating to the art of electric arc welding
IPC: B23K9/022
Filed: 1935-01-07
Abstract: 451,582. Arc welding. HUME, W. R., and HUME STEEL, Ltd., Kinnear House, King Street, Melbourne, Australia. Jan. 7, 1935, No. 564. [Class 83 (iv)] In a method of electric arc welding the molten metal formed beneath the electrode is caused to reciprocate or oscillate along the line of the joint being formed. The workpiece 6 which may be a pipe, the longitudinal seam of which is to be welded, is mounted on a support 18 fastened by pivoted lugs 16 to a screw-traversed carriage 13. A motor 19 mounted on the carriage operates a crank and slotted lever device for reciprocating the support 18, a lost motion coupling 32 is provided to give a lag in the return motion of the support and a stop 29 gives it a jerk at the end of the high-speed forward movement. The effect of this motion is to bank up the molten metal on the welded side of the crater and allow the arc from the stationary electrode 7 to penetrate the exposed workpiece. A modification for welding circumferential pipe-seams is described.

Abstract: 1,062,271. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. Jan. 8, 1965 [Jan. 8, 1964], No. 933/64. Heading B7K. An air cushion vehicle for operation over water has rigid sidewalls (3) (Fig. 1, not shown), an inflatable rear wall (4) and a set of transverse rollers (7) at the front of the cushion space, which is constructed as a plenum chamber and fed with air through ducts (17) from blowers (15). The rear blower inflates member (4) through a duct (17g) and a duct (18) leads air from the front blower to nozzles (10) which blow air over the forward surfaces of rollers (7), the air adhering to the surface of the rollers by Coanda effect to issue from the base of the rollers as a gaseous curtain. The rollers, which may be arranged in V formation, are carried by an axle (8) supported by springs (22) (Fig. 4, not shown) for deflection within a housing (21) formed in the structure (1). The rollers are of flexible construction and are inflated by pressure air led through the axle (8). They may be formed as two concentric cylinders, the concentric cavities thus formed being inflated to different pressures. The nozzle (10) may be carried by the roller mounting for vertical movement therewith. The rollers may rotate freely or they may be driven, mechanism for this and for controlling the supply of air to the rollers being described. Peripheral ribs which may be inflatable and may carry paddles may be formed on the outer surface of the rollers.

Title: System ensuring controlled release of active ingredient and process for the production thereof
Inventor: WENZEL UDO
IPC: C05G3/40
Filed: 1990-01-30
Abstract: The invention relates to a system for the controlled release of active agents and a process for its preparation, preferably an orally administrable pharmaceutical preparation for various, especially soluble, pharmaceutical agents, having even, controlled active agent release essentially caused by convective processes. The system of the invention is similar in therapeutic effectivity to an intravenous drip, i.e. the even and complete release of the active agent from the pharmaceutical preparation for a physiologically and therapeutically practical period of time caused by essentially convective processes. This leads to a constant therapeutic blood level which guarantees the long-term effect of the drug whilst reducing the adverse effects and improving local tolerance in the gastrointestinal tract at the same time. Furthermore, with the composition according to the invention of the pharmaceutical preparation and the preparation process according to the invention, damages to the shell controlling the release of the pharmaceutical agent will not lead to dose-dumping, as is usually the case in membrane-controlled pharmaceutical agent release, and the preset release rate will be reached within a short period of time.

Title: Single-use syringe
Inventor: SERRANO GONZALEZ ANTONIO
IPC: A61M5/315
Filed: 1990-07-25
Abstract: The syringe is comprised of an external cylindrical body (1) and a suction and ejection piston (2) displaceable within said body, the piston including at its internal end the corresponding seal (3). According to the invention, said seal is held at the extremity of the piston by means of one or a plurality of arms (4) hinged at said end of the piston, said arm or arms traversing the side wall of the seal to retain the latter. The arms have a sharpened free end (6) and a cutting front edge (7), so that, during the advance movement of the piston during the ejection phase, the wall of the external cylindrical body is cut, no cut being done during the suction displacement. The syringe is disposable and not reusable after its first and single use. <IMAGE>

Title: Manufacture of rod lens
Inventor: YANAGAWA HISAHARU
IPC: G02B6/00
Filed: 1980-01-07
Abstract: PURPOSE:To obtain a ripple-free rod lens having an optimum refractive index distribution by forming a preform rod so that the refractive index distribution parameter is made larger than a specified value, heat treating the rod, and adjusting the parameter to the specified value. CONSTITUTION:When a preform rod for a rod lens is formed, refractive index distribution parameter alpha in the equation [where n1 is the refractive index of a central part of the core, n2 is the refractive index of the clad, A is the diameter of the core, r is the distance between the center of the core and the outside periphery of the core, and n(r) is the refractive index of the core] is made larger than a predetermined value. By heat treating the preform rod at a high temp., the refractive index distribution curve is smoothened to prevent the occurrence of ripples. At the time of this heat treatment, parameter alpha becomes smaller but is larger than the predetermined value, so by the treatment parameter alpha is made smaller and adjusted to the predetermined value.

Abstract: PURPOSE:To grow the titled single crystal capable of slicing a substrate wafer having zero temperature coefficient at room temperature in good yield, by setting the growth axis direction of a seed crystal at <210> direction in a growth method for the titled single crystal by the Czochralski process. CONSTITUTION:A seed crystal is dipped in a raw material melt in a crucible and Li2B4O7 single crystal is grown while rotating the seed crystal by the Czochralski process. In the process, pulling up is carried out in <210> direction while rotating the growth axis of an Li2B4O7 seed crystal by lambda=26.6 deg. expressed in terms of an Eulerian angle. When the seed crystal is used to grow a single crystal, a face perpendicular to the grow a single crystal becomes the (210) face, i.e. 26.6 deg. X plate Z propagation face. Thereby the titled single crystal capable of slicing a substrate wafer having zero temperature coefficient at room temperature can be grown in good yield.
