Abstract: A toy baseball pitching machine that is particularly adapted to be used by children. The machine has a ball pitching arm that oscillates rather than rotates and is capable of pitching a plastic ball to a batter using an "underhand" method of pitching. The ball pitching arm is fixed to an oscillatable eccentric arm. The eccentric arm is connected to one end of an extension spring, and the arm carries a pivoted pawl. The pawl is engaged by a toothed rotating drive wheel to rotate the pitching arm in one direction toward a cocked position with the spring extended. Further rotation of the drive wheel brings the pawl into contact with a stop to pivot the pawl out of engagement with the drive wheel. The extended spring then acts on the eccentric arm and pitching arm to rotate the pitching arm in the opposite direction to engage and pitch a ball. The drive wheel, pawl, eccentric arm, stop and extension spring are all mounted within a housing; and the pitching arm is outside the housing.

Abstract: A connector unit, which comprises an insulating housing carrying a plurality of connection pins planted therethrough and accommodating a dielectric plate formed with through-holes penetrated by the connection pins and provided on both sides with electrodes. Thus, a capacitor is connected between each connection pin and earth, so that the connector unit is capable of preventing external interference waves from being introduced through the connection pins into the electric apparatus and also preventing spurious waves generated within the electric apparatus from radiation to the outside through the connection pins.

Abstract: A method for the erection of a temporary bridge, etc.

Abstract: An earthquake isolation floor comprises a horizontal plate-like support frame having a generally circular or polygonal configuration, a support frame having a horizontal surface with a similar configuration to that of the fundamental frame in a plan view, but of relatively smaller dimensions, a number of horizontal springs disposed radially between the fundamental and support frames with each of the springs being kept in a preset state, and a number of horizontal dampers disposed radially between the fundamental and the support frames, whereby machinery and tools, etc. to be protected against vibration such as caused by an earthquake are adapted to be mounted on the support frame.

Abstract: In accordance with illustrative embodiments of the present invention, techniques are shown for processing well logging data to provide improved results. More particularly, a technique is disclosed for determining the reliability of well logging computations. Another technique is disclosed for making a preliminary pass of the well logging data to automatically select certain input parameters. Still another technique is disclosed for automatically determining the minimum possible hydrocarbon density for each formation level. This last technique is contrasted with the prior art technique which set one minimum value for the entire length of a borehole.

Abstract: A protective circuit for a class B OTL circuit such as a vertical deflection circuit and a sound output circuit of a television set. The protective circuit comprises a first voltage comparator circuit having one input terminal applied with a detection signal in the form of an average voltage of an output signal of the OTL circuit and the other input terminal applied with a first reference voltage, and a second voltage comparator circuit having one input terminal applied with the detection signal and the other input terminal applied with a second reference voltage which is different from the first reference voltage. Either one of the voltage comparator circuits is operated when the output terminal of the OTL circuit is short-circuited to either the power supply voltage line or earth.

Abstract: An improved thermal insulation material comprising a carded web containing 30 to 80 wt. %, preferably 50 wt. % silk, the balance being crimped, hollow polyester staple or very low denier solid cross section polyester filaments. The carded web is uniformly impregnated with a thermosetting resin to form a bat which is employed as a filler for garments, sleeping bags and the like.

Abstract: An ejector for firearms which use projectiles without cases of the new design with a perimetric primer. Such an ejector may be used on any type of gun which is equipped with a radial percussion system designed to percuss such projectiles.Used with the projectiles without cases, the ejector should eject from the detonating chamber of the gun only those projectiles on which the firing pin has not provoked the detonation of the charge at the moment of percussion.At the same time since it is impossible to prevent from time to time during firing the occurrence of defective projectiles which remain in the barrel, during the phase of introduction into the detonating chamber the ejector should be able to hook onto every single projectile, retaining hooked onto it only those which, due to defects, remain in the detonating chamber and leaving all the others free to come out of the mouth of the barrel.

Abstract: A cable stripping tool for the stripping of sheathing from multi-conductor ribbon cable of various widths includes a blade mounted for the simultaneous slitting of the two longitudinal edges of the cable sheathing without damage to the enclosed conductors. A guide element projects forward from the blade to direct the blade into the cable between the sheathing and the enclosed conductors. In a particular embodiment, the blade has two cutting edges mounted at a 60 degree angle to each other to provide a self-aligning feature.

Abstract: A cam operated gripper driven by an endless chain receives at a feed station a wrapped straw having a heat-bondable portion and carries the straw to a bonding section. The gripper is associated with an electric heater which is in contact with the gripped straw. In the bonding section, an electric power supply rail is provided so that a collector of the heater slides on the rail, energizing the electric heater to heat the heat-bondable portion of the wrapped straw. In the bonding section, the heater is also pressed against the carton travelling in a production line at the same speed as the moving speed of the heater with the heat-bondable portion of the wrapped film therebetween. Thus one film wrapper is heat-bonded to each carton. After the completion of bonding, the cam operated gripper releases the straw allowing the straw to remain attached on the carton.

Abstract: A tourniquet constructed from a length of elastic material. The ends of the elastic material are made non-elastic, and complementary coupling components are attached thereto. The elastic material is provided with a thickening for stress absorption and control.

Abstract: An improved woven synthetic textile fabric is formed by using an entangled combination of a fibrillated slit film yarn and a multi-filament yarn as at least one of the warp and fill members. The fabric is characterized by the look and feel of a jute fabric and may be employed as a woven cloth to manufacture bags, bale wrap, wall covering, drapes and the like or, preferably, to produce secondary backing fabric for tufted carpets which exhibits enhanced adhesion characteristics as compared to prior art synthetic secondary backing materials.

Abstract: Disclosed in this invention is a recording medium characterized by forming on the support a recording layer containing a metastable sensitive substance which is an intermediate product of a reaction between a first colorless or light-colored material containing the S atoms released by light irradiation and a second colorless or light-colored material which develops color as it is sulfurized by said S atoms.

Abstract: A method and means for releasably rigidly fastening two standardized metal profiles intersected at an angle and lying one upon another are provided in which four L-shaped members each having two vertical sides are respectively applied at the respective corners of the intersection such that the outer faces of the respective sides of the L-shaped member abut against the respective edge portions of the metal profiles at the intersection lying one upon another and at the same time portions of the respective sides are made to protrude beyond the upper or lower surface of the metal profiles, whereby the confronting protruded portions of the sides of the L-shaped members are rigidly connected together by any suitable fastening means with the metal profiles being respectively interposed between the confronting sides, respectively.
