Abstract: For automatically drilling boreholes within halving joints and frame portions of lattice windows, ejecting glue into said boreholes and inserting dowels, units are proposed, which consist of three dowel inserting devices and three associated glue injecting devices each being operable individually and simultaneously, and which are arranged according to the borehole pattern within the face of a halving joint. For disposing the dowels in magazines and for inserting said dowels into the boreholes in a controlled manner changeable magazines are proposed the bottom of which is arranged above a dowel receiving head and the dowel discharge location is associated to the receiving locations of the dowel receiving head; in this position dowels are transferred into the recesses of the dowel receiving head and are arranged in the discharge position from which they are inserted by means of dowel ejectors into aligned boreholes of a workpiece.

Abstract: A dietary supplement formulated to suppress appetite comprising L-phenylalanine in combination with restricted quantities of protein, carbohydrate, fat and dietary fiber.

Abstract: This invention relates to a system for automatic performance of agricultural tasks such as lawn mowing. It comprises in combination a guide rail (2; 110) more or less buried in the ground, and an agricultural vehicle such as a lawn mower, provided with a support frame (6; 101), with at least one tool such as a cutting bar (8, 16a, 16b; 102), drive means (4a, 4b, 5a, 5b; 103, 104a, 104b) and guide means (27, 29; 106, 108) mounted movably on said support frame and designed to work with said guide rail to cause said vehicle approximately to follow the guide rail.

Abstract: An outdoor lighting controller including a light sensing element for automatically activating and de-activating an outdoor light source. A wiper is provided for removing accumulated dust from the light sensing element. The wiper is initiated when the light source is activated.

Abstract: A motor vehicle lift comprising in combination:a pair of base longitudinal members (1) for its support on and/or securing to the floor,a pair of first uprights (2) hinged lowerly to said longitudinal members (1),a pair of second uprights (4) hinged lowerly to said longitudinal members (1) and upperly to said first uprights (2) at an intermediate point thereof,a pair of vehicle lifting runways (6) hinged to the upper end of said first uprights (2) and formed in several separate parts which are kept substantially aligned when the lift is lowered,a pair of actuators (17) acting so to vary the reciprocal contained angle of said pairs of first uprights (2) and second uprights (4), for raising the lift, anda pair of members (15,15') interposed between said first uprights (2) and the portion (8) of runways (6) hinged to said first uprights (2) to check their reciprocal contained angle during the raising of the lift,the hinging between a pair of said uprights (2,4) and said longitudinal members (1) being of such a ty

Abstract: A sighting device for aiming an astronomical telescope. The sighting device comprises a tubular housing which is removably mountable in the eyepiece holder of the telescope. A light source is mounted within the tubular housing for projecting light into the eyepiece holder to thereby form a beam of light emergent from the front end of the telescope. This beam of light provides a visual indication of the direction in which the telescope is aimed, and the telescope may be aimed at a desired object or area by reference to the beam of light. After the telescope has been aimed, the sighting device is removed and replaced by a normal eyepiece.

Abstract: Disclosed herein is an adapter for rendering an earth mover amphibious, comprising a buggy assembly having a pair of buoyant pontoons and tracks that are driven around the pontoons by hydraulic motors situated coaxially with drive sprockets for the track. The track is driven by the motor without an intermediate chain drive, thus avoiding certain environmental and personal dangers.

Abstract: A thermostatically controlled electric heater for aquariums includes within an electric waterproof envelope, a heating element and a working unit regulating the temperature, moving axially in order to vary the rest position of a bimetal strip which, depending on its deformation, opens and closes the supply circuit of the heating element. The regulation unit (3) is provided with a threaded pin (13), the end resting against the bimetal strip (7) and with a cylindrical body (11), provided on the side surface with a helical line (12) dividing the surface of the cylindrical body into two differently colored portions (12) covered by a screen (18) provided with a longitudinal slot (19) through which a short portion of said helical line (12) is visible. A grauated scale is provided along the slot and cooperates with the visible portion of the line to indicate the set operating temperature of the heater.

Abstract: A fixture for holding workpieces at predetermined angles while they are being interconnected includes a pair of legs and a hypotenuse forming a right triangle, whose three vertices are truncated to enable the fixture to function as a jig, as a template, or as a bending tool. Workpieces may easily be attached to the fixture, obviating the need for special clamps.

Abstract: A machine for felling and shaping trees is provided with a work head susped by at least two perpendicular joints one of which makes possible its horizontal swivel and the other a certain angular freedom in the vertical plane and carried by a frame consisting of a beam comprising at least a free space intended to neutralize the joint of vertical angular freedom in felling position.
