Abstract: A device for sealing wrapping material on pieces of candy or similar products, in what is known as the "soap" style of wrapping, and for exiting the products, in their sealed wraps, from the wrapping machine. Each wrapped product is first received in a correspondingly dimensioned pocket of a horizontal conveyor disk, which intermittently conveys the product along a sequence of plates, comprising a presser plate, a first heat-welding plate, and a first cooling plate. The presser plate eliminates bulges of the sides of the product, created during the wrapping. It presses other sides of the product, with folded tabs of the wrap thereon, into the pocket. The heat-welding plate then seals portions of the wrap on a then exposed side of the product.

This composition contains co-agglomerates of finely-divided particles of a normally non-dispersible material and a silicon dioxide flow agent having a thin coating of edible fat. The composition may optionally include flavorants and other additives.

Abstract: A solar energy collecting system, which may be operated to provide usable energy throughout the year, comprises a plurality of rows of elongate radiant solar energy collecting panels, each having upper and lower edges, being mounted to form an angle to the horizon and to face the sun's position at solar noon. An elongate reflector, also having upper and lower edges, compliments each row of collector panels to reflect radiant solar energy to it. The upper edge of each row of collector panels is positioned adjacent the upper edge of a reflector to define a single, inverted, generally V-shaped peak. The lower edge of each collector which forms a part of one peak is spaced from the lower edge of the reflector which forms a part of an adjacent peak to define a valley. A walkway is constructed in each valley to provide access to both the reflectors and collector panels for drainage and maintenance.

Abstract: An extrusion nozzle, especially suitable for texturing proteinaceous materials, comprising an elongate body having a side wall defining an axial passage, at one extremity of the body the side wall having longitudinal slits defining at least two fins the free ends of which are turned inwardly towards the longitudinal axis of the passage. Other features of the invention are described in the following specification.

Abstract: Device for actuating and controlling the movable bottom of a refuse collection or like body, notably in a refuse collection vehicle and for improving the performance of the main functions of such body or vehicle, by providing a uniform compression of the refuse within the body and ensuring a more reliable operation under recompression and ejection conditions, while eliminating the risk of wrong manoeuvres. This device comprises a telescopic-type hydraulic cylinder and piston actuator controlling the movements of said movable bottom, namely the compression of refuse and the development of a retaining force during the ramming of the refuse by the ramming means incorporated in the hinged door at the opposite end of the body. To this end, an automatic valve is interposed in the hydraulic circuit controlling said movable bottom, said valve remaining close as long as the pressure exerted by the refuse ramming means or the pressure exerted by the refuse against said bottom remains below a predetermined value.

Abstract: A printing device for printing with drops of printing fluid, in which discrete droplets of a printing fluid are ejected from a printing element along a predetermined path to a recording surface. The printing element comprises a nozzle communicating with a printing fluid reservoir. A control electrode mounted on the nozzle is arranged to apply pressure pulses to printing fluid in the nozzle so as to eject discrete droplets of printing fluid from said nozzle.

Abstract: A crystal-controlled oscillator whose frequency is regulated as a function of temperature and having a feedback loop with a capacitor whose capacitance is electrically variable, to which capacitor a variable electrical compensating signal varying in accordance with a third-degree law as a function of temperature, is applied. The compensating circuit in accordance with the invention produces a signal of this kind at its terminals by three units respectively comprising three thermistors R.sub.T1, R.sub.T2, R.sub.T3, each unit being specifically designed to create the signal corresponding to a given arcuate portion of the total graph function.

Abstract: A scintillation camera is suspended from an elevated gantry and is laterally movable. Sensors detecting the lateral position of the scintillation camera detector head produce signals which are combined with the detector head output signals to produce an image reflecting the occurrence of radioactive events within an expanded rectilinear field of view of the detector head. This image is stored using a recording medium.

Abstract: High-frequency waves transmitted by a rotating antenna array at a ground tion are intercepted by an airborne receiver for photoelectric evaluation by one or more discs whose light transmissivity, by translumination or reflection, varies periodically according to a sinusoidal law in one diametral direction while being constant in another diametral direction orthogonal thereto. The disc or discs are rotated at a speed corresponding to that of the transmitting antenna array, under the control of periodic synchronizing pulses, and are illuminated by a flux modulated by an electrical signal derived from the incoming wave, this signal containing a phase component dependent on two spatial coordinates such as elevational and azimuthal angles determining the relative position of the ground transmitter and the airborne receiver.

Abstract: A characteristic message exchange procedure is performed by a set of contler units at separate stations and of functionally identical design. The combination of a controller unit and a utilization unit that characterizes the application of the station constitutes a complete station. Among other things, the controller units provide sequencing of the transmitting privilege among the stations one by one. All message data are classified into four basic message models representing the applications of the stations. The stations are interconnected by a single common transmission channel and the controllers are equipped to be sensitive to only four basic message models. No central control unit is required for monitoring transmissions between stations. All active stations receive all messages essentially simultaneously.

Abstract: A method for improving adhesion of nonfogging film coatings comprising a block copolymer containing alternating blocks of polyurethane and a hydrophilic polyacrylic, to a polymeric substrate by subjecting the substrate to a controlled exposure to UV irradiation. Exposure may be prior to or following casting the nonfogging coating in place on the substrate. By varying the weight ratio of polyurethane/polyacrylic it is possible to vary the flexibility of the coating and hence to widen the range of substrates to which the coating may be applied, e.g., from flexible wrapping material to rigid mirrors.

Abstract: The reed contact unit comprises a pair of aligned members of magnetizable and electrically conductive material spaced apart endwise from each other with a fillet of non-magnetic electrically conductive material inserted between the spaced ends of the members. The upper surfaces of the members and the fillet are coplanar. An electrically conductive cantilever carries an electrically conductive and magnetizable armature at its free end overlying the fillet and the adjacent ends of the members. Upon magnetization of the members, a contact surface of the armature contacts the members to complete an electric circuit between the cantilever and the members. The members and the cantilever are mounted within a hermetically sealed enclosure.
