Title: Injection molding system with gas flow through valve gate
Inventor: GELLERT JOBST U
IPC: B29C45/28
Filed: 1989-07-19
Granted: 1992-12-29
Abstract: ABSTRACT OF THE DISCLOSURE         A valve gated injection molding system for making hollow plastic products.  A fixed pin extends through an elongated hollow valve member which is reciprocated between a retracted open position and a forward closed position in which the forward end of the valve member is seated in the gate.  The fixed pin has a hollow portion for the flow of pressurized gas to a porous portion at the forward end which is centrally located in the gate.  In the open position, gas from the fixed pin flows into the hollow center of a stream of melt which flows into the cavity around the forward end of the fixed pin to form a melt bubble in the cavity.

Abstract: ABSTRACT            A high strength metallic drum is disclosed having an high internal volume for given external dimensions. The drum is divided into annular top,  middle and bottom  drum  sections.    Each  drum  section  has  a constant diameter, with the diameters of the top and bottom drum sections being larger than the diameters of the middle drum section.  A pair of swedge rolling hoops  are  provided  at  the  boundaries  between adjacent sections to give the drum rigidity.  A first one of the rolling hoops joins the top and middle sections while  the  second  rolling hoop joins the middle and bottom sections.  Each swedge rolling hoop has a gripping surface that extends outwardly from the middle drum portion to facilitate handling the drum.   The maximum diameters of the swedge rolling hoops are larger than the diameters of each of the sections they join.   In a preferred 55 gallon drum embodiment, the top and bottom sections have the same diameter and the  swedge  rolling hoops are mirror images of each other.   The maximum diameter of the swedge  rolling  hoops are  in  the  range  of  three quarters of an inch to one inch greater than the diameter of the middle drum section.

Abstract: ABSTRACT OF THE DISCLOSURE An electronic package comprising dielectric layers including a densified aluminum nitride (AlN) base layer and at least one densified AlN-borosilicate glass composite layer bonded thereto is described.  Any of the dielectric layers may be metallized with conductive circuit patterns and can contain conductive vias. Production of this package is accomplished by hot pressing a greenware laminate comprising a densified base (e.g., AlN); at least one green sinterable sheet (e.g., AlN-borosilicate glass composite); and a green sheet of non-sinterable material (e.g., boron nitride [BN]).  The respective green sheets comprise homogeneous mixtures of the ceramic powders and a binder, e.g., polyethylene.  The polyethylene is burnt off during the hot press operation. Residual BN is removed by brushing and/or grit blasting, leaving the finished electronic package, all ceramic elements of which are densified.  The package provides superior thermal conductivity, strength, dielectric properties, and silicon-compatibility.

Abstract: A duplicate recording system uses video cassettes for storing master library recordings. On both the recording and the duplicating ends of the system, all signals are buffer stored in an electronic memory while the signals are in a digital form.      This buffer storage completely isolates the recording/reproducing steps so that the usual parameter of restraints disappear. For example, the duplication ratio may be any value within the capabilities of the recording/reproducing machines. This isolation eliminates expensive setup procedures heretofore required to switch from one to another duplicating ratio. The buffer storage also provides a more precise transfer with greater fidelity of the recorded signals. A computer calculates a smoother analog curve when the digital-to-analog conversion is made.

Date Aug. 29, 1985.The present invention relates to a process for drying coated workpieces, particularly workpieces of irregular shape, by infrared radiation and to an apparatus for carrying out this process. The present invention can be used for drying castings, particularly those having an irregular shape, thin-walled sheet-metal products as well as ceramic and glass products which have been coated with a powder or an electro-dipping varnish or water-soluble or solvent-containing varnishes. According to said process the workpieces are dried by infrared radiation in several zones at a specific temperature, an air flow being provided in the zones and the air being drawn off from one zone. According to the present invention the workpieces are preheated in the first preheating zone. In the second rest zone the infrared radiation is interrupted so that the temperature of the workpieces slightly decreases. In the third reheating zone the workpieces are completely dried by subjecting them once more to infrared radiation while the air is circulated and heat is additionally supplied to the workpieces by convection. The apparatus comprises a casing, wherein infrared emitters having reflectors are disposed in several zones at intervals from the casing walls, the emitters encompassing an irradiation space. The apparatus also has inlet and outlet openings and a means for conveying the workpieces through the casing and a suction device. According to the present invention a rest zone without any infrared emitters is disposed between a preheating zone and a reheating zone. The suction device in the rest zone is so disposed that the air is circulated within the casing.

Abstract: A circuit arrangement for telecommunication installations, in particular, telephone exchange installations is disclosed in which type information is sent ahead of each communication to be transmitted. In bidirectional communication transmission with different possible communication types, type information announcing the respective communication type is sent ahead. In the receiving equipment the beginning of the arrival of type information is recognized and immediately, that is, almost simultaneously, an assortment of type-specific message corresponding to each of the possible communication types is transmitted in the opposite direction, of which each indicates the readiness or non-readiness for receiving a communication of the respective type. From this and from the transmitted type information it is recognized following the transmission of type information and messages on both sides independently of each other but concordantly whether a communication transmission will subsequently occur, cannot occur or will be postponed to a later time.

Abstract: This invention relates to a device for transportation and weighing of goods e.g. for checkout desks in shops and stores. Scale tables as used until now occupies space and can be hampering for both operator and customers. Besides the movements which are required for the weighing may cause health problems for the operator. To eliminate these problems the device for conveying and weighing of goods according to the invention has a scale integrated with the conveyors (3,10,11), such that the weighing takes place while the goods is on the conveyor (3). When a weighing shall take place the conveyor (3) is stopped and the weight of the goods is registered whereupon the conveyor (3) is started. The scale device comprises a scale table (1) which signalling device (2) is mounted onto a stand (4) by a holder (8). The conveyor of the scale passes rolls (5,6) which are also mounted onto the scale table (1). The signal from the signalling device (2) which corresponds to the weight of the goods can be treated in different ways and for example in the cash register be combined with information from an index with prices for different kinds of goods. The driving arrangement of the conveyor is controlled by signals from a scanner (9). <IMAGE>
