Patent DE-3161158-D1 (DE)
Title: Arrangement for die casting metals and alloys
Inventor: VUTOV STANTSCHO CHRISTOV DIPL-
IPC: B22D17/32
Filed: 1981-04-01
Granted: 1983-11-17
Abstract: The invention relates to an apparatus for pressure die casting of metals and alloys involving the action of increased gas pressure on the solidifying melt. In this apparatus, the gas is pressurized automatically during the stroke of the press and pressurized gas at elevated pressure is applied to molten metal in the die cavity immediately after the closing of the die. For this purpose, the apparatus comprises a hydraulic press including a cylinder and a piston slidably mounted therein, which piston divides the cylinder into a first and second chamber. The first chamber is in communication with a source of pressurized liquid and the second chamber is in communication with a gas retaining cavity disposed in the piston rod of the piston. A press plate and die having at least one die cavity is rigidly mounted on the piston rod. The cavity of the die is connected by means of corresponding valves to a supply reservoir with gas under low pressure. The gas retaining cavity within the piston rod is filled up to a fixed level with working liquid from the hydraulic system of the press. The bottom part of this cavity is connected to the second chamber of the pressing cylinder below the piston. This second chamber is connected to the hydraulic system of the press by means of a valve. The upper part of the gas retaining cavity is connected simultaneously by means of a check valve to a supply reservoir for gas and by means of a shut-off valve to the die cavity. The die cavity is connected by means of another shut-off valve to the atmosphere.

Patent DE-3363822-D1 (DE)
Title: Soap dispenser with a device indicating the level of a liquid soap
Inventor: ARABIAN SANDRO
IPC: A47K5/12
Filed: 1983-12-05
Granted: 1986-07-03
Abstract: The soap solution dispenser contains a reservoir into which opens an outlet or outflow opening of a container. In the reservoir there is present a float body or float which is pivotably mounted and provided with at least one indicator flag. Conjointly with the drop of the liquid level in the soap solution reservoir the float body also descends, which causes a displacement of the indicator flag. During the lowering of the surface of the soap solution the indicator flag moves along a viewing window formed in a cover or covering hood. There is thus signalled or indicated that the content of the soap solution in the reservoir is quite small or nearly consumed, so that the container now should be exchanged. One resulting advantage of the invention is that the indicator flag moves externally of the soap solution, so that the indicator flag cannot become stuck or bind, and thus, always remains readily visible.

Abstract: A mold changer for an injection molding machine has a carriage with two mold stations mounted next to the molding machine. The carriage is movable parallel to the tie rods (or platen movement) of the molding machine to position a selected work station in register for mold changing. There are rollers on the machine platens and at each carriage work station to support the mold weight while permitting lateral movement of the mold into or out of the machine or carriage as part of mold changing.Separate drive means to power such lateral mold movement are on each of the machine and carriage. Each of the drive means selectively moves a mold the first part of the way from the device in which it is mounted (i.e. machine or carriage) into the other device (carriage or machine) and at some point the drive means in the receiving device assumes driving and completion of the mold change. The mold is constructed and arranged to engage and disengage the drive means.

Date Apr. 24, 1986.A spray cooling system for cooling a furnace for the melting or treatment of molten metal, and particularly the roof and/or sidewall of electric-arc, plasma-arc and ladle furnaces. Other types of metal treating furnaces and accessory equipment may also be cooled with the system of the invention. In the invention, spray headers and pipes (14, 16, 18) supply coolant to spray nozzles (70) distributed within a coolant space in a roof structure (10) to spray coolant against the working plates (22) of the roof. The spray pipes and headers also comprise part of the framework for the roof, resulting in a simple, lightweight, one-piece structure. A pump (56) is connected to evacuate the coolant from the coolant space, and thermocouples (58) are embedded in the working plates to monitor their temperature and operate controls to adjust the flow rate so that only the amount of coolant necessary to maintain a desired temperature is supplied to the roof. The sprays of coolant produce many small droplets which provide a large surface area for more effective cooling, and at least a substantial portion of the droplets are vaporized during cooling whereby the latent heat of vaporization of the coolant is utilized to provide a significantly increased cooling rate. Similar arrangements may be used to cool the delta and/or sidewall of the furnace. The method of cooling a furnace by directing sprays of coolant against the working plates is also disclosed.

Abstract: The invention relates to a synchronization method for radio transmitters of a local, e.g. nationwide paging network. A paging network is connected to a public switched telephone network and comprises a paging network unit (PNU), transmitter group controllers (TGC) and transmitter site interfaces (TSI). All controllers are provided with means for receiving, processing and transmitting messages in digital form. Base stations are provided with radio transceivers (Tx, Rx) transmitting radio signals intended for paging or for synchronization of the base stations covering a common overlap area. With the method of the invention, synchronization is performed on the basis of a synchronization plan composed by paging network unit (PNU) and synchronization commands based on the plan. Synchronization proceeds sequentially in a certain order so that each base station (except for the initiator) first receives and then transmits a synchronization signal. Prior to the transmission of a synchronization signal, compensation of delays is executed based on one hand on receiving own transmission and, on the other hand, on information given by the paging network unit PNU about distances between base stations. The synchronous transmission of paging information is confirmed to be independent of a digital data transmission network by determining the exact time of radio transmission of each page according to a plan made beforehand by the paging network unit.
