Title: Cooling of scissors for cutting of glass gobs.
Inventor: MENZEL PAUL
IPC: C04B7/12
Filed: 1988-09-23
Abstract: The invention relates to a method of cooling a cutting element of shears used to cut a string of liquid glass into glass gobs for the manufacture of glass objects, for instance glass bottles, in which method a string of liquid glass mass is taken from a glass melting furnace and cut into suitable gob-forming lengths with the aid of the shears, and in which the cutting element of the shears is liquid cooled. The cutting element of the shears is cooled with a cryogenic liquid which is applied to those surfaces of the cutting element which come into contact with the liquid glass mass. The invention also relates to an arrangement for cutting a glass gob from a string (3) of liquid glass in the manufacture of glass object, for instance glass bottles, the arrangement comprising two mutually co-acting cutting elements (2; 41, 42), coolant conducting conduits (23, 13, 11, 11') provided with a nozzle (51; 45, 46) effective in bringing a coolant into contact with the cutting elements (2, 41, 42). The inventive arrangement is characterized by a pressure vessel (14) which includes a phase separator (16) in the conduit line (23, 13, 11, 11') at a location between a source (21) for cryogenic liquid and the nozzle (51; 45, 46).

Abstract: The silo according to the invention consists of a central cone (3) which is surrounded by an annular silo bottom (5) fitted with fluidising devices (6). Emptying channels (8) extend radially, i.e. in a star shape, to outlet housings (10) in the central cone. From the outlet housings, conveying grooves (11) lead to a collector (21). Metering slides (12) are arranged in the conveying grooves. The emptying channels (8) are constructed in two storeys by means of an upper and a lower level (7, 9). Adjacent to the silo wall (2) or a slope (4) provided there, the upper level has a product inlet opening (16) for the lower level. The air conveying grooves (7 and 9) of the two levels located one above the other are optionally aerated, preferably alternately. By this means, emptying or mixing vortices are produced in each case on an outer and an inner base line. These vortices oscillate back and forth between the base lines, thus ensuring a good mixing. The constructional expenditure in respect of the parts arranged in the central cone is not greater than in conventional silos. It can even be reduced. Furthermore, it is possible with the aid of so-called frictional engagement technology to control the flows of the product from the two levels and to manage with only one metering slide per conveying line or groove.

Abstract: Separate, but related, firmware programs for multiple microprocessor-controlled irrigation controllers that are interrelated in their control of irrigation within an irrigation system are generated off-line at a personal computer. The programs are downloaded into a transportable memory device that holds sixty-four separate programs. The memory device is transported to each irrigation controller and plugged to a digital communication channel. The device automatically identifies itself to the controller, and vice versa. The appropriate program is automatically uploaded from the device to the controller. The controller's old program and its historical irrigation record data is loaded into the device and delivered to the personal computer for validation and analysis. A wireless remote test command assembly, an extension maintenance panel, or a radio-link central module may be alternatively connected to the controller's digital communication channel. The controller is powered by the memory device during the uploading.
