Title: Coke oven repair
Inventor: KOLVEK ROBERT E
IPC: C10B29/02
Filed: 1992-07-28
Abstract: A large size cast monolithic refractory module having high dimensional stability, good compressive loading, and good thermal shock resistance in the range of -20° to 1565° Celsius, which module may be used in the repair of the coke oven, and also a process for making such a large size cast module. The large size cast module should be of a size sufficiently large that it can replace all those silica bricks used in a course of bricks to enclose a single flue in a heating wall of a coke oven. A minimum size has a width of at least 35 centimetres, a height of at least 13.5 centimetres, and a length of at least 35 centimetres. The process for making such a module includes the steps of selecting a material which when cast will have the desired characteristics, mixing the dry refractory material with a relatively small amount of water, pouring it into a mold on a shaker table and vibrating the mold when filled, and then by firing the cast material after initial set at progressively higher temperatures up to 425° Celsius over a period of almost 60 hours.

Title: Method of forming strip products from thermoplastic materials
Inventor: CEHELNIK EDWARD C
IPC: B29C48/07
Filed: 1992-08-17
Abstract: A method of forming an elongated trim strip product comprises extruding a first strip of thermoplastic material from a die having an outlet with an area at least substantially as great as the desired cross-sectional area of the strip product in planes perpendicular to the direction of extrusion. Immediately subsequent to the step of extruding and while the extruded strip is still in a plastic state, it is passed longitudinally between cooperating forming rolls to shape the cross section of the extruded strip to the desired shape and cross section of the strip product. While the extruded strip is passing between the cooperating forming rolls, a backing strip of foil or thin metal is directed between the rolls in alignment with the extruded strip to bond the backing strip to the extruded strip.

Patent CA-2081408-A1 (CA)
Title: Composition for the cleaning of teeth and the prophylaxis of caries
Inventor: KHARTCHENKO SERGUEI V
IPC: A61K8/67
Filed: 1992-10-26
Abstract: The composition presents itself in the form of rapidly dissolving water soluble tablets, which contain multivitamins, sodium percarbonate, sodium bicarbonate, citric acid, various food flavors and food dyes. These components are mixed in such percentage and weight proportions, that when placed in contact with human saliva, a pH of 5.4 - 5.6 is created within the oral cavity. A concurrent excretion of carbon dioxide [CO2] and oxygen [0] occurs. Both of these reactions enhance the desired effect, of cleaning both soft and hard tartar from the teeth, while at the same time diminishing not only the amount of pathogenic microflora, but also the inflammatory processes in the gum and mucus membrane. The end result is a significant prophylaxis of caries, achieved without any harm being done to the enamel of the teeth. The novel effect of the invention becomes apparent in that the offered composition can be utilized in either of two forms. Firstly, the tablets may be ingested and dissolved directly within the oral cavity; or, and secondly, the same tablet may be dissolved in 150 - 200 ml. of drinking water and then ingested. A more pronounced prophylaxis occurs with the joint use of the tablet and mouth wash, one after the other. The use of the offered substance for the cleaning of teeth and the prophylaxis of caries is complemented by its use as a breath freshener and deodorizer.

Title: Methods of winding armatures with modified side pattern
Inventor: LOMBARDI MASSIMO
IPC: H02K15/09
Filed: 1993-03-04
Abstract: A method of winding coils on an armature in which the start and finish leads for the first coils to be wound are wrapped around the armature shaft between the armature core and commutator so that these leads are supported by the shaft and are largely out of the way when the later coils are wound. The start and finish leads for the later coils are not wrapped around the armature shaft, but rather run more directly to the commutator as in conventional side pattern winding.

Inventor: FAKHRI NOUREDINE
IPC: C10M175/06
Filed: 1993-07-12
Abstract: L'invention concerne un procédé de regénération des huiles usagées, comprenant une première étape de dégazage éliminant principalement les solvants volatils, l'essence et l'eau, ceux-ci pouvant ensuite être condensés et récupérés pour recyclage. On procède par la suite à la démétallisation de l'huile parmivrofiltration sur une ou plusieurs membranes minérales ayant une porosité comprise entre environ 1000 A et 5000 A. Les porosités employées lors de la microfiltration étant supérieures à celles employées lors de l'ultrafiltration (50 A à 250 A), une viscosité plus élevée peut être tolérée lors de la filtration, demandant ainsi une moins grande quantité de chauffage pour l'opération (100 C à 190 C). L'étape de dégazage peut s'effectuer préalablement à la microfiltration de l'huile ou encore simultanément avec celle-ci. L'huile ainsi traitée conserve ses propriétés initiales (100 à 130 cst) donnant lieu à une très minime quantité de friction légère.

Title: Low pressure mercury discharge lamp with thermostatic control of mercury vapor pressure
Inventor: BOUCHARD ANDRE C
IPC: H01J61/52
Filed: 1992-11-30
Abstract: The mercury vapor pressure in a low pressure mercury discharge lamp is thermostatically controlled. A low pressure mercury discharge lamp includes electrodes and a source of mercury vapor sealed in a lamp envelope (70). A heater (78) and a thermal switching device (80) are in thermal contact with the source of mercury vapor. The heater (78) is energized when the source of mercury vapor is below a predetermined temperature during operation of the lamp.  The heater (78) is preferably a resistance heater electrically connected in series with one of the lamp electrodes (72). The thermal switching device (80) can be a bimetal thermostatic switch.  The source of mercury vapor is typically an amalgam (74) selected to have an optimum mercury vapor pressure at the maximum operating temperature of the lamp. The heater (78) and the thermal switching device (80) can be located external to the lamp envelope (70) or can be located within the lamp envelope (70). The lamp provides a relatively constant light output over a broad range of operating temperatures and different lamp orientations.

Abstract: ABSTRACT                     A FILM PROCESSOR                A photographic film processor comprises six juxtaposed processing tanks (10 to 15), a rack mechanism (16) in each tank (10 to 15) operable to circulate the film within processing solution in the respective tank (10 to 15) for a certain time. A switch mechanism (17) operable to direct the film from being circulated at the end of that certain time and to direct it to a transfer mechanism (18) by which it is passed to the rack mechanism (16) of the next tank (10 to 15) for circulation in that tank. The penultimate tank (15) is a washing tank and there is a transfer mechanism (40) for transferring the film from that washing tank (15) to a dryer (43) which is the last processing station. The film is driven for circulation within and for transfer from one to the next of the six tanks by a first motor (32) which drives a common shaft (20). A clutch (35) couples or decouples the common shaft (20) to a shorter coaxial shaft (36) by which the film is circulated within the washing tank (15). Another clutch (41) couples the shorter shaft (36) to another slower motor (42) when it is decoupled form the common shaft (20) by the clutch (35) so that (15) independently of circulation of film in the other five tanks (10 to 14) and is transported out of the washing tank (15) and transferred to the dryer (43) at a speed which is slower than that of which it is circulated on and transferred between the first five tanks (i.e. 10 to 14).

Title: Transmission line fault control method
Inventor: AKIMOTO MITSURU
IPC: H04L69/40
Filed: 1992-11-27
Abstract: ABSTRACT A fault control method is provided wherein multiplex nodes (10, 11, 12) are connected to buses (A, B, C), and a fault detecting node 12 among the multiplex nodes detects abnormality of the individual multiplex nodes and the individual buses, and sets the potential of a control line C which is one of the buses, to change the states of the buses for fault detection.  Upon detecting a communication error, the fault detecting node detects the present state of bus connection (transmission mode), and changes the state of the control line C based on the type of the detected communication error and the detected transmission mode by operating a control circuit 23, to thereby cause each node to select the buses.
