Patent CA-2078550-A1 (CA)
Title: Plant growth regulation
Inventor: YOUNG DONALD C
IPC: A01N25/22
Filed: 1991-03-18
Abstract: L-(d)-lactic acid, the dextrorotatory isomer of lactic acid, is an effective plant growth regulant which exhibits classical growth regulant activity at very low concentrations and dosage rates.  It can be employed to beneficially stimulate the growth of all plant varieties and is particularly useful for stimulating the growth of commercial crops. Thus, L-lactic acid can be employed to stimulate the growth of desired plants and to stimulate the fruit production of fruit-bearing plants. Novel compositions which comprise mixtures of L-(d)-lactic acid and one or more preservatives which are sufficient to prevent the hydrolytic and/or bacterial decomposition of the active isomer are also disclosed.

Title: Everlasting hinge
Inventor: CIVITILLO ANTONIO
IPC: E05D5/06
Filed: 1992-11-06
Abstract: A B S T R A C T          The common hinge is attached only to one side of the door and to one side of the jamb. This is why it happens very frequently for heavy doors and for doors often used to come off the top hinge --the one which holds most of the weight of the door when it is operating.          This invention provides the top hinge with a very good grip of the jamb ( on two sides ) and of the door ( on three sides ). This way we prevent the door from coming off the top hinge which means:      - more strength and tamper-proof for the door - no more damage to the jamb and door - no more dragging doors The use of this invention can be extended to all the hinges that one door has.

Title: Process for the casting of metals in a continuous casting installation with continuous strand withdrawal
Inventor: HOEFFKEN ERICH
IPC: B22D11/18
Filed: 1992-11-13
Abstract: ABSTRACT         A process for the casting of metals in a continuous casting installation, wherein a strand of metal is continuously withdrawn from the mould and the casting process is controlled in dependence on stresses occurring in the continuous casting installation during the withdrawal of the strand, characterized in that during continuous strand withdrawal a measurement is made of expansion of an inside wall of the mould caused by occurrences of mechanical forces in the strand withdrawal direction, and the measured values thus obtained are so used to control the casting process that the casting speed is reduced or the casting process interrupted when given limit values are exceeded.

Abstract: Docket 7501-C     SELF-CLEANING NOZZLE FOR A GAS WELDING TORCH                       Abstract of the Disclosure A welding torch for gas metal arc welding has a torch body which conducts electricity, receives a cable for directing a welding wire, and defines a passage for directing a shielding gas.  A conductor tube has an inner end portion secured to the torch body and a free outer end portion, and a contact tip is secured to the outer end portion of the conductor tube.  The contact tip has a central bore which directs the welding wire through the tip, and a diffuser directs the shielding gas around the contact tip and conducts electrical power to the contact tip. A tubular welding nozzle body is formed of a porous polycrystalline graphite  material  and  has  a  slightly  tapered  inner  surface  which surrounds the contact tip for collimating the gas while substantially reducing the accumulation of spatter on the nozzle body.  The contact tip may also be covered with the same graphite material to impede spatter accumulation,  and the porous graphite material  is  impregnated with petrolatum and wax to extend the service life of the body.  The tubular nozzle body may be protected by a surrounding copper jacket,  and an interfitting band of ceramic material retains the body within the jacket.

Title: Computer apparatus and method for graphical flip book
Inventor: KNOWLTON KENNETH C
IPC: G06F3/048
Filed: 1991-06-20
Abstract: Computer apparatus and method replicates a book in screen views of a video display unit. A book representation is formed of a multiplicity of entities positioned in a series and successively overlapping each other. Data of only non-overlapped entities or portions thereof are viewable. Processor means changes display of the series such that desired entities are displayed non-overlapped in a respective position in the series. Each entity succeeding the desired entity in the series overlaps a respective succeeding entity, if any, and each entity preceding the desired entity in the series overlaps a respective preceding entity, if any, to display the desired entity non-overlapped in the series. Screen view position of viewable data in the series thus changes as a function of entity providing the data and corresponding serial position of the entity. A processor procedure adjusts position of user definable tabs coupled to entities to maximize viewability of tabs.  Page numbers and other markers are employed to provide indications of the positions of the entities in the series. Alternatively, entities nearest the non-overlapped entity are less overlapped by neighboring entities than entities farther away from the non-overlapped entity are overlapped by respective neighboring entities.

Abstract: A controlled-output power amplifier (50) is provided having a wide dynamic range in a plurality of output power level The controlled output amplifier (50) includes an amplifier (12) for receiving an input signal (14) and for providing an output signal  (16)  therefrom.   A power detector (24) is employed for rectifying a sample signal and providing a DC output signal  (26)  therefrom.   An active variable coupling network (52) which preferably includes a varactor (62) connected between the output of the amplifier (12) and the power detector (24).  The variable coupling network  (52)  receives the amplifier output signal  (16)  and further receives an isolation voltage (54) and adjusts the amount of isolation between the amplifier (12) and the power detector (24).  For high output signals, the isolation voltage (54) causes a high isolation thereby causing less power to be transferred to the power detector  (24).   The isolation voltage  (54), similarly, decreases the isolation for low output signals such that more power is transferred to the power detector (24).  The DC output signal (26) is then compared with a fixed voltage reference  (30).   The voltage comparison provides an error voltage (34) which is used to adjust the gain of amplifier (12) so that the output signal (16) of the amplifier (12) is set to a desired magnitude.
Patent CA-2095063-A1 (CA)
Inventor: ERIKSSON STINA
IPC: C01B11/14
Filed: 1993-04-28
Abstract: The  invention  relates  to  a  method for separating sulphate from an aqueous  electrolyte  in  an  alkali metal chlorate process,  thereby reducing  the operating cost and increasing the possibility of further closing  the electrolytical production  of alkali  metal chlorate. Calcium ions are added to a portion of the electrolyte,  for precipitating calcium  sulphate. By adjusting the pH within the range of from 4.6 up to about  7, and  combining the temperature, content of  ions and  the molar  ratio between sulphate and calcium  ions  added  in  a  suitable  manner,  the calcium sulphate  will  precipitate  predominantly  as  gypsum  and essentially without inclusions  and/or  co-precipitation of chromium-containing compounds  or chlorate. The precipitate is subsequently removed from  the  portion  of electrolyte, whereafter  the  thus  purified  portion  of electrolyte is recycled to the chlorate process. Any fluoride ions  in the electrolyte can  also be removed by the addition of calcium ions and a subsequent co-separation of the calcium fluoride precipitated with the calcium sulphate.
