Filed: 1981-06-24
Abstract: The present invention is formed by two main parts (1) and (2) which comprise two laminated rods (3) and (4) provided, spacedly and from one of its longitudinal edges, with a a number of semi-rings (5) and (6). Parts (1) and (2) are linked to each other by means of rectangular rings (8) or by means of a wire (7). Being the binder at the closed position, rods (3) and (4) are juxtaposed and the semi-rings (5) and (6) form a number of closed rings retaining perforated leaves or sheets. Being the binder at the open position, rods (3) and (4) may rotate between each other by up to 180 DEG , the terminations of semi-rings (5) and (6) being offset from each other, so as to permit removal or placement of leaves or sheets. The binder is provided with a removable rod (9) which adjusts itself to rods (3) and (4), these being juxtaposed, so as to hold the binder in the closed position.

Filed: 2000-07-24
Abstract: L'invention concerne des procédés permettant d'améliorer la croissance ou la production des plantes, consistant à exposer le sol à l'hydrogène gazeux (H2) et à cultiver des plantes dans ledit sol. Le gaz H2 utilisé peut être obtenu par électrolyse de l'eau, produit par des micro-organismes en évolution et/ou par des légumes. Selon l'invention, le sol peut d'abord être exposé à l'hydrogène puis utilisé pour y cultiver des plantes, mais on peut également appliquer l'hydrogène à un sol dans lequel des plantes sont déjà cultivées. Dans un mode de réalisation, l'invention consiste à obtenir un extrait aqueux à partir d'un sol traité à l'hydrogène, puis à appliquer cet extrait au sol, aux graines et/ou aux racines des plantes.

Title: Fiber optic sensors
Inventor: WLODARCZYK MAREK T
IPC: G01N21/27
Filed: 1990-02-02
Abstract: ABSTRACT OF THE DISCLOSURE Several  improvements  in   fiber optic   sensing  systems   are disclosed.   One  improvement  incorporates  a  dielectric  filter  applied directly to the  sensing end  of an optical  fiber detector  which has  the characteristic that  it  reflects  back  a  reference  light  beam  of  one wavelength while passing a sensing  signal of a different wavelength  which is modulated in some predetermined  fashion beyond the filter.  Both  light signals  are  reflected  back  through  the  fiber  and  are,  accordingly, attenuated in  an identical  or  nearly identical  fashion in  response to various noise sources.  The  ratio of the intensity  of the two signals  is proportional to the  sensed parameter  and renders  the system  essentially self-compensating.  The  dielectric filter  is preferably  directly  coated onto the exit end of the  fiber through vapor deposition techniques.   Time division multiplexing is used to sequentially fire plural light sources and a single photodetector is used for measuring the intensity of the reflected back signals of the various wavelengths.  Another improvement  encompasses the detection unit in which the  input and reflected signals are  separated using an  off-axis parabolic  mirror  which provides  excellent  separation efficiency.  According to  another principal feature  of this invention,  a concave surface is formed  at the fiber end  which increases the  numerical aperture of the fiber which provides greater sensitivity to the  deflection of a pressure  sensitive diaphragm  spaced from and  confronting the  fiber end.
Patent CA-2010414-A1 (CA)
Inventor: TOBUSE HIROAKI
IPC: H01L21/027
Filed: 1990-02-20
Abstract: ABSTRACT OF THE DISCLOSURE     Printing pattern information from a printing pattern CAD is converted and output as deflection scanning data for the X-axis and the Y-axis by a deflection scanning data generating means.  An electron beam deflection scanning means executes deflection scanning by an electron beam on a circuit printing base on the basis of the output deflection scanning data.  The printing pattern irradiated with the electron beam is input to a bit map memory by dots which correspond to the points which are irradiated with the electron beam.  A radiation control means can ascertain whether or not the point which is to be irradiated with the electron beam has already been subjected to beam irradiation at real time by consecutively reading out the dot informa-tion in the bit map memory at the address corresponding to the deflection scanning data.  If there is no dot, a dot is written in the bit map memory simultaneously with beam irradiation, while if there is a dot, a blanking means outputs a control signal for cutting off the electron beam. Thus, overlap in printing pattern is detected at real time, thereby ensuring the avoidance of multiple beam radiation, namely, multiple exposure.

Title: Process of controlling the slag in a top-blowing steelmaking converter
Inventor: ABERL HEINRICH
IPC: C21C5/30
Filed: 1990-05-18
Abstract: In the operation of a top-blowing steelmaking converter having at least one blowing lance, the distance of said lance from the surface of the molten metal bath is controlled in dependence on the sound levels of the blowing noise measured through the slag at selected frequencies.  In order to minimize the risk of slopping, the actual values of the sound levels measured at predetermined frequencies are combined to form a resultant value, the difference between said resultant value and a predetermined reference value, which is associated with a sound level and indicates that sloping is likely to occur, is determined, and said difference is used as an indication of the probability of an occurrence of slopping and is compared with at least one predetermined probability limit, the distance of the blowing lance and optionally also the oxygen supply rate is corrected when said difference exceeds said probability limit.

Title: Female incontinence control device with magnetically operable valve and method
Inventor: CHIN REBECCA Y
IPC: A61F2/00
Filed: 1990-11-01
Abstract: A female incontinence control device includes a conduit having inlet and outlet openings for receiving, conducting and discharging urinary fluid. The device also includes stabilizing structure, which can be adjustable, for holding the conduit in its installed position relative to the urethra and bladder such that a drainage inlet opening can receive fluid from the bladder, and the outlet discharge opening is positioned outside the urethra. The conduit includes a magnetically actuatable drainage control valve adapted to be positioned between the urethral orifice and the labia majora. Magnetic actuation of the valve from a normally closed position to an open position is thus easily accomplished by manipulating a portable magnet at a distal end of the conduit outside the urethral opening to selectively control urinary flow through the conduit. The method of controlling female incontinence includes the steps of providing and positioning a conduit to receive the urinary fluid and magnetically actuating the valve in the conduit by manipulating a magnet proximal the conduit in the vicinity of the valve to open the valve and allow accumulated urinary fluids to be drained through the outlet opening. Removal of the magnet permits the valve to automatically close.

Abstract: An interference cancellation system for cancelling at least two interfering signals received simultaneously and which is adapted to be connected to a radio receiver system having a receiver antenna, a receiver and a receiver transmission line interconnecting the receiver antenna and the receiver includes an auxiliary antenna, a first directional coupler connected to the auxiliary antenna, a second directional coupler connected to the receiver transmission line, a synchronous detector connected to the first and second directional couplers, a signal controller connected the synchronous detector and a subtractor connected to the receiver transmission line and to the signal controller.

The auxiliary antenna is spaced apart from the receiver antenna a predetermined distance so that the two interfering signals are received by the two antennas with a phase difference which is equal and opposite to that which is introduced by the auxiliary antenna. As a result, the two interfering signals are received in the interference cancellation system in the same phase relative to the receiver antenna.
