Title: Internal garment hanger
Inventor: BLANCHARD RUSSELL O
IPC: A47F7/19
Filed: 1990-06-21
Abstract: INTERNAL GARMENT HANGER                 ABSTRACT OF THE DISCLOSURE         An internal garment hanger adapted to support a garment from an inner surface of a waistband includes an elongated body defining open ends and longitudinally extending slots.  A pair of  elongated slides are provided which telescope into the ends of the body.  Each slide includes an outer end configured to engage the garment.  An elastomeric member or spring has an end fixed to the slide and an end fixed to hanger body.  The member or spring resiliently biases the slide out of the open end of the body and into gripping engagement with the garment.  Each slide defines a stop which limits outward movement of the slide with respect to the body.  In the preferred form, the elastomeric member is molded and bonded to the slide in the manufacturing process.

Title: Fuel injection timing control for a crankcase scavenged two-stroke engine
Inventor: TROMBLEY DOUGLAS E
IPC: F02B75/02
Filed: 1990-10-23
Abstract: FUEL INJECTION TIMING CONTROL FOR A CRANKCASE    SCAVENGED TWO-STROKE ENGINE          Abstract of the Disclosure A method and apparatus for improving the output torque response of a crankcase scavenged, two-stroke engine to a change in throttle position by adjusting the conventional timing of cylinder fuel injection as a function of the position of the throttle and the time rate of change in the throttle position. Preferably, throttle position is measured with a potentiometer connected to the engine air intake throttle, and then filtered with a filter having a first order lag characteristic.  Injection timing is advanced based upon a first predetermined schedule as a function of the measured throttle position.  The difference between the measured and filtered throttle positions represents an indication of the time rate of change of throttle position and is employed to advance or retard timing in accordance with the second predetermined schedule, depending upon whether the difference is positive or negative, respectively.  As a result, a substantially linear relationship is established between the output torque of the engine and the position of the throttle over its entire range of movement, and the amount of time required for the engine to respond to abrupt changes in throttle is reduced.

Title: Wavelength detecting apparatus
Inventor: WAKABAYASHI OSAMU
IPC: G01J3/26
Filed: 1990-05-18
Abstract: ABSTRACT    The present invention provides a wavelength detecting apparatus for detecting the wavelength of a light (11) to be detected  with  reference  to  a  reference  light  (31)  by allowing the reference light (31) generated and transmitted from a light source (30) and the light (11) to be detected to be irradiated toward an etalon (62) and then detecting the light which has permeated through the etalon (62) by optical detecting means (64).  The reference light and the light to be detected are incident on the focusing surface (50) which is located in front of a collimeter lens (61).       The incident light is transformed into a parallel light in the collimeter lens  (61)  and the parallel light is then irradiated toward the etalon (62).  The reference light and the  light  to  be  detected both  of which have permeated through the etalon (62) reach the detecting surface of the optical detecting means to build their images thereon with the  aid  of  image  building  lens  means  (63),  whereby interference fringes corresponding to the reference light and the light to be detected are formed on the detecting surface  of  the  optical  detecting  means.   The  optical detecting means detects a relative wavelength of the light to be detected relative to the reference light,  i.e.,  an absolute wavelength of the light to be detected by detecting the interference fringes.

Patent CA-2041651-A1 (CA)
Inventor: TELLERMAN JACOB
IPC: G01B7/02
Filed: 1990-08-08
Abstract: A displacement transducer (10) utilizes a torsional strain waveguide (20) having a magnetic member (17) that is adjustably positioned along the length of the waveguide, when an electrical current pulse is passed along the waveguide (20) and reaches the magnet (17) a torsional strain wave is created in the waveguide (20). The torsional strain wave will be reflected back toward a mounting end of the waveguide (20) where a converter or sensor (32) is positioned to sense the strain wave signal and convert it to an electrical output signal. The strain wave signals have signal lobes of a time period. A waveguide mounting block (25) supports the waveguide (20) at the mounting end and provides a reflection point for the torsional strain waves. The waveguide mounting block (25) is on an opposite side of the signal sensor (32) from the magnet (17). The mounting block (25) is precisely positioned a distance from the signal sensor (32) that is equal to distance traveled by the torsional strain wave in the waveguide during one-half of the signal lobe time period so that the reflected wave becomes an additive signal to the incoming torsional strain wave signals to provide a greater amplitude to the signal being received.

Abstract: ABSTRACT OF THE DISCLOSURE:            A dental composition, such as a paste or gel dentifrice containing triclosan, as an antibacterial agent which acts to decrease plaque on the teeth, is packaged in a hand holdable and squeezable dispensing container which is made of or includes a part or parts of a solid polymeric material, such as a poly-fluoroethylene or polyvinyl chloride, which is compatible with triclosan, so that excessive loss of its anti-plaque activity on storage is avoided, which losses have been noted when various other plastics have been employed as dispensing container component materials.  Alternatively, other more reactive plastics may be employed for such dispensing container parts when a stabilizer, such as terpene, e.g., limonene, is present in the dentifrice.  The dentifrice preferably also contains an anti-tartar proportion of polyphosphate, a tooth hardening propor-tion of a source of fluoride ions, a stabilizing proportion (in conjunction with the fluoride source) for the polyphosphate, of a polyvinyl methyl ether/maleic anhydride copolymer, and normal dentifrice components and adjuvants.

Title: Process for the continuous production of sodium azide
Inventor: BIERMANNS FRANZ-JOSEF
IPC: C01B21/08
Filed: 1991-07-05
Abstract: ABSTRACT OF THE DISCLOSURE:           The present invention deals with the continuous production of sodium azide from sodium amide and nitrous oxide.  This reaction takes place on a support material for sodium amide consisting of a mixture of sodium azide and sodium hydroxide.  This mixture is passed through a reactor maintained at temperatures of between 200° and 270°C; a portion of the reaction product and the support material are transferred out of the system at an end of the reactor, and a primary quantity of the reaction product and support material are returned to the reactor inlet where  the material is combined with fresh, heated sodium amide in an amount corresponding  to the quantity of sodium azide transferred-out with the reaction product and support material.  with the aid of this continuous process,  higher spacetime yields of sodium azide can be obtained than in case of the conventional methods without increasing the danger of no longer controllable explosions.
