Abstract: A quick-release clipless pedal includes a cleat to be secured to a shoe sole and a pedal body to be mounted on a pedal shaft and releasably  retaining  the cleat. The cleat has first and second engaging parts respectively formed on front and rear ends thereof. The pedal body includes a frame portion and a tubular portion which partitions the frame portion in a transverse direction. The tubular portion receives one end of the pedal shaft. The frame portion has front and rear ends respectively formed with an opening. The pedal body further includes a pair of cleat engaging members respectively provided on upper and lower sides of the tubular portion and respectively having a claw portion to receive releasably the first engaging part of the cleat, and a pair of retaining units revertably engaging the second engaging part of the cleat. The cleat is rotatable relative to the pedal body so as to disengage the first engaging part from the claw portion. Rotation of the cleat causes the cleat to push hook units of the retaining units rearward, thereby causing the hook units to pivot and allow a lateral disengagement of the cleat from the pedal body.

Title: Closure for container openings
Inventor: STOLZ BERND
IPC: B65D47/06
Filed: 1992-07-06
Abstract: Abstract The invention relates to a closure for container openings, having a closure section consisting of a base part and a pouring spout, which is connected in one piece with the base part by means of a flexible bellows and which can be brought by means of the bellows from an initial position, where the pouring spout is retracted, into a pouring position, where the pouring spout is extended, where a bow plate with a screw stud and bows formed on it can be screwed on the pouring spout and where the bows are maintained in the plane of the bow plate by means of predetermined breaking points.  Manipulation of the closure when detaching the bow plate from the pouring spout is simplified in that the bellows has an extension section so that when pressure is applied to the bow plate the pouring spout can be brought past the initial position into a lifted position, that in the course of this the bows can be separated from the bow plate by striking against the base part of the closure section in the area of the predetermined breaking points and can be turned out of the plane of the bow plate, and that when the pressure is released, the extended bellows returns the pouring spout with the bow plate into the initial position while the bows maintain their extended position.

Title: Multiplex transmission apparatus
Inventor: HASHIMOTO KYOSUKE
IPC: H04L1/22
Filed: 1992-08-26
Abstract: A multiplex transmission apparatus in accordance with the present invention is interconnected with other multiplex transmission apparatuses via common transmission lines, and it is used for a multiplex transmission system which performs data transmission.  The multiplex transmission apparatus comprises voltage converting circuits which detect voltages of the transmission lines, the first comparator which compares the detected voltages, the second comparator which compares one voltage of the detected voltages with a reference voltage, and the third comparator which compares the other detected voltage with a reference voltage.  The comparators supply the comparison results to differential circuits, respectively, set the output of the differential circuit linked to a comparator, which is connected to a faulty line, for "L", and determine the logical sum of the outputs of the differential circuits by a logical synthesizing circuit.  By applying the determined logical sum to a multiplex transmission control circuit, the apparatus makes it possible to reduce wasteful message transmission and successfully cope with faults in the transmission lines without causing delay in transmission of messages which require quick responses and without increasing the traffic volume of the transmission lines.  The multiplex transmission control circuit detects signals on the transmission lines according to the comparison results of the comparators.

IPC: F02B75/24
Filed: 1992-11-27
Abstract: ABRÉGÉ Le moteur thermique conventionnel utilise un vilebrequin pour transformer le mouvement linéaire des pistons en mouvement de rotation. La présente invention est un principe qui remplace le vilebrequin par un double jeu de pignon-crémaillèrespour effectuer la conversion du mouvement longitudinal et alternatif des pistons, en un mouvement circulaire de l'arbre de transmission. Chaque jeu de crémaillères est relié à deux pistons diamétralement opposes et solidaires l'un de l'autre. Le mou-vement linéaire et alternatif des pistons entraîne les crémaillères et ces dernières entraînent le pignon. Le pignon entraîne l'arbre de transmission toujours dans la même direction. Les deux jeux sont disposés de façon parallèle et se déplacent alter-nativement. Les deux pignons sont montes solidaires sur l'arbre et décalés d'environ 90 degrés l'un de l'autre, ce qui permet au jeu de crémaillères-pistons en mouvement à mi-course d'absorber l'inertie de l'autre jeu de crémaillère pistons au moment d'arrêt causé par b changement de direction desdites crémaillères-pistons. Des butées anti-recul situées en fin de course des crémaillères empêchent leur désynchronisationlorsque le moteur est arrêté.

Patent CA-2082939-A1 (CA)
Inventor: WHITEHEAD MARK
IPC: G02F3/02
Filed: 1991-05-24
Abstract: An asymetric Fabry-Perot (FP) modulator includes a quan-tum well structure having wider (approximately 150.ANG.) than usual (about 100.ANG.) wells. The FP cavity has a resonance at a wave-length of an excitonic absorption peak of the QW structure. Al-though the maximum change in absorption under applied bias is less with 150° wells than with 100° wells, the characteristics of the electroabsorption are also altered, with the result that the lar-gest change occurs at the wavelength of the band-edge el-hhl ex-citon at zero bias. Absorption can be reduced by biasing the QW and hence the AFPM can have a normally-off (zero bias, zero ref-lectivity) characteristic. Such an arrangement makes possible higher contrast modulation and/or lower operating voltages. The FP modulator may be used in SEEDs.

Inventor: OMATA MAKOTO
IPC: G06F15/78
Filed: 1993-01-20
Abstract: In order to effectively accelerate issue of a RAM read instruction which is to access the same memory block as a preceding RAM write instruction, when the RAM write instruction is issued, a counter initiates counting-up of a value indicative a predetermined time duration.  When the counter counts up the value, the RAM read instruction is allowed to be issued at appropriate timing.  A time duration for which the RAM read instruction is prohibited to be issued, is much shorter than a time duration which expires when the RAM write instruction is completely finished.  Thus, the RAM read instruction issue is not required to wait for the completion of execution of the RAM write instruction as in a known technique.

Title: Height adjustment mechanism for a chair seat back
Inventor: STUMPF WILLIAM S
IPC: A47C7/40
Filed: 1993-02-17
Abstract: An improved seat back height adjustment mechanism for a chair is disclosed.  The improved height adjustment mechanism includes a U-shaped mounting bracket having a back wall and two side walls.  A longitudinal cam having a handle is rotatably mounted in the bracket between the side walls and spaced from the back wall.  A seat back support arm is insertable through the bracket between the cam and the  bracket  back  wall.    The  cam  is  provided  with  a plurality of planar faces extending in the longitudinal direction   disposed   around   about   a   third   of   the circumference of the cam.  The radial length of the line extending perpendicularly from each planar face  to the longitudinal axis of the cam increases steadily from one planar  face  to  the  next  in  one  direction  around  the circumference of the cam.  This steady increase in distance of the planar faces from the axis of the cam provides a cam action on the seat back support arm when the cam is rotated in one direction with the support arm located between the cam  and  back  wall.    When  the  support  arm  has  been sufficiently compressed between the cam and back wall, one of the planar faces will be bearing against the surface of the support arm thereby forming a positive lock between the cam and support arm which prevents loosening of the cam due to rotation of the latter to the unlocked position.

Inventor: BERNDT KLAUS W
IPC: C12Q1/04
Filed: 1993-03-30
Abstract: Methods and apparatus for detecting bacteria in samples using time-resolved light scattering and absorption measurement are disclosed. The present invention provides a system wherein a plurality of samples may be tested by providing a modulated excitation signal which is introduced into each sample and collected at a point disposed across each sample. The amplitude and phase of the collected signal are then processed to determine the time characteristics, modulation and phase of the signal after it has passed through the sample. By comparing this time characteristics, modulation and phase with the time characteristics, modulation and phase collected at a previous point in time or alternatively from a sample known to be free of bacteria, the presence of bacteria may be determined, since it has now been. found that the presence of bacteria causes a significant change in the time characteristics, modulation and phase. Preferably, diode lasers are used to introduce modulated electromagnetic radiation to the samples and a multichannel plate photomultiplier tube is used to provide a signal from which the phase and amplitude can be determined. Alternatively, in other embodiments of the present invention the modulated electromagnetic radiation may be introduced using an optical switch and the multichannel plate photomultiplier tube may be replaced by avalanche photodiodes disposed against each sample that also create a signal containing time-averaged intensity, amplitude, and phase information.      An improved optical switch is also disclosed.
