Title: A method for determining the rotational position of a crankshaft of an internal combustion engine
Inventor: YOUNG PAUL M
IPC: H03M1/30
Filed: 1992-05-18
Abstract: In one aspect of the present invention, a method determines the rotational position of a crankshaft (110) of an internal combustion engine (100). The method includes monitoring the rotation of the crankshaft (110) and responsively producing a crankshaft pulsetrain. A clock signal is produced having a predetermined frequency. The clock signal and the crankshaft pulsetrain are received.  Each pulse of the crankshaft pulsetrain is sampled, and responsively the period of each sampled pulse is determined. Signals representative of the determined pulse periods are produced. The method further includes receiving the determined pulse period signals, and responsively determining a value which is predictive of a period of the next pulse to be produced. A signal representative of the predictive value is produced, and the predictive value signal is received. An intermediate position signal based on the predictive value is produced. The intermediate position signal is representative of a predetermined angular rotation of the crankshaft (110).

IPC: G06K19/16
Filed: 1992-05-29
Abstract: An optical memory diffraction grating (80) having a plurality of spaced ridges (81) each having a plurality of optically reflective facets (82, 83 and 84). When illuminated with an incident light beam (85) the grating (80) produces a number of diffracted beams (86, 87, 88) corresponding to the number of facets. The diffracted beams can be machine read by a reading device which produces a reading light beam (131) directed at the grating. The reading device has a plurality of detectors (135) positioned to be illuminated by the diffracted light beams. Information can be stored in the optical memory by locally changing the optical properties of the grating (80). The grating (80) may be employed in security cards and documents. The grating (80) may be arranged as a bar code (11) or as a pixelgram (160). Reading, writing and erasing devices are also claimed.

Title: Bearing plate
Inventor: CALANDRA FRANK JR
IPC: F16B43/00
Filed: 1994-03-07
Abstract: An elongated channel beam for supporting the surface of an underground rook formation includes a base portion with a bearing surface for contacting the rock strata and an opposite surface having a longitudinally extending central rib and flanged edges for resisting deflection and bending of the channel beam under the load of the rock strata. A plurality of openings spaced a preselected distance apart extend through the central rib. A bearing plate is positioned in overlying abutting relation with each opening in the channel beam. The bearing plate includes embossed areas and longitudinally flanged edges that overlie in abutting relation the central rib and flanged edges of the channel beam. The bearing plate is restrained from longitudinal and lateral movement on the channel beam. Anchor bolts extend through the aligned openings in the bearing plate and channel beam into bore holes drilled in the rock formation.      Tightening the anchor bolt compresses the bearing plate against the channel beam with the compressive forces distributed over the surface of the bearing plate and transmitted throughout the channel member to support the rock formation.

The tendency of the particles to sinter and agglomerate is further reduced by the additional removal of sodium, iron, calcium, and titanium impurities from the outer peripheral surface layer of the particles. Preferably the latter named impurities, or impurities other than silicon and boron, are reduced to a concentration below about 20 atom %, more preferably to a concentration below about 15 atom %, in the outer surface layer of the particles.

Title: Apparatus for simultaneously applying brakes of a trailer when brakes of a towing vehicle are applied
Inventor: SAFFRAN GENE E
IPC: B60T7/16
Filed: 1994-06-21
Abstract: An apparatus for simultaneously applying brakes of a trailer when brakes  of  a towing vehicle  are  applied  is described.    The  apparatus  includes  a vacuum pump  which communicates with a vacuum booster in a braking system of the trailer  thereby  providing vacuum pressure  to  the  vacuum booster.  A servomotor is linked to an activating arm that moves a plunger that acts through the vacuum booster upon a master brake cylinder of the trailer.  Upon activation, the servomotor provides force to move the plunger thereby sending braking fluid from the master cylinder to brakes  in the trailer.  A pedal position sensor communicates with a brake pedal in the towing vehicle, whereby the brake pedal position of the towing vehicle is sensed.  An encoder communicates with the pedal position sensor.  The encoder receives data from the pedal position sensor regarding the brake pedal position of the towing vehicle and encodes such data. A decoder communicates with the encoder and the servomotor.  The decoder receives an encoded signal from the encoder regarding the brake pedal position of the towing vehicle and sends a decoded signal to the servomotor to move the plunger in the trailer thereby creating a master to slave connection between the brake pedal of the towing vehicle and the plunger acting upon the master braking cylinder of the trailer.

Title: Sockets serving for the connection of two plastic pipes and process for the production of such a socket
Inventor: CARLSTROEM BOERGE
IPC: F16L47/06
Filed: 1995-07-07
Abstract: The socket has an essentially cylindrical outer layer of glass fiber-reinforced plastic and a sealing sleeve arranged in a recess in the outer layer.  This sealing sleeve has, between the two socket ends, a rib serving as a stop for the ends of the two pipes to be connected to one another.  Here, the outer layer forms a first and a second hollow cylindrical, dimensionally stable edge section, the first of which is substantially longer than the second.  That end of such a socket which is formed by the longer edge section can be pushed relatively easily onto a first pipe and can also be nondetachably bonded thereto by means of an adhesive.  The second pipe having the same diameter can then be inserted into the socket end formed by the shorter edge section.  Here, the relatively short edge section makes it possible to insert the second pipe into the socket with a tight seal even when the axes of socket and pipe do not coincide but make a small angle with one another.
Patent CA-2154310-A1 (CA)
Inventor: BOYER PIERRE
IPC: H04L12/56
Filed: 1995-07-20
Abstract: Bit rate reservation is effected by means of a reservation cell containing a requested bit rate transmitted from a calling terminal  to  a  called  terminal  via  switching  nodes  of  an asynchronous  network.    At  each  node,  a  bit  rate  increase request is at least partially satisfied even if the difference between the requested bit rate and the current bit rate is greater than the bit rate available at the node.   The node replaces the requested bit rate in the reservation cell by a new bit rate lower than the latter so that the called terminal receives the lower new adopted bit rate by the nodes.   An acknowledgement cell retransmitted with this lower new bit rate by the called terminal renders uniform the adopted bit rate at all the nodes.   If no acknowledgement cell has been received after a predetermined time-delay the nodes revert to their initial state, with the current bit rate preceding the bit rate reservation.
