Patent CA-2035008-C (CA)
Title: Improved shotcrete compositions
Inventor: DRS JOSEF F
IPC: C04B24/04
Filed: 1991-01-25
Granted: 2002-11-05
Abstract: The storage and processing times of sprayed concrete can be signifi-cantly extended by the addition of a retarder, a chemical compound which is capable of chelating with calcium ions. Preferred retarders are phos-phonic acid derivatives which have at least one amino and/or hydroxyl group. The retarder can be used for both wet- and dry-sprayed concrete, the usual accelerators can be used for activation, and the strength is not adversely affected.

Title: Group control for lifts with double cages with immediate allocation of target calls
Inventor: SCHRODER JORIS THEODOR
IPC: B66B1/14
Filed: 1991-05-21
Granted: 2003-07-22
Abstract: In this group control, upper as well as also lower cages of the double cages can be used at a main stopping place for journeys to even-numbered and odd-numbered storeys. For this purpose, a respective call store (20, 21), in which the calls entered at the main stopping place and identifying the target storeys are stored, is associated with the lower and the upper cage. A switching circuit (32) at its input side stands in connection with the call stores (20, 21) in such a manner that the double cage concerned is scheduled in dependence on a allocated call as stopping at storey pairs numbered even-odd or odd-even. At the output side, the switching circuit (32) is connected with a switching equipment (31), which has the effect that either the double cages stopping at storey pairs numbered even-odd or the double cages stopping at storey pairs numbered odd-even are excluded from the allocation process in the case of a further call still to be allocated in order to maximise the possibilities for co-incident stops without losing flexibility.

Patent CA-2076894-C (CA)
Title: Three axis thruster modulation
Inventor: YOCUM JOHN F
IPC: B64G1/26
Filed: 1992-08-26
Granted: 1998-11-03
Abstract: The three axes thruster modulation (8) of the present invention accepts three axes of input torque commands or angular acceleration commands and generates thruster selection and thruster timing (40) information which is used to fire thrusters (48) for the purpose of spacecraft attitude control and velocity change maneuvers. The modulation logic (8) works in all three axes simultaneously and is suitable for use with an arbitrary thruster configuration,including a configuration in which individual thrusters or thruster groups do not produce torques about mutually orthogonal axes. After thruster selection and on-times have been determined, the modulation logic (8) uses this information to compute a best estimate of the actual rate change (42) which is then compared to the commanded rate change (44) to develop a residual unfired rate change. The residual unfired rate change is retained and fed forward for addition to the subsequent acceleration command in computing the commanded rate change for the subsequent sample period (10, 20, 30). As a result, all commanded rate changes will ultimately be fired even if the commanded rate change is below a minimum rate change achievable.

Granted: 1999-01-26
Abstract: An equalizer/decoder for a communication channel presenting impairments to error-free reception of transmitted symbols includes a modified Viterbi decoder operating on samples of received signals in a plurality of equivalent subchannels.

Patent CA-2142388-C (CA)
Inventor: SEGAL MORDECHAI
IPC: H03H21/00
Filed: 1995-02-13
Granted: 2000-05-02
Abstract: Analog signals representing individual digital values (+/-1, +/-3) pass through a telephone line to a receiver.      These signals may be first provided in a pseudo random sequence. A linear echo canceller and a first adder eliminate, to an extent, echo signals resulting from second analog signals transmitted on the same telephone line by the receiver. A  non-linear echo canceller and a second adder further reduce the echo signals and specifically reduce non-linear components in the echo signals. Adjustable signal delays achieve optimal performance of the linear and non-linear echo cancellers. An equalizer containing four (4) different modules then compensates for signal distortions introduced by the telephone line and minimizes the effect of noise in the telephone line.   The equalizer modules are a digital gain control element, a feed forward digital filter and two (2) feedback digital filters. A detector module produces in one of several different ways at the receiver an estimate of the digital data (+/-1, +/-3) transmitted at the other end of the telephone line. The detector either extracts the digital information based on peaks in the received (non-equalized) signal or by adding the equalized signals with preset threshold values. A scrambler-descrambler module locally generates a replica of the digital symbols transmitted in analog form at the other end of the telephone line, based on a limited number (e.g. 23) of correctly detected digital values. The scrambler-descrambler module may also operate as a descrambler to recover data scrambled by the transmitter at the other end.
