Patent CA-2050000-A1 (CA)
Title: Mortar gun
Inventor: JOBIN ANDRE R
IPC: E04F21/06
Filed: 1991-08-27
Abstract: ABSTRACT OF THE DISCLOSURE            The  present  invention relates to a mortar  gun  which comprises  a  substantially vertical hopper  adapted  to  contain mortar and having a front wall,  a rear wall  and a substantially horizontal bottom wall.   A cylinder projects forwardly from  the front  wall of the hopper adjacent the bottom of the front  wall.          A  conically tapering nozzle extends integrally and forwardly  on the cylinder.   A worm feed screw rotatably lies along the bottom wall of the hopper from the back wall of the hopper and  projects within  the cylinder until it reaches the  tapered  nozzle.   The screw  has a central axis and a thread integrally mounted on  the central shaft.  An helicoidally twisted and relatively flat plate of stiff material extends integrally from the thread of the screw into the nozzle.   The helicoidally twisted flat plate  rotatably lies adjacent the corresponding inner wall of the conical nozzle.          The  helicoidal flat plate thus defines an  unobstructed  conical axial passageway leading to a discharge aperture of the front end of the conical tapered nozzle.   Upon rotation of the screw,  the mortar  in the hopper is pushed through the cylinder towards  the discharge nozzle by the feed screw.   The mortar in the nozzle is pushed through the passageway by the mortar leaving the  cylinder and  by the helicoidal flat plate which frictionally transmits  a forward thrust to the mortar.   The plate also scrapres the inner wall of the mortar to prevent the mortar from sticking to it.

Patent CA-2061564-A1 (CA)
Inventor: OHKI JUNICHI
IPC: H04N7/50
Filed: 1992-02-20
Abstract: Time-varying picture signals of a plurality of channels are predictively coded by utilizing the interframe correlation, and are multiplexed at the transmitting side. After transmission the signals are separated at the receiving side for each channel, and a channel is selected and switched for decoding. When the receivingchannel is switched over to another channel, a decoding error can occur and a reproduced screen can collapse since the predicting signals do not coincide witheach other at the transmitting and receiving sides. Therefore, when the plurality of channels is selectively switched for decoding by using a single decoder, the refresh is repeated at predetermined time intervals in a short period of time by utilizing the intraframe correlation when the coding is carried out at the transmitting side. Thus, even if the channel is switched, an excellent reproduced screen may be immediately obtained. However, during the refresh, the compression ratio is reduced comparedwith that of the bit rate when a normal interframe correlation is carried out. Therefore, when the refresh is carried out, the amount of transmitted information for part or all of the channels other than the refreshed channel is compressed and, conversely, the amount of transmitted information for the refreshed channel is increased by the compressed amount and allocated. Thus, even if the channel is switched at the receiving side, the decoded image for the newly-selected channelcan be promptly reproduced.

Title: Method and apparatus for equalization in fast varying mobile radio channels
Inventor: FUKAWA KAZUHIKO
IPC: H04L25/03
Filed: 1992-04-06
Abstract: In an apparatus for equalization in fast varying mobile radio channels, a signal generating circuit outputs a signal sequence undergoing transition at a predetermined period and corresponding to each state transition and a signal sequence corresponding to the path of each state transition.  An adaptive filter receives the signal sequence corresponding to each state transition and outputs an estimated signal for each state transition. The apparatus also includes state estimating circuits for performing state estimation by using the square of an estimation error obtained by subtracting each estimated signal from a sampled signal, and a control circuit for controlling the tap coefficient of the adaptive filter by using the RLS algorithm in order to minimize the square of  the estimation error.

Title: Method and apparatus for combined cylindrical and spherical eye corrections
Inventor: SCHIMMICK JOHN
IPC: A61F9/00
Filed: 1992-07-14
Abstract: A method for performing concurrent spherical and cylindrical corrections to the corneal surface of the eye to reduce myopia and astigmatism. A laser beam irradiates the corneal surface via a variable diameter iris and a slot produced by a pair of translatable blades. The width of the slot and the diameter of the iris are varied as the laser is pulsed to produce a toric ablation of the corneal surface. Alternatively, the laser beam is passed through a succession of apertures in a tilted variable aperture element to produce toric ablation. The total number of laser pulses required to effect both types of correction is equal to the number required for the spherical correction alone, reducing the laser power and the procedure time. The toric ablation produces no steep end walls as with standard cylindrical ablation procedures, thereby eliminating hyperopic shift and minimizing flattening along the ablated cylinder axis.
