Patent CA-2089478-A1 (CA)
Inventor: SCHORMAN ERIC R
IPC: G10L13/04
Filed: 1991-10-01
Abstract: An electronic system and a method substantially eliminates any delays caused by buffering of a signal containing speech. The electronic system comprises a receiver for receiving signals (16), a buffer (26), coupled to the receiver, a buffer controller (28) coupled to the buffer, and an audio section (32) for presenting signals received to a listener. The method comprises the following steps. The receiver receives an input signal representing speech, and produces an output signal representing the input signal after a delay intentionally introduced in the system. The delay corresponds to the length of the buffer. The buffer stores the input sig-nal in the buffer at an input rate, and produces the output signal at an output rate. The buffer controller determines whether the delay or buffer length is greater than a predetermined threshold, and analyzes at least a portion of the input signal stored in the buffer to determine which parts of the input signal may be removed without substantially deterioration of the signal quality accord-ing to at least one predetermined criterion, when the buffer length is greater than a predetermined length. The buffer controller then deletes at least some of the parts of the input signal stored in the buffer that comply with the predetermined criterion.

Title: Recovery of zinc values from a solution containing hydrocyanic acid
Inventor: KIDBY DENIS K
IPC: C22B3/44
Filed: 1993-02-25
Abstract: RECOVERY OF ZINC VALUES FROM A             SOLUTION CONTAINING HYDROCYANIC ACID     ABSTRACT OF THE DISCLOSURE     The present invention, relates to the recovery of zinc values from an acidic solution containing hydrocyanic acid.  The zinc is recovered as complex zinc cyanide anions which may, if desired, be recycled for the (selective) preliminary removal or separation of adsorbed copper values from an (strong or weak base) anion exchange material, the anion exchange material additionally being loaded with adsorbed cyanide complexes of precious metal values such as gold and silver.  The invention, further relates to the recovery of cyanide values associated with copper cyanide complexes which are adsorbed on or taken up by an (strong or weak base) anion exchange material; the recovered cyanide values, for example, being available for recycling to a cyanide leach stage for leaching additional metal values from an ore or the like.
Patent CA-2091629-A1 (CA)
Inventor: FUJI HIROSHI
IPC: G11B7/005
Filed: 1993-03-15
Abstract: A  waveform  shaping  circuit  has  a  waveform equalizer, an envelope equalizer, a slice signal generator, and  a  comparator.    The  waveform  equalizer  serves  to waveform-equalize an optical readout signal, and compensates for interference between code bits.  The envelope equalizer serves  to envelope-equalize  the  output  signal  of  the waveform equalizer.  The envelope-equalized signal is sent from the envelope equalizer to the slice signal generator.          The slice signal generator stabilizes the slice signal.  The outputs of the waveform equalizer and the slice signal generator are applied as inputs of the comparator.   The comparator serves to compare both inputs with each other and produce a binary reproduction signal therefrom.

Title: Motor-Vehicle Parking System
Inventor: COLSMAN ALFRED
IPC: E04H6/18
Filed: 1993-12-22
Abstract: A system for parking motor vehicles exhibits one or more autonomous parking units (S) which are, in outline, in the form of a sector of a circle. Each unit of this kind is assigned a vehicle lift (10), as mechanical conveying means, having a vertical guide (11) arranged in the region of the vertex of the sector and having a projecting vehicle platform (12) which can pivot over the angle of the sector. The task of the lift (10), within the parking unit (S), is to transport the vehicles vertically and horizontally between an entrance/exit level (1) and parking bays which are located on parking levels beneath and/or above the level (1); the lift (10) is further set up for the radial shifting of the vehicles. Each parking unit (S) is, moreover, assigned means for turning in each case one vehicle on the spot, e.g. one or more rotary platforms (8) on the entrance/exit level (1). The vehicle standing surface (9) of each rotary platform can be optionally lined up in an entrance position, an exit position or such that it is radially aligned with the vehicle platform (12) of the lift. A facility of this type adapts (computer-controlled) very flexibly to various operating situations. When driving out, the vehicles can leave the facility such that they can drive forwards straight away. By virtue of a modular construction method, it is not only round facilities which can be produced, but - always having the same units (S) - also other facility outlines which are adapted to the relevant situation. <IMAGE>

Title: Groove width trimming
Inventor: JERMAN JOHN H
IPC: H01L21/302
Filed: 1993-08-18
Abstract: A method for making a groove (205) of a precise width in a substrate (210). The groove may have any cross-sectional shape. The groove is formed by initially etching the substrate. The groove width (W) is then measured. The measured groove width is compared to the desired groove width (W2). Oxide is grown on the substrate in the region of the groove to adjust the width of the groove. The oxide may or may not be grown with the original etchant mask left on the substrate. Depending on whether it is desired to increase or decrease the groove width, the oxide is or is not removed.  The process for increasing or decreasing groove width may be repeated any number of times as necessary to achieve a proper groove width. For many applications, the groove will be covered with a plate or other type of cap to define a channel as used in flow restrictors.
