Patent CA-2043587-A1 (CA)
Title: Universal telephone handset interface
Inventor: HANON DAVID O
IPC: H04M1/60
Filed: 1991-05-30
Abstract: UNIVERSAL TELEPHONE HANDSET INTERFACE                  ABSTRACT OF THE DISCLOSURE       An apparatus 10 is employed for interfacing a telephone handset 18 to a telephone network.  Typically, a telephone handset has one of a variety of different microphones disposed therein, such as carbon, electret, etc., where each type of microphone has a different output level and impedance. Conversely, the telephone network with which the microphone is to be interfaced has a preselected input impedance and signal requirement intended to match only one type of microphone.  The apparatus 10 includes a plurality of switches 82, 84, 86, 88 and resistors 90, 92, 94 that are manually switchable into the circuit either separately or in combination to match the output impedance and signal level of the microphone with the input impedance and signal level of the telephone network.  Alternatively, in a second embodiment of the instant apparatus, a variable resistor is employed to match the output impedance and signal level of the microphone with the input impedance and signal level of the telephone network.

Title: Direct vision prostate balloon catheter
Inventor: RUDNICK JAMES J
IPC: A61M25/10
Filed: 1991-06-18
Abstract: A direct vision prostate balloon catheter for treating benign prostate hyperplasia to dilate a prostate gland to reduce constriction of the urethra is provided. The catheter includes an expandable balloon and a sighting device such as a cystoscope telescopic, lens proximal to the veru montanum to assist in properly positioning the expandable member. The balloon can have a thickened distal end and an overlapping proximal end to prevent undesirable migration during expansion. Alternatively, the balloon can be mounted on two tubes, one slidable axially inside the other to control balloon extension during expansion of the balloon. This construction provides advantages such as proper dilation of the prostatic urethra and helps prevent undesirable dilation of the external sphincter.

Title: Rail switches
Inventor: WRIGHT MARK M
IPC: E01B25/12
Filed: 1991-08-30
Abstract: ABSTRACT OF THE DISCLOSURE Two-way rail switches (22) and three-way rail switches (24) for a monorail system (20) utilize a flexible coupling (36, 38) to provide for pivoting a rail member (34, 35) between aligned positions with branch rail lines (28, 30, 32).  The flexible coupling (36, 38) connects a main rail (26) to the pivoting rail member (34, 35) so that a continuous rolling surface is formed, facilitating gravity feed.  Movement between positions is controlled by actuation of pneumatic cylinders (64) having shafts (68) which may be connected in series to push a beam (46, 48) between positions so that the rail member (34, 35) is aligned with the branch rails.  A glide track (52, 53) with a wear plate (54) guides the beam (46, 48) between aligned positions.

Title: Dimensional inspection process of medical ampules
Inventor: DASSLER HANS-ULRICH
IPC: G01B11/02
Filed: 1992-04-03
Abstract: To carry out an entirely automatic dimensional inspection process of medi-cal ampules, the ampules (1) are cyclically transported in the horizontal position on a chain conveyor (30) through an opto-electronic inspection station (10).  The ampules are lifted  from the chain  conveyor to be inspected and illuminated  bytransmitted light in a  direction normal to their longitudinal axis by a diffuse light-ing source (11).  In the case of  OPC-ampules, the ampule is retated around its lon-gitudinal axis during inspection.  The light that shines through the ampule is repro-duced on the opto-electronic converter (photodiode line) of a camera system  (12) which converts the reproductions into electric video signals.  These video signals are evaluated on the basis of the intensity variations caused by the inspected am-pule, in order to generate measurement values for the desired  ampule  dimensions as well as, if necessary, for deviations from the standard  ampule dimensions.
