Patent CA-2139810-A1 (CA)
Inventor: CHISHIMA MASAMITSU
IPC: H01R11/01
Filed: 1994-03-01
Abstract: This invention aims to provide a joint connector which makes it easy to insert a tool therein upon detaching a female terminal therefrom and prevents a locking finger from being deformed and impacted.  A locking finger (1d) is arranged inwardly below an outer face of a side wall (1b) of a connector housing (1).  The side wall (1b) is provided on an outer face with an outwardly slanted portion (1h) which inclines and extends outwardly from an end face (1e) opposite to a distal end of the locking finger to the outer face.  The slanted portion (1h) guides a tool (5) to insert it into the connector housing (1).  An upper end of the slanted portion (1h) becomes a fulcrum for the tool and thus a distance between the fulcrum and an acting point of the tool becomes longer.  In order to prevent a short-circuit due to a leak between branched circuits, a coupling portion (25a) of a shorting plate (60) abuts on a distal end of a side wall (12) of the connector housing (1) so that the distal end limit an insertion position of the shorting plate (60).  The connector housing (1) includes first side walls (12a, 12b, 12d) the distal ends of which abut on the coupling portions (25a) of the shorting plates (60A, 60B) for a divisional shorting use and a second side wall (12c) the distal end of which abuts on the coupling portion (25a) of the shorting plate (60) for an all pole shorting use.  In order to avoid interference upon connecting alternately electrical wires directed in opposite directions, a joint chamber (115) is provided between piled terminal accommodating chambers (13), which are communicated with the joint chamber through apertures (112).  The shorting plate (60) is inserted into the joint chamber (115) to confront a given aperture (112).  A female terminal (2) is provided with a tongue piece (22c) which elastically contacts with the shorting plate (60) through the aperture (112).  When the terminal (2) is inserted to the terminal accommodating chambers (13) having openings (131) directed alternately in the reversed directions, the tongue piece (22c) contacts with the shorting plate (60) to electrically interconnect them.  Since the chamber (13) may be arranged through the aperture (112) adjacent to the joint chamber (115), the chamber can be directed in any direction.  In order to use electrical wires having different diameters, the connector housing (1) is provided with terminal accommodating chambers (13) having different sizes so that the housing can simultaneously accommodate electrical wires (91 and 92) with large and small diameters. Since a contacting portion (22) of each terminal (2) has a common shape, the chamber (13) can accommodate either large or small diameter wires.

Title: Dough treating and dispensing method and apparatus
Inventor: CUMMINS DONALD L
IPC: B01F7/00
Filed: 1995-02-10
Abstract: Dough intended for use in producing bakery products is homogenized and advanced to extrusion nozzles where it is cut into successive pieces that fall onto a moving conveyor.  The pieces are of precisely uniform weight because a constant pressure is maintained on the dough as it is forwarded by a metering pump toward the nozzles.  Apparatus for achieving such result includes an auger, a developer positioned downstream from the auger, and a transition chamber fed by the developer and located upstream from the metering pump.  A pressure-measuring monitor serves to control the rotational speed of the auger, thereby maintaining the dough under constant pressure within the apparatus.

Title: Rope guide system for an aerial ropeway, particularly a circuital aerial ropeway
Inventor: EGLI ERNST
IPC: B61B12/10
Filed: 1995-02-27
Abstract: In a double-haulage aerial ropeway the ascending lane 1 and the descending lane 2 are each formed by two haulage ropes 1I, 1II, 2I, 2II guided parallel side by side at the same height in the region of the haulage path F. A single endless haulage rope, crossed once by means of deflector wheels 61, 62 to form an inner rope loop I and an outer rope loop II, forms by its rope loops synchro-nous regions 1I, 1II and 2I, 2II for the coupled vehicles 3. The driving station T has two laterally offset, driven reversing wheels 41, 42;  at the reversing station B at least two traction-driven reversing wheels 5 are arranged to support the two rope loops I,  II.   The reversing wheels  of  the  one  station  are  mounted  in  a  fixed position, and those of the other station are conjointly stayed.  Inner and outer deflector wheels 6, 7 bring the four haulage ropes, which are guided parallel, at both stations to the respective associated reversing wheels 4 and  5  in  planes  which  are  set  at  an  angle,  with offsetting in height.  The two inner deflector wheels 61, 62 at the station associated with the driving wheels 41, 42 are inclined in order to form the rope crossing point X and to change the running grooves in the driving wheels 41, 42.  The first of the traction-driven reversing wheels 51 and the two inclined deflector wheels 61, 62 support the inner rope loop I.  Two additional reversing wheels 52,  53,  laterally offset relative to one another and arranged  symmetrically  to  the  first  traction-driven reversing wheel 51, together with the two driving wheels 41, 42, preferably support the outer rope loop II. The two driving wheels 41,  42  are driven independently of one another by a master machine 81 and a slave machine 82 and synchronized for exact synchronism of the haulage rope in the two rope loops I, II. - Funitel -
