Title: Cardboard box forming machine
Inventor: BOIX JAEN JOSE
IPC: B31B3/46
Filed: 1992-06-30
Abstract: A box forming apparatus for forming a box from a pressed cardboard blank which has been introduced on a forming matrix. The apparatus has two rectangular end plates joined together by a bridge by means of a guide and bolt system in each plate. The guide and bolt system permits variation and adjustment of the height of the apparatus with regard to the machine support. Two winged plates are pivotally attached between the end plates, the winged plates pivoting freely without the aid of pistons or springs. The respective axes of rotation of each of the wings is located at their respective top edges. The pivoting of the wings is delimited by round profiles, or stops, located on the end plates at two separate locations. One set of the stops prevent motion inward towards the center of the end plates, while a second set of stops prevent motion outward away from the center of the end plates. The wings have a bevelled bottom edge for relatively free sliding motion as the wings contact the cardboard blank.

Inventor: DUTRO LYNN R
IPC: H02K17/08
Filed: 1993-01-08
Abstract: A single-phase half-pitch capacitor induction motor capable of being varied in rotational speed between a low rotational speed and high rotational speed.  The motor includes a main winding connected across a single-phase electrical power source and an auxiliary winding connected in parallel with the main winding.  A first phase shifting capacitor is connected in series with the auxiliary winding.  A second capacitor is connected in parallel with the first capacitor and a variable resistor is connected in series with the second capacitor. By increasing and decreasing the resistance, overall capacitance in series with the auxiliary winding is increased and decreased and the rotational speed is, thus, also varied.  A single pole, single throw switch or a thermistor can be used instead of a variable resistor for different applications.
