Title: Removable loom fabric beam - has mechanism to detach beam end centre sleeves with rack and pinion system to move the beam into time transport position
Inventor: GENDELMAN MICHAIL ABRAMOVIC
IPC: D03D49/20
Filed: 1989-07-06
Abstract: The removable fabric winding beam assembly, on a loom, has a reversible electro-motor and transmitters for the operating position of the beam and to move it into given settings, within the electrical control circuit for the motor. The beam mountings are in the form of centre sleeves which can be pulled in and out to the sides after they have been detached from the beam through a kinematic connection with the motor while the mechanism to slide the beam from the working position to the transport position is operated by the pinion drive working on racks. The racks run parallel to each other on the loom body-below the ends of the fabric beam to move it into the position for onwards transport. Cogwheels are kinematically bonded to the electromotor, and blocks hold the beam in place which work--together with the racks as the centre sleeves are separated from the beam by a sliding mounting. ADVANTAGE - The mechanism gives a mechanical fabric beam removal operation, relieving the operative of manual work in detaching it, whether the loom has a horizontal or vertical feed line.

Title: Motor-cycle with combined saddle and pinion seat - is swung upwards in event of collision
Inventor: BERG F ALEXANDER
IPC: B62J27/00
Filed: 1990-04-28
Abstract: A motor-cycle is equipped with a combined saddle and pillion seat (6). The front end of the saddle is supported on rollers (10) whilst the rear end of the pillion seat is supported by a swinging arm (7).
