Title: Hand-loom - with pedal-operated heald lifting system sited beneath the loom
IPC: D03D29/00
Filed: 1979-04-25
Abstract: Handloom has a pedal-operated heald-lifting system sited beneath the loom. The lift is effected by pulleys attached to a hardness, and a rope connecting the pedal-pulls to the heald frame. The effort of lifting is less demanding on the weaver than on a hand loom worked by overhead pulleys, making the work pleasanter and faster. The space above the loom is uncluttered, and warp insertion is easier. Pedal space is plentiful.

Title: Automatic document reader or imprinter - uses lateral moving read or write head to accommodate documents of variable thicknesses
Inventor: CHAMBOLLE JACQUES
IPC: G06K13/02
Filed: 1979-08-30
Abstract: The automatic reading or marking of documents of variable thickness requires movable read/write heads and a movable surface against which these heads can work. Documents are passed vertically downwards between a sprung roller (32) and a motor (30) driven roller (25). A micro switch (71) activated by a passing document controls the supply roller motor and also initiates the horizontal closing of the gap between the read/write head (16) and its anvil drum (21). The document is processed then released to be picked up by another motorised roller and carried away. A logic circuit (81) holds the document in place until all necessary data has been read or written on it.

Title: Mouth operated controller for instrument keyboard - has harmonica-like configuration with slidable actuated pistons selectively contacting terminals which cause activation of key
IPC: G10F3/00
Filed: 1980-07-07
Abstract: The remote control for a piano or organ enables a person to play the instrument by mouth and comprises a harmonica-type mouthpiece formed with a number of parallel bores in which respective pistons are slidable. The pistons are maintained centrally in the tubes by weak coil springs and carry brass contacts at each end to bridge fixed contact pairs formed at each end of the tubes. Blowing into a tube moves the piston to one end to close the end contact pair while sucking draws the piston to close the opposite end contact pair. The contacts control electromagnetically operated levers in turn acting on the piano or organ keys, each key having a respective lever drawn down onto the key against a spring by an electromagnet. The control of keys can be varied by adjusting the connections between the tube contacts and the electromagnets.
