Title: Clipping device for pile fabrics - has clipping roller and fabric support comprising several plates movable towards roller
IPC: D06C13/00
Filed: 1974-12-24
Abstract: A pile fabric passes over a support edge defined by a series of pile plates arranged beneath a clipping roller the support plates being slidable in a support so as to adjust the position of the plates relative to the clipping roller and so control the line of contact between the pile of the fabric and the clipping roller. Each plate pref. has a rear extension which is acted on by a series of springs via the intermediary of a flexible band extending along the rear extensions of the plates to bias the plates towards the clipping roller and a chamfered camming element, is movable by a lead screw along the plates such that is acts on their rear extensions and moves the plates away from the clipping roller against the action of the springs in the region of the camming roller and so move the corresponding region of the fabric away from the clipping roller. A uniform line of contact of the fabric with the clipping roller can be achieved since a reasonably uniform spring biassing is exerted on the plates irrespective of the wear of one or two springs.

Title: Talking doll noise generation mechanism - has governor tilting gramophone spindle free on stopping clockwork drive mechanism
IPC: G11B33/06
Filed: 1976-02-06
Abstract: The clockwork mechanism drives a governor and a gramophone disc spindle tilting in an elongated hole. The swing motion of the pick-up arm and needle is opposed by a spring bearing against a sound-transmitting diaphragm. At a particular stage the spindle is tilted to free the needle from the disc grooves, whereupon the arm returns to the starting position. The clockwork mechanism (24) drives the disc (4) via an intermediate wheel (26) fixed to the spindle (2)7 and other wheel s (18), and is stopped after the disc has been played. The governor has a rotary flywheel disc driven by the intermediate wheel, and whose position and direction of rotation in relation to the elongated hole and the spindle are such that tilting of the latter occurs as a result of the inertia force of the disc when the clockwork mechanism is stopped. Simultaneously the spindle and flywheel disc are uncoupled. The spindle tilts back into the working position when the clockwork mechanism is set going again after rewinding.

Title: Proportioning device for powdered prods. - for continuous distribution of flocculating additive to water supply
Inventor: SEILLER LESBROS
IPC: C02F1/68
Filed: 1976-07-16
Abstract: Proportioning device for pulverulent prods. is intended for the continuous distribution of powdered flocculating additives to a water supply before filtration, making use of an ultrasonic vibrator. The device consists of a hopper with a vibrating plate. A potentiometer increases or reduces the amplitude of the vibrations and hence the rate of delivery of the dry prod. Pre-regulation is obtd. by means of a diaphragm and the additive falls as discrete particles intot he receiving fluid in the diluting mixer with its conical extension. Water under pressure enters at two points. The inlets are arranged tangentially and create a vortex in the mass of the receiving liq., thus completing the mixing of the additive. The mixt. leaves by the pipe with its control valve. Distribution of a perfectly balanced proportion of additive is homogeneous and the mixt. can be used for any further operation, e.g. filtration. There are no moving parts so maintenance is extremely reduced and the reliability of the device renders it applicable to the public service.
