Title: Forming non-woven fibrous material
IPC: D21F1/02
Filed: 1974-11-26
Abstract: In a method of making non-woven fibrous material such as paper, the papermaking stock as it is being delivered to the foraminous support of a papermaking machine has air under pressure introduced into it to produce foaming of the stock and the stock is subjected to turbulence. This is effected by providing the head-box of the papermaking machine with a slice the body of which includes a slot through which the stock flows to the foraminous support and which is shaped to impart turbulence to the stock. The body also includes an air supply passage which communicates with the slot to introduce the pressurised air into the stock.

Title: Chair seat mount which permits the seat to tilt forward
IPC: A47C7/14
Filed: 1978-05-08
Abstract: The seat of a chair is mounted on a post or other supporting member by a seat mount which permits the seat to tilt forward (front end down) to a forward and downward rake of about 41/2 DEG . A bracket connected to the seat and located under generally the center of the seat pivots on an axle that is received and supported by a mounting plate rigidly fastened to the supporting member. Springs compressed between the mounting plate and the bracket restrain the seat from tilting down, and co-engageable stop surfaces associated with the bracket and mounting plate limit the extent of tilting of the seat (both forward and backward rake, when the latter is provided for). By joining the mounting plate and bracket by parallel front and rear axles fixed to the bracket and arranged to disengage axle-engaging surfaces on the plate, or vice versa, the seat can tilt both forward and backward in this mode, the seat pivots or rocks on one axle, and the other axle disengages the axle-engaging surface. An optional movable blocking element can be included to disable the rearward tilt mode when desired.

Patent ES-485852-A1 (ES)
Title: Method of agitating nonnsolidifying portion of casting strand
IPC: B22D11/10
Filed: 1979-11-08
Abstract: The cast strand (5) is formed in a mould (3) and the stirring of the unsolidified regions (6) is performed by means of one or more electromagnetic stirrers (7).
