Title: Improvements in or relating to levels and clinometers
IPC: G01C9/00
Filed: 1939-03-03
Abstract: 525,950. Indicating - apparatus ; inclino - meters ; barometers. CUTHBERT, W. A., and WARNER, W. C. March 3, 1939, No. 7072. [Class 106 (iv)] [Also in Group XX] In a clinometer, barometer or other measuring instrument, giving an amplified pointer movement without the employment of step-up gearing or other multiplying mechanism, a weighted indicator pointer 1. Fig. 2 or Fig. 3, is freely pivoted on an inclined spindle 9 or 20 normally situated in a vertical plane, any deviation of the spindle from the vertical plane resulting in the swinging of the pointer through an arc in excess of the angle of such deviation. In Fig. 2 which is a plan view of a level or clinometer, should the base 12 be tilted so that the spindle 9 leaves the vertical plane the pointer 1 swings through a greater angle. The degree of sensitivity may be regulated by adjusting the inclination of the spindle 9 by means of a micrometer screw 13 which imparts a rotation to a shaft 10 carrying the spindle 9. According to Fig. 3, as adapted for indicating changes of barometric pressure, a bellows 16 moves the spindle 20 out of the vertical plane to operate the pointer. The device may be arranged to give an audible instead of a visible indication, or may he arranged to fire a gun on board ship by completing or breaking an electric firing circuit.

Title: Improvements in or relating to the production of bulked yarns
Inventor: TARKINGTON THRRY WESLEY
IPC: D02G1/18
Filed: 1963-02-21
Abstract: A dimensionally stable high bulk yarn of substantially uniform cross section is composed of staple fibres blended together, some of the fibres having a fixed potential shrinkage while other fibres have a variable potential shrinkage less than the fixed shrinkage, so that on subjecting the yarn to a heat-shrinkage treatment, the fibres having the fixed shrinkage form a load-bearing core, and the other fibres spiral outwardly from the core with varying amplitude corresponding to the variable shrinkage.  In one example the yarn is formed from a tow to which had been imparted appropriate ranges of variable and constant potential shrinkage in recurring cycles along its length, by either partially shrinking a tow of initially constant potential shrinkage by passing the tow through a relaxing zone and varying the feed or take-up speeds, or by giving a tow a temporary variable stretch corresponding to the desired ranges of potential shrinkage.  The yarn may be of polyacrylonitrile, a copolymer of acrylonitrile with another monomer-a list of suitable monomers being given-, a blend of polyacrylonitrile with another polymeric material, polyethylene terephthalate, polyamides and copolymers of various amides, vinyl polymers, polymers and copolymers of ethylene and halogen substituted ethylene, and polyolefins.
