[Also in Group XXXII] In a mounting of the kind in which a screwthreaded bolt 3 is rotatable in a threaded sleeve which is fixed in a surrounding bush 2, the sleeve is in the form of a helical spring 1, which has a greater diameter (when relaxed) than that of the bush 2. As shown, the invention is applied to the mounting of a leaf spring eye 2 on shackle plates 4. The spring is given a rotation in order to contract it for insertion into the eye 2. The spring 1 may alternatively be of triangular, square, rectangular or trapezoidal cross-section material. The spring 1 is formed with notches 5 for a screw driver used to turn the spring when inserting it into the leaf spring eye. The spring 1 is retained in the eye by the engagement of its end coil with a detent at 6. Alternatively (Figs. 3 and 4. not shown) the leading coil of the spring 1 may be rabbeted to engage the edge formed between the end-face and bore of the leaf spring eye. The end and leading coils of the spring may be bent inwards, so that the tip of each of these coils bears against the pin 3. This damps lateral movement of the pin 3. The spring 1 may be secured in the leaf spring eye by a cement which has the property of chemically uniting them by oxidation.

Abstract: Phenolic resins are produced by mixing a light metal oxide, 1 mol. of an aldehyde, hexamethylenetetramine or a ketone and more than 1 mol. of a phenol or meta-substituted phenol, the pH of the mixture being between 4 and 7, and heating the mixture.  The term "light metal oxide" is defined to include an oxide or hydroxide of an alkali metal, alkaline earth metal, zinc, magnesium or aluminium.  Suitable phenols are phenol, m-cresol or m-xylenol. The final reaction temperature is preferably above 135 DEG  C. Aldehydes mentioned are formaldehyde, acetaldehyde or benzaldehyde.  Acetone is mentioned as a ketone.  Excess phenol may be distilled off for re-use after the condensation, and the remaining resin may then be reacted with more formaldehyde.  In the example, phenol and formalin were mixed and zinc oxide added to produce a pH of 4.7.  The mixture was refluxed, and then heated to distil off water.  Excess phenol was removed by steam distillation with vacuum, and the intermediate resin heated with more formalin and zinc oxide.  The product was mixed with hexamethylenetetramine, lime, stearic acid, pigment and wood flour in usual way to form a moulding powder.
