Patent GB-867875-A (GB)
Title: Preparation of hydantoic acid-formaldehyde resins
IPC: C08G12/26
Filed: 1957-09-13
Abstract: Resins are prepared from a hydantoic acid and formaldehyde, preferably by refluxing in a solvent in presence of a catalytic amount of acid, e.g. 85% phosphoric acid.  The hydantoic acids or mixtures of such acids are prepared by treating an a -amino acid or mixture of amino acids produced by hydrolysis of a protein either with urea in alkaline solution or with potassium cyanate. Proline and hydroxy-proline yield ringcontaining hydantoic acids. The resins may be mixed with a urea-formaldehyde resin.  In Example 1, dl-leucine was reacted with alkaline urea to produce iso-butyl hydantoic acid which was reacted with aqueous formaldehyde and phosphoric acid.  The oily product was mixed with urea, formaldehyde and phosphoric acid to give a solid mixture of the two resins; (2) a protein hydrolysate left from a glutamic acid extraction was treated with urea to give a mixture of hydantoic acids which was reacted with formaldehyde to give a resin; (3) is similar to (2).  Specification 867,876 is referred to.

Title: Improvements in or relating to gramophones
Inventor: MURRAY JOHN KEITH

Abstract: 1,082,246. Gramophone pick-up supports. MARCONI INSTRUMENTS Ltd. April 28, 1964 [July 24, 1963], No. 29319/63. Heading G5R. A pick-up arm is pivoted about a horizontal torsion wire, one part of the wire being fixed to a support and another part to the pick-up arm so that the arm pivots in a vertical plane by twisting the wire and the stylus pressure is determined by the torsion of the wire. Fig. 2 shows a cross-section of a pick-up arm 1 provided with a laterally extending tube 10 closed by end caps 12 and 13 to which the ends of a torsion wire 11 are soldered. The centre of the wire is clamped by a clamp 14 which is pivoted about a vertical axis in a stand 4. With the tensioning nuts 15-18 slackened so that the wire is unstrained, counterweights (not shown in Fig. 2) are adjusted to balance the weight of the pick-up and bring the centre of gravity of the pick-up arm into a vertical plane through the pivot axis, and preferably on the axis. The wire is then tensioned by tightening nuts 15- 18, and the caps 12 and 13 are rotated by equal amounts and locked by grub screws 19 and 20 to give a desired stylus pressure. Since the pressure is determined by the wire it is not affected by shock. Nylon bushes 21-26 are provided inside the tube 10 to prevent undue movement of the wire, and the tube may be filled with a silicone damping compound to damp torsional vibration of the wire. In an alternative construction, Fig. 3 (not shown), the wire is contained in a tube attached to the pick-up arm support and a clamp attached to the centre of the wire bears on the end of a screw extending through the pick-up arm. Rotation of the screw provides a fine adjustment of the stylus pressure.
