Title: Improvements in or relating to sealing means for screw threads
IPC: F16B39/34
Filed: 1956-10-03
Abstract: 830,358. Joint-making packing. FLICKREEDY CORPORATION. Oct. 3, 1956 [Jan. 16, 1956], No. 30113/56. Class 122 (3). [Also in Groups XXV and XXVIII] Means for sealing screw-threaded pipe or other joints comprising a metal nut 27, Fig. 7, consists of an annular ring 30 of resilient plastic material which is disposed in an annular space at one face of the nut provided by an outer ring portion 28 of the nut and is screwthreaded internally in continuation of the threads in the nut so that, before assembly, its threads have a smaller inner diameter than those of the nut and, when assembled on the screw threaded part to be sealed, its threads extend inwardly to embrace tightly these threads; the ring 30, which may be of tetrafluoroethylene, has a generally flat unobstructed outer bearing face extending outwardly beyond the metal ring 28 for contacting the face 26 of a part 17 of the joint. The threads of the ring 30 are formed after the latter is inserted in the hut, preferably to the extent of 1¢ or 2 turns, by the same tap as used for the nut but not to the full depth. The outer diameter of the plastic ring 30 is larger than the internal diameter of the recess 34 in the nut so that the former is installed under pressure. Knurling on the inner face of the retaining ring ensures the locking of the two rings. The face 26 may be chamfered around the threaded hole so that leakage of fluid under pressure to the space so formed will exert an upward force on the plastic ring to tighten the seal. Fig. 13 shows a modification in which the plastic ring 49 is of inverted U-section and is retained in the metal ring by a lip 46 which fits within a recess 51 formed in the retaining ring. When installed the plastic ring is subjected to compression on all faces, including those of the chamber 54 formed by the U-shaped recess which is sealed by the end contact face 47; this chamber accumulates leakage pressure from the coupling threads, thus tending to spread the arms of the ring outward into closer engagement with the metal parts of the coupling.

Title: Process for preparing 'unsaturated polyesters
IPC: C08G63/553
Filed: 1960-09-05
Abstract: In a process for preparing unsaturated polyesters which contain as glycol component an endomethylene-tetrahydrophthalyl glycol component, an unsaturated double bond containing first glycol or an unsaturated triple bond containing first gycol is reacted with the anyhdride of a saturated or unsaturated dicarboxylic acid in the molecular proportion of 1:2 to form the corresponding acid glycol ester and then cyclo-pentadiene or homologues or substitution products of cyclo-pentadiene are reacted by addition reaction to the unsaturated bonds and the resulting addition product is condensed with an unsaturated dicarboxylic acid and a second glycol to give a polyester. Instead of cyclopentadiene there can also be used dicyclopentadiene if the reaction temperature is such that splitting of the dimer into monomeric cyclopentadiene takes place. As dicarboxylic acid anhydrides there are specified maleic, tetrahydrophthalic, dimethyltetrahydrophthalic and hexachloroendomethylene-tetrahydrophthalic anhydrides.  The polyesters can be mixed with a vinyl monomer, e.g. styrene and a peroxide catalyst for use as casting, lacquer and laminating resins. In examples (1) butene-2-diol-1,4 and phthalic anhydride are reacted to give the diester which is then reacted with cyclopentadiene (1 mol).  The product is then heated with maleic anhydride (1 mol) and glycol (2 mols) to give the polyester; (2) butene-2-diol-1,4 is used in a similar process; (3) methylcyclopentadiene and (4) hexachlorocyclopentadiene are used n similar processes to that of example (1).  The products of (3) and (4) are mixed, for use, with styrene.  Specification 830,794 is referred to.

Title: Improvements in or relating to transductors
Inventor: WILKINSON SIDNEY
IPC: H03K19/16
Filed: 1967-07-03
Abstract: 1,224,880. Non-contact making relays. GENERAL ELECTRIC CO. Ltd. 3 July, 1968 [3 July, 1967], No. 30628/67. Heading H3B. [Also in Division H1] In order to cancel out effective mutual induction between any two windings of a multicore transductor during balanced conditions and between the primary winding and any one of a plurality of control windings, the primary, secondary and control windings are disposed as shown in the Figure. Four identical ring cores 1, 2, 3, 4 are arranged in a square formation on a square insulating board having four holes in alignment with the bores of the ring cores and a further hole lying centrally between the other four. The windings are threaded through the apertures so that each turn of each winding is coupled to every core and in such a manner that every pair of windings is wound in one relative sense on two of the cores and in the opposite relative sense on the other two. An A.C. in the primary winding and no control current in either control winding induces an e.m.f. in the various parts of the secondary winding but since the secondary winding is wound as shown there will be no net e.m.f. across the secondary winding. Similarly there will be no net e.m.f. across the control windings. If a D.C. exists in one of the control windings all of the cores will be saturated to a greater or less extent but all equally so that the various induced e.m.f's are still balanced over each winding giving a net zero output. If both control windings carry a D.C. two of the cores will have added control magnetomotive forces and two balanced and cancelling magnetomotive forces resulting in a net output voltage being obtained across the secondary winding. The induced e.m.f's in each control winding remain balanced since if cores 1 and 3 are unsaturated both control windings have parts in opposition and similarly in the case of cores 2 and 4 being unsaturated and there is no coupling into the control circuits. If any turn should become short or open circuit the device will fail safe. The device may be considered as a two input AND gate and a greater number of inputs can be accommodated by connecting the output of one device to supply one input of another and so on in cascade, each device providing a further input requiring to be energized to produce a final output. Amplitude modulation of the output voltage may be obtained by using D.C. for one control winding and a low frequency A.C. for the other.
