Title: Improvements in or relating to the manufacture of sheet material composed of unwovenresin-bonded fibrous material
Inventor: CROCOMBE FREDERICK FRANCIS
IPC: D04H1/00
Filed: 1953-07-03
Abstract: 762,096. Fabrics composed of adhesively united fibres or threads. BOULTON PAUL AIRCRAFT, Ltd. July 5, 1954 [July 3, 1953], No. 18474/53. Class 140. A method of manufacturing sheet material composed of unwoven bonded fibrous material comprises impregnating with uncured synthetic resin a continuous thread or threads, or roving, during the passage of the thread, threads or roving to a former on to which the impregnated material is wound, curing the whole of the wound mass under pressure while on the former, and then cutting open the cured mass and removing it from the former. The thread or roving may be of glass and the resin may be a polyester resin. Multi-layer material may be formed wherein the threads of one layer are disposed at an angle to those of the adjacent layer or layers by cementing together single layers after curing and removing from the former, or by winding the threads on the former in a way such that the threads in one layer are disposed at an angle to those of the adjacent layer or layers. Glass thread may be treated before impregnation with a coupling agent such as methacrylatochromic chloride or an organosilicon compound. As shown, a continuous glass thread 1 is passed through an electric heater 2, then by means of rollers through a bath 5 of coupling agent, and thence through an electric heater 8. It next passes, by means of rollers, through water baths 9 and 9<SP>1</SP>, wherein clean water enters through pipes 14 and 141 and flows out through outlets 15 and 151, and then through an electric drier 16. Thence it passes, by means of rollers, through the impregnating bath 17 containing polyester resin and finally over a traverse 18 on to a former 19 rotated on a motor-driven winder (not shown). When a desired thickness of material has been wound on to the former the latter is removed from the winder and placed in a curing mould. It may e.g. be placed on a heating platen and covered with a flexible sheet of rubber connected to a vacuum pump.

The photochemical addition results in the formation of a mixture of 4,5-cyclobutano adducts (predominantly 4α, 5α) and the required 6,7-adducts with both α- and #-configurations, and this mixture may be separated at this or a later stage by conventional techniques; the required6α, 7α- and 6#,7#-adducts are separated also by conventional techniques. A free hydroxy group in position 17 may be protected by acylation and subsequently released and, if desired, re-esterified. A 17-tetrahydropyranyloxy group will be hydrolysed during process (1) or (3) but it may subsequently be re-formed. Products (B) may be converted to the corresponding cyclobutano adducts (see Specification 1,176,232) by catalytic hydrogenation. The cyclobutano- and cyclobuteno-(3<SP>1</SP>,4<SP>1</SP>: 6,7)-androstane derivatives of the invention, which are variously stated to be anabolic/ androgenic, pituitary-inhibiting and progestatipnal and anti-estrogenic agents, may be made up into pharmaceutical compositions with suitable carriers.

Patent GB-619878-A (GB)
Title: Improvements in or relating to communicatioin systems and to signal receivers therefor
IPC: H04Q1/446
Filed: 1946-06-20
Abstract: 619,878. Automatic exchange systems. FLOWERS, T. H. June 20, 1946, No. 18576. [Class 40 (iv)] [Also in Group XL (c)] A signal receiver responds only to voice frequency signals i  a guard circuit protecting against signal imitation. In Fig. 1, a diode 9 or other rectifier is normally conducting to energize the bias winding 6 of an electromechanical polarized relay. The input terminals 1, 2 feed a triode V through a transformer T1, the anode circuit of the triode including three transformers T2, T3, T4. The output of the transformer T4 is full-wave rectified at QB and after smoothing is also applied to the bias winding 6, the current through which remains constant until the potential from the rectifier QB exceeds that due to the diode 9, which then extinguishes. The transformer T3 feeds a tuned circuit C, L and a full-wave rectifier QA, the output of which is smoothed and fed to the operating winding 5 of the relay. A signal of sufficient amplitude energizes the winding 5 sufficiently to overcome the bias winding 6. Speech even when including the signal frequency does not affect the signal circuit sufficiently to overcome the bias due either to the diode 9 or the speech current, whichever is greater. The transformer T2 feeds output terminals 3, 4 to give a small or no gain. In Fig. 3, a pentode 29 is normally conducting and a relay 40 is energized due to the control grid being kept at a high potential by the output of an untuned guard circuit 30-36 or of a diode 41 or other rectifier acting in opposition. A signal of sufficient amplitude, while still affecting the guard circuit, affects even more a tuned signal circuit 23, 24 which draws current through a full-wave rectifier 25 from the control grid of the pentode 29, which therefore stops conducting and the relay 40 de-energizes. The receiver may have a number of signal circuits tuned to different frequencies. As an alternative, the guard circuit may be tuned and arranged to give an appreciable output at the signal frequencies.
