Title: Improvements in the manufacture of panels of fibre-reinforced resin
Inventor: BAKER WILLIAM ANDREW
IPC: B29C44/12
Filed: 1957-11-21
Abstract: 910,821. Non-metallic pipes. BRISTOL AEROPLANE PLASTICS Ltd. Nov. 21, 1958 [Nov. 21, 1957; March 3, 1958; March 24, 1958], Nos. 36327/57, 6743/58 and 9434/58. Class 99(2). [Also in Groups V and XXXIII] A hollow cylindrical body such as a pipe is made by winding core material 101 which has been covered with a wrapping of impregnatable fibrous material 102 around a mandrel 140. The mandrel 140 is then enclosed in a tightly fitting mould, not shown, and a thermosetting resin, e.g. epoxy resin, is admitted to impregnate the wrapping and then solidified. Before winding the wrapped core material on the mandrel, the surface of the latter may be covered by one or more layers of impregnatable fibrous material, and one or more further layers may be applied over the winding of wrapped core material before this is enclosed in the mould. The core material must be sufficiently flexible to be wound in the manner described, or else be made sufficiently flexible by heating it to a sintable temperature. Specification 828,453 is referred to.

Title: Fluid regulator for breathing apparatus
IPC: B63C11/22
Filed: 1959-10-27
Abstract: 882,304. Respiratory apparatus. CHRISTENSEN, K. Oct. 27, 1959 [Oct. 29, 1958], No. 36344/59. Class 81 (2). [Also in Group XXIX] A two-stage pressure regulator suitable for breathing-apparatus for divers &c. and contained in a cylindrical housing 22 having an inlet fitting 67 with a stirrup 32 and screw 33 for attachment to a compressed-air tank, an outlet 29 leading to the face mask, and an inlet 29a communicating through a check valve 128 and openings 48 with the ambient medium, has the second stage valve 52 actuated, through toggle linkage 85, 86 and a lever 92 pivoted at 93, by a diaphragm 41 subject on one side to the ambient pressure and on the other side to the regulated pressure. A bifurcated member 80, when moved to the right by the diaphragm in response to demand, deflects the mid-point of the toggle linkage to cause clockwise movement of the lever 92 to open the valve 52. The latter, together with a bracket 89 which carries the pivot 93 for the lever 92 and the lower attachment point 87 for the toggle linkage, is carried by a plunger 50 that operates a pair of primary valves 77 to maintain the pressure in a space within the plunger at a value determined by a loading spring 62. When the supply tank becomes exhausted to the extent that insufficient pressure is available to compress the spring 62 an abutment 126 coacting with a projection 47 carried by the diaphragm impedes the latter so that the supply to the user is cut off to provide warning. The user can then move the centre part of the diaphragm laterally by means of a finger grip (not shown) connected to a lever 101 through which a stem 46 passes so as to disengage the projection 47 from the abutment 126 to allow the resumption of the supply. The finger piece can also be tilted to press the diaphragm to the right to hold the valve 52 open when desired. The check valve 128 consists of a rubber &c. disc secured at its centre 129 to a member 130 with legs 131 that frictionally engage the bore of the inlet 29a. In a modification an intermediate lever is interposed between the lever 92 and the valve 52 and in another modification an additional valve in the upper end of the plunger 50, opened by a fixed abutment, relieves excessive pressure within the plunger.

Classes 38 (2) and 38 (4)' The inductors used in conjunction with an electric discharge tube 1 comprise two inductors 4, 5 arranged in series with a capacitor 6 and the filaments 2, 3 of the discharge tube. The inductor 4 comprises a winding 11 wound on a first portion 10 of the core which forms a closed iron circuit for the flux of the winding 11 whilst the inductor 5 comprises a winding 13 arranged on a portion 12 of the core which presents air gaps 15 in the magnetic circuit to the flux from the winding 13, the fluxes in the common portion 14 of the core being in opposition when the windings 11, 12 are fed from a common alternating current supply. When starting the discharge tube 1 the inductors 4, 5 resonate with the capacitor 6 to produce a voltage greater than the supply between filaments 2, 3 to initiate the discharge in the tube. When started the discharge shunts the inductor 4, the circuit 4, 5, 6 then no longer being resonant.

Abstract: 853,534. Electric selective signalling systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 21, 1958 [Nov. 21, 1957], No. 37562/58. Class 40 (1).  In a selective signalling system in which a number of field stations S1 S2 ... S5, Fig. 1, are connected to a central station over a single communication channel each field station when it receives any data from some external source temporarily stores the data in a memory M1, M2 ... M5, until the communication channel is not in use by any other field station, and then transmits its data to the central station. In order to prevent several field stations transmitting data simultaneously the following arrangement is employed. Immediately a field station has data it wants to transmit it " listens " to the communication channel. If the channel is disengaged (i.e. if no signals are present on it) then the field station transmits a "seize " signal which comprises an A.C. signal of a frequency f1 and a duration SE1, SE2 ... SE5, Fig. 2, corresponding to the particular field station. The field station then " listens " to the channel again for a short period I, Fig. 2, and if the channel is still disengaged it transmits a " lock " signal SV also of frequency f1 and of a duration which is longer than any " seize " signal, after which it immediately transmits its data Sc. If, when a field station " listens " in an interval I after having transmitted its " seize " signal and finds the channel engaged (by another field station's " seize " or " lock " signal), then it reverts to its normal condition and continues " listening." When the channel next becomes disengaged it will make a further attempt and retransmit its " seize " signal. An outline construction of a field station (Fig. 3, not shown), is given which includes a rectifying arrangement as a " listener," transistor flip-flops and diode gates as a control circuit which ensure that the field. station only tries to transmit when it has data in its memory, and a counter, counting 25c/s pulses for controlling the production of the " seize " and " lock " signals.
