Patent GB-301429-A (GB)
IPC: C08G63/127
Abstract: 301,429. Herz, E. von. Nov. 29, 1927, [Convention date]. Artificial resins may be obtained by condensing pentaerythrite, or the water soluble condensation product obtained as a by-product in the manufacture of pentaerythrite, by condensing acetaldehyde and formaldehyde in the presence of an alkaline earth, such as calcium hydroxide, and water, with phthalic acid or anhydride. According to an example, the two components are heated together at a temperature of 140‹ C., continually reintroducing the sublimed phthalic anhydride, until sublimation ceases. The resin thus obtained is soluble in alcohol and acetone. On heating at 180‹ C. until the evolution of water vapour ceases, the resulting body possesses a higher melting point and is only soluble in acetone, while on heating still further or still higher, it is transformed into an infusible and insoluble substance. According to the duration of the condensing and hardening process, the products isolated at various stages differ in solubility, fusibility and stability. They may be used for lacquers, polishes, varnishes, adhesives, mouldings &c., and as an insulating material for electrical purposes. Specification 289,794 is referred to.

Title: Improvements in or relating to wireless receivers
Inventor: MORTLOCK ALFRED
IPC: H03G3/22
Filed: 1948-11-19
Abstract: 654,506. Automatic gain control. STANDARD TELEPHONES & CABLES, Ltd. Nov. 19, 1948, No. 30143. [Class 40 (v)] In a circuit providing a delayed automatic gain control voltage, the delay bias is completely removed as soon as the signal exceeds the threshold value. Signals are applied to terminals 15, 16 to which a rectifier 19 is connected in shunt. A valve 1 connected in series with resistances 6, 7, 8 across the supply 3, 5 is biassed from resistance 8 so as to be conductive in the absence of signals. The current through the resistances provides a bias for the rectifier 19, at the adjustable tap 9 which renders it conductive, so that it forms a shortcircuit across the input. When signals exceed the threshold value determined by the bias, peaks are passed over condenser 21 to a rectifier 22 and produce a negative-going potential which is applied over a smoothing circuit 13, 14 to the grid of the valve 1. The resulting fall of anode current reduces the bias on the rectifier 19 and results in a bigger signal being applied to the rectifier 22 ; the action is cumulative, so that valve 1 is rapidly cut-off and the delay bias on the rectifier 19 removed. As shown, the arrangement functions as an electronic switch, and in order to utilize it to obtain delayed A.G.C. the earth is removed to the point 25, the output being taken from the point 26.

A parachute has a substantially triangular canopy 11, consisting of a number of strips 18- 24 arranged across the canopy, the strips 22-24 providing wings 59, 60. Rigging lines are attached to the risers 14, 15, 16, 17 of a parachute harness. The canopy flies with strip 18 forward and the front edge folded back to form a pocket (Fig. 5, not shown), the strips 18-20 are joined over the whole of their lengths, but strips .21-24 are joined to their adjacent strip for a part only of their length so as to leave apertures between the strips, the leading edges of the apertures being formed by folding back the material of some of these strips (Fig. 6, not shown). The strips 21-24 are provided with control vanes, such as 44-55, which are connected by control rigging (48, 49), (Fig. 3, not shown) to the risers 14, 16, and are used to control the aperture size and shape, and hence the parachute in flight. The canopy is provided with a keel consisting of a number of triangular vanes 25-30 attached to the strips 19-24 and the bell lines 31-37 are attached to the harness. In another embodiment the keel vanes are also attached to the canopy strips, Fig. 10, the strips 21-24 overlap, the material not being folded back (Fig. 12, not shown) and no control vanes are provided. The canopy is steered by control lines from the corners 66-69 of the wings 59, 60; a continuous line 78, 79 passes through a ring (80), (Fig. 13, not shown), on the harness, shortening line 78 by means of the lines (83), (82), (Fig. 13, not shown), lengthens 79 and causes turning. Operation of both wings at once causes the canopy to brake.

Title: Apparatus for controlling the production of inert atmospheres
IPC: C21D1/76
Filed: 1938-10-22
Abstract: 520,450. Controlling inert atmospheres in furnaces. BRITISH INSULATED CABLES, Ltd., BANNISTER, L. C., and CLEMENTS, W. J. Oct. 22, 1938, No. 30595. [Class 51 (ii)] [Also in Group XXIX] Apparatus for controlling an inert atmosphere for furnaces produced by .burning combustible gas and oxygen comprises a mixing valve for proportioning the supply of gas and oxygen, an instrument for continuously determining the calorific value of the gas supplied to the mixing valve and a device which automatically adjusts the setting of the valve in accordance with the calorific value of the gas to maintain the inertness of the combustion products. The mixing valve 1 is of the kind described in Specification 491,408, [Group XXIX], and the rotation of the sleeve 6 to vary the relative size of the gas and air ports 3, 4 is effected by an electric motor M coupled to the sleeve 6 through gearing G. The calorimeter 11 comprises steel tubes 13, 14 connected at their lower ends and heated by a gas jet 12 supplied by the gas mains leading to the mixing valve. Differential expansion of the tubes 13, 14 operates through gearing an electric contact C which according to the calorific value of the gas engages contact C1 or C2 and through electric circuits controls the direction of rotation of the motor M to vary the relative sizes of the gas and air ports of the mixing valve. When the contact C engages contact C1, relay U operates to close contacts U1 ... U4 and operate a delay relay D and relay MU which closes its contacts to start the motor M in a direction to adjust the relative sizes of the gas and air ports of the mixing valve. After the predetermined delay of relay D has elapsed its contact D1 is closed to operate relay UA the contacts of which are actuated to release relay MU and complete the circuit to relay ML which reverses the motor connections momentarily. Operation of relay UA causes one of its contacts to release relay U, which is designed to be slow to release, and when such release takes place relay ML breaks the motor circuit. The motor M is similarly actuated in the reverse direction when the contact C engages contact C2 by relays L, LA, ML. The connecting link between the calorimeter and mixing valve may be mechanical or partly electrical and partly mechanical.
