Patent FI-863154-A (FI)
Inventor: KETTERLING HANS-PETER
IPC: H04W16/32
Filed: 1986-08-01
Abstract: A radio telephone network is proposed, the radio cells (1A) of which are subsequently divided into immediately adjoining radio microcells (1d, 2d...) with an increased traffic volume. For this purpose, at least two radio microcells (1d, 2d...) are formed within a group (FB1) of radio cells. Each radio microcell exhibits a low-power central radio station (bd1). It is essential that the radio microcells are arranged in such a manner that the greatest possible equally large distances (d) from stationary radio stations of the same frequency are obtained. <IMAGE>

Abstract: Reduction of electrode metal dissolution in electrolyte between two metal electrodes of a voltaic cell by adding an electrode metal dissolution reduction agent to the electrolyte prior to operation of the cell, the electrode metal dissolution reduction agent being a sacrificial electrode metal, a metal promoting common ion effect with one of the electrode metals, seed metal particles serving as precipitation sites for an electrode metal, and combinations thereof. Reduction of the electrode metal dissolution in the electrolyte of a voltaic cell is also achieved by maintaining a partial pressure of carbon dioxide of about 0,5 to about 1,5 atmospheres in the electrolyte during operation of the cell. The method and electrolyte is particularly suited for molten carbonate fuel cells.

Title: Improvements in or relating to ethylene chlorohydrin and ethylene glycol and method of obtaining same
IPC: C07C31/34
Filed: 1949-01-17
Abstract: Ethylene oxide is passed into aqueous hydrochloric acid until the solution is neutral, and ethylene chlorhydrin and ethylene glycol are recovered therefrom.  A gas containing ethylene oxide and obtained, e.g. by catalytic oxidation of ethylene, may be employed.  The formation of glycol may be reduced by using more concentrated hydrochloric acid, or by adding a soluble metallic chloride and increased by reacting at a higher temperature.  The ethylene chlorhydrin-water azeotrope first obtained by distillation of the product may be reacted with milk of lime to give a more concentrated ethylene oxide, which may be used again in the process if glycol is the desired product.  The product obtained from ethylene and chlorine water and which contains equivalent quantities of ethylene chlorhydrin and hydrochloric acid, may be used instead of aqueous hydrochloric acid itself. Examples of the process are given.

Abstract: 576,499. Composite fabric articles. TRUBENISED, Ltd., and BIHALY, L. Feb. 1, 1943, No. 1646. [Class 140] [Also in Group V] Shaped articles such as breast-cups for brassieres are made from fabric knitted from composite double strands consisting of separate strands lying alongside each other and knitted together simultaneously, one strand being of thermoplastic material such as cellulose acetate, and the other of non-thermoplastic material such as cotton, linen, viscose, or silk wool, the fabric so knitted being stretched out of its plane as by moulding, without the aid of heat, and set in stretched shape by treatment as with a solvent or softener to render the thermoplastic strands adhesive, followed by pressure, and heat if necessary, to fuse together in manner known per se the two kinds of strand where they cross. If the thermoplastic strand contains a plasticizer, the softener may be an agent, e.g., alcohol, acting on the plasticizer. The material may be shaped and set as a single layer; or it may form one layer of a two-ply material or the middle layer of a threeply material, the remaining layer or layers consisting of knitted or loosely-woven cotton, linen, viscose or like fabric capable of being stretched to the same degree as the layer of composite material; or two layers of the composite material may be joined together by fusion to form a twoply material. Fig. 2 shows in stretched condition a fabric knitted with double strands of which A is cellulose acetate and C is cotton, the crossings B' of the two lower rows being shown in their set condition after fusion. Moulding apparatus is described (see Group V) for shaping cups for brassieres; and a brassiere is described, built up as described in Specification 576,522, [Group VII], from cups so shaped from the aforesaid material.

Title: Improvements in wave guides
IPC: H01Q19/13
Filed: 1945-01-22
Abstract: 590,351. Wave guides. WESTERN ELECTRIC CO., Inc. Jan. 22, 1945, No. 1757. Convention date, Jan. 25, 1944. [Class 40 (v)] A change in direction of a wave guide is carried out by a. pair of bends so differently orientated that the elliptical, polarization of originally plane-polarized waves caused whilst they traverse the initial bend is converted back to plane polarization by traversing the second bend. Spacing of the bends may be adjusted so that the partial reflection occurring in one bend is compensated by that occurring in the other. In Fig. 1, the circular wave guide has two similar right-angle bends 10, 13 lying in mutually perpendicular planes. A planepolarized wave entering the guide section 11. at any angle of polarization emerges from guide section 14 with substantially no elliptical polarization, since the phase change introduced by bend 13 is substantially equal and opposite to the phase. change introduced by the bend 11. This arrangement is effective to suppress elliptical polarization over a wide range of frequencies. If the spacing L between the bends is a half wavelength within the guide or is a multiple thereof, the waves reflected in one bend are in phase-opposing relation to those of the other bend and so reflection is reduced to a minimum. The arcuate length of the bends 10, 13 should also be a half wavelength, in order to produce minimum reflection. In Fig. 4, the guide section 11 is vertically disposed above a fixed guide section 22 and is mounted to rotate about its axis. As the section 11 rotates, the planepolarized waves effectively enter it at a continuously varying angle of polarization. The angle of the plane-polarized waves emerging from the section 14, whose end is placed at the focal point of a paraboloidal reflector 20, is therefore continually varying about a horizontal axis.

[Class 4] A small parachute or a weight attached to a cable allowed to pay out from an aircraft in flight or relative movement between a glider and its towing cable, is utilized to store energy in a hydraulic or spring system for subsequent use in operating wing flaps, radiator shutters, bomb-doors, variable pitch airscrews, &c., or for the direct retraction of an undercarriage. Fig. 2 shows a cable, connected to a small parachute (not shown), trailed behind the aircraft and the pull utilized. to turn a drum 7 to actuate through gearing 8 a pump 9 for working a jack 14. A clutch 18 enables the drum to be coupled alternatively to the gearing 2 or to a worm-wheel 21 which can be turned by a worm and hand wheel 22 to wind in the cable after use. A separate cable may be attached to the apex of the parachute to enable it to be reversed before it is hauled in. Fig. 3 shows a towed glider having an undercarriage leg 25 pivoted at 26 and connected at its upper end to the towing cable 61. A down lock 27 holds the leg in its operative position, but when the lock is released the cable raises the leg and simultaneously compresses a spring in a cylinder 29 for use when it is desired to extend the leg. An up lock 28 automatically engages the leg as it is raised.
