Title: Broadband rotating beam antenna system
IPC: H01Q3/14
Filed: 1975-03-17
Abstract: 1506201 Rotating beam aerials E-SYSTEMS Inc 17 March 1975 [3 June 1974]11014/75 Heading H4A An antenna system, comprising in combination a central elongate radiating member 10 arranged to transmit energy from a feed point, a first plurality of parasitic elements 28, 28a radially displaced from said central member, a support of nonradiating material 56 having a top and bottom surface oriented generally perpendicularly to the longitudinal axis of said central member, a second plurality of parasitic elements 58-66 each element having a first section disposed to extend over the support top surface, a second section disposed to extend over the support bottom surface and an intermediate section joining the first and second sections to form therewith a transmission line section (Fig. 4), said intermediate section being the only section of each element of said second plurality providing significant radiation, and said first plurality of parasitic elements and said support disposed for rotation about said radiating member. A basically TACAN system is made to operate over a wide spectrum (about 900-1200 MHz) by the use of groups 58 of outer parasitic elements 68, 70 having a U-shape disposed on a dielectric disc 56, the effective length y of the legs keeping the modulation depth approximately constant over the operational frequency range. The frequency response of each element 68 depends on its electrical parameters. The elements pertaining to a particular frequency band are arranged at a given radius in nine groups 58-66. The U-shaped elements may be paired as in Fig. 2 or may be single and the legs may be radial (Fig. 11, not shown) or circumferential, but opposed pairs 68, 70 improve the polarisation purity of the radiation. In the embodiment shown in Fig. 8 vertical beam directivity is obtained by stacking two TACAN systems 138, 144 between conductive surfaces 112, 114 and 116, 118 so that the separation of the systems 138, 144 is #/2 of the excitation frequency of the central member 124. This structure radiates a well-defined beam radially outwards parallel to the conductive surfaces when the aerial systems 138, 144 are fed in phase. In a further embodiment (Fig.10, not shown) a counterpoise plate (170) is incorporated. The use of two pairs of U-shaped elements in each group 58-66 allows the aerial system to operate at two separated relatively narrow bands within the 900-1200 MHz range. The orientation of the U-shaped elements may be other than radial or circumferential.

Abstract: 672,440. Storing gases under pressure. TENNANTS CONSOLIDATED, Ltd. May 4, 1950 [May 6, 1949], No. 11074/50. Class 8 (ii) Chlorine dioxide is stored e.g. for transportation by dissolving it in liquid chlorine and maintaining the mixture in a closed vessel at such a temperature and pressure that vaporization of chlorine from the mixture does not increase the content of chlorine dioxide above one-third of the weight of the liquid mixture. The chlorine dioxide gas which is generated in known manner and diluted with air is passed through liquid chlorine at -30‹ to form a completely miscible solution of the above concentration. Such a solution is stable when subjected to underliquid sparking below -39‹ C. At increasing temperatures the safe proportion of chlorine dioxide falls to 27 per cent which is stable up to 40‹ C.
Patent GB-560095-A (GB)
Title: Improvements relating to the manufacture of materials comprising mineral wool
IPC: C03C25/323
Filed: 1942-08-07
Abstract: Sheets, slabs, blocks, pipe and other sections are made from mineral wool, slag wool, glass wool, or rock wool by a process involving mixing an aqueous suspension of mineral wool fibres with an aqueous emulsion comprising an alkyd resin or an oil-modified phenol-formaldehyde resin, and precipitating the resin on the wool fibres by the addition of an acid or acid salt such as alum, zinc sulphate, or phosphoric acid.  The alkyd resin may be modified with Tung oil or other drying oil having three conjugated double bonds, or may be chemically reacted with a drying oil and a reactive phenol-formaldehyde condensation product.  The oil-modified phenol-formaldehyde resin may also be prepared with the aid of Tung oil.  The resin may be emulsified in the molten state, or as a solution in benzene, toluene, or white spirits, with the aid of ammonium caseinate, methyl cellulose, 1-iso-propyl-naphthalene-4-sulphonic acid, or other emulsifying agent.  The mineral wool fibres may be pretreated with water-repelling, non-volatile, petroleum products or with starch, which may be added at the time of forming the fibres e.g. by injecting starch paste into the fibre-forming steam jets. Alternatively a starch paste may be added to the mineral wool suspension before or after the resin emulsion.  Bentonite may also be added to the fibre suspension or the resin emulsion.  The pH value of the resin emulsion is adjusted with ammonia solution to equal that of the fibre suspension.  After precipitation of the resin on the fibres, the mixture may be run into moulds, excess water drained off, and the mould pressed and/or heated.ALSO:Sheets, slabs, blocks, pipe and other sections are made from mineral wool, slag wool, glass wool, or rock wool by a process involving mixing an aqueous suspension of mineral wool fibres with an aqueous emulsion comprising an alkyd resin or an oil-modified phenol-formaldehyde resin, and precipitating the resin on the wool smoothing segments 31 the outward traverse of which is limited by fixed skirts 271 depending from the disc.  The disc 27 and the mould 10 are rotated, by independent means, in the same direction, the disc faster than the mould.  The disc is raised by hydraulic means, as moulding proceeds.  The moulded body may be produced in layers of the same or different materials, e.g. cement and as asphalt.

Title: Return prevention device, particularly for hydraulic or pneumatic motors
Inventor: HANS KURT
IPC: F16D41/08
Filed: 1962-03-22
Abstract: 951,010. Self-sustaining gear. INSTITUT FUR FORDERTECHNIK LEIPZIG. March 22, 1962, No. 11105/62. Heading B8B. [Also in Division F2] In a return prevention device (see Division F2) for hydraulic or pneumatic motors used in driving cable winches, one or more braking cams 6 are disposed in an annular body or ring 4 extending around a rotary member 2 which is to be prevented from returning, an operating piston 12 is associated with each braking cam to unlock the latter and is connected through a conduit 13, 15 to a piston slide valve 23 through which hydraulic or pneumatic pressure can be applied to the pistons 12. In operation, a spring 8 (Fig. 2) presses a pressure member 10 lightly against each braking cam 6 so that the latter bears on the peripheral surface of the rotary member 2 at the point of contact 9. If the rotary member 2 is turned in the direction of the arrow a the cams 6 slide over the periphery of the rotary member 2 without any appreciable resistance. With an oppositely acting torque the rotary member 2 is turned in the direction of the arrow b and the cams 6 are clamped between the point of contact 9 and the tilting shaft 5 and thus lock the rotary member 2 to the ring 4. To release the brake cam 6 from the rotary member 2, for example in order to drive a cable winch in the lowering direction, the cams 6 are pressed by the pistons 12 and thereby released from the rotary member 2. In the construction shown in Fig. 4 the braking cams 6 may be applied and released automatically. An automatic control valve assembly 19 is connected to conduits 16 and 17 forming the main supply and discharge conduits for the pressure medium to the hydraulic motor with the oblique faced disc 2 through the two conduits 20 and 21. If the hydraulic motor is supplied with pressure fluid through the conduit 16 (Fig. 4), the rotary member 2 turns in the direction of the arrow a (in the direction of lifting), the braking cams 6 being lightly pressed by the springs and sliding on the rotary member 2. When the motor has stopped the braking cams 6 prevent its return for example, by reason of a raised load supported by a winch connected to the motor. The return torque is transferred to the cams 6 to the extent to which the fluid column is slackened by the leakage or gap losses in the motor. If the motor is to run in the direction of the arrow b (to lower the load), the pressure fluid is supplied through the conduit 17. This fluid pressure produces an additional torque in the engine in the direction of the arrow b, apart from that caused by the raised load. After filling, the pressure in the conduits 17 and 21 increases and moves the piston slide valve 23 against a spring 24 to cut off the return connection 25 from the cylinder 11 and at the same time to connect the conduits 26 and 27 to the latter.

Abstract: 1,062,772. Respiratory apparatus. G. B. BURCHELL. June 22, 1964 [March 20, 1963], No. 11149/63. Headings A5T. A respiratory apparatus for supplying gas to a patient through a conduit 19, 51 and withdrawing gas from the patient through a conduit 21, 53, 51 comprises a bellows 1 moved by a pneumatically driven piston 2 and a conduit 29 leading from the bellows to a control 30 opening to atmosphere 31, the conduit having a valve 27 which is opened for an adjustable time interval when the pressure in the patient's lungs is at its maximum whereby the patient's lungs may quickly exhale to atmosphere for a certain period via the conduit 21, 53, 51, the bellows and the conduit 29, 31. As shown, the bellows 1 is controlled by valves 12, 16 triggered by the moving bellows wall 26, and the valve 27 is opened by an abutment 25 when the wall is at the limit of its pressure stroke, the period of time for which this valve is open being governed by the rise of the wall 26 in turn dependant on the setting of a throttle 15. The apparatus also includes a carbon dioxide absorber 23, a bag 24 and valve 18 allowing manual operation, a reservoir bag 35 with maximum and minimum relief valves 37, 36 and in the exhalation and inhalation conduits 21, 19 relief valves 38, 39. Dependant upon the position of the valve 30, the conduit 29 is open to atmosphere 31 or, for closed circuit operation, to a conduit 32 supplied from a conduit 33 with anaesthetic gas, air, or a mixture of these. The apparatus may be provided (Figs. 6 and 8, not shown) with a device whereby a slight inhalation by the patient causes the bellows to perform an inhalation stroke. The modified apparatus of Figure 8 (not shown) includes two bellows, one (200) performing the exhaust stroke from the lungs and the other (201) providing inhalation gas. The position of the valve 12 (112) in each form of apparatus is adjustable to regulate the volume of the respiratory flow.
