Title: Improvements in and relating to radiators for the engines of aircraft or other vehicles
IPC: B64D33/10
Filed: 1937-12-14
Abstract: 493,673. Ducted radiator for aircraft. JUNKERS FLUGZEUG - UND - MOTORENWERKE AKT.-GES. Dec. 14, 1937, No. 34583. Convention date, Dec. 22,1936. [Class 4] An annular radiator for an aero engine is disposed around the cowling of the engine to be cooled, which cowling is approximately a solid of revolution and tapers uniformly toward the front, and is surrounded by a shell which with the cowling defines an annular air inlet opening and a convergent annular outlet such that the issuing cooling air flows smoothly along the cowling. In one form, Fig. 1, a radiator 3 and an oil cooler 4 are located between engine 1 and airscrew 2. Radiator 3 is mounted either on cowling 6 or on a ring 7, as shown, braced to the fuselage by members 15, Fig. 3, casing 5 is in the form of a hollow ring of which the outer surface conforms to the streamline shape of the cowling. The inner surface 9 of the casing in conjunction with the forward constriction 10 of the cowling forms an annular nozzle 11, the area of which is adjustable by axial movement of a sleeve 14 on the cowling or, according to a modification, by axial movement of the housing itself. Alternatively, the trailing edge of the housing may comprise adjustable hinged louvres. The front boundary of housing 5 is inturned at 12, the inner front edge of the radiator is also curled at 13. Radiator 3 is divided into two sectors 16, 17, Fig. 2, secured on ring 7 with a rubber sleeve 20, Fig. 3, interposed, by clamping rings. Each sector comprises a header 22 and an outflow collector 24. The air passing through oil cooler 4 escapes from the cowling through gills 28 provided with louvres 29, Fig. 1. Cooler 4 is also divided into two sectors held in position by straps, the plane of division of the two sectors being staggered with respect to that of sectors 16, 17. Both radiator and cooler comprises curved tubes for the liquid to be cooled and radial fins 48 which are bent on the intake side in such manner that they run approximately tangentially to the direction of the movement of the airscrew slipstream. In a modification, an oil cooler and a radiator, both of sectoral shape, are mounted so as together to form an annulus.

Abstract: 1,134,762. Moulding peat. BORD NA MONA. 4 Sept., 1967 [4 Aug., 1966], No. 34935/66. Heading B5A. Moss peat, e.g. sphagnum moss peat for horticultural application, is dried in a comminuted or granular condition and is then subjected to compression in a mould to produce a cake of <SP>1</SP>/6to <SP>1</SP>/12of the bulk of the peat before compression, the peat being restored to its original bulk and fragmentary condition by subsequent wetting. The fragmented peat is preferably dried at a temperature below 65‹ C. in a drier conveyer duct such as a cyclone or gas or steam heated drier, to 10-30% by weight of moisture content. A non-ionic wetting agent, in the amount of .05 to 0.5% of the dry peat weight, and other additives may be added to the conveyed stream of dried moss prior to moulding under 1-4 tons per square inch until it is compressed to about <SP>1</SP>/14 of the original volume, from which a certain recovery occurs to the desired compression. The compressed cakes may be laid directly in stalls and fowl houses for use as litter, the peat in time resuming its fragmentary condition without creation of dust. For horticultural application, a similar weight of water is added to the cake by spraying or immersion.

Abstract: 1392818 Telephone exchanges PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 July 1972 [29 July 1971] 34941/72 Heading H4K In a transit T.D.M. exchange adapted to selectively interconnect P.C.M. highways provision is made to generate and transmit multifrequency tone codes, said tone codes being generated from stored code representations of tone combinations. In the exchange shown incoming P.C.M. highways 100-1 to 100-8 are selectively interconnected with outgoing P.C.M. highways 101-1 to 101-8. The exchange employs more time slots than the incoming highways combined and these are used to transfer stored representations of all possible multi-frequency codes to additional locations in the intermediate speech store 108 and under the control of the exchange processor to transfer selected tone codes from the store 108 to selected slots on the highways 101-1 to 101-8. The incoming highways terminate in synchronizing circuits 102-1 to 102-8 which add on separate output lines 104-1 to 104-8 the identities of the time slots and highway involved to a scanner 105. The identities are used to address the store 108 which is of the random access type having one location for each incoming channel and one location for each possible multi-frequency code combination. The latter locations are necessively accessed using addresses generated from an address store 119 and each time such a location is accessed it is fed with a P.C.M. code from a cyclic store, said codes representing successive samples of a corresponding tone combination waveform. The cyclic store may be a shift register storing codes corresponding to samples taken from a quarter waveform and fed out in forward, reverse, inverted and inverted reverse order to generate a complete wave shape. The particular storage locations of store 108 to be read out at particular times and the crosspoints 110 and 116 to be operated to route the read out P.C.M. speech and tone codes to the outgoing channels on highways 101-1 to 101-8 are controlled by cyclic stores 112, 113 and 117 updated by the common control.
