Title: Improvements in or relating to power-plants for aircraft
IPC: B64D27/06
Filed: 1943-01-12
Abstract: 564,061. Engine power plant. BRISTOL AEROPLANE CO., Ltd., and FRISE, L. G. Jan. 12, 1943, No. 589. [Class 7 (ii)] [Also in Group XXXIII] A power plant for an aircraft comprises a number of aero-engines connected to transmission shafts, disposed so that their axes intersect, radiating from a common gear assemblage each towards one of the engines, any one or combination of which is adapted to drive counter-rotating airscrews, through the common gear assemblage. As described, four pairs of radial cylinder engines are arranged within the two'wings of an aeroplane and drive four sets of counter-rotating tractor airscrews, each engine being connected to a transmission shaft bv a clutch which becomes automatically disengaged should the engine fail. Alternatively, two V-engines may be similarly arranged within fuselage or nacelle to drive counterrotating airscrews. Fig. 2 shows two engines arranged within the thickness of a wing and driving two inclined shafts 16 connected through a gear-box 17 to two counter-rotating screw shafts. Air intakes 21 are provided at the leading edge of the wing and the air after cooling the cylinders, which are surrounded by a baffle 23, issues through an opening at the trailing edge of the wing controlled by a flap 26. Air for a supercharger 25 is taken through pipes 24. Each engine is connected to its transmission shaft 16 through clutch members 30, 31, Fig. 4, the member 31 being helically splined to the engine shaft so that the drive tends to keep the teeth of the clutch in engagement, but overrunning of the transmission shaft tends to disengage the teeth. The member 31 also forms a piston in a cylinder 38 supplied with oil from the engine lubricating system so that the clutch cannot be disengaged while the engine is running. When the clutch is disengaged, the internal teeth on the member 30 are engaged by pawls 37 on the member 31 so that upon restarting an engine the main teeth are not engaged until the drive has been taken up by the pawls at synchronous speed, the time lag in the building up of the oil pressure permitting this action to take place. The two shafts 16 drive through inter-engaged toothed members 41, 42, Fig. 5, two stub-shafts 44 having bevel pinions 47, 48 in mesh respectively with an externally toothed bevel wheel 49 on a propeller shaft 18a and with an internally toothed bevel wheel 50 on a propeller shaft 18b. The shaft 18b is supported at the forward end of a casing 52 and in a partition 56. The stubshafts 44 are supported in bearings 45, 46 respectively in a diaphragm 55, clamped between the casing 52 and a casing 51, and in the rear end of the casing 51.

Title: Satellite data transmission systems
IPC: H04B7/005
Filed: 1975-01-08
Abstract: 1494124 Multiplex transmission systems SIEMENS AG 8 January 1975 [21 Jan 1974] 731/75 Heading H4M In a satellite data transmission system incorporating ground radio stations and a satellite repeater for the frequency multiplex transmission of a plurality of data channels, distortion due to the phase/frequency characteristic of the repeater (which causes differing frequency bands to be differentially delayed) is compensated in the ground stations by opposing pre-distortion in the transmitter and/or subsequent correction in the receiver. Each station is arranged and operated so that individual data channels passing through the distortion corrector(s) have the same frequencies relative to one another as they have in the satellite relay station and each distortion corrector is operable over the entire bandwidth of the band wherein the individual channels have the said same frequencies relative to one another. This differs from prior art in which each channel is separately compensated before being assembled in the multiplex group to be transmitted, so that different compensation for each channel was needed. In one embodiment (Fig. 3) the separate channels to be transmitted from a ground station (e.g. six) each frequency modulate the same carrier f m , these carriers are then converted by individual local oscillator frequencies to produce a range of contiguous frequency bands F z1 -F z6  which are multiplexed at K1. The multiplex group is passed to distortion correcting device E which corrects over the entire transmission band. The corrected signal is then converted at R to the appropriate transmission frequency, passed to a further coupler for a number of transmission bands and thence to power amplifier V and antenna A. In a different embodiment (Fig. 5), each channel signal f m  is transferred to its relevant frequency band F z1 -F z6  and each of these bands is passed through an identical corrector E1-E6; each corrected signal is thereafter corrected to the transmission frequency by mixing with the same local oscillator signal GR. In a third embodiment (Fig. 6, not shown) the different channels are converted to the transmission frequency before multiplexing and the multiplexed signal is applied to the correction device.

Title: Electrical Connector.
IPC: H01R12/72
Filed: 1969-01-06
Abstract: 1,182,913. Two-part couplings. AMP Inc. 6 Jan., 1969 [29 Jan., 1968], No. 768/69. Heading H2E. An electrical edge-connector comprises a channel-shaped insulating housing containing a plurality of contact elements, each of which has portions extending through respective openings in the housing side walls and engaging the side wall, so that the side walls are supported by the contact elements and the contact elements are located in the housing by the side walls. In a preferred embodiment, (Figs. 1, 2), each element comprises two contact arms 8 formed integrally with lugs 10 and oppositely bowed contact flanges 12 which extend in a direction normal to the plane of the base part 6. The lugs 10 engage the housing 4 at portions 37 adjacent key-hole slots 36 in a manner sequentially illustrated in Fig. 1. A detent 18, engaging the base of the housing, prevents withdrawal of the element, and flanges 14 support and locate it when in position on a printed circuit board 42, (Fig. 2). The U-shaped post 20 extends through the base of the housing, and may be soldered to printed circuit contacts 46. The housing may be of a resilient plastics material, which may be hot or cold formable, e.g. polyvinyl chloride or dichloride, or a non- polymeric material such as insulating paper. Manufacture of the housing may be by shaping in outline a strip of plastics material, punching out the slots in the base and side walls, and bending to channel-shape, after which contact elements may be inserted mechanically (Fig. 4, not shown). Alternatively, the housing may be produced by extrusion followed by a punching operation. In a modification (Figs. 5, 5A, not shown), the contact is substantially uniplanar, and has a slot in the end of each contact arm to engage a vertically extending portion of the housing. A boss (72) replaces the retaining detent 18. In a further embodiment (Figs. 6, 7, not shown), the contact element comprises a pair of tubular portions (96, 98) connected by straps (100), upstanding ears (103) engaging a portion of the housing extending parallel to the base. Contact springs (102) extend inwardly between the tubular portions (96, 98). The locking boss (101) may be replaced by a resilient detent (110) engaging a further opening in the side wall (Fig. 8, not shown). In a further embodiment, the insulating housing has a wider base (Fig. 9, not shown), so that contact tabs may be inserted from the side of the housing. Ears (138) engage the housing walls, which are sufficiently spaced for the contact to be inserted through them. In a further embodiment (Figs. 11, 12, not shown), the connector comprises two leaf spring contact members (150), from each of which is struck an upstanding ear (160) to engage the housing. The contact members are joined by an insulating yoke (164) which carries a retaining boss (165).
