Title: Communication system with reduced fading sensitivity
IPC: H04B7/04
Filed: 1969-10-09
Abstract: 1,272,975. Digital transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 9 Oct., 1969 [15 Jan., 1969], No. 49661/69. Headings H4L and H4P. The effects of frequency selective fading on a frequency division multiplex signal are reduced by subjecting the signal to a Fourier transform, the resultant signal being transmitted. The transformation has the effect that a long face at a particular frequency appears at the receiver as a short fade over a number of the channels, this short loss of signal being correctable by known techniques. In the embodiment described, Fig. 2 (not shown), binary data from four sources passes to units which add error-correcting redundancy. The signals are now 4-phase modulated on four separate frequencies, and the modulator outputs summed to give the f.d.m. signal. The f.d.m. signal is sampled and the samples converted to multi-level form. Alternative multi-level samples are fed to respective first and second pairs of shift registers which supply the samples in the correct and the reversed order to a Fourier transform unit. The output of this unit is converted to analogue form and transmitted over a radio channel. At the receiver the inverse process takes place.

IPC: B08B9/34
Filed: 1966-11-11
Abstract: 1,209,305. Cleaning containers. THOMAS HILL ENG. CO. (HULL) Ltd. 9 Nov., 1967 [11 Nov., 1966], No. 50627/66. Heading B8T. A container cleaning machine comprises a plurality of interconnected cleaning heads each mounted on a rod 36 whose vertical movement is controlled by a spring (not shown) and a cam track 42 which abuts against a cam roller 40 carried by a stub shaft at the inner end of the rod 36. The cleaning heads 16 are rotated on an endless chain conveyer 10 formed of two series of links 28 running on chain wheels 12, and are fed by a cleaning fluid distributer, containers 20 being delivered to seats 18 of the cleaning heads by a star wheel 24 fed by a conventional conveyer (22), Fig. 1a (not shown). In the container delivery position the cleaning head 16 is elevated by the cam track 42 and the container is freely received on to the seat 18. As the rotation of the head continues the roller 40 leaves the cam track 42 and the container is clamped between seat 18  and cleaning head 16 under the action of the spring until the initial upright position is regained. With compressed air as cleaning fluid, a clamp cup 38 of each cleaning head 16 supports an air cylinder 44, within which a piston (46), Fig. 2 (not shown), carries an air jet tube (50). At the lowest point of the cleaning cycle a burst of compressed air from the distributer via a flexible tube 48 acts on the piston (46), projecting the tube (50) into a bottle 20, and enters the bottle through tube (50), while a supporting spring (49) withdraws the tube (50) from the bottle 20 at the end of the air burst. An inlet to a dust extractor (52), Fig. 1a (not shown), is traversed by the cleaning head 16 as the air is expelled from the bottle 20. The fluid distributer comprises a cylindrical rotor 58 in a fixed housing 54. Compressed air enters through the hollow interior of the rotor 58, reaching an outer helical groove 60 through one or more radial ports 62. Radially parallel ports 64 lead to the upper flat surface 55 of the housing 54, and as the rotor shaft 58 turns compressed air emerges from the succession of ports 64 as a travelling air stream. The rate of travel parallel to the rotor axis is governed by the rotor speed, and is adjusted to correspond with that of each air pick-up shoe 66 rotating with the cleaning head 16 and connected to the corresponding flexible tube 48. An air-tight joint between the housing 54 and the shoe 66 is ensured by resiliently biased rollers 76, and several pick-up shoes 66 may operate simultaneously.
