Patent GB-2030732-A (GB)
Title: Controlling Transported Material
IPC: G05D7/06
Filed: 1978-09-22
Abstract: The output of a material storage bunker (2) onto a conveyor (1) is controlled in response to the quantity of material on the conveyor (1) so that large fluctuations in material and for blockages on the conveyor are avoided. Material on the conveyor is sensed by weighing sensors (4, 5) and the sensed signal processed electrically for controlling the bunker outfeed so as to keep the flow at (4) constant. In an alternate arrangement sensor (4) is associated with the bunker output and is compared with a reference derived from a comparison of the output of sensor (5) with a reference corresponding to total flow. In both cases the error signals are integrated. <IMAGE>

Title: Picture signal coding apparatus
IPC: H04N7/26
Filed: 1978-11-20
Abstract: A gray-scaled picture is divided in a TV camera into blocks each block being composed of a number of elements. The picture signal is stored in a memory 13 and is read from the memory by a coding apparatus 14. In the coding apparatus the picture information stored is processed to provide, for a block, grey scale values a0, a1, typical of the block, as well as a threshold value xt used to determine, for each block, which of the two values a0, a1, should be applied to it for coding. Each block is thus coded by transmitting the values a0, a1, and, for each element, a parameter  phi i determining on which side of the threshold xt the element lies. The converted codes are stored in a buffer memory 15 from which they can be read out at a constant speed and supplied to a transmission line through a modem. <IMAGE>

Title: Article and Method for Conditioning Fabrics
IPC: D06M23/02
Filed: 1979-01-25
Abstract: There is provided an article for conditioning fabrics in a clothes dryer, consisting of a flexible substrate 12 carrying a conditioning agent 14 other than a soap. The substrate 12 is air- permeable and only a part of its surface or surfaces carries the agent 14, so that if it lodges against the air outlet of the dryer, at least a major part of the airflow through the dryer is still possible, and so the dryer is protected from possibly burning out due to a blocked air outlet. Preferably the substrate 12 is non-woven, and the agent 14 is printed on it in a pattern such as strips or dots. The substrate 12 may be, for example, wet strength paper and the agent 14 a softening and/or anti-static agent. <IMAGE>

Patent GB-2028953-A (GB)
Title: An Internal Combustion Engine with Exhaust Braking
IPC: F02D13/04
Filed: 1979-07-24
Abstract: An internal combustion engine comprising a spring-loaded engine valve (13) actuatable by means of a cam (2), a tappet (4) and a push rod (10), the cam (2) having a pre-lift ramp (5) for effecting exhaust braking of the engine. A single piston (6) is slidable in the tappet (4) between a bottom stop (8) and a top stop (7) therein and biased by a spring (9) against the top stop (7) and/or the push rod (10). The tappet (4) has an inlet (14) for hydraulic, control fluid to bias the piston (6) towards the top stop (7). There is also a valve (17) preventing escape of hydraulic fluid from the tappet (4) during exhaust braking. During normal operation of the engine when the pre-lift ramp (5) lifts the tappet (4) the valve (17) is held open and hydraulic control fluid flows from the tappet (4) so that the piston (6) contacts the bottom stop (8) and the engine valve (13) remains closed, whereas during exhaust braking of the engine when the pre-lift ramp (5) lifts the tappet (4) the valve (17) is closed and hydraulic control fluid cannot flow from the tappet (4) so that the pistons (6) remains against the stop (7) and the engine valve (13) opened to effect exhaust braking. <IMAGE>
