Patent GB-2068013-A (GB)
Title: Heating feed streams for hydrocarbon processing
IPC: C10G49/00
Filed: 1980-01-18
Abstract: The need to heat a mixed phase hydrocarbon feed in a fired heater is avoided by heating at least a portion of the effluent stream 6 (from which vaporous components 8 can be removed), e.g. in a fired heater 11, and using the heated product 13 as heat exchange medium for heating the mixed phase hydrocarbon feed stream 3 in the indirect heat exchanger 4. The heating process can be used in hydrocarbon processing such as the hydrodesulphurization of blackoil, the isomerization of C4-7 paraffins or C7-9 aromatics, reforming, hydrogenation of pyrolysis gasoline, visbreaking and the thermohydrodealkylation of toluene. The feed can be heated in admixture with hydrogen. <IMAGE>

Patent GB-2101705-A (GB)
Title: Energy absorbing arrestor
Inventor: DOMAGALA JOSEPH EDWARD
IPC: E01F15/04
Filed: 1981-07-15
Abstract: An energy absorber (or arrestor) working on the principle of straining an elongated element by pulling it through a tortuous path over rotatable rollers and characterised by the element (9) being of flexible laminar construction. The flexibility of this element allows it to be formed into a conveniently small coil, the diameter of which being that of an equivalent section rigid element divided by the number of laminae. The rollers (1-6), similarly reduced in diameter, are arranged into two opposed banks which temporarily divide the element into two equal and opposite laminar groups (10-11), the angular reactions of which counterbalance each other. The normally heavily loaded exit rollers (5,6) are substantially assisted by contact with remote support bearings (7,8). The end of the element is anchored by entrapping two equal groups of laminae, utilising the strain energy principle and retaining the use of the full tensile area, (Figs. 3-5, not shown). <IMAGE>

Title: Method of Cutting With a Hand- guided Cutter
IPC: B26F1/38
Filed: 1981-07-28
Abstract: A method for working on limp sheet material 12 uses a hand-guided cutter 44 and a vacuum holddown device 36, 40 having a penetrable material 30 supporting surface. A panel of substantially air-impervious material 42 is spread over the exposed surface of the sheet material lying in a generally flat condition on the penetrable supporting surface. The vacuum holddown device applies a vacuum between the air-impervious panel and the penetrable supporting surface and draws the panel toward the supporting surface. As a result, the sheet material is placed in a relatively rigid condition for cutting. The hand- guided cutter with a reciprocated cutting blade 46 is directed over the panel along a desired line of cut while the cutting blade in cutting engagement with the sheet material penetrates through the material and the supporting surface. <IMAGE>

Title: Apparatus for collecting ferrous debris in engine oil or transmission oil
Inventor: CRANE RAYMOND
IPC: F16N29/00
Filed: 1984-03-14
Abstract: A magnetic plug 12 attracts and holds ferrous debris 11 in the oil of a gearbox or engine, for example of a helicopter or land based vehicle. A reciprocable feeler member 14, driven by a double-acting piston 19 in a cylinder 20 is made to approach a surface 13 of the plug 12 as close as the debris 11 on the plug 12 will allow. Measurement - by means of a linear displacement variable transformer 23 - of how far the debris 11 holds the feeler 18 proper away from the plug surface 13 indicates the amount of ferrous debris 11 on the plug 12. In between readings, the feeler 18 proper is held away from the surface 13, which is thus exposed to the ferrous debris in the oil to collect on the surface 13. <IMAGE>
