Title: Strip or wire accumulator
Inventor: LANGLEY JAMES ARTHUR
IPC: B65H23/04
Filed: 1983-07-20
Abstract: A strip or wire accumulator includes a plurality of rotatable rollers (18-22) spaced from one another and with parallel axes of rotation, and a loop-forming strip or wire guide element (52-56) between and slightly below each adjacent pair of rollers. A loop chamber (12-16) extends substantially vertically downwardly beneath each guide element (52-56). The arrangement is such that the strip in the accumulator hangs freely in loops, one loop being in each loop chamber. Each chamber may be 10 metres in height. The accumulator is used to supply strip continuously to a downstream production unit whilst the feed coils (30) are changed. The loop sensors (5) are used to control the drives to rollers (18-22) and operate when the respective loop chambers are full. The stop switch (SW) in the entry chamber stops the downstream production unit when the accumulator is nearly exhausted. <IMAGE>

Title: Optical sight
Inventor: NEWTON ROBERT KELVIN
IPC: G02B27/32
Filed: 1984-01-24
Abstract: An optical device, primarily for use as an optical sight, comprising a parallel sided, flat plate (10, 30) a transparent material such as optically pure Perspex (Registered Trade Mark), the plate (10, 30) having a circular through hole (12, 32) whose axis is perpendicular to the side faces of the plate. When the hole (12) is viewed along its axis, the eye sees a circle but when the hole is viewed off-axis the eye sees a tube (16), so providing visual evidence of mis-alignment. The plate (30) can be mounted in the focal plane of an eyepiece (20) of an instrument, such as a telescope, microscope or gunsight, so that the axis of the hole (32) is coincident with the optical axis of the instrument. Alignment of the instrument with a desired target can be attained on the basis of observation of the circle/tube condition. <IMAGE>

Title: Hydrocracking of heavy oils in presence of dry mixed additive
Inventor: DE BRUIJN THEO J W
IPC: C10G47/26
Filed: 1984-02-03
Abstract: In an process for the hydrocracking of heavy hydrocarbon oil, such as oils extracted from tar sands, the charge oil (10) in the presence of an excess of hydrogen is passed through a tubular hydrocracking zone (13), and the effluent (14) emerging from the top of the zone is separated (15) into a gaseous stream (18) containing a wide boiling range material and a liquid stream (16) containing heavy hydrocarbons. The hydrocracking process is carried out in the presence of an additive consisting of finely divided coal or other carbonaceous material dry mixed with a compound of a metal e.g. catalytically active metals such as iron, cobalt and molybdenum. The additive is slurried with the charge stock and has been found to greatly reduce coke precursors and thereby prevent the formation of carbonaceous deposits in the reaction zone while also being effective in reducing the sulphur concentration of the product. <IMAGE>

Title: Digital instrumentation apparatus for the linear air-track
Inventor: HOOKES DR D E
IPC: G01D5/36
Filed: 1984-07-05
Abstract: Digital instrumentation apparatus for a linear air-track, for measuring the position-time curves of several air-track vehicles (ATVS) simultaneously, comprises a transmission or reflection linear aperture array TA which can be rigidly attached to an ATV, a narrow beam source S of electromagnetic radiation, and a detector D for this beam. Digital pulse-timing circuitry and an interface for linking to a memory associated with a digital computer are also provided. The motion of the array across the beam causes the beam to fall intermittently on the detector which is, therefore, caused to emit voltage or current pulses. The digital circuitry measures the sequences of time interval between successive pulses and stores them in the digital memory. These intervals, together with the accurately known set of repeat spacings of the array, allows the position-time curves for an ATV to be deduced and displayed by a digital computer. Further processing of the data is also possible. <IMAGE>

Title: Procedure for manufacturing a thermally insulating sheath or duct for a pipe or pipes
Inventor: BRENNER JOHAN
IPC: B29C48/90
Filed: 1984-02-03
Abstract: Procedure for manufacturing a tube of insulating material comprising one or several inner tubes (17), a foamed plastic insulation (18) and a plastic surface layer (16). In the procedure, foaming material is conducted to encircle the inner tube (17), and similarly plastic raw material to form the surface layer (16), and around the inner tube (17) are formed the foamed plastic insulation (18) and the surface layer (16) simultaneously in one work step. The surface layer (16) is cooled to desired dimension in a calibration means (14) in which a calibration pressure is produced by the foaming process, the release of this pressure being prevented by the plug which the foam forms as it solidifies. Control of the calibration pressure is effected by regulating the foam raw material supply and the temperature of the raw material.

Title: Clutch disc with torsional vibration damper
Inventor: SCHIERLING BERNHARD
IPC: F16F15/123
Filed: 1985-05-20
Abstract: A clutch disc with torsional vibration damper, in which individual springs 7 for the under- load range are provided on both sides with spring cups 12 in each of which there is arranged a spring 13 for the idling range which is supported both on the bottom of the spring cup and in an aperture 14 of the window in the hub disc. This construction offers a space- saving accommodation of the torsion springs for the idling range and these do not have to be made longer than necessary according to their design, so that their centrifugal force loading and their consequent deflection in the radial direction can be kept very slight. It is further proposed to provide entraining elements 24 in the cover plates so that the torsion springs for the idling range which are in each case not loaded are held in the circumferential direction over the entire range of rotation angle. <IMAGE>
