Title: Method of heating flat strip stock and furnace therefor
IPC: F27D99/00
Filed: 1976-12-06
Abstract: 1533309 Continuous heat treatment furnaces THERMO ELECTRON CORP 6 Dec 1976 50788/76 Heading F4B Flat metal stock 15, in the form of strips, slabs or sheets, is heated in a continuous heat treatment furnace 10 both by radiation from a series of perforated refractory plates 26 and by direct impingement of jets of combustion products issuing from the openings 28 in said plates 26. The plates 26, which serve to separate the heat treatment chamber 17 of the furnace from a plurality of combustion chambers 22 positioned thereabove, are arranged in a common plane which is parallel to but spaced from the confronting flat surface of the metal stack 15 to be heated. The openings 28 in each plate are uniformly distributed, and each combustion chamber 22 has an associated burner 24 which is supplied with combustion air via an inlet pipe 30 and fuel via a pipe 28. The pipes 28 and 30 are connected to respective common manifolds 32, 34, with air manifold 34 being connected to a blower 36. The operating conditions are such as to ensure that complete combustion takes place within the chambers 22. The combustion products after impingement with the metal stock 15 in chamber 17 are exhausted therefrom through flues 38. Preferably the ratio of l/d is within the range of 10 to 15, where I = diameter of an individual opening in the plates 26 and d is the distance of the plates 26 from the confronting surface of the metal stock 15 being heated. The stock 15 is supported on rollers 20.

Title: Improvements relating to pulse radar systems
Inventor: MCQUEEN JACK GORDON
IPC: G01S13/52
Filed: 1966-11-18
Abstract: 1,272,744. Pulse radar. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 15 Feb., 1968 [18 Nov., 1966], No. 51883/66. Heading H4D. In an M.T.I. radar system, of the single cancellation type, constant noise circuitry, to produce CFAR, precedes the cancellation circuit. Additional cancellation of moving unwanted echoes (clutter), such as rain or chaff, is effected by controlling the delay time of the cancellation system, fractionally off the radar pulse period. Differences in the amplitudes of the cancellation signals, resulting from the constant noise circuitry, are suppressed. In the radar intermediate channel signals due to unwanted echoes are applied to the delay line, 5, and the logical circuit, 10, determines the tapping, on line 5, at which mutual cancellation of the unwanted echoes occurs, the clutter phase zeroing being maintained by the phase channel feedback loop 11, 12, 8. The effect of noise on the moving echo feedback loop is reduced by the amplitude threshold circuit, 13, fed from the amplitude channel 2, 3, 4, 14. The phase channel loop, which distinguishes between clutter and wanted targets, is not adjusted in accordance with the wanted moving target echoes, this is affected by causing the feedback to respond only when the amplitude threshold has been exceeded for a time longer than the moving target echo pulse width. It is shown mathematically that in order to facilitate the cancellation of stationary clutter and to leave the moving target information unimpaired, the square of the lower of the amplitudes of the delayed and undelayed signals is required. This is derived, at 14, in forming the product of the two signals and is multiplied, at the divider stain 15, with the phase information, relevant to the target echoes, provided by the logic selector, 10, at the tapping where the unwanted echo signals are zero. The selection of the appropriate point on chain 15 is effected by the "-through-and" gates, 16.

Abstract: 1,131,845. Rubber bush mountings. GENERAL TIRE & RUBBER CO. 8 Dec., 1965 [11 Dec., 1964], No. 52178/65. Heading F2S. [Also in Division B5] In making a resilient bushing comprising an elastomeric insert 3, which is preferably formed by injection moulding and is oompressibly restrained between two concentric rigid sleeves 1, 2, the insert is bonded to at least one of the sleeves 1, 2 by first cleaning the corresponding surface of the sleeve, e.g. by sand blasting and de-greasing and then applying a primer coating of halogenated rubber and filler dissolved and dispersed in a suitable carrier and allowing the coating to dry by evaporating the carrier, generally a solvent, therefrom e.g. by heating up to 180‹ F. After the primer has dried an adhesive, which contains a diisocyanate, e.g. a benzidine diisocyanate, and a halogenated nitrile rubber, e.g. a chlorinated acrylonitrile rubber, dispersed and dissolved, with various fillers in a suitable carrier, is applied over the primer coating, the adhesive then being dried e.g. by heating to produce a non-tacky surface. The elastomeric insert 3, which is formed by injection moulding and preferably given a surface treatment consisting of an alkaline detergent wash and subsequent drying, is preferably covered with a suitable oil and is then assembled between the sleeves 1, 2 by any of the well known techniques and allowed to wait for several hours to disperse the lubricating oil. The surface between the insert and the sleeve is then heated to a temperature of about 260‹-300‹F. to band the parts together. A duplex bushing, Fig. 3, not shown, comprises three metal sleeves (11, 12, 13) which are treated with a primer and an adhesive in the manner as described above, an elastomeric insert (14) being first bonded to the outer sleeve and then the elastomeric insert (15), previously bonded between the inner and the middle sleeves (12, 13), is introduced into the insert (14) and bonded thereto. This kind of bushing is suitable for high axial loads e.g. heavy trucks etc. One of the contacting surfaces of a bushing may be relieved, or channelled to form a dualrate arrangement and, if desired only a portion of a contacting surface of the air insert need be bonded to a corresponding sleeve. The inner metal sleeve may be replaced by a pin, and the outer sleeve may comprise an outer housing forming e.g. part of a machine or vehicle.
