Abstract: 852,161. Multiple lamp fittings. GENERAL ELECTRIC CO. Ltd. Dec. 10, 1958 [Dec. 16, 1957], No. 39035/57. Class 75(4). In an electric light fitting comprising a housing carrying a plurality of lamp mounting means spaced around an axis and each associated with a directional reflector, e.g. for use in producing shadowless illumination for surgical operations, each reflector is fixed in the housing and each associated lamp mounting is carried by a movable member linked to a common control member so that the positions of the lamps relative to the reflectors can be varied simultaneously and in the same sense. In the form shown, the housing 1 is of the shape generated by rotation of a triangle around an axis passing through one acute angle vertex and perpendicular to the face through which the light emerges and is carried by a universal joint formed by two yokes 42, 45 in planes at right angles to one another and connected by a pivoted block 44 carrying mutually perpendicular pivot rods 43, 46. Each reflector 2 which may be ellipsoidal or paraboloidal is mounted on the undersurface of the fitting and closed by a window 5. Each lamp 9 is carried a pivoted arm 10 so as to project through an aperture 6 at the apex of the reflector. Each arm 10 is pivoted to the housing at 11 and connected by a rod 16 to a multiarmed plate 22 pivoted on the central axis of the fitting. One arm of the plate 22 has a slot shaped recess 31 in which a roller 32 carried by a pin 33 eccentrically mounted on the control knob 27 moves, so that rotation of the knob moves all the arms 22 and hence the arms 10 simultaneously to adjust the positions of the lamps relative to the reflectors in the same sense. Specification 852,162 is referred to.

Abstract: 1,248,823. Conditioning tobacco. MOLINS MACHINE CO. Ltd. 6 Aug., 1970 [6 Aug., 1969], No. 39274/69. Heading A2C. [Also in Division F4] An inclined rotary drum tobacco dryer (see heading F4G) which may also be used to humidify tobacco comprises shelves 4 which are inclined to the radii of the drum (fig. 3) such that they lean in their direction of motion, the inclination increasing nearer the lower end of the drum. Also provided in the drum is one or more guide members 8 which are chutes occupying central positions in the drum and which slope in the opposite direction to the drum, as viewed from the side. In the case of the humidifier the guides 8 overlap vertically. The operation of the humidifier relies on the fact that dry tobacco will begin to slide down a slope of increasing steepness before wet tobacco so that dry tobacco may slide off a shelf 4 and fall freely in the drum while wet tobacco may remain until the shelf arrives at Y when it falls on to guide 8 which conveys it to a location higher up the drum 1. Tobacco is fed into the drum at its lower end and discharged at the upper end, the drier tobacco spending more time inside the drum than the more moist tobacco.

Abstract: A method of making chrome-nickel steel strip for use in making stainless razor blades comprises successively subjecting an age hardenable austenitic stainless chrome-nickel strip to annealing at 1000 DEG C., cooling it in air or a liquid and subsequently cold reducing it by at least 50% so that the decomposition of the metastable austenite into martensite occurs and whereupon the strip is age hardened at a temperature between 400 DEG C. and 500 DEG C. In a first example, strip having a composition of C 0.1%, Si 1%, Mn 1%, Cr 17%, Ni 7%, Ti 0.7%, remainder Fe, was cold rolled, after annealing at 1000 DEG C. and air cooling, from 0.5 mm. to 0.1 mm. and tempered at 500 DEG C. for 1 hour, to obtain a hardness value of 590 V.P.N.  In a second example, strip comprising C 0.08%, Si 1.20%, Mn 1.20%, Cr 17.50%, Ni 8.0%, Mo 0.8%, remainder Fe, was similarly annealed, cold rolled from 0.9 mm. to 0.1 mm. and tempered at 460 DEG C. for 1 hour to obtain a hardness of 600-680 V.P.N.  In a third example, strip comprising C 0.08%, Si 0.30%, Mn 0.80%, Cr 15.00%, Mo 2.0%, Ni 7.2%, Al 1.0%, remainder Fe, was similarly annealed, cold rolled from 0.7 to 0.1 mm. and tempered at 500  DEG C. for 1 hour to obtain a hardness of 760-770 V.P.N.  The strip or razor blades produced therefrom are ground at 90 degrees to the rolling grain. The strip or blades are coated, e.g. by spraying, with a silicon gel, and heated to improve the adhesion of the coating on the cutting edges of the blade.  The tempering temperature used, e.g. 400-550 DEG C., may be within the temperature range required for the silicon treatment.  An alternative strip composition is given for each of the examples.
