IPC: G02B21/14
Filed: 1952-07-17
Abstract: 727,057. Phase microscopes. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 15, 1953 [July 17, 1952], No. 18085/52. Class 97 (1). An interference microscope comprises an illuminating system, a partial reflector for dividing an incident beam into a reflected and a transmitted beam directed in opposite directions around an annular loop, a condenserobjective combination including an object plane within the loop and means for producing mutual reversal of the images of the object formed by the two beams, the illuminating system being decentred with respect to at least one member of the condenser-objective combination so that the beams recombine at an exit point on the partial reflector spaced from the entry point to allow phase-changing and intensity-changing means to be located in one or both beams to allow adjustment of the interference fringe system. As shown, the illuurinating beam from a reflector 1 passes a compensator 2, such as an angularly rotatable plate, and is divided by a partial reflector 4 into a reflected beam b passing back through the compensator 2 and reflected in succession by reflectors 8, 7, 6, 5 arranged in spiral form, and a transmitted beam a passing in the opposite direction around the same path and reaching the reflector 4 after passing a second compensator 3. The beams a and b pass a condenser-objective combination 9, 10 enclosing an object 11, at least one member of the combination being decentred with respect to the illuminating beam so that the beams a and b recombine at the point x of the partial reflector 4 spaced from the point of incidence y. Images 13, 14 of the object are formed in the eyepiece 12 together with interference fringes 15 which, by suitable adjustment, may be made to coincide with one of the images. Adjustment of the compensators 2, 3 effects variation of the fringe system. The mirrors 5, 6, 7, 8 may be replaced by a suitable lens system or by three mirrors perpendicular to a common plane to ensure the necessary rotation of the images. Specification 645,464 is referred to.

Abstract: 1430187 Saw blade construction STORA KOPPARBERGS BERGSLAGS AB 17 April 1973 [20 April 1972 26 Sept 1972] 18566/73 Heading B5L [Also in Division B3] Saw blade stock comprises a composite strip consisting of a flexible steel backing strip joined edge to edge with a tooth strip of cutting tool steel, the joint extending across said edges and having a fine grain obtained as a result of dimensional reduction by heat working. The stock may be used for hack or band saw blades with the teeth being formed in at least the cutting tool strip by cutting and grinding or by milling. To product the stock, pieces 1 of the backing strip steel are placed vertically in spaced parallel relation and the sides and bottom of the space 2 between them are closed by steel plates or water-cooled jackets 3, 4 and a plug 5. Consumable electrodes 6, 7 are then placed in the space 2 and current applied to melt the electrodes so that drops therefrom form a molten bath 11 which sets into an ingot 12. The heat produced also causes some of the material of the plates 1 to melt and alloy into the ingot 12 so that it is of the desired cutting tool steel formula. The ends of the electrodes, the drops, and the bath 11 are protected from the atmosphere by a melted slag 8, or by an inert gas, such as nitrogen or CO 2 . The three part billet produced is hot rolled, annealed, cold rolled, and annealed to form a strip having a breadth at least double that of the saw blade stock, and its central cutting tooth steel portion is then divided longitudinally before forming into saw blades.

Title: Improvements in or relating to the manufacture of laminated sheet material
IPC: D06N3/00
Filed: 1956-06-15
Abstract: 820,375. Laminating; coating webs. TOSCONY FABRICS Inc. June 15, 1956 [June 16, 1955], No. 18621/56. Class 140. [Also in Group XVI] A laminated sheet material is formed by applying a plastic cement in deposits spaced uniformly over and across the surface of a material, applying a sheet of backing material to the cemented surface of the first material, when the cement is still in the form of spaced deposits thereon, and advancing the plied material whilst applying pressure thereto to coalesce and heat thereto to set the deposits. As shown, a web of material unwound from a roll, 31 passes around a spreader roll 34 and through the nip between a resilient, e.g. rubber-covered, roll 17 and an adjustably mounted roller 10, the surface of which, having numerous small cavities, picks up adhesive from a trough between a blade 25 and the roller and applies it in spaced deposits on the material. The adhesive coated material then passes around a spreader roll 36 together with a backing web from a roll 37 and the resulting composite web, in which the two layers are united by the partly coalesced deposits of adhesive, is led around a heated drum 42 to set the adhesive, being pressed thereon by an adjustably mounted roller 52 which causes the adhesive to spread into a continuous film. The laminated web, after passing between the drum and an adjustably mounted pressure roller 63 is drawn from the drum between a cooled roller 69 and roller 70, and passes around further cooling drums 78-80 before being wound up at 72. A layer 61 of transparent polyester resin from roll 60 may be pressed on to the drum 42 by roller 56 before the composite web is applied to the drum. It becomes united with the composite web and its surface may be modified by forming roller 69 with a matted or embossed surface. The material on roll 31 may be paper, sheet PVC or similar plastic, or paper having on at least one face thereof a layer of plastic material such as vinyl plastic, the surface of the paper adjacent to the plastic layer being either coated or uncoated and printed or unprinted, the opposite face being plain, resin impregnated, or adhesive coated. Fabric may also be used, in which case the face of the fabric abutting on to the plastic layer would be coated with an additional layer of the cement.

Lateral movement of the axles is prevented by vertical arms 11 engaging rollers 12 spring mounted on the frame 8. The rollers may be mounted on the axle. The axles support the frame through links 14, levers 15, and flexible connections to cams mounted on shafts 18 connected by spiral springs to worm wheels which may be rotated by worms 22 to tension the spiral springs and adjust the height of the body.

Title: Scanner

Filed: 1974-04-30
Abstract: 1464466 Scanning apparatus for photo-electric detection of objects POST OFFICE 30 April 1974 18886/74 Heading G1A A scanning arrangement for use in detecting the presence or absence or measuring the dimension of objects, e.g. parcels on a conveyer belt, comprises a light source, located on one side of the path of movement of the objects, and on the other side a fixed sensor in association with focusing means for focusing light on to the sensor, the focusing means including at least one aperture in a rotatable member, the scanning arrangement having means by which the effective angular extent of the sensing field may be limited so that e.g. false identification of the absence of radiation as being due to presence of an object, is prevented. The focusing means comprises a plurality of lenses 11 mounted in a rotatable cylinder 12 as in Figs. 2 and 4. The objects to be sensed interrupt light from an elongated source 18, Fig. 4, as they pass. The limitation of the angular field may be by means of a mirror 26, Fig. 4, the additional extent of the angular field defined by the distance between two lenses being illuminated by additional source 24 and accurate adjustment being with the aid of shield 27. Alternatively, an additional source 14, Fig. 2, illuminates additional detector 13 via scanning lenses, the walls of box 15 being adjustable to define the angular field since the output of sensor 13 is used to gate the inverted output of the main detector 10. This detector may be a photodiode associated with a trigger circuit. The source may be underrun to match its omission wavelengths more suitably to the detector spectral sensitivity. The rotatable housing may be replaced by a rotatable disc. The observed field may be divided into sectors by appropriate construction and sectoring of box 15 of Fig. 2.
