Title: Transparent supports with low reflection properties in visible light and high reflection properties in the infra red spectrum
IPC: G02B5/20
Filed: 1963-12-12
Abstract: In a method of producing a transparent support with low reflection properties in visible light and high reflection properties in the infrared spectrum, the support is first provided with a semi-transparent thin silver or gold coating, and then a sulphide of a heavy metal, i.e. a metal having a S.G. of more than 5, is deposited thereon to form a silver or gold heavy metal sulphide coating. The support may be glass or transparent plastics foil; it is cleaned, and the silver or gold applied by the rocking dish method or spraying a solution of ammoniacol silver or gold solution, reducing agent and alkali; the solution may also contain up to 2% of platinum and traces of complex salts of nickel, copper, lead, chromium and zinc.  The heavy metal sulphide is then applied from a solution of for example cadmium nitrate and thiourea. An intermediate discontinuous layer of copper may be sprayed on before the sulphide is deposited. The sulphide coating becomes attached to the copper and/or the noble metal by valency bonds to form a noble metal-heavy metal sulphide. In the production of safety glass the coated side is placed against the intermediate layer and for this purpose coatings of silver cadmium sulphide or silver tin sulphide are preferably used.ALSO:In a method of producing a transparent support with low reflection properties in visible light and high reflection properties in the infrared spectrum, the support is first provided with a semi-transparent thin silver or gold coating, and then a sulphide of a heavy metal, i.e. a metal having a S.G. of more than 5, is deposited thereon to form a silver or gold heavy metal sulphide coating.

Abstract: 1,072,270. Rolling. GAUER METAL PRODUCTS Inc. Nov. 29, 1965, No. 50659/65. Heading B3M. Apparatus for deburring the edges of metal strip comprises at least two headstocks 113, 113<SP>1</SP>, Fig. 1, in which rolls (124), (124<SP>1</SP>) are rotatably mounted, each of the headstocks being mounted on a split block (75), (76), Fig. 4 (not shown), and the split blocks being adjustably fixed on pairs of rails 71, 72 or 73, 74, Fig. 1. The pairs of rails are moved relative to each other in the axial direction, so as to vary the distance between the rolls by a hand-wheel 53, Fig. 1. Rails 71 and 72 are connected by blocks 64, 67, Fig. 1, and rails 73, 74 are connected by blocks 65, 68. Blocks 64, 65 are connected by T-shaped levers 22 which are pivoted to brackets (7), (8) at 11, and blocks 67, 68 are connected by levers 56, (57) pivoted to brackets (14), (15) at 18. In operation, the split blocks are set on their respective rails, and laterally spaced strips (137-144) to be deburred, Fig. 2 (not shown), are inserted in the U-shaped grooves of the rolls (Fig. 10, not shown), and loosely held therein. Hand-wheel 53 is operated to pivot levers 22, and the pairs of rails are moved relative to each other, to thus move the rolls (124), (124<SP>1</SP>) together, and grip the strips, which are then passed through the rolls and are deburred. The head stocks can be arranged at 45 degrees to the rails for narrow strip, Fig. 11 (not shown), or they can be arranged at 15 degrees for wider strip (Fig. 11A, not shown). To accommodate strip closely adjacent to each other, a number of sets of rolls X, Y, Z, -Fig. 12 (not shown) is provided, each set operating on alternate strips.

Title: Apparatus for Reducing the Thickness of Metal.
Inventor: SAXL KAREL
IPC: B21B13/18
Filed: 1967-11-09
Abstract: 1,195,115. Rolling. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd. 31 Oct., 1968 [9 Nov., 1967], No. 51102/67. Heading B3M. A pendulum rolling mill includes units for varying the rolling loads acting on the mill, in order to constrain the work rolls to move in more nearly parallel paths and hence produce a rolled product of more uniform gauge. The mill incorporates, on each side of a pass line A-A, an arm which is pivoted at 4 and carries rolls 5 and 6. A driving crank 7 oscillates the outer end of the arm. The pivot 4 is carried on a pair of beams 3 which are adjustable by units 12 about pivots 3a. The units 12 are able to vary the stiffness of the mill as well as controlling the roll gap. Each unit 12, Figs. 3a, 3b, includes a shaft 13 which is threaded into a nut 14, rotation of the nut leading to axial adjustment of the shaft. To vary the stiffness of the unit a sleeve 33 is located within the shaft, a cup 17 at the end of the shaft contacting the sleeve before the shaft when under a compressive force. The sleeve can be pre-compressed to a desired degree by a central tie rod 45. Fluid is conveniently supplied at 52 by a cam driven pump which operates in synchronism with oscillation of the rolls, so that tie rod is stressed at desired points in the cycle of each roll. The resistance of each unit 12 is suitably increased as the rolls move along a work finishing stroke in a direction opposite to that in which the work moves. The normal tendency for the rolls to separate as they reach a thicker portion of the work is reduced and work of more uniform gauge is produced. The tie rods may be dispensed with, and units 61, 62 (Fig. 8) used. Each unit is connected through a throttle 64 with a reservoir 63, and is supplied at 66 with fluid whose pressure is varied cyclically. The point in the rolling cycle at which the auxiliary pressure is applied can be automatically controlled in response to X-ray or gamma ray gauges measuring the rolled gauge of the work.

The material 11 may be a metal foam or a ceramic such as silicon nitride and may be bonded to casing 10 or formed as a loose insert. Casing 10 may be of metal or ceramic such as silicon nitride. Pipes 12 are provided for the supply of oxidant e.g. air, fuel or a fuel/oxidant mixture which flows through the pores of liner 11 to cool the latter before entering the flame tube. The porosity of liner 11 may be graded to effect an increased flow-rate adjacent its internal surface. A nozzle 14 may be used as the main fuel injector, or as a supplementary source when the main fuel is introduced through pipes 12. In a modification Figs. 1, 2 (not shown), a perforated casing (2) is formed internally of the porous material so that the latter is sandwiched between outer and inner casings (1, 2). The flame tube may be cylindrical or annular.

Title: Methods of and apparatus for detecting faults in the filling and the wrapper or cover sheet of cigarettes or other air permeable rod like articles

Abstract: 1,136,478. Testing cigarettes. HAUNIWERKE KÍRBER & CO. K.G. 7 Dec., 1965 [18 Dec., 1964], No. 51812/65. Heading A2C. In a method for testing cigarettes by introducing an air current therein whilst the cigarettes are conveyed transversely to their axes, the filling and the tightness of the wrapper are tested in two steps, and if either the filling or the wrapper is found faulty the test result initiates a control pulse which causes ejection of the faulty cigarette. In one method a first test is made by introducing an air current in one end of a cigarette. The result of this test is affected by both the filling and the wrapper. A second test is made which is affected by the filling or the wrapper only. Testing of the filling only is effected by passing a current of test air through the cigarette and surrounding the wrapper with an airtightseal or by a chamber into which air equal in pressure to that of the test is introduced. Testing of the wrapper only is effected by sealing one end of the cigarette and introducing air at the other or by introducing air at both ends. In a second method a first test is made of the filling only and a second test of the wrapper only. As shown in Fig. 1 cigarettes to be tested are fed from a drum 2 to suction grooves 10 between ledges 12 of a testing drum 8. A first test is made at station P1 by introducing air into a cigarette, the wrapper not being surrounded. The drum 8 also cooperates with a closing drum 14 provided with grooves 16 communicating by ducts 15 with an air current co-operating with the ledges 12 to form a sealed chamber around the wrapper. A second test is then made at station P2. The result of the test is converted into a signal, e.g. as described in Specification 1,083,111, to cause rejection of a faulty cigarette before satisfactory cigarettes are transferred to the drum 20. Suitable devices for introducing air into the cigarettes are described in Specifications 1,016,502 and 1,048,652.
