Abstract: 1311797 Traversing mechanisms LEESONA CORP 6 March 1970 [10 March 1969] 10750/ 70 Heading D1J A traversing mechanism of the kind employing two endless belt spans 40, 42, with each belt moving in a direction opposite to the other, and with each belt carrying yarn engaging fingers 68, is characterized in that the path of each belt is such that the yarn engaging means is directed in a first path as the yarn is traversed onto a first zone of said package, and said yarn engaging means is directed in a second path diverging from said first path as the yarn is directed onto a second zone of the package, one of said paths being substantially parallel to the axis of the package and the other of said paths being inclined relative to the axis of said package. As shown in Fig. 2 the belt span 40 is guided first by wheels 45, 70 that maintain the belt 40 parallel to the package axis, and then by wheels 70, 46 that direct the belt 40 away from the package axis. The yarn Y is then taken up by a finger on the other belt 42, the belt 42 being guided first by wheels 50, 72 that maintain the belt 42 parallel to the package axis, and then by wheels 72, 49 that direct the belt 42 away from the package axis. The belts 40, 42 are preferably toothed belts. The apparatus includes many of the features disclosed in Specification No. 1,269,532.

Abstract: 1,039,192. Electrically released switches; thermal switches. CRABTREE & CO. Ltd. Jan. 25, 1965 [March 16, 1964], No. 10930/64. Heading H2B. An overload switch for mounting on the housing of an electromagnetic contactor 1, as described in Specification 633,393, comprises three cells 5, 5a, 5b, each containing a thermal overload device 7, the centre cell 5a having ventilation openings 6, 6a, 6b in order that the temperatures of the three cells are kept substantially equal. Each overload device comprises a spiral heater connected in one phase line and a cylindrical bi-metal 7 having an arm 7a engaging a pair of slides 10, 10a. Under balanced overload all the bi-metals drive the slides to the left (Fig. 3, not shown), until the lower one strikes an ambient temperature compensating blade 17 when continued movement of the upper slide 10 turns a triangular plate 12 so that a roller 13 thereon acts on a latch 14 (Fig. 5, not shown), to break the connection between the latch and a pivoted arm 22. With unbalanced currents the slides 10, 10a are moved relative to one another to rotate plate 12 as before. The blade 17 is adjustable by a cam 19 and the position of contact arm 22 by a screw 30. The switch is reset by depressing a plunger 31, an arm 32 thereof acting on contact arm 22. If a screw 33a is screwed into the housing so that it holds contact arm 22 in its on position the device acts as a simple self-resetting thermal switch. A back contact 29 for the arm 22 may be used to operate an alarm circuit (not shown).

Abstract: 1375906 Radomes SUMITOMO ELECTRIC INDUSTRIES Ltd 9 March 1972 [11 March 1971] 11066/72 Heading H4A A sandwich type radome has three layers, the equivalent dielectric constant of the outer layers being equal to the square root of the dielectric constant of the inner layer, in order to reduce transmission losses. The core is made of a substantially non-magnetic dielectric material and the thickness of each outer layer is an odd number multiple of #/4 (#= wavelength in the layer at the operating frequency). As shown, the outer layers are in the form of strips 2 of dielectric material arranged upon the surfaces of the inner layer 1, and parallel to the electric field vector. The width W of the strips and their pitch P are chosen so that the required equivalent dielectric constant is obtained. The material of which the strips are made may be the same or different from that of the inner layer, and they may be attached thereto by means of an adhesive; alternatively, they may be formed from a sufficiently thick plate by machining or moulding (Figs. 6(a-c), not shown). The thickness of the inner layer may be an odd number multiple of a quarter of the wavelength therein at the operating frequency. A latticelike or regularly spaced embossed configuration may be adopted for the outer layers in cases where the electric field vector has components in two perpendicular directions.

Abstract: 494,294. Fuel injectors. NYLANDS VERKSTED. April 19, 1937, No. 11151. Convention date, April 21, 1936. [Classes 7 (iii) and 7 (vi)] In a fluid - pressure operated spring - loaded injector, the injection valve 8 besides being under a spring load is subjected, during the latter part of the engine compression stroke, to an additional load due to a fluid pressure. The additional load is applied by a spindle 5 operated from the engine, and is released to allow the valve to open. As shown, the injection valve has a fuel cavity 12 connected with a supply passage 14 by bores 13 and 15. The pressure in the cavity 12 acts on a piston 7 in the valve and normally presses it against a holder 10 for the spring. When the spindle 5 is lowered, the piston 7 is pressed away from the spring holder and an additional load is transferred to the injection valve. The spindle 5 is cam operated.
