The device is intended for use in an air heating or conditioning heat exchanger in a dwelling or in a motor vehicle. As shown, the heat exchanger comprises finned tubes 8 extending between headers 9, 10. The bearing plate 12 is mounted centrally of the tube length and has an integral boss 17 in which the shutter 25 is pivoted, the shutter being actuated by a rod or cable 30 passing through a channel 21 in the bearing plate. Two end bearing plates 22, 23 are provided or alternatively the end bearings may be provided by bosses on the tube headers (Figs. 6, 7). In this latter embodiment, the shutter is in two interconnected parts (43, 44) extending respectively over each side of a central bearing plate. In a relatively short-length heat exchanger the centre plate 12 may be omitted the shutter mounting being provided by plates such as 22 or 23 one or other of these having a channel therein for the rod or cable 30.

Abstract: 1,125,461. Displaying characters on cathode ray tubes. ERICSSON TELEPHONES Ltd. 9 Dec., 1965 [29 Jan., 1965], No. 3953/65. Heading G4H. Each spot on the raster of a cathode ray tube is uniquely represented by a combination of the outputs from three bi-stable devices in each of two counters, the combination of outputs being used to control the beam current of the cathode ray tube. To display, for example, the character 4 on the screen the fourth column (22-28, Fig. 1, not shown) is displayed by applying the output of the first and second bi-stable devices (D4, D5, Fig. 2, not shown) in the second counter to an AND gate G2 (Fig. 3). Similarly the fourth row is displayed by applying the "1" outputs from the first and second bi-stable devices (D1, D2) of the first counter to an AND gate G1. To display the remaining points of the character 4 (i.e. those represented by the numerals 10, 16, Fig. 1) suitable outputs from the bistable devices of the two counters are similarly combined in AND gates G3, G4 respectively. All the outputs from the AND gates are then applied to an OR gate G5 which is connected via a selection switch and amplifier to the control circuit for the beam.

Title: Fly fishing line
Inventor: MARTUCH LEON P
IPC: A01K91/12
Filed: 1961-02-02
Abstract: A fishing line includes a cylindrical core of braided silk or nylon, an adhesive priming coating such as a soluble synthetic rubber of the acrylonitrile-butadiene copolymer dissolved in methyl ethyl ketone or methyl isobutyl ketone and a tapered plastisol coating of polyvinyl chloride having embedded therein hollow microspheroids or microballoons which cause the line to float.  The polyvinyl chloride is dispersed in a plasticizer such as dioctyl adipate, -sebacate, -phthalate or trioctyl phosphate. The microspheroids may be made of ureaformaldehyde or consist of phenolic microballoons or glass microballoons.  The microballoons may be filled with air, helium or nitrogen.  The line is made by passing the coated braided silk or nylon core through a tank containing the plastisol mixture including the microballoons.  The line is then passed in contact with a sizing blade or through a variable orifice to provide a tape.  The line is then passed through a heated zone to cure the plastisol. U.S.A. Specification 2,188,396 is referred to.

Title: Target tracking system
Inventor: HAMMOND EDMUND B
IPC: G01S13/42
Filed: 1954-02-11
Abstract: 761,580. Automatic control systems for radio aerials. SPERRY CORPORATION. Feb. 11, 1954, No. 4117/54. Class 38 (4). [Also in Groups XXXVI and XL (c)] Relates to automatic direction-following pencil-beam radars of the type in which the radar 2 and aerial 1 are mounted on a shaft 4 for rotation about a traverse axis V under the control of a traverse servo 10 and the shaft 4 is journalled in a gimbal 3 which is mounted on a shaft 5 for rotation about an elevation axis E under the control of an elevation servo 12, the servos 10 and 12 being controlled by traverse and elevation error signals generated in the radar 1. In order to track the target through a complete hemisphere the gimbal 3 must be able to rotate through 180 degrees about the elevation axis E and when the target passes through the vertical plane containing the elevation axis E the scanner will " turn on its back " ; furthermore when tracking low altitude targets passing through said vertical plane the gimbal 3 must rotate very rapidly about the axis E. According to the present invention these disadvantages are avoided by pivoting the elevation axis shaft 5 in a yoke 6 which is mounted on a shaft 7 for rotation about a vertical train axis A, the angular position of the yoke 6 about axis A being controlled by a high-power low-precision electrical or hydraulic servo 15, e.g. as disclosed in U.S.A. Specification 2,704,489, actuated by an error signal proportional to # secant # where # and # are the traverse and elevation angles respectively so that the line of sight is maintained substantially perpendicular to the plane of the gimbal 3; the control exercised by servo 15 may be such that the traverse angle # never exceeds 40 degrees. The rotation about the elevation axis E may now be restricted to the range 0- 110 degrees. Since the rates of rotation about the traverse and elevation axes V and E are now reduced, servos 10 and 12 may be highprecision low-power hydraulic or electrical systems. The error signal for the train servo 15 is generated by a potentiometer 20 geared to the traverse shaft 4, the output from the potentiometer being applied through a secant multiplier 21 geared to the elevation shaft 5. This multiplier may comprise a specially wound potentiometer or, as illustrated in Fig. 2 (not shown), a negative feedback amplifier whose feedback path has a cosine transfer characteristic. If the target passes overhead, the train angle must change rapidly and this is effected by applying a large amplitude " slewing " signal to the train servo 15 when the angle of elevation # reaches 90 degrees the application of the slewing signal being initiated by a switch 23 actuated by a cam on shaft 5, Figs. 3 and 4 (not shown), and the sense of the signal being controlled by relay circuits 50, 51 and switch 24, Fig. 3 (not shown) according to the sense of the traverse angle # so that yoke 6 rotates in the required direction.

Abstract: 693,891. Pressure cookers. NATIONAL PRESSURE COOKER CO. Feb. 15, 1949 [Nov. 2, 1948]. No. 4161/49. Class 123 (i). The cover 12 and body 11 of a pressure cooker are secured together by a plurality of co-operating pairs of interengageable elements 27, 32, the elements 27 on the cover, say, having two projecting portions 28, 29 with an intermediate relief area or recess 30, and those 32 on the cooker body two projecting portions 35, 36 and two recessed portions 37, 38 alternating with each other. The arrangement is such that with the elements 27, 32 fully engaged, Fig. 2, an internal sealing ring 23, Fig. 3, is secured in fluid-tight relation between the cover and body, but upon rotation of the cover with respect to the body in the direction of arrow B, Fig, 6, the projections 28, 29 move into the recesses 37, 38, thus allowing the cover and body to separate axially to permit release of the pressure within the cooker and preventing further rotation and consequent separation of the two parts until this pressure is released. The projection 36 may be recessed slightly relatively to the projection 35 as shown in the modification, Fig. 8, where the cover is provided with a single projection 28', so that, after release of the pressure in the cooker by engagement of the projection 28' and recess 37, engagement of the projections 28<SP>1</SP>, 36' will not effect. sealing of the cover and body. Rotation of the cover in the locking direction is limited by the abutment of an upwardly-projecting pin 40 on the body against one of the lugs 28. Specification 645,945 is referred to.

As shown, the expanding and contracting group of rollers consists of three rollers 20, 20<a>, 20<b> mounted in bearings 21 slidable in guides 22 in side frames 11. The bearings are provided with trunnions 24 connected by links 28 to nuts 27 on a screwed shaft 34 operable by a hand-wheel 33, The threads engaged by the two nuts 27 are preferably of the same direction and pitch so that, on turning the wheel 33 in either direction, the rollers are expanded at one side and contracted at the other. Idler rolls 30, 30<b>, 30<c>, which may be mounted similarly to the rolls 20, 20<a>, 20<b>, are provided to cause the fabric to embrace a considerable part of the circumference of the rollers 20, 20<a>, 20<b>.
