Title: Heat exchangers
Inventor: KUN L C
IPC: F28D1/03
Filed: 1973-04-13
Abstract: 1424689 Heat exchangers UNION CARBIDE CORP 13 April 1973 [10 July 1972 23 March 1973] 17782/73 Heading F4S A cross-flow heat exchanger (in particular a radiator in which I.C. engine coolant is cooled by an air stream) consists of spaced apart, parallel ducts (e.g. 21, 22, Fig. 15) each of elongate cross-section with a duet width of at least four times the duct thickness, and having on its major wall surfaces externally directed protuberances (e.g. 27, 28) which serve as spacers between adjacent ducts, each duct having also on at least one of its narrower walls a fin (e.g. 23, 24, 25 or 26) which extends longitudinally for the whole length of said narrow wall, the or each said fin being formed with distortions to increase the heat transfer characteristics of the fin. Preferably the or each fin is between 0À005 and 0À015 inch thick, the surface distortions therein extending into the flow space between adjacent fins and covering an area which is at least 40% of the fin surface. The said fin distortions may alternatively comprise (a) slitting the fin and bending the slats so formed into louvres (as shown, see Figs. 5-5D), (b) slitting the fin (Fig. 6) along lines (11) at an angle to the longitudinal axis (x-x) of the duct and pleating the strips (14a, 14b) so formed to provide a turbulating surface for the fluid e.g. air, flowing over the ducts, (c) corrugating the fin (Figs. 7 and 7A), (d) forming dimples in the fin (Figs. 8 and 8A). The external fins may be formed with the duct wall or be separately attached thereto (see e.g. Figs. 1-4A). Where louvres are formed by slitting the fin as at (a) above, the louvres may alternatively be oriented parallel to the longitudinal axis of the duct. Where dimples are formed in the fin as at (d) above, they may be pierced to allow fluid drawn from one side of the fin, to pass through and interrupt the fluid film on the other side of the fin. The externally directed protuberances on the major surfaces of the duet wall may have the contour of a shear-free soap bubble (Fig. 11), where the projection spacing (D) is between about 0À2 and 1À0 inches. Other shapes of protuberance comprising dome-shaped, generally conical, pyramid, square, or circular, are described (Figs. 11A, 13, and 14A-14H). The invention also comprises a heat exchanger generally as described above in which the ducts are of aluminium between 0À003 and 0À015 inch thick, and the duct assembly is mounted in an outer structural frame (e.g. 92, Fig. 24) wherein the ducts extend between inlet and outlet headers (93, 94). The protuberances on the duct walls also comprise load-bearing elements of the assembly wherein the outermost protuberances engage the structural frame. Also in this form of the invention the duet structure must conform to empirical formulµ as set forth in the specification for (a) the individual shape, size and distribution of the protuberances on the duct main walls (see Figs. 14A-14H and 25A-25D), and (b) the relationship between the duct inner surface area and the external surface area of the duct including the fin area.

Title: Improvements in or relating to torque-producing electro-responsive devices
IPC: H02H3/42
Filed: 1944-09-19
Abstract: 597,088. Electromagnetic relays; protective cut - out arrangements. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Sept. 19, 1944, No. 17875. Convention date, Sept. 22, 1943. [Class 38(v)] [Also in Group XXXVI] A torque-producing relay is energised by means responsive to a product, e.g. (E + I) (E - I), of different vectorial sum of E and I where these symbols represent alternating- current functions of line-voltage and linecurrent. A loop 10, pivoted at 11 and carrying a contact arm 19, is energised by flux produced in a core member 7 by current flowing in coils 17, 18. This loop reacts with the flux produced in an air-gap 8 by current flowing in coils 15, 16, mounted on a central leg 5 of the same core. If the flux produced in the member 7 is proportional to (E + I) and the flux in the air-gap 8 is proportional to (E - I), the torque produced is proportional to (E<2> - I<2>) and the relay responds to apparent line-impedance. By proper selection of the exciting-currents in the windings 15-18 and in some cases by the use of a phase-shifter, the relay may be made responsive to reactance or resistance or it may serve as a directional, differential of overcurrent relay. In a modified form, Fig. 3, the voltage and current functions are combined in three-winding transformers 29, 30 to obtain secondary currents Is and ID which produce fluxes in poles 52, 54 and 51, 53, proportional to (E + I) and (E - I). Conducting loops A, B form a pivoted framework carrying the contact-arm 19 and each flux induces a current in one of the loops which reacts with the other flux to produce a torque. The Specfication as open to inspection under Sect. 91 comprises also a reference to the omission of one or more of the windings shown in Fig. 1 in order to obtain reaction or directional response. This subjectmatter does not appear in the Specification as accepted.

[Class 40 (iii)] A tape transmitter is built by unit construction so as to comprise groups of parts which can readily be removed and replaced. The marking and spacing spring terminals 42, 44, Fig. 2, are connected to pillars 28, 29 having contact points 33 engaging contacts on a lever 32, Fig. 4, which stays put under togglowise pressure applied through a blade 31, Fig. 4, from a spring 34 acting on a lever 27. These parts are mounted on a bracket 24 to form a unit which can be fixed into a panel 8, Figs. 1, 2, the pin 41 and dowels 40, Fig. 4, entering recesses in the panel, and the springs 42 ... 44, Fig. 2, establishing the circuit connections. The lever 32 is rocked to the marking and spacing positions respectively by extensions 12a, 12b, Fig. 1, of two rocking levers 12, Fig. 2, each of which carries a tape-feeler 11. The levers are rocked by cams 20 which are made of hard-wearing fibrous material and bear downwards and upwards upon replaceable wearing bars 23, 19, the bars 23 being on the rocker bars 12 while the bars 19 are in sleeves 17 carried by the upper limbs 16 of springs 14, each of which engages under a rocker bar 12 and takes a turn round a pivot 11a. The tape is held down on a tape-guide 1 by a pivoted weight 2 and is fed by a feed-wheel 5 on a shaft 7 which extends through the panel 8 to a pinion 9, Fig. 1,-which is driven by a pinion 22 on the shaft 13. The latter shaft carries the rocker cam 20 and is driven through flexible shafting and an infinitely variable friction gear by a motor which is mounted on slides, Fig. 5 (not shown), and can be shifted by a feed-screw so as to vary the gear ratio and consequently the speed of operation of the transmitter. The motor and gear are on a base-plate which carries the external terminals, to which the motor can be connected through flex and a plug and socket. The signal circuit is completed through spring contacts when the panel 8 is mounted on the base-plate and there held by pins and sockets.

Title: Improvements in or relating to Apparatus whereby the Mean Gauge of a Wire, or other Cylindrical Body of Small Diameter, can be Ascertained.
Inventor: RYMER-JONES JOHN
IPC: G01B5/08
Filed: 1918-11-01
Abstract: 125,891. Jones, J. Rymer-. Nov. 1, 1918. Computing - apparatus; cubical contents; measuring.-An apparatus for obtaining the mean diameter of a known length of wire or other cylindrical body, without detachment from the main body thereof, from the quantity of mercury displaced by its immersion therein, consists of three glass tubes a<1>, b, c screwed into a base and connected by a channel g, taps d, c, f being provided at the bases of the tubes. Of the three tubes, the tubes b, c are used for all operations, but the tube a' is replaceable, one of a diameter approximating to that of the wire to be tested being used. The tube c is of the greatest diameter and serves as reservoir for the mercury, the tube b is provided with an adjustably mounted scale, and the tube c is formed with a notch o, the lip l of which is level with the zero point of the scale. A versel r supported on hooks h is provided to catch the mercurv which overflows at the lip l. In operation it is necessary first to calibrate the device, and this is done by first filling all the tubes with mercury until the lip and the zero scale reading are reached, final adjustment being given, after the tap f of the reservoir has been closed, by means of a screw m projecting into the passage g. A standard length of wire of known diameter and specific gravity is then held immersed in the liquid by an adjustable holder y, the displaced mercury collected in the vessel r is weighed and the scale reading in the tube b noted when the wire is withdrawn. From data resulting from the employment of a number of wires of different diameters with the various scale tubes, tables and curves are compiled and the diameter of a wire can be determined from the reading of the mercury level in the scale tube b after the removal of the wire from the gauging tube a', the standard length of the wire having been marked thereon prior to immersion. The device is stated to be particularly applicable for obtaining the diameter of insulated wires in place of the use of a calliper gauge as usually adopted. When used for very fine wires, narrow gauging and scale tubes are employed and the lower end of the fine wire is held by fastening it to a screw s' provided with a hole h<1> and situated at the bottom of the gauging tube down which the wire is threaded after it has been temporarily raided from its base. The gauging tube is not provided with a lip and in operation the scale tube is filled, its tap closed and the mercury adjusted in the gauging tube until the difference in level is equal to the standard length. Both tubes are cut off from the reservoir and the diameter of the wire is calculated from readings taken after the two have been put into communication. Specification 5142/11 is referred to.

Abstract: 743,737. Pens for recording;instruments. KENT, Ltd., G. June 28, 1954 [June 29, 1953], No. 18017/53. Class 146(3) A pen for a recording- instrument comprises a pen arm blade 1 of resilient material, e.g. spring steel, having a cranked portion 3 carrying the nib 2. The nib 2 comprises an ink reservoir 4 and a slit to feed a writing point 5. The cranked portion 3 ensures that the point 5 is approximately in the plane of the blade 1, such that torsion of the blade 1 is substantially obviated, thus ensuring an even movement of the nib over the surface of a chart. In a modification, the nib is attached to the pen blade by means of wires bent to form a U with the nib, such that the writing point lies approximately in the plane of the blade. In a further modification, a second pen is carried by a part which with the second nib forms a U, the distance apart of the legs of the U being as short as possible to minimize the effects of torsion.

Filed: 1954-06-18
Abstract: 796,868. Laminated fabrics. EVERWEAR CANDLEWICK, Ltd., and GLASS, B. June 8, 1955 [June 18, 1954], No. 18031/54. Class 140. [Also in Group IX] A laminated material consists of a facing layer 2 and a backing 1, both of textile fabric, that have been secured together at spaced intervals and then treated to shrink the backing relatively to the facing, and chenille tufts 3 projecting through the facing layer. The shrinkage, which causes the facing to ruckle, may be effected by washing and drying the composite fabric. The layers may be secured together at spaced lines or points by adhesive, by ordinary stitches, or by the tufting stitches whereby the chenille tufts are applied. The backing layer may be of cotton or spun rayon sheeting while the facing layer, which may be applied to one or both sides of the backing, may be of continuous filament rayon, satin or taffeta, or of silk. When both sides have a facing layer tufts may be provided on one or both sides. The colour of the tufts may differ from that of the facing fabric from which they project. The facing fabric may cover the backing completely or may leave part of the backing exposed.
