Abstract: 1510826 Heat exchange apparatus INTERNATIONAL HARVESTER CO 22 May 1975 [22 May 1974] 22323/75 Heading F4S [Also in Division B7] A cooling assembly comprises an annular radiator 16 having radially extending cooling air passages therethrough, an axial-flow fan 28 and a shroud 38. The shroud is so shaped that, when the fan is rotated in one sense, air which passes axially through the shroud is directed (at least in part) radially outwards of the shroud towards the interior face of the annular radiator. The shroud has a cylindrical throat section 40, Fig. 3, an annular radially extending flat flange section 44 and an annular intermediate section 42. Optionally, the shroud supports a bell-mouth entrance 66. The fan blades 28 extend axially from a first plane, which is substantially coincident with one end of the cylindrical throat section 40, to a second plane which is substantially coincident with the plane containing the juncture of the intermediate section 42 and the radial flat flange section 44. For the shroud and fan blades RF=AW/3, CF=AW/3 and R= 2AW/3 where RF is the radial length of the radial flat flange section, CF is the axial length of the cylindrical throat section and R (see Fig. 3) is the radius of curvature of the intermediate section. Fig. 6 shows a modification where the cooling air is drawn through the annular radiator 16 and the shroud 38 is reversed in its location. An additional round heat exchanger 81 is provided. In the apparatus shown in Fig. 1, parts of the shroud's radially extending flange section are omitted, as illustrated in Fig. 7 (not shown), so that some of the air flows axially to a flat radiator 71. Barriers may be provided as at 73, Fig. 1, or in the region of the fan hub as at (68), Fig. 4 (not shown). The cooling assembly may be applied to any portable or stationary device. As shown in Fig. 1, the annular radiator 16 is in a truck and is for cooling of water from a water-cooled I.C. engine 10. Additional radiators, such as the radiator 71, may be provided for cooling of hydraulic fluid or of air-conditioning fluid employed in the vehicle. Instead of providing additional radiators, one radiator core may be divided into different sections each for the cooling of a different liquid.

Filed: 1958-07-15
Abstract: 846,537. Thermal switches. LANDIS & GYR A.G. July 15, 1958 [July 26, 1957], No. 22665/58. Class 38 (5). [Also in Groups XI, XIII and XXXVI] A thermal control device suitable for use with multiple-tariff electricity meters (see Group XXXVI) comprises an insulating body 3 pivoted on a shaft 2 and carrying a bi-metallic strip 4 with a rigidly connected heater 5 made of material which softens on heating (see Group XI), and a bi-metallic compensator pack 18 guided in an opening 19 of the base 21. A rocking arm 7 pivots about shaft 2 and is connected by a pin 6 to the strip 4 and by a tension spring 9 to a U-shaped control lever 11 pivoted on each arm by a shaft 12 and normally abutting a stop 13. When the heater 5 is energized the strip 4 flexes downwardly to cause the lever 11 to snap over against stop 14 and actuate a switch by means of a lateral extension 15 projecting through an opening 16 in the housing. Alternatively the device, which is self-resetting, could act as a single-pole, change-over switch by making circuit connections to members 12, 13, 14 and using lever 11 as the switch blade. Room-temperature compensation is produced by rotation of the body 3, and the use of a plurality of compensating members serves to limit rotation of the body 3 during operation, so reducing the operating time.

Abstract: 1466125 Pinhole detector ALUMINUM CO OF AMERICA 21 May 1974 [6 June 1973] 22699/74 Heading G1A Small holes in opaque materials are detected by directing a pulse of radiation at the material and detecting any radiation that passes therethrough. The radiation is in the range 2,000 to 20,000 with preferably at least 50% of its energy in the range 2,000 to 4,000. It is preferably supplied from a zenon gas source fired by a capacitor discharge system giving an energy of at least 1 joule in 3-100 micro-seconds. The system shown is for detecting holes in aluminium foil containers. The containers are placed over holes 22 in light opaque sections of conveyer 20. Adjacent detector 40, each container is sucked into light-tight engagement with conveyer 20 by vacuum means 50 and source 30 is then triggered. If light reaches detector 40, the container is faulty and is removed by reject mechanism. The detector may comprise a filter so that it responds to only certain wavelengths in the source radiation. In an alternative embodiment, the detector may be above conveyer 10 which has holes for carrying lids to be tested and the detector is surrounded by an extensible, light-tight tube which is moved to contact the conveyer. The conveyer may also comprise a rotary table. Measurements may be made at the rate of 10 per second with the samples either moving or stationary during measurement. The radiation must contain wavelengths shorter than the dimensions of the smallest hole to be detected.

Title: Improvements in the manufacture of an asphaltic product
IPC: C08L95/00
Filed: 1933-08-14
Abstract: "Sugar scum" or "carbonation mud," which is a residual product of the purification of sugar juices, e.g. beet, is mixed with bitumen which melts between 40 and 65 DEG  C. such as petroleum bitumen.  The scum contains precipitated calcium carbonate and flocculated colloidal lime salts such as lime pectate.  The mixing may be performed by adding the scum in the form of an aqueous paste or a dry powder to an aqueous emulsion of bitumen, the mixture being then dried and pulverized; or by grinding the bitumen after cooling or pulverizing, after heating, with a jet of air, and then adding it to the aqueous paste.  The grains or drops of bitumen are said to be coated with particles of the scum, so that the mixture can be kept in a granulated form.  Mixtures containing upwards of 20 per cent of bitumen can be obtained.  To p  the mixture may be added, for making a road composition, cold or hot tar or heavy oils derived from coal or petroleum and aggregates such as sand, gravel and slag.  The Specification as open to inspection under Sect. 91 contained references to the use of finely-divided substances other than sugar scum for mixing with bitumen, whereby, it was stated, the bitumen particles were coated.  This subject-matter does not appear in the Specification as accepted.

Title: Temperature compensator for a machine tool component
IPC: B23Q11/00
Filed: 1969-05-05
Abstract: 1,213,595. Programmed control of machine tools. KEARNEY & TRECKER CORP. May 5, 1969 [May 6, 1968; Feb.3, 1969], No.22741/69. Heading G3N. [Also in Division B3] In a machine tool positioning system temperature compensation is provided by modifying the control signal according to the temperature measured at at least one point. The machine has a spindle 28 which is positioned in three axes by a programme tape 50, but compensation is described for the Z axis only. A position transducer produces a sinusoidal signal whose relative phase angle represents the position of a spindle carriage 25; this is compared in phase at 55 with the signal from tape reader 50 and the difference controls a positioning motor 38. Thermal expansion between the transducer and the end of the spindle would result in an erroneous position B, but the temperature at 58 is detected by a thermistor connected to an RC circuit which applies a correcting phase shift to the sinusoidal position signal. The resistance in the RC circuit is adjustable for setting-up purposes. A further phase angle adjustment, in the opposite direction, may be made by a second thermistor and RC circuit which measures the ambient temperature at 62. Thus, in this embodiment, compensation is made for the amount that the spindle temperature exceeds ambient.

Switching systems. - Electric switching arrangements for use in controlling motors operating coal cutters &c., in which a trailing cable with plug couplings at each end, connects the motor to the supply are provided with an electrically - operated starting switch or switches at the supply end which can only be closed when the couplings are in position and which is controllable by a switch on the machine. As shown in Fig. 1, electromagnetically operated switch G connects lines 1 - - 3 of the supply cable A to a three phase motor through a trailing cable C having plug connections B, D, at its ends. The circuit of the switch operating coil H is completed across the supply mains through switches E and F and auxiliary lines 4 and 5, the switches being arranged to lock the plug connectors in position when closed, thus ensuring that the plug contacts cannot be exposed when alive. In Fig. 2 the auxiliary switch operating circuit is fed from the secondary of a transformer K the primary of which is connected across the mains by the switch E and the secondary through the switch F and lines 4 and 5. In Fig. 3 the return path for this secondary circuit is through the machine frame and cable armouring. Fig. 4 shows a further modification in which the circuit of the closing coil H of the electromagnetically operated switch is completed across the mains by a relay N the circuit of which is controlled in the manner already described in connection with the coil H of Fig. 3. The switches E<2>, and F<2> in this form not only control the auxiliary circuits at E<1> and F<1> but also carry bridging members of main and reversing switches in the line circuit. The relay N may engage a mechanical interlock P for preventing the switch G from closing otherwise than by the action of the coil H.
