Abstract: 1342093 Welding by pressure; casting composite articles METHONICS Ltd 3 Dec 1970 [4 Dec 1969 27 April 1970 23 Nov 1970] 57474/70 Headings B3F and B3R [Also in Divisions C7 and F3] An incendiary component for ammunition is made in a process which comprises bonding a solid alloy including, as major constituent, a rare earth metal, to a steel substrate. The alloy (see Division C7) also includes materials selected from carbon, iron, titanium, copper, antimony, tin, zinc, lead, beryllium copper, aluminium and magnesium. The preferred rare earth is mischmetal. The alloy has a density 86% that of steel and possesses incendiary properties. The bonding is effected by cleaning the substrate and casting the alloy in contact with the cleaned surfaces. The alloy may be cast onto a single surface or between two opposing surfaces. Following solidification of the alloy an additional step of heating at 800-1300‹ F. for 6-48 hours in an inert atmosphere may be performed to form a diffusion bond between the alloy and substrate. In an alternative method, the alloy is applied to the substrate in solid form by clamping or by weights and then diffusion bonded thereto.

Abstract: 1359410 Slack adjusters; brake actuators SVENSKA AB BROMSREGULATOR 15 Dec 1972 57896/72 Headings F2E and F2F A slack adjuster preferably incorporated in a compressed air actuated brake actuator comprises a rotatable adjuster spindle 9 having a non-self-locking threaded engagement with an adjuster nut 26 a rotatable push spindle 15 having a self-locking threaded engagement with a push rod 16, and means joining the two spindles consisting of two-one way clutches, respectively, comprising spring 20, locking sleeve 21 and locking spring 22, and locking collar 18, locking springs 23 and spindle 15. On brake application a piston 5 moves rightwardly which movement is transmitted via piston rod 8, a locking ring 19, coupling spring 24 thrust bearing 25 and spindle 15 to push rod 16. When nut 26 has moved a set distance A it engages a sleeve 20 which prevents further axial movement thereof so that the spindle is caused to rotate in the non-locking direction for the first one-way clutch 20, 21, 22. No torque is transmitted to spindle 15 which is locked against rotation by the second one way clutch 18, 23, 15. When the brake lining has been applied a counter force acts on push rod 16 and spindle 15 causing spring 24 to collapse and spindles 9, 15 to abut thereby directly transmitting the brake applying force from spindle 9 to spindle 15. Nut 26 follows movement of spindle 9 under the compression of a spring 29. On brake release springs 24, 29 expand and nut 26 retains its position on spindle 9 until it is stopped by a ring 31 carried by the adjuster extension housing 2<SP>1</SP>. On further release spindle 9 is thereby caused to rotate in the torque transmitting direction of the first one-way clutch so that spindle 15 rotates and causes push rod 15 to move rightwardly to take up slack. The distance A may be adjusted by unscrewing a bolt 28 and rotating a sleeve 27 screwthreaded to the adjuster extension housing 2<SP>1</SP>.

Title: Method of burning liquid fuel
IPC: F23K5/10
Filed: 1978-11-16
Abstract: A method of burning liquid fuels in a gaseous fuel burner, includes the steps of atomizating the liquid fuel oil, mixing the resultant spray with a diluent gas, heating the mixture of fuel droplets and diluent gas so as to completely vaporize the liquid fuel, and flowing the resulting oil vapor- diluent gas mixture to the orifice of a conventional gas burner. Primary air is induced into the burner tube due to the high velocity of jets of oil vapor- diluent gas. The diluent gas permits low vapor pressure of oil vapor and thus low operating temperature. The diluent gas can be preferably any non- combustible and non-oxygen containing gas, such as steam, nitrogen, carbon dioxide, flue gases or waste gases of low calorific value. <IMAGE>

Title: Tightening a threaded fastener
IPC: B25B23/145
Filed: 1978-11-24
Abstract: In tightening a threaded fastener, a check is made to determine whether a tightened fastener has been turned through the correct angle within limits to achieve the desired tension in the fastener and that the torque used to tighten the fastener to this position is correct within limits. The angle is measured by an angle encoder 18 which emits pulses corresponding to the tool rotation, and the torque is sensed by a torque sensor 11. Angle signals are compared with preset angle values, and are passed to an acceptance logic circuit 36. Torque signals are also passed to this circuit 36, an output therefrom indicating whether the fastened joint is acceptable or is to be rejected. The tool is automatically switched off when a preset angle is reached, by action of a comparator 26, an OR gate 29 and a stop command logic circuit 9. Alternatively, if an upper preset torque limit is reached before the preset angle limit, then the tool is again switched off, and a visual signal of flashing lights indicates this condition. Multiple tools with respective display units may be coupled to a master display unit. <IMAGE>

Title: Controlling cooling systems
IPC: G05D23/22
Filed: 1978-12-01
Abstract: A cooling control system is described which is of particular value in controlling the cooling of various parts of an independent section glass- forming machine. The control of the cooling air which passes through a duct is effected by a combination of a measurement of the cooling capacity of the air (determined by locating in the air flow in or near the duct a heated body and measuring its surface temperature) and the pressure of the cooling air supply. The air flow through the duct is increased or decreased to maintain the pressure in the duct substantially at a pressure set point which in turn depends on the temperature measured at the surface of the body set in the cooling air stream. <IMAGE>
