Abstract: 1,264,084. Teaching and training. HONEYWELL G.m.b.H. 6 Oct., 1970 [14 Oct., 1969], No. 47407/70. Heading F3C. A weapons-training apparatus has a gun sight having controls capable of producing signals corresponding to the aim (i.e. direction and range) of the sight, a computer responsive to the aiming signals and to stored signals relating to at least ground co-ordinates and projectile type for calculating a simulated projectile trajectory, and display means arranged with the sight for superimposing a simulated projectile trajectory on an image that is viewed through the sight in use, the computer being coupled to the display means so as to determine, with corrections for projectile flight time, the trajectory that is displayed. In an embodiment a model is provided with movable targets Z and a sight is mounted in a fixed position, the movements of the sight being simulated by means of rotatable prisms 7, 8. When a gunner 1 looks through an eye-piece a particular section of the model is seen, this being an image 3 and by rotating the prisms 7, 8 by means of a double hand grip 5, the gunner can view any section of the model. A projectile trajectory 4 is superimposed on the image 3, this being produced by means of a computer and being displayed on the screen of a cathode-ray tube 11 in the form of a sequence of spots of light, the latter being reflected by a prism 12, is thus superimposed over the image 3. The trajectory display is produced in such a way that a shot can be fired at any point in an arbitrarily fired area. The firing result obtained corresponds with the actual circumstances of the aiming of the weapon, the type of projectile chosen and the conditions set by the model. Account can also be taken of interference factors selected by the instructor such as barrel wear, loading tolerance, barrel deflection, side wind and tilting. Additionally the brightness of the light trace may be controlled in line with actual conditions, the display can be made immobile, for example, at the point of target penetration, and the ellipse of the projectile scatter area can be inserted at any point in the trajectory display. Thus the gunner can take interference parameters into account when adjusting the sight and the instructor can set conditions and discuss effects with the gunner.

Abstract: 1,266,600. Friction welding. CATERPILLAR TRACTOR CO. 6 Oct., 1969 [20 Nov., 1968], No. 49054/69. Heading B3R. A method of friction welding a first rotatable workpiece 20 to a second non-rotatable workpiece 18 so that the joined workpieces are in a predetermined angularly aligned position comprises initially orientating the two workpieces with respect to each other and also to an indicator means formed as a stop in a spindle 24, rotating the first workpiece 20 to a predetermined speed and then decelerating the rotating workpiece 20 to a predetermined speed and actuating stop means 50 to stop the workpieces in their predetermined aligned position. The rotatable workpiece 20 is first rotated by a highspeed motor 26 via a clutch 28 and the pressure assembly 46 moves the second fixed workpiece 18 until contact is made between the workpieces raising the interface to a welding temperature. Clutch 28 is disengaged and clutch 40 engaged to cause rotation of the flywheel assembly 32 by constant-speed motor 36 and when workpiece 20 has decelerated to a predetermined speed slightly higher than the flywheel speed as determined by a speed recording device 42, clutch 34 is engaged and clutch 40 disengaged. The assembly decelerates to a predetermined speed when a spindle position -sensing device 48 is actuated to record the position of the indicator means and to advance a stop-pin 54 after disengaging clutch 34 to thus stop the workpieces in the originally aligned positions. A forging pressure may be applied to the workpieces by the pressure assembly 46 when the spindle stop 50 is activated. The clutch 40 may remain engaged during the operation such that the motor 36 continues to power the spindle 24 until such time as the clutch 34 disengages. In another embodiment, Fig. 3 (not shown), the flywheel assembly is dispensed with and a constant-speed motor is connected directly to the spindle and is disengaged just prior to actuation of the stop-pin. The spindle may be modified to rotate two workpieces protruding from each end of the spindle.

Upper and lower doctor blades 15 and 16 are fixed to upper and lower plates 13 and 14 and are lightly in contact with the roller 17; and together with the holders 11 and 12, these form a space 20. A U-shaped enclosed passage is formed by bore 23 in holder 12, the space 20, a cut-out portion 24 in lower plate 14, an elongated hole 25 made through plate 14 communicating with portion 24, and a bore 26 in holder 12. Powder is delivered from box 40 by delivery device 50, which comprises a pipe 55 secured between a connector 51 in the powder storage chamber 42 and a connector 53 in bore 23. Pipe 56 is connected in a similar manner. Two helically wound wire coils 57 and 58 having a fixed pitch are provided in the pipes 55 and 56, and connected to connectors 61 and 62 which are fixed to rotary shafts 59 and 60. Coils 57 and 58 act as a flexible feed screw and return screw respectively, so that powder is fed and returned in the direction of the arrows on Fig. 2; both coils rotate at the same speed, but the pitch of coil 58 is greater than that of 57, thus obviating clogging of the powder sprayer. The roller 17, which has notches on its surface, is rotated, and when the powder in the notches is carried near wire 18, it is blown down by an ion wind generated by high tension discharge between the. wire and roller, onto the surface being treated, as a uniform spray. Doctor blade 16 removes any excess powder from the roller.
