Title: Improvements in control rheostats
IPC: H01C10/20
Filed: 1950-03-01
Abstract: 667,626. Variable resistances. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. March 1, 1950 [March 3, 1949]. No. 5165/50. Class 37. A control rheostat, particularly for use in stage lighting systems, comprises two arcuate or straight resistance elements arranged in parallel, two control levers pivoted at the centre of the arc or on a line perpendicular to the centre line of the straight resistance elements, and a common scale, in which the whole rheostat forms a unit in the shape of a thin disc adapted to be placed within a switchboard, dimmer, &c. by means of abutments on its periphery and to be connected to an outer circuit by contact plugs. A light metal or plastic frame 1 consists of an arcuate portion 2, subtending an angle of less than 180 degrees, with a scale 18 mounted thereon, end portions 3 of T-section, and a transverse portion 4 of rectangular cross-section. Mounted on the frame 1 are two wire-wound resistance elements 5, the resistance wire being embedded in a layer of enamel, a contact path being left free of enamel. The portion 2 has flanges 6 by which the rheostat is fastened to an instrument board or dimmer. The elements 5 have connector lugs 8 connected by leads 9 to plugs 11 carried by an insulating plate 10. Two control levers 12 of insulating material are mounted on conical pivots 13, one on either side of the portion 4, by means of sleeves 14. The conical surfaces adhere by suction, which provides a braking action on the levers. Alternatively the pivots 13 and sleeves 14 may be cylindrical, the braking action being attained by friction surfaces parallel to the direction of movement of the levers 12. Each lever 12 has a window 20 through which projects a contact 16 carried by a leaf-spring 15 by which it is pressed against the resistance element 5. Each lever 12 is pressed towards its pivot 13 by means of a strong leaf-spring 17, which also makes 'electrical contact with the spring 15 and is connected to a contact plug 11. The control levers 12 may be combined with limit switches. The resistance elements may be connected in parallel, or they may have different resistance values and be connected in' series, so that one element serves for coarse adjustment and the other for fine adjustment, the scale then having two calibrations.

Title: Day-night Outside Rearview Mirror Assembly for a Motor Vehicle
IPC: B60R1/08
Filed: 1969-01-30
Abstract: 1,190,726. Rear view mirrors. FORD MOTOR CO. Ltd. 30 Jan., 1969 [12 March, 1968], No. 5176/69. Heading B7J. An external rear view mirror assembly 10 comprises an outer housing 14, an inner housing 22 containing a pair of reflector members, one 28 of relatively high reflectivity, the other 26 of relatively low reflectivity, and an opaque element 34, movable, by manually operated means, to cover the reflecting surface of the former reflector member 28. The inner housing 22 is connected to a ball 18 and shaft 16, to permit pivoting of the inner housing, possibly by a remote control mechanism. The reflector member 26 comprises a transparent glass panel, and the reflector member 28 comprises a mirror having a pair of guides 30, 32 along its longer sides around which is arranged a continuous shade element 34 of matt black fabric in which is cut a window portion 36. A pair of intermeshing sprockets 40, 42 are rotatably mounted on a support 38 (Fig. 4) each sprocket having an attached arm 44, 46 respectively. The arms 44, 46, at their ends remote from the sprockets, have longitudinal slots 48, 50 through which pass pins 52, 54. One end of each pin co-operates with a slot 56, 58 in the support 38 and the other end of each pin is bonded to the shade member 34. A flexible cable assembly, having one end located in the passenger compartment has an inner control wire 62 attached to arm 44, so that movement of the end of the control wire 62 in the passenger compartment causes movement of the arms 44, 46 and hence the shade member 34 is rotated about the mirror 28. A spring, 68 fixed at one end to the support 38, and attached at the other end to the arm 46 tends to retain the assembly in the position shown in which the window 36 in shade member 34 coincides with the reflecting surface of the mirror 28. When the wire 62 is moved, for night driving, the shade member 34 is rotated so that the surface of mirror 28 is covered by the opaque materal, and reflector 26 acts as the mirror, and since it has a reflectivity of about 4%, dazzle is avoided.

[Also in Groups XIII and XXX] Small, compressible particles of material, such as alkali cellulose, are passed for indirect heating or cooling through the annular space 31 between a fixed, cylindrical shell 11 and a cylinder 28 mounted on a rotatable shaft 21, 24 and then the particles are compressed by passing out through an annular passage between non-rotating frusto-conical members 43, 44. The heating or cooling fluid, e.g. water, enters a pipe 24 forming part of the rotatable shaft and passes through a bore in a rod 21 also forming part of the shaft. From holes 23 it flows over the inner wall of the cylinder 28, being directed by a wire 37, wound helically on a second, inner cylinder 33, to holes 38 in a sleeve 25 surrounding and secured to the shaft. From the sleeve 25, the fluid drains away. The particles from a hopper 13 are forced through the apparatus by a helical screw 32 secured to the rotatable cylinder 28. The shaft 21, 24 together with its cylinders 28, 33, is rotated by a pulley 27 and is supported by bearings 18, 19. A framework 15 secured to the outer shell 11 supports both the bearing 19 and, slidably, rods 46 by which the thrust of a fluid-operated piston in a cylinder 49 is transmitted to the frusto-conical member 44 which slides on the shell 11. The resulting axial movement of the member 44 determines the degree of compression of the issuing particles. There may be projections such as pins on the inner surface of the fixed outer shell 11 for stirring the particles. There may be an external cooling jacket on the shell.

Title: Improvements in and relating to apparatus for indicating or controlling the level ofmolten metal in a container
IPC: G01F23/288
Filed: 1949-03-04
Abstract: 681,353. Continuous casting-machines. GERBER, J. S. June 5, 1950 [March 4, 1949], No. 5985/49. Class 83 (i). [Also in Groups XXXV and XL (b)] Apparatus for casting metal includes a container for molten metal and means for maintaining the level therein, said means comprising a radioactive or X-ray emitter and a detector thereof arranged on opposite sides of the container so that when the level rises it reduces the amount of radiation falling on the detector. This may operate an indicator or level controlling means or both. In the machine shown radium &c. in a holder 22 acting through a bottomless mould 11 affects a Geiger counter 23 or the like, the output of which is amplified and smoothed by a device 24 and holds open a switch 26 whereby the current driving a motor 21 passes through a resistance 27 and the roll 17 is driven slowly. When the molten metal rises it obstructs the radiation and the switch 26 short-circuits the resistance 27 so that the roll 17 is driven fast and the level in the mould 11 falls. In a modification the motor is stopped instead of driving slowly, two sources of radiation and two detectors at different levels being used, the lower to stop and the upper to start the motor. Metal-pouring.-In another modification the detector can control the flow of molten metal into the container by operating a motor for adjusting the tilt of a ladle or furnace or the opening of the nozzle 12 thereof. The detector may operate an audible or visible warning, the operator then altering the speed of the molten or solid metal manually if there is no automatic control.
