Title: Improvements in or relating to damping devices for oscillating elements disposed in an oil chamber
IPC: G04C19/00
Filed: 1937-12-11
Abstract: 504,848. Oscillographs; compensating  instruments for temperature errors; vibration-dampers. KLANGFILM GES. Dec. 11, 1937, No. 34391. Convention date, Dec. 12, 1936. (Class 37] [Also in Groups XIII and XXXII] A damping device for oscillating elements in an oil chamber has a damping surface adjustable in accordance with temperature by one or more bimetal strips having different effective lengths or sensitivities so as to provide substantially constant damping 'by compensating for the change in viscosity of the oil. In the sound-recording oscillograph shown, two conducting tapes 9, 10 are mounted at one end 11 and form at the other end a loop engaging a hook 13 by which the tapes are strained against a bar 12. An oscillating mirror 14 is mounted on the tapes, the whole moving system being disposed in an oil chamber closed by a lens 15, which is planar on its side facing the mirror so as to serve as a fixed damping surface. The adjustable damping surface 8 is disposed on a body 7 which is fastened through a bolt 6 and nut 5 to the free end of a bimetal strip 4. A stop 3 is arranged so that the strip 4 abuts against it at a certain temperature and thereby has its effective length reduced from L to L1. The stop 3 is adjustable in two perpendicular directions as shown by the arrows I. The body 7 is relatively large and is of a material such as copper that is a good conductor of heat. The damping surface 8 is blackened to prevent reflection of light, the blackening material also having a high heat conductivity.

Surveying-apparatus.-Relates to apparatus of the kind in which a camera supported on a stand has on its upper surface a periscopic device carrying a lens adapted, as the periscope is turned, to project a continuous image of the surroundings through a radial slit in a disc moving with the periscope. The invention consists in the combination of parts described. The camera comprises a box a, adapted to be screwed to a tripod stand and levelled with the aid of levels d, and containing rollers c on which a photographic film x is stretched. Rotatably mounted above a circular aperture in the top of the box is a disc having a slit crossed by a wire n, and on the disc is supported a periscope tube l containing a lens k and prism m. The disc is rotated by springs or a weight, and during the rotation a photograph of the whole of the surrounding country is impressed on the film through the slit j, together with a circular horizon line o due to the shadow of the wire n. The edge of the disc and the top of the case are marked with the points of the compass, and are correctly oriented before the exposure with the add of a magnetic compass e. Pins s on the case cast shadows on the film to indicate the orientation on the photograph. The roll film may be replaced by a plate or film pack. The apparatus may be used in conjunction with stakes painted in horizontal bands for contouring.

Abstract: 1517965 Making waveguide ribbons WESTERN ELECTRIC CO Inc 20 Aug 1975 [30 Aug 1974] 34682/75 Heading C1M [Also in Division G2] A "ribbon" or "tape" of optical fibre waveguides is made by aligning a plurality of individual waveguides 13-1 to 13-5 in a grooved holder 11, introducing a spacer strip 14-1 to 14-4 between each pair of waveguides such that each spacer is in contact with two adjacent waveguides, and heating the arrangement to the softening point of the spacing strips, the spacing strips being of a material which fuses to the waveguides and whose softening temperature is lower than that of the waveguides. As described the process may be continuous, a roller (15, Fig. 1A, not shown) bearing on the spacers and waveguides to hold them in place as they are drawn beneath heater 16. The ribbon may be subsequently encased in plastics material. A device for severing the ribbon is shown (Fig. 3) which comprises a flexible plate 32 whose ends are held down by pivoted bridge pieces 33, 34 while the centre is bowed by screw 31. The jacket 25 of the ribbon to be severed is removed and the exposed waveguides laid under the bridges 33, 34 and over plate 32. After slight bowing of the plate a diamond 35 scratches transversely across all waveguides in the ribbon, and further bowing causes severance. Two ribbons may be joined end to end by severing the ends as described above to give "true" surfaces, and laying the ends in axial contact in a shallow trough of width just sufficient to accommodate the ribbons. A matching bonding material (e.g. an epoxy) is introduced while the ends are held flat in the trough by a cover plate. The waveguides and spacers may be of glass (exemplary compositions being given) or of plastics (e.g. polymethyl methacrylate or polystyrene).

Abstract: 1485114 Photo-electric stepping control HAWKER SIDDELEY AVIATION Ltd 30 Sept 1974 [20 July 1973] 34852/73 Heading G1A To move a workpiece repetitively through a given distance, e.g. to step an aircraft component past a riveting head, a triangular plate positioned between a light source and detector is coupled to a clutch to move with the workpiece until light from the source can reach the detector; at that moment the workpiece motion is braked, e.g. so that a rivet can be inserted, and the clutch is disengaged so that the plate returns to its initial position. The process then repeats. In Fig. 6 the plate is shown at 41; this is a view from the top of a rail mounted trolley to which the workpiece is connected, Figs. 1-4 (not shown). The plate obstructs the light path between source and detector 31a, 31b, Fig. 5, but when the trolley moves a gear 51 engaging rail 27 drives clutch 50 and hence, via gear 49 and arms 46, 44, drives the plate 41. When light strikes the detector this operates trolley brakes (not shown) and disengages the clutch, the plate being returned to its initial Fig. 6 position by springs 48. The step distance moved is controlled by adjusting the plate position along its centre line 43 using motor 36, the position and thus the step distance being indicated by a potentiometer 39 coupled to the plate.

An electric iron comprises a rotatable cam 22 for adjusting a thermostat, a control shaft 25 connected at its lower end to the cam 22 and projecting up through a hollow or tubular front handle post 5, a valve stem 20 for a water control valve 16 projecting up into the post 5, and adjusting means extending through a wall of the post 5 adjacent its upper end for rotating the control shaft 25 and for moving the valve stem 20. In one example (Fig. 1) control levers 30, 44 for the shaft 25 and stem 20 respectively project through an opening 35 in the post 5. The shaft 25 is engaged in a slot in the inner end of the lever 30 which is free to rotate through approximately 180 degrees so that the cam 22 alters the position of a thermostat adjusting arm 24. A cam arm 48 on the lever 44 is adapted to engage and depress the stem 20 against the action of a spring 42 to close the valve 16. The levers 30, 44 co-operate with dial plates 38, 49 carrying appropriate indicia and held in place by a U-shaped spring clip 53. Fig. 4 shows a modification in which the thermostat control shaft 60 is connected to a rotatable knob 61 which is held axially by a pin 66 in the side wall of the handle post 63 engaging in a groove 67 in the knob 61. The valve stem 68 is depressable by a cam arm 70 carried by a lever 69 having an operating finger 71 and an inner ring- shaped end surrounding the knob 61. In a further modification (Fig. 6, not shown) the thermostat is controlled by a rotatable knob as in Fig. 4 but the knob is also capable of axial movement to operate the water valve, a flange on the knob co-operating with ledges in the handle post to hold the knob in the two axial positions. The thermostat shaft incorporates an expansible connection to accommodate this axial movement of the knob. Specifications 628,090 and 637,458, [Group XXXVII], are referred to.
