Title: Apparatus for directing strip material from a roll
IPC: G03B1/56
Filed: 1972-01-27
Abstract: 1376371 Tape threading apparatus EASTMAN KODAK CO 27 Jan 1972 [29 Jan 1971] 3939/72 Addition to 1219412 Heading G5R [Also in Division G2] In a modification of the film/tape threading device disclosed in Specification 1,219,412 the threading roller is replaced by two variably spaced rolls 63, 64 which apply a transverse flexing force to the outermost part of the film/  tape roll 24 or 54 to strip it from its reel. As shown in Fig. 2, the rolls 63, 64 are identical frustums and are both movable on the spindle 35. During the stripping operation the reel forces the rolls 63, 64 apart against the action of springs 37, 38 until the reel is symmetrically placed with respect to the rolls i.e. when the flanges 21, 22 of the reel abut ridges 67, 68. This occurs regardless of the gauge of film/tape used. Fig. 7 shows an alternative arrangement where the rolls 63, 64 are not identical and the latter is fixed. With this arrangement the stripping action again occurs when the upper reel flange 51 abuts ridge 67.

Filed: 1936-02-11
Abstract: 466,299. Photographic developing processes. CARPMAEL, M. H. (Wolf, G.) Feb. 11, 1936, No. 4174. [Class 98 (ii)] Exposed film with emulsion on both sides of the support, such as a colour kinematographic positive, is processed by partial development of one image alone, followed by development of both images in a common developing bath. In a film to have a Prussian blue image on one side and a red-dye-mordanted image on the other, the extra development is applied to the first image. The partial development may be effected using a stronger developer giving a higher gamma value and by flotation. The separate treatment of one image may follow the common treatment of both images. The film may have more than one emulsion on one or both sides, and may be a silver dyedestruction film. The film may have identical black-and-white records copied with different light intensities on both sides. A sound record may be copied on to the appropriate side.

Filed: 1945-02-20
Abstract: 592,671. Linear - dimensiongauges. SCHMID, F. Feb. 20, 1945, No. 4299. [Class 106 (ii)] An adjustable caliper has measuring feelers 10, 11, 12 guided in conically arranged channels in a measuring head co-axial with a measuring spindle 1 and is characterised by the division of the measuring head into two parts, the dividing surface passing through the guide channels, and by the measuring feelers and guide ways being formed of quadrangular crosssection. The'spindle 1 is supported in the neck of the body of the gauge, carries a knob 5 and the measuring sleeve 3, and is provided with a precision thread 7 and a bevelled front end which engages the measuring feelers. The latter are of prismatic form and slide in grooves in the forward conical portion 8 of the measuring head which also contains a spring 15, the inner end of which is housed in a bush which rests in notches 21 in the feelers and maintains them in contact with the spindle 1. The rear portion 9 of the measuring head screws on to the neck of the body and, at its other end, is provided with a conical recess to receive the forward portion 8 and three bevelled recesses within the conical surface, each to receive one surface of a measuring feeler. Each feeler has two outer flanks which are respectively parallel and perpendicular to the longitudinal axis of the gauge. To test a bored. hole, the gauge, with the feelers retracted, is inserted into the bore and then the feelers are driven outwards by rotating the knob 5 until they fit the wall of the bore. If, as shown, the central axis of each feeler makes an angle of 40 degrees with the longitudinal axis of the gauge, the increase in diameter of the cylinder fitted by the outer flanks of the feelers is twice the longitudinal distance through which the measuring spindle 1 has moved, and the measuring sleeve 3 may be calibrated to give a direct reading of the diameter. For greater accuracy, the feelers may be arranged to make an angle of less than 45 degrees with the longitudinal axis. Furthermore, a set of exchangeable threaded feelers may be provided to test differently threaded bores. Exchangeable measuring heads with feelers for different diameter ranges may also be provided, each head being adopted to screw on to the neck of the gauge. Specification 577,722 is referred to.

Title: Improvements in control mechanism
IPC: B63H25/22
Filed: 1919-02-27
Abstract: 140,188. Brunton, J. L., and Brunton, W. P. Feb. 27, 1919. Steering.-A control mechanism for an engine or relay operating the rudder or other moving part of an aircraft comprises a Bowden wire attached to a moving part of the engine which is put into motion by the wire casing engaging a control valve or the like and is arranged so that the valve, after moving the desired amount, is brought back automatically to neutral by the wire. The casing is made up of several spring-controlled telescopic parts, the ends being attached to the main control lever and control valve. To the aircraft control lever 10 are attached the wire 11 and a casing 101 which .slides in a second tube 102 fixed to a frame 104, the spring 103 tending to extend the tube and press the lever 10 to the right. A casing 12 connects the frame 104 with a second frame 13, from which the wire 11 passes to the lever 22 which is adapted to be operated by a moving part of the engine. The telescopic case 131, 132 on the frame 13 has a second wire 15, which is enclosed in other telescopic casings terminating at 182 at a point of attachment. to the lever 14 of the engine control valve. When the lever 14 is moved bv the casings connected with the control iever 10, water is admitted to the cylinder 21 of the engine, causing the rod 211 to move and operate the control wire 212 leading to the rudder &c. The consequent movement of the lever 22 releases the tension, and the lever 14 returns to neutral. The cylinder 21 is mounted in a frame 213 maintained centrally by springs 214. If an excessive strain occurs in the control wire 212, the cylinder and the lever 20 are moved, and the latter, by its casing connexions with the lever 14. moves the main valve to relieve the strain. The hydraulic engine 21 may be replaced by an electric motor controlled by a switch operated by the lever 14.
