[Class 69 (ii)] In hydraulic transmission gear consisting of two torque-converters or couplings or of the combination of a torque-converter with a coupling in which a change of speed is effected manually or automatically, a device is provided which is dependent for its operation on the ratio between the speeds of the primary and secondary shafts ; such device either gives a signal for the changing of gear, or allows the gear change to be effected. In the form shown in Fig. 1, the primary and secondary shafts 2, 8 drive shafts 1, 7 ; when the predetermined speed ratio is attained, a disc 10 carried by a nut 9 on the screwed shaft 7 and in contact with a tapered roller 5 on the shaft 1, completes an electric circuit at 11 for giving a visible or audible signal. The contact 11 is adjustable, on a guide 13. In the form shown in Fig. 2, the primary and secondary shafts act on differential gearing, and the casing 18 carries a pinion 19 ; when the predetermined speed ratio is attained, the casing 18 is stationary, and a spring 27 acts to move a gear-wheel 20 into engagement with the pinion 19, so that the movement of the lever 24 gives a signal, or the gear change is allowed to be effected manually or automatically. Specification 440,412 is referred to. The Specification as open to inspection under Sect. 91 comprises also other arrangements. As shown in Fig. 4 (Cancelled), centrifugal governors 24, 25 act on a control member ; the latter may also be operated by a spring 33 or piston 35, and the control member may consist of a slide valve coaxial with the shafts I<1>, II<1>. In a further form, centrifugal impellers 42, 43, Fig. 6 (Cancelled), force liquid to act in opposite directions on the slide valve 53, throttle valves 55, 56 being provided.

Abstract: 1303892 Roller conveyers STOHR FORDERANLAGEN SALZER GmbH 3 Aug 1970 [5 Aug 1969] 37380/70 Heading B8A An accumulating conveyer comprises rollers 12 driven by flexible elements 16a, preferably of plastics material, secured to a driven endless belt 13 supported on vertically adjustable rollers 14. When the elements 16a engage a group of rollers 12 which are prevented from rotating by a stationary conveyed article the elements brush only briefly against the rollers and additional loading on the drive motor is small. Close spacing of the elements 16a enables heavy articles to be readily set in motion and this motion is maintained by the widely spaced elements. Alternatively the elements may be evenly spaced. In Fig. 3 (not shown), although the conveyer is curved the driving belt run is rectilinear. In Fig. 4, elements 16b are in the form of loops, the-belt 13 sliding on a support 34. In place of the loops, flexible tubing may be used. A braking arrangement includes a plate 46 raisable into contact with a group of the rollers 12 and controlled by a pair of detector rollers 38, 39, sensors 42, 43 and a delay system 52. This system may include means for delaying operation and release of the brake. The control may be such as to cause spacing out of articles as they are conveyed, Fig. 6 (not shown). A number of parallel driving belts can be used and there may be rollers intermediate the belt and the conveying rollers. The conveying rollers may be extended to one side for engagement with the flexible elements.

Title: Electronic spectroanalysis computer

Filed: 1956-12-07
Abstract: 845,292. Infra-red analysis. STANDARD TELEPHONES & CABLES Ltd. Dec. 7, 1956 [Dec. 12, 1955], No. 37481/56. Class 40(3). [Also in Group XXXVI] In apparatus for the quantitative spectrographic analysis of a material, the concentration of each component present is obtained by an analytic procedure which utilizes electrical signals representing the material and component spectra determined over the whole wavelength range of interest. The spectrograph of the unknown material can be compared mathematically with a spectrograph synthesized by combining known spectra in certain concentrations, and equating the first differential of the least squared error produced in the comparison to zero. The resulting equation:- wheref = spectrum of unknown material f k  = each component spectra (f 1 , f 2 -f n ) fi = spectrum of a constituent c; = concentration coeff. of f i . can be presented as a series of simultaneous equations which can be solved for the values of the concentration coefficients. The means by which the various spectra are first recorded is indicated in Fig. 3, the amplitude driving means 301, fed by the output of the spectrometer 313, drives the cam 302, the follower 303 operates on the shutter 304 to determine the height of the narrow beam of light projected on to the photo-sensitive disc 307 which is rotated in synchronism with the spectrometer scanning system. When developed the outline of the opaque area 312 represents the recorded spectrum. The signal representing the spectrum is obtained by rotating the disc through a narrow beam of light, the required signal is produced in a photo-sensitive device illuminated by the transmitted portion of the scanning beam. In Fig. 2 signals are generated in synchronism (with respect to wavelength) representing the unknown and constituent spectra in generators 200-203, the multipliers 204-209 produce signals representing the products of each constituent with each of every constituent f k , the multipliers 210- 212 produce signals representing the product of each of every constituent f k  with the unknown material f. By means of the linear equation solver 213 the values of each concentration coefficient can be determined. In Fig. 4 a means of checking and further adjusting (if necessary) these coefficient values is indicated. Signals representing the constituent spectra are generated at 401-406 and adjusted to their respective concentrations as previously determined in the circuits 421-426. The resulting signals are added in 427 and the result subtracted in 420 from the signal generated in 419 representing the unknown spectrum, the resultant is displayed on the C.R.T. 428 which is scanned in synchronism with the rotation of the generators. When the coefficients are correct the resulting signal will be zero. Any remaining signal is processed in the correlators 429-434 to provide feedback information to further adjust the values of the concentration coefficients to produce at the C.R.T. the required no signal condition. In Fig. 5 (not shown) the complete apparatus is illustrated.

Abstract: 338,753. Stokoe, C. L. Dec, 7, 1929. Fluid - actuated valves; locking. - A self-opening or self-closing cock for alarms, controls, and the like consists of a plug a in a casing b having an inlet port m and outlet ports j, k, the port k being used when the valve is self-opening, and the port j when it is self-closing. The plug a has a pistonshaped part exposed at x to fluid pressure so that the frictional resistance to turning on the face of a shoulder c, produced by the end thrust of said fluid pressure, holds the cock against the turning moment of a weighted or spring-loaded lever h, g when placed in this position by hand. Failure of pressure fluid returns the cock to the normal position. A resilient washer e may be used to obtain the resistance to turning and to prevent leakage of fluid past the plug a or, in place of the shoulder c, the plug may be coned to fit a correspondingly shaped bore in the casing b. The weight h, in the normal or vertical position, covers an indicator v illuminated by a lamp n which is exposed when the lever g is raised to close (or open) the cock. The cock may be used to control flow of pressure fluid to an alarm whistle, in which case said flow is cut off by hand, the valve re-opening on the removal of fluid pressure from the base of the cock due to the remedying of the defect indicated by the whistle. Specification 193,183 is referred to.
