Patent GB-133512-A (GB)
IPC: E21C49/00
Abstract: 133,512. Shuttleworth, J. M. Nov. 13, 1918. Peat, preparing.-A single travelling apparatus is used for excavating peat, spreading it for drying, and gathering and piling the dry peat for loading. A platform 11 mounted on endless travelling-tracks 12 is provided with any suitable type of excavator 13 and a macerator 14 which receives the excavated peat. The endless travelling tracks preferably have independent driving- means and reversing-gears. Electric driving- means may be used, or steam - engines arranged on the platform together with a steam-boiler 15. A bridge 16 is hinged at one end to the platform and supported at the other end on an endless travelling-track 17, driven by the same motion power as the platform endless track, but independently. An endless-belt conveyer 18 on the bridge is preferably driven from the macerator. An elevator 19, preferably driven from the conveyer, is provided at the end of the bridge. A peat spreader 20 is attached to the bridge so as to be movable along it as desired. An unloader 21 for the conveyer is mounted adjustably on the bridge. When the apparatus is in operation, the pulped peat passes from the macerator 14 to the conveyer 18, which carries it to the spreader 20. This deposits the peat in a form resembling bricks placed end to end. The apparatus travels along the peat face, which may be several miles long, and is reversed at the end of each traverse, so that the apparatus makes cut after cut in the peat and continues to advance and layout the peat to dry on the drying-ground swept by the conveyer. When the first-laid peat is dry, it is. piled in heaps by operatives lying in convenient positions on the bridge or on a platform suspended below, and later the dry peat is fed by other operatives into a hopper 22 and falls on to the conveyer which feeds an elevator arranged to stack the peat at the maximum distance possible from the bridge. In this way, the operations of cutting, drying, and gathering proceed simultaneously over ground which serves as a drying floor and is being gradually sliced away on the excavator side of the apparatus and simultaneously extended as a drying ground on the opposite side.

Title: Improvements in change speed mechanism
IPC: F16H61/02
Filed: 1919-05-27
Abstract: 143,718. Farley, J. May 27, 1919. Variable-speed and reversing epicyclic gearing comprises alined driving and driven shafts 1, 2, the latter having a carrier-disk 8 supporting a toothed wheel 11 meshing with a pinion 6 secured to the former. Stepped planet gears 12, 13, 14 rotatively secured to the wheel 11 mesh constantly with toothed rings 15, 16, 17 loose upon a fixed member 18. Three forward speeds are imparted to the shaft 2 by fixing the rings 15, &c. alternatively to the member 18. For this purpose, keys such as 27 are provided sliding in radial grooves in the member 18. These keys are set severally in the planes of the rings and in different angular positions, so that they can be operated by separate sliding rods such as 26 and separate levers such as 29. The key 27 is thrust outwards to engage a keyway in the ring 17 when the rod 26 is pulled outwards by means of a pin 32, Fig. 5, on the rod engaging a slot 31 in the key. The fixing-means for the loose rings may alternatively consist of rods or keys of D-section which can be turned on their axes to engage or to free the rings. Reversed driving is effected by sliding an internally toothed ring 34 upon a feather on the member 18 into mesh with the gear 14. If the shaft 2 is clutched to the shaft 1, it is driven in the same direction as the reversed drive described. Chain, belt, or friction gearing may be used. The invention is applicable for driving lathes or motor-vehicles.

Title: Improvements in television transmitters
IPC: H04N5/228
Filed: 1939-05-04
Abstract: 528,355. Television. PHILIPS LAMPS, Ltd. May 4, 1939, No. 13402. Convention date, May 7, 1938. [Class 40 (iii)] Relates to television transmitters in which the photo-electric screen of a cathode-ray tube is alternately exposed to a picture film and scanned by the cathode ray as described in Specification 431,207. According to the invention the period of time during which the screen is exposed to the picture is made longer than the time interval between two successive scannings, this increased time of exposure giving a higher charge to the screen and therefore a larger amplitude to the picture currents. The transition impulses are compensated in known manner by a photo-electric cell illuminated directly or indirectly by the light which strikes the screen of the cathode-ray tube. If an increase in the picture currents tends to occur during the times when scanning and exposure coincide, compensation may be made by modulating the picture currents by the compensating impulse of the aforesaid photo-electric cell.

Abstract: 928,946. Measuring electrically. BENDIX CORPORATION. April 14, 1961 [April 15, 1960], No. 13455/61. Drawings to Specification. Class 40 (1). [Also in Group XIX] Apparatus for computing a variable aerodynamic factor (e.g. airspeed, altitude, vertical speed) based on an erroneous static pressure measurement, comprises means for producing a first magnitude representing the factor as derived from the erroneous measurement, means for computing the Mach number and computing from it a second magnitude representing the error in the factor due to the erroneous measurement at the current Mach number, and means for combining the two magnitudes to give a third magnitude representing the corrected value of the factor. The variation of the error with Mach number is predetermined for the particular aircraft. The three magnitudes may be shaft rotations or electric signals. Mechanical systems (see Group XIX) employing two- or three-dimensional cams to apply the correction are described for measuring altitude and airspeed. Vertical speed is determined by measuring the rate of rotation of the altimeter output shaft using a rate generator. An electromechanical system employing synchro-type or potentiometric signal generators is also referred to. Specifications 774,341 and 774,639 are referred to.
