Title: Machine for the separation of the tissue part from the juices or oils of vegetal products
IPC: D01B1/10
Filed: 1952-02-26
Abstract: 727,030. Treating fodder. P.A.S.T. PRODOTTI ALIMENTARI SISTEMA TALLARICO. Feb. 26, 1952 [Feb. 26, 1951 ; Dec. 15, 1951], No. 5003/52. Class 5 (2). [Also in Groups II and VI] A machine for separating tissue from juices of vegetal products such as fodder, vegetables and fruits comprises two grooved and parallel disintegrating cylinders 44 which rotate in opposite directions and at different speeds under a hopper 26, two pressing worms 9, axially separated by a distance less than the sum of their radii, contained in a slotted casing 11 enclosed in an outer cover 25, and two oppositely moving rakes 70 which disaggregate compressed tissue coming from the worms. The worms do not extend to the end of the cover but leave a compression chamber closed by a shutter 23 loaded by a spring 16 the pressure of which may be varied by a screw 21 or by changing the spring. The pitch of each worm may decrease and the diameter of its shaft 51 may increase in the direction of propulsion of tissue. The casing may comprise two major segments of a cylinder connected along their longitudinal edges and may be reinforced by steel rings between which cocoafibre strainers may be fitted. The cover has a juice outlet 12 leading into a sump 10. Each rake may be in the form of a shaft having teeth lying substantially in one plane. The two rakes may be rocked alternately upwards and downwards so that the teeth of one pass between those of the other. To facilitate treatment of fodders having large stems, two oppositely rotating, star-sectioned breaking rollers may be removably mounted in the hopper above the disintegrating cylinders. To facilitate treatment of olives, a grate may be provided in the hopper over the disintegrating cylinders together with a shaft carrying helically arranged teeth which pass between the bars of the grate when the shaft is rotated. Vegetal products may be fed into the hopper by a belt conveyer.

Title: Improvements in or relating to governors for operating regulators safety devices, closure members and the like
IPC: G05D13/00
Filed: 1933-02-18
Abstract: 411,979. Pneumatic single - stroke apparatus. SEIFFERT & CO. AKT.-GES., F., 13, Oberwasserstrasse, and MEYER, C., 2, Xantenerstrasse, both in Berlin. Feb. 18, 1933, No. 5028. [Class 8 (ii).] A device for controlling the movement of regulators, safety devices, closure members, such as isolating valves, and the like compri ses a controlling body such as a vane 3, Fig. 1, or a piston or diaphragm the opposite sides of which are subject to different fluid pressures to produce movement or cause release for movement of the regulator or the like, the controlling body being counter-loaded by adjustable resistances which delay its movement until one or both of the said resistances are released from it upon the attainment of a predetermined pressure difference. The vane 3 is mounted on a shaft 2 in a cylindrical casing 1, the fluid having access to the casing on opposite sides of the vane. The ends of a lever 13 fixed to the shaft contact levers 16, 17, Fig. 3, having adjustable weights 14, 15 or springs. The levers 16, 17, in the centre position of the vane, contact adjustable stop-members 18, 19 which may be arranged so that a small movement of the lever 13 in either direction is necessary before the load takes effect. The shaft 2 may, on release of the lever 13, after a certain angular movement operate the regulator or the like directly. For instance, it may turn a plug cock. As shown in Fig. 1, however, it releases by the rotation of a projection 6, a catch wheel 8, the spindle of which is directly or indirectly connected to the regulator or the like. The weight 9 then ensures the operation of the regulator. Several vanes working in the same or different casings may be arranged on the shaft 2. In a modification having a piston working in a cylinder, the ends of the piston rod abut the short arms of bell-crank levers loaded by weights or springs. On the attainment of the predetermined pressure difference, one end of the piston rod is moved out of the path of the bell crank opposing its motion and the motion of the piston rod is transmitted directly or indirectly to the regulator or the like. In this form also, the bell crank levers have adjustable stops which may be arranged to permit a slight free movement to the piston in its middle position.

Title: Improvements in cam gears for internal combustion engines
IPC: F01B9/06
Filed: 1931-02-19
Abstract: 375,365. Driving-gear. KREIDLER, A., 1, Gansheidestrasse, Stuttgart, Germany. Feb. 19, 1931, No. 5287. Convention date, March 17, 1930. [Class 7 (ii).] The piston of an internal combustion engine is provided with rollers a fixed axial distance apart which engage two cam tracks formed on a cam disc and at the places where the cam track facing the piston is very steep the cam track facing away from the piston is less steep so that the outer guiding roller is just out of contact with the cam surface at these places during normal running, but in the event of a missfire the outer roller engages the track to pull the piston out of the cylinder. In a modified construction, which is shown in Figs. 1 and 4, the roller 8 running on the cam track 5 facing away from the piston 1 is connected to the piston by a spring 9 so that the rollers 4, 8 remain always in contact with the cam surfaces 3, 5.

Title: Regenerative air preheater with automatically adjustable sealing device
IPC: F24H7/02
Filed: 1973-02-05
Abstract: 1412872 Thermal regenerators APPARATEBAU ROTHEMUHLE BRANDT & KRITZLER 5 Feb 1973 [8 Feb 1972] 5492/73 Heading F4K In a rotary duct type regenerative air preheater incorporating sealing elements in the form of frames 7 and 8 located between the respective rotating air hoods 4 and 5 and the hot and cold faces 2 and 3 of the regenerator mass 1, the sealing elements are automatically adjustable by temperature responsive devices 18, 19 which are arranged to cause stops 21 for the sealing elements to move in a given axial direction upon an increase in temperature and in the opposite direction upon a decrease in temperature. Each temperature responsive device 18 is in the form of a thermal expansion device comprising expansion rods (33, Fig. 2) on either side of a central rod 29 whose coeff. of expansion is greater than that of the side rods (33). The rods extend between a cross piece 30 and a plate 35. The movable stop, which is in the form of a curved fork 21 mounted on a spring pin 13 carrying lock nuts 20, is fixed between twin lever plates 22 journalled on a shaft 23 in a bracket 24 secured to the surface of the upper hood 4. The lever plates 22 have apertures 25 to which an extension of the rod 29 is secured via a pivot pin 26. A rise in temperature causes expansion of rod 29 which in turn causes the levers 22 to rotate anticlockwise with consequential lowering of the stop 21; this permits lowering of the pins 13 and hence movement of the sealing frame 7 towards the hot face of the regenerator mass. Similar expansion devices 19 and lever linkages are provided at the cold end, the expansion coefficient of rod 29 in this case being less than that of the side rods (33).  The thermal expansion device 19 at the cold end is surrounded by a thermally insulated jacket 40 which is fed with gas at a controlled temperature through ducts 41 and 43 by means of a fan 42. The temperature of this gas is preferably made equal to the mean temperature difference between the two heat exchanging gases passing through the regenerator mass. A rotable connection 44 is provided between the moving duct 41 and stationary duct 43. In an alternative embodiment (Fig. 5, not shown) the device 19 is surrounded by gas fed from the hot end of the regenerator mass by way of a duct (45) which rotates with the hoods. In a further embodiment (Fig. 6, not shown) the gas surrounding the device 19 comprises a mixture of incoming hot gas and ambient air. The invention may also be applied to regenerators of the rotary mass type.

Abstract: 1,077,561. Inspecting webs photo-electrically. TATEISI ELECTRONICS CO. Feb. 9, 1965 [Feb.18, 1964; Feb.19, 1964(2); Oct.7, 1964(2)], No.5559/65. Heading G1A. Defects in a moving web are detected by measuring variations in the amount of light transmitted by the web and marked by a device which blows solid or liquid coloured material on to the web at a defect. The transmitted light intensity is measured by photo-sensitive means feeding an A. C. amplifier. The output of the amplifier may be fed to a phase splitter and when either of the signals produced thereby trips a schmidt trigger a corresponding colour is sprayed on to the web by actuation of an appropriate electromagnetic valve. Holes and thin parts of the web are thus distinguished from stains by the colour of the marking. A monostable multi-vibrator may be necessary to stretch the pulses from the A. C. amplifier sufficiently to operate the electromagnetic valve. The light source is preferably a fluorescent tube extending across the whole width of the web and the photo-sensitive means a corresponding row of photo-voltaic cells. Each cell is connected to its own A. C. amplifier and trigger circuit, the latter being connected to an "OR" gate the output of which operates the marker. To prevent light reaching the end cells directly, screens are provided of sufficient size to cover the edges of the web at all times. The parts of the web which have passed over these screens and so not been inspected are cut off. A further screen extending across the web may be provided to reduce the field of view of the cells when small defects are to be detected.
