Title: Irradiation plant
IPC: G21C1/30
Filed: 1965-03-27
Abstract: Packages of material are passed to an irradiation chamber through a non-linear passage whose cross-sectional area is reduced at a number of places. The reduced parts may be of the same material as the chamber walls, i.e. concrete, or be provided by a number of masks or door (10, Fig. 2, not shown) each having a out-out to allow passage of the packages (13) on the conveyer system (12). The packages are conveyed from the loading station (7, Fig. 1 not shown) to a closed loop conveyer (3) located in the irradiation chamber (1) and which carries them around the radio-active source (2) by means of a ring conveyer, the packages being suspended from a rail (12) mounted at a gradient to the roof of the passage, and moved by a rotating motor-driven chain. A roller or belt conveyer system may be used instead. The doors (10) are hung on hinges (11) and can be opened to allow access to the passage for servicing. They are made of lead or enriched uranium and absorb about 50% of radiation incident on them. The walls, roof and floor of the passage may be fissured to increased radiation absorption efficiency (Figs. 3 and 4, not shown). With a fissured floor and roof, a roller conveyer is used and a mask or door may be in the form of a drawbridge which in its lowered position bridges the fissures in the floor.

Title: Tandem axle mechanism with locking type differential
IPC: F16H48/08
Filed: 1966-12-05
Abstract: A tandem axle assembly comprises an interaxle differential 40 which delivers power to a differential mechanism 45 of a first axle having output shafts 42, 43, and a differential mechanism 35 of a second axle having output shafts 31, 32, the differential 35 being of a full-locking or biasing type which transmits zero or less torque respectively to one output shaft thereof upon rotation relative to the other shaft thereof. The differential 45 is driven from the side gear 60 of differential 40 through gears 55 and 54, shaft 53, pinion gear 52 and ring gear 51. The differential 35 is driven from the side gear 61 of differential 40 through shafts 39 and 38, driving pinion 37 and ring gear 36. A look-out mechanism 80, 81 is associated with differential 40, and this differential is supplied with lubricant by gears 54, 55 which deliver it to a channel in the differential housing before it drains into the differential. A fulllocking differential, Fig. 4, comprises a spider 95 which rotates with ring gear 36 and is provided on opposite faces with driving clutch teeth 96 that engage teeth on two driven clutch members 97. Each member 97 is splined on a sleeve 98 to be axially slidable therealong, the sleeves 98 being in turn spliined on the shafts 31, 32. Cam teeth 105 are formed on a clutchdisengaging member 106 mounted within the spider 95, the member 106 being rotatable relative thereto but prevented from axial movement by a snap-ring 107. The cam teeth 105 engage corresponding teeth 110 on parts 111 of the members 97. The coaction between the cam teeth 105 and 110 is such that when there is relative rotation between shafts 31 and 32, a declutching action is effected of the faster rotating shaft. A pair of coiled springs 103 are provided between sleeve members 98 and spring retainers 104 to bias the teeth 105 and 110 into the clutched condition.

Patent ES-352730-A1 (ES)
Title: Method and apparatus for optically recording color picture information
IPC: H04N5/84
Filed: 1968-04-15
Abstract: Specification describes method of and apparatus for recording the contents of a colour picture on "black and white" film in such a form that the contents can be readily read out by a flying spot scanner and converted to a colour television picture. The object to be viewed is focused by lens 13, Fig. 3, on to a black and white film 14. A banded colour filter 16, Fig. 4, is placed in front of and adjacent to lens 13, and a lenticular screen 15 is placed in front of the film. The colour filter comprises red bands 18, 21, green bands 19, 22, blue band 20 and opaque bands 17, 23 and the screen 15 is formed with a plurality of juxtaposed partcylindrical lenticulations arranged parallel to the filter bands. This results in there being formed on the film 14 a repeated pattern of coloured bands 181, 191, 201, 211, 221, 1811, &c., separated by unilluminated bands 24, 241, 2411. The light intensity in red band 181, for example, depends on the red intensity of the corresponding point of the object, and the sensitivity of the film is such that for a uniform white object the intensities of the developed bands are all equal. To reproduce the object, a flying spot scanner is used, the direction of scan being at right angles to the bands. The hue of the colour is determined by the phase of the signal with respect to the pulse signals produced by bands 24, 241 &c., and the intensity by the amplitude of the signal. The pulse signals produced by scanning bands 24, 241 &c., are thus used to phase detect the signals produced by the other bands. The thus produced "chrominance" picture C, Fig. 1 on the film 14 may be formed simultaneously with and at the side of a corresponding normal "luminance" picture L, possibly by means of a beam splitting device, or the luminance and chrominance pictures may be produced in succession, Fig. 6. The apparatus of Fig. 7 is used for said successive production, wherein the lenticular screen 34 is mounted in a frame Fig. 8 (not shown) whereby it is moved into position 341 in front of the film 30 during the chrominance exposure, and to position 34 during the luminance exposure. Colour filter 35 remains in front of the lens 33 for both exposures, the colour bands being dispersed during the luminance exposure. A cam arrangement 26 causes a claw 29 to engage in a perforation in the film and move said film through one frame distance between exposures and a shutter 31 covers the film during said movement. A telephoto lens 36 may be used.

Title: Method and apparatus for detecting the faulty working of spinning units of open-end spinning machines
IPC: D01H13/26
Filed: 1977-01-14
Abstract: A method and apparatus for detecting the faulty working of spinning units of an open-end spinning machine by monitoring the faults in yarn as it is fed from the spinning machine. An electrical signal is produced by a sensor indicating faults appearing in the yarn. Another signal of predetermined frequency corresponding to the speed of delivery of the yarn from the spinning machines is generated. The electrical signal produced by the sensor is electrically multiplied by the signal of predetermined frequency for producing a differential signal. This differential signal is filtered, shaped and integrated and subsequently compared with a preset threshold value for producing a signal indicating when the occurrence of faults exceed a predetermined threshold. This signal can be used for stopping the spinning unit.

Title: Door of the self-locking type
IPC: E05C21/02
Filed: 1977-07-08
Abstract: A door is of the type wherein the weight of the door causes locking thereof against a door frame. The door frame is of the type having extending outwardly therefrom vertically spaced pairs of support hooks for supporting the door. The door includes a door element adapted to be sealed against the door frame. A pair of vertically spaced horizontally extending locking bars are carried by the door element. Each locking bar has opposite round ends adapted to rest on and be held by a respective pair of support hooks. A pair of locking support members, one each associated with a respective locking bar, are mounted for vertical sliding movement along the door element. Each locking bar is pivotally connected to the respective locking support member about a respective horizontal axis such that upon positioning the locking bars on the respective hooks, the weight of the door will cause the locking bars to pivot about the respective pivot axes in directions away from the door element. The door is thereby pressed away from the hooks and toward the door frame. An equalizer assembly is rotatably mounted on the door element and connected to both of the locking support members for equalizing the relative positions of the locking bars with respect to the hooks upon initial positioning of the locking bars on the hooks, by allowing relative movement of the locking support members along the door element in vertical directions toward or away from each other. First rollers mounted on the locking support members for rotation about axes extending parallel to the door element and second rollers mounted on the locking support members for rotation about axes perpendicular to the door element guide the vertical movement of the locking support members. Needle bearings are provided on the opposite ends of the locking bars to prevent friction between the locking bars and the hooks.
