Abstract: ABSTRACT OF THE DISCLOSURE:         Machine provided with two grinding slippers, one for each rail of a railway track, connected by a lifting jack and by driving beams to its rolling frame. On each slipper are mounted four grinding units angularly displaced with respect to each other. The slippers are located in front of one another in the transverse direction of the track and are hinged on a connecting element in order to be inclined by means of a double-acting jack. The inclination of each slipper is monitored by a potentiometer connected to an indicating dial. This machine enables truing of the rail by grinding the whole profile of the rolling surface of the rails by varying the inclination of the grinding slippers at each pass.

Abstract: A B S T R A C T            A lifting device is used for live or practice ammunition, e.g. in the form of shells (10) for which the device comprises a number of gripping means. Said gripping means are made with a number of elements (2) extending from the frame (1) of the lifting device which elements form pairs of elements that can be allotted each to its shell during the lifting. The elements are rotatably supported around their longitudinal axes in the frame and at their free ends have widened sections extending in one direction. The elements are rotatable to first rotation positions where the respective pair of elements from the side can be moved over a round of ammunition. In second rotation positions for the elements the respective pair of elements encloses its shell with the aid of the widened sections and secures the shell against movement in the transversal direction. At the respective pair of elements there is also arranged a holding trough (8) which is rotatably suppported via its back section in the frame so that its parts directed towards the sections in the pair of elements in question carry out a displacing movement towards the sec-tions. Also a lifting hook (19) is included, which in one embodiment is connected with the holding troughs via a linkage system so that the rotary movements and positions of the holding troughs in relation to the sections (2d) of the elements are controlled with the aid of the own weight of the shells and the lifting device.

Abstract: ABSTRACT OF THE DISCLOSURE           A triple function image processing system incor-porating, for operation in a first COPY mode, a light/lens imaging system for imaging originals at a viewing station or platen to produce latent electrostatic images thereof on a photoconductive surface.   The electrostatic images are developed and transferred to a copy substrate material as in conventional xerographic systems.  A flying spot light beam is provided in a second WRITE mode, the flying spot beam  writing  images  on  the  photoconductive  surface  in response to image signals input thereto.  In this mode of operation, the beam impinges on the photoconductive surface at a location upstream of the developing device.  And, in a third READ mode, the beam is impinged on the photoconduc-tive surface downstream of the developing device to scan images  developed  on  the  photoconductive  surface.   The scattered light is collected and converted to image signals representative of the image scanned. In an alternate embodiment, the flying spot beam impinges on the photoreceptor at a single location upstream of the developing device for both WRITE and READ modes.  To preserve the developed image for scanning by the flying spot beam in the READ mode, the developing device and the image transfer and cleaning mechanisms are disabled until after the developed image has been scanned.

Abstract: Abstract of the Disclosure A potato patty is made from cooked or blanched shredded potatoes and a natural potato binder.  The binder is made from cooked or blanched potatoes in which the gelatinized starch naturally present in the potatoes is extensively retrograded either by holding the potatoes at a temperature of about 50°F for at least about 16 hours, or at lower temperatures for proportionately shorter holding times, or by freezing the potatoes.  The potatoes used in preparing the binder are subdivided, preferably comminuted to a fine particle size either before or after the starch is retrograded.  Between about 10 to about 50 parts of binder are mixed with about 100 parts of the potato shreds, by weight, and a potato patty is formed from the mixture, preferably in a high-speed commercial former.  Retrogradation of the amylose component of the starch naturally present in the potato binder reduces the solubility of the starch to minimize adhesiveness of the binder sufficiently that the binder can be mixed uniformly and completely with the shreds during forming without damaging the shreds.  Theis provides a cohesive potato patty that can be deep-fat fried, without separating in the fryer.  The previously retrograded amylose in the binder re-solubilizes at the moment of frying to form a thin exterior film on the patty that inhibits penetration of fat.  The fried patty can be frozen and later reheated or fried by conventional means.  When reheated in a house-hold pop-up toaster, oil drip in the toaster is minimized.

Abstract: In a known optical cable, optical fibers are loosely laid in d number of grooves formed within an elongate plastics extrusion. Typically the grooves follow a helical path with periodically reversing pitch, the helices centered on a central longitudinal axis of the cable. A primary reason for the helical lay is to prevent the fibers from becoming stressed should a bend occur in the cable. A further benefit of loose laying of fibers in a helical groove of periodically reversing pitch is that any elongation of the cable core is not immediately transmitted to the fiber supported by it. The fiber will move from its initial loose laid position both in a direction towards the inside curve of the helix and in a direction towards the base of the grooves. When it bears against the cable core over an appreciable length, the fiber will then be subjected to tensile stress. By the invention, tolerance to core elongation is increased by arranging that the grooves at any point along the core cant towards the outside curve of the helix.
