Abstract: 1,071,938. Packaging machines. HOLSTEIN & KAPPERT, MASCHINENFABRIK PHOENIX G.m.b.H. May 14, 1965 [May 15, 1964], No. 20527/65. Heading B8C. Apparatus for continuous re-shaping of sachet type packages to parallelepipedic form, the sachets entering the apparatus still joined as a string, comprises forming elements, initially spaced to correspond with the spacing of sachets in the string and moving in a closed path and means to separate the string into individual packages. Means to increase the distance between the forming elements after such separating to facilitate the forming operation are provided. In one embodiment, the forming elements are arranged on a continuously rotating turret, Fig. 2 (not shown), the increase in spacing being achieved by movement radially outwards of individual formers. Each former comprises a sachet side engaging section having a bottom plate 19 and side and top engaging plates 31, 32 spring biased for outward radial movement under the control of a fixed cam 14, relative to the turret 36. It comprises also a sachet and engaging section mounted on a bellcrank 37 pivoted on the turret and capable of being swung inwards from the position of Fig. 3 to overlie the other section, by a cam 40. This section has a spring-loaded head plate 47 on which are pivoted end engaging plates 48 The sachets P enter with the formers as shown in Fig. 3 and the side sections then begin to move outwards whereby toggle linkage 29 swings inwards the plates 31, 32 to square up the package section. Means 15, 16, Fig. 2 (not shown), separate the packages and the end engaging section moves to lie over the plates 32. The side sections move further outwards so that the plates 32 press on and cause retraction of the plate 47. Relatively fixed cam means 54, 55, Fig. 4 (not shown), swing in the end plates 48 forming, with the side plates 31, triangular corner flaps as follows. The plates 31 each consist of a centre portion and end portions articulated to it. These end portions 60, Fig. 5 (not shown), initially follow the increased width of the sachet towards the end seals. As the plate 47 moves outwards, however, rods 59 on arms 52 are forced inwards by relatively fixed means 53 to press the portions 60 into the plane of the centre portions. The package corners are flattened and trapped between the end portions 60 and outwardly protruding flanges 61 of the plates 48, the latter supporting means 62 to weld their layers together and render permanent the package shape. Finally the formers return to the position of Fig. 3 when at the bottom of the turret track, permitting the packages to fall on to a conveyer beneath. In another embodiment, Fig. 1 (not shown), the formers are joined in a chain by toggle linkage, the latter being constrained by a cam track to reduce and increase the former spacing as required.

Title: Process for the production of benzines from middle oils or crude benzines rich in phenols and olefines by hydrogenation
IPC: C10G65/12
Filed: 1935-07-23
Abstract: Middle oils having an end boiling-point of from 325--350 DEG  C., and containing phenols and olefines are converted into benzines by first subjecting 30--50 per cent of the crude material to treatment with hydrogenating gases at 350--450 DEG  C. in presence of catalysts having a hydrogenating but slightly splitting action, separating any benzines produced, and then subjecting the product together with the remainder of the initial material to a strongly splitting hydrogenation in contact with catalysts having a strongly hydrogenating and splitting action.  The initial oil may contain 5 per cent phenols and have an iodine number of at least 30.  A molybdenum catalyst which has already served as a strongly splitting and hydrogenating catalyst at temperatures over 350 DEG  C. is preferably employed as the catalyst for the first treatment or other catalysts are mixed with molybdenum or tungsten catalysts to weaken their splitting tendencies.  Other catalysts with slight splitting action which may be employed comprise sulphides of nickel, cobalt, iron, zinc, manganese, and sulphides and oxides of the metals of Group 6 together with substances which reduce their splitting tendencies, e.g. zinc oxide or magnesia.  The reaction time is 1--4 minutes.  The strongly splitting reaction is carried out at 350--600 DEG  C., with a partial pressure of hydrogen of 90--95 per cent.  30 per cent of a middle oil containing 8 per cent phenols and having an iodine No. of 38 is passed at 420 DEG  C. and under a hydrogen partial pressure of 180 atmos. over a catalyst comprising molybdic acid and zinc oxide.  The 30 per cent of benzine produced is separated from the remainder which together with the residual 70 per cent of the initial material is passed at 200 atmos. and 420 DEG  C., over tungsten disulphide the partial pressure of the hydrogen being 190 atmos.  A product containing 65 per cent benzines is obtained. Specification 328,618, [Class 32], is referred to.

Title: Safety device for projectiles
IPC: F42C15/22
Filed: 1959-06-18
Abstract: 875,778. Projectile fuzes. AVIMAT A. B. June 18, 1959 [June 25, 1958], No. 20989/59. Class 9(1). A safety device for a projectile fuze comprises a member 1 housing a transverse slide 7 blocking a flash passage from a primer 3 to a detonating charge 9, when the member 1 is screwed into a casing 8 containing the charge 9. The member I has a threaded neck for connection to the fuze, the primer 3 being screwed into the neck above an axial passage filled with a composition 14. The lower side of the member 1 is closed by a disc 6 with a central aperture. Balls 16, 17 placed in a passage 18, which extends obliquely to the slide engage recesses 20 to lock the slide in the obturating position. Springs 19 holding the balls in the locking position are retained in the passage 18 by a split ring 11 of spring steel, the ends of which extend into a recess 13 in the member 1. Passages 15 in the slide are midway between the ring 11 and its centre and are filled with the composition 14. On firing a projectile fitted with the device, the slide, due to inertia, presses against the disc 6 during acceleration in the gun barrel. When acceleration ceases, the centrifugal forces produced by the rotation of the projectile having caused the balls 16, 17 to move outwards, the slide 7 moves to one end of its groove bringing one passage 15 into alignment with the primer 3. One of the weights 23 housed in the slide enters a recess 24 in the member 1 to prevent the slide returning to the safety position. The member 1 and casing 8 may be of light-weight metal such as aluminium alloy and the disc 6 and slide 7 may be of steel or iron.

Title: Improvements in or relating to loading units for machine tools
Inventor: WILLIAMSON DAVID THEODORE NELS
IPC: B23Q3/157
Filed: 1967-05-05
Abstract: 1,223,103. Workpiece and tool transferring. MOLINS MACHINE CO. Ltd. 3 May, 1968 [5 May, 1967], No. 21104/67. Heading B3B. A loading unit 148 for supplying workpieces 409 on pallets 408 and tool magazines 448 to a multi-spindle or single spindle machine tool comprises a rotatable support unit 401 for presenting the pallets 408 sequentially to a loading station and a further rotatable support unit 402 for presenting the tool magazines sequentially to the loading station. The loading station is placed between the two support units, each of which comprises paddle arms 404-407 and 442-446 on which the pallets 408 or tool magazines 448 are mounted. The pallets or magazines are moved from the loading station into the machine tool by means of a pusher beam 501 driven longitudinally to pick up a pallet and/or a magazine and transport it laterally from the loading unit. The pallets, which for a double spindle machine tool may be linked together in pairs, and the magazines have magnetic and non-magnetic plugs arranged in a sequence along their edges which enable each one to be identified by a reader head 418 and a signal to be fed to a computer and a function control device. Each paddle arm 404-407 and 442-446 has a striker for operating an individual switch 426-429 and 459-463 to enable the position of each arm to be known by the computer. Pallets 408 are fed to the support unit 401 at the right-hand horizontal position as shown in Fig. 1, where the finished machined workpieces and their pallets are also removed. The pallets are rotated in 270 degree stages, in steps of 90 degrees, during which a machine workpiece is air-blown and brushed clean by facilities 435, 437, 436 and 440. Swarf is removed by a helical screw device 439. The beam 501 can be displaced laterally so that in one position it can move pallets into the machine tool by arm engaging with the pallets, the beam can then be displaced so that it can be returned without bringing out the pallet, and can then be further displaced to pick up a tool magazine and push it into the machine tool. A pallet and tool magazine may be moved into the machine tool simultaneously. When a single spindle machine tool is used the loading unit may include means for advancing the first of a pair of linked pallets into the machine tool, lowering the second pallet to unlink them, and then allowing the machine tool to operate on the single pallet whilst the second one is indexed round with the pallet support unit 401. The machined pallet is then returned to an empty paddle of the support unit, the second pallet pushed into the machine tool for machining and then returned to the paddle of the support unit to be re-linked with the first pallet.

Title: Improved process for the preparation of spinnable solutions
IPC: C08J9/24
Filed: 1965-05-19
Abstract: Spinnable solutions of polyacrylonitrile, or of copolymers containing over 85% by weight of acrylonitrile, are produced by polymerization of the monomer(s) in dimethyl formamide in at least two sequential stages, in the first of which the polymerization is carried out at 60 DEG  to 65 DEG  C. until reaching not less than 30% and not more than 40% conversion of the monomer(s), while in the second stage or the following stages the polymerization is carried on under controlled temperature conditions until reaching a higher conversion, the amount of dimethyl formamide and catalyst required to attain said higher conversion being divided into as many fractions as there are stages and one of said fractions being individually added at the beginning of each stage.  The final conversion attained is desirably in the range 70 to 80%.  The temperature conditions may be controlled by carrying out the process under sub-atmospheric pressure, in which case the polymerization is terminated by increasing the pressure and distilling off unreacted monomer(s).  In the examples, the polymerization is carried out in two stages.  In Examples 1 and 3 copolymers of acrylonitrile, sodium allyl sulphonate and methyl methacrylate are prepared and in Example 2 a copolymer of acrylonitrile, sodium allyl sulphonate and ethyl acrylate. Lauroyl peroxide is used as catalyst and thiourea dioxide is present in the reaction solutions of Examples 1 and 2.
