Title: A process for the production of lactams of ªÏ-amino-dodecanoic acids having two unsaturated double bonds
IPC: C08G69/14
Filed: 1960-07-15
Abstract: The invention comprises the lactams of 12-amino -5,9-diene-dodecanoic acid and of 12-amino -4,8-dienedodecanoic acid, and their preparation by subjecting an oxime of a cyclododeca -4,8-diene -1- one to rearrangement in the presence of an acid chloride.  The preferred acid chloride is thionyl chloride used as a solution in sulphur dioxide.  The two carbon to carbon double bonds in the oxime starting material may both be of trans configuration or, alternatively, one may be cis and the other trans. The above lactams can be used to form corresponding unsaturated polyamides.  The oxine of cyclododeca -4,8-diene- -1- one is obtained by treating the corresponding ketone with hydroxylamine hydrochloride.   Cyclododeca -4,8-diene -1- one is by treating cyclododecadiene epoxide with ethereal magnesium iodide.  Specifications 848,951, 849,236, 849,238 and 876,531 are referred to.ALSO:The lactams of 12-amino-5,9- -diene-dodecanoic acid and of 12-amino- 4,8-diene-dodecanoic acid are used to form unsaturated polyamides.

Abstract: 1,014,367. Roller and reciprocating conveyers. VITRO CORPORATION OF AMERICA. June 18, 1964 [June 19, 1963], No. 25301/64. Heading B8A. [Also in Division H5] In a mobile irradiation unit 10, for the irradiation of packages 16 of e.g. foodstuffs &c., by e.g. γ-rays, the packages are conveyed inside a shielding shell 17 and along a predetermined track around a slab-shaped source 27. The irradiation procedure commences with the passages around the slab source being occupied by empty containers 16<SP>1</SP>, these having been passed through the unit in the previous operation to remove the last of the filled containers. A filled container 16 is first moved from roller conveyer 14 into the loading breech 18 by hydraulic pusher 52 and is loaded inside the shielding from the loading breech slide 18 by hydraulic means 20, afterwards being pushed from the slide 18 into the location A on a transversely movable shuttle platform 38, by means of an hydraulically-operated pusher 36. The container 16 can then be moved on roller conveyers, or perforated metal slides, throughout the irradiation passageway system, followed by other containers 16, by a sequence of successive operations of hydraulic pushers 36, 43 and 48 and movement of shuttle platforms 38 and 45, containers being unloaded, after irradiation, by breech slide 19 on to roller conveyer 15. Initially, empty containers are unloaded, but later full containers emerge after having undergone full irradiation treatment by travelling along a path consisting of row F to shuttle 45, back along row G to shuttle 38, along row H and back along row J. The dose to which the containers are subjected may be controlled by adjustment of the sequence control timer. In a modification, pusher 35 may be eliminated by use of a wider shuttle platform 38.

IPC: H01P1/18
Filed: 1959-07-23
Abstract: 888,901. High frequency bridge networks. GENERAL ELECTRIC CO. Ltd. July 19, 1960 [July 23, 1959], No. 25313/59. Class 40(8). A four-terminal phase equaliser network comprises a first lower length of transmission line extending between a pair of input connectors 2 and a pair of output connectors 3, a second upper length of transmission line extending between the pairs of connectors, the first and second lengths of line being connected in parallel between the pairs of connectors, a third length 4 of transmission line connected to the second line as a stub, and lumped impedance elements connected across each of the first and third lines and each part of the second line on either side of the junction with the third line 4, the arrangement being such that the network is equivalent to a bridged-T network formed of lumped impedance elements. The lengths of transmission lines can be all coaxial lines, the first and second lengths being formed by a ring 1 or other configuration of coaxial line. Waveguides or strip lines can be used instead of coaxial lines. The lumped impedance element connected across the first length of line can be a screw 11 forming a lumped capacity, those connected across the second length can be waves 12 forming lumped inductances, and those connected across the third length 4 can be a wire 18 forming a lumped inductance and a screw 19 forming a lumped capacity. The third stub line 4 has a length approximately equal to three-quarters of a wavelength at the operating frequency and the wire 18 is located a quarter wavelength from the second of line. The position of the screw 19 is adusted so that at the operating frequency it provides in conjunction with the short circuit at the end 17 of the stub 4 an effective capacity across the inductance provided by the wire 18 so as to form a parallel resonant circuit. The coaxial ring 1 comprising the first and second lengths of transmission line has a length of one and a half wavelengths at the operating frequency and the elements 2, 11, 3, 12, 4, 12 are equally spaced therearound. The outer conductor of the coaxial line 1 is formed by two metal plates 5 and 6 held together by screws 7, the opposing faces of the plates having an annular recess of semi-circular cross-section, and the inner conductor 8 is supported by discs 9 of polyethylene. In modifications different parts of the ring 1 can have different values of characteristic impedance, the capacity formed by the screw 11 can be replaced by an inductance and the inductances formed by the wires 12 can be replaced by capacities.

Abstract: 1509528 Radiographic apparatus EMI Ltd 23 May 1975 [7 June 1974] 25361/74 Heading H4F Radiological apparatus comprises a source 19 (of X or gamma rays) for irradiating a body 3 along a plurality of coplanar paths, detector means 25 for detecting the amount of radiation emergence along each path and emitting a signal indicative thereof, attenuator means 11, 12 which substantially equalize the absorption of radiation along different paths, the material of the attenuators being such (e.g. Al, B, Cu) as to shift the radiation spectrum by an amount dependent on the thickness of attenuator in each path, and means to operate on the output signals to compensate for variations in the amount of detected radiation due to the change in the spectrum. As described, body 3 is surrounded by a water sack 10 and held in frame 8 1 , 8 2 . The source 19, which produces a pencil beam or a fan-shaped swath, is mounted on belt 16 driven by motor 15 and is coupled through arm 24 to drive detector 25 in synchronism. After each run of the source along the track, disc 1 (on which everything but the clamped body is mounted) is rotated by motor 5 and drive wheel 6 through an angle corresponding to the angle of the swath 20, i.e. 10 degrees until the body has been scanned through over 180 degrees. Counterweight 22 is provided on belt 16 to counteract the effect of the mass of source 19. The output from the detector is operated on by the circuit of Fig. 3 wherein stores 36r, 40r, contain path variation a r  and differential hardness b r  weighting factors respectively-the latter compensating for the change in spectrum due to the material of the attenuators. These factors may respectively be determined empirically by scanning firstly with hole 2 filled with water and secondly by replacing body 3 with a bar of known size of the attenuating material. Alternatively the absorption factors may be determined mathematically assuming a knowledge of the absorption factors of the materials involved, including the nature of body 3.

Abstract: 1330381 Packaging flattened bags WINDMOLLER & HOLSCHER 19 April 1971 [17 April 1970] 25873/71 Heading B8C Stacks 2 of flattened bags from a bag making machine A are orientated by parcelling apparatus D so that in a parcel to be packaged by apparatus C, the bottoms of the bags in adjacent stacks point in opposite directions. The packages 3 are thus parallelepipedal. Grippers G carry the stacks 2 from the machine A to the parcelling apparatus D where they arrive bottom first. Successive stacks are turned sideways through 90 degrees in alternately opposite directions and deposited on a table 5 by the mechanism shown in Fig. 2. Each stack 2 is initially gripped between a rotatable plate 9, which is fixed relative to a slide 7, and a rotatable plate 11 mounted on a frame 10 which is pivoted relative to the slide 7. After the stack 2 is gripped, the slide 7 is moved downwardly on guide rods 6, 6<SP>1</SP> so that a fixed rack 22 acting through a toothed wheel 17 and connecting rod 18 rotates the plate 11, and thus the stack 2, through 90 degrees. Successive downward movements of the slide 7 oscillate the plate 11 through 90 degrees. The wheel 17 includes a freewheel device so that upward movements of the slide 7 do not move the plate 11. The transfer of each stack 2 to the table 5 is completed by a gripper which slides on rods 26, 26<SP>1</SP> and whose jaws 23, 24 are operated by the co-operation of a roller 29 with a fixed rail 30 and a movable rail 30<SP>1</SP>, the latter opening the jaws near the top of their upward travel and closing them at the top of their upward travel. Each stack 2 deposited on the table 5 is transferred by a pusher 33 to a parcelling station 36 where the stacks are retained by brushes 37, fingers 38 and springs 56. The arrival of each stack is signalled to a counter 45 by a photoelectric senser 46, 461. When a predetermined number of stacks has been counted, a programmer 44 actuates a pusher 39 to move the completed parcel to the wrapping apparatus C. The table 5 is formed by parallel bars, and the pushers 33 and 39 and gripper jaws 23 and 24 are in the form of fingers which can move between the bars. To accommodate different bag sizes, the parcelling apparatus D is movable along a track 57 by a screw 58. Each stack may be stapled at 55 prior to parcelling.
