Abstract: 567,401. Linear - dimension gauges. KAPELLA, Ltd., and COOKE, E. A. May 13, 1943, No. 7666. [Class 106 (ii)] A linear dimension gauge comprises two gauging elements D, E carried by a common main supporting bar D' mounted on parallel spring ligaments F<9> so arranged that the bar, though movable in the general direction of its length, always remains parallel to itself, one gauging element D being normally fixed with respect to the main supporting bar whereas the other E is yieldingly carried thereby, an electromagnetic device being provided for controlling indicating or recording means, the device having two relatively-movable parts actuated by relative movements of the gauging elements. The main bar D' has end brackets F<7>, F<8> supported by spring filaments F<9> from projections C<6> on a carriage C adjustable vertically on a screw-threaded shaft C<4> by an external handle. The gauging element D is adjustable along the main bar D' and is locked thereto by a bolt D<9>. In the construction shown in Fig. 2, a second bar E<4> is supported from the end brackets of the main bar by spring filaments E<5>, and carries near each end a pillar H<8> supporting through a spring filament H<9> an adaptor E', opposed by a vertical bar H<10>. One of the adaptors holds the second gauging, element E which is adjusted finely by the co-operation of the bar H<10> with a screw J<3> controlled by a hand wheel J<5>. The bars D<7> and E<4> are urged in opposite directions by a spring K<2>. The bar E<4> carries two coils L<1>, L<2> in one or other of the circuits described in Specification 541,627, [Group XXXVIII], the reluctance of which is affected by movement of an armature M carried by the bar D<7> As shown, the apparatus is arranged for internal measurements, but the element D may be turned round and moved along the main bar, and the element E may be turned round and secured to the alternative adapter E<7>. In the modification shown in Fig. 10, the adaptors are secured to the pillars H<8> by spring filaments S<3>, S<4> arranged at right angles. The coils L<1>, L<2> are carried by the bar D' and a ball M<4> on the armature M<5> projects so as to bear against one or other of two blocks G<6> on the bar E<4>. In a further modification, Fig. 7, the bar E<4> is dispensed with. A unit Q is adjustable along the main bar P<1> and is secured thereto by bolts P<3>. Slidable in guides of the unit is a casing W carrying the electromagnetic device and the element E mounted on a spring filament W'. The casing W is adjusted along the guides by a nut Q<6> co-operating with a screw Q<5> and a flange Q<3> or by the knurled screw Q<4>, according to whether the casing is more easily accessible from the left or the right of the outer casing. The armature M<5> of the coils L', L<2> is secured to the element E and is adjustable through a spring M<3> by a stud M<2>. In a slight modification, the element E may be pivoted to the bottom of the casing W and may constitute the armature M<5>.
Patent GB-378849-A (GB)
Title: Process of producing chlorinated diaryl resins
IPC: C08F8/20
Filed: 1931-03-12
Abstract: Light coloured resins are obtained by the fractional distillation of the products prepared according to the processes of Specifications 358,703 and 358,704.  In the commercial production of diphenyl by the pyrolysis of benzene vapour at 850 DEG  C., products are obtained which can be separated, after removal of unchanged benzene, into three fractions by distillation: (1) that boiling between 250-270 DEG C. comprising mainly diphenyl, (2) the fraction boiling from 270 DEG C. up to 400 DEG  or 420 DEG  C. consisting of diaryls related to diphenyl, and (3) the residue known as "still bottoms" comprising more complex compounds than those of the second fraction.  Examples are given of the chlorination of the first fraction alone or of mixtures thereof with the second and third fractions, preferably until the product contains over 60 per cent chlorine, followed by distillation of the products, at atmospheric or under reduced pressure, until a certain proportion has come over.  The chlorination is effected in iron vessels, using iron as the catalyst, but other chlorination catalysts such as aluminium chloride, sulphur chloride and antimony pentachloride may be employed.  The chlorinated product prior to distillation is a dark coloured oil or resin, whose specific gravity, viscosity or softening point, and chlorine content is determined; the same physical characteristics of the product after distillation are also stated.  Curves are given which show the relationship between the softening point and the percentage distilled over for various chlorinated products, from which a certain degree of regulation of the process is possible.

Abstract: 439,864. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. March 10, 1934, No. 7719. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 1, 1935]. [Class 40 (iv)] A junction is tested as regards its continuity and the condition of the apparatus at the incoming end by an alternating-current test circuit extending over the junction. When the group selector GV reaches the junction FL shown, a high-resistance relay R2 energizes in the ordinary test circuit and completes a local A.C. circuit for relay VR1 through the left-hand windings of transformer TR1 and filter C1, C2. If no fault exists on the junction and the normal contacts K1 of the incoming selector are closed, sufficient current flows to operate relay VR1 which substitutes relay R3 for R2 and permits R1 to operate. The pulse of A.C. transmitted over the junction operates LR which through R6 prepares the incoming selector and locks up R7. Subsequent digits are repeated over the junction in the form of A.C. impulses by relay R5 and at the end of the call a prolonged pulse of A.C. operates relay R8 to unlock R7.

Title: Thienamycin recovery
IPC: C07D477/02
Filed: 1978-02-27
Abstract: A thienamycin-containing fermentation broth or solution is brought into contact with a liquid ion exchanger which is dissolved in an organic solvent and is insoluble in water. In this process, the antibiotic is transferred, by forward extraction, into the liquid ion exchanger system. The liquid ion exchanger system, containing the antibiotic, is then brought into contact with an aqueous buffer. During this process, the antibiotic is transferred, by back extraction, into the aqueous buffer phase. The process is simple to carry out and the antibiotic thienamycin accrues, as the end product, in high yield and in pure form. Thienamycin exhibits antibiotic activity against Gram-negative and Gram-positive microorganisms.

Filed: 1937-03-17
Abstract: 491,900. Actuation of switches; indicating leaks in cables. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and ARMAN, A. N. March 17, 1937, No. 7883. [Class 38 (v)] [Also in Group XXVIII] When gas pressure rises in an enclosure 1, bellows 4 are compressed causing plate 8 to rise and cause link 23 to snap over a spring toggle 15, 16 to cose contacts 18, 20. The over travel of toggle link 16 moves link 23 upwards to open a valve 10 allowing the excess gas to pass to the atmosphere through a tube 7. This allows the bellows to expand and open the switch and close the valve 10. The device is described as applied to indicating leakage into an enclosure for a gasfilled cable, when the frequency of operation of the switch as shown on a recording galvanometer shows the magnitude of the leak. Fig. 3 shows an indicating system for three single core cables A, B, C of a three-phase system, in which the enclosures are divided into lengths each provided with a pressure operated switch 36 adapted on operation to ground the corresponding pilot wire a, b or c. This energizes the corresponding relay 24 to give an indication on a three colour thread recording galvanometer G. Thus the magnitude frequency and colour of the indications serve to show respectively the location and magnitude of the leak and in which cable it is present.
