Title: Improvements in or relating to photographic roll films
IPC: G03C3/02
Filed: 1934-03-23
Abstract: 435,467. Roll films. KODAK, Ltd., Kingsway, London.-(Eastman Kodak Co.; 343, State Street, Rochester, New York, U.S.A.) March 23, 1934, No. 9102. [Class 98 (i)] A roll film of the kind comprising a sensitive strip 45 having openings 47 longitudinally spaced apart at intervals corresponding to the length of an exposure area and a backing strip 51 for the sensitive strip, has the part of the backing strip lying between the leading end of the sensitive strip and the first opening therein folded transversely to give a Z-shaped view from the longitudinal edge and a slot or slit 55 formed in the angle 54 of the inner fold lying adjacent to the sensitive strip. The backing strip is prevented from unfolding by an adhesive seal 56 that secures the upper fold 53 to the leading end of the backing strip, the part of the strip corresponding to the slot 55 being left uncovered. The film is engaged by a feeler member 18 as described in Specification 435,468 and is moved as stated in that Specification. The backing strip 51 of the film is provided with a slot 55 in the angle of its Z-fold adjacent to the apertures 47 in the strip 45. When the film has been inserted and the back placed in position the winding key is rotated and as the film passes towards the take-up chamber a rib on the film guide bends the material into the plane of the separating finger 40 so that this finger readily passes through the slot 55 and enters between the sensitive and backing strips : continued movement of the film thus causes the backing strip to be raised from the sensitive strip in the vicinity of the finger so that when the first perforation 47 in the sensitive film comes into register with the feeler member 18 this member passes therethrough and simultaneously a member locks the winding device. After the exposure has been made the winding device is freed and the member 18 depressed by a release stud. The rib on the film guide may be omitted.

Filed: 1969-02-20
Abstract: 1,262,747. Measuring ground pore water pressure. STICHTING WATERBOUWKUNDIG LABORATORIUM. Feb.20,1969 [Feb.23, 1968], No.9163/69. Headings G1N and G1S. The pressure of ground water in the pores of cohering soil is measured by a tubular probe inserted into the ground and containing a bellows 3 responsive to the ground water pressure to position a magnetically permeable core 8 of a differential transformer. The lower end of the probe has a porous filter element 2 with a protective metal cap 16. The bellows is surrounded by oil which is separated from the ground water by a resilient foil or bag 17. Excessive displacement of the bellows is prevented by a bracket 6 co-operating with a stop nut 7. The secondary windings 10, 11 of the transformer are connected to filter and phase shift circuits 20, 21 for removing harmonics and ensuring phase opposition of the output signals. The output of circuit 20 is connected to a phase sensitive rectifier 26 whose controlling phase is derived from a connection between circuits 20, 21. The output of rectifier 26 is compared in a comparator 28 with the voltage fed to the primary winding 9, the adjustment of a calibrated knob to produce a zero output being indicative of the ground water pressure. The circuits 20, 21 and a calibration adjustment 23 are mounted on a printed circuit board 12 connected to the surface via a cable 13 which also allows equilization of the pressure of the air in the probe with the ambient air-pressure.

Title: Preparation of a mixture of lactams and polyamides
Inventor: JOHNSON DAVID HAROLD
IPC: C07D201/08
Filed: 1964-03-04
Abstract: Mixtures of lactams with the corresponding polyamides are prepared by reacting a lactone of 4-8 carbon atoms with ammonia, present in at least 15 molecular proportions per mol of lactone, in the presence of hydrogen and a hydrogenation catalyst at elevated pressure and temperature.  Specified lactones are butyrolactone, valerolactone, caprolactone, methyl caprolactone, and dimethyl caprolactone.  The catalyst may be Raney nickel, nickel-on-kieselguhr, cobalt-on-kieselguhr, palladium-on carbon or platinum oxide.  The lactam and polyamide may be separated by fractional distillation. The polyamide may be hydrolysed, e.g. with aqueous mineral acid to give an amino acid which is recovered by absorption on an ion exchange resin, e.g. those of the basic type containing quaternary ammonium groups. The examples relate to the treatment of caprolactone and butyrolactone with ammonia in the presence of hydrogen and Raney nickel. By-products in the treatment of caprolactone are hexamethylene diamine and hexamethylene imine.  The polycaprolactam is hydrolysed to 6-aminocaproic acid, which may be then converted into its benzoyl derivative.  Reference has been directed by the Comptroller to Specification 1,052,681.

Title: Improvements in or relating to electron discharge devices employing magnetic focussing arrangements
IPC: H01J29/66
Filed: 1937-04-01
Abstract: 496,751. Cathode - ray tubes. MILLER, H. April 1, 1937, No. 9255. [Class 39 (i)] In electron-discharge devices employing magnetic focusing for television, electron microscopes or telescopes, light transformers &c., electron images of different magnification are produced on a fixed screen by a non-homogeneous axially symmetrical magnetic field for focusing the electrons emanating from a source at a fixed distance from the screen and varying the strength of the field so as to focus on the screen successive images of different magnification. As applied to a television transmission tube shown in Fig. 1, an optical image is thrown on the photo-electric cathode 5 and the composite stream of electrons is focused on the mosaic screen 8 by the magnetic field produced by a short coil 7 in series with a rheostat 15 by which the strength of the field is varied in such a way that electron images of different magnification are focused on the screen 8. The coil, which may be provided with a gapped iron sheath, may comprise 12000 turns and magnification ratios of 2 : 1 and 3 : 1 are produced with a current of 22 and 52 milliamperes respectively. Alternatively, a permanent magnet with means for adjusting the strength of the field may be used either separately or in association with an electromagnetic system. Fig. 2 shows another television transmitting apparatus in which the optical image is projected directly on the photoelectric mosaic screen 18 and is scanned by an electron beam produced by traversing a photoelectric screen 5 with a light beam 19. The variation in the strength of the field, causes the electron beam to scan varying areas of the mosaic and produce long shots or close-ups of the transmitted image as described in Specification 458,750. The application to a light transformer is also described.

Title: Fully electronic overload protection device with provision for limiting the make transient current
IPC: H02H1/04
Filed: 1966-03-04
Abstract: 1,110,094. Protective arrangements. INTERNATIONAL STANDARD ELECTRIC CORPORATION. 4 March, 1966 [10 March, 1965], No. 9543/66. Heading H2K. An overload protective arrangement for a load RL, e.g. electronic apparatus, includes a control transistor Q4 in series with the load, the transistor being effective to interrupt the load current in the event of overload and also to limit the " making " current. When overload occurs, the transistor Q4 ceases to be saturated and the potential across a potentiometer R4, R5, R9 becomes such that a diode D1 is caused to conduct, rendering a transistor Q2 conducting. This so reduces the base current of the transistor Q4 that the transistor is cut-off. When the supply voltage is initially applied to terminals 1, 2, the charging current through a capacitor C renders a transistor Q1 conducting which initially prevents the diode D1 and the transistor Q2 becoming conducting. At the same time the transistor Q connects the emitter of a transistor Q3 to terminal 2 so that the transistor Q3 is rendered conducting if the load current is sufficient to render the diode D2 conducting. The transistor Q3 now takes part of the base current of the transistor Q4 so that the load current through the transistor Q4 is limited. When the capacitor C has become charged, the transistor Q1 ceases to conduct so that the transistor Q3 ceases to conduct and the transistor Q2 is rendered effective to conduct in the event of overload.

Title: Improvements in inking and distributing roller arrangement
IPC: B41F31/15
Filed: 1922-04-04
Abstract: 201,600. Marks, E. C. R., (Miehle Printing Press & Manufacturing Co.). April 4, 1922. Inking-apparatus. - The inking-rollers and vibrating rollers of a printing-press are mounted in a common support in such a manner as to be movable out of engagement with respect to each other when the rollers as a whole are moved into inoperative position, and means are provided for firmly locking the inking and vibratory rollers in contact with one another when they are in operative position. The rollers and their common support are removable as a single unit from the machine, and slip means are associated with the driving-mechanism of the vibratory rollers to prevent excessive endwise movement which might result from operation of the press for a fraction of a cycle while the rollers are in inoperative position. The vibratory roller 15 is carried by brackets 20 rigidly secured to the shaft 17 by pins 21, and the inking-rollers 13, 14 are carried by brackets 16 loose to the shaft 17 but having widened slots 18 engaging feathers 19 thereon, so that when the rollers are swung into inoperative position, as shown by dotted lines in Fig. 3, the roller 15 is separated from the rollers 13, 14, the brackets 16 of the latter having stops 22 engaging a cross-bar 23. For firmly locking the rollers in contact with each other when they are in operative position, the brackets 20 of the vibratory roller 15 are provided with stop buttons 24 adapted to contact with stops 25 on the brackets 16 of the inking rollers, these stops being held in contact by locking-devices 26, Fig. 5, each operated by a handle 29 and having a semicircular flange 28 adapted to be turned behind a pin 27 on the brackets 20. The shaft 17 supporting the brackets and rollers is held in the impression cylinder frames 12 by means of projecting members 31 engaging slots 30 in the brackets 20, so that, by slipping the slots over the projections 31, the shaft 17 and its attached brackets and rollers may be detached from the machine as a single unit. Excessive endwise travel of the operating screw 37, Fig. 7, of the vibratory roller 15 is prevented by the following means. The screw 37 works in a nut 38 rotatable within a bearing 39, the friction between nut and bearing being sufficient to prevent rotation of the nut during normal running of the machine. Collars 40, 44 rigid with the screw carry projections 41, 45 adapted to co-operate with projections 42, 46 on the sleeve nut 38. If the press is moved whilst the rollers are in inoperative position, it may happen that on bringing the rollers again into operative position the time relationship of the vibrating roller to the other operative pressparts is disturbed, tending to displace the screw 37 beyond the limit of its endwise movement in one or other direction. In that event, one of the projections 41, 45 will engage one of the projections 42, 46 on the nut 38 and rotate it in its bearing 39, thereby preventing excessive endwise travel of the screw.
