Abstract: 388,038. Cartons. ALEXANDER, A. T., 21, Hilton Mansions, West Street, Durban, South Africa. Aug. 11, 1931, No. 22731. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 13, 1932.] [Classes 18, 66, 94 (i), and 94 (ii).] In a carton for liquids, semi-liquids, powders, &c. made from a blank of pliable material, e.g. cardboard, paper, with the upper ends of the sides connected together and inwardly folded to close the top, the bottom is formed by five overlapping, quadrilateral, projecting flaps 2, 3, Fig. 4, each of which is of greater length than half the width of the bottom, and one, 3, is of approximately the full area of the bottom, so that the bottom is reinforced at its centre part. The top closure is formed by folding down the upper ends of the sides, as shown in Fig. 1, and folding the strip 7 over the upstanding strip 5 on the opposite side. To seal the top closure, the wax with which the carton is coated is melted, and metal fasteners are passed through the upstanding folds, or an-shaped metal strip is placed over them and secured by indenting. The ends of a wire handle can be slipped through the #-shaped clip. The carton may be of square, rectangular, &c. form with tapered or straight sides. The contents are poured out through an aperture made by turning back the flap produced by one of the piercing tools shown in Fig. 3. The Specification as open to inspection under Sect. 91 comprises also that, to seal the top closure, heat is applied by serrated tongs which indent or corrugate the material at the sealing folds. This subject-matter does not appear in the Specification as accepted.

Abstract: 974,257. Pulp supply in paper-making machines. DOMINION ENGINEERING WORKS Ltd. June 14, 1962 [June 15, 1961], No. 22977/62. Heading D2A. Pulp supply apparatus for a paper-making machine includes a passage connecting a supply duct with a discharge orifice, the passage including a 180 degrees bend and being reduced in cross-section at the bend to cause acceleration of the fluid stock. Although a single passage may be employed it is preferred that fluid from external supply ducts should enter by a pair of opposed upper and lower conical inlets 13,14 dimensioned to maintain constant pressure over their lengths. From the conical inlets the fluid is then directed through orifices 28, 29 so arranged relative to the slice lips 25 as to discharge the fluid from the orifices parallel to the direction of flow from the slice. Fluid from inlets 13,14 combines and mixes at 32, is accelerated through orifice 33 into deceleration chamber 34, followed by acceleration through slice lips 25. A rectifier roll may be mounted in the deceleration chamber. Air trapped in inlets 13, 14 escapes through holes 35, 36 into ducts 37, 38 vented to atmosphere. The slice lips 25 form a part of a flexible member 23 that may be adjusted for height, graduated scales and indicators being provided.

Title: An improved method of and means for synchronizing rotating bodies
IPC: H02P5/50
Filed: 1925-09-15
Abstract: 240,442. Lorenz Akt.-Ges., C. Sept. 25, 1924, [Convention date]. Synchronous movements.-Two rotating members, e.g. in a telegraphy or television system, are synchronized by transmitting an alternating current having a frequency corresponding to the speed of the member at the transmitting station, and having a definite phase relation thereto, to a cummutator driven by the member at the receiving station, applying the output current from the commutator to the grid-filament circuit of a thermionic valve, and using the plate current to apply speed corrections to the member at the receiving station. Fig. 1 shows a commutator C driven by a motor R which is to be synchronized with a generator S at the other station by transmitting from the generator to the commutator over the line L a current having a definite frequency and phase in relation to the speed and phase of the generator. The commutation is arranged to be effected at the maximum values of the current when the speed and phase of the motor R corresponds with those of the generator S. Under these conditions the output current from the commutator remains zero until a loss of synchronism occurs. This output current is applied through a transformer Tr to the gridfilament circuit of a thermionic valve T, and the resulting current from terminals e, f in the plate circuit is utilized to correct the speed of the motor, e.g. by applying it to a field coil of the motor or to the coil of an eddy-current brake. Fig. 4 shows, an arrangement in which a more accurate synchronism is obtained by the use of a second valve to eliminate hunting. The motor R drives the commutator C and a member V adapted to be braked by eddy-current action upon energizing coils c1 or c2. The commutated received current is applied to the grid-filament circuit of a valve V, of which the plate circuit includes the braking, coil c, as in the arrangement of Fig. 1. This plate circuit includes also the primary of a transformer Tr, the secondary being connected as shown to the grid-filament circuit of a second valve T2 of which the plate circuit includes the braking coil c2. The subjectmatter claimed in Specification 234,529 is disclaimed. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the invention to the electric control of clocks. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to Wired Broadcasting Systems

IPC: H04N11/16
Filed: 1966-05-27
Abstract: 1,160,862. Colour television; wired broadcasting. COMMUNICATIONS PATENTS Ltd. 19 May, 1967 [27 May, 1966], No. 23879/66. Headings H4F and H4R. A wired broadcasting system comprises a transmitting apparatus 1 which receives PAL type colour television signals radiated from a broadcasting transmitter and modifies them for transmission on conductive network 2, 3 to receivers 6 and 7. In the transmitter 1 the received signals are fed to device 16 which provides on line 17 brightness information and suppressed carrier wave colour carrier information in respect of first and second colour carrier information signals, the phase of the second colour carrier information signal being periodically reversed, on line 18 line scanning pulses, and on line 19 colour bursts. The bursts are fed to a comparator 20 and frequency control arrangement 24 to synchronize an oscillator 21 which generates a pilot carrier wave at the burst frequency. The frequency of the pilot carrier wave is doubled, 26, and phase inverted, 30, every line and the resulting oscillations are modulated, 32, by the brightness and colour carrier information on line 17. After passing through a vestigial sideband filter 34<SP>1</SP> and being added, 25, to the pilot carrier wave, the signal transmitted over conductors 2, 3 comprises a brightness information carrier component having a carrier wave 8, a suppressed carrier wave colour sub-carrier information component in respect of the first and second colour carrier information signals, having a suppressed sub-carrier wave 10, and a pilot carrier wave 12, the phase of the brightness and first colour information components being reversed at line frequency. The frequencies of the pilot carrier wave 12, the carrier wave 8 and the suppressed sub-carrier wave 10 are related in the ratio 1:2:3. In the receiver 6 the signals from conductors 2, 3 are fed to a bandpass filter 37 which selects the brightness and colour information components. These signals are amplified, 38, and demodulated by an envlope detector 39 to produce on line 40 a brightness information signal of video frequency. The suppressed carrier wave colour sub-carrier information signals are derived from the output of detector 39 by means of a band pass filter 41 and two synchronous detectors 42 and 43. The second colour information signal is obtained from detector 42 by means of a re-insertion carrier wave of constant phase derived from the pilot carrier wave by means of a narrow band pass filter 44 and amplifier 45. The first colour information signal is obtained from detector 43 by means of a reinsertion carrier wave the phase of which is reversed at line frequency derived from a balanced mixer 48 fed with the amplified pilot carrier wave and the brightness carrier wave, the phase of which is reversed at line frequency. The brightness carrier wave is derived from the output of amplifier 38 through a narrow band pass filter 49.
