Title: Improvements in infeed conveyor mechanism for feeding containers to an operating machine
IPC: B65B43/52
Filed: 1958-12-15
Abstract: 882,446. Endless conveyers for feeding containers. UNIVERSAL LABELLING MACHINES Ltd. Dec. 15, 1958 [Sept. 22, 1958], No. 40414/58. Class 78 (1). In apparatus for feeding containers 8 to an operating machine, e.g. a labelling machine, the containers are conveyed in closely abutting relation between a pair of laterally adjustable guides 29, 30 to a spacer wheel 21 by a slat conveyer 10 which is provided at intervals along its length in place of the normal slats, with plates 18 each carried by an arm 19 pivoted to one of the connecting pins of the conveyer chain, a cam track 22 engaging the under surface of these links 19 at a point immediately beyond the spacer wheel 21 to cause the plates 18 to rise into a position where they positively engage the containers 8. The containers 8 are then propelled by the plates 18 along a deflector 23 which transfers them, in timed relation, into spaces between adjacent V blocks 7 carried by a second slat conveyer 12 so as to lie between the laterally adjustable guide 26 and the deflector 23 which is also laterally adjustable. Subsequently, the containers contact a stationary peg 67 which causes them to topple over on top of the V blocks 7 so that they are fed in a horizontal position to the labelling machine. The spacer wheel 21 has teeth, each of which comprise a radial face 34 and a face 35 which extends at right angles to the radial face of the next tooth. The spacer wheel is carried on a vertical shaft mounted in a subframe which is adjustable to vary the lateral spacing between the teeth of the spacer wheel and the guide 29. The spacer wheel is driven from the drive to the conveyers 2 and 10 through an overload-release clutch comprising a driving member 41, Fig. 6, which is provided with radially extending grooves around its upper periphery and a driven spider 40 carried by a sleeve 38 on which the spacer wheel 21 is mounted, the spider 40 carrying rollers 39 which are urged into engagement with the grooves 42 by springs 65, 66. A toothed member 59 is secured to the spider 40, while a second toothed member 60 is mounted for vertical sliding on the sleeve 38 and is prevented from rotating by frictional engagement with a plate having rods 61, 62 engaging vertical slots 63 in a casing 64. When an overload occurs owing to jamming of a container 8 between a tooth of the wheel 21 and the guide 29, the rollers 39 ride upwardly out of the grooves 42, causing the lower toothed member 59 to move upwardly into engagement with the upper toothed member 60 to lock the spacer wheel 21 against rotation until the jam has been cleared. Specification 760,628 is referred to.

Title: Improvements in Oxidising Asphalt
Inventor: WAEGENAERE RENE
IPC: C10C3/04
Filed: 1967-09-05
Abstract: 1,179,578. Oxidizing asphalt. ESSO RESEARCH & ENG. CO. 16 Aug., 1968 [5 Sept., 1968], No. 40550/67. Heading C5E. In a process for oxidizing asphalt and bitumens by blowing or sucking air through the molten asphalt in a reactor at 400‹ to 600‹ F., in which FeCl 3  is used as a catalyst, an aqueous solution of FeCl 3  is introduced below the level of the molten asphalt through a nozzle located away from the walls of the reactor. The nozzle is preferably mounted near the asphalt inlet. Separate supply tanks for the solution and for water are provided, and in continuous operation the water may be mixed with the solution in a common conduit leading to the reactor to dilute the solution to prevent clogging of the nozzle. In batch operation, a concentrated solution may be used, the water being delivered periodically to the nozzle when the solution is cut off.

Title: Method of and Apparatus for Compensating for Timing Errors in a Monochrome Television Signal
IPC: H04N9/89
Filed: 1966-09-12
Abstract: 1,154,474. Automatic phase control systems. FERNSEH G.m.b.H. 12 Sept., 1966 [11 Sept., 1965], No. 40648/66. Headings H3A and H4R. Timing errors in a television signal, e.g. from a magnetic recorder, are compensated by adding a high frequency signal, locked in phase with the line synchronizing signal, to the signal during line blanking intervals and comparing the phase of this high frequency signal with that of a second high frequency signal which is locked in phase with line synchronizing pulses from a reference source. An error signal derived from the phase comparison controls a delay device through which the television signal is passed to compensate the timing errors. The system is preferably used after an initial stage of compensation for timing errors has reduced them to less than about 30nS. The high frequency signal to be added to the television signal during, e.g. the back porch interval may be derived from an oscillator switched on by the output of a monostable multivibrator which is triggered by the line synch. pulses of the signal, or it may be derived from a ringing resonant circuit which is excited by the differentiated leading or trailing edge of the line synch. pulse and whose damping is such that the oscillations decay substantially to zero in the period between synch. pulses. In a recording installation for colour television signals which may have a timing error compensator for limiting the phase deviations of the chrominance sub-carrier this same compensator may be utilized for timing error compensation, in which case a switch may be provided so that the compensator may be controlled by the chrominance sub-carrier during colour reproduction and by the high frequency signal phase comparator during monochrome reproduction. In such a case three comparatively simple compensators may be connected in series, Fig. 5 (not shown).

Abstract: 1511808 Electrolyte purity MITSUI MINING & SMELTING CO Ltd 25 June 1975 [1 Aug 1974] 40950/76 Divided out of 1508445 Heading G1B [Also in Division C7] The purity of an aqueous zinc sulphate electrolyte for use in the electrolytic production of zinc is determined by electrolyzing a sample of the electrolyte to produce a mixture of hydrogen and oxygen gases, igniting the mixture in a combustion chamber and measuring the pressure difference in the chamber before and after combustion, the pressure drop being an indication of the purity. Purified zinc sulphate solution is adjusted to the correct pH and electrolyzed in a cell 2 having a silver/lead anode 3 and an aluminium cathode 4. Combustion chamber 10 is filled with water to level L of an overflow 15 in tank 14 by opening supply solenoid valve 19, solenoid valve 20 and vent solenoid valve 23, drain solenoid valve 17 being closed. The hydrogen/oxygen gas mixture produced during electrolysis is collected by cover 9 and is used initially to purge pipe 9 and, if valve 11 is opened, it may also be used to purge the combustion chamber. Valves 19 and 23 are closed and valve 17 opened so that the water drains out of combustion chamber 10, valve 20 being closed when the water level falls to detector 21. The hydrogen/oxygen gas mixture is drawn into the combustion chamber and ignited by igniter 24, the mixture being stirred during combustion by magnetic stirrer 25, 26. A pressure detector 27 is used to measure the pressure drop caused by the combustion, and the hydrogen content of the gas mixture can be calculated. The purity of the zinc sulphate solution can be derived from the hydrogen content.

Title: Improvements in the manufacture of concrete conduit
Inventor: GAGNE ARCHIE R
IPC: B28B21/82
Filed: 1958-12-18
Abstract: 836,186. Moulding concrete conduits. GAGNE ENTERPRISES Inc. Dec. 18, 1958 No. 40969/58. Class 87(2). [Also in Group XXVIII] A machine for casting concrete conduits, comprising a vertical mould and cores and upper and lower pallets with openings in at least one pallet for the cores, has means, by which thrust is transmitted to the pallets and whereby the pallet with the core openings can pass into the mould among the cores without obstruction. A hollow rectangular vertical mould 22 is bolted to a deck 21 which also carries bearings 33 for rotatable cores 28. The cores are chain-driven and have intermeshing pinions ; e.g. 39, 41 which form one pair. A lower pallet 57 has openings corresponding to the cores, each opening 58, Fig. 4, having a tapered sleeve 55 to form a slight taper on the end of a duct 29 formed by the core. Similary, openings 67 in an upper pallet 66 are tapered : also the top of the mould is belled as at 64. The resulting conduit joint, Fig. 8, provides unobstructed passage from one duct to the next, The upper and lower pallets are movable from crossheads 69, 63 by hydraulic means. The upper pallet is suspended from the crosshead and a spring 68 is interposed. The crosshead has a guide 72 which slides on a rod 71. The thrust from the lower crosshead is transmitted through rods 62 which fit in sockets in a spider 59, Fig. 5, bearing against the bottom of the lower pallet 57. The disposition of the thrust rods and of the arms 61 of the spider, is such that they are able to move among the cores and drive the lower pallet up the mould without obstruction by the cores and without the thrust being off-centre. In operation, the upper pallet 66 is removed and concrete is poured into the mould from a hopper 77. With the upper pallet replaced, pressure is applied to both upper and lower pallets while the cores are rotated, and the mould is vibrated by a vibrator 78. After compaction both crossheads 63, 69 are raised, the pallet 57 and the spider 59 passing up through the mould and ejecting the casting, Fig. 4, which is removed in the fork arms of a transporter. The planes of the upper and lower pallets may be inclined, e.g, at 15 degrees, Fig. 11, to give a mitre on the ends of the conduits, so that they can be laid in a curve. By initially raising the lower pallet shorter conduits can be cast. The cores may be oscillated instead of rotated. There may be different numbers of thrust rods with appropriately shaped spiders.

Title: Prevention of double processing in object identification sytems
IPC: G07B15/06
Filed: 1973-09-04
Abstract: 1462055 Vehicle identification systems NATIONAL RESEARCH DEVELOPMENT CORP 27 Aug 1974 [4 Sept 1973] 41446/73 Heading H4L An object identification system is of the kind wherein a transmitter on the object transmits signals representing identifying codes to receivers located on a route taken by the object and wherein storage arrangements are coupled to store the codes received by each receiver, the stores being interrogated by a scanning arrangement which passes the codes to a processor which provides identifying information. In such systems it is possible for the identification codes from a particular object to be recorded twice, e.g. because the code is picked up simultaneously by two or more receivers or because during the repeated transmission of the same code by the same receiver, an error occurs such that a following code appears as a new record. To prevent this possibility, code signals from different receivers are compared, or at least three closely successive codes from the same receivers are compared, or both these comparisons are performed, and logic arrangements are coupled to the comparator to prevent the same code being passed more than once to the processor, when the same code is received concurrently from more than one receiver or when after a change in code occurs a reversion to a previous code takes place. In the described embodiments, the invention is applied to a road vehicle detection system. In one arrangement (Fig. 1) a vehicle may cross two receiver loops 14, 12 and be detected by both. The detected code is stored in both of registers 17, 18. The corresponding storage positions of these are coupled to exclusive OR gates 19-22. If all of these gates give zero output showing complete equivalence of store contents, AND gate 23 is operated, the inverter 24 gives a null output and thus AND gate 25 is turned off to prevent the signal from receiver 26 being passed to the scanning arrangement in the processor. In a second embodiment, for dealing with successive code signals (Fig. 2) the signals pass to a series of registers 30, 31, 32 and the code stored in the final register is compared with that in the preceding registers and in the register before that by respective comparators 33, 36. A scanner control prevents a record being made of any code until it changes. This control is not operated until enabled by AND gate 35 and this requires both comparators 33, 36 to show a difference in the codes compared.

Welding electrodes are tested to determine the maximum arc lengths due to the flux coating and core respectively under welding conditions by arcing an electrode to a steel plate and measuring the length A1 at which the arc extinguishes, arcing the electrode to a like electrode to obtain similarly a maximum length A2, arcing the electrode to a like electrode having its coating removed to obtain a maximum arc length A3, and repeating the tests with electrodes of another type to obtain values B1, B2 and B3. This data is then used to calculate the required lengths. Thus, e.g. supposing the two electrodes have like cores, the arc length due to the flux coatings of the electrodes are stated to be K(A2 - A3) and K(B2 - B3), where The sum of the arc lengths due to the coating and the core is stated to be equal to A1 or B1 respectively.

Title: Improvements in or relating to automatic register control,for example for multi-colour rotary printing machines
IPC: B65H23/188
Filed: 1963-10-25
Abstract: 1,68,297. Automatic registration control. SIEMENS - SCHUCKERTWERKE A. G. Oct. 25, 1963 (Oct.26, 1962], No.42291/63. Heading G3R. In a system for automatically registering two elements driven by a machine, signals produced by timing marks associated with the two elements and a signal dependent on the speed of one of them are combined to produce pulse trains, variations in the number of pulses in which are utilized to correct the registration. In an automatic registration control system for a multi-colour printing machine, marks on two moving elements to be synchronized or corresponding marks printed on the web produce two trains of electric synchronizing pulses. By means of a system of logic circuits and flip-flops the order of occurrence of corresponding pulses in the two trains and the interval between them, representing the sense and magnitude of register deviation, is periodically detected. If the deviation exceeds a predetermined value, separate pulses having a repetition frequency proportional to the speed of the printing machine are applied to increase or decrease, according to the sense of deviation, the datum count of a counter. If the increase or decrease in count exceeds a predetermined value an appropriate motor is started, to correct the deviation, at the end of the measured interval between the synchronizing pulses. During operation of the correcting motor, further pulses from a reference source are applied to restore the counter to its datum count, whereupon the motor is stopped and has operated for a period corresponding to the deviation. In order to alter the position of registration, the count of the main counter may be modified to a predetermined extent at the end of the measured interval, or the synchronizing pulses may be arranged to trigger trains of references pulses one set of which is delayed to a predetermined extent by interposing an auxiliary counter which does not produce an output until a predetermined count is exceeded.
