Title: Packaging machine
IPC: B65B13/18
Filed: 1961-11-15
Abstract: 961,688. Bundling machines. METAVERPA. N. V. Nov. 15, 1961 [Nov. 15, 1960], No. 40827/61. Heading B8C. A package binding machine of the kind comprising a table for supporting the package within a guide truck round which binding material is fed and then tensioned and secured about the package comprises means whereby the package is displaced clear of a stop which it contacts initially to trigger off a working cycle of the machine. The machine shown has a roller conveyer table leading through the guide track 4, the rollers 5 being retractable during binding. Two stops 8, 9 are provided and behind each extends a member 22 (shown in plan, Figs. 2, 3), capable of movement at right-angles to its length by pneumatic cylinders 16, 17. Elements 23-31 ensure parallel movement throughout. The package first strikes the stop 8 and binding occurs, followed by forward movement of the member 22 to the position of Fig. 3. The package is thus cleared from the stop and when the member 22 retracts, may advance and contact the second stop 9 to initiate a further binding operation; 22 then again advances to push the package clear of the stop 9. Operation of the member 22 may be controlled by pressure changes in the pneumatic binding material tightening system in a machine, the member operating before completion of the tightening to force the package in the direction of the tightening movement. Means may be provided to prevent operation of the member until twisting and cutting of the binding material is complete.

Abstract: 1,046,762. Route setting systems. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Nov. 13, 1962 [Nov. 15, 1961], No. 40861/61. Heading B7N. In a route-setting system in which a route is selected on a track diagram by means of push-buttons defining its ends and wherein each points of a route is controlled by a pair of double-latched route command relays, one of which is switched to its reverse position for controlling the points to one of its two positions, means are provided, on selecting a route, for making operation of the first route command relay in the route conditional on operation of the route selection switches and the operation of each subsequent route command relay conditional on the operation of the preceding route command relay in the route. The track layout shown in Fig. 1 comprising track sections 10T-14T includes points 11 and 12 which require setting to normal to provide a route between sections 10T and 14T, i.e. the double latched route command relays 11NUR and 12NUR associated with the normal position of the points must be released from their normal latched position and switched to reverse. On operating push-buttons 1 and 3 start relay 1SR (not shown) and destination relay 3DR (not shown) pick-up and complete a circuit between terminals 1B50 and 1N50, and a repeat relay 1UER (not shown) of the start relay picks up and opens the energizing circuit of relay 11NUZR. Release of 11NUZR opens the short-circuit across the normal release and reverse energizing coils of relay 11NUR and the release winding of the relay is energized which opens a short circuit across the reverse energizing coil or front contact 11NUR(N) and shorts out the release winding at back contact 11NUR(N). The reverse coil is now energized and the relay latches in its reverse position. This energizes a relay 11NURPR which on pick-up shorts out the reverse winding of relay 11NUR and releases relay 12NUZR. The energizing voltage is now applied to the normal release winding of relay 12NUR which is subsequently switched to its reverse position in a similar manner, followed by the reverse switching of route finish relay 13TUR.

Title: Process for removing catalyst material from polymeric material
IPC: C08F6/02
Filed: 1962-10-29
Abstract: In a process for removing catalyst material from polymeric material prepared with the aid of an organo-metallic catalyst or catalyst component, methanol is added to liquid which contains said polymeric material in suspension and in which such methanol dissolves at the obtaining temperature.  Then two liquid phases are formed, one of which contains all or most of the polymeric material and which contains at least 5% by volume of dissolved methanol. The two phases are kept in contact for at least three minutes and then separated. The addition of methanol is generally carried out in the absence of oxygen and at a temperature between 45 DEG  and 95 DEG  C. for at least 15 minutes.  The two liquid phases can be formed by cooling e.g. to 20 DEG  C. or 3 DEG  C., or by adding a polar liquid e.g. ethylene glycol or sulphuric acid or on a large scale by adding water or a water/methanol mixture.  The phase separation results in a lighter liquid phase containing at least 5, and preferably 8 to 20% by volume of methanol, and in which the polymer particles are suspended, and a heavier liquid phase, and the contact time is preferably at least 15 minutes. When water is added to form the two phases it is preferably added gradually. After the contact period more water may be added before the phases are separated.  The process may be carried out continuously.  In the examples polyethylene prepared by using diethylaluminium chloride and titanium tetrachloride as catalysts, is purified.

Title: Bobbin-changing device with automatic means for severing the thread or strip
IPC: B65H67/04
Filed: 1976-10-01
Abstract: 1509666 Doffing and severing the yarn leading to the doffed package SANT' ANDREA NOVARA OFFICINE MECCANICHE E FONDERIE SpA 1 Oct 1976 [3 Oct 1975] 40978/76 Heading D1J The invention is concerned with means for breaking a yarn leading to a fully wound package close to the periphery of the package. In Fig. 1 when the fully wound package, shown in an unbroken line is doffed, it is allowed to fall downwards. During this fall a frictional member 13 in engaged by the periphery of the package at a position on the opposite side of the axis of the bobbin to the position at which the material being wound reaches the periphery of the package. This causes the point at which the yarn reaches the periphery of the package to be accelerated in the wind - up direction and so cause the yarn to break at this point. The frictional member 13 is spring biassed to the broken line setting. The package is carried by a pair of arms 6 pivoted at 7 so as to press the package against a drive roller 4. The yarn is traversed onto the package by traverse means 5. When the package is fully wound the arms 6 rock anti - clockwise to allow the fully wound package to fall past the frictional member 13. When a package has been fully doffed the arms 6 can pick - up an empty bobbin 8 and a pinion 11 meshing with a toothed sector 9 is then used to swing the empty bobbin up into the winding position.

Abstract: 980,513. Semi-conductor devices. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Nov. 17, 1961, No. 41266/61. Heading H1K. A silicon body to which material is subsequently alloyed to form a PN junction is prepared by etching in a solution containing nitric and hydrofluoric acids, to which before or during etching, alkali or alkaline earth metal ions are added. In a typical process silicon discs are etched to within 40Á of the required thickness in a solution of 2-4 volumes nitric, 4-2 volumes hydrofluoric and 6 volumes acetic acid of specified concentration and rinsed in deionized water. After etching to the desired thickness in a fresh solution of the acids a 10% by weight solution of an alkali or alkaline earth salt is added to form between 2 and 10% of the solution and etching continued for two minutes while the solution is agitated. The discs are then rinsed in deionized water and stored in alcohol until the alloying process. Suitable salt solutions are the chlorides, nitrates or carbonates of magnesium, calcium, barium and strontium. The method is said to be particularly suited to the production of rectifiers, transistors and photo-cells.

In an arrangement for generating the carriers for a multi-channel high-frequency transmission system a travelling-wave tube 4 is fed on its high frequency input with a signal whose frequency is equal to the mean carrier frequency of the transmission band, and derived from a crystal stabilized source, 1, via a multiplier, divider, or amplifier, 2, while between the cathode, and the acceleration and/or delay line electrode of the tube is fed a signal of frequency equal to the carrier spacing, derived by multiplication or division of the output of the same crystal oscillator via multiplier or divider 3, or derived from a second crystal oscillator (12, Fig. 3, not shown). The various carriers are then derived from the travelling wave tube output using a notch filter 5. An arrangement for providing the carriers for a two-way system utilizing a halfband for each direction of transmission is shown in Fig. 2. The carriers for one half-band are derived in an identical manner to that shown in Fig. 1 with a frequency selective splitter 6 feeding a selected frequency from that band to a mixer 7 where it is shifted by a frequency, derived via multiplier or divider 8 from the oscillator 1, equal to the centre spacing of the two half-bands. The resulting frequency is applied to the high frequency input of a travelling-wave tube 9, fed between its cathode and delay electrodes with a frequency, derived from the oscillator 1 via multiplier 10, equal to the carrier spacing in the second half-band. In alternative arrangements one or more of the multiplier/dividers 2, 3, 8 and 10, may be supplied from independent oscillators in order to simplify the choice of frequency and multiplication or division ratio, Figs. 4 and 5 (not shown). In an arrangement providing reserve capacity in the event of failure of the equipment, Fig. 6 (not shown), the oscillator, multiplier/dividers, and travelling-wave tube may be duplicated and fed to the notch filter (5) via a high-frequency switching device (15) switching from the normal equipment to the standby equipment in the event of failure of the normal equipment.

Title: Improvements relating to weighing apparatus
Inventor: WOLVERSON OLIVER ARTHUR GERALD
IPC: G01G1/00
Filed: 1961-11-23
Abstract: 1,001,257. Weighing apparatus. W. T. AVERY Ltd. Nov. 9, 1962 [Nov. 23, 1961], No. 41910/61. Heading G1W. Relates to a weighing apparatus in which weights are selectively deposited or removed on or from a lever system in order to change the measuring capacity range. As shown a load counterbalancing lever system comprises a lever 1 fulcrumed at 2 and supporting a load from bearing 3 and connected to a lever 7 fulcrumed at 8 on a shackle 9 suspended from a weighing lever 10. The lever 7 is linked to an indicator lever 14 fulcrumed at 15 and connected at bearing 16 to an indicator mechanism of known type having a pointer 18 a chart (not shown). Range selection. The lever 10 is responsive to any load within the total capacity of the apparatus and is connected to a spring resistant 25 and carries a rack 26 which engages a pinion driving a disc 27. The disc 27 bears a series of numerals e.g. 1 to 10 which correspond to the number of weighing ranges and in operation the capacity range in which the load is to be counterbalanced is indicated, in a window 28. Change weight mechanism. A counterweight carrier 29 is hung from a bearing 30 on the indicator lever 14. The capacity change weights 32 have eyes 34 for engagement by solenoid 35 operated bolts 36. The solenoids 35 are mounted on a carriage 37 which is raised up and down by a motor 40 through a scissor type linkage 38. In operation, according to the range indicated by the lever assembly 10, a push button switch is manually operated which causes solenoids 35 to be energized appropriate to the required combination of capacities change weights 35, and also energizes motor 40. The motor drives and lowers the carriage 37 to align the solenoid bolts with the eyes 34. When the carriage is in its lowest position a cam (not shown) on the motor shaft operates a switch to de-energize solenoids 35 appropriate to the unwanted weights 32, whereupon these solenoids project their bolts through the eyes of all unwanted weights which are thereby lifted off the carrier 29 as the carriage 37 is raised while the required weight combination remains. The motor also moves a linkage 42 to rotate a chart backplate 21 so that the appropriate major weight indicia 19, 20 appear through the windows 22, 23. The system may be fully automatic wherein the weighing lever 10 serves to automatically actuate a rotary selector switch adapted to initiate the operations instead of the manual push button switches.
