Title: A method and apparatus for synchronizing the movements of a plurality of individually driven power devices
IPC: H02P5/46
Filed: 1966-09-14
Abstract: 1,146,279. Automatic position control. T.N. LJUNG. Sept. 14, 1966, No.40996/66. Heading G3R. [Also in Divisions H1 and H2] The step-wise movements of a number of jacks are synchronized by periodically stopping movement of each jack which is in advance of the slowestmoving jack until co-ordination is restored by continued movement of the latter. When brushes 29, 35, engage drum 25 which is driven by pilot motor 23, an electric motor 7 is energized so that a pump unit operates to raise its suspension rods 10. As soon as the rod has advanced one step, switch 21 is closed for a short period to energize coil 37 whereby brush 35 is disengaged from the drum 25 and brush 34 is brought into contact with it. If the brush 34 then engages insulating strip 27, the circuit of the motor 7 is broken and the pumping unit stops. If, however, brush 34 engages conductive strip 28, coil 36 is energized to return the brushes to their original positions so that operation of the motor 7 is not interrupted. A pumping unit which has stopped is restarted when the brush 34, after first engaging the insulating strip 27, on further rotation of the drum contacts the portion 28. A drum 25 is associated with each of the motors 7, the speed of the motor 23 being chosen so that the progress of the slowest jack is uninterrupted. By adjustment of the respective metering valves of the pumping units the speed of the motor 23, and the angular positions of the rear edges 27' of the strips 27 with regard to the shaft 24, the jacks may be made to operate continuously over a number of successive steps before their time lead over the slowest jack is such that they are halted. In another arrangement, the drums 25 are replaced by discs each having a permanent magnetic part in the form of a sector for operating an adjacent switch which is in series with the switch 21 and the coil of a relay having contacts in circuit with the motor 7. If one of the jacks has obtained such a lead over the slowest jack that, at the moment of actuation of switch 21, the permanent magnet has not yet reached the adjacent switch and the latter is closed, the pump motor circuit is interrupted and the switch 21 is shunted by holding contacts. Operation of the pumping unit is restarted when further rotation of the disc causes the adjacent switch to open.

Title: Method of making paper and non-woven materials
IPC: D04H1/00
Filed: 1962-11-01
Abstract: Paper is formed from synthetic fibres, glass fibres and mixtures of these fibres with natural fibres by processing the fibres into a bath on a paper-making machine in association with a lubricant in the form of a natural or synthetic resin-like or wax-like material and with an adhesive in the form of a condensable and/or polymerizable or esterifiable material having a higher melting point than the lubricant, the lubricant and adhesive being immiscible in the fluid state when heat is applied, exposing the fibres to a temperature of 50-120 DEG C. so that a coating of liquefied lubricant is formed on the fibres along which the melted adhesive moves to the points where the fibres intersect, hardening the adhesive, and if necessary washing out the lubricant.  Initially some or all of the fibres may be beaten in the lubricant and then centrifuged to remove the surplus lubricant.  The fibres may then be steeped in the adhesive to provide a second coating, or the adhesive may be added in fibre or granular form.  Alternatively the adhesive may be in fibre form coated with the lubricant or a homogeneous mixture of the two additives may be formed into threads or powder.  The bath may be heated by being passed through heated rollers.  The fibres may be made of regenerated cellulose, a polyamide, a polyester, a polyvinyl, an acrylic polymer, a polyolefin or a mixed polymer. Lubricants mentioned are paraffin wax, silicone emulsions, ammonia, or other alkali resin soaps, and an alkyl glycol phthalate, adipate or sebarate.  Suitable adhesives are isocyanates mixed with polyesters, or an epoxy resin and a polyester.

Abstract: 1,203,262. Shutters. EASTMAN KODAK CO. Sept.20, 1967 [Sept.21, 1966], No.42747/67. Heading G2A. A camera shutter comprises a blade 1 which normally covers the aperture 10, and another blade 2 which is held in the position shown by a latch 3. The latch is held against the action of a spring 11 by an electromagnet 4 energized from a battery 12. Across the battery is a resistor 14 and photo-cell 7. The battery also biases the base of a transistor 8, through which current passes to the electromagnet. Thus this current is inversely proportional to the amount of light falling on cell 7. When exposure is initiated, a member 5 swings round, breaking a switch contact 6, and so shutting off transistor 8, and hence the current to electromagnet 4. At the same time, member 5 strikes a lug on blade 1, causing it to swing aside and uncover aperture 10. The current energizing the magnet decays through a resistor 9 connected across its leads, and when this drops sufficiently, latch 3 is pulled away by spring 11. Blade 2 is thus released to swing, either under gravity or a spring, to close aperture 10 again.

Abstract: 435,408. Starting and stopping mechanisms. BRITISH UNITED SHOE MACHINERY CO., Ltd., KEALL, F. B., and MAWBEY, L., Belgrave Road, Leicester. March 20, 1934, No. 8664. [Class 103 (i)] Starting and stopping mechanism, more particularly for shoe machinery, comprises a rotary member 1 adapted to be braked by a brake 7, the brake mechanism comprising an inertia device which on the mechanism being operated for stopping, causes a substantial braking effort to be applied to the member 1 and thereafter relieving by its movement the braking pressure set up in the mechanism. Driven member 1 is moved into engagement with the driving pulley 5 by springs 8 and with braking disc 7 by lever 21 pivoted at 23, link 19, lever 11 pivoted at 13 and cam 9 on the main shaft of the machine. A weighted lever 31 is fixed to a spindle 29 journalled in the bottom of the lever 21 and has a lug 33 adapted to engage lugs 35, 37 on the lever 21. The link 19 is freely pivoted on an eccentric part 27 of the spindle 29 and has a block 17 engaging a block 15 on the lever 11. When the link 19 is depressed by a treadle-operated catch 49 to disengage blocks 15, 17 and allow the springs 8 to engage the member 1 with the driving pulley in order to drive the machine, the weighted arm 31 falls and engages the lug 33 with the lug 35 and the link 19 moves slightly to the left relatively to the lever 21 owing to the eccentric spindle 29. When the treadle is released, blocks 15, 17 re-engage and member 1 is moved against the disc 7 and the inertia of the arm 31 at first prevents turning movement of the eccentric spindle 29. Subsequently, the pressure on the disc 7, the clutch springs and the operating connections react and the weighted arm 31 springs up, rotating the eccentric and shortening the effective length of the arm 19, thus relieving to a certain extent the pressure of the member 1 on the brake disc and the pressure in the mechanism, allowing easy disengagement of the blocks 15, 17. To allow the machine to perform one revolution only, the catch 49 may be only partially depressed when releasing blocks 15, 17, whereupon a block 57 prevents catch 49 moving with link 19 which is released from the catch and moved by the spring 20 against the underside of the block 15 and when the block again moves to the left, blocks 15, 17 re-engage to release the member 1 from the driving pulley and engage it with the brake disc 7. When the catch 49 is wholly depressed, cut-away parts 61, 63 on the block 57 and the catch 49 respectively allow the catch 49 to move to the left with the link 19 and these parts to remain in engagement. Specifications 15555 /08, [Class 17], 429,746 and 430,984, [both in Group VII], are referred to.
