Patent JP-S60143987-A (JP)
Title: Paper-feeding mechanism for printer
Inventor: IKEDA HIROSHI
IPC: B41J13/02
Filed: 1984-01-05
Abstract: PURPOSE:To enable a paper to be securely fed without exerting immoderate forces on the paper and facilitate fitting the paper, by a construction wherein a switching lever is provided so that the pressure with which a pressure roll is pressed against a paper-feeding roll can be changed, and the pressure roll can also be separated from the paper-feeding roll. CONSTITUTION:A click spring 6 is engaged to a groove 46 of the switching lever 4, and the first and second leaf spring pressing parts 41, 42 of the lever 4 are out of contact with a leaf spring 3. In this condition, therefore, the pressure roll 2 presses the paper against the paper-feeding roll 1 with the elastic force of the spring 3 itself, namely, a low pressure, so that the paper pushed out from a pin tractor or the like can be suitably fed in an auxiliary manner, and the paper can be fed without exerting immoderate forces thereon. When feeding the paper by only the roll 1, a switching lever shaft 5 is rotated counterclockwise to engage a groove 47 of the lever 4 to the spring 6. By this, the pressure roll 2 presses the paper against the roll 1 with a high pressure, so that the paper can be securely fed.

Abstract: 1302511 Extruding rubber compositions UNIROYAL Inc 2 Jan 1970 [10 Jan 1969] 161/70 Heading B5A [Also in Division B1] A uniform volumetric discharge rate of natural or synthetic rubber material is obtained from an extrusion screw, by relieving an excess volumetric rate capacity of heat plasticized material from a region intermediate screw regions respectively of higher and lower volumetric rate capacity, by returning the excess material to the beginning of the higher capacity region through a passage separate therefrom. An extruder screw of lower capacity may be fed with the heat plasticized material from a separate screw feed extruder of higher capacity which may act to blend different materials, supplied thereto, e.g. by a force ram feed, and may be provided with water or steam temperature control means, the excess capacity being relieved from a conduit connecting the extruders through an orifice, which is replaceably located or is of the variable iris type, and conveyed by feedback means, e.g. an extrusion screw, to the supply of new material upstream of the inlet of the higher capacity extruder, with each extrusion screw having a separate variable speed drive. The excess capacity may be 10% in excess of the discharge rate, but may be as great as two or three times, e.g. for blending purposes. In the preferred embodiment, the excess capacity is relieved from a single extrusion screw 12 at a barrel orifice 27 and returned, by a separately driven screw 36, at a barrel orifice 17 to sections D, A of the screw 12, which is supplied with unplasticized material from a hopper 15. In section A, the extruder barrel 10 is provided with six start grooves 21, of gradually increasing depth towards, and slightly into, a region E 1  of a section E in which the orifice 27 is located, where the grooves 21 abruptly decrease to zero depth, the screw grooves 20 decreasing in depth over the same extent to zero at 23 in region E, where plasticized material is then transferred by the barrel grooves 21 into three start grooves 25 of the screw 12, which rapidly increase to maximum depth at the end of region E, where they merge into a single start screw groove 26. In further progress along section B, the plasticized material is further transferred between the screw grooves 26 and helical grooves 41, 42 provided in the barrel 10. The developed groove configurations of the screw 12 and barrel 10 are depicted in Figs. 3 and 4 (not shown).

Abstract: 674,632. Annealing. BIRLEC, Ltd., and SCHULTE, F. W. K. April 5, 1950 [Jan. 5, 1949], No. 245/49. Class 72 [Also in Group XII] In a method of heat-treating metal goods, the work pieces are passed continuously through a treatment chamber supplied with a circulating gas heated to a temperature in excess of that to which the work pieces are to be heated, at such a speed that they do not even locally overheat despite the relatively high temperature of the circulating gas. As shown, applied to the annealing of aluminium sheet or discs, the articles are conveyed by an endless belt 10 through a shallow treating chamber. A fan 8 draws air from one end 6 of the chamber and discharges it, through a heater 7, into the other end, the temperature of the air being controlled by a thermocouple 17, and the speed of the air by a thermocouple 18 at the fan inlet. The air may be supplied to the chamber at 700- 800‹C. and removed from the chamber at 100-300‹C. below the entry temperature, the speed of the conveyer being such that the work pieces are discharged at 450‹C. The time of treatment may be 1-3 minutes per millimetre thickness of metal. The work pieces may be removed in the direction of flow of the air or in the opposite direction.

Solid supply to liquid; removing sludge from generators.-The walls 15, 17 of the annular gasholder 16 are immersed in separate annular water chambers 13, 19, the inner chamber 13 enclosing the gas-generating chamber 9 and the carbidefeeding-mechanism. In the form shown, the wall 11 of the gas-generating chamber 9 forms the inner wall of the water chamber 13. The chamber 9 is closed at the top and provided with a conical base 10 cut into narrow radial flaps, which are bent outwards, so that the gas escapes in very small bubbles through the lime water in the vessel 23. Similar flaps 12 are formed in the wall 11. The carbide vessel 1 is provided with a valve 3 and a feeding-device 4 having upper and lower openings 5, 6 controlled by a vertically-operating two-seated valve 7. This is controlled by a rod 30 connected by a lever 33 to a rod 34 passing through the water inlet 27, 28 and provided at the top end with a button 35. Normally, this is held down by an arm 36 on the gas-holder having a hinged handle 39 with prongs 40, which engage a fixed arm 38 when the handle is in the position shown in Fig. 1. In order to start the generation of gas, the handle 39 is turned down, as shown in Fig. 5, and turned about the pivot 37, releasing the rod 34. This is lifted by hand and then lowered again and locked by the arm 36. This allows a supply of carbide to pass the valve 7. and the subsequent control of the valve is effected by the movements of the gas-holder. The water vessel 23 has a steeply inclined bottom 24 and a sludge outlet 25.

Abstract: 1460012 Automatic control of fuel supply in IC engines CAV Ltd 18 Dec 1973 [6 Jan 1973]  889/73 Heading G3N A control system for the fuel supply to an engine includes an electrical filter whereby small perturbations of a demand signal are ignored. The control system is similar to the one shown in Specification 1416861 and includes a pump output transducer 25, an engine speed transducer 15 and a demand transducer 33 all connected to the inverting terminal of amplifier 17. The demand transducer comprises a variable coupling transformer having a primary winding 34 connected to a squarewave oscillator 36 and a secondary winding which is connected through the filter arrangement of diodes 38, 39 and switch 42 to amplifier 17. In operation a monostable circuit 46 is set on receipt of a squarewave pulse and after its set period it resets to set the monostable 47 which operates switch 42, which may be a field effect transistor, until monostable 47 resets after the elapse of the set time. The operation of switch 42 effectively rectifies the output of winding 35 so that capacitor 45 is charged up to represent the voltage across winding 35. Any jitter on the signal from winding 35 is lost in the diodes 38, 39 so that long term variations only are stored by charging or discharging capacitor 45. In a modification the capacitor is only charged from winding 35 and discharges through resistor 49 and amplifier 17 which simplifies the circuitry used, Fig: 6 (not shown).
