Title: Ink jet printer
IPC: H04N1/23
Filed: 1974-05-01
Abstract: 1438069 Ink jet printers INTERNATIONAL BUSINESS MACHINES CORP 1 May 1974 [22 June 1973] 18994/74 Addition to 1426803 Heading G4H In liquid-droplet recording apparatus, droplet charge is detected to control the relative timing of a clock-driven counter. An ink jet printer includes a transducer 15 for vibrating a nozzle 14 to produce droplets, a charging electrode 16 for varying deflection of the droplets in an electric field between deflecting electrodes 18, and means for controlling the phase relation between the transducer 15 and the charges applied to the electrode 16 comprising: circuit means 28, 29, 30 connected to the charging electrode 16 for applying, in response to an initiation signal, input information signals to the droplets and, in the absence thereof, applying a calibration signal to droplets to be discarded; a counter 31 cyclically counting clock pulses 25 and producing the initiation signal during each counting cycle; means 20 for catching the discarded droplets having a plurality of impact locations 20a, 20b and producing output signals indicative of the location; and means responsive to the output signals to alter the number of clock pulses fed to the counter 31 and change the time of the counting cycle and thereby the initiation signal. Contacts 45 in location 20a are connected across capacitor 50 and resistor 49 in a filter 47, whereby ink droplets in location 20a complete the circuit and provide a low impedance path to ground for the filter output. Ink droplets in location 20b produce no such action. Comparator 51 produces a 0 or 1 output for droplets in locations 20a, 20b respectively. Normally, irrespective of where the droplets land, counter 31 is driven by clock pulses 25 via path 33 or 34 and AND 36 or 39 according to the output of comparator 51 which thus makes no difference. However, whenever a sampling signal is produced at 69 in response to 62 &c. (see Fig. 1), an extra pulse is produced by single shots 70, 71 and fed to the counter 31 via AND 36 if the output of comparator 51 is 0 whereas if the output of comparator 51 is 1, counter 31 receives one clock pulse less due to the influence of the sampling pulse on NAND 53 since now clock pulses reach the counter 31 only via AND 39. The initiation signal for character generator 28 and discard waveform circuit 30 is the reset output of counter 31, the time position of which is thus varied. Driver 29 passes the discard waveform from 30 only in the absence of output from the character generator 28. There is one initiation signal per droplet since the capacity of counter 31 equals the division ratio of divider 26 shown, viz. 8.

Patent GB-459168-A (GB)
Title: Improvements in or relating to gas fired ovens or furnaces
IPC: F23N1/00
Filed: 1935-07-03
Abstract: 459,168. Fluid-pressure servomotor-control systems. GUNSTON, D., and BAKER PERKINS, Ltd., Westwood Works, Peterborough. July 3, 1935, No. 19036. [Class 135] [See also Group XI] In fuel-controlling means for the burners of bakers' or like ovens which are heated by the circulation of the products of combustion, a master control valve 21 is provided in the fuel supply to a manually actuable cock 19 and is operated by the pressure of the fuel, which pressure is made available and maintained available for said operation only upon the establishment and continuance of a supply of current tor operating the circulating means. The master valve 21 tends to close by gravity and is opened or maintained open by the pressure of the gas supply acting on the underside of a diaphragm 56 by way of a pipe 59 and cock 60 from the supply side of the valve or by way of a pipe 32 and cock 33 from the outlet side of the valve. In order to ensure the correct order of operation the manually actuable cock 19 has a cam 40 engaging a cam 41 on the arm 34 of a pilot jet 35 and preventing the opening of the cock 19 until the jet has been moved into a position to light the main burner 15. The cam 41 also engages a cam 42 on the cock 30 of the pilot jet so that the cock 30 must be opened before the arm 34 can be moved. As an additional safeguard the pilot jet 35 is retained within a hood 36 by a locking device 37 which is released by a thermostatic strip 38 after the jet has been lit. A thermostatically controlled valve 20 is included in the main gas supply pipe 18 and both valves 19 and 20 are operatively connected to valves 24 and 26 respectively, in an air intake conduit 23. In operation, in order to start the heating system, a lever 61 is actuated and this opens the cock 60, closes a switch 62 which operates a relay to close the starting switch 66 of the fan or circulator and opens an inlet 17 for washing or scavenging air. The opening of the cock 60 allows gas pressure to build up beneath the diaphragm 56 and so open the master valve 21 and also allows a gas supply to pass to the pilot jet by way of a pipe 31. As soon as the fan motor starts current is supplied to an electromagnetic device 64 which opens the valve 33 and allows gas to pass to the diaphragm chamber from the outlet side of the master valve so that the valve remains open after the release of the lever 61 and the consequent closing of the cock 60. The burner is then ignited by actuating the cock 30, arm 34 and cock 19 as previously described. If the motor fails the valve 33 will close, the gas beneath the diaphragm will leak away to the pilot jet and the valve 21 will therefore close and cut off the gas supply. In order to reopen the valve 21 the cock 19 and arm 34 must be moved back to starting position so that the cock 30 may be closed to allow pressure to build up in the diaphragm chamber when the cock 60 is again opened.

Title: Improvements in and relating to electric asynchronous machines
IPC: H02K17/28
Filed: 1923-07-25
Abstract: 223,657. Ellis, G. B., (Sachsenwerk Lichtund Kraft-Akt.-Ges.). July 25, 1923. Alternating-current commutator machines.-An asynchronous machine having primary and secondary windings has an additional phasecompensating winding inserted within the same slots as the primary winding, and connected with a commutator, the secondary winding being closed by the compensating winding through a single set of brushes stationary relatively to the secondary part. The primary winding a, Fig. 1, on the rotor is inductively coupled with the compensating winding c connected to the commutator e from which current of slip frequency is led into the stator secondary b. In order to avoid opening the secondary circuit or short-circuiting the compensating winding when the starter f is disconnected and the switch g closed, the starter may be arranged in series connection with the secondary and compensating windings, for example, as shown in Fig. 2. It is stated that, theoretically, the effect of the compensating voltage is a maximum if the brush position is selected so that the vector of this is at right angles to, the vector of the slip voltage, and zero when the brushes are displaced 90‹ from this position. If a value of compensating voltage be chosen such that complete compensation at full load is obtained with the most favourable position of the brushes, the motor will be, overcompensated at light loads and under-compensated at overloads. According to the invention, the compensating voltage is selected essentially higher than (approximately double) the voltage which is required in the foregoing case, and a brush position to give complete compensation at all loads is deduced from a set of curves as shown in Fig. 4 which represents power factor plotted against brush displacement for different loads. Various arrangements of the commutator winding for ensuring limitation of the compensating voltage are described in the Specification.

Title: An improved installation and process for treating dustcontaining mixtures of substances of different densities
IPC: B07B4/02
Filed: 1945-07-26
Abstract: 609,029. Centrifugal machines. POITTE, F. July 26, 1945, No. 19207. Convention date, July 1, 1944. [Classes 23 and 117] Apparatus for separating a mixture of two substances of different density particularly coal and slate comprises a hopper 3 feeding the mixture through a metering device 4 and chute 5 on to a rotating disc 6 which spreads the mixture uniformly into an ascending air current produced by the fan 8. Heavy particles of both substances fall out through outlet 17 where volumetric sifting in a vibrating sieve 18 removes the smaller sizes of the higher density substance, slate. Small particles are carried upwards by the air current through the openings between the movable vanes 12 into the outlet 13. Centrifugal action caused by the vanes 12 enables larger particles in the suspension to drop into the cone-shaped part 11 and when a sufficient quantity has accumulated flaps 14 open to discharge the contents back into the air stream. Small particles in suspension passing out through conduit 13 are fed into a conventional cyclone separator 19 where they are deposited and fed through a chute 21 to a second apparatus similar to that described above. Volumetric sifting by the sieve 30 retains only the lighter density substance, coal. In various modifications the second apparatus comprises a cyclone separator which may be incorporated with a centrifuging spiral.

Title: Improvements in or relating to lifting means for example for bales
Inventor: BOOTH KEITH
IPC: A01D87/12
Filed: 1963-05-15
Abstract: 1,008,076. Bale lifting attachments for tractors. MIDLAND INDUSTRIES Ltd. May 7, 1964 [May 15, 1963], No. 19223/63. Heading B8H. When the loader arms 19, Fig. 2, of a tractor are raised, jaws 24 of a bale gripper are closed by a sub-frame 15 which is swung up about pivot pins 21 on a main frame 10. The subframe 15 is attached to the ends of levers 25, rigid with the jaws 24, by pivoted links 26. The bales are raised when the closing movement of the jaws is arrested by the bales being gripped. Tie bars 40 maintain the loader in the correct orientation during lifting. A latch 42 engages a pin 46 to prevent relative movement between the sub-frame 15 and the main frame 10 so that the loader can be lifted with the jaws open after a load has been set down. A cable 47 connected to a handle within reach of the tractor driver releases the latch to permit the jaws to be closed. In the event of the latch being disengaged when there is no load between the jaws 24, a stop peg 44 on the latch abuts a bracket 43 so that the jaws are only permitted to close by a small amount. Bars 32, Fig. 3, may be attached to the jaws 24 by bolts 51 and brackets 33 so that smaller bales may be lifted.

Title: Method and apparatus for mechanically producing string-tied bags
IPC: B65D33/28
Filed: 1966-05-02
Abstract: 1,104,890. Draw string bags. A. MEYER. 2 May, 1966 [8 May, 1965; 12 Jan., 1966], No. 19246/66. Heading B8K. [Also in Divisions B5 and D1] Draw string bags are formed from two superimposed webs, each having a longitudinal hem containing strings by transversely cutting the webs but not the strings to form a bag, which is accelerated forward to separate it from the webs so that the strings therebetween can be severed and knotted. As described, a longitudinal edge 10a, Fig. 1, of a plastics tubular sheet 10 is slit by a blade 13 and the marginal edges folded over to form hems 24, the upper and lower hems containing a pair of strings 17, 18 and 19, 20 respectively. A partial weld (42a, 42b) (Fig. 2, not shown), is formed by a welding bar 26 between each pair of strings and the hems sealed to the sheet 10 at (43a, 43b) by a welding bar 27. The sheet 10, but not the strings, is then transversely sealed and severed by a welding bar 31 to produce a bag 36 which is gripped by an accelerating mechanism 32, driven at a higher speed than the preceding sheet 10 in order to draw out the strings between the bags 36. Finally, the strings between the bags 36 are cut at 37 and subsequently knotted. The strings 18, 20 and 17, 19 (Fig. 2, not shown), may be knotted to each other by the apparatus illustrated in Fig. 4. The pair of strings 162 are drawn apart between adjacent bags on a conveyer belt 161 passing between guide rollers 159 and 160 (not shown on the left-hand side of the Figure). On the movement of a driving lever 112 in the direction g, the guide rollers 159 and 160 are moved to cause the strings 162 to be lowered on to projections 132 of slide members 123 and 124, into slots 146 of string guides 145 and on to the recesses 148a and 149a of tying tongs 148 and 149. The strings 162 are clamped on a support 111 by brackets 119 and 120, between which they are cut by a blade 121. During the further movement of the lever 112, the slide members 123 and 124 are moved forward by disengagement of pawls 137 and 138 so as to tightly clamp the strings (Fig. 5, not shown), whereupon the tying tongs 148 and 149 are rotated by a worm shaft 150 to form a loop (168) in the strings 162 (Figs. 6 to 8, not shown). Finally, the loop (168) is pushed off the tong by an ejector arm 174 thereby forming a knot.
