Title: Improvements in driving mechanism for mechanical stokers
IPC: F23K3/10
Filed: 1929-10-30
Abstract: 341,579. Mechanical stokers. RILEY STOKER CORPORATION, 9, Neponset Street, Worcester, Massachusetts, U.S.A. Oct. 30, 1929, No. 32942. Convention date, Nov. 5, 1928. [Class 51 (i).] In a driving mechanism for mechanical stokers of the kind in which the connection of a continuously running driver to a driven member is effected periodically by means of a traveller in such a manner that the time intervals between the periodic connections may be varied by controlling the movement of the traveller, the time intervals are varied by varying the stroke and speed of movement of the traveller. Fig. 1 shows the invention applied to a fuel feeding ram driven by a continuously rotating gear wheel 39, crank shaft 35 and connecting-rod 34, the gear wheel 39 being connected to the crank shaft at intervals by a clutch member 38 as described in Specification 145,499, [Class 51 (i), Furnaces and kilns, Combustion apparatus of]. The clutch release lever 53 is pivoted to a bracket 59 and urged away from the clutch by a spring 60, its outward movement being limited by a set screw 61. The lever is held in clutch releasing position by a latch 63 which is released at predetermined intervals by a traveller 67 sliding in bearings 68, 69. The lowermost position of the traveller is adjusted by a cam 70. The traveller 67 is advanced gradually upwards to lift the latch by a friction disc 80 engaged by the arm 82 mounted on a rotatable shaft 83 which also carries an arm 86 located in the path of a roller 87 on the rotating gear wheel 39. The lever 82 rests by gravity on a pin 89 adjusted by a cam 90. To prevent the traveller from dropping back after each upward movement a second friction disc 93 is provided which rests against a flange 94 on the pin 89 which controls the extent of oscillation of the arm 82 and the rate of upward advance of the traveller. After the latch has been tripped, the traveller is returned to its lowermost position by a member 95, secured to a rod 98 and extending beneath each disc. The rod 98 rests on a lever 102 pivoted at 103 and connected by a link 105 to the clutch release lever 53, which during release actuates the lever 102 and release member 95, the latter then lifting the discs 80 and 93 and allowing the traveller 67 to fall. The lever 53 is returned to its original position by a cam 107 attached to the clutch collar 38 and adapted to strike the lever 102 and through the link 105 return the clutch lever into a position where it is retained by the latch 63. The adjusting cams 90, 70 may be operated automatically by boiler pressure. Specification 248,310, [Class 51 (i), Furnaces and kilns, Combustion apparatus of], is also referred to. In the Specification as open to inspection under Sect. 91 (3) (a) the invention was described and claimed broadly, but in the Specification as accepted the invention is confined to mechanical stokers.
Patent GB-396982-A (GB)
Title: Improvements in automatic apparatus for preparing hot beverages such as tea, coffee,cocoa and the like
IPC: A47J31/22
Filed: 1932-11-22
Abstract: 396,982. Tea - making apparatus. VIRMANI, J. D., c/o Bombay Radio Co., Ltd., opposite Marine Lines Station, Bombay, India. Nov. 22, 1932, No. 33011. [Class 129.] Apparatus for making tea, &c., at a predetermined time comprises two compartments, one for water and one for milk, an electric heater, a time switch and means for lowering the tea leaf, &c., container into the boiling water and for allowing the tea, &c., and milk to run together into a cup. In operating the apparatus, the time switch 9 is set and the cup 46 placed on the platform 46a. The weight of the cup depresses the platform to make contact between 4, 6, as shown in the Figure. A wall plug 1, 17 is plugged into its socket and the double pole switch 2, 16 turned on. If it will be dark at the time the beverage is required, the switch 49 is thrown over to 50. As the time switch 9 operates, the current is turned on passing from the lead 1 to the switch 2, the fuze 3, contacts 4, 6, time switch 7 to 10 and on through resistances 18, 19 and resistances 21, 20. The current returns through 11 to the contact 12, through the ballhead 13, to the contact 14, fuze 15, switch 16 and main plug 17. When the resistance value of 18, 19 is equal to that of 21, 20, no current will flow between 25, 22. This bridge is set slightly out of balance by the arm 22 of the potentiometer 21, 22 so that a small current constantly passes through the resistance 23, 24, This current is insufficient to heat the element 26 but to bring it to almost a critical point at which it just starts bending so that if the temperature of the coil 23, 24 increases due to increased current, 26 will bend and make contact 27. Resistance 19 is made of bismuth and forms the heater element of the container. As this resistance heats up, its resistance alters, disturbing the balance of the bridge and allowing more current to flow. As soon as 26 touches 27, the current flows from 1 via 4, 6, 27, 26 to the solenoid 28 to cause the handle 13 to be jerked downwards to immerse the tea leaf in 29 into the boiling water. This breaks the electrical connection between 12, 14 to stop the current through the heater. When the container 29 drops into the boiling water, the ball-head 13 makes contact between the members 30, 31 to cause current to flow into the coil 32 to heat up the element 34 to make contact with 35 and so actuate the solenoid 36. This pulls the plunger 37 to turn the cock 41 against the spring 40 to deliver the tea and milk into.the cup 46. The quantity of milk is regulated by the valve 44. As the cup fills, its weight causes 4 to make contact with the insulator 7, so breaking the contact 4, 6 and interrupting the flow of current. The member 4 goes a little beyond 7 to make contact 8 to ring a bell.

Filed: 1963-08-22
Abstract: 1,040,262. Stencil switches. R. L. WALKER. May 22, 1964 [Aug. 22, 1963], No. 33229/63. Heading H2B. [Also in Division G5] A record tape operable switching device comprises a tape thickness gauging means and at least one switching means capable of being influenced by the passage through the gauging means of one or more discrete zones of a tape having a greater thickness than other parts of the tape. The tape is provided with adhesive strips at desired points, these strips being longer than normal splicing strips and either extending over only half the width of the tape (Fig. 3, not shown), or being of trapezium shape (Fig. 3A, not shown), so that they are only effective for one direction of tape feed. As shown in Fig. 5, the tape passes between a guide 26 and a rotatable sector 28 spaced from the guide so that tape of normal thickness does not touch the sector. An adhesive strip of one length will cause the sector to rotate and cause a cam 31 to close a micro-switch 38, which may operate a slide changer. An adhesive strip of a second length will cause the sector to rotate further and cause a second cam 32 to operate a second microswitch 38A, which may stop the tape recorder. A normal splice will rotate the sector, but not far enough to operate the switches. In a modification, Fig. 9 (not shown), the sector is coupled by a lost-motion coupling to a separate cam disc so that the time for which the switch remains closed is less dependent on tape speed. In further modifications, Figs. 12-20 (not shown), rotation of the sector by a predetermined amount causes a resilient roller to engage the tape and be driven for one revolution before the sector is allowed to return to its rest position.

The cams 13, 13a are clamped into position by plates 11; the right hand cams 13 engage switches 4 which when operated initiate a rapid feed to the stationery and this continues until cam 13a, on the other side of the control disc, operates a switch 5, whereupon the rapid feed ceases and a step-by-step line feed under the control of the tabulating machine occurs. There may be several rapid feeds for each form length and the rapid feed may occur from the end of printing on one form over to the commencement of printing on the first line of the succeeding form. To accommodate for different lengths of form, a gear wheel 17 coupling the disc to the tabulating machine may be interchanged by removing the disc from the shaft 24 by undoing a thumb screw 26. After replacing the control disc or when starting to type on a new form, the disc'is aligned by engagement of a stud 32a in a notch 30 in peri-, phery of plate 28 which rotates with disc 7. The Provisional Specification states that the switches may be mounted on hinged supports.

Title: Transistor circuits
IPC: H03K19/10
Filed: 1963-08-27
Abstract: 1,005,549. Transistor and tunnel diode logic circuits. WESTINGHOUSE ELECTRIC CORPORATION. Aug. 27, 1963 [Sept. 10, 1962], No.33823/63. Heading H3T. A logic circuit comprises at least one transistor 14 having a constant current collector load comprising at least one tunnel diode 35 in parallel with a resistance 34. In the NOR circuit shown, resistances 32, 34 are respectively equal in value to the negative resistance values of tunnel diode 33, 35. The collector load 23 for transistors 14 thus has the characteristic shown at 46 in Fig. 6, with two constant current regions. Transistors 14 are normally non-conductive so that the collector voltage assumes the value at which the input characteristic 60 of the second-stage transistor 140 cuts the lower constant-current region of curve 46 in Fig. 6. When one or more of transistors 14 is made conductive by pulses at the base, the collector voltage assumes a second condition at which the transistor saturation curve 30 cuts the upper constantcurrent region of curve 46. The operation is unaffected by variations of curves 30, 60 as long as they continue to cut the respective constant current regions of curve 46. Fig. 7 (not shown) relates to a similar circuit using only one tunnel diode and resistor, giving a single constantcurrent region corresponding to the saturation condition of the transistors.

Title: Wind motors
Inventor: CHILMAN JOHN ALFRED
IPC: F03D7/02
Filed: 1964-08-19
Abstract: 1,043,108. Wind motors; centrifugal pumps. DOWTY ROTOL Ltd. Aug. 11, 1965 [Aug. 19, 1964], No. 33891/64. Headings F1C and FIT. [Also in Division G3] In a fixed or retractable wind motor suitable for driving accessories in aircraft or other vehicles, the pitch of the rotor blades 13 is automatically adjusted by an hydraulic mechanism controlled by a speed governor. A reservoir 41, 42 formed within the rotor hub supplies liquid through ports 46, Fig. 3 (not shown), to a rotating chamber (45) containing a non- rotating scoop (47). Liquid is hurled centrifugally to the radially outer regions of the reservoir and chamber, and in the chamber is collected by the scoop and passed radially inwardly to a positive displacement pump (50) mounted within the rotor on the rotational axis and driven by the rotor. An annulus 61 in a spool valve 51 receives pressurized liquid from the pump via a passage 53 and a pressure relief valve comprising an axially movable sleeve (77) which in the event of excess pressure uncovers a drain port (80) to the reservoir. If the rotational speed of the rotor exceeds a predetermined value, the fly-weights 70 of a centrifugal governor move the valve 51 forwardly to communicate annulus 61 through ports 59, 62 with a chamber 64 in a hollow shaft 29 of a piston 33 in a cylinder 31, and a chamber 69 on the opposite side of the piston with the reservoir via the interior of valve 51. This causes the piston to move forwardly and rotate the blades 13, through crank-arms (not shown) connecting the blades with the shaft 29. in the pitch coarsening direction to reduce the rotor speed. Low rotor speed results in the valve 51 moving rearwardly to communicate annulus 61 through ports 60, 66, passage 67 and port 68 with the chamber 69, and the chamber 64 to drain to increase rotor speed. The predetermined rotor speed is set by a threaded adjuster for the governor speeder spring 74. Access to the adjuster is through a pull-out plug 81 having a port 85 for filling the reservoir. The blades may be adjusted to the feathered (or near-feathered) position independently of the governor by moving the valve 51 to its forward position via a rod 87, a coaxial rod 86, Figs. 3 and 4 (not shown), a bell-crank lever (89) and a rod (93) extending together with a bevel-gear-driven accessory drive shaft (26) through a fixed hollow mounting arm (20). Since the liquid discharged to the reservoir from the valve 51 and the relief valve is at an elevated temperature it prevents ice forming on the rotor hub. The rotor blades may include electrical anti-icing means powered from an alternator driven with the accessories.
