Title: Temperature and safety controls for fuel burners
IPC: F23N5/14
Filed: 1944-12-05
Abstract: 594,969. Controlling burners. MAY, P. (Robertshaw Thermostat Co.). Dec. 5, 1944, No. 24292. Addition to 594,968. [Classes 75 (i) and 75 (iii)] [Also in Groups XXIX and XXXV] In a safety ignition and control system for burners the opening of the main gas valve 16 allows gas to pass to a pilot burner 12 and closes the primary circuit of an electric transformer 22, thereby energizing an igniting coil 74 adjacent the pilot burner and a relay 59. The transformer secondary circuit also includes a ballast resistor 30 having a positive temperature coefficient of resistance arranged adjacent the pilot burner, an initially closed electromagnetic valve 18 between the valve 16 and the main burner 10, and an initially closed mercury switch 60 forming a parallel mesh in series with a second parallel mesh consisting of a constant or current sensitive resistor 36, a thermostatic control switch 39, and a constant resistance 38. After time delays of approximately 6 and 18 seconds respectively the relay 59 breaks a mercury switch 62 in the ignition coil circuit and the mercury switch 60. If the pilot burner has by then ignited thereby heating the resistor 30, and the bimetallic arm 40 of the thermostat 39 is in engagement with the " cold " contact 46 sufficient current passes through the valve 18 to open it to allow gas to pass to the main burner for ignition by the pilot burner. As the ambient temperature increases the bimetallic arm 40 leaves the " cold " contact 46, a sufficient current passing through the valve 18 to hold it open until the engages the " hot " contact 42 which is connected to a resistor 52 to form a shunt to the valve circuit. The valve 18 then closes until the arm 40 again engages the " cold " contact 46. The " cold " contact 46 may be mounted on a bimetallic arm 44 which becomes heated by the current passing through a coil 47 to the resistance 38 so as to flex away from the arm 40 the movement of which is limited by a stop 48. A cut-out 58 such as a slow-acting bimetallic switch opens the circuit of the valve 18 if the ballast-resistor 30 becomes open circuited. Specifications 572,130 and 594,994 are referred to.

Abstract: 1381572 Weighing machine MURRHARDTER WAAGENFABRIK Gebr SOEHNLE 24 May 1973 [17 Feb 1973] 24930/73 Heading G1W A personal weighing machine indicates the weight of a person and the deviation of his weight from his optimum weight according to his height. In Fig. 1, a pair of height scales, 6 for women and 6' for men, are provided alongside a radial cut-out over-lying the disc 7 carrying the weight indicia 3 which co-operate with a fixed pointer 4. The disc 8 carries an annular scale for each height category, each annular scale having portions of different colours so that for a given height category, the colour showing in the cut-out is an indication of the weight deviation from optimum weight. In Fig. 3, a series of height scales for different classes of persons are carried on the faces of a pair of prisms 10, 10'. Each prism has 3 or 4 faces, is rotatable by means of a wheel 11, 11', and is held in a desired position by a detent mechanism Fig. 8 (not shown). Associated with each height category is a weight deviation scale Fig. 5 (not shown) provided on the disc 7, carrying the weight indicia and viewable through a window 13 between the prisms 10, 10'. A rotatable mask 12 is provided above the disc 7, and has a series of windows 13 Fig. 4 (not shown), there being a window 13 for each height category. The windows 13 are angularly spaced such that only one window at a time may be positioned between the prisms 10, 10'. The weight deviation scales may also employ graduated colouring. In Fig. 10, the weight indicating disc has a weight deviation indicating line 8 2  which co-operates with a weight deviation scale 18 carried by a slider 19. The slider 19 has a rack 24 meshing with a pinion 23 rotatable by a knob 22. A wheel 5 is coupled to knob 22 by a brake means, and carries a height scale 62 co-operating with a fixed pointer 21. The position of knob 22 relative to the wheel is adjusted using scale 25 and pointer 26 according to sex and build as indicated by a chart 27, and then wheel 5 is rotated until the correct height is indicated on scale 6 2 . A brake means is provided for the wheel 5. In a further embodiment, height scales are provided on sliders.

Filed: 1961-07-10
Abstract: 972,709. Hydraulic transmission and control. GESELLSCHAFT FUR LINDE'S EISMASCHINEN A.G. July 10, 1961 [July 9, 1960], No. 24942/61. Headings F2C and F2D. [Also in Division G3] An hydraulic power transmission system comprises a swash-plate pump 1 driving a motor 5 in which the inclination of swash-plate is varied by a servomotor 11 in response to manual means or the pressure in the transmission system. The servomotor 11 comprises a piston 33, one side 24 of which is subjected to the fluid pressure fed from a line 23 while the other side 42 is connected to this pressure or exhaust through a passage 41 controlled by a pilot valve 31, a land of which co-operates with a groove 40. The supply at 24 passes through passages 34, 35 and 36 to act on piston members 37, 38, the piston 38 being twice the area of piston 37 whereby the piston 38 and hence the pilot valve 31 is normally urged into contact with a manually adjustable cam 29. Rotation of this cam varies the inclination of the swash-plate from a zero output to a maximum output in either direction, a portion 43 of the cam ensuring zero output irrespective of any lost motion in the linkage from a control lever 25 to the cam. The pilot valve 31 is also adjustable through a lever 55 in response to pressure in the system. The lever is movable in response to movement of a member 53 which is moved by transmission pressure acting on a plunger 49 when this pressure overcomes the spring loading 56. An overload adjustment is also provided by a valve 58 subjected at one end to transmission pressure, which moves against spring 60 when the pressure exceeds a predetermined value and allows the transmission pressure to pass by passage 61 to act on two pistons 62, 63 thus increasing the force on the member 53.

The member 2 is connected by a link 3 to a lever 4 freely pivoted at 5 and actuated by an abutment 14 on a freely pivoted lever 13 actuated by the accelerator pedal 18. The idling position of the lever 4 is set by the stop 7 carried by a lever 8 connected by a Bowden cable 9 to a member 33 rotatably connected to the knob 12 but non-rotatably held in a slidable but non-rotatable member 26 in which the knob 12 is screwed. The member 33 is moved axially to adjust the position of the stop 7 by rotation of the knob.12, depression of which slides the member 26 axially against a spring 28 to withdraw the stop 7 and stop the engine. A notch 29 holds the knob 12 depressed if desired, and on release . the spring 28 returns the member 26 whereby the stop 7 returns the lever 2 to its adjusted idling position.
