Filed: 1942-11-09
Abstract: 562,031. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 9, 1942, No. 15821. Convention date, Nov. 12, 1941. [Class 38 (iv)] [Also in Group XXXVII] A thermal switch for starting an electric discharge lamp 3 has a heater 27 arranged across its contacts 14, 15, the heater serving to bring the contacts into engagement and then being short-circuited by them so that an interrupting action ensues in which each "break" causes a voltage surge tending to start the discharge between the electrode 2 of the lamp ; should the lamp not start after a certain number of attempts, a second heater 25 which is fully energized each time the contacts close and so gradually raises the temperature of a metal block 19 carrying one of the bimetallic strips 17, causes the contacts to remain permanently closed. On the other hand, should the lamp start, the reduced voltage across the heater 27 and a saturable reactor 28 is insufficient to cause the contacts to re-engage and they remain open. The contacts 14, 15 are mounted on two bimetallic strips by means of intermediate strips of low conductivity, e.g. of stainless steel, and in the form shown the strip 16 serves to compensate for variations of ambient temperature while the coils 27, 25 both heat the strip 17. In a modification, the coil 27 heats the strip 16 and the coil 25 the strip 17, and the strips both move towards each other when heated.

IPC: G03G15/30
Filed: 1961-05-02
Abstract: 978,812. Electrophotographic copying apparatus for use with heat sensitive copy material W. ZINDLER, [trading as LUMOPRINT ZINDLER KOMM.-GES.]. May 2, 1961 [May 11, 1960], No. 15869/61. Headings G2C and G2H. In an electrophotographic copying apparatus comprising guide means for moving an electrophotographic coating on a backing successively through a charging device for electrostatically charging the coating and an exposure device for forming a latent electrostatic image in the coating. further guide means are arranged to guide a copy sheet in contact with the electrophotographic coating past a heat radiator disposed immediately after the exposure device along the path of advance of the electrophotographic coating and having a black filter, the heat radiator serving to produce an image in heat sinsitive substances on the copy sheet in accordance with the differences in the heat conductivity of the electrophotographic coating caused by the formation of the latent electrostatic image. As shown, the device comprises a transparent cylinder 5 rotatably mounted on spring urged or resilient rollers 8, 9 and supporting an electrophotographic layer 7. The cylinder is rotated by means of a further spring-urged or resilient roller 10 connected by belt drive 43 to a motor 42 so as to guide the layer 7 successively past a charging station 41, an exposure station 14 and into contact with a roller 6 enclosing a heat radiating lamp 27. The roller 6 is formed of black glass and is resiliently urged into engagement with the layer 7 by spring-urged or resilient rollers 29, 30. On feeding an original sheet into opening 19, it is transported between rollers 10 and 22, past the station 14 where the layer 7 is reflexly exposed to produce a latent electrostatic image thereon and is finally ejected from the device through exit opening 20. As the original sheet passes between rollers 23 and 11, the roller 23 is displaced radially or roller 11 sufficiently to engage a copy sheet which was inserted into opening 24 at the same time as the original was inserted into opening 19 and which was for a time retained in the nip between the roller 23 and a sprung end part of a guide member 25. The heat sensitive copy sheet (such as is disclosed in Specification 978,811) is thereby fed past the heat radiator 27 in super-position with the latent electrostatic image on layer 7. The copy sheet which now bears a visible image is ejected through an opening 36 into a tray 35. Switches such as 40, 55 in the path of the copy sheet may be provided for actuating the lamp 27. Members 15-17, 10, 22 and 23 are constructed in a light-tight manner to restrict light from lamps 45, 46 to the region of the exposure station, the light-tight arrangement of roller 22 and guide member 16 being shown in Fig. 5. Ventilating holes 4 are provided in the base of the cabinet 1. An alternative construction of the guide channels 19, 20, 24 is illustrated in Fig. 2-not shown.

Abstract: 288,991. Wayne Co., (Assignees of Brandt, W. F.). April 18, 1927, [Convention date]. Fixed-chamber apparatus; varying quantity measured.-In a liquid-measuring and delivering device, the quantity of liquid to be delivered is determined by a reciprocating member, having a lug thereon, and variable-quantity stops each of which is adapted to be rotated about a horizontal axis into and out of the path of travel of the lug. Fig. 2 shows part of a petrol pump the measuring vessel of which is filled by a pipe F and is emptied by a serve pipe d, Fig. 7, vertically adjusted in a well pipe E by means of rack R and gearing h. The rack R is attached to guides r-r<3>, which move on a guide rod G; on the uppermost) guide r<3> is a lug r<4> which contacts with the stops a<22>, a<30> &c, near the rack R. There are shown ten stops a<22>, a<30> &c., each corresponding to a different number of gallons to be delivered. These are, operated by means of levers a<2> &c., Fig. 5, bearing numerals, and arranged outside the casing P, so that when one of the levers a<2> is turned, it shows the number of gallons to be delivered by means of a numeral in an erect position. If it is desired to deliver ten gallons, the lowest stop a<30>, the operating-lever of which bears the numeral 10, is turned to the position shown, so that the lug r<4> is stopped in the lowest position, and the serve pipe, which is attached to and moves with the, guide r, is stopped in the lowest position, and delivers ten gallons. The stops a<22> - - a<30> are adjusted by screws a" - - a<40>, and are secured after calibration by sealed wires W. A dent and spring-pressed ball fitting a<42>, Fig. 5, keeps each stop a<30> in either its upper or its lower position. In reaching the uppermost position, the lug r<4> pushes back a spring latch K, and passes over it, rotating an indicator lever k, Fig. 5, so as to show, outside the casing P, the word " Fill " in an erect position. The rack is freed by turning the lever k, the pin k<3> on it withdrawing the latch K against the pressure of the spring k<5>. In the uppermost position of the serve pipe D, Fig. 7, it contacts with a flat valve d, causing the lever f<5> to open a spring valve #<1> ; liquid may then be pumped on to the measuring-chamber. The apparatus is applicable to apparatus of the kind with a vertically adjustable drain-back or overflow-pipe, as well as the visible-level apparatus with the vertically-adjustable serve pipe shown.

Abstract: 1495789 Hydrostatic transmission control CATERPILLAR TRACTOR CO 18 April 1975 [20 June 1974] 16138/75 Heading F2W [Also in Division G3]  In a hydrostatic transmission for an earth moving vehicle wherein a variable displacement swash-plate pump 12 in closed circuit with a fixed displacement motor 18 has its displacement varied by spring centred servos 43, 49 supplied with pressure liquid from a manually controlled follow-up servo valve 42, means 136 responsive to the pressure differential in the main and return lines 19, 21 act on the servo valve 42 to override the manual control and reduce pump displacement when the pressure differential exceeds a predetermined value. The follow-up servo valve 42 comprises outer and inner valve spools 64, 86 respectively biased to their central neutral positions by springs 78, 99. A manual control lever 39 acts through a linkage 113 to move the outer spool 64 left or right for forward or reverse drive respectively. Movement of the outer spool 64 supplies pressure liquid from a pump 33 through a line 54 or 48 to the servo 49 or 43 which increases pump displacement in a forward or reverse direction. The movement of the swash-plate 22 is fed back through a linkage 118 to return the outer spool 64 towards its central neutral position. The outer spool returns to a position in which it maintains a small flow through the follow-up valve sufficient to make up the pressure loss through a fixed throttle 112 between the servo supply lines 48, 54. A variable throttle inching valve 62 is provided between the pump 33 and follow-up servo valve 42. The pressures in the working circuit lines 19, 21 act through ducts 142, 138 and plungers 139, 137 on a plate 111 fast with the inner valve spool 86. When, on overload, the pressure differential between the lines 19, 21 exceeds a predetermined value the inner valve spool 86 is moved against the bias of the spring 99 and supplies pressure liquid through the lines 48, 54 to the servos 43, 49 to reduce pump displacement. The follow-up linkage 118 moves the outer valve spool 64 to follow the movement of the inner spool. When the overload is removed the inner spool returns to its initial position and the pump the swashplate is returned to its manually selected position. In Fig. 4 (not shown) the manual control and follow-up linkages are connected to the inner valve spool and the override means to the outer valve spool.

Abstract: 997, 047. Light intensity measurement. MULLARD Ltd. Jan. 10, 1964 [April 26, 1963], No. 16531/63. Heading G1A. [Also in Division G2] A light intensity measuring device which may be used as a photographic exposure meter comprises a circuit giving an indication only when the input exceeds a certain value. A photo-sensitive device is connected to the circuit input and adjustable means provided to vary the level of the input signal it applies thereto. The Provisional Figure shows a cadmium sulphide photo-resistor 1 connected in series with a resistor 2. The junction between them is coupled through an inductor 5 to the base electrode of a PNP transistor 6 whose collector electrode circuit includes a transformer 9 magnetically coupled with inductor 4. The secondary of the transformer feeds a neon indicator 11 although this may be replaced by a relay or meter. When the potential on the transistor base electrode is below a predetermined value the circuit oscillates causing the neon to glow. The circuit may be adjusted by varying the resistor 2 or adding further resistors in series or parallel with photo-resistor 1. It is set up to oscillate for all light intensities above a relatively low value and light intensities above such a value are measured by inserting an optical wedge or opaque shutter to reduce the light falling on the cell until the neon just ceases to glow. The position of the optical attenuator then indicates light intensity. In a modification, instead of using an optical attenuator, resistor 2 is made variable and adjusted from a predetermined value to neon extinction point to determine light intensity. A lens may be placed in front of the photo-sensitive element and the circuit can be adapted for photo-voltaic devices. The optical attenator or variable resistor control may be coupled to adjust the aperture and/or exposure controls of a camera.
