Title: Mechanical restoring units in which actuating elements are restored  to zero position
IPC: G05G25/00
Filed: 1970-06-26
Abstract: 1314218 Spring mechanisms MESSERSCHMITT - BOLKOW - BLOHM GmbH 26 June 1970 [7 July 1969 4 Aug 1969] 31227/70 Heading F2S  A spring mechanism comprises an actuating element normally biased by spring means to a rest position determined by stops, departure of the actuating element from the rest position in a first of two opposite directions (rotational or translational) stressing one part of the spring means to provide a restoring force but not the other part, which is restrained by its stop; and in the second direction stressing the other part of the spring means to provide a restoring force but not the one part, which is restrained by its stop. In Fig. 2 the actuating element 10 is moving to the right from its rest position in which members 14 and 15 abut stop surfaces 11 thus stressing a spring 12, but not stressing a spring 13. In Fig. 3 the actuating element is a shaft 23, rotation of which in one direction stresses (via a follower pin 33) a coil spring 30 on a drum 25, a shoulder 16 on another drum 24 abutting a step 31 to prevent stressing of a coil spring 29. Rotation of the shaft 23 in the other direction stresses the spring 29, and not the spring 30. The rest position of the shaft, in which the springs 29, 30 hold the shoulders 16 against the stop 26, 31, can be adjusted by rotating a housing part 20 relative to a housing part 21. In the embodiment of Fig. 7, the actuating element is a disc (41, Fig. 6, not shown) rotatably mounted on a shaft 45 and having two rollers 43 which run on cam tracks on two levers 44 pivoted (at 47, 49) to a disc (42, Fig. 6) rigidly attached to the shaft. A leaf spring 46 connects the levers 44 and biases them against the rollers 43 to hold the disc (41) in its rest position. When the disc (41) is rotated in one direction relative to the disc (42) one roller 43 presses the associated lever 44 and associated end of the leaf spring 46 inwards while the other roller 43 runs over the cam track on its lever 44 maintaining the other end of the spring 46 stationary. To adjust the rest position of the disc (41) one lever is mounted on an adjustable eccentric pin 47. Both discs may have gear teeth on their periphery.

Abstract: 1507683 Photo-electric cutter control J W WARREN 26 July 1976 [28 June 1975 31 Oct 1975] 31487/75 and 45182/75 Heading G1A A device for controlling slicing operation, on an article the operation utilizing a rotating member, measures radiation reflected from the article as the article approaches the rotating member and genrates control signals from the received radiation. The reflected signal may represent surface reflectivity or surface area. The source may be fixed and detector mounted on the rotary element or vice versa or sources and detectors may be altimated in a resin encapsulated matrix, the matrix either being mounted for rotation with the rotary member or mounted in the direction of motion of the article. As shown, the device is for cutting constant weight slices of bacon 13 and uses a matrix of sources and detectors which measure both areas and reflectorice (to determine the amount of fat present). The detector/source matrix 12 is mounted for rotation with cutter blade 11 so that it scans across the end of bacon 13. Detector signals are used to control advance of the bacon towards the cutter. In an alternative embodiment, a single line of alternate detectors and sources, rotating with the array is used. In another alternative, a source/ detector matrix is mounted above conveyor 16 facing the end of bacon 13 and a transparent shield, mounted for rotation with the cutter, is interposed between bacon and matrix 12 to prevent detector contamination. The sources are preferably light emitting diodes and the detectors light dependent resistors, photodiodes or photovoltaic cells. The device may use infra-red or ultraviolet radiation or visible radiation modulated at 2À5-3 KHz.

Abstract: 1,134,087. Conveyers; orienting articles. CARMO A.S. 14 July, 1966 [16 July, 1965], No. 31601/66. Headings B8A and B8S. Buttons (14) (Fig. 3, not shown) are lifted by vanes 5 of a rotating drum 4 and fall into shoots 11 which direct them on to screw conveyers 7. If a button lands upside-down on the associated conveyer 7 it is deflected back into the base of the drum 4. If it lands the correct way up, it is traversed along the conveyer 7 in engagement with the edge of a fixed sleeve 10 until it reaches successive feelers 15 and 14. The latter control switches off a magnetic coupling for the conveyer in question. The feelers 14 are disposed above a clearance between the ends of the conveyers 7 and a welding electrode 12 having four respective depressions adapted to receive the buttons. The arrangement is such that each conveyer keeps rotating until both feelers 14, 15 are engaged by respective buttons. The feelers then operate to disengage the magnetic clutch of the conveyer 7 in question. This ensures that the electrode 12 carries away its full complement of buttons.

Abstract: 782,616. Operating clutches. SOLEX. Nov. 9, 1955 [Nov. 17, 1954], No. 32063/55. Class 80 (2). In an installation, such as an automobile vehicle, in which an automatic hydraulically or pneumatically controlled clutch associated with an internal combustion engine engages at a predetermined speed and in which an auxiliary device of the carburetter is actuated for starting the engine to enrich the fuel/air mixture, means are provided for reducing the pressure of the clutch controlling fluid when the auxiliary starting device is in action so that a fast idling speed is provided without the clutch engaging. As shown, a clutch 10, 45 is actuated by liquid pressure on a piston 47 from a pump 48 driven by the engine 1 which supplies liquid at constant pressure by reason of a control valve 49. The pressure on piston 47 to engage the clutch is regulated by a needle valve 52 which is controlled by a speed-responsive device 56 on the engine shaft and a by-pass orifice 54 so that the clutch can be engaged at the desired engine speed. The carburetter 2 is supplied with an auxiliary starting device 18 which, when in action, closes contacts 34, 35 of an electrical circuit to an electromagnet 31 actuating a further needle valve 59 which reduces the pressure to piston 47 for engaging the clutch. Consequently the engine speed must rise higher to produce the necessary engaging pressure. The contacts 34, 35 may be closed by a rotatable cam plate or the suction in the induction pipe may act through a diaphragm on these contacts.

Title: Improvements in the drying of printed matter by dielectric heating
IPC: F26B3/34
Filed: 1945-11-29
Abstract: 617,968. Dielectric heating. HOE & CO., Ltd., R. Nov. 29, 1945, No. 32271. Convention date, Nov. 29, 1944. [Class 39 (iii)] An electrical drying system for freshly printed surfaces comprises electrode elements arranged in two or more sets spaced apart along the path of movement of the surface, each set comprising pairs of electrodes opposed to one another about the path of movement, each pair being at the same potential, and the sets being connected across a source of high frequency energy. In an example, a sheet 11, to be printed on one or both sides, passes between printing cylinders 13, 14 and lower and upper sets of rod-like electrodes 62, 72, 67, 77, 42, 52, 47, 57 of semi-circular cross-section which are joined by arcuate connectors 66, 76, 71, 81, 46, 56, 51, 61. The electrodes 42, 52 and 47, 57 are connected respectively to an oscillator 22 by the inner and outer conductors 37, 39 of a co-axial cable 32. The electrodes 62,72,67,77 are similarly connected to an oscillator 23. Thus each pair of electrodes which face one another on opposite sides of the sheet are of the same potential and the high frequency electric field is induced between adjacent electrodes. Preferably the upper set of electrodes operate at a higher voltage than the lower set The oscillators 22, 23 are connected to power lines L1, L2 through a centrifugal switch 27 actuated by the shaft 29 of the cylinder 13 and serving to close the circuit when the printing speed is attained. To vary the electric power with the speed of the printing machine, a pilot motor 114 and a rheostat 113 which regulate the speed of the printing machine are coupled by a shaft 112 to a Selsyn or similar transmitter 111 which is electrically connected to a Selsyn or similar receiver 115 coupled by a shaft 116, couplings 119 and gearings 117, 118 to shafts regulating the output of the oscillators 22, 23. The couplings 119 e@ble one or both of the oscillators to be regulated by the receiver 115. The electrodes may be at right angles to the direction of movement of the sheet, as shown, or at an angle thereto. In a modification, electrodes are formed by a number of concentric rings of consecutively opposite potential. The dielectric heating can be increased by the use of a printing ink containing a material of high power factor, such as a soluble resin, or by the use of spray guns for spraying the sheet with, for example, a quick-drying volatile solution of a colourless resin. After heating the sheet passes through a cooling box 21 which houses refrigerating pipes 84, baffles 86, deflectors 87 and air circulating fans 88.
