Title: Improvements in engine starting mechanism
IPC: F02N99/00
Filed: 1931-10-29
Abstract: 394,673. Turning-gear. ECLIPSE AVIATION CORPORATION, 545, North Arlington Avenue, East Orange, New Jersey, U.S.A. Oct. 29, 1931, No. 30039. Convention date, Nov. 4, 1930. [Classes 7 (iv) and 7 (v).] In an electric starter, a manually-operated switch 109, when moved in one direction, closes the circuit of the starting motor 59, and movement in the opposite direction first causes the breaking of the motor circuit and afterwards the engagement of the clutch member 36 of the starter with an engine member 37 and the actuation of auxiliary ignition means for assisting in starting the engine, the closure of the starting circuit and the operation of engagement being controlled by electromagnetic means 70. As shown, the starter comprises a flywheel 12'driven from the motor 59 through a clutch 62 threaded upon the armature shaft 60 of the motor. The clutch member 36 is driven from the flywheel 12 by means of a pinion 16 on the flywheel shaft, pinions 17, 22 on a bell-shaped member 18, and an internallytoothed gear 23 integral with a sun pinion 27. Planet wheels 28 rotatable on the end of a barrel member 26 mesh with the sun pinion 27 and with a fixed internal gear 29. The barrel 26 is connected through clutch plates 39 to a nut 40 engaging a threaded shaft 46 on which the driving member 36 is longitudinally splined. The flywheel 12 can also be set in rotation manually by means of a cranking shaft (not shown) driving a bevel gear 53 on a shaft 25 integral with the barrel 26. The rod 50 for effecting engagement of the clutch member 36 with the engine member 37 is connected to an arm on a rock shaft 84, on the upper end of which is mounted a bell-crank 82 ; this is connected by a link 81 and a lever 78, Figs. 1 and 2, to the plunger rod 74 of the electromagnet 70. The coils 72, 73 of the electromagnet act upon cores 75, 76 carried by the rod 74 and movable between fixed polepieces 75a, 76a. Springs 90, 91 normally maintain the rod 74 in the central position shown. The electromagnet is controlled by the manually-operated doublepole switch 109, the plunger of which carries discs 115, 116 adapted to engage contacts 110 .. 113 in the circuits of one or other of the coils 72, 73, as indicated in Fig. 3. When the disc 115 engages the contacts 110, 111 and switches on the coil 72, moving the rod 74 to the left in Fig. 1, the circuit of the starting motor 59 is closed by a contact member 95 on the rod 74 and the flywheel 12 is set in rotation by the motor acting through the clutch 62. When the disc 116 engages the contacts 112, 113 and switches on the coil 73 to move the rod 74 to the right in Fig. 1, the motor 59 is switched off, the clutch member 36 is moved into engagement with the engine member 37, and the primary winding of an auxiliary ignition coil 153 having a vibrator 159 receives current through a conductor 162.

Title: Liquid injection apparatus for use with balers
Inventor: BARNES EDWARD
IPC: A01F15/08
Filed: 1969-06-17
Abstract: 1281086 Baling machines BP CHEMICALS INTERNATIONAL Ltd 6 Aug 1970 [17 June 1969] 30576/69 Heading B5F [Also in Division F1] Pumping means are provided in the ram head 1 of a baler for injecting liquid additives into the bale of hay or straw when it reaches a predetermined length. In the embodiment shown, the pumping means comprises a piston 2 biased forwardly of the ram head and reciprocable in a cylinder 3 connected by line 4 to liquid supply vessel 6, and via ports 9 and space 10 to injection nozzles 11 in the front face of the ram head. A valve 7 in line 4 is electrically or pneumatically controlled by a sensor 8, such that when the bale reaches the required length, valve 7 is closed and liquid in cylinder 3 is discharged into the bale. When valve 7 is open, the flow resistance through line 4 is less than that through ports 9 so that liquid passes to and fro between cylinder 3 and vessel 6. In Fig. 2 (not shown), the pump piston is actuated by an air motor with its piston spring-loaded for the suction stroke, check valves being provided in the pump suction and discharge lines. The motor is controlled by a first valve in an air supply line which is opened each time the ram head compresses material into the bale, and a second valve between the first valve and the air motor which is operated by the bale length sensor when the predetermined bale length is reached, to momentarily change over the air motor connection from the air supply line to an exhaust line. The pump then performs a suction stroke, and on the next operation of the first valve performs a discharge stroke, and remains at the end of its discharge stroke until the second valve is operated again. The quantity discharged may be controlled by an adjustable stop in the air motor cylinder.

Abstract: 1,044,067. Frequency discriminators. RANKBUSH MURPHY Ltd. Aug. 4, 1964 [Aug. 2, 1963], No. 30718/63. Heading H3A. F.M. signals are demodulated by applying them at 21, 22 in push-pull to the parallel connected bases of two pairs of complementary type series transistors 14, 13, and 16, 15 with a capacitive impedance 18, 19 connected between their connected emitters, which is charged and discharged, alternately with opposite polarity on each side, by the alternately conductive transistors of each pair, the demodulated signal being derived across a common collector load or filter 38-40 in series with the transistors. The two anti-phase inputs may be applied through emitter-followers 23, 24. Diodes 31, 32 shunted by capacitors 33, 34 may be dispensed with or connected between the bases of each transistor pair to reduce the dead zone when neither transistor is conductive. The differential capacitor 19 equalizes and balances stray capacitance and differences in alpha of the transistors. Resistors 35, 36 may be connected between the capacitor 18 and the emitters to reduce current peaks and may have inductors in series with them. A common collector impedance may also be inserted between transistors 13, 15 and earth to enable balanced push-pull output to be obtained.

Filed: 1922-11-14
Abstract: 211,212. Clossmann, J. von, and Halberstadt, H. Nov. 14, 1922. Contacts.-In switches in which damage to the normally-engaging surfaces by arcing is obviated by arranging that contact is broken at points removed from the normal points of contact, the movable contact member a, Figs. 1 and 2, moves in a circular path being secured to the arm m pivoted at m<1>. The contact a has an inner curved contacting surface and the fixed contact is divided longitudinally into two sections b, the arm m being adapted to pass down into the gap between them. The upper ends of the members b are suitably curved to conform with the motion of the movable contact-member a, the tips c being slightly flattened. The proximate edges of the forked arms are made divergent at d. In the closed circuit position shown dotted in Fig. 1, contact is maintained between thepoints on the contact-member a resting on the adjacent edges of the members b, but as the contactmember a is moved to the open circuit position as the arm m is moved through the inclined gap d the contact points between the fixed and movable members move towards the periphery of the member a where contact is finally broken at the upper position shown in Fig. 1. To maintain the contact in its normal closed circuit position against an opening spring the members b may be flattened or ramped at the normal contact surfaces or a recess h may be provided at this point. Alternatively, the rod m may be held in spring tongs k shown in Fig. 3. To prevent the rod m touching the sides of the gap between the members b insulating plates l may be provided. Other suitably shaped movable contact surfaces may alternatively be employed, for example, a cone, a cylinder, or a disc of rhomboidal form in which a continual change of contact positions is obtained during the opening movement of the switch.
