Title: Energy converter means
IPC: H02K33/02
Filed: 1966-12-09
Abstract: 1,105,720. Reciprocating motor. GENERAL ELECTRIC CO. 9 Dec.. 1966 [11 April. 19661. No. 55333/66. Heading H2A. [Also in Divisions F1 and G1] A relay is used to produce both a mechanical and electrical output for use in a portable gas sampling apparatus. Relay coil portion 12a is connected to battery 20 through switch 21 and normally closed relay contacts 15, 16. When switch 21 is closed, relay coil portion 12a is energized and attracts armature 14 to break contacts 15, 16 and thereby open circuit the coil, causing a high voltage to be developed across the whole coil 12 which charges capacitor 25 through diode 26. The cycle repeats and provides a mechanical reciprocating output at 22 and a high voltage at 50, 51. The gas sampling apparatus comprises a probe unit 31 connected through tube 34 to chamber 37 which is connected through suction valve 40 to bellows 41. Bellows 41 is connected through pressure valve 43 to chamber 42 which is oscillated by link 22 to operate bellows 41, thereby sucking gas from chamber 37 into chamber 42 from where it is discharged through detector 47 which is energized by the voltage on lines 50, 51.

Title: Bale sleds
IPC: A01D85/00
Filed: 1974-12-21
Abstract: 1535510 Bale sledges DONNERFIELD Ltd 27 Oct 1975 [21 Dec 1974 25 Feb 1975] 55343/74 and 7744/75 Heading B5F  A bale sled comprises a plurality of bale compartments 41, 42, 43, 44, guides 10, 11, 12 divertable by a bale for filling the compartments in succession, and bale retaining means 16 releasable when all of the compartments are full. As shown the sled has a shoot 3 for receiving bales from a baling machine, but the front of the shoot may be lower for picking-up from the ground. Bales are received with their longer sides vertical and if required may be turned through 90 degrees into this position by a camming surface on a shoot at the front of the sled. Four or five compartments have pivoted guides biased into positions in which their heel portions 13, 14, 15 extend into the compartments. A first bale held in the shoot 3 by a drop arm 51 is released by the arrival of a second. The first is directed by the guide 10 into compartment 41 where it is joined by a second which remaining in contact with the heel 13, deflects the guide 10 into the brokenline position in which it closes compartment 41. Guide 11 now directs the third and fourth bales into compartment 42 when it is pivoted by the fourth bale to close-off compartment 42 and open compartment 43. After this is filled the first bale to enter compartment 44 raises an arm 22 which is tied 21 to a lever 17 allowing the lever to fall to the broken-line position. The lever 17 is tied 18 to a catch 19 holding a pivoted gate 16 at the rear of the compartments, the catch being released by contact between the lever 17 and the second bale in the last compartment.  Instead of operating the guides by means of heels they may be operated by an arm-and-lever system similar to that for the gate 16, particularly if a floor raises the bales off the ground. The sled may slide or run on wheels 4, 5, 6. Reference has been directed in pursuance of Section 9 subsection (1) of the Patents Act 1949 to patent no. 1,402,589.

Patent GB-558759-A (GB)
Abstract: 558,759. Ammeters and voltmeters. STANDARD TELEPHONES & CABLES, Ltd., GRACE, B. B., HANDLEY, J., and GILLIVER, G. July 17, 1942, No. 9962. [Class 37] In an instrument of the moving coil type in' which the moving coil swings in an arcuate gap between the pole shoes of a central permanent magnet and an outer ring of magnetic material the field intensity in the gap is adjustable by means of a member of magnetic material which can be positioned so as to provide a more or less easy short circuit magnetic path between the pole shoes. The framework of the mechanism consists of a ring-shaped pole-piece 19 to which two die cast supports 14 are rigidly attached by rivets 24. The central cylindrical permanent magnet 17 has a flat on one side and is fitted within a cradle comprising a pedestal 21 and a pair of diametrically opposite pole shoes 18, the pedestal being adjacent to the flat and ensuring that the magnet is assembled in a definite angular position. When assembled the magnet is magnetized across its diameter, the magnetic axis being parallel to the flat and corresponding to the direction of the magnetic field in which the material was heat treated. The magnet and pole shoe assembly is held in the ring 19 by the pedestal 21 which is located in one of the recesses in the ring and secured by a screw 23. The pivot bearings, control springs, and adjusters for the moving coil 20 are mounted on two bridge pieces 38 which are attached to the frame by screws 39 and insulated by bushes and washers. The open ends of the pole shoes 18 are extended towards one another at a reduced width and machined off flat on their extended portions. A screwed plunger 40 forms a variable magnetic shunt for adjusting the deflection of the instrument. In modifications the flux is non-uniformly distributed around the gap, as by making the poles or upstanding portions of the outer ring non-circular or eccentric to the axis of the magnet.

Title: Ignition control systems
IPC: F02P3/04
Filed: 1972-12-12
Abstract: 1409748 Ignition systems FAIRCHILD CAMERA & INSTRUMENT CORP 12 Dec 1972 [6 April 1972] 57293/72 Heading FIB While the engine is operating at a low speed an initial bias reference circuit 13 controls the turn-on and turn off of the Darlington output circuit 19. The circuit 19 is turned on when the waveform from the pick-up coil 10 rises above the threshold voltage produced by the circuit 13 and is turned off when this waveform falls beneath this voltage. Turning on of the circuit 19 causes a current to flow through the primary coil 31 of the ignition coil 30. Turning off the Darlington output circuit 19 induces a voltage pulse in the secondary winding 32 of coil 30 which fires the appropriate sparking plug. When the engine speed reaches a given value a signal from the dwell feedback control 12a turns on the Darlington output circuit 19 when this signal rises above a reference level. This reference level increases as the engine speed increases turning on the Darlington output circuit 19 at an earlier time. A current limiter 16 in a LIC (linear integrated circuit) chip 20 changes the reference voltage produced by a tachometer 12b to a new value such that the current through primary 31 remains at its maximum value for at most a selected short period of time. A transient protection device operates to turn off the Darlington output circuit 19 if the transient voltage rises above 28 volts. This is done by turning on the output driver circuit 15. To limit the current in the case of an over-voltage condition in the LIC chip 20 current limiting resistors are placed in every current path. The current in the primary winding of the ignition coil remains on while the amplitude of the output signal from the coil 10 increases to a maximum positive value and then drops very sharply towards a peak negative value. The level of the signal from the coil 10 at which the current through the circuit 19 cuts off is beneath a reference voltage by an amount controlled by certain circuit parameters. The system can be produced using only two semi-  conductor chips. One chip is the basic LIC chip 20. The other chip contains the Darlington output circuit. Details of the circuitry of these chips are given in the Specification.
