Title: Inductive storage ignition systems for internal combustion engines
IPC: F02P3/045
Filed: 1973-01-25
Abstract: 1386192 Ignition systems BROWN BOVERI & CIE AG 25 Jan 1973 [28 Jan 1972] 3893/73 Heading F1B An inductive ignition system for an internal combustion engine includes a high voltage circuit including a secondary winding 5 of an ignition coil, a low voltage circuit including a primary winding inductively coupled to the secondary winding, the primary winding comprising a first low resistance section 3 and a second high resistance section 4 connected in series with the first section, means for sequentially energizing the first section and the second section of the primary winding from a D.C. power source 10 and a diode 8 connected in series with the second section to prevent current flow therein as a result of voltage induced in the second section by current flow from the power source in the first section. When the contact breaker switch 1 is closed an initial current i 1  flows in the windings, 4, 3 and induces a voltage in the winding 11. This causes a current i 2  to flow to cause the transistor 12 to conduct. This provides a charging current i 3  to the winding section 3. The charging current rises to a peak value of for example 12 amps. When this value is reached the common core of the windings 5, 6 and 11 is saturated as a result the current i 2  ceases and the transistor 12 returns to its blocked state. When the current through the winding section 3 ceases a current I H  is establised through the winding sections 4, 3. This current acts as a holding current. Opening of the contact breaker switch 1 results in a flow of current in the high voltage circuit 5 and a spark at one of the sparking plugs 9. A simplified embodiment and an embodiment including two control transistors are described. The/or each transistor can be replaced by a thyristor.

Abstract: 1450462 Venetian blind having tilt-limiting attachment LEVOLOR LORENTZEN Inc 29 Jan 1974 [8 March 1973] 04123/74 Heading E1J A Venetian blind has a ladder and slat assembly and a head comprising an elongated channel 16 containing a lifting mechanism and a tilt bar 24 which may be rotated by a tilter 30. A limit member 44 is fitted on the tilt-bar adjacent to the tilter. A stop member 50 fits so that the main part 50a is between the tilter and the head channel wall 20b, positioned by 50b and c and is retained by the latch 50f snapping beneath the inturned flange of the channel; it has a hook portion 50h which retains the limit member in position. The rotation of the tilt-bar (and hence the tilt of the slats) in either direction is limited by the cut-off edges 44b or c of the limit member striking the offset 50g of the stop member. The degree of tilt may be altered by the use of limit members with different cut-off segments.

The plate to be inspected is pivoted forwardly and upwardly until the slot 20 is disengaged from the supporting rod 12, Fig. 3, and is then swung outwardly for inspection or cleaning as shown in Fig. 4 with the rod 14 acting as pivot. By further pivoting of the plates the hook 24 is removed from engagement with the rod 14, and the plate may be removed.

Title: Improvements in the control of power-operated systems for tractor hitch linkages
Inventor: BUNTING ERNEST VIRDEN
IPC: A01B63/112
Filed: 1951-02-21
Abstract: 743,117. Agricultural implements. FERGUSON, Inc., H. Feb. 21, 1951, No. 4205/51. Class 6 (1). [Also in Group XXIX] In a tractor hydraulic-lift system a release valve 190 is provided for exhausting the hydraulic ram 36 when the draught-control linkage 26, 101 moves beyond its normal travel, the valve being adapted to open upon actuation by the linkage and to remain open subsequently, independently of the linkage, until the oil supply to the ram is terminated by the tractor operator. The system is similar to that described in Specifications 470,069 and 470,087 and comprises a ram acting on an arm 41 connected to a rock-shaft 42 from which the liftarms 43 extend rearwardly. The upper hitchlink is connected to the rocker 26, movement of which, in response to variations in draught load, actuates a control valve 50 connected between the oil-pump 46 and ram 36, as is described in Specification 743,118, [Group XXIX]. The rocker drives a plunger 101 connected by a link 109 to a pivoted arm 112 carrying a roller 114. Excessive movement of the rocker 26 causes the roller to strike a push-rod 210 and open the valve 190 through a further rocker (Fig. 4, not shown). The valve (see Group XXIX) comprises a spring-loaded double-piston sliding in a composite cylinder, the piston areas being so chosen that the valve is normally closed but when operated by the linkage 101, 109, 112, 210, it opens automatically and thereafter remains open until the fluid supply is interrupted by manual operation of the hand control 60. Specification 550,142 also is referred to.
