Title: Improvements in and relating to electric discharge apparatus
IPC: H02M1/04
Filed: 1935-06-28
Abstract: 459,055. Converting. LEHMANN, W., 45, Trabenerstrasse, Grunewald, Berlin. June 28, 1935, Nos. 18625, 18626, and 18627. Convention dates, June 28, 1934, Nov. 16, 1934, and April 13, 1935. [Class 38 (ii)] [See also Group XL] In a gas or vapour filled rectifier the discharge is controlled by high-frequency oscillations generated by interposing an apertured screen 10 between auxiliary anode 9 and a cathode 11 in an auxiliary vessel 8, and subjecting this discharge path to a suitable potential obtained from a source 14 ; an inductance 13 is included in the circuit. The high-frequency oscillations thus obtained are applied in turn across the gap between the main anodes 3 and the grids 6 to ionize the filling and neutralize the blocking effect of the grids ; a rotary switch 15 driven by a synchronous motor 20 connects the source 8 to the rectifier through resistances 16 either directly or through auxiliary discharge devices 27 for raising the voltages. The auxiliary vessel may be built into the main rectifier body 1, in which case the main cathode 2 may be used with the auxiliary anode instead of the auxiliary cathode 11. Instead of supplying the oscillations to the gaps between the main anodes and grids, they may act in a coil surrounding the rectifier. The time of breakdown of the main gaps can be varied by adjustment of the switch 15. In a further arrangement, the anodes 3, Fig. 4, and grids 6 are included in oscillatory circuits, comprising inductances 107, 107<1>, blocking condensers 124 preventing direct connection of the main transformer 21 to the rectifier body 1. The generated oscillations from the vessel 8 are supplied to coils 126, 126<1> inductively connected with the coils 107, 1071 ; the vessel 8 may be built into the main rectifier body as shown in Fig. 3. The anode sleeve 5, Fig. 7, may be supported from an insulator 41 for the anode, the lead-in for the local oscillatory circuit being through a second insulator 7. In rectifiers with glass envelopes, the anode sleeves 130, Fig. 8, inside the envelope and outer coatings 131 form part of the capacity in the oscillatory circuits including the grids 6 and anodes 3 ; additional condensers 132 may be included in the circuits or if small capacities are desired, the anode sleeves may be omitted. In another modification, " fly-wheel " circuits each consisting of a condenser 127, Fig. 9, and inductance 128 are included in the connection between the transformer 21 and the anodes 3, these circuits being coupled to coils 126 receiving high - frequency oscillations. Specification 414,457 is referred to.

Abstract: 1469537 A crop gathering reel for a harvester INTERNATIONAL HARVESTER CO 29 April 1974 [27 April 1973] 18630/74 Heading A1F A crop gathering reel for a crop-harvesting platform 10 comprises a rotatable shaft 34, which is journalled in brackets 38, 40 adjustably mounted on respective arms 42, 44 of the platform 10, a plurality of discs 36 mounted on the shaft 34 and spaced from one another to define crop-receiving passages, fingers 78 pivotally mounted as pairs of units 68 on the discs 36, and means such as a roller 94 riding on a cam 96 for swinging the fingers 78 from an inoperative position, which is defined by the fingers 78 of each disc 36 having a plane which lies in the plane of the disc 36, to an operative position wherein the fingers 78 extend substantially perpendicularly to the plane to engage standing crops. Finger portions 70 and 72 of each unit 68 are welded to arms 80 and 82 which are made to interengage along a stop surface 90 by a spring 86. To obtain the operative postion the roller 94 of each nut 68 rides on a cam-lobe 106 of the cam 96 of the unit 68 and causes the portion 70 to pivot in a direction perpendicular to the plane of the disc 36 which concommitantly moves the arm 82 towards the arm 80 thereby pivoting the finger portion 72 in the opposite direction. When the roller 94 leaves the camlobe 106 to ride on a vibration-reducing cushioning, surface (108) Fig. 7 (not shown) the. fingers 78 are returned to their original inoperative position by the spring 86. The cams 96 can be connected to braces 116 at any one of circumferentially spaced openings 124 provided on flanges 120 of the cams 96 to pre-select the point at which the fingers 78 are swung into and out of the operative position, which situation is dictated by different types of crops.  Annular plates 58 are welded to the outer peripheries of tubes (54) Fig. 5 (not shown) of the discs 36, which tubes (54) are received about the shaft 34 The outer peripheries of the plates 58 are secured by shields 62 and (126) Fig. 5 (not shown) for covering the operative elements of the discs 36. The reel is rotated by a hydraulic rotary motor 110, which is mounted on arm 44, and a chain and sprocket drum 112. The platform 10 includes a crop-consolidating auger 32 and a reciprocable cutter 30 disposed along the forward edge of the platform bottom wall 18 for cutting standing crops as the platform 10 is moved forward.

An electrically heated container comprises a pot E, Fig. 1, an insulated heating resistor R, and a joint bimetallic blade responsive to the temperature of the pot and operating a first switch X when the temperature exceeds a prodetermined value. Operation of the switch X completes a circuit to a heater r, located in a base 43, Fig. 7, on which the pot rests, which heats a second bimetallic strip to operate a second switch having contacts i which break the circuit to the heater R and r. The first bimetal strip is located between the inner wall and the outer wall of the pot E and the pot is formed with a double bottom in which is located the heater R. The pot is provided with plugs fitting into sockets to the base 43 for connecting together the leads 1, 2, 3, the supply flex 50 being led into the base at C, D. A pilot ]amp in parallel with a resistance A is included in circuit for indicating when the pot is energized. A dial is provided on the handle for operating a rod in the handle to adjust the temperature at which the heater r becomes energized. A correct relation between the pot and the base is maintained by a protrusion a on the pot and loop d on the base.

[Class 139.] A watch case comprises portions 3, 4 adapted to slide on the frame 2 carrying the time movement, by means of ridges 7, 8 engaging grooves 5, 6, springs 9, or alternatively a tensioned blade spring, preferably separated from the ridge 7, by a small tongue (not shown) inserted in the groove 5. Abutments 24 on members 22, 23 slidable in grooves 26, 27 on the frame 2, are forced by a spring 20 mounted on a rod 21, Fig. 3, against the inside of portions 3, 4 to absorb any play, and co-operate with shoulders 25 thereon to prevent complete removal thereof from frame 2. Nose parts 28 of members 22, 23 engage snail cams 29, the heads 30 of which are slotted that they may be easily turned to displace the members against the action of spring 20 when the portion 3 or 4 is to be completely removed. An easel leg 10 is fixed by a screw 11 to an axle 12 rotatably mounted in the back of frame 2, and is urged to assume the position shown in Fig. 3 by a spring 14 connected to a lever 13 fixed to axle 12. When the case is closed, reinforced parts 17 on the inner edges of the halves 3, 4 engage with the inclined slopes of the easel reinforcements 16, thereby rotating the easel leg against the action of spring 14 to a position parallel to the frame 2 when the halves 3, 4 may be pressed together.
