Title: Improvements relating to apparatus for the conditioning of corn
IPC: A01C1/08
Filed: 1936-10-17
Abstract: 489,537. Delivering materials from hoppers. STUMPFIG, F., and HASSLER, O. Oct. 1,7, 1936, No. 25458. [Class 78 (i)] [Also in Group I] Apparatus for conditioning grain comprises means whereby the rate of admission of the conditioning-chamber is controlled automatically always to be proportional to the rate of admission thereto of the grain. As shown in Fig. 1, the grain flows over a shoot a pivoted on a shaft b which is rapidly reciprocated in the direction of the arrow. Balance weights c, d are provided, and the shoot assumes a greater or lesser inclination accordingly as the flow of grain is greater or lesser. Ina modification, the shoot a is replaced by a bell - shaped member which is rotated on its own axis by a cord-driven pulley. The pivot shaft is not reciprocated in this case. The bell may have worm or pocket means for moving the grain from it quickly. Alternatively, the element which is displaced by the grain flow may be a spring scale. The displaced member may be connected to a pointer for indicating the thickness of the stream of grain, but is, in all cases, operatively connected to means for controlling the flow of the conditioning-medium. As shown in Fig. 4, a wet medium is supplied from a pipe a<III> to a constant level reservoir b<III> connected to an outlet member i bv a flexible connection c<III>. The shaft b, or other member displaced by the grain flow, raises the member i as the grain flow decreases and vice versa. The flow from the member i is over an interchangeable weir g<I>. The reservoir b may be supplied by a bottom connection from another constant level reservoir. In a modification, the wet medium is allowed to fall in a wide ribbon-like stream from the bottom of a vessel supplied by a pump. A deflecting-plate, under the control of the grain-displaced member, is arranged to deflect more or less of the stream into the conditioning- chamber. In Fig. 6, a dry medium is fed from a hopper b<IV> by a reciprocating member c<IV> having a pocket d<III> which is filled to an extent depending upon the stroke of the member c<IV>. The wedge f<III> is under the control of the member displaced by the grain flow and is interposed, to a greater or lesser extent according to the flow, between a constant stroke power-driven rod g<II> and the spring-returned rod e<III> carrying the member c<IV>. Since the movement of the rod e<III> is limited in one direction by the collar i<I>, the wedge f<III> determines the stroke of the member c<IV>. In a modification. the extent of opening of a sliding gate in the side wall of a hopper for conditioning-medium, is determined by a double wedge, i.e. two wedges having their thin ends together, under the control of the grain flow member. The double wedge, according to its position, determines the extent of movement imposed upon the gate by a power-driven reciprocating rod. Reference has been directed by the Comptroller to Specifications 377,343 and 386,395, [both in Group I].

Filed: 1932-09-15
Abstract: 407,354. Arc-rupturing in switches. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Slepian, J.; 1115, Lancaster Street, Pittsburg, U.S.A.) Sept. 15, 1932, No. 25670. Convention date, Oct. 13, 1931. [Class 38 (v).] In order to extinguish an arc, solid material is provided which, when acted upon by the arc, generates a non- inflammable, preferably condensable gas which passes through the arc in the form of a blast. A tubular casing 5 of fibre (Fig. 4) contains a series of discs 15 of the solid material, through an aperture 17 in the centre of which discs passes the movable contact 43 into engagement with fixed contacts 41 under spring action 45. When the contact 43 is lowered to open circuit, the arc formed acts on the material comprising the discs 15, thereby generating gas which passes up through the space between the contacts 41 into a number of small condenser tubes 39, the gas deionizing the arc in its passage therethrough. Suitable materials are ammonium alum, gypsum, and boric acid, the latter being preferred because of its good insulating properties even at high temperature, and of its non-hygroscopic nature. Fusible cut-outs. Fig. 1 shows a fusible strip 19 within the aperture 17 in the discs, the strip being connected to a collar 27 under spring action 29. Connection with the terminal 9 is made by means of a disc 33 and conductor 35 which slides on the collar 27.

Title: Vehicle speed arrester
IPC: B60K31/08
Filed: 1924-10-29
Abstract: 243,142. Gore, C. Oct. 29, 1924. Automatic speed or power control; fluid speed indicators.-A pump driven at a speed proportional to the speed of the vehicle circulates fluid in a chamber and raises a plunger which first gives a visible warning signal, then breaks the ignition circuit if a predatermined speed is reached, and finally applies the brakes if that speed is exceeded. A shaft 22 rotated from some driven part of the vehicle drives a speedometer 24 and a rotary pump 18 which circulates liquid from a tank 13 through a passage 14 and ports 17 controlled by a spring-pressed plunger 19. The plunger carries a contact member 49 which, as the plunger is raised by increasing pressure due to a rise in speed, makes contact with adjustable members 55 and completes a circuit through a signal lamp e. If the speed still rises a stem 33 carried by the plunger lifts a switch arm 31 and breaks the ignition circuit at contacts 32. A still further rise in speed causes the contact member 49 to make contact with an adjustable member 56 and so energize a solenoid g which trips a lever 59 and allows a spring 61 to apply the brake 62. The trip lever is re-set by means of a hand lever 65. When the switch arm 31 is raised to open the ignition circuit a counter 39 is operated to record the event and the arm is temporarily held up by a catch 36 which is tripped by an incline 38 on the stem 33 when the speed has fallen again. The switch lever is carried by a block 27 which may be adjusted on a screw 25 so as to vary the speed at which the ignition circuit is broken. The signal contact 55 is also carried by the block 27 but is independently adjustable thereon by means of a screw 29. In a modification the ignition circuit is broken by a solenoid which is energized when a contact in its circuit is reached by the contact member 49 on the plunger. In this case the ignition circuit is re-established, after the speed has fallen, by means of a press-button. The whole apparatus is enclosed in a case 10 which may be locked to prevent tampering.
