Abstract: 408,370. Treatment of growing plants; implements for working land. STRANZ F. SCHRODER-, 10, Flemmingstrasse, Steglitz, Berlin. Nov. 14, 1932, No. 32178. Convention date, Oct. 17. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 15, 1933.] [Classes 6 (i) and 6 (ii).] A machine for pressing growing plants deeper into the soil consists of a transportable frame adapted to be drawn over the plants and on which elements are mounted which grip the plants from above and press them vertically downwards. Each of these elements or rams terminates in diverging prongs 14 which on descending first move soil inwards before pressing the plant downwards, and on ascending move the soil slightly as they rise. The rams may be made of rubber &c. Planted strips of land may alternate with unplanted strips on which the machine wheels may run. The rams 13, Fig. 6, are arranged in a cross-head 15 with springs 16 tending to lift them. They are pressed downwards periodically by projections 25 on a drum 19 driven from the rear wheels 22 by a chain 24. In a modified machine the rams 13 are reciprocated vertically by one or more cranks and are movable longitudinally of the machine by cams and springs so that they are not moved in the direction of travel of the machine while in the ground. In another modification the rams are mounted in rows on a frame linked to one of a pair of cranked axles which are coupled together and rotate with the travelling wheels, the lower end of the link being connected by a long slotted link with a pin on the rod coupling the axles together. In the arrangement shown in Fig. 12 the rams 13 are pivoted on pins 42 mounted in a circle between discs 43 keyed on the axle of the ground wheels mounted in a frame 47, the pivotal movements of the rams being limited by abutments 46. The rams may be mounted on a soilloosening machine, or soil-loosening implements may be mounted on the machines described. The Specification as open to inspection under Sect. 91, comprises also the following method of cultivating cereal plants. The seeds are strewn thinly directly on the surface of the ground and then immediately covered with a layer of loose soil, turf, humus or the like, which is wholly or partly removed after the seeds have germinated. When adventitious roots develop they may be covered with crumbled soil, and later on the plants are earthed up. The ground may be levelled after the plants have been pressed deeper into the soil. Some of the soil around plants in drills may be removed, before treatment, by forming furrows besides the rows and then harrowing or levelling. Seeds may be strewn at the bottoms of furrows and soil for forming the loose layer and for earthing up may be taken from between the furrows. This subject-matter does not appear in the Specification as accepted.

Filed: 1932-11-17
Abstract: 409,792. Reversible seats. PETERS & CO., Ltd., G. D., and WHITE, H. B., Windsor Works, Slough, Buckinghamshire. Nov. 17, 1932, No. 32566. [Class 52 (ii).] A reversible seat for vehicles has a supporting framework 28, 29, Fig. 2, fixed in such a position that one end of the seat 10 abuts against a wall of the vehicle, the seat proper being rotatably mounted on a pivot pin carried by an upper frame 12, 14, which is slidably mounted on the supporting framework, the seat being held against rotation when in position for use, and the upper frame being held against sliding movement during rotation of the seat. The seat 10, Fig. 3, is substantially rectangular and is mounted on an under frame comprising angle irons 12, 13, Figs. 3 and 4. Girders 15 are secured to the angle irons and to a plate 18, the latter being mounted on a revoluble restraining plate 19 by rivets and spacing washers 21. Below the plate 19 is mounted a pivot pin 24 which passes through an elongated slot 25 in a fixed table 26 which is mounted on a fixed framework 28. The seat is moved away from the wall 30 of the vehicle in order to permit it to be rotated, by means of a pedal 42 which actuates a slide 37 through which passes the lower end of the pin 24. Springs 38 return the slide and consequently the seat when the pedal is released. To retain the seat in either position of use, bolts 45 are mounted on the revolving under frame, and an arcuate guide rib 46 with a central aperture in which one of the bolts normally engages is mounted on the fixed frame 38. The restraining plate 19 has an arcuate edge 48 and two opposite radial slots 49, in one of which is normally located a pin 51 on the fixed table 26. This prevents rotation of the seat until the revolving framework has been moved laterally by depressing the pedal 42. The plate 19 is also formed with stops 52 which prevent rotation of the seat through an angle greater than 180‹. To relieve the pin 24 of the weight of the passengers, stops 53 are mounted on the revolving frame and bear normally on the fixed frame 28, engaging also in notches in bars 54.

Abstract: 804,143. Gas turbine plant. ROLLSROYCE, Ltd. Dec. 19, 1956 [Nov. 16, 1955], No. 32877/55. Class 110 (3). [Also in Group XXIX] In a gas turbine fuel-control system having a variable capacity fuel pump and servo means for varying the capacity, means are provided to lock the servo means and so prevent variation of the pump capacity. An engine-driven, variable-capacity, swash-plate type plunger pump 13 has its capacity varied through the swash-plate by the piston 42 having one side 45 exposed to pump delivery pressure and the other spring-loaded side 41 exposed to pressure derived from the pump delivery through the orifice 44 and under the control of two hinged leak-off valves, valve 30 being actuated in response to atmospheric pressure on the capsule 37 and pump delivery pressure on the piston 33, the other valve 55 being actuated by diaphragm 52 responsive to a pressure proportional to the engine speed. To prevent surge or stall in aircraft gas turbines when the aircraft guns are fired, fuel is bled from the pump delivery to the burners 23 through a valve 62 controlled by a spring-loaded piston 61 under the control of a solenoid actuated valve 68. To prevent the servo means adjusting the pump in response to the fall in engine speed and pump delivery pressure, a normally open solenoid valve 81 is closed prior to the opening of the bleed 62 whereby the piston 42 is locked in its operated position with the cylinder space 41 isolated from the control pressure in pipes 40, 58. Either engine speed or pump delivery pressure, or both together may control the servo means.
