In an arrangement for the programmed control of the cultivation of a plant in a culture space or chamber an experimental plant is first grown under natural conditions and the time variations of the factors affecting growth entered in a chart. The recorded factors include the temperatures of the air and culture medium, atmospheric humidity, wind velocity, insulation, pH value, rainfall and growth. A record experimental of controlled growth is then conducted with the growth-impeding factors modified and a record chart obtained. Further growth periods are established in a similar way to derive an optimum vegetation or growth chart which is then programmed on a punched card. The punched card is employed to electrically control appliances for bringing about particular climatic conditions in a culture chamber in order to conduct plant culture on an industrial scale. It is stated that special greenhouse installations may be employed in which the culture chambers are arranged on the paternoster or endless chain principle in high towers united to form large building units. Separate culture chambers, each programme controlled by punched cards, can be employed for sections of the growth cycle, arrangements being provided between each two chambers for transferring culture vessels or containers from one to the other chamber.

Abstract: 1318436 Grinding LITTON INDUSTRIES Inc 19 Aug 1970 [20 Aug 1969] 39851/70 Headings B3B, B3D and B3T A mechanism for locking a machine part in a working position, such as the tailstock 14 of a cam grinding machine, comprises means for preventing movement of an hydraulic piston and cylinder 18 from a selected position by momentary excessive loads, and means to discharge trapped air from the motor direct to exhaust without having to pass through a reversing or other control valve. As described, a headstock (13, Fig. 1, not shown) and tailstock 14 support a workpiece W for rotation and axial movement on a carriage (12) movable along a bed (11) for grinding by a wheel 15 movable transversely of the workpiece. The hydraulic cylinder 18 has a piston 19 to prevent movement of the tailstock centre 17 as a result of grinding forces acting on the workpiece, the piston 19 having an adaptor 22 acting on the tailstock spindle 23. A first conduit 27 connects through a first check valve 28 the head end of the cylinder to a control valve 24 joined by a conduit 26 to a reducing valve 31 and a conduit 33 to a drain 34. The head end of the cylinder is also connected by a second conduit 51 to a port 42 of a second check valve 29 mounted close to and above the head end of the cylinder. The rod end of the cylinder is connected by a third conduit 53 to the control valve 24 and by a fourth conduit 54 to a pilot port 50 of the check valve 29 which has a further port 43 connected by a conduit 52 to the drain 30. The check valve 29 consists of a housing 35 having three bores 36, 37, 38 interconnected by a passage 40 having a part 41 formed as a cylinder. The spring-loaded ball 44 normally closes the connection between passages 37, 38 which are respectively connected by ports 43, 42 to the drain conduit 52 and second conduit 51. The passage 36 is connected by port 50 to the fourth conduit 54 and fluid pressure in passage 36 can act on a reduced portion 48 of a piston 46 to move it to the right so that a projection 47 lifts the ball 44 from its seating. In operation, the tailstock centre 17 is locked to prevent longitudinal movement of the workpiece by actuation of valve 24 directing fluid through the first conduit 27 and first check valve 28 to the head end of cylinder 18, the check valves 28, 29 then preventing movement of the piston 19 and centre 17 to the right. After the grinding operation, the valve 24 is again activated to supply fluid pressure from conduit 26 to the third conduit 53 and rod end of the cylinder 18 and through the fourth conduit 54 to port 50 and passage 36 of check valve 29 so that the piston 46 moves to lift ball 44 from its seating whereby fluid from the head end of cylinder 18 can pass through the second conduit 51, port 42, and passages 38, 37 to the drain conduit 52 and drain 30. This results in free flow of fluid and any entrained air therein being exhausted from the head end of the cylinder and fresh fluid free of air being used for the next operation.
