[Also in Divisions B2 and F2] A valve controlling the supply of liquid to a series of spray tubes on an agricultural sprayer includes a plunger 14 slidable axially in cylinder 10 to control communication between inlet 32 and outlet 24. A spring 18 biases the plunger to its closed position and a bifurcated cam lever 30, 33 serves to lift the plunger against the spring when such lever is rotated in a vertical plane, the plunger stem 15 having a pin 31 connected to yokes 30 and passing through vertical slots 35 in posts 36. When the valve is opened, an extension of pin 31 actuates a switch plunger 28 to start a motor which oscillates the nozzles fitted to the spray tubes, the latter being secured to tubes 25. The plunger has a rubber seating disc 16; such a disc could alternatively or additionally be secured to wall 11 of cylinder 10. Atmospheric pressure retains the liquid in the spray tubes when the valve is closed and prevents dripping. In Fig. 3, not shown, such a valve is supplied from a tank via a stop valve, filter, pump and pressure regulator. A re-cycling line from pump discharge to tank allows agitation of the contents of the latter.

Abstract: 1,160,240. Determining free energy. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. Nov. 22, 1966 [Nov. 23, 1965], No. 52145/66. Heading G1S. An instrument for measuring the free energy of a solvent at a given locality in an environment, comprises an enclosure 17 filled with a standard solution of the solvent, the enclosure being defined by a boundary wall at least a portion of which is constituted by a membrane 21 which is permeable to the solvent and impermeable to the solute molecules of the standard solution, and means 18 for quantitatively sensing pressure changes in the standard solution brought about by the presence of the solvent in the environment. A porous support 23 is provided for the semipermeable membrane extending over the whole area of the membrane. The enclosure 17 is connected via an axial bore 16 to a conventional strain gauge transducer 18. The standard solution is an aqueous solution of polyethylene glycol which is added or removed through a ball-valve 27 in the side of the container. In operation the device is placed with the porous support 23 in contact with the environment such as soil under test, the enclosure being full of a standard solution of the solvent. Any difference in moisture content will result in the flow of the solvent from the environment through the membrane and into the enclosure until equilibrium is reached. The increase in solvent in the enclosure will result in a rise of pressure indicated on the pressure transducer 18.

Title: Cryosurgical appliance
IPC: A61B18/02
Filed: 1968-11-08
Abstract: 1,243,248. Cryosurgical appliances. LINDE A.G. 8 Nov., 1968 [10 Nov., 1967], No.53162/ 68. Heading A5R. A cryosurgical appliance for freezing and removing undesirable body tissue comprises a handle 12, Fig. 2, to which is fixed an intermediate member 13 carrying a liquid nitrogen container 14 of about 300 cn<SP>3</SP> capacity and a tubular probe 16 having a thermally insulated shank and a thermally conductive nose 30, Fig. 3, in which coolant passing from the container 14 through flow controlling means is evaporated to cool the nose by a controlled heater adjacent the nose, the gas so formed being fed back through the probe and handle into a discharge hose connected to a union 20 on the handle. The discharge hose is connected through an electromagnetic valve to a suction pump. The appliance also has a viewing and illuminating system comprising a fibre optical light guide 18, a member 18a which connects the guide 18 optically to a further light guide and thence to a cold light source (E), and a removable optical viewing system 17. The probe 16 consists of three coaxial thin-walled tubes made of, for example, stainless steel. In the tube 28 the liquid coolant flows to an evaporator 29, which may consist of a thermally conductive wire coil, which establishes good thermal contact between the evaporating coolant and the probe nose 30 surrounding the evaporator. The nose 30 may be unscrewed from the probe and replaced by other noses having a shape appropriate to a particular operation. The gas produced in the nose escapes through the space 31a between the innermost tube 28 and the central tube 31. The space 32a between the central tube 31 and the outermost tube 32 is evacuated. A heater coil 33 can be used to heat up the nose to release it from frozen tissue and is operable by a switch 36. The probe nose can be given a shape such that it has a piercing portion which is visible through the viewing system 17, Fig. 2, the invisible parts of the nose being rounded off. The probe carries a finger rest 22 having a cone 22a onto which a device (21), Fig. 2 (not shown) may be connected for treatment of tissues frozen by the probe. The finger rest 22 and treatment device (21) are axially movable relative to the probe 16, selected relative positions being fixed by a control 24. A switch 35, when closed, opens the electromagnetic valve between the gas discharge hose and the suction pump so that gas may escape from the system and coolant may flow to the probe from the container 14 which is pressurised. The handle also carries a heating element switched on by switch 35, to heat the outflowing gas to about room temperature so that the gas discharge hose remains flexible. The container 14 has an evacuatable jacket and a pressure tight cover 15 carrying a regulating and safety valve 27 and a thermoelectric device 26 to indicate when the container needs refilling. The appliance may be connected to an automatic replenishment device (50), Fig 5 (not shown).

The tape 14 is twisted through 180 degrees and is guided through, in the embodiment shown, two sheaves 62, by a plate 60 which has a central vertical slot. The lower plate 52 has a transverse plate 66 provided with web extensions (68), Fig. 7 (not shown), at each end, which each engage over a latch 70 when the assembly 10 is in its raised position. The locking means 76 comprises as shown on each side of the plate 50 a shear pin 80 held in a retainer 78 on a catch plate 72. A resilient pad 90 for each locking means 76, engages a web extension (68) of the plate 66 to cushion the shock when the assembly 10 reaches its raised position. In a second embodiment, Figs. 8, 9 (not shown), a single sheave (62A) is mounted at an angle to the plate 52 to guide the tape 14 which passes from a pit mounted shock absorber (18A) under a roller (100A) to an elevated net (16A). The net (16A) rests in a cross runway trough when not in use.
