Headings F2C, F2E and F2L. A freewheel clutch comprises spring-pressed rollers 13 between recesses 15 in a driven member 16 and the inner surface of a sprocket 10 which is rotatably mounted on member 16 which in turn is rotatable on a fixed shaft 19. Lugs 23 on a control ring 22, Fig. 3 (not shown), project into recesses 15 ahead of rollers 13, the ring having a lug 25 co-operating with a member 26 of a clutch release mechanism. Spring-pressed rollers 29 are housed between member 16 and a fixed recessed ring 28. A pin on the member 16 engages in a fork on a lever fixed to a further shaft to oscillate this further shaft on rotation of member 16. In operation with sprocket 10 rotating, the member 26 releases the control ring and rollers 13 cause sprocket 10, member 16 and control ring to rotate together until the lug 25 again engages stop member 26 to arrest the control ring whose lugs 23 move the rollers out of wedging engagement. The rollers 29 and ring 28 prevent any return movement of the member 16 to accurately stop and lock it after one revolution.

Abstract: 1304701 Boring earth STICHTING WATERBOUWKUNDIG LABORATORIUM 6 Feb 1970 [7 Feb 1969] 5873/70 Heading E1F In a process of taking an undisturbed soil sample using a core tube having an annular chamber 4 for a stretchable hose 24 arranged to surround and support the sample 25 in the tube, a detachable tube 18 is provided to support the hose 24 and sample 25. A lubricating liquid - for example an oil - is provided between the tube 18 and the hose to allow the hose and sample to move upwardly in the tube without disturbance. A supporting liquid flows through holes 23 into the bottom of the chamber and creates an appropriate pressure to urge the hose against the sample before the hose reaches tube 18. The inner wall of the chamber is formed by a tube 17 surrounding rods 14 which connect a lower ring 12 to an upper ring secured by a ball joint to the core tube. As the core tube is pressed into the soil further sections are screwed to the core tube and further sections are connected to tube 18 by adhesive tape. A cable 32 keeps the top of the hose at the same height, as the core tube and tube 18 move into the soil. A torsion sleeve (35 Fig. 1) is moved by rotation of the upper sections of the tube 18 to grip the sample when the core tube is withdrawn. The core sample is transported in the sections of tube 18 after the adhesive tape and sample has been cut by, for example, a wire connected to a direct current source.

Title: Improvements in battery charging equipment
IPC: H02J7/12
Filed: 1939-02-22
Abstract: 525,248. Charging batteries. HINDS, R. S., MANDL, A., and, METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 22, 1939, No. 5903. [Class 38 (iv)] A battery 6 is charged from an A.C. source 1, 2, through a rectifier 4, and a choke coil 5 in the supply circuit to the rectifier is controlled in accordance with the changes in battery voltage as charging proceeds so that the charging current remains uniform over the charging period. The coil 5 has a saturating winding 5<SP>1</SP> connected across the battery opposing a second saturating coil 5<SP>11</SP> energized from an auxiliary rectifier 4<SP>1</SP> in accordance with the difference between the supply voltage and the voltage input to the rectifier. In this way compensation for supply voltage variations is also obtained. When the battery voltage attains a predetermined value a relay 11 operates to energize an electromagnetic switch 13 which changes a tap connection on the supply transformer 3 to reduce the charge to a gassing rate. A resistance 20 is inserted in the circuit of the coil 5' when the charge is made. A timing motor 10 energized by operation of the relay 11 terminates the charging after a predetermined time. A selector switch 17 may be positioned so that operation of the switch 13 changes from normal to conditional charge. In this case the motor 10 is rendered ineffective by a switch 26 coupled to the selector switch. A resistance 19 controlled by the switch 13 prevents " hunting " of the relay 11. In Fig. 2, not shown, the second coil 5" on the choke coil 5<SP>1</SP> is energized from an auxiliary rectifier connected across taps on the coil 5. In this arrangement the leakage of the tapped section increases with saturation.
