Abstract: 1,047,735. Concrete pipes. A. P. PEDRICK. Jan. 24, 1966, No. 15343/64. Heading F2P. [Also in Divisions B2, B5 and F1] A concrete pipe for a long pipeline is cast in a continuous length by pouring concrete into a funnel 60, Fig. 14(a) (not shown), and pumping it by a pump 62 into an annular mould 64, 65, reinforcing cables 67 being fed in from drums 66. The setting of the concrete may be accelerated by a blast of hot air from a turbojet engine 70. The pipe is drawn continuously from the mould by a cable 69. An outer sheath 15, Figs. 6 and 7 (not shown), of flexible sheet material such as rubber, is formed around the concrete pipe 18 by drawing a strip 72, Figs. 14 (c), (d) and (e) (not shown), of the material from a roll 71 and wrapping it around the pipe, a narrower strip 74 drawn from a roll 73 being fastened to the edges of the strip 72 by means of a riveting or fastening machine 75. The pipeline runs below the sea for most of its length. The interior of the pipe 18 is evacuated to a low pressure by centrifugal vacuum pumps 20 driven by electric motors 21 and arranged at intervals along the pipeline, the electrical power preferably being provided by generators driven by wind-motors mounted on floating platforms anchored to the sea bed. The evacuated air is exhausted into the space between the pipe 18 and the sheath 15 to keep the sheath inflated. The air is discharged from the sheath through valves 26 which maintain the air pressure at the hydrostatic pressure appropriate to the depth at which the pipeline is to run, whereby the depth is automatically maintained. In addition, the pipeline is supported at intervals by anchored floats which also serve to mark its position.

Title: Improvements in or relating to apparatus for "sampling" liquids
IPC: G01N1/20
Filed: 1931-06-01
Abstract: 379,695. Sampling liquids. KENT, SIR W. G., Biscot Road Works, Luton, Bedfordshire. June 1, 1931, No. 15988. [Class 106 (v).] In apparatus for sampling liquids under pressure the rate of sampling is dependent on the rate of the main flow and the samples are delivered at a pressure at least equal to that of the main flow. As shown applied to the sampling of oil flowing in a main a Pelton wheel or other impeller 1 is mounted in a casing 2 having inlet and outlet branches 3, 4 connected in shunt across a constriction in the oil main. The shaft 5 of the impeller is connected through gearing 20, 21 to a crank 6 coupled by a link 7 to a plunger pump 8 which draws in oil through a pipe 10 and non-return valve 9 from a chamber 11 communicating with the impeller chamber through ports 12 and a strainer 33. The sample is discharged past a non-return valve 13 and conveyed by a pipe 14 to a receiver 15, Fig. 3, filled with water which is displaced by the samples through a valve 16 and pipe 19 the valve 16 being controlled by a piston 17 subjected through a pipe 18 to the pressure existing in the oil main. The gearing 20, 21 and the length of the crank 6 are variable to alter the size of the sample. The valves 9, 13 may be replaced by cork-faced lift valves. An extension 37 of the pump plunger 8 carries a soft iron armature 38 enclosed in a gun-metal casing on the outside of which is pivotally mounted a magnet 39, so that oscillation of the magnet indicates that the pump is working. In a modification the receiver is fitted with a loaded piston which controls the displacement of water past a non-return valve and exerts a pressure greater than that in the main. The use of water may be omitted when the wateroil ratio of the sample is desired.

Title: Improvements in pulley-hoists
IPC: B66D3/16
Filed: 1939-05-31
Abstract: 527,138. Pulley-hoists. MUSUDA, K. May 31, 1939, No. 16085. [Class 78 (v)] In a geared pulley-hoist a clutch 17, Fig. 1, is provided by means of which the reduction gearing 12, 15b, 15a and 9 can be put out of action when it is desired to adjust the lifting chain. The chain wheel 2 for actuating the hoist is mounted on the threaded end 3 of the shaft 1 and can be moved longitudinally thereof to an extent limited by plates 8, 8a. A pawl 6 mounted on the casing 21 engages a ratchet wheel 4 which is mounted on a boss 5 of the wheel 2 between friction rings 7. The chain wheel 13, around which the hoisting chain passes, is rotatably mounted on the shaft 1 and carries the gear 12. The gear 9 is also free on the shaft and is urged against a shoulder 11 by a spring 10. A slidable coupling member 17 keyed to the shaft 1 has three coupling projections 17a, Fig. 4, on one side and a circumferentially disposed coupling member 17b on the other side. These coupling members co-operate with corresponding members 9a, 12a on the gears 9, 12, respectively. A groove on the member 17 receives the forked end of a pivoted arm 18 which is pulled to the right by a spring 20. If no load is attached, or if the load is light, rotation of the wheel 2 in the lifting direction drives the wheel 13 through the shaft 1, coupling member 17 and gear 12. If the load is heavy, the contact surfaces 12a, 17b slip over each other and the member 17 is forced to the left, thereby engaging the projections 9a, 17a and causing the wheel 13 to be driven through the reduction gearing. When the hoisting chain is to be lowered without any load attached, or supporting only a light load, the wheel 2 is rotated in the opposite direction and moves axially until it bears against the end plate 8a. Since the contact surfaces 12a, 17b are again in engagement, the wheel 13 is rotated at the same speed as the wheel 2. If the load runs backwards during hoisting, the reverse rotation of the shaft 1 will cause the wheel 2 to move towards the plate 8 and to be coupled by friction with the ratchet wheel 7. The pawl 6 prevents rotation of the ratchet wheel, and the movement of the load is arrested.

Abstract: 993,164. Photographic processing aparatus. F. BRANTE. April 27,1962 [April 29,1961], No. 16189/62. Heading G2A. In a photographic processing apparatus, two sheets are introduced, together but out of contact, into a developing bath, and then withdrawn in the opposite direction while pressing them together, to effect an image transfer. Fig. 1 shows a suitable device for carrying out the process, comprising an upper part 10, and a lower part 11, which may be inclined as shown. The lower part, which forms the developing bath, is divided into two by a central partition 11a having a tapered upper edge 11b. In the upper part are two rollers 12a,12b, which can be disposed in one of two fixed positions, either in contact, as shown, or else spaced apart (Fig.2, not shown). This movement is accomplished by a lever 13b, on which a set-screw 13f, engaging a pin 14b in the "rollers together" position, can be adjusted to vary the pressure or spacing between the rollers in this position. To use the device, the rollers are set in the "apart" position, and the positive and negative sheets 15a, 15b are lowered into the bath 11, one on each side of the partition. They may be clipped together at their top end, as at 16, to prevent relative shifting. The rollers are now brought together, and the wetted sheets withdrawn from the bath, thus being pressed together to effect the image transfer as they pass between the rollers. In the modification of Fig. 4 (not shown), a lifting device is provided for lifting the sheets out of the bath.
