Title: Improvements in or relating to rotary apparatus for boring earth and rock
IPC: E21B19/08
Filed: 1929-11-01
Abstract: 333,112. Bade, F. Nov. 13, 1928, [Convention date]. Borehole apparatus.-In rotary borehole apparatus of the kind in which compensating means are provided so that as the torque increases the load on the drill is automatically decreased, and vice versa, the compensating means is arranged to act on the free end of the lifting cable, the other end of which co-operates with the drill lifting mechanism.. As shown, the drill is suspended from a sheave B, the lifting cable passing from the hoisting drum E over sheaves C, B, C to a drum F which may have interchangeable rims or be conical or graduated so as to vary the leverage. A hollow shaft 0, carrying a driving pulley M, has a sun wheel L engaging planet wheels K meshing with an internal gear J from which the drill-rotating member G is driven by a bevel gear H. The planet wheels are carried by a bracket N on the inner shaft P on which the drum F is mounted. In use, the weight of the drill normally holds the drum F against rotation and motion is communicated from the pulley M through sun gear L, planet gears K, and internal gear J to the drill; if the torque increases, the planet gears act through bracket N, shaft P, and drum F to increase the tension on the lifting cable and so reduce the pressure of the drill on the ground. In modified arrangements, the drum F is replaced by interchangeable toothed or chain wheels co-operating with a rack or a chain connected to the lifting cable.

Abstract: 1,219,756. Photocopying machines. NIG MASON Ltd. March 22, 1968 [July 19, 1967], No.33259/67. Heading G2A. An original O is fed into a copying machine between conveyor bands 2 and 3, and the copying material CM is fed from a roll R, between rollers 17, 18, and past a cutting device 19, where a length of copy material is cut off which is determined by the length of the original. As the original is carried forward, its leading edge trips the finger 43 of a microswitch 42, so releasing a brake holding the copy material, and engaging a clutch which causes the material to be fed forward. The leading edges of original and copy material meet at the junction point 32, and the two sheets are then carried on, in contact, between bands 23 and 26. As the trailing edge of the original leaves the microswitch finger 43, the clutch is disengaged and the brake operated again, so that movement of the copy material is halted. An electrical pulse is now transmitted to the cutting mechanism, a knife blade 46 descending to sever the copy material. This is conveyed, together with the original, round roller 28 and up again between bands 26 and 34, and then between bands 3 and 38 and guides 44 leading to the copying machine. The roller 28 is vertically displaceable in a guide slot 29.

Abstract: 1,254,351. Desalination of water by distillation; detection of scale formation. COMMISSARIAT A L'ENERGIE ATOMIQUE. 3 July, 1969 [26 July, 1968], No. 33591/69. Headings B1B and B1X. Scale-formation on the heat-transfer surface of a heater wherein a scale-forming liquid such as sea water is heated by a vapour (e.g. steam) is detected by an apparatus comprising a duct 1 for the circulation, via openings 2 and 3, of sea water withdrawn from the heater, a monitoring-tube 4 disposed co-axially within the duct, means for heating the tube 4 so that its surface-temperature is maintained slightly higher than that of the heat-transfer surface of the heater of the distillation plant, and a device for detecting the formation of solid deposit on the surface of tube 4. In a preferred embodiment, tube 4 is made of the same metal as the heater, and is heated by introducing into it, through connection 11 and tube 10, some of the heating-vapour from the heater outlet. Tube 4 is provided with an internal coating of a substance (e.g. gold plating) which promotes condensation, and the vapour partially condenses therein. The condensate flows through tube 18 into reservoir 16; and the non-condensed vapour flows through tube 15 into annular chamber 14. Loop 18a in tube 18 maintains a constant level of condensate in tube 4. The formation of a solid deposit on tube 4 causes an increase in pressure drop within duct 1, and this is indicated by differential manometer 30 which is connected to the duct at three different levels. In other designs, scale-formation can be detected by variations in heat-flow through the wall of tube 4, the temperature of the wall being measured by thermocouple 32; or a change in the rate of flow of condensate into reservoir 16 may be measured by conductivity probes 36 which are connected to an electrovalve 38 controlling discharge orifice 40. Scale-formation in a plant for the desalination of sea water by flash distillation may be detected by the apparatus described. In the case of desalination by means of a multipleeffect evaporator, a detector apparatus could be connected at the outlet of each evaporator.
