Abstract: 1,107,640. Percussive drills. ATLAS COPCO AKTIEBOLAG. 24 Feb., 1967 [2 March, 1966], No. 8851/67. Heading B4C. [Also in Divisions B3 and G3] A rotary-percussive rock drill is supported on a slide 38 movable on a guide frame 45 and provided with a drilling tool 27, means 30, 32 for rotating the tool, and a pressure fluid operated reversible feed motor 48 connected to the slide and adapted to be controlled in either a forward or reverse direction, via a valve 70, in dependence on the torque developed in the rotating means. The rock drill comprises a hammer piston 21 having external splines for connection with a chuck 28 and provided with a nut 29 formed with helical teeth adapted to co-operate with corresponding teeth formed on a bar 30 which is rotatably mounted in the housing 20 of the drill; the bar is provided with a head 32 in which are pivoted pawls 31 for engagement with teeth 33 in the housing. The housing is provided with a knob 59 adapted to engage a plunger 60 mounted in a cylinder 61 which is connected via a conduit 58 with a cylinder 62; a plunger 63 is mounted in the cylinder 62 and is connected to a yoke 84 adapted to operate a pair of spring-loaded ball valves 78 in the valve 70. Conduits 87, 88 lead from the valve 70 to the feed motor 48, pressure fluid being fed into the valve via a conduit 70. In operation, pressurized fluid is fed, via a pipe 24 and valve 26, into the cylinder 22 for the hammer piston 21 thereby causing the latter to reciprocate and rotate the chuck 28 by means of the helical teeth in the bar 30 and the pawls 31; fluid is also fed to the feed motor to cause it to advance the slide 38 via a chain drive 49. In the event of the drill jamming, the reaction, on the rotating mechanism causes the housing of the drill to pivot about bearings 36, 37 so that the knob 59 depresses the plunger 60. Hydraulic fluid in the conduit 58, then acts on the plunger 63 to reverse the position of the ball valves 78 so that the feed motor retracts the slide. In a modification the plunger 60 is mounted directly within the housing and is actuated by means of a lug formed on a member carrying the pawls. In the embodiment shown in Fig. 7, the pawls 31 engage with teeth formed on a ring 33 rotatably mounted in the housing and provided with an arm 100 for engaging the plunger 102; the latter plunger is formed with passages 123, 124 and throttling grooves 121, 122 for controlling the supply of compressed air fed, via a pipe 106, to a servo piston 109 arranged to control the valve 110 connected to the feed motor 48. In a still further embodiment (Fig. 8), the pawl-and-ratchet rotating mechanism is replaced by a separate fluidpressure driven rotary motor (130) connected via a chain-and-sprocket drive (135, 138, 139) to the chuck the reaction between the motor and chuck when a tool jams being transmitted by a lever (141) to a piston-and-cylinder device (145), the liquid in the latter then operating the valve 70 as described with reference to Fig. 1.

Filed: 1941-07-17
Abstract: 550,799. Luminescent materials. ROTHSCHILD, S. July 17, 1941, No. 9074. [Class 39 (i)] Phosphorescent zinc sulphide is prepared by first heating zinc oxide with an excess of sulphur in the presence of halide salts, such as sodium chloride, to about 800‹C, for an hour or longer, with or without admission of air removing particles not showing a blue fluorescence at 460 mÁ, washing with diluted hydrochloric acid and with distilled water. Particles of high density are removed by electrication and the product is then heated with halide salts and compounds of activating metal such as copper chloride to temperatures exceeding 800‹ such as 1,200‹C, with admission of air or preferably in an inert atmosphere, such as nitrogen, finally washing with distilled water. Excess of zinc or sulphur may be added at the second heating. Zinc oxide is prepared by burning pure zinc and collecting the middle part of the subliming oxide, and the sulphur is purified by distillation. The volume of the mixture shrinks to one-third after the first heating, so that more material may be fired at a time during the second heating. Cadmium sulphide may be added to shift the colour from yellow-green (520-540 mÁ) to orange. A detailed example is given. Specifications 495,174 and 495,774, [both in Group III], are referred to. According to the Provisional Specification the heating may be carried out in one operation and the final product may be washed in carbonic or phosphoric acid and in salts of beryllium, Cadmium chloride may be used as a flux.

The conditions of devices at remote positions are signalled to a central station and there indicated on lamps by connecting switches controlled by the devices in turn to a scanner at the central station, which distributes the signals to corresponding indicating lamps. The condition of the device at a remote position is given by lamp 86 which is lit or not. A photo-cell controlled by the lamp operates relay 84 connected in series with contacts 89 controlled by a cam 92 on the shaft of a synchronous motor 75. The motor rotates once a minute stopping after each revolution by cam contacts 76. It closes contacts 89 at a certain time in the cycle to produce a signal on the transmission lines dependent upon the condition of relay 84. The contacts 87 and 89 place a diode 95 across the lines 71, 72 serving to shortout the voltage placed across them. The synchronous motors 75 at the field stations are all started together by a negative pulse provided at the start of the scanning cycle by 4 cam contacts 109, 111 and 112, 113 at the central station. The synchronous motor 99 runs continuously and the negative pulses are received by diodes 94 and coils 82 to operate relays 79 at the field stations, thereby re-starting the motors 75 soon after they have stopped through the opening of contacts 76. The signals in turn applied to lines 71, 72 by the field stations are received in relay 141 and applied through the wiper of switch 106 to the corresponding one of a number of bi-stable transistor circuits 124, each adapted to light a lamp. The lamps are arranged to light if a fault has developed at the associated remote device. The central station has a test switch 134 adapted to operate the relay 141 and light the lamps in turn.
