In a mineral-mining plough the shank 20 of each wedge head 15 is so slidably mounted in the body of the plough that on the head encountering an abnormal resistance to its penetration of the mineral it moves backwards against a resilient resistance provided by spring means 19 positioned between the head and the body so that a shoulder 21 engages a plunger 22 of a valve regulating a valve controlling a pneumatic hammer mechanism. Engagement of the plunger 22 by the shoulder 21 operates the first valve to cause it to permit the passage of air to open the second valve thus setting the hammer mechanism in operation to strike blows on the shank 20. When the abnormal resistance has been overcome the head 15 is by the springs 19 sufficiently advanced to permit of disengagement of the shoulder 21 and plunger 22 so that operation of the hammer ceases. To prevent ingress of dirt into the body a pad 31 of resilient material, e.g. hardened natural or artificial rubber, is bonded between two flanges 32, 32 bolted to the body and wedge head respectively. The portion of the shank having a sliding fit in the body may have a non-circular cross-section. Specification 717,033 is referred to.

Abstract: 777,939. Dictating over telephone lines. UNILEVER, Ltd. Oct. 27, 1954 [Nov. 10, 1953], No. 31113/53. Class 40 (1). [Also in Group XXXIX] In a system in which a remote dictating machine is controlled from sub-stations by transmitting to it currents of frequencies dependent on the desired condition, a common signal-current generator is provided at a central point and injects into the control circuit a current comprising all the control frequencies as components, or a succession of currents of the different control frequencies, via a selected one of a set of tuned impedances at the calling sub-station. As shown, a call for the dictating machine is switched through at 6 to the control apparatus by an operator, though automatic operation is mentioned. The subscriber, hearing a 400-cycle signal from an oscillator 17 operates his " record " button 53. Current of 7 kc. from oscillator 201 then finds a path of reduced impedance at the sub-station and the resulting increase of the input amplitude at tuned amplifier 9 releases relay A. A shunt is then removed from E which operates (C being normally energized), switches the speech circuit through to the dictating machine and conditions the latter to record, and opens a point in the shunting circuit to prevent its own release on the re-operation of A when the control button is released. Operation of the " stop " button similarly releases B which shunts itself and so remains back when the button is released. " Play back " is initiated by the release of C which causes the relapse of E also and the re-operation of B to switch the talking circuit to the play-back terminals and re-start the machine. F also operates in a self-interrupting circuit and sends impulses over wire 21 to stepback the recording head until the button is released. To call the operator, A and C are released simultaneously and D pulls up releasing B to stop the machine and operating a buzzer. Specification 776,264, [Group XXXIX], is referred to.
