Title: Hydraulic motors for rock drills
IPC: E21B4/02
Filed: 1970-06-30
Abstract: 1358162 Rotary hydraulic motors W MAYALL 22 June 1971 [30 June 1970 30 April 19711 31751/70 and 12446/71 Heading F1F [Also in Division F2] A motor for a rock drill is energized by drilling mud and has a housing with an end fitting 2 by which it can be fixed to the lower end of a drilling string, bearing sleeves 42, 43, seal structures 44, 105, 112 and bearings 108..111 for rotary shafts 5, 37 being fed with grease from a stationary cylinder 27 by mud pressure acting on a piston 33 through a passage 32. The mud passes down the string and through the housing to the drill by way of a rotary end fitting 8. A valve 10 allows the mud to escape through an opening 17 until its pressure rises to a required value. The grease flows to the sleeves 42, 43 and seal structure 44 between a fixed sleeve 28 and an end cap 38 of the shaft 37, and to the seal structures 105, 112 and bearings 108..111 by way of a bore 41 and tube 106. A vent 127 allows air displaced by the grease to escape. A plug 133 facilitates injection of fresh grease. Mud pressure acting on the seal structures through a passage 58, bore 59 and tube 107 prevents leakage of grease therefrom. A "drive assembly" of the motor includes blades 62 that pivot on studs 63 in a ring 64 against the action of torsion shafts 73 in a rotor member 60, the latter and said ring being attached to the shafts 5, 37. It is indicated (in the Specification) that because each torsion shaft has a portion 76 abutting a wear piece 77 in the member 60 mud pressure in an annular space 80 makes the blades turn so as to bear upon the shaft 37, Figs. 3 and 6 (not shown), and effect continuous rotation of the rotor member and shafts 5, 37. Mud flows from the space 80 to the interior of the shaft 5 through passages 90, 91, 94, the passages 90 coming into register with the passages 91 when the blades approach the shaft 37. The pressure loss at the passages 90, 91 is said to cause the expenditure of energy necessary to drive the motor. A passage 86 equalizes pressures in spaces. (For Figures see next page)

Patent GB-244793-A (GB)
Title: Improvements in and relating to automatic reclosing circuit breaker systems
IPC: H02H3/06
Filed: 1925-12-17
Abstract: 244,793. British Thomson-Houston Co., Ltd., (Assignees of Brown, H. W.). Dec. 17, 1924, [Convention date]. Cut-out arrangements. - In an automaticallyreclosing circuit-breaker system wherein a circuit breaker 3 is arranged to connect a source of current 1 to a load circuit 2 which may, or may not, be taking supply from other sources, for example the generator 10, a polarised relay 19 is employed with a winding 20, for controlling the reclosure in response to the condition of the load circuit, and a magnetizing winding 21 which polarizes the relay in one direction when the single source 1 is supplying and in the other direction when multiple sources are connected. By these means, in conjunction with weak and strong control springs 25, 24 for the different directions of movement of the relay, a higher voltage across the load circuit is necessary to cause the relay to operate when multiple sources of supply are in use than when the single source is connected whereby the single relay 19 can deal with both conditions of supply of the load circuit. The reclosing action with the load supplied only from the single source 1 is as follows. In opening, the circuit-breaker 3 withdraws a short-circuit from a limiting, high resistance, 8 and from a selective relay 27. Owing to the high potential across the resistance 8, the relay 27 closes and short-circuits one arm 28 of a Wheatstone-bridge arrangement of resistances 29, 28, 30, 31 supplied with potential through the contacts 37 of a time-lag relay 35 which is energized through the back contacts 36 of the circuit-breaker. The galvanometer connection of the bridge is taken by the magnetizing or polarizing winding 21 and, with the arm 28 of the bridge short-circuited, the current through this winding is in such a direction as, in conjunction with that through the operating winding 20 which is connected across the voltage of the load, to tend to move the relay arm 40, against the action of the weaker spring, on to the contact 41. This movement takes place when the resistance of the load increases adequately, and the reclosing circuit is completed for the coil 4 through the back contacts 44. When, however, the load is supplied from the additional source 10, the potential of the load circuit at which the reclosing relay 19 operates should be much higher. The action in this case is as follows. The potential across the resistance 8 is now inadequate to operate the selective relay 27, and the bridge is so designed that, with the arm arm 28 open-circuited, the current through the magnetizing winding is in the direction opposite to that in the case frst described, consequently, the arm 40 moves in the opposite direction, that is towards the contact 46 against the action of the strong spring 24 necessitating a relatively high voltage across the winding 20. The reclosing relay may be constructed in the manner described in Specification 182,769.

Title: Improvements in or relating to rocket-launchers for aircraft
Inventor: JOHNSTON ROBERT TAYLOR
IPC: F41F3/06
Filed: 1955-11-08
Abstract: 777,919. Discharging rockets from aircraft. NORTHROP AIRCRAFT, Inc. Nov. 8, 1955, No. 31905/55. Class 9 (2). Rockets are housed in containers 2 fitted in the wings of an aircraft as in Specification 773,656, the rear part of the containers being used for fuel. Openings for the egress of rocket launching tubes 5 are closed by covers 6. Additional rocket tubes may be provided at the forward end 3 of the containers 2 as described in Specifications 777,920 and 775,537. The end 3 of each container comprises two co-axial cylinders 9, 10, the cylinder 9 having spaced openings 13 with covers 6 to which are secured two apertured members 15, Figs. 2 and 4, through which extend the tubes 5. Each member 15 is hinged to an arm 17 which is pivoted on the inner cylinder 10 and is also hinged to a connecting rod 21. Stop 22. 23 on the cylinders 9, 10 respectively limit the movement of the firing tubes and springs 24 return the tube and cover to the closed position. A detent 26 as in Specification 777,920 enters a groove in the rocket to hold it in the tube until fired. A ring 29 carries igniters 30 which contact the nozzles of the rockets 28, electric conductors 31 being used to connect the igniters with a switch (not shown) in the cockpit. Any igniter can be energized at will to fire the associated rocket. On firing, the thrust of the propellent gases causes the tube 5 to pivot on the arms 17 bringing the tube outside the cylinder 9. The thrust is then sufficient to overcome the detent 26 and the rocket 28 leaves the tube 5, after which the cover 6 is restored to the closure position by the springs 24.

Title: Improvements in elevator systems having controlling means giving preference to passengers in the elevator under certain conditions
IPC: B66B1/14
Filed: 1928-09-28
Abstract: 325,894. Waygood-Otis, Ltd. Sept. 28, 1927, [Convention date]. Divided on 297,801. Electric push-button systems.-In a lift system in which the lift is provided with a gate and controls are provided outside the lift for a plurality of floors, and in which when the lift is idle at any one of said floors starting means is responsive to any of the controls for the other floors for causing lift actuating and stopping mechanism to start the lift, means are provided for preventing the response of said starting means to the controls for said other floors for a predetermined time interval after the closing of the lift gate. Fig. 2 is a simplified diagram of the power and control system described in Specification 297,801. When a passenger enters the lift, the platform switch contacts 29, 39 and 48 separate and upon the release of the door, it closes and causes the re-engagement of the door contacts 53. Since contacts P67, P69 are separated as well as the contacts 29, 39, control of the lift cannot be taken away from the passenger. When the gate is closed the gate contacts 62 engage to bye-pass the contacts 48 and complete the circuit for the coil R 55 of the auxiliary lift preference time relay. This relay operates to break the circuit for coil P65 of the lift preference time relay. The contacts P67, P69 of this relay do not engage immediately since the action of the relay is delayed by a timing arrangement, such as a dashpot. This delay is sufficient to allow the passenger in the lift to select his destination without the possibility of interference due to the pushing of floor buttons.
