Title: Improvements in grinding and polishing apparatus
IPC: B24B21/00
Filed: 1967-04-14
Abstract: 1,148,825. Grinding. METABOWERKE K.G. CLOSS, RAUCH & SCHNIZLER. 14 April, 1967 [27 April, 1966], No. 17137/67. Heading B3D. A grinding or polishing apparatus comprises either an abrasive belt 44 conducted over a contact wheel 10 and tensionable by means of at least one tensioning roller 19, or a polishing wheel, the contact wheel or polishing wheel being arranged on a limitedly movable holder 9 mounted on a carrier part 1, the pressure application force of the contact or polishing wheel at the machining position being kept at least approximately constant with different height positions of the wheel in relation to a workpiece support surface. When the apparatus includes the abrasive belt, the holder 9 carries the contact wheel 10 at one end and is mounted on a pivot 38 on the carrier part 1, the lever having an extension 11 connected to one end of a spring 14, the other end of which is secured to the carrier part. A bracket 34 is connected to the lever 9 and to an air cylinder 36 which, with the spring, acts to press the contact wheel against the abrasive belt. The belt is entrained about a pulley 7 on the pivot 38, a pulley 6 driven by an electric motor, and the tensioning roller 19. The latter is mounted on one arm 18 of a two-armed lever 17, the other 20 of which is connected by a spring 23 secured to a sleeve 24 adjustably positioned on an arm 15 carrying the part 1. A rod 25 articulated to the sleeve 24 and having notches engageable by a bolt 27 at the end of a lever 28 permits adjustment of the tension in the spring. A rod 30 between the arm 18 and lever 28 effects raising and lowering of the tensioning roller 19 upon movement of the lever to tension the abrasive belt or permit its removal from the apparatus. The arrangement of the levers 9, 17 and springs 14, 23 is such that the contact wheel 10 applies a constant force to the abrasive belt during vertical movement over a workpiece and the tension in the belt remains constant. The cylinder 36 can be actuated to supplement the springs. The spring 14 may be connected to the extension 11 on the other side of the centre line of the lever 9. When the apparatus is used with a polishing wheel, the contact wheel is replaced by a polishing wheel 50, Fig. 7, and the pulley 7 is replaced by a pulley which is driven by a motor and connected by bolts to the polishing wheel. The workpieces may be carried by a conveyer belt.

Title: Improvements in and relating to reciprocating pumps
IPC: F04B3/00
Filed: 1926-07-08
Abstract: 278,442,. Marquet, E. July 8, 1926. Cam-actuated pumps; regulating delivery by opening and closing suction and delivery valves; valves, arrangement of.-A pump comprises a rotating cylinder A with an inclined end surface engaging a sliding piston B with a similar end surface. Rotation of the cylinder A causes the piston B to move to the left so that liquid is drawn into the space between the inclined surfaces through an inlet port O controlled by the cylinder A. The delivery stroke of the piston is effected by a spring &c. R, the liquid being delivered through another port 0 controlled by the cylinder A. The piston is prevented from rotating by a fixed pin C engaging a slot D in the piston. By angularly adjusting the piston relatively to the cylinder A, the output may be varied from maximum to zero. By adjusting the piston through 180‹, the direction of rotation of the cylinder A may be reversed without changing the direction of flow of the liquid. A doubleacting form comprises two cylinders A on the same shaft and a piston with the inclined ends between them. Specification 148,560, [Class 111, Sewage &c.], is referred to.

Title: Control system for hydrofoil craft
IPC: B63B1/28
Filed: 1973-04-10
Abstract: 1381436 Hydrofoil craft; stabilizing BOEING CO 10 April 1973 [31 Oct 1972] 17204/73 Headings B7A and B7M A hydrofoil craft is caused to begin to bank automatically about its roll axis 60 before turning about its yaw axis 64 in response to the helm. The craft has forward and aft foils 16, 26, at least one having separate port and starboard flaps, e.g. 28, 30, 32, 34, and means for generating a command signal for turning the craft. Further means respond to the command signal to actuate the separate flaps 28-34 to cause the craft to bank in the direction of the desired turn. This banking is then sensed by means to which is coupled apparatus for actuating the rudder. As shown in Fig. 5, the craft is equipped with various sensors (left hand side) which are located as indicated in Fig. 2 which is a view from below the craft. When it is desired to turn the craft about its yaw axis 64 a turn signal from helm 72 is fed via line 70 to an amplifier 80 which compares the turn signal with the roll signal from the vertical gyro 44 and produces an output dependent on their difference to operate flaps 28-34 which cause the craft to roll. The roll continues until the roll signal from gyro 44 is large enough to null the signal from helm 72. At the same time, the signal on line 82, proportional to the roll angle, is applied to the rudder servo 92 to operate the (forward) rudder 12. Signals from the yaw rate gyro 45 and the lateral accelerometer 38 are also applied to rudder servo 92 to limit its effect. Stabilization.-Forward flap 18 is actuated to counteract pitching, by a signal which is combined, in amplifier 100, from a signal from the forward accelerometer 35 and a signal from circuit 98 proportional to the roll signal squared. (This is because rolling produces a vertical acceleration component.) In addition, pitching is counteracted by the operation of all the flaps by signals from the vertical gyro 44. Roll is counteracted by the roll signal from gyro 44 being fed alternately to the port and starboard servos 84, 86 and 88, 90. Heave is counteracted by signals from port and starboard vertical accelerometers 42, 40 being applied to port and starboard flap servos 84, 86, and 88, 90, respectively. Craft construction.-Forward foil 16 and rudder 12 are pivotable in a forward and upward direction to a position suitable for hull-borne operation. Similarly the aft foil 26 is mounted between two legs 20, 22 which are pivotable about 21 upwardly and to the rear. Propulsion.-The vessel may be provided with a screw propeller for hull-borne propulsion and a separate screw propeller or water-jet installation for foil-borne propulsion.
