Title: Improvements in or relating to steering devices for ships and the like
IPC: B63H25/38
Filed: 1920-07-07
Abstract: 174,023. Flettner, A. July 7, 1920. Addition to 174,022. Rudders; steering-gear.-Relates to steering- devices wherein an auxiliary rudder mounted on the main rudder is employed to produce or assist in deflexion of the main rudder and wherein, as in the invention described in the parent Specification, the main rudder is free to swing on its axis through 180‹ when the ship reverses its direction without disconnection of the actuating- gear of the auxiliary rudder, and comprises an improvement in or modification of the parent invention in arranging for a pendulum motion of the auxiliary rudder on its axis during such reversals. The freely-mounted main rudder 126 carries a frame 137 on which is mounted the gearing between the electric motor 130 and auxiliary rudder 127. The motor drives through irreversible worm gearing a pinion 135, which gears with a pinion 136 provided with a crank-pin 138 which engages a slot in and reciprocates a frame 140. This frame has a rack 141 which drives a pinion 142 on a shaft passing down the hollow spindle 128 and thence by gearing to the auxiliary rudder. The auxiliary rudder is therefore capable of actuation by the motor 130 within the usual limits of angular movement for steering. When the latter is inoperative and the main rudder reverses on the ship reversing, the pinion 135 is fixed and the pinion 136 rolls around it, thereby reciprocating the frame 141 and giving the pinion 142 and the auxiliary rudder a to-and-fro or pendulum-like motion. The gear ratio is such that the two rudders are aligned in the fore and aft direction when reversal is completed. The gear box may be disposed within the rudder.

Patent GB-852573-A (GB)
Title: Improvements in cement manufacture
IPC: C04B7/45
Filed: 1956-11-08
Abstract: Cement is manufactured by feeding the finely-powdered ingredients into a fluidized bed of larger-sized particles of finished cement which is maintained at a temperature sufficiently high to cause the ingredients to react and to accrete on the finished particles.  The temperature of the bed is maintained by the combustion of fuel into the bed, and some at least of the air employed for fluidizing the bed may be preheated.  Part of the bed is continuously withdrawn and is fed to a cyclone separator from which the coarser particles are discharged but the finer particles are carried along by the air stream back into the fluidized bed. The gases generated in the bed escape from the top of the bed and any entrained particles are separated and recycled.

Title: Transfer mechanism
IPC: B65G47/64
Filed: 1976-08-17
Abstract: 1530826 Transferring articles between conveyers R A JONES & CO Inc 17 Aug 1976 [18 Aug 1975] 34250/76 Heading B8A Groups 13 of pouches are fed from poucher machines 10, 11, to a conveyer system 22. The latter comprises two side-by-side pairs of conveyer assemblies mounted to pivot about a point adjacent their upstream ends, so that their downstream ends can match the speed of a bucket conveyer 23 which leads the pouches to a cartoner machine 24. Each conveyer assembly comprises an upstream belt conveyer 63 (Figs. 2 and 3), and a downstream belt conveyer 69. The upstream ends of both conveyers travel around a common drive axle 58, but the upstream conveyer 63 is shorter than the conveyer 69 (turning around an idler shaft 57). A roller and stop assembly 100 has an initial position (Fig. 3) in which a roller 101 lifts the belt 63 above the normal common working level of the two belts 63 and 69 and by this means a leading pouch group is brought up to and momentarily held against movement by a stop 110. The stop assembly 100 is then moved to its other position (Fig. 2) in which the belt 63 is released, the belt 69 is lifted, and the stop 110 is retracted. The held-up articles are thus picked up by the belt 69 and their spacing is increased, because the belt 69 moves faster than the belt 63. At the downstream end of the belt 69, each pouch group is successively halted by a stop 125 (lifted and lowered by action of a cylinder 124) and then is fed to a respective bucket 42 as the downstream end of the conveyer system 22 moves parallel with the conveyer 23. This action is brought about by a cam mechanism (Fig. 6, not shown). The latter mechanism and the conveyers of the system 22, are driven by gearing in synchronism with the cartoner (Fig. 4, not shown).

Abstract: 874,394. Dynamo-electric machines. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. Nov. 7, 1957 [Nov. 7, 1956; Feb. 21, 1957; June 14, 1957], No. 34792/57. Class 35. [Also in Group XXXVI] In a multi-polar electrical rotating machine having a discoidal rotor member and a stator member separated by a substantially flat annular air-gap, one member comprises magnetic material and the other carries a plurality of conductors constituting a winding formed by a printed circuit technique and a face of which substantially bounds one side of the air gap. In the A.C. machine shown in Figs. 1 and 2 a discoidal rotor 1 of magnetically soft steel or hysteretic steel (for induction or synchronous motors respectively) or of a copper-iron composition obtained by sintering powders or mechanically coating, is mounted at 2 on a shaft 3 supported by bearings 6 in two half-shells 4, 5 containing stator annular discs 7, 8 of magnetic material e.g. sintered iron powder and around which magnetic laminated ribbons 10 may be wound. Printed in machined or moulded radial slots in the discs 7, 8 are windings 9 forming eight poles per phase in single- or two-phase machines, and the poles of the two discs are either in mutual registration or in a modification half a pole pitch apart. Intervals between the conductor turns may be made flush with an insulating filler e.g. a colloidal iron deposition, and each disc may carry a number of superimposed sandwiched printed windings. In the A.C. or D.C. machine shown in Figs. 8 and 9, e.g. A.C. generators or rotary converters, a rotor dielectric disc 11 carries on its two faces printed series wave windings 12 having radial operative portions 13 and inclined end portions 14, 15 interconnected at 34 by pressing together indium ring coatings electrodeposited on copper foils glued to the disc and which are subsequently photo-etched to form the winding. The stator comprises a magnetic ring 18 carrying permanent magnets 16 having pole shoes 17 and the magnetic circuit is completed by a magnetic disc 19 secured either to the stator or as shown to the rotor. The magnet field may be varied by a magnetic shunt ring 28 supported by posts 29 carried by a plate 30 which is axially adjustable by a screw 31 and knob 33. Brushes carried by spring-loaded mountings 27 bear on the winding inclined parts 14 or 15.

Abstract: 389,205. Combined valve- and siphondischarge water - waste preventers. McNAMARA, S. B., Troutstream Way, Loud water Estate, Rickmansworth, Hertfordshire. Dec. 16, 1931, No. 34845. [Class 26.] A siphon-discharge waterwaste - preventer of the type in which a valve 16, Fig. 1, for controlling the flush is arranged in the outlet pipe 4 and below the level of the cistern 1, the valve is operatively connected to a piston or a diaphragm 12 and the opening of the valve causes a vacuum to be formed in a chamber 14 whereby the valve is retained in the open position. In the form shown, the valve and diaphragm are connected by a pipe 10 which also carries a bell 9, and when a lever 30 is depressed to lift the valve from its seat, water previously trapped in the pipe 4 is released to start the siphon and evacuate the chamber 14 through a shielded aperture 19. The valve is restored by the entry of air into the pipe 10 through a pipe 15 which is normally closed by a disc 15f, Fig. 2, on one of two cups 15a, 15b carried by a pivoted arm 15c. When the water-level falls below the end of the tube 15, the cup 15b, which is normally full of water, is emptied through the aperture 15g, and becomes lighter than the cup 15a which falls and admits air to the pipe 15. The valve-box 8 is divided into two compartments by a partition 23 in which the valve-aperture 24 is disposed ; further, the lower compartment has three openings 25, 26, 27 either of which may be connected to the flush-pipe 28. The tube 10 and the bell 9 may be counterbalanced, the bell may be replaced by a siphon tube, and the lever by a bell crank operated by a Bowden wire ; further, admission of air to the pipe 15 may be controlled by a float-operated sleeve on the pipe. According to the Provisional Specification, the operating-rod of the valve passes through a bush in a U-shaped siphon and is connected to one end of a pivoted lever connected at the other end to the piston of a, piston-and-cylinder device for restoring the valve.

Abstract: 1319904 Programmed control of machine tools BENDIX CORP 26 July 1971 [6 Aug 1970] 34874/71 Heading G3N A stored programme numerical control system, wherein a programmable digital processor determines data transfers for control of the position of a mechanism, is responsive to interrupt subroutines of a control programme to carry out the transfers according to a predetermined order of priority. As shown a tool 12 is positioned by X and Z axes servos 14, 16 controlled via - resolvers 150, 160 from command counters 146, 156 fed from D.D.A. interpolators 52, 54. The interpolators are serviced by a digital processor 18, incorporating a non-volatile memory 20, on an output bus 26. The sequencing of data transfer requests to the processor is determined from signals on a line 24 and  system data received on a bus 22. The processor operates in a priority - interrupt mode, the first priority being a tape reader 28 setting in BCD coded part - program data from a punched plastics tape 30, into the memory 20. The second priority is a clock unit 40 providing from oscillator 42, divider 44 and reference counter 46 calling up a service routine to perform a data transfer. The third priority is for the interpolators 52, 54 which call-up and receive partprogram data from the tape and produce corresponding command pulses of a desired rate. The fourth priority is for push buttons 66 on a control console for manually operating the tool. Associated with the push-buttons are thumb-wheel switches 80, setting in data such as feedrate to which no interrupt priority is allocated. The processor also drives a status display 82. The interrupt signals on line 24 are only accepted by the processor when a service subroutine is not being executed. This is arranged by connecting line 24 through an AND-gate 96 held closed by a flip-flop 98 during transmission of signals on the output bus 26. Data on the input bus 22 is also provided from actual position counters 106, 108. A counter 124 is fed from an external clock'and when not reset from a command on the bus 26 in a specific time, actuates an alarm 130. The output from the processor also includes inches per revolution data, fed to a device 132 which modifies the action of a feed-rate control 134 for the interpolators. Provision is made for the display of tool offset 120, sequence 122, and position 118.
