Each ram assembly is provided with an extension head 14 which is attached to the ram by way of an angled coupling unit 18 and which is turnable to permit variation in the angular orientation of the extension head with respect to the ram. Each extension head is provided with an angle head 27 which is angularly swingable with respect to the extension head and which carries a milling cutter 5 the angular locating movement of the angle head permitting further angular orientation of the milling cutter with respect to the extension head. Drive means in the form of drive shafts and bevel gearing is provided to transmit the drive from the ram shaft to the milling cutter. The angular movement of the angle head with respect to the extension head may be effected manually by way of shaft 28 and bevel gears 28 1  or alternatively by way of a motor 14 and a pinion 30 and ring gear 31. Similarly the rotation of the coupling units may be effected manually by way of shaft and worm gear 18 1 . Fluid actuated clamping means (not shown) is provided to clamp the angle head to the extension head and a further fluid actuated locating means 40 is provided to engage the ring gear teeth 31 on the angle head to prevent backlash between the gears 30, 31. In operation the propeller 1 to be machined is mounted on a turntable 6 beneath the bridge structure, the angular orientation of the milling cutters being adjusted by way of the coupling units and angle head to achieve the desired pitch and rake angles of the propeller blades, the setting of the milling cutters may be done manually or automatically which permits the propeller to be accurately machined under numerical control. In addition to the milling cutter secured to the angle head an end milling cutter may also be attached to the opposite end of the extension head to facilitate the machining of the outer periphery of the propeller hub.

Title: Control device for pebble-bed nuclear reactors
IPC: G21C7/107
Filed: 1969-12-19
Abstract: 1,236,330. Controlling reactors. BROWN BOVERI/KRUPP REAKTORBAU G.m.b.H 19 Dec., 1969 [20 Dec., 1968, 13 Sept., 1969], No. 62148/69. Heading G6C. A control device for regulating a pebble-bed nuclear reactor comprises an absorber rod 6 mounted for rotation about its longitudinal axis, and for longitudinal movement in the direction of the axis, whereby to penetrate the reactor core and to displace some of the elements of the core, the rod 6 having at least one helical groove 6<SP>1</SP> formed in its exterior surface at least over that part of its length which penetrates the core. As shown, the device comprises a drive shaft 2, the lower part 3 of which takes the form of a splined shaft which passes through a sliding ball bush 4 connected to an axially displaceable tubular member 5, to the lower end of which is connected the rod 6. Slip couplings 7, 8 on the periphery of the tubular member 5 can be engaged/ disengaged according to the direction of rotation of the member 5. Coupling 7 may be directly connected to a lifting screw 9, the square thread 10 of which engages in a counterthread formed by ball-bearing rollers 11 fitted on the inner circumference of a casing 1. Coupling 8 engages in one end face of a coaxial intermediate member 12, at the other end face of which is a planetary gear 13 connected to the lifting screw 9 in a mechanically positive manner. For the purpose of indicating the position of the rod 6 an impulse transmitter is fitted on the stub of the drive shaft 2 protruding from a motor 17. When the rod 6 is being driven in to the reactor core, the rotary movement of the lower part 3 of the drive shaft 2 is transmitted directly to the sliding ball bush 4, which transmits the rotation to the tubular member 5 and the rod 6. A longitudinal movement takes place simultaneously by way of the engaged slip coupling 7. When the direction of rotation is reversed, the rotation is transmitted through the bush 4 to the tubular member 5 and the rod 6 as before. The transmission of torque to the lifting screw 9 now takes place by way of the other slip coupling 8, which operates in a direction opposite to that of coupling 7, and by way of the intermediate member 12 and the planetary gear 13, which directly meshes with the screw 9. The provision of gearing between the intermediate member 12 and the screw 9 allows different travel ratios (i.e. ratio of the speed of movement of the rod 6 to the lifting speed of the screw 9) dependent on the direction of rotation of the motor 17. The rod 6 may comprise a carrier tube which is surrounded by a layer of neutron-absorbing material. This layer may in turn be surrounded by an outer tubular jacket of heat-resisting steel. At its end which enters the reactor core, the outer jacket is conveniently tapered or pointed. The groove(s) 6<SP>1</SP> in the outer surface of the jacket may be trapezoidal in cross-section. The rod 6 is solid apart from a central passage through which a coolant may be passed into the reactor core through a suitable disposed orifice.

Title: Method of and apparatus for measuring distance between two transmitting stations
IPC: G01S13/84
Filed: 1978-08-01
Abstract: A distance measuring system includes a ground station transponder continuously transmitting a repeating pseudorandom coded bit pattern, and at least one aircraft interrogator receiving, locking onto and repeating the ground station signal. The aircraft interrogator transmits a coded interrogation signal in precise synchronism with an identically coded with an arbitrarily selected any one of the code words in the repeated ground station signal and waits for a reply. If the ground station receives the coded interrogation signal in synchronism with an identically coded word in its continuous transmission, it transmits a reply signal to the aircraft interrogator optionally encoded with synchronism error or interrogation steering information. If no reply is received by the aircraft interrogator, it transmits its next coded interrogation signal shifted by one or more bits relative to said selected code word. Successive interrogation signals are shifted an additional predetermined number of bits until synchronism is attained and a reply signal is received. The number of bits of shifting performed by the aircraft needed for synchronization when combined with the number of bits representing the whole code word intervals elapsing between transmission of an interrogation and receipt of a reply represents the distance between the ground station and aircraft.

Title: Method and Apparatus for Analyzing Ionizable Materials
IPC: G01N27/06
Filed: 1978-11-30
Abstract: An apparatus and method for analyzing a solution of ionizable compounds in a liquid comprises irradiating the solution with electromagnetic radiation to ionize the compounds and thereafter measuring the electrical conductivity of the solution. The radiation may be X-rays, ultra-violet, infra-red or microwaves. The solution may be split into two streams, only one of which is irradiated, the other being used as a reference by comparing conductivities of the two streams. The liquid must be nonionizable and is preferably a polar solvent. The invention provides an analysis technique useful in liquid chromatography and in gas chromatography after dissolving the eluted gases in a suitable solvent. Electrical conductivity measurements performed on the irradiated eluent provide a quantitative indication of the ionizable materials existing within the eluent stream and a qualitative indication of the purity of the eluent stream.
