Title: Source of sublimable material
IPC: H01J7/18
Filed: 1971-03-24
Abstract: 1386251 Ion pumps; gettering discharge apparatus BRITISH OXYGEN CO Ltd [trading as EDWARDS HIGH VACUUM INTERNATIONAL] 21 March 1972 [24 March 1971] 7745/71 Heading H1D A source of sublimable material suitable for sublimation pumps (e.g. REF pumps), includes a longitudinal sublimable body 20 (e.g. Ti or Ti alloy) spaced axially and radially from a non- sublimable housing 22 (e.g. of Ta or Ta alloy, Mo or other refractory metal), and means for heating the housing, the housing having perforations 26 distributed angularly and longitudinally through which sublimed material passes. Heating of body 20 by radiation reduces hydrocarbon formation. Housing 22 may be electron heated (in REF pumps) or Joule heated. In the latter case, body 20 support is insulated from the housing. Rod 2 may be of alumina, and shield 22 electroresistive, perforations 26 preferably being transaxial slots overlapping longitudinally, the metal being of serpentine form. The perforations may be replaced by a helical slot and may be formed by the spaced apart edges of a strip of helically wound electroresistive material. The housing may alternatively be frusto-conical or other contoured shape. Preferably end caps 24 are also non-sublimable material. Perforations may cover 10-20% of the area for example, and may be shaped as in a grater, preferably in opposite directions on each side of a central plane to ensure deposition over a larger area and also more uniformly. Patterning of the perforations 26 may also affect operation. Fig. 1 (not shown) is an REF pump with anode (2), a water cooled housing acting as earthed cathode (4), reflector (12), filaments (16), one or both being heated, and supports (14) preventing electrons falling on anode (2). Electron orbits may be circular or elliptical crosssection.

Title: Improvements in lock nuts
IPC: B23P13/02
Filed: 1924-03-27
Abstract: 213,902. Furlan Nut Machinery Corporation, (Assignees of Furlan, J. G.). April 2, 1923, [Convention date]. Turning.-In a method of producing lock-nuts of the kind wherein two groups of threads are in axial alignment but are displaced axially out of helical alignment the thread is separated by an annular groove into two sections and lateral pressure is applied to the groove to displace one section axially relatively to the other. As applied to a turret lathe, Fig. 1, bar stock 4 from which nuts are produced is fed against a stop 6, after which a drill 7 and a tap 8 are brought into operation. The groove 11, which has inclined sides, Fig. 4, is then acted upon by an expanding tool 9 which consists of rollers 10, Fig. 2, carried by levers 15 and pressed into engagement with the work by a wedge 12 introduced between adjustable screws 14. The wedge is carried by a cross-slide 13, Fig. 1, which also carries a forming tool 16 so that when one nut is being expanded the next nut is being grooved and chamfered. Finally a tool 18 cuts off the expanded nut. The rollers 10 engage the inclined sides of the groove 11 and deform these axially to the shape shown in Fig. 5 so that the diameter of the thread remains unchanged. The groove 11 may be cut before or after screwing and the steps of the method may be performed independently. Tools.-The Specification as open to inspection under Sect. 91 (3) (a) comprises also a similar method of making lock-bolts. Fig. 13 (Cancelled), the sequence of operations being similar but the grooves 11 being produced by the form-tools shown in Figs. 8 (Cancelled) and 12 (Cancelled) and the rollers acting on the bottoms of these grooves. This subject-matter does not appear in the Specification as accepted.

Abstract: 635,238. Grinding turbine-blades and the like. FAIREY AVIATION CO., Ltd., and LYON, G. March 25, 1947, No. 8118. [Class 60] [Also in Group XXII] The profile-generating machine of Specification 634,387 is modified by arranging for rotary movement to be imparted to the tool mounting by the action of a cam 275 on one end of a lever 271, the other end of which is formed as an arcuate rack meshing with a gear-wheel 268 rotatable in bearings on the arm 31 carrying the tracer and tool mountings. In addition, the point at which the pitch circles of the arcuate rack and the gear-wheel have a common tangent lies on the axis of the pivot from which the arm is suspended, and the gear-wheel is arranged to turn the shaft of the rotary mounting for the tool. The tracer mounting is rotated from the tool mounting by means of tapes' 293 ... 296 secured to drums 102, 292 on the tool and tracer shafts, the free ends of the tapes being connected by tie-rods 297, 298 which are adjustable in length to allow variation in the position of the tracer mounting on the arm. Alternatively, the tracer mounting may be rotated from the tool mounting by toothed gearing. One end of the lever 271 is bifurcated to carry a roller 274 held in contact with the cam by a hydraulic jack 281 connected with a source of fluid pressure and pivotally mounted on the carriage 33 which also carries the pivot for the lever. The cam 275 is counterbalanced by weights 289 and mounted on a shaft 276 driven through worm gearing at half the speed of the shafts which effect reciprocation of the master form and oscillation of the work. The shaft 276 is journalled in a carriage 277 traversed by a lead-screw 285 driven by gears which are so chosen as to cause traverse of the cam at any desired proportion of the speed of the carriage 33. The cam varies in section from end to end correspondingly with the variation in the master form. The driving means for the carriages are arranged for connection with means for effecting a quick return movement. The axis of the motor for driving the tool spindle is in alignment with the axis of oscillation of the arm. Specifications 606,620, [Group XXIX], and 633,550 also are referred to.
