Abstract: 990,208. Welding by fusion. BOHLER & CO. A.G. GEB. Nov. 20, 1962 [Nov. 25, 1961], No. 43800/62. Heading B3R. An arc welding process utilizes grouped pairs of partly coated electrodes, the electrodes of each pair being supplied with welding current and brought together adjacent the welding zone to form an electrode coated on all sides. Carbon dioxide shielding may be used. The pairs of electrodes, 1, 2, 3, Fig. 1, may be located in line with or transverse to the welding direction. The cores and coatings of any or all of the electrodes may be the same or different. Thus, e.g., electrodes having cores of nickel and iron may be used to produce a deposit of 50% iron and 50% nickel. The leading pair may have a calcium carbonate based coating and the trailing pair may have a rutile base coating. For welding V-shaped grooves, the electrode pairs 7, 8, 9, Fig. 3, are of increasing size, the smallest pair 7 forming the root weld. Also a group of electrodes may be pivotally oscillated about the axis of the leading pair. The electrodes of a pair or the pairs of electrodes may be fed at different rates. The coatings of the electrodes may be thickened adjacent the plane of contact so that each pair of electrodes has flat sides. Strips 14, Figs. 11, 12, may be fed between pairs of electrodes or between electrodes of a pair. The strips 14 are of iron, alloying metal or flux.

Abstract: 973,504. Parametric amplifiers. RADIO CORPORATION OF AMERICA. Dec. 20, 1960 [Jan. 4, 1960], No. 43814/60. Heading H3B. In a parametric amplifier, pumping, signalling and idling waves are transmitted on one or more helical transmission lines. The individual terms of each helix are connected to variable capacitors in the form of semi-conductor junction diodes which may link successive turns of the same helix and may link adjacent turns of different helices. Tunnel diodes may be used. Single helical transmission line.-A signal from source 14, Fig. 1, is transmitted as a wave on a helix 27 of tungsten wire plated with copper or silver. The wire is wound on an insulating support which may be a cylinder 24 or a framework 36, Fig. 4. The pump source 18 is coupled to the helix by a coil 34. The signal, pump and idler waves travel at the same velocity, and a filter 22 accepts only the signal wave. A diode strip 28, Fig. 3, comprises a backing strip 29 of metal or quartz and a strip 30 of N-type germanium on which are fused dots 31 of P-type indium. Each successive turn of the helix is coupled to an indium dot by fusion, by contact or by capacity through a thin insulating layer. Three diode strips 28 are coupled to the helix 27 as shown, but any number of strips may be used. The diode strips 28 are mounted on the helix by ceramic insulating rings 32, 33. Ferrite rings 35 absorb reflected waves in the helix. The helix is mounted in a metallic casing 10. In a modification, Fig. 5, the diode strips 40 each comprise a number of bodies 42 of N-type germanium and a number of dots 43 of P-type indium connected alternately in series to a ceramic backing strip 41. The pumping wave may be fed to the helical line 27 by a number of coupling coils 34 distributed along the line. Separate helical transmission lines.-Separate helices 95, 96, 97, Figs. 8, 9, carry the signalling, pumping and idling waves Fs, Fp, Fp-Fs. The helices are coupled in pairs by diode strips 107,108, 109 and are each dimensioned so as to support only one of the three waves. The three helices 115, 116, 117 may be coupled by a single diode strip 118, Fig. 11, and may be screened by a wire mesh 121.

Title: Machine-tool displacement measuring
IPC: G01D5/38
Filed: 1967-10-03
Abstract: 1,205,446. Position finding. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 3 Oct., 1967 [6 Oct., 1966], No. 44895/67. Heading H4D. [Also in Division G1] In a machine tool control system in which the image of a fixed grating is projected on to a movable grating connected for movement with the machine tool and in which the image is given a periodic lateral motion by reflecting the image beam in a rotating light-reflective polyhedron, the reflected beam is bifurcated to produce two relatively reversed images on a movable grating. As shown light from a lamp 1 is reflected at a fixed curved mirror 2 and impinges on a fixed grating 4. The image formed by the light passing through this grating passes through a pair of lenses 3 and 6 and a semi-transparent mirror 5 and is reflected in a rotating polyhedron 7. The reflected beam passes back through the lens 6 and is reflected by the semi-transparent mirror 5 towards a mirror 8. Half of this beam misses the mirror and impinges on the movable grating 9 where it is reflected on to a photo-cell 11, while the other half is reflected at the mirror 8 and is reflected by the movable grating as at C, D on to another photo-cell 10. While the grating 9 is stationary the two images A, B and C, D of the fixed grating appear to move in the direction of the arrows with a velocity proportional to the rate of rotation of the polyhedron 7. The frequencies of the resulting pulsating outputs of the two photo-cells being equal. If the grating 9 is moving it adds to the apparent velocity of one image and subtracts from the other. The resulting difference in frequency in the outputs of the two photo-cells 10 and 11 is proportional to the velocity of the grating 9 and thus of the machine tool and is independent of irregularities in the polyhedron 7. The displacement of the grating can be derived from the difference in phase of the two outputs. In another form (Fig. 2, not shown) a semi-transparent mirror formed of two plane parts at an obtuse angle to each other are used. These two parts additionally split the beam into two paths one either side of a vertical plane through the system and extending at 45 degrees to the plane. In each of these paths is a detector arrangement generally similar to that formed by the components 8 to 11 except that two internally reflecting prisms replace the mirrors 8 and a single point grating 9 is used for both arrangements. Thus movements in two perpendicular directions can be measured.

Abstract: 1,203,615. Separating sheets. RANK XEROX Ltd. 5 Oct., 1967 [11 Oct., 1966], No. 45383/67. Heading B8R. A pile table for use in sheet-feeding mechanisms comprises retaining means for supporting a stack of sheets, means for raising and lowering the stack in response to switch means, and sensor means co-acting with the topmost sheet of the stack to actuate the switch to raise the stack when its hoist falls below a predetermined level, the sensor means being adjustably mounted on an oscillatory member. The invention is illustrated with respect to a xerographic machine in which the pile table is raised or lowered by a pulley and cable system driven by an electric motor controlled to raise the table by means of a switch (14LS), Fig. 5 (not shown), which is actuated by a lever 323, Fig. 2; the table can be lowered for replenishing purposes under the control of further switches (4LS, 15LS) Figs. 1 and 5 (not shown). The sensor 500, Figs. 2 and 3, is carried on a cross-bar 327 pivoted on stub shafts 324, and having fixed thereto the actuating lever 323. A floating guide bar 401 behind crossbar 327 helps to constrain the topmost sheet of the stack 305 during sheet separation. Two brackets 501 are secured to the cross-bar 327 and together with a contact member 510 form a U-shaped portion, which is oscillated into contact with the topmost sheet between individual sheet-separating operations by means of a cam (not shown) rotating with the main sheet-feeding drive and a cam follower mounted on the end of lever 323 remote from pivot 324. The contact member 510 has a paddle-wheel cross-section with vanes 512 of varying lengths: the orientation of the wheel can be selected by rotation of shaft 511 under the action of knob 513, the selection being determined by the thickness of the sheets being separated. In the particular embodiment described, the choice of vane will determine the amount of aeriform fluid entering between the top sheet and the sheet beneath. Further sheet guide members 517 are pivoted at 518 on the brackets 501, a shoulder 516 on a vane 512 engaging the upper arms of the guides so that the bottom portion of the guides rest on the stack. Reference has been directed by the Comptroller to Specification 1,122,627.
