Filed: 1964-01-28
Abstract: 1,013,206. Articulators. C. E. STUART. Jan. 28,1964, No. 3545/64. Heading A5R. A face bow for establishing the relationship between the orbital plane and the occlusal plane is associated with an articulator, to which it can be attached to serve as a guide for correct adjustment. The face bow comprises two arms 11, Fig. 2, pivoted at 20 to a cross bar 12 and locked in position by a clamping screw 14. At their rear ends these arms carry spherical tips 13 for engagement with the tragi of the patients ears, see Fig. 1 while the cross bar carries a member 15 for engaging the nasion N. A bite plate 19 is carried on a rod 29 adjustably attached by a clamp 18 to a further rod 25 secured to the cross bar 12 and, in use, the tips 13, bite plate 19 and guide 15 are adjusted and clamped in position. It is known that the condyle pivots C are approximately a quarter of an inch in front of the points of contact of the tips 13 and a round-headed screw 17 is provided which will be tangential to the orbital plane. These facts are made use of in setting up the face bow on the articulator to which it is attached by engaging the tips 13 with blocks 39, Fig. 3 not shown, which are pivoted to the base on pillars 39 mounted on an upright support 44. The post 25 rests on a block 35, on the base 41, and the mounting plate 36 is lowered to rest on the head 27 of the screw 17 so that it is then known to lie in the orbital plate P. Plaster 62 may then be filled in between the adjustable carrier 60 and the model 37, the latter having been previously positioned accurately on the bite plate 19.

Filed: 1970-01-26
Abstract: 1,263,899. Feeding and transferring cans on endless conveyers. FMC CORP. 26 Jan., 1970 [30 Jan., 1969], No. 3604/70. Heading B8A. A row of cans C on a feed conveyer 70 is pushed by a mechanism 80 (Fig. 3) into carriers 46 of a cooking chamber conveyer 44, a row of processed cans being pushed by a member 152 on to a discharge conveyer 74. The conveyer 70 has a guide 102 (Fig. 7) immediately above the tops of the cans so as to prevent chimes 42 of the cans overriding each other. Further feed of cans on the feed conveyer 70 is prevented by the action of rails 86, on either side of a short length of the conveyer upstream of the row of cans to be fed, which lift six consecutive cans so that their top surfaces engage a brake pad 84. This operation takes place in synchronism with the movement of the cooker conveyer 46, a drive-shaft 62 of which carries cam sections 124 (Fig. 4) which operate a valve 132. The latter is connected to a valve V<SP>1</SP> (Fig. 7) and this energizes an operating cylinder 94. A valve 128 is also operated by the cam sections 124 to energize (via valve V) an operating cylinder 120 which operates the feed pusher mechanism 80. This comprises a pusher 106 and a guide-bar 108. The latter guides the containers during their transit on the feed conveyer 70. The discharge pusher 152 is operated by a cam 180 geared to the drive-shaft 62 and actually passes in between adjacent lateral rows of the carriers 46. While still projecting between the rows it moves upwardly with the conveyer 44 as it is withdrawn. The cans need not have chimes 42, need not be of circular cross-section, and may be conveyed on their sides instead of on their bases.

IPC: H01B1/00
Filed: 1967-01-26
Abstract: 1,170,521. Printed circuits. WESTERN ELECTRIC CO. Inc. 26 Jan., 1967 [1 Feb., 1966], No. 3937/67. Addition to 1,125,394. Heading H1R.  A thin film circuit is made by the selective sequential etching of a laminate 20, Fig. 3, comprising a substrate 21 of glass or ceramics, a resistive layer 22 of tantalum nitride or niobium nitride, a protective layer 23 of Sb, Bi, Mo, W or Zr, and an electrode layer 24 of Ta or Cb; the protective layer 23 protects the resistive layer 22 during the etching of the electrode layer 24. Layers 22-24 are deposited by sputtering or vacuum deposition, preferably in a continuous process. In one embodiment, Fig. 5, a first resist 26, is applied by silkscreening or photographically, to a Ta electrode layer 24 in the pattern of a desired conductorcapacitor circuit, and the exposed areas of layer 24 are etched with an etchant such as hot NaOH which does not react with the Sb layer 23. Resist 26 is removed, and the exposed areas of Sb layer 23 are removed by etching as with H 2 SO 4  or aqua regia, which do not attack layers 22, 24. A second resist 27, Fig. 9, is now applied to the conductor-capacitor pattern and also to the areas of layer 22 required for resistor formation, and exposed areas of layer 22 are removed, as with NaOH; alternatively, a mixture of HF and HNO 3 may be used, in which case the formation of an oxide layer between substrate 21 and layer 22 is desirable to prevent undercutting, as disclosed in Specification 962,015. Resist 27 is now removed. The values of the resistors are trimmed by anodization, and the Ta layer 24 is anodized to form a dielectric layer 28, Fig. 11, for capacitors, which are completed by the vapour deposition of Au top electrodes 29. Finally, terminals 30 and conductive paths 31 are deposited, being made of Au, or successive layers of Ni-Cr alloy, Cu and Pd. In a modification, a conductive layer for terminals 30 is deposited above layer 24 before the first etching step. In another modification, layers 22, 23 are etched together by a mixture of HF and HNO 3 in a single step. The invention is described with reference to the production of a frequency rejection filter circuit (Fig. 12, not shown); this comprises an inductor which may be formed by thin-film technique or may be a conventional inductor connected to the thin-film circuit. The Specification contains a table of etchants suitable for use when protective layer 23 is formed of Bi, Mo, W or Zr.

Abstract: 552,658. Frequency modulation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 26, 1942, No. 4019. Convention date, March 26, 1941. [Class 40 (v)] Receivers for frequency-modulated waves include two heterodyne stages by which the mean incoming frequency is reduced to a frequency greater than but comparable with the frequency deviation of the incoming wave, the two stages being fed from the same local oscillator. The detector may be of the counter type. The twostage production in frequency is effected by mixer stages 5, 51 fed with oscillations from the local source 12. The input circuit 2, local oscillator circuit 13, and inter-stage circuit 21 are tuned over a given range by ganged control 22; while the final output circuit 21 is fixed tuned to a frequency say 0.2 mc. of the same order as the frequency deviation of the incoming wave, The output wave is fed through an amplifier 30 to a linuter stage 31 which provides AVC voltage for the mixer valves. The limited output is passed to a screen-grid amplifier 61 with its plate resistance 62 connected through a condenser 63 to an earthed resistance 64. A diode 65 is shunted across the resistance 64, and a second diode 66 has its anode connected through a resistance 67 to the anode of diode 65, and through a resistance 71 to the audio-frequency amplifier. With this arrangement, the average current through the resistance 64 is proportional to the input frequency; and the voltage passed to the AF amplifier varies with the frequency deviation. Interference from " image " frequencies may be prevented by interposing rejector circuits 11 between the aerial 1 and the input transformer.
