Abstract: 1,072,066. Welding by pressure. AEROPROJECTS Inc. June 29, 1964 [July 3, 1963], No. 26857/64. Heading B3R. [Also in Division H4] In vibratory welding apparatus, Fig. 4 (not shown), such as described in Specification 837,869, the electro-mechanical transducer assembly 10 (Fig. 1) includes an even number of ceramic elements 12, 14 dimensioned and arranged to operate at a given frequency, each adjacent pair being separated by a spacer 22. The elements 12, 14 are compressed between the parallel end faces of a coupling member 16 and a stabilizing member 18. The members 16, 18 are biased towards one another by a sleeve 20 resonant at the given frequency. The elements 12, 14 are under compression, left- and right-hand screw threads 68, 72 ensuring that rotation of sleeve 20 in one direction draws members 16, 18 together. Elements 12, 14 are of barium titanate or lead zirconate titanate and are of washer form. A 15 kc/s. signal is supplied through conductors 32, 34. Conductor 32 is connected to spacer 22 and conductor 34 establishes electrical contact through member 18, sleeve 20 and member 16 with the outwardly facing flat faces of elements 12, 14. An insulation sleeve 58 of " Teflon " (Trade Mark) prevents arcing. Inwardly directed ribs 60 of sleeve 58 hold the spacer 22 central. Members 16, 18, sleeve 20 and spacer 22 are of beryllium-copper or " K-Monel " (" Monel" is a Trade Mark) or nickel-aluminiumbrass. The overall length of assembly 10 is a whole number multiple of half a wavelength in the members 16 and 18. Members 16 and 18 are preferably ¥ of a wavelength long while sleeve 20 is a half-wavelength long or a wavelength long. Cooling is provided by the thermal conductivity of members 16, 18 and by a coolant, e.g. transformer oil or compressed air. Preferably oil is introduced through a radial inlet 40 and travels along a passage 38 to an annular passage surrounding spacer 22. The coolant then passes through radial holes 42 in spacer 22 and into its core. The oil is discharged through a passage 44 to an outlet 46 from where it is cooled and recirculated. Member 16 may be a mechanical transformer, comprising a cylindrical portion one quarter wavelength long joined to a tapered portion one half wavelength long. The tapered portion (16<SP>1</SP>), Fig. 3 (not shown), may have a linear or exponential taper. The assembly may use four or six transducer elements. In the welding apparatus (Fig. 4) the assembly (10) is connected to a mechanical transformer (76) joined to a sonotrode (78) supported in a mass (80) actuated by an hydraulic system (not shown) to apply a clamping force to a weldment (82). Member 18 is supported from a cantilever (86) by a vertical link (88).

In a diversity radio communication system comprising at least two separable signal channels feeding the transmitter, intelligence signals are supplied to one of the channels and the same intelligence signals are supplied to one of the channels and the same intelligence signals are supplied to another channel after a predetermined time delay. At the receiver a similar delay is introduced in the previously undelayed channel whereby the signals on the two channels are brought into coincidence and means are provided for selecting the better signal or for combining both signals. With the switches SA, SB, SC and 11A, 11B in the position shown the signals from channel A, e.g. telephone signals, are fed via a filter 8 removing a narrow frequency band, e.g. 0-40 c/s., to a time delay device 7, e.g. a magnetic recording drum with spaced recording and pick-up heads, and the delayed signals modulate a sub-carrier at 5A and are then fed to the transmitter 1. The undelayed signals from A are also fed via switch SC to modulate a further sub-carrier at 5B, the signals from modulator 5B being fed to the transmitter 1. The output from the receiver 2 is fed to channel separators 9A, 9B, and detectors 10A, 10B, whose outputs are fed to respective contacts 12A, 12B of a selector device shown as a relay 12. The circuit to the contact 12B includes a delay device 13 providing the same delay as the device 7. The outputs of the detectors 10A, 10B are also supplied to respective 0-40 c/s. filters 14A, 14B, whose outputs are fed to a known comparator to switch the relay contacts to the channel providing the better signal at that time. With the switches SA, SB, SC and 11A, 11B in the alternative position the time delay devices are disconnected and the system provides two separate signalling channels A and B in conventional manner.

Title: Improvements in the conversion of various kinds of coal, tars, mineral oils and the like into fuels of low boiling point
IPC: C10G1/00
Filed: 1928-09-28
Abstract: 325,862. Johnson, J. Y., (I. G. Farbenindustrie Akt -Ges.). Sept. 28, 1928. Hydrogenation, destructive.-In the conversion of distillable carbonaceous materials such as coal into liquid fuels of low boiling point range by destructive hydrogenation in the presence of catalysts in more than one stage the choking of the catalyst by carbon compounds of high molecular weight is avoided by converting the said compounds into products of lower molecular weight or by removing them to a considerable extent from the vapour products of any stage without, however, condensing appreciable quantities of other substances suitable for further conversion. The removal of the high molecular compounds may be effected by condensation or by absorption with liquids or with porous bodies such as active carbon, silica and the like. If the said compounds are to be converted into others of lower molecular weight a catalyst particularly insensitive to clogging is employed. Pressures from 20 to 1000 atmospheres and temperatures from 300‹ C. to 700‹ C. are suitable. In an example, brown coal tar is treated with hydrogen at 420‹ C..and 200 atmospheres in the liquid phase. The product is passed as vapour at 420‹ C. over a molybdenum-zinc catalyst particularly insensitive to clogging and then at 460‹ C. over a catalyst of molybdenum and chromium trioxides. The product contains 80-90 per cent of benzines and is free from phenols. Active carbon may be used in place of the molybdenum-zinc catalyts. Specification 302,629 is referred to. Reference has been directed by the Comptroller to Specification 296,700.
