Filed: 1948-08-09
Abstract: 674,045. Code telegraphy. PHILIPS ELECTRICAL, Ltd. Aug. 9, 1948 [Aug. 12, 1947], No. 20929/48. Class 40 (iii). [Also in Group XL (c)] In a telegraphic device for sending and receiving signals in which one or more stages embodying electric discharge tubes act as amplifiers when the device is conditioned for reception and as a monitoring audio-frequency oscillation generator when the device is transmitting, a source of anode voltage is connected through a send-receive switch to the said stages continuously during reception and intermittently in accordance with the telegraph signals during transmission through an audiofrequency impedance so arranged that voltage variations developed across the said impedance are fed back to an input terminal in the said receiver, the magnitudes of the circuit components and the phase of the feed-back being such that audio-frequency oscillations are generated in the receiver. In one arrangement, Fig. 1, received signals after passing through high frequency, intermediate frequency and detector stages 2, 3 are fed as audio-frequency signals to valves 4, 5, 6 controlling a reproducer 7, the send-receive switch 12 being in the lefthand position and applying anode voltage to the valves from a battery 11. In the sending condition the switch 12 is moved to the right-hand position so that when the transmitter 9 is keyed at 8 voltage is fed via the impedance 13, anode load 14 of valve 4 and condenser 15 to the grid of valve 5 which in conjunction with the valve 6 and the common feed-back impedance 13 oscillates at a predetermined frequency to produce in the reproducer 7 signals corresponding to those transmitted. In a modification, Fig. 2a, the voltage from the impedance 13 is fed via a condenser 20 to a tapping-point on the input grid resistance 19 of the valve 17. In another modification, Fig. 2b (not shown), the feed-back voltage is applied via a condenser to the junction of the grid input and grid resistance of the valve corresponding to the valve 17 of Fig. 2a. In further modifications, Figs. 3a, 3b (not shown), in which the oscillation generator employs a single valve, the voltage from the feed-back impedance is reversed in phase before application to the grid of the valve. The phase-shifting network comprises an autotransformer with a tapping-point to earth and one of its ends connected to the grid of the valve. Alternatively an arrangement of resistances and condensers may be employed to effect phase reversal.

Filed: 1974-05-15
Abstract: 1454606 Interferometers INTERNATIONAL BUSINESS MACHINES CORP 15 May 1974 [29 June 1973] 21505/74 Heading G2J An interferometer comprises means for projecting electromagnetic radiation of a given wavelength along a given path, a collimator element and a further radiation directing element disposed in the given path, the collimator element being at least partially spherical and having an index of refraction such that a parallel beam of incident radiation is focused on its rear surface, the collimator element also producing a parallel beam of radiation between said elements from a non- parallel input beam of radiation projected by said means. In the form shown Fig. 1 the interferometer comprises two glass spheres 4, 6 both of which have surfaces 10, 8 which are partially reflecting. Source 2 is a HeNe laser emitting at 6328 Š and the glass of the spheres is chosen to have an R.I. of approximately two at this wavelength. In a modification Fig. 2 (not-shown) sphere 6 acts purely as a retro-reflector, there being a plane beam-splitter (11) between the source and sphere 4 which directs the interfering beams to the fringe detector and counter the output of which generates a signal which causes movement of sphere 6 e.g. to a required position. A comparator may be used to indicate zero difference between desired and actual fringe counts. The absolute distance between the spheres may also be measured by knowing the radii of the spheres and setting the fringe counter to zero when they are touching. In Fig. 3B six actuators 22 are controlled by interferometers formed by spheres 23, 24 on a movable body 20 and a fixed body 21 respectively. The six distances may be compared, using a computer, with desired values and signals given to the actuators to move the body 20 in any desired way except continuous rotation. The latter may be achieved using a crank-shaft like arrangement Fig. 4 (not shown). The actuator may be a hydraulic ram Fig. 5, (not shown) having an annular piston and cylinder allowing the hollow central longitudinal bore to form the light path between a glass sphere at each pivotal connection of the ram to the fixed and movable body respectively. The ram is capable of low frequency changes in length; a Piezo-electric or magneto-strictive transducer may be added to the ram for higher frequency operation Figs. 6A, 6B (not shown). Alternatively the pivotal bearings may be hydrostatic with differential pressures at opposite bearing pads Fig. 6C (not shown). An interferometrically positioned spindle is also described Fig. 7A (not shown). For the measurement of objects Fig. 8 e.g. for length, radius and position three point-to-point interferometers formed by movable sphere 101 and each of spheres 100A, 100C and 100D are used. The movable sphere is placed by hand against the workpiece 103 and the computer calculates and stores its position. By repeating this process, enough information is built up to characterize the position and dimensions of the workpiece 103. A redundant interferometer may be formed by spheres 101 and 100B e.g. for internal checking.

In making a composite metal plate, tube, &c., from mild-steel or low-alloy steel and stainless steel, one metal 1 in solid form with its surface cleaned, as by machining, shotblasting, grinding, pickling, &c., is put in a vacuum vessel 4, and another metal is cast completely around metal 1 while the vessel is maintained under substantial vacuum, the composite article thus formed being hotrolled to weld the two metals together. As shown, a mild-steel or low-alloy steel plate 1 is located in a mould 3 by pieces 2. A ladle 9 for stainless steel to be cast on to the plate 1 has a base-flange 18 which contacts a sealing ring 17 on a ring 8 surrounding the pouring opening in the vessel 4. Connections 12, 13 from the vessel and the space beneath the ladle are taken to a vacuum pump. When a stopper 11 in the ladle is raised the molten metal falls on to an aluminium plug 7 in the vessel, melting the plug and falling into the mould. After solidification, air-cooling may take place, followed by heating and hot-rolling. In a modification, in which melting and casting are effected in a vacuum, Fig. 2, the vacuum vessel 19 houses an electric furnace 20 which turns on pivots 21 during pouring. Two stainless steel plates 15 separated by several layers of stopweld paint, consisting of chromic anhydride, green chromic oxide and water, and welded together at their edges, are located in the mould 23. Mild steel or low-alloy steel is cast around the plates, and after rolling and edge-trimming the plates are separated, providing articles clad on only one side. As applied to making a tube, a hollow ingot of mild steel having a stainless steel coating on the inner and outer surfaces is produced which is then rolled and drawn.

[Also in Divisions B2 and B4] A process for the recovery of the textile content and the production of rubber grist from rubber articles containing textiles-especially motor tyres -comprises slicing and then milling the articles followed on the one hand by processing the cord fibres obtained and on the other hand by sieving the rubber grist to sort it and remove textile remnants. Rubber tyres are put on rotating tables 1 and are sliced into rings, Figs. 2-4 (not shown), which are cut into slabs and fed into a slicing machine 2 (see Division B4). The slices thus obtained are passed into a milling machine 3 of known construction, for example a Condux type. Cord fibres pass from the mill 3 to a licker-in 14 having feeding rollers 60 (Fig. 8) of small diameter because of the short fibre length and then to a willowing drum 61, a suction cylinder 62 and vibrating machine 65. The material then passes through a three stage carding willow 16-each stage having a willowing drum 69 and suction drum 70- a "continuous batcher" 74, and a carding machine 19 and finally reaches a lap winder 20. Vibrating sieves and an air stream 53, Fig. 7 (not shown), remove textile remnants from the rubber grist and sort the grist by grain size.
