Title: Method and apparatus for forming glass
IPC: C03B19/04
Filed: 1961-06-02
Abstract: The circumferential relationship between a centrifuging mould for glass ware with an independently driven forming tool arranged thereover is maintained by driving the forming tool through a torque amplifier and regulating the coupling therebetween by a synchro receiver which is driven by coupling it to a synchro transmitter driven in synchronism with the mould.  A rectangular funnel-shaped mould 11 for forming the funnel of a cathode-ray tube is supported on a shaft 20 and rotated by shaft 12 through gears 13, 14 to centrifuge the charge 26 of glass.  A distributer 17, with pointed end for forming the neck of the tube, has four bosses 18 to form grooves in the tube at the junction of the funnel and the neck.  The shaft of a synchro-transmitter 21 has gear 16 meshing with gear 15 on shaft 20 of mould 11 and is electrically coupled by a cable 22 to a synchro receiver 23 associated with a torque amplifier 30 connected to alternating current at A.C.  The <PICT:0968352/C1/1> <PICT:0968352/C1/2> shaft 24 of receiver 23 carries a drive pinion 25 in mesh with drive gears 31, 32 of amplifier 30 which are connected through bands 33, 34 helically wound on drums 39, 40 to drive gears 35, 36, which in turn mesh with pinion 60 on shaft 41 of distributer 17.  Gears 31, 32, 35 and 36 are free to rotate about the shafts 37, 38 carrying the drums 39, 40.  Shaft 37 and drum 39 are driven directly from motor 50 and shaft 38 and drum 40 are driven by meshing gears 43, 44. The distributer 17 is therefore normally driven through motor 50 and torque is only transmitted to band 33 or 34 when the position of rotation of the transmitter 21 deviates from that of receiver 23 so that frictional coupling of band 33 or 34 corrects the deviation.  Specifications 674,565 and 703,386 are referred to.

Abstract: 498,146. Optical sound - recording. SCOPHONY, Ltd., and WIKKENHAUSER, G. July 20, 1937, No. 20057. [Class 40 (ii)] [Also in Group XL] In an arrangement in which a double sided sound record is produced on a film F by light from a source S modulated by being passed through an optical system including a cell A through which sound-modulated high-frequency waves are passed, the crests of the recorded waves are brought always near the outer edges of the record strip to reduce noise-level at low sound amplitudes by increasing the mean highfrequency output of the oscillator when the sound amplitude decreases, this control being obtained by rectified current derived from rectification of the sound oscillations.

Abstract: 1471732 Glass fibre manufacture OWENS-CORNING FIBERGLAS CORP 7 May 1974 20068/74 Heading C1M [Also in Division G3] A production line for the manufacture of fibrous structures is controlled by a plurality of control loops responsive to set point data derived by a variable scan-rate data-processing apparatus, see Divisions G2-G3. As shown, glass is supplied by a forehearth 10 to an electrically heated feeder 11 having orifices 12 for a molten stream of glass from which fibres are produced by a blower 13. The fibres are deposited on a predetermined area of a conveyer belt 41 by control of the side-walls of a hood 30. A binding agent is added through a dispenser 50. The quantity of fibre per unit area is determined by an X-ray sensing device 60 to provide (a) corrective signals for a line speed control 45, (b) a binder feed control 53 the blower 13 and (c) back-up for a throughput sensing device 25 to modify the effect of a bushing power control 20. The fibre mat is compressed by a roller device 65 under control of a sensing unit 66. The compressed mat passes through an oven 70 for curing the binder. The oven incorporates air ducts 71, 72 and a heater 74. The width of the mat is then trimmed by a saw 80. An alternative fibre providing apparatus Fig. 3, not shown, builds up a mat of continuous strands containing a plurality of filaments.

[Class 137.] A conduit for the distribution of humidified air is constructed by superimposing standardized gutter shaped elements of similar shape in such a manner as to form a conduit having longitudinal slits to serve for the distribution of the air. A number of similar tapering gutter elements such as those numbered 1 to 14 in Fig. 1 are assembled end to end to form the lower wall 1 of the conduit, Fig. 7, and smaller similar elements such as those numbered 5 to 18 to form the upper wall 2. The elements are suspended by means of brackets 5, a longitudinal space 3 being left between the upper and lower walls for the distribution of air. Air is forced into the conduit by means of a jet of water or other liquid such as disinfectant which also serves to humidify the air. An additional oppositely disposed jet may be used when it is required to withdraw foul air. In a modification, an additional lower wall is suspended beneath the wall 1, forming another conduit which may be used for the distribution of air otherwise treated, for instance, heated air in winter.

Title: Decoding apparatus
IPC: B61L3/24
Filed: 1971-04-19
Abstract: 1328445 Frequency detectors GENERAL SIGNAL CORP 19 April 1971 [27 Jan 1970] 20489/71 Heading H3A [Also in Divisions B7 and G4] Decoding apparatus uses high and low pass rate thresholding to recognize each of a plurality of signal repetition rates. Receiver coils 10 on a railway vehicle pick up, from a track circuit, an A.C. carrier modulated at one of 3 frequencies. The carrier is eliminated at 12 and for each transition of the resulting square wave a negative pulse is produced at e and a positive pulse at d. In low-pass rate filter 15-H, with transistor 30 normally off, capacitor 34 charges via resistor 35 and diode 39 and discharges concurrently but more slowly via resistor 37, so that the capacitor reaches a threshold at which transistor 31 conducts to discharge capacitor 34 completely via 31 and produce an output pulse at f. An input pulse at d makes transistor 30 conduct to prevent charging of capacitor 34 during the duration of the pulse, so if pulses at d occur too frequently, pulses will not be produced at f. In high-pass rate filter 16-H, an input pulse at e cuts off transistor 41 so that capacitor 44 can charge via resistor 42 and diode 45 during the duration of the pulse. It also discharges via a parallel resistor. If the pulses at e occur frequently enough, the capacitor voltage will reach a threshold which turns transistor 46 on, discharging the capacitor completely via 46 and producing an output pulse at g. So if the pulse frequency at d, e is high enough to "pass" 16-H and low enough to "pass" 15-H, a flip-flop 17-H is switched on and off alternately by the pulses at f, g and a relay driver 18-H responsive only to alternating current actuates a relay 19-H. Similar arrangements are shown controlling relays 19-M, 19-L, 19-A. Relays 19-H, 19-M, 19-L are thus actuated in response to the 3 frequencies respectively, and relay 19-A is actuated in response to any frequency lying in a range embracing all 3. If relay 19-A is actuated, a speed governor of the vehicle receives a signal specifying 15, 35 or 65 mph according to which of 19-L, 19-M, 19-H is actuated, but if 19-A is not actuated 3 mph (effectively "stop") is commanded. An under-speed relay associated with the governor is also controlled by a contact network of relays 19-L, 19-M, 19-H which checks that one and only one is actuated, the under-speed relay controlling a brake relay and an audible or visible alarm. The output of the decoding apparatus may go to indicator lights instead of to a speed governor.
