Title: Improvements in or relating to the hydrogenation of naphthalene
IPC: C07C7/148
Filed: 1920-07-08
Abstract: Naphthalene to be hydrogenated by the process described in the parent Specification is preliminarily purified by treating in the fused state with finely divided metals such as nickel or iron, or with readily fusible metals, such as sodium or potassium, either alone or admixed with fullers' earth or similar porous materials; the metals selected must have an affinity for sulphur &c.  The materials are stirred together in an atmosphere of hydrogen under pressure and maintained at a temperature of above 100 DEG  C., and the purified napthalene is preferably distilled off under reduced pressure.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of metal alloys.  This subject-matter does not appear in the Specification as accepted.ALSO:Naphthalene to be hydrogenated is preliminarily purified by treating in the fused state with finely divided metals such as nickel or iron, or with readily fusible metals such as sodium or potassium, either alone or admixed with fuller's earth and similar porous materials; the metal selected must have an affinity for sulphur &c.

Title: Artificial reverberation control apparatus
IPC: G10K15/10
Filed: 1960-06-03
Abstract: 912,720. Electrical musical instruments. HAMMOND ORGAN CO. June 3, 1960 [June 4, 1959; July 21, 1959], No. 19696/60. Class 88 (2). [Also in Group XXXIX] Audio-frequency electrical signals from an electrical musical instrument are applied to two channels, one of which includes a reverberation device. In one arrangement, Fig. 2, signals from an electric organ 10 are applied through a compensating network 16 to a capacitor-type volume control 18, 20, 22, the electrode 22 of which is connected to an amplifier 28 and loud-speaker 30. A part of the output of amplifier 28 is applied successively to a variable attenuator 34, a reverberation device 42, an amplifier 46 and a loud-speaker 48. The variable attenuator 34 has a variable contactor 40 mechanically coupled to electrode 22 of the capacitor-type volume control and both are simultaneously operable by a control device, e.g. the expression pedal of the electric organ. If the control device is operated to increase the amplitude of signals applied to amplifier 28 the contactor 40 makes contact successively with junctions between resistors R36 in such manner that the amplitude of the signals applied to the loud-speaker 48 increases by a less amount than the amplitude of the signals applied to the loud-speaker 30. In a second arrangement, Fig. 3, audio-frequency electrical signals from an electrical musical instrument 100 are applied to a loud-speaker 160 and, through a filament lamp 180, successively to a reverberation device 300, an amplifier 240 and a loud-speaker 260. The resistance of the filament of lamp 180 increases as the amplitude of the signals applied to it increases such that, as the amplitude of the signals at loud-speaker 160 increases, the amplitude of the signals at loud-speaker 260 also increases but by a less amount.

Filed: 1924-08-20
Abstract: 224,503. Bemberg Akt.-Ges., J. P. Nov. 5, 1923, [Convention date]. Apparatus for making filaments.-In the spinning of artificial silk from cuprammonia cellulose solutions by the stretchspinning method, the filaments are fi r s t treated with a countercurrent of the coagulating-liquid until sufliciently set, and are then subjected to a current of liquid moving in the same direction as the filaments. For this purpose the coagulating-liquid is introduced through a connection a at the lower part of the funnel c, at which point the stream of liquid divides into a slowly-moving upward current and a rapid downward current, that is a current in the direction of travel of the filaments. The liquid passing up the funnel c, Fig. 1, flows over the edge and escapes through a controlled outlet s; by this arrangement there is a quiescent column of liquid immediately below the spinning-nozzle b; alternatively, the liquid may be allowed to escape at an outlet. d at the upper part of the enclosing cylinder e, Fig. 1, and in this case the outer vessel e may be dispersed with, the funnel c being continued as a cylindrical upper portion f as shown in Fig. 2.

Abstract: 1,245,045. Electric selective signalling. J. PONS. 17 April, 1969, No. 19783/69. Heading G4H. A shaft is rotated by a reversible motor 16 (Fig. 1) by an amount dependent on the number stored in, for example, a binary coded decimal counter 4. The counter may be read out at regular time intervals so that the shaft displacement represents the mean frequency of the pulses at input terminal 2 during each time interval. In the embodiment of Fig. 1 the contents of the counter are fed to a store 6 connected to a decoder 11 delivering a signal on one of ten leads E 0 -E 9  to a diode matrix 13 which, for an input signal on lead Ek delivers a "1" output on leads S o -S k  and a "0" output on leads S k+1 -S 9 . The leads S 0 -S 9  are connected to NAND gates 21 the gates deriving their other input from contact studs 18 of a switch 17, the studs being enabled in pairs. The switch 17 is rotated by motor 16 either forwards or backwards in dependence on whether 0 or 2 of the gates 21 have "0" outputs until only one of the gates 21 has a "0" output when the rotation of the motor-driven shaft from a datum represents the count. An indicator needle may be carried by the shaft. The apparatus may be modified (Fig. 2, not shown) for multi-decade counters, each decade controlling a diode matrix and gates, the motor being responsive to the outputs of the gates of the decades in order of decreasing significance.

Title: Monitor and Delay Network
IPC: H03M1/36
Filed: 1967-05-01
Abstract: 1,176,347. Protective systems. BENDIX CORP. 1 May, 1967 [6 May, 1966], No. 20027/67 Heading H2K. [Also in Division H3] A circuit for detecting when a signal exceeds a predetermined level comprises means for feeding the signal (A.C., pulsating D.C. or periodically separated aperiodic A.C. such as a ramp function) together with a reference level voltage to a positive-feedback amplifier whose output thus consists of pulses at the input frequency and of width proportional to the amount by which the input signal exceeds the reference level, clamping the amplifier output in one polarity and passing the other polarity output to a hold circuit and thence to a threshold detector and alarm device, so that appearance of pulses at the amplifier output causes the alarm to function after a predetermined delay. The circuit may be designed to detect either positive or negative excessive excursions of the input signal. In Fig. 5 the input signal E s  is combined with a reference level V R  in summing resistors 37, 39 and the resultant applied to an operational amplifier 45 which has positive feedback through resistor 59 to produce a two-level output whose lower level is clamped to ground by diode 50. The amplifier output will be at ground potential if the input signal is less than the reference level, but otherwise will consist of pulses at the frequency of the input signal and having a width proportional to the amount by which the input signal exceeds the reference level. These pulses charge capacitor 73 rapidly through diode 61 and maintain the capacitor voltage and a level sufficient to prevent conduction in transistor 85. The pulses also charge capacitor 87 through resistor 89, the output voltage at 54 rising slowly to a steady value. When the pulses cease, capacitor 73 discharges through resistor 71, transistor 85 conducts, capacitor 87 is discharged and the voltage at 54 rapidly falls to ground level. While the pulses are present, the voltage at 54 causes Zener diode 105 to conduct, and the Darlington pair 115 139 conduct to energize an alarm 57. A number of such circuits may be connected in parallel with different reference levels to form an analogueto-digital converter (Fig. 4, not shown). If it is desired to sample the input voltage at predetermined instants a clock pulse source 325 periodically operates transistor 302 to make or break a short circuit across the input. Modifications.-The threshold detector may comprise a field-effect transistor (Fig. 6, not shown) with a Zener diode in its source lead. This is followed by a single transistor as the high impedance of a Darlington connection is not now necessary. An extra transistor stage may follow the Darlington stage (Fig. 7, not shown), operating a relay with normally closed contacts to provide a fail-safe arrangement, the alarm being operated if the circuit or its power supplies fail. The reference voltage 35 may be in series with the diode 50 and ground (Figs. 6 and 7, not shown) and may include a Zener diode voltage dropper.
