Title: Improvements in electromagnetic "make", "break" and resetting mechanism
IPC: G08B13/00
Filed: 1923-05-22
Abstract: 222,169. Waddington, A. S. May 22, 1923. Inertia switches; switches, partly electromagnetic; actuating. - In switches applicable to theft alarms for motor cars &c. of the kind in which a circuit is closed by vibration of one of the contact-members, the circuit of an electric motor is closed thereby and means are provided for automatically stopping the motor after a given time, during which an alarm is given. In the form shown in Fig. 1 a casing 1 contains a motor 2, the shaft 3 of which carries a disc 4. On this disc are arranged weights 6 which during rotation of the shaft 3 engage a projection 10 within a bell-gong 9. The circuit of the motor is completed by vibration of a spring blade 16 anchored at one end, which causes a contact 19 to engage a fixed contact 20. The spring 16 carries an armature 15 which is magneticaly held against the motor field poles. To limit the period of operation of the motor an eccentric drum 11 is mounted looselv on the shaft 3 and carries a weight 12 to retain it in the position shown in Fig. 5. When the speed of the motor has increased sufficiently arms 13 pivoted at 5 on the disc 4 fly out centrifugally against the action of springs 14 engaging the drum 11 which is carried round, its eccentric outer periphery forcing upwards the adjustable screw 23 on the spring blade 16 and so breaking the motor circuit at contacts 19, 20. The weight 12 subsequently restores the drum 11 to its former position, enabling a, further alarm to be given on vibration of the casing 1. The motor circuit may, alternatively be completed by a separate switch (Fig. 7) consisting of a metal tube. 25 in which is suspended a weight 29 attached to a chain 28. Vibration of this switch brings together the tube 25 and weight 29 so completing the circuit of the motor 2 and signal lamp 30 which may be arranged to shine on the person operating the alarm, as shown in Fig. 9. Alternative means for resetting the alarm are described in a further modification, which consists of a spring-pressed lever co-operating with a heart-shaped cam on a wheel geared to the motor shaft, energy stored in the spring during rotation of the motor, being effective to restore the mechanism to its initial position.

Title: Improvements in paper and like containers for tobacco and other products
IPC: B65D65/40
Filed: 1939-05-08
Abstract: 528,472. Paper and like containers. MOORE, G. A. May 8, 1939, No. 13702. [Class 94 (ii)] A container suitable for tobacco, is formed from a single laminated blank made up of one or more inner layers of fibrous material, e.g. paper, and one or more outer layers of non- hygroscopic sheet, e.g. aluminium foil, the marginal portions of the ends of the blank being infolded to form a foil-lined reinforced hem 24, Fig 3. After folding, the container is closed at each end by pressing opposing sides of the hem 'together, Fig. 4, and sealing the hem under heat treatment by an interposed thermoplastic adhesive to form a metal-to-metal closure seam. Each hem and its projections are then folded flush with the top and sides of the container and sealed in position. The arrangement ensures that no raw edges of the fibrous material of the container are exposed to the atmosphere when the seams are sealed. The edges of one hem may be left unsealed to constitute a tab whereby the sealed surfaces may be pulled apart when it is desired to open the container. The containers may be strengthened by internal liners.

Title: Process for the separation of a mixture containing hydrocarbons
IPC: C10G21/28
Filed: 1965-03-29
Abstract: In a process for separating a hydrocarbon mixture by means of liquid-liquid extraction by a selective solvent boiling higher than the mixture, a raffinate and an extract phase being obtained, the extract phase being separated into solvent and an extract, and solvent being recovered from the raffinate and/or the extract by washing at least one of these by means of an aqueous washing medium, the used washing medium is then treated for recovery of solvent therefrom by contacting it with a hydrocarbon-containing mixture, e.g. the incoming feed hydrocarbon mixture.  Additional solvent may be recovered from the contacted used washing medium by distillation, and the finally treated aqueous washing medium may be recycled. Suitable solvents are of the sulpholane or glycol type, examples being given, and the process is particularly suitable for recovering aromatics from kerosene or catalytic reformates.  In the illustrated embodiment, feed hydrocarbon 1 is used to wash a water/sulpholane mixture 7 <PICT:1082188/C4-C5/1> in column 3, the solvent-freed water leaving at 5, and the hydrocarbon/sulpholane mixture 8 then being countercurrently contacted in column 9 with sulpholane 11.  The extract 15 is then stripped in column 17 to give a non-aromatic extract which is returned to column 9, and an aromatic extract 21 which is passed to column 23 where sulpholane is separated and recycled to column 9.  The raffinate 13 from column 9 and the aromatics 25 from column 23 are separately washed for removal of solvent by water 28 and 33 in columns 27 and 32, respectively, the used water now containing sulpholane being combined as stream 7 which is passed to unit 3 for contact with incoming feed.  The washed raffinate and aromatics are recovered as 29 and 35 respectively.

Title: Liquid level supervisory apparatus
IPC: G01F23/26
Filed: 1960-04-21
Abstract: 892,957. Transistor relay circuits. AMERICAN DISTRICT TELEGRAPH CO. April 21, 1960 [July 21, 1959], No. 13981/60. Class 40(6). [Also in Group XXXVI]  In a liquid level detector (see Group XXXVI) comprising a capacitance bridge connected in the feedback path of a transistor amplifier, the bridge circuit comprises inductive ratio arms 14, 15 a reference capacitor 13 and a concentric measuring capacitor 10 immersed in a water tank. The capacitor 10 is connected via blocking capacitors 17, 18. The output diagonal is coupled to the base/emitter electrodes of transistor 20, the output of which is fed back to the ratio arms 14, 15 by winding 22. As the water level approaches electrode 10 the bridge becomes balanced and the feedback changes from degenerative to regenerative, initiating oscillation in transistor 20. The start of oscillation causes diode 19 to conduct, short circuiting the measuring capacitor 10 and increasing the unbalance of the bridge so that the circuit rapidly reaches a state of limiting oscillation. The circuit is therefore described as bi-stable, being either non-oscillating or oscillating with saturation current flowing. When the water level is below electrode 10, coil 23 is de-energized so that a clockwork mechanism 26 is able to generate a coded alarm signal. The system may be tested by closing switch 33, bringing diodes 34, 35 into conduction and connecting capacitor 36 across the reference capacitor 13. This has the same effect as low water level.

Abstract: 724,487. Multiplex radio signalling. HAZELTINE CORPORATION. May 20, 1953 [June 14, 1952], No. 14183/53. Class 40 (5). In a television receiver the output from the detector 15 comprises the picture signal, which is amplified in stage 16 and fed to the reproducer through terminals 40, and a 4.5 Mc/s. carrier, frequency-modulated by the sound signal and produced by the interaction in the detector 15 of the sound and vision I.F. carriers whose difference frequency is 4.5 Mc/s. The sound carrier is derived from the stage 16 and fed through a limiting amplifier 18 to the frequency demodulator 19, the derived audio signals being fed to the reproducer through terminals 66. According to the invention, the stage 16 contains a valve 31, the cathode impedance of which comprises a circuit 42 resonant to the sound carrier and producing negative feedback at this frequency, while the sound carrier is fed to stage 18 from the same resonant circuit. In order to establish the correct impedance relationships, the cathode of valve 31 is tapped down at point 67 on the inductance 68 of the circuit 42, the impedance at this point, however, being greater than the reciprocal of the transconductance of the valve.
