Title: Improvements in and relating to electrical recording instruments
IPC: G01R13/08
Filed: 1947-05-16
Abstract: 626,787. Recording-apparatus. DAVIS, N. R., and SUN-VIC CONTROLS, Ltd. May 16, 1947, No. 13276. [Class 106 (iv)] [Also in Group XXXVIII] Apparatus - for recording several variables comprises electrodes associated with an electrically-sensitive chart base, one of which electrodes forms a stylus electrically operated by the measuring element and switching means controlling the application of voltage to the stylus for modifying the voltage periodically in a synchronous relation with the commutation of the connection of the measuring element between circuits for the several variables so as to produce distinctive indications on the respective curves. A recording instrument 1 operates a stylus 2 co-operating with a chart 3 wound over a drum 4 driver at constant speed by an electric motor or clockwork 5 through a gear train 6, 7, 8. To record several variables such as voltage from three thermocouples, one side of each is connected through terminal 9 to one side of the instrument 1, while the other sides are connected through terminals 10, 11, 12 to fixed segments 13, 14, 15 of a commutator which has a moving brush 16 driven by the motor 5 and connected through a slip ring 18 and co-operating brush to the other side of the instrument 1. A source of voltage sufficient for recording is connected through a terminal 32 to the stylus 2 and through a terminal 31, slip ring and brush 30 and brush 19, driven with the brush 16, and thence through one of three contacts 20, 21 22 to an appropriate brush 23, 24, 25 and disc 26, 27, 28, through shaft 29, driven at a fraction of the speed of the brushes 16, 19, to the chart drum. The brush 19 co-operates with a contact when brush 16 nears the end of a segment, thus allowing the stylus 2 to settle before the recording circuit is completed. The discs 26, 27, 28 have insulating segments 33, 34, 35 offset which cause interruptions in the three records at different times to characterize them according to a code determined by the arrangement of insulating segments. In a second embodiment an auxiliary stylus applies a marking code to the curves which are not interrupted. The stylus 2 is connected to the contacts 20, 21, 22, whilst the drum 4 is connected to the terminal 32 through earth. The terminal 31 is also connected to a further brush moving with the brush 16 and cooperating successively with three contacts connected respectively to the brushes 23, 24, 25 which intermittently complete a recording circuit through isolated contacts carried by the discs 26, 27, 28 which are now of insulating material, the contacts being arranged according to the marking code. In a third embodiment the chart 3 is of a material in which the colour or thickness of the mark produced depends on the magnitude of the applied voltage. The stylus 2 is connected through the slip ring 30 to the brush 19 and the contact 20 is connected to the terminal 32, the contacts 21, 22 to tappings in a potential dividing resistor between the terminals 32, 31, the latter being connected to the drum 4.
Patent GB-133237-A (GB)
IPC: G01F23/44
Abstract: 133,237. Tanner, H. L. Jan. 21, 1919. Moving and changing apparatus.-Relates to an advertising system in which a number of movable members are operated selectively to display the notice. An electric apparatus consists of a transmitter adapted to selectively energize one or more of a number of electromagnets, the armatures of which control permutation bars or disks, thereby allowing one of a number of pointers to appear opposite its scale reading. In a modification, the magnets control perforated disks to selectively bring a set of perforations of the disks into aiinement, thereby exhibiting the markings on a disk placed behind the movable disks. In a further modification, a number of spring-controlled levers, bearing information, project from a casing and are normally held behind a screen by projections on magnet armatures. The ends of the lovers are cut away in various ways so that upon the energization of one or more ot the magnets a lever is operated to display the information. The permutation bars or disks may be operated by other than electrical means. The transmitter consists of four cam disks 57, 58, 59, 60, Figs. 4<a> and 5, adapted to close one or more of the switches 62, 63, 62<111>, 63<111>, in the circuits of the magnets 15, 16, 17, 18, Figs. 1 and 4<a>. The armatures of magnets 15 - - 18 are adapted tc operate permutation bars 4, 5, 6, 7, Fig. 2. Fifteen spring-controlled levers 2, Fig. 2, carrying pointers 2', bear against the permutation bars and in the normal condition the pointer 2<1> opposite the zero reading on the scale 8, Fig. 1, is visible. The operation of the transmitter energizes selectively one or more of the magnets 15 - - 18, thereby shifting the permutation bars to withdraw the pointer 2<1> opposite the zerc reading and to allow a pointer opposite another reading to become visible. One or both of the sides of the recesses in the permutation bars may be inclined. In the modification shown in Fig. 14, the bare are replaced by notched disks 70, 71, 72 adapted to be selectively operated by magnets 91, 92, 93. In the modification shown in Figs. 18 and 19, rotatable perforated disks 104, 105, 106 are placed over an information disk 103. The perforations in the rotatable disks are normally out of alinement, but upon the selective operation of the disks, by the magnets 113, 114, 115 one set of perforations, depending upon the combination operated, is alined to show the information, say the number 3, on the disk 103. In a further modification shown in Figs. 16 and 17, a number of levers 152, 153 - - 158 are provided with information at the outer ends 166 which are normally hidden behind a screen 161 on the casing 160. The inner ends of the levers are cut away as shown in Fig. 17, and bear upon projections 4<1>, 5<1>, 6<1>, of magnet armatures. When the magnets' 13<1>, 14<1>, 15<1> are selectively energized, one of the lever ends 166 is raised to display the information thereon.

Title: Improvements in or relating to servo assisted operating systems for brakes, clutchesand other devices
Inventor: DAVIES DAVID AUBREY
IPC: B60T13/24
Filed: 1961-04-13
Abstract: 936,256. Brakes. AUTOMOTIVE PRODUCTS CO. Ltd. April 12, 1962 [April 13, 1961], No. 13336/61. Class 103 (1). [Also in Group XXIV] A servo-assisted operating system for a brake, clutch or other control device comprises a lever mounted on a movable fulcrum and arranged to receive effort exerted by an operator to move the lever about the fulcrum and to transfer the applied effort to the device to be operated, a fluid-pressure servomotor acting on the lever to move it in the same direction about the fulcrum, and a control valve for the servomotor actuated by the reaction loads at the fulcrum to create a pressure differential in the servomotor for operating the latter, the control valve including a movable member subjected to a pressure corresponding to said pressure differential and which is arranged to oppose the reaction load at the fulcrum. As shown, a pedal 15 for operating a master cylinder 22 is fulcrumed at 11 on the short arm 12 of a lever 13 pivotally mounted at 14, the other arm 25 of lever 13 being operatively connected to control valve 26. When an operator applies pressure to the pedal the pressure built up in the master cylinder causes a reaction force at the fulcrum 11 which acts on the control valve to cause vacuum to be communicated to a vacuum servo 19 of the atmosphere-suspended type whereby the driven member 18 of the servo exerts a force on a rearwardly-extending part 16 of the pedal 15 in the same direction about the fulcrum 11 as the operator effort. This produces an increased reaction at the fulcrum 11 which, however, is balanced by pressure changes in the valve 26. As seen in Fig. 2, the valve is of the self-lapping type comprising a diaphragm 31, lower and upper plates 32, 33 being secured to the centre portion of the diaphragm and providing communication between the upper and lower chambers 28, 29 via a central opening in the lower plate and apertures 43 in the upper plate, chamber 28 being permanently connected to atmosphere. The central opening in the lower plate is formed in a depressed portion 41 of the plate which houses a valve element 38 normally closing the entrance to a vacuum pipe 37 and held in position by spring 39. An actuating stem 44 is secured to the upper plate, a spring 45 acting on the assembly to provide, through the stem 44 and lever 13, an initial resistance to operating forces. When the reaction force at fulcrum 11 is sufficient to overcome this initial resistance, the plates 32, 33 rise so that annular flange 42 of the lower plate engages valve element 38 to seal the lower chamber and subsequently lifts the element to communicate vacuum both to the lower chamber 29 and, via conduit 35, to the servomotor. This exerts a force on the plunger 44 opposing that due to the reaction force at the fulcrum 11 so that the valve subsequently laps and a progressive follow-up is provided by the servomotor according to the value of the reaction force.

Title: Improvements in the production of alkali metal salts of aci-nitro compounds
Filed: 1952-05-27
Abstract: A process for the production of alkali metal salts of nitroalkanes and nitro-cycloalkanes by the reaction of the nitro compounds with aqueous alkali solutions consists in causing caustic alkali solutions, preferably of greater concentration than 15 per cent by weight, to act on the nitro compounds in the presence of from about 0.5 to 10 per cent by weight of oximes with reference to the amount of nitro compound used.  Nitro compounds p  mentioned are the nitro derivatives of methane, ethane, cyclopentane, cyclohexane, cyclo-octane and their homologues, butanes, pentanes, decanes and hexadecanes, 2- and 1-nitropropanes and o -nitrotoluene.  Any aldehyde or ketone oxime, preferably that corresponding to the nitro compound, may be used.  In examples: (1) caustic soda solution is added to nitrocyclohexanone in which cyclohexanone oxime is dissolved, the sodium salt of aci-nitrocyclohexane being precipitated; (2) aqueous caustic potash solution is used in place of aqueous caustic soda; (3) aqueous caustic soda solution is added to a mixture of nitroalkanes (obtained by the gas-phase nitration of gasoline) containing dissolved acetone oxime, to give the sodium salts of the aci-nitroalkanes.

Title: Improvement in variable resistance devices
IPC: H01C10/42
Filed: 1943-08-18
Abstract: 567,767. Electric supply. JAKUBSKIND, R. Aug. 18, 1943, No. 13444. [Class 38 (iv)] [Also in Group XXXVI] A variable resistance device for controlling the current through a load over a wide range of values is arranged so that for low current values the device operates as a potentiometer and for larger values as a variable resistance in series with the load. Fig. 1 shows the circuit arrangement in which the resistance comprises two sections AB and CE, the latter having a tapping at D. The supply is connected across AE and the load between A and a movable contact K engaging the resistances. Points B, C, D, E are connected to the fixed contacts F, G, H, J of a double-pole switch which is automatically opened by the passage of contact K from section AB to section CE. With contact K on section AB, contacts FH and GJ would be bridged, thus short-circuiting DE and using AD as a potentiometer for supplying small currents to the load. When contact K passes to CD, the switch is opened as shown. This cuts out AB and places CE in series with contact K and the load. This allows greater load currents to be supplied up to the limit when K reaches E and the full supply voltage is directly across the load. The substitution of section DE for AB enables a change-over to be made without a sudden change in load current. Fig. 2 shows the variable resistance comprising sections 1, 2 and tapping 12. Sliding contact 13 is advanced by a lead screw 16 and carries a projection 19 for operating a double-pole switch 8 for changing over the windings. The supply is connected across 4, 5 and the load across 15, 4.
