Title: Telegraph exchange system
IPC: H04L12/00
Filed: 1938-05-19
Abstract: 501,705. Telegraph exchange systems. LORENZ AKT.-GES., C. May 19, 1938, No. 14979. Convention date, May 19, 1937. [Class 40 (iii)] A selecting dial is locked until a first group selector is engaged, and is released from the automatic exchange, Fig. 2, by an increase of the current in the subscriber's line a, b. When a ringing key AT, Fig. 1, is pressed, the first stage of a two-stage relay W responds and bridges the calling key, and a relay E, Fig. 2, connects a relay R to the current supply. This connects the rotary magnet D of the preselector, and, when a free bank of contacts is found by the brushes a1 .. d, a relay T is energized. A resistance w3 is thus bridged to increase the current in the subscribers' line. This completes the energizing of the relay W, which releases the dial and connects a busy lamp L to the mains Ne to indicate that selection can begin. The relay T also disconnects the rotary magnet and applies reversed current to relays S, L, which reverse the current in the subscribers' line. A polarised relay P responds and connects a magnet H to the mains to connect the motor M of the printing telegraph machine to the mains and a transmitting contact SK and receiving magnet EM to the subscriber's circuit. The relay W drops and locks the dial to prevent interference with the communication' by dialling. At the end of communication, pressing a key ST interrupts the subscriber's loop.

Title: Improvements in or relating to the separation of a c rich fraction from highly cracked distillates
IPC: F25J3/02
Filed: 1954-05-21
Abstract: A C2 rich fraction is isolated from a cracked hydrocarbon stock by fractionating the stock, collecting a volatile fraction comprising all the C2, C3 and C4 components, cooling and compressing the fraction and contacting it with a hydrocarbon liquid under such conditions that the C2 component is substantially in the <FORM:0753773/IV(a)/1> vapour phase and the components heavier than C2 are substantially absorbed and recovering the gaseous C2 rich fraction.  In a preferred embodiment an initial total naphtha, heavy naphtha, kerosene, gas oil or heavier petroleum feed is fed to a cracking unit 2 for cracking at 1000-1400 DEG  F., steam may be added.  The cracked effluent passes through a line 3 to a primary fractionator 4 from which an overhead fraction boiling at 490-460 DEG F. is passed by a line 7 through a cooler 8 to a receiver 9 from which part of the condensate is refluxed through a line 10 to the fractionator 4.  Hydrocarbons boiling up to about 120 DEG  F. are passed through line 14 into a compressor 15 and a cooler 16.  The uncondensed C1 to C4 gaseous hydrocarbons are passed from tank 13 to a sulphur removing unit 18 and then the streams pass to an absorber 20 in which the C2 components are chiefly separated. This is effected by adding low boiling absorbent oil of mainly C5 components by line 21 and removing a top overhead stream at 60-75 DEG  F. by line 29 to a second absorber 30 in which a more nonvolatile oil absorbent is utilized.  The C1 and C2 fraction is taken overhead at about 70 DEG F.

Title: Transistor system for generating a periodic scanning current in an inductive winding
IPC: H04N3/18
Filed: 1958-05-14
Abstract: 842,296. Transistor saw-tooth wave circuits. HAZELTINE CORPORATION. May 14, 1958 [May 29, 1957], No. 15547/58. Class 40(6). [Also in Groups XXXV and XXXVI] The turn off characteristic of a junction transistor feeding an inductive load is improved by connecting a junction rectifier to the load so that it stores charge carriers while the transistor is conductive and discharges the carriers into the load while the transistor is being turned off. The figure shows a sawtooth current generator in which the line deflection coils are coupled across winding 36 of an auto transformer connected in the collector circuit of a junction power transistor 32. At the beginning of the sweep, energy stored in the inductive output circuit is discharged through a junction rectifier 40 so that the first part of the sweep is produced by this current together with a small current flowing in the transistor collector circuit. The collector current then increases and the latter part of the sawtooth is produced by this current. Towards the end of the sweep the drive voltage at the base causes the base current to reverse to remove the stored carriers so that the collector current commences to decrease although relatively slowly. During this period carriers stored in the junction rectifier 40 are also discharged and this continues the linear increase in current in the output circuit until the rectifier is fully discharged. By this time the transistor current has decreased to a low value so that a rapid reduction of output current is obtained to initiate the flyback. The output winding 36 is tuned by capacitance 39 to a frequency approximately five times the scanning repetition frequency and rectifiers 54 and 51 are connected to additional windings to provide two different values of high voltage from the flyback pulses. Circuits 43 and 47 provide voltages for the radio frequency and video frequency amplifiers respectively of the television receiver by rectifying the transformer output voltage during the forward stroke. The pulse input for transistor 32 is derived from a sine wave input at 25 by a circuit comprising transistor 67 and an auto transformer 90 the output winding of the transformer being series tuned by a capacitor 70 to the sawtooth repetition frequency. A damped inductor 72 stores energy during the flyback and feeds it to the transistor during the forward stroke so as to enhance the carrier storage of the transistor. In addition, a large voltage is induced across the inductance during the time the transistor is turning off and this improves the turn off speed.

Title: A method for electroplating objects with a successive bright nickel and chromium coatings, as well as objects covered by applying this method
IPC: C25D15/02
Filed: 1963-04-19
Abstract: In electroplating objects with successive coatings of bright nickel and chromium, the nickel layer is deposited from a bright nickel bath containing dispersed solid insoluble particles in a concentration c in g/1 not greater than 20 dS where d is the effective mean diameter of the particles in microns and s is the specific gravity of the particles. Where the particles are aspherical d is the diameter of the sphere of the same volume as the particle.  The smaller the particles the greater is the dulling effect on the nickel plate. Specified examples of suitable particles are quartz and glass powders, china clay, Al2O3, CeO2, Fe2O3, Cr2O3, B4C, SiC, CaCO3, BaSO4Nc(OH)2, MoS2. Reference is also made to the use of diamond powder, filtering earth and molybdenum oxide. In examples Watts nickel baths are used containing as brighteners saccharin and butynediol or naphthalene disulphonic acid and propargyl alcohol.

Title: Improvements in and relating to apparatus for applying plastic coatings to articles such as bread slices or jointing material
IPC: A21C15/00
Filed: 1932-06-01
Abstract: <PICT:0402756/III/1> <PICT:0402756/III/2> A machine for spreading plastic material upon articles, e.g. butter upon bread slices, grease or grease and graphite upon jointing-material, comprises a container 1, electrically heated if required, for the plastic material and a plunger 2 for ejecting the material through the outlets 4, the plunger 2 being spring-loaded.  Means are associated with the plunger whereby the master valve is more fully opened as the plunger advances, to compensate for the loss of power of the spring.  The means in Fig. 2 comprise a cam 29 adjustably carried by the plunger so as to contact with the edge of an opening 30 in the rotary valve 16. The valve 16 is initially set according to the thickness of the required layer of plastic material or the plasticity thereof, by an external handle, and, as the plunger 2 descends, the cam 29 increases the opening through the valve.  The outlets 4 are controlled by valves 3, spring loaded and balanced, if desired, carrying shoes 6 which engage the articles to be coated.  Valves 3, according to the shape of the articles, are thus opened, and the material is spread by a member 7.  The article is placed on a resilient table 8, or on suitable feed rollers 9, 10 and fed up to the shoes 6 where they are engaged by the main feed roller 11 which may be resiliently mounted. The discharge table 12 is also spring-mounted.  Fig. 7 shows a modification of the compensating-mechanism, a cone 32 being adjustable on a rod carried by the plunger.  The master valve 16 is actuated by a spring 36, and is controlled by a roller 37, bearing on the cone 32, and linkage 33, 34.  An endless belt may be used to feed the slices.  According to the Provisional Specification, the plunger may be weight-loaded, or operated by compressed gas.

Abstract: 465,851. Kinematograph apparatus. FACIN FABRICATION D'APPAREILS DE CINEMATOGRAPHIE, and WEISSBRODT, J. E. June 4, 1936, No. 15610. [Class 97 (i)] Relative movements of shutter members to obtain fade-out and like effects are produced by mechanism driven by the motor of the apparatus and controlled by a bent lever ; the speed of the relative movements may be variable, and means for producing them manually may be provided. The shutter members may comprise discs 1, 2, respectively carried by hubs 4, 5 frictionally mounted on a longitudinally-movable shaft 3 having a pin extending into a longitudinal slit in the hub 5 and into a helical slit in the hub 4. A fork 28 on a shaft 26 engages a grooved ring 6 on the shaft 3 ; rocking movement of the shaft 26 thus causes longitudinal movement of the shaft 3 and variation of the shutter opening. The shaft 26 may be rocked by a crank 27 linked to a rod 31 guided by a shaft 18 and moved by a pin 32 engaging a cam groove 22 in a disc 21. The disc 21 may be rotated by the motor through gears 9, 10, change-speed gearing 16, 17, and a gear 20, or by hand through a knob 19 on the shaft 18. The change-speed gears 16, 17 are carried on a frame 14 pivoted on the shaft 11 and normally supported by the end 23 of one arm of a bent lever 24 held by a spring 25 but capable of being depressed by a rod carrying a push button 34. Depression of the lever 24 permits the wheel 17 to engage and drive the gear 20, thus causing relative rotation of the shutter members, first to reduce and close the shutter opening, and then, during the completion of one rotation of the gear 20, to open it to the original extent. The other arm of the lever 24 terminates in a finger 38 normally engaging a nose 37 of a cam 30 loose on the shaft 26. The cam is linked to the pin of the crank 27 by a spring 36<1> and moves with it when released by movement of the finger 38 ; the curved surface of the cam 30 then engages the finger 38 and prevents the return of the lever, and consequent disengagement of the gears 17, 20, until one rotation of the gear 20 has been completed. The gears 17 are integral with one another, and the gears 16 may be coupled singly to the shaft 11, variation of the coupling, to effect change of speed, being obtained by operation of the knob 43. A modification is described in which the cam 30 is replaced by a sliding shoe.
