Title: Improvements in liquid fuel injecting and reversing devices for internal combustion engines
IPC: F01L13/00
Filed: 1921-03-08
Abstract: 181,447. Murphy, J. F. March 8, 1921. Regulating.-In a twostroke multicylinder engine which ignites its charges by the heat of compression and using burnt gases trapped from the combustion chamber of one cylinder to inject fuel into another cylinder, the fuel is delivered by a pipe 32 past the needle valve 29 into the chamber 23, which adjoins the valve 24. By this means, the power output of the engine is kept approximately constant irrespective of load, since the flow of fuel past the needle valve is independent of the engine speed and of the load. The needle valves for all the cylinders may be simultaneously set by hand, and the engine may run in either direction.

Title: Improvements in and relating to high frequency signalling systems
IPC: H04B3/20
Filed: 1931-03-13
Abstract: 358,855. Wireless and wired wireless signalling. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Rives, F. M.; 215, Pawling Avenue, Troy, New York, U.S.A.) March 13, 1931, No. 7817. Convention date, March 20, 1930. [Classes 40 (iii) and 40 (v).] In a two-way signalling system the transmitter is arranged to render the receiving amplifier insensitive during transmission. The Figure shows an oscillator 24 having a valve 27 in its plate path which inhibits oscillation except when signals are present in amplifier 28. When signals are present the oscillator produces a voltage in resistance 23 which applies a positive voltage to the receiving amplifying valves 12, 14 which renders these valves inoperative without producing key clicks. Modulation of the oscillator may be effected by means (not shown) of the type described in Specification 299,316, [Class 40 (v), Wireless signalling &c.]. The filter 11 comprises a plurality of loosely coupled coils 18 each tuned by a condenser 19 the coils being adjustably mounted on a common support 22 to provide the desired magnetic and capacitive coupling. The condensers 19 are ganged but the link circuit input is separately tuned. The input coil 21 is of smaller diameter and concentric with the first coil 18 to give a tight coupling. A screen grid valve 12 is used in the first stage of the aperiodic high-frequency amplifier to avoid damping the last tuned circuit of the filter. The second valve 14 is a triode as this type of valve is more susceptible to grid-bias control. The detector 16 is of the bottom bend type and the bias produced by grid current in resistance 32 will vary with input and is arranged to maintain the output constant.

Title: Improvements in or relating to textile drafting mechanism
IPC: D01H5/50
Filed: 1958-03-11
Abstract: 885,974. Drafting rollers. S.K.F. KUGELLAGERFABRIKEN G.m.b.H. March 11, 1958 [March 29, 1957; Nov. 6, 1957], No. 7840/58. Class 120(2) A textile drafting mechanism having a pivotally mounted top-roll carrier arm which can be locked in the operating position to a stationary part of the machine and which has, for each associated top roll, a guide arm so mounted as to permit pivotal movement thereof transversely to the plane of the drafting field and through which weighting pressure is transmitted to the top roll, at least one such guide arm being mounted in a manner permitting it to perform a lateral swing- ing movement parallel to the plane of the drafting field in addition to its pivotal movement, is modified so that the guide arm is supported in the carrier arm by a pair of retaining members mounted directly (or indirectly through a holder) in the guide arm (or the holder) and has point or line contact with the retaining members to permit the lateral swinging movement, and the weighting means partakes of this latter movement. In the mechanism of Fig. 1, a stirrup 4 comprises pivot pins 7 as retaining members embraced by tongues 8 on a holder 9 which carries on arms 9<SP>1</SP> a pivot pin 10 receiving a guide arm 11 constructed as a saddle support for top roll 13, a "weighting" spring 15 being seated at 14 and 14<SP>1</SP>. The swing of arm 11 about pivot 10 is limited by engagement of an abutment 17 with stop lug 18. Lateral swinging parallel to the plane of the drafting field by holder 9 (together with spring 15) is permitted by reception of ribs 8<SP>1</SP> in recesses in pins 7, so that roll 13 may automatically align with its axis parallel to axis of bottom roll 16. Stirrups 4 adjacent to support bar 1 pivot only transversely to the plane of the field. In another mechanism, Fig. 2, arm 2 mounts pivot pins 22 recesses of which are engaged by ribs 23<SP>1</SP> of tongues 23 to permit the lateral swinging of holder 21. A spring 25 is seated, at 26 and 26<SP>1</SP>, between holder 21 and the guide arm 28 pivotal movement of which (following release of a locking device 3) is limited by engagement of hooked lugs 29 under a web 30. Guide arms 28 adjacent to bar 1 are each pivoted on a pin 32 in a holder 33 and springs 25<SP>1</SP> rest against seatings in holder 33 and guide arm 28<SP>1</SP> the swing of which is limited by engagement with holder at 34. In the mechanism shown in Fig. 4, adjustable stirrups 4 each mount pivot pins 7 engaged by ribs 36 of tongues in guide arms 35 to permit the latter to swing laterally. The resiliency of the arms 35 permits pivoting of the limb carrying the top roll transversely to the plane of the drafting field, this movement being limited by coacting slot 37 and loop 39 which reaches under lug 38. This resiliency also applies "weighting" pressure (to the top roll) which may be augmented by a leaf spring 40 or helical springs, Figs. 6 and 9 (not shown), especially for the arm remote from bar 1.

Title: Process of converting hydrocarbons into lighter hydrocarbons
Filed: 1929-03-11
Abstract: 330,570. Losey, A., Gottlieb, P., and Haupt, L. L. Jan. 7, 1929, [Convention date]. Hydrocarbons, distilling.-In cracking hydrocarbons, catalytically treated hydrocarbon condensate is subjected to the action of the heat of a separate flow of hydrocarbon vapours which are thereby fractionally condensed. Crude petroleum heated to about 800‹ F. in a, coil 4 passes down a pipe 6 from which the vapours pass into a compartment 7 and the residues through a pipe 9 into a compartment 10 of a fractionating and converting column 8. The column 8 is provided with a converting element 47 comprising pipes which pass through compartments 10, 7, 19, 25. 31, 37 formed by trays 15, 21, 27, 33, 39 and a bottom 11. A catalyst such as aluminium chloride supplied from a tank 44. is mixed at the commencement of operations with hydrocarbon condensate supplied from an outside source by a pipe 48 and passes down the pipe of the element 47, receiving the heat necessary for the cracking of the hydrocarbon from the ascending vapours which enter at the pipe 6; the ascending vapours are thus cooled and deposit successively in the trays 15, 21, 27, 33, 39 fuel oil, lubricating stock, distillate, gas oil and kerosene. Light vapours escape from the column 8 by a pipe 41 and deposit commercial gasoline in a condenser 42. The cracking in the element 47 causes increased pressure therein and the vapours formed in the various compartments are led by bleeder tubes 51 to a central passage 53 and conduit 54 to a high pressure condensate collector 55 in a column 56. The vapours from the collector 56 pass in succession to collectors 65 - - 68 through cylinders 57 - - 60 of engines 61 - - 64 wherein they experience thermodynamic heat drops and finally operate a turbine 72 before depositing in a chamber 74 condensate which is fed through pipes 88, 82 to be mixed with the catalyst in place of the condensate from the outside source which is therefore dispensed with. Un-condensed vapours pass to a vacuum condenser 76 where gasoline is deposited. Condensate collects in each of the collectors 55, 65 - - 68 and is returned to the corresponding part of the element 47 by pipes 78 - - 82. the supply being augmented by additions from the various travs in the column 8 if necessary. The catalyst. if volatile, returns along - the pipe 78 to the column 8. The residues which collect in the bottom 11 of the column 8 from the column and the pipe 6 are led to a second heating coil 97 where they are heated to 950<‹> F. before passage to the compartment 10 of the column 8 in which they transfer heat to the lowest part of the element 47 before mingling with the vapours entering by the pipe 6.
