Abstract: 690,035. Automatic control systems for hoists. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 19, 1950 [Nov. 2, 1949], No. 28089/49. Class 38 (iv). [Also in Group XXXVII] The speed of an induction motor 1 driving a hoist is measured by a tachometer generator 13, the output of which is compared with a reference voltage tapped off potentiometer 17, any difference being amplified by transductors 20, 21 to control the coil 22 and hydraulic servomotor 24 which correctively varies the resistor 8 in the rotor circuit. The reference voltage is varied by a cam 19 according to the position of the hoist cage to suitably accelerate and slow down the cage. If the tachometer output exceeds the reference voltage, rectifier 39 conducts and transductor 38 actuates the dynamic braking relay OCD connecting the stator of the motor to a grid-controlled rectifier 11. The D.C. excitation current is made proportional to (or a non-linear function of), the rotor current by controlling the rectifier according to the rectified and amplified output of current transformers 33. This output is also applied via transductor 37 to the rotor resistor controlling transductor 21 to prevent a predetermined rotor current from being exceeded. The limiting current is determined either by a polarized rectifier limiter on the input to transductor 37 or, Fig. 2 (not shown), the transductor 37 is arranged so that the impedance of the output winding increases abruptly when the current in the control winding falls below a predetermined critical value. Specifications 645,019, 651,379, [Group XXXVII], and 690,090 are referred to.

Title: Improvements in or relating to plunger pumps
IPC: F04B9/04
Filed: 1938-09-26
Abstract: 519,826. Fuel injection pumps. HANDELSAKTIEBOLAGET VIDAR. Sept. 26, 1938, No. 28045. Convention date, Sept. 28, 1937. [Class 102 (i)] In a fuel injection pump for an internal combustion engine having four or more motor cylinders, the pump comprises two or more pump -cylinders 2, 2a the plungers 3, 3a of which are driven from two or more cams 5, 5a mounted on a cam shaft 6 and each formed with two or more compression steps 62-64 or 62a-64a and one suction step 65 or 65a, the compression and suction steps of each cam are angularly displaced in relation to those of the other cams, so that two or more but not all of the motor cylinders fed from the pump are supplied with fuel in a definite order of sequence from the same pump pressure chamber 23 or 23a during each compression stroke of the pump, and so that the suction periods of the different pressure chambers are displayed in relation to one another. With the two cams shown in Fig. 4, two pump cylinders deliver alternately. Two other arrangements providing . different sequences are described and illustrated in the Specification. Each of the pump units shown in Fig. 1 are of the kind described in Specification 519,645. Turning of the plungers 3, 3a to control their deliveries is effected by pins 3c and 3ca on the plungers projecting into slots in toothed segments 32, 32a Fig. 3, which engage teeth 36, 36a on two rack parts 31, 31a which are urged to the right by springs 35, 39, a pin 31b or part 31 passing through the part 31a, and a threaded part 37 being engaged by an adjusting nut 38 which determines the relative angular setting of the two plungers. The two rack parts are moved together to the left by a pivoted lever 55 controlled by a stop 56 and operated by a spring- pressed piston 51 subject to the vacuum in the intake passage of the engine. Delivery by the plunger 3 may be cut off by engagement of the pin 31b by the armature 76 of an automatic or manually controlled solenoid 71. The Specification as open to inspection under Sect. 91 comprises also a modification in which the piston 51 acts directly on a one-piece rack, and the solenoid is located directly above the suction valve 9, a pin-like portion of the solenoid forcing the valve off its seating. This subjectmatter does not appear in the Specification as accepted.
Patent GB-759720-A (GB)
Title: Improvements in or relating to process of coking residual oils
IPC: C10B55/10
Filed: 1954-10-05
Abstract: <PICT:0759720/III/1> In coking heavy hydrocarbons by contacting them with preheated finely divided fluidized solid particles, the maximum feed rate of oil to the bed without causing agglomeration is determined by a equation based on the facts that the rate is inversely proportional to the coke deposited and that this coke yield is proportional to the Conradson carbon number of the feed.  Sand, pumice, metal shot, glass or ceramic beads &c. may be used but coke of 40-500 microns diameter derived from the process is preferred for the bed and partially burnt to provide a bed temperature of e.g., 800 DEG -1000 DEG F for a maximum yield of gas oil. Apparatus comprises a preheater 11 from which the solids are conveyed by steam, nitrogen, &c. through a line 13 to a coking vessel 15.  Oil, preferably preheated to below cracking temperature, is supplied through valved nozzles 20 into the bed the level of which is determined by a partition 25 defining a stripping zone 27, solids returning therethrough and through a line 37 to the heater assisted by air, &c. admitted at points 41. Gas or oil fuel may be supplied to reduce or eliminate coke combustion.  Coking bed temperatures of 900 DEG -1050 DEG F are preferred and with feed preheat of 600 DEG -800 DEG F and aerating velocity of 0.5-1.2 ft. per sec. a maximum coke deposit of 0.35 lb. per hour per lb of fluidized solids may safely be reached. Increases of 30 DEG -50 DEG F in coking temperature enable the oil feed rate to be doubled.

Abstract: 1,082,496. Forming glass fibre mats. GLASWERK SCHULLER G.m.b.H. July 10, 1964 [July 11, 1963], No. 28685/64. Headings DIN and D1R. Apparatus for the production of mats of glass fibres includes a cutting device and one or more delivery tubes along which the cut fibres are blown, each tube having its orifice adapted to carry out a rectilinear traversing motion. In the form of apparatus shown, rovings enter a cutting device 4 at the positions 5 and the cut fibres are blown into a delivery tube 9 by an air stream generated by the rotary knives and supplemented by a fan 7. The tube 9 is slidably mounted on a pivot 14 and guided in a rectilinear traversing motion by guides 12. At the orifice end 16 of the tube there is connected a tube section 17 of larger diameter in such manner that ambient air enters the section 17 to ensure disintegration of glass fibre clumps. A suction drum 20 transports fibres to a conveyor belt 1. A modification has the delivery tube almost wholly enclosed in a tube of larger diameter. In another arrangement, the cut fibres are deposited directly on a conveyor belt from more than one discharge tube. The movements of the discharge tubes are so phased that fibres are simultaneously laid in different lateral positions on the conveyor belt. Baffles are provided at the ends of the tubes. Mats having layers of fibres of different lengths or fineness may be formed. To reduce electrostatic charging, the air conveying the cut fibres has its moisture content increased.

Title: Flow control valves
IPC: F16K1/52
Filed: 1954-10-11
Abstract: 757,779. Valves. SULZER FRERES SOC. ANON. Oct. 11, 1954 [Nov. 3, 1953], No. 29190/54. Class 135. A flow control valve having a valve member 3 connected by a stem 5 to an actuating .piston 7 under the control of a pilot valve 9 has a manuallyadjustable first stop member 11 for limiting the movement of the valve member and a second stop member 20 for limiting the movement of the first stop member. The stop member 11 forming part of an internally - threaded sleeve 12 is movable axially, relative to upper and lower abutments carried by the piston, by the rotation of a screw 14, whilst the stop member 20 slidable on pillars 17 between collars 18, 19 can be clamped to the sleeve 12 in either of two notches 21, 22. The stop 11 normally occupies a position between the piston abutments whereby the downward movement of the piston is limited by the seating of the valve and its upward movement by the engagement of the lower abutment by the stop 11. With the stop 20 in its chain-dotted position further opening of the valve is prevented by the collars 18, the valve may however be closed manually in an emergency by rotation of the screw 14 causing downward movement of the stop 20 on the pillars 17, the stop 11 engaging the lower abutment to move the piston and valve downwardly. With the stop 20 in its full line position full closure of the valve is prevented by the collars 19 but the valve may be moved further in an opening direction on rotation of the screw 14.
