Title: Method and device for maintaining stationary position of a ferromagnetic body freely floating in electromagnetic field
IPC: G05F7/00
Filed: 1961-11-28
Abstract: 941,568. Automatic position control. TESLA, NARODNI PODNIK. Nov. 28, 1961 [Nov. 28, 1960], No. 42465/61. Heading G3R. In a system for stabilizing the position of a magnetic body suspended in the field of an electromagnet, movement of the body relative to a tuned circuit varies the average amplitude of oscillations set up in the tuned circuit by a source of pulses having a frequency less than the resonant frequency, such variation being utilized to control the position of the body by controlling the energization of the electromagnet. In Fig. 5, a magnetic body 2, e.g. the rotor of an ultra high speed centrifuge, is suspended in an evacuated space by the resultant field produced by opposed electromagnetic coils 23, 24 the relative energization of which is controlled by a double triode valve 9. Deviations of the body from a desired position influence the damping of a tuned circuit 3,4 which is supplied from a pulse source 14 having a frequency less than the resonant frequency of the tuned circuit. The average amplitude of the train of damped oscillations in the tuned circuit is thus varied relative to the maximum amplitude. A direct voltage corresponding to the average amplitude is produced by a rectifier 12 associated with a resistance-capacity circuit 10, 11 having a small time constant, and a direct voltage corresponding to the maximum amplitude is produced by a rectifier 22 associated with a resistance-capacity circuit 20,21 having a large time constant. The two direct voltages are applied to the grids of double triode 9 to vary the relative energization of coils 23, 24 so as to correct the position of the body. A potentiometer 21 is provided so that the difference of the two voltages may be set near zero for greater sensitivity. Modifications are described in which (a) a single electromagnet is energized from an amplifier in accordance with the difference of the voltages corresponding to the maximum and average amplitudes of oscillation (b) the maximum amplitude of oscillation is stabilized by a clipping rectifier biased from a neon stabilized source (c) the energization of the electromagnet is controlled in dependence on the average amplitude of oscillation only.

Title: Automatic medicament injector
IPC: A61M5/20
Filed: 1964-10-19
Abstract: 1,041,920. Hypodermic syringes. S. J. SARNOFF. Oct. 19, 1964 [Oct. 18, 1963], No. 42484/64. Heading A5R. A hypodermic syringe comprises an injector gun having a plunger 28 which is projected in a barrel 26 by a spring 46 on releasing a detent 38, a cartridge holder 10, and a quick-action coupling means 22 connecting the holder and the gun by simple relative axial movement. The plunger 28 is slidable within the barrel 26 to the forward end of which a cartridge holder 10, comprising a head 14 and rearwardly directed fingers 18, is secured by a sleeve 22 which compresses the fingers about the barrel. At the rear end, the barrel has a threaded plug 34 having a pair of rearwardly directed stepped fingers 70 which co-operate with an abutment 42 projecting inwardly from the rear of an outer sleeve 30 which is slidable on the barrel. The plunger is slidable within the plug 34 and the abutment 42 and carries a spring detent 38. A compression spring 46 which bears against the plug and a collar 44 on the plunger is compressed on retracting the plunger, which is locked in retracted position by engagement between the detent and the plug. The plunger is released for ejecting medicament from the cartridge 52 by pressing the outer sleeve against a spring 40 forwardly relative to the barrel so that the abutment causes disengagement of the detent with the plug. The spring 46 projects the plunger and the piston 50 of the cartridge. The barrel is rotatable relative to the outer sleeve between a position in which a stepped portion 76 of each of the plug fingers engages the abutment, to prevent relative sliding movement of the barrel and the outer sleeve, and a position in which the plug fingers are aligned with recesses 74 on each side of the abutment, to permit relative sliding movement of the barrel and the outer sleeve for releasing the plunger. The relative angular positions of the barrel and outer sleeve are determined by the selective engagement of blocks 80 with pairs of opposed flat surfaces 88, 90 on the barrel having arcuate shoulders 92, 94. The speed at which the plunger is projected is adjusted by rotation of a ring 104 having an aperture of varying width which occludes an opening 102 in the forward portion of the barrel to a variable extent.

Title: Injection of oil into blast furnaces
IPC: C21B5/00
Filed: 1974-10-02
Abstract: 1485177 Burner control; blast furnace tuyeres F A K LUTH 2 Oct 1974 [4 Oct 1973] 42833/74 Headings F4B and F4T [Also in Division C7]  Pig iron is produced in a shaft furnace, e.g. a blast furnace, by the reduction of ore by coke and oil where the oil is introduced through a lance centrally located in a tuyere, wherein a cooling medium, e.g. water, is added to the oil when the oil feed rate falls below a predetermined figure in consequence upon a fall in the volume of heated blast air passing through the tuyere. By measuring the flow rate of the air, the amount of oil fed to the lance 3 is varied to ensure that the oil jets 6 issuing from nozzles 4 do not strike the walls of the tuyere. When flow-meter 11 detects a drop in volume of  blast air, control device 10 activates servomotor 14 which operates a shaft 15 to slightly close valve 18 to reduce the oil flow. When the volume of blast air drops such that the oil volume is reduced by 40-60%, further reduction would lead to overheating of the lance 3 and so the shaft 15 opens the water valve 16 which supplies water up to a total of 10% of the maximum oil volume.

Abstract: 1,136,626. Extraction of saponins and sapogenins. NATIONAL RESEARCH DEVELOPMENT CORP. 14 OCT., 1966 [22 Oct., 1965], No. 44939/65. Heading C2U. [Also in Division G6] Steroidal saponins or sapogenins are extracted from steroidal sapogenin-affording seeds by treating the seeds or portions thereof in an uncomminuted form (i.e. a form in which at least 50% by wt. of a sample is retained by a No. 30 sieve, British Standard 410) either with a saponin solvent to give a solution of saponin or with a substance capable of hydrolysing glycosidic linkages to give a hydrolysate containing sapogenin. The seeds may be those of the families Leguminosae, Balanitaceae or Zygophyllaceae, particularly the genera Trigonella, Trifolium and Balanites, and may be used as whole seed or whole embryo or broken seed or broken embryo. Fixed and volatile oil may first be removed from the seeds by a process which does not involve comminution, e.g. crushing, and the overall yield of sapogenin may be increased by incubating the seeds in the presence of an added aqueous medium prior to extraction or hydrolysis, and may also be increased if the incubation and/or hydrolysis is carried out in the presence of squalane or a steroid precursor on the saponin biosynthetic pathway e.q. squalene, geraniol, mevalonic acid or 3-methyl-but-3-enol or derivatives thereof, which precursor may be added in the form of a natural product containing it in an available form. Enzymes participating in the biosynthesis of squalane and steroids may also be added, and as an additional or alternative pre-treatment the seeds may be incubated with degrading enzymes such as cellulase or patinase. The process is particularly applicable to the recovery of sapogenins such as diosgenin, gitogenin and yamogenin from fenugreek (Trigonella foenumgraecum).

Abstract: 1,249,547. Transistor frequency sensitive switches. TELEFONAKTIEBOLAGET L. M. ERICSSON. 17 Sept., 1969 [26 Sept., 1968], No. 45916/69. Heading H3T. In a frequency sensitive switching circuit, a switch Ty is actuated by pulses derived from the signal E, whose frequency is to be detected, to connect the supply to a timer 1. If the frequency is below the predetermined frequency, capacitor C T  charges producing a signal which opens switch Ty, and the next pulse in the input signal recloses Ty. If the frequency of E s  is above the predetermined frequency, capacitor C T  cannot discharge between input pulses, no signal is produced to open Ty, and a delayed operate relay R is actuated to energize indicator L. When switch Ty closes, capacitor C T  charges through transistor T,1 which is cross-coupled with T r 2. The charging current cuts off both transistors, and a pulse is fed via transformer T to momentarily turn on transistor T r 3 to commutate Ty. Ty and T,3 may be replaced by a bistable circuit.
