Title: Improvements in or relating to gasfilled electric incandescent lamps
IPC: H01K1/56
Filed: 1938-11-26
Abstract: 502,078. Electric incandescent lamps with residual gases. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 26, 1938, No. 34494. Convention date, Nov. 29, 1937. Drawings to Specification. [Class 39 (ii)] In a gas-filled lamp having an operating pressure exceeding 4 atmospheres and with pieces of zirconium arranged in it for absorption of residual gases and impurities that exist in the lamp, the pieces of zirconium are so arranged in a space of the lamp that exhibits a temperature gradient that the temperature assumed by each of these pieces when the lamp is in use corresponds to the optimum temperature for the absorption of a given residual gas or of a given impurity by the zirconium. In an example two pieces of zirconium are arranged on one of the leading-in wires of a lamp comprising a tubular quartz bulb with a gas filling of krypton and nitrogen having an operating pressure of 25 atmospheres. The temperature gradient within the bulb is such that one piece of zirconium assumes a temperature of about 700 C., and the other a temperature of about 500 C., these pieces respectively being capable of absorbing any residual oxygen and hydrogen that may emanate from the quartz of the bulb. The temperature of the pieces of zirconium may be controlled at will by their disposition on the leading-in wires. Alternatively they may bo mounted on a specially provided supporting- rod, or in any other manner.

Title: Automotive engine and fuel injection pump therefor
IPC: F02M59/30
Filed: 1974-08-06
Abstract: 1472935 Fuel injection systems NISSAN MOTOR CO Ltd 6 Aug 1974 [20 Aug 1973] 34497/74 Headings F1A and F1B [Also in Division G3] A fuel injection system in combination with an I.C. engine comprises a fuel injection pump 10 having a shaft 12 rotatable about its axis, a control member 72 connected to control timing, duration and/or quantity of fuel discharged by the pump, a centrifugal governor 80 connected to actuate the control member 72 in response to the speed of the shaft 12; and a vacuum-operable actuator 134 adapted to be responsive to vacuum in an air intake conduit of an associated engine and connected to bodily move the centrifugal governor 80 and the control member 72 in response thereto. Increase of speed of shaft 12, and therefore shaft 76, which has an axial recess 92 for a pin 94 of the governor 80, causes flyweights 84, 86 to move outwards moving a sliding block 100 to the right so that lever 102 is rotated about a pin 118 on a sleeve 112 to move the control member 72 leftwards against springs 128, 130. Increase of engine intake vacuum communicated via port 156 to a compartment 140 causes a diaphragm 144 to move by means of a connecting rod 146, a connecting member (120) Fig. 3 (not shown) which moves flyweight carrier 82, sleeve 112 and spring seat member 126 to the left so that the control member 72 also moves to the left and the lever 102 moves so as to remain parallel to its original direction. Movement of the control member 72, which may be a rod co-operating with a rotary disc 68, as shown, or a rack engaging a pinion, causes rotation of plungers 22, Fig. 1 to control the fuel injection. The plungers have sloped top faces (64) Fig. 1a (not shown) so that the amount and timing of the fuel injection is dependent upon the plunger's angular position determined by the member 72. As the plunger is moved upwards by rotation of shaft 12, it forces fuel above it past a ball member 34 of a fuel delivery valve 26 until a groove (62) Fig. 1a is brought into alignment with fuel inlet port 46 supplied via fuel feed passageways 58 and 48, when further upward movement of the plunger 22 forces fuel through a channel (66), Fig. 1a to return to the passage 46 from which it passes via passageways 48 and 60 (Fig. 2) to the fuel reservoir (not shown).

Title: Improvements in or relating to method and apparatus for the treatment of butter
IPC: A01J15/12
Filed: 1945-12-20
Abstract: 614,549. Butter. STEVENS, A. H. (Cherry-Burrell Corporation, and Sugar Creek Creamery Co.). Dec. 20, 1945, No. 34511. [Class 84] [Also in Group XIII] Butter is continuously produced by a method wherein a portion of a dairy product containing milk fat in the dispersed phase is converted into an emulsion containing milk fat in the continuous phase, and said emulsion after mixing, if desired with water, salt or flavour starter, is then chilled under agitation partially to solidify at least some of the milk fat content thereof to produce butter, which is then subjected to a relatively quiescent undisturbed confined flow followed immediately by flow restricted sufficiently to produce turbulence whereby to disrupt the crystal structure of a substantial portion of the crystallized fat content of the butter and thus to develop a true butter texture in the butter. In a preferred method, 35 per cent cream is neutralised if necessary in pre-warming vat 10, Fig. 1, pumped through filter 13 together with steam from pipe 14 and is then pasteurised in flash type unit 16. The cream is then further heated in vacuum steam pasteurizer 23; which may be of the type described in U.S.A. Specification 2,022,420, under reduced pressure, and then passes to centrifuge 30 where it is concentrated to 80-98 per cent butter fat. After bulking in vessel 33 the cream passes to mixing chamber 37 in which salt or flavour starter may be added from reservoir 40. The mixture is then forced through the chilling unit 45 (see Group XIII) which converts it to butter which then passes into the texture developing unit 46, it being discharged through outlet 96. Unit 46 comprises an inner pipe 70 and a jacket 80. The butter passes down the pipe and is forced through three discs 92, 93, 94, fitted with a detachable disc member 74, Fig. 3, fitted with a restricted orifice 75 which may be slot shaped.

Abstract: The invention comprises compounds having the formula: <FORM:0865673/IV (b)/1> wherein R is hydrogen or the acyl radical of a hydrocarbon carboxylic acid containing 1-12 carbon atoms, R1 is an 11b -hydroxy or keto group and X is fluorine, chlorine, bromine, or iodine and a process for the production of a 3-keto-7-lower alkyl-D 4-cyclopentanophenanthrene compound which comprises reacting a 3-keto-D 4,6-compound otherwise unsubstituted in A and B rings with a lower alkyl Grignard compound in the presence of a cuprous chloride catalyst, the amount of Grignard reagent being in substantial molar excess of the steroid reactant.  As Grignard reagent there may be used methyl magnesium bromide. 7-lower alkyl-11b , 21-dihydroxy-4, 17(20)-pregnadiene-3-one or a 21-acylate thereof is oxidatively hydroxylated e.g. with osmium tetroxide and an oxidising agent to obtain a 7-lower alkyl-11b , 17a , 21-trihydroxy-4-pregnene-3, 20-dione, which may be oxidised to form the corresponding 11-keto compound.  Alternatively the 11-hydroxy compound may be dehydrated to obtain 7-lower alkyl-11b , 17a , 21-trihydroxy-4 9(11)-pregnadiene-3, 20-dione, 21 acylate which is reacted with Nbromoacetamide to obtain the corresponding 9a -bromo compound.  The 9a -bromo compound on treatment with potassium acetate gives a 9, 11b -oxido compound which with hydrogen fluoride gives 9a -fluoro-11b , 17a , 21- trihydroxy-4- pregnene-3, 20- dione.  Illustrative products of the invention are 7methyl-11b , 17a , 21-trihydroxy-4-pregnene-3, 20-dione, 7-methyl-17a , 21-dihydroxy-4-pregnene-3, 11, 20-trione, 7-methyl-9a -fluoro-11b , 17a , 21-trihydroxy-4-pregnene-4, 17(20)-[cis]-pregnadiene-3-one and the 21-acetates thereof. Specification 749.201 is referred to.ALSO:Pharmaceutical compositions incorporating 7-lower alkyl - 11b , 17a , 21 - trihydroxy - 4 - pregnene - 3,20 - diene and 7 - lower alkyl - 17a ,21-dihydroxy - 4 - pregnene - 3,11,20 - trione and their 21-esters are employed in ointments, creams, lotions and sprays.  Antibiotics such as penicillins, neomycin, tetracycline and chloramphenicol may also be present.  Specification 749,201 is referred to.

Abstract: 417,820. Screwing die - heads. WAGNER MASCHINENFABRIK, G., 11, Opfersteinstrasse, Reutlingen, Wurtemberg, Germany. Dec. 11, 1933, No. 34809. Convention date, Jan. 23. [Class 83 (iii).] Pivoted - carrier screwing die - heads have recesses 9<1> in the chaser-carriers 5 which engage a large flange 3 on a bush 2 mounted in the body 1, so as to guide and support the chasers immediately behind the cutting edges throughout their range of adjustment. The flange 3 is disposed forwardly of the front face of the body and obviates the necessity for guides for the carriers on said face, thus leaving the pivot pins 4 free in the body. The carriers are supported during cutting by a cam-ring 8 rotatable on an axially slidable sleeve 6 by means of a key 12 having teeth engaging a gear ring 14 on the ring 8 and insertable in a recess 11 in the sleeve 6. Axial motion of the ring 8 on the sleeve 6 is prevented by collars 16 on bolts 17 engaging an annular groove 18 in the sleeve. The chasers 15 are held in undercut recesses 19 in the holders 5 by means of plates 21. The Specification as open to inspection under Sect. 91 states that the invention was also applicable to die-heads having radial chasers: This subject-matter does not appear in the Specification as accepted.

Title: Phase Detector
Inventor: SOMMERUD ROLF GUNNAR
IPC: G01R25/00
Filed: 1967-07-28
Abstract: 1,186,690. Phase detectors. INTERNATIONAL STANDARD ELECTRIC CORP. 28 July, 1967 [19 Aug., 1966], No. 34810/67. Heading G4H. In apparatus for measuring the phase between two frequency signals n 1 F, n 2 F having a common harmonic frequency nF, the first signal n 1 F is fed to an AND-gate 14 so-that the first positive-going edge of the signal after a start pulse sets a bi-stable 16 to its one stable state to enable an AND-gate 17 to pass clock pulses -at frequency NF, (N # n 1 n 2 ) to a counter 2 which counts from 0 to N/n -1 and then recycles. The first positive-going edge of the second signal n 2 F resets the bi-stable device 16 to stop the count, which then represents the phase difference measured in degrees with respect to the common harmonic frequency nF of the two signals n 1 F, n 2 F. To derive the average phase difference from e.g. 5 phase difference samples taken at intervals of K/F seconds, where K is an integer, a divider (21, Fig. 3, not shown) dividing the output of AND-gate 17 may precede the counter.

Filed: 1966-08-05
Abstract: 1,189,127. Electric extensometer. COURTAULDS Ltd. Aug. 4, 1967 [Aug. 5, 1966], No. 35110/66. Heading G1N. An extensometer producing a voltage proportional to length variations of a test article has the change in output voltage due to a selected percentage change in length, adjustable to a desired value. The end of a filament undergoing a tensile test is attached to the wiper 1 of a potentiometer RV1 which has potentials E1, E2 applied to its opposite ends, the potential E2 being controlled by amplifiers A2, A4 to produce zero voltage on the wiper when it is in a position 1b corresponding to the initial length of the filament, E2 being thereafter constant while the wiper follows extension of the filament (position 1c) and applies a voltage to a capacitor C2. The voltage of C2 is subsequently compared at 8, by changing over switch G1, with the potential of a wiper 9 of a second potentiometer RV2 driven by a motor which stops whenthe output of the comparator 8 is zero. The wiper 9 is coupled to an indicator drum calibrated in % extension. The filament is pretensioned to remove crimps, &c, thus moving wiper 1 from a position 1a to the starting position 1b the switch W1 being in the position shown to produce the value of E2 required to give zero volts on the wiper at 1b, the capacitor C1 serving to maintain the value of E2 when switch W1 is opened. A circuit A revives the potential E1 from a stabilized voltage E3 applied to the second potentiometer RV2, and a circuit B defines the output sensitivity of the potentiometer RV1, both circuits having adjustable resistors R1, R2, R3, R4 to vary the range and sensitivity of the extensometer.
