Filed: 1949-08-23
Abstract: 667,793. Curds and whey food. BERNAT, R., and BERNAT, H. Aug. 23, 1949, No. 21892/49. Class 49. Milk is completely curdled, e.g. by rennin, the curds separated from the whey, the whey concentrated until pasty, and the drained curds and concentrated whey are mixed together with sufficient sugar to ensure preservation of the product and a flavouring substance. Concentration of the whey may be effected by freezing while agitating, and filtering off the ice crystals formed. The preferred sugar is sucrose, used in an amount at least equal to the weight of the drained curds. The flavourings are exemplified by those of cocoa, coffee, and liqueurs or spirits. Gelling substances, exemplified by agar-agar, gum tragacanth, gelatine, and pectin, may be added.

Filed: 1939-07-27
Abstract: 531,604. Arc lamps. WARREN, S. F. (Warner Bros. Pictures, Inc.). July 27, 1939, No. 21895. [Class 39 (i)] Mechanism for simultaneously feeding the carbons and rotating the positive carbon is so arranged that the relation between the feed and the rotation can be regulated. For this purpose the positive carbon 10 is gripped between toothed wheels 108, 109 carried on spindles in a rotating head 106 and drawn towards each other by springs. The head 106 is mounted on a hollow shaft 102 driven from a motor 61 through gear boxes 69, 71 a rotating, telescopically-jointed rod 72, and gear wheels 105, 137. The wheels 108, 109 engage a spiral scroll on the face of a member 116 mounted on the shaft 102 and normally rotating with it. A cam surface 123 carried by the gear wheel 105 allows a screw 133 carried on a spring-pressed member 126 to engage at regular intervals with teeth 122 on the edge of the member 116 and stop its rotation, so that the wheels 107, 108 rotate and feed the carbon. The period of this engagement can be regulated by adjusting screw 133. The negative electrode 15 is fed by toothed wheels 38, 43 engaging it and driven by worms 33, 34. The negative electrode holder is mounted on a lever 26 actuated by a spring 51 to bring the carbons together. When the current is switched on a lever 26 is moved by an electromagnet 13, striking the arc. Current is supplied to the electrodes by brushes 45, 18.

Abstract: 179,476. Davey, Paxman, & Co., Ltd., Taylor, J., and Barnes, C. Aug. 18, 1921. Equalizing action of two governors controlling two coupled units. -The two inertia governors of two coupled units which it is desired should run in unison have their inertia rings 1 coupled together to ensure synchronous action of the two elements notwithstanding any small differences in the characteristics of the two governors. Any relative rotational motion between the inertia ring 1 and the driving-shaft 5 causes axial movement of a spindle 16, contained in a hollow extension 17 of the driving-shaft, by a nut 13, attached to the boss 3 in connection with the ring 1, engaging right-handed threads formed on an enlarged portion 15 of the spindle. Axial movement of the spindle 16 causes angular motion of the shaft 20 through a cotter 19 connecting the spindle to a grooved sleeve 18 sliding on the extension 17 and engaging a forked arm 21 attached to the shaft 20. The second governor ring is connected up to the shaft 20 in a similar manner, as shown by Fig. 3, with the exception that the thread 15 on the spindle is left-handed.

Title: Manufacture of pure compounds of the cyclopentanopolyhydrophenanthrene series
IPC: C07J5/00
Filed: 1939-07-28
Abstract: 536,210. Cyclopentanophenanthrene compounds. FAIRBROTHER, H. (Naamlooze Vennootschap Organon). July 28, 1939, Nos. 22011 and 25986. [Class 2 (iii)] Cyclopentanopolyhydrophenanthrene compounds which contain a -COÀR group in the 17- position (R being alkyl) are oxidized by lead tetracetate to produce oxidation products in which either or both the R group and the hydrogen atom in the 17-position is or are substituted by acetyl groups, and these compounds are separated from the other products of the reaction by a process of chromatographic selection. The preferred method of procedure is to treat the starting material with lead tetracetate in glacial acetic acid solution, the optimum conditions of reaction for the particular starting material being determined by trial using varying concentrations of reagents under varying temperature conditions. The resulting products may be saponified if desired. In examples (1) Progesterone is treated with lead tetracetate in glacial acetic acid solution for 7 hours at 80‹C. and the resulting syrup chromatographed to yield a principal product of desoxycorticosterone acetate ; (2) Allopregnane-3-acetoxy-21-one is treated with lead tetracetate in a mixture of anhydrous acetic acid and acetic anhydrides and the product chromatographed. Product isolated and identified included allopregnane- 3:21-diacetoxy-20-one, and allopregnane-3:17: 21-triacetoxy-20-one. The latter product on treatment with potassium bicarbonate in methanol yielded a product in which the 21- acetyl group was saponified. Oxidation of this saponification product with periodic acid and further saponification yielded 3 (B) : 17 (B)- dioxy-etioallocholanic acid; (3) #<SP>3</SP>-pregnene- 3-acetoxy-20-one is treated with lead tetracetate in a mixture of anhydrous acetic acid and acetic anhydride under the same conditions as in example (1), and the resulting product chromatographed to give #<SP>5</SP>-pregnene-3:21- acetoxy-20-one and #<SP>5</SP>-pregnene-3:17:21-triacetoxy-20-one. Specifications 500,767, 502,474 and 524,006, are referred to.

Abstract: 448,162. Knitting-machines. HEMPHILI, CO., Central Falls, Rhode Island, U.S.A. (Assignees of Lawson, R. H. ; 55, Cooke Street, Pawtucket, and Cloutier, A. N. ; 497, Broad Street, Lonsdale, both in Rhode Island, U.S.A.) Aug. 9, 1935, No. 22547. Convention date, Aug. 9, 1934. [Class 74 (ii)] In order that the toe or other parts of stockings &c. may be narrowed and widened less abruptly than usual, needles which are moved from action during narrowing, or are restored to action during widening, are temporarily returned to action during said narrowing and /or withdrawn from action during widening. In the apparatus shown the widening picks 7 are controlled during the knitting of the stocking by a cam 47 through a lever 44, rod 48, lever 50 and push rod 9. During the knitting of the toe the end 46 of the lever 44 is in the cam recess 111 and the widening picks 7 are controlled by a separate pattern chain 15 provided with links 95 which act on the picks through the rod 48, a link 54, and a lever 59, 63. This chain 15 is operated through a ratchet wheel 18 and two pawls 20, 38 oscillated by a connection 24 from the lever which reciprocates the needle cylinder during knitting of the toe. Until toe knitting commences the pawl 38 is held out of action by a rod 83, 66 and the pawl 20 by a lug 93 on the chain 15. When toe knitting is to commence, i.e. when the lever end 46 drops into the cam recess 111, the end 77 of a lever 73 is raised by the cam 78 and the rod 83 and pawl 38 are lowered. After the wheel 18 has been moved a few teeth by the pawl 38 the cam 78 can lift the pawl 38 out of action, the pawl 20 then continuing to drive the wheel 18 until the knitting of the toe part is completed when the lug 93 will again lift the pawl 20 out of action. During widening, the recesses 100 between the links 98, 99 allow the widening picks to be temporarily withdrawn at intervals. The links 95 are stepped at 951 to move the picks in stages and thus prevent damage to needle &c. butts. The arrangement of links shown in Fig. 11 will give a toe. Another arrangement will give a toe as shown in Fig. 15. Instead of controlling only the widening picks the narrowing picks or both the narrowing and the widening picks may be controlled. Specification 20101/09, [Class 74 (ii)], is referred to.

Filed: 1969-05-05
Abstract: 1276668 Control systems for resistance welding apparatus CONTINENTAL CAN CO Inc 5 May 1969 [3 May 1968 22833/69 Heading H2H [Also in Division H3] An electrical resistance welding apparatus comprises co-operating welding electrodes to which is connected a D.C. source of energy, means being provided whereby the polarity of the electrodes is reversed so as to cause the current flowing through the electrodes to decrease suddenly together with further means to reduce the flow of welding current thus to stop a welding operation at a precise instant. A resistance welding apparatus 21, used in the seam welding operations for cans, is supplied from a three phase source 11 by way of a transformer 13 and a rectifier 15. The flow of welding current through the electrodes is started and stopped or rÚdueed by means of a circuit 23 in shunt with the electrodes according to the presence or absence of a can at the electrodes. When a can appears at the welding electrodes its presence is sensed by a phototransistor in a start weld circuit 25 to produce a signal which is eventually applied to the shunting circuit 23 by way' of a monostable multivibrator circuit 27 arid a current gain circuit 31. This signal causes the circuit 23 to became non-conductive whereupon normal welding current flows in the welding electrodes. When the can seam has been completed the absence of the can at the electrodes is sensed by a phototransistor in a stop weld circuit 35 to produce a signal which is applied to the circuit 23 by way of a circuit 32. This signal causes the circuit 23 initially to reverse the polarity of the electrodes so as to produce a sudden drop in the electrode current flow and then to become conductive so as either to reduce the electrode current flow or interrupt it, in either case terminating the welding operation. The stop signal from the circuit 35 is also fed to the multivibrator 27 as a reset signal thereby to terminate the welding process. The multivibrator also has a built in timer device so as to stop the welding operation after a preset time if no signal appears from the stop weld circuit 35. A circuit 36 is provided to assist the circuit 23 to resume its non-conductive state when a signal appears from the start weld circuit 25. Furthermore a double pulse circuit 28 may be utilized by means of a switch 30 in order to ensure that the current flowing through the welding electrodes at the beginning of each welding operation is of the same amplitude as that at the termination of the preceding welding operation.
