Title: Processes for treating and stabilizing wheat germ
IPC: A23L7/152
Filed: 1934-11-06
Abstract: Wheat germ is treated to stabilize it against rancidity and to improve its keeping qualities by grinding it to about the fineness of flour, mixing with it prior or subsequent to or during the grinding common salt to absorb moisture and inhibit too rapid a diastatic action of yeast in baking, and then adding an inert non-fatty filler such as potato flour, rice flour, rice polishings or corn flour.  The salt added may be 5-8 per cent by weight of the wheat germ and the potato flour 15-20 per cent.  The product is dried before or after addition of the filler by heating without free access of air or in a current of carbon dioxide, nitrogen or other inert gas, e.g. by heating to 200-225 DEG  F., preferably 212 DEG  F., for 20 minutes in a closed oven.  The product may finally, preferably while still warm, be enclosed in containers which are airtight or proof against free air circulation and which may be filled with carbon dioxide, nitrogen or other inert gas.  The Specification as open to inspection under Sect. 91 comprises also the use in place of common salt of other substances having the required characteristics.  This subject-matter does not appear in the Specification as accepted.
Patent GB-951227-A (GB)
Title: Improvements in or relating to nuclear reactors
Inventor: ROCHE ROLAND
IPC: G21C13/087
Filed: 1961-09-06
Abstract: 951,227. Controlling nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 6, 1961 [Sept. 6, 1960], No. 31991/61. Heading G6C. A container 2 of a nuclear reactor contains, internally and at its top, a bell 3 immersed in a liquid moderator at least as far as the minimum level reached by the moderator, and a gas pressure is set up beneath the bell 3 and above the free surface of the moderator so that the liquid entirely fills the space between the container 2 and the bell 3,the pressure being variable in order to adjust the surface level, and the shape of the bell 3 allows between it and the surface an expansion space for the liquid moderator. The moderator, which cools the container 2, is then circulated through the pipe 4 to the heat exchanger 6 for cooling. The pressure regulating system comprises a fan 10, valves 11 and 12, and a pipe 13 which communicates with the inside of the bell 3. The valves are connected to an expansion and charging receiver 16, and the difference in level between the liquid in the receiver 16 and container 2 corresponds to the pressure drop in the valve 12; thus adjustment of the valve 12 alters the level of the moderator and so the reactivity. Should the fan 10 fail the bell would become filled with moderator and the reactor might be caused to run away, but this is avoided by enabling the liquid to rise in the tube 19 and be discharged to the tank 20a, thus lowering the liquid level on the container 2. The gas pressure within the container is limited by a calibrated valve 8 opening into a discharge chimney 9. Fluid-tight tubes 21 and 22 are fitted facing one another in the container 2 and bell 3 to enable control rods to pass. In another embodiment (Fig. 2, not shown) tubes 1 which are above the liquid surface are cooled by surrounding them with individual bells connected to the main bell via pipes which circulate liquid over the tubes. A transparent tube 17 enables the moderator level inside the reactor to be followed visually.

Abstract: 810,984. Fluid-actuated valves. RANCO Inc. Nov. 10, 1955 [Nov. 29, 1954; Dec. 6, 1954], No. 32174/55. Class 135. A valve mechanism comprises a valve chamber 13 having at least two spaced outlets 25, 26 and spaced inlets 17, 18 communicating with the outlets and selectively connectible to high pressure in a fluid flow system according to the position of valve means 22, and a piston 27 movable in opposite directions, according to which inlet is open, to close one of the outlets and open the other. The valve mechanism is shown in a refrigerating system and the valve 22 is operated by a solenoid 21 controlled by a timer mechanism to initiate defrosting. On opening an inlet high pressure acts on the annular area at one end of the piston so as to move the piston to open the outlet communicating with the open inlet and close the opposite outlet. The high pressure at 26 then acts on one of two pistons 48, 47 attached to two connected shuttle lift valves 46, 45 whereby the shuttle valve moves to direct the high pressure to a pipe 51 and a pipe 50 is connected to a pipe 9 on the low pressure side of a compressor. In a second embodiment the piston valve 22 is replaced by a shuttle lift valve. Pipes 50, 51 respectively connect to a condenser and evaporator connected in series.

Abstract: 1,114,153. R.F. couplings. BRITISH BROADCASTING CORPORATION. 22 July, 1965 [7 Aug., 1964], No. 32288/64. Heading H4A. [Also in Division H1] Two different radio-frequency bands applied at ports A and C, respectively, are fed to a common load B, e.g. an aerial, by means of a network of transmission lines having four ports A, B, C, D, the port D being connected to a dissipative load. The network may be in the form of a ring having the electrical dimensions indicated. Substantially the whole input energy is coupled to the port B if X approximates to m x 90 at the mid-band frequency of the input at A and to n x 90 at the mid-band frequency of the input at C, where m is an even integer and n is an odd integer. The dimensions of the ring are, in fact, such that the signals are in phase at the port B and in antiphase at the port D. Four channels may be combined by using two of the networks to combine the signals in pairs and a third to combine the combined pairs.

Title: Improvements in and connected with the refining of lead
IPC: C22B13/06
Filed: 1933-11-20
Abstract: 417,286. Refining lead. WILLIAMS, G. K., 174, The Terrace, Port Pirie, South Australia. Nov. 20, 1933, No. 32315. Convention date, Nov. 20, 1932. [Class 82 (i).] In a continuous or substantially continuous process for refining lead, molten lead containing one or more readily-oxidisable alloying metals such as zinc, antimony, arsenic, and tin, passes continuously into a treating chamber, and lead low in such metals is discharged continuously therefrom, the lead during its passage through the chamber being subjected to oxidation under suitable conditions of temperature whereby oxides of lead and of the alloying metals separate in the form of liquid slag which exists above the lead and is continuously or intermittently discharged from the chamber. The process may be carried out in a reverberatory furnace, which is provided with ordinary means for the access of air thereto, the lead being added at 10 and escaping at 11, whilst the slag escapes at 12. The molten metal may be agitated by air or other gas introduced below the surface by pipes 14, this agitation being preferably sufficient to cause the formation of a layer of litharge on the walls and roof of the furnace and also to produce uniform conditions of temperature and composition throughout the slag and throughout the lead, the jets being so disposed as to provide quiescent conditions near the discharge orifices. The air so introduced may assist in the required oxidation, which may be such as to maintain the reaction temperature, preferably 800‹ C. without the use of extraneous heating means. The process as described may be applied to the softening of lead or to the process of removing zinc from lead or both more particularly when a process of continuous desilverizing such as that described in Specification 267,104, [Class 82 (i)], is employed. When the process is employed for the removal of zinc from lead, the furnace may be heated by oil burners and a suitable reagent is supplied to the bath either separately from, or in conjunction with, the lead to be refined. This reagent may be arsenic or antimony, or both, preferably in the form of antimony dross from the softening process, or antimony slag or hard lead produced from the said antimony dross, or zinc-antimony lead produced from the zinc-antimony dross from a previous zinc-refining operation. The antimony so supplied amounts to 0À2-0À4 per cent of the lead supplied during the same period.

Abstract: 1,001,805. Disc brakes. GIRLING Ltd. July 31, 1964 [Aug. 16, 1963], No. 32453/63. Heading F2E. A disc brake of the kind in which relatively stationary and rotatable surfaces are frictionally engaged on axial separation of two co-operating pressure plates 10, 11 by balls working in inclined ramps of adjacent surfaces of the plates, is characterized in that the balls 18 are located in angularly spaced, axial grooves 19 of semicircular cross-section formed in the inner surface of the concentric housing 14 and engage in oppositely inclined, arcuate crosssection pockets 21, 22 at the peripheral edges of the plates' adjacent faces, each of the pockets progressively varying in depth in an axial direction and being located on the same pitch circle. The axial deeper end of each pocket is part spherical and of a radius equal to that of the ball as illustrated in Fig. 3. On induced relative angular movement of the plates 10, 11 by pull-rod 24 through linkages 26, 25, the balls will lock in the spherical pocket ends of one plate, so arresting its angular movement, and ride up the inclined pocket faces of the other plate to urge the plates apart thereby forcing rings of friction material 15, which are carried by rotatable discs 16 slidably mounted on a splined shaft (not shown), to engage the fixed housing 14 and complementary cover plate (not shown). The grooves 19 permit axial movement of the balls. Springs 23 retract the plates when the brake is released. The angular movement of the plates may be induced by other means such as a shaft-mounted cam operating between adjacent radial lugs on the plates.
