Abstract: 249,377. Lassen, F. June 23, 1925. Bodies; bottoms.-In pasteurizing a liquid, e.g. beer, containing gases evolved on heating but in which the gas content should be the same before and after pasteurization, the, liquid is heated in containers with expansible walls, the containers before the pasteurization being practically completely filled with the liquid, and, after pasteurization and subsequent cooling, being exposed to external pressure positively applied to bring their volume back to its original value. In the form described, the containers a are made of metal, their bottoms b<1> being made of softer or thinner material than the bodies, e.g. the containers are of hard and their bottoms of soft aluminium, the bottom b' being normally concave in shape but assuming a convex shape when the containers are heated. The containers, which are closed by screw caps g, may be placed on sockets c in compartments in a tank h into which hot water for pasteurizing or cold water for cooling may be led. After pasteurizing and cooling the containers are restored to their original form by a lever e slidingly pivoted on a. bar d fixed on the tank, the lever being brought opposite the bottle and pressed against its cap g either by hand or mechanically, the bottom b' of the container being then restored to its concave form by the socket c. Other parts than the bottom of the container may be made expansible, and the containers may be exposed to hydraulic pressure to restore them to the original shape.

Title: High temperature magnetic cores and process for producing the same
IPC: H01F41/02
Filed: 1964-04-20
Abstract: <PICT:1005627/C1/1> A sheet of ferromagnetic material 30 is coated with glass having a temperature/viscosity characteristic such that at the annealing temperature of the ferromagnetic material the glass coating is sufficiently viscous to bond with a similar coating on an adjacent sheet of material, but will not run off the surface of the sheet. The magnetic sheet is run through a number of tanks (Fig. 1, not shown) in which is carried out successively degreasing, rinsing, pickling, rinsing, electro-plating with a thin coating of nickel, rinsing and neutralizing of any acids picked up by the sheet.  It is then run through a coating tank 42 (Fig. 2) containing a suspension of vitreous particles in a vehicle such as amyl acetate or isopropyl alcohol, the coating is dried by infra-red lamps 44 and is fused to form a thin glass layer on the strip in tube furnace 46. The glass coated sheet is made into magnetic cores by winding it or stacking stampings made from it and when the cores are annealed to remove straws the glass coatings bond together or, if the sheet is coated on one side only, bonds with the adjacent uncoated sheet.  Ranges of percentages of materials which may be used for making the glass used as the coating material are as follows:  SiO2 36.00-54.65, B2O3 5.05-18.00, Al2O3 2.00-7.35, Na2O 3.65-18.00, K2O 7.00-30.45, CaO 0.00-10.00, Ca F2 0.00-5.00, BaO 0.00-20.90, ZnO 0.00-4.05, ZrO2 0.00-1.35, MnO2 0.50-1.00, NiO 0.50-1.00, CoO 0.50-1.50.  In these proportions boron oxide can be reduced to 2% or less.  Sodium oxide can replace the potassium oxide.  Manganese, nickel and cobalt oxides can be left out.  Glasses containing up to 15% ZrO2 and 15% TiO2 can also be made.

Title: Improvements in or relating to electromagnetic relays
IPC: H01H51/01
Filed: 1938-05-31
Abstract: 515,529. Electromagnetic relays. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., RAYNER, T. R., and MARING, A. O. May 31, 1938, No. 16308. [Class 38 (v)] The armature 12, 22, of a polarized relay is moved to one position by current flowing through the operating coil 17 in one direction and is moved to its other position by current through the coil 17 in the other direction, and is retained in either position by the magnetic action of a permanent magnet 13. The axis of the magnet 13 is parallel to the core 30 of the electromagnet 17 and yokes 10, 14 are arranged as shown. The armature is pivoted at its centre and has one arm 12 adapted to be attracted to a pole 25 and another arm 22 adapted to be attracted to the core 30 of the electromagnet. When current is passed through the magnet 17 to magnetize it in the same direction as the magnet 13, the pull on the arm 12 will be greater than on the arm 22 and the armature will move and operate the springset 11. After operation, current in the reverse direction will reduce the flux through 12 and increase the flux through 22 causing a restoration of the armature to its normal position.

Title: Improvements in apparatus for launching rocket-type ammunition
IPC: F41A9/32
Filed: 1947-06-23
Abstract: 632,599. Rocket-launching guns. ZBROJOVKA BRNO, NARODNI PODNIK. June 23, 1947, No. 16588. Convention date, July 16, 1946. [Classes 92 (i) and 92 (ii)] Rocket-type projectiles are fed one by one to a discharge guide and are automatically fired when reaching the firing position, the feed means being drivably connected to an operating member located in the path of the gases discharged from the projectiles at the time of firing, so that the feed movements of said feed means are transmitted to it by the operating member. In the construction shown, the gases of discharge from the rocket 7 impinge on vanes formed on the inner surface of the operating member 3, which is rotatably mounted on the cylindrical extension 4 of the discharge guide 1. The rotary motion of the member 3 is transmitted to a member 6, which drives the belt feeding the rockets, through a slipping clutch 5. Thus, upon firing one rocket the belt is moved and when the next rocket reaches the firing position, both it and the belt are retained by a pivoted lever 12. This lever is moved slightly by the rocket against the action of a spring 15, such movement closing a switch 13, 14, in the firing circuit. The launching of the rocket enables the belt to move to the next position, the chambers 11 of the belt being slotted so that they can pass the lever 12. In a modification the gases impinge on a propeller geared to the clutch 5, and in another modification they impinge on blades of a member forming an element of a clutch. In another construction, the chambers 11 are rigidly interconnected and pass between straight guides to the firing position. Specification 596,288 is referred to.

Abstract: 705,547. Supply systems depending on the use of two or more sources; smoothing. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd., and WALKER, A. H. B. May 29, 1953 [July 8, 1952], No. 17146/52. Classes 38 (2) and 38 (4) D.C. load terminals 20, normally supplied from an A.C. source 1, 1 through transformer 3 and main rectifier 15, are associated with a standby battery 19 comprising a portion 19b having a normal voltage slightly below that at the load terminals across which it is connected through normally closed contacts 18 and a half wave rectifier 17 which allows trickle charging of the portion 19b in the high resistance direction of the rectifier. Another portion 19a of the battery has sufficient cells to bring the total voltage of the battery up to that necessary to maintain the load voltage when the battery takes over the supply upon mains failure. When this occurs contacts 16 automatically close and the whole battery is thereby connected across the load terminals. The output from the main source is smoothed by inductance-capacity stages 21, 23 and 22, 24, the condenser 24 of the last stage being connected across the rectifier 17, whereby a condenser of relatively low working voltage may be employed, which condenser also temporarily boosts the voltage of the battery portion 19b (and so helps to maintain the load voltage) during the short period between mains failure and closure of contacts 16. An auxiliary rectifier 13 in series with the main rectifier 15 and having saturable reactor control 7, 8, 11 responsive to battery voltage maintains the portions 19a, 19b on trickle charge. Contacts 18 are opened when charging at full-rate is necessary. Automatic control of the output voltage of the main source is by a further saturable reactor 9, 10, 12 which governs the voltage output of a boosting rectifier 14 in series with the main rectifier 15.
