Title: Improvements in tubulous heat exchangers
IPC: F28F13/06
Filed: 1962-11-12
Abstract: 1,017,388. Fuel elements. BABCOCK & WILCOX Ltd. Nov. 12, 1962 [Nov. 13, 1961], No. 42651/62. Heading G6C. [Also in Division F4] Fluid, e.g. a gas, passing through a duct 32 receives heat from a tube 31 comprising a nuclear fuel element. The fluid flows to the duct by way of inlet tubes 34 and longitudinally extending channels 35 (see also Fig. 7, not shown) each having an open side sealed against a layer 33 of sintered metal or other porous material which covers the tube 31. The fluid can therefore enter the duct 32 only by way of the capillary channels in the porous layer 33 (see arrows) and is heated as it passes through these channels.

Abstract: 1,123,261. Cooling synchronous dynamoelectric machines. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM). 7 Oct., 1965 [7 Oct., 1964], No. 42674/65. Heading H2A. In a synchronous dynamo-electric machine e.g. turbo-alternator comprising a rotor 2 having a field winding fed electrically via current rectifiers 16 from the armature winding 15 of an alternator exciter rotor 14 mounted on the shaft of the rotor 2, both windings are of a metal which is as pure as possible and together with the rectifiers are cooled by a cryogenic fluid e.g. liquid hydrogen, neon or nitrogen conducted to the field winding by conduits 11, 12. The rectifiers 16 may be vacuum tubes, super-conductive, or semiconductors in diode, controlled, transistor, or field effect form; or to effect rapid de-excitation they may be thyratrons. The fluid enters a labyrinth sealed housing 18 detailed in Fig. 5, and flows through a shaft annular channel 27, the rectifier compartment 17, the winding 15 and possibly additional tubes in the rotor 14, back to the channel 27, and along to the conduit 11; hollow connections 34 electrically connect the winding 15 to the rectifiers 16, and hollow connections 36 from the rectifiers, through the rotor core, convey both the fluid and excitation current to the field winding. The fluid returns via a central channel 33.. The connections are also of metal similar to the windings, and connections and windings are covered by both electrical and heat insulation. The turboalternator stator winding 7 is directly cooled by water or oil, and the exciter and its rectifiers alternatively may be disposed between the rotor 2 and the shaft bearing 3.

Title: Improvements in or relating to ceramic seals and magnetic transducers employing same
IPC: H01F1/03
Filed: 1961-12-05
Abstract: A method of applying a vitreous seal as a spacer element in a gap of a ceramic body, in particular for forming a non-magnetic gap in a magnetic head assembly comprising a magnetic body of ferrite, comprises the steps of pulverizing and mixing a fluxing glass, a wetting glass and powdered ceramic material; applying the suspension to the ceramic body within the gap and firing the body at an elevated temperature to vitrify the seal material so that there is an interatomic exchange between the seal mixture and the ceramic body to form a microstructural transistion layer therebetween. The melting-point of the spacer material is less than that of the ceramic body but the expansion coefficients are close.  All the ingredients are finely ground before mixing.  The preferred mixture has, in percentages by weight, fluxing glass 35, wetting glass 40 and ceramic material 25.  The fluxing glass may consist of, in molecular percentages, CaO 0.20, K2O 0.10, Na2O 0.20, Le2O 0.50, Al2O3 0.11, B2O3 0.04, SiO2 1.45, and the wetting glass in weight percentages, PbO 50, Fe2O3 20, SiO2 10, ZnO 5 and B2O3 15.

[Also in Division B8] In the thawing of a block of frozen fish or other sea food the block is submerged in water at least to the level of its upper surface and whiles submerged is subjected to dielectric heating in a radio frequency electric field. Containers filled with blocks of the frozen edible matter may be passed on a conveyer band at a speed of e.g. 2 or 3 inches per minute, continuously or intermittently, firstly under a source of water and then through a series of, for example, three dielectric heating ovens which are supplied with radio frequency energy at a frequency of between 36 and 40 mc/s and are separated from each other by interference attenuation ducts. The containers of wood or plastic may consist of trays 15 having lateral extensions 17 from their upper edges which overlap adjacent trays when these are arranged end to end, the extensions thus serving to hold the lid 16 of the adjacent tray and its content of frozen matter below the level of the tops of the sides of the trays; the lid may be in the form of a lattice or may have strips or fingers in an open-work construction extending over the fish. In the absence of the extensions referred to, plastic straps may be used to secured the blocks against floating. The method is stated to be particularly applicable to cod and like white fish, though equally satisfactory for fatty fish such as herring.

Abstract: 944,675. Fluid-pressure servomotor control systems. OILGEAR CO. Dec. 19, 1961 [Jan. 4, 1961], No. 45425/61. Heading G3P. [Also in Divisions B5 and G1] A hydraulic press for forming resilient and yielding materials consists of a ram 6 supplied with hydraulic fluid by a variable displacement pump 8 and provided with means for varying the pressure applied by the ram in accordance with the displacement thereof. As shown, the ram is single-acting,being returned by gravity, but it may  be double-acting. The initial advance of the movable platen 3 is performed by auxiliary cylinders (not shown) until a switch, responsive to a predetermined pressure in the auxiliary cylinders, or a switch LS-1, actuated by an abutment 78 movable with the ram 6, energizes an electric circuit (see Division G1) whereby the output from a displacement transformer LVDT-1 connected with the displacement varying means 9 of the pump is compared with the output from a preset potentiometer (not shown) and the difference signal passed through an amplifier to an electric torque motor 61 which actuates a valve 52 controlling a spring-centred piston 44 which actuates a piston valve 38 working in a movable seat 29 connected to a servopiston 27 controlled by the valve 38, whereby the pump displacement is adjusted to a value set by the preset potentiometer. When the ram 6 has moved sufficiently to bring an abutment 79 into contact with a switch LS-2, or when the pressure of the supply to the ram has reached a value to operate a switch PS-2, the electrical output from a pressure transformer LVDT-3 is compared with that from a transformer LVDT-2 which is actuated by an adjustable cam 67 moved by the ram so that the servopiston 27 is controlled to cause the pressure applied to the ram to diminish in proportion to the displacement of the ram. The ram continues to move until an abutment 80 engages a switch LS-3, or the pressure has fallen to a value at which a switch PS-3 is operated, whereupon the output from LVDT-2 is compared with a preset potentiometer to control the servopiston 27 to maintain the ram in a fixed position, until a time switch causes the pump displacement to be reversed so that the ram is exhausted. The pump is set to zero displacement on the detection by a switch PS-4 of a predetermined low pressure.
