Title: Air leak detector
IPC: H01M50/112
Filed: 1973-02-26
Abstract: 1400694 Leak testing; measuring fluid-flow GOULD Inc 26 Feb 1973 [15 March 1972] 9396/73 Headings G1R and G1S [Also in Division H1] To test a container such as a battery container 11 for small leaks a source 12 of air under pressure is connected to the container via a pressure regulator 15 and an open/close valve 32, the valve 32 being by-passed by an open/close valve 16 and an air-flow meter 17 including a ball 18 which is displaceable in a transparent frusto-conical tube 22 from a zero position in response to air-flow therethrough, the presence of the ball in a non-zero position being detectable e.g. by a photo-electric system. In use, the valves 16 and 32, controlled by solenoids 19 and 33, are opened and air supplied to the container 11 to fully charge it to a test pressure at which point the ball 18 will be in its zero position if there is no leak. Valve 32 is then closed. If a leak in container 11 exists, the ball is displaced into a non-zero position by continued air-flow through valve 16 and the meter 17. Thus if valve 16 is subsequently closed and another solenoid 21 operated to close a detector circuit, the ball 18, in returning to its zero position, will cross the path between a lamp 26 and a photo-cell 27 and so trip a relay 28 for operating an alarm or automatic reject device. The solenoids 19, 21 and 33 may be operated by a series of switches either manually or automatically actuated.

Title: Improvements in couplings for rigidly joining two lengths of electrical wave-guide
IPC: H01P1/04
Filed: 1947-04-10
Abstract: 633,433. Wave-guides. GENERAL ELECTRIC CO., Ltd., HICKIN, E. M., and TEW, J. R. April 10, 1947, No. 9633. [Class 40 (v)] [Also in Group XXVIII] A coupling for two wave-guides comprises a body provided with a hole fitting closely round the ends of the guides which slide in, one from each end, and constrains the wave-guide ends into accurate alignment with each other or with a part of the body adapted to connect them electrically, and means for rigidly clamping the wave-guides to the body. As shown, two rectangular wave-guides, 1, 1<1> slide in a rectangular hole in a metal sleeve 2 screw-threaded on its outer surface. A metal collar 4 is secured to each wave-guide, and carries a rubber washer 5 round a shoulder on its inner face. Flanged sleeve nuts 6, 6<1> bear on the collars 4 through split washers 7 to press the wave-guide ends into abutment. Locking- nuts 8, 8<1> are provided on the sleeve 2. The collars 4 may be so positioned that the waveguide ends do not quite abut and an annular groove of depth equal to a half-wavelength on the inside of the sleeve provides an electrical connection between the guides. In a further modification, part of the hole in the sleeve is of reduced dimensions so as to form a short length of wave-guide against which the ends of the guide abut. The parts of the coupling, except the surface of the annular groove or of the smaller part of the hole may be of plastic material.

Title: Improvements in or relating to electromagnetic pick-ups

IPC: H04R11/08
Filed: 1948-04-08
Abstract: 651,432. Gramophone pick-ups. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 8, 1948, No. 9828. [Class 40 (iv)] In a moving armature pick-up the armature is supported by a shaft which is mounted for oscillatory movement about its axis and which carries at one end a stylus arm resilient in directions substantially parallel to the axis of the shaft but having substantial stiffness in directions at right-angles thereto. The pick-up comprises a rectangular bar magnet 1 (Fig. 1), with a pair of L-shaped polepieces 2, 3 denning an air gap in which the armature 5 is mounted. The armature 5 (Fig. 4), is a lateral extension projecting from the shaft 8 which is supported in a vertical position by being clamped between a pair of metal plates 9, 10 (Figs. 1, 3), secured to the polepieces by screws 11, the pick-up coil 12 being clamped between the plate 9 and the polepieces. The plate 10 has a groove to accommodate the shaft 8 which is of circular cross-section and the end portions of the shaft are covered by short lengths of rubber or like tubing 14 (Fig. 4), to enable oscillation of the shaft to take place under the control of a stylus arm 15 fixed to its lower end. This arm which is substantially co-planar with the armature consists of a length of leaf-spring and is resilient in directions substantially parallel to the axis of the shaft but has substantial stiffness in directions at right-angles thereto. The sleeves 14 provide restoring forces for the shaft but if desired an additional spring may be provided for this purpose. The base plate 6 (Figs. 1, 3), may be made of non-magnetic material and the coverplate 7 of magnetic material in order to shield the magnetic system from a turn-table. To prevent damage to the stylus should the pickup be dropped on to a record the stylus arm projects through an aperture 18 in a spring arm 19 (Figs. 1, 3), secured to the cover-plate 7.

Title: Process for improving the mechanical qualities of glass

Filed: 1952-04-18
Abstract: 774,673. Annealing glass. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.- GOBAIN, CHAUNY & CIREY. April 18, 1952 [April 21, 1951], No. 9860/52. Class 56 A process for improving the mechanical properties of glass, especially that of being easily cut without breakage, consists in modifying the magnitude and distribution of the permanent stresses in the glass by causing in the superficial layers slipping effects in a sense opposite to those which have occurred at the commencement of cooling when the glass molecules were capable of moving relatively to one another. As applied to the treatment of drawn sheet glass the process consists in bringing the glass to about 420C. and exposing it to an intense heat flux produced by a gas burner or by other means such as radiation or dielectric loss heating for about one and a half seconds, the flux being of the order of 20 calories per sq.cm. per second and being sufficiently intense to generate expansion stresses in the external layers of the glass and to cause slipping of these layers with respect to the more rigid internal layers. Thus a glass sheet. having a normal stress distribution as indicated in Fig. 1 -wherein tension ordinates are shown below and compression ordinates above the zero stress axis X-X<SP>1</SP> has a stress distribution after treatment as shown in Fig. 2, this attentuated stress distribution being the same as that produced by the conventional annealing treatment.

Title: Process for producing self-carrying ceramic body with complex structure and self-carrying ceramic body with complex structure
Inventor: NEWKIRK MARC S
IPC: C04B35/65
Filed: 1987-06-30
Abstract: A method for producing a self-supporting ceramic composite body having a negative pattern which inversely replicates the positive pattern of a parent metal precursor (2) having thereon a positive pattern section (4,6,8,9) which is emplaced in conforming engagement with a bed of conformable filler (14). The parent metal precursor (2), which also has a non-replicating section, is melted and reacted with an oxidant to form a polycrystalline oxidation reaction product which grows primarily only from the positive pattern section of the parent metal precursor (2) and through the filler (14). The molten parent metal is drawn through the growing polycrystalline material and oxidized at the interface between the oxidant and previously formed oxidation reaction product. The reaction is continued for sufficient time to at least partially embed the filler (14) within the oxidation reaction product and form the ceramic composite body containing a negative pattern which inversely replicates the positive pattern of the parent metal precursor (2).
