Abstract: 283,198. Budd Manufacturing Co., E. G., (Assignees of Ledwinka, J.). Jan. 8, 1927, [Convention date]. Doors for passenger vehicles.-In an all-metal door for vehicles of the kind having a window opening in its upper portion and comprising inner and outer panels and glass run channels, the inner and outer panels are constituted by one-piece stampings extending completely around the window opening and each provided with a beading or garnish so as to form a finish extending entirely around the window opening on both sides of the door. The outer panel 20 consists of a substantially flat plate which, at the window opening 22, is formed with an inward sweeping curve 23, Figs. 6 and 8, broken by a shallow depression 24 and terminating in a flange 25 around which one portion of the glass rim channel is crimped. The inner panel 26 is a deep drawn stamping forming a vertical hinge rail 28, Fig. 6, of Z-section and a vertical jamb rail 29, 32, 30, Fig. 8, of double Z-section, the stamping being bent around the window opening in a smoothly rounded bend 33 terminating in a flange 34 around which another portion of the glass run channel is crimped. At its peripheral edges 21 the outer panel 20 is crimped over the outer flanges 21 of the inner panel so as to form the door overlap. The glass run frame is built up as a unit, Fig. 4, comprising on one side a channel 39 adapted to be spot welded to the web 28, Fig. 6, and at the. opposite side a channel 40 built up of two stampings 52, 52<1> Fig. 8, welded to each other and to the intermediate part 32 of the jamb rail. These glass run channels 39, 40 are connected at the upper part of the window opening by a pair of cross members 41 welded to the top rail 34<1>, Fig. 5, and crimped at 50 over the curved or beaded portions 23, 33, and at the lower part of the window opening by a pair of cross members 42 crimped at 51 over the edges of the inner and outer panels.

Title: Improvements in or relating to the formation of coherent metal layers on granular surfaces
Inventor: BOS CORNELIS
IPC: H01J29/28
Filed: 1952-12-18
Abstract: A method of forming a coherent metal layer on a granular surface, for example an aluminium layer on the luminescent screen of a cathode-ray tube, comprises depositing a gelatinous material on the surface, drying the material to cause shrinkage to produce a coherent film supported on the peaks of the surface, applying a coherent metallic layer to the film, and removing the film.  The film can be formed by wetting the granular surface with one of two reacting substances, e.g. ammonium alginate, and applying to the surface the other of the reacting substances, e.g. zinc nitrate, to cause deposition of a gelatinous precipitate, e.g. zinc alginate, on the surface.  Other soluble inorganic or organic alginates may be employed and calcium, barium or strontium nitrate or a gaseous medium used as a precipitant.  The metallic layer, which may be of aluminium, can be deposited by a vaporizing method and the gelatinous film removed by heating to about 450 DEG  C.ALSO:A method of forming a coherent metallic layer on a granular surface, for example an aluminium layer on the luminescent screen of a cathode ray tube, comprises depositing a gelatinous material on the surface, drying the material to cause shrinkage to produce a coherent film supported on the peaks of the surface, applying a coherent metallic layer to the film and removing the film.

Abstract: 1526915 Automatic exchange systems; call barring SIEMENS AG 1 Aug 1977 [2 Aug 1976] 32175/77 Heading H4K In a call barring arrangement, e.g. for a PBX, an exchange line set seized for the call prevents the transmission, e.g. to an external exchange of at least the first dialled digit until it has been stored and evaluated for admissibility. In the embodiment, which deals with only the first dialled digit, when an exchange line set AUE is seized for a call from a subscriber T, transmission of dialled digits to a main exchange is prevented by relays U, U, through contact 24; a hunting device WS-S finds a free store WS and converts it to set AUE through a coupler SK-K controlled by relays U, U,. The dialled digit is stored in store SW and evaluated for admissibility by an evaluator BW. If the digit is valid pulses representing said digit are sent to the main exchange via an auxiliary winding LW in the set AUE, if not the call is abandoned. While the stored digit is transmitted a tone is sent to the subscriber to prevent further dialling. Three digits, or the complete number may be similarly validated.

Abstract: 533,905. Aerials ; inductances. PHILIPS LAMPS, Ltd. Dec. 14, 1939, No. 32248. Convention date, Dec. 17, 1938. [Class 40 (v)] [Also in Group XXXV] One or more of the high-potential turns of a screened inductance coil, particularly a frame aerial for short-wave working, are located at the centre of the screening tube, whilst successive turns are arranged on equipotential surfaces of the electrostatic field created between the highestpotential winding and the earthed screen. The object is to minimise the inherent capacity of the system as a whole. As shown in Fig. 1, the highest-potential winding 1 is located in the centre of the screening tube 11, the winding 2 next in series is laid , adjacent to and on one side of the first, whilst the earthed winding 3 is placed on the opposite side near the inner surface of the tube. In Fig. 3, which is a section through the tube, the spacing between successive windings 1 ... 8 is graduated so that the average potential of each corresponds to equipotential surfaces in the internal field. In Fig. 6 the first three windings 1, 2, 3 are located at the centre, whilst later windings 4 ... 8 are grouped on equipotential surfaces as shown by the circles, the last three windings 7, 8, 9 also being of larger diameter than the others, so as to spread any deformation of the field over as large a surface as possible.

Title: A method of manufacturing valuable rubber mixtures
IPC: C08K3/013
Filed: 1949-12-16
Abstract: Sublimed silica, which may be used in rubber compositions, (see Group V), is obtained by heating sand in an electric arc to a temperature of over 2230 DEG C in such a manner that radiant heat of the arc causes the surface layer of the silica to vaporize, and condensing the gas on cooling coils or a rotary cooled drum.  Slow condensation gives particles of the crystalline form of silica and rapid condensation gives spherical particles.ALSO:Rubber compositions comprise as filler, an inorganic sublimate which is compatible with the rubber and other ingredients of the mixture.  Specified sublimates are those of aluminium oxide and silica, the latter preferably being obtained by heating sand in an electric arc to a temperature of 2230 DEG C and then depositing the gases formed on a cold surface such as cooling coils or a rotary cooling drum.  The silica thus obtained is vulcanized in a mixture consisting of smoked sheets, sulphur, benzothiazyl disulphide, diphenyl guanidine and zinc oxide.  The properties of the sublimates can be modified by varying the rate of condensation.

Filed: 1949-12-21
Abstract: 663,352. Electric bells.. WESTERN ELECTRIC CO., Inc. Dec. 21, 1949. [Dec. 22, 1948] No. 32717/49. Class 13. [Also in Group XXXV] A telephone ringer of small size comprises a U-shaped laminated silicon steel electromagnet with a single operating coil 111 and a short bartype polarizing permanent magnet 119 mounted at right angles to the longitudinal axis of the electromagnet core limbs. In the magnetic circuit Fig. 8, broken lines indicate the flux set up by operating half cycles of ringing current and continuous lines the biassing flux set up by the permanent magnet. When ringing current traverses the coil 111 the first half cycle produces a decrease of flux in the core of coil 111 and disequilibrium of fluxes in parts a, b of the operating air gap so that armature 123 moves clockwise against the tension of spring 132 until the right-hand stop engages the pole face 116 and the clapper 130 strikes one of the gongs 149. During the next half cycle of ringing current the disequilibrium of fluxes in air gap sections a, b is reversed and augments the action of spring 132 in moving the armature counterclockwise until its left-hand stop abuts pole face 136 and clapper 130 strikes the other gong. The armature 123 is freely mounted on a pivot pin 122 located in alignment with the polar axes of the permanent magnet 119 so that the latter will have negligible biasing effect through the adjacent air gap c. A magnetic shunt 138 is provided and is designed to operate in an unsaturated condition at low ringing voltages and in a saturated condition at high ringing voltages. The clapper 130 is yoke shaped and the two gongs 149 are mounted with their axes at 45 degrees to the plane of the electromagnet and clapper rod 129.
