Abstract: 355,277. Absorbent dental rolls. LADD, J. W. B., Katonah, New York, U.S.A. April 16, 1930, No. 12065. [Class 81 (ii).] Apparatus for forming dental absorbent rolls from compressible sheet material, particularly rolls of the kind described in Specification 355,276, comprises two bodies having opposed friction surfaces, one of which is free to move towards and from the other and is advanced along it to encounter the edge of the sheet material and to roll it upon itself. Means to apply a coating of adhesive to the finished roll to serve as a binder may also be provided. Overlapping sheets of absorbent paper 15 and cottonwool 17 are placed on a roughened surface of a platen 19 and are engaged by the curved edge 21 of a member 20 which is advanced along the platen to pick up the edge of the sheet 15 and roll it backwards upon itself together with the sheet 17, which adheres thereto and forms the outer convolution of the finished roll. The member 20 is formed with rockers 26 so that its front portion exerts a pressure on the roll, which pressure may be regulated by adjustment of counterbalance weights 29. The required initial separation of the two friction surfaces is maintained by means of shoes 30, on the member 20, riding on guides 31. Stops are provided to limit the longitudinal movement of the member 20, which is provided also with handles 35, 36. The friction surfaces may be provided by facing the platen 19 and member 20 with sandpaper, or if these parts are made of metal, by knurling or grooving them. After complete formation of the roll the part 20 is lifted by the handle 36 and moved backwards, a portion of the platen is coated with starch paste by means of a roller 40, and an endless belt 42 running over pulleys 43, 44 on a counterbalanced pivoted frame 47 is brought down on to the roll and is operated by a crank handle 49 to pass the roll over the coated area so as to apply an outer binding coating to the roll which is then placed in an oven to dry the starch.

Title: Improvements in or relating to the production of glass-to-metal seals
IPC: C03C27/04
Filed: 1962-03-29
Abstract: <PICT:0989365/C1/1> <PICT:0989365/C1/2> A process for sealing glass to a ferrous alloy comprises selectively oxidizing the iron constituent in the surface of the alloy to form thereon the ferrosoferric oxide of iron (Fe3O4), placing the glass and alloy in contact and heating to a temperature sufficient to effect hermetic bonding. The alloy may be iron-nickel, or iron-cobalt-nickel, and the glass boro-silicate or soda-potash-lead.  The alloy may be selectively oxidized by immersion in a basic solution comprising the hydroxide of an alkali metal, e.g. sodium or potassium, and an oxidizing agent, e.g. sodium nitrite or nitrate. A preferred solution is prepared by dissolving a mixed salt 66% NaOH and 34% NaNO2 in distilled water to form a solution having a boiling point of 142 DEG C. at which temperature the alloy is treated.  In the transistor assembly 10 (Fig. 1) comprising an eyelet type stem assembly 11 an overlying encasing member 12 and a semi-conductive element 16, the stem eyelet 13 and the leads 15 made from nickel-cobalt-iron alloy, are cleared and treated as above to form a surface layer of Fe3O4 before being sealed into the glass insulating core 14. The glass-to-metal seal may be formed using the powdered glass compacting technique disclosed in Specification 863,022.  In a continuous process for selectively oxidizing the surface of a ferrous alloy wire, the wire 151 (Fig. 3) is run off spool 32 into tank 33 containing the oxidizing solution where the black iron oxide layer is formed on the wire.  On emergence from the tank the wire is washed in tube 44 and dried by infra-red lamps 47 and 48, then collected on spool 35.  Before the oxidation treatment the wire may be thoroughly cleaned by known degreasing and pickling processes.

According to examples (1) sulphur black obtained by sulphurizing dinitro-phenol is dried in suspension with sodium sulphide and preserver's syrup as binder; (2) Sulphur navy blue obtained by sulphurizing the indophenol from o-toluidine and p-aminophenol is dried as above with molasses as binder; (3) sulphur brown, obtained by sulphurizing m-toluylenediamine is dried in presence of preserver's syrup; (4) Sulphur brilliant green obtained by sulphurizing the indophenol from 1-phenylaminon-naphthol-8-sulphonic acid and p-aminophenol is dried with molasses.  The drying of the sodium sulphide suspension containing the binder is performed in the above examples on an atmospheric drum dryer, but other known methods of drying may be employed.  Other binders specified comprise water-soluble neutral, non-crystalline organic materials such as cane-sugar, corn syrup, dextrine and cellulose glycollate.  The Specification as open to inspection under Sect. 91 comprises also examples of the drying of the following sulphur dye in presence of sodium sulphide, but without a binder:--sulphurized dinitrophenol, precipitated by various methods in presence of additional sodium bisulphite and thiosulphate in some cases.

Abstract: 5 91,445. Metal-vapour discharge apparatus; thermionic relays. FERRANTI, Ltd., ATKINSON, L., and CHILCOT, A. L. July 31, 1943, No. 12444. [Classes 39 (i) and 40 (v)] An impulse-actuated electronic relay tube comprises a mercury cathode 5, Fig. 2, coated on its surface with insulating granutated substances 29, e.g., quartz, glass, ceramics, &c., and a trigger electrode 8 comprising a cold conducting member disposed in proximity to the cathode. The trigger electrode is in the form of a ring or otherwise shaped to provide a free passage of the discharge to the anode 1 ; the walls of the envelope, which may be of glass or metal, have a coating of a mercury-wetting material. The application to high-speed photographing of a bullet in flight is described. The relay 2, Fig. 1, is in circuit with a flash lamp 3, and an energizing source comprising a condenser 4 and charging source 6, 7. The means for applying the triggering voltage to the electrode 8 consists of a thermionic oscillating circuit, comprising the screen grid valve 11, the output of which includes the tuned circuit 12, 13, and is connected to the trigger electrode through an inductance 9. The control grid 15 of the valve is negatively biassed to suppress oscillations by a source 22, which is shunted by two metal foils 20, 21, normally insulated. The passage of a bullet through the foils short circuits the source 22 and removes the bias potential from the grid. The potential impulse thus applied, to the trigger electrode of the relay, iniates the discharge therein and the condenser discharges through the lamp. The output circuit of the relay is of small impedance so that an intense flash of short duration results.

Title: Improvements relating to thermal switches for controlling electric motors
IPC: H01H37/66
Filed: 1939-04-26
Abstract: 528,022. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. April 26, 1939, No. 12527. Convention date, April 28, 1928. [Class 38 (v)] A motor controller, having an overload switch and starting switch, borne on a thermal element deflecting on rise in temperature in such a way as to operate end and intermediate contacts in a sequence determined by a restraint on the pair. In the example, a bimetal strip 14 bears contacts 19, 23, coacting with stationary contacts 20, 24 respectively. The strip 14 is so constructed that heat is generated in it by the passage of current, and it has also a heater wire 15 in series with it. A permanent magnet 28 on the base holds by attraction one or other of the arms of an armature 27, borne by the strip 14, to cause the contacts 23, 24 to close or open with a snap action. On energizing the mains leads 32, current passes through both sets of contacts to the starting winding S of a split-phase motor M. The initial high current heats the strip 14 and the consequent bowing disengages the contacts 19, 20. Thereafter the motor runs on the running winding R. If overload occurs the heater 15 and strip 14 heat up and the further bowing of the strip will overcome the magnetic restraint and open the contacts 23, 24. On cooling, the starter contacts 19, 20 will close first.
