Title: Improvements in or relating to rotary sealing devices
Inventor: VOYTECH CHARLES FRANK
IPC: F16J15/38
Filed: 1950-04-24
Abstract: 671,165. Stuffing-box substitutes. CRANE PACKING CO. April 24, 1950, No. 10057/50. Class 122(v) A shaft sealing device comprises a member having a radial surface in sealing contact with a radial surface of a rotatable member, cooling means for the members comprising a housing surrounding the device and defining a chamber therewith, cooling fins on the first member, means on the rotatable member for inducing a coolant flow in the chamber and means on the housing interposed in the coolant flow ahead of the fins to eliminate any substantial tangential component of the coolant flow relative to the fins. Fluid in a space 13 through which a rotating shaft 10 passes is sealed by spring-urged rubbing contact between two radial faces 21, 24 respectively disposed on a rotating collar 15 sealed to the shaft by a packing ring 16 and on a sealing washer 22 sealed to its housing by a packing ring 25. Coolant is supplied to the chamber 36 formed between the sealing device and the housing surrounding it and radially extending cooling fins 52 parallel to the axis of the shaft 10 are formed on the sealing washer 22. A helical movement of the coolant towards the sealing washer 22 is imparted to it by radial vanes 51 carried by the collar 15 and arranged at an angle to the axis of the shaft 10 and the tangential component of the coolant flow, which would cause undesirable torque on the sealing washer 22 by its action on the cooling fins 52 thereon, is substantially eliminated by radial straightener vanes 53 parallel to the cooling fins 53 and formed on the housing 34. .The coolant circulates through an external heat-extracting device 48.

Title: Emergency power supply circuit employing electrical discharge tube converters
IPC: H02J9/06
Filed: 1941-08-08
Abstract: 547,315. Electricity supply. STANDARD TELEPHONES & CABLES, Ltd. Aug. 8, 1941, No. 10079. Convention date, Aug. 14, 1940. [Classes 38 (ii) and 38 (iv)] Substituting sources in service.- When the A.C. supply to an A.C. load circuit fails a device CC, responsive,to the supply voltage causes the release of a relay T whereby a relay TR disconnects the supply circuit and reverses the connections between a battery B and valve apparatus V 1 , V 2  connected to the load circuit and normally charging the battery B, and whereby a relay GR disables a regulating circuit associated with the grids of the valves and connects a vibrator E to the grid circuit so that inverter operation at supply circuit frequency is obtained. The regulating circuit comprises a large proportion of the voltage of a potentiometer K across the battery B and the output voltage of rectifiers VR which are energized in accordancewith load circuit voltage. When a time delay switch TD has closed and the valves V 1 , V 2  have reached operating temperature their grid potentials are therefore automatically controlled to maintain constant voltage on a D.C. load circuit (not shown) connected across the battery and to maintain a trickle charge. Should the D.C. load increase considerably non-linear resistances V3 cause a relay OL to operate to introduce current regulation by reducing the proportion of battery voltage in the grid circuits ; the resistances V3 are also in the grid circuit and assist in the current regulation. The capacity of the commutating condensers C 1 , C 2  is such as to give the plate circuits of the valves such a power factor as will cause the transformer Tl to deliver the appropriate output voltage.

Title: Improvements in or relating to matrix circuit arrangements
IPC: H03K17/62
Filed: 1963-03-14
Abstract: 1,015,451. Atomatic exchange systems. SIEMENS & HALSKE A.G. March 14, 1963 [March 15, 1962], No. 10083/63. Heading H4K. In a cross-point switching network in which each cross-point comprises a rectifier and relay coil connected in series between a row and column conductor, the cross-points are normally biased off by means of potential sources connected through resistances to the row and column conductors and a particular cross-point is rendered conductive by the application, to the relevant row and column conductors, of a potential of opposite polarity and lower absolute value than the bias potential. Thus, as shown, column conductors Xl to Xm and non-conductors Y1 to Yn are connected via resistors Rx1 to Rxm and Ryl to Ryn respectively to potential source - U and + U. A cross-point, e.g. R43, G43, is selected by closing the contacts x4, y3 whereby a potential source + u (less than + U) or a source +U and series resistors W1 and W2 is connected to the row and column conductors in opposition to the bias potential, thus rendering G43 conductive and operating switching relay R43. In order to decrease the loading on contacts x1, y1 &c., transistors may be included in the circuit between terminals a, b and source + U thereby ensuring that current surges through these contacts when they are operated and released are avoided (Fig. 2, not shown).

Title: Improved process for caramelising farinaceous food stuffs and apparatus therefor
IPC: A23L7/157
Filed: 1925-04-18
Abstract: 254,047. Brookes, S. April 18, 1925. Roasting granular substances. - Caramelized ground bread is produced by drying bread, grinding it into crumbs, passing the crumbs through a rotary inclined cylinder gas-heated from the outside so that a uniform heat is applied to the crumbs to brown them, and finally cooling the browned material by passing it through a second rotary cylinder which is either provided on the outside with pipes, or is formed in its walls with passages, for cooling water. Fig. 1 shows the apparatus used for browning the crumbs. The cylinder A is heated by gas burners C and is fitted with ribs or projections for agitating the material as it passes through. A slide or damper d regulates the feed from a hopper D. The cylinder is carried by arms a<1> upon a driving-shaft a. which is mounted in bearings b and fitted with fast and loose pulleys B. After leaving the cooling cylinder the material may be automatically weighed and packed. The Provisional Specification refers to the treatment of farinaceous foodstuffs and states that the heating cylinder is surrounded by a casing formed of, or packed with, non-conducting material such as asbestos.

Title: Making dies for the production of reduced replicas of dolls' heads and other articles
IPC: B29C41/18
Filed: 1953-04-14
Abstract: In a method for reproducing an article on a reduced scale, a duplicate of the article is first made from a polyvinyl resin (e.g. polyvinyl chloride or P.V.C.-acetate) containing plasticizer (e.g. dioctyl phthalate) in an amount equal by weight to that of the resin. The duplicate is then shrunk by immersion in a solvent which will leach out a selected amount of the plasticizer, e.g. commercial ethyl alcohol, ethyl acetate and mixtures thereof.  The reduced replica is then dried and used to make a mould by electro-forming.  A liquid moulding composition is applied to the interior wall of the mould to form a thin liquid film and the mould is heated to set the film.  The shrinking procedure may be effected in steps to make a series of reduced replicas of the original article, e.g. dolls' heads.  The final articles may be of thermoplastic or thermosetting material.  In an example, the composition of one initial duplicate of a head, in percentage by weight, was: P.V.C. 49, dioctyl phthalate 49, lead silicate 2.  The leaching solvent used was a mixture of 3 parts by weight of commercial ethyl alcohol with 1 of commercial ethyl acetate, and the head was immersed in the solvent for 48 hours at a temperature of 20 DEG C. to 25 DEG C.  As a result the head was shrunk by about 17.7 per cent, the reduced replica being then used to make a mould.
