Title: Process for preparing propylene glycol alginate
IPC: A23L29/256
Filed: 1970-09-21
Abstract: 1314077 Propylene glycol alginate GRINDSTEDVAERKET AS 21 Sept 1970 [29 Sept 1969] 44837/70 Heading C3U Propylene glycol alginate is prepared by reacting alginic acid or partially-neutralized alginic acid with propylene oxide in the presence of a diluent in a reaction vessel 3, in which vessel the alginic acid starting material is retained by means 15 adapted to allow passage of liquids and gases, the propylene oxide and diluent passing through the retaining means until the reaction is complete. The alginic acid may be held stationary in the reaction vessel, in a basket of wire gauze or plastics netting (e.g. polypropylene) or held between perforated discs or wire netting (15) in the reactor. Alternatively the holding means may convey the alginic acid through a reactor. An imperforate screw conveyer in a perforated housing may be used, the diluent and propylene oxide passing through the housing, or a perforate screw in an imperforate housing, the diluent and propylene oxide passing countercurrent to the alginic acid. The reaction may be at 45-90‹ C. for 5 minutes to 5 hours. Preferably 1-25 moles propylene oxide is used per mole alginic acid. The diluent may be methanol, ethanol, isopropanol, acetone or methyl ethyl ketone.

Title: Method for reproducibly fabricating and using stable thermal-field emission cathodes
IPC: H01J1/304
Filed: 1973-09-26
Abstract: 1445695 Cathode materials and processing LINFIELD RESEARCH INSTITUTE 26 Sept 1973 [29 Sept 1972] 45081/73 Heading HID A method of forming a heated field emission cathode from a metal wire having a body centred cubic crystalline structure with the (100) plane parallel with the wire axis, comprises a conical tip on the end of the wire; heating the tip in a partial vacuum containing O 2  to desorb surface contaminants including carbon but not surface oxides of the wire; heating to another temperature to ensure surface mobility at the tip but not to remove surface oxides; and applying a potential to initiate build up of the (100) plane and faceting of the (110) and (112) planes thereby forming an axially disposed tetrahedral endform. The pointed wire is attached to a W hairpin heater and mounted in a scanning electron microscope which is then evacuated to 10<SP>-8</SP> torr. The cathode is heated to 1700-1900K using pulsed D.C. or A.C. to outgas impurities particularly C which diffuses to the surface and is oxidized. O 2  is introduced into the tube if necessary. With the cathode at 1400-1800K to ensure surface mobility a field is applied. Build up of the (100) plane occurs and the current sharply increases. The current is limited to prevent arcing. The process is continued until a stable state is reached. If the cathode deteriorates, indicated by a lower quality image, it can be restored by removing the field and reapplying it with the cathode at 1600-1700K causing build up and increased current. The method above is used until the stable state is achieved. The wire may be of W, Mo or Ta. The cathode may be used in electron microprobes, integrated circuit mask fabrication and electron beam access memory devices.

Abstract: 978,268. Card indexes. LAUGHTON & SONS Ltd. Dec. 17, 1962 [Dec. 20, 1961], No. 45575/61. Heading B6E. A card index, e.g. for telephone numbers, comprising a stack of cards having stepped cut-away portions and disposed in a box having a lid which may be raised with one or more cards to reveal a selected card, is characterized in that selection of the card to be revealed is effected by a slider movable along the cutaway portions of the cards, the slides being coupled to a dial, generally similar in appearance to a telephone dial, by means of a spring strip which is wound and unwound in response to rotation of the dial, so that the extent of movement of the slider is dependent on the extent of rotation of the dial. The stack of index cards 27 is supported on a platform 14 in the base of the box 10. The latter has side walls 11 and is closed by a lid 16 having depending flanges 17 spaced from the side walls 11, Fig. 6. A slider 28 having arms 29 is mounted on the lid. The free ends of arms 29 are bent around the flanges 17 to form fingers 30 underlying the stepped cut-away edges of the index cards. The slider has an upturned lug 34 guided in a member 31 and is connected to a twopart housing 38 by a spring strip 37. The housing comprises a lower part 40 having an upstanding wall 42 and an inner part 39 having a depending wall 41. The two parts are slotted to receive the spring strip 37, which passes between the walls 41, 42 and into a coil in the centre of the housing. The spring strip is riveted to the wall 41 and its free end is attached to a lug pressed out of the lower part. The latter is fixed relative to the lid. The inner part 39 is rotatably mounted on a bushing 46 and is rotated by a dial 55, coupled thereto by a lug 57. The dial is provided with circular cavities bearing letters of the alphabet and a downturned peripheral flange 63 having notches 62 between adjacent cavities. A spring-biased member is pivoted at 58 to the lid, has a finger stop 59 overlying the dial, and a latch 68 extending downwardly through an aperture in the lid to engage a blade spring 70 and maintain the lid in its closed position against the action of springs 19. On dialling a letter, one's finger strikes the stop 59 to pivot the member, whereby the latch 68 is disengaged from the blade spring to free the lid and a catch 61 engages one of the notches 62 to hold the dial in position against the action of the spring strip 37. Also, rotation of the dial moves the slider a corresponding amount to underlie the appropriate index card. The index cards are filed on arcuate posts 23 carried by a pivoted plate 20, held in position by a leaf spring 26. The posts project through slots 24 in the lid, when the latter is closed. A protective covering 73 dips over the lid.

In an A.C. or D.C. electrical power supply system having a plurality of stations supplying current to a pair of conductors e.g. as in a rail traction system, one or more of the stations has a step voltage reduction characteristic at a determined value of current so that a greater portion of load current will be drawn from an adjacent station. The voltage reduction may be achieved by means of a series transductor normally D.C. saturated which de-saturates at the determined current. It is stated that fault current protective devices may be set at a lower level. In a 750 volt D.C. traction system a voltage reduction of 150 volts is proposed.
