Title: Multi-colour pen or pencil
IPC: B43K24/10
Filed: 1959-12-02
Abstract: 936,464. Writing instruments. K. FEND. Dec. 2, 1959 [Dec. 11, 1958], No. 40925/59. Class 146 (3). In a multi-colour pen or pencil in which writing cartridges 5 are mounted in a telescopic band 1, 2 and in which the desired cartridge is selected by a gravity operated push-rod mounted in the rear barrel-part 1 and projected when the barrel parts are pressed together, the selector rod 6 has an enlarged head accommodated with radial and axial play in an aperture 14 at the rear end of part 1 so that it can pivot about its head when the pen &c. is tilted. The barrel parts are urged apart by a spring 3 and part 1 has a fixed guide tube 4 having a closedend slot 23 in which works a pin 21, 22 on the part 2 to hold the parts assembled and openended slots 15 which guide both the heads of cartridges 5 and the front end of rod 6 while it is being projected. Each cartridge has, at its upper end, a lug 12 working in slots 9 in a fixed guide-tube 7 and slots 11 in a rotatable locking- tube 10 within tube 7. Springs 8 tend to return a projected cartridge. Slots 11 are so shaped that during projection, the lug 12 on the cartridge turns the locking tube and engages under a catch surface thereon when the selector rod and barrel part 1 are released. When a different colour is being projected, lug 12 first rotates the locking tube to free the previously projected colour for retraction by spring 8 and then projects and locks the new colour. The barrel is marked opposite each slot 15 with the colour of the pen &c. projected when rod 6 works in that slot.

Abstract: 1,011,726. Vehicle seats. J. SCHWARZ. Nov. 20, 1961 [Nov. 21, 1960], No. 41509/61. Heading A4J. In a vehicle seat back-rest, a support for the small of the back is vertically and horizontally adjustable, in a direction normal to the plane of the back-rest, by means of a single control knob 16. The plates 31a are pivotally mounted on a spring strip 32 which is fixed to the lower end of a blade spring 21. The upper end of spring 21 is pivotally and slidably mounted in slot 11 of plate 10. The plates 31a are moved forwardly and rearwardly by turning knob 16, and therewith sleeve 13, to extend or retract bolt 12 whose squared end 22 is secured to spring 21. To adjust the vertical position of plates 31a, the whole arrangement is unclamped and moved bodily along slot 11. To effect this, knob 16 is pressed inwardly, thus engaging screw-threaded ring 14, which is turned to effect clamping or unclamping of the sides of slot 11 between the ring 14 and the collar of squared bush 15. Plates 31a may be padded with foam rubber and have eyes for threading on rubber bands 36 and spring strip 32. The seat and back-rest may be connected for movement together in a vertical direction by bar 26, 27. In another form (Figs. 4 and 5, not shown) the upholstery is carried on a vertically slidable frame. The adjustment knob may alternatively be located at the lower edge of the back-rest (Fig. 7, not shown).

The cassette comprises a drawer 2 and a case 1 both of which may be injection moulded. When a catch 19 is released by finger pressure a spring 3 urges the drawer carrying the cassette to the open position where it is checked by pins 15 on the drawer, moving in slots 14 in the case. A guide 11 engages ridges 13 to locate the drawer in the case. The cassette is located on tabs 8 and inclined surfaces 17 on the end wall of the drawer incline the cassette from the open drawer to facilitate its removal. The sides of the drawer are cut away so that the cassette can be easily In modifications, the spring could be a cylindrical coil spring, a leaf spring or a block of foam plastics. The catch 19 could be arranged to engage one of the narrow side walls of the case. The cases can have dovetail shaped projections and slots on their outer surface, Fig. 22, so that a number of cases can be joined side-byside or in tiers. A projection 46 engages in the slots 14 in the adjacent case to lock the cases together. Alternatively, the cases can be moulded together side-by-side, or one on another, or back-to-back. The cases can be engaged in a mounting bracket 60 Fig. 28 by means of the dovetail projections and slots, the bracket being screwed to a supporting surface. Similarly, a handle can be slid on to the dovetail formations so that a number of interengaged cases can be carried as a unit. Labels.-The drawer carries a label (Fig. 16, not shown) of stiff paper, cardboard or a plastics sheet and may have indicia on both sides.

Title: Magnetosensitive element

Filed: 1969-08-22
Abstract: 1279275 Magnetosensitive devices SONY CORP 22 Aug 1969 [24 Aug 1968 (3)] 41945/69 Heading H1K A magnetoresistor comprises p type and n type regions P, N in a body S of intrinsic or weakly semi-conducting material, a polycrystalline region F being provided in the body S so that when the application of a magnetic field perpendicular to the plane of the body S causes charge carriers injected therein from either of the regions P or N to be deflected towards the region F, the relatively high carrier recombination rate in that region causes the resistance of the device between the regions P and N to increase. The effect may be enhanced by diffusing into the region F a dopant such as Au, Cu, Ni, Ag, Zn, Mn, Fe or Pt to decrease the carrier lifetime still further. In the embodiments the device is made of Si or Ge, the polycrystalline region F being formed in an otherwise monocrystalline layer 103 vapour deposited on a substrate, which may subsequently be removed, due to the presence on the substrate surface of locally roughened areas or to the local deposition of material having a different lattice constant to the substrate or of polycrystalline Si or SiO 2 . Individual magnetoresistors may be broken from a common wafer in whichtheyareallsimultaneously formed. An integrated circuit arrangement is also described comprising four such devices in a single semi-conductor body, separated by polycrystalline regions and arranged in such relative polarities that the overall resistance of the arrangement remains unaltered by the application of a magnetic field.

Filed: 1959-12-11
Abstract: Vitamin B12 is obtained by fermenting a medium containing carbohydrates, amino acids and nutrient salts using Propionibacterium shermanii Strain 33 as the organism.  The process is preferably carried out under anaerobic conditions at 28 DEG  to 32 DEG C. at a pH of 6 to 7 with a sugar concentration of 1-2% by weight and for a period of 10-12 days.  The fermentation medium is preferably obtained by mixing a fermentable sugar such as glucose, invert sugar or maltose, with an amino-acid mixture obtained by degrading wheat- or corn-gluten, potato- or soya-protein, casein, blood-, or fish albumin, and with pantothenic acid, biotin, sources of cobalt, sodium, potassium, magnesium, iron, phosphate, sulphate and chloride ions-, yeast extract and 5.6-dimethylbenzimidazole in alcoholic solution. Vitamin B12 may be separated by adjusting the pH to 6, heating to 85-120 DEG C., centrifiuging, adsorbing on active carbon, eluting with an aqueous alcohol such as isopropanol, and then crystallising.  P shermanii Strain 33 is obtained by growing milk curd on a medium containing glucose, casein proteolyzate, casein acid hydrolysate, sodium dihydrogen phosphate, tripotassium phosphate, magnesium chloride hexahydrate, ferrous sulphate heptahydrate, cobalt sulphate heptahydrate, pantothenic acid, biotin and yeast extract, and selectively isolating cells of the diplo form which occur in short chains having at most 4 members.
