Title: The preparation of anti-lipaemic agents
Inventor: GOLLIN RONALD ARTHUR
IPC: C08B37/12
Filed: 1959-12-24
Abstract: From 0,9 to 2,0 sulphate groups per monosaccharide residue are introduced into laminarin or partially degraded laminarin by reaction with sulphur trioxide in a solvent medium comprising a dialkyl formamide or acetamide wherein each alkyl group is methyl or ethyl. The laminarin or partially degraded laminarin may have a molecular weight of 1,500-3,500.  Degradation may be effected enzymically or by hydrolysis with hydrochloric acid.  Undegraded laminarin should be sulphated at a temperature not exceeding 0 DEG C. Sulphation is preferably effected at -20 DEG -30 DEG C.  The sulphur trioxide may be added as a complex with dimethyl or diethyl formamide or acetamide.  The reaction is preferably carried out in the absence of moisture.  The resulting laminarin sulphuric acid may be converted to the sodium, potassium, or calcium salt by treatment with an aqueous solution of the appropriate alkali.  The salt may be purified by treatment with sodium permanganate, dialysis, or intermediate formation of the waterinsoluble dimethyldodecylamine salt.  One salt may be converted to another by ion exchange or double decomposition. The sodium and calcium salts may be precipitated from solution by treatment with alcohol and acetone respectively.  Examples are given.ALSO:A composition for treating lipaemia and atherosclerosis comprises an aqueous solution of a laminarin sulphate containing 0.9-2.0 sulphate groups per monosaccharide residue (see Group IV (a)).  Sodium, potassium, or calcium laminarin sulphate may be employed.  The solution may have a strength of 5-10%.  1-3 cc. of the solution may be contained in an ampoule.  The tonicity of the solution may be adjusted by the addition of glycerol or sodium chloride.  The solution may also contain phenol, cresol or methyl p-hydroxy benzoate (the latter being added as a solution in alcohol) as preservative or sodium metabisulphate or acetone bisulphate as anti-oxidant.  Delayed action compositions may be prepared by dissolving in Pitkins menstruum (an aqueous solution of gelatin, dextrose and acetic acid) or suspending in an aqueous solution of carboxymethyl cellulose or polyethylene glycol.

An asymmetrically conducting diode comprises a body of semi-conductor material including two outer regions of one conductivity type and an intermediate region of opposite conductivity type wherein one of said outer regions has a major portion of substantially uniform thickness and at least one minor portion which is relatively much thinner than the major portion, the diode having a negative resistance characteristic with the junction between the one outer region and the intermediate region biased in the forward direction with a relatively low breakover voltage and no negative resistance characteristic with the junction reversed biased, and an electrode attached to each one of the two outer regions. A P-type silicon body 2 of resistivity 0À1-0À2 ohm. cm. is doped with phosphorus to give two saturated N + -type regions 4 and 6 containing 10<SP>21</SP> impurity atoms/ c.c. Nickel layers 14 and 20 are applied by electrolytic techniques and then alloyed to the silicon. Nickel layers 16 and 22 are applied and then the wafer is dipped into a lead bath to give layers 18 and 24. In the manufacturing process described, a plurality of devices are formed simultaneously using photoresist and oxide masking techniques with POCl 3  as the phosphorus source (Figs. 2a-2#, not shown). After treatment with POCl 3  the devices are heated to allow further diffusion of phosphorus. Alternatively a second doping with phosphorus may be made. The devices are separated by etching or scribing, their edge portions removed and lead wires 26 and 28 applied. Ge and GaAs may be used as the semi-conductor body whilst nickel may be replaced by gold. The breakover voltage of the device may be selected by adjusting the resistivity of the middle layer. The switching voltage difference may be modified by sowly cooling or annealing the devices during manufacture, this raises the life-time of the carriers. The number of thin portions 12 effects the break-down voltage.

Title: Electronic calculator having an adder with selectively enabled carry
IPC: G06F7/50
Filed: 1975-11-18
Abstract: 1526057 Electronic calculators; displays TEXAS INSTRUMENTS Inc 18 Nov 1975 [26 Nov 1974 (7)] 47448/75 Headings G4A and G4H An electronic calculator includes an arithmetic unit 30A, Fig. 4G, including a plurality of single-bit adder sections 32A-D each adding two input bits and an input carry from any previous section to produce an output sum and to couple an output carry C to any next section, and controllable logic means 147, 140, 133 selectively enabling and disabling the carrier from section to section in accordance with commands, so that the arithmetic unit can operate as a parallel adder or as a plurality of single-bit adders. The calculator includes a keyboard input and a LED output, and the drivers for the LED output and the calculator circuitry are fabricated on a single I<SP>2</SP>L semiconductor chip. Commands are issued by a programmed read-only memory and data is stored in a random-access memory, a particular bit of each command word determining whether the arithmetic unit operates as a parallel adder or as a plurality of single-bit adders. When a numeric or function entry key is actuated, a corresponding address is set up in a subroutine register which results in a branch to the appropriate number entry routine or function execution routine, by loading the contents of the subroutine register into a programme counter, the contents of the programme counter being meanwhile saved in the subroutine register. A power-up clear latch using gates which take preferential states when the calculator is powered-up causes the programme counter to increment until it reaches and stops at a predetermined value. The random-access memory may be addressed directly using the first five bits of a command word or indirectly using the first four bits of a random-access memory address register and the fifth bit of a command word. When the arithmetic unit is used as a plurality of single-bit adders, they may be used for toggling flag bits and for twoscomplement subtraction. A segment decoder 35A, Fig. 4C, and a digit decoder 36A for the LED output each comprise gating networks coupled to the inputs and outputs of a programmed logic array, the inputs to the logic array being latched at 871, 872-871C, 872C and 871D, 872D-871F, 872F which enables the display to be continuous while the calculator is performing other operations. Latching at the inputs rather than at the outputs reduces the number of gates required on the chip. The drivers 8S-14S and 17S and 15D-21D are as shown in Fig. 5 and, since more current is required to keep a segment off than on, when all segments of a given digit are off the digit driver is also turned off to reduce current drain. This is accomplished by blocking the outputs of the segment and digit decoders.
