In order to simulate a sign of the dischargetube type, an illuminated display comprises a housing 4 adapted to contain a light source, the display surface comprising at least one aperture shaped to define part of the design, said aperture being filled with coloured light-transmitting strip material 12 or 12<SP>1</SP>, such that the thickness of the strip fills the aperture and the width of the strip projects outwardly from the display surface. Areas of the latter lying adjacent the strip bear fluorescent paint. As described, the display surface is formed by a translucent sheet 2 of plastic coated with an opaque lacquer 21 which defines e.g. the outlines of the letters of a word and the outline of an animal, Fig. 1. The letters and the animal's outline are also formed by the strip-bearing apertures, which in the case of the letters may be formed either centrally of their strokes, Fig. 1, or surrounding their borders. Fig. 3, see also Fig. 2 (not shown). Similarly, strips 14 help to define the line features of the animal. A transparent cover (18), Fig. 5 (not shown), protects the display surface. Preferably the strips 12 or 12<SP>1</SP> contain a fluorescent dye, and the strokes of the letters are coloured at 23, Fig. 3, in a similar shade, which may also provide details of the animal figure. The lacquer 21 and colouring 23 may be applied by silk screen printing.

Title: Improvements in or relating to stabilised animal feeds containing antibiotics
IPC: A23K20/195
Filed: 1961-05-30
Abstract: An animal feed composition containing or comprising the harvest mash solids produced by the elaboration of Streptomyces aureofaciens or Streptomyces rimosus is stabilized against losses in antibiotic potency by addition of sufficient base, such as calcium or sodium hydroxide, so as to maintain the pH between 6 and 13 (measured when the feed is diluted with water to a slurry of about 10% solids content).  According to an example, a 1-litre portion of harvest mash obtained as a result of a Streptomyces aureofaciens fermentation for 120 hours at 28 DEG  C. was adjusted to pH 1.7 by the addition of concentrated hydrochloric acid.  A 20-gram quantity of diatomaceous earth filter-aid and 2 grams of magnesium silicate were added, and after stirring for five minutes, 15N sodium hydroxide solution was used to adjust the pH to 8.4.  The slurry was filtered and the filter cake dried.  A 0.5-gram portion of the filter cake solids was incorporated in 100 grams of a chick formulation; a pH of 9.0 was maintained in the resultant feed supplement by addition of 2.0 grams of calcium hydroxide.  Specification 689,594 also is referred to.

Rows of identical blanks 6, 7, 14 or 15 are stamped out of a wide, rolled strip 1, which is thinner at its edges than at its centre, and so the blanks have a generally trapeziform crosssection. The blanks are fed individually to a first station (23) at a turntable device of a slotting machine, Fig. 4 (not shown), and then transferred to a work station (24), where each blank is centred by a mandrel 29. A rotating magnet 27 turns a ring 28 and a solenoid 32 moves a spring- loaded head 34 upwardly. The head enters the cut-out 12, 13, 20 or 21 in the blank, the magnet continuing to turn as its travel is 400 degrees. The next blank is engaged by a head 35 which is diametrically opposite the head 34 so that adjacent blanks are at 180 degrees to each other. The blanks are moved to a slotting station (25) and to a station (26) for removal from the device. The laminations are then stacked and the stack is of rectangular cross-section in its axial plane, Fig. 6 (not shown).

If P1 is equal to the supply pressure PS and is above an optimum pressure determined by the dimensions of the device the characteristic will have a short operating time with some hysteresis which can be reduced by making P1 equal the optimum pressure. A curved characteristic is obtained by making P1 less than the optimum value.

Abstract: 1362100 AFC; frequency modulators; Gunn oscillators SELENIA-INDUSTRIE ELETTRONICHE ASSOCIATE SpA 5 Oct 1972 [5 Oct 1971] 46020/72 Headings H3A H3R and H3T A tunable, negative resistance, diode oscillator 14, Fig. 3, has a resonant cavity 10, Fig. 2, containing a ferrite 12, means 13 for producing in the cavity an adjustable magnetic field, adjustment of which adjusts the frequency of the oscillator, and an automatic frequency control (A.F.C.) circuit 18, 19 which operates to control the power supply to the negative resistance diode in dependence on the oscillator frequency and thereby to provide A.F.C. over the oscillator frequency. As shown the oscillator uses a Gunn diode located in the resonant cavity which is partly defined by a waveguide 10 which is partly loaded with a dielectric 11 surrounding a ferrite 12. The frequency of the oscillator 14 is varied by a slow A.F.C. tuning circuit which energizes a coil 13 so as to produce the magnetic field. This causes the ferrite 12 to produce a phase-shifting effect so that the magnitude of the field determines the frequency of the oscillator. The oscillator feeds a load 15 through a directional coupler 17 and a line 16. A fast A.F.C. is provided by a discriminator 18 and an amplifier 19 the output of which is used to control the supply voltage applied to the oscillator Gunn diode to maintain the frequency constant. The cavity may be loaded with a yttrium iron garnet and the oscillator may be used as a local oscillator in a receiver.

Title: An Electronic Calculator.
IPC: G06F7/50
Filed: 1967-10-09
Abstract: 1,192,240. Calculators. INTERNATIONAL BUSINESS MACHINES CORP. 9 Oct., 1967 [24 Oct., 1966], No. 46072/67. Heading G4A. An electronic calculator for accumulating a plurality of totals comprises a recirculating store and means for generating and inserting into it an address character and two digit characters representing digits of the same order in different totals, the digit characters being subsequently accessible by reference to the address character. In Fig. 1, a recirculating register comprising a magnetostrictive delay line 50 (which may be replaced by a shift register) and a register B holds six words each relating to a corresponding decimal order and each consisting of an address decimal digit, a minor total decimal digit, a grand total decimal digit and a space, the totals digits being in excess-3 form and the address digit being straight binary-coded. Thus the loop holds a minor total accumulator and a grand total accumulator. Control keys 12 consist of add, subtract, subtotal, total, print only, keyboard clear, power-on-and-initialreset, and readout-and-reset-grand-total-accumulator keys, the last two being lockable. Description keys 14 consist of 3 banks of 9 keys for entering a merchandise identification number. Amount keys 16 consist of 5 banks of 9 keys for entering monetary amounts. After setting keys 14, 16, the operator presses the add key which causes the address characters to be loaded into the recirculating register, the characters being provided by timing circuits to decoder 18 where they go via register A and circuit correction 500 into the recirculating register. The settings of the keys 12, 16, 14 in that order are scanned, decoded at 18, inserted into register A and printed and displayed at 60. The settings of keys 16 are taken from register A and added into the minor total accumulator by feeding a serial full adder-subtractor 300 from register A (via gates 400) and the recirculating register (via gates 200) the result digits passing through register A and correction circuit 500 (provided in view of the excess-3 notation) into the recirculating registers. Subsequent transactions can be entered in the same way. Pressing the subtotal key causes the minor total accumulator to be emptied via adder-subtractor 300 and register A to be printdisplayed at 60, the data being reinserted into the minor total accumulator. Pressing the total key has similar results except that instead of reinsertion as before the data is added into the grand total accumulator. Decimal points and dollar signs are supplied to print-display unit 60 automatically.

The organic substance may be acrolein, acrylonitrile, or a solution of styrene in benzene. Tetrahydrofurfuryl alcohol or isopropyl alcohol may be added to promote mixing of the salt solution and the organic substance. The mixture may be dripped into aqueous ammonia to precipitate ammonium uranate and to form microspheres. After ageing by contact with the alkaline solution or with gaseous ammonia, the microspheres are washed and dried in hot air or by azeotropic distillation. Finally the product is heated in steps up to 1300‹ or 1500‹ C. in mixtures of argon with hydrogen up to 600‹ C. or with carbon monoxide, and cooled, also in steps. The microspheres may be used as fuel in high temperature gas-cooled reactors or may be used in the preparation of carbide fuel.
