Abstract: 782,663. Photo-electric arrangements. WESTERN ELECTRIC CO., Inc. March 4, 1955 [March 5, 1954], No. 6455/55. Class 40 (3) [Also in Groups XXXV and XXXVI] A photo-sensitive element for converting solar radiation into electrical energy comprises a silicon body having a PN junction, the thickness of either the p or n zone being of the order of the diffusion length and small enough to allow the radiation to reach the junction. The device may be associated with a storage battery, a rectifier also being provided so that the device may charge the battery but the battery cannot discharge through the device. Fig. 1 shows a body 11 of n-type silicon having a thin surrounding p-type layer 13. The p region may be produced by heating an n-type silicon wafer to 1000‹ C. for 5¢ hours in an atmosphere of boron trichloride. Low-resistance connections 18 and 19 to the p layer can be provided by electroplating rhodium direct on to the boron diffused layer without first roughening the surface. The p layer is partially removed to allow low-resistance connection 17 to be provided to the n-type body, and insulation 21 and 22 is provided to reduce current leakage. Solar radiation on surface 14 reaches the PN junction, and can produce an electrical output of approximately one watt. Reflection losses can be reduced by coating the silicon with a layer 20 of material having a refractive index between that of silicon and of the atmosphere. Such material may consist of polystyrene or silicon dioxide. A plurality of cells may be connected in series or parallel, and arranged in a non-horizontal position with reflector means for concentrating the solar energy.

Title: Alginic acid esters and their water-soluble salts
Inventor: SNYDER ERIC GERHARR
Filed: 1950-03-16
Abstract: The invention comprises alginic acid esters of sulphuric acid, water soluble salts thereof and a blood anticoagulant comprising an aqueous solution of non-toxic salts of alginic acid esters of sulphuric acid. The alginic acid esters of sulphuric acid are produced by a process which comprises reacting alginic acid containing less than 10 per cent and preferably less than 2 per cent by weight of moisture with chlorosulphonic acid in the presence of an anhydrous acid-acceptor which is an organic base at an elevated temperature below the boiling point of water and in the absence of moisture other than that contained in the alginic acid.  The acid acceptors are in general tertiary amines such as pyridine, the methyl pyridines, quinoline and dimethylaniline. The sulphonation mixture may be fractionated into low-, intermediate- and high sulphur fractions on the basis of water solubility.  In the example alginic acid is warmed with dry pyridine and chlorosulphonic acid, the cooled reaction mixture is poured into cold water and the alginic acid sulphate ester pyridinium salt is precipitated by adding methanol ethanol or other water soluble aliphatic alcohol and the product is washed and dried.  The product is stirred with successive portions of water and centrifuged, products of lower solubility and sulphur content being removed with each.  The sodium salts are formed by the addition of caustic soda to each aqueous fraction followed by methanol, ethanol or other water-soluble aliphatic alcohol.  The precipitated products are washed and dried.  The anticoagulant effects and toxicity of the sodium alginic acid sulphates are evaluated in laboratory animals using aqueous solutions of the salts, the pH of the solution being adjusted to 7 with hydrochloric acid or sodium hydroxide.  The alginic acid starting material is obtained by treating sodium alginate with dilute hydrochloric acid and washing and drying the product.

Abstract: 527,426. Counting railway vehicle wheels. STANDARD TELEPHONES & CABLES, Ltd., BARNARD, R. M., GLOVER, W. F. and BROWN, A. March 3, 1939, No. 7083. [Class 105] [Also in Group XXXVI] In an arrangement for counting passing railway vehicle wheels, the wheels pass between two coils arranged on opposite sides of the rail, one coil being supplied with high-frequency alternating current, the other picking up energy which is reduced during the passage of a wheel. As shown two pairs of coils are located at the ends of a track section. Coils RCA1, RCB1, between the rails R1, are supplied with high-frequency current from an oscillator O. One pole of each coil is presented to a single pole of the corresponding pick-up coil RCA2, RCB2 and the energy picked up is applied respectively to the grid of a high slope pentode valve PVA, PVB. The coil circuits are tuned to resonance by condensers TC. Anode current from the valves is supplied to corresponding relays TRA, TRB. The valves may be biassed so that this anode current falls to substantially zero during passage of a wheel, or the relay may have two windings one of which is supplied with steady current opposing the valve output current so that the relay drops its armature when the output current falls to a predetermined value greater than zero, in which case it is unnecessary to bias the valve.. Two pick-up coils suitably spaced along the line may be associated with a single energized coil to indicate direction of travel. Specification 447,866 is referred to.

March 9, 1932, No. 7115. [Class 37.] In apparatus for measuring the loudness equivalent of audio-frequency electrical waves wherein said electrical waves cause actuation of an indicating device, means are provided for weighting the electrical waves in their effect on the indicating device in accordance with the trequency-energy characteristic of the human ear at or about the loudness level to be measured. A condenser microphone 1 converts sound .into electric waves which are amplified in an amplifier 2 and passed through a calibrated uniform attenuator 3 comprising variable .resistances 4, 5, 6 and through an amplifier 9 to the input to a third amplifier 17 in the anode circuit of which a thermocouple 18 and micro-ammeter 19 are coupled. The input to the valve 17 comprises three attenuation circuits 10, 11, 12 any one of which may be witched in by switches 13, 14 and each circuit comprises an inductive element L, resistances R1, R2 and condensers C1, C2 so proportioned that the resultant frequency-attenuation characteristic bears a particular relation to the loudness characteristic of the human ear at the loudness of the sound being measured. The frequency-attenuation characteristic of each circuit is related to one or other of the " Threshold of audibility," " Medium loud," and " Very loud " characteristics of the human ear and hence the effect of a sound in the instrument 19 is similar to that which it would have on the human ear. For a given input strength above an initial sound level at 1, the attenuator 3 may be adjusted so that the instrument 19 remains at the initial reading, in which case the reading of the attenuator 3 gives the loudness of the sound waves above their initial level by a " null " method. On the other hand the micro-ammeter 19 may be calibrated to read in terms of the energy level of the signals applied to it.
