Title: Improvements relating to the drying of grass and crops generally
IPC: F26B17/10
Filed: 1936-03-02
Abstract: 471,484. Drying grass &c. GREENWEL, SIR B. E. March 2, 1936, No. 6311. [Class 34 (ii)] A process of drying grass and crops generally consists in promoting a flow of the material together with a high temperature inert gas, such as carbon dioxide. In the apparatus shown, a carbon dioxide producer 1 is connected at 9 to a sinuous duct system 2, and the gas together with the grass or other material delivered from an endless conveyer 4 and through a rotary valve 8, is conveyed through the duct by means of a suction fan 10. The material is delivered to a cyclone separator. In a modification the fiow of material is assisted by means of a pressure fan at the inlet end of the duct 2.

Title: Improvements in or relating to methods and apparatus for recording electrical variations for example for sound recording
IPC: G11B7/00
Filed: 1930-02-25
Abstract: 349,469. Recording by photographic means. PRISNER, S. and WENDER, E., 1, Mowbray Road, Kilburn, London. Feb. 25, 1930, No. 6317. [Class 106 (iv).] A method of recording electrical variations, particularly intended for recording sound, consists in mechanically acting, by means of a vibrating stylus, upon a photographic film or like surface, whereby the action of the stylus upon the sensitive material produces a record resembling one obtainable by the action of light. An electromagnetic device similar to an ordinary sound-recorder may be used, the cutting tool being replaced by a stylus which tapers to a small area having its greater dimension transverse to the film. The stylus vibrates in contact with the film in a direction at right angles to the direction of travel of the film, and so produces an effect which after development of the film appears as a trace resembling a " variable area " record made by the usual optical method. Alternatively, the recording stylus may be tapered to a rounded point, and arranged to act upon the record surface by variations of pressure thereon, so as to produce a record trace of varying intensity. Both methods of recording may be used in combination. The invention may also be applied to making records on discs, having the trace in spiral form. Reproduction from records made in accordance with the invention may be effected by means of apparatus ordinarily used with photographic records.

Abstract: 254,232. Stock, A. March 8, 1926. Specific-gravity estimating-apparatus.-In a magnetic balance for ascertaining the density of gases a permanent magnet or an electro-magnet is secured longitudinally upon the balance beam and its magnetic effect is utilized in bringing the balance to equilibrium. The beam with its magnet M carries a hollow gastight ball K and is disposed in a tube T containing the gas whose density is to be ascertained.

A resistance r is adjusted to compensate for temperature and pressure of the gas, the normal density at 0‹ C. and 760 mms. being read off directly from the ammeter. If the measurements are indicated by the amplitude of the pointer movements of the beam the magnets M, E may be used solely for correcting the pointer positions at different temperatures and pressures.

Abstract: 1,206,914. Optical apparatus. CARL ZEISSSTIFTUNG [trading as CARL ZEISS]. Feb.7, 1969 [Feb.10, 1968], No.6777/69. Heading G2J. [Also in Division G1] The proportion of sucrose in the total of dissolved substances of Intermediate products in sugar manufacture is determined by measuring the refractive index (n) of a sample and the polarimetric angle of rotation (α) and combining them with the known refractive index (No) of pure water in the quotient α/n-No. The apparatus includes the necessary quotient calculating means which may give both an anologue and a digital indication. An internationally accepted purity quotient can be derived by multiplying the above quotient by factor F which takes into account, polarimetric path length and temperature and either quotient may be used for process control. The polarimetric and refractometer may be connected serially in the flow or in parallel, and the temperature of the samples is controlled, a thermistor in the sample flow path providing temperature compensation in the calculating circuit. Various stages in the process may be sampled and a fixed proportion of a solvent such as pure water is added to each sample by driving the sample and solvent pumps with a common motor, the sample and solvent being mixed in a motor driven mixer.

Abstract: 1,087,436. Monitoring tape feed. OLYMPIA WERKE A.G. Feb. 19, 1965 [May 12, 1964], No. 7238/65. Heading G5R. In an arrangement for indicating feed defects in the movement of a, record tape, for example magnetic or perforated tape, the tape driving arrangement 2 is used to control a pulse generator 4, the leading edge of whose output pulse 40 energizes an input of a bi-stable arrangement 5. The other input to the bi-stable is energized by a pulse derived from a sensing arrangement 3 which detects the passage of the part of the tape which was being driven at 2 at the time of generation of the pulse 40. When the bi-stable is in the condition set by the pulse 40 it delivers an output pulse to the AND gate 7. The trailing edge of the pulse 40 is used to develop a pulse which is also fed to the AND gate 7. Should both inputs to the AND gate overlap in time, an output is derived from the gate to change the state of bi-stable 8 and actuate alarm arrangements. The alarm indicates that no output has been obtained from the sensing head 3 before the end of the pulse 40 and the width of the pulse is such that this condition corresponds to the presence of a fault in the feed arrangements for the tape.

Dynamic braking of a motor 3, 4, e.g. in a battery-powered vehicle, is controlled by variation of the mark/space ratio of a " chopper " 7 from which the field at least is supplied. The ratio is adjusted in response to pedalcontrolled and armature current signals 13, 6 so as to limit the armature current to a value which depends on pedal position. In Fig. 1 braking is effected in a series motor by reversing the connections at 5 to the armature 3, which is shunted by a resistor 9 and diode 10. In Fig. 2 (not shown) the field only is energized during braking, which is either rheostatic or regenerative in this ease. The armature voltage may be sensed to prevent energization of the field with the vehicle stationary. None of the circuit elements are described.

Title: Purification of germanium tetrachloride
IPC: H01L21/00
Filed: 1953-03-17
Abstract: Germanium tetrachloride containing impurities, notably arsenic, is purified by at least once agitating it with aqueous hydrochloric acid having a concentration of at least 8 and preferably 12 normal containing added chlorine and preferably saturated therewith, allowing the mixture to settle into two layers and subsequently separating the layers to recover purified germanium tetrachloride as the lower layer.  The operation is preferably conducted at reduced temperatures.  According to an example scrap germanium containing aluminium, gallium, arsenic, antimony, boron and silicon was chlorinated in a silica vessel to obtain germanium tetrachloride.  To the latter was added 40 per cent by volume of chlorine saturated 12N hydrochloric acid, the mixture agitated and allowed to settle into layers.  The lower layer of germanium tetrachloride was hydrolysed to the dioxide and reduced to the metal which contained about 1 part of arsenic per 2 million parts of germanium.  The process may be continuous, germanium tetrachloride being introduced near the top of a packed column through which an upward flow of chlorine saturated hydrochloric acid solution is maintained.  The tetrachloride inlet is at a point such that an acid layer can form above it and be withdrawn, whilst the acid inlet is such that a tetrachloride layer can form below it and be withdrawn.
