Title: Improvements in and relating to the treatment of vegetable substances
IPC: F26B11/04
Filed: 1927-07-07
Abstract: 297,900. Carrier Engineering Co., Ltd., and Robertson, K. J. R. July 7, 1927. Limping tea. Tea leaf is withered by treatment first with a warm air current passing in the same direction as the leaf and affecting evaporation of its moisture content, the air being simultaneously cooled, and then with a cool dry atmosphere causing vigorous evaporation of the moisture in the leaf. The same body of air may be employed in both stages. The moisture content of the leaf may be reduced by 10-20 per cent in the first stage. In the method described, the tea is fed through a shoot 3 to a rotating cylinder 1 where it is picked up by baffles and showered through the warm air current. After passing through the cylinder the leaf falls, through an opening 7<a>, on to a moving band 8 which conveys it through a section 11 where the leaf is slightly damped and then through a cooling section 12 where it is treated with air drawn in by a fan 6 through a shaft 13 and casing 14. The leaf is then discharged. The air passes from the cooling section 12 through a casing 15, a conduit 16, and a steam or other heater 18 to the fan 6 which next forces it through the cylinder 1. A spray device may also be included in conduit 16 and with the heater 18 may be under control of a hygrostatic or thermostatic regulator 20 in the air outlet shaft 7 of the apparatus. The temperature of the leaf is not allowed to exceed about 95‹ F. and that of the air 120‹ F., the relative humidity of the air being about 30 per cent. Where the temperature and humidity of the outside air corresponds to these limits the air may be drawn directly'into the fan 6 without prior treatment.

Title: Circuit arrangement for the automatic storing and distribution of calls in trunk exchanges
IPC: H04M3/523
Filed: 1952-07-18
Abstract: 723,372. Automatic - exchange systems. STANDARD TELEPHONES & CABLES, Ltd. July 18, 1952 [Aug. 10, 1951], No. 18214/52. Class 40 (4). In a system in which calls incoming to operators' positions are queued when all the operators are busy, each outlet of the distributers can be used to give access to both an operator's position and a queue position. Each distributer has two test wipers, one being connected in place of the other when all the operators are busy. When a distributer MW finds a free operator's position, a circuit is completed over the test wiper c for relay P, which extends the line wires a, b and busies the outlet. When the last free operator's position is seized, relay G in the queue control circuit releases, so that, on the next distributer being taken into use, relay F disconnects the test wiper c and the distributer tests over the test wiper d for the first queue position. Test relay Pa operates in series with W and the first queue relay NA. Subsequent calls are queued by their distributers being stopped at the preceding queue outlets and the corresponding queue relays NB . . . NN are operated. Lamps LI . . . LN show the number of calls queued and lamps Ls, Lf indicate whether the last queue movement was due to a call entering or a call leaving the queue. When an operator is ready to take a call, G is operated to release the test relay Pa of the distributer in the first queue position and, the associated relay W being operated, this distributer hunts for the marked outlet to the free operator's position, whereupon a circuit is completed over test wiper c for P to release W. When, following the release of W, the first queue relay NA falls back, the second distributer in the queue steps up and its relay W operates. Each distributer thereupon steps up one position in turn. When the queue has emptied and an operator is available relay F releases.

Title: Method for treating chrysotile asbestos
IPC: C04B20/08
Filed: 1966-04-27
Abstract: A method of treating chrysotile asbestos comprises the preparation of an aqueous colloidal dispersion of up to 5% by weight chrysotile asbestos fibres, adjusting the pH to 6.0-10.5, therebc flocculating the asbestos fibres, filtering and drying these fibres.  In the flocculation step, a water-soluble alkaline reagent is used to adjust the pH.  Suitable materials are ammonium hydroxide, sodium hydroxide, sodium carbonate, sodium phosphate, potassium hydroxide, potassium carbonate, potassium hydroxide, potassium carbonate, and strontium hydroxide.  The fibres can be redispersed by taking up to 5% by weight of filtered fibres and adding to water which contains no more than 100 p.p.m. of monovalent anions and no more than 10 p.p.m. of multivalent anions, such as deionized or distilled water.  The dispersion is stable in the pH range 4.0 to 6.0.  Adjustment of pH to this range may be made with any monobasic carboxylic acid having up to six carbon atoms or with inorganic acids such as nitrous or hydrochloric acid.  Formic and acetic acid are the preferred organic acids.

Abstract: 708,907. Filtering gases. AMERICAN FELT CO. July 22, 1950, No. 18364/50. Class 8 (2). [Also in Group VIII] A self-sustaining fibrous unit suitable for filters comprises intermingled fusible and non-fusible fibres forming a relatively soft central area, and a surrounding marginal zone into which some of the central fibres extend and in which the fibres are bonded together by heat and pressure to form a relatively thin and stiff peripheral rim. A bat 10 of mixed cotton and cellulose acetate fibres is laid on a platen 11 of a press, and pressed by a heated upper platen 12 carrying a ring die 14 which has a circumferential cutting flange 15, to produce a circular filter unit with a thin, hard, resilient rim 16 of fused fibres. The centre dome-shaped portion may be uncompressed or slightly compressed according to the depth of the ring. A filter unit convex on both sides may be made by pressing the bat between two ring dies, or by sticking two units made as shown back-to-back. A separable sheet of paper or fabric may be placed between the die and the bat to avoid an abrupt break between the thin edge and the dome-shaped portion. Alternatively one or more layers of fabric or felt may be pressed with the bat on one or both sides, and caused to adhere to the rim by applying an adhesive or employing bonding fibres in the fabric. Two bats of mixed fibres may be pressed together with an interposed wire screen to form reinforced filter members. Instead of cotton, the non-fusible fibres may be of wool, rayon, ramie, or silk.

Title: Improvements relating to analogue to digital converters

Abstract: 1,077,717. Analogue to digital converters. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 11, 1964 [May 10, 1963], No. 18502/63. Heading G4H. In an analogue to digital converter an electrical input signal is compared with a first plurality of reference signals simultaneously, and the highest reference signal not exceeding the input signal is subtracted from the latter to yield a remaining signal which is compared with a second plurality of reference signals simultaneously. In Fig. 1 (not shown), an input A.C. signal (1) is compared in comparators (6A to 6J, details in Fig. 2, not shown) with reference signals from taps on a first transformer primary (4) to one end (3) of which a reference voltage is applied. One of the comparators (6A to 6J) enables a corresponding transistor (8A to 8J) and prevents lower comparators from doing likewise, thus causing a further transformer (10) to perform the subtraction mentioned. The remaining signal is applied to further comparators (14A to 14J) for a second subtraction in a similar manner using a third transformer, the end of the primary (12) of which receives onetenth the voltage applied to the first transformer primary from a tap on the latter. The remaining signal (from the third transformer) is applied to more comparators (22A to 22J), one of which gives an output. Thus a three-digit decimal indication is given. Fig. 3 (not shown) shows a further embodiment in which in-phase versions of sine and cosine signals from a resolver are used as the " input " and the " reference " signals, the larger being used as the reference. Other main points of difference from the first embodiment are that the first transformer has two secondaries (and one primary), all tapped according to the tangents of regularly-spaced angles, and that part of the system output (which represents the resolver angle) is provided by gating circuitry.
