Patent GB-577088-A (GB)
Title: Selection controlling circuits
IPC: H04Q1/38
Filed: 1944-04-14
Abstract: 577,088. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. April 14, 1944, No. 6899. Convention date, May 6, 1943. Addition to 573,405. [Class 40 (iv)] [Also in Group XL] Relates to detail modifications of the multipotential marking system described in the parent Specification. As shown in Fig. 1, a register wiper RB connects one of a number of potentials to the grid of a thermionic tube V1 and the cathode of a tube V2 and the selector wiper T connects similar potentials in succession to the grid of V2 and cathode of V 1. The tubes are tetrodes with their second grids connected directly to their cathodes and their characteristics are such that when the potential applied by the selector differs from that selected by the register, current flows in one tube or the other and in the common anode resistance R3. When, however, the two potentials are the same, current ceases and the potential applied to a gas-filled cold cathode tube GV rises to a value at which the tube fires, energizing a relay GVR to stop the switch. In another modification, Fig. 3 (not shown), two triodes with directly heated cathodes have similar reciprocally connected input circuits, but individual anode circuits including relays. This arrangement is such that current flows in the anode circuit of the tube in which the grid is more positive than the cathode, but not in the other. When both grids and both cathodes have the same potential, both anode relays pull up to stop the selector. In another arrangement, Fig. 4, in which the tubes have a push-pull output circuit with the register and selector wipers connected to the respective grids, the anode currents are unequal when the wipers are connected to different potentials and a relay VR is maintained energized through a bridge rectifier S1 ... S4. When the two potentials are the same, the anode currents are equal and VR drops and stops the selector. A double-wound relay VR with oppositely directed single rectifiers associated with its respective windings may be used.

Title: Process for dyeing cellulose fibres
IPC: D06B21/00
Filed: 1974-02-15
Abstract: The wound packages are dyed with soluble dyes or precursors for the development of azo pigments or solubilised vat or sulphur dyes at temperatures of up to 135 DEG C by the exhaust method. For this they are heated and deaerated in a dyeing vessel before dyeing and then brought into contact with the total dyeing liquor, heated separately in a make-up vessel to about dyeing temperature and put under a relative overpressure of 2.9 to 9.8 bar, by transferring the dyeing liquor from the make-up vessel into the dyeing vessel. Thereafter the dyeing treatment is completed by circulating the dyeing liquor. Immediately prior to the transfer of the dyeing liquor the wound packages are subjected to a hot steam (vapour) atmosphere at about the dyeing temperature. The dyeing liquor is then passed into the wound package, simultaneously from the inside and the outside, against the pressure of the air-free hot steam atmosphere. The dyeing process produces uniform dyeings without harming the material.

Title: Machines for feeding solid material in particulate or granular form
IPC: A01C7/18
Filed: 1949-03-16
Abstract: 667,103. Manure and seed distributers. ARNOT, W. D. March 14, 1950 [March 16, 1949], No. 7188/49. Class 6'(i) [Also in Group XXX] Relates to apparatus for feeding solid material in particulate or granular form, such as seeds, of the kind in which the material is contained in a container 4 and in which a small portion of the material is segregated by a plunger 6 reciprocating in relation to the hopper and thereby raised through the material and delivered to the desired point or points. According to the invention, the small portion segregated by the plunger is delivered to the desired point by a blast of air or other gas. In the seed sower shown the plunger 6 is reciprocated within the hopper 4, which is fixed on a wheeled frame 1, by a rocking lever 7 which is given its rocking movements by a star wheel 3 mounted on the front axle 2. The plunger is suitably shaped so that it is unlikely to pick up any seed except in a recess 12 provided for the purpose, and this recess 12 carries the seed to a point within an air duct 17 provided in a head 14. As the plunger approaches its uppermost position it lifts the head 14 against the action of a spring 14a, thus lifting a valve 25, provided on a stem 24 of the head, from its seat 26 and thereby allowing air under pressure to pass through an opening 28 and thence to the duct 17, carrying the seed with it. The seed is carried down a discharge tube to the ground into a furrow made by a coulter 20, the seed being covered by furrow-closing shares 21 which are followed by a consolidating roller 22. The compressed air supply is obtained from a pump 30 whose piston is reciprocated by linkage driven by the star wheel 3; alternatively the pump could be driven by a separate prime mover, or a store of air or gas under pressure may be used. The hopper, its cap and the head 14 may be made of transparent material. In a modification, Fig. 3 (not shown) the air supply is obtained by a bellows mounted within the hopper 4 above the head 14, the bellows being compressed by the head when the latter is moved on each upward stroke of the plunger. In another modification a sped planter is hand-operated, being provided with a handle and a marker plate, and being actuated by placing the foot of the plunger on the ground and by exerting downward pressure on the hopper to produce the necessary relative reciprocating movement between the hopper and plunger.

Title: A process for the production of easily soluble pudding preparations
IPC: A23L9/10
Filed: 1936-03-10
Abstract: Easily soluble pudding preparations are obtained by mixing a solution of fondant sugar with a melt of drop sugar and adding to the mixture the usual starch flour, e.g. rice, maize or potato starch flour, and flavouring substances such as caramelized sugar, almonds, jams, fresh fruits, yolks or whites of eggs, &c., or mixtures thereof, a viscous paste being obtained after cooling. To obtain a hard mass the fondant sugar is added directly to the drop sugar melt without dissolving in water, and the mass obtained may be cut into pieces and packed.  The starch flour may be mixed with the sugars before these are mixed together.  The sugars may be partly replaced by starch glucose.  The drop sugar may be prepared by melting sugar at 122 DEG  C., or by adding a small quantity of water and boiling down at 125 DEG  C. Examples are given.
