IPC: B65D49/06
Abstract: 109,440. Smith, A. C. Sept. 6, 1916, [Contiention date]. Bottles, non-refillable. - Relates to bottles of the kind in which a pivoted valve is mounted by spring catches which enter recesses in the bottle neck and provided w i t h gravity - controlled means for closing it when the bottle is returned to the vertical position. The valve is anchored in the bottle neck 1 by a pair of spring- pressed pins 22, which are slidably mounted in a transverse sleeve 13 on the under side of the stationary section 7 of the valve and engage in sockets 4 at the inner ends of longitudinal grooves 3 in the bottle neck. The section 7 of the valve is larger than the hinged section 8 and rests on a shoulder 5 in the bottle neck. A transverse shoulder 14 on the upper side of the section 7 limits the upward movement of the section 8. A balance-pin 17, the end 18 of which is heavier than the opposite pointed end 19, is pivoted to ears 15 on the under side of the movable section 8 and returns this section to the closed position, the end 19 of the pin engaging in a recess 6 in the bottle neck but being received in a notch 20 in the edge of the section 8 while the valve is being inserted. The bottle is formed with a lip 2 at its mouth.

Patent GB-200902-A (GB)
Title: Process of manufacturing cyanides
IPC: C01C3/00
Filed: 1922-04-19
Abstract: Alkali cyanides are obtained by reacting with nitrogen, which may be under pressure, upon a mixture of an alkali compound such as sodium carbonate, and carbon obtained from the matter dissolved by alkali from wood or other fibrous vegetable matter, in the presence of a metal catalyst such as iron or iron oxide and if desired an alkali halide such as sodium chloride or fluoride.  The carbon used is obtained by incinerating the "black liquor" obtained in cellulose manufacture, and washing out the sodium carbonate remaining.  The heating of the solid residue of the black liquor may be effected in a retort at a comparatively low temperature, below 550 DEG  C. preferably 200-350 DEG  C. to obtain a high yield; or the concentrated liquor may be mixed with the catalysts and evaporated to dryness to obtain a suitable charge for the cyanide reaction.  The nitrogen may be supplied in the form of producer gas, but in that case the retort is sealed after the reaction and only opened when cold to avoid the presence of carbon dioxide with the cyanide during cooling.  An increase in yield may be obtained by adding a second portion of charge to the retort when its original charge has shrunk owing to the progress of the reaction and then continuing the reaction for the same or a little longer time than the original charge would have taken.

Title: Shampoo leaves and a method of producing the same
Inventor: HEATON JOHN EVERETT
IPC: C11D1/00
Filed: 1955-04-18
Abstract: A shampoo leaf comprises a sheet of paper of high wet strength, suitably a vegetable parchment paper, which carries on one or both faces a surface coating of a non-saponaceous detergent, such as sodium lauryl sulphate, which adheres to the paper without flaking off, the shampoo leaf being such that it can be rubbed on to a user's head without the paper disintegrating.  Preferably the leaf has a hole towards one end so that a finger may be inserted to give a grip when the leaf is being used.  In a modification two sheets, each coated on both faces, are stuck together face to face, each sheet having small perforations out of register with those of the other sheet, the perforations serving to allow the passage of the detergent from between the sheets when in use.  The leaves may be made by coating the paper with detergent, drying the coated paper in a tunnel drier and, if desired, pressing or crimping two sheets together while still tacky to make them adhere.  In the case of single leaf shampoos the drying may also be performed by an infra-red treatment. After drying, the sheets are cut into suitable sizes and shapes, and several may be fastened together in a holder.  The first Provisional Specification refers to shampoo leaves as described above which are coated with soap.

Abstract: 272,020. English Electric Co., Ltd., and Bolton, R. A. R. May 7, 1926. Switching systems.-A rotary converter, transformer &c. 1 supplying a circuit 2, is relieved of a 20 to 100 per cent overload when hot by the switching in of an additional machine, by the inclusion of a resistance in the load circuit, or by the switching out of the machine itself. A current transformer 4 supplies a liquid thermal device 6, having characteristic similar to the machine, so that, when' the machine heats up, a member 14 rises, firstly compressing a, spring 37 and thereafter releasing a, pivoted catch 29, so that a contact 25 is moved to bridge fixed contacts 9. Similarly, when the device cools down, the member 14 is forced down by a spring 41; spring 38 and catch 30 functioning to give a quick break. An overload relay 8 is included in series with the contacts 9 in the current 10, so that only upon the occurrence of a predetermined overload when the machine is hot, is the circuit 10 completed to cause the starting up of another machine, or the inclusion of a resistance in the circuit 2. Undue heating causes the switch 26 to open, to effect the shutting down of the machine 1. Excessive overloads, such as due to short circuits, are dealt with by another overload device 'having an high setting.

Tell-tale apparatus.-Apparatus for reproducing movements of a small power device such as a gyroscopic compass, comprises a relay device which operates a transmitter to control receiving apparatus such as repeating compass cards. The transmitter is operated by a rotatable disc 2 upon which is mounted a compass 6 and relay apparatus A, B. The relay apparatus comprises a voltage regulator A and a three-phase motor B. The gyroscope 6 carries on an arm 4 a set of three brushes 21, 22, 23 traversing an arc of contacts 20 connected to a set of stationary brushes 19 on the commutator of the regulator A, which, as shown comprises a motor supplied from the mains 27. Leads c<1>, c<2>, c<3> connect the gyroscope brushes to the slip-rings of the motor stator 28, the rotor being' supplied from the mains 27. When the gyroscope swings, the brushes 21, 22, 23 move to points of different potential and displace the resultant field of the stator to cause the rotation of the rotor 24 through a corresponding angle. The rotor 24 is geared to a stationary ring 1, and when displaced causes the rotation of the disc 2 and the operation of the repeating transmitter. Rotation of the disc 2 moves the originally engaged segments 20 into contact with the brushes 21, 22, 23 and the potentials of these segments are modified -in accordance with the new position of the rotor 24 by the adjustment of movable pairs of brushes 15, 16 and 17, 18' which supply the field and armature of the regulator A respectively. The pairs of brushes are geared to the ring 1 by a pinion 14 and are arranged to produce magnetic fluxes at right angles. Instead of a motor, a dynamo may be used as a regulator. In a modification, the pair of brushes 15, 16 and 17, 18 are fixed and the brushes 19 are adjustable by the pinion 14.
