Each subsequent operation of the further switch TS 0  causes a succeeding one of the paths to be selected. The output points A n , A<SP>1</SP> 1 , A<SP>1</SP> 2  ... A<SP>1</SP> n  of the transistor switches T 1 , T<SP>1</SP> 1 ; T 2 , T<SP>1</SP> 2  ... T n , T<SP>1</SP> n  are connected to potentiometers (not shown) which determine the control signal derivable from a junction with a common impedance (not shown) in a similar manner to the known tuning arrangement (Fig. 1, not shown) disclosed in Specification 1,331,625. Operation of the further switch TS 0  causes a signal derived from C 1  to be applied to a point of common connection between a further common impedance R 3  and the plurality of paths so as to render an already on transistor pair T 1 , T<SP>1</SP> 1  off and the next transistor pair T 2 , T<SP>1</SP> 2  on. Control inputs E 1 -E n , E<SP>1</SP> 1 -E<SP>1</SP> n  receive signals such as generated by keys also for switching on the electronic switches. Mechanical or electronic switches may be connected in parallel to, or instead of the key switch TS 0  and may be remotely controlled. Remote control may be by cable or wireless. The circuit may be constructed by integrated circuit techniques and may be used for tuning control of radio or TV sets.

Title: A process for preparing elastic fabrics containing or consisting of polyester fibres
IPC: D06M13/52
Filed: 1965-06-28
Abstract: In a process for preparing elastic fabrics from fabrics consisting of or containing polyester fibres, the fabrics are stretched in either the warp or the weft direction and subjected whilst under the stretching tension to the action of a bath containing a swelling agent for the polyester fibres, e.g. a chlorinated aromatic hydrocarbon such as a chlorinated benzene, a phenol, an aromatic acid such as benzoic acid or salicylic acid, or an ester of an aromatic acid such as methyl salicylate, diethyl phthalate or dimethyl terephthalate.  The swelling agent is employed in the form of a solution or af an aqueous emulsion. The aqueous bath is preferably maintained at a temperature at or near its boiling point.  The impregnated fabric may be treated with saturated steam at about 100 to 120 DEG C.  The fabric may be dyed after treatment with the swelling agent by adding the dye to the same bath without the addition of a vehicle for the dye.  In an example, an unbleached fabric consisting of 76% of a polyester fibre and 24% of viscose rayon after treating under tension for 1 hour at the boiling point in a dilute aqueous emulsion of trichlorobenzene is dyed after the bath temperature has been reduced to 60 DEG C by adding to the bath 5% of a 50% paste of the dye C. I. Supplement: Disperse Blue 59 and the temperature of the bath is raised to the boiling point.  The dyed fabric is thereafter treated for 30 minutes with steam at 140 DEG C.

Title: Improvements in or relating to the production of hydraulic cements or binding agentsand the working up of the same in street and road construction
IPC: C04B40/00
Filed: 1933-10-04
Abstract: Portland or slag cement or like hydraulic material is hydrated with sufficient water, and under such conditions, e.g. agitation, that a pasty, gel-like mass is obtained; this is dried and ground and mixed with untreated cement for the production of concretes in which the ratio of tensile to compressive strength is about 1 : 6, and which can be rolled during setting.  The production of the gel can be facilitated by the use of hot water or steam, or by treatment with carbon dioxide or dilute mineral acids.  The gel may be ground with the cement clinker.  Fillers, setting-regulators such as plaster of Paris, and the like may be added, if desired, during the making of the gel.  As filler, cement clinker is suitable, and may be added to the top layer only in road making so as to break down gradually under traffic. According to an example, 50 parts of Portland cement are mixed with 50-100 parts of water until a gel-like paste is obtained. This is dried and ground and mixed with an equal quantity of Portland cement.  This is mixed with cement clinker in the proportion of 1 : 2.  After 28 days, a tensile strength of about 91 kg. and compressive strength of 475 kg. is obtained.

Title: Process for the recovery of saponins and sapogenins from vegetable matter
IPC: A61K36/8945
Filed: 1953-10-06
Abstract: In the recovery of saponins and sapogenins from saponin-bearing vegetable matter, the plant material is first comminuted (preferably to a pulp, the greater part of which is composed of particles of 8-200 mesh size), and the comminuted material is allowed to ferment in its natural state and in the absence of added inhibiting material until the content of extractable steroid material has markedly increased (e.g. for at least one day, preferably for substantially 5 days, at room temperature). The process is applicable particularly to the recovery of dioscin and diosgenin from roots of the family Dioscoreaceae, in which case the fermented material may subsequently be dried and extracted with a solvent for the steroid material. Examples illustrate the preferred application of the process. Specification 753,138 is referred to.
