Abstract: 371,453. Road-traffic signals on vehicles. THIMBLETHORPE, W. S., 42, Jermyn Street, Piccadilly, London. Jan. 24, 1931, No. 2364. [Class 118 (ii).] Red, yellow and green lights 18, 19, 20 are selectively displayed to the front and rear from casings 13, 14 arranged one on either side of a road vehicle, the switch system being such that first the yellow cautioning signal is lighted, and then the red signal on the side to which the vehicle is about to turn, the green " go " signal being simultaneously ing illuminated on the other side of the vehicle. The red signal, and, if desired, the green signal also, may be intermittently flashed. A delay-action device may cut out the signals after a predetermined time. A single switch handle 22 may be moved to display simultaneously on opposite sides of the vehicle either a green and a red light, or a green and a yellow light, or two green lights, or two yellow lights. The signal units 13, 14 are fitted with cowls and may be miniature replicas of the standard stationary road-traffic control signals, or the lights in each unit may be arranged in a horizontal line. Extra lenses or lenses extending partially or wholly round the unit may be used to give an all-round view of the signals. The switchhandle 22 is first rotated to a selected position, and then moved axially. The intermittent flickering of the lamps is caused by an interrupter switch operated by the movement of the spindle of the handle 22. The complete control switch forms the subject-matter of Specification 371,595.

Filed: 1966-01-19
Abstract: The invention comprises linear fibre-forming modified poly-e -caprolactams having up to 135 milligram equivalents of end groups, up to 20 of which are primary amino, the remainder being carboxyl, the logarithm of the Brabender melt viscosity of the polycaprolactam being not more than 1.017 + 6 x 10-5 M, where M is the number average M.W. and is at least 15,000. It may be produced by heating at 240-290 DEG  C. a molten mixture of e -caprolactam and 0.1-0.7 mole per cent of a C6- 20 dicarboxylic acid and stirring the mixture whilst its surface is swept with an inert gas at a flow rate of at least twice the volume of the mixture per hr. Alternatively the mixture may be heated under reduced pressure or solid state polymerization may be effected.  A copolyamide may be produced. Dicarboxylic acids specified are aliphatic, heteroaliphatic, alicyclic and aromatic non-volatile acids which may contain substituent groups.  They include sebacic, pimelic, suberic, azelaic, adipic, undecanedioic, dodecanedioic, tridecanedioic, tetradecanedioic, terephthalic, bibenzoic, phthalic and naphthalene-2,7-dicarboxylic acids.  The use of acetic, succinic and glutaric acids is also disclosed.  The acids may be replaced by their mono- or diesters or anhydrides. The polymerization may be batch-wise or continuous and may be catalysed by the presence of water.  Additives, optionally as concentrates in the monomer or polyamide may be introduced at any stage of the polymerization. If corrosive, they may be added at the centre of the polymerization mixture by means of a non-corroding tube and then dispersed outward.  Additives specified are flame retardants, e.g. Sb, P and halogen compounds, TiO2 as a delustrant, antistatic agents, adhesion promoting compounds, e.g. isocyanates and epoxides, heat and light stabilizers, e.g. ionic reducing compounds, ionic compounds of manganese, copper and tin, phosphites, alkylated aromatic amines, and ketone/aromatic amine condensates, pigments, e.g. 2, 9-dimethylquinacridone and inorganic pigments, fluorescent agents, brighteners, cross-linking agents, bacteriocides, e.g. phenol and quaternary amines, colloidal reinforcing particles, antisoiling agents, and other polymers, e.g. polyethylene terephthalate.  In typical Example (1) the reaction is carried out initially under a superatmospheric steam pressure which is later reduced to atmospheric pressure and then replaced by a current of nitrogen.

Title: Speed control for fans used in the regulation of boilers and for like purposes
IPC: F23L1/00
Filed: 1946-01-28
Abstract: 607,168. Regulating fans. O'BREEN, J. E., SCHIPPERS, J. F., and GORDON & CO., Ltd., J. Jan. 28, 1946, No. 2735. [Class 110 (i)] [Also in Group XXXVII] In an arrangement, particularly for boiler furnaces, wherein the speed of a fan is changed from a high to a low value in accordance with the position of a damper, the change from high to low speed is effected by a regulator including a pneumatic relay and lost-motion mechanism providing a time-lag to prevent hunting. If the fan is running at high speed and the damper moves towards the closed position, the cam 12, Fig. 4, is rotated to lift the supply and release valve 40 and compressed air flows through the pipe 44 to close valve 35. The small diameter pipe 45 admits compressed air to a vessel 43 through a pipe 46, and when the pressure builds up sufficiently to overcome the resistance of an adjustable spring 37, the rocker arm 28 operates the switch 31 to effect change to low speed. If the damper moves away from the closed position before the change-over is effected, the cam 12 operates to allow the valve 40 to shut off the compressed air supply and release the air in pipe 44. Valve 35 then opens to release the air in vessel 43 and the switch 31 is not operated. The damper is controlled automatically in accordance with the load on the boiler, and its operating gear includes an oscillating lever coupled to a shaft 2, Fig. 1, of the fan regulator. Keyed to the shaft are discs 8, 9 carrying pairs 10, 11 respectively of adjustably spaced members adapted to co-operate with pins 16, 17 on cams 12, 13 for actuating rocker arms 27, 29 to operate the compressed air valve 40, and the high-speed fan switch respectively. The spacing of the members of each pair 10, 11 provides for lost-motion to assist in preventing hunting. The rocker-arms 27, 28, 29 are mounted on a shaft 26 which also carries a rocker-arm 30 adapted to be actuated on starting, when the damper is closed, by an arm 22 on the shaft 2, to close a switch in tha starter relay circuit.
