Title: Apparatus for displaying illuminated advertisements or notices
IPC: G09G3/00
Filed: 1922-02-23
Abstract: 198,048. Nattero, G. Feb. 23, 1922. Monogrammic signs.-Apparatus for displaying illuminated advertisements &c. comprises panels a, Fig. 1, of electric lamps and a lamp-selecting device consisting of a number of wheels e each provided with spokes h, sectors &c. which carry contact pins 2 adapted to co-operate with contacts 3 on the frame b so as to bring about the selective illumination of the lamps on the rotation of the wheels in accordance with the arrangement of pins on the spokes. The wheels e are mounted on and insulated from the shaft c, each wheel consisting of a hub f and a rim g connected by the spokes h. The spokes and rims are made detachable from the hubs in order that the number of spokes may be varied, and the spokes are provided with detachable metal strips adapted to carry the pins. There is a set of contacts 3 on the inner side of the end wheels and a set on each side of the intermediate wheels., each set being connected to one section of the lamp panel. The wheels are electrically connected, and current is led in by leads 8 and brushes 9. The apparatus shown in Fig. 1 is adapted for intermittent rotation which is brought about by a motor control switch 26 operated by contacts 17 which, in turn, are operated by projections 13 adjustably mounted, at the end of the spokes, on the rim g of one of the wheels. When the wheels are rotated by the motor t, the pins 2 engage the contacts 3 and some of the lamps are illuminated. On further rotation, one of the projections 13 operates the lever 16, Fig. 3, and completes a circuit through the contacts 17 and the solenoid 25 of the motor control switch, which causes the core 29 to rise to allow the lever 31 to overbalance and break the motor circuit at the contacts 32, 33. The momentum of the armature is sufficient to turn the wheels e an amount which allows the projection 13 to release the lever 16 to break the circuit of the solenoid and allow the core 29 to descend under the control of a dash-pot. The expiring revolutions of the motor t are, however, insufficient to break connection between contacts 2, 3. At the end of the descent of the core 29, the pin 30 operates the lever 31 to close the motor circuit. The motor is thus restarted and the wheels e again revolve, engagement between the contacts 2, 3 being broken until the pins 2 on the next spoke come into action. Each contact 3 comprises a base 42, Fig. 4, secured to a block 4 on the support 4a and provided with a pivoted contact member 43 which is prevented from moving laterally by a sheath 45. The contact 43 is projected forwardly into the path of the pins 2 by a spring 48, and provides a long length of contact for the pins 2. Two modifications of the contact member are described, one of which is retained in its normal position by its weight, and is adapted for use where continuous running of the motor is desired. The contact members are capable of adjustment to vary the period of contact between them and the pins on the wheels.

Hoods.-Relates to hoods having the cant-rail connected to the rear pillar by links, so that it assumes a contracted position lying along the pillar when the hood is folded, and in which one of the links is connected to the rear stretcher bar, the joint of which is thus broken when the cantrail is lifted for folding. The cant-rail h is hinged at f<4>, i<2>, respectively to two links f, i which are hinged to the rear pillar c at f<3>, i<3>. The link f has an extension f<2> so that it forms a lever, and to this extension, and an extension e<3> of the stretcher bar e, is connected a link g. In the unfolded position, the pivot i<2> of the link : i lies above the line j joining the pivot f<4> of the link f and the pivot i<3> of the link i. Upon lifting the eant-rail h at its front end, it swings at first upon the pivot f<4> without movement of the link f. Further movement of the cant-rail causes the link f to move downwardly with the link i, thereby breaking the joint of the stretcher bar e to allow the pillar c to fall back about its hinge c<2>. The cant. rail takes up the position x with respect to the pillar in its completely-folded position. Reference has been directed by the Comptroller to Specifications 19019/12 and 0557/13.

Title: Vegetable based milk substitute
Inventor: FRANKLIN HUGH BELGROVE
IPC: A23C11/10
Filed: 1961-02-15
Abstract: In preparing a milk substitute, non-woody plant material, e.g cabbage leaves, is macerated, with water if necessary, and the resultant pulp filtered, preferably after agitation with decolourizing carbon, to produce a filtrate from which the protein is precipitated, e.g. by heating to 55 DEG  to 90 DEG  C., and decanted or centrifuged out to yield a slurry which is converted to a colloidal dispersion, e.g. using a colloid mill.  The colloidal dispersion, which may also be prepared by vacuum evaporating the filtrate at or below 30 DEG  C., is then blended with an aqueous emulsion of a vegetable fat, e.g. maize oil, containing 2 to 5% by weight, of fat, a small amount of soya lecithin as emulsifier, and, if desired 3 to 5% of unrefined sugar, to produce an emulsion, preferably of droplet size 5 to 20 m , to which further additions, e.g. of vitamins and/or mineral supplements, may be made.  The milk-substitute emulsion may be dried, condensed or converted to cheese or yoghurt.  A modification of the process comprises adding live yeast to the precipitated and separated protein slurry, autolysing, e.g. at 50 DEG  to 55 DEG  C. for 24 hours, separating the liquid (now containing hydrolysed protein) from the resultant mixture, adding to this liquid an amount of separated protein substantially equal to the hydrolysed protein it contains, and then blending the resultant suspension with an aqueous emulsion of a vegetable fat.
