NEW IDEAS

DISPLAY OF INTENTIONS

FIRST PRIZE TO AUSTRIAN

(From "The Post's" Representative) LONDON, October 12.

Every year the Institute of Patentees li holds an exhibition of inventions at the Central Hall, Westminster. Pat- j? entees are an optimistic group of human beings, and they display their work or s a description of their work in the hope ° that some one or some firm will see r the advantage of spending, money, to + put the articles on the market. Such is the incredulity of human nature that very few of the inventions are heard of again, and those which are *: obviously of merit are developed only c after years of hard work and can- f vassing. Possibly, inventors who turn out new articles which eventually * bring them a profit have no need to display them at a public exhibition. The show, however, is always inter- , esting, and there are certainly a few c of the exhibits which the public will . hear of again. Medals have been awarded. The first prize goes to Herr c Rudolf Stelzhammer, of Barnabietngasse, Vienna, who has invented a ? pipeless radio organ. He claims that 1 its sound would fill St. Paui's Cath- E edral clearly, and yet is equally adapt- £ able to the smallest room. An ordinary x organ producing the same notes would ; cost £1500. It is claimed the new J type can be built from £50 upwards. s The notes are certainly clear, and the '<■ volume seems unlimited. I Second prize goes to an invention 1 for a machine which produces an ac- £ curate model of a person or object in I sculpture form from a photographic t record. The inventor is Mr. S. T. 1 Jeffreys, of Bushey, Herts. ] The third prize goes to Mr. J. D. ; Furey, of Dublin, who has invented ; a perambulator with wheels which ( swivel like the front wheels of a car j as pressure is placed in a lateral direc- ; tion on the handle. , HIGH VISION CAR. Saloon motor-cars have their dis- ! advantages, as it is difficult to observe things on a high level. The high vision car obviates this difficulty by ' carrying the glass of the doors and the 1 panels upwards into the margins of ' the roof. . ' There is some logic in the- new 1 Savile Row dress waistcoat. As a ' matter of fact, it is not a waistcoat at : all, but an expanding band fastened by ' a buckle and with buttons in front : that do not button and pockets which i do not open. Some one is always devising some new attribute to safety razors. This '< time it is a ridge of rubber beside the blade which stretches the skin before the blade passes over the face. A safety electric kettle tips up and ejects the electric plug when the water boils away beyond a certain point. When the water is thus dangerously low the centre of gravity of the kettle is altered and one side is lowered, actuating a trigger which releases the plug. A new type of propeller has slots through the blades. The water forced through the slots condenses all the air on the surface of the blade and stops vibrations. NEW TYPE OF BICYCLE. Bicycles have been stabilised how for many years, but one inventor thinks an improvement can be made by making the action after that of rowing. The seat is low with a back rest and the feet are shot forward either together or alternately, as the rider desires, his efforts actuating the front wheel and not the back. Some one has thought it necessary to invent a cigarette with a detachable tip. so that the smoker who objects to tips can pull it off. There is a sleeping cap which has curlers attached to it. A packing case or a travelling trunk is made to collapse readily. It is rigid when it is put together, and the act of raising the ends automatically locks the case. The sparklet originally used for making soda water is applied to a selfinflating lifebelt. An .indiarubbcr tube lies deflated beneath a person's coat, but it is rapidly inflated by pressing a gadget. This pierces two sparklets which, in their turn, inflate the tube. It is suggested that these life-savers should be worn by yachtsmen and sailors in stormy weather, or by swimmers. There are hundreds of other contrivances which apply to almost every form of human activity.

Of the cities outside London. Liverpool spends most on its police, while Birmingham's fire brigade is the most costiy.
