When loose slips are used these are stored in rows of pockets 10-13, one row for each suit. In studying a game or solving a problem, the user, having set up the hands in the outer boards, successively withdraws the slips of each trick by means of tweezers and places them in the pockets of the central board. Recording sheets which may be assembled in the form of a pad may be provided for enabling a permanent record of the solution to be kept. A marking board may be provided comprising two pointers indicating the scores up to thirty each and two number discs for the contract (tricks bid and suit). In a modified device, in addition to a central and outer boards, thirteen small supplementary boards are arranged on the device so that as play proceeds suitably marked counters may be placed on the supplementary boards in turn to register the cards played in each trick.

Title: Manufacture of thin walled plastics material articles
IPC: B29C35/06
Filed: 1974-10-03
Abstract: The process and the apparatus provide for starting from a strip or sheet which is continuous, of plastic material, which is first of all heated by infrared heating means (36) and then passed in contact with three heated rollers (30, 34, 32), to achieve a uniform distribution of the temperature both above and below said strip, after which, in the hot condition, said strip stops and is indexed towards a thermoforming machine (not shown), in which the articles are formed during the stops due to said indexing. This process avoids the disadvantages of the conventional infrared heating methods with which a uniform distribution of the temperature is not achieved. <IMAGE>
