Title: Method of and apparatus for producing tickets
IPC: G06Q30/00
Filed: 1971-10-22
Abstract: 1339187 Ticket printing LICENTIA PATENT-VERWALTUNGS GmbH 22 Oct 1971 [24 Oct 1970] 49223/71 Heading G4T To initiate the printing of a particular public transport destination on a ticket, one or more initial letters of the destination are entered on a keyboard which is linked to a programmed computer, the computer then causes the visual display of one or more complete destinations (including the particular destination) having these one or more initial letters and of code numbers corresponding to the respective displayed complete destinations, and the subsequent entry via the keyboard of the code number corresponding to the particular destination conditions a printer for printing the particular destination. The keying in of all of the letters of the particular destination is thus unnecessary. When used for the printing of railway tickets, the computer may be programmed so that the system functions as follows. On keying in the first letter of the destination required, the computer causes the display of the most commonly requested destinations (and their code numbers) beginning with that letter. If one of these displayed destinations is the destination required, then entry of the corresponding code number conditions the printer accordingly. If the required destination is not displayed after entry of the first letter, then the second letter is keyed in, whereupon the display is cleared of the most commonly requested destinations and other destinations, beginning with the first and second entered letters and possibly only the most commonly requested which begin with these two letters, are displayed. The operator continues keying in letters until the destination required is displayed, successive displays including progressively less commonly requested destinations and no display including a destination included in an earlier display. The keyboard includes a start key, a complete set of alphanumeric keys, a release key and keys for setting up the date and the class of ticket. After entry of the destination, date and ticket class, the computer may cause the display of the complete ticket data and the operator, after checking this display, operates the release key to cause printout. A number of keyboard/display/printer units may be connected to one computer. Operation of the start key may send a signal to the computer identifying the particular unit.

Abstract: 1307209 Toaster PHILIPS GLOIELAMPEN FABRIEKEN N V 1 Nov 1971 [4 Nov 1970] 50642/71 Heading A4D [Also in Division G1] A toaster makes use of a thermosensitive element comprising a resiliently bent rod 3 connected at its ends to a thin strip or wire 4 which is, therefore, under stress. The strip of wire 4 has a high thermal co-efficient of expansion relative to the rod 3 and, because of its low mass, a low thermal capacity. The element thus reacts rapidly to a temperature change. One end of the element is fixed to a wall of a toaster, the other end 6 being free to move. On increase in temperature the end 6 moves upwardly thereby releasing a locking device 2. A hook end 10 Fig.2, is disengaged thereby enabling a drawspring 15 to disengage a hook 17 from an arm 16, which is connected to springs 8, thereby popping up the toast. A pointer, pivoted at axle 23, continually registers on a scale 26 the progress of the toasting. The end 5 is fixed, via a rigid binietal element, by a screw bolt turned by a knob thereby allowing fire control of the toasting. Axial displacement of the knob directly engages the rigid element causing end 6 to move upwardly and terminate toasting. The thermosensitive element may be used to control central heating systems or the temperature of electric irons.

Abstract: 1,087,777. Artificial teeth. E. KOPP. Dec. 8, 1965 [Dec. 17, 1964], No. 52068/65. Heading A5R. [Also in Division B5] A pattern of a tooth stump or jaw part for use in making dental prostheses is cast from a synthetic plastic film or plate by drawing the film or plate over a model of the part. Apparatus for casting the pattern comprises a heating means and a pressing device arranged so that they may be brought to act alternately on the film or plate, which is supported so that it is vertically displaceable relative to the model. The model, e.g. in the form of a tooth stump, is supported by a kneadable composition (21) in a trough 3 on a table 2. The film is clamped in a frame 7 which is vertically displaceable, against springs 18, above the model. A radiant heating device 14 and a blowing head 17 are supported by arms 13, 22 extending from a head being rotatable relative to a column 11 so that either the heating device or the blowing head may be disposed above the frame 7. In operation, the film is plasticised by the heating device. The blowing head is then lowered against a spring by a piston or diaphragm operated by compressed air, to carry the frame 7 downwardly until the film is stretched by the model. Compressed air applied by the blowing head presses the film into intimate contact with the model.: In order to compensate for the strinkage of the pattern as it cools, a compensating film is placed on the side of the pattern film facing the model so that it is moulded with it. The moulded compensating film is removed from the pattern. The pattern is made of a material which will burn away in a casting mould, e.g. polymethacrylates or polyolefins.
