Title: Improvements in and relating to electric switch mechanisms
IPC: H01H17/00
Filed: 1953-12-15
Abstract: 781,971. Retractive switches. McINTOSH, J. S., and WORBOYS, F. A. Dec. 14, 1954 [Dec. 15, 1953; July 20, 1954], Nos. 34900/53 and 21138/54. Class 38 (5). [Also in Group XXXVIII] The circuit of a stop lamp on a bicycle or like vehicle is closed by a switch comprising two members mounted on the brake-operating rod or wire which passes therethrough. In the case of wire-operated brakes the outer sheath 8 (Fig. 1) terminates in a cylindrical sleeve member 12 making a sliding fit in the body 9 which has a nipple 10 for insertion in a slot 11 in the bracket 5 carrying brake lever 6. A conductive clip 16 connected in the stop lamp circuit is fitted to the insulated sheath 8 and a spring inside the body 9 urges sleeve 12 outwards to ensure that clip 16 does not normally contact the body 9. When the lever 6 is operated to pull wire 7, the initial movement causes the sheath 8 to be pulled towards the bracket 5, whereupon sleeve 12 enters the body 9 compressing the spring into a hollow. Clip 16 contacts body 9 to light the stop lamp. Further movement of lever 6 moves wire 7 relative to sheath 8 to operate the brake in the normal manner. If the sheath 8 has not got an insulating cover an insulating member is provided to carry the contact (Fig. 3, not shown). In the case of roller lever rod-operated brakes (Fig. 5) the lever L lifts the frame 19 and hence insulator 17 carrying contact 18 which connects with the body 9, after spring 15 is compressed, to light the stop lamp. Further movement lifts body 9 and hence the pull-rod P which is connected thereto but which is a sliding fit within insulator 17 ; the brake is thus operated after the initial movement has caused the stop lamp to light.

Title: Dispensing system responsive to scrambled coded data on a document
IPC: G06Q40/02
Filed: 1971-07-28
Abstract: 1353629 Currency dispensers DOCUTEL CORP 28 July 1971 [29 July 1970] 35405/71 Heading G4X In a credit-card controlled dispensing system, particularly for dispensing currency, scrambled data read from a presented card is unscrambled and compared with data stored in the system to check the validity of the card, updated data is desired to reflect the dispensing transaction, the updated data being scrambled and written on the card. In the embodiment described the card carries magnetically recorded data including a customer identification code, expiry date, total number of permissible uses remaining, allowed number of uses per day, date last used and number of times used per day. Also written on the card at predetermined locations are parts of an unscrambling key. On insertion of the card and manual entry of the identification data via a keyboard (three attempts allowed) the system determines the whole unscrambling key from the parts written on the card and the manually entered identification code and unscrambles the written data. The unscrambling method includes four steps: transposition of characters from the order as read, substitution of new characters for the characters as read, transposition of words from the order as read and removal of extraneous characters. If the unscrambled data indicates that the card is being used by the proper owner, and that the card has not expired or been used too many times either since issue or on that particular day, the customer is instructed to select one of two values of currency packets which are delivered to him together with a printed receipt of the transaction. The data read from the card is updated to take account of the transaction and is then rescrambled in accordance with a scrambling key determined by the system logic and the entered identification code. The rescrambled data is therefore in a different arrangement to the scrambled data as originally read and in this way the data written on the card changes at each use making the system code difficult to break. If for any reason the card is found invalid or the manual entry of necessary data is not performed within preset time limits the card is captured by the system and a receipt given. The system is provided with error counters which count the number of successive times that errors are detected at certain stages in the transaction. If any of these counters reaches a preset limit the system terminates the present transaction and then shuts down. Specification 1,353,630 is referred to.
