Title: Improvements in and relating to combination or permutation locks
IPC: E05B37/02
Filed: 1920-04-20
Abstract: 166,694. Valente, A., and Curzon, M. April 20, 1920. Locks, permutation; padlocks.-The shackle h of a padlock is held in the locked position by a bolt a, upon which are lugs d, d<1>. &c. co-operating with notched setting discs b, b<1>, &c., mounted on the bolt, each having a spring- pressed detent k, k<1>, &c. Indentation l on the edges of the discs act with the detents to produce clicks or impacts when revolved, and one indentation z is shaped to limit revolution in one direction, on engaging the detent, but not in the reverse direction. The detents are retained in the casing when the discs are removed, by shoulders. The lugs d, d', &c. may be mounted in sleeves s, s<1>, &c. on the bolt a, as shown in Fig. 3, allowing them to be turned to change the combination, and secured in position by a screw t. To operate the padlock, the discs are turned in the direction of their limited rotation as far as possible, and then in the reverse direction through a certain number of clicks. This brings the notches c opposite the lugs d, and the bolt a can be withdrawn to release the shackle h. In a modification, the bolt a may have inclines or recesses to operate the spring catches of a bag fastening.

Title: A teleprinter reception system for simultaneously transmitted code elements
IPC: H04L27/26
Filed: 1958-04-08
Abstract: 857,006. Type-printing telegraphy. TESLA NARODNI PODNIK April 8, 1958 [April 5, 1957], No. 11050/58. Class 40(3). Combinations of current impulses received simultaneously over separate channels operate relays PR1-PR5 to prepare holding circuits at contacts pr1-pr5 for combination relays KR1- KR5, the combination relays all being initially operated in response to a preceding start impulse by a contact AN and held over circuits including contacts Kr1-Kr5 and a common contact PK which is changed over briefly at the mid point of the current impulses so as to release the relays except where they are held operated by contacts pr1-pr5. In this manner the combination of current impulses is registered on the combination relays and controls a printing or perforating action via contacts Kr6-Kr10 The actual operation is initiated by a contact AS which is closed at the termination of the current impulses during a stop interval. Contacts AN, PK and AS are operated by a cam system which is normally held stationary but is released by the start impulse which operates a relay Str and at contact Str1 releases an electromagnet SM controlling a friction clutch. The current impulses may be transmitted either over separate lines or over separate channels on a single line or radio transmission path.

Filed: 1977-03-17
Abstract: 1536982 Electronic alarm watches DAINI SEIKOSHA KK 17 March 1977 [19 March 1976] 11384/77 Heading G3T In an electronic alarm timepiece, an analogue time display is given by hands driven by a stepping motor, and pre-set alarm time is displayed in a window W Fig. la (not shown) in digital form by numbered discs. When a stem is pulled out the timepiece is stopped and rotation thereof in one or the other direction moves the hours or minutes hands respectively.  To set the alarm time, the stem is pushed in. When rotated in one or the other direction it moves the hours disc or the minutes disc respectively. Each disc carries a ring of numbers and a corresponding ring of magnetic inserts 17a, 17b, Fig. 1c. A respective Hall element 16a, 16b is fixed adjacent each disc and the number of pulses produced thereby is a measure of the extent of movement of the respective disc. The Hall elements (16a, 16b) Fig. 1c are represented by switches Sa, Sb respectively, in Fig. 2 and the pulses therefrom are used to set an alarm time into the hours counter M24HC and minutes counter M60MC respectively. In Fig. 2, a crystal controlled oscillator 21 is followed by a frequency divider 22 having a 1Hz output to a motor drive circuit 23. The 1Hz signal is also fed to seconds, minutes and hours timekeeping counters 24, the contents of which are compared in a circuit 26 with a pre-set alarm time stored in counters 25. Coincidence results in an AND gate A2 passing a control signal to an A.F. oscillator to sound an alarm. The alarm oscillator may also be actuated for testing, by closing a switch Sd. A 12 hour or 24 hour clock system may be employed.
