Title: Electronic push button combination lock
IPC: G07C9/00
Filed: 1974-04-04
Abstract: 1404748 Electronic locks INTEGRATED CONVERSION TECHNOLOGY Inc 4 April 1974 [6 April 1973] 14943/74 Heading E2A An electronic push-button combination lock comprises push buttons corresponding to different digits 0-9, and connected to a decimal to binary converter 11 which provides an output binary signal in response to depression of a selected button which signal defines the first input signal of a comparator circuit 12 which receives a further, coded binary signal input from coded circuits 14-17, and which is connected to a ring counter 18 having a number of stages one greater than the number of coded circuits, the comparator generating an advance signal to the counter to advance it to a next successive stage whenever the output binary signal corresponds to the coded binary signal whereby the lock 20 is opened when the last stage is reached to provide an unlocking signal thereto. The lock will not open unless the correct sequence of push buttons are depressed to provide successive output binary signals which correspond to the successive coded binary signals. If a button is wrongly depressed comparator 12 generates a reset signal 22 to restore the ring counter 18 to its start position. A timer 23 is energised upon the counter reaching its final stage which automatically resets the counter to its first stage after a given period. In the embodiment shown a single lock is applied to a door. In a modification several door locks may be provided and the coded binary signals for each door may be altered from a remote location. Each lock includes an address multiple bit shift register Fig. 3 (not shown) for effecting a serial to parallel conversion of successive bits of address information the output of which forms one input of an address comparator, the second input of which is an address code identifying the particular lock. The address code is represented by a series of address pulses from an address signal line means connected to the serial input of the address multiple bit shift register. A gate connected between a data signal line means providing a series of coded pulses representing new codes to be inserted into the lock and a code insert multiple bit shift register is controlled by an open gate signal from the address comparator to open and permit a new code to be inserted. This open gate signal is only generated when the address code supplied by the address signal line means corresponds with the address code identifying the particular lock.

Abstract: 614,451. Snap-action switches. ETABLISSEMENTS LABINAL. May 17, 1946, No. 14995. Convention date, May 7, 1945. [Class 38 (v)] A snap-action mechanism for a switch comprises a cam-piece 1 carrying contacts 7 and having working positions corresponding to notches 1<1> which are engaged by rollers 2 biassed by springs R; spring means r transmitting driving force to the cam-piece 1. A push-rod 12, Fig. 2, moves through a distance a<12> to compress the spring r and then through a distance a<1>, positively forcing the rollers 2 out of the notches so that the spring r may snap the cam-piece to the next working position engaging brush contacts 6. As applied to a rotary switch, Fig. 3, a rectangular part 13 of the operating shaft is engaged on both sides by leaf springs r which are secured to a frame 15 rigid with the cam 1. Rotation of the operating shaft through an angle a<12> stresses the springs r, but the cam is not rotated thereby until it has been positively rotated through an angle a<1> by the part 13 bearing on an internal face a. The invention overcomes disadvantages of symmetrical lobe cams wherein snap-action only takes place when the cam 1 is half-way between working positions.

Abstract: 515,015. Mercaptoarylthiazoles. UNITED STATES RUBBER PRODUCTS, Inc. May 20, 1938, No. 15073, Convention date, May 27, 1937...[Class 2 (iii)] Mercapto-aryl-thiazoles are prepared by reacting a preformed metallic salt of trithiocarbonic acid with an ortho-amino thiophenol or with an o-o<1>-diaminodiaryldisulphide which latter compound may be used either in a pure form or in the crude state as it is obtained by the heating together of an aryl amine and sulphur. The formation of the mercapto-arylthiazole is stated to take place quantitatively by boiling the reactants together in alcohol for one hour. If desired, when the o-o'-diaminodiphenyldisulphide prepared as above is used, it may be purified by steam distillation to remove unchanged aniline, followed by solution in dilute hydrochloric acid and filtration to remove unchanged sulphur. The alkali trithiocarbonate may be prepared by treating an alkali sulphide with carbon disulphide. In examples (1) carbon disulphide is added to an alcoholic solution of sodium sulphide and to the trithiocarbonate solution thus formed o-o<1>- diaminodiphenyldisulphide is added and the mixture boiled under reflux for one hour to give 1-mercaptobenzothiazole. (2) Carbon disulphide is stirred into an aqueous solution of sodium sulphide, o-o<1>-diaminodiphenyldisulphide is added, and the mixture refluxed for 24 hours, to give 1-mercaptobenzothiazole. Other disulphides mentioned which may be used include 2-2<1>-diamino-5 : 51-dimethyl-diphenyldisulphide, and o-aminothiophenols such as 2-mercapto-3-aminotoluene.
