Title: Locks for doors
IPC: E05B63/00
Filed: 1957-06-19
Abstract: 831,446. Locks; sliding bolts. LEGGE & CO. Ltd.. J., LEGGE, W. H., and PENNINGS, B. May 23, 1958 [June 19, 1957], No. 19252/57. Class 44 A door lock having a dead bolt 10 operable either by a key from one side of the door, or by a turn knob 23 from the other side, is characterized in that means operable by the key are provided for dead-locking the bolt in its locking position after the key has shot out the bolt into the locking position and in completing a full revolution to enable it to be resumed. The bolt 10, having a head guided in a hole in the front end of a lock casing 12 and a lath 13 with a key notch 14 and a talon 15, is guided on a stump 16 fixed to the casing 12. The stump 16 projects through a guide slot 17 (in the lath 13) and into a gating 18 in a security lever 19 which is urged downwardly by a leaf spring 21 and is pivoted at 20 to the bolt lath 13. The turn 23, on the inside of the door, carries a camdisc 24 with a V-notch 25 engaged by a peg 26 on the security lever 19. A deadlocking means for the bolt comprises a bell-crank lever 30 which is pivoted, at 31, to the casing 12 below the bolt 10 and has, on its rear face, a cam surface with abutments 33, 34. Rotation of the turn 23 in the bolt shooting direction, with the bellcrank lever 30 in the inoperative position, first causes the cam-disc 24, co-operating with the peg 26, to raise the security lever 19 so that the grating 18 is freed from the stump 16. While maintaining the security lever raised the cam-disc 24 shoots the bolt into its locking position and finally allows the security lever 19 to lower so that the rear pocket of its gating 18 embraces the stump 16. The sequence of operation in reverse takes place if the turn 23 is rotated in the opposit direction. For operating the bolt from the outer side of the door the closure plate side of the casing 12 rotatably receives, a crank-disc 27 which is mounted coaxially with the turn 23 and has a pin 28 which co-operates with the underside of the security lever 19 and with the notch 14. The crank-disc 27 has a central slotted thimble 29 adapted to be engaged, and driven, by the connecting bar, not shown, of the key-operable plug of a cylinder lock. After the crank-pin 28 has moved the bolt into the fully shot position, and with continued rotation, it engages the cam abutment 34 and trips the bell-crank lever 30 so that its forward edge engages in a V-notch 32 in the lath 13 to dead-lock the bolt 10. Release of the dead-locking means can be effected only by reverse operation of the crank-disc 27 the pin 28, in this case, engaging the'cam abutment 33 to trip the bell-crank lever 30 into its inoperative position. Operation of the turn 23 does not dead-lock the bolt, however a bolt shot by the turn can be unlocked either by the turn or, by the key-operated crank disc. The bell-crank lever 19 carries a spring-loaded plunger 36 which co-operates with the cap side of the closure plate of the casing 12.

Filed: 1959-06-09
Abstract: 858,329. Cinematograph cameras. AGFA A. G. June 9, 1959 [July 1, 1958], No. 19788/59. Class 97(1) A cine-camera for use with or without a spool box comprises means responsive to the radius of the coil of film on a supply spool and adapted to operate a switch-off device for the filmadvancing mechanism when said radius is reduced to a pre-determined ratio, the responsive means being provided on a detachable member that is also insertable into a spool box for use in the same camera. As shown in Fig. 1 a spool box 1 having openings 3 for the spool spindles has removably mounted therein a member 13 having an arm 19 pivoted thereon at 20, this arm being spring biased so as to maintain engagement with a film carried by the supply spool. The spool box 1 may be mounted in the camera, Fig. 2. This camera may alternatively be used without the spool box, in which case the member 13 carrying the arm 19 is inserted in the camera housing 4, Fig. 2. As the amount of film on the supply spool decreases, a part 22 on the arm 19, Fig. 6, slides off a pin 24 in the member 13 with the result that this pin moves upward due to a pivoted lever 27 engaging a pin 25. Lever 27 therefore moves upwardly to engage at 32 projections on a disc 31 carried by a spring motor driving the supply spool and so arrests the motion of the supply spool. The pin 25 may be manually depressed to release the spring motor by a slide 37, the end 36 of which is bevelled to engage the pin 25. This slide is returned to its original position shown in Fig. 6, by insertion of the member 13 or of the spool box which are provided with inclined control surfaces 15, 11 for this purpose.

Title: Improved apparatus for generating sequences of electrical pulses
IPC: H03K17/73
Filed: 1962-05-24
Abstract: 964, 376. Signalling by visible signals. SVENSKA A.B. GASACCUMULATOR. May 24, 1962 [June 13, 1961], No. 19992/62. Heading G4F. [Also in Division H3] A circuit for generating pulse sequences comprises a souce 1 of clock pulses feeding a chain of monostable circuits 4, 5, 6 &c. the output pulse sequence being obtained from corresponding terminals of alternate monostable circuits. As described, negative clock pulses are generated by an astable multivibrator 1 comprising transistors 13, 14 and are fed to the first (4) of a chain of monostable multivibrators each comprising a normallyconductive transistor 17 and a non-conductive transistor 16. Each clock pulse reverses the conductive state of transistors 16, 17 for a period determined by the circuit parameters. Each monostable multivibrator provides a positive pulse at terminal 8 during the unstable period, a positive potential at terminal 9 and a negative potential at terminal 10 during the stable period. The controlled-rectifier 18 is triggered by the onset of the first positive pulse from terminal 8 of circuit 4, energizing a lamp 11. At the end of the first unstable period, the controlled-rectifier 19 is triggered by the onset of the positive potential from terminal 9, interrupting the current in rectifier 18 and lamp 11. The second multivibrator 5 is triggered at this time and determines the duration of the interval between the first and second output pulses. At the end of the unstable period of multivibrator 5, multivibrator 6 is triggered, energizing lamp 11 for the second time for a period determined by the parameters of circuit 6. The number of monostable multivibrators required is equal to the sum of the number of pulses and of the number of intervening intervals between the pulses of each sequence. The multivibrators 4-6 may have different unstable periods so that the parameters of the pulse sequence may be altered by interchanging the multivibrators in the different stages.
