Title: Improvements in apparatus for producing liquid drops
Inventor: COYLE MICHAEL BARNARD
IPC: H01F7/08
Filed: 1954-03-25
Abstract: 770,769. Drop-delivering apparatus. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. March 24, 1955 [March 25, 1954], No. 8802/54. Class 106 (5). Apparatus for producing falling liquid drops of uniform size at a predetermined frequency comprises a pipe T for conveying the liquid from a source of supply and terminating in a downwardly directed nozzle J, and means for causing oscillatory movement of the pipe T arranged so that the downward movement is abruptly arrested, whereupon a drop of liquid is shaken from the nozzle J. The pipe T is flexible and secured to an arm A1 which is pivotally supported on a knife edge O and connected to two springs Cl, C2 so that it tends to be raised from a stop S into contact with a second stop (not shown). An electromagnet E1 energized through a rotary switch from a D.C. supply causes the arm A1 to oscillate at a frequency nearly resonant with the frequency of the impulses applied to the magnet El. Some of the drops may be deflected from the main stream by a pulse of gaseous fluid from a nozzle N, the pulse passing through a shutter M 1, M2 operated by an electromagnet E2 in synchronism with the magnet El by an electronic control circuit including a counter tube. Drops of very small size may be formed by inserting a fine wire into the nozzle J. When liquids, such as alcohol or paraffin which wet surfaces easily, are employed, a suction tube (not shown) is mounted near the nozzle J to remove surplus liquid from its exterior.

Title: Improvements in locks
IPC: E05B67/36
Filed: 1948-03-25
Abstract: 639,639. Portable locks. INGERSOLL, Ltd., YOUNG, L. W., and TAYLOR, J. W. March 25, 1948, Nos. 8835 and 31153. [Class 44] A portable lock comprises a casing apertured to receive a pin on one part and containing a key operated pin tumbler or lever type locking mechanism for locking the casing to the pin the casing abutting the other part to prevent the two parts being separated. In one form shown in sections at right angles in Figs. 3, 5 and 6, a locking disc 9 mounted on the cylinder 2 of a barrel lock has a keyhole slot 16 co-operating with an annular groove 9a in the pin 11. The locking disc is spring loaded to the locking position and is normally retained in the unlocking position by an axially sliding catch 14 spring loaded towards the locking disc. When the pin is introduced into the casing, the catch member 14 is displaced to release the locking disc which then moves to the locking position engaging the groove 9a in the narrow end of the slot 16. The disc 9 is movable to the unlocking position only by use of the proper key. The barrel lock body is provided with an axial slot lying opposite the key slot 3 in the unlocking position of the cylinder 2 which allows sufficient sideways displacement of the key to clear the tumblers for withdrawal. Alternatively the barrel lock body may be formed with a " V " shaped notch to receive the pin tumblers when the cylinder is in the unlocking position. In another form, Fig. 17, the device is unlocked by a key 4 which first engages a series of tumblers 36 to align notches 38 formed therein and then upon further rotation, by contact with a pin 45 moves the locking disc 41 to the unlocking position, an arm 40 on the disc entering the aligned notches. A pivoted catch 46 having a hook 47 engaging the arm 40 to retain the locking disc in the unlocking position is tripped by the taper head of the pin to allow the locking disc to move to the locking position. The tumblers 36, disc 41 and catch 46 are spring loaded by rubber tubes as 44 retained in notches as 42 which are distorted by compression. The device may be applied to secure hinged windows and doors, the pin being mounted on one part and an apertured bracket on the other passing over the pin and secured by the lock casing. The bracket may be dispensed with, the lock casing itself overlapping the other part and preventing relative movement. Fig. 14 shows the device applied to a sash fastener comprising a spring controlled swinging arm 32 of channel section which is held in the securing position by the lock casing 1. Removal of the casing from the pin carried on the other sash 33 allows the arm to swing to the unfastened position.
