Abstract: 207,292. Lea, N., and Radio Communication Co., Ltd. Sept. 9, 1922. Condensers. - An electrical indicating or measuring device comprises a detachable circuit element bearing a scale traversed bv a pointer controlled by a non-detachable circuit element, the scale being calibrated so that the indication of the pointer is determined by the dimensional properties of the detachable and non- detachable circuit elements in conjunction. As shown in Fig. 1, applied to an oscillatory circuit for varying wavelength or frequency, an inductance 1 of fixed value bearing a scale 2 calibrated in accordance with its dimensions, is detachably mounted in spring contacts 5, 6. A variable condenser 7 which is non-detachable operates a wire 9 carrying a pointer 8 which co-operates with the scale 2. The detachable element may be a condenser of fixed value used in conjunction with a non-detachable variable inductance, or it may be used in conjunction with a non-detachable variable condenser having a fixed inductance connected across it. When the circuit values require wider variation than is permitted by one detachable element, the latter is replaced by another of different dimensions.

Title: Key-identifying lock system
IPC: E05B35/00
Filed: 1965-06-15
Abstract: 1,066,704. Selective printing. LOCK-TRONIC CORPORATION. June 15, 1965 [July 16, 1964], No. 25159/65. Heading B6F. [Also in Divisions E2 and G1] A lock apparatus comprises a lock operable by each of a plurality of keys of different identifying shapings and means responsive to the shaping of each such key when used in the lock to produce an electric signal which is selectively representative of the identity of that key. The keys have similar broachings and a shank part of different lengths. A key in the lock cylinder 20 displaces a square-sectioned shaft 65 against spring action. The shaft has an end gear 86 in mesh with a gear train which includes a gear 97 which engages teeth 102 of a rack on a bolt 100. The shaft 65 passes through an aperture in a sleeve 55 secured to a plug 35 in the key cylinder 20 so that, by turning the key, the shaft 65 rotates and unlocks the bolt. A number of spaced contacts 75a-75e each corresponding to one key are supported by an extension of the cylinder 20 to lie aligned with a gap in a contact ring 70 secured to a sleeve 58, slidable on sleeve 55, and secured to the shaft 65. The contacts are positioned so that on turning the key one contact engages the sides of the gap in the ring 70 to complete a circuit to one of three solenoids 151, 152, 153 which are connected to three rods 141, 142, 143 one of which is thereby rotated so that a line on the base of the rod is moved to be diagonal to a second strip 130 unwound from a spool 131. The end of the bolt has a cam which operates a microswitch allowing a capacitor to discharge which operates a relay and a solenoid 220 linked to a pivoted hammer 180 which strikes the underside of the strip to record the diagonal line thereon at the same time recording the time in hours by an hour printing wheel 167 on a clock 160 and minutes by an element 171. As the solenoid de-energizes the hammer pivots and a finger 221 thereon rotates a pivoted pawl 201 to disengage from a ratchet 200 on the shaft of a motor 185 driving the drive roll 133 of the spool and engages a microswitch 210 to close the motor circuit for the strip drive roll until the pawl engages between the next pair of teeth on the ratchet and the switch 210 opens and the drive to the roll ceases. The lock can be operated from the inside by a key which moves inwardly a shaft carrying the gear 97 to break the gear train and allow the shaft to be rotated to unlock the bolt. The bolt may also be locked by a pin which engages in the arcuate end of a groove on the end of the bolt and released therefrom by a key with three lines recorded on the strip. The link may be linked with other locks so that they are interdependent. If the cover of the recorder is opened the circuit is closed over the solenoids and three lines are recorded. The clock's hour indicating wheel has a tooth which also closes a contract at a predetermined time to record three lines.

Patent GB-1003278-A (GB)
Title: A process for separating melamine from waste gas
IPC: C07D251/56
Filed: 1964-06-19
Abstract: Melamine is removed from a mixture of molten melamine and NH3 and CO2 gases by spraying same with water in a separator, the amount of water being so controlled that the average diameter of the water drops is less than 200m  and the temperature in the separator is between 90 DEG  and 200 DEG  C.  The cooling effect, due to the latent heat of evaporation of the water droplets into water vapour, reduces the temperature of the NH3 and CO2 gases, which in turn cool and solidify the melamine without significant hydrolysis taking place.  This cooling effect may be supplemented by the additional use of a cooling gas such as ammonia. Specification 1,003,277 is referred to.
