Title: Improvements in or in connection with ladies' hand bags, wallets and the like
IPC: A45C3/06
Filed: 1920-08-06
Abstract: 168,235. Sutton, J. J. Aug. 6, 1920. Bags. - Relates to means for supporting a purse or the like inside a hand-bag &c., and for indicating, by preventing the closure of the bag, when the purse is absent. The purse has a strap fixed to the back adapted to take over a hooked tongue b outstanding from a metal plate c attached to the interior of the hand-bag &c. A spring- controlled loop g pivotally mounted on the plate has to be forced downwardly to place the purse in position within the bag, and then exerts a pressure against the lower edge of the purse tending to keep the upper edge pressed against the tongue. When the purse is removed, the loop g flies upwards and by preventing the closing of the hand-bag &c. indicates that the purse is absent. The device may be applied to the pockets of garments by attaching the supporting-plate to the inside of the pocket.
Patent GB-232117-A (GB)
Title: Improvements relating to electro-magnetic overload time-element tripping mechanisms for alternating current circuitbreakers
IPC: H01H71/44
Filed: 1924-10-01
Abstract: 232,117. Fabrik Elektrischer Apparate Sprecher & Schuh Akt.-Ges. in Aarau. July 15, 1924, [Convention date]. Automatic circuit-breakers for alternating current, of the kind in which the tripping is produced by the attraction on overload of an armature acting through a spring on an adjustable time-element mechanism, have a tripping mechanism provided with a subsidiary armature 2 which, when the predetermined overload is reached, is attracted against the action of an adjustable setting spring 13 and opens a short-circuited winding 4 on the main armature 11 which is thereupon attracted and, in connection with the time-element mechanism 5, serves to trip the circuit-breaker. By these means a more critical setting of the time-element feature of the circuitbreaker is obtained, independent of the setting of the overload spring 13. Normally, the closed winding on the main armature diverts the flux therefrom, and the attractive force of the electromagnet is at a minimum. Stray flux which tends to produce an attractive force on the armatures is kept down by a conducting sheath 18 on one of the limbs 17 of the U-shaped electromagnet. With excess current, the subsidiary armature 2 is attracted opening the short-circuit on the main armature 11 which is attracted, in turn, carrying with it an extension 10. The extension is connected through a spring 12 to a lever 9 pivoted at 8 on the same pivot as the main armature, the lever being connected to the time-element mechanism by links 7, 6. With overloads up to a certain amount, the main armature and the lever 9 move as one, united by the spring 12. With heavier overloads, however, the spring 12 is extended, as shown, and the puLl on the timeelement mechanism is confined to that transmitted through the spring. When the time-lag has expired, the lever 9 engages the tripping mechanism 15. If it is desired that, with the heavier overloads, the time-element should be eliminated a sliding plate 16 adjustable on the extension 10 is drawn out so that, when the main armature is attracted, the tripping mechanism is actuated by the plate at once.

IPC: H01H21/22
Filed: 1962-06-19
Abstract: 968,934. Keyboard switches. GENERAL ELECTRIC CO. Ltd. May 22, 1963 [June 19, 1962], No. 23554/62. Heading H2B. Twenty push-buttons are arranged in two rows of ten aligned respectively with buttons 2 and 7 shown. Each button is pivoted as shown on a part 42 of a spring such as 18, which is H-shaped and has two legs inserted through slots 41 in a support plate 20 while the other two legs urge the button upwards and carry contacts for respective engagement with conductive strips 47 and 48 common to all buttons in a row. Each button also operates a respective springset 11, only that associated with button 7 being shown. Latching means 13 comprises a bar 49, having an upstanding rib 53 for each pair of buttons, pivoted on a rod 56 passing through all the ribs. Each rib carries a short pin 59 normally lying in the path of tongues 65, 66 extending from the buttons. The tongues 65, 66 are mitred in plan view (Fig. 1, not shown) so as to be able to pass each other without interference. Each tongue has a lateral slot near its base and is chamfered as shown such that depression of a button pushes the pin 59 aside. This rotates the latching means 13 about rod 56 against the action of a restoring blade spring 62 which causes the pin 59 to return above the tongue, latching the actuated button in depressed condition (as shown in the case of button 7). If a button in the same row as 7 is depressed its tongue will rotate the means 13 anticlockwise and the pin 59 will move off the tongue 66 allowing button 7 to restore under action of its contact springs. If a button in the other row, for example button 2, is depressed it causes the means 13 to turn clockwise and the pin 59 coincides with the slot to the rear of tongue 66, again allowing button 7 to restore. Thus depression of any button in either row will allow any previously actuated button to restore while the depressed button is latched. If a button is held depressed while any one or more other buttons are also depressed all the depressed buttons will be latched.

[Also in Division C5] In a partial combustion process for making a gas containing H 2  and CO from hydrocarbons e.g. natural gas and LPG, the process is performed in a channel 12 which is enclosed by walls 10, 11 having catalytically active surfaces and which is narrow enough to ensure a temperature gradient normal to the axis of the channel of nil. The channel, which may be straight or bent, e.g. zig-zag or coiled, is not more than 1.6 cms wide, e.g. 0.1 to 0.5 cm, and the residence time in the channel is in the range 0.01 to 0.5 second, preferably 0.02 to 0.1 second. The walls may be lined with or made of the catalyst, examples being pure Ni and Ni alloy, and the walls should be subjected to an oxidative treatment e.g. with air at 1000‹C followed by reduction and further oxidation, to reduce CH 4 , H 2 O and CO 2  contents in the gas produced. Preferred temperatures for the process are in the range 900‹ to 1000‹C. The channel 12 may be formed in a conical or cylindrical vessel 10, which may be externally heated, e.g. electrically at 16, or cooled, and two or more channels, e.g. in parallel array, may be used. The process inhibits the formation of naphthalene-type compounds. The O 2 -containing gas supplied to the reaction may be air or O 2 -enriched air, and may contain CO 2  and/or water.

Abstract: 1,267,633. Radiation analysers; measuring voltage. BECKMAN INSTRUMENTS Inc. May 18, 1970 [June 2, 1969], No.23918/70. Headings G1A and G1U. In apparatus for recording the ratio of a sample radiation beam intensity and a reference beam intensity, the circuit after synchronous detector 26 is provided for offset and scaling purposes during the recording. Monochromator 2 is synchronized with the pen or paper drive of chart recorder 66 and delivers a narrow wavelength beam to a beam directing system of rotating sector mirrors 6, 8 and fixed mirrors 16, 18, to form alternately effective reference and sample paths 14, 12, the latter providing an intensity reaching the detector 22 dependent on the transmissivity of the sample. After amplifier 24, the detector 26 synchronous with motor 10 switches the sample signals on to line 28 and reference signals into line 30. If it is known that the ratio between the voltages on lines 28, 30 will only vary between, for example, 70% and 90% transmission, it will be required to record only the values of the ratio in this range. This necessitates rendering 70% as the zero input to the recorder and scaling up any variations above this value so that 90% represents the maximum. To do this the circuit comprises two differential amplifiers 34, 32, one for the sample and one for the reference signals and each provided with feedback to its inverting input. Offset is provided by use of resistor 44, the tap 46 of which is pre-set to deliver 70% of the reference signal at 42 to the inverting input of amplifier 38. Scaling of the signal passing through the sample channel is effected by pre-setting the gain of amplifier 34 by adjustment of variable resistor 58, this gain being dependent on the ratio of the sum of the resistances of 58 and 56 to the resistance of 56. A mathematical discussion giving the derivation of the relationship between the ratio of the amplifier outputs, the ratio of the inputs, the offset and the scaling factor, is provided.
