Title: Improvements in or relating to devices for facilitating the suspension or transport of articles containing spillable media
IPC: A47G23/06
Filed: 1948-12-03
Abstract: 660,822. Self-levelling arrangements. BALDOCK. G. F. Dec. 5, 1949 [Dec. 3, 1948], No. 31392/48. Class 113 (i). A device for facilitating the transport of spillable media comprises a rigid frame 3 having means for carrying a container 13 for spillable media and also having a handle 2, hook, loop, or the like universally pivotally connected thereto at a point 36 above the centre of gravity thereof and enabling the device to be carried in the hand or suspended from a hook, projection or the like on a wall or on the structure of a vehicle, tray, trolley, or the like. Two concentric rings carry the container 13, the inner ring 38 of the pair being journalled to the outer ring 42 at 39 at diametrically opposed locations, the outer ring being journalled to the structure 3 at 44 at diametrically opposed locations in a, vertical plane perpendicular to the vertical plane containing the journals 39 of the inner ring, hence the container 13 is floatingly supported on the ring 38 and remains so when the device is stood upon its feet 35. A locking means may be provided for holding the container carrier in its operative position or securing it in a retracted position where it is substantially parallel with the structure.

Title: Automatic block-protection for railways by means of axle counters
IPC: B61L1/16
Filed: 1933-11-11
Abstract: 424,909. Railway signalling systems. VEREINIGTE EISENBAHN - SIGNALWERKE GES., Siemensstadt, Berlin. Nov. 11, 1933, No. 31504. Convention date, Dec. 3, 1932. [Class 105] In a railway signalling system in which the signal is only cleared when an axle-counting apparatus has counted out the same number of axles as were counted in, the entrance of a train into the section puts the signal independently to danger. The entry of a train de-energizes a stick relay 10 by opening a treadle contact 50 or by shunting out the relay in a short entrance track section and the relay 10 at its back contact 13 then lights the danger lamp 53 of the signal. When a wheel-actuated contact device 51 has actuated the counting-in magnet 25 of the axle counting apparatus and so opened a contact 250 a relay 40 is de-energized and a back contact 42 thereof is closed to pick up the relay 10 which then sticks over its own front contact 12. The danger lamp 53, however, continues to be lit in spite of the change over of contact 13 of relay 10 since contact 41 of relay 40 now closes its back contact. The clear lamp 52 is not lit until the relay 40 is again energized to close its front contact 41. This necessitates that the next signal ahead 63 shows danger, that a "light in " relay 80 has closed a contact 81, and that the ahead wheelactuated contact device 61 has been actuated the same number of times so that the counting- out magnet 26 has set the contact 250 to its normal closed condition. The wheel-actuated contact device 51 may be a mechanical, inductive, or optical device. The axle-counting apparatus may normally be disconnected and only be connected in while the train is passing, for instance by a dropped contact of the relay 10.

The liquid is dialized to remove inorganic salts, and is then boiled in open vessels to remove volatile impurities and to coagulate albuminoids, the water content being maintained at about 80 per cent during boiling. After removal of the albuminoids by filtration the liquid is evaporated under reduced pressure until the water content is less than 25 per cent.

Title: Improvements in or relating to resistance bridge circuits

Abstract: 1,263,673. Resistance measuring bridges.  ROSEMOUNT ENG., CO. June 30, 1970 [July 15, 1969], No.31580/70. Heading G1U. A measuring circuit comprises a resistance bridge 22, 24, 26, 28, one resistance 22 of which is dependent on a variable condition to be measured, a further resistance 48 connected between one corner of the bridge and a reference potential 60 (earth), a power supply 16 connected between another corner of the bridge and earth, output terminals 54, 56 connected to a third corner and earth respectively, and an operational amplifier 36 having one input 40 connected to the first bridge corner and a second input 42 receiving a proportion of the circuit output voltage, and whose output is connected across a bridge diagonal. The arrangement linearizes the relation between the output voltage and the condition to be measured, and reduces lead impedance errors. The voltage supplied to the amplifier input 42 may be derived from a high-resistance potential divider 50, 52 or a further amplifier. Zero is adjusted by altering resistance 26 and sensitivity by altering resistances 24, 28, by altering the voltage of supply 16 or by inserting a resistor in series with the supply 16. A common power supply 10 may energize a plurality of similar measuring networks, two being shown, whose outputs are scanned in succession. The resistor 22 may be a platinum thermometer, a Piezoresistor or a photo-resistor.

The reducing reaction is carried out in the presence of finely divided cobalt particles until a cobalt to nickel ratio greater than 100 : 1 is obtained.  The reaction may be conducted at a temperature of above 120 DEG C. under a partial pressure of hydrogen greater than 14 atmospheres using a solution having a pH in the range 3.5-7.0.  The coated cobalt particles may be treated to strip the coating and may then be re-used in a further nickel precipitation treatment.
