Title: Methods for recovering metal ions from aqueous solutions thereof
IPC: B01J41/16
Filed: 1971-04-20
Abstract: 1351272 Recovering metals from solution W C HERAEUS GmbH 20 April 1971 [2 May 1970] 10268/71 Heading C1A Metal ions and ions containing metals from Groups 1b, Va, VIa, or VIII of the Periodic Table are recovered from their aqueous solution by passing the solution through a carrier material comprising cellulose which has been impregnated with polyethylene imine and is substantially free from unbound polyethylene imine which is removable by washing with water, and subsequently eluting said carrier material with a reagent which displaces the absorbed metal ions from the impregnated carrier material. The solution may also contain ions of metals other than those from the group specified, and the cellulose may be natural cellulose free from lignin, or cellulose regenerated from viscose or cuprammonium rayon. Examples illustrate the recovery from aqueous solution of copper, palladium, vanadium (as vanadate), molybdenum (as molybdate), and of tungsten (as tungstate) and molybdenum (as molybdate) from a solution containing both.
Patent GB-538323-A (GB)
Title: Improvements in or relating to control systems for electric elevators or the like
IPC: B66B1/36
Filed: 1940-06-14
Abstract: 538,323. Control of motors. IGRANIC ELECTRIC CO., Ltd. June 14, 1940, No. 10370. Convention date, July 10, 1939. [Class 38 (iii)] A lift motor M is de-energized and braked when the car is a pre-determined distance from a floor, the distance being such that with a normal load the car will stop level with the floor. Should the car, due to abnormal load, stop short or overshoot the floor by another predetermined distance then the motor is restarted in the appropriate direction and again deenergized at a lesser distance from the floor. The levelling operation is controlled by an open core transformer 22 on the car co-operating with a fixed armature 25 in -the shaft through the medium of gas discharge valves 20 21. With the car switch CS in position D, contactor 2 and relays 16, 17 are lifted causing lift to travel downwards. It switch CS is returned to "off" as the car approaches a floor, relay 16 drops and completes the anode-cathode circuit of the valves, and armature 25 is so related to the transformer 22 that valve 21 conducts causing relay 19 to lift, thus maintaining contactor 2 and relay 17 up. When transformer 22 moves to a more central position relatively to the armature 25, valve 21 ceases to conduct and relay 18, and contactor 2 drop. After an interval sufficient for the motor M to come to rest, relay 17 drops and by shorting resistance R2 alters the grid bias on the valves, so that if the car and therewith the transformer has stopped short or overshot the floor, valve 21 or 20 conducts with consequent closure of contactar 2 or 1 and further levelling of the car. Specification 414,323. [Group XXX], is referred to.

Abstract: 786,521. Latches. WILMOT-BREEDEN, Ltd. March 29, 1956 [April 12, 1955], No. 10429/55. Class 44 A vehicle door fastening comprises in combination, a body part 4, 5 for attachment to the door having a slot 6 for the reception of a striker 7 on a relatively fixed part of the vehicle body, a rotary toothed catch 9 on the body part for engagement with the striker when disposed within the slot, a pawl 11 pivoted on the body part and having a pair of teeth 11a and 11b for alternative direct engagement with the catch, one of the teeth 11a being adapted to engage the catch in a fully latched position of the door and the other being adapted to engage the catch in a safety position, and means for rocking the pawl in a catch releasing direction from the inside and from the outside of the door. As shown, the pawl 11 is biased to catchengaging position by a spring 12 and is releasable from outside the door by means of a pin 16 on a spring loaded lever 13 which latter is actuated by a push button 14. One arm of a lever 17 mounted on the body part at the inside of the door is located beneath a shoulder 11c on the pawl, so that movement of the lever in one direction releases the pawl from the catch 9. Movement of the lever in the opposite direction causes a part 17a to block movement of the lever 13 from the outside of the door.

Patent GB-105676-A (GB)
IPC: B23K9/10
Abstract: 105,676. British Thomson - Houston Co., (General Electric Co.). June 27, 1916. Heating by electricity.-An arc welding system is provided with an overload protective device adapted to operate at substantially a constant per cent overload. A compound-wound generator 1 is connected to the work piece 3 and to the electrode 2 through a switch 12, a fixed resistance 6 and a rheostat 5 which is used to regulate the current. An automatic contact-breaker 4 may be used to operate with such overloads as do not affect the protective device referred to. The switch 12 is kept closed by a solenoid 14 connected across the generator through a switch 13 which is normally closed but is opened by a solenoid connected across the rheostat 5 when the voltage-drop rises above a certain value. The solenoid 15 is connected to the electrode side of the rheostat through resistance 22 and also, when the arm 7 engages one of the low resistance points, directly by a lead 20 and conducting sector 8. These are usually employed with a carbon electrode while the higher ones are used with a metal electrode. The increased voltage-drop due to the metal electrode is compensated for by the resistance 22 introduced into the circuit of the solenoid 15 when the arm 7 passes on to the non-conducting sector 9. If it is desired to use the high resistance points with a carbon electrode, the resistance 22 is cut out by a hand-operated switch 23.

Title: Improvements relating to abrasive preparations and their method of manufacture
IPC: C11D7/44
Filed: 1949-04-22
Abstract: An abrasive vegetable product, for use in cleaning metal parts &c. comprises the relatively coarse granular particles obtained by suitably grinding the outer husks of stones of fruit of the prunus type or the decorticated wastes of nuts, such as almonds or walnuts. Plum and damson stones are specified.  In the case of whole fruit stones, the stones are first dried to a low moisture content and then ground in grinders of the hammer mill or beater type, or pin mill grinders of coarse setting of the pins or stone grinders set for coarse grinding.  The grinding is stopped when most of the material, consisting mainly of the kernels, is reduced to powder, but a substantial proportion, about 30 per cent, of coarse granular particles derived from the husks remains.  The product is then sieved, the fine powder being used as animal feeding stuffs.  The retained coarser granules comprises the abrasive product.  The overs from the sieving may be graded by further sieving operations to give abrasives of different grades of fineness.
