Title: Multi-channel combustible gas detector
IPC: G01N33/00
Filed: 1974-03-26
Abstract: 1419361 Measuring gas concentration electrically GENERAL MONITORS Inc 26 March 1974 13358/74 Heading G1N A system for measuring the concentration of a combustible gas in an atmosphere has two parallel sensor circuits feeding into a comparator which provides an indication of the higher concentration, the system including means for indicating malfunction. As shown, Fig.2, two catalytic type resistance sensors 16, 18 are connected in individual bridge networks fed from separate current sources 12, 14. The outputs from the bridges are compared at 52 and the larger signal causes operation of switch 58 or 60 to by-pass the smaller signal and selectively energize the appropriate indicator lamp 80 or 82. The larger signal is further amplified at 84 and fed to a threshold detector 92 associated with alarm devices 108, 118 for a low or high level of gas concentration. The currents fed to the sensor networks are noted at 130, 132 which send corresponding signals to AND gate 134. If one or both currents are missing, an alarm relay 138 is energized. In an alternative arrangement, Fig. 4 (not shown), the output signals from the sensor bridges are fed to a common point through diodes, whereby the largest signal back biases the diodes in the other channels.

Patent GB-134968-A (GB)
IPC: B66C3/06
Abstract: 134,968. Hollich, W. J. Nov. 23, 1918. Grab-buckets; lifting-dogs and the like.-Relates to suspension or coupling devices for single or double chain grabs, lifting-dogs, &c. As applied to a single-chain grab, the chain t, Fig. 2, passes round pulleys q, v to the cross-head j, the bottom pair of pulleys q being mounted on a cross-head p having slides engaging guides s and a centrally-arranged rotatable cam-plug o adapted to enter a tubular block k bolted to the frame g to which the grab-buckets e are pivoted. The block k carries oppositely-arranged pins n adapted to engage the cam-plug, which, as shown developed in Fig. 1, has three sets of cam-faces a, b, c, the cam-faces a, b being separated by slots d. In operation, with the buckets open and the upper end of the cam-plug abutting against the top pulley, the grab is lowered on to the material, and the chain further paid out so that the cam-plug enters the block, the pins being guided by the cam-faces a into the slots and striking the cam-faces c<1> so as partly to rotate the cam-plug. The chain is then hauled in until the pins engage in the angles between the cam-faces b and support the buckets, so that a further paying-out of the chain allows the buckets to close, and the grab can then be hoisted and swung to the discharging point. By lowering the grab to the ground and further paying out the chain, the pins are guided by the cam-faces c<2> into the angles between the cam-faces c, and hauling-in the chain then allows the pins to pass through the slots, thus freeing the buckets and allowing them to discharge. The positions of the cam-plug and block may be reversed. A second cam-plug may be provided and is suspended from the jib of the crane, and co-operates with a pin-carrying member mounted on the cross-head j, the arrangement forming an automatic suspension device for the grab. The pulleys may be dispensed with. For use with double-chain grabs, the cam mechanism serves for opening and closing the buckets, the second chain supporting the grab.

Title: Multi-stage liquid-ring gas-pump
IPC: F04C19/00
Filed: 1957-04-29
Abstract: 858,422. Liquid-ring pumps. SIEMEN, O., and HINSCH, J. April 29, 1957 [May 2, 1956], No. 13502/57. Class 110 (1). In a multi-stage liquid-ring gas pump, liquid for sealing the impeller clearances is drawn from the output chamber of the respective stage, liquid for maintaining the liquid rings (by replacement of liquid entrained by the pumped gas) is drawn from liquid present within the pump, and liquid for cooling the pump is drawn from an outside source. In the two-stage liquid-ring pump shown, gas enters the first stage by way of an inlet 1, suction chamber 2 and suction port 23, and is discharged through a port 26 to an interstage chamber 20 containing a weir 19. The gas then enters the second stage through a port 27 and is discharged by way of a discharge port 28, discharge chamber 12 and outlet 13. Liquid separated from the gas in the chambers 20, 12 returns to the respective stages through ports 30, 32 and passages 31, 33 in the impellers 4, 9 to seal the clearances between the impellers and the transverse walls. The liquid ring of the first stage is replenished from the chamber 20 through a port 34. Alternatively, the replenishment may be effected through the opposite transverse wall 3 by way of an additional chamber connected to the chamber 20. If necessary, the liquid ring of the second stage may be replenished from the chamber 12. Sealing liquid for stuffing-boxes 37, 38 is drawn from the liquid-ring of, say, the first, stage through a port 39. Interstage leakage along the pump shaft is prevented by a seal-ring 17 which is pressed against one wall of a recess 18 by the pressure difference between the two stages. Liquid lost by entrainment with the gas leaving the pump is replenished by feeding liquid to the pump from an external source through an inlet 14 or 15, or both, the quantity of liquid supplied being no more than sufficient to cool the pump. The liquid entering through inlet 15 passes to the first stage with the gas being pumped, while that entering through inlet 14 passes directly to the first stage through a port 29.

Filed: 1924-06-04
Abstract: 232,433. Volkers, E. June 4, 1924. Reciprocating and oscillating machines. - A toothed rack or ratchet wheel 6 is intermittently advanced by a self-interrupting magnet 1 which, when energized through the closing of contact 8, 9. is attracted towards its armature 4. The armature is prevented from moving by its contact 8 engaging the fixed contact 9, but the magnet 1, which is connected to the armature by a spring 5, rotates about an axis 3, engages the armature, and carries it with it into the dotted-line position, thereby separating the contacts 8, 9 and causing a pawl 7 to slide over the wheel 6. The magnet 1 then falls by its own weight or by a spring, causing the pawl 7 to rotate the wheel 6 and the contacts 8 to re-engage the contact 9. Several ratchet wheels 6 may be driven simultaneously by arranging their magnets in one circuit, but in this case only one pair of contacts 8, 9 is necessary.

Abstract: 1,139,823. Walking beam conveyers. DAVY & UNITED ENG. CO. Ltd. 23 March, 1967 [29 March, 1966], No. 13750/66. Heading B8A. In a walking beam conveyer used as a cooling bed, each walking beam 1 is moved upwardly as wheels 6 run up ramps 11 when links 21 are moved to the right in Fig. 3. With the objects undergoing cooling clear of fixed beams 2, the links 21 and wheels 6 are made stationary and the beam 1, supported on rollers 3, is moved to the right by piston-cylinder means (not shown). To return the beam 1 to its original position the links 21 are moved to the left before moving the beam to the left. The ramps 11 are longitudinally adjustable. In a modification, Figs. 4, 5 (not shown), the ramps are connected by links (30) and are slidable longitudinally to allow for expansion due to heating. Instead of the wheels 6, skids can be used.

Title: Improvements relating to digital adding circuits
Inventor: ROBINSON NIGEL DAVID
IPC: G06F7/38
Filed: 1957-04-30
Abstract: 893,353. Parallel adders. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 21, 1958 [April 30, 1957], No. 13797/57. Class 106 (1). A parallel binary adder, one stage of which is shown, has two lines between which a carry signal is steered (after entry of augend and addend) to enter carries on magnetic cores 7 of appropriate states, for subsequent entry into core pairs 5, 6 recording the total. Cores 5 and 6 are arranged with transistors T1, T2 so that one core is always set (when core 6 is set the stage registers "1"), since resetting of either core produces a pulse which when lengthened by the transistor hole-storage effect sets the other. The action is: (a) a " clear " pulse resets 6 (if previously set) of each stage; this sets cores 5 and 2 and resets 1. (b) The augend is entered as a pulse (for 1) or no pulse (0) to each stage; each pulse, being applied through H to both cores 5, 6 switches the trigger 5, 6 and hence the states of cores 1, 2 are interchanged. (c) The addend is entered in the same way if this causes 6 to be reset cores 3 and 4 will be set and reset respectively with the aid of a simultaneous pulse on the control line, otherwise core 4 will be set. (d) A carry pulse is applied to the C input of the lowest stage simultaneously with an interrogate pulse which resets any set cores in the group 1-4 to block (by biasing the corresponding diode) the path through it from right to left. Thus if a stage receiving a carry at C n-1  is registering a " 1 " it steers the carry signal to the no-carry output C n , while if it is registering a " 0 " it steers it to C n . Similarly a no-carry input (C n-1 ) is steered to C n  unless the stage has just been switched from 1 to 0. The carries are registered in cores 7. (e) A " transfer carries " pulse adds in any carries, to produce the correct sum.
