Title: Drag line materials handling truck
IPC: B61B13/12
Filed: 1951-01-15
Abstract: 685,892. Haulage of trucks by travelling rope, &c. JOHNSON & JOHNSON. Jan. 15, 1951. [Jan. 14, 1950] No. 1123/51. Class 104 (ii). A materials handling truck to be hauled by a travelling drag line, has its connecting device normally biased into engagement with the drag line but disengaged therefrom when a member mounted on the truck is moved on encountering an obstacle such as another stationary truck. The connecting device normally remains in the slot of the drag line runway in readiness for reconnection with the drag line when the obstacle is removed but can be manually raised out of the slot to allow complete freedom of movement of the truck. A truck 10 is drawn along by a rod 18 engaging a frame 24 fixed on the pivots of the links of a driving chain 11 and supported by rollers running in channels 20. A bumper 38, supported on L-shaped arms 39, is pivoted upwards on meeting an obstruction to partially rotate a pair of arms 43 to lift a sleeve 35 which through a spring 36 and collar 37 raises rod 18 out of engagement with the frame 24. To prevent recoil, brakes 52 are applied to the rear wheels as the bumper 38 moves upwards and so allows a counter-weight 45 pivotally held on the arms 43 to press on an arm of a bell crank 60 connected through a rod 58 to the brakes 52. The bumper 38 is held in the upper position by a notch 68 in a lever 65 engaging a lip 70 on the bumper 38. The rod 18 normally remains in the slot 22 above the chain 11 but it may be manually lifted clear by means of a handle 75 and locked in the upper position by a catch 72 engaging a collar on the rod 18. The spring 36 absorbs the shock when the rod 18 is dropped from its upper position. Manual rotation of the catch 72 disengages the notch 68 from the lip 70 by bearing against a boss 69 on the lever 65. The truck may be stopped by a shoe 78 fixed above the guide slot 22 so that a collar 80 rides up an inclined surface 79 thereof to lift the rod 18 out of driven engagement.

Title: Improvements in Apparatus for Registering the Number and Duration of Rotations of Intermittently Revolving Shafts.
Inventor: BRUHN FRIEDRICH WILHELM GUSTAV
IPC: G01C22/00
Filed: 1916-01-28
Abstract: 103,352. Bruhn, F. W. G. Jan. 28, 1916. Registering time of waiting, stoppage, or use of vehicles; with distance totalizers.-Apparatus for indicating the number and duration of the rotations of an intermittently rotating shaft, such as the main shaft of a taximeter, comprises two counters one driven from the shaft and the other by a clock which is stopped when the first shaft is at rest, the indications afforded being the distance run or the revolutions made and the time occupied thereby The distance or revolution counter 44 is driven from the shaft 38 through worm gearing 39 - - 42. Also driven from the shaft 38 through toothed gearing 43, 46 is a shaft 47, on which is secured one end of a spiral spring mounted in a barrel 48, the toothed portion 49 of which is similar to the wheel 46. The free end of the spring is in frictional engagement with the interior of the barrel controlled by an escapement 52. Mounted to engage with the wheels 46, 49 are two pinions 55, 54, the first of which is formed as a nut carried on the screwed upper part of a shaft 56, the remaining pinion being loose on the shaft and rotated through a spring 58 and a disk 59 secured thereto. A spring lever 61 adapted to stop the clock is engaged by a groove 60 formed in the upper part of the pinion 55. In operation, when the speed of the wheel 49 exceeds that of the wheel 46 due to the stoppage of the shaft 38, the pinion 55 moves up the shaft 56 and brings the spring lever into position to stop the clock, the movements being reversed when the shaft 38 commences to rotate again. The counter 66 is driven by worm gearing from the clock, which may be a continuously-running one thrown into and out of gear by the movement of the pinion 55. When applied to a taximeter, the time-drive is thrown into and out of gear by the flag, and the duration of the waiting times may be obtained by the difference between the time shown on the counter 66 and a counter showing the sum of the engaged periods. Alternatively, the apparatus may be modified to show directly the total of the waiting times.

Title: Electric control apparatus for an electric storage heater
IPC: F24D11/00
Filed: 1975-01-14
Abstract: 1468112 Temperature control DANFOSS A/S 14 Jan 1975 [15 Jan 1974] 1520/75 Heading G3R [Also in Division H2] In a thermostatically-controlled electric storage heater, a blower 10 or the equivalent releases stored heat whenever the ambient temperature is sensed as too-low by the thermostat 15, the length of time that this condition prevails being recorded by an integrator 22 so that, during a subsequent re-charging period of the heater, the heat input may be related to the heat loss during the discharge period. However, should the ambient temperature rise too high, the integrator receives a negative input so that what is ultimately recorded is the length of time the ambient temperature was toolow minus the time it was too high. This integrated signal may be further modified in response to a detection of a too-low heat flow-rate during 'on' periods of the blower. During the discharge phase, a solid-state switch 24 is open and a like switch 21 closed, the latter passing on to the integrator positive and negative signals fed to its inputs 19 and 21 from the 'toolow and 'too-high' temperature positions 17 and 18 of the thermostat switch leaf 16. A further input to the integrator 22 is from a sensor 23 which  detects the uncontrolled output from the heater 8 i.e. the heat emitted even when the fan is not running, which heat must be allowed for in the subsequent charging phase. Should the storage heater become too cool, because of initial undercharging, a switch 12 closes to energize a heater resistor 25 in the thermostat unit 13. This causes the blower 10 to behave effectively as it would if stored heat were available, so that the integrator input 19 is corrected for the undercharging. During the charge phase, a clock 3 completes a supply circuit between terminals 1 and 2 to the storage heater element 7 and also, via line 27, opens switch 20 and closes switch 24. The latter, via the broken-line connection, closes a switch 5 for a period of time determined by the integrator 22. During this phase, the blower 10 can still be switched on if the room becomes too cool, but the integrator, because of the opening of switch 20, is ineffective. The solid-state switches 20, 24 may be replaced by mechanical switches and the electronic integrator 22 by a mechanical one.

Filed: 1918-01-26
Abstract: 130,358. L'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. Aug. 9, 1917, [Con- 1917, [Convention date]. Gases, separating mixtures of.-Hydrogen is extracted from gas mixtures that contain it, for example from water gas, coal-gas, or coke-oven gas, by treating the gas mixture with ether at a pressure of 50 to 300 atmospheres and at a temperature of -40 to -60 C., to dissolve out the other constituents. Other solvents, for example methyl acetate, which have the same power of dissolving carbon monoxide, the same ratio of solubility CO/H, and the same temperature coefficient of this solubility ratio, may be employed. A suitable apparatus comprises a compressor C for the gas mixture, a refrigerating-tank B, a thermally-insulated absorption column A filled with balls or plates, a circulating-pump E, and a tank D in which the solvent gives up its dissolved gases. The cooled and compressed gas, rising in the column A, meets the descending solvent, and practically pure hydrogen is liberated through the valve V. The saturated solvent escapes through the valve V to the refrigerating- tank B and, before passing to the tank D, acts upon the piston E to assist in returning the unsaturated solvent, sucked up from the tank D, to the top of the column A. To avoid loss of solvent, the dissolved gases may be liberated in two or more stages, first at a pressure greater than atmospheric, for example at 10 to 50 atmospheres, and finally at atmospheric or less than atmospheric pressure.

Abstract: 344,149. Protective cut-out systems. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and WILSON, W., of General Electric Co., Witton, Birmingham. Jan. 21, 1930, No. 2094. [Class 38 (v).] A balanced protective system for three or more parallel feeders has coils of the relays associated with a common circulating-current system so arranged that disturbance of balance causes operation of two relays which together control a circuit and effect isolation of the faulty feeder. As shown in Fig. 1 three parallel feeders 4, 5, 6 extend from a supply conductor 17, transformers 1, 2, 3 in the feeders forming a common circulating-current system in series with the coils 14, 15 of doublepivot differential relays corresponding to each feeder. On disturbance of the normal current balance between the feeders as by a fault in the feeder 4 an out-of-balance current flows in one coil i.e. 14 of the relay corresponding to this feeder, passes through a neutral conductor 23 and returns through a coil of another relay, i.e. coil 15 of the relay corresponding to feeder 6. As a result these relays are operated in opposite directions and a tripping circuit is completed through their seriesconnected contacts. This circuit as shown in Fig. 2 comprises a conductor 43, relay contacts 31, 32 bridged by conductor 25, lead 53, relay contacts 41, 42 bridged by conductor 30 and the common return lead 46. Thus for any fault in any feeder, either an earth fault or an interruption in the feeder circuit two relays are operated to complete together the tripping circuit of the corresponding circuit-breaker. The double pivoting of the relay beams ensures a predetermined amount of unbalance before the relays operate. The opening of a circuitbreaker changes over a corresponding switch 18 to enable the protective gear of the remaining feeders to operate.
