Title: Improvements in and relating to electric devices for operating hoists, cranes and the like
IPC: B66D1/48
Filed: 1937-12-21
Abstract: 508,067. Winches. TUSTIN, A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 21, 1937, No. 35409. [Class 78 (v)] An electric motor equipment for operating hoists, cranes, &c. comprises a main drumactuating motor and an auxiliary motor whereby sufficient power is applied to the drum to allow of manual control of the hook, &c., the drum and auxiliary motor then running independently of the main motor so that movement of the drum is not imparted to the main motor. The auxiliary motor may be coupled directly to the drum, or through gearing, the moment of inertia of the auxiliary motor, either direct or through gearing, being always such as to impose no undue resistance to manual movement of the hook. Fig. 1 shows a winding drum 1 fixed on a shaft 9 to which is directly coupled an auxiliary motor 3. A main motor 2 drives through a pinion 7 a gear wheel 8 loose on the shaft 9 but capable of imparting rotation thereto in the winding-on direction by pawls 13 engaging a ratchet wheel 12 fixed on the shaft 9.. Magnetic means may be provided for disengaging the pawls from the wheel 12 to free the motor 2 completely in both directions. This consists of a coil 16 surrounding the pawl cage 81, Fig. 4, and acting on a magnetic pawl 85 normally biassed by a spring 86 into engagement with the ratchet wheel 12 through an opening 89 in the inner run of the cage. The pawl 85 is pivoted to a block 84 fixed to this inner rim, so that when said pawl is released by de-energization of the coil 16 it drops into engagement with the wheel 12 and is forced thereby to turn the rim 81 through an angle which permits the remaining spring-pressed pawls 13 to pass through openings 83 in the run and to engage the teeth of the wheel 12 without danger of catching on to the tips thereof. When the magnetic pawl release is not employed, the main motor is driven in the non-lifting direction so rapidly that no manual action combined with separating movements of the boom end and load will overtake it. In a modified arrangement the main motor is geared to a toothed wheel loose on a shaft co-axial with, and connected by pawl and ratchet wheel to, the drum shaft, a friction clutch being provided between the loose wheel and its shaft. A ring coil arranged around part of this clutch releases same when electrified, but when de-energized allows springs to force the frictional faces of the clutch together.' In a third form the two motors and the drumare co-axially arranged and are connected together through an epicyclic gear disposed within the drum. The auxiliarymotor drives through a ratchet-wheel engaged by pawls controlled by a circumferential electric coil. The motors may be operated in a constant current circuit which may be supplied by a metadyne. Electro-magnetic brakes 18 may be provided on the main motor shaft 4. 19 is an exciter which energizes the main motor winding in a direction opposed to its motion when it rotates above a limiting speed, thus keeping the speed of the drum down to safe values in both directions.

Title: Automatics electrometric analysis
IPC: G01N27/00
Filed: 1973-07-25
Abstract: 1440198 Electro-chemical analysis PHOTOVOLT CORP 25 July 1973 [26 July 1972] 35462/73 Heading G1N In the electrometric analysis of a liquid specimen a sample is poured into a cell from a point above the ultimate liquid level in the cell, the cell is rotated at a speed to blend the liquid while the analysis is performed and then the cell is rotated at a speed to expel the sample from the cell. The cell 14 includes a cup 24 provided with slanting side walls 30 rotatably mounted on shaft 22 of motor 18. In response to a signal from a timer Fig. 2 (not shown) a sampler and diluter are activated so that a sample e.g. human serum and buffer solution are delivered through line 52 and port 50 in electrode holder 16 to cup 24, the tips of sodium ion selective electrode 44, potassium ion electrode 46 and reference electrode 48 being below the level of the sample. The timer then activates a motor control to start motor 18 at a low speed so that cup rotates at 1 to 6 revs/sec to mix the liquid sample, the electrode outputs being measured and recorded whilst cup 24 rotates. After completion of the recording the motor 18 is shifted to high speed by the timer to rotate the cup 24 at 10-15 revs/sec so that the liquid sample is expelled from the cup by centrifugal action and exits from cell housing 38 via port 40. Wall 42 prevents liquid from splashing on to motor 18 and minimises the risk of a ground loop being formed to the motor. Formulae are given for the high and low speeds in dependence upon the angle of slope of walls 30 and the radii of the cup. The floor 29 of cup 24 may be provided with radial ridges or the external cup wall 30 can include air impellor vanes or shaft 22 can carry a fan. The apparatus may be used in a coulometric titration process having a potentiometric end point.

Side thrust resisting means for a longitudinal edge of a conveyer belt 10 comprises an idler endless belt 13 having a substantial coefficient of friction to enable it to move with the belt 10 without slip. The inner face of the idler belt 13 has running contact with the rollers 14 of an idler chain 15 which rotate in contact with walls 16 upstanding from a base-plate 17. Fig. 3 shows how the thrust resisting means is used where the conveyer belt 10 is required to traverse a corner. Those parts of the chain 15 and belt 13 which are out of engagement with the belt 10 are separately tensioned, the belt 13 being engaged by one or more rollers 28 within a cage 29 and the chain being engaged by a side support 24. Nuts and bolts 26 are used to adjust tension.

Title: Improvements in or relating to drawing benches for making conical tubular bodies
IPC: B21C37/18
Filed: 1934-12-13
Abstract: 436,699. Drawing tubes. GROSS, F., 30, Mecumstrasse, D³sseldorf, Germany. Dec. 13, 1934, No. 35812. Convention date, Jan. 22. [Class 83 (iv)] A stationary tube is tapered by pulling along it an adjustable die formed by a pair of rolls 3, 4, Fig. 12, with tapered grooves, the rolls being geared together and coupled, during the drawing stroke, to a pinion 40 moving along a fixed or movable rack 41. The tube 1, Fig. 1, is drawn in stages, first from A to the free end, then from B to the free end and so on. A slide comprising cylinders 14, 25, Fig. 10, and carrying the rolls 3, 4 is advanced by a pump 11 forcing pressure fluid through a conduit 12 and a hollow stationary piston 13 in the cylinder 14, until a stop 15 on the slide engages a first stop A, Fig. 8, on a control 17 which is now carried by the slide towards the end 16, thus compressing a spring 18 to turn a control 21 and push rod 20 toward the head end, which reverses the valves 22 to admit pressure fluid via conduit 23 and through the stationary hollow piston 24 into the cylinder 25. The slide 14, Fig. 10, and rolls 3, 4 now move towards the tail end 26, to reduce the tube to taper, the rolls being rotated by a rack and pinion 42, 40 to which it is coupled by hydraulic pressure admitted automatically on beginning of the working stroke. At the end of the working stroke, the stop 15 engages an annular stop 7 on the drum 17 which is thereby moved towards end 26, compressing a spring 28, Fig. 8, turning lever 21 and moving the control rod 20 towards the end 26, thereby reversing the control valves 22 to admit pressure fluid into the return cylinder 14. To stop the machine after the last draw, the stop 15 also releases the locking device 21 so that the tensioned spring tends to reverse the pump 11 but is prevented by lever 58, Fig. 8, fixed on the control rod 20. Lever 58 strikes an adjustable stop 59 so that the pump valve moves only half its stroke and so prevents pressure fluid from entering the conduit for the return of the slide. If the control drum is turned by the horizontal lever, it frees 58 from 59 and reversal will take place so that the machine can be reversed, stopped or started by the vertical hand lever. A spiral spring 42 returns the rolls to position of maximum pass opening when released.

The gate output drives a series of electronic counters 49, 50 and 51 which is coupled to an accumulator 52 which drives a diode matrix and buffer circuit 53 which in turn drives a read-out section 54 and a visual drill depth monitor 41.
