Filed: 1925-08-04
Abstract: 263,509. Moir-Buchanan Centrifugal Processes, Ltd., and Ure, C. M. Aug. 4, 1925. Centrifugal machines; moulds. - A rotatable and longitudinally separable mould for the manufacture, centrifugally, of pipes, columns and the like having branches is provided with peripheral pockets 6, 7 which are non-divided and hence not affected by the separation of the mould parts 1, 2. For the purpose of producing hollow branches a removable former 9, Fig. 5, is employed in the pocket. The former does not enter the mould beyond the surface which represents the exterior of the pipe or the like. In practice, the cavity around the former is first filled, as by hand trowelling. Then the material for the pipe is distributed along the axis of the mould while this is spinning. After the material has set and the former removed, the membrane of material separating the interior of the branch from the interior of the main pipe is cut away. The former 9 is removed by inserting a cross-bar 12 beneath two ledges 11 thereon. A nut 17 is then screwed on a bolt 14 secured to the cross-bar and passing through an external bridge piece 15. As the nut is screwed up, the former is withdrawn. In moulding a pipe with a single branch, one pocket is kept filled with concrete to constitute a dummy and preserve the necessary centrifugal balance when the mould is spinning.

Patent GB-198434-A (GB)
Abstract: 198,434. Odhner, V. J. March 2, 1922. Multiplying and dividing apparatus; zeroizing- mechanism.-In a machine of the cam-disc and pin-wheel type for calculations according to the four rules, a Geneva wheel connected with a numeral wheel is provided for each pin-wheel and co-operates with a slot in the periphery of the pin-wheel and a locking member normally covering said slot whereby the numeral wheels can be zeroized only when the pin-wheels are in their normal positions. Means are also provided on the totalizing-counter carriage so that on the movement of the latter to the right, those numeral wheels which are beyond the remotest pin-wheel are locked against accidental rotation. Each pin-wheel 2, Fig. 1, has a slot 9 in its periphery covered by a member 11 pivoted at 12 to the pin-wheel and acted on by a spring 13; and each numeral wheel 4, carries a pinion 5 meshing with a gear wheel 7 attached to a Geneva wheel 8 which is located opposite the slot 9 when the pinwheel is in its normal position as shown in Fig. 1. A projection 14 on the member 11 co-operates with a cam 19 connected with the shaft 3 of the numeral wheels by the train 16, 17, 18, the cooperating faces being so formed as to allow the pin-wheels to be rotated without hindrance. To zeroize the numeral wheels the shaft 3 is rotated and moved in the known manner, thus rotating the cam 19 so that it moves the member 11 inwards towards the centre of the pin-wheel, to rotate therein. In the construction shown in Fig. 4 the member 11 moves radially in a guideway 21 in the pin-wheel; and in that shown in Fig. 5, the member 11 moves peripherally on the pin-wheel by means of guide-ways 22 in it. In the modification shown in Fig. 6 the member 11 is moved in a direction parallel to the shaft 1 of the pin-wheels, the cam face being formed on the side of the cam 19. If the totalizing-counter carriage 10 is moved to the right so that, for example, two of the numeral wheels are beyond the remotest pin-wheel 2, as shown in Fig. 2, the two - corresponding Geneva wheels are no longer locked by the members 11 but they are locked by the following mechanism; a shaft 30 on the carriage 10 carries a lever 31 for each numeral wheel, the inner ends of the levers 31 contacting with a surface 33. Directly a numeral wheel and therefore its lever 31 have moved to the right past the last, i.e, units, pin wheel, the inner end of the lever moves down the bevel 34, Fig. 2, and the outer end is moved up by a spring 36 so that a projection 32 on the lever locks the pinion 5 of the corresponding numeral wheel. In a modification, Fig. 14, a similar bevel surface releases pins 38 and in another modification, Fig. 18, levers 31, 46 are moved in an horizontal plane so that the projection 32 locks in the pinion 5.

Filed: 1945-08-04
Abstract: 596,933. Differential gearing. ELLIS, E. D. Aug. 4, 1945, No. 20118. [Class 80(ii)] [Also in Group XXXI] In an endless-track vehicle driving and steering mechanism the tracks are normally driven through a single cross-shaft, a normal differential and half shafts, and steering is effected by means of a direct drive from one end of the cross-shaft to one of the half shafts so that the engine drives the half shafts at different speeds; a clutch is provided at each end of the cross shaft for this purpose. The Figure shows a driving shaft 1 with a bevel wheel 2 in engagement with another bevel wheel 3, the latter being keyed to a cross shaft 4. A pinion 6 also keyed to the shaft 4 drives a differential cage 11 through a toothed ring 7. The differential drives half shafts 9 which are in turn connected to the track sprockets 12 through gear wheels 13, 14. The cross shaft 4 has, attached at each of its ends one element 15 of a friction clutch, the other half 16 of which is integral with a gearwheel 17 and is free to turn on the shaft 4. Steering is effected by these clutches engagement of one of which causes the gear 17 to drive a meshing gear 20 keyed to one half shaft 9. This direct drive causes the appropriate half shaft to speed up or slow down relative to the differential speed, depending upon the difference of gear ratios between the wheels 17, 20 and the wheels 6, 7 a factor which determines the turning speed of the vehicle.

Filed: 1944-10-18
Abstract: 600,255. Pulse modulation. STANDARD TELEPHONES & CABLES. Ltd. Oct. 18, 1944, No. 20199. Convention date, May 24, 1943, [Class 40 (v)] A blocking oscillator is triggered by incoming carrier frequency pulses to produce corresponding D.C. pulses and to control a flip-flop multivibrator circuit. The output of the latter may be fed back to the oscillator to increase its sensitivity during the oscillating interval. In one embodiment time-modulated pulse radio signals in the aerial coil 18, Fig. 2, initiate oscillations in the circuit L, C which build up and are sustained by the valve 23 until the charge on condenser 26 becomes negative enough to inhibit oscillation. Thereafter the charge leaks away through resistances R1, R2 at such a rate that the next received carrier pulse can trigger the oscillator again. The free-running pulse recurrence frequency is adjusted by the screen supply potentiometer 32 so that it is lower than the meansignal pulse recurrence frequency. The voltage pulse at the anode triggers a flip-flop multivibrator (not shown) which produces output pulses of fixed amplitude and duration for the time modulated pulse demodulator which may be of the type described in Specification 600,291. A multivibrator pulse is fed back to the grid of valve 20, over the lead 37 to the junction of resistances R1, R2 during the oscillation period. The demodulator may alternatively be fed from the rectified voltage impulses in the blocking oscillator circuit.
