Title: Mechanically driven mixer
IPC: A61C5/68
Filed: 1964-11-04
Abstract: A mixer for dental fillings having a reciprocating, oscillating or vibrating container such as is described in Specification 975174 has a roller (24) with metering pockets (24a) secured to a shaft on which are fixed also a knob (25) and a wheel (51) with notch (50) into which can enter the end of the core (52) of a solenoid (53).

The lower bead of the bladder is clamped between rings 7, 8 and its upper bead between rings 12, 13 vertically movable relative the lower rings by being supported on a piston-rod 3 of a piston 2 slidable in a cylinder 1 supplied with hydraulic fluid through inlets 23, 23<SP>1</SP> and 24. The segment plates are mounted on and radially slidable relative to the ring 13; a plate 17 is held by bolts 26 which engage slots in the segment plates. Radial movement of each segment plate is controlled by a cam 20 connected to the plate and pivoted to the ring 12 at 20<SP>1</SP>; the lower end of each cam engages a groove in a sleeve 19 at the top of a piston-rod 5 of a piston 4 so that relative movement of the pistonrods effects radical movement of the plates. After curing, the piston 2 is lowered causing the plates to engage beneath the upper bead of the tyre, whereupon the upper mould part and the pistons 2 and 4 are raised to effect erection of the bladder and the stripping of the tyre from the lower mould part. The tyre is retained by thee segment plates which are then retracted by lowering the piston 4 enabling the tyre to be supported from underneath by lifting arms, not shown. Instead of a series of cams 20 the segment plates may be operated by a single conical cam attached to the piston-rod 5.

Abstract: 1517285 Automatic control of drawing BKS SURVEYS Ltd 8 May 1975 48346/74 Heading G3N A plotting point is moved between a plotting and a non-plotting position to produce a line having a pattern of pre-selected form independent of the plotting speed, a signal representing the plotting speed being used to produce a further signal controlling the plotting non-plotting movement. As shown, vector adding circuit produces a voltage representing the actual speed, which is converted to a corresponding frequency in converter 7, the resulting impulses being converted to square pulse form in pulse shaper 8, wherein they pass to a counter with decimal output, there being a correspondence between the decimal count and the state of a relay controlling the plotting non-plotting movement. The correspondence may be established by an array of switches or a single multi-pole switch, or logic elements or a computer may be used. Patterns are typified in Figs. 4a-c, (not shown). Optical encoders for X and Y components of motion of a plotting point supporting carriage provide signals of frequencies proportional to such components, which frequencies are converted in units 4, 5 to corresponding voltages, which, in vector adding circuit 6 are each squared, then added, the square root of the resultant being extracted to produce the voltage representing the actual speed.

If the carriage traverse rope 6 of a tower crane breaks, a member 27, which supports a wedge 28 of hard-wood, is allowed to fall and becomes jammed between an eccentric wheel 36 and a bracket 24 thereby arresting the movement of the carriage 3 towards the outer end of the jib under the weight of the load. The wheel 36 is fast with the sheave 11 which is turned clockwise by a hoist rope 10 when the carriage moves towards the outer end of the jib. The periphery of the wheel 36 is toothed or knurled to enhance the grip on the wedge 28. The rope 6 passes through an eye in the top of the member 27. Winching in the hoist rope 10 will cause the carriage to move inwards and the load to be raised. The wheel need not be eccentric. The hoist rope may extend from the sheave furthest from the tower to an anchor and from the sheave nearest to the tower to the hoisting gear, the brake being arranged to act on the outer sheave.
