Abstract: A terpolymer comprises at least one polysiloxane block, linked to at least one polyoxyalkylene block and, attached to a polyoxyalkylene block, at least one polyvinyl ester or partially or wholly hydrolysed polyvinyl ester block.  The vinyl ester, e.g. vinyl acetate, propionate, butyrate or caprate, is grafted, using a free radical catalyst, on to a polyoxyalkylene of general formula (OCnH2n)x where X is an integer and n is from 1 to 5.

Abstract: 1367800 Grinding machine control TOYODA KOKI KK 24 Nov 1971 [19 Dec 1970] 54629/71 Heading B3D  A grinding machine comprises a bed 40 slidably bearing a wheelhead 6 for a grinding wheel 42 and a table 5 for a workpiece W, means 44 for relatively feeding the wheel 42 and workpieces W, means 10 for detecting, and producing a signal proportional to a grinding resistance exerted on the wheel 42, a system 3 for calculating an optimum grinding resistance according to the output of programmed control means 2 and means 1 for generating a signal proportional to the volume ground from the workpiece W, and means 6a for controlling the relative feed to maintain the grinding resistance at the optimum value. The grinding resistance may be sensed by detecting the pressure differential between opposite pockets of an hydraulic bearing of the wheel 42, and a dressing device 8 is mounted on the wheelhead 6, compensating means 12 actuating a screw 45 to compensate for wheel reduction on dressing. A work spindle (not shown), on the table 5 is driven by an hydraulic motor 7b at a speed controlled through a servo-valve 7a by the system 3 in accordance with the control means 2. The workpiece diameter is sensed by a sizing device 9, Fig. 6, including an upper feeler 41a movable under gravity on a guide 61 and a lower feeler 41b movable upwardly on a rod 65 slidable in bushes 67, 68 under the action of a weight 74, a magnetic scale 72 rigid with the rod 65 cooperating with a reading head 73 rigid with the feeler 41a to produce a sizing signal. In operation, with the wheel 42 in an initial dressed condition, the feelers 41a, 41b are moved into engagement with the workpiece W, and the wheelhead 6 is fed by a pulse motor 6b until the grinding surface of the wheel 42 is spaced from the workpiece W by half the measured diameter of the latter. The wheel 42 is then fed into the workpiece W until its diameter reaches the required valve, whereupon the control means 2 causes retraction. While grinding cycles are repeated, an accumulator circuit (37), Fig. 3 (not shown), of the system 3 sums a parameter indicative of the volume of material removed by grinding, derived by an operating circuit (36) from the difference between the initial and required diameter of the workpiece W, thus giving the signal proportional to the extent of grinding. When this total reaches a preset figure, a comparator (38) acts to initiate a further dressing cycle, whereupon the accumulator (37) is reset for a further series of cycles.

Abstract: 1408587 Photo-electric line followers HITACHI Ltd 29 Nov 1972 [30 Nov 1971] 55159/72 Heading G1A [Also in Division G3]  A vehicle is automatically steered along a guide path by light, from a source on the vehicle, reflected back from the guide path to a plurality of light detectors across the vehicle, a steering control signal that varies in steps according to the vehicle steering position relative to the guide path being formed from a combination of the outputs of the detectors. As shown, the vehicle position relative to a guide path 23 is measured by seven discrete detectors 19 e.g. CdS cells, photo transistors or photo diodes, each provided with a hood positioned across the vehicle, and which respond to light from lamp 17 that is reflected back from the guide path, for example white paint or tape, or aluminium tape. Using a magnetic amplifier and logic elements, the detectors operate relays to vary the field excitation of steering motor 7, from battery 15, in steps according to the difference between the measured vehicle position and the guide path 23. At marks on the path which divide the path into sections, all detectors simultaneously produce an output to indicate that a certain section has been entered, the vehicle operations in this section being controlled by a programmed sequence controller e.g. by steering left or right at a fork, or stopping the vehicle for loading or unloading. Similarly, outputs from only three detectors simultaneously allow the vehicle to pass straight through the section.
