Title: A rotary surface grinder
IPC: B24B49/00
Filed: 1968-12-11
Abstract: 1,220,280. Grinding apparatus control system. SANSEI MFG. CO. Ltd. 11 Dec., 1968 [12 Dec., 1967], No. 58767/68. Heading B3D. A rotary surface grinder comprises a rotary table 3, Fig. 1, for mounting a workpiece and which is driven by an electric motor 13, a grinding wheel 7 mounted from a column so as to be vertically movable, and a saddle 2 supporting the table 3 and displaceable by a valve-regulated hydraulic cylinder to move the grinding wheel radially relative to the table 3. The electric motor 13 is a D.C. motor which is shunted by a fixed electrical resistance and whose speed is regulated by a solid state Leonard automatic control and by two rheostats one of which determines a variable fundamental speed of revolution and the other of which 16, Fig. 4, superimposes a speed modification so that a substantially uniform linear speed of the table 3 is obtained at the point of grinding, the rheostat 16 being connected in series with the first rheostat and being varied in dependence on the position of the saddle 2 to provide the uniform linear speed, and the valve regulating the hydraulic cylinder also being varied in dependence on the saddle position to correlate the speed of the saddle with the rotary speed of the table. As described the saddle 2 carries a cam 11 which engages with a rack rod 12 and moves the latter as the saddle reciprocates. At its other end the rod 12, Fig. 4, engages with a pinion 43 operating an automatic control valve 15 which controls the flow of oil to the hydraulic cylinder reciprocating the saddle 2. - The rod 12 also engages a segment 42 which controls the second rheostat 16. The arrangement is such that as the saddle 2 is advanced by the hydraulic cylinder so that the wheel 7 approaches the centre of the table 3 the speed of rotation of the motor 13 and hence of the table 3 is increased, and the flow of oil to the hydraulic cylinder is increased so that the linear speed of the saddle is increased. The saddle 2 is reciprocated under the control of limit switches which operate a switch valve in the oil feed line. The wheel 7 falls under a pawl and ratchet mechanism control on each reciprocation of the saddle.

Title: Improvements in, and relating to a filling machine
IPC: B67C3/28
Filed: 1969-12-22
Abstract: 1,255,830. Filling machine. STORK-IMA. N.V. 22 Dec., 1969 [19 Jan., 1969], No. 62354/69. Heading B8T. A filling machine comprises a rotatable liquid tank, e.g. situated above a container supporting table 1 with which it rotates about a vertical axis, having circumferential filling stations with filling valves controlled synchronously with the rotation of the tank by operating members shifted by means of a stationary guide path having two pivotable guide path entry pieces (6, 7), Fig. 2 (not-shown), and a container feed member 4, e.g. a star wheel, having a plurality of locations 5 for feeding containers to the filling stations, each location having a feeler detecting the presence of a container, alternate feelers being associated with a respective impulse member, each impulse member controlling a respective entry piece. The feelers may comprise a spring-loaded short or long pin 9 or 10 respectively, which slides radially inwardly when a container is present. If, however, a container is absent, the pin, which has an end mounted magnet 12 or 13, is not pushed inwardly and passes over a coil sensor 14, 15 which actuates a relay 16, 17 and an impulse member (18), (19), to depress the corresponding entry piece to an inoperative position such that it does not engage the operating member e.g. a roller, so does not open the corresponding container filling valve. The entry pieces may be placed side by side or one above the other and the magnets and coil sensor may be replaced by members which actuate a photo-electric cell sensor or act purely mechanically. More than one feed member may be used.
Patent GB-634324-A (GB)
Abstract: 634,324. Thermally-actuated valves. USHER, J. D., and HOLMES, R. May 22, 1947, No. 13843. [Class 135] In a safety device for gas-heated apparatus, the flow of gas from the inlet 7, Fig. 2, through the tube 12 to the main burners 13 is controlled by a ball-valve 4. On lighting the pilot burner 23, Fig. 1, and depressing the lever 14 against the spring 18, the valve actuating rod 1 is lifted by the legs 16 of the lever so that the bent end 21 of the bimetallic strip 19, which is heated by the pilot burner, enters the groove 2 on the rod and holds it in its raised position. Thus the ball 4 is lifted by the spring 8 to allow gas to pass to the main burner and also to seat on the part 10 of the casing to prevent leakage of gas around the rod 1. Should the pilot burner be extinguished, the end 21 withdraws from the groove 2 and the spring 18, acting through the rod 1, closes the valve.

Title: Spectrophotometer
IPC: G01J3/18
Filed: 1980-02-22
Abstract: A dual beam spectrophotometer includes a radiation chopper (5) and a monochromator (3) which includes a diffraction grating driven by a stepper motor. The chopper (5) includes a gate pulse generator (24) which produces gate pulses GS and GR which correspond to periods during which radiation from the source (2) passes through a sample cell (19) and a reference cell (14) respectively. A stepper motor drive circuit (134) produces pulses to step the stepper motor which are synchronised with the chopping cycle by means of the GR and GS pulses. The stepper motor is arranged to step an equal number of times in each half of a chopping cycle. A further condition which is preferably satisfied is that the first pulse of a sequence should start in the opposite half of the chopping cycle from that in which the first pulse started in a previous chopping cycle. At low stepping rates the motor will step twice in one chopping cycle and then pause for several cycles before again stepping twice. <IMAGE>

Abstract: A releasable connection for a pipe-line or pipe fitting comprises a pair of connection pieces (1, 2), each arranged to be secured to an end of a pipe or fitting. One connection piece (1) includes a recess or groove (1c) to retain a pcking ring (3) against dislodgement, the packing ring (3) projecting out of the groove (1c) so that it is deformed by the second connection piece (2) as the connection pieces are drawn together when being assembled for use. The deformation of the sealing ring (3), which is of an elastomeric material is guided by the shape of the meeting faces of the connection pieces (1, 2) to enter the residual gap between the connection pieces when fully engaged, the engagement being limited by a shoulder formed within a mating recess of one of the connection pieces. The axially outward surfaces of the engaged connection pieces define a pair of conic sections and a split clamping ring (4), embracing the connection pieces, both draws the pieces together and maintains them in engagement. <IMAGE>
