Abstract: 1287951 Flexible tube pumps RAINBOW VALVE CO Ltd 12 June 1970 [12 June 1969] 29714/69 Heading F1F In a peristaltic pump, liquid is pumped through a flexible tube 6 by a presser 7 in combination with inlet and outlet pressers 23, 24, each presser squeezing and releasing the tube 6 in sequence, the pressers 23, 24 functioning as non-return valves. The pressers are mounted on spring- pressed levers 11, 25, 26 which are sequentially rocked about a common shaft 12 by rotary cams 17, 29, 30. The output is varied by means of a screw rod 19 engageable with the lever 11 to limit its rocking motion. The presser 7 has a transverse rib 10, which is the only part of the presser which contacts the tube 6 at minimum output. An eccentric 35 on a shaft 36 may be rotated through 180 degrees to act on the levers 11, 25, 26 to disengage all three pressers from the tube 6 to allow removal of the latter from the pump. In another arrangement, Fig. 8, the levers 11, 25, 26 have extensions on the side of the shaft 12 remote from the tube 6 and the cams 17, 29, 30 are arranged to act on these extensions. The tube is released for removal by rotation of cams 45, (46, 47) Fig. 9 (not shown), the cam 45 being profiled to also provide the output variation. To facilitate its removal, the tube 6 may be mounted on a U-shaped former separable from the remainder of the pump, Figs. 6 and 7 (not shown).

Abstract: 1288364 Grinding VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY INSTRUMENTALNY INSTITUT 3 Nov 1970 52109/70 Heading B3D A machine for grinding grooves in round articles 5, such as drills, reamers, taps and shank cutters, comprises a bed 3 on which is mounted a grinding stone 1 and a reciprocatable carriage 7, an auxiliary bed 6 articulated to the carriage for making periodic turns around an axis 23 perpendicular to the direction of movement of the carriage, a work spindle 4 mounted on the auxiliary bed, a cam-shaft 27 mounted on the carriage and having a cam 24 which interacts with the bed 3 to move the carriage, and a motor 13 and gear train on the carriage for driving the carriage, auxiliary bed, spindle 4 and cam-shaft 27. The arrangement is such that the auxiliary bed carries only a few parts and hence its movement does not apply large loads on the machine. The carriage 7 is supported for movement on the bed 3 by rollers 9 and is guided by a pin 52 and slot 8. Brackets 10 on the carriage support a shaft 23 carrying the auxiliary bed 6, the shaft  being formed with a worm 11 engaging a wheel 24 secured to the spindle 4 carrying the workpiece 5 which is supported on a block 56. The shaft 23 is driven by gearing 21, 22 from a shaft 20 mounted in a casing 12 on the carriage 7 and rotated by gearing 18, 19 and belt-drive 16 from the motor 13, the shaft 20 also driving through a worm and wheel 25, 26 the cam-shaft 27. The latter has a pair of cam faces 29, 42. Cam face 29 coacts with a follower 30 which is slidable in an upright 32 and has a disc 34 engaging a roller 35 on a lever 36 at one end connected by a pivot 37 to the carriage 7 and at the other end adjustably connected to a stop 38 formed with a roller 41 acting against a guide 39 on the bar 3 whereby the carriage is reciprocated with an amplitude determined by adjustment of the stop 38. The cam face 42 is engaged by a follower 43 on a slide 44 having a projection 45 engaged by a roller 46 on the auxiliary bed 6 whereby after a stroke of the carriage in one direction to grind a groove in the workpiece, the bed is swung downwardly to disengage the workpiece from the grinding wheel for the return stroke of the carriage. The machine is adapted for grinding both straight and curved grooves and the workpiece may be indexed by a Geneva cross mechanism. Move. ment of the auxiliary bed during movement of the carriage produces grooves of variable depth.

As shown, the applicator is in the form of a cylinder having a piston 126 connected via a rod 76 and a plate member 78 to a cam follower 74. A cam 50 and a cam carrier 48 rotate freely about a shaft 52, a pin (66) Fig. 4 (not shown) mounted on cam 50 engages an arcuate slot (66) provided in cam carrier 48, and a pin 60 mounted on cam carrier 48 engages a circular recess (58) provided in a spur gear (56). A motor 38 drives the spur gear via a reduction gearing (54) and a timing belt 42, a driven shaft 40 of the gearing terminating in a spline which couples to a take-up spool of a film cartridge (not shown). The film is driven at a constant speed by coupling a potentiometer 170 to cam 50, the potentiometer being in the motor circuit so as to adjust its speed as film builds up on the take-up spool. The apparatus is disposed in a light-tight housing, the film cassette being loaded through a hinged door provided in one wall of the housing.

Abstract: 1290936 Damped spring units UNITED STATES ATOMIC ENERGY COMMISSION 19 Nov 1970 [10 Dec 1969] 55002/70 Heading F2S [Also in Divisions G1 and H1] A "roller-band device" of the type described in Specification 1,181,636, when used as an inertia switch, has its housing 12 filled with a damping fluid 79 at a temperature above its desired range of operating temperatures, such that when the sealed housing cools a vapour or vacuum bubble 80 is formed in the housing. The size of this bubble changes with temperature over the desired range to help keep the damping force on the roller-band cluster 10 fairly constant. Roller 14 is solid, whilst roller 16 is spool-shaped with ring 15. The tensionband 18 includes an elongated orifice 58 for metering damping fluid, e.g. silicon oil and a forcebiasing opening 60 to normally bias the cluster 10 against end wall 28 away from the end wall 30 carrying the fixed, bifurcated contact 50 engageable by band 18 to complete the inertia switch circuit. Fill opening 42 is sealed once fluid 79 is in the housing 12.
