Title: Ball and Raceway Amusement Device
Inventor: MORRIS LOUIS
IPC: A63B67/08
Filed: 1966-12-19
Abstract: 1,165,189. Toy. L. MORRIS. 19 Dec., 1966, No. 56820/66. Heading A65. A toy comprises a pair of spaced apart guide members 12 and 14 forming a guide path therebetween on each side of the guide members on which a ball can roll and includes a widened separation section through which the ball can pass from one guide path to the other, this widened separation section being such that as the ball approaches the point at which it passes from one path to the other the points .of contact between the ball and the guide members shift nearer to points diametrically opposite each other on the ball whereby the rolling movement of the ball is converted to a spinning movement as the ball crosses from one path to the other and the spinning movement is then converted to a rolling movement along the second guide path. As the ball changes 'guide paths the toy must be suitably turned through 180 to retain the ball on the toy. The two rods may be widened at both ends to allow the ball to change paths at either end. A stack of such pairs of rods may be provided so that the ball can be moved from one pair to an adjacent pair or retained on the one pair as it traverses a widened section. The layers may be arranged in a circular manner a rod common to each pair passing down the centre of the cylinder defined by the other 'rods of the pairs. In a further embodiment the guide .paths are arranged in a spiral-; The angle of taper in the widened sections where the ball changes paths should be less than 20. In the embodimerit shown in figure 1 extra rods may be provided to prevent the ball from falling from the toy.

Abstract: 1413998 Reciprocating pumps K-H THOMAS [trading as LANGEN & CO] 11 Dec 1972 [11 Dec 1971] 57068/72 Heading F1A A pump comprises two or more pistons 111, 112 reciprocated in antiphase in cylinders 115, 116 connected by a by-pass line 124 having a valve 125 operable to open or close line 124, opening of line 124 causing liquid to flow to and fro between cylinders 115, 116 with no delivery through discharge line 123. Valve 125 is operated automatically in accordance with the pump delivery pressure in line 123. In Fig.4 (not shown), the valve is a spool valve subjected at one end to the delivery pressure and at the other to a spring-bias, which may be adjustable. A spring-loaded ball engages grooves in the valve spool to hold it in its end positions; the ball spring may be adjustable to vary the differential between the opening and closing pressures. In Fig.2 (not shown), a second valve (225') opening at a higher pressure than valve 125 is arranged in parallel with valve 125, a checkvalve being provided in series with valve 125, so that the pump can operate at full, half or zero output according to the delivery pressure. In Fig.3 (not shown), the pump pistons have through passages (17), (18) which connect the pumping chambers to an inlet chamber (8) at bottom dead centre.

Abstract: 1363469 Automatic control of position ARMSTRONG CORK CO 22 Dec 1971 59803/71 Heading G3R [Also in Divisions B5 and F2] Long lengths of foamed elastomeric tubing comprising foamed plastics 92, Fig. 4A enclosed in a pair 94, 95 of flexible sheaths are constructed on a long mandrel 17 which is fixed at one end, there being control means for detecting and correcting any flexure of the mandrel. The foam 92 comprises polystyrene or polyurethane, and the sheaths 94, 95 comprise paper, foil or plastics sheets. The sheets 94, 95 are lapped and the inner sealed by adhesive, heat, or a hot melt technique when a heat adhesive strip is fed between the lapped edges. Uses include cylindrical or prismatic pipes, ducts or pipe thermally insulating covers. For the latter, the finished tubing is slit longitudinally to form an open side and a hinge (see Fig. 9, not reproduced). General layout. The hollow mandrel 17 is supported at its left end Fig. 1, and, until some tubing is formed, by moulds 52. Flexible sheet material 26 is folded tightly around the mandrel 17 by a guide 25, and heat sealed by an element 25a and roller 25b. Flexible sheet material 30 is folded loosely around the mandrel by a guide 29, and simultaneously foam material is fed by a nozzle 33 into the space between the two sheaths. Foaming and curing is carried out within chair conveyed moulds 52 in an oven, the moulds serving to pull the tubing along the mandrel 17. The flexure of the mandrel is detected by a laser 22 and photo-electric cell 51, which control an aligning device 37. The mandrel; aligning. The aluminium mandrel 17 is supplied internally with warm air 24 that emerges through perforations in the mandrel to aid movement of the tubing. The mandrel 17 with the tubing is engaged by a grooved roller 37 mounted on a spindle 38 and displaceable horizontally and vertically by respective wheel cranks and worms 40, 39. The mandrel internally supports a roller 49, Fig. 7, which opposes roller 37; displacement of roller 37 with respect to roller 49 flexes the mandrel appropriately. An auto reflecting tooling laser 22, Fig. 1, directs a beam internally of the mandrel 17 on to the photo-electric cell 51 comprising a quadratic arrangement X, X', Y, Y', Fig.11. The outputs of opposing pairs XX' and YY' are fed to bridge control circuits 100, 101 that actuate reversible motors 100H, 101V to position the aligning roller 37, Fig. 7, on flexure of the mandrel. Alternatively, the bridge controls 100, 101, Fig.11, deflect meters from zero, the return to zero being effected by manual control of the roller 37 Fig. 7.

Abstract: 1299729 Optical measurement of culture stains TAKEDA YAKUHIN KOGYO KK 23 Dec 1969 [30 Dec 1968] 62676/69 Heading G4H The size of each of a succession of circular stains, produced by the action of an antibiotic on a bacteria culture, is determined by a row of photodectors which scan each of the zones in turn in a direction perpendicular to the row and for each zone a counter counts continuously equi-spaced clock pulses whilst at least any one of the photodectors is scanning the zone. In the arrangement of Fig. 6 two rows of phototransistors I, II scan two successions of zones which are opaque to light from lamps 2, relative to the rest of the culture. Bi-stable circuit 7-I switches at each fresh zone to inhibit alternately to a or b counters of both pairs of counters 9-I, 9-II, whereby during the scanning of a zone in each succession one counter of each pair counts clock pulses from source 8 which are gated via OR gates 6-1, 6-11 while at least any one of the phototransistors are scanning the zone. When no phototransistors are scanning the zone inverters 5-1, 5-II supply an inhibition signal to the counters. The alternate counters when not counting are read-out via control 10 to a tape or card punch 11 and then reset.

Abstract: 717,970. Well points. SHARE, B. Feb. 26, 1952, No. 5000/52. Classes 68(1) and 85. In a well point, means are provided to cause water to issue as a swirling jet from the jetting head of the well point as the latter is sunk into the ground. The suction head 11 and the jetting head 14 are interconnected by a fluted pipe 12, and about the flutes 13 are concentrically secured fine and coarse mesh screens 17, 18. The screens extend between the heads and form with the flutes 13 intake passages 16 that lead into the uppermost of two chambers 26, 27 formed in the jetting head by an apertured partition 22 which forms a seat 23 for a ball valve 20.

On suction being applied to the well point, ball 20 seals the aperture 23 and water is drawn, through the screens 17, 18, down passageways 16 into the chamber 26 and up the pipe 12. The flutes 13 may also be helical. To keep the screens clean during the sinking operation, holes 30 are provided in the lower end of the pipe 12 so that jets of water play thereon. U.S.A.
