[Also in Division B8] A mould for forming a plastics container (1), Fig. 1 (not shown), (see Division B8), by diemoulding, welding and blowing the container forming material extruded in the form of a tube, comprises two shells 10a, and a mandrel 21, each shell including a recess 12a divided by a partition 17a, extending almost its entire length, into two communicating compartments 15a, 16a, the partition decreasing in width, from its base to its top edge, in which is formed a channel 18a which continues as channel 13a to the top edge 14a of the shell, the channels defining a suction pipe (2), (3) of the moulded container. The compartments 15a, 16a are each provided with a channel 19a, 20a to form vent pipes in the container. The mandrel 21 is positioned within the extruded tube, and the shells closed around the tube with channels 19a, 20a, 13a receiving rods 24, 25, and a compressed air entry tube 23, to form the container vent pipes and the external portion (2) of the container suction pipe. Again, Figs. 5-7 (not shown), the inverted mould is provided with two spring, or pneumatic, loaded members (37), (38) which engage the extruded tube (32) before the shells are completely closed, to cause a draping effect (39), and hence provide more material in that portion of the mould which forms the base of the container, to provide the base with thicker walls.

Abstract: 142,815. Arbuckle, S. F. Oct. 16, 1917, [Convention date]. Supporting.-Headlights or reflectors of motorvehicles and the like are so mounted that thev may be tilted downwards to deflect the light from approaching vehicles, by means actuated by the suction in the inlet manifold of the engine.

Filed: 1972-03-16
Abstract: 1375250 Floating point arithmetic unit WESTERN ELECTRIC CO Inc 16 March 1972 [19 March 1971] 12244/72 Heading G4A A floating point word contains a field G indicating the length of the exponent and fraction fields of the word so that a variable exchange between accuracy and number range can be made. A word transferred from memory 20 to a register 22 and a shift counter 24 is preset to a selectable constant C where the number of exponent bits e = G + C. The field G is then transferred to counter 24 and the exponent and fraction fields are transferred to a register 25. The counter 24 controls left shifting of register 25 so that the exponent is transferred to a register 26 and the fraction is left-justified in register 25 for use by a conventional floating point arithmetic unit 21. Conversely, when a normal floating point word is obtained from arithmetic unit 21, counter 24 is preset to reach zero after C shifts, the exponent and fraction in registers 26, 25 are right shifted until the register 26 is empty, and the contents of counter 24, now equal to G, are transferred to register 22 together with the exponent and fraction from register 25.

Title: Pick-up head for an optical correlation velocity meter
IPC: G01P3/80
Filed: 1973-03-14
Abstract: 1417881 Photo-electric velocimeters HASLER AG 14 March 1973 [6 April 1972] 12312/73 Heading G1A In an optical velocimeter for a rail vehicle using the correlation of signals produced from two points of a stationary surface over which the vehicle moves, the optical system is arranged so that the fields of view of the detectors comprise areas which in the direction of travel are sharply defined and narrow in comparison with the distance between them, and transversely to the  direction of travel are broader and not sharply defined. As shown, Figs 1a and 1b, the scanning head comprises two sources 6, 6 which illuminate areas of the rail 3 via optical systems comprising crossed cylindrical lenses 7, 8, 7 , 8', further cylindrical lenses 13, 13 and spherical lenses 16,16'. The beams produced are parallel in a plane parallel to the direction of motion 5, Fig. 1a, but diverge in the transverse plane, Fig. lb. In the system illustrated three points 4, 4'and 4"are scanned, the area surrounding points 4'and 4" being illuminated by a single beam and enabling measurements of low accuracy to be made, while correlation of the signals from points 4 and 4' allows high accuracy measurements. If desired the system illustrated in the left hand portion of Fig. 1a may be used alone. Light reflected from the scanned points is directed by lenses 13 and 16 (13 and 16") on to photo-detectors 20 positioned on member 10 above slits which extend transversely to the direction of motion, radiation from a point 19 on the rail being brought to a line focus on the detector by the lenses. This ensures that each scanned area is narrow and sharply defined in the direction of motion but broader and more diffuse transversely to the rail. This reduces the effects of changes in relative angle of the rail surface, e.g. caused by lateral movement of the vehicle relative to the rail, which would otherwise cause large variations in the amount of light reflected to the detector. The signal from the leading detector is delayed to correlate it with that from a second detector, the delay time being proportional to the velocity of the vehicle. Entry of dust and moisture into the measuring head may be prevented by directing a stream of air out through apertures 2, 2' during motion.

Abstract: 1314766 Measuring fluid-flow FOXBORO CO 30 April 1971 [30 July 1970] 12416/71 Heading G1R In a differential pressure type fluid flow meter, a streamlined Venturi nozzle 16 is provided with a series of tap holes 20 joining the throat 19 to an annular recess or channel 21 in the outer wall of the nozzle, the recess defining with the pipe 11 an annular cavity with which downstream pressure tap line 15 communicates. As in Fig. 5 (not shown) the nozzle may be extended downstream in a gradually expanding taper. By providing the nozzle with an annular flange 17, it may easily be substituted for an orifice plate. In use, the nozzle provides that the noise pattern at upstream pressure tap 14 is duplicated at the downstream tap 15 thus enacting the differential pressure measurement device to which the taps 14, 15 are connected to balance the noise patterns against one another and thereby substantially cancel them out.

Addressing-machines ; inking-apparatus. - A machine for addressing envelopes, labels &c. comprises a box or case having a drawer for storing stencil cards, a magazine for holding stencil cards ready for use, a track or slideway secured to the top of the case, a hand-operated slide movable in the slideway for acting on the stencil cards, and an adjustable gauge for the envelopes, the major part. of the inking mechanism being housed in a compartment situated at one end of the box. The stencil cards 3 to be used are taken from the drawer 2 and placed in a magazine 6 formed of two vertically arraned channel members. A slide 9, movable in a slideway 5 by a rod 8 fitting in an extension of one of the vertical channel members which are flanged over for this purpose, engages with the lowest stencil card in the magazine 6 and pushes it along the slideway 5 until it reaches a segmental presser roller 18. This roller 18 is mounted on a hand-operated shaft 16 having a bearing in a lug 14<a> upstanding from a casting 14 secured to the underside of the top of the box. A gear wheel 20, mounted on the shaft 16, engages with another gear wheel 21 on a shaft 22 mounted in the casting 14. To address an envelope, a segmental inking roller 23, carried by the shaft 22, is adapted to coact with the segmental presser roller 18 and feed a stencil card and the envelope forward between them. The segment roller 23 is inked by a hand-rotated metal roller 24 carried by arms 25 pivoted to the casting 14, springs 29 normally keeping the rollers in contact. The roller 24 is lowered out of engagement with the roller 23 by a cam 33<a> operated by a handle 33 and engaging short arms 32 attached to the arms 25. A felt reservoir roller 28, which is inked by hand, is carried by arms 27 pivoted to the casting 14 and spring-pressed into contact with the roller 24.
