Title: Drinking device for bottles and similar containers
IPC: A61J11/00
Filed: 1976-09-24
Abstract: 1523217 Drinking nozzle ALTO AS 24 Sept 1976 [26 Sept 1975] 39810/76 Heading B8T In a drinking nozzle for, e.g. a bottle, valve body 11 is attached via stem 12 to membrane 4, the space 9 beneath membrane 4 being subject to atmospheric pressure via channel 10. When suction is applied to mouthpiece 1, valve body 11 is lifted off seat 7 and liquid flows from container 14 via ports 6 and through mouthpiece 1. The pressure decrease thus produced in space 5 acts, in combination with atmospheric pressure below membrane 4, to raise the membrane and thus maintain the valve body 11 off its seat at the cessation of suction to allow air to enter the container through the valve to replace the liquid discharged.

[Also in Division B7] In a self-propelled lift-truck which is steered and controlled through a tiller by a pedestrian operator and includes an emergency switch which automatically reverses the truck should contact with the operator's body or other obstacle depress a yieldable section of the tiller, the maximum displacement of the yieldable section corresponds to the overrun distance travelled by the truck in the time taken for reversal to become effective. The yieldabe section 36 of the tiller carries a control head 4 and telescopes against a spring 39 by an amount permitted by a pin-and slot connection 43, 44 when the pressure thereon exceeds a predetermined limit set by a retaining spring 42. The emergency switch 46 is actuated by a member 45 on the yieldable section 36 and is connected to a motor control circuit (Fig. 8, not shown) including relays which limit the duration of reverse travel and require that the normal travel control be restored to the stationary position before forward travel can be resumed. In Fig: 2 (not shown) the emergency switch (21) is actuated through a rod (32) from a spring- loaded safety member (20) projecting from the control head. In Fig. 7 (not shown) the safety member is displaceable only by an amount sufficient to operate the switch, telescopic compression of the tiller absorbing the residual motion of the truck. The switch may be so actuated that initial depression of the safety member interrupts forward travel and reversal occurs when the safety member is fully depressed. In Fig. 5 (not shown) one of emergency switches (51) is actuated upon pivotal displacement of either of two handles (47, 48) projecting laterally from the control head. The handles (47, 48) pivot against spring loading only when sufficient force is applied thereon to release a retaining spring (56) or fracture a pin at a predetermined loading.

Title: Improvements in or relating to spectrum analysers
Inventor: CROSS MALCOLM GEOFFREY

Filed: 1970-09-04
Abstract: 1299023 Spectrum analysis MARCONI CO Ltd 10 June 1971 [4 Sept 1970] 42375/70 Heading G1U A spectrum analyser of the type in which a reference signal having a cyclically swept frequency 3, Fig. 2, is mixed 2 with an unknown signal 1 to produce a signal, each sweep of which will start to pass through the range f 2  to f 3  at a time determined by the frequency f of the unknown signal 1 (assuming that this signal consists of only a single frequency), which signal is applied via a band pass filter 6 to a dispersive delay line 7 designed to collapse the sweep from f 2  to f 3  to a single instant (i.e. the difference #t 2  in the delays introduced by the line to frequencies f 2  and f 3  is equal to the time taken for the reference signal to sweep through the range f 3 -f 2 ), is characterised in that the cyclically swept reference signal is produced by applying narrow pulses to a band pass filter 8, Fig. 3, to produce a continuous spectrum of frequencies, which spectrum is distributed in time by a dispersive delay line 9. Thus a succession of frequency sweeps are produced by the delay line 9 and in order to bring these to the desired range it may be necessary to shift their frequency by a local oscillator 11. In the prior art arrangement, Fig. 2 the frequency sweeps were necessarily non-overlapping if a single oscillator was used, and this resulted in inefficiency in that if the total sweep time was #t<SP>1</SP>, the period over which the signal from the mixer 2 could start to enter the band f 2  to f 3  was only #t 1 , where #t<SP>1</SP> = #t 1  + #t 2 . In other words, the resulting output signals 5 were always spaced apart by #t 2  which was thus effectively wasted, whereas in the arrangement according to the invention the pulses applied to the filter 8, Fig.3, can be spaced apart by #t 1  so that as a result successive frequency sweeps produced by the line 9 overlap each other by a duration #t 2  and no time is now wasted.

Abstract: 1,178,335. Film storage and supply devices. FOTOCOLOR AUTOMATION Ltd. June 25, 1968 [Sept. 18, 1967], No.42388/67. Heading G2A. The invention comprises a magazine for storing exposed film strips preparatory to feeding them to a processing machine. The magazine is built up on a rectangular framework of bars 4, 5, 6. Along each side is a fixed horizontal plate 9 and a parallel movable plate 13. At one end of plate 13 is a slot 14, in which a pin 15 on plate 9 engages. Thus plate 13 can have both a rotational and sliding movement about pin 15. This movement is imparted to it by a crank arm 16, rotating about a pivot 17 on plate 9, its other end pivotally attached to a pin 18 on plate 13. Thus as crank arm 16 rotates, the adjacent end of plate 13 executes an up and down, as well as a longitudinal, movement. Three stages in this movement are illustrated in Figs. 4-6 (not shown). The rods 10, to which the film strips are attached, are first placed on hook members 12 until the film loading is completed. They are then laid in notches 11 in plates 9, and the movement of plate 13 relative to plate 9 causes them to be pushed slidingly along in intermittent steps until they reach an inclined ramp 28, where they remain until they can be loaded into a processing machine. The rods may have spacing collars 19 at their ends.

Title: Process for the removal of alkynes from hydrocarbon mixtures containing alkadienes
IPC: C07C7/00
Filed: 1963-10-31
Abstract: Alkynes are removed from alkadienes e.g. butadiene or isoprene by separating a fraction having an increased alkyne: alkadiene ratio and subjecting this fraction to selective hydrogenation. The separation may be effected by rectified absorption using dimethylsulphoxide as solvent or distilling in a column preferably having 80-160 trays and removing an alkyne concentrate as a side stream in the lower third of the column.  Hydrogenation may be effected in the gaseous, trickle or liquid phase over nickel, cobalt, chromium, magnesium, vanadium, iron oxide or, preferably, palladium on alumina or silica.  The hydrogenation need not effect complete reduction of the alkyne and the product may be recycled to join the feed to the primary separation or to the distillation column at a point below the side stream withdrawal point.
