Title: Lifting apparatus for bags, cases and the like
IPC: B66F9/02
Filed: 1945-11-15
Abstract: 600,342. Load-handling apparatus. REICHARDT, H. C. Nov. 15, 1945, No. 30587. Convention date, Dec. 21, 1942. [Class 78 (iii)] In apparatus suitable for lifting loads to shoulder height, and comprising a platform 1 on a carrier 2 movable up and down guides 12 by a reversible electric motor 22, stopping of the motor at the limit of travel in either direction, as well as reversal and automatic starting on loading or unloading the platform, is effected by a control rod 7 extending the length of the guides and fitted at either end with tappets 6, 17 for actuation by a cam 5 on the carrier 2. The platform is pivoted at 9 to the carrier and connected through a link 3 and arm 4 with the cam 5 which has a vertical pivotal mounting on the carrier. When the carrier is loaded in its lower position, it tilts slightly about pivot 9 against return springs 8, and this rocks cam 5 and hence tappet 6 and control rod 7 to switch-on the motor. When the platform reaches the upper limit, cam 5 engages tappet 17 to turn the control rod back to stop the motor. When the load is removed, the platform tilts back on pivot 9, cam 5 is returned and this turns the control rod further back to reverse the motor and return the platform ready for a further operation. The tappet 17 is adjustable along the control rod so that the upper limit of travel can be varied. There is also described an adjustable connection between the platform 1 and cam 5 so that the apparatus can be readily altered for similarly lowering loads. The driving chain 13 is connected to the carrier 2 by a catch which slips on overload.

Title: Flame detection apparatus
IPC: F23N5/08
Filed: 1975-10-09
Abstract: 1488166 Flame sensor SPECTUS OIL BURNERS Ltd 9 Oct 1975 [10 July 1974] 30615/74 Heading G1A A photo-electric flame sensor comprises a photo tube P, receiving radiation from a flame, connected in series with a resistor R3 across an A.C. source 1, 2, whereby, in use, bi-directional voltage pulses are generated across resistor R3 and are coupled to fire a gated bi-directional semi-conductor switch T i.e. a triac, pulses appearing across resistor R 2  connected in series with T, being rectified, BR, and the mean output voltage of the rectifier being used to provide an indication of the presence/absence of the flame or of a defect in the apparatus. Further defect indications may be provided by monitoring the average voltage across R2. In the arrangement described, ultraviolet radiation between 0À15 and 0À2 Á in the flame root is monitored by a gas-filled photo-tube, having symmetrical electrodes and a quartz envelope. Arc discharge is obtained at the peaks of the mains supply waveform and the sharp pulses are transmitted by C3 and R 4  to the triac to the exclusion of mains signals. Since the triac is powered by the mains in synchronism it is gated by the flame pulses at the peaks of the supply and conducts until the end of each half cycle to fill the waveform of Fig. 2A (not shown). The triac load resistors include R 1 , made up of a number of resistors for heat dissipation efficiency. The rectified output across R2 is used to hold relay RA on for flame presence. By also monitoring the voltage across R 2  (terminals AB) using an A.C. voltage meter which measures the average waveform value, a variety of defects may be indicated. If full scale deflection is 0À64 of the peak voltage Vpk across R 2 : a zero reading will indicate: (a) loss of flame, (b) short-circuit of photo-tube, (c) open circuit of triac or photo-tube (d) mains failure. (Mains voltage is not transmitted by C 3 , R 4 ); full scale deflection indicates short-circuit of triac; ¢ F.S.D. to F.S.D. indicates a "soft" phototube; 0 # ¢ F.S.D. (fluctuating) indicates normal flame. For defects in which zero output is produced the relay RA will drop out. The meter may have an alarm circuit for providing an aural and visual alarm and can be connected to ED (normally closed) to operate the relay F appropriately.

Title: Continuous process of recovering pyridine bases from acid salt solutions which contain the same
Filed: 1948-11-26
Abstract: <PICT:0657567/IV (b)/1> Pyridine bases are recovered from acid salt solutions thereof by a continuous process in which a flow of the acid salt solution is neutralized continuously and the pyridine bases liberated are removed by steam distillation, whereupon the aqueous solution of said bases obtained as a condensate is saturated with a salt readily soluble in water and the liquid layer containing the pyridine bases is separated.  The pyridine bases are those present in the crude gas formed in the coking of coal and comprise pyridine and its homologues such as picoline and lutidine as well as other heterocyclic nitrogen compounds such as quinoline.  The process has particular utility for the recovery of pyridine bases from the ammonium sulphate-sulphuric acid saturator liquid obtained from a by-product coke-plant.  The neutralisation may be effected with liquid ammonia or an aqueous solution of ammonia. In the drawing, a flow of preheated saturator liquid which is saturated with sulphate of ammonia and which contains free sulphuric acid and pyridine bases in the form of salts passes through pipe 1 into a wider pipe 2 where it is neutralized to a pH of substantially 7.0 by liquid ammonia supplied through pipe 3 while at the same time water is supplied through pipe 4 to prevent too much sulphate of ammonia crystallizing and causing obstruction to the flow.  The neutralized solution at a temperature of about 85 DEG  C. flows into the extractor 7 into which steam is admitted through pipe 17.  The vapour leaving the extractor should have a temperature of 95-96 DEG  C. to remove all the pyridine and is condensed in the cooler 9 from which an aqueous solution of pyridine passes to the saturator 11 where it is pressed upwards through a column of solid sulphate of ammonia.  The emulsion of pyridine in a saturated solution of sulphate of ammonia passes into the vessel 13 from which the top layer comprising pyridine is discharged through pipe 14 whereas the bottom layer is returned to the saturator in conjunction with the solution which flows from the bottom of the extractor 7 through pipe 16.  U.S.A. Specifications 1,274,998, 1,414,441 and 2,311,134 are referred to.  The Specification as open to inspection under Sect. 91 states that ammonia gas may also be used for the neutralisation step.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1380003 Jet impingement heat exchanger THERMO ELECTRON CORP 3 July 1972 [23 July 1971] 31014/72 Heading F4S Jets of heat exchange fluid from a plenum chamber 70 bounded by a wall 62, impinge on a heat-transfer wall 60 from apertures 66 in the wall 62, at least one of said walls being corrugated and the apertures 66 being disposed in areas of the wall 62 which are relatively nearer to the wall 60 than are the remaining areas of the wall 62. As shown, the jets may be applied on both sides of the wall 60 (i.e. for both heat exchanging fluids). The arrangement provides relatively large channels 74 and 76 formed by the wall corrugations and these channels are said to permit passage of the fluid(s) away from the heat exchange zone at low velocity without disruption of the jets. Both the heat exchange wall and the jet producing wall may be corrugated (Figs. 2 and 5). In such case the corrugations of the respective walls may be disposed (as in Fig. 2) to produce a spinning motion of the fluid in the said relatively large channels.

Abstract: 1305021 Radar TELECOMMUNICATIONS RADIOELECTRIQUES ET TELEPHONIQUES 8 Sept 1960 [8 Sept 1959] 31042/60 Heading H4D A radar triggering arrangement in which the beat signal between a frequency modulated emitted wave and a wave reflected from a target is used to produce a triggering signal when the target lies within the polar diagrams of the transmitting and receiving aerials, these being cones with a small common volume, comprises a transmitter adapted to produce a frequency modulated output having a wobbulation of such amplitude and frequency that mechanical resonances, and hence undesired microphony effects, are neglible, an amplifier through which the beat signal is passed and having a slope substantially corresponding to the increase of the slope of the curve of the energy reflected by an obstacle as a function of the distance of the obstacle, a counter of the number of cycles of amplitude modulation of the output of the amplifier, means for periodically resetting the counter to zero, and means for producing a triggering signal when the number of cycles counted equals a predetermined number. In Fig. 3 the transmitter 1 is a reflex klystron the reflector of which is modulated by a wobbulated sinusoidal oscillator 4. Signals from the receiver aerials are added to the transmitted signals and passed through filters 7, 71; detectors 8, 81; and amplifiers 9, 9<SP>1</SP> to a mixer 10. The difference output from mixer 10 is passed through a filter 12, which removes any amplitude modulation caused by amplitude modulation of the klystron, to a high-pass mean-frequency amplifier 13 the response curve of which has a slope of 12 db. per octave. It is explained in the Specification that if a target is present in the volume to which the apparatus is sensitive, the output of amplifier 13 will contain an amplitude modulation of twice the wobbulation frequency; this modulation is detected by detector 14 and amplified by a low frequency amplifier 15. Unit 16 is a level comparator which produces a pulse of constant width and amplitude in response to each positive peak input of sufficient amplitude, and a pulse counter 17 counter 17 counts the output of unit 16. Unit 18 is an integrator unit periodically reset to zero by unit 19, and when unit 18 counts up to a number of pulses which is fixed in advance a signal is sent to stage 20 to produce a triggering signal. When the mean reflector potential of klystron 1 is properly adjusted there is substantially no amplitude modulation at wobbulation frequency; if the mean reflector potential drifts away from the optimum the phase of the amplitude modulation produced indicates the sign of the deviation, and this phase is measured by comparing in unit 11 a sum output from unit 10 with an output from oscillator 4; the output of unit 11 is applied through unit 3 to control the mean reflector potential of the klystron 1.
