Filed: 1974-07-08
Abstract: 1458288 Bottle washing apparatus SEITZWERKE GmbH 8 July 1974 [1 Sept 1973] 30213/74 Heading B8T The washing stations of a bottle washing apparatus each comprise a reservoir divided into compartments 10<SP>1</SP>, 11<SP>1</SP>, 12<SP>1</SP> separated by walls 21, 22 upon which are mounted deflector plates 23, the plates serving to deflect a portion of the cleaning liquid incident upon the bottles rearwardly relative to the direction of motion of said bottles so that it falls into the earlier and more contaminated compartment. Cleaning liquid enters compartment 12<SP>1</SP> through an inlet 19 and is sprayed on to the moving bottles via nozzles 15 vertically above the compartment; the liquid passes inside the bottles and is deflected on to the outer surfaces by a baffle 16, after which it descends into the reservoir. A portion of the liquid is deflected by plate 23 pivoted on wall 22 into compartment 11<SP>1</SP>, the quantity of liquid deflected being dependent upon the liquid level in compartment 12<SP>1</SP> this being determined by a float 27 and lever mechanisms 28 which varies the angle which plate 23 makes with the vertical. Similarly, liquid is transferred from compartment 11<SP>1</SP> to compartment 10<SP>1</SP>. In this manner a continuous transfer of liquid occurs between the compartments in each reservoir, finally leaving via an outlet 20.

Title: Fire-responsive control device utilizing thyristors
IPC: H03K17/24
Filed: 1974-07-08
Abstract: 1473401 Thyristor switching circuits HOCHIKICORP 8 July 1974 [26 July 1973] 30221/74 Heading H3T [Also in Division G4] Fire responsive apparatus includes a thyristor controlled by a fire responsive device and controlling emergency apparatus, an oscillator for periodically quenching the thyristor so that it goes off when the fire responsive control signal terminates, and delay means maintaining the emergency apparatus operated during the periodic quenching. In the prior circuit of Fig. 1, a thyristor is connected across a D.C. supply in series with an oscillator P and a load Re, for example a relay. When the thyristor is rendered conducting the oscillator causes a relay F intermittently to short circuit the thyristor and switch it off so that if the control signal at the gate is discontinued the thyristor does not reconduct. Fig. 2 shows a circuit according to the invention in which, while the thyristor has a trigger voltage at its gate, contact I of a relay L energizes the load Re and an oscillator F periodically changes over the contact f1 and f2 to periodically extinguish the thyristor, the capacitor C2 maintaining the load energized. In Fig. 3, while the thyristor has a control signal at its gate a transistor Q4 conducts causing Q2 and Q1 to conduct to energize the load Re. Conduction of Q4 also energizes an oscillator comprising charging resistance R7 capacitor C3 and a unijunction transistor PUT the oscillator serving to periodically render transistor Q3 non- conducting so as to cause periodical extinction of the thyristor. Capacitor C4 prevents intermittent energization of the load. In Fig. 4 detection of flame or smoke fires the thyristor to render transistor Q4 conducting and thus cause transistors Q2, Q1 to actuate a relay Re controlling a fire door or a smoke exhaust. Conduction of Q4 also energizes an oscillator comprising R7, C3 and the unijunction transistor PUT and this causes a transistor Q5 to effect the periodical extinction of the thyristor.

Title: Improvements in the manufacture and production of hydrogen and phosphoric acid
IPC: C01B3/06
Filed: 1928-10-20
Abstract: 324,122. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 20, 1928. Hydrogen and phosphoric acid are obtained by reacting phosphorus with water or water vapour under pressure and at an elevated temperature and then subjecting the gaseous and liquid reaction products separately or b o t h together to another pressure treatment in a second stage, if desired with the addition of water or water vapour. In one form, Fig. 1, phosphorus and water enter at A, A<1> respectively a pressure-tight vessel I. The acid formed by the reaction flows through pipe H to a pressuretight vessel III to which water or water vapour may be added at J. The hydrogen evolved leaves at L and the acid is drawn off at K. A mixture of steam, hydrogen and phosphine leaves vessel I at B and is treated in a vessel II with steam entering at F. The hydrogen leaves at D and the weak phosphoric acid is drawn off at E and can be introduced into vessel I or II. In another form, the gaseous and liquid reaction products are both introduced into one vessel, the gas flowing in counter-current to the acid. Steam or water may be added to the gas on its way to the vessel. The hydrogen leaving the vessel may be passed, if desired with the addition of water or steam, over a catalyst, which may be a heavy metal of the first, sixth and eighth groups of the periodic table or compounds or mixtures thereof, in a further vessel to oxidize the phosphine present to phosphoric acid. The reaction between the phosphorus and water may be effected at 300-400‹C., and at a pressure up to about 500 atmospheres and the further treatment of the gaseous and liquid products may be effected in two separate vessels at temperatures between 300-400 ‹ C. , and at pressures up to 500 atmospheres. Where a single vessel is used for the after treatment, the pressure may be about 400 atmospheres. Reference has been directed by the Comptroller to Specification 308,599.

Title: Improvements in and relating to the control of electric motors driving winding engines, hoists and the like
Inventor: PETCH THOMAS HAYES
IPC: H02P7/34
Filed: 1950-12-19
Abstract: 710,696. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 16, 1951 [Dec. 19, 1950], No. 30897/50. Addition to 577,183 and 624,684. Class 38(3) In a modification of the Ward-Leonard system for the control of winding engine and similar drives which is described in Specification 624,684 the rectifiers 11a, 11b, are connected at adjustable positions x and y to a potentiometer 29 which is energized from an independent source of directcurrent and has its mid-point connected to the field winding 21. The other terminals of the rectifiers have a common connection w. The rectifiers 11a, 11b, are thus subjected to potentials derived from the constant source connected to potentiometer 29 and from the variable source represented by the energy storage device 13 and resistor 22. If the potential at w is greater than that of y, such as may occur with a greater rate of acceleration than is desirable, the field winding 21 is energized to check the rate of increase of the output voltage of the amplidyne 5. If the potential at x is greater than that at w the winding 21 is energized to prevent too rapid deceleration. Similar operation is obtained when the potentiometer 7 is adjusted for reversal of the motor 1. The elements 13 and 22 may be connected across the generator 3 or across the terminals of a tachometer generator driven by the motor 1.

Title: Method and apparatus for generating facsimile signals
IPC: H04N1/36
Filed: 1952-12-05
Abstract: 729,783. Copying-telegraphy. CREED & CO., Ltd. Dec. 5, 1952 [Dec. 13, 1951], No. 30918/52. Class 40 (3). In a method of generating facsimile signals by the scanning of a blank upon which the matter to be transmitted is delineated, there is periodically produced during such scanning a phasing signal having a given duration and employed to suppress any facsimile signals for a period equal to said duration. The matter to be transmitted is on a sheet 12 mounted on the inside of a transparent drum 10 rotated by a motor 11 and is scanned by a light beam 13 and a photo-electric cell 15 in combination with a chopper disc 16, the assembly being traversed along the drum. A light-source 19 projects a beam 18 on to a photo-cell 20 which produces negative impulses when the beam passes through a transparent portion of the drum formed by the gap between the' edges of the sheet 12. When the tongue 32 of a switch 33 is in its floating position, the positive and negative half-cycles of the phasing impulses from the oscillator 34 are respectively blocked by the rectifiers 38, 39. When the phasing operation is to take place, the tongue 32 is moved against contact 40 and the negative pulses produced at the cathode of the valve 31 in response to the negative pulses provided by the cell 20 allow the rectifiers 38, 39 to conduct and to pass the phasing impulses from the oscillator 34 for a period corresponding to the rotational speed of the drum and the width of the gap 30 between the edges of the sheet 12. As the cathode of the valve 31 normally provides a positive bias to the rectifiers 38, 39, an adjustable positive potential is applied to a centre tap on the primary of the transformer 36 to allow a relatively small negative impulse at the cathode of the valve 31 to render the rectifiers 38, 39 conducting. For the transmission of the subject-matter, the tongue 32 is removed against contact 47 and rectifiers 45, 46 between the transformers 43, 44 are poled so that they are rendered conductive by positive signals from the positive signal amplifier 42. The negative impulses produced at the cathode of the valve 31 make the rectifiers 45, 46 non-conductive so that facsimile signals produced when the gap 30 is scanned are suppressed and not transmitted. A positive bias is applied from a potentiometer 48 to counteract the normal positive bias from the cathode of valve 31 and can be adjusted so that rectifiers 45, 46 do not conduct until the amplitude of the picture signals exceeds a predetermined value with the result that background marks are suppressed. In a modification, Fig. 3 (not shown), the sheet carrying the matter to be transmitted is mounted on the outside of the drum and the phasing output signal is obtained by reflection from the drum. The phasing control signal is obtained from the cathode or anode of the valve, corresponding to the valve 31, Fig. 2, according as to whether the reflectivity of the drum surface is respectively greater or less than that of the surface of the sheet carrying the matter to be transmitted.
