Title: Improvements in or relating to vending or dispensing machines
Inventor: BOURACIER CYRIL EUGENE
IPC: G07F11/36
Filed: 1962-08-21
Abstract: 1,061,923. Coin-freed apparatus. ICEMATIC Ltd. Aug. 21, 1963 [Aug. 21, 1962], No. 32137/62. Heading G4V. The dispensing door of a vending machine in which goods stored in compartments of a helix which rotates under gravity and descends on a helical path to present the compartments one by one to the dispensing door, has two projections 29, 30, projection 29 holding the helix in position when the door is shut and projection 30 holding the helix in position when the door is open. The door pivots about a horizontal axis 2 (Fig. 7) and has a flap 6 projecting within the machine. A shouldered stud 7, 8 on the flap 6 engages a socket 9 with a locking plate 10 when the door is closed. A coin falls to a shoot 18 (Figs. 1 and 2) and rests on pins 20, 21 where it provides an abutment for the probe 27 on the swinging arm 26 of a release knob or handle 25. Pushed by the probe the coin displaces bracket 13 on locking plate 10 to release the stud 7 and 8 and open the door. A ratchet-and-pawl, of which only pawl 32 can be seen in Figs. 1 and 3, ensures that the door can only be moved between the fully open and fully closed positions without intermediate change of direction. At one position of the door the projections 29 and 30 are ineffective to stop the helix descending and to confine the helix to a rotation equal to one compartment a spring-biased ratchet lever (Fig. 9, not shown) takes over the function of projection 29 until the door is closed and the projection is with certainty effective. The ratchet lever allows the helix to be wound upwards when the compartments are loaded with fresh goods. When the last compartment has been emptied the helix deflects a bell-crank lever 49, 50, 51 which by means of cable 52 deflects the clearing plate of the coin mechanism to ensure that all further coins are returned (Fig. 10, not shown). The clearing plate may be similarly deflected by the door until the door is properly closed.

Title: Improvements in reciprocating piston pumps for concrete and drier plastic materials
Inventor: WEISNER SVEN ERIK
IPC: F04B15/02
Filed: 1955-11-14
Abstract: 795,558. Reciprocating pumps. WEISNER, B. Nov. 14, 1955, No. 32424/55. Class 102(1). A concrete pump comprises parallel cylinders 43, 55, Fig. 4, in which are reciprocated out-ofphase pistons 45, 51 and which are connected at adjacent ends to a valve chamber which has a hopper inlet 63, Fig. 5, a discharge outlet 39 and a ported body 40 which is oscillated in unison with the pistons 45, 51 so that during the return stroke of piston 51 concrete is drawn from the hopper 63 through a valve body sector 49 into the cylinder 55 from which the piston 45 on its forward stroke forces concrete through a valve body passage 41 into the discharge outlet 39. The pistons are reciprocated by a driven pinion 46 engaging racks 47, 56 and the valve body 40 is rocked by a rack 42 engaged by pinions 58, 59 ; the latter being loose on the shaft 64 of pinion 46 and rocked thereon by abutment of a cam on shaft 64 against a cam of the shaft 62 of pinion 59. In a modification the valve body 17, Fig. 1, is rocked about a vertical axis by means of a link 6 connected by a rod 7 to the piston of a hydraulic cylinder 27 and has two through passages 3, 18 one of which connects the cylinder being discharged to an outlet 16 whilst the other is closed by the valve casing. Concrete is drawn from the hopper through one or other of spaces 10, 10<SP>1</SP> into the cylinder being charged. The out-of-phase pistons 19, 21 are mechanically connected to hydraulic cylinders 24, 23 in a circuit comprising a motor driven pump 26, a reservoir 37 and a distributing valve 30 reversal of which is effected by cams 28, 29 on the rod 7. Reversal of the distributing valve 33 for the valve actuating cylinder 27 is effected by abutment of cams 31, 32 against rollers 38, 39 carried by opposite ends of a valve rod 33<SP>1</SP>.

Title: Improvements in starting apparatus for electric motors
IPC: H02P1/20
Filed: 1923-12-29
Abstract: 230,575. Gowan, S., and Metropolitan- Vickers Electrical Co., Ltd. Dec. 29, 1923. Master control systems.-Sections of a starting resistance 4 of a series motor 1 are successively shorted by contactors 66, 67, 68 operated by coils 69, 70, 71 sensitive to a rise of voltage across the terminals of the motor, means being provided to prevent the failure of the successive action should the voltage across the supply mains 5. 6 fall below the normal. Under normal conditions, closure of a switch 60 causes the energization of a coil 61 to close a contactor 62 thereby starting the motor 1. When the voltage across the motor terminals rises sufficiently the coil 69 closes the contactor 66 and also a switch 72. which connects the coil 70 across the terminals so that is closes the contactor 67 and also a switch 75 upon a further rise of voltage. The coil 71 eventually closes the contactor 68. If the voltage across the mains 5. 6 is below its normal value, the voltage across the terminals of the motor may not reach a value sufficient to cause the closure of the contactor 66 or the succeeding ones 67, 68. In such an event a switch 81 operates upon sufficient diminution of the motor current to short a resistance 78 in series with the coils 69, 70, 71, thereby increasing the effective voltage across them so that the contactors act in a normal manner. The switch 81 acts quicker than the contactors 66, 67, 68 thereby preventing rapid cutting out of the resistance. In a modification the switch 60 is replaced by a drum controller giving both forward and reverse drives and also a starting position in which the motor runs continuously with full series resistance. In a further modification series resist. ances are substituted for the switches 72, 75.

Title: Electronic correction circuit in a timepiece
IPC: G04G5/02
Filed: 1972-07-12
Abstract: 1399024 Electronic timepieces SOC SUISSE POUR L'INDUSTRIE HORLOGERE MANAGEMENT SERVICES SA 22 June 1973 [12 July 1972] 32577/72 Heading G3T Relates to modification of the seconds display setting and correcting arrangement in an electronic timepiece incorporating a frequency divider chain operating a time display, particularly via a stepping motor, as disclosed and claimed in Specification 1385890. In the modification a single control push button switch is used to add seconds to or block seconds from the time display. The timepiece Fig. 1, has a main divider chain, only stages 9 to 18 being shown. Stages 17 and 18 are, in normal operation, set and reset alternately each second to control complementary transistor pairs which pass current alternately in opposite directions through a motor M. A manually operable setting switch P is followed by an integrator I to suppress effects of any irregularities  in switch contact. A predetermined delay T D  is set by a second sequence of dividers 20-23, and is initiated by the closure of switch P 1 . For each closure of switch P a second is added, i.e. time display is advanced by 1 sec. If the switch is maintained closed for longer than period TD, firstly 1 sec. is added during the period TD and then the "seconds" are suppressed or blocked. Normally the stages 20-23 are disabled when P is open, a transistor T 1  being saturated. When P is closed an output from an inverter N blocks T 1  and stages 20-23 count signals received from stage 10. During this time the leading edge of signal Q from stage 12 will switch a flip-flop 19 which in turn switches a toggle 16 thus adding 1 sec to display. If P is released before the end of period T D  i.e. before a flip-flop 24 is caused to change state, then 20-23 will be reset to zero and the main divider stages will be unaffected. If P is maintained closed for longer than T D , a transistor T 2  will saturate and remain so until P is released. For so long as T 2  is saturated, stage 11  will be clamped and this suspends the action of stages 12 onwards and thus suppresses current pulses to the motor. Alternatively, T 2  may be omitted and an AND gate inserted between stages 10 and 11, and controlled by stage 24. To set the phase exactly, a switch Sw is provided (e.g. operable by a crown of the timepiece) and together with a resistor R and transistor T 3  is used to clamp stages 12 to 16. When S W  is released the next motor drive pulse will follow 1 sec later. The toggle 16 effectively remembers the direction of the last current pulse to the motor.

Title: An improved process for the manufacture of fertilisers
IPC: C05B1/02
Filed: 1948-12-16
Abstract: In attacking natural phosphates with sulphuric and nitric acids and submitting the product to the action of ammonia or ammonium carbonate or bicarbonate, the whole of the phosphate ore is attacked by the whole of the sulphuric acid in absence of the nitric acid.  The reaction with sulphuric acid may be effected at about 100 DEG  C. either by using the hot acid leaving the lead chambers of a sulphuric acid plant or by using a mixer which is thermally insulated or has a heating jacket.  In the example, Morocco phosphate is treated with sulphuric acid and solubilization completed by delivering the product into a mixer at the same time as nitric acid.  The resulting mixture is then treated with gaseous ammonia.  Specification 642,177, [Group I], is referred to.  The Specification as open to inspection under Sect. 91 comprises also neutralizing excess of sulphuric acid and/or nitric acid with additional ammonia or another base.  This subject-matter does not appear in the Specification as accepted.ALSO:In making fertilizers composed principally of dicalcium phosphate and ammonium nitrate by attacking natural phosphates with sulphuric and nitric acids and submitting the product to the action of ammonia or ammonium carbonate or bicarbonate, the whole of the phosphate ore is attacked by the whole of the sulphuric acid in the absence of the nitric acid.

Abstract: 968,019. Cold separation of gas mixtures. A. HARMENS. Aug. 19, 1963, No. 32706/63 Heading F4P. Product nitrogen-lean gas is obtained from a nitrogen-rich feed gas mixture, e.g. natural hydrocarbon gas by liquefying the latter in a pass 17 of the reboiler 18 of a separating column 27 to which the liquid is fed through a duct 20, 26, withdrawing nitrogen - lean liquid from the base of column 27 through ducts 28, 30, cooling it in the warm side 21 of an aftercooler 22, reducing its pressure at a valve 32, vaporizing the so-cooled and expanded liquid in a heat exchanger 35 serving to condense nitrogen rich top gas of column 27 and withdrawing the nitrogen-lean gas through a duct 37 and discharging it as product through a duct 40. A portion of the condensed top gas is returned through a duct 44 as reflux whilst the remainder is expanded at a valve 45 into a separator 47 from which nitrogen gas is withdrawn through ducts 53, 54 and from which liquid nitrogen is expanded to ambient pressure at a valve 49 and passed to a storage tank 51. The after-cooler 22 also serves to cool the liquefied feed gas prior to its expansion at a valve 25 and entry into the column 27 and the after-cooler is cooled by an external refrigerant, e.g. liquefied natural gas admitted through at duct 55 and expansion valve 56. The resulting refrigerant vapour is added to product nitrogenlean gas in duct 37 whilst the residual liquid refrigerant is forced by a pump 59 into the product duct 40 after having cooled the feed gas mixture in an exchanger 12.
