Title: Improvements in or relating to coin freed turn stiles or inlet cages
IPC: G07F17/14
Filed: 1930-08-28
Abstract: 361,011. Coin-freed turnstiles. DELUCE, S. A. N., 323, Bolton Road, Pendleton, Manchester. Aug. 28, 1930, Nos. 25670/30 and 5868/31. [Class 27.] In a coin-freed turnstile, which allows free exit without control by an attendant, the vertical spindle 1, Fig. 4, carrying the usual radiating arms has secured to it at the bottom a ratchet wheel 15, the teeth 16 of which engage pawls 17 pivotally mounted on a locking plate 7 and held in engagement with the teeth 16 by springs 19. The plate 7 is loosely mounted on the spindle 1 and has four notches 8 engaged by a bolt 9 normally to prevent rotation of the turnstile in the inlet direction. Rotation of the plate 7 in the reverse direction is prevented by pawls 14 pivoted to the casing and engaging ratchet teeth 13 on the plate. After prepayment, the bolt 9 is withdrawn against the action of a spring 10 and retained by a shoulder 36 of a pivoted spring-controlled detent 34 engaging a projection 9a on the bolt. When the spindle 1 has made a quarterturn, one of four tappets 18, formed as extensions of the pawls 17, engages an arm 38 of the detent 34 to release the bolt which then engages the next notch 8. During inlet, the wheel 15 drives the plate 7 through the pawls 17. During exit, the plate 7 is held by the pawls 14 and the pawls 17 slip over the teeth of the wheel 15. The spindle 1 is positioned after' each quarter-turn by spring- pressed arms 43, 44, Fig. 9, engaging a squared portion at the top of the spindle. A hand-operated control in the exit direction may be provided to prevent the spindle 1 from being manipulated to a mid-way position between the arms 43, 44. This comprises a locking disc 47 with four teeth 48 engaged in turn by a bolt 49 operable through linkage by a handle 56. This bolt is retained by a detent which is released by tappets 61 acting similarly to the detent and tappets 34, 18. The releasing arm 60 of the detent is jointed to allow rotation of the spindle in the inlet direction. Coin action, mechanical connection.-A coin is inserted through a slot 33, Fig. 7, and falls to a position between plungers 27, 24, Fig. 6, controlled by springs 29, 28. The plunger 27 is moved by a crank arm 31 operated by a handle 32, and, through the coin 26, moves the plunger 24 which, through a crank 21a, rotates a vertical spindle 22. The spindle 22 at its lower end has a crank 21, Fig. 4, connected to an extension of the bolt 9 to withdraw this from a notch in the plate 7. Coin-discharging mechanism.-An incline 39 on the plate-7 presses the bolt 9 further back thereby releasing the plunger 24 from the coin which drops through a slot 40. Clearing devices.-A bent coin is removed from the slot 33 by a tool inserted through a hole 42 in the front wall 41 of the slot.

Abstract: 997,809. Towelling dispensers. NEUCO APPARATEBAU A.G. June 22, 1964 [June 21, 1963; Jan. 14, 1964], No. 25674/64. Heading A4G. An automatic hand towel machine includes a measuring roller 1 over which the towel strip is drawn from a supply roll 2, a pressure roller 3, a drive roller 5 coupled by a chain (not shown) to roller 1 and driving a roll 6 to wind on the used towel, a clockwork spring in a housing 11 rotatably mounted on a spindle 9 the spring end being secured to the spindle and housing a spring tensioning device comprising a toothed wheel 13 on spindle 9, pivotable locking pawls 14, 15 and a lever 8 moved by an eccentric disc 7 on the shaft of the measuring roller 1 and pivotally mounted on spindle 9, a locking lever 17 pivotable about a pin 17a and a pivoted flap 18 resting on the hand towel to act as a detector of the passage of the end of the towel and release the locking means so that the spring can operate the drive roll and withdraw the end of the towel into the machine. As the towel end passes flap 18 projections on the latter can fall into slots in roller 3 so that a pin 20 on flap 18 moves a lever 21 which moves locking lever 17 to allow the spring to turn housing 11 and hence drive roller 5 through toothed wheels 13, 27 to wind the end of the towel on to roll 6. In a modification, Fig. 4, a tongue 41 carried by a spindle 40 rests on the towel and the spindle also carries a lever arm 42 having a permanent magnet 43 movably mounted on its end, this magnet being at a relatively large distance from an armature 39 on a lever 35 which holds a locking lever 33 in locking position so that when the towel has run over pressure roller 3 the tongue 41 falls into a slot in the roller moving magnet 43 closer to the armature 39 to attract it with greater force and thus move the levers to release the clockwork spring.

Title: Process for the production of metallic niobium or tantalum by the electrolysis of melts
IPC: C25C3/34
Filed: 1957-08-14
Abstract: 873,844. Electrolytic production of niobium and tantalum. CIBA Ltd. Aug. 14, 1957 [Aug. 14, 1956; July 9, 1957], No. 25690/57. Class 41. Niobium or tantalum is deposited by electrolysis of a double fluoride of niobium or tantalum, preferably with sodium or potassium, in an oxygen-free alkali metal or alkaline earth metal halide melt at a temperature of 650‹ to 950‹ C. at an anode current density which is below the critical value at which anode effect occurs. Either the anode current density is chosen at a value below the critical value at the final concentration of free alkali metal fluoride in the melt attained when all the niobium or tantalum has been deposited or it is reduced as the metal is deposited so as to maintain it below the critical value throughout the electrolysis, the critical value varying inversely with the concentration of free alkali metal fluoride. Typically electrolysis is effected at 750‹ to 900‹ C. using a sodium chloridepotassium chloride melt to which the double fluoride of potassium and pentavelent niobium or tantalum is added, the graphite crucible serving as anode with a central nickel cathode. A nitrogen or inert gas atmosphere over the bath is employed. In the case of niobium a diaphragm is arranged between anode and cathode to restrict the passage of lower valency niobium compounds soluble in the melt to the anode. Empirical formulae for calculating the critical value of the anode current density are given in the Specification.

Title: Improvements in the catalytic production of acetaldehyde
Filed: 1948-10-05
Abstract: Acetaldehyde is produced by causing acetylene and water vapour to react in a reaction chamber at elevated temperature in the presence of a phosphate catalyst, phosphoric acid, or a phosphoric compound capable of emitting phosphoric acid under the conditions of the reaction, being continuously or intermittently supplied to the reaction chamber.  The phosphoric acid or compound capable of emitting phosphoric acid may be injected into the gases before they enter the reaction chamber or may be sprayed directly on to the catalyst in the reaction chamber.  The gases carrying the phosphoric acid or phosphoric acid-producing compound may be conveyed to the reaction chamber through another chamber having such a temperature as to cause the precipitation of excess phosphoric acid.  Esters of phosphoric acid may be used as compounds capable of emitting phosphoric acid.  In the example a mixture of acetylene and water vapour in the ratio of 1 to 4 and having a temperature slightly below 300 DEG  C. is introduced into a container coated inside with graphite and active carbon.  The carbon is impregnated with phosphoric acid and concentrated phosphoric acid is added continuously or intermittently.  The gases are passed through the container into a reaction tower filled with a catalyst consisting of active carbon impregnated with zinc phosphate.  The temperature in the reaction tower is suitably about 250 DEG  C.

Abstract: 1,169,738. Automatic temperature control systems. DIAMOND H CONTROLS Ltd. May 24, 1967 [June 10, 1966], No.25939/66. Heading G3R. In an automatic temperature control system utilizing patches of complete half cycles, low energy pulses substantially co-incident with supply voltage zero points and having a large spacemark ratio are passed through a resistance sensor. A bridge circuit having a thermistor or platinum wire temperature sensor modifies the amplitude of rectangular pulses initialled at the commencement of each half wave of supply frequency, which are added to a series of linearly ascending amplitude pulses, say 50 in number, to find one or a pair of thyristors SCR1, 2, which pulses may be alternatively added in separate transformer windings Fig. 7A (not shown). To embrace 3 term control, the bridge output may be applied to a field effect transistor controlling an amplifier before adding the ascending pulses, or an F.E.T. differential amplifier which may set the level of origin of the ascending pulses. Each pulse may be divided into a series of H.F. uni-directional pulses contained within an envelope of the same outline as a pulse, and/or be phase shifted to cater for capacitive or inductive loads. An amplifier may replace the transformer T3. Relay circuits may be substituted for the thyristors.

Title: Improvements in or relating to liquid electric power switches and the like
IPC: H01H3/30
Filed: 1932-09-19
Abstract: 392,051. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Sept. 19, 1932, No. 26036. Convention date, Nov. 28, 1931. [Class 38 (v).] The movable pin contact of a switch of the "expansion" type is withdrawn from the fixed contact at a speed in excess of three metres per second whereby a maximum vapour pressure, ready for the expansion effect, is produced with a minimum of arc energy and re-establishment of the arc is avoided by the rapidly-produced gap so that the circuit may be interrupted at the zero of the cycle during the first half wave. The rapid movement is produced by a powerful spring 20 which has a flexible connection 31 with the sector 30 pivoted at 29 and carrying a crank 23. The sector is held in the position shown with the spring stressed by a catch and the sector is so shaped that as it rotates the mechanical advantage of the spring in producing the rotation is reduced. The crank is pivoted to the middle of a link 21, one end of which is pivoted to a block mounted on the switch pin 14 and constrained to move between the rails 18. The pin engages the fixed contact 13 in the switching chamber and is surrounded by spring-pressed rings which conserve the vapour pressure developed until it is adequate to extinguish the arc by sudden expansion. In the position shown, the linkage system is near its dead-centre position so that the spring has a double mechanical advantage (that due to the shaped sector and that due to the position of the linkage) in effecting initial movement of the switching pin. Thereafter, the speed of the pin is rapidly increased and at an intermediate position the free end of the link 21 engages jaws 34 by which it is momentarily retained while the crank stll further raises the pin and, the free end escaping, drives the pin into the neighbourhood of the second dead-centre position.
