Title: Article dispensing apparatus
IPC: G07D1/04
Filed: 1973-10-20
Abstract: 1420660 Dispensing machines E PETERSEN 20 Oct 1973 48975/73 Heading G4V An article dispensing machine, particularly a coin-freed change dispenser, comprises a column 21 for holding a stack of articles and a reciprocable ejector member 16 beneath the stack, the member, at the end of its ejection stroke dropping below the line of the ejection stroke and at the end of the return stroke being biased back into the line of the ejection stroke. In the embodiment described a coin or coins 12 inserted in a shoot 1 and held against upward movement by a pawl 10 act on clockwise rotation of a shaft 13 by the operator to tilt a pawl 2 carried by arm 3 fixed to the shaft (Fig. 2, not shown) and thus allow full rotation of the shaft to a first end position. A further arm 14 is fixed at one end to shaft 13 and at the other end is pivotally connected to a number of ejector members 16 associated with respective columns 21. On movement of ejector member 16 to the left, pins 19 extending laterally therefrom engage the underside of a pair of flaps 18 in a gap between which the member 16 moves until at the end of this stroke the pins pass beyond flaps 18 and the member is urged upwardly by leaf spring 20 so that during the ejection stroke the pins 19 ride on the upper surface of flaps 18 and the ejector engages a coin or coins supported on a slotted flap 23. The pins 19 are eccentrically mounted on a shaft (31) (Figs. 3 and 4, not shown) so that their vertical position relative to the ejector member can be adjusted for different thicknesses of coin.

Title: Methods and machines for manufacturing articles from thermo plastics sheet material
IPC: B29C48/08
Filed: 1973-10-24
Abstract: 1443523 Extruding thermoplastics; sheet forming BELLAPLAST GmbH 24 Oct 1973 [25 Oct 1972 19 Dec 1972 4 June 1973 6 Sept 1973] 49606/73 Heading B5A A method of manufacturing synthetic plastics articles includes the steps of forming a web I, e.g. by means of an extruder 2, and cooling at a opposite surface of the web at station 3 to provide outer layers that are sufficiently deformable to permit shaping at station 6, and a hotter inner layer which remains capable of flowing. In Fig. 6 the web is cooled by rollers 31, 33. Roller 31 can be adjusted along a sector 32 in order to vary the contact time between the web and rollers, and consequently the temperature of the outer layers. Cooling medium can be circulated through the rollers, and the temperature of such medium can be varied. In Fig. 1, a single web I. passes from the station 3 to a movement conversion device 4, where a roller (41), Fig. 8, not shown, moves vertically to compensate for the continuous movement of the web from the extruder and the intermittent movement of the web through a forming station 6 and stamping station 7, before the waste material passes to a recycling device 81. In Fig. 2, not shown, a composite web is formed by two extruders (11), (12) which can deliver different materials, e.g. polystyrene and a butadiene rubber modified polystyrene. In Fig. 3, not shown, three extruders (11) (12), (13) are used.

In an analogue-to-digital converter of the type in which the voltage produced by a transducer (e.g. thermocouple) or the resistance of a variable-resistance transducer is digitally balanced, by a voltage or resistance respectively, by sequentially switching appropriately weighted resistors into circuit and selectively removing those that cause overbalance, additional resistors are switched into circuit at appropriate steps in the sequence whereby the non-linear characteristic of the transducer is approximated to by a number of straight line segments. In the voltage-digitizing embodiment (Fig. 4, not shown), the unknown voltage (t 18 , t 19 ) is backed-off (t 17 ) by a known voltage produced by sequentially switching parallel - connected binary - coded - decimal weighted resistors (R 800 , R 400 , R 200  &c.) into circuit and selectively removing any that cause overbalance and at appropriate steps in the sequence additional resistors are connected to modify the unknown voltage so as to achieve a three-line approximation (Fig. 3, not shown) to the desired characteristic. In the resistancedigitizing embodiment (Fig. 1, not shown), the unknown resistance is arranged in a Wheatstone bridge in one arm of which series-connected are sequentially unshunted and selectively held as before.

Each holder is apertured to engage a carrier. As shown in Fig. 4, a main body 1 has parallel legs 2, 3 resiliently connected thereto. A bridge 4 shown in the relaxed position, connects the legs 2, 3. Lugs 5, 6, are arranged to grip the side edges of a rectangular slide while the end edge engages lugs 9, 10. To insert a slide the bridge 4 is bowed away from the body 1 to an over centre position wherein the legs are splayed. On introducing a slide the slide end engages the bridge to "flip" it to the relaxed position whereupon the legs grip the slide edges. A carrier, e.g. a rod, may be inserted in a hole concentric with the peg 12 or in slot 14. In the embodiment of Fig. 5 the legs are rigidly attached to the body by fillets 23 which do not extend the whole thickness of the body. Resilient lugs 24 engage the slide edges to urge the rear of the slide against the fillets. Notches 29, 30 are provided for engagement in automatic slide handling systems. The ends of the legs 21, 22 may be thinned to allow easy engagement when a plurality of holders are stacked.

Hydrazine hydrate is obtained from an aqueous solution of a hydrazine salt by contacting the solution with a macroreticular anion or cation exchange resin. If an anion exchange resin is used the hydrazine hydrate is recovered by separating the solution from the resin; if a cation exchange resin is used, the resin is separated from the acid liberated in the process, and is then treated with an aqueous base (preferably a 4-20% by wt. solution of ammonia) to liberate the hydrazine. The ion exchange resin is preferably polystyrene or a styrene-divinylbenzene copolymer substituted for cation exchange with sulphonic, carboxylic, phosphoric or phosphinic acid groups and for an anion exchange with an aromatic or aliphatic amine or a quaternary ammonium compound. The resin is preferably used as a stationary bed in one or more columns in series, the hydrazine salt solution (which preferably contains 2-30% by weight of the salt) being passed at a temperature between 15‹ C. and the boiling point of the solution or the maximum permissible temperature for the resin.

Abstract: 1,192,957. Radar control of missiles. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 14 Nov., 1967 [18 Nov., 1966], No. 51846/67. Heading H4D. The Specification describes a missile control system of the type comprising a fixed or moving control station B, Fig. 1, including monopulse radar means for detecting and determining the position of the target and for interrogating and identifying each missile, and remote control means for transmitting homing instructions to each missile on the basis of the radar data, and on each missile A a responder for responding to the radar interrogation and a receiver for the homing instructions. The invention lies in that only one wave energy source is required at A and B. So that each missile may be-interrogated at a different frequency, the wave energy source 102 at the control station comprises an oscillator for each missile (e.g. two in the present case of two missiles) at different frequencies. A particular oscillator output at frequency F, is thus selected by switch 10, is frequency multiplied to KF1 at 9 and the resultant wave fed to mixer 7 as the radar receiver local oscillation and to radar transmitter 19 such that a radar pulse E1, Fig. 2, is transmitted to the target. The echo Eh therefrom is analysed in receiver 13 and computer 20 such that the latter produces homing instructions to the missiles. A switch 11 now applies the oscillator output to interrogating transmitter 12, such that an interrogating coded pulse group ATI at frequency F1 is transmitted to the missiles. The wave energy source 1 in the missile A operates of frequency F 3  and feeds mixer 6 as the local oscillation and frequency multiplier 2 to provide the response carrier at frequency KF3. The interrogation signal is received and heterodyned at 6 and the pulse group at intermediate frequency (F1-F3) is fed to decoder 4. If the code is correct, decoder feeds a trigger pulse to modulator 3 and a response pulse group F1 at frequency KF3 is transmitted to the control station. The missile having been identified, the appropriate homing instructions 01 are transmitted by 12 at frequency F and output 41 of the decoder pass corresponding signals to the missiles flight control systems. The cycle is repeated in period T2 for the other missile using the oscillator output at frequency F2.
