Abstract: 1,238,523. Coin-freed vending machines. VENDO CO. 2 July, 1968 [27 March, 1968], No. 31481/68. Headings G4V. [Also in Division A4] An article vending machine has stationary banks of columns 34, 36, 38 and a movable bank of columns 142, each column containing a stack of articles, e.g. packages of cigarettes of a particular brand. A carrier 28 is reciprocable on rollers 68 running in tracks 66, cogs 70 on the rearmost rollers engaging racks 72, and it carries an article ejecting assembly 30 for each stationary bank. An article, ejecting assembly 32 for the movable bank is mounted on the stationary bank 34. Each ejecting assembly 30 or 32 has a solenoid coil 92, armature (94) and an ejector 96 movable with the armature for each column. When the coil is energized, the ejector 96 is raised from its standby to its article ejecting position in which a horizontal upper leg (102, Fig. 3) thereof enters a slot in the base of the column so that relative movement between the ejector and the column will push the lowermost article rearwardly out of the column. The ejected article gravitates down a shoot 108 to a front delivery station 110. Each assembly 30 or 32 has an elongated pivoted latch bar 112 yieldably biased by springs 118 to the left in Fig. 2. Each ejector 96 can be latched in its ejecting position by a latch member 122 of bar 112 engaging therebeneath (see Fig. 5). Latch bar 112 is released when a projecting end thereof engages a spring 128 mounted on a fixed bracket 130 or on the movable bank 142. Each bank has an elongated cancel bar 132 that is tilted by an article being ejected to actuate a switch 138 to reset the coin controlled mechanism. The movable bank 142 is pivotally mounted on fixed brackets 144 and is coupled to the carrier 28 by arms 146 pivotally connected to the bank and carrier respectively through bolts 152 and pins 150. Arms 146 are also pivotally mounted on fixed brackets 156 so that when carrier 28 moves to the left, Fig. 2, bank 142 is swung to the dotted position, and vice versa. Upon deposit of coins and the operation of a selector button one solenoid coil 92 is energized, and a motor (76, Fig. 1) drives carrier 28 and bank 142 through one cycle by means of an eccentric 80, a pivoted arm 82 and a pivoted bar 84 connected to the carrier. Carrier 28 moves to the left and back, and bank 142 swings to the right and back, and the lowermost article is ejected from the column by the selected raised ejector. Bank 142 may extend for only a portion of the width of bank 34.

Abstract: 1,252,272. Plutonium compounds; nuclear fuel. COMITATO NAZIONALE PER L'ENERGIA NUCLEARE. 11 Oct., 1968 [13 Oct., 1967], No. 48435/68. Headings G6C and G6R. Dense particles of a plutonium compound are prepared by treating a plutonium salt solution with a liquid anion exchanger (i.e. a liquid capable of complexing with anions through a liquid/solid or liquid/liquid interface) to reduce the anion/Pu ratio, concentrating if necessary, and dispersing the resultant colloidal solution as droplets in an immiscible solvent containing a liquid anion exchanger to form gel particles which are calcined. Mixtures of a plutonium compound and a compound of another lanthanide or actinide metal or of beryllium or zirconium may be prepared by mixing the colloidal plutonium solution with a colloidal solution of the other metal. Powdered carbon may be added to form the carbides. Calcination may be in air, hydrogen, a mixture of hydrogen and argon, or in vacuum; calcination in nitrogen, hydrogen sulphide, or hydrogen phosphide of gels containing carbon produces the metal nitrides, sulphides, or phosphides. Examples describe the preparation of PuO 2 , UO 2 -PuO 2 , and thorium-plutonium carbide. For use as nuclear fuel, the particles may be coated and dispersed in graphite, or may be compacted by vibration. Specification 1,116,535 is referred to.

Abstract: 1,258,101. Adjustable backrests. C.M.W. LABORATORIES Ltd. March 24, 1969, No. 15271/69. Heading A4J. The inclination of a backrest (2), Fig. 4 (not shown) of a chair is controlled by a piston and cylinder 3 and 5, Fig. 1, of a hydraulic control circuit (4) which locks the backrest in a reclined position and which includes a valve 10 which controls the rate at which the backrest is lowered. The valve 10 comprises a ball 20 which is held on the valve seat by a rod 23 which is coarse screw threaded into the body of the valve and which on rotation moves away from the ball to allow movement of the ball from its seat and allow increased flow of fluid through the valve which results in a greater rate of lowering of the backrest. The valve is operated by a hand lever 28 which is attached to the valve via a cable arrangement. The backrest can be raised manually without using the pump 11, such manual lifting causes the piston to be drawn out of the cylinder 5 and fluid to be drawn into the cylinder via pipeline 6 and a oneway valve 12.

Abstract: 1,258,397. Hydrostatic transmission. NATIONAL RESEARCH DEVELOPMENT CORP. 20 March, 1969 [25 March, 1968], No. 14374/68. Headings F2C and F2D. [Also in Division F1] A hydrostatic transmission with positive displacement pump(s) 1 and motor(s) 26 in a closed loop-lines 21 and 22<SP>1</SP> has the pump displacement variable in discrete steps (e.g. by tilting a pump swashplate or selectively connecting different capacity pumps) to a maximum to increase the transmission ratio, which can be increased further by reducing simultaneously the pump displacement and by a greater proportion the motor displacement (e.g. by reducing the number of motors in the circuit or by cutting out one of two banks of radial cylinders of a ball piston motor (see Division F1). The transmission may be manually controlled by a lever 20 having hydraulic (Fig. 1) or mechanical (Fig. 7) connections to a servo tilting the pump swashplate. The lever 20 may also control a reversing valve 23. The pressure difference between lines 21 and 22 may be relieved by opening a valve 29 with a hat shaped piston normally closed by a spring supplemented by the higher pressure fed to a chamber 32 via check valves 44 and 47. The valve 29 opens when pressure in the chamber 32 is relieved by the opening of either a valve 48 under excess pressure, a valve 49 when the engine speed falls to idling, or a valve 50 opened by the lever 20 either when the transmission is in neutral or when changing pump and/or motor displacement.

Abstract: 1,264,573. Brake-lining wear indicators. BENDIX CORP. 13 April, 1970, No. 17516/70. Heading F2E. An electrically-conductive member electrically connected to an electrical warning device has a contact region located within the thickness of a brake friction lining at a position for which the contact region comes into frictional engagement with a friction surface engaging the lining when the lining thickness reaches a predetermined minimum value; in the simpler form of the invention (Figs. 5 and 6, not shown), the contact region is adapted to be cut and removed after a predetermined period of frictional engagement with the friction surface, thereby providing an open circuit condition which causes the warning device to be actuated (continuously). Preferably, a test switch is incorporated in both forms of the invention. As shown, a U-shaped conductor member 56, Fig. 3, includes a flat portion 62 constituting the contact region which, when the lining 22 has worn down to a thickness AA, makes contact with the brake drum 10 which is earthed. The U-shaped conductor forms part of probe means 30 (see also Fig. 2) from which wires 44, 46 extend for connection in the circuit of Fig. 2. Four probe means 30 are shown in series in Fig. 2. In normal working, ignition switch 42 and test switch 86, Fig. 2, are both closed, and with the circuit as shown, transistor 68 is non- conducting, so indicator (lamp) 36 is not energized. When any of the probes 30 (one for each wheel), makes contact with its drum (as mentioned above), the probe is earthed by the drum, and when this occurs the circuit conditions are changed so that transistor 68 conducts, and the lamp 36 lights. When the brake is released, and provided the flat contact region 62 is not yet worn away, the circuit is restored to its normal condition, and the lamp 36 is consequently extinguished. When sufficient further wear occurs for the region 62 to be worn away and removed by the action of the brake drum, the circuit between wires 44 and 46 is broken. This again renders transistor 68 conducting, but permanently, so lamp 36 is illuminated continuously. The test switch 86 is automatically opened momentarily, whenever the engine is switched on; such opening renders the transistor 68 conducting, so the lamp 36 is illuminated, thereby indicating that the apparatus is in working order.

Abstract: 1295161 Transistor gating and waveform generating circuits HAMMOND CORP 1 Jan 1970 [2 Jan 1969] 113/70 Heading H3T [Also in Division G5] A musical instrument keyer-synthesizer (30), Fig. 2 (not shown), has four inputs (31-34), an output (36), and a control input (35), and when a set of square waves whose fundamentals are related in the ratio 1: 2: 4: 8 are applied to the input, they are adjusted in amplitude so that whenever a voltage is present at the control input a stairstep approximation to a sawtooth wave (137), Fig. 3 (not shown), appears at the output (36) as the result of an addition process. The circuit may comprise MOSFET transistors (101, 104) with the gates all connected to input (35) and the drains to the output (36), the inputs being applied to the sources, the source-drain impedances being scaled so that the individual outputs combine to give the waveform (137), Fig. 3 (not shown). The MOSFETs may have a common substrate or together form an integrated circuit. The input signals may be combined using a four emitter transistor (130), Fig. 3 (not shown), the inputs being applied to the four emitters via scaling resistances (133-136), and the control input being applied to the base (131). The musical instrument comprises a square wave generator, connected to inputs 20A-20F of a keyer-synthesizer unit 12 where square waves of frequency ratios 1 : 2 : 4 : 8 : 16 : 32 are present, and which are each connected to one or more keyer-synthesizers 30A-30E which are conductive when a control signal, received from switches 82, 83 (which may be transistors) via response and decoy shaping networks 17, 19, is present. The approximate sawtooth waves produced, 130, are fed via outputs 76-80 to shaping switching and amplifying circuits, and thence to a loud-speaker 20. Several units 12 may be mounted on a single substrate, and the loading effect of the units 12 may be reduced by connecting the inputs 20A-20F to the units via the gates of MOSFET transistors whose sources are connected to a positive bias at (121), Fig. 4 (not shown), the drains being connected to the keyer-synthesizer inputs.
