Title: Fluid proportioning system
IPC: G05D11/00
Filed: 1971-04-19
Abstract: 1308123 Dispensing measured quantities of liquids D TANNER 19 April 1971 [24 Feb 1970] 21806/71 Heading B8N [Also in Division B1] Apparatus for simultaneously dispensing measured quantities of a plurality of liquids into a common outlet line comprises a plurality of cylinders 11-14 mounted on a base 30. Each cylinder includes an inlet 37, and an outlet 38 and contains a valve 40 rotatable about the axis of valve rod 41, and a piston 54 reciprocable between end positions defined by a spacer 52 and a shoulder of an adjustable stop member 46. A magnet 56 carried by the piston closes an upper switch and a lower switch when the piston is at its upper and lower positions respectively. The valves are movable simultaneously by means of a crank arrangement (Fig. 3) actuated by a pneumatic ram 86. The upper switches 57, 61, 63, 65 when all closed, actuate a solenoid 95, and the lower switches 58, 62, 64, 66 when all closed actuate a solenoid 96. The solenoids when actuated each effect movement of a valve 97 so as to switch supply of compressed air from one end of the ram cylinder to the other. In operation with the valves 40 each in the position illustrated in Fig. 2 liquids pass via inlets 37 and peripheral notches (43) (Fig. 5, not shown) into the cylinders below the pistons. The pistons are moved upwardly and liquids above the pistons pass to the outlets via tubes 50. When all the pistons attain their upper positions the solenoid 95 is actuated, and the valves are rotated so that liquids now pass via the inlets, bores 42 and tubes 50 to the spaces above the pistons and liquids below the pistons pass via the notches (43) to the outlets until the pistons all reach their lower positions and the lower switches are all closed. A pump 25 provides a suitable pressure difference between the inlets and outlets, although the pressure difference could be provided by alternative means. Different size spacers 52 may be used for different quantities of liquids.

Patent GB-219938-A (GB)
Abstract: 219,938. Felt & Tarrant Manufacturing Co., (Assignees of Turck, J. A. V.). July 31, 1923, [Convention date]. Transfer mechanism. - In multiple-bank machines in which the totalizer has a greater number of denominations than the keyboard, transfer from a lower to a higher numeral wheel is effected by a pair of differential epicyclic pinions to which an impulse is given at transfer and which by their epicyclic action cause movement of other gears to transmit an additional step movement to the next higher numeral wheel, the epicyclic pinions acting at other times as simple transmission gears. As shown applied to the machine described in Specification 219,923 in which the totalizer and transfer mechanisms are mounted in a laterally movable carriage, the differential actuating sectors 33 transmit their setting to pinions 111 associated with ratchet pinions 112, lantern wheels 113 and transmission pinions 114. Each pinion 114 gears with an externally and internally toothed wheel 131 loosely mounted on a hollow stub shaft 134 and connected by a pair of differential epicyclic pinions 141, 142 with a similar toothed wheel 130 that gears with the pinion 12 of the totalizer. The pinions 141. 142 are pivotally mounted on an arm 144 secured to a stub shaft 135 supported in the hollow shaft 134 and the hub 136 of the wheel 130. The wheel 130 is adapted to make a half revolution for each revolution of the numeral wheel. Each in wheel 130 is provided with arms 145 to which is attached one end of a transfer actuating spring 147 secured at its other end to a stud 148 on a plate 149 fixed to the stub shaft 135 of the next higher pinions 141, 142. The plate 149 supports a disc 150 and is provided with projections 153 one of which normally engages the end 157 of a corresponding spring-controlled retaining latch 154 pivotally mounted on a rod 155. Each latch is adapted to be released on each half revolution of the wheel 130 by means of one of a pair of cams 161 mounted on the arms 145. This cam engages a roller 160 on the latch to depress it so as to free the plate 149 which is thereby rotated under the action of the spring 147, the spring being wound up during each half revolution. Each of the discs 150 is provided with inward projections 152 which co-operate with the end of the corresponding latch to prevent it completing its half revolution if a cam 161 should, by delayed key action, hold the latch in any position other than the normal, the movement to normal being effected by the cam action of the projection 152. To prevent unwinding of the springs 147 when the totalizer carriage is raised for lateral shift, pivoted spring-controlled locking levers 163 are provided to engage the teeth of the wheels 131 when the carriage is raised, the locking levers being normally disengaged by reason of the arms 166 thereof resting on a ledge of a base plate 121. Specifications 13094/04, 26772/12 and 16036/13 are referred to.

Patent GB-222895-A (GB)
Abstract: 222,895. Jackson, W. J. Mellersh-, (Independent Radio Manufacturers, Inc.). April 5, 1923. Thermionic amplifiers. - In order to neutralize the effects of internal capacity coupling between the grid and plate circuits of a valve, a balancing capacity is connected in series with a balancing coil between the filament and plate. The balancing coil is closely coupled to the input coil in the grid circuit, and its number of turns bears the same ratio to those of the input coil as the internal capacity bears to the balancing capacity. Any oscillatory current that traverses the valve via the plate-grid capacity is thus balanced by a similar current through the balancing circuit. Fig. 2 shows the application to a multi-valve amplifier, with inter-valve transformers. The inter-electrode capacity is indicated by a condenser C<1>, shown in dotted lines, and is balanced by a condenser C<2> connected at one side to the plate 5 and at the other to a coil L<2> closely coupled to the input, coil L<1> and wound in the reverse direction. In a modification, the primary coil of the transformer 4 is utilized as the balancing coil, one side of the condenser C<2> being connected to the plate terminal of that coil. The condenser C<2> is thus directly connected between the plates of successive valves. The valves and transformers are preferably enclosed in metal boxes, and the leads may be sheathed. The system involves the general principle described in Specification 222,894, and may be applied tn power amplifiers for wireless transmission. Reference has been directed by the Comptroller to Specification 119,365.

Title: Improvements in or relating to labelling machines
Inventor: FAIREST DEREK HOWARD
IPC: B65C1/04
Filed: 1962-06-12
Abstract: 975,449. Labelling-machines. MORGAN FAIREST Ltd. June 10, 1963 [June 12, 1962; June 27, 1962], Nos. 22420/62 and 24594/62]. Heading B8F. In a labelling machine comprising a straight conveyer 4, Fig. 3, to support a spaced succession of articles A to receive a label on one side and another on an end at right angles to that side, a labelling bar assembly is made up of front and rear parts having suction label-holding pads which are movable with the parts in line to a position parallel to the conveyer and alongside an article, the front part being hinged to the rear part so that it can be swung to a position at right angles across the conveyer. The two parts are movable in line on arms 9, Fig. 4, rotatable about shaft 7 intermittently past two labelling stacks 12, 37 (not shown) and two gumming devices 18, 18A (not shown) and then to a position alongside the conveyer. When the front part is swung across the conveyer means 22 urge one side and the front end of the article towards the labelling pads. As shown in Fig. 6 the labelling bar assembly which is carried on each arm 9 has a spring- biased suction label-holding pad 15 pivoted by means of links 14 to a plate 10. The links 14 are carried by a push rod 27 movable lengthwise of the plate 10 by cam 28 to apply a gummed label to the side of an article. Simultaneously a rack 35 on the rod 27 in engagement with a pinion on the hinge of a bar 32 causes the latter to swing across the conveyer to a position at right angles and to apply a gummed label held on the spring-biased pivoted suction pad 29 to the front of an article. A plate 22 carried by links 23 is also simultaneously urged by a cam 26, Fig. 3, towards the article. The machine is also provided with a suction label-holding pad 44, Fig. 6, which is pivoted on a bar 42 hinged at 41 so as to be simultaneously actuated by bevel gears to swing over the top of the article, cam 49A acting on roller 49 applying the label. The bar 42 which is normally held at 135 degrees to the plate 10 (see Fig. 4) permits, on the rotation of the arms 9, the pad 44 to remove a label from a stack 48 which is then gummed by the roller 18. A suction valve controls the suction to the label-carrying pads to give a high suction for the withdrawal of the labels from the stacks which are reciprocated towards the pads, a lower suction to hold the pads until they are applied when the valve connects the pads to an exhaust. Microswitches 59 actuate the solenoids 60 to prevent the label stacks from reciprocating towards the pads and actuate solenoid 21 to hold the gum transfers rollers clear of the pads when the succession of articles ceases.
