Title: Improvements in or relating to methods of and apparatus for dispensing predeterminedweights of material
Inventor: HIGHAM EDWARD HALL
IPC: G01G3/142
Filed: 1956-07-05
Abstract: 848,330. Electric control systems. UNILEVER Ltd. Oct. 4, 1957 [July 5, 1956], No. 20926/56. Class 40 (1). Apparatus for dispensing a predetermined weight of material comprises a weight-sensitive electrical element (e.g. a resistor strain gauge; a variable inductance) in a bridge circuit; when a first load unbalances the bridge, a first adiustable component thereof is automatically varied to restore balance, a calibrated component having a first setting; the unbalance caused by a second load is automatically corrected by operation of a second variable component, the calibrated component having a second setting; and the flow of material is subsequently controlled by means responsive to the bridge current. As shown, Fig. 1, when an empty container 2 is placed on a platform 1 supported by a load-carrying member to which is secured a multiple resistor strain gauge 3, comprising four strain gauges 17-20 (Fig. 2) connected in a modified Wheatstone bridge arrangement, a detector (not shown) energizes the bridge circuit and causes a switch 8 to connect the bridge output to a servo-system 9, which drives, via a clutch 10, the wiper of a calibrated potentiometer 7 to one end of its path, representing zero, and then drives a variable resistor 5, shunted across strain gauge 18, to rebalance the bridge. Switch 8 operates a motor 16 to rotate a cam 15 to suspend a standard weight 13 from the load-carrying member, the bridge signal thereby produced operating, via servo-system 9 and clutch 10 to drive the potentiometer wiper to the other end of its path, and then to restore balance by altering a variable resistor 6 which is shunted across the potentiometer. The standard weight 13 is lifted from its suspended position, and the bridge output is now fed to a flow controller system 11 which operates to dispense material into the container 2 until balance is restored, the weight of the dispensed material being between zero and the standard weight, depending on the pre-set position of the potentiometer slider. Conveyer mechanism (not shown) then replaces the filled container with an empty one. The range of the apparatus can be increased by moving the potentiometer slider over only a fraction of its path between the first and second balancing operations. The resistance of variable resistor 6 should be high relative to that of the potentiometer 7, so that the first balance condition is not substantially upset by the second balancing operation. The apparatus may be used to allow a predetermined weight of material to be dispensed from a container, which may form part of the load-carrying member.

Abstract: 239,202. Nagel, A. Aug. 26, 1924, [Convention date]. Actuating by electromagnets; regulating delivery by varying speed and power of motor. - Consists in a particular form of alectric switch for causing the continuous reciprocation of a pump piston b and in locking means for preventing operation of the pump when the liquid supplied, by the pump has reached a. certain level. The piston b of the pump is also the core of an electromagnet a having two windings. With the parts in the position shown in the Figure, a circuit is completed through the left-hand winding. The. core b is attracted to the left till it strikes an end plate c. The increased flux then attracts the left-hand one of two armatures connected by a rod d causing the rod d to move to the right and stress a blade spring c<1>, which forms one arm of a threearmed member e<1>, e<2>, e<3>. The arm e<2> is prevented from moving till a pin e<5> on it which engages the upper surface of a member d<3> fixed to the member d is released by the latter whereupon the arms e<2>, e<3> rotate and the arm e<3> moves from a contact k<1> to a contact k. A circuit is now completed through the right-hand winding. causing the attraction of the core to the right and the movement of parts back to their original position. The locking means comprise a float f the rise of which stresses a blade, spring i<4> tending to rotate a disc i and place a finger i<3> in the path of the arm e<2> to prevent operation of the switch. Rotation of the disc i is prevented by a tooth g<1> till the rise of the float cause a pin f<2> to engage an arm g. The switch is similarly unlocked when the float f falls to a predetermined level. Specification 225,829 is referred to.

Abstract: 1,107,569. Safety harness. SIGMATEX A.G. 20 May, 1965 [21 May, 1964], No. 21302/65. Heading A3V. [Also in Division E2] In a vehicle safety harness a chest strap 10 and a lap strap 12 are anchored on one side of a seat, Fig. 1 not shown, and are detachably connectible to an anchorage on the other side of the seat by a common buckle 16 in which both straps are passed round a bar 18 movable at a pull on either strap to clamp it against abutment 17d, 17h. The bar 18 is biased towards the clamping position by a spring 19 which also urges a latch member 23 into a position to snap into engagement with a locking tongue (15) mounted directly, or by means of a further strap, on the vehicle floor, Fig. 1 not shown. The bar 18 is movable out of the clamping position by means of a sleeve 26 through the engagement of a pin 20 on the bar with slots 28 in the sleeve. The sleeve also actuates the latch member 23 through an abutment 27, the lost motion pin and slot connection allowing the sleeve to be moved to release the clamping means without unfastening the buckle and vice versa. Forms of buckle fastening other than the locking tongue 15 and shoulder 24 are contemplated. The strap ends pass through clasps 22d, h slidable on the main portion of their respective straps and/or the straps may be integral and carry a grip (35) (Fig. 1) to enable both straps to be adjusted simultaneously. In the former case the material of the two straps may be capable of different degrees of elongation. To adjust only one of the straps its free end may be pulled which straightens the strap adjacent the abutment forcing the bar away therefrom. If, in order to lean forward, the user moves the sleeve 26 to unclamp the chest strap, his own inertia will act to clamp the lap strap in the event of a collision. A spring retraction mechanism may replace the fixed anchorages (11) and (13), Fig. 1, or the straps may be detachably mounted on these points. In a simplified embodiment, Fig. 6, not shown, both straps pass round a slidable bar (31), non- rotatably mounted in a locking tongue (30), forming a loop (29) as in Fig. 1 not shown, and pull on either strap in e.g. a collision clamps the continuous strap length against an abutment (33). Pull on loop portion (29a) or (b) or both shortens one or both straps and finger grips (34) on the bar (31) permit it to be pulled away from the abutment (33) to allow extension of one or both straps.
