Abstract: 991,466. Packaging-machines. PROCTER & GAMBLE Ltd. Oct. 16, 1961 [Oct. 14, 1960] No. 37076/61. Heading B8C. A controlled volume of granular material, e.g. a detergent, is delivered into open top pockets 5 having side walls, by moving the pockets continuously beneath a delivery means 6 from which the granular material issues continuously so as to form a ridge 10 of material in each pocket, each ridge having sloping sides 9 which intersect the side walls of the pocket below the top, the quantity of material in the ridge being constant because of the constant angle of repose of the material, the material in a ridge thereafter being distributed in its pocket. In Fig. 1, a drum has a row (or several parallel rows) of recesses 3 separated and surrounded by lands 16, 17, 18, 19, Fig. 4. A stretchable film of water-soluble material such as polyvinyl alcohol is led on to the drum and caused to adhere to the lands. Vacuum connections, such as 4, to the recesses form pockets in the film, which then pass beneath a hopper 6 which forms the ridge 10, Fig. 2. The volume of the ridge may be controlled by raising and lowering the hopper (bodily, or by pivoting it about an axis horizontally spaced from the hopper), by altering the width of the elongated aperture 7, or by adjusting a gate in the lower downstream face of the hopper, Fig. 3 (not shown). When more than one row of pockets are to be filled, a common hopper or individual hoppers may be used. Each pocket then passes beneath a scraper 20 having a resilient part contacting the lands, shaped as shown in plan in Fig. 4, and supported by the hopper, so that the material in each pocket is evenly distributed. A second water-soluble film is then led on to the first and sealed to it on the lands. The package so formed is then cut into individual pockets. Specifications 989,350 and 991,465 are referred to.

Windscreen cleaning mechanism includes a reversible electric motor adapted to drive a windscreen wiper when rotating in one direction and to drive a pump for spraying washing liquid on the windscreen and the wiper when rotating in the opposite direction. The shaft of a reversible electric motor 1, Fig. 1, has rigidly secured thereto a crank disc 3 provided with a crank pin 2 for driving a windscreen wiping mechanism (not shown). The shaft also carries an eccentric 7 having a hub 8 containing steel balls adapted to be wedged between cam surfaces on the shaft and on the inner surface of the hub 8 when the motor rotates in one direction, and to allow the shaft to run in the opposite direction without driving the hub 8. During each rotation of the hub 8 the eccentric 7 engages a leaf spring 10 to actuate the operating plunger 11 of a washer pump 12 to feed washing liquid to the windscreen. To ensure that on switching off the supply current thereto the motor 1 stops when the wiper is in the desired parking position an arm 4 rotatable with the crank disc 3 engages a spring contact 13 with a contact 14 at the desired parking position of the mechanism to short-circuit the armature winding of the motor when the main supply switch is in the off position. Various electrical control circuits are described. The arm 4 is coupled to the disc 3 by the engagement of a stud 5 on the arm in one of a series of slots 6, Fig. 2, in the disc. The parking position may be varied by moving the stud 5 to a different slot 6. The relative movement between the arm 4 and the disc 3 permitted by the length of a slot 6 ensures that the desired parking position is attained on stopping the rotation of the motor in either direction.
