[Also in Division B2] Apparatus for spreading butter or like substances on slices of bread or likeshaped articles comprises a vertical pillar 1, Figs. 1 and 2, supporting a horizontal cylindrical casing 2 having a detachable end-cover 3. The casing 2 encloses a drum 6 secured to a horizontal tubular shaft 5, which passes through a bearing 4 in the pillar and is keyed to a gear-wheel 8 meshing with a gear-wheel 9 on a shaft 10 journalled in a movable bearing 28. The shaft 10 carries a crank handle 11 and a rubber-covered roller 27, which is urged towards a slot 26, in the casing 2, by a spring 29 pressing upwardly on the bearing 28. A fixed horizontal shaft 116, bolted to the gear casing 16, passes through the shaft 5 and carries a butter container 15. The drum 6 has a closable end-opening 117, through which butter can be inserted into the container 15 beneath a curved plunger plate 22. Mounted in arcuate plates 42 on the drum are movable pins 12, a desired number of which may be moved manually to engage and rotate a toothed wheel 13 on a horizontal spindle 14, mounted in the container 15. This spindle carries a gear-wheel 17 meshing with a gear 18 on a vertical spindle 19, rotatably supported in the container. The spindle 19 carries a screw 20, which engages a nut 21 secured to the plunger plate 22. The gears 8 and 9 are selected so that the roller 27 makes two revolutions during each revolution of the drum 6, which has perforations 25 in two, diametrically opposed areas 23 and 24. The roller 27 projects through an opening 30, in a table 31, successively to engage slices of bread placed thereon. The handle 1-1 is turned and a slice of bread is carried through the nip between the roller 27 and the casing 2 to receive, through the slot 26, a coating of butter, forced through the perforations 25, in area 23 of the drum, by the descending plunger plate 22. The drum turns through 180 degrees and the next slice then receives a coating of butter forced through the perforations 25 in area 24 of the drum. The plunger plate 22 may be returned to its uppermost position by clockwork mechanism, started by the actuation of a pin 37. The spring 40 of this mechanism is wound-up during the downward movement of the plunger plate. The apparatus may incorporate devices for giving an audible or visible signal, when the container 15 is empty, e.g. when the plunger plate 22 reaches its lowest position.

Abstract: 1,226,513. Coating apparatus. C. W. VOGT. 17 April, 1969, No. 19711/69. Heading B2L. Apparatus for evenly coating an article having a variably contoured surface comprises orifice means for delivering a flowing curtain of coating medium in a vertical plane, means for moving the article at a constant linear velocity in a generally horizontal direction, and means for maintaining a generally constant distance between the orifice and the portions of the surface on which the curtain impinges. As shown, platens 7 to 11 are secured to a conveyor chain movable in a horizontal elliptical path, and adjacent platens are hinged to one another as at 11, whereby two platens, such as 8 and 9, abut one another while passing under a pouring head 25 emitting a curtain C of coating liquid, the surplus of which is received in a supply trough 26 and returned to head 25 by a pump 27 and flexible line 28. The hollow interior of each platen is connected to vacuum means. The upper surface of each platen is formed with perforations 21 and is covered with a porous substrate S for supporting three rows of model motor cars A. Head 25 is pivoted at 32 between two arms 34, 35 which are pivoted intermediately on a spindle 36 carried by fixed vertical posts 37, 38 and which carry a counterweight 40 for head 25. A rotary shaft 50 carries a cam 46 formed with three lobes 51, 52, 53 each corresponding in shape to the profile of a car A. Cam 46 co-operates with a follower pin 55 carried at one end of an arm 56 pivoted at its other end at 57 to post 38 and connected intermediately by a link 58 to arm 35. Shaft 50 is driven at the rate of one revolution in the time taken for a platen to pass under curtain C, whereby the height of the latter remains constant to produce a uniform thickness of coating on cars A. The coating between adjacent platens is severed by a heated wire before the previouslycoated platen swings away from the platen undergoing coating. In a modification the upper surface of each platen is formed with three rows of recesses for receiving porous trays to be coated, and the profile of cam 46 is modified correspondingly.

Abstract: 1,234,507. Corner recognition. CALIFORNIA COMPUTER PRODUCTS Inc. 19 March, 1969 [28 March, 1968], No. 14526/69. Heading G4R. A system for recognizing corners in an outline represented by a succession of pairs of cartesian digital co-ordinates defining successive points of the outline,comprises means operativeon the digital co-ordinates to form digitally represented vectors extending between successive points of the outline, and arithmetic means operative to form the scalar product of the two vectors and determine the sign thereof to recognize obtuse angles as corners. If the scalar product of the two vectors is zero or negative, a corner is indicated. If the scalar product is positive, the ratio of the scalar product over the magnitude of the vector product (i.e. the cotangent of the angle between the vectors) is derived and if less than or equal to a predetermined value, e.g. 1 or 2, a corner is indicated. Only vectors of greater than a certain length are used, to permit corners to be recognized even if blunted, the corner being placed on the bisector of the angle between the two long vectors as near to their intersection as is consistent with not being at a distance greater than that between the near ends of the long vectors from either (a) the short vector in the ease of one short vector between the long vectors or (b) the junction of the short vectors in the case of two. The original outline coordinates may be entered manually or automatically, and application to the clothing industry is mentioned.
