Title: Process and apparatus for ultrasonic cleaning of film
IPC: G03D15/00
Filed: 1959-09-08
Abstract: 909,423. Ultrasonic cleaning of film. LIPSNER-SMITH CORPORATION. Sept. 8, 1959 [Sept. 8, 1958], No. 13636/61. Divided out of 909,421. Class 98 (2). In a process for cleaning photographic film by passing it through an ultrasonically activated solvent, as in Specification 909,421, the movement of the film is offset with respect to the propagation vector of the ultrasonic agitation. As shown in Fig. 7, the tank 30 containing the cleaning solvent is fitted with two opposed ultrasonic generators 32, tuned so as to produce standing waves extending in vertical planes through the solvent. The energy loops and nodes are indicated generally as x and y respectively. The film 22 is passed in a helical path through the tank, offset so that the plane of the film forms an angle, both vertically and horizontally, with the plane of the standing waves. Thus, every part of the film surface will be exposed in turn to regions of maximum energy, and thus maximum cleaning effect. Also, the downwardly passing portion 22 of the film does not shield the upwardly passing portion 22<SP>1</SP> in the direction of wave propagation. In the alternative arrangement of Fig. 8, this result is also achieved by carefully orienting the falling and rising portions 22 arid 22<SP>1</SP> of the film. In this form, these portions travel in vertical paths. The guide roller 34 is angularly disposed (plane a) to the propagation vector b of the ultrasonic agitation caused by the generators 32 at an angle α, which may be 30 degrees. The roller 34, which can be raised or lowered, is of sufficient diameter to avoid shadowing of one parallel film strip by the other. The plate 164 of the supporting structure 156 carries the spray squeegees, also vertically movable, for partially removing surplus liquid from the film after it emerges from the tank. Specification 909,422 also is referred to.

Title: Improvements in and relating to a device for separating in a stacked record changer the lowermost record to be dropped upon the plate from the other records which must remain on the supports
IPC: G11B17/16
Filed: 1941-10-27
Abstract: 552,906. Magazine gramophones. PAILLARD & CIE. SOC. ANON., E. Oct. 27, 1941, No. 13772. Convention date, Nov. 23, 1940. [Class 40 (ii)] Relates to magazine gramophones in which a stack of records is supported above the turntable and one record is dropped at a time by the angular reciprocation of two arms 4, 7 cooperating with the edges of the records. It has been proposed to arrange the upper arm 7 to be wedged up if the normal spacing between the two arms is less than the thickness of the lowermost record. If the record next above is a large one, the whole stack above is also lifted by the arm until this arm comes over the lowermost record and can move in over it. This action causes considerable friction tending to wear the edges of the records. According to the invention, wear is prevented by making the arm 7 with a thin end 8, Figs. 2 and 3 beyond a rounded shoulder 6. The thin end 8 can always move freely under the edge of a large record e above a small lowermost record d until the shoulder 6 abuts the edge of the record e. Then the wedging action occurs lifting the arm 7 and the records above it until the arm 7 is raised just above the lowermost record d and can slide in over that record as shown in Fig. 1. Continued movement of the arms then cause arm 4 to release the lowermost record d; and on the return stroke of the arms, the arm 7 releases the stack and allows record e to fall on and be supported by arm 4 in readinesss for the next operation. As shown the arm 4 is fast on the rotatable post 5. The arm 7 is integral with a sleeve 12 loose on an extension 14 of the post 5 and is urged down by a spring 11. Balls 9, 10 are situated between the arm 4, 7 and co-operate to produce the wedging action. In addition an abutment 16 is provided to transmit the drive to the arm 7 when the balls are not in engagement.

Abstract: 593,608. Drum brakes. SCHNELL, S. June 8, 1945, No. 14581. [Class 103 (i)] Releasing means for a pair of brake shoes arranged to be applied to a drum comprises a single spring device which engages the adjacent ends of a pair of arms one integral or connected to each of a pair of levers which respectively carry the shoes. In one construction, levers 4, 5 pivoted at 6, 7 carry shoes 8, 10 that are applied to the drum 2 by a cranked lever 12 pivoted to the lever 4 and connected by a link 14 to the lever 5. The lever 12 is operated by a cylinder 18 slidable on a piston 20 fixed to a rod 21 pivoted at 22 to the base 1, pressure fluid being supplied by the pipe 24. The end of the rod 21 serves as a stop to limit the release movement of the cylinder and lever 12. Release of the shoes is effected by a leaf spring 28 which engages the adjacent ends of arms 26, 27, of which one is integral with the lever 5 and the other is freely mounted on the pivot 6 and engages the lever 4 by a screw 31. The clearance of the shoes relatively to the drum can be adjusted by the connecting means 17 of the link 14 to the lever 12 and by the screw 31. An additional release spring 25 may be provided. The spring device 26, 27, 28 prevents simultaneous lateral movement of the shoes which would bring one or other of the shoes into contact with the drum when the operating mechanism is in the release position. In a modification, a helical spring replaces the leaf spring 28, both of the arms 26, 27 are separate from the associated levers 4, 5 and the adjacent ends of these arms that are engaged by the spring have a pin-and-slot connection with each other.
