Abstract: 445,307. Making tea &c. bags. HIRSCHHORN, L., and IRMSCHER, H., 288, Southern Boulevard, Bronx, New York, U.S.A. Oct. 11, 1934, No. 29101. [Class 94 (ii)] A machine for making tea &c. bags from textile material in tubular form, comprises means for guiding the material from source of supply to the machine, means for holding it against movement and means for creating slack in the material passing from the supply. Material in the form of a continuous tube wound on a spool 5, is drawn therefrom by a horizontally reciprocating frame 9 operated by a cam 42 on the main shaft 2, through an adjustable throw device 38, 44, 46. The tubular material, led over a plate 14 is opened at its leading end by flared spring arms attached thereto. Between the plate 14 and the spool is placed a slack-producing device comprising a camoperated spring-biassed gripper 21, 24 which holds the material whilst a cam-operated oscillating arm 33 produces the festoon 15. An intermittently rotated wheel 62 has arranged on its periphery pairs of journals 60, 61 for spring-biassed fingers 58, 59, operated in unison by a cam-operated plate 70, which fingers, on movement of the frame 9 to the left, enter the opened end of the tubular material which is maintained against motion daring the following movement of the frame 9 by a spring biassed presser foot. The cutting mechanism 6, comprising cam-operated spring- biassed shears, connected together through a lost motion device, now comes into operation to out off a predetermined length which is moved forward by the next movement of the wheel 62 to the sewing machine 7 which sews up one end of the tubular blank. The sewing- machine is carried by a frame 113 pivoted on a shaft 114, concentric with the wheel 62 which it turns intermittently upon actuation by a cam 121 through a link 116. The sewing- machine, driven continuously by a belt 122, is moved in such a way that there is always relative motion between the supporting frame 113 thereof and the wheel 62 to effect the sewing operation. The end to be sewed is pressed together as it enters the sewing machine by a stationary back plate and a pivoted front plate moved to contact with the material by the link 116. The bag is stated to be turned inside out before filling.

Title: Improvements in and relating to gramophone records
IPC: G11B3/70
Filed: 1931-10-28
Abstract: 391,457. Gramophone records. DIAMOND, S., 13, Crescent Road, Crouch End, London. Oct. 28, 1931, No. 29827. [Class 40 (ii).] An unbreakable gramophone sound-record is made by securing a photograph on each side of a basic ply or plies of paper, cardboard, or other material, with the photographic print facing outwardly and by covering each of the photographs with a layer of transparent cellulosic material, preferably non-inflammable cellulose acetate. All the plies are stuck together by adhesive and consolidated by heat and pressure when the sound track is impressed on the outer layers. Amyl acetate may be used on the surface of each photograph to secure the outer layers thereto. The amyl acetate combines with the gelatine of the photographic surface, dries out, and under the subsequent heat and pressure ensures a firm union without damaging the photographs. To seal the edges of the composite record the inner and outer peripheries of the outer cellulosic layers are cut so that the inner plies overlap slightly. This enables the uncovered edge margins of the inner plies to fuse with the adherent and seal up any gap between the plies. The photographs are preferably identified with the subject of the sound record. Specifications 17163/02, [Class 40, Electric telegraphs &c.], 247,429, 324,520, and 333,175, [all in Class 40 (ii), Phonographs &c.], are referred to.
