Abstract: 445,611. Photographic-film holders. BILLING, N. P., c /o London Laboratories, 6, Lower Regent Street, London. Oct. 15, 1934, No. 20968. [Class 98 (i)] A carrier for photographic films or other sensitive material having a support of thin flexible material, e.g. paper or celluloid, comprises two envelope elements one of which has one wall in the form of a mask and the other has an open end to receive the sensitive material, interengaging stops to prevent complete separation of the envelope elements being provided, one of which is in the form of a bent over flap on one element, the elements being made of paper or similar material. In the form shown in Fig. 3, the carrier consists of the envelopes 26 and 38, the envelope 26 having one wall formed with a masking aperture 25. The film 42 is mounted on a strip 35, one end of which is bent round to engage one margin of the aperture 25 as at 137. The inner envelope 38 is closed at one end and provided with a draw tab 39. To prevent complete separation of the envelopes interengaging flaps 40, 41 are provided. In one modification the strip 35 supporting the film is dispensed with, the film being held against withdrawal by an adhesive tongue on the outer envelope. Alternatively, an aperture is provided in the rear wall of the outer envelope and a seal 45, Fig. 12, passes through this and is stuck to the film at 47, the opposite end 46 being stuck to the inner envelope to prevent the parts being separated until required. In a further modification, the flaps 40, 41 are replaced by a bent up portion on the inner envelope, which engages the edge of the masking aperture 25 of the outer envelope when the inner envelope is withdrawn. The apparatus may be made in multiple form. Specification 423,035 is referred to.

Title: Traverse control mechanism in a ring spinning or twisting machine
IPC: D01H1/36
Filed: 1960-06-15
Abstract: 959, 949. Building-motion. MONSANTO CHEMICAL CO. June 15, 1960 [July 31, 1959], No. 21058/60. Heading D1D. A cam-actuated builder motion in a ring- spinning-frame comprises three levers, the first pivoted to oscillate in a vertical plane and having adjustable means for transmitting oscillatory motion therefrom in varying amplitude, the second attached to the adjustable means at right angles to the first lever and transmitting said varying oscillatory motion to a third lever connected to elements which lift the ring-rail. In Fig. 1, a first lever 10 is pivoted at 12 to be reciprocated by a cam 16. At each reciprocation, a pawl 28 pivoted at 29 to lever 10 and connected to a rod 32 with stops 34, 38 alternately engaging a fixed member, is oscillated intermittantly to rotate a ratchet-wheel 26 to rotate a threaded rod and move a nut 22 gradually towards the pivot 12. Nut 22 carries a second lever 24 which engages a third lever 42 connected by arms 44, 46 to a rotatably mounted shaft 48 connected by an arm 54 to a cable 60 secured to a quadrant 62. The latter is secured to a shaft 64 connected to a lifter-rod 72 through a bell-crank 84 and a foot and roller 74, 76. Thus, as lever 10 descends the ring-rail descends, and as lever 10 rises the ring-rail is lifted by a spring 88; during the oscillations of lever 10 the lever 24 gradually moves inwards pivot 12 so that the length of arc through which it reciprocates is gradually reduced, reducing in turn the extent of reciprocation of rod 72. By adjusting the position of arm 54 relatively to shaft 48, the shape of the cap can be varied. In other forms, the third lever is pivoted at one end, and directly connected to the cable 60 at the other; the lever has a flat top on which runs a roller connected to the second lever, and which has a switch operated when the roller completes its travel to switch-off the mechanism. In one such form, the pivot of the third lever is opposite the free-end of the first and the second lever travels towards the pivot of the first lever; in an other such form, the pivot of the third lever is disposed slightly forward of the pivot of the first and the second lever travels away from the pivot of the first lever.

Abstract: 970,087. Automatic temperature control. SIEMENS & HALSKE A.G. June 4, 1962 [June 16, 1961], No. 21455/62. Heading G3R. A temperature-sensitive network, which is connected to a temperature regulator through a transformer T, and amplifier V, comprises two circuits I, II supplied with AC from terminals 1, 2 and connected in opposition through the centre tap M of transformer T r . Circuit I includes a semi-conductor resistance thermometer R H  and resistances R 1  R 2  which are tuned to the characteristic of the resistance-temperature curve of thermometer. Circuit II includes resistances R o , R, and R of which resistance R has a slider S adjustable to control the nominal value of the regulator, the control scale being linear. In the balanced state the currents in the centre-tapped winding of transformer T r  neutralise one another and there is no output to amplifier V. When the temperature of thermometer R H  deviates from the nominal value a differential voltage occurs at transformer T r , the phase of this voltage depending on the direction of the deviation from the nominal value. A corresponding signal is produced by the amplifier until balance is restored by operation of the regulator. The control resistance R may be located remote from the network. The effect of other quantities associated with the regulator may be included by providing the network with additional supply circuits or the transformer T r  with additional primary windings.
