IPC: G11C11/44
Filed: 1961-01-16
Abstract: 967,191. Digital data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 16, 1961 [Jan. 19, 1960], No. 1692/61. Heading G4C. A current flowing in conductor 38 sends superconductor 30 resistive and directs current through superconductors 32 and 34. The current through the latter sets up a magnetic field acting on an element 40 which is then capable of rotating the plane of polarization of a beam of light reflected from the element. Such a rotation is detected by filter 58 and photo-cell 60. The element 40 may be a ferromagnetic when a biasing coil 42 is necessary. Materials listed are cerous oxide, highly doped glass, ferromagnetic garnets (yttrium, erbium, samarium and gadiolinium iron), cerous nitrate and paramagnetic salts. The beam of light is preferably from a flashing source and may pass through the element. The read out system obviates the necessity of conductors from the low temperature bath containing the cryotron and thus cuts heat losses.

Filed: 1962-01-19
Abstract: 973,226. Mouthpiece cigarette-making machines. J. A. RAKOWICZ, and MOLINS MACHINE CO. Jan. 18, 1963 [Jan. 19, 1962], No. 2036/62. Heading A2C. In a mouthpiece cigarette making machine, in which two cigarette components are united to an intervening mouthpiece portion by a uniting band to form a group which is severed centrally to produce two complete mouthpiece cigarettes, apparatus is provided for rejecting and separating the components of a non- united group such that the centre component (i.e. the mouthpiece) is segregated from the end components (i.e. the cigarette part) into separate receivers. A cigarette mouthpiece group is united by band B in rolling passage formed by stationary surface 2 (Fig. 1) and rotating drum 3 to form group G which is transferred by cylinder 5 to clockwise rotating rejector drum 10 in which it is held by flutes 12, until it reaches the "3 o'clock" position when the group come to be supported by the concave supporting surface 13. Surface 13 consists of 6 main parts including two guides 14, 15 (Fig. 2) with chamfered ends 35, 36, anchored at 20, 21, the guides being so spaced that the centre line of each is approximately coincident with the vertical line through the centre of gravity of each cigarette length; guides 16, 17 fixed by pins 22 to guides 14 and 15, and spaced such that the inner edge of each guide lies outside the vertical line through the centre of gravity of each cigarette length and continuation guides 18, 19 spaced as guides 14, 15. When a cigarette mouthpiece group reaches guides 14, 15, if the united band B is faulty, the mouthpiece M falls into receiver 33, and the two cigarette lengths are carried to guides 16, 17 where because of the wider spacing they are rejected and fall into receiver 34. The satisfactory groups G are carried over the surface 13 via guides 18, 19 and assisted by stripping fingers are transferred to cutting cylinder 28, on which the cigarette group is divided to produce two mouthpiece cigarettes. If a centre mouthpiece is not stripped from cylinder 5 with its flanking cigarette lengths it continues round cylinder 5 until stripped by fingers 37 below which is positioned plate 38. The rejected component slides over plate 38 and drops into receiver 33.

Filed: 1923-11-08
Abstract: 229,234. Rotinoff, A. G. Nov. 8, 1923. Piles; piles, driving.-A hollow casing constituting a pile or the casing of a pile is provided internally with a screw thread to engage with a corresponding external thread on a driving core or tool, and is made of concrete, reinforced concrete, or similar material, with or without fibre, such as asbestos, worked into it. The shell may have a smooth exterior, and is preferably provided with means such as a longitudinal external projection or a longitudinal slot or both to prevent rotation in the ground when unscrewing the tool. Its cross-section at any point may be a figure not corresponding with its circular inner periphery for the same purpose. The casing 10, Fig. 1, is provided internally with a screw thread. 11 and adapted to be screwed on to a tool 12 which is hollow and constructed so as to permit the driving impact of the monkey to be delivered at about its centre of gravity. A corresponding thread 13 is formed on the tool, and the depth of the. groove in the casing is less than the projection of the thread on the tool so that the bodies of the tool and casing do not come into contact. The section of the groove in the casing is larger than that of the thread on the tool for the purpose of facilitating the initial unscrewing movement by lifting the tool slightly. The groove in the casing has a susbtantially horizontal lower surface so that there is no tendency to burst the casing in driving. The casing may be made in semi-cylindrical sections 14, 15, Fig. 2, provided with longitudinal flanges 16, 17, which form a key preventing rotation in the ground, and which are utilized to secure the sections together by means of a channel section clip 18. The casing may also be divided transversely as at 19, Fig. 1, thus enabling the separate parts to be assembled on the tool during the driving operation.

The member 22 is pivoted on a fixed lug 18 together with a second actuating element 24, which supports the swtich 60 for movement therewith and has a projection 54 for the actuation of a third electric switch 58. The switches 38, 58, 60 and fluid pressure actuators 6, 8 of the bellows type are arranged in a refrigeration system whereby the switch 38 and bellows 6 detect a maximum pressure on the high pressure side and the switch 58 and bellows 8 detect a minimum pressure on the low pressure side for stopping the refrigerator motor. When the high pressure in the bellows 6 drops and the low pressure in bellows 8 rises so that the pressures approach each other a projection 34 on member 22 approaches the pin 62 of switch 60 on the member 24 to actuate the switch 60 and start the refrigerator motor. The two bellows 6, 8 are opposed by compression springs 40, 64, Fig. 1 which are simultaneously adjustable by threaded abutments (70) on screws (74) Fig. 1 (not shown) driven through gears (78), (80), (82) from a common slotted adjustment head (84). Additional resistance to the movement of the member 22 is provided by an abutment plate 46 loaded by a compression spring 42 with a further adjusting screw 76. A threaded abutment rod 48 limits the effective movement of the plate 46 to the hgher pressure range. The downward movement of the member 24 is resisted by a tension spring 66 having an adjusting screw 67.
