Title: Article storage and retrieval apparatus
IPC: G11B15/68
Filed: 1974-05-01
Abstract: 1433097 Conveying tape cartridges INTERNATIONAL BUSINESS MACHINES CORP 1 May 1974 [29 May 1973] 19024/74 Heading B8A [Also in Divisions G3 and G5] Articles, e.g. magnetic tape containing cartridges 12 on a continuously rotating carrier 10, are withdrawn from the latter for processing in a unit 22L or 22R by a member 30A. A speed control unit (see Division G3) causes acceleration of a motor 68 driving the member 30A, so that it meets the selected cartridge at a speed equal to that of the carrier 10. Instead of the member 30A serving two units 22L, 22R, there may be four members 30 spaced around the periphery of the carrier 10 (Fig. 1) each being associated with a respective member 30. Instead of the carrier 10 being a circular carrier, it may be in the form of an endless belt. Each cartridge has an axially projecting annular edge 32 at each end (Fig. 11). These edges are engaged by projections 44 (Fig. 2) at the moment of transfer, and are retained by spring loaded plungers 43 (Fig. 2A, not shown). At the unit 22L or 22R grippers 206 have a reciprocating movement towards and away from the member 30A so as to engage and detach the cartridge and drop it into an aperture 208 in the processing unit. Subsequently, the cartridge (when its tape has been processed) is raised in the aperture 208, gripped again at 206, 207, and returned to the member 30A, which returns it to its correct location in the carrier 10. In the modified rotary carrier modification (Fig. 1, not shown) the member 30A is replaced by a member 30 which is double ended (this type is shown in Fig. 9) and when one end is carrying a cartridge from the carrier to the processing unit, the other end is taking a cartridge with a processed tape, back to the carrier 10. In a further modification (Fig. 7) the rotor comprises a stack of carriers 10, 10A 10B &c. A single member 30 serves all the carriers by being mounted, in addition to the rotation already described, for movement up and down a lead screw 14 and guide 116.

Title: Improvements in or relating to sprinkler systems
IPC: A62C35/64
Filed: 1923-07-25
Abstract: 217,079. Jackson, W. J. Mellersh-, (General Fire Extinguisher Co.). July 25, 1923. Sprinklers, automatic. - Dry-pipe sprinkler systems are so constructed that the dry-pipe valve is caused to open upon any drop of pressure to a predetermined extent or upon a slight quick drop of pressure not necessarily reaching the predetermined extent. A pressure-sensitive device subject on one side to the pressure in a chamber communicating with the dry pipe by a restricted opening operates a valve to admit fluid under pressure to the chamber 10 between the air valves 5 and the water valve 7 of a differential type valve. On the opening of a sprinkler the pressure in pipe 40 and bellows 38 falls quickly, but the, pressure in bellows 39 in communication with the dry pipe by an air chamber 12, chamber 31, and pipe 13 falls slowly owing to the restricted orifice 14 in the chamber 31; the bellows thus move a bar 42, and a weighted lever 19<1> which opens a valve 18<1> by a finger 21. In this way the chamber 16<1> which is connected to the water supply pipe 4 by a pipe 17<1> is put into communication with the chamber 10 by a pipe 15<1>. In a modification in which air pressure is supplied to the chamber 10 the pipe 17<1> connects the chamber 16<1> to the air pipe 2 and the weighted lever 19<1>, operating the valve 18<1>, is moved by a, plunger and a rubber diaphragm. supported by a perforated plate in communication with the air chamber 12 on one side, its other side being subject to the pressure in chamber 16<1>. The chamber 31 is provided with a strainer 37 to prevent the orifice 14 from being choked. An open drip attachment 11 which normally maintains atmospheric pressure in the chamber 10 is closed by pressure. Reference has been directed by the Comptroller to Specification 221,602.

Abstract: 459,177. Television. BAIRD, J. L., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. July 4, 1935, No. 19121. [Classes 39 (i) and 40 (iii)] Relates to a television or like system in which electron beam scanning devices are employed at the transmitter or receiver and consists in a method of scanning in parallel lines or strips the inclination of which to a datum line is periodically changed. According to one aspect of the invention, traversal is effected in groups of parallel bands or strips, the inclination of the bands or strips within a group being the same, but the inclination of the bands or strips in different (e.g. successive) groups being different. As shown in Fig. 1, the connections from two time base oscillators 1, 2 to deflecting plates 3, 4 in a cathode - ray tube 5 are periodically reversed by means of a commutator device 6 driven by a motor 8, i.e. each time base oscillator is connected to each pair of deflecting plates alternately. The oscillators 1, 2 may be synchronized in the usual way by signals from a receiving device 9 and the motion of the motor 8 may also be synchronized by signals from this device. Alternatively, the device 6 may be replaced by an electrical contact making relay operating as a reversal switch and this relay operated by means of a cathode-ray beam adapted to sweep over a series of contacts in a cathode-ray tube which replaces the motor 8. Fig. 2 shows an alternative arrangement in which the tube 5 is mounted in a holder 10 adapted to be rotated through suitable gearing by a motor 11, supplies to the tube being fed through a series of slip rings 12. This embodiment may be modified by rotating only external deflecting means, such as magnetic coils. According to a further modification, the cathode-ray tube or external deflecting means only may undergo a reciprocating motion. Specification 289,307, [Class 40 (iii)], is referred to.
