Title: Data Collection Installation
IPC: H04M3/523
Filed: 1967-04-26
Abstract: 1,186,603. Selective signalling. KABELUND METALLWERKE GUTEHOFFNUNGSHUTTE A.G. 26 April, 1967 [30 April, 1966], No. 19264/67. Heading G4H. Remote stations are connected to a central station over a common cable, each remote station can be switched independently to a waiting-state ABC by operation of a push button T or a remote signal t, the waiting stations being switched in for data transmission in a predetermined order along the cable under control of the central station. Positive potential applied on line P from the central station picks up relay B in the first waiting station along the cable to select the transmission state ABC and data is transmitted serially or in parallel over contacts of B (not shown). Opening of b2 removes the positive potential on line P from all downstream stations, and the central station applies positive potential to S on receiving positive potential over D1, a2, b1, b3 and S. When the transmission is complete, positive potential on Y is interrupted by the central station, A drops out to apply positive potential on the downstream section of P over S, b3, b4 and a4, the next downstream waiting station picking up its relay B and taking over transmission as above. Momentary interruption of negative potential on Z releases B to reset the station which has completed its transmission. The central station -may include a data checker e.g. a bit counter providing a check symbol for punching at the end of a block of recorded data, and negative potential may be applied to line X on detecting an error in the received data so that C picks up in the station in the transmission state ABC, A and B drop out and an error is signalled. Relay C is released when button T is pressed for a fresh transmission.

Abstract: 471,624. Gas holders. KEAY, Ltd., E. C. & J., SHELLEY, T., and GERRARD, J. July 13, 1936, No. 19357. [Class 54] A guide carriage a for spirally guided gas holders is formed with upstanding flanges d supporting the axles e of two rollers b engaging the opposite sides of the guide rail c, the bearing holes f in the front flange d being elongated to allow a limited movement of the axles towards each other under the pressure of an adjustably weighted crank h which is connected by links g to the axles. The bearings in the rear flange d may be formed by similarly elongated holes but preferably the holes are made circular to receive the reduced ends of the axles, the shoulders m between the reduced ends and main portions of the axles being made convex to allow the axles to rock. Axial movement of the axles is prevented by staples n which straddle the rear flange and enter transverse holes in the axle, but axial movement of each roller is permitted within the limits of the engagement of a collar k on the axle with the inner face of a chamber in the roller and an end plate l secured to the roller.

Abstract: 1,267,414. Electro-photographic apparatus. RICOH K.K. April 17, 1969 [April 30, 1968 (5)], No. 19615/69. Heading G2H. A marginally perforated web 1, having a photoconductive coating, unwound from a roll is electrostatically charged by a wire beneath rollers 3, 4 before exposure to a cathode ray tube 16, another electrical information signal display arrangement which forms a latent image on the photo-conductive coating developed by passage through a tray 57. A feed roller 8 having sprocket teeth 10 feeds the web to a guide plate 11 above feed roller 12 and 14. A roller 20 feeds the web intermittently past the cathode ray tube 16. A shaft 34, Fig. 2, driven by the shaft 9 of roller 8 has a cam 39 engaging a gear 37. The gear 37 is rotated when in engagement with a portion 38a, Fig. 3, of the cam, but is stationary, during exposure, when opposite portion 38c. Alternatively, the roller 20 is driven intermittently by worm gearing, Figs. 6 to 8 (not shown). A pump 59, Fig. 1, supplies developer solution from a reservoir 19 through a pipe 60 to the tray 57. Excess developer in the tray 57 overflows and returns to the reservoir. The tray 57 is vertically adjustable to control the length of web immersed and therefore the developing time. A slack-forming member 54 prevents irregular feed of the web 1. The member 54 is actuated upon operation of a rocking arm 5 so that the member 54 takes up position 54A to form a webloop which is maintained during operation. A cleaning pad 65 engages roller 21 to remove dust, toner etc. A blower 66 supplies dried air through ducts 67, 68 on to the developed sheet.

In a high-pressure elastic fluid turbine, wherein an inner shell 3 which carries the stationary blading and surrounds the turbine rotor 4, is surrounded by an outer casing 1 so that an annular space is formed in communication with the turbine exhaust, the turbine casing 1 comprises an undivided cylindrical shell 1 closed at one end by an end wall 2, the inner shell 3 is subdivided along the axial plane and solely supported in a cantilever fashion by the end wall which is also provided with an annular channel 11 for the supply of working fluid and an annular projection which co-operates with the projection 10 on the casing 1 to form a tight seal. The rotor 4 is mounted on a pedestal 6 bearing and a bearing 5 supported from the wall 2. The shaft is sealed at the high-pressure end by an axial labyrinth seal 7 and a radial labyrinth seal 8 and at the low-pressure end by a radial labyrinth seal 9 only. The arrangement is such that the two radial labyrinth seals seal the same pressure difference so that they may have the same diameter and same dimensions and thus the axial thrusts due to them will be balanced. The motive fluid from the channel 11 passes through passages controlled by valves 13 to the nozzles 15. The discharge channels 19 are designed to diffuse in the axial direction to reduce exhaust losses. The wall 2 and inner shell 3 are provided with channels 21 to conduct leakage from the axial high-pressure labyrinth to an intermediate stage of the turbine.

A free-running pulse-generator circuit comprises two emitter-coupled transistors provided with a regenerative direct-coupled connection from the collector of one to the base of the other and a degenerative feedback path from the emitter of said other transistor to the base of the first-mentioned transistor, the said feedback path comprising a series resistor, a shunt capacitor connected between the path and a point of fixed potential and a diode gate controlled by the potential difference across the capacitor whereby when the circuit is in one state with one transistor conducting and the other non-conducting that state is maintained by the regenerative coupling until the shunt capacitor has either charged or discharged to such an extent that the degenerative feedback applied through the diode gate to the base of the first-mentioned transistor is such as to overcome the regenerative feedback and produce a change of state in the circuit, a similar action then taking place when the charge on the capacitor has once more reached a value sufficient to overcome the regenerative feedback so that the circuit switches continuously between its two states of operation. In the circuit illustrated, when transistor T2 conducts its emitter goes negative with respect to its value when the transistor is non-conducting. Hence when transistor T2 conducts capacitor C1 charges negatively until the voltage at the base of transistor T1 falls sufficiently to permit transistor T1 to conduct. Transistor T2 is thereupon cut-off by the cross-connection from T1 to its base electrode and the output at E goes relatively positive. Diode D2 is cut-off and capacitor Cl discharges through resistor R6 until diode D1 conducts to divert base current for transistor T1 into the capacitor C1 whereupon T1 is cut-off and transistor T2 conducts once more. By the application of a suitable negative voltage at F, capacitor C2 may be effects ely connected in parallel with capacitor C1 to provide an alternative frequency of oscillation.
