Abstract: 818,688. Containers for radio-active preparations. UHLHORN & CO. GES., E. Jan. 24, 1957 [Feb. 16, 1956; April 16, 1956], No. 2636/57. Class 98(1) An irradiation appliance has a rotatable carrier for radio-active preparations. As shown in Fig. 1, a bar-shaped radio-active preparation 3 is mounted radially on a disc 2 mounted at one end of a tube 1 and rotated by an electric motor 4 through a flexible cable drive 5, 6. The disc 2 may have a screwed connection to cable 6, so that it may be interchangeable with carriers of different shapes. The disc may be enclosed by a radiation-permeable or radiation filtering jacket 7, which may be formed with a guide bar 8 for insertion into a body cavity. The rotation of cable 6 may be observed by means of a mark thereon visible through a window 1a in tube 1, or by optical or acoustic means. In modifications, (1) the carrier may be conical, with the preparation mounted on the outer surface in a: plane of the axis; (2) the carrier may be conical or spherical with two or more preparations mounted on the inner surface; and (3) one preparation is mounted on the outside of a conical carrier, and another is mounted in a guide tube similar to tube 8, and is shielded by an adjustable cylindrical shield.

In a multistage switching network through which paths are sought with the aid of a memory map, in the event of a faulty crosspoint being detected either the intermediate link extending thereto or the intermediate link extending therefrom but not both is marked as busy in the map thereby rendering this crosspoint and either the row or column containing it together with the corresponding column or row of a matrix in a preceding or succeeding stage, to which it is connected by the busied link, unavailable during the path search. The map may be a centralized, link-free/busy store although it is suggested that it may be provided by a route simulating network. The switching network may be of the folded variety. The fault condition may be ascertained by a testing device which accesses each crosspoint individually in a routine manner.

Title: Improvements relating to magnetic transducers
IPC: G11B5/265
Filed: 1963-01-22
Abstract: 963,127. Magnetic recording &c. heads. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 22, 1963 [Jan. 22, 1962], No. 2695/63. Heading G5R. A transducer for magnetically recording in and reproducing from a magnetic record member comprises means for supplying a plurality of signals to be recorded to a plurality of electrically separate windings forming separate magnetic recording elements on a magnetic core structure, and a single magnetic reading winding on the core structure to reproduce the signals recorded by the recording elements. The core structure 11, Fig. 1, comprises a recording core portion 12 and a reading core portion 13. The recording portion includes a plurality of separate windings in the form of conductive strips 12b which are closely spaced on the pole face portion of the core to form a plurality of separate recording elements serially spaced in the direction of motion of the tape 16. A reading gap 13e is formed in the core structure, and reading coils 13c and 13d are mounted on core portions 13 and 12 respectively. The entire assembly is potted or encapsulated to form a rigid structure. When a key on keyboard 23 is actuated, a six-digit binary number corresponding to the selected character is transmitted to the write drivers 25 to supply current pulses to the strips 12b simultaneously, the tape 16 being stationary. After completion of the keyboard actuation the tape 16 is advanced to the next character position, and during the advance the recorded bits are read serially by coils 13c and 13d and pass through amplifier 21 to decoding matrix 30 which actuates a printer 31 on which a visual representation of the decoded character is produced for verification. Recording currents may produce undesirably large voltages in the read coils, and the amplifier 21 may be gated during recording. A conductor may be placed above or in the reading gap 13e and fed with the sum of the currents supplied to strips 12b to buck out some of the readback flux, Figs. 5 and 6 (not shown). In an alternative embodiment, Fig. 7 for use with read-back signals at low speed, a read coil 42 is disposed within the core structure 41. A. loop of wire 45 extends around the coil and through a probe 43 of high permeability magnetic material, and is connected to a source of high frequency current 44. The high frequency magnetic field established by the current flow through loop 45 modulates the flux in probe element 43 resulting from magnetisation of a bit to be read on the record medium; this modulation of the probe flux induces a voltage in read coil 42 which is supplied to amplifier 21.
