[Also in Division H5] A patient is held during exposure in an apparatus comprising an X-ray transparent back wall a seat member on which a patient can sit with his torso against such a wall X-ray transparent means for holding the torso in that position, and an X-ray film cassette carrier which is located behind said back wall and is constructed so that the position in a plane parallel with said back wall at which a cassette held by said carrier can be adjusted, said wall, seat member and cassette supporting means constituting parts of a manually portable unit. Preferably the unit is constructed so that it can be hung on a bed head board or other suitable hospital or domestic feature. In a preferred embodiment fig. 2, the unit is shown comprising two separable portions, the patient supporting section and the cassette carrier section. The first section comprises a channel shaped section 1 of X-ray transparent material, the lower end being strengthened with a stainless steel plate 2 to which is attached and arm 3 projecting cantilever fashion from the back and being suitably covered to form a seat member. The upper part of section 1 is similarly strengthened but plate 4 is bent over to form a flange 5. The cassette carrier comprises a steel plate 8 bent over at the top to form a channel 9 which can be hooked on a suitable support. Studs 10 interact with slots 6 cut in flange 5 to correctly align the cassette carrier and the patient support. A transverse shelf 11 which supports standard cassette is movable in slots 12 along the length of the plate, being fixable by means not shown at a desired level. When fixed together the patient support and the carrier are spaced so that a cassette may be slipped between them. The patient may be restrained in position by strips fastened to the flanges of channel member 1, preferably the strips are made from a pile fabric which adheres to a strip 7 of similar fabric attached to the flange. The use of strips enables the breathing rythm of the patient to be observed by the radiographer.

Title: An arrangement for calling frequently wanted subscribers in an automatic telephone system
IPC: H04M1/278
Filed: 1959-12-08
Abstract: 898,198. Impulse transmitters. KANDA TSUSHIN KOGYO KABUSHIKI KAISHA, Dec. 8, 1959 [April 7, 1959], No. 41636/59. Class 40 (4). An impulse transmitter sends a complete multi-digit number in accordance with information sensed from a punched card. A card such as seen in Fig. 2 comprises four rows and each column registers a digit. The card is inserted between the contacts of a sensing slot CP and is clamped in position by magnet CM. Each set of four sensing contacts corresponding to a column is connected up in turn by a rotary switch RS. For each position of switch RS a particular combination of the relays A, B, C and D is operated which disconnect a particular number of sequential contacts of a wiper switch PG. Switch PG is driven by synchronous motor SM and during a revolution transmits a digit by pulsing a relay P and then steps switch RS to the next punch card column in preparation for transmission of a further digit. Having inserted a punched card, mechanically linked buttons SB1, SB2 are pressed causing relay R to operate and lock up and causing switch RS to step once by magnet RM and interrupter contacts rm. Off-normal contacts RC operate in switch RS and connect up motor SM which drives switch PG at the rate of one revolution in 1.5 seconds. With relay R operated the normal substation equipment Te is connected across line terminals L1, L2, with relay H in series. During the first revolution of switch PG relay P operates to all contacts 1 to 0 (but without effect) until contact SP is reached when relay S operates and locks up connecting the single contact of P across the line terminals L1, L2. The next contact RP of switch PG connects up RM which steps switch RS on to the next contact connecting up the first row of punched card sensing contacts. This determines a particular combination of relays A, B, C and D, which control the number of contacts 1 to 0 of PG connected to relay P and consequently determines the number of impulses sent out to line as PG makes a revolution. At the end of the revolution, having transmitted one digit, contact RP is encountered to step switch RS on to the next row of sensing contacts thus determining the digit transmitted in the next revolution of PG. At the end of the last digit RS steps on to a sensing row which for all cards reads the relays B, C, and D, and in so doing connects up relay Q which on the first contact QP of switch PG operates and locks up to drop relay S reconnecting the substation Te to the line terminals and disconnecting the impulsing contact of P. A contact of Q connects up RM to step switch RS home where off-normal contacts RC restore, releasing relay Q and disconnecting motor SM. Tones received from the called line are audible over loud-speaker SP and if, on reply, substation Te is brought into use relay H responds to release relay R and connection the substation across the line terminals.
