IPC: C09B45/20
Filed: 1956-08-21
Abstract: 3 - Amino - 4 - phenol sulphonylmorpholine is made by treating 2-chloronitrobenzene with chlorosulphonic acid and the sulphonyl chloride thus obtained with morpholine to yield the corresponding morpholide, the chlorine atom of which is replaced by a hydroxy group by reaction with caustic soda before reduction of the nitro group with sodium sulphide to give the desired amine.ALSO:The invention comprises 1,2-cobalt complexes of dyestuffs of formula <FORM:0825606/IV(c)/1> where R1 is H, Me, Et, MeO, EtO or methyl-, ethyl-, dimethyl- or diethyl-sulphamyl and R2 is Me, Et, MeO, EtO or methyl-, ethyl-, dimethyl- or diethyl sulphamyl.  Dyestuffs of the above formula are made in conventional fashion by coupling a diazonium salt of 3-amino-4-phenol sulphonylmorpholine with an appropriate acetoacetanilide.

Abstract: 534,835. Order-telegraphs. AKTIEBOLAGET GOTAVERKEN. Sept. 16, 1939, No. 25961. Convention date, Sept. 17, 1938. [Class 118(ii)] An order-telegraph system comprises a movable control member for controlling the engine, means for repeating the orders received, and means adjusted by the repeating-device for preventing the control member from being moved in the wrong direction, the repeating device being arranged co-axially with the control member. The apparatus comprises a pointer 1, Fig. 1, which indicates on a dial 3 signals from a transmitter, and another transmitter 7 which repeats the signals on another receiver near the original transmitter and also rotates a repeating-wheel 10 mounted in front of a dial 5. A wheel 4, also mounted in front of the dial 5, is secured to a shaft 11, Fig. 2, which has a U-shaped section 12 and carries known means for starting, reversing &c. the engines. The repeating-wheel 10 is secured to a shaft 16 which is journalled in the shaft 11 and carries a grooved wheel or sprocket 17 by which it is operated from the transmitter 7. A member 18 is slidable longitudinally along the shaft 11 and along a guide stud 19. This member has parts 20, 21 with circular cam grooves 22, 23, Fig. 4, respectively, on their inner surfaces which can be engaged by projection 24, 25, respectively, on the wheel 17. In operation, when a signal is indicated by pointer 1, the engineer repeats it by turning the transmitter lever 7 and the wheel 10, and thus rotates the wheel 17. Movement of the wheel 17 causes the projection 24, 25 to force the member 18 to one end of the other of its range of movement along the stud 19. In either position, an abutment 28 or 29 on its outer surface engages one of the arms 30, 31 of the section 12 of the shaft 11 and prevents the control wheel from being turned in the wrong direction.

IPC: H04M3/523
Filed: 1954-09-10
Abstract: 773,374. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. June 28, 1955 [Sept. 10, 1954], No. 26230/54. Class 40 (4). Bidirectional demand selectors of the kind described in Specification 459,803 (Figs. 2, 3) which give access to trunk operators' connecting circuits and queue on their tenth levels when no connecting circuit is available are arranged (1) to step to the tenth level upon seizure even when a connecting circuit is available, and (2) to step into the queue (when there is one) in two stages in the manner described later. When the selector shown is taken into use, it steps immediately to the tenth level when PA energizes over vertical wiper AW and post springs NP operate to connect relay Q to lead 12. Assuming first that a connecting circuit is available, lead 12 is earthed and relay Q energizes and connects up change-over relay CDD, with the result that the selector steps over the tenth level and returns to normal in "rectangular" fashion. Relay CDD restores, and since Q remains locked the selector hunts vertically and then rotarily for an idle connecting circuit. Relay CO energizes over the loop when HA or HB switches through and connects up RB which holds release relay B independently of the caller. On a call from a coin-box CBB is operative and connects up a tone from lead 17. In this case CO is energized by battery on the + wiper. If the caller is required to hang up he may be recalled by the operation of ringing relay RR in response to interrupted battery on the + wiper. The caller controls a supervisory signal over the S wiper, and the operator releases by removing the holding battery from the P wiper. If the call is initiated when the queue of waiting calls is full, there is no earth on lead 12 and the selector remains in a " congestion" position with its wipers clear of the contacts of the tenth level. Relay HA energizes and operates an unanswered call indicator over lead 15. When a vacancy occurs in the queue, earth is replaced on lead 12, Q and CDD operate and the selector takes one step to a " pool " position in which PA energizes if there is battery on lead 16 with the result that the selector steps into the queue only when battery is removed from this lead. Circuits are des. cribed, Figs. 3, 4 (not shown), whereby waiting selectors are admitted to the queue from the pool position in succession as vacancies occur in accordance with their location on the rack and the position of the rack in the suite of racks. When no selectors occupy the pool position, the next vacancy allows all the selectors in the congestion position to advance to the pool position, and one of them is admitted to the queue.

Abstract: 1379344 Micro-imaging reader N C R CORP 4 June 1973 [12 June 1972] 26478/73 Heading G2J  A micro-image reader has a grid-like member positioned in the optical projection path, together with indicator means associated with the grid and movable relatively thereto, such that relative movement between the member carrying the  micro-images and the reader lens assembly brings about relative movement between the indicator and the grid to indicate on the latter the portion of the micro-image member which is being read, adjustable aperture means also being  provided which can be adjusted between a first position in which a shadow image of the grid and indicator is cast on the viewing screen and a second position in which the shadow image is so out of focus as to be substantially undiscernable. As shown, light from a source 16 passes through the microfiche assembly 28 and a projection lens assembly 22, and is reflected by mirrors 24, 25 on to the viewing screen 26. Assembly 28 is carried in a holder (30), Fig.2 (not shown) movable in X and Y directions. Between lens assembly 22 and mirror 24 is a rigidly held transparent plate 40 carrying a grid pattern marking 42, 44. Adjacent plate 40 is a pair of cross-hairs 46, 48. Just above light source 16 is a slidable plate 62 with a series of apertures 63, any of which can be aligned with the light source. Thus an image of the aperture is formed between lens 22 and the grid, which in turn acts as a point source illuminating the grid and projecting its shadow on to the screen 26. When the aperture is drawn out of alignment with the light source, the grid pattern is blurred and does not show up on the screen. The intersection point of the cross-hairs indicates on the grid the position of the particular image on the fiche which is being viewed, and the cross-hairs are arranged to move in correspondence with the movement of the fiche. The fiche has wipers (141, 156, Fig.11 (not shown) which move along resistors (142, 157) potentiometer fashion as the fiche moves. The change in the resistances actuates the pointer of a meter which is connected to a cross-hair, which moves correspondingly.
