Title: Improvements in or relating to time-division multiplex switching systems
IPC: H04Q11/04
Filed: 1961-06-09
Abstract: 981,336. Automatic exchange systems. SIEMENS & HALSKE A.G. June 9, 1961 [June 10, 1960], No. 20933/61. Heading H4K. In a pulse multiplex exchange system the multiplex cycle contains a pulse position additional to those used for speech connections, this position being used to supervize the off-hook condition of each subscriber in turn. Communication is established over a two-way speech multiplex SM via gates S1 . . . Sx opened by pulses at a speech time position allotted to the call and stored in combinations of delay lines Ua (calling subscriber) and Ub (called subscriber), the combinations being decoded at Da, Db for pulsing leads individual to the subscribers. Register G is stepped cyclically once per multiplex cycle to register the coded identities of the subscribers and feeds these to the decoder Da via gate Sd opened during the supervisory time position Po. The off hook condition is gated out via Sy also opened at this time and passed to a control circuit E. Register G also feeds comparators Va, Vb which are also fed with coded outputs from Ua, Ub so that if a pulse is present in the Ua or Ub combination identical with that stored in G this pulse is also fed to the control circuit E, which then operates, in manner not shown, in accordance with the indications received. The sequence of operations is thus as follows: a newly calling subscriber provides an off-hook signal, and no pulse is in Ua for this subscriber. The control circuit E on receiving this information allocates the first free channel pulse to the caller and also connects up a digit receiver. When the digits are received the corresponding address is inserted in Ub. When scanning reveals that Ub is on-hook the control circuit arranges (by means not shown) to provide ringing current. When subsequent scanning reveals that the called subscriber is off hook the control circuit causes cessation of ringing current. At the end of the conversation if the called subscriber hangs up first the control circuit takes no action. When the calling subscriber hangs up, absence of on hook signals together with the presence of a pulse in Ua causes the control circuit to delete the pulse from both Ua and Ub. Specifications 981,335, 981,337, 981,338, and 981,339 are referred to.

Filed: 1930-07-10
Abstract: 359,518. Photographic developing apparatus. SOC. FRANCAISE RADIOELECTRIQUE, 79, Boulevard Haussmann, Paris. July 10, 1930, No. 20973. Convention date, July 10, 1929. [Class 98 (ii).] In a printing telegraph receiver, the signals effect printing from a movable stencil on a photographic strip which is developed and dried in a continuously operating tank. The Figure shows the developing tank opened for insertion of a film. For reception of signals the cover 101 is turned counterclockwise through a right-angle about the axis 2. Light reaches the film through a slot 16, and the film is pulled off a drum 3 by pin-wheels 8, is developed, fixed, and washed in tanks 38, and is dried by a strong current of cool air in channel 29 and by a slow current of heated air in channel 31. It is finally wound on a spool 32 after being cut into twelve strips, containing twelve multiplex messages, by rotary knives 33. A pivoted brake 103 is held out of action by the film so long as the latter is taut, but checks over-running of the spool 3 as soon as the tension of the film slackens. A pivoted pointer bearing on the roll indicates on a scale the amount of film in hand. When the film is first inserted, loops of it have to be pushed down into the tanks 38 by means of a poker 35. To permit of this without the pulling back of the film, the pin-wheels 8 are connected to the driving pinions 18 through ratchets 12 integral with the pinwheels and engaging pawls 20 carried by the pinions.

Title: Improvements in or relating to crimped polypropylene filaments
Inventor: BADAMI DWARAKANATH VENKAT
IPC: D01D5/22
Filed: 1960-06-15
Abstract: Crimped polypropylene filaments are made by drawing undrawn or incompletely drawn crystalline polypropylene filaments, having an inherent viscosity from 1-3 and a degree of orientation corresponding to a half peak angle of 6-12 1/2 degrees at a temperature not exceeding 80 DEG C., at a draw ratio of 1,5-5,0 so that the filaments become potentially crimpable, and subsequently relaxing the filaments to crimp them.  Inherent viscosity is defined as five times the logarithm to the base e of the quotient of the viscosity of a 0,2% solution of the polymer in tetralin at 135 DEG C., divided by the viscosity of the tetralin at the same temperature.  The half-peak angle is a measure of the degree of orientation of the fibre and varies inversely therewith. Preferably, the draw ratio lies between 3 and 4.  The relaxation step may be effected by heat-treatment, which may also serve to set the crimp adequately, or, if desired, a subsequent heat-setting step may be applied, comprising heat-treatment, optionally together with water or steam or another swelling agent. Textile articles may be knitted or woven from the crimped filaments.  Potentially crimpable filaments may be made by omission of the relaxation step.  Textile articles may be knitted or woven from such potentially crimpable filaments, and subsequently relaxed to crimp the filaments.  Specifications 527,532 and 810,023 are referred to.
