Title: Method of purifying a cuprous salt catalyst in the synthesis of acrylonitrile
Filed: 1952-12-01
Abstract: <PICT:0716770/IV (b)/1> In the synthesis of acrylonitrile from hydrocyanic acid and acetylene using a cuprous salt catalyst at 70-100 DEG  C., polymerization products dissolved in the hot catalyst are separated by cooling at least part of the catalyst to a temperature below 70 DEG  C. and at which the catalyst is still substantially liquid; the separated polymerization products are removed and the purified catalyst reheated for further use in the synthesis.  Preferably the catalyst is cooled to about 40 DEG  C. and then reheated in two stages, firstly to 50-55 DEG  C. to coagulate the polymerization products, and then to reaction temperature. The whole of the catalyst may be treated at once, or a portion (e.g. one-tenth) may be withdrawn continuously or periodically for purification.  As shown, hydrocyanic acid enters at 1 into reaction vessel R containing a catalyst composed of water, cuprous chloride, ammonium chloride, copper powder, and concentrated hydrochloric acid; acetylene introduced at 2 circulates through pipes 4 and acrylonitrile is dissolved out with water in tower W; a portion of the catalyst passes continuously through pipes 6 to vessel D1 maintained at 40 DEG  C. and then to vessel D2 maintained at 50-55 DEG  C., from which precipitated polymerization products are removed.ALSO:<PICT:0716770/III/1> In the synthesis of acrylonitrile from hydrocyanic acid and acetylene using a cuprous salt catalyst at 70-100 DEG C polymerization products dissolved in the hot catalyst are separated by cooling at least part of the catalyst to a temperature below 70 DEG  C. and at which the catalyst is still substantially liquid; the separated polymerization products are removed and the purified catalyst reheated for further use in the synthesis.

Patent GB-509046-A (GB)
Title: Improvements relating to sound recording apparatus associated with telephone systems
IPC: H04M1/65
Filed: 1937-11-08
Abstract: 509,046. Substation equipment. ALLGEMEINE ELEKTRICITATS - GES. Nov. 8, 1937, No. 30645. Convention date, Nov. 7, 1936. [Class 40 (iv)] In a system for recording incoming messages in the absence of the subscriber, the recording apparatus is connected to the line in response to repeated bursts of ringing current and is put into action by the reception of alternating current impulses dialled by the calling party. As shown, A responds to the ringing current and delivers impulses to D1 which steps round the switch W1. After four steps, B pulls up and bridges the line to operate the ring-trip relay and energize the amplifier V. Relay E pulls up over the line, holds B and completes an interrupted tone circuit over the primary of transformer SU to signal the calling subscriber who then dials a predetermined number (5, as shown). A repeats the impulses to D2 which steps round switch W2. When the predetermined terminal is reached, C pulls up, connects up K, starts the recording apparatus and shunts the interrupter in the tone circuit. When the amplifier warms up, I pulls up in its anode circuit and disables the tone circuit. Relay S which is energized by rectified speech currents and is made very slow to fall back, e.g. by an electrolytic condenser holds open the circuit of the thermal relay H, which would otherwise be made by the thermal relay K after the operation of C, until the message ends. H then energizes F which energizes G and homing circuits are made for switches W1, W2. When both switches are home, all the operated relays fall back. In the case of premature release, H is energized either because W1 stops too soon or because C fails to operate and the switch W1 goes home. If an incorrect digit is dialled, G is energized and is followed by H, F and the switches are sent home.

Title: Method and means for uniformly distributing liquids on rotating surfaces
IPC: B01F3/04
Filed: 1958-09-26
Abstract: 858,691. Moistening gases. PILO, C. W. Sept. 26, 1958 [Sept. 27, 1957], No. 30809/58. Class 55 (2). A liquid medium is uniformly distributed over the rotating surfaces of a rotor so as to establish close contact between the liquid and the gaseous medium in a contact zone of the rotor annularly surrounding a central axis by a process comprising supplying liquid to a sprayproducing means which is situated adjacent to the axis of the rotor and rotates independently about the same axis, as a result of which the liquid is accelerated outwardly from the region of the axis towards the contact zone where the peripheral speed is increased and where the liquid is distributed by the action of centrifugal force on to guiding surfaces, whence the liquid is ejected into the contact zone and is distributed uniformly upon the inner peripheral surface of the rotor as well as parallel to the axis of rotation. As shown in Figs. 1 and 2, rotor 1 (drive shaft not shown) annularly surrounds the sprayer which consists of a plate 2 driven by shaft 3 in direction P; around shaft 3 is pipe 4 through which liquid is supplied to plate 2. On rotation of the sprayer, the liquid passes outwardly on plate 2 to guiding surfaces 5 and 7, the latter being arranged substantially parallel to axis 3. The liquid is distributed uniformly on these surfaces, and is deposited uniformly thereby along the axial length of the contact zone and on the inner peripheral surface of the rotor. Several other embodiments are also described in which the guiding surfaces are perforated, grooved or slotted, or are replaced by pipes 14, 15 (see Fig. 9) having a guiding surface 16 at the end, such pipes opening radially on to the inner peripheral surfaces of the rotor at different levels. It is preferred in all cases that the energy of the liquid droplets striking the rotor be such as may at least in part be the means causing the rotor to rotate.

Abstract: 1303526 Control of AC motors MERLIN GERIN 25 June 1970 [2 July 1969] 30940/70 Heading H2J A door has two panels each driven by a linear induction motor whose field winding components comprise two magnetic elements secured to a beam and disposed on either side of a plate which forms the armature of the motor. The plate is integral with a carriage having rollers for moving the panel. When the door is closed and a detector 74 signals that a person is approaching the door, both field windings 70, 72, are energized through switches A, B, which are actuable in accordance with door-position. After the door has been opened for a given distance, winding 70 is de-energized but winding 72 continues to drive the motor in opposition to the force exerted by an eddy current brake 66. The field windings and the brake are de-energized as the door approaches its fully open position. The closing programme is. similar to the opening programme, and is under the control of doorposition switches D and E. The field energization is reversed if a control signal for opening the door is received during the closing procedure. The winding 70 may serve as a brake by being energized with direct-current or single-phase current.
