Title: Improvements in or relating to the manufacture of regenerated cellulose sheets, films, filaments, threads and the like produced from viscose
IPC: D01F11/02
Filed: 1944-04-20
Abstract: In the manufacture of regenerated cellulose sheets, films, threads, filaments and the like by the viscose process, the freshly-formed materials are treated, subsequent to desulphurising treatment and prior to a bleaching treatment, with a hot dilute aqueous solution containing a non-oxidising mineral acid, in a proportion of between 0.05 per cent and 1.0 per cent by weight, based on the weight of the solution, the sulphide sulphur content of the finished materials being thereby substantially eliminated. The preferred non-oxidising acid is sulphuric acid, but other mineral acids, e.g. hydrochloric or phosphoric acids, may be employed.  The dilute aqueous solution of the acid is employed at a temperature of 80-100 DEG  C.  The preferred desulphurising agent is sodium sulphide in aqueous solution, the temperature of which is preferably 90 DEG  C., but other known agents such as the sulphides of potassium, ammonium, or an alkaline earth metal or the sulphites or thiosulphates of sodium or potassium may also be used.  For bleaching, a dilute aqueous solution of sodium hypochlorite is preferred although dilute aqueous solutions of other alkali metal or alkaline earth metal hypochlorites, or aqueous solutions of hydrogen peroxide, alkali metal perborates, percarbonates or chlorites may be employed. Examples are given, in one of which a regenerated cellulose film cast from viscose is washed with water, passed through a desulphurising bath comprising an aqueous solution of sodium sulphide at a temperature of 90 DEG  C., washed with a counterflow of water at 90 DEG  C., and passed through a 0.2 per cent aqueous solution of sulphuric acid at a temperature of 90 DEG  C.  The film is removed, washed with water at 35 DEG  C., bleached by passage through an aqueous sodium hypochlorite solution, washed, impregnated with glycerine and dried.

Patent GB-713489-A (GB)
Title: Production of acetals of acetylacetaldehyde
Filed: 1952-03-24
Abstract: Dialkyl acetals of acetylacetaldehyde are obtained by hydrolysing the addition products of three to four moles of a lower alkanol, having no more than four carbon atoms, to one mole of diacetylene.  The hydrolysis may be carried out with water, preferably at about room temperature and proceeds more quickly if the water is acidified, e.g. with acetic or sulphuric acid.  The desired acetal may be recovered from the reaction mixture by fractional distillation or by the addition of agents capable of salting out the compound but if the hydrolysis is carried out in an acid medium it is necessary to neutralize the solution mixture before recovery.  In examples: (1) a mixture of b -methoxycrotonaldehyde dimethyl acetal and acetylacetaldehyde tetramethylacetal (obtainable by the addition of three to four moles of methanol to one mole of diacetylene) is stirred with water at room temperature and the solution distilled in vacuo to yield acetyl-acetaldehyde dimethyl acetal; (2) and (3) as in (1) except that the hydrolysis is carried out with water acidified with acetic and sulphuric acid respectively, the hydrolysis mixture in (2) being treated with potassium carbonate and that of (3) with barium carbonate prior to the final distillation in vacuo.

Filed: 1928-03-16
Abstract: 302,267. Siemens & Halske Akt.- Ges. Dec. 13, 1927, [Convention date]. Semi-automatic exchange systems.-In a callfinder system, if all the finders of a group are busy when a call is initiated, the calling impulse is stored so that independently of the calling subscriber the call will be extended as soon as a finder becomes free. In the system shown, calls from a subscriber Tln at a small office, Fig. 1, are extended over tandem call-fingers, AS1, AS2, to a junction. VLa, VLb, leading to a second small office from which they are further extended over similar tandem finders and a junction VLa1, VLb1, to a manual position at a main exchange Fig. 3. A call is initiated by operating the magnets J and the calling party only removes his receiver when his bell is rung by ringing-current sent back by the operator when the call reaches her. First call-finder AS1. Alternating current from the magnets J energizes winding I of relay T which partially operates to close contact 1t, thus completing a locking circuit over winding III in series with relay An. Contact 3t connects winding II to the test terminal. Relay An energizes relay R in the first idle finder so that the finder rotates until the calling line is found, when relays C, P, operate in series with winding II of relay T. The latter now operates its remaining contacts, cutting off relay An and switching through. If no finder is available when the call is initiated, the circuit over relay An and winding III of relay T remains closed until one becomes free. Second call-finder AS2. Relay C energizes relay R1 which causes an idle second finder AS2 to hunt, and when the calling link is found relays N, PI operate in series, the former removing a short-circuit from its upper winding and transmitting an earth impulse over conductor VLa to operate a relay in the second office which locks up in exactly the same manner as the relay T. Relay N also energizes relay M which in turn operates relay G, thus switching through the awire. Completion of connection. The tandem finders in the second exchange operate in the same manner as finders AS1, AS2, and an earth impulse is sent over junction conductor VLa1 to operate relay E, Fig. 3, which locks up and lights lamp AL. When the operator pluga in, relay D operates over the sleeve circuit, and relay K and a similar relay in the second exchange operate in parallel over the a-wire. Relay H is energized by relay K. The operator sends back ringing- current to the calling subscriber, who thereupon removes his receiver, and the connection is completed by the operator in known manner. Release. At the end of conversation, the subscriber Tln operate his magneto J energizing relay S, Fig. 3, which lights lamp SL. When the plug is removed, relay K releases and prior to the relapse of sluggish relay H, relay V operates unlocking relays T, P and releasing relay C which in turn unlocks relays N, P1.

Title: Improvements in couplings for pipes
IPC: F16L23/04
Filed: 1961-03-06
Abstract: 910,572. Pipe couplings. AEROQUIP A.G. March 6, 1961 [April 21, 1960], No. 8137/61. Class 99(1). A device, for example remotely operated, for coupling the opposed outwardly flange ends of a pair of axially aligned pipes 88, 90 comprises a housing 10 having an opening 18 therethrough and a radially extending wall 13 annularly disposed about the opening, a ring member 32 rotatably mounted in the housing and having an opening therethrough axially aligned with the opening 18 and a radially extending wall 42 annularly disposed about the ring opening, a number of circularly arranged cam slots 64, 58 extending through the walls 13, 42 respectively and a number of bearing members 70 each extending through one of the housing cam slots and one of the ring cam slots. There are a number of gripping segments 72 mounted in the housing on the respective bearing members and which are radially movable between innermost positions in which they are engaged over the pipe flanges to couple the pipes together and outermost positions in which they are disengaged from the flanges. Drive means engaged with the housing and the ring impart relative rotation between the housing and ring so as to cam the bearing members in the cam slots and thereby radially move the gripping segments. As shown, the housing carries a worm 52 which engages gear teeth 34 on the ring member 32, and a pin 98 secured to the pipe 88 passes through a cam slot 100 in a sleeve 48 of the ring 32 and an axial slot 102 in a sleeve 22 of the housing. The segments 72 are biased radially outwardly by an expandible circular spring 84. In operation, the pipes are disconnected by rotating the worm 52 so as to rotate the ring 32 anti-clockwise within the housing thereby causing the rods 70 to ride radially outwardly in the slots 64, 58 thus moving the segments out of engagement with the pipe flanges. During the initial movement of the segments, the pin 98 is engaged in a circumferential portion of the cam slot 100, so that rotation of the sleeve 48 will not cause axial movement of the pin. When the segments are clear of the flanges the sleeve 48 has rotated sufficiently to enable the pin 98 to reach an axially inclined portion of the slot 100 further rotation of the ring 32 drives the pin forwardly into the portion 106 and the pipe 88 moves axially forwardly through the housing to force the pipe 90 completely out of the housing. Specification 856,494 is referred to.
