Title: Improvements in and relating to the manufacture of artificial structures and other useful articles from cellulose derivatives
IPC: D01F2/28
Filed: 1935-11-15
Abstract: For the working-up of alkali soluble cellulose ethers in the manufacture of artificial silk, &c., films, plates, plastic masses, adhesives, cements, finishes, coatings, &c., there is employed as the coagulant for the cellulose ether solution, particularly the liquid solution, or to assist in such coagulation, a medium containing an alkali metal secondary carbonate, in particular sodium carbonate. The shaped structure such as a thread may be introduced directly into the medium, or it may be preliminarily coagulated in a neutral or alkaline bath. The alkali carbonate coagulant may also contain an inorganic or organic neutral salt and another alkali metal salt of alkaline reaction, and also glycerine, glucose, turkey red oil etc.; it may be used at temperatures above 40 DEG C., and the caustic alkali introduced during the coagulation may be neutralized by passing carbon dioxide into the bath. After treatment with the alkali carbonate, the product may be washed with water or may be treated with an acid, neutral or alkaline bath. The cellulose ethers employed may contain less than one ether group per 1--2 C6H10O5 units, and the ether groups may be alkyl, hydroxyalkyl or alkyl hydroxyalkyl. In examples illustrating the manufacture of threads, films, cements, adhesives and plates and the finishing and printing of textiles there are described suitable processes for the manufacture of the cellulose ethers, and also methods for working up their, solutions these being used as primary coagulation baths solutions of sodium carbonate of 10--36 per cent, and of sodium carbonate baths containing sodium sulphate, glucose, glycerine, borax, sodium sulphite, sodium bicarbonate, and caustic soda, such baths being at temperatures of 20--90 DEG C., or there are used primary coagulation baths of sodium sulphate, ammonium sulphate or ammonium chloride followed by an alkali carbonate bath as stated above.  Baths of sodium bicarbonate at temperatures above 50 DEG  C. may also be used.

Patent GB-421407-A (GB)
Title: Improvements in the manufacture and production of aliphatic diaminocarboxylic acid derivatives
IPC: C07C273/18
Filed: 1933-05-20
Abstract: Aliphatic a o -diaminocarboxylic acids, whose a -amino groups are protected by such substituents as acyl groups, are condensed with aliphatic urethanes in the absence of water, and if desired, the protecting substituents then removed by saponification.  The products possess therapeutic properties.  The condensation may be effected in the presence of acid-reacting salts of bi- and tri-valent metals, e.g. the chlorides of zinc, iron or aluminium. According to the examples, (1) d -carbamidoornithin (citrullin) is prepared by heating a -monobenzoyl-ornithin and saponifying with dilute sulphuric acid the resulting a -monobenzoyl - d  - carbamido - ornithin; (2) o  - carbamido-lysine results from the condensation of a  - monobenzoyl - lysine (a  - monobenzoyl - a e -diamino-capronic acid) with acetylurethane, followed by saponification of the a -monobenzoyl-o -acetylcarbamido-lysine so obtained.  In the same way, a o -diaminobutyric and a o -diaminocaproic acids may be converted into their carbamido compounds.  Aliphatic a -acylamino-o -aminocarboxylic acids are prepared by acylating a o -diaminocarboxylic acids and treating the diacylamino products with weak alkalies such as baryta water.  The starting materials in the above examples are obtained in this way.

Title: Sensitive pulse threshold detector
IPC: H04L25/03
Filed: 1974-04-03
Abstract: 1457635 Stabilizing the threshold of switching circuits HUGHES AIRCRAFT CO 3 April 1974 [16 April 1973] 14839/74 Heading H3T A hysteresis or non-hysteresis thresholding circuit has a setting phase in which feedback provides an input bias which sets the output at a desired level and an active phase in which the feedback path is interrupted but the bias maintained and in which a steady or varying backing-off bias is supplied to the input so that the output crosses the desired level only if the input signal exceeds the backing off bias. Offset errors in the circuit are thus avoided. In Fig. 3 an operational amplifier threshold circuit is set to a given level during the setting period, when the input signal at 72 is zero, by a gate-and-hold feedback circuit 86, C2. During the active phase a gating pulse is applied at 68 to make gate 36 non-conducting so that the bias from C2 is maintained. In addition the gating pulse switches on a transistor Q3 so that a back-off bias is applied to the amplifier via a resistor R16. If a signal at terminal 72 is in excess of the backing-off bias the amplifier switches its output state, possibly to saturation. In Fig. 5, the operational amplifier is arranged to operate as a Schmitt trigger. The input quiescent-bias is controlled to be maintained at one of the switching levels so that active phase, i.e. in the presence of a pulse at 68, the circuit switches if the signal at 72 exceeds a back-off bias from 70. During the setting phase, i.e. in the absence of a pulse at 68, the back-off bias is removed and the input signal is also zero. If the quiescent bias from an integrator 38 is too high the circuit triggers and a first monostable circuit 34, followed by a second monostable circuit trigger and as a gate 36 is opened by pulse 68, an increment of charge is placed in the integrator 38. The first monostable circuit momentarily operates to restore the trigger. If the circuit again triggers the cycle repeats until the quiescent bias reaches such a level that circuit remains untriggered. During this condition the integrator slowly discharges until the circuit triggers again and the cycle repeats repeat. Thus the bias oscillates in a very narrow region around the untriggered threshold.

Filed: 1924-06-20
Abstract: 237,071. Bjerregaard, J. J. June 20, 1924. Tool-arm mountings.-In a sound-box for gramophones or like sound-recording or reproducing apparatus, the cross arm of the stylus bar is mounted on the sound-box casing by means in which convex or like inclined surfaces are so engaged by sharp edges formed on the cross arm as to provide two parallel axes of oscillation, and the arrangement is such that the plane bisecting the angle at each bearing edge meets the surface on which the edge rests approximately at right-angles. Figs. 1 and 3 show a construction in which the cross arm 5 is supported on cylindrical members 9, which rest on the edges of a groove 3 in the sound-box, and are engaged by the edges of rectangular holes 8 in the cross arm. Springs 11 surrounding screws 10, which pass through the arm 5, bear against the arm. Two unequal cylinders, or one long cylinder, may be employed instead of the parts 9; or balls may be used as the bearing members. Figs. 6 and 8 show modifications in which truncated conical surfaces support the cross-arm 5, the single cones 17, Fig. 6, being fixed to the casing 2, and the double cones 18, Fig. 8, engaging slightly oval holes 19, 20 in the parts 2, 5 respectively. Figs. 10 and 11 show a further modification in which the arm 5 is supported between pairs of cylinders 21. Pyramids or prisms may be used instead of the cones and cylinders in the various . constructions shown. The bearing edges may, instead of being continuous, be formed as serrations, or may be replaced by points. The cylinders, cones, &c. are made of hardened steel, glass, or the like.

Title: Seal for rotating machinery
IPC: F04D29/16
Filed: 1957-05-10
Abstract: 813,958. Elastic-fluid turbines; stuffing-box substitutes. GARRETT CORPORATION. May 10, 1957 [May 16, 1956], No. 14965/57. Classes 110 (3) and 122 (5). A seal between the stator 10, Fig. 1, and rotor 18 of a turbine or other rotary machine comprises an axially-movable and floating sealing ring 42 which is carried by the stator so as with the rotor to separate two spaces 100, 106 subjected to different pressures and provided with two annular sealing ribs 52, 54 on the face presented to the rotor and passages 56 connecting the space 102 between the ribs with a rear chamber 104 enclosing the rear face of the ring, the arrangement being such that the balance of pressure on the two faces of the ring maintains the desired clearance between the ring and rotor. The ring is mounted in an annular opening 40 formed in the stator 10 by two wall sections 38, 12 connected by an annular cover 58 to form the chamber 104. In operation, high pressure fluid, which is admitted to the turbine rotor 18 through a nozzle ring 22, escapes through the clearance space 30, 28 between the nozzle ring and rotor into the space 100 where it acts upon the surface 41 of the ring 42 to increase the gap between the rib 52 and rotor surface 34. The fluid in the space 102 then passes both through the passages 56 to the chamber 104 to act upon the rear side of the ring to return it to its normal position and through the clearance between the rib 54 and surface 34 into the low-pressure space 106 where it may then escape to atmosphere through vents 98. By suitably positioning the ribs on the ring the pressure in the chamber 104 may be arranged to balance the pressure acting upon the ring in the spaces 100, 102, 106 thereby maintaining the desired clearance. The ribs 52, 54 may engage a frusto-conical section on the rotor surface, and the clearance between the two ribs and the rotor surface may be equal or unequal. Bosses 70 on the ring co-operate with mating bosses 68 on the stator to prevent rotation and to limit the extreme axial movement of the ring. Piston rings 44, 48 may be provided to seal the outer and inner peripheries of the ring 42 and have in their operative faces a circumferential groove 80, Fig. 2, and axial grooves 82 which reduce the surface area in order to permit free movement of the ring and communicate with the higher pressure spaces. If desired, one or other of the piston rings may be designed to allow a slight leakage or, alternatively, a bypass may be arranged through the ring 42 from the chamber 104 to the space 106. The balance of pressure effect may also be used to balance the end thrust of the rotor.
