Title: Process for preparing a wound covering
IPC: C08L89/00
Filed: 1966-06-17
Abstract: 1,147,072. Collagen films; collagen laminates. B. BRAUN INTERNATIONAL G.m.b.H. 17 June, 1966 [9 July, 1965], No. 27224/66. Headings B5B and B5N. [Also in Divisions A5 and C3] In the manufacture of a "wound covering" which resembles natural human skin and which is intended for use as a substitute for skin in transplant skin surgery, a collagen-containing film is prepared by foaming a sol which has been prepared from animal collagen or a collagen derivative and which contains more than 9%, preferably more than 10%, by weight of plasticizer calculated on the "total sol component", converting the sol into a gel containing a proportion of water higher than that normally present in human skin, cutting film from the gel, and tanning the film. (The normal water content of human skin is stated to be from 60% to 75% by weight.) In order to impart elasticity thereto, elastin may be incorporated in the tanned gel film, an elastin sol being added to the collagen sol prior to foaming in an amount advantageously of 20% by weight calculated on the collagen sol. The term "total sol component" is defined as the amount of collagen sol (in the absence of elastin sol) or the combined amounts of collagen sol and elastin sol. The plasticizer may be a polyol, for example glycerol. Foaming of the sol preferably is carried by the injection of fine bubbles of air or of other gas inert to the sol and to physiological tissue. Tanning is carried out with a physiologically acceptable tanning agent which may be either a vegetable product, for example tannin, or a synthetic product, for example a polyaldehyde such as glutaric dialdehyde. To provide the wound covering, the tanned gel film is adhered, for example by an adhesive based on a cyanoacrylate compound, to a cover film which preferably is manufactured from the same material as the gel film; the elastin content of the cover film however may be greater than the elastin content of the gel film. The cover film may be prepared in a manner similar to the preparation of the gel film (but without foaming and, if desired, without tanning) and thereafter is dried. In order to provide further strength and to prevent drying of the gel film, a film of a plastics material, for example polyvinyl chloride, may be cemented to the free surface of the cover film; this plastics film may be larger than the laminate of gel film and cover film to enable the wound covering to be attached to a patient by for example an acrylic adhesive.

Abstract: 378,686. Wireless signalling. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Oct. 1, 1931, No. 27361. Convention date, Oct. 2, 1930. [Class 40 (v).] In a system for selectively transmitting two signals one comprises a modulated carrier, the other being the unmodulated carrier. The valve 3 which feeds a line through condensers 7 has its grid circuit energized either by the carrier frequency generator 4, through key 5, or by the generator 4 and modulation frequency generator 9 in combination, through key 8. At the receiver the low-frequency circuit has a relay 12, and a relay 15 fed through a transformer 13 and rectifier 14. Only direct current flows in the low-frequency circuit when the unmodulated carrier is being received and the relay 12 responds to close circuit I at contact 12a. When a modulated current is being received the low-frequency circuit carries a D.C. and an A.C. component, the latter energizing relay 15 to close circuit 11 at contact 15a and to open circuit I at contact 15r to prevent operation of circuit I by the D.C. component through rela.y 12.

Farbenindustrie Akt.-Ges. , Frankforton-Main, Germany) Sept. 24, 1934, No. 27367. [Class 98 (ii)] In producing the film on stock having sensitive layers on both sides, differently coloured by dyestuffs transparent to infra-red, the component pictures being produced by local destruction of dye-stuff, as described for example in Specification 412,949, the layer or layers most transparent to infra-red are arranged on one side and the sound record is copied thereon, the sound strip of the layer or layers on the other side being exposed to uniform illumination so that in the subsequent treatment to produce the dye pictures the dyestuff therein will be destroyed, whereas it is prevented from being destroyed in the layer or layers containing the sound record as by the application of a varnish resist layer. In an example, a film is used bearing on one side a red-sensitive emulsion C dyed with Sirius Yellow, overcoated with an ordinary emulsion B dyed purple-red with Sirius Ruby, and on the other side a green-sensitive emulsion layer D dyed blue-green with Brilliant Benzo Fast Green BL. The picture components are printed respectively in the three layers, but the sound track F is copied in the layers B, C only. The sound strip on the other layer D is uniformly exposed, and the dyestuff is destroyed therein in the subsequent processing, whereas such destruction is prevented as above described in the strips B, C containing the sound track F.

In a gyratory vibrator the rotor body rotates about its axis under a magnetic field produced by the stator and rolls on circular tracks concentric with the stator so as to gyrate, without tilting, about the stator axis, In one form, Fig. 2, the laminated squirrel cage rotor 2 is revolved about its own axis by a rotary field produced by the stator 1 and gyrates about shaft ends 4 extending partly or completely through a central bore 3. The rotor periphery carries annular discs 6 running in grooves 7 to prevent tilting. In a modification, the rotor body has no central bore and carries projecting toothed wheels which roll round in recesses in the end-shields. In a further modification, Fig. 5, two axially disposed stators 10, 11 produce an axial rotating flux which passes through the rotor, the spirally laminated cores of the stator and rotor carrying respectively windings 12, 13 and a squirrel cage 16. The rotor rolls on conical surfaces 20, 21 and a casing 23, 24 enables the vibrator to be used for immersion in liquids. In modifications, only one stator core may be used and the rotor may gyrate about a central bolt.

Title: Expression controlling device for pneumatically-operated musical instruments
Filed: 1922-10-12
Abstract: 212,596. Martts, E. C. R., (Standard Pneumatic Action Co.). Oct. 12, 1922. Expression-controlling; winding-mechanism.- Means for controlling the air-tension, to control expression, comprise an automatic governor and a valve giving ungoverned tension, which are brought into operation alternatively by manual means also controlling a throttle valve which is independent of the governor. The construction enables the expression to be controlled whether the music sheet is cut for accenting or not. In the position of the valves shown in Fig. 3 and with a tune-sheet not cut for accent, the instrument plays loudly, air of ungoverned tension passing from the action connected at C, through chamber 13, port 14, chamber 15, port 16, chamber 17, port 18, chamber 19, and port 20 to exhaust. To soften, say, the bass, the top of the left-hand lever 40, Fig. 1, is moved to the right, moving a link 37, 36, which allows a valve 51 to close and also moves a slide-valve 26 partially or wholly over a tapered slot over a port 21. The closure of the valve 51 cuts off atmosphere from a tube 48 leading to the diaphragm 45 of a primary valve 42 thereby putting the valve-chamber 43, which is connected to the underside of a diaphragm 23, to atmosphere, so that the suction closes the port 14. The tube 48 also has a branch 53 connecting with the underside of diaphragm 22 which is therefore cut off from atmosphere by the closure of the valve 51, and falls. When the valve 26 is entirely closed, the air passes only through passage 28, automatic governor 29, port 34, and chambers 15, 17, 19, and the playing is softest; but the valve 26 may be partly opened to give an adjustable throttled tension, air then passing through the port 21 and chambers 15, 17, 19. The levers 40 may be simultaneously moved in the same or opposite directions, but are connected by a spring 41 which normally sets the construction for ungoverned tension. With a tune-sheet cut for accenting the levers 40 are arranged to give the tension required for the accompaniment, the valve 42 being in its upper position and the valve 23 being closed. An accent perforation admits air by a tube 46 to the diaphragm of the valve 42, thereby opening valve 23 and permitting ungoverned air to pass. The re-winding lever 58, Fig. 1, when operated moves a pivoted valve 55 to admit atmosphere to tubes 56 which lead respectively under diaphragms 24 in each valveunit, and the ports 18 are therefore closed to cut off the valve units and actions during re-winding.
