IPC: H04B17/40
Filed: 1956-03-20
Abstract: 821,631. Unattended repeater stations. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. March 13, 1957 [March 20, 1956], No. 8693/56. Class 40 (4). In an arrangement for indicating to an attended station the nature of a fault and the station at which it occurs, a fault relay operates a contact, e.g. ra2, Fig. 1, which connects a wire L3 indicating the type of fault to a point on a closed loop L1, L2 comprised in a bridge circuit, which is then balanced manually or automatically by adjusting the slider of the potentiometer S, the position of balance indicating the identity of the unattended station. The balance of the bridge, which is of the Murray type, is unaffected by variations in temperature. Operation of a contact such as ra2 disconnects similar contacts in all succeeding stations and brings up a relay A (in a group A . . . D of such relays) to indicate the nature of the fault F.ig. 2 illustrates the detailed arrangements at the attended station. The operation of one of relays A . . . D brings up X to sound an alarm; and an appropriate one of lamps LA . . . LD is lit. The attendant operates the corresponding one of keys KA . . . KD which opens the circuit of all the other relays to prevent confusion should another fault occur. The switch S whose contacts are interconnected by resistances, not shown, is then set to balance the bridge. This switch may have an additional arm which closes contacts in circuits for lamps identifying the unattended station. The arrangement may be made automatic by causing the operation of any of the relays A . . . D to operate the corresponding contacts KA . . . KD, and also to connect up a stepping magnet for the switch S, the stepping circuit being interrupted by the restoration of a polarized relay connected in place of the galvanometer G. Furthermore, the switch S may be replaced by a stepped ring of gas discharge tubes arranged to short circuit progressively increasing or decreasing resistances. The selected station is then directly indicated by the glow of the appropriate tube. In the case of repeater stations for coaxial cables the wires L1 . . . L6 may be low grade circuits over interstitial conductors.

Title: Improvements in a portable rubbing machine
IPC: A47L11/12
Filed: 1953-03-31
Abstract: 725,848. Compressed air engines; valve gear. CHAMPAYNE, R. J. March 31, 1953, No. 8903/53. Classes 122 (2) and 122 (3). [Also in Group XXIII] The piston 19 of a compressed air engine for a sanding machine (see Group XXIII) is controlled by a distributing valve 31 having a reciprocable spool 32. When the latter is in the position shown, air flows through ducts 34 and 35 to displace the piston 19 to the right, exhaust taking place through ducts 21 and 37. This movement eventually uncovers a duct 23 to permit air to displace the spool 32 to the left and hence reverse the direction of movement of the piston 19 which is of a hollow, light-metal construction. The air expelled by movement of the spool 32 is permitted to pass to exhaust by ports 27, 41 in the piston 19 alternately registering with ducts 25, 26. The axis of the distributing valve 31 is arranged at right angles to that of the piston 19 in the actual construction and the various ducts are drilled in the body of the machine. The piston is reciprocated 3300 times per minute by an air pressure of 80 pounds per square inch.

Title: Novel silicon-containing compositions
IPC: C04B41/49
Filed: 1963-03-07
Abstract: A mixture of 1 to 3 parts by weight of a C1- 6 alkyltrimethoxysilane and 3 to 1 parts by weight of a tetra-methyl- or ethyl-orthosilicate is storage-stable but capable of reacting with water to yield a water-soluble product the solution of which dries to a tough, water-repellent film and may be used to coat porous materials such as wood and concrete. It is also capable of being drawn out of its fibre-glass-like threads. The water-soluble product may also be obtained by first reacting the silane with water and then reacting the reaction product with the orthosilicates. Both reactions are exothermic.  In Examples 1 to 3 10 ml of methyl-, propyl- and butyl-trimethoxysilane respectively are reacted with 10 ml water and 10 ml tetraethylorthosilicate is added to the resultant solution. The product is further diluted with 370 ml water and applied to concrete. In Example 4 a mixture of 10 ml. each of methyltrimethoxysilane and tetraethylorthosilicate is mixed with 20 ml. acidified water (0.005N HCl) and the product diluted with 350 ml. water and applied to paper, wood, bricks and concrete.ALSO:Paper, wood, bricks and concrete are coated with the reaction product of (a) 1-3 parts of a C1-6 alkyltrimethoxy silane, (b) 3-1 parts of a tetra- C1 or 2 alkyl orthosilicate, and (c) water (see Division C3).  The reaction product is water-soluble but dries in the presence or absence of air to a water-repellent coating.  The aqueous solution may be applied by brushing or by spraying using a compressed gas.  In examples the reaction products of equal volumes of water, tetraethylorthosilicate and methyl, propyl or butyl trimethoxysilane are used.

Patent GB-866628-A (GB)
Title: Preparation of collagen films
IPC: A23L13/60
Filed: 1959-03-18
Abstract: Collagen films of uniform thickness are produced by centrifuging a dilute aqueous acid dispersion of collagen fibres, the maximum pH of the dispersion being 5,0, until the dispersing liquid has been substantially removed therefrom, whereby a film is formed, and removing the film from the centrifuge.  The dispersion in the centrifuge may be treated with an alkaline reagent, such as an aqueous solution of ammonium hydroxide, to neutralize the acid during an initial stage in the centrifuging, e.g. by introducing the reagent into the centrifuge prior to the dispersion or by spraying the reagent on to an initially formed film in the centrifuge.  In an example, 250 c.c. of a 0,5% dispersion of collagen in a 0,6% aqueous solution of malonic acid is centrifuged at low r.p.m. in a 4 1/2 -inch diameter basket centrifuge lined with a canvas filter cloth (which has previously been wetted with concentrated ammonia) to form a layer or film of collagen fibres on the cloth.  The film is thereafter sprayed with about 20 c.c. of ammonia and the centrifuge basket then spun for 1 1/2 hours at 2,500 r.p.m. followed by 3,500 r.p.m. for 1/2 hour.  The film thus formed is dried by means of a current of warm air directed into the basket and the clear and transparent dried film, 3 mils thick, is removed from the filter cloth.  The collagen fibres in the film are oriented in one direction (usually parallel to the direction of centrifugal spin) and the film has a higher tensile strength in this direction.  In another example, the film is sprayed with a 2% formaldehyde solution in the centrifuge before being dried.  In a similar manner aqueous solutions of known plasticizers such as glycerol or sorbitol may be sprayed on to the film.  The process of the invention is more rapid than those used in the prior art and the films obtained are of more uniform thickness. The films may be cut into strips, sterilized and used in surgery. They may also be used for wrapping meat products.  U.S.A. Specifications 2,039,145 and 2,598,608 are referred to.ALSO:Collagen film, which may be used for the preparation of surgical sutures or ligatures or formed into tubes for arterial grafts, has uniform thickness and is characterized by orientation of its fibres in a single direction and by a tensile strength greater in this direction than in a direction perpendicular to it.  The film is prepared by centrifuging a dilute aqueous acid suspension of collagen fibres (see Group IV (a).  U.S.A. Specifications 2,039,145 and 2,598,608 are referred to.

Title: Dissolve means for cine cameras
IPC: G03B7/08
Filed: 1973-02-27
Abstract: 1426383 Cinematography AGFA-GEVAERT AG 27 Feb 1973 [28 Feb 1972] 9490/73 Addition to 1396570 Heading G2E A cine camera able to produce fade-out and fade-in includes an arrangement for rapidly assuming a faded-out position when the film drive motor is switched off. To achieve this, a capacitor, which is fully charged or discharged respectively when the camera is set to fade-out or fade-in or vice versa, has the time constant of its charging/discharging circuit altered by the short circuiting of a resistor when the motor is switched off. As shown motor 6 is switched on/off by closing/ opening of switch 10. When switched off, the transistor 26 is switched on to short circuit resistor 25. Thus with the circuit as shown, i.e. the motor 6 is stopped and aperture 17, controlled by galvano meter 16, wide open, switch 24 must be closed to produce the faded-out position rapidly. Thus capacitor 21 discharges through parts 19, 20, 13, 24, 26. When the motor 6 is running the transistor 26 is off and to produce a fade-out discharge occurs through parts 19, 20, 13, 24, 25. The resistor 25 slowing the rate of discharge and hence fade-out.
