Patent GB-2012263-A (GB)
Title: Aldehyde adducts
IPC: C07C317/18
Filed: 1978-12-20
Abstract: Stable adducts of glutaraldehyde or oxydiacetaldehyde with 1,4-butane- disulphinic acid are disclosed. These adducts may be prepared by reacting the dialdehyde with the butane- disulphinic acid in a suitable solvent, generally water, and generally in a molar ratio of from 2:1 to 1:2. The adducts decompose on addition to an alkaline aqueous solution to liberate free dialdehyde and may thus be employed in the production of sterilizing solutions containing the aldehyde as sterilizing agent. The adducts may be put up in the form of compositions also containing an alkaline reagent, such as sodium bicarbonate, which composition on addition to water will give a free aldehyde containing solution.

Title: Line current feed and hybrid arrangement (system X)
IPC: H04B1/58
Filed: 1978-12-30
Abstract: In a 2/4 wire converter the 2 wire line is isolated from the electronic circuits by means of a transformer T, which also performs the function of a hybrid circuit. The 2 wire terminating impedance Zt also serves as the line current feed. In order to avoid shunting this impedance by the amplifiers A1 and A2, it is necessary to make the input impedance of A1 and the output impedance of A2 relatively high. A conventional way of achieving a high output impedance for A2 is to arrange the internal feedback circuits to give a current output rather than the more usual voltage output. <IMAGE>

Title: Techniques for measuring the braking efficiency of industrial machines
IPC: G01M99/00
Filed: 1979-04-11
Abstract: Safety regulations prescribe that the braking systems of certain industrial machines should halt the moving parts of such machines within a prescribed time or distance. To test such braking systems, e.g. on guillotines or presses, it is necessary to initiate the braking operation at an instant when the moving part is travelling at its maximum velocity, typically when the moving member is approximately mid-way through its stroke. The invention provides an actuator 32 affixed, e.g. by magnet 33, to a chosen position on the moving member. The actuator 33 co-operates with a sensor 35 adjustably mounted on the of the machine bed. When the moving member reaches a desired position along its stroke, it causes the sensor 35 to produce a signal which commences a braking operation and also initiates a timing operation which is ended, by a device 21-30 arranged to sense when the member comes to a halt. <IMAGE>

Patent GB-2077111-A (GB)
Title: Nasal Tamponade
IPC: A61M31/00
Filed: 1980-06-05
Abstract: Known nasal tamponades which incorporate an inflatable bag suffer from the disadvantage that they cause a high pressure to be transmitted to relatively small areas of the nose defining the nasal cavity and the post-nasal space. The nasal tamponade of the present invention permits a low pressure to be transmitted over a large percentage of the surface regions defining the nasal cavity and post-nasal space, thereby reducing the likelihood of any damage to tissue, and comprises a single inflatable bag 5 which when inflated, even outside a nasal cavity and an associated post- nasal space, generally conforms to the shape of the combination of a nasal cavity and an associated post- nasal space, the bag 5 being formed of a medically acceptable flexible material readily capable, when inflated in the nasal cavity and post-nasal space, of generally conforming to said shape whilst accommodating any irregularities in the surface regions defining the nasal cavity and post-nasal space, so that a major portion of the external surface of the bag 5 may abut the internal surface regions defining the nasal cavity and post-nasal space; and a tube 1 which whilst being flexible is less flexible than the material of the bag 5 and which extends through the bag 5, the tube 1 being provided with one or more port 6 opening into the bag 5 so that on introduction of a gas along the tube 1 the bag 5 becomes inflated, and the tube 1 being suitable to assist in introducing the bag 5 when deflated into the nasal cavity and post-nasal space. <IMAGE>

The valve (B) remote from the connection to the system (the suction connection (10) in the positive pressure- generating pump in the Figure) is associated with a bypass (16) which inter-connects opposite sides of the valve during starting. The bypass (16) remains open, at least intermittently, during the normal closing times of the valve but is closed during the closing times of the valve (13) when the operating speed range of the pump is reached. The valve (13) is in the form of a flexible tongue (22) and the bypass (16) is provided by the stepping back of the valve seat (17) from the plane containing the sealing surface of the tongue when the latter is in its non- deflected position shown. <IMAGE>
Patent GB-811036-A (GB)
Abstract: 811,036. Gyroscopic apparatus. HOLLANDSE SIGNAALAPPARATEN, N.V. May 17, 1956, No. 15405/56. Addition to 755,326. Class 97(3) The control element for a gyroscope erecting mechanism consists of a tube rotatable with the gyroscope about the axis of control in which either a gas bubble or evacuated space in a damping liquid, or a liquid drop in a damping liquid or gas, is displaceable to open and close controlling circuits for erecting meins such as a torque motor, and in which the drop, bubble or space completely or nearly completely fills the cross-section of the tube, and movement of the damping fluid is made possible by a damping channel connecting the spaces on opposite sides of the drop, bubble or space. As shown in Fig. 1, a tube 102 has a slight but sharp upward bend in the middle and is filled with a conductive liquid 103 except for a space occupied by a gas bubble 113 which fills the cross-section of the tube. Movement of the bubble causes movement of the liquid through a narrow channel 111 connecting opposite ends of tube 102. Contacts 101, 109 at the ends of the tube are connected to one side 112 of an electric supply, while contacts 104, 108 are connected via relay coils 105, 107 to the other side 106 of the supply. When the bubble is in its central position, it insulates contacts 104, 108 from contacts 101, 109; but on movement of the bubble a circuit is completed either through contacts 101, 104 and relay coil 105 or through contacts 109, 108 and relay coil 107. The relay which is energized operates erection means to restore the gyroscope, and with it the tube, to the position where the circuit is broken. The separate channel 111 may be replaced by a groove in the side wall of the tube; surface tension keeps the bubble out of the groove. Further modifications are described in which the damping liquid and bubble are replaced by other liquids or gases of different specific gravities and electrical conductivities, the contacts are differently arranged, the tube is bent downwardly instead of upwardly, or is straight, and in which a number of contacts disposed along the tube are bridged by resistances. The movement of the bubble, drop or space may be sensed by photo-electric means instead of by means of electric contacts.
