Title: Improvements in or relating to selective relays, particularly for electric protective systems
IPC: H02H3/42
Filed: 1927-12-31
Abstract: 282,838. International General Electric Co., Inc., (Assignees of Allgemeine. Elektricitõts-Ges.). Dec. 31, 1926, [Conven- 'tion date]. Cut - out arrangements.-In the protection of a sectionalized line by means of selective time-lag relays would would, normally, isolate a section in a time dependent on the distance between the relay and the fault, relays are chosen which by means of an opposing torque dependent on the current in the line have a constant time of release for faults in all or nearly all parts of the particular section they control and a time which becomes greater for faults outside the section. The time characteristics of relay Ra of two relays Ra, Rb each controlling a section a, b and b, c according to the invention are shown in Fig 3 in which the time action of the relay is constant for all shortcircuits up to a point d short of the end b of its section (to give discriminating action between relays Ra and Rb) and thereafter increases with the distance of the fault in the usual way. Alternatively, the time-lag may be constant for all faults throughout section a, b and then increase suddenly at point b and thereafter become proportional to the distance, as usual. Induction relays.-A construction of relay in accordance with the invention is shown in Fig. 5 in which an induction disc e is subjected to torque by series and voltage windings so designed as to rotate the disc through an angle dependent on the voltage only. This disc carries a contact g which is followed up by a contact h on a second induction disc i driven at a speed dependent on the current. In practice both discs are upon the same spindle The first disc is under the control (in the driving direction only) of a spiral spring f with its inner end resting on a stop o and its outer end connected with a lever k whereby, through a solenoid n and armature l, the control springs can be stressed in accordance with the short-circuit current in the section. Other means may be employed for causing the effect of the curent to operate in opposition to the voltage on the releasing time (as, for example, by opposing the voltage by a voltage across a resistance carrying the current). To obtain a characteristic such as that indicated in Fig. 4, the connection between the spring f and armature l can be released when the fault is located beyond the point b.

Title: Microporous products and method for the preparation thereof
IPC: C08J9/00
Filed: 1977-08-26
Abstract: A three-dimensional, microporous polymer cell structure has a multiplicity of essentially spherical microcells. These have a mean diameter C of 0.5 - 100 microns and are essentially uniformly distributed over the structure. Adjacent cells are connected to one another by pores. The diameter of these pores is smaller than that of the microcells. The pore size distribution corresponds to a sharpness factor S in the range from 1 - 30. The decimal logarithm of the ratio between the mean cell diameter C and the mean pore diameter P has a value in the range from 0.2 - 2.4, and the decimal logarithm of the ratio between the sharpness factor S and the mean cell diameter C has a value in the range from -1.4 to 1.0. The pores and the cells are empty, and the polymer is a synthetic thermoplastic polymer from the class consisting of homopolymers and copolymers of ethylenically unsaturated monomers, condensation polymers and oxidation polymers, or a mixture of synthetic thermoplastic polymers belonging to this class. A further three-dimensional, microporous polymer cell structure corresponds to the above-described polymer cell structure, but at least some of the cells and pores therein are filled with a liquid active ingredient. The liquid active ingredient can be a lubricant, a surfactant, a glidant, a pesticide, a plasticiser, a medicament, a propellant additive, a polish, an insect-protection agent (insecticide), a flameproofing agent, an antioxidant, an antifogging agent or a fragrance.

Title: Improvements in or relating to braking mechanism
IPC: B60T13/16
Filed: 1934-12-13
Abstract: 445,340. Brakes. CLARKE, C. V., 171, Tavistock Street, Bedford. Dec. 13, 1934, No. 35995/33. [Class 103 (i)] An hydraulic brake is operated by manual means which by its initial movement renders operative a servo device which feeds liquid to the system and is rendered inoperative by a valve responsive to the manual and the servo efforts, when these efforts attain a predetermined relative value. Initial movement of pedal 102 operates a rod 105, a lever 109 and a clutch 112 which turns a cam 113 which operates a lever 114 and an hydraulic cylinder 106 which supplies liquid through a pipe 129 and past a check valve 126 and a piston 107 to the brake lines 135. Lever 109 reacts on a piston 119 which bears on liquid trapped in a. chamber 120. When the pressure of fluid passing valve 126 and acting on a piston 123 is greater than the pressure acting on the piston 119, valve 121 is opened and releases liquid from the chamber 120 back to the tank 116 and allows the lever 109 to move clockwise and release the clutch 112. Manual effort to the brakes through the pipe 135 is applied through the pedal 102 and the piston 107. On brake release a valve 138 is released by a rod 141and a lever 103 on which pedal 102 is pivoted, in order to allow liquid to return from the brakes to the tank 116 via a port 136 uncovered by a piston 107 in release position. The valve 138 is closed by initial movement of the brake pedal. In a modification, part 136 is replaced by a valve in the pipe 135 operated by a cam on the rod 105. Also a spring piston in tank 116 is reacted on by the liquid in pipe 129 and when the pressure falls in this pipe due to forward movement of the piston 107, the spring piston moves forward to compensate for this movement. In a further modification, the clutch 112 comprises external shoes acting on a drum, the ends of which overlap and are operated by an hydraulic cylinder. The shoes are mounted on a plate rotatable about the axis of the drum and carrying rollers acting on cam faces on two levers, one connected to the piston and the other to the cylinder of the piston and cylinder 115.

Abstract: 1359683 Phenol-formaldehyde resins; foams PILKINGTON BROS Ltd and S P RILEY 12 July 1972 [30 July 1971] 36015/71 Headings C3R and C3C A phenol-formaldehyde resin comprises the product of reacting a sulphonated novolac resin, which has been condensed from at least one phenol and formaldehyde and subsequently sulphonated so as to contain sulphonic acid groups, with a resole resin. Some sulphonic acid groups of the novolac may have been neutralized to give a sulphonate metal salt, or reacted with an organic base. The condensation of the novolac may be effected using 1 mole phenol(s) and 0À3-1 mole HCHO in acid conditions, preferably in the presence of an organic acid, such as oxalic acid. The sulphonation is preferably carried out using 0À1-1À5 moles H 2 SO 4  per mole of phenol(s) used to form the novolac, and the viscosity of the sulphonation product is preferably adjusted by dilution with water to less than 100 poises at 20 C. before reaction with the resole. The condensation of the resole may be effected using 1-3 moles HCHO per mole of phenol(s) in the presence of an alkaline catalyst. The sulphonated novolac and the resole may be reacted in molar proportions of 100 : 1 to 1 : 100. A cross-linking agent such as hexamethylenetetramine may be added. A solid foam may be produced by reacting the sulphonated novolac with the resole in the presence of a surfactant such as a silicone oil or a polyoxyethylene sorbitan monopalmitate, and a foaming agent such as a low boiling aliphatic hydrocarbon or a halogenated derivative thereof, e.g. CCl 4 , CCl 3 F, CFCl 2 .CF 2 Cl, n-pentane and hexane. The exothermic heat of reaction is used to activate the foaming agent. Many examples of phenol-formaldehyde foams are given. Uses.-Fire-resistant insulating materials.

The container is formed from a blank strip S, Fig. 4, in which a cut line 16 is made to extend to one end of a transverse cut 23. A further cut 24 extends from the other end of the cut 23 to a point 26 short of the end of the strip, the remaining part 27 of the material subsequently forming a hinge for the cover C. The strip S is coated with adhesive on its outward face and wound on a mandrel to unite the plies 18, 19, 22 and 25, a tape 29 of "Cellophane" (Registered Trade Mark) being incorporated, thereby masking the adhesive in its area. The tape 29 therefore forms a strip joint consisting of the flange 30 on the body portion B and recess 31 in the cover C. An overlap 28 is provided in the end portion of the strip. After winding on the plies, a label ply 11 is adhered to the container overlying a pull string 13 aligned with the cut line 24 and the hinge 27.
