IPC: C07D205/09
Filed: 1980-04-11
Abstract: 2-[(2-Aminoethyl)thio]-6-(1- hydroxyethyl)penem-3-carboxylic acid, its salts and esters are valuable antibiotics effective against a wide range of Gram-positive and Gram- negative bacteria, even including bacteria of the genus Pseudomonas. These compounds may be prepared by the heat-induced cyclization of a phosphorus-ylide compound followed, if necessary, by removal of protecting groups and salification or esterification. The compounds exist as a variety of stereoisomers, of which (5R, 6S)-2-[(2-aminoethyl)thio]-6- [(R)-1-hydroxyethyl]penem-3- carboxylic acid and its salts and esters are preferred.

Patent GB-2066850-A (GB)
Title: Annealing Steels
IPC: C21D1/26
Filed: 1980-11-07
Abstract: A process for the annealing of hypoeutectoid steels wherein a steel is rapidly heated e.g. by electrical resistance means, to a temperature above the upper tranformation temperature of the steel to convert the steel to austenite and carbides, followed by cooling of the steel. The rate of heating of the steel is such as to cause dissolution of most of the carbides in the austenite thus formed, thereby leaving small particles of undissolved carbide in an amount sufficient to serve as nuclei for the precipitation of upper transformation products on cooling. Steels processed in accordance with the process of this invention are characterized by improved ductility and toughness as well as good machinability characteristics. <IMAGE>

Patent GB-2059444-A (GB)
Title: Surface hardening of metals by electric arc discharge
IPC: C21D9/04
Filed: 1980-05-06
Abstract: Alloys which respond to heat treatment are surface hardened by establishing an electric arc between a non-consumable electrode and the metal surface and causing relative movement between the arc and metal surface to occur so that the surface temperature is raised to the austenitic range but below the melting point. Removal of the arc causes the surface to cool rapidly and brings about transformation hardening. The procedure may be applied to steels, cast irons and certain non-ferrous metal alloys which are susceptible to transformation hardening. Practical applications include the surface hardening of railway track, railway wheels and crankshafts as well as the cylinder walls and valve seats of internal combustion engines.

Title: Telephone debit card
Inventor: SOTHCOTT PETER
IPC: G06K19/067
Filed: 1981-07-07
Abstract: A known debit card bears an electrical resistor of tapered form such that it heats up progressively along its length as a current flows in it. The resistor is overlaid by a thermally sensitive layer so that a visible indication of the duration of usage is given. In the present case the resistor (2) is in series in closed loop manner with an inductive coil (LC), which when in use is coupled to a coil (L) in the reader. When charging is in progress, RF is induced from an RF source (P) via the coils so that AC flows in the resistor. The usage is monitored optically, e.g. with infra red, and when a card is exhausted, this is indicated. In the case of telephone debit, exhaustion causes call termination. <IMAGE>

Title: Method of uniformly distributing mortar on floors
IPC: E04G21/06
Filed: 1981-11-23
Abstract: In order uniformly to distribute mortar on a floor containing under- floor heating pipes, the invention proposes to deposit the mortar at only one or a few locations of the floor, and then to impart vibrations to the heating pipes. For this purpose, the pipes are filled with water or another flow medium and their ends are connected to a pump operating at a high frequency. The pump imparts vibrations to the flow medium. The vibrations are transmitted to the surfaces of the heating pipes and thus to the mortar. <IMAGE>
Patent GB-2093372-A (GB)
Title: Fan spray nozzle
IPC: B05B1/20
Filed: 1982-01-19
Abstract: A fan spray nozzle 10 comprises a tube having in its wall a fan spray opening formed by a passage 14 of relatively large diameter leading to a conically tapering portion 16, which is intersected by an arcuate groove 18, which is formed in the exterior surface 22 of the tube and the length of which is substantially parallel to the longitudinal axis of the tube. The width of the arcuate groove is smaller than the diameter of the passage 14. The spray opening is formed by a method which includes drilling a pair of diametrically opposed small pilot holes through the tube, drilling completely through one of the pilot holes and through a portion of the opposing hole with a bit having a larger diameter than the pilot holes to form the passage 14 and the tapering portion 16 and the cutting the arcuate groove 18 in the exterior surface of the wall of the tube. The groove 18 intersects the portion 16, and after completion of the spray opening, the pilot hole which has been completely drilled through is sealed with a plug 30. The nozzle has no crevices or joints between parts which could harbour bacteria, but the spray openings produce effective fan sprays. <IMAGE>

Title: Rock cleaving
IPC: E04G23/08
Filed: 1982-05-17
Abstract: A rock cleaving and excavating method according to which a hole (8) is bored in the rock (7) and a cleaving rod (1) is inserted in said hole which rod is provided with a pressure element (6) of elastic material. By compressing said pressure element axially in the hole said pressure element is caused to expand radially and to apply on the wall of the hole a pressing force which exceeds the breaking strength of the rock and cleaves the rock. The elastic pressure element is uniformly pressed also against an uneven wall of a bore hole and produces a controlled cleaving. The cleaving tool comprises a cleaving rod (1) connected to a power means (2) and provided with an elastic pressure element (6) located axially between two axially displaceable supports (4, 5). The supports are displaced by means of the power means so that the supports compress the pressure element axially and force tile pressure element to expand radially in a corresponding manner. <IMAGE>

Title: Two-part metal buckle
Inventor: PIERRON CLAUDE
IPC: A44B11/12
Filed: 1983-05-23
Abstract: In a two-part metal buckle which is intended for steplessly joining textile belts, the co-operating buckle parts (1 and 2) are hingedly joined together by a common axis member (3). The hinges are formed by hinge sleeve portions (9 and 14) which are formed on plate portions (4 and 12) extending parallel to the pivot axis (3), and extend around the common axis member, at displaced positions relative to each other. The hinges are produced continuously in three successive working operations, wherein first the hinge strip portions (9% and 14%) are stamped out, and then pushed past each other, and bent around a wire (3) which is passed at a close spacing above the strip portions (9% and 14%), to form sleeve portions (9 and 14). Finally, the connecting web portions (38) and the wire (3%) are severed between the buckles, and the sleeve portions (9 and 14) are pressed into their final position. In the preferred embodiment, side walls (13) are bent up to cover the ends of the hinge, and bulges 16 are formed in plate (1) so that it is held by friction in the closed position between walls (13). <IMAGE>
