Title: Method of making a tubular member by helically coiling a metallic strip, tubular member produced by this method and device for carrying out this method
IPC: B21C37/22
Filed: 1970-07-08
Abstract: A strip having hooked edges is laterally curved and coiled into a spiral in which the hooked edges of adjacent coils overlap. Just before the coils are overlapped the strip is formed into a helix the turns of which slant in a direction opposite to that of the turns of the helix finally formed so that when adjacent turns are forced into engagement with each other adjacent turns are resiliently biassed toward each other. The invention includes apparatus adapted to carry out this method and the tubular member produced thereby.

Patent ES-423283-A1 (ES)
Title: Electrical contact receptacle with helper spring
IPC: H01R13/11
Filed: 1974-02-15
Abstract: The present invention relates to a female electrical receptacle for receiving and making electrical contact with a male electrical terminal. One side of the receptacle is in the form of a resilient leaf spring folded about a side margin thereof which is integral with the receptacle. The leaf spring resiliently engages against a male terminal received in the receptacle to make an electrical connection therewith. The receptacle is further provided with an elongated helper spring folded about a side margin thereof which is integral with the receptacle. The helper spring is shorter than the leaf spring and has a free end which overlies the leaf spring. Upon insertion of a male terminal into the receptacle, the male terminal will resiliently deflect the leaf spring contact against the helper spring. The helper spring thereby serves to stiffen the spring contact to provide a relatively high gripping pressure on the male terminals. The spring contact further is deflected by the male terminal into engagement with the helper spring along its folded edge margin which resists the tendency of the spring contact to unfold and further serves to limit the deflection of the leaf spring to prevent deformation thereof. The helper spring also distributes the stresses along a substantial length of the leaf spring to prevent deformation thereof due to overstressing. In a modification, the receptacle may be provided with a folded tab portion overlying the free end of the spring contact against which the free end of the contact will engage to limit the deflection thereof when a male terminal is received in the receptacle.

Patent ES-442846-A1 (ES)
Title: Gas sampling analyzing system
IPC: G01N1/24
Filed: 1975-11-20
Abstract: A gas sampling analyzing system is provided whereby flue or process gasses are aspirated from a process duct to an analyzer and are therefrom returned back to the process duct to prevent condensation at the system exhaust.

Title: Record carrier with an optically readable trackwise-arranged information structure and apparatus for the read-out thereof
IPC: G11B7/24085
Filed: 1976-08-24
Abstract: It is intended that a read-out spot (V1) can be addressed quickly to a particular information part of the recording carrier (1). The tracks (2) of the recording carrier (1) are subdivided into two groups (a, b). The spacing (d1) between the tracks of the first group (a) is constant, as is the spacing (d2) between the tracks of the second group (b). The second spacing (d2) is greater than the first spacing (d1). The variation in the spacings (d1, d2) between the tracks (2) is about 10% of the average spacing. A read-out beam (11) of a laser (10) is focused by a lens (16) at the read-out spot (V1) on the recording carrier (1). After the reflection at the recording carrier (1), the read-out beam (11) is passed to a detector (14). In order to establish whether the read-out spot (V1) is addressed to the desired group of tracks, an auxiliary beam (l) is used. The auxiliary beam (l) is launched into the path of the read-out beam (11) and produces an addressing spot (V2) on the information carrier (1). The reflected part-beam (l+1) is reflected to two detectors (4, 5), which are connected to a differential amplifier (6).

Title: Device for cooling the picks of cutter heads and the working face and for preventing the formation of dust.
IPC: E21C35/23
Filed: 1979-10-09
Abstract: An assembly for cooling the teeth of the cutting heads of a mining machine and, at the same time, the rock face. The cutting heads are rotatably supported and, at the same time, the rock face, the axis of rotation being essentially horizontal. Cooling is performed by water jets distributed by spray nozzles. In order to obtain a sufficient cooling effect for the cutting teeth and the rock face with a water consumption as low as possible, there are provided on the jib arm two groups of spray nozzles for each cutting head. The nozzles of the first group are directed to the region of the teeth in the highest position of the same while the nozzles of the second are directed into the interspaces between the rows of teeth in the said region. The flow of water can be shut off separately for each group of nozzles associated with each of the cutting heads. Since with a mining process in horizontal lines only one cutting head contacts the mining face, in this case flow of water is permitted only to the cutting head which is actually working. Water supply can be shut off separately for each of the two cutting heads.
