Title: Process and apparatus for treating a continuous length of synthetic textile fabric for the purpose of making the material softer, less glossy and more voluminous
IPC: D06C21/00
Filed: 1965-10-08
Abstract: A process for treating a continuous length of synthetic textile fabric to make it softer, less glossy and more voluminous, in which the fabric is subjected to treatment in a strongly attacking shrinking bath, while at the same time being subjected to ultrasonic waves and is immediately thereafter washed with a washing liquid that may contain a neutralizing agent for the shrinking liquid, is characterized in that the fabric is passed through a shrinking bath 1 in a path extending under a perforated conveyor belt 6 immersed in the bath, the speeds of supply and removal of the fabric to and from the bath and the speed of belt 6 being so mutually adjusted that practically no tensile stresses occur in the fabric, and the latter is caused to follow a path of movement extending substantially along the underside of the belt 6. The fabric is fed into the bath from roll 13 by feed rolls 11 and withdrawn over roll 17 and the speeds of rolls 11, depositing roll 12, belt 6 and roll 17 are adjusted accurately relative to one another, depending on the degree of shrinking of the fabric, by means of known continuously variable transmissions and/or separate variable speed motors. Shrinking liquor is fed to the bath 1 by perforated tube 8 extending across bath 1 and discharged through perforated tube 9, these tubes being connected by an external circulating system (Fig. 4, not shown) including pump 41, filter 42 dosage apparatus 43 and heater 44. In the bottom of vessel 1 a battery of ultrasonic oscillators 18 is arranged for emitting ultrasonic vibrations towards the fabric on the lower run of belt 6. After withdrawal from bath 1 the fabric is fed into a neutralising and washing vessel 19 (Fig. 2, not shown) where it is conveyed on the upper surface of belt 25. The vessel 19 is divided by partitions 20 into three collecting tanks 22, 23, 24 with overflow troughs 31-35 arranged above the upper run of conveyor 25. Trough 31 is supplied with cold water and the collected liquor in tank 22 is fed back to trough 32 and so on, the liquor being heated and having a neutralising agent added before it is fed to trough 35 (Fig. 5, not shown).

IPC: B62D5/06
Filed: 1967-02-23
Abstract: In power-assisted steering mechanism for a motor vehicle including a pin 48 connecting a rocker shaft lever 43 to a connecting rod 41 coupled to an hydraulic piston 42, a circlip 46 located in a groove in the connecting pin bore provided in the connecting rod 41 acts as a stop for the pin 48 when the pin is inserted through an access opening 49 in the housing 1, and an undercut conical spigot 50 on the pin 48 facilitates withdrawal of the pin through the opening 49. A second circlip 47 retains the pin 48 in the bore. A detachable cover plate 2 seals the access opening 49.
Patent ES-344302-A1 (ES)
Title: Method of bending glass sheets
IPC: C03B27/044
Filed: 1967-08-21
Abstract: In a machine for bending glass sheets on a ring mould, the mould is accelerated upwardly to engage the mould sufficiently rapidly to cause bending to take place principally by inertial forces. The sheets S are heated at B and conveyed to bending area C and heat tempered at D in known manner. Rolls 28 receive the sheet which is then engaged by bending mould 34 of open ring-type. This engagement is effected by a fluid cylinder 41 and the mould may be vibrated rapidly vertically to apply further inertial forces. A cooling device 56 may be oscillated across the bent sheet and gas jets directed on the sheet from tubular members 58 and 59 to cool it sufficiently to give it rigidity for subsequent movement to the tempering zone D.

Title: Coaxial multi-stage rotory compressor
IPC: F02B53/00
Filed: 1967-12-05
Abstract: ' A rotary multi-stage sliding vane compressor comprises an outer casing 3, Fig.3, having an elliptical bore, an inner body 4 having an elliptical peripheral surface fixed to and concentric with the outer casing, a double-walled cylindrical rotor 5 whose outer surface engages the ends of the minor axis of the outer casing bore to provide two equal volume outer chambers 15, 16, whose inner surface engages the ends of the major axis of the inner body peripheral surface to provide two equal volume inner chambers 21, 22 and a plurality of equal length blades 10 freely slidable in radial slots in the rotor and in end abutment with the bore and peripheral surface. Air is admitted to the outer chambers 15, 16 through inlet ports 17, 19 respectively and after compression is discharged through outlet ports 18, 20 into a receiver (6), Fig.4 (not shown) where it is cooled or alternatively into an axial bore in the inner body. The air is then admitted to the inner chambers 21, 22 through inlet ports 23, 25 respectively and after further compression is discharged to a second receiver (11). Pressurized cooling oil circulates across the contact surfaces of the rotor, fills chambers between the walls of the rotor and at the same time lubricate the blades. The blades are hollow and formed with longitudinal and transverse ribs and with the aid of centrifugal force a liquid coolant circulates through the blades. The ends of the blades may be sealed with respect to the bore and peripheral surface by means of elastic material or articulated tilling parts. The pressures in the two receivers may be regulated by spring-loaded valves. The compressors may be used as superchargers.

Title: Hydraulic coupling
IPC: F16D47/06
Filed: 1970-04-30
Abstract: The turbine wheel 18 of an hydraulic coupling is connected to an output shaft 20 by a ratchet clutch 19 comprising an intermediate ring 26 helically splined at 27, 28 to a hub 22 of the turbine wheel 18 and carrying clutch teeth 31 engageable with teeth 32 on the output shaft 20. Helical movement of the ring 26 to engage the teeth 31 synchronously with the teeth 32 is initiated by a pawl 33 engageable with the teeth 31. The clutch 19 may be held engaged for bi-directional drive by a piston 34 splined at 42 to the hub 22 and engageable with teeth 44 on the ring 26. The piston 34 is biased towards engagement with the teeth 44 by a spring 45 and is moved left against the bias of the spring 45 by supplying pressure liquid to a chamber 39. In a motor vehicle transmission system, Fig. 6, pressure liquid is supplied to the chamber 39 from a pump 52 through a valve 48 when a gear shift lever switch 56 is closed. The clutch 19 is thus normally held engaged for bidirectional drive by the piston 34 and is released for one way drive during ratio shift. A centrifugally controlled valve 57 vents the fluid coupling at engine idle. In Fig. 7 (not shown), a piston (60) acts on the intermediate ring (26) to disengage the clutch at engine idle. In Figs. 7 and 8 (not shown), the pawls (33) are carried by the intermediate ring and engage the teeth on the output shaft.
