Title: Reinforced elastomeric layer for tubes and belts - with filaments embedded in PVC or nitrile rubber (NL260976)
IPC: B60C9/00
Filed: 1976-03-19
Abstract: An elastomeric reinforced matl. which may be used in a sandwich layer for tubes and belts is made by forming a continuous belt by impregnating in a matrix, a bundle of parallel filaments as they are unwound from a set of bobbins. This matrix has a stripping factor of >=3.15 KN/m pref. >5 KN/m when tested, a tensile strength of >=100 N/test piece, pref. 130 N/piece, and a compressive strength of >=4 MN/m2 at 100% and >8 MN/-m2 at 200%. The ratio of surface area of the matrix to that of the filaments, in cross section is >=1. This matrix is a plastisol such as PVC or contains nitrile rubber and the binder consists of resin precursors which form an aldehyde resin. These resin precursors consist of an aromatic hydroxy cpd. and a cpd. which gives methyl gps. on heating, pref. resorcinol and hexamethylene tetramine.

Patent FR-2354410-A1 (FR)
Title: Liq. treatment of filaments by passage through bath - using guide which pivots to feed filaments under guide roll at the bottom of the bath
Inventor: YTOURNEL MICHEL
IPC: D06B23/00
Filed: 1976-06-08
Abstract: Filaments are liq. treated by being fed through feed rolls into one side of a bath contg. a treatment liq. and being passed under a guide roll in the base of the bath. The filaments pass out of the other side of the bath via delivery rolls. To feed the filaments under the roller the filaments are passed under a main guide mounted on a U-shaped frame which can be pivoted pref. vertically so that the main guide is above the level of the treatment liq. When the frame is lowered into the treatment liq. the main guide feeds the yarn over a fixed guide attached to the end of the guide roll. The fixed guide is a finger which extends upwardly to a positioned below the level of the treatment liq. and which is inclined towards the centre of the feed roll, so that as the filaments are fed onto the fixed guide by the main guide they are fed underneath the guide roll. Manual feeding of the filaments under the guide roll is eliminated. This is important where the treatment liq. is hot or toxic. The device is used for treating polyacrylonitrile filaments to remove dimethylformamide prior to stretch breaking, or dressing cellulose filaments.

Title: Thermostat operating range limiting system - uses pair of stops to limit movement of thermostat setting control
IPC: G05D23/02
Filed: 1976-07-28
Abstract: The thermostat operating range limiting system is applicable to thermostats having a fixed operating range element (8) and movable setting element (1). The limit system uses a pair of stops (5) which can be inserted in various positions in the fixed operating range part of the thermostat. The movable element which carries an indicator (2) comes into contact with the stops which limit the regulating range of the thermostat. In an alternative form the fixed part (8) has an indicator (9). The moving part (10) is connected to the thermostat setting element which has holes (11) in it. Into these holes are placed the stops (12).
Patent FR-2322246-A1 (FR)
IPC: E01F8/00
Filed: 1976-08-30
Abstract: The invention relates to a noise-protection wall which comprises a small number of individual parts, can be easily mounted and is intended to be erected, for example, along carriageways. Said wall has sound-insulation elements which are arranged horizontally between supports (1) and, due to their dead weight and their mutual arrangement, are clamped between side flanges (3) of the supports (1). For this purpose, said sound-insulation elements are arranged one above the other such that they overlap partially in the manner of a slatted blind and are inclined with respect to the vertical. Sheet-metal casings (12, 19), which are preferably open in the direction of the sound source, are used as sound-insulation elements. Absorption material (9) is arranged in said sheet-metal casings, and the latter have at least one perforated side surface (2), preferably consisting of ribbed expanded metal. The sound-insulation elements can be prevented from tilting by wedges which can be clamped to the supports, expediently consist of perforated sheet metal and are preferably filled likewise with sound-absorption material (9).

Title: Rotary motor for liq. or gas - has two cylinders rotating together to prevent friction and noise
IPC: F03B17/00
Filed: 1977-03-07
Abstract: The motor has a hollow outer cylinder (A). Inside is an inner cylinder (B) which has projecting radial arms. The arms run on the inside of the outer cylinder dividing the space between the cylinders into four chambers. There is a fluid inlet port (1) into two of the chambers (P1) which are thus under pressure. There are discharge ports (2) in the other two chambers (P2). The outer cylinder is in equilibrium under the pressures. The inner cylinder can rotate to bring passages (3) in its arms in line with passages (4) in the outer cylinder for communication between the two sets of chambers. The resulting flow produces a rotation and a ratchet locks the cylinders so that they rotate together.

Title: Transfer printing of cellulosic fibres - opt. admixed with other fibres, using crosslinking agents to impregnate the fabrics
IPC: D06P1/56
Filed: 1977-06-09
Abstract: Transfer printing of cellulosic fibres and mixed fabrics contg. cellulosic fibres e.g. cotton/polyester fabrics, comprises impregnating the fabric with a cross-linking agent an then transfer printing from an auxiliary support onto the fabric in the presence of a catalyst. The cross-linking agent is a cpd. of formula (I) where the gps. R are the same or different alkyl of 1-4C or alkoxyethyl in which the alkyl gp. contains 1-4C).

Title: Flexible coupling for gyroscope drive - has solid disc machined to provide two flexible driving strips
IPC: F16D3/00
Filed: 1977-07-11
Abstract: The flexible coupling for driving a gyroscope is machined from a solid disc. Four holes of triangular cross-section with curved sides and rounded corners are cut through the disc. A curved slot (52) extending through an arc of 200 deg. is cut in each end surface. The slots are diametrically opposite and their depth is slightly greater than half the disc thickness. A circumferential slot in the plane of the disc is then cut which runs into the curved slot so that the disc is almost separated into two similar discs being connected only by the thin wall of metal (46) and the flexible strips (26, 28). A further machining operation reduces the width of the strips and separates them with a central slot in the plane of the disc.

Title: Cage for ball bearings - is made of resilient plastics material and allows close spacing of balls using flexible tongues
IPC: F16C33/41
Filed: 1977-07-12
Abstract: A cage for a ball bearing is made from resilient plastics in the shape of a ring which fits between the inner and outer races. The ring (7) has a number of spherical pockets (6) to receive the balls (2). The wall (5) between adjacent pockets is split into t3o tongues (5a, 5b) separated by a V-shaped groove (11). The tongues (5a, 5b) normally conform to the shape of the ball but are sufficiently flexible to allow a ball (2) to be inserted into each pocket (6). This design of cage allows closer spacing of the balls and so increase the load capacity of the bearing.
