Abstract: A method and apparatus for marine seismic prospecting in which a long spacing linear array of seismic detectors is spaced from a seismic source and connected to a recording apparatus on a survey ship. A short spacing linear array of seismic detectors is also spaced from the seismic source and signals thereof supplied to suitable channels of the recording apparatus in common with some of the signals from the long spacing detector array. The principal and auxiliary signals in the common channels are distinguishable as a result of relative amplitude and time separation.

Abstract: Sheet material pieces are riveted together by punching a hole in the pieces with a rivet driven through them and into an oversize female die, which is then moved to move the penetrated pieces towards the head of the rivet. The rivet is further advanced so that the end which has penetrated the pieces is flattened and radially enlarged against an anvil. This radially enlarged end may be withdrawn from the oversize female die.

Abstract: A life-saving garment for a person in water comprising a capacious sack integrally formed with legs, sleeves and a hood and open at one end to permit entry by the wearer. An inflatable pocket is hinged at its upper edge to the exterior of the front portion of the garment so as to be swingable about an axis substantially parallel to the line of the shoulders of the wearer, whereby the pocket when inflated can swing to a position keeping the head of the wearer above water regardless of the position of the wearer in the water.

Abstract: Pile fabrics with a pile containing thermoplastic fibers are thermoprinted with a pattern, the contact pressure between the pile fabric and the thermoprinting web in the heating zone being such that about 40 to 60% of the pile is compressed, and immediately afterwards relief-formed and/or surface formed while still hot with a pattern which bears a strict relationship to the thermoprinted pattern. A machine for carrying out this process comprises a thermoprinting unit with adjustable contact pressure and a relief-forming and/or surface forming patterning unit which functions in synchronism and coordination therewith.

Abstract: A multi-roll calender for rubber or synthetic plastics material comprising a pair of rolls mounted at their ends in a calender stand, in which at each of the ends of the pair of rolls, the pair of rolls are rotatably mounted in a bearing block which can be moved to move the pair of rolls together with respect to the calender stand with the gap between the two rolls of the pair rolls maintained constant, one of the rolls of the pair rolls is displaceable relative to the bearing block and to the other roll by having its end engaged in a mounting member which is displaceable in the bearing block, a fixed screw spindle is secured to the mounting member, a rotatable internally threaded sleeve is secured against axial movement in the calender stand and has the fixed screw spindle engagement therein, a drivable worm wheel is rotationally rigidly connected to the internally threaded sleeve, the internally threaded sleeve carries an electromagnetic coupling which can be energised to entrain a spur gear for rotation wi

Abstract: The present invention relates to a process for the preparation of amides.This process for the preparation of an amide by hydrolysis of the corresponding nitrile is characterized in that the said nitrile in aqueous solution is subjected to the action of bacteria having a nitrilasic activity, in that the pH of the said aqueous solution is maintained at a value at least equal to the limiting pH of the amide hydrolysis reaction, and in that the bacteria mass is separated from the amide solution.This process is useful in particular for the preparation of acrylamides.

Abstract: This invention relates to a key system for electronic musical instruments, comprising a key circuit for forming control signals and control circuits for transmitting sound signals in response to the control signals. The key circuit produces the control signals in dependence on the position of a key and/or on elapsed time after depression of the key. Coupling means forming part of each control circuit modifies transient characteristics of the control signals whereby each control circuit can transmit notes in such a way that they each have a different build-up time. This enables the instrument to make a sound similar to that produced by a conventional non-electronic instrument.

Abstract: This disclosure relates to glass annealing lehrs in which glass ware is supported on an endless conveyor to convey it through a closed tunnel consisting of separately controllable temperature zones which expose the ware to a glass annealing temperature gradient produced and maintained by gaseous fuel burners and electrical heaters employed separately or jointly, depending upon the availability of the fuel or electrical energy. In accordance with the invention, circulating fans are positioned at both sides of each lehr section, and air inlet ducts are provided for admitting controlled amounts of ambient air to the inlet of each fan.

Abstract: Apparatus for continuously laminating a continuous strip of chipboard on one or both sides with decorative film comprising means for feeding a continuous strip of chipboard between one or more pairs of rolls together with decorative film and a bonding agent. Means are provided for applying heat and pressure to laminate the decorative film and the continuous strip of chipboard together and embossing the decorative film laminated to the chipboard. In one form of the invention, the chipboard, decorative film and bonding agent may be preheated before being fed to the pairs of rolls, the rolls are preferably heated revolving drums and means can be provided for further heating the laminate before feeding the same through additional heated drums prior to embossing it.

Abstract: A modular flexible wall storage system comprised of a series of cabinets each of which is constructed to be readily adaptable to drawer or shelf storage, as desired by the purchaser. Vertical standards are mounted on the vertical walls of the cabinet and drawer or shelf supporting hardware is alternatively mounted on the standards to support the shelves or the drawers, with the hardware for the latter, and support means mounted on the drawers, permitting relatively frictionless sliding movement of the drawer inwardly and outwardly of the cabinet. Doors can be mounted on the cabinet quickly and easily and can be pivoted a full 180.degree. so as not to extend into the traffic area in front of the system when the doors are fully open. The cabinets are supported on a support assembly which includes leveling means permitting levelling of the support assembly prior to installation of the system thereby compensating for unevenness in the floor or other supporting surface on which the system is installed.

Abstract: An endless belt for use in a machine for laminating a continuous strip of chipboard panel to a decorative film by passing the chipboard and film between a heated revolving drum and the endless belt which is pressed against the drum, wherein the endless belt is formed as a web of flexible steel wire strands preferably including a layer of elastic material such as rubber.

Abstract: A recirculatory analog signal sample amplifier having at least a first prtermined gain is provided with error determining means for recirculating a zero input signal with a second predetermined gain, thereby obtaining an error signal, and correction means to deduct from an incoming sample, before its circulation, a value proportional to the error signal.

Abstract: A process and apparatus for sterilizing loose material, such as flour, cocoa, feedstuffs, fillers for cosmetics and pharmaceuticals, and mould cultures, by means of sterilizing agents, such as superheated steam. The process is a two stage process. In the first stage the loose material is vigorously mixed with the sterilizing agent by means of a mechanical agitator, whilst being brought to the sterilization temperature. In the second stage the loose material is allowed to remain virtually stationary for a predetermined length of time at the sterilization temperature.
