Title: A process for the manufacture of synthetic multifilament threads
IPC: D01D5/30
Filed: 1963-08-21
Abstract: 981,003. Composite polyamide filaments. ONDERZOEKINGSINSTITUUT RESEARCH N.V. Aug. 21, 1963 [Aug. 24, 1962], No. 33140/63. Heading B5B. A composite multi-filament thread is made by simultaneously extruding through each orifice of a spinneret two melts of dissimilar polyamides, and drawing the resultant threads, the polyamides being (a) poly-#-caprolactam and (b) the copolyamide prepared from #-caprolactam and the salt of hexamethylene diamine and terephthalic acid. The composite threads may be sheath/core or side-by-side type. The drawn threads may be crimped by allowing them to relax either immediately after drawing or after winding on a bobbin. During relaxation, crimping may be increased by heat-treatment, using e.g. warm air, warm water, or steam. The drawn threads may be knitted into a fabric, which may be subjected to shrinkage. In one embodiment (Fig. 1) a melt prepared for poly-#- caprolactam granules is fed to chamber 4 via chamber 2 and sand-pack 3, and flows through channel 5 to communal chamber 6. A second melt, prepared from 40 parts #-caprolactam and 60 parts of terephthalic acid hexamethylene diamine salt, is fed to chamber 10 via chamber 8 and sand-pack 9 and flows through channel 11 to communal chamber 6. A composite sheath/ core type multi-filament thread is extruded from orifices 12, is drawn over a pin and then allowed to relax. In a second embodiment (Fig. 2) the two melts enter communal chamber 6 from opposite sides of a partition 13 therein, so that side-by-side filaments are extruded from the orifices 12.

Patent GB-333125-A (GB)
IPC: C06F1/08
Abstract: 333,125. Aktiebolaget Siefvert & Fornander. May 6, 1929, [Convention date]. Matches.-A carrier-bar for bearing splints in match-making machines is adapted for use with either thick or thin matches by having perforations of the different sizes or by forming the perforations with parts of different diameter. In the example, Fig. 3, perforations 7 of smaller diameter are arranged between the larger perforations 6 in each row. To adapt the machine to the smaller matches the filling grate 8, Fig. 4, used for the larger matches may be used but moved laterally to bring the notches opposite the smaller holes 7 in the carrier or a different grate 9, Fig 5, may be used in which the holes are staggered in relation to those of the normal grate. In a modification the smaller holes 7 are made in rows between the rows of larger holes and in alignment with them. In this case the necessary adjustment may be made in the feeding of the carrier bars, the same grate, or one with smaller notches, being kept in the same place, or, without altering the feed, a grate with notches deep enough to allow for the difference in the position of the rows, may be used. In a further modification, Fig. 11, the small holes may be arranged as shown, the appropriate filling grates being shown in section Figs. 12, 13. A form of bar suitable for filling two rows at a time either thick or thin is described having alternate large and small holes along and across the bar. The holes may not be cylindrical but may be as in Fig. 17 with parts of two diameters 14, 15 to accommodate the two sizes or they may be of conical form for the same purpose. A machine with carrier-bars as described may be used, with a filling grate having right and left parts with grooves of different size, for producing simultaneously matches of two different thicknesses.

Title: Seat particularly forl motor vehicles
IPC: B60N2/90
Filed: 1974-07-29
Abstract: 1475799 Fatigue counteracting seat A BECK 29 July 1974 [1 Aug 1973 26 April 1974] 33351/74 Headings A4J and A4M [Also in Divisions A3 and A5] A seat changes its contours at predetermined intervals to counteract fatigue in the occupants back, the occupant being retained in contact with the seat back by a shoulder strap. The contours are preferably changed by inflation and deflation of hollow bodies in the seat and backrest, the shoulders being restrained or pulled back by straps or by U-shaped members fitting over the shoulder. In one form the source of fluid-pressure is supplied to the hollow bodies via a first valving device and exhausted via a second valving device, the valving devices being electrically controlled by a sequence controller programmed by a card. The frequency and amplitude of the deformations may be variable by manned controls on the sequencer. The inflatable bodies and straps or shoulder retainers may be provided with sensors which feedback to the controller to limit the forces applied. When shoulder straps are used the lower ends may be incorporated in a lap strap, which lap strap has a reinforced central portion to maintain the separation of the lower ends of the shoulder straps. OPERATION The sequence of events may be as follows:- (a) forward movement of lumbar and central thorax in conjunction with pulling back the shoulders; followed by relaxation to non deformed state of chair; followed by raising of thighs and backward movement of pelvis; followed by relaxation to non deformed state, or (b) forward movement of lumbar region; relaxation; forward movement of central thorax with shoulders beginning to be pulled back as thorax pressure is relieved, shoulders pushed forward by pads as shoulder tension is relieved; relaxation, or (c) forward movement of lumbar region; relaxation; forward movement of central thorax with simultaneous backpulling of shoulders; relaxation; forward movement of shoulders; relaxation. The seat is particularly suited to use in vehicles to counteract driver fatigue.

Title: Improvements in and relating to calorimetric mass flow meters
IPC: G01K17/12
Filed: 1962-08-30
Abstract: 980, 559. Measuring fluid flow electrically. REACTOR CENTRUM NEDERLAND. Aug. 30, 1962 [Sept. 14, 1961], No. 33397/62. Heading G1N. The mass flow of a gas through a tube 15 is determined by placing the tube across two metal blocks 18, 19 maintained at a constant temperature difference, and measuring the average temperature across the tube 15 by a temperature-sensitive resistance windings 21, this temperature being proportional to the mass flow through the tube, and inversely proportional to the wall thickness. The total gas flow to an ultra centrifuge is measured in this way, and compared with the mass flow of the separated components fed through similar tubes 16, 17, the resistances of the temperature-sensitive windings 21, 22, 23 being compared in a bridge circuit with that of a fixed resistor 24 wound on a reference tube 20, and also located across the blocks 18, 19, whereby the bridge is independent of changes in the temperature difference. Several groups of tubes 15, 16, 17 from different centrifuges are cyclically connected into the bridge circuit, the wall thickness of each tube being proportional to the nominal mass flow through it, so that the bridge unbalance signal represents the same proportional change in mass flow ratio for each group.

Abstract: 1,241,879. Device for controlling laundry dryers. HOLZER PATENT A.G. 3 July, 1969 [11 July, 1968], No. 33578/69. Heading F4G. [Also in Division H3] A control device in a laundry dryer with mechanical movement of. the washing receives an input voltage from a potential divider formed by a variable resistor 1, whose setting determines the final dryness of the washing ,and the resistance which appears between electrodes 4, 5 whenever the washing bridges them. The input signal is stored on capacitor 9 and passed via an integrating network 11, 12 to the ignition electrode 18 of a gas discharge tube 14. As the washing dries the voltage at 18 rises until the tube fires and switches the dryer via relay 15, or operates a programme control unit. In operation even short intervals during which the washing bridges the electrodes are sufficient to charge capacitor 9 completely through the forward biased diode 8, although the discharge time of the capacitor through resistor 10 and reverse biased diode 8 is of the order of the drum revolution time. Because of the integrating network 11, 12, the voltage at 18 does not alter appreciably during several drum revolutions. Instead of the tube 14 a switching circuit using semiconductor devices can be used, as in Fig. 2 (not shown)- (see Division H3).
