Patent GB-1514085-A (GB)
Title: Ink-jet printers
IPC: B41J2/175
Filed: 1976-06-23
Abstract: 1514085 Ink jets SIEMENS AG 23 June 1976 [29 Sept 1975] 26069/76 Heading B6P An air bleed device in an ink jet printing head has a passage 6 whose diameter is such that, following pressurization of the ink supply to raise the level of ink in the disbributor 5 so as to expel air, ink will be retained in the passage 6, even if this ink is in contact with air cushion 10, and thereby provides a seal. Expelled air leaves the head via passage 8. Enlargement 7 receives ink flowing through the passage 6 when the ink level in the distributor 5 is raised and provides ink to refill the passage 6 should air be expelled and the ink in the distributor never reaches the level of the passage 6 in any subsequent bleeding operation.

A seal is effected between the couplings 14, 16 by 0-rings 32, 34. The female coupling 14 is formed on its outer surface with slots 62 (Fig. 10), also shown in dotted lines in Fig. 4 ,and the couplings 14, 16 may be locked against rotation from the position in which the screw threads are engaged by pivotal movement about a bolt 68 of a T- shaped latch 66 having a head 70 to engage in one of the slots 62 and to be held therein by a pin 72.
Patent GB-1475606-A (GB)
Title: System for influencing the operation of internal combustion engines
IPC: F01N13/02
Filed: 1974-06-13
Abstract: 1475606 Automatic control systems ROBERT BOSCH GmbH 13 June 1974 [14 June 1973] 26227/74 Heading G3R In a vehicle engine fuel injection control system, the exhaust temperature of each of a plurality of engine cylinders is monitored, and fuel injection is stopped to any cylinder whose exhaust is at too low a temperature. Such low temperature is taken to indicate too much unburnt fuel in the exhaust and the object is to prevent such unburnt fuel causing overheating of a catalytic exhaust decontaminator. Fig. I shows the cylinders 12 to 15 whose respective exhaust temperatures are monitored by devices 32 to 35 which are located upstream of the ultimate exhaust channel which in turn contains catalytic reactors 26, 27. Fuel injection valves 37 to 40 are made responsive to the devices 32 to 35 to cut off fuel supply to any cylinder whose exhaust is sensed as too cool. Fig. 2 depicts the control circuitry of such a system for the case of three cylinders with respective temperature sensors 32, 33, 34 in the form of NTC thermistors. The diodes 48, 49, 50 have the effect of determining the potential of the base, and hence the emitter, of a transistor 51 in dependence on whichever of the thermistors has the lowest resistance. 54 is a Zener diode. Hence the inputs via resistors 55, 63, 66 to each of the amplifiers 56, 61, 65 exceed the emitter voltage of the transistor 51 by the breakdown voltage of the diode 54. These equal inputs thus represent a permitted minimum temperature of a predetermined amount less than the hottest cylinder exhaust. If any of the thermistors 32 to 34 detect a lower temperature than this permitted minimum, its output to the associated amplifier, upon inversion at the amplifier input, causes cut-off of the amplifier and consequent de-energization of a relay 68, 69 or 70, and the latter shuts down the fuel injection to the relevant cylinder. Figs. 3 to 5 (not shown) depict modifications of Fig. 2. In Fig. 3, means are provided to respond to short-circuiting of any thermistor, a condition which would otherwise be interpreted as a high temperature, and shut off the fuel supply valve in this eventuality. In Fig. 4, like means are used to provide a signal if any thermistor breaks down, either to an open or a short circuit state, but without accompanying shut-down of the fuel supply. Fig. 5 depicts a modification of Fig. 2 in which, by omitting the diodes 48 to 50, the permitted minimum temperature is established by reference to the average temperature of the thermistors instead of that of the hottest.

Title: Improvements in or relating to ultra-short wave directional couplers
IPC: H01P5/18
Filed: 1955-09-19
Abstract: 784,364. Waveguide directional couplers. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Sept. 19, 1955 [Sept. 22, 1954], No. 26693/55. Class 40 (8). A directional coupler comprises crossed rectangular and coaxial guides 1, 2 having two similar holes 4, 5 in a common wall, the holes being spaced apart an odd number of quarterwavelengths in the guide and a second odd number of quarter-wavelengths in the coaxial line, the second odd number exceeding the first. In the Figures the holes are spaced by #g/4 in the rectangular guide (where #g is the rectangular guide wavelength) and by 3#a/4 in the coaxial line (where #a is the coaxial line wavelength). The coaxial line may lie adjacent to either the broad or narrow faces of the rectangular guide, the directivity effect being opposite in the two cases. The maximum possible distance between the holes occurs when they are placed at the edges of the rectangular guide. If this distance is less than the required odd number of quarter-wavelengths in the coaxial line the coaxial line wavelength is reduced by a partial or complete filling of dielectric material. In order to obtain uniform characteristic impedance the diameter of the inner or outer conductor of the coaxial line is altered in the region of the dielectric filling. The degree of coupling varies with the angle of intersection of the guides and is a maximum in the arrangement of Fig. 3 where the coaxial guide 2 crosses the rectangular guide twice at right-angles.

Title: Process for the manufacture of crimped fibres and filaments
IPC: D01D5/23
Filed: 1970-06-03
Abstract: 1316678 Developing crimp in filaments FARBWERKE HOECHST AG 3 June 1970 [3 June 1969] 26782/70 Heading D1F A process for the manufacture of threedimensionally crimped fibres and filaments of synthetic high-polymers from filaments or tows which are wetted, and to which a latent crimp has been conferred by producing an orientation gradient over their cross-sectional area, comprises drawing the filaments or tows, drying them at a temperature ranging between 20‹C below the second order transition temperature and 35‹C below the melting point of the filaments, without permitting shrinkage, and then developing the crimp at a temperature ranging between 10‹C below the second order transition temperature and 35‹C below the melting point of the filaments, without applying tension. The preferred temperature ranges are stated to be as follows; drying-between 90‹C and 160‹C; developing the crimp-between 60‹C and 230‹C, preferably 90‹C to 130‹C. The filaments may be cooled after drying and then subjected to heat treatment to develop the crimp. The synthetic filaments may be of polyester, or polyester amide, preferably polyethylene terephthalate. In a preferred embodiment, the filaments are drawn during the drying and cooling processes by from 1 to 50%. preferably 1 to 10%, based on the length of the filaments before this drawing process. The drying may be effected by passage of the filaments or tow about a heated draw roll, and cooling by passage about a cooled draw roll. The crimp is preferably developed by allowing the filaments to fall freely onto a conveyor belt, and directed superheated steam through the tow. The undrawn filaments or tow may be passed through a brightening bath which bath may also contain substances favourably influencing the sliding and adhesion properties of the fibres and preventing electrostatic charges. Drying of the filaments or tow may also be effected on a heated metal surface, in hot air, by infra-red heating or in a high-frequency alternating electromagnetic field.

Filed: 1972-06-09
Abstract: 1399609 Knitting-machines TESALON ANSTALT 9 June 1972 [15 June 1971] 27016/ 72 Heading D1C In a knitting machine the position of a thread guide or carriage is sensed, and a representation of the design scanned synchronously so that the thread guide can be moved between two positions at the dictates of the reader. In a flat-bed machine an electrical detector 1 is fixed to the carriage. It includes two elements 10, 11 whose capacity varies as the carriage passes acrosss the needle bed 2, and give rise to a series of timing pulses. The pulses drive a motor which via a rack and pinion moves a photo-electric detector to scan a pattern on a drum. The drum is stepped on by an amount corresponding to the needle guage at the end of each carriage traverse. Initial positions of the drum and device are sensed photo-electrically. A rotatable thread guide is mounted on the carriage so that either of two yarns is fed according to the pattern. The guide is rotatable by a member moved by electromagnets. Corrections are incorporated to allow for response times and the movement of the guide relative to the carriage at the end of each traverse. If used with a circular machine the drum is rotated step wise by the timing pulses and the detector realigned axially at each revolution.  For Figure see next column
