Title: Electromagnetic actuator for hydraulic proportioning valve - has ring armature causing axially inclined flux to allow selection of characteristics
Inventor: VERMEYEN LEO DIPL ING
IPC: H01F7/16
Filed: 1974-12-11
Abstract: The electromagnetic device for operating hydraulic proportioning valves has a coil wound around an axial cylindrical core of magnetic material and enclosed within a tubular housing. The operating rod (7) has an armature ring (6) fixed to its end, its face (9) being laterally arranged to that (8) of the core (1). The inner diameter of the armature ring is greater than the outer diameter of the core so that a gap is left between the two. The magnetic flux is therefore inclined to the axis of the device and is located in this gap. The ring armature allows the device force-distance characteristics to be simply set as required.

IPC: H04Q3/00
Filed: 1974-12-18
Abstract: The excitation is provided by a switching device marking engagement of transmission units which can be interconnected through the reflection switching panel, in order to operate a selection chain oriented to the number of intermediate lines in the various bundles. The intermediate lines in each line bundle are divided in several groups with a number of lines at the most equal to that in the smallest bundle, the same in all groups. The switching device marking signals so energise an initial evaluating device with a number of switching stages corresponding to that of groups in the largest bundle that only one group, containing at least one free intermediate line, is connected to a common selection chain, whose number of switching stages correspond to lines in each group.
Patent DE-2461352-A1 (DE)
Title: Ground drill with underpressure - has tool sealed from superposed water column and directed drilling return flushing up rods
Inventor: LAUFER KLAUS DIPL ING
IPC: E21B7/00
Filed: 1974-12-24
Abstract: The ground drill operates on the return flushing principle involving underpressure in the tool area. The tool is sealed from the water column which acts as its superposed load. In this way it is possible to direct the flushing water in required channels to optimise drillings recovery through the hollow drill rods to the surface. Thus the channel effect can be adapted to suit the tool design, preferably when handling cohesive soils which tend to clog the tools and prevent the drill from attaining desired footage. The suction effect keeps the tool clamped to the drilled ground, and the kinetic force of the flushing water maximises the drilling action, whilst at the same time preventing ground sticking.

Title: Colouring textiles contg. cellulosic and polyester fibres - with disperse and reactive dyes to give level, wet-fast colorations
Inventor: ONG SIEN LING DIPL CHEM DR
IPC: D06P3/52
Filed: 1976-08-07
Abstract: Mixts. of cellulosic and synthetic fibres can be coloured by impregnating them, in an aq. organic medium with aq. compsns. contg. (a) organic colourants (viz. pigments and/or disperse dyes); (b) surfactants (either ionic or non-ionic); (c) carries of limited aq. solubility (e.g. biphenyl, benzophenone); (d) organic solvents (e.g. hexane or benzene); and (e) thickeners (e.g. carboxymethyl cellulose, alginates) and then fixing the dyeings or prints in the usual way, of the organic solvent (d) is soluble in water (e.g. alcohols or esters), the carrier (c) can be omitted. Because of difficulties inherent in dyeing such mixts. pigment printing is often used, but the prints often have poor fastness to rubbing and a poor handle. Dyes can be used if water-soluble glycol derivs. are used as solvents for them, but the choice of dyes is limited; the solvents act as retarders of dyeing of the synthetic fibre component, as a result of which high-fixation temp. are necessary, but this tends to yellow the cellulose component and impair the handle. Process overcomes these difficulties and gives level dyeings and prints characterized by good solidity, brilliance and intensity and good wet fastness. In addn. the print pastes and pad-baths ae stable and can be prepd. in advance.

IPC: H01R9/05
Filed: 1976-09-09
Abstract: A contact connector for the outer screen of a high frequency coaxial cable in the form of a split collar into which the cable is introduced from the side. The split outer sleeve (2) contains a spring ring (3) with inwards projecting spring leaves (4) which make contact with the cable. The spring ring (3) is attached to effect an electrical connection with the outer collar (2) along the edges of the longitudinal slit through which the cable is introduced. The arrangement makes it unnecessary to slide a connector axially along the cable, which is liable to cause damage, and maintains radial pressure if there is any flow of the dielectric under pressure.
