Title: High density high glass polymers
IPC: C08F279/02
Filed: 1969-07-22
Abstract: Water is added to a soln. of a rubbery conjugated 1,3-diene polymer which is dissolved in a monovinyl aromatic monomer, whereupon the soln is polymerised in usual polymerisation conditions until the size of the rubber particles produced is reduced by phase inversion to the desired size, using a machine treating apparatus in which a circular flow occurs and which is fitted with grinding and comminuting devices, a liquid-circulation device and perforated baffle sheets which are arranged in such a way that the entire stream of liquid passes through the perforations. Subsequently water and an inorg. suspension-stabilising medium is added to the soln and the mixture continues to be polymerised in suspension.

IPC: G03B42/02
Filed: 1975-04-24
Abstract: A precision X-ray diffraction camera, consisting of a pair of kinematically connected frames, pivoted to swing about vertical axes, a film holder with film cassette, and a crystal holder with a holder for the goniometric head all turning about horizontal axes, the whole forming a unit with an axis of precession supported in a drive segment, passing through the crystal, and perpendicular to the vertical axes of rotation of the two frames, and with a collimator opposite to the crystal on the same axis. The carrier of the goniometric head with the crystal are arranged to slide in a unit which forms a quarter of a circle integral with the crystal holder of which the axis is perpendicular to the precession axis and the axis of the goniometric head and passes through the crystal, passing through a point where the axis of the collimator, that of the vertical crystal bearing intersect. The arrangement makes it possible to utilise a displacement through a full 90 deg. of the holder of the goniometric head so that exposures can be made in the area of back-scattered radiation and of reciprocal planes in any direction with a single mounting of the crystal.

Title: Flow-meter for tap water - has paddle wheel turbine which rotates pointer through geared drive
IPC: G01F15/18
Filed: 1979-10-12
Abstract: The outlet of the tap (1) brings the water into a vertical housing (6) which contains a water-wheel type of a turbine (7). After turning the wheel, the water leaves the housing via a splash prevention nozzle (4). As the wheel is turned by the flow, the spindle of the wheel turns a reduction gear-chain (8-13) which ends in a central axis (14). A pointer (15) which is fixed onto the axis, turns against a circular calibrated scale (16) to indicate the flow. The gear ratio is chosen so that the pointer makes one revolution per litre of water used. As the use of water usually involves the use of energy, this flowmeter can be used to remind user to be economical.

Patent NL-8700282-A (NL)
IPC: H01L27/148
Filed: 1987-02-06
Abstract: The invention relates to a charge-coupled image sensor arrangement, in which in the case of overexposure the excess of generated electrons is drained in vertical direction to the substrate. In order to adjust the maximum acceptable extent of overexposure, means are provided, with the aid of which an additional low voltage can be applied to the blocking gates. As a result, it is possible to adjust the maximum overexposure without the maximum white level being variable. Due to the fact that the said blocking voltage is a d.c. voltage, the dissipation substantially does not increase.

Patent NL-9001157-A (NL)
IPC: G02F1/313
Filed: 1990-05-17
Abstract: In a digital optical switch which is based on the mode-selectivity principle, made up of a passive section (A) containing a first optical wave guide (1) and a second optical wave guide (2) and a switching section (B) containing a third optical wave guide (3) and a fourth optical wave guide (4), both the required asymmetry and the bringing of the optical wave guides within or outside each other's interaction region are achieved with the aid of curves (K1, K2) in said optical wave guides. In the switching section (B) said asymmetry is switchable. Use is made of the effect that a curve results, in general, in a reduction of the propagation constant in the optical wave guide. Suitable curves are of circular-arc shape and sinusoidal. The switching section (B) may furthermore incorporate a short intermediate section (s-u) in which the optical wave guides (12, 13) run straight at a small mutual angle ( PHI ) in the event that the switchable asymmetry is in the first instance too small with a particular choice of material. The invention makes possible much shorter switches which have a greater packing density. <IMAGE>
