Title: Injection moulding plastic lenses - in a cavity of reducible size having an overflow pocket
IPC: B29D11/00
Filed: 1977-01-24
Abstract: The appts. includes a pair of cavity defining dies movable towards each other after injection and an overflow pocket adapted to receive the excess material forced from the cavity.

Redn. of the cavity size enables thin lenses, both concave and convex to be formed. A lens can be formed which required no finishing operation, such as grinding.
Patent NL-7708228-A (NL)
Title: Ink jet printing - uses non"clogging primary jet from nozzle to entrain secondary fluid containing pigment
IPC: B41J2/135
Filed: 1977-07-25
Abstract: A method of producing an ink jet recording utilises a jet of liquid expelled under pressure from a nozzle and the production of very fine liquid droplets at a droplet formation point, which are then directed onto the receiving surface. The liquid jet is produced by a primary jet expelled from the nozzle through a thin layer of a secondary fluid. The primary liquid and secondary fluid then combine to form the ink jet. Used for the prodn. of ink jets directed onto the target sheet by either the Sweet process or the Herts-Simonssen process. A pure liquid of very low viscosity can be expelled from the nozzle, while a pigment-containing liquid can be used for the secondary fluid; in this way the difficulties associated with the ejection of a satisfactory coloured jet through a nozzle are overcome by the use of a pure liq. while a pigment-contg. liquid, comprising particles which could obstruct the nozzle, is combined into the final flow since the pigment is downstream of the nozzle outlet. Thus a satisfactory dark pigment can be obtd. in the final recording.

Title: Hydraulic-pneumatic drive for down hole oil well pump connecting rods - has pneumatic constant pressure cylinders to balance weight of assembly and hydraulic accelerating and retarding cylinders
IPC: F04B47/04
Filed: 1978-06-19
Abstract: Reciprocating downhole oil well pump is driven via a connecting rod string by means of a hydro-pneumatic drive comprising >=1, single acting pneumatic cylinder coupled to a constant pressure gas reservoir and >=1 double acting hydraulic cylinder. The gas cylinder piston exerts an upward force on the pump con-rods equal to the average of the maximum tension force on the up stroke and the maximum tension force on the downstroke, whilst the hydraulic cylinder drives both up and down in such a manner that the velocity/time characteristic of the pump is approximately sinusoidal. The pref. drive assembly comprises a series of alternate gas and hydraulic pistons distributed in a circle around the pump rods and attached to the upper end of the rods via a cross-head. The gas cylinders are connected to a nitrogen buffer vessel with a capacity several times greater than the total capacity of the gas cylinder and the buffer vessel is coupled via a pressure regulating device to a nitrogen reservoir. The double acting hydraulic cylinders are coupled to two horizontally opposed single acting pump cylinders driven by a crank shaft via a step-down gearbox, flywheel and electric motor. The flywheel is on the motor side to reduce its weigth and is of sufficient mass to ensure its constant rotational speed and, consequently, a sinusoidal output from the hydraulic pumping cylinders. The hydraulic system is also connected to an oil pump and reservoir which compensate for fluid leakage. The drive is much lighter than the traditional mechanical crank arm and balancing wheel drive.

Patent NL-8503478-A (NL)
IPC: H03H17/06
Filed: 1985-12-18
Abstract: In a sample rate converter having a non-rational conversion factor the input samples coincide with low-rate clock pulses and the output samples coincide with high-rate clock pulses, or inversely. It comprises a filter coeffi­cient generator 3 which, based on the distance (deviation) between a low-rate clock pulse and the immediately preceding or immediately subsequent high-rate clock pulse, con­tinuously supplies a series of filter coefficients. To de­termine the deviation a phase-locked loop (30) is provided, with a phase detector (301) receiving the low-rate clock pulses as well as synthetic low-rate clock pulses and supplying a discrete-time phase difference signal u(.) which is applied to a processor circuit (302). This circuit supplies the desired deviation d(.) and a reference number N which is applied to a counter circuit (304). This circuit also re­ceives the high-rate clock pulses and each time after re­ceiving the number of clock pulses corresponding to the reference number it supplies a synthetic low-rate clock pulse. In the processor circuit 302 a filtering operation (3021) is first performed on the discrete-time phase dif­ference signal u(.) so that control signal samples H(.) are obtained. An auxiliary sample s(.) is subtracted from such a control signal sample and the difference is divided by a weighting factor incr. of the number P thus obtained those bits whose significance is less than 2° represent the deviation d(.), while the other bits represent the reference number N. By subsequently multiplying the deviation d(.) by the weighting factor incr, a new auxiliary sample s(. + 1) is obtained.

As a rule, a new casing is prepared for each series of cross-ties type. In small series with various positions of the construction components it is economical to use the bottom plate repeatedly. This is done by providing the bottom plate, prior to its insertion in the casing, with holes (A,B,C) for several types of finished parts, by provisionally closing the unnecessary holes by suitable means and by finding the combination of holes required for the production of a certain type of finished part through a certain searching procedure and freeing them of their provisional closing means.
