Title: Pumped oil prodn. well has pump body near well bottom - reciprocated via fibre-reinforced plastic cable which may act as signal line
IPC: F04B47/04
Filed: 1981-12-31
Abstract: Pump installation comprises a pump near the bottom of the well and having a reciprocating pump body which is coupled to a drive unit via a pump rod. The pump rod is formed by a tensile-resistant cable-like element, preferably consisting of fibre-reinforced plastic. The fibres are preferably carbon fibres and the cable may contain signal conductors, particularly optical fibre conductors whose physical characteristics are compatible with those of the reinforcing fibres.

Title: Water-cleaning flower bulbs in rotating closed-wall drum - downwardly inclined to discharge end with converging conical wall portion
IPC: A23N12/02
Filed: 1982-02-19
Abstract: Mechanism for removing adhering soil from flower bulbs etc., comprises a largely cylindrical drum which is supported and driven to rotate about its axis, a supply chute for the bulbs and rinsing water at one end, and a discharge chute for bulbs and water at the other end of the drum. The drum wall is un-perforated and has a conical portion converging to a co-axial cylindrical discharge end of smaller dia. The drum axis slopes downwards towards this end such that the water level, which is determined by the water discharge, extends to near the inlet end. Used for removing soil from flower bulbs etc. The inclination and non-perforated wall of the drum provide the same handling capacity with lower water consumption than a larger horizontal drum with perforated wall of prior art. Lower amts. of discharge water reduce the cost of purificn. before disposal.

Title: Energy feedback circuit for electronic printers - incorporates transistorised switch circuit and synchronised back-up energy pulse to stabilise feedback energy levels
IPC: H02M3/28
Filed: 1990-09-06
Abstract: An AC supply voltage (1) is rectified (2) and the ripple removed through capacitors (3). An oscillator (4) is controlled by a control input (5) and generates a high frequency AC supply which is transformed (6) (7) and rectified (9) (11) to form the power supply to an electromagnet (14) operating an ink-jet or pen. The switch (13) connects the energy contained in the electromagnet to a buffer capacitor (16). The charge is fed back to secondary transformer circuit (8) via a freewheeling diode (15). To maintain energy levels when the magnet coil is discharged alternative pulses are obtained via a control signal (12) which drives an auxiliary switching transistor (10) in synchronism with main rectifier (9) conducting period. This results in energy also being supplied to the transformer secondary circuit (8).

Inventor: SCHREINEMACHERS MARIA JOHANNA
IPC: H04L29/06
Filed: 1994-07-11
Abstract: A transmission system for sub-networks having different transmission protocols. Control codes which are assigned to a message in a source sub-network (2) are converted at the transition with a first intermediate sub-network (3), into reference codes which are compatible with a reference protocol ("meta protocol"). Subsequently, control codes are assigned both to the message and to its reference codes, which control codes are compatible with the protocol in the first intermediate sub-network. At each subsequence sub-network (4,5) transition, control codes are always assigned to both the message and to the reference codes, which control codes are compatible with the local protocol of the subsequent intermediate sub-network ("tunneling"). At the interface of the last intermediate sub-network (5) and the destination sub-network (6), after removing the local control codes, the reference codes are converted into control codes which are compatible with the local protocol of the destination sub-network. In this manner "tunneling" is possible with different protocols in source and destination sub-network. In this context, the number of translation modules is restricted. <MATH>
