Patent NL-7206659-A (NL)
IPC: G04F5/00
Filed: 1972-05-17
Abstract: A highly accurate watch, comprising a quartz crystal time base and a movement controlled by an oscillator regulated to run slightly fast and being periodically connected to the quartz crystal time base. In one embodiment, a pulse counter totals the number of pulses put out by the watch oscillator during its normal operation and activates means to stop the oscillator when a sufficient number of pulses equal to a fixed time period has been reached. A second counter totals the pulses from the quartz cyrstal time reference and reactivates the watch when the number pulses equals the fixed time period thereby wiping out accumulated time errors. In a second embodiment, the output from a balance wheel oscillator and a divided down time base frequency are fed to a flip - flop. The output square wave increases in width due to the frequency difference between the balance wheel and time base and is integrated by an RC circuit. A Schmitt trigger circuit and monostable multivibrator are coupled to the flip - flop so that the trigger circuit is activated for a fixed short time interval and stops the balance wheel through a solenoid. After elapse of the fixed time interval, the balance wheel starts again.

Title: Antenna polarisation assembly for satellite TV reception - can be remotely adjusted for left or right orientated circular polarisation
IPC: H01Q13/02
Filed: 1986-09-10
Abstract: The antenna is used for reception of TV signals from geo-stationary communications satellites. In densely populated parts of the earth, e.g. Europe, two channels may occupy the same frequency band. To differentiate between them, one is transmitted in left rotation circular polarisation mode, while the other is right rotation polarised. The present antenna system has a motorised polarisation mode change-over assembly to allow remote switching. Inside the conventional antenna horn is a fixed phase plate. At the rear of the horn is a cylindrical wave guide attached to a waveguide coupling. Inside the wave guide is a wire polarisation detector which can be rotated through 45 deg. by a shaft coupled to an electric motor.

Title: Preparation to be added to a sports drink, and the formation of a novel type of sports drink for sporting performance improvement
IPC: A23L1/30
Filed: 1993-07-15
Abstract: If as well as carbohydrates a quantity of lipids is supplied to provide energy, better performances are possible. These lipids must not overload the gastrointestinal tract but should on the other hand be rapidly absorbed into the blood. For this purpose we choose medium-chain triglycerides. The form in which the lipids are used is an emulsion. The supplementary sports food is sterilized and provided with a preservative conforming to food and drugs legislation. The invention relates to the choice of the type of lipids which are added as an aqueous emulsion to a 10% strength solution of previously used sports drinks, to make a novel type of sports food. Studies have shown that it is possible to increase the efficiency of energy uptake (during sporting activities) in the muscle cell by the addition of miglyols. The miglyols used include triglycerides of fatty acids having carbon chains of from 8 to 10 carbon atoms, also referred to as MCTs (medium-chain triglycerides). The preparation of the product can be effected via the standard techniques, and on practical grounds it should be sterilized. The ultimately obtained energy-providing novel sports drink contains 23.85 energy per cent of MCT and 76.15 energy per cent of carbohydrates. The sports drink prepared in this manner has achieved surprisingly good results in triathlon, cycling and marathon competitions.

Title: Anti-burglary window stay
Inventor: KRUYDER HERMAN JUSTUS
IPC: E05C17/32
Filed: 1994-04-28
Abstract: A stay comprises two arms (brackets) which at one end are pivotally linked together about a common pivot and at their opposite end each cooperate with a fitting of which one can be fastened to a casing (frame) and the other to a panel which can move with respect to said casing. These arms can pivot between a folded state, in which they are essentially parallel to one another, and an unfolded state. Each fitting is fastened to the corresponding arm via an intermediate piece (intermediate part), each intermediate piece on the one hand having an axis of rotation which runs transverse to the common pivot of the arms, in such a way that in the folded state of the arms said axes of rotation coincide and the arms are able to swivel between a locked position and an unlocked position, each intermediate piece on the other side having a pivot, which pivots on the one hand and the common pivot of the arms on the other hand are parallel to one another in the unlocked position of the arms. One of the arms carries a blocking slot, while the other arm or alternatively the corresponding intermediate piece or fitting carries a locking projection which, at least in the locked position of the arms, cooperates with the blocking slot.

Title: Dispensing system and method with radio frequency customer identification
Inventor: GIORDANO JOSEPH A
IPC: G06Q30/06
Filed: 1998-06-26
Abstract: A system and method for providing a fuel dispenser (14) with radio frequency customer identification capabilities. The system and method determines whether a transponder (23, 25) containing customer identification data is within range of a dispenser (14) that requires activation by the customer to initiate a transaction and has an associated reader (20) for emitting radio frequency signals and receiving customer identification data from the transponder (23, 25) responsive to the emitted radio frequency signals. When the transponder (23, 25) is within range of the dispenser, an in-range indication is provided to the customer. Upon activation of the dispenser (14) following a determination that the transponder (23, 25) is within range, the customer identification data received by the reader (20) is associated with a transaction at the activated dispenser. The transaction at the activated dispenser (14) is then permitted and charged to the customer according to the customer identification data.
