Title: Method and apparatus for detection of missing pulses from a repetitive pulse train.
Inventor: ANDERSSON CLAES GEORG
Filed: 1997-02-07
Abstract: A method and apparatus for detection of missing pulses from a repetitive pulse train including signal detection circuits for capturing the rising and/or falling edges of an input signal, time-stamping the captured edges, calculating the maximum and minimum instantaneous frequency over a specified time period, and displaying such frequency values. Instantaneous frequency values between any two adjacent edges are calculated based upon the time-stamps of the edges. The instantaneous frequency values in a specified time period are then sorted to find the minimum and maximum frequency values for that time period. These instantaneous frequency values are displayed in the form of a histogram evidencing the occurrence or lack of occurrence of missing pulses from the input signal.

Title: Pressure equaliser for domestic waste water system - has rubber valve lifted by atmospheric pressure for fresh air ingress
IPC: F24F7/04
Filed: 1975-08-15
Abstract: The vent pipe (1) from the waste water system has a hole (2) a short distance from its top, and through this is fixed a piece of piping (3) being bent to terminate in a vertical, upwards position inside the vent. A semi-circular rubber valve (6) sits on this short pipe and the vent pipe is capped (4). Sufficient clearance is present between seal and cap to allow movement of the cap to allow air flow through the pipe but not for dislodgement. The assembly is insulated against cold weather (5). After flushing the water closet the system pressure will be less than atmospheric and the atmosphere pressure will lift the valve and permit entrace of fresh air.

Title: Liq., esp. water or oil, medium presence detector - has sensor with swelling body activating galvanic element to produce electric current when electrolyte is supplied to chamber
IPC: F16K31/00
Filed: 1978-09-22
Abstract: The device for detecting the presence of a liquid medium comprises an ampule containing an electrolyte liquid. A galvanic element has an electrolyte chamber which in its inactive state lacks electrolyte. The galvanic element is capable of producing an electric current when electrolyte is supplied to the chamber. A sensor activates the galvanic element in response to the presence of the liquid to be detected. The sensor includes a body which swells upon contact with the liquid to be sensed. The swelling of the body effects transfer of electrolyte from the ampule to the electrolyte chamber.

Title: Automatic reversible gear coupling - has input shaft, opposite action one way couplings and gear wheels giving one way output irrespective of input rotation
IPC: F16H31/00
Filed: 1979-03-05
Abstract: The gear coupling has an input shaft (A) and an output shaft (B) which are coupled via one-way couplings (c, k, l) and gear wheels (1-6) such that the output shaft rotates in the same direction irrespective of the direction of rotation of the input shaft. The shaft (A) drives gear (1) on shaft (B) via the left-hand one-way coupling whilst the right-hand one-way coupling permits gear (6), driven via gears (2, 3, 4, 5), to rotate in opposite direction. On reversal of shaft (A) the action of the one-way couplings is reversed and shaft (B) is driven via gears (6, 5, 4, 3, 2, 1).

Title: Secam colour TV transmitter with coding circuit - has two reference signal generators, two sampling circuits, each with phase regulator
IPC: H04N11/18
Filed: 1979-06-22
Abstract: The coding circuit is for a SECAM colour television transmitter. It has a frequency modulator circuit for an oscillator, which will convert a modulating signal into a frequency modulated signal. The phase regulator loop in the sampling circuit will equalise the frequency of the modulated signal to that of a generated reference signal. There is a second sampling circuit (25,26) with a phase regulator loop linked to a second reference signal generator (24). This produces a second control voltage which adjusts the sensitivity of the frequency-modulator circuit.

Patent NL-8601543-A (NL)
IPC: A01G31/04
Filed: 1986-06-13
Abstract: In order to be able to use exactly the same planting table for all types of cultivations used in hothouses, the planting-table top is provided with irrigation ducts and projecting ribs, partly along the side borders and partly between the ducts. Consequently, it is made possible that the cultivation can be carried out partly using a lifting/lowering system, where the liquid is channelled in or out either over the entire table top or a part thereof, to be precise between two ribs, partly by a straightforward channel system, where an appropriate amount of water is channelled via one or more of the cultivation parts, and partly by hydroponics, where the plants are always located in separate channels in the water and where the water is constantly replenished by overflow pipes. Since the ribs are shortened in order that liquids can pass between the ducts through an uninterrupted drainage duct, it is possible, in a particularly simple manner, to channel liquid to the entire planting table by means of a valve, or channel it away therefrom. Furthermore, the ribs may be provided with holes in order that a good, uniform air circulation beneath the plants is achieved, as a result of which growth is the same over the width of the table and the plants become both stronger and healthier.
