Title: Cages suitable for rearing molluscs
Inventor: HAWKYARD PETER ADRIAN
IPC: A01K67/033
Filed: 1990-01-24
Abstract: Apparatus for rearing molluscs and the like comprises a hollow cylindrical body 1 formed by joining-together semi-cylindrical components of transparent plastics material. The body is divided into a plurality of sections by divider walls and thus provides a number of cages for molluscs. The semicylindrical components are joined together with slight gaps 19, 20 therebetween, which provide ventilation and, in the case of the lower gap 20, drainage outlets to a gutter 21. A rotatable water spray pipe 13 passes axially through the body 1. <IMAGE>

Patent GB-2228574-A (GB)
Title: Proximity sensor
Inventor: TIRKEL ANATOL
IPC: G08B13/26
Filed: 1990-03-14
Abstract: A proximity sensor that employs an electrostatic sensing element (30) driven by an oscillator (26) is described, in which a disturbance of the electromagnetic field surrounding the sensing element is sensed by detecting small variations in the effective capacitance of the sensing element. An artificial disturbance of the field, of the kind the sensor is designed to sense, is discriminated from natural disturbances, of the kind caused by environmental drift, by measuring the effective time rates of change of said disturbance and comparing the measured value to an alarm threshold value. A microprocessor based control device (22) is employed to measure the effective time rates of change of the digital signal , representative of the detected capacitance variations of the sensing element (30), and to provide other control functions for the sensor, such as calibration on start-up and periodic recalibration during normal operation. The sensing element (30) is provided with an interface (28) in the form of a tuned circuit which is maintained near resonance by a voltage controlled capacitor (32). Maximum sensitivity of the sensor to capacitance variations of the sensing element (30) is maintained using a programmable voltage source (34) under the direct control of processor (22). Processor (22) employs a cascade of digital Finite Impulse Response (FIR) filters (48), configured as low-pass filters, to measure the effective time rates of change of the digital signal. A security sensing system is also described in which a plurality of the proximity sensors are controlled by a monitor using an RF communications link.

Title: Compacting machine including a wheel
Inventor: SENGER MATT NORBERT
IPC: E02D3/032
Filed: 1990-03-23
Abstract: A compacting machine for compacting material placed in a trench. A wheel is mounted on a frame 1, 2, 14, 15, and the wheel is vibrated. The wheel has a hub 10 rotatably supported on the frame, a rim 12 of uniform width, and a radially extending portion 11 interconnecting the rim 12 and hub 10. The hub 10 and a portion 14 of the frame which extends radially from the hub 10 do not project beyond the planes of circles defined by the two edges of the rim 12. As a result, the wheel can be lowered into a trench within which it is a tight fit to a depth greater than half the diameter of the wheel. Rotation of a motor-riven shaft 4 and an eccentric weight 5 mounted thereon causes the frame and the wheel to vibrate. Speed of rotation of motor 6 may be varied to adjust frequency of vibration. Plate 2 is removably fixed to adjust its distance from the other plate 2 on the right of figure 1. <IMAGE>

Title: Catalytic converter heating arrangement for internal combustion engines with a burner system
Inventor: HARTEL GUNTER
IPC: F01N3/20
Filed: 1994-01-18
Abstract: In a catalytic converter pre-heating arrangement for an internal-combustion engine, the engine exhaust system of which includes a catalytic converter equipped with a pre-heating burner, which burner is operated according to a control and regulation program in the cold-running phase of the internal-combustion engine after start up, the invention provides that the catalytic converter (2) is formed by two converter elements (4, 5) between which there is a converter chamber (6), and in that the hot emissions from the burner enter the converter chamber (6) and mix there with the exhaust gas from the internal-combustion engine and heat the converter element (5) which is second in line in the direction of engine exhaust gas flow. Accordingly, the first converter element, which is on the upstream side in terms of engine exhaust gas flow, and which is liable to impairment due to aging, is by-passed by the hot emissions from the burner, which are employed efficiently and rapidly to bring the second catalytic converter element 5 up to working temperature. <IMAGE>
