Title: Control arrangement in a circulating fluid heating system
IPC: F24D19/10
Filed: 1980-02-01
Abstract: A heating system, such as a domestic central heating and hot water supply system, including a gas or oil fired boiler 10 and a pump 14, is provided with thermostatic valves M and 16 which control water flow in response to desired room or water temperature respectively, and a flow sensor 17. An electrical monitoring unit is arranged to switch OFF the pump 14 via a triac 22 Figure 7 for a set period determined by a timer circuit 21 Figure 7, when the boiler has been switched OFF in response to detection of low flow rate. The pump is then switched ON again for a shorter period to determine whether any of the thermostatic valves have opened permitting fluid flow which would be detected by the flow sensor -(since the sensor is inoperative if the pump is off). The sampling procedure is repeated until heat demand is detected whereupon the pump will be run continuously. This switching may be over-ridden if the boiler temperature exceeds a preset maximum, in which case the pump operates continuously. The flow rate sensor Figure 3 comprises a magnetically operated reed switch A, the magnet D moving with a spring biassed piston member C in response to flow and the reed switch being eccentrically mounted on a tube member B transverse to the flow so that rotation of the member B alters the relative positions of the magnet and the reed, and hence the sensitivity of the sensor. <IMAGE>

Title: A power brake system
IPC: B60T11/34
Filed: 1981-01-29
Abstract: In order to prolong the very short threshold time characteristic of hydraulic power brake systems and to ensure gentle commencement of braking, a brake system is proposed in which throttle valves (9) are provided in the brake lines (22, 23) leading to the hydraulic wheel brake cylinders. The throttle valves (9) are equipped with a throttle (16/17) which is closable in dependence upon brake pressure. In this manner, they do not effect the pressure rise with respect to time up to the pressure at the commencement of braking, although they become effective when the pressure at the commencement of braking is exceeded. The response time itself remains unaffected. The invention is usable preferably in hydraulic power brake systems and in compressed air brake systems having hydraulic power transmission. If a compressed air connection for a trailer is additionally provided, it is a simple matter to actuate the trailer brakes in advance of the tractor vehicle brakes. <IMAGE>

Patent GB-2079114-A (GB)
Title: Circuit arrangements for reducing media overload effects in signal recording and transmission systems
IPC: H04B1/04
Filed: 1981-06-29
Abstract: A frequency dependent circuit is located in the main signal path of a dual path compressor or expander in which the main signal path is linear with respect to dynamic range and a further path provides a signal which boosts or bucks the main path by way of a combining circuit, but which is so limited that in the upper part of the input dynamic range the further path signal is smaller than the main path signal. The frequency dependent circuit in the compressor is called an antisaturation network with a characteristic FAS such as to effect a reduction in frequency response in the frequency band affected by overload in a transmission channel fed by the compressor, typically the upper end of the overall frequency band. The expander which is fed by the channel has a complementary antisaturation circuit with a characteristic F'AS providing a complementary increase in frequency response. The arrangement provides level dependent equalization without significantly affecting the noise reduction effect of a compressor/expander system because in dual path compressors and expanders the output of the circuits at very low signal levels is provided mostly by the further path. Thus, at high levels, where channel overload is a problem, the frequency dependent circuit is effective, while at low levels, where it is not desired or needed, the equalization effect is reduced. <IMAGE>

Title: Safety valve
Inventor: LOVE NORMAN EDWOOD
IPC: F02D17/04
Filed: 1981-11-30
Abstract: A closure valve, more particularly but not exclusively for use in the air inlet conduit of an internal combustion engine, comprises a valve member movable from an open position to a closed position and biassed from the open position to the closed position, and holding means to hold the valve member in an open position against the said bias and against up to an additional predetermined fluid pressure on the member towards the closed position, pressure over the said predetermined pressure releasing the valve member from the holding means. An arm 22 fixed to the pivoted valve member (not shown) is rotated, when the valve is set in the open position, to engage behind a spring-biassed pivoted catch 36. When the air pressure acting on the valve member reaches the predetermined value it will cause the arm 22 to rotate, moving the catch 36 against the force of its spring 40. Further means 50 provides retraction of the catch 36 when oil pressure in an engine lubrication system drops. <IMAGE>

Title: Detecting fuel injector opening
IPC: F02B3/06
Filed: 1981-12-21
Abstract: In order to determine the opening of a fuel injector of, for instance, a compression ignition engine, an electro-acoustic transducer such as a contact microphone monitors the acoustic waves produced by the injector. A monitoring circuit detects when the level of the output signals of the transducer increases, this increase being indicative of opening of the injector. By comparing the opening time of the injector with the position of the crankshaft, the timing of the engine can be checked without requiring dismantling.
