Title: Controlling amplifier power supply in dependence on signal level
Inventor: YANG JEANNIE LAY ENG
IPC: H03F1/02
Filed: 1994-02-09
Abstract: The invention relates to a main power supply circuit including a rectifier and a loading capacitor providing an operating voltage for a power amplifier fed by a signal. It is an object to reduce the size and heat dissipation of said power amplifier. There is inserted between the output of said rectifier 5 and said loading capacitor 7 a thyristor 6 being fired by a gate pulse G the time position of which within main voltage period is controlled in dependence from the amplitude of said signal (L, R). Especially for an audio output power amplifier within an audio or television broadcast receiver. An alternative embodiment uses a switched mode power supply instead of the thyristor. <IMAGE>

Title: Castors for trolleys
Inventor: CUNNINGTON BRIAN JOSEPH
IPC: B60B33/02
Filed: 1994-02-22
Abstract: The invention relates to a castor for mounting a wheel 30 on a trolley, the castor being biased towards a single stable position on its swivel axis. Preferably such castors are used to mount the rear two wheels of a trolley with the wheels 30 aligned for forward motion of the trolley i.e. with the wheel trailing. This enables the trolley to be steered more easily. For biasing, a cam follower roller 16, associated with the filling for connecting to the trolley, is biased against a cam surface 22 on the filling 20 for mounting the wheel 30. The cam surface 22 may have a detent 22a at a position corresponding to the wheels preferred position and be circular around the rest of its circumference. The force biasing the cam follower roller 16 may be increased with the compressional force between the fillings by way of a bell crank lever mounted to the trolley filling, with one arm contacting the other filling and the other arm being arranged to compress the spring 15 which provides the force biasing the cam follower roller 16 against the cam surface 22. <IMAGE>

Title: Method of preheating hydraulic fluid
Inventor: HOANG BONG DONG
IPC: F15B21/0427
Filed: 1991-10-24
Abstract: In a system to preheat the hydraulic fluid of an actuator system eg of a heavy construction vehicle, valves in the hydraulic system are operated so that the temperature of the hydraulic fluid output by the main pumps is caused to rise by virtue of pressure loss occurring due to a resistance generated between the hydraulic fluid and relief valves as the hydraulic fluid passes through the relief valves. The preheating of the hydraulic fluid is only effected when the temperature of the hydraulic fluid T is below a set value and when no operation of the hydraulic system is being requested  theta i = 0. Also disclosed is a system for automatically starting the engine of the construction vehicle (figure 6) and a system for controlling the temperature of the hydraulic fluid and engine coolant by regulating the engine speed in response to the measured temperatures of the hydraulic fluid and engine coolant (figure 3). <IMAGE>

Title: Audio bit-stream generator
Inventor: GOH YONG CHEUL
IPC: H04N7/52
Filed: 1995-03-02
Abstract: An audio bit stream generator for an HDTV which can be used to develop an audio decoder without manufacturing an audio encoder. By utilizing a PC, a bit stream is prepared by encoding through computer simulations and by using a data compressing algorithm for an HDTV. This data is stored on a hard disc, and output at a certain audio transmission rate, thereby simulating an HDTV audio encoder. This avoids the expense of procuring or manufacturing an expensive audio encoder. The system can also be applied to a digital apparatus for data compression. <IMAGE>

Title: Power adaptor with integral radio frequency port
Inventor: DEMURO DAVID MARK
IPC: H04B1/38
Filed: 1994-12-05
Abstract: The present invention provides a power adapter (10) adapted to couple an external antenna (17) to a communication device (30) by way of a cable (12) which is typically plugged into a cigarette lighter of a vehicle or some other power source at one end, and an input connector of the communication device (30) at the other. In particular, the present invention provides a simple one-piece vehicle power adapter which also provides RF input/output capability for connection to an external vehicle antenna. According to certain aspects of the invention, the adapter can be configured to have a variety of selection mechanisms. For example, the communication device could include an RF switch (34) and control circuitry for selecting either the internal or external antenna for optimum reception. Alternatively, the cable could include an external switch (70) for allowing the user to select the desired antenna. Finally, the cable could include a component which automatically actuates the switch to select the external antenna when the external antenna is connected to the communication device. <IMAGE>

Title: Piling
Inventor: CHAN KWONG YEE
IPC: E02D5/68
Filed: 1996-07-10
Abstract: In the manufacture in situ of secant piles, the secondary piles 4 are formed individually by the use of cylindrical forms 14. When each form has been excavated to the desired depth, at least one longitudinal former 12 is placed in the form in parallel with its axis and close to the inner wall of the form. The cross-sectional shape of the former is chosen so that, when the form has been filled with concrete; the concrete has set, and the form has been removed axially, the resultant secondary pile has in its convex surface a longitudinal recess having at least a partially-cylindrical concave surface. When two such piles have been formed, a similar form 14 may be driven along their length by contact with the recesses, and the complementary primary pile 2 manufactured. Preferably the form for the primary pile is withdrawn at least partially while the concrete has not fully set, so that concrete from the pile is able to slump and fill the space left between the pile and each adjacent secondary pile by the withdrawal of the form.
