Title: Dual force fluid actuated shift device
Inventor: GENISE THOMAS ALAN
IPC: F16H61/30
Filed: 1993-07-20
Abstract: A fluid operated shift actuator (11) is provided, and is especially suited for use in an X-Y shift mechanism for a change-gear mechanical transmission. The shift actuator includes a piston rod (47), a piston member (87), and a pair of auxiliary pistons (93 and 95), to define fluid pressure chambers (91 and 92).

Patent ZA-989580-B (ZA)
Title: Automatic syringe
Inventor: TSALS IZRAIL
IPC: A61M/
Filed: 1998-10-21
Abstract: A syringe comprises a barrel containing an internal cylindrical body containing a liquid and communicating with a delivery needle. The needle is covered before use by a removable sheath, and after the sheath is removed, the needle is concealed by a displaceable sleeve. In use the sleeve is pressed against the skin by applying pressure while holding the barrel. The sleeve is thereby retracted into the barrel allowing the needle to penetrate the skin. The movement of the sleeve also activates a gas generator which expels the liquid from the needle. When delivery is complete and the syringe is taken from the skin, a coil spring moves the sleeve back to the starting position again concealing the needle. The coil spring is torsionally biased before use and causes a rotational movement of the sleeve relative to the barrel when the sleeve moves into and out of the barrel. This rotational movement engages a locking mechanism which prevents further movement of the sleeve and thereby permanently conceals the needle.

Title: Method of reacting carboxylic acids
Inventor: WATTS PAUL
IPC: C25B3/29
Filed: 2002-09-12
Granted: 2006-03-08
Abstract: Electrical voltage is applied between ends of a channel containing a liquid and carboxylic acid molecules (I,II) having carbon atom alpha to carboxylic acid group are supplied to channel. Electrical voltage makes carboxylic acid molecules to react, carboxylic acid groups are lost, and product molecule is formed in which alpha carbons are bonded. The reaction takes place in liquid in the channel and spaced from electrodes. Electrical voltage is applied between opposite ends of a channel containing a liquid using electrodes and carboxylic acid molecules (I,II) having carbon atom alpha to carboxylic acid group are supplied to the channel. The electrical voltage makes the carboxylic acid molecules to react with the loss of carboxylic acid groups. A product molecule is formed in which alpha carbons are bonded. The reaction takes place in the liquid in the channel and spaced from the electrodes. Carboxylic acids are thus reacted.

Granted: 1990-02-14
Abstract: A heating and/or cooling system having a system controller (10) and a number of heating and/or cooling sources (2-1, 2-2, 2-n), which may be multi-stage heat pumps, the heating and/or cooling sources (2-1, 2-2, 2-n) being operated in parallel with respect to the delivery of the heated or cooled working medium. Each of the sources (2-1, 2-2, 2-n) is controlled by an individual controller (5-1, 5-2, 5-n) which is issued with demand signals from the system controller (10). The system controller (10) commands the sources (2-1, 2-2, 2-n) to increase or decrease their heating or cooling capacity by comparing the temperature of mixed working medium from the parallel outlets (6) of the sources (2-1, 2-2, 2-n) to preset reference values. The system controller (10) sequentially energises or de-energises the sources (2-1, 2-2, 2-n) so that at any time the only minimum number of sources (2-1, 2-2, 2-n) which can satisfy the heating and/or cooling demand are energised.

Title: Transmission device with low power consumption and a small-scale circuit
Inventor: MATSUKI TORU
IPC: H04Q7/30
Filed: 1997-07-23
Granted: 2000-10-25
Abstract: In a transmission device for use in a base station of a mobile communication system each of a predetermined number N of baseband signal producing sections produces a baseband signal from data signals. A baseband signal combining section 3 combines the baseband signals. Responsive to the combined baseband signal, a modulation circuit 4 modulates a carrier signal. A distributing circuit 7 distributes the modulation signal to a preselected number M of power amplifying circuits, respectively. Each power amplifying circuit amplifies the distributed modulation signal and produces an alarm signal when a failure occurs. A combining circuit 9 combines the amplified signals into the transmission signal. A control section controls the baseband signal producing sections in response to the alarm signal from each power amplifying circuit to increase a level of the combined baseband signal so as to compensate for a decrease in power of the transmission signal due to the failure occurred in a power amplifying circuit.
