Title: A hand pump for operating an atomizer
Inventor: BADEWIEN REINHARD
IPC: B05B7/24
Filed: 1986-10-08
Abstract: A hand pump for operating an atomizer, more particularly the atomizer of an inhaler, comprises a pump cylinder (7) and a piston guided therein. One end of the pump cylinder (7) is secured to a baseplate (2) so as to be pivotable around an axis (8) aligned transversely to the stroke of the piston. A lever (6) is pivoted at (5) to the baseplate (2) and the free end of the piston rod (9) projecting from the cylinder (7) is likewise secured to the pivoted lever (6). It is thus possible to use piston-cylinder units in which the swept volume has a large cross-section and the stroke can be kept correspondingly short, to avoid excessive dimensions. The increased power required for the pump is compensated by the power transmission resulting from the lever arm ratio through linking the piston-rod (9) to the pivoted lever (6). <IMAGE>

Title: Uniformly coated electrical components
Inventor: TRUSSLER GEOFFREY ARNOLD
IPC: B05D1/14
Filed: 1987-01-19
Abstract: An electrical component 10 is coated by first spraying it with a silicone-modified epoxy then blowing milled glass-fibres onto the coating using a flocking gun 21. The component 10 is then air dried and excess fibres are removed with an air jet. After oven drying, the component 10 is dipped into the epoxy and withdrawn slowly. The component is again blown with fibres and dried followed by another dipping process and oven drying at higher temperature. The layer of fibrous material retards the flow of the resin so as to improve the uniformity of coating thickness, particularly over the corners and edges of the component. <IMAGE>

Title: Gyroscopic propulsion and levitation
Inventor: ASPDEN HAROLD
IPC: G01C19/00
Filed: 1987-09-12
Abstract: By applying torques which cause an offset gyroscope to precess with a component of precessional motion in a vertical direction it is possible to deploy energy from the spin of a flywheel 9 and exchange this with the gravitational potential of the flywheel. This known and demonstrable phenomenon can be used in propulsion systems, finding particular use in systems that can levitate. The invention provides a particular method of supplying the control torque to the flywheel shaft 22 via linkages 26 and 27, one of which incorporates hydraulic means for adjusting the force producing torque. By rotationally adjusting arms 29 and 30 in opposite directions about the central axis of a vehicle the gyroscopic precession is caused to have a controlled lift action communicated through the frame members 17 and 18. The vehicle illustrated includes a passenger and crew compartment 12 that is circular about the central axis. There are three flywheel systems radially spaced around the central axis. Fuel from compartment 13 may be used to power engines 20 to sustain the spin of the flywheels. <IMAGE>

Title: Preventing overheating of a mobile radio transmitter
Inventor: KATSUYAMA TSUTOMU
IPC: H04B1/04
Filed: 1987-10-28
Abstract: An output power control circuit is provided in a casing of a mobile radio apparatus together with an automatic power control circuit and an RF signal amplifier. The output power control circuit applied level control signals to the automatic power control circuit for maintaining the power level of the output RF signal of the RF amplifier at one of a plurality of output power levels corresponding to the level control signals. The output power control circuit has a receiver, a temperature sensing circuit and a logic circuit. The receiver receives RF signals transmitted by a master station and detects power level setting command signals included in the received RF signal. The temperature sensing circuit detects an internal temperature of the casing and provides a power reduction signal upon detecting that the internal temperature has exceeded a predetermined temperature. The logic circuit receives the power level setting command signal from said receiver, and generates a level control signal for determining an output power level corresponding to the power level setting command signal, and generates a level control signal for determining an output power level which is lower than that specified by the power level setting command signal upon receiving the power reduction signal from the temperature sensing circuit.

Patent GB-2231692-A (GB)
Title: Heat pump heating apparatus
Inventor: KAWAI NOBUO
IPC: F24D19/10
Filed: 1990-04-27
Abstract: A compressor 3 included in a refrigerating cycle of a heat pump heating apparatus is operated at a speed corresponding to a blowoff temperature Tb so that the temperature of air blown off into a room through an indoor fan 7 from a condenser 4 is controlled to a set value Tc when a room temperature is is less than its set value is. When the room temperature Ta is much lower than its set value is the fan 7 is operated to provide a relatively high airflow. When the room temperature is closer to its set value the fan 7 is operated to provide a relatively small air flow, thereby ensuring that an occupier of the room does not feel chilled. A timer 25 may provide a delay such that the compressor speed only changes when the blow-off temperature Tb exceeds an upper or lower limit for longer than a set time.

Filed: 1990-12-05
Abstract: Cigarette perforating apparatus comprises a rotary stepped reflector (5) for directing an incident laser beam (2) along a reflected path (2R) to produce axially spaced perforations on a cigarette.

Filed: 1992-03-17
Abstract: An apparatus for generating and scanning a machine readable binary code includes a central processing unit which receives an electronic executable binary code and generates an optically machine readable binary code in response thereto. The optically machine readable binary code includes data formed as a matrix in the language of the electronic executable binary code. The central processing unit directly converts the internal electronic executable binary code to a visual binary code without the use of a look up table.
