Title: Electrodynamic loudspeaker with omni-directional sound radiations
Inventor: HAAS RAINER J
IPC: H04R1/34
Filed: 1985-02-15
Granted: 1988-07-28
Abstract: An electrodynamic loudspeaker for the high or mid-range sound region emits sound omnidirectionally. The loudspeaker comprises two identical individual loudspeakers arranged on opposite sides of a plane of mirror symmetry. Each loudspeaker has a drive unit with a permanent magnet fixed at a carrier part common to both sides and a moving coil means, including a winding and a bobbin, elastically held by a spider at carrier part. Each moving coil means is rigidly connected with a hemispherical membrane. The carrier part is formed as a ring and is limited by a spherical ring surface having a diameter which is somewhat smaller than twice the diameter of the outer rim of the membrane. The moving coil means has a diameter substantially the same as the outer edge of the membrane.

Title: Shock absorbing strut for aircraft undercarriage
Inventor: HANDWERK ROY R
IPC: B64C25/60
Filed: 1985-09-16
Granted: 1988-09-29
Abstract: A rapidly extendible, rough-field attenuating shock-absorbing strut, particularly adapted for use with an aircraft having a tricycle landing gear, is used during takeoff and is adapted for rapid extension to provide angular or upward momentum to the aircraft and thus facilitate takeoff. The strut comprises an outer cylinder which is secured to the aircraft and an inner cylinder adapted for longitudinal reciprocation within the outer cylinder. The inner cylinder has a wheel mounted thereon at the end opposite that of the outer cylinder. A piston is secured for longitudinal reciprocation within both the outer and inner cylinders. The piston has a piston head adapted for reciprocation within the outer cylinder. Provision is made for applying fluid pressure to the piston head to cause it to move longitudinally toward the inner cylinder and provision is made, in association with the piston and inner cylinder, for moving the inner cylinder longitudinally and away from the aircraft and outer cylinder when said piston moves toward the inner cylinder. This causes rapid extension of the inner cylinder to provide angular or upward momentum to the aircraft. Also valving is provided to allow the inner cylinder to reciprocate within the outer cylinder by altering the flow and/or amount of the fluids within the strut for shock attenuation over rough surfaces.

Abstract: In order to increase the product of the speed of rotation times the diameter of the bar stock, the inventive feed apparatus comprises, for guiding the bar stock, a plurality of bearing units constituting the non-rotary part of a hydrostatic bearing receiving oil under pressure. For introducing a fresh piece of bar stock, two rotary components of the bearing unit are capable of opening. A central passage may be either entirely closed and locked, a lever then being completely pushed back, or set ajar, for each bearing unit in sequence, so as to allow the carrier of a pusher to pass, or wide open to allow the fresh bar stock to enter, the mentioned lever then being completely pulled. The feed apparatus is particularly suitable for a computerized numerical control (CNC) automatic lathe.

Abstract: A contact sensor for detecting points on a grid where the sensor is being contacted on opposing sides by teeth surfaces or other contacting points. The contact sensor includes two sets of parallel electrodes which are each formed of a thin, flexible supporting sheet. The electrodes are coated with a thin, resistive coating. Two such electrode structures are oriented at approximately right angles to create a grid where the intersecting electrodes cross separated by the resistive coatings. The resistive coatings may be made from conventional resisitive inks and are optionally separated by a separation material, such as talcum or mesh. In the absence of an external force, the material between the electrodes sets provides a high resistance between intersecting electrodes. The novel composition of the intermediate layer results in a structure which provides a "switching" effect such that the resistance between electrodes is very high where there is no external pressure and changes to a comparatively low value at locations where external pressure is applied by two contacting points or surfaces. The sensor output is dynamic in the sense that the resistance will change back and forth between high and low resistance states as external pressure is repeatedly applied and removed. The sensor may be made extremely thin and can provide high resolution capable of distinguishing between contact points separated by 0.050 inches or less. Additionally, the sensor output may be provided by means of a small computer or similar digital processor which monitors the signals from the sensor grid and which provides an output which indicates the variation in contacting points with time.

Abstract: An illumination system is provided for a liquid crystal display panel. The panel 1 is placed to transmit light 2 from a light source 3 to a viewing location, the light source being an extended area source of omnidirectional light of high efficiency, such as a fluorescent tube. A light guide 6 is placed between the source and the panel, the light guide comprising a transparent input face 7 adjacent the source, a transparent output face 10 adjacent the panel, and reflective side walls 11 transverse to the input and output faces. The light guide is tapered, the input face being smaller in area than the output face. The divergence of light from the source is thereby reduced as it passes through the panel. The LCD panel then functions with an improved contrast range.
