Patent GB-2091856-A (GB)
Title: Training projectile
IPC: F42B10/54
Filed: 1982-01-19
Abstract: A training projectile which is stabilized by its own rotation during flight is described and comprises a conical nose section (1), a cylindrical intermediate portion (2) and a tail section. The projectile is provided with aerodynamic surfaces in the form of fins (4) or grooves (8) (not shown) on the cylindrical intermediate portion (2). The fins and grooves, respectively, extend substantially radial and parallel to the symmetrical axis (5) of the projectile. The arrangement of said fins or grooves imparts a braking effect on the projectile to reduce its rotational velocity after launching so that the projectile at a specific, critical rotational speed becomes unstable and tips or tilts. This means a substantial increase of air resistance and a corresponding reduction of the projectile velocity forwards. By an appropriate adjustment of the fins (4) and grooves (8) respectively, it is possible to locate the instability just behind the target distance when training. The ballistic properties of the training projectile are maintained up to the target distance but the maximum firing range is reduced compared with the normal live ammunition. <IMAGE>

Title: Cooling of hydrodynamic clutch-operated, brakes
IPC: F16D65/78
Filed: 1982-03-05
Abstract: A hydromechanical retarder has two clutches I, 34-36 one of which is cooled to be able to take a comparatively large slip when transmitting torque, which drive the rotor 38 of a hydrodynamic braking device. There is also a disc brake 40, 42 which is cooled and capable of continuous braking when slipping. The unit is operated by a single servo- motor 20, actuated by modulated pressure air. The unit is capable of producing practically constant braking torque over a wide speed range down to stalling. The clutch 34-36 and friction brake 40, 42 are cooled by the fluid of the hydrodynamic brake, which is cooled by fins 12 on the stator housing 10, which are cooled by the vehicle engine cooling system. A force opposing the operation of brake 40, 42 is generated by the retarder in proportion to the speed of rotation of rotor 38. <IMAGE>

Title: Sensor for determining the level of liquid gases
Inventor: ELLINGHAUS H RAINER
IPC: G01F23/24
Filed: 1983-01-20
Abstract: The electrical signal indicating the level of the liquid is given by a temperature-dependent resistor. In order to reduce ambiguity in determining the liquid level this temperature- dependent resistor is enclosed with a further resistor to which a voltage is applied. In this way, the sensor is heated more when it is located outside the liquid than when it is immersed in the liquid. Consequently there is a perceptible signal change when the sensor is immersed in or emerges from the liquid. With a system of four sensors, the level of the liquid fluctuates between the positions of the two central sensors, while the top and bottommost sensors serve to signal an alarm in the event of overflow and when the vessel is empty. A switching amplifier circuit is illustrated. <IMAGE>

Title: Method for manufacturing an insulated gate field effect transistor device
Inventor: KINSBORN ELIEZER
IPC: H01L21/336
Filed: 1983-05-31
Abstract: A method for manufacturing an IGFET device which provides IGFETs having extremely shallow source (24) and drain (25) regions and reduced gate to source and drain overlap capacitances. For silicon MOS devices, the method also provides for the formation of metal silicide layers (33) on polysilicon gate electrodes (18) and interconnection paths and the source and drain regions in the same fabrication step. Source and drain regions are formed by oxidation of an arsenic doped polysilicon source layer (17) formed to be in contact with areas in the silicon surface in which such regions are to be formed. The thickness of the source layer and the conditions of oxidation are such that the rate of oxidation of the source layer exceeds the rate at which arsenic diffuses in the silicon at the oxidation temperature and that during the oxidation time, the arsenic in the source layer diffuses into the silicon to form extremely shallow source and drain regions.

Title: Stackable container with dilutable product
Inventor: FERGUSON PETER FREDERICK
IPC: B65D85/816
Filed: 1984-12-27
Abstract: Filled containers 18 which are nestable in stacks each have a ledge 26 to which a diaphragm 12 is peelably secured to confine a product 27 beneath it, and an upper nested container is supported by a denesting ledge of the container beneath so that it does not compress the lower container's diaphragm in its region of securement. The denesting ledge 28 may be provided above the ledge 26 to support the upper container so that it is spaced from the lower diaphragm. Alternatively the upper container may rest on the lower diaphragm but not in its region of securement, and be supported through the diaphragm by ledges beneath it (formations 82: Fig. 8). A stack of containers may be packed in a carton (Fig. 7), with at each end corrugated board and foam sheeting between the stack and the carton. Containers may be filled by means of a head (Fig. 4) insertable into a container to rest on the diaphragm ledge. The ledge 26 may be sloped (Figures 3a, 3b, 3c) so that any liquid spilled thereon will tend to run off the part of the ledge to which the diaphragm is sealed, and the filling head may have suction ports for removing liquid from the ledge. <IMAGE>

Title: Floating valve member
Inventor: KIEDROWSKI THOMAS F
IPC: F16K31/22
Filed: 1985-01-08
Abstract: A valve member 22 floats in a liquid within a dispensing container 21 e.g. an IV bottle containing a saline solution. With the liquid level suitably receded the member 22 seals off the outlet of the dispensing container 21 by means of the sealing surface 26 resting on the valve seat 27. The maximum horizontal dimension of the member 22 is greater than the maximum vertical dimension so that the member is constrained to float in the attitude in which surface 26 engages seat 27. Thus surface imperfections, such as the parting line 28 and/or the gate member 30, will never engage seat 27. <IMAGE>
