Patent BG-52161-B2 (BG)
Title: Shell with built-in tracer elements
Inventor: PETKOV BOJAN M
IPC: F42B12/38
Filed: 1989-03-23
Abstract: The shell is designed for complete firing ofcombat-and-training and combat firing at direct aiming byartillery systems. The tracing elements are built in blindapertures (seats) fitted symetrically along the periphery on thebottom of the shell case which keeps the thickness of the bottomunaltered. An important design feature is the fact that thecentres of the holes in which the tracer elements are seated arefitted on a circumference having a radius equal to that of thebottom of the shell reduced by the radius of the blind aperture.Each of the tracer elements is built-in under the level of theplane of the shell bottom so that it, together with the metalwasher supporting it, fills up the whole volume of the blindaperture and the metal washers are centred in several points.3 claims, 2 figures

Title: Protective helmet for airport staff - has elastic straps pressing onto ear caps under helmet
IPC: A42B3/16
Filed: 1968-11-05
Abstract: The protective helmet is for use by ground personnel on airports. It has a stiff shell, with outwardly arched sides, extending across the ears of the wearer. Ear caps for sound proofing are suspended from the shell. an array of elastic tension straps on the inside of the shell press the ear caps against the head. Each strap is fastened at its ends to the helmet shell (1). The strap has an adjustable longitudinal tension, and stretches across the arched sides (1a), so that it presses onto the associated ear cap when the helmet is worn. Each tensioning unit has two crossed straps, and a third one, extending parallel to the sweat band of the helmet, and acting onto the upper ear cap section. One end of each strap is removable for loosening.

Title: Double cylinder lock for two keys - is actuated by one key while other key is inserted
IPC: E05B9/10
Filed: 1969-06-18
Abstract: The coupling mechanism is used for coupling two coaxial cylinder cores with key projections. Between these cylinder cores rotates the hub of the lock and it has two coupling pieces. Each of these pieces can move axially and coupled to the key. This lock is designed so that even if a key is already inserted on one side the other side can be actuated by another key. The coupling piece (19a) with circular cross section is opened towards the associated cylinder core (6a) whose inner cylindrical surface acts as guide for the corresponding plunger (18a). A sleeve (22) is connected to this coupling piece and a compression spring is fitted between the free end of the sleeve and the plunger of the other coupling piece. Its spring constant is lower than that of the inserting springs (20a) fitted between the coupling pieces and the plungers.

This is in parallel with a smoothing capacitor (8)and has one terminal connected with a D.C. amplifier (3) fed from a constant low voltage D.C. source. The amplifier output is connected with the base terminal of a field-effect transistor (4), the emitter of which is connected with a high resistor (5) and the collector to a capacitor (6) and to the emitter of a double-base terminal transistor (7). The other end of the capacitor (6) and one base of the transistor (7) form the input to the rotary winding of an inductive rotary converter.

Title: Earthing circuit for noisy radio communications signals - cancels residual signal across earthing contacts with small induced signal
IPC: H04B1/74
Filed: 1971-07-07
Abstract: The earthing circuit earths communications signals when their noise reaches an unacceptably high level. The load (Z2) is coupled to the signal path (Z1) via a transformer (L) whose two windings are connected in series and inductively coupled. The two windings have opposite phase senses. Relay contacts (aI, aII) connect the ends of the winding (W1) on the signal path side to earth when the noise reaches a given magnitude. When both contacts are closed a small a.c. voltage is induced in the load side. This voltage has the opposite phase to residual signals across the contacts and therefore cancels with them. The circuit covers 0.3-8 MHz.

Title: Speed control circuit for DC motor supplied from AC mains - has comparator controlling thyristor via limiters and triggers for operation from two static converters
IPC: H02P7/293
Filed: 1971-11-04
Abstract: The speed control circuit, for a dc motor supplied from two or more static converter bridges coupled to an ac supply, has a comparator comparing a reference value with the actual value of a parameter (e. r. current) of the motor. The output of the comparator is passed over 3 amplifiers and 3 limiters to 3 pairs of triggers. Each pair of triggers controls the two thyristors in each of the 3 converter bridges coupled to the 3 secondaries of the mains transformer. Constant current sources are connected to the inputs of the triggers. The limiters and constant current sources have different limits and current respectively. This avoids the use of staged Zener diodes.

Patent JP-H078121-B2 (JP)
IPC: H02K1/27
Filed: 1985-01-28
Abstract: A single-phase synchronous motor with a two-pole permanent-magnet rotor of a magnet material having a remanence Br, a specific density rho , a rotor diameter d, a resulting detent torque of an amplitude Mk1, and a mass moment of inertia J. In the single-phase synchronous motor, high-energy magnet materials are used for the rotor, which rotor material is characterized by the constant   <IMAGE>   The moment of inertia J and/or the detent torque Mk1 should be influenced in such a way that the natural frequency   <IMAGE>  of the low-amplitude freely oscillating system comprising the rotor and the load is unequal to the mains frequency  omega e. In the design of a single-phase synchronous motor this may result in, for example, the air gap at the narrowest point being enlarged in comparison with the dimensions of conventional motors having rotors with conventional permanent magnet materials.

Abstract: The invention relates to a delivery device for running yarns, having a rotationally fixed storage drum (4), to which the yarn (F) can be fed from the rear by means of a yarn guide (5) rotating in one direction of rotation or the other and from which the yarn (F) can be drawn off overhead, said storage drum (4) being assigned webs (26) which serve for transporting the laid-on yarn turns towards the head end and which, irrespective of the direction of rotation of the yarn guide (5), always ensure a transport towards the head end of the storage body. For the purpose of achieving the best possible mode of operation, the invention proposes that the adjustment for adaptation to the direction of rotation of the yarn guide (5) results automatically from the driving force of the yarn-guide drive shaft (3). <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To ensure reliable working of a push rod and also reduce a friction loss of a rotary member by which oil in a working chamber is scattered, by forming an oil sump, which is opened to the edge of the working chamber side of a bottom wall of a cam chain chamber, in an engine body, and communicating it to the inside of the working chamber through a restriction hole. SOLUTION: A ring gear 121 is rotated in a working chamber 106, and oil in the working chamber 106 is stirred and scattered by the ring gear 121. An oil sump 137 for gathering scattered oil, which is opened to the edge of the working chamber 106 side of a bottom wall 124a of a cam chain chamber 124 where a cam chain 127, wrapped on a driving sprocket 125 and a driven sprocket, is run, is formed in an engine body 34. Besides, the oil sump 137 is communicated to the inside of the working chamber 106 through a restriction hole 149, therefore, during the operation of the engine, the level of oil in the working chamber 106 is reduced, because a part of the oil is gathered in the oil sump 137. Consequently, a friction loss caused by the rotation of the ring gear 121 can be reduced.

The resulting preformed body 2 is disposed in a metal mold 3, and molten Al or Al alloy 1 is poured around the preformed body 2. Then, a pressurizing force is impressed by means of a plunger 6, etc., on the poured molten Al 1, and the molten Al 1 is pressed and impregnated into the preformed body 2 so as to form a magnetic composite material. Since this composite material has high magnetic properties, it can contribute toward making magnetic substances, etc., for motor rotor and stator lightweight.
