Title: Injection gun (spray gun) for injecting (spraying) liquid or plastic materials
Inventor: KOPP VOLKER
IPC: B05B15/652
Filed: 1986-02-25
Granted: 1987-06-11
Abstract: The injection gun has a housing (1) with a handle (2) and an attachment (3) for connection to a tank for material to be sprayed (injected). On the front part of the housing (1) there is attached a nozzle arrangement (8) which contains a tube (12) which is flexible essentially without kinking, a nozzle head (13) and a protective jacket (14) surrounding the tube (12). In the nozzle arrangement (8) there is arranged a nozzle needle-valve (17) which is flexible essentially without kinking and extends from the nozzle orifice to the nozzle head (13) and through a connection part (5). In the attachment there is mounted a non-return valve (27) so that a chamber closed with respect to the atmosphere is produced between the nozzle orifice and the non-return valve (27) to prevent reaction of the material to be injected with the ambient air. This injection gun is suitable for foam-filling cavities. To carry out surface coating, a second nozzle arrangement may be fitted on the injection gun to obtain an atomisation effect by means of compressed air which is fed via the handle (2). <IMAGE>

Granted: 1989-03-30
Abstract: A simple fail-safe digital filter is to be created for monitoring an input signal which is subject to tolerances, which can be constructed of non-safe filters and which can be used for monitoring the significant errors of an input signal. According to the invention, the filter is constructed of more than three, preferably four identical mutually parallel and intrinsically non-safe filter channels (I to IV) which are ANDed (5) at the output end, the filter channels (I to IV) being supplied with derived pulses (1) of the differentiated rectified input signal (f) for monitoring the frequency and duty ratio of the input signal (f), which filter channels cause a subsequent channel monostable flip flop (18) to output a continuous-1 signal (7) as long as these pulses (1) fall within the defined window time ( DELTA t) of a 2nd filter monostable flip flop (17) which is controlled by a preceding 1st filter monostable flip flop (16> and, for monitoring for pulse overshoots and break-HAZARDS, each of the filter channels (I to IV) is connected in parallel with an arrangement in which detector monostable flip flops (22, 23) respond to irregularly collapsing edges of the input signal (f) during defined test times (ttest) of preceding monostable flip flops (20, 21) and activate a turn-off monostable flip flop (24), the signal (6) of which turns off the associated channel monostable flip flop (18). <IMAGE>

Patent DE-4207828-C1 (DE)
IPC: F42B3/08
Filed: 1992-03-12
Granted: 1993-08-26
Abstract: A shaped charge (3) has a liner (6a), which is constructed open on both sides, in its charge cavity (4). The cavity (4), which is lined in such a way, is closed (7, 10), until the charge is initiated, both in the region of the lining base (6b) and in the lining region (6c) remote from the base, and is completely filled with a medium (11) which can flow. The closure (7) in the lining region (6c) remote from the base is used, in the event of initiation by displacement at the correct time of medium (11) which can flow out of the cavity centre, to create a space for the shaped-charge jet to form in from medium (11) which can flow but is not displaced.

Inventor: SOROKIN ALEKSEJ P
IPC: A61B5/02
Filed: 1986-10-03
Granted: 1997-10-10
Abstract: FIELD: sports medicine. SUBSTANCE: sportsmen are subjected to echocardiographic examination for measuring following parameters: aorta size, left ventricle size at moment of diastole, thickness of left ventricle's myocardium. Parameters thus-measured are used to calculate left ventricle's myocardium weight (mass) using conventional formula. Next heart's beat rate and arterial pressure in rest state are measured, followed by veloergometric testing. Extent of load is measured in such manner that period of reaching peak load be terminated at 4th minute of load and that sportsman heart's beat rate would not go beyond 200 minus sportsman age in years, arterial pressure not exceeding 200 mm Hg. Load duration is determined individually on basis of completion of first stable condition in terms of heart's beat rate and arterial pressure. As soon as load is taken off, heart's beat rate and arterial pressure are measured again, followed by calculating per-minute volume index conventional formula. With following relationships: aorta size ≥ 2.8 cm, left ventricle's myocardium weight ≥230 g, per-minute volume index ≥ 5.5 conclusion is drawn, whether given sportsman is promising or not for such or such specific sports activities. EFFECT: method accuracy is enhanced by 42 %. 2 cl

Granted: 1994-07-15
Abstract: FIELD: electrical engineering. SUBSTANCE: surge of voltage appearing across terminals of electric motor with switching has complex alternating shape. In protection unit built on three-phase rectifier diodes 4, 6, 8 let pass negative half-waves of voltages and diodes 5, 7, 9 - positive ones. Silicon stabilizer diodes 11, 12 are used to limit surges of voltage from "top" and "bottom". With action of surges of voltage exceeding level of stabilization voltage of silicon stabilizer diode current through stabilizer diode increases abruptly, resistance of stabilizer diode diminishes shunting oscillatory system composed of winding and stray capacitances, reducing factor of merit and sharply limiting emerging surges of voltage. Resistors 13 limit maximum pulse currents through stabilizer diodes protecting them against break- through by great current. EFFECT: increased efficiency of protection against switching voltage surges. 1 dwg
